From 2566f8c2b4c67c4042c7365034bb1401378f2657 Mon Sep 17 00:00:00 2001 From: Elie Gambache Date: Thu, 23 Jul 2026 22:09:35 +0300 Subject: [PATCH 001/233] feat(packaging): embed & sign macOS app extensions (.appex) via appExtensions DSL Add a macOS { appExtensions { } } DSL to embed prebuilt .appex bundles into Contents/PlugIns, each signed with its own entitlements and (optional) provisioning profile, then seal the outer app without --deep so the extension keeps its distinct signature. Covers the JVM/jpackage path, the DMG/PKG re-seal (electron-builder), and GraalVM native images. Adds the macos-appex-demo example. No behavior change when appExtensions is unused (all new paths are guarded). --- examples/macos-appex-demo/README.md | 86 +++++++++++++++++ examples/macos-appex-demo/build.gradle.kts | 83 ++++++++++++++++ .../packaging/app.entitlements | 29 ++++++ .../packaging/extension/FilterDataProvider.m | 34 +++++++ .../packaging/extension/Info.plist | 31 ++++++ .../extension/NetworkExtension.entitlements | 20 ++++ .../packaging/extension/build.sh | 35 +++++++ .../dev/nucleusframework/appexdemo/Main.kt | 94 +++++++++++++++++++ .../dsl/MacAppExtensionSettings.kt | 89 ++++++++++++++++++ .../application/dsl/PlatformSettings.kt | 22 +++++ .../internal/configureGraalvmApplication.kt | 72 ++++++++++++++ .../internal/configureJvmApplication.kt | 12 +++ .../AbstractElectronBuilderPackageTask.kt | 72 ++++++++++++++ .../application/tasks/AbstractJPackageTask.kt | 73 ++++++++++++++ settings.gradle.kts | 1 + 15 files changed, 753 insertions(+) create mode 100644 examples/macos-appex-demo/README.md create mode 100644 examples/macos-appex-demo/build.gradle.kts create mode 100644 examples/macos-appex-demo/packaging/app.entitlements create mode 100644 examples/macos-appex-demo/packaging/extension/FilterDataProvider.m create mode 100644 examples/macos-appex-demo/packaging/extension/Info.plist create mode 100644 examples/macos-appex-demo/packaging/extension/NetworkExtension.entitlements create mode 100755 examples/macos-appex-demo/packaging/extension/build.sh create mode 100644 examples/macos-appex-demo/src/main/kotlin/dev/nucleusframework/appexdemo/Main.kt create mode 100644 plugin-build/plugin/src/main/kotlin/dev/nucleusframework/desktop/application/dsl/MacAppExtensionSettings.kt diff --git a/examples/macos-appex-demo/README.md b/examples/macos-appex-demo/README.md new file mode 100644 index 000000000..64b69e319 --- /dev/null +++ b/examples/macos-appex-demo/README.md @@ -0,0 +1,86 @@ +# macOS Network Extension (`.appex`) demo + +Reproduces the scenario from [issue #394](https://github.com/NucleusFramework/Nucleus/issues/394): +shipping a macOS **Network Extension** (`.appex`) inside a Nucleus JVM app, embedded under +`Contents/PlugIns/`, **signed with its own entitlements** (distinct from the host app). + +Nucleus embeds and signs the extension for you via the `appExtensions {}` DSL: + +```kotlin +macOS { + entitlementsFile.set(file("packaging/app.entitlements")) // host-app entitlements + appExtensions { + extension("NetworkFilter") { + appex(file("build/appex/NetworkFilter.appex")) // prebuilt .appex + entitlements(file("packaging/extension/NetworkExtension.entitlements")) // ITS OWN + // provisioningProfile(file("packaging/NetworkFilter.provisionprofile")) + } + } +} +``` + +Under the hood the plugin copies the `.appex` into `Contents/PlugIns/`, embeds its provisioning +profile (as `Contents/embedded.provisionprofile` inside the extension), signs the extension with +its own entitlements, then seals the outer app **without `--deep`** — so the extension keeps its +distinct signature.

Removes the three AWT-based modules (`decorated-window-awt`, `-jbr`, `-jni`) with their native sources, API dumps, detekt baselines and GraalVM metadata, plus the `jni-demo` sample. BREAKING CHANGE: `NucleusBackend`, `LocalNucleusBackend`, the `backend =` parameter of `nucleusApplication`, `NucleusApplicationScope.backend` and `NucleusWindowUnsafe.awtWindow` / `awtDialog` are gone, as are the AWT overloads of `MaterialDecoratedWindow` / `MaterialDecoratedDialog` (M2, M3) and `JewelDecoratedWindow` / `JewelDecoratedDialog` — only the `NucleusApplicationScope` receivers remain. Compose Desktop's AWT `Window`, `Dialog` and `Tray` are unsupported; use `DecoratedWindow`, `HostedWindow` / `HostedDialog` and an AWT-free tray. - nucleus-application: drops the AWT scope/window/dialog adapters and takes `api(project(":decorated-window-tao"))`, since the backend is no longer a consumer choice and a missing runtime module would only fail at launch - material2: ports `MaterialDecoratedDialog` to a `NucleusApplicationScope` receiver — it existed only in AWT form, so M2 keeps parity with M3 - removing the AWT overloads also retires the `LowPriorityInOverloadResolution` / `INVISIBLE_REFERENCE` workarounds they needed - taskbar-progress-tao: single Tao dispatch path - core-runtime keeps `WindowBackend.Awt`: it still describes a plain Compose Desktop / Swing host embedding Nucleus libraries - scheduler-demo moves to Tao (drops the `java.desktop/sun.*` add-opens); service-management-demo swaps `java.awt.EventQueue` for `rememberCoroutineScope().launch`, as SMAppService completion handlers must hop to the Tao main thread - drops the now-unused `jbr-api` catalog entry, the jni/jbr native build steps and verify entries from CI, and rewrites the backend docs - also adds `rect-stress-demo` / `widget-demo` to `apiValidation.ignoredProjects` alongside the other demos, fixing their pre-existing `apiCheck` failures ---

Enable ClearType end to end without runtime reflection: - plugin: LcdTextDefaultTransform (artifact transform + ASM) patches FontRasterizationSettings.PlatformDefault in ui-text-desktop jars on non-test runtime classpaths — SubpixelAntiAlias on Windows, opt-outs -Dnucleus.text.lcd=false (runtime) / -Pnucleus.text.lcd.patch=false (build). Android/HotReload/KMP guards mirror the CleanNativeLibs transform; referenced ctor/enum fields are verified so Compose layout drift fails the build. Canary test patches both the plugin's Compose and the consumer version from the root version catalog. - tao: lcdSurfaceProps attaches the OS-queried pixel geometry (cached, RGB/BGR, grayscale on any unknown) to opaque Windows window surfaces only; per-pixel-alpha surfaces (popups, NativeView overlay, Mica or Acrylic backdrops, transparent windows) keep unknown geometry so Skia falls back to grayscale. renderGlFrame now requires windowTransparent. - jewel-demo: use JewelDecoratedWindow instead of hand-rolled theming. --- .gitignore | 3 + .../tao/ffi/NativeTaoWindowsDecoBridge.kt | 12 + .../tao/popup/TaoPopupSceneLayerLinux.kt | 3 + .../tao/popup/TaoPopupSceneLayerWindows.kt | 2 + .../tao/popup/TaoStandalonePopupHost.kt | 2 + .../tao/popup/TaoStandalonePopupHostLinux.kt | 3 + .../window/tao/scene/GlSceneRenderer.kt | 29 +- .../window/tao/scene/LcdText.kt | 55 +++ .../tao/scene/TaoComposeSceneHostLinux.kt | 12 +- .../tao/scene/TaoComposeSceneHostWindows.kt | 21 +- .../native/windows/nucleus_tao_windows_deco.c | 43 ++ .../reachability-metadata.json | 4 + .../tao/StandalonePanelNativeSmokeTest.kt | 10 + .../window/tao/TaoSceneTestBattery.kt | 17 + .../tao/TaoSceneTestBatteryDriftTest.kt | 5 + .../window/tao/scene/LcdTestTextStyle.kt | 35 ++ .../window/tao/scene/LcdTextCaptureTest.kt | 179 ++++++++ .../window/tao/scene/LcdTextTest.kt | 132 ++++++ .../window/tao/scene/TaoSceneTestHarness.kt | 12 +- .../src/main/kotlin/jewelsample/Main.kt | 79 ++-- .../internal/configureJvmApplication.kt | 5 + .../transforms/LcdTextDefaultTransform.kt | 399 ++++++++++++++++++ .../transforms/LcdTextDefaultTransformTest.kt | 110 +++++ .../plugin/test-analysis-libraries.gradle.kts | 38 ++ 24 files changed, 1131 insertions(+), 79 deletions(-) create mode 100644 decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/scene/LcdText.kt create mode 100644 decorated-window-tao/src/test/kotlin/dev/nucleusframework/window/tao/scene/LcdTestTextStyle.kt create mode 100644 decorated-window-tao/src/test/kotlin/dev/nucleusframework/window/tao/scene/LcdTextCaptureTest.kt create mode 100644 decorated-window-tao/src/test/kotlin/dev/nucleusframework/window/tao/scene/LcdTextTest.kt create mode 100644 plugin-build/plugin/src/main/kotlin/dev/nucleusframework/desktop/application/internal/transforms/LcdTextDefaultTransform.kt create mode 100644 plugin-build/plugin/src/test/kotlin/dev/nucleusframework/desktop/application/internal/transforms/LcdTextDefaultTransformTest.kt diff --git a/.gitignore b/.gitignore index 907f4767b..3f5f98b4a 100644 --- a/.gitignore +++ b/.gitignore @@ -63,6 +63,9 @@ examples/tao-demo/src/main/native/windows/build_log.txt **/graalvm/libraryMetadata/ **/graalvm/metadataRepoDirs.txt +# Compiled Python caches (local helper scripts) +__pycache__/ + # JVM crash logs hs_err_pid*.log replay_pid*.log diff --git a/decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/ffi/NativeTaoWindowsDecoBridge.kt b/decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/ffi/NativeTaoWindowsDecoBridge.kt index d91ae1003..6bd639e06 100644 --- a/decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/ffi/NativeTaoWindowsDecoBridge.kt +++ b/decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/ffi/NativeTaoWindowsDecoBridge.kt @@ -306,4 +306,16 @@ internal object NativeTaoWindowsDecoBridge { startScreenX: Int, startScreenY: Int, ): LongArray?

Date: Tue, 1 Sep 2026 12:43:06 +0300 Subject: [PATCH 006/233] fix(tao): honour or reject Compose window v2 geometry requests MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit WindowState.requestSize()/requestPosition() build the two-arg WindowBoundsProvider, whose getBounds dereferences an AWT-backed WindowGeometryProviderScope. Tao has none, so the request was dropped — but the placement was already rewritten to Floating, knocking a maximized window out of maximized for a request that never applied. Skip the whole request when the provider cannot be evaluated, and log it at WARNING (rememberWindowStateWithBounds hits the same path). The observed bounds now fall back to the native window rectangle when the v1 position never turns Absolute: a WM that emits no move event for a PlatformDefault window left WindowState.isInitialized false and bounds / size / position throwing forever. Also: narrow the constantBoundsOrNull catch to NullPointerException so a provider's own failure is not reported as "needs live metrics"; move dialog size clamping out of composition into an effect; move inspectableWindowBounds to dev.nucleusframework.window.tao so apiCheck covers it and the split package with compose-ui is gone; document that setMinimumSize/setMaximumSize clear per window, not per axis; register ComposeWindowV2BridgeTest with the scene test battery drift guard. --- build.gradle.kts | 4 +- .../api/decorated-window-tao.api | 5 + .../ui/window/v2/ComposeWindowV2Access.java | 7 +- .../window/tao/ComposeWindowV2Bridge.kt | 192 ++++++++++++------ .../window/tao/DecoratedDialogV2.kt | 24 ++- .../window/tao/DecoratedWindowV2.kt | 26 ++- .../window/tao}/InspectableWindowBounds.kt | 15 +- .../nucleusframework/window/tao/TaoWindow.kt | 12 +- .../window/tao/ComposeWindowV2BridgeTest.kt | 30 ++- .../tao/TaoSceneTestBatteryDriftTest.kt | 2 + .../dev/nucleusframework/sampletao/Main.kt | 2 +- 11 files changed, 238 insertions(+), 81 deletions(-) rename decorated-window-tao/src/main/kotlin/{androidx/compose/ui/window/v2 => dev/nucleusframework/window/tao}/InspectableWindowBounds.kt (63%) diff --git a/build.gradle.kts b/build.gradle.kts index a97fdeac1..6572ed377 100644 --- a/build.gradle.kts +++ b/build.gradle.kts @@ -58,7 +58,9 @@ apiValidation { // access).

Observed bounds now always come from the native outer rect, and the request path converts back to the inner size the v1 state expects. Hosts that never expose the TaoWindow (rememberSyncedWindowState) left isInitialized false forever on a window manager that emits no initial move, making every bounds / size / position read throw. They now publish an approximate outer rect instead. The initial v2 -> v1 conversion drains the request channels, so a window that left and re-entered composition before ever being visible fell back to the 800x600 platform default. Memoize the drained geometry per state. constantBoundsOrNull treated any NullPointerException as "this provider needs AWT window metrics", hiding real provider bugs behind a dropped geometry request. Only the shapes that come from the null scope we pass in count now. requestSize / requestPosition stay inert: their providers live in a synthetic lambda's captures, so honouring them would need reflection, and building a WindowGeometryProviderScope would need a displayable AWT window.

Exception: `decorated-window-jewel` (JVM 25) is ignored by BCV until ASM supports class-file 69 — still uses `explicitApi()`.

Date: Tue, 1 Sep 2026 14:08:15 +0300 Subject: [PATCH 008/233] feat(tao): AWT-free clone of the Compose window API v2 MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Compose 1.12's `androidx.compose.ui.window.v2` is anchored to AWT: `Screen` wraps a `java.awt.GraphicsDevice` and reads its insets through `Toolkit.getDefaultToolkit()`, and `WindowGeometryProviderScope` takes a `java.awt.Window` that must already be displayable. The Tao backend has neither, so every provider that touches the scope was accepted, logged and dropped, and `requestScreen` was drained into the void. Mirror the package instead, member for member, as `dev.nucleusframework.window.tao.v2`, backed by our own monitor enumeration and `TaoWindow` rather than by AWT. Migrating is a single import change, and deleting the package restores the upstream import unchanged if JetBrains decouples its own types. - `TaoMonitors` / `TaoMonitor`: multi-monitor enumeration via a new `nativeGetMonitors` on each platform bridge (`EnumDisplayMonitors` + `GetDpiForMonitor` on Windows, `NSScreen.screens` on macOS, GDK monitors on Linux), one tab-separated descriptor per monitor. Physical pixels, top-left origin, work area included — the conventions the existing primary-monitor calls already used. Never reports zero monitors. - `v2`: `Screen`, `WindowScreenProvider(Scope)`, `WindowMetrics`, `WindowGeometryProviderScope`, `WindowBoundsProvider` / `WindowSizeProvider` / `WindowPositionProvider` with their companions, `WindowState`, `DialogState`, savers and `remember*` factories. - `DecoratedWindow` / `DecoratedDialog` / `HostedWindow` / `HostedDialog` / `NucleusWindowHost` overloads for the cloned states. The host default bodies fall back to the v1 surface, so themed hosts keep working; the default host overrides them for the full path. - Size and position stay split instead of folding into a `DpRect` (`CombinedBoundsProvider`): a rectangle cannot carry an unspecified position or a wrap-content axis without turning both into `NaN`. - Wrap-content sizing routes through the window's own path rather than a one-shot content measurement, so `Unconstrained` / `PreferredWidth` / `PreferredHeight` keep re-measuring. The Compose-typed overloads stay as they are — best effort with the warning — and their KDoc now points at the clone. Verified headfully on a real window (`taoHeadfulTest`, 5 new cases): initial provider centring, `requestSize` / `requestPosition`, a scoped bounds provider reading live window metrics, `requestScreen` landing on the target monitor, and `screenId` tracking the hosting monitor. --- CLAUDE.md | 1 + .../api/decorated-window-tao.api | 208 +++++++ .../window/tao/ComposeWindowV2Bridge.kt | 12 +- .../window/tao/DecoratedDialogV2.kt | 6 +- .../window/tao/DecoratedWindowNucleusV2.kt | 202 +++++++ .../window/tao/DecoratedWindowV2.kt | 17 +- .../window/tao/NucleusWindowV2Bridge.kt | 541 ++++++++++++++++++ .../window/tao/TaoMonitors.kt | 266 +++++++++ .../window/tao/ffi/NativeTaoBridge.kt | 11 + .../tao/ffi/NativeTaoMacOsDecoBridge.kt | 8 + .../tao/ffi/NativeTaoWindowsDecoBridge.kt | 9 + .../window/tao/v2/DialogState.kt | 254 ++++++++ .../nucleusframework/window/tao/v2/Screen.kt | 155 +++++ .../window/tao/v2/WindowGeometry.kt | 144 +++++ .../window/tao/v2/WindowProviders.kt | 312 ++++++++++ .../window/tao/v2/WindowState.kt | 374 ++++++++++++ .../src/main/native/macos/decoration.m | 63 ++ .../main/native/src/platform/linux/monitor.rs | 142 ++++- .../native/windows/nucleus_tao_windows_deco.c | 129 +++++ .../window/tao/NucleusWindowV2BridgeTest.kt | 268 +++++++++ .../window/tao/TaoMonitorsTest.kt | 92 +++ .../tao/TaoSceneTestBatteryDriftTest.kt | 4 + .../tao/headful/TaoHeadfulTestSuiteMain.kt | 109 ++-- .../tao/headful/TaoWindowTestHarness.kt | 7 + .../tao/headful/WindowApiV2HeadfulCases.kt | 247 ++++++++ .../api/nucleus-application.api | 12 + .../application/DecoratedDialog.kt | 88 +++ .../application/DecoratedWindow.kt | 132 +++++ .../application/NucleusWindowHost.kt | 287 ++++++++++ .../internal/TaoDecoratedDialogAdapter.kt | 46 ++ .../internal/TaoDecoratedWindowAdapter.kt | 62 ++ 31 files changed, 4151 insertions(+), 57 deletions(-) create mode 100644 decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/DecoratedWindowNucleusV2.kt create mode 100644 decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/NucleusWindowV2Bridge.kt create mode 100644 decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/TaoMonitors.kt create mode 100644 decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/v2/DialogState.kt create mode 100644 decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/v2/Screen.kt create mode 100644 decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/v2/WindowGeometry.kt create mode 100644 decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/v2/WindowProviders.kt create mode 100644 decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/v2/WindowState.kt create mode 100644 decorated-window-tao/src/test/kotlin/dev/nucleusframework/window/tao/NucleusWindowV2BridgeTest.kt create mode 100644 decorated-window-tao/src/test/kotlin/dev/nucleusframework/window/tao/TaoMonitorsTest.kt create mode 100644 decorated-window-tao/src/test/kotlin/dev/nucleusframework/window/tao/headful/WindowApiV2HeadfulCases.kt diff --git a/CLAUDE.md b/CLAUDE.md index f214326ae..0ed82921f 100644 --- a/CLAUDE.md +++ b/CLAUDE.md @@ -68,6 +68,7 @@ Published releases are `2.5.x` (latest tag `v2.5.0`).

Do not regenerate a baseline to silence a new finding; write the KDoc. `UndocumentedPublicProperty` stays off because the generated icon/symbol catalogs (`sf-symbols`, `freedesktop-icons`) would swamp it diff --git a/decorated-window-tao/api/decorated-window-tao.api b/decorated-window-tao/api/decorated-window-tao.api index 19a104a5c..4f1efabce 100644 --- a/decorated-window-tao/api/decorated-window-tao.api +++ b/decorated-window-tao/api/decorated-window-tao.api @@ -214,6 +214,11 @@ public final class dev/nucleusframework/window/tao/DecoratedWindowKt { public static final fun getLocalTaoWindow ()Landroidx/compose/runtime/ProvidableCompositionLocal;

Three mistakes, all verified this time against the gdk 0.18.2 sources: - `gtk::gdk::prelude::DisplayExt` does not exist — `Display`'s monitor accessors are inherent in gdk3-rs. This is the E0432 that failed the build. - `Monitor::is_primary()` does exist, so the primary flag no longer has to be matched on geometry — which would not have compiled either, since `gdk::Rectangle` implements no `PartialEq`. - `Rectangle` is a boxed inline type, so selecting between the geometry and the work area *by value* moved a rectangle still read afterwards. Read the four numbers out first and pick between tuples. Also spell the tab/newline sanitiser as two `replace` calls: the char-array `Pattern` impl is newer than the toolchain floor this crate builds with. --- .../main/native/src/platform/linux/monitor.rs | 50 ++++++++++--------- 1 file changed, 26 insertions(+), 24 deletions(-) diff --git a/decorated-window-tao/src/main/native/src/platform/linux/monitor.rs b/decorated-window-tao/src/main/native/src/platform/linux/monitor.rs index f418676f6..eb1c00083 100644 --- a/decorated-window-tao/src/main/native/src/platform/linux/monitor.rs +++ b/decorated-window-tao/src/main/native/src/platform/linux/monitor.rs @@ -109,12 +109,12 @@ pub extern "system" fn Java_dev_nucleusframework_window_tao_ffi_NativeTaoBridge_ } fn collect_monitors(handle: jlong) -> Option> { - use gtk::gdk::prelude::DisplayExt; + // `Display`'s monitor accessors are inherent in gdk3-rs (no DisplayExt); + // `Monitor`'s are on MonitorExt, like the primary-monitor helpers above. use gtk::prelude::MonitorExt; - let display = with_window(handle, |w| Some(display_of(w))) - .or_else(gtk::gdk::Display::default)?; - let primary = display.primary_monitor(); + let display = + with_window(handle, |w| Some(display_of(w))).or_else(gtk::gdk::Display::default)?; let count = display.n_monitors(); let mut rows = Vec::with_capacity(count.max(0) as usize); for index in 0..count { @@ -122,13 +122,20 @@ fn collect_monitors(handle: jlong) -> Option> { continue; }; let scale = monitor.scale_factor().max(1) as i64; + // Read the numbers out before picking: `Rectangle` is a boxed inline + // type, so selecting between the two rectangles by value would move + // `geometry` out from under the bounds array below. let geometry = monitor.geometry(); + let bounds = ( + geometry.x(), + geometry.y(), + geometry.width(), + geometry.height(), + ); let area = monitor.workarea(); - let work = if area.width() > 0 && area.height() > 0 { - area - } else { - geometry - }; + let area = (area.x(), area.y(), area.width(), area.height()); + // Some Wayland compositors report no work area. + let work = if area.2 > 0 && area.3 > 0 { area } else { bounds }; // GDK reports logical pixels on HiDPI; scale up to physical. let model = monitor.model().map(|s| s.to_string()).unwrap_or_default(); let manufacturer = monitor @@ -146,28 +153,23 @@ fn collect_monitors(handle: jlong) -> Option> { (mf, "") => mf.to_string(), (mf, m) => format!("{mf} {m}"), }; - // `Monitor` has no identity comparison in gdk3, so the primary flag is - // matched on geometry — two monitors cannot share an origin. - let is_primary = primary - .as_ref() - .map(|p| p.geometry() == geometry) - .unwrap_or(index == 0); + let is_primary = monitor.is_primary(); rows.push(encode_monitor( &id, &name, [ - geometry.x() as i64 * scale, - geometry.y() as i64 * scale, - geometry.width() as i64 * scale, - geometry.height() as i64 * scale, + bounds.0 as i64 * scale, + bounds.1 as i64 * scale, + bounds.2 as i64 * scale, + bounds.3 as i64 * scale, ], [ - work.x() as i64 * scale, - work.y() as i64 * scale, - work.width() as i64 * scale, - work.height() as i64 * scale, + work.0 as i64 * scale, + work.1 as i64 * scale, + work.2 as i64 * scale, + work.3 as i64 * scale, ], - (scale * 1000) as i64, + scale * 1000, is_primary, )); } From 06893f218cb53cc7fbd0d51c36520a8034aaff9e Mon Sep 17 00:00:00 2001 From: "Elie G."

The archetype comes from Flutter's multi-window + * design; this is the Tao implementation of the same contract: + * + * - **Anchored** — the initial position comes from a [WindowPositioner] + * ([SatelliteWindowState.positioner]) resolved against the parent's frame + * or a sub-rectangle of it, and kept inside the monitor work area. + * - **Follows its parent** — once placed, the satellite holds its offset from + * the parent's top-left corner: drag the parent and the satellite comes + * along. Drag the *satellite* and the new offset is what gets preserved. + * - **Above, but not modal** — it stays in front of its parent in z-order, + * keeps out of the taskbar / Dock / Alt-Tab, follows it across workspaces + * and minimisation, and leaves it fully interactive. + * - **Steps aside** — while the parent is fullscreen or maximized the + * satellite hides itself rather than covering content + * ([hideWhileParentFullscreenOrMaximized]). + * - **Dies with its parent** — closing the parent closes the satellite; + * [onCloseRequest] fires so the caller can drop it from composition. + * - **Reparentable** — pass a different [parent] and the satellite moves to + * the new owner without changing its position on screen, which is how a + * single palette can serve whichever document window is active. This holds + * even when the previous owner closes in the same frame: the satellite steps + * out of its owner link before the old window is destroyed, so the OS never + * takes it down with it. + * + * ```kotlin + * DecoratedWindow(onCloseRequest = ::exitApplication) { + * TitleBar { Text("Document") } + * Button({ palette = !palette }) { Text("Inspector") } + * if (palette) { + * SatelliteWindow( + * onCloseRequest = { palette = false }, + * state = rememberSatelliteWindowState( + * size = DpSize(260.dp, 420.dp), + * positioner = WindowPositioner( + * parentAnchor = WindowAnchor.TopRight, + * childAnchor = WindowAnchor.TopLeft, + * offset = DpOffset(12.dp, 0.dp), + * ), + * ), + * title = "Inspector", + * ) { + * Inspector() + * } + * } + * } + * ``` + * + * ### Platform notes + * Positioning a satellite requires the platform to let a client place its own + * windows. Native **Wayland** does not (xdg-shell gives the compositor full + * authority), so there the satellite is a plain owned window: correct z-order, + * ownership and lifetime, compositor-chosen placement, no follow. Run with + * `NUCLEUS_TAO_LINUX_RENDERER=x11`, or give the window `forceX11`, when the + * anchoring matters. X11, XWayland, Windows and macOS all follow. + * + * The work area the [WindowPositioner] keeps the satellite inside is the + * parent's own monitor on Windows. macOS and Linux fall back to the primary + * monitor's work area, so a parent on a secondary display whose Dock / panel + * layout differs may see its satellite flipped or slid against the wrong edge. + * + * @param onCloseRequest invoked when the user closes the satellite, and when + * its parent is destroyed. Drop the satellite from composition here. + * @param parent the window the satellite belongs to. Defaults to the enclosing + * [DecoratedWindow] via [LocalTaoWindow]; pass it explicitly to anchor to a + * window that isn't the one being composed.

Date: Wed, 2 Sep 2026 00:03:20 +0300 Subject: [PATCH 019/233] fix(launcher-linux): never autolaunch the session bus MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Nine of the last nine `preMerge` jobs that hit the 30-minute cap — on main as much as on feature branches, two of them running the full 6 hours before the cap existed — were stuck in `:launcher-linux:test`. The culprit is `g_bus_get_sync(G_BUS_TYPE_SESSION)` with `DBUS_SESSION_BUS_ADDRESS` unset: GDBus then autolaunches, spawning `dbus-launch --autolaunch`, which waits on an X display a headless process never provides. No timeout, so the JNI entry point never returns, and with `nativeRegisterQueryHandler` the calling thread also sits in a condvar wait for a worker thread that is itself stuck there.

Date: Wed, 2 Sep 2026 07:20:34 +0300 Subject: [PATCH 024/233] fix(tao): close the four documented gaps of the window v2 clone MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - `parentWindowMetrics` for dialogs: the `DecoratedDialog` overload captures its owner from `LocalTaoWindow` (the same capture the dialog uses for the native owner relationship) and hands it to the bridge, so `AlignedToParentWindow` resolves instead of reporting a missing parent. - Initial outer size: a v2 provider returns the outer rectangle, but before the window exists its insets are unknown, so it was applied as the inner size and a natively decorated frame came out larger by its chrome. Once mapped, the bridge measures the insets and — if the size is still the initial request — shrinks the inner size by them. - `measureWindowContent` is now a real measure pass: the scene host registers a per-window hook onto `ComposeScene.measureContent(constraints)` (`TaoContentMeasurers`, same shape as `WindowSizePolicy`) and the geometry scope calls it, converting through the window's scale. The clamped current size remains only for the pre-window / no-window cases. - X11 pre-map race: an absolute position applied before the window is mapped intermittently left it at GTK's unallocated 1×1 for good under Xvfb/openbox. The v1 Absolute path now waits for real outer bounds on Linux (≤1.5 s) before moving, the way Aligned already retries. The centring headful case runs on Linux again (size + containment; the WM still owns placement). --- .../window/tao/DecoratedWindowComposable.kt | 25 +++++++ .../window/tao/DecoratedWindowNucleusV2.kt | 5 +- .../window/tao/NucleusWindowV2Bridge.kt | 70 +++++++++++++++++-- .../window/tao/TaoContentMeasurers.kt | 30 ++++++++ .../window/tao/scene/TaoComposeSceneHost.kt | 9 +++ .../window/tao/v2/WindowGeometry.kt | 38 +++++++--- .../tao/headful/WindowApiV2HeadfulCases.kt | 21 ++---- 7 files changed, 167 insertions(+), 31 deletions(-) create mode 100644 decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/TaoContentMeasurers.kt diff --git a/decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/DecoratedWindowComposable.kt b/decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/DecoratedWindowComposable.kt index 3d6cd64cc..97afac4de 100644 --- a/decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/DecoratedWindowComposable.kt +++ b/decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/DecoratedWindowComposable.kt @@ -469,6 +469,12 @@ public fun ApplicationScope.DecoratedWindow( // outer origin so the ghost tracks the cursor instead of // landing up/left by the decoration inset + outer offset. val (xDp, yDp) = absolutePositionForPopup(window, pos) + // X11: a move issued before the window is mapped raced the map + // itself — under Xvfb/openbox the window intermittently stayed at + // GTK's unallocated 1×1 for good.

The e2e now measures under a finite maximum, which `fillMaxSize` must fill exactly. Six new headful cases probe the paths a single request never reaches: a burst of 40 position requests, size + position + screen in one tick, a bounds request on a maximized window, rapid maximize/restore toggling, requests from a background thread, and a frame-paced move animation. Two of them failed on the first run and found a real bug: `requestSize` immediately followed by `requestPosition` reverted the size. The second request's implicit `WindowSizeProvider.Current` read the *native* window, which had not applied the asynchronous resize yet — on AWT `setBounds` is synchronous so Compose can read the live window; on Tao `Current` has to mean the geometry already requested. The provider scope now builds its window rectangle from the pending v1 state on the axes it has (Absolute position, specified size) and from the native window on the others. --- .../window/tao/NucleusWindowV2Bridge.kt | 22 +- .../tao/scene/TaoComposeSceneHostLinux.kt | 9 + .../tao/scene/TaoComposeSceneHostWindows.kt | 9 + .../tao/headful/WindowApiV2HeadfulCases.kt | 222 +++++++++++++++++- 4 files changed, 253 insertions(+), 9 deletions(-) diff --git a/decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/NucleusWindowV2Bridge.kt b/decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/NucleusWindowV2Bridge.kt index 39d452110..b96ec0fba 100644 --- a/decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/NucleusWindowV2Bridge.kt +++ b/decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/NucleusWindowV2Bridge.kt @@ -425,9 +425,27 @@ private fun geometryScope( ): WindowGeometryProviderScope { val scale = TaoMonitors.referenceScale(window) val screen = Screen(TaoMonitors.forWindow(window), scale) + // `Current` must read the geometry already *requested*, not the native + // rectangle: applies are asynchronous, so two back-to-back requests — + // `requestSize` then `requestPosition`, whose implicit size is Current — + // would otherwise have the second one read the not-yet-resized window and + // revert the first.

The restore is asynchronous, and on macOS it is an animated un-zoom whose final frame lands *after* our size — putting the pre-zoom frame back over it. Two of the new headful edge cases (bounds while maximized, rapid maximize/restore toggling) timed out on the macOS runner for exactly that. Wait until the window reports neither maximized nor fullscreen (bounded, well past the zoom animation), then resolve the provider against the restored geometry and apply. --- .../window/tao/NucleusWindowV2Bridge.kt | 26 ++++++++++++++++++- 1 file changed, 25 insertions(+), 1 deletion(-) diff --git a/decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/NucleusWindowV2Bridge.kt b/decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/NucleusWindowV2Bridge.kt index b96ec0fba..0eb14a395 100644 --- a/decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/NucleusWindowV2Bridge.kt +++ b/decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/NucleusWindowV2Bridge.kt @@ -154,8 +154,17 @@ internal fun BindNucleusWindowState( } launch { for (provider in latestV2.boundsRequests) { + if (latestV1.placement != WindowPlacement.Floating) { + // Bounds on a non-floating window make it floating (the v2 + // contract) — but the restore is asynchronous, and on macOS + // an animated un-zoom whose final frame lands *after* our + // size would put the pre-zoom frame back over it.

The type test lives in `toTaoCursorIconCode()` only. The four scene hosts and the popup hosts each had their own hand-written copy of that mapping; they now delegate, so a new icon cannot reach three of them and silently fall back to the arrow in the fourth. Grab and grabbing are also added to the macOS table in `nucleus_tao_cursor_for_code` — a `TaoCursorIcon` code that is missing there resolves to the arrow, whatever the Rust side maps it to. --- .../window/tao/TaoEventConstants.kt | 6 ++ .../window/tao/TaoPointerIcons.kt | 56 +++++++++++++++++++ .../window/tao/event/TaoCursorMapping.kt | 4 ++ .../tao/popup/TaoStandalonePopupHost.kt | 26 +-------- .../window/tao/scene/TaoComposeSceneHost.kt | 26 +-------- .../tao/scene/TaoComposeSceneHostLinux.kt | 33 +---------- .../tao/scene/TaoComposeSceneHostWindows.kt | 33 +---------- .../main/native/macos/main_thread_dispatch.m | 2 + .../src/main/native/src/cursor.rs | 7 ++- 9 files changed, 81 insertions(+), 112 deletions(-) create mode 100644 decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/TaoPointerIcons.kt diff --git a/decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/TaoEventConstants.kt b/decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/TaoEventConstants.kt index a480f8f03..681402c95 100644 --- a/decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/TaoEventConstants.kt +++ b/decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/TaoEventConstants.kt @@ -18,6 +18,12 @@ public object TaoCursorIcon { public const val NS_RESIZE: Int = 10 public const val NESW_RESIZE: Int = 11 public const val NWSE_RESIZE: Int = 12 + + /** Open hand: this can be picked up and dragged. */ + public const val GRAB: Int = 13 + + /** Closed hand: it is being dragged. */ + public const val GRABBING: Int = 14 } /** Mirrors the event constants in `nucleus_tao` (`lib.rs`). */ diff --git a/decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/TaoPointerIcons.kt b/decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/TaoPointerIcons.kt new file mode 100644 index 000000000..50fa3be28 --- /dev/null +++ b/decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/TaoPointerIcons.kt @@ -0,0 +1,56 @@ +package dev.nucleusframework.window.tao + +import androidx.compose.ui.input.pointer.PointerIcon + +/** + * A [PointerIcon] backed by a native Tao cursor, recognised by the Tao scene + * hosts and passed straight to `Window::set_cursor_icon`. + */ +internal class TaoPointerIcon( + val code: Int, +) : PointerIcon + +/** + * Pointer icons beyond the four Compose defines in common code + * (`Default`, `Text`, `Hand`, `Crosshair`). + * + * Use them with `Modifier.pointerHoverIcon` like any other icon: + * + * ```kotlin + * Modifier.pointerHoverIcon(TaoPointerIcons.Grab) + * ``` + * + * They resolve to the platform's own shapes (AppKit `openHandCursor` / + * `closedHandCursor`, the freedesktop `grab` / `grabbing` themed cursors, the + * Win32 equivalents), and fall back to the arrow where a platform has none. + * Compose Desktop's AWT-based `PointerIcon(Cursor(…))` is not usable on this + * backend — the process runs without AWT. + */ +public object TaoPointerIcons { + /** Open hand: this element can be picked up.

That covers a palette attached to a document; it does not cover the workspace a real tool app has, where one palette serves whichever document is in front and can be pulled into the document itself. `SatelliteWorkspace` owns that. Windows join it, satellites are declared against it once at application scope, and it decides who hosts what: - the owner of the floating satellites follows keyboard focus between members, or is pinned with `pinTo`; when it closes, the next member takes over and the satellites move on without shifting on screen; - `SatellitePlacement.Floating` / `Docked(side)` chooses between an owned window and a panel inside the owner's `DockLayout`, with a splitter per side and several panels per side ordered by `order`; - `Modifier.satelliteDragHandle` — installed on the default header — drags a satellite between the two. The four dock zones of every member light up as the pointer enters the window, and a panel dragged out is previewed by a borderless click-through ghost window that follows the pointer out of the host, then lands where it was dropped; - `snapshot()` / `restore()` hand the whole layout to the app to persist. `rememberSaveable` state inside a satellite survives the move between hosts. The keys are composite key hashes of the call site, so they differ between the two compositions; `RelocatingSaveableStateRegistry` maps them across by the one property that relation has — the hashes differ by a rotation of the XOR of the two host anchors — and keeps values in registration order, which is what a key shared by several call sites depends on. Also fixed here, both found while testing the above: - a satellite that opts out of hiding could end up *behind* its owner after a maximize or a fullscreen transition, because nothing re-asserted the native owner link once the owner had been re-stacked; - a drag whose gesture was interrupted rather than finished — the host resized under it, re-keying its pointer input — left the zone hints and the ghost on screen for good. Sessions are now tracked, a superseded one is inert, and pointer samples that are not finite are dropped instead of reaching window geometry. `DockLayout` composes the document from a single stable slot: side stacks and splitters are always emitted and return early when empty, so docking a first panel cannot move the content's subtree and reset its scroll position. Covered by 28 unit cases (ownership, docking, snapshots, key relocation, and the adversarial half: teleporting pointers, NaN samples, superseded and double-ended sessions, hosts leaving mid-drag, churn) and 20 headful cases on real windows, including two driven by a real mouse through the AWT Robot. --- CLAUDE.md | 2 +- .../api/decorated-window-tao.api | 243 +++++ .../nucleusframework/window/tao/DockLayout.kt | 341 +++++++ .../nucleusframework/window/tao/Satellite.kt | 634 ++++++++++++ .../window/tao/SatellitePlacement.kt | 81 ++ .../window/tao/SatelliteWindow.kt | 55 +- .../window/tao/SatelliteWorkspace.kt | 919 ++++++++++++++++++ .../window/tao/TaoApplication.kt | 3 + .../nucleusframework/window/tao/TaoWindow.kt | 24 +- .../window/tao/SatelliteWorkspaceTest.kt | 749 ++++++++++++++ .../window/tao/TaoSceneTestBattery.kt | 94 ++ .../tao/TaoSceneTestBatteryDriftTest.kt | 1 + .../headful/SatelliteWindowHeadfulCases.kt | 142 +++ .../tao/headful/SatelliteWorkspaceFixture.kt | 299 ++++++ .../headful/SatelliteWorkspaceHeadfulCases.kt | 491 ++++++++++ .../SatelliteWorkspaceStressHeadfulCases.kt | 383 ++++++++ .../tao/headful/TaoHeadfulTestSuiteMain.kt | 5 + .../tao/headful/TaoWindowTestHarness.kt | 16 + examples/satellite-demo/build.gradle.kts | 8 +- .../satellitedemo/DemoState.kt | 94 +- .../satellitedemo/DocumentContent.kt | 162 ++- .../satellitedemo/InspectorContent.kt | 83 +- .../nucleusframework/satellitedemo/Main.kt | 143 +-- .../satellitedemo/ToolsContent.kt | 63 ++ .../api/nucleus-application.api | 13 + .../nucleusframework/application/Satellite.kt | 114 +++ .../internal/TaoSatelliteWindowAdapter.kt | 78 +- .../internal/TaoSatelliteWorkspaceAdapter.kt | 55 ++ 28 files changed, 5084 insertions(+), 211 deletions(-) create mode 100644 decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/DockLayout.kt create mode 100644 decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/Satellite.kt create mode 100644 decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/SatellitePlacement.kt create mode 100644 decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/SatelliteWorkspace.kt create mode 100644 decorated-window-tao/src/test/kotlin/dev/nucleusframework/window/tao/SatelliteWorkspaceTest.kt create mode 100644 decorated-window-tao/src/test/kotlin/dev/nucleusframework/window/tao/headful/SatelliteWorkspaceFixture.kt create mode 100644 decorated-window-tao/src/test/kotlin/dev/nucleusframework/window/tao/headful/SatelliteWorkspaceHeadfulCases.kt create mode 100644 decorated-window-tao/src/test/kotlin/dev/nucleusframework/window/tao/headful/SatelliteWorkspaceStressHeadfulCases.kt create mode 100644 examples/satellite-demo/src/main/kotlin/dev/nucleusframework/satellitedemo/ToolsContent.kt create mode 100644 nucleus-application/src/main/kotlin/dev/nucleusframework/application/Satellite.kt create mode 100644 nucleus-application/src/main/kotlin/dev/nucleusframework/application/internal/TaoSatelliteWorkspaceAdapter.kt diff --git a/CLAUDE.md b/CLAUDE.md index a34171975..04a67cb7f 100644 --- a/CLAUDE.md +++ b/CLAUDE.md @@ -42,7 +42,7 @@ Published releases are `2.5.x` (latest tag `v2.5.0`).

Two of the headful edge cases were intermittent on the macOS runner for that reason.

Extract it, then use it. `window/tao/workspace/` is the shared internal core: - `WindowGroup`: membership, focus recency and pinning, with the owner derived from them. `membersByRecency` gives overlapping drop targets a real tie-break instead of registration order. - `RelocatedContentHost` / `RelocatingSaveableStateRegistry` / `RelocatableSlot`: content that keeps its saveable state when it changes window, keys relocated by the rotation of the anchor XOR. - `HostGeometry` / `HostGeometryRegistry`: a drop target's rect on screen, plus `Modifier.publishHostGeometry`. A minimized host is filtered out — its frame is on record, but nothing of it is on screen to drop onto. - `DragController` and `Modifier.screenDragHandle`: one live drag, superseded sessions inert, cleanup on a gesture that is interrupted rather than finished. - `DragGhostWindow`: the borderless click-through preview. `SatelliteWorkspace` and `Satellite` now compose that core instead of carrying their own copy; behaviour is unchanged and the whole existing suite still passes. `SatelliteDragSession` becomes an interface — the sealed class exposed `isLive` in the ABI. On top of it, `TabWorkspace`: the Chrome tab model. Tabs are declared once with `Tab`, `TabWindows` composes one `DecoratedWindow` per group, and windows follow the tabs — a tear-off adds one, the last tab out closes one. `TabStrip` publishes its slots so a drag resolves to an insertion index; dragging one of several tabs lifts it under a ghost, dragging the only tab of a window moves the window and merges it into whatever strip it lands on. Three things the real-window suite found: - a change of selection handed the arriving body the composition slots of the one that left — its `remember`, its effects and its `rememberSaveable` entries. Two tabs shared state. The body is now keyed on the tab, above the relocation anchor; - a tab torn out of a maximized window inherited the maximized frame, so the user got a second screen-sized window. It gets the workspace default instead; - `TabWindowGroup.ids` returned the live `SnapshotStateList`, which compares by identity when it is the receiver of `==`. It returns a snapshot. Covered by 57 unit cases (the core's own 19, plus 38 for the tab model: placement, selection, moves, tear-off, drop resolution, and the adversarial half — teleporting pointers, non-finite samples, superseded and double-ended sessions, a window or a tab vanishing mid-gesture, churn) and 12 headful cases on real windows: the tear-off / merge / close lifecycle with a real mouse, state across windows, snapshots, abrupt pointer jumps, a robot flick, a backing-scale change, minimize, maximize, and interrupted or superseded drags. --- CLAUDE.md | 1 + .../api/decorated-window-tao.api | 179 +++- .../nucleusframework/window/tao/DockLayout.kt | 23 +- .../nucleusframework/window/tao/Satellite.kt | 359 ++------ .../window/tao/SatelliteDragSessions.kt | 119 +++ .../window/tao/SatelliteWorkspace.kt | 372 ++------- .../window/tao/TabDragSessions.kt | 160 ++++ .../nucleusframework/window/tao/TabStrip.kt | 302 +++++++ .../nucleusframework/window/tao/TabWindows.kt | 243 ++++++ .../window/tao/TabWorkspace.kt | 651 +++++++++++++++ .../window/tao/workspace/CrossWindowDrag.kt | 165 ++++ .../window/tao/workspace/DragGhostWindow.kt | 67 ++ .../window/tao/workspace/HostGeometry.kt | 135 +++ .../tao/workspace/RelocatableContent.kt | 199 +++++ .../window/tao/workspace/WindowGroup.kt | 115 +++ .../window/tao/SatelliteWorkspaceTest.kt | 143 ++-- .../window/tao/TabWorkspaceTest.kt | 785 ++++++++++++++++++ .../window/tao/TaoSceneTestBattery.kt | 197 ++++- .../tao/TaoSceneTestBatteryDriftTest.kt | 9 + .../window/tao/headful/TabWorkspaceFixture.kt | 227 +++++ .../tao/headful/TabWorkspaceHeadfulCases.kt | 363 ++++++++ .../headful/TabWorkspaceStressHeadfulCases.kt | 565 +++++++++++++ .../tao/headful/TaoHeadfulTestSuiteMain.kt | 2 + .../tao/workspace/DragControllerTest.kt | 63 ++ .../window/tao/workspace/HostGeometryTest.kt | 81 ++ .../RelocatingSaveableStateRegistryTest.kt | 108 +++ .../window/tao/workspace/WindowGroupTest.kt | 127 +++ 27 files changed, 5065 insertions(+), 695 deletions(-) create mode 100644 decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/SatelliteDragSessions.kt create mode 100644 decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/TabDragSessions.kt create mode 100644 decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/TabStrip.kt create mode 100644 decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/TabWindows.kt create mode 100644 decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/TabWorkspace.kt create mode 100644 decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/workspace/CrossWindowDrag.kt create mode 100644 decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/workspace/DragGhostWindow.kt create mode 100644 decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/workspace/HostGeometry.kt create mode 100644 decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/workspace/RelocatableContent.kt create mode 100644 decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/workspace/WindowGroup.kt create mode 100644 decorated-window-tao/src/test/kotlin/dev/nucleusframework/window/tao/TabWorkspaceTest.kt create mode 100644 decorated-window-tao/src/test/kotlin/dev/nucleusframework/window/tao/headful/TabWorkspaceFixture.kt create mode 100644 decorated-window-tao/src/test/kotlin/dev/nucleusframework/window/tao/headful/TabWorkspaceHeadfulCases.kt create mode 100644 decorated-window-tao/src/test/kotlin/dev/nucleusframework/window/tao/headful/TabWorkspaceStressHeadfulCases.kt create mode 100644 decorated-window-tao/src/test/kotlin/dev/nucleusframework/window/tao/workspace/DragControllerTest.kt create mode 100644 decorated-window-tao/src/test/kotlin/dev/nucleusframework/window/tao/workspace/HostGeometryTest.kt create mode 100644 decorated-window-tao/src/test/kotlin/dev/nucleusframework/window/tao/workspace/RelocatingSaveableStateRegistryTest.kt create mode 100644 decorated-window-tao/src/test/kotlin/dev/nucleusframework/window/tao/workspace/WindowGroupTest.kt diff --git a/CLAUDE.md b/CLAUDE.md index 04a67cb7f..febe66bca 100644 --- a/CLAUDE.md +++ b/CLAUDE.md @@ -37,6 +37,7 @@ Published releases are `2.5.x` (latest tag `v2.5.0`).

TaoWindow gains what a window that observes *another* window needs: setOuterPositionPx (physical-pixel positioning, SetWindowPos on Windows so a second-monitor DPI never leaks in), remove*Listener counterparts for the multi-cast moved / resized / destroyed / fullscreen-prepare hooks, and an onClosing hook fired at the start of requestClose() so owned windows can sever their owner link before the OS would take them down with it. --- .../window/tao/DecoratedDialog.kt | 116 ++++++++++++------ .../nucleusframework/window/tao/TaoWindow.kt | 75 +++++++++++ 2 files changed, 152 insertions(+), 39 deletions(-) diff --git a/decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/DecoratedDialog.kt b/decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/DecoratedDialog.kt index 5a77b3fc5..98a76cafd 100644 --- a/decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/DecoratedDialog.kt +++ b/decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/DecoratedDialog.kt @@ -157,9 +157,9 @@ public fun ApplicationScope.DecoratedDialog( // without an owner never receives a configure, so setContent // never runs and wrap-content deadlocks (#532).

The archetype comes from Flutter's multi-window + * design; this is the Tao implementation of the same contract: + * + * - **Anchored** — the initial position comes from a [WindowPositioner] + * ([SatelliteWindowState.positioner]) resolved against the parent's frame + * or a sub-rectangle of it, and kept inside the monitor work area. + * - **Follows its parent** — once placed, the satellite holds its offset from + * the parent's top-left corner: drag the parent and the satellite comes + * along. Drag the *satellite* and the new offset is what gets preserved. + * - **Above, but not modal** — it stays in front of its parent in z-order, + * keeps out of the taskbar / Dock / Alt-Tab, follows it across workspaces + * and minimisation, and leaves it fully interactive. + * - **Steps aside** — while the parent is fullscreen or maximized the + * satellite hides itself rather than covering content + * ([hideWhileParentFullscreenOrMaximized]). + * - **Dies with its parent** — closing the parent closes the satellite; + * [onCloseRequest] fires so the caller can drop it from composition. + * - **Reparentable** — pass a different [parent] and the satellite moves to + * the new owner without changing its position on screen, which is how a + * single palette can serve whichever document window is active. This holds + * even when the previous owner closes in the same frame: the satellite steps + * out of its owner link before the old window is destroyed, so the OS never + * takes it down with it. + * + * ```kotlin + * DecoratedWindow(onCloseRequest = ::exitApplication) { + * TitleBar { Text("Document") } + * Button({ palette = !palette }) { Text("Inspector") } + * if (palette) { + * SatelliteWindow( + * onCloseRequest = { palette = false }, + * state = rememberSatelliteWindowState( + * size = DpSize(260.dp, 420.dp), + * positioner = WindowPositioner( + * parentAnchor = WindowAnchor.TopRight, + * childAnchor = WindowAnchor.TopLeft, + * offset = DpOffset(12.dp, 0.dp), + * ), + * ), + * title = "Inspector", + * ) { + * Inspector() + * } + * } + * } + * ``` + * + * ### Platform notes + * Positioning a satellite requires the platform to let a client place its own + * windows.

X11, XWayland, Windows and macOS all follow. + * + * The work area the [WindowPositioner] keeps the satellite inside is the + * parent's own monitor on Windows. macOS and Linux fall back to the primary + * monitor's work area, so a parent on a secondary display whose Dock / panel + * layout differs may see its satellite flipped or slid against the wrong edge. + * + * @param onCloseRequest invoked when the user closes the satellite, and when + * its parent is destroyed.

The type test lives in `toTaoCursorIconCode()` only. The four scene hosts and the popup hosts each had their own hand-written copy of that mapping; they now delegate, so a new icon cannot reach three of them and silently fall back to the arrow in the fourth. Grab and grabbing are also added to the macOS table in `nucleus_tao_cursor_for_code` — a `TaoCursorIcon` code that is missing there resolves to the arrow, whatever the Rust side maps it to. --- .../window/tao/TaoEventConstants.kt | 6 ++ .../window/tao/TaoPointerIcons.kt | 56 +++++++++++++++++++ .../window/tao/event/TaoCursorMapping.kt | 4 ++ .../tao/popup/TaoStandalonePopupHost.kt | 26 +-------- .../window/tao/scene/TaoComposeSceneHost.kt | 26 +-------- .../tao/scene/TaoComposeSceneHostLinux.kt | 33 +---------- .../tao/scene/TaoComposeSceneHostWindows.kt | 33 +---------- .../main/native/macos/main_thread_dispatch.m | 2 + .../src/main/native/src/cursor.rs | 7 ++- 9 files changed, 81 insertions(+), 112 deletions(-) create mode 100644 decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/TaoPointerIcons.kt diff --git a/decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/TaoEventConstants.kt b/decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/TaoEventConstants.kt index a480f8f03..681402c95 100644 --- a/decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/TaoEventConstants.kt +++ b/decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/TaoEventConstants.kt @@ -18,6 +18,12 @@ public object TaoCursorIcon { public const val NS_RESIZE: Int = 10 public const val NESW_RESIZE: Int = 11 public const val NWSE_RESIZE: Int = 12 + + /** Open hand: this can be picked up and dragged. */ + public const val GRAB: Int = 13 + + /** Closed hand: it is being dragged. */ + public const val GRABBING: Int = 14 } /** Mirrors the event constants in `nucleus_tao` (`lib.rs`). */ diff --git a/decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/TaoPointerIcons.kt b/decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/TaoPointerIcons.kt new file mode 100644 index 000000000..50fa3be28 --- /dev/null +++ b/decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/TaoPointerIcons.kt @@ -0,0 +1,56 @@ +package dev.nucleusframework.window.tao + +import androidx.compose.ui.input.pointer.PointerIcon + +/** + * A [PointerIcon] backed by a native Tao cursor, recognised by the Tao scene + * hosts and passed straight to `Window::set_cursor_icon`. + */ +internal class TaoPointerIcon( + val code: Int, +) : PointerIcon + +/** + * Pointer icons beyond the four Compose defines in common code + * (`Default`, `Text`, `Hand`, `Crosshair`). + * + * Use them with `Modifier.pointerHoverIcon` like any other icon: + * + * ```kotlin + * Modifier.pointerHoverIcon(TaoPointerIcons.Grab) + * ``` + * + * They resolve to the platform's own shapes (AppKit `openHandCursor` / + * `closedHandCursor`, the freedesktop `grab` / `grabbing` themed cursors, the + * Win32 equivalents), and fall back to the arrow where a platform has none. + * Compose Desktop's AWT-based `PointerIcon(Cursor(…))` is not usable on this + * backend — the process runs without AWT. + */ +public object TaoPointerIcons { + /** Open hand: this element can be picked up.

That covers a palette attached to a document; it does not cover the workspace a real tool app has, where one palette serves whichever document is in front and can be pulled into the document itself. `SatelliteWorkspace` owns that. Windows join it, satellites are declared against it once at application scope, and it decides who hosts what: - the owner of the floating satellites follows keyboard focus between members, or is pinned with `pinTo`; when it closes, the next member takes over and the satellites move on without shifting on screen; - `SatellitePlacement.Floating` / `Docked(side)` chooses between an owned window and a panel inside the owner's `DockLayout`, with a splitter per side and several panels per side ordered by `order`; - `Modifier.satelliteDragHandle` — installed on the default header — drags a satellite between the two. The four dock zones of every member light up as the pointer enters the window, and a panel dragged out is previewed by a borderless click-through ghost window that follows the pointer out of the host, then lands where it was dropped; - `snapshot()` / `restore()` hand the whole layout to the app to persist. `rememberSaveable` state inside a satellite survives the move between hosts. The keys are composite key hashes of the call site, so they differ between the two compositions; `RelocatingSaveableStateRegistry` maps them across by the one property that relation has — the hashes differ by a rotation of the XOR of the two host anchors — and keeps values in registration order, which is what a key shared by several call sites depends on. Also fixed here, both found while testing the above: - a satellite that opts out of hiding could end up *behind* its owner after a maximize or a fullscreen transition, because nothing re-asserted the native owner link once the owner had been re-stacked; - a drag whose gesture was interrupted rather than finished — the host resized under it, re-keying its pointer input — left the zone hints and the ghost on screen for good. Sessions are now tracked, a superseded one is inert, and pointer samples that are not finite are dropped instead of reaching window geometry. `DockLayout` composes the document from a single stable slot: side stacks and splitters are always emitted and return early when empty, so docking a first panel cannot move the content's subtree and reset its scroll position. Covered by 28 unit cases (ownership, docking, snapshots, key relocation, and the adversarial half: teleporting pointers, NaN samples, superseded and double-ended sessions, hosts leaving mid-drag, churn) and 20 headful cases on real windows, including two driven by a real mouse through the AWT Robot. --- CLAUDE.md | 2 +- .../api/decorated-window-tao.api | 243 +++++ .../nucleusframework/window/tao/DockLayout.kt | 341 +++++++ .../nucleusframework/window/tao/Satellite.kt | 634 ++++++++++++ .../window/tao/SatellitePlacement.kt | 81 ++ .../window/tao/SatelliteWindow.kt | 55 +- .../window/tao/SatelliteWorkspace.kt | 919 ++++++++++++++++++ .../window/tao/TaoApplication.kt | 3 + .../nucleusframework/window/tao/TaoWindow.kt | 24 +- .../window/tao/SatelliteWorkspaceTest.kt | 749 ++++++++++++++ .../window/tao/TaoSceneTestBattery.kt | 94 ++ .../tao/TaoSceneTestBatteryDriftTest.kt | 1 + .../headful/SatelliteWindowHeadfulCases.kt | 142 +++ .../tao/headful/SatelliteWorkspaceFixture.kt | 299 ++++++ .../headful/SatelliteWorkspaceHeadfulCases.kt | 491 ++++++++++ .../SatelliteWorkspaceStressHeadfulCases.kt | 383 ++++++++ .../tao/headful/TaoHeadfulTestSuiteMain.kt | 5 + .../tao/headful/TaoWindowTestHarness.kt | 16 + examples/satellite-demo/build.gradle.kts | 8 +- .../satellitedemo/DemoState.kt | 94 +- .../satellitedemo/DocumentContent.kt | 162 ++- .../satellitedemo/InspectorContent.kt | 83 +- .../nucleusframework/satellitedemo/Main.kt | 143 +-- .../satellitedemo/ToolsContent.kt | 63 ++ .../api/nucleus-application.api | 13 + .../nucleusframework/application/Satellite.kt | 114 +++ .../internal/TaoSatelliteWindowAdapter.kt | 78 +- .../internal/TaoSatelliteWorkspaceAdapter.kt | 55 ++ 28 files changed, 5084 insertions(+), 211 deletions(-) create mode 100644 decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/DockLayout.kt create mode 100644 decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/Satellite.kt create mode 100644 decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/SatellitePlacement.kt create mode 100644 decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/SatelliteWorkspace.kt create mode 100644 decorated-window-tao/src/test/kotlin/dev/nucleusframework/window/tao/SatelliteWorkspaceTest.kt create mode 100644 decorated-window-tao/src/test/kotlin/dev/nucleusframework/window/tao/headful/SatelliteWorkspaceFixture.kt create mode 100644 decorated-window-tao/src/test/kotlin/dev/nucleusframework/window/tao/headful/SatelliteWorkspaceHeadfulCases.kt create mode 100644 decorated-window-tao/src/test/kotlin/dev/nucleusframework/window/tao/headful/SatelliteWorkspaceStressHeadfulCases.kt create mode 100644 examples/satellite-demo/src/main/kotlin/dev/nucleusframework/satellitedemo/ToolsContent.kt create mode 100644 nucleus-application/src/main/kotlin/dev/nucleusframework/application/Satellite.kt create mode 100644 nucleus-application/src/main/kotlin/dev/nucleusframework/application/internal/TaoSatelliteWorkspaceAdapter.kt diff --git a/CLAUDE.md b/CLAUDE.md index 3ee1f69f9..c62a25e7e 100644 --- a/CLAUDE.md +++ b/CLAUDE.md @@ -42,7 +42,7 @@ Published releases are `2.5.x` (latest tag `v2.5.0`).

Extract it, then use it. `window/tao/workspace/` is the shared internal core: - `WindowGroup`: membership, focus recency and pinning, with the owner derived from them. `membersByRecency` gives overlapping drop targets a real tie-break instead of registration order. - `RelocatedContentHost` / `RelocatingSaveableStateRegistry` / `RelocatableSlot`: content that keeps its saveable state when it changes window, keys relocated by the rotation of the anchor XOR. - `HostGeometry` / `HostGeometryRegistry`: a drop target's rect on screen, plus `Modifier.publishHostGeometry`. A minimized host is filtered out — its frame is on record, but nothing of it is on screen to drop onto. - `DragController` and `Modifier.screenDragHandle`: one live drag, superseded sessions inert, cleanup on a gesture that is interrupted rather than finished. - `DragGhostWindow`: the borderless click-through preview. `SatelliteWorkspace` and `Satellite` now compose that core instead of carrying their own copy; behaviour is unchanged and the whole existing suite still passes. `SatelliteDragSession` becomes an interface — the sealed class exposed `isLive` in the ABI. On top of it, `TabWorkspace`: the Chrome tab model. Tabs are declared once with `Tab`, `TabWindows` composes one `DecoratedWindow` per group, and windows follow the tabs — a tear-off adds one, the last tab out closes one. `TabStrip` publishes its slots so a drag resolves to an insertion index; dragging one of several tabs lifts it under a ghost, dragging the only tab of a window moves the window and merges it into whatever strip it lands on. Three things the real-window suite found: - a change of selection handed the arriving body the composition slots of the one that left — its `remember`, its effects and its `rememberSaveable` entries. Two tabs shared state. The body is now keyed on the tab, above the relocation anchor; - a tab torn out of a maximized window inherited the maximized frame, so the user got a second screen-sized window. It gets the workspace default instead; - `TabWindowGroup.ids` returned the live `SnapshotStateList`, which compares by identity when it is the receiver of `==`. It returns a snapshot. Covered by 57 unit cases (the core's own 19, plus 38 for the tab model: placement, selection, moves, tear-off, drop resolution, and the adversarial half — teleporting pointers, non-finite samples, superseded and double-ended sessions, a window or a tab vanishing mid-gesture, churn) and 12 headful cases on real windows: the tear-off / merge / close lifecycle with a real mouse, state across windows, snapshots, abrupt pointer jumps, a robot flick, a backing-scale change, minimize, maximize, and interrupted or superseded drags. --- CLAUDE.md | 1 + .../api/decorated-window-tao.api | 179 +++- .../nucleusframework/window/tao/DockLayout.kt | 23 +- .../nucleusframework/window/tao/Satellite.kt | 359 ++------ .../window/tao/SatelliteDragSessions.kt | 119 +++ .../window/tao/SatelliteWorkspace.kt | 372 ++------- .../window/tao/TabDragSessions.kt | 160 ++++ .../nucleusframework/window/tao/TabStrip.kt | 302 +++++++ .../nucleusframework/window/tao/TabWindows.kt | 243 ++++++ .../window/tao/TabWorkspace.kt | 651 +++++++++++++++ .../window/tao/workspace/CrossWindowDrag.kt | 165 ++++ .../window/tao/workspace/DragGhostWindow.kt | 67 ++ .../window/tao/workspace/HostGeometry.kt | 135 +++ .../tao/workspace/RelocatableContent.kt | 199 +++++ .../window/tao/workspace/WindowGroup.kt | 115 +++ .../window/tao/SatelliteWorkspaceTest.kt | 143 ++-- .../window/tao/TabWorkspaceTest.kt | 785 ++++++++++++++++++ .../window/tao/TaoSceneTestBattery.kt | 197 ++++- .../tao/TaoSceneTestBatteryDriftTest.kt | 9 + .../window/tao/headful/TabWorkspaceFixture.kt | 227 +++++ .../tao/headful/TabWorkspaceHeadfulCases.kt | 363 ++++++++ .../headful/TabWorkspaceStressHeadfulCases.kt | 565 +++++++++++++ .../tao/headful/TaoHeadfulTestSuiteMain.kt | 4 +- .../tao/workspace/DragControllerTest.kt | 63 ++ .../window/tao/workspace/HostGeometryTest.kt | 81 ++ .../RelocatingSaveableStateRegistryTest.kt | 108 +++ .../window/tao/workspace/WindowGroupTest.kt | 127 +++ 27 files changed, 5066 insertions(+), 696 deletions(-) create mode 100644 decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/SatelliteDragSessions.kt create mode 100644 decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/TabDragSessions.kt create mode 100644 decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/TabStrip.kt create mode 100644 decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/TabWindows.kt create mode 100644 decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/TabWorkspace.kt create mode 100644 decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/workspace/CrossWindowDrag.kt create mode 100644 decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/workspace/DragGhostWindow.kt create mode 100644 decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/workspace/HostGeometry.kt create mode 100644 decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/workspace/RelocatableContent.kt create mode 100644 decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/workspace/WindowGroup.kt create mode 100644 decorated-window-tao/src/test/kotlin/dev/nucleusframework/window/tao/TabWorkspaceTest.kt create mode 100644 decorated-window-tao/src/test/kotlin/dev/nucleusframework/window/tao/headful/TabWorkspaceFixture.kt create mode 100644 decorated-window-tao/src/test/kotlin/dev/nucleusframework/window/tao/headful/TabWorkspaceHeadfulCases.kt create mode 100644 decorated-window-tao/src/test/kotlin/dev/nucleusframework/window/tao/headful/TabWorkspaceStressHeadfulCases.kt create mode 100644 decorated-window-tao/src/test/kotlin/dev/nucleusframework/window/tao/workspace/DragControllerTest.kt create mode 100644 decorated-window-tao/src/test/kotlin/dev/nucleusframework/window/tao/workspace/HostGeometryTest.kt create mode 100644 decorated-window-tao/src/test/kotlin/dev/nucleusframework/window/tao/workspace/RelocatingSaveableStateRegistryTest.kt create mode 100644 decorated-window-tao/src/test/kotlin/dev/nucleusframework/window/tao/workspace/WindowGroupTest.kt diff --git a/CLAUDE.md b/CLAUDE.md index c62a25e7e..b0418c57d 100644 --- a/CLAUDE.md +++ b/CLAUDE.md @@ -37,6 +37,7 @@ Published releases are `2.5.x` (latest tag `v2.5.0`).

anywhere on its title bar MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The header strip centres itself in the title bar, so the few dp above and below it belonged to `windowDragArea` — the platform's own interactive move. That move is a compositor grab: it swallows every pointer event up to and including the release, so a satellite grabbed there could be moved but never docked. Grabbing the strip docked, three pixels higher did nothing. For a palette that is the wrong trade: the window is small, it is grabbed by its bar, and docking is the point. `BasicTitleBar` gains `nativeWindowDrag`, on by default so nothing else changes. A window that moves itself during the gesture turns it off and supplies its own drag through `modifier`, which lands on the bar root and therefore covers the whole bar rather than the part the content happens to occupy. `Satellite` does exactly that, and gives up OS snapping for its palettes in exchange. `DefaultSatelliteHeader` now carries the handle only while docked: the floating bar already is one, and nesting two would start two drags for one gesture. Tab windows keep the browser split — a tab drags, the empty strip area is a platform move with its snapping intact. Pinned by a headful case that grabs the bar clear of the strip and expects the dock zone to light up; it times out without the fix. --- .../api/decorated-window-tao.api | 6 +- .../dev/nucleusframework/window/TitleBar.kt | 23 +++++++- .../nucleusframework/window/tao/Satellite.kt | 30 ++++++++-- .../tao/headful/SatelliteWorkspaceFixture.kt | 7 +++ .../headful/SatelliteWorkspaceHeadfulCases.kt | 57 +++++++++++++++++++ 5 files changed, 113 insertions(+), 10 deletions(-) diff --git a/decorated-window-tao/api/decorated-window-tao.api b/decorated-window-tao/api/decorated-window-tao.api index f81e923fe..742c9a3cf 100644 --- a/decorated-window-tao/api/decorated-window-tao.api +++ b/decorated-window-tao/api/decorated-window-tao.api @@ -7,8 +7,8 @@ public final class dev/nucleusframework/window/ComposableSingletons$DialogTitleB public final class dev/nucleusframework/window/ComposableSingletons$TitleBarKt { public static final field INSTANCE Ldev/nucleusframework/window/ComposableSingletons$TitleBarKt; public fun ()V - public final fun getLambda$-880964242$Nucleus_decorated_window_tao ()Lkotlin/jvm/functions/Function2; - public final fun getLambda$-985436865$Nucleus_decorated_window_tao ()Lkotlin/jvm/functions/Function4; + public final fun getLambda$-1158225253$Nucleus_decorated_window_tao ()Lkotlin/jvm/functions/Function4; + public final fun getLambda$-1381932086$Nucleus_decorated_window_tao ()Lkotlin/jvm/functions/Function2; public final fun getLambda$1948865750$Nucleus_decorated_window_tao ()Lkotlin/jvm/functions/Function4; public final fun getLambda$555209157$Nucleus_decorated_window_tao ()Lkotlin/jvm/functions/Function2; } @@ -18,7 +18,7 @@ public final class dev/nucleusframework/window/DialogTitleBarKt { } public final class dev/nucleusframework/window/TitleBarKt { - public static final fun BasicTitleBar-lVb_Clg (Ldev/nucleusframework/window/DecoratedWindowScope;Landroidx/compose/ui/Modifier;JLdev/nucleusframework/window/styling/TitleBarStyle;Ldev/nucleusframework/window/ControlButtonsDirection;Ldev/nucleusframework/window/TitleBarLayoutPolicy;Lkotlin/jvm/functions/Function2;Lkotlin/jvm/functions/Function4;Landroidx/compose/runtime/Composer;II)V + public static final fun BasicTitleBar-IkByU14 (Ldev/nucleusframework/window/DecoratedWindowScope;Landroidx/compose/ui/Modifier;JLdev/nucleusframework/window/styling/TitleBarStyle;Ldev/nucleusframework/window/ControlButtonsDirection;Ldev/nucleusframework/window/TitleBarLayoutPolicy;ZLkotlin/jvm/functions/Function2;Lkotlin/jvm/functions/Function4;Landroidx/compose/runtime/Composer;II)V public static final fun TitleBar-TgFrcIs (Ldev/nucleusframework/window/DecoratedWindowScope;Landroidx/compose/ui/Modifier;JLdev/nucleusframework/window/styling/TitleBarStyle;Ldev/nucleusframework/window/ControlButtonsDirection;Lkotlin/jvm/functions/Function2;Lkotlin/jvm/functions/Function4;Landroidx/compose/runtime/Composer;II)V } diff --git a/decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/TitleBar.kt b/decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/TitleBar.kt index 2c76416dc..9bcbdd8db 100644 --- a/decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/TitleBar.kt +++ b/decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/TitleBar.kt @@ -105,6 +105,21 @@ public fun DecoratedWindowScope.TitleBar( ) } +/** + * [TitleBar] with the measure policy left open, for chrome that needs a + * different arrangement than the platform default — a strip that fills the + * space between the platform controls, for instance + * ([TitleBarLayoutPolicy.FillCenter]). + * + * @param nativeWindowDrag whether pressing the bar starts the platform's own + * interactive move.

An application whose only windows come from the workspace never opened one. The list is now mirrored out through an effect. - **`onLastWindowClosed` fired at startup.** The workspace is empty on the first composition too, so the documented usage — wiring it to `exitApplication` — quit the app before it opened. It now fires per non-empty → empty transition, and again if the app carries on. - **a single-tab window could never be merged.** Its own strip travels under the pointer for the whole drag and it is also the focused window, so `dropTargetAt` answered with it every time and the `takeIf` that rejected it left no target at all. `excludeGroup` makes the search look *past* a group instead of stopping at it. - **the strip dropped tabs it had no room for.** `widthIn(min = …)` without a weight served the first tabs their full width and left the last ones zero-wide: present in the model, unclickable on screen. Tabs now share the strip and shrink together, capped at `TabMaxWidth`, the way a browser's do. Also: a programmatic `tearOff` of the only tab of a window recorded a position that nothing applied — it now requests the placement, so the window really moves; and `TabStrip` takes a `trailing` slot for the new-tab button, inside the strip so it stays one drop target. --- .../api/decorated-window-tao.api | 12 +++++-- .../window/tao/TabDragSessions.kt | 5 +-- .../nucleusframework/window/tao/TabStrip.kt | 20 ++++++++--- .../nucleusframework/window/tao/TabWindows.kt | 35 +++++++++++++++++-- .../window/tao/TabWorkspace.kt | 19 +++++++--- .../window/tao/TabWorkspaceTest.kt | 30 ++++++++++++++++ .../window/tao/TaoSceneTestBattery.kt | 3 ++ 7 files changed, 107 insertions(+), 17 deletions(-) diff --git a/decorated-window-tao/api/decorated-window-tao.api b/decorated-window-tao/api/decorated-window-tao.api index 742c9a3cf..bece0eaa3 100644 --- a/decorated-window-tao/api/decorated-window-tao.api +++ b/decorated-window-tao/api/decorated-window-tao.api @@ -185,6 +185,12 @@ public final class dev/nucleusframework/window/tao/ComposableSingletons$Satellit public final fun getLambda$660144339$Nucleus_decorated_window_tao ()Lkotlin/jvm/functions/Function3;

charset=UTF-8 Content-Transfer-Encoding: 8bit Real windows, real drags, four themes — the shapes the archetype is actually used in, and the ones it broke in. - **lifecycle** (10): the bootstrap the app-level regression hid, the last-window report per emptying, a window closed by the user taking its own tabs and no others, the last tab out of a window taking the window, a tab dropped from composition keeping its place, a closed tab redeclared as a new one, everything going down at once, a snapshot restored after every window was destroyed, a restore under a live drag, a new tab finding a window after the active one was dropped. - **mouse** (5, AWT Robot): a reorder that must not rebuild the body, a press that never moves, a click anywhere in a tab — top edge to bottom edge, since a tab is one target and not a patchwork of a grip and a selector — a hover across two strips and back, a flick. - **motion** (7): teleports between strips with nothing in between, 40 crossings of the strip edge asserted with no settle at all, off-screen and non-finite samples, the single-tab window drag, a target window moved and resized mid-gesture, drags back to back. - **concurrency** (6) and **storms** (5): a dozen tabs over four windows and back, declarations interleaved with tear-offs, churn with the travelling tab's state checked every round, five live sessions ended out of order, tabs and whole windows closed mid-gesture, 200 selections, 120 reorders, 400 pointer samples in one drag, windows stacked on the same pixel where only focus recency decides, a snapshot converging back after a burst. `MacDisplayModeTool` now spaces consecutive display-mode flips out: two cases in one process could hand the WindowServer a second reconfiguration while it was still applying the first, and the waiting case timed out — `#507` failed in a full run and passed alone. Shared helpers move to the fixture (`awaitMappedStrip`, `stripPointPx`, `farFromStripPx`, `tabRectPx`, `robotSkipReason`, `lastWindowClosedCount`); `robotDragTo` joins the robot helpers, for a case that has to hover one target before dropping on another. --- .../window/tao/headful/MacDisplayModeTool.kt | 21 + .../tao/headful/SatelliteWorkspaceFixture.kt | 32 + .../TabWorkspaceConcurrencyHeadfulCases.kt | 403 +++++++++++++ .../window/tao/headful/TabWorkspaceFixture.kt | 62 +- .../tao/headful/TabWorkspaceHeadfulCases.kt | 4 + .../TabWorkspaceLifecycleHeadfulCases.kt | 562 ++++++++++++++++++ .../headful/TabWorkspaceMotionHeadfulCases.kt | 497 ++++++++++++++++ .../headful/TabWorkspaceMouseHeadfulCases.kt | 304 ++++++++++ .../headful/TabWorkspaceStormHeadfulCases.kt | 377 ++++++++++++ .../headful/TabWorkspaceStressHeadfulCases.kt | 18 - .../tao/headful/TaoHeadfulTestSuiteMain.kt | 5 + 11 files changed, 2266 insertions(+), 19 deletions(-) create mode 100644 decorated-window-tao/src/test/kotlin/dev/nucleusframework/window/tao/headful/TabWorkspaceConcurrencyHeadfulCases.kt create mode 100644 decorated-window-tao/src/test/kotlin/dev/nucleusframework/window/tao/headful/TabWorkspaceLifecycleHeadfulCases.kt create mode 100644 decorated-window-tao/src/test/kotlin/dev/nucleusframework/window/tao/headful/TabWorkspaceMotionHeadfulCases.kt create mode 100644 decorated-window-tao/src/test/kotlin/dev/nucleusframework/window/tao/headful/TabWorkspaceMouseHeadfulCases.kt create mode 100644 decorated-window-tao/src/test/kotlin/dev/nucleusframework/window/tao/headful/TabWorkspaceStormHeadfulCases.kt diff --git a/decorated-window-tao/src/test/kotlin/dev/nucleusframework/window/tao/headful/MacDisplayModeTool.kt b/decorated-window-tao/src/test/kotlin/dev/nucleusframework/window/tao/headful/MacDisplayModeTool.kt index 96cb57d6c..dcafd4642 100644 --- a/decorated-window-tao/src/test/kotlin/dev/nucleusframework/window/tao/headful/MacDisplayModeTool.kt +++ b/decorated-window-tao/src/test/kotlin/dev/nucleusframework/window/tao/headful/MacDisplayModeTool.kt @@ -33,6 +33,12 @@ internal object MacDisplayModeTool { /** `mode` is `1x`, `2x` or `query`; returns the helper's one-line report. */ fun run(mode: String): String { + // Two cases in one process can flip the display back to back — one + // restoring its original mode, the next asking for the other one.

**tabs-demo** — the archetype with the stock strip: documents declared once as tabs, windows that follow them, tear-off and merge by drag, a saveable draft and counter next to a plain `remember` one so the difference is on screen, layout snapshots, a "+" in the strip. - **jewel-tabs-demo** — the same workspace wearing IntelliJ's own tab chrome: Jewel's `TabStrip` and `TabData.Editor` draw the tabs, the workspace decides what they are. `TabData` carries no `Modifier`, so the slot, the drag grip and the click all go on the tab's *content*, which is made to fill the tab: split them and the tab ends up with a grip over the label and a sliver of padding that selects. - **tab-satellites-demo** — the two multi-window archetypes composed. One `SatelliteWorkspace` per tab *window*, whose palettes draw the tab that window is showing; per-document values live outside composition. Per window and not per document on purpose: hanging the membership on the tab body destroys a native palette window and creates another on every tab change, which flashes.

The gestures now ride the platform drag-and-drop session instead — the only pointer grab that crosses windows with coordinates. The source starts a session carrying an in-process token (SAME_APP only, so no foreign target ever sees it), the window under the pointer resolves the drop in its own coordinates and records it on the session, and the source acts on that record when the session ends. Chromium falls back to the same design on compositors without xdg-toplevel-drag, which GTK3 cannot reach: GDK3 exposes no accessor for a window's xdg_toplevel and creates the drag's wl_data_source inside gtk_drag_begin. The drag icon is a reduced snapshot of the dragged palette or panel, rendered through TaoWindow.contentSnapshot. On a floating satellite the header strip carries the gesture while a caption strip beside the window controls keeps the compositor's move — the split Chrome's tab strip and GIMP's dock tabs both land on. Two leaks found on the way: - nativeLinuxHandles asked tao for the Xlib display handle, whose raw_display_handle_rwh_06 opens a fresh X connection per call and never closes it; polling the surface kind exhausted the server's client limit mid-suite. The kind is cached per window now, and the Xlib branch never asks for that handle. - gtk_drag_begin's pointer grab is released by GTK handlers that run after ours, so returning as soon as drag-end fired left every window of the application deaf to the pointer for good. The session drains GTK's queue and ungrabs the seat before returning. Covered by 26 headful cases on a real Wayland session — contract, lifecycle, concurrency, bursts, churn, edge cases — plus unit tests for the dock-zone math, the private payload and the transfer wiring, whose completion callback is the only thing that ends a session. --- CLAUDE.md | 2 +- .../nucleusframework/window/tao/DockLayout.kt | 85 +- .../nucleusframework/window/tao/Satellite.kt | 72 +- .../window/tao/SatelliteDragSessions.kt | 58 ++ .../window/tao/SatelliteWindow.kt | 39 +- .../window/tao/SatelliteWorkspace.kt | 136 +++- .../window/tao/TabDragSessions.kt | 69 +- .../nucleusframework/window/tao/TabStrip.kt | 82 +- .../window/tao/TabWorkspace.kt | 60 +- .../nucleusframework/window/tao/TaoWindow.kt | 45 +- .../window/tao/dnd/TaoDragAndDropManager.kt | 25 +- .../window/tao/dnd/TaoPrivateTransfer.kt | 46 ++ .../window/tao/ffi/NativeTaoLinuxDndBridge.kt | 18 + .../tao/scene/TaoComposeSceneHostLinux.kt | 147 ++++ .../window/tao/workspace/CrossWindowDrag.kt | 13 +- .../window/tao/workspace/HostGeometry.kt | 9 +- .../window/tao/workspace/ScreenPlacement.kt | 47 ++ .../window/tao/workspace/TransferDrag.kt | 386 +++++++++ .../src/main/native/src/platform/linux/dnd.rs | 137 +++- .../main/native/src/platform/linux/handles.rs | 31 +- .../tao/OutboundDragPumpNativeSmokeTest.kt | 7 + .../window/tao/TaoSceneTestBattery.kt | 40 + .../tao/TaoSceneTestBatteryDriftTest.kt | 2 + .../tao/headful/SatelliteWorkspaceFixture.kt | 12 +- .../tao/headful/TaoHeadfulTestSuiteMain.kt | 2 + .../headful/WaylandWorkspaceHeadfulCases.kt | 291 +++++++ .../WaylandWorkspaceStressHeadfulCases.kt | 743 ++++++++++++++++++ .../tao/headful/WaylandWorkspaceSupport.kt | 217 +++++ .../window/tao/workspace/TransferDragTest.kt | 188 +++++ 29 files changed, 2944 insertions(+), 65 deletions(-) create mode 100644 decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/dnd/TaoPrivateTransfer.kt create mode 100644 decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/workspace/ScreenPlacement.kt create mode 100644 decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/workspace/TransferDrag.kt create mode 100644 decorated-window-tao/src/test/kotlin/dev/nucleusframework/window/tao/headful/WaylandWorkspaceHeadfulCases.kt create mode 100644 decorated-window-tao/src/test/kotlin/dev/nucleusframework/window/tao/headful/WaylandWorkspaceStressHeadfulCases.kt create mode 100644 decorated-window-tao/src/test/kotlin/dev/nucleusframework/window/tao/headful/WaylandWorkspaceSupport.kt create mode 100644 decorated-window-tao/src/test/kotlin/dev/nucleusframework/window/tao/workspace/TransferDragTest.kt diff --git a/CLAUDE.md b/CLAUDE.md index 1da5db029..42e4ef94b 100644 --- a/CLAUDE.md +++ b/CLAUDE.md @@ -37,7 +37,7 @@ Published releases are `2.5.x` (latest tag `v2.5.0`).

On a satellite that reads as the palette flashing at the screen's default spot for a few hundred milliseconds before snapping beside its document. The move is now issued before the show, which GTK and Win32 both carry into the initial placement, and re-applied once the frame is real — that still defeats the WM's own map-time placement and repairs an early move that was lost, which is what the wait was there for. Two anchoring bugs surfaced behind it: - a satellite declared inside its parent's content composes in the frame the parent window is created, so its anchor was resolved against a frame of size zero and latched at `parentLeft + gap` instead of `parentRight + gap`. It now waits for the parent to have a real frame, and `anchoredOriginPx` returns null for a frame with no size so a caller retries rather than latching; - a satellite stepping back in after its parent left a maximized or fullscreen frame was aligned against geometry the platform had not finished changing, and every move it made while hidden was skipped. The re-align now happens again on the first parent geometry that lands afterwards. `satellite anchors to the parent's right edge and follows it` has been failing on a real GNOME session for weeks and was recorded as an environment quirk; it passes now. --- .../window/tao/DecoratedWindowComposable.kt | 21 +++-- .../window/tao/SatelliteWindow.kt | 81 ++++++++++++++++++- 2 files changed, 95 insertions(+), 7 deletions(-) diff --git a/decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/DecoratedWindowComposable.kt b/decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/DecoratedWindowComposable.kt index 97afac4de..79fdcb013 100644 --- a/decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/DecoratedWindowComposable.kt +++ b/decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/DecoratedWindowComposable.kt @@ -469,13 +469,22 @@ public fun ApplicationScope.DecoratedWindow( // outer origin so the ghost tracks the cursor instead of // landing up/left by the decoration inset + outer offset. val (xDp, yDp) = absolutePositionForPopup(window, pos) - // X11: a move issued before the window is mapped raced the map - // itself — under Xvfb/openbox the window intermittently stayed at - // GTK's unallocated 1×1 for good.

What is new, by theme: - **file drops** (14) — inbound drags driven through the same funnel the platform callbacks use, so the synthetic transferable, the Compose drag-and-drop tree and the app's own target all run: paths read back through `awtTransferable`, drops clear of every target, a target that refuses the drag, an empty payload, unreachable paths, 300 samples, 20 drops back to back, a drop crossing a live tab drag, and one aimed at a window closing under it; - **the two archetypes composed** (18) — one satellite workspace per tab window, as in `examples/tab-satellites-demo`: a tab change redraws the palette without recreating it, a torn-off tab arrives with palettes of its own, a docked panel survives a tab change and outlives the tab it was drawing, and a tab drag and a palette drag run at once; - **the pointer** (16) — clicks, bursts of forty, sixty alternating, sub-pixel drift, a wobble under the touch slop, real drag / tear-off / merge gestures, the close button, the buttons that must do nothing, and a pointer that leaves the window mid-drag; - **placement** (4) — where a window is the first time it is *seen*, sampled every 8 ms and failed on dwell rather than presence: a frame of WM placement is nobody's problem, half a second is; - **window extremes** (18) — transparent, one pixel across, 120 sizes in a burst, an animation running through it, an embedded native view's rect, a texture view with no source and one signalled 500 times; - **load** (8) — four animating windows with palettes: no window starved, anchoring converging while the owner never stops moving; - **monitors and scale** (14) — the logical/physical round trips that are only wrong on a HiDPI desktop, plus display hops; - **races** (10) — background threads, coroutines on one group, a restore between a tear-off and its window, everything closed at once. Two mechanisms make this possible where `java.awt.Robot` cannot inject at all (a Wayland compositor refuses the portal session): pointer events are posted through `TaoWindow.dispatch`, the same entry the native loop uses, and inbound drags through the window's drop-target lambda. Everything above the JNI boundary is the real pipeline — the sub-pixel deadband, the resize-edge band, hit-testing, the touch slop, the drag handles. Cases that need something this host cannot provide report it: a second display, or a native handle no test module can fabricate on Linux. --- .../headful/MonitorAndScaleHeadfulCases.kt | 629 +++++++++++++ .../headful/SatellitePlacementHeadfulCases.kt | 319 +++++++ .../headful/TabSatellitesChaosHeadfulCases.kt | 493 ++++++++++ .../tao/headful/TabSatellitesHeadfulCases.kt | 506 ++++++++++ .../window/tao/headful/TabWorkspaceFixture.kt | 69 +- .../TabWorkspacePointerHeadfulCases.kt | 722 +++++++++++++++ .../tao/headful/TaoHeadfulTestSuiteMain.kt | 9 + .../tao/headful/WindowExtremesHeadfulCases.kt | 871 ++++++++++++++++++ .../tao/headful/WorkspaceChaosSupport.kt | 604 ++++++++++++ .../headful/WorkspaceFileDropHeadfulCases.kt | 617 +++++++++++++ .../tao/headful/WorkspaceLoadHeadfulCases.kt | 579 ++++++++++++ .../tao/headful/WorkspaceRaceHeadfulCases.kt | 616 +++++++++++++ 12 files changed, 6033 insertions(+), 1 deletion(-) create mode 100644 decorated-window-tao/src/test/kotlin/dev/nucleusframework/window/tao/headful/MonitorAndScaleHeadfulCases.kt create mode 100644 decorated-window-tao/src/test/kotlin/dev/nucleusframework/window/tao/headful/SatellitePlacementHeadfulCases.kt create mode 100644 decorated-window-tao/src/test/kotlin/dev/nucleusframework/window/tao/headful/TabSatellitesChaosHeadfulCases.kt create mode 100644 decorated-window-tao/src/test/kotlin/dev/nucleusframework/window/tao/headful/TabSatellitesHeadfulCases.kt create mode 100644 decorated-window-tao/src/test/kotlin/dev/nucleusframework/window/tao/headful/TabWorkspacePointerHeadfulCases.kt create mode 100644 decorated-window-tao/src/test/kotlin/dev/nucleusframework/window/tao/headful/WindowExtremesHeadfulCases.kt create mode 100644 decorated-window-tao/src/test/kotlin/dev/nucleusframework/window/tao/headful/WorkspaceChaosSupport.kt create mode 100644 decorated-window-tao/src/test/kotlin/dev/nucleusframework/window/tao/headful/WorkspaceFileDropHeadfulCases.kt create mode 100644 decorated-window-tao/src/test/kotlin/dev/nucleusframework/window/tao/headful/WorkspaceLoadHeadfulCases.kt create mode 100644 decorated-window-tao/src/test/kotlin/dev/nucleusframework/window/tao/headful/WorkspaceRaceHeadfulCases.kt diff --git a/decorated-window-tao/src/test/kotlin/dev/nucleusframework/window/tao/headful/MonitorAndScaleHeadfulCases.kt b/decorated-window-tao/src/test/kotlin/dev/nucleusframework/window/tao/headful/MonitorAndScaleHeadfulCases.kt new file mode 100644 index 000000000..ec941764b --- /dev/null +++ b/decorated-window-tao/src/test/kotlin/dev/nucleusframework/window/tao/headful/MonitorAndScaleHeadfulCases.kt @@ -0,0 +1,629 @@ +package dev.nucleusframework.window.tao.headful + +import androidx.compose.foundation.background +import androidx.compose.foundation.layout.Box +import androidx.compose.foundation.layout.fillMaxSize +import androidx.compose.runtime.SideEffect +import androidx.compose.runtime.mutableStateOf +import androidx.compose.ui.Modifier +import androidx.compose.ui.geometry.Offset +import androidx.compose.ui.graphics.Color +import androidx.compose.ui.platform.LocalWindowInfo +import androidx.compose.ui.unit.DpOffset +import androidx.compose.ui.unit.DpSize +import androidx.compose.ui.unit.IntSize +import androidx.compose.ui.unit.dp +import dev.nucleusframework.window.tao.DockSide +import dev.nucleusframework.window.tao.SatelliteWorkspace +import dev.nucleusframework.window.tao.TaoMonitor +import dev.nucleusframework.window.tao.TaoMonitors +import dev.nucleusframework.window.tao.TaoWindow +import dev.nucleusframework.window.tao.WindowAnchor +import dev.nucleusframework.window.tao.WindowConstraintAdjustment +import dev.nucleusframework.window.tao.WindowPositioner +import kotlin.math.abs +import kotlin.math.roundToInt + +/** + * Monitors and scale, on real windows. + * + * Two coordinate spaces run through every one of these APIs: windows are + * *placed* in logical pixels and *measured* in physical ones, and the ratio + * between them belongs to a monitor rather than to the application.

With the button already up the request is silently ignored — no protocol error, no grab, and so no `cancelled` / `dnd_finished` on the source. GTK therefore never emits `drag-end`, and `start_outbound`'s cooperative `while !done { main_iteration_do(true) }` spun for the rest of the process's life. Tao's event loop never ran again, which is the freeze; the pump kept painting, which is why the app still looked alive. The gesture gets there whenever the client falls behind the compositor: Compose crosses the touch slop on a queued motion that tao dispatches after the real release was already delivered. Captured with WAYLAND_DEBUG on tab-satellites-demo — the three working drags issue `start_drag` with a press serial, the hanging one issues it 10 ms after `wl_pointer.button(..., 0)`. A maximized window with satellites is the easy way to see it, being the slowest to render. Two guards, both in the Linux outbound path: - `buttons_held` reads the seat's button mask off GDK's own device state, and a session whose button is already up is refused before `gtk_drag_begin` — Compose sees a transfer that did not start and the gesture is a clean no-op. - the wait loop is now bounded past the release: once no button is held, a session that has not ended within a second is cancelled via `gtk_drag_cancel`, which runs the ordinary teardown. Never bounded during the drag, so holding a legitimate drag is unaffected. --- .../src/main/native/src/platform/linux/dnd.rs | 93 +++++++++++++++++++ 1 file changed, 93 insertions(+) diff --git a/decorated-window-tao/src/main/native/src/platform/linux/dnd.rs b/decorated-window-tao/src/main/native/src/platform/linux/dnd.rs index d281ff78c..331c14903 100644 --- a/decorated-window-tao/src/main/native/src/platform/linux/dnd.rs +++ b/decorated-window-tao/src/main/native/src/platform/linux/dnd.rs @@ -98,6 +98,22 @@ const DRAG_PUMP_INTERVAL_MS: u64 = 8; /// teardown is a few events, and the loop stops as soon as none are pending. const DRAG_TEARDOWN_ITERATIONS: usize = 64; +/// How long the session may run on with no pointer button held before it is +/// declared dead and cancelled. +/// +/// A legitimate session ends within a frame or two of the release — `drag-end` +/// follows the compositor's `dnd_finished` / `cancelled` immediately.

This one draws 200 actions from a seeded `Random` over one `SatelliteWorkspace`: open / close a palette, dock / undock it, open and destroy host windows, begin / move / end / cancel a drag, maximize, resize, inject a scale change, flip the visibility sweep. Each action is one call plus a 25 ms settle — it deliberately does not wait for a steady state, because the states worth finding are the ones a gesture is interrupted in. A quarter of the drag samples are what a coalesced flick or a display unplug actually hands over: a point on no screen, or NaN. What it asserts is not "the right thing happened" — for a random sequence there is no such expectation — but that nothing is left orphaned and nothing wedges: - the workspace never names a window it does not have: no member is a destroyed window, no satellite is docked into a non-member, no owner or pin points outside the membership; - no drag feedback outlives its drag, and no satellite keeps composing in two hosts; - native windows do not accumulate, and come back down to exactly the quiesced set at the end; - the closing phase asks for a plain state (visible, nothing docked, one window) and it has to converge — a workspace that survived the storm but can no longer be brought back is broken, it just fails later, in the app. Deadlocks need a watcher that is not on the loop. The driver runs *on* `Dispatchers.Main`, so if the Tao loop and the dispatcher ever wait on each other the driver stops too and cannot fail its own case: the suite would just hit its deadline with nothing said. `MainLoopWatchdog` posts heartbeats from its own thread and dumps every stack the moment one goes unanswered for 8 s, which is the whole diagnosis; a late one is reported as the worst stall and fails the case. Each action also carries a short 5 s budget, so a wedged action names itself. A native panic cannot be asserted at all — a Rust `panic!` across JNI aborts the process and no Kotlin frame survives it. Reaching the end of the case is the assertion, and the seed is what makes an abort reproducible. Failures carry the seed, the workspace state and the last 40 actions; `-Dnucleus.tao.headful.monkeySeed=` replays the action sequence. It does not replay the run — the state each action lands on depends on what the loop got done in the milliseconds before it — so the journal, not the seed, is what identifies a sequence to promote into a case of its own. A green run prints what it reached and fails if it reached nothing, so the case cannot quietly stop testing anything the day a guard starts refusing early. --- decorated-window-tao/build.gradle.kts | 4 + .../SatelliteWorkspaceMonkeyHeadfulCases.kt | 955 ++++++++++++++++++ .../tao/headful/TaoHeadfulTestSuiteMain.kt | 1 + 3 files changed, 960 insertions(+) create mode 100644 decorated-window-tao/src/test/kotlin/dev/nucleusframework/window/tao/headful/SatelliteWorkspaceMonkeyHeadfulCases.kt diff --git a/decorated-window-tao/build.gradle.kts b/decorated-window-tao/build.gradle.kts index 9224e2386..34e8a2ef5 100644 --- a/decorated-window-tao/build.gradle.kts +++ b/decorated-window-tao/build.gradle.kts @@ -157,6 +157,10 @@ val taoHeadfulTest by tasks.registering(JavaExec::class) { System.getProperty("nucleus.tao.headful.filter")?.let { systemProperty("nucleus.tao.headful.filter", it) } + // Replays a red monkey run: the case prints the seed it used. + System.getProperty("nucleus.tao.headful.monkeySeed")?.let { + systemProperty("nucleus.tao.headful.monkeySeed", it) + } System.getProperty("nucleus.issue576.samples")?.let { systemProperty("nucleus.issue576.samples", it) } diff --git a/decorated-window-tao/src/test/kotlin/dev/nucleusframework/window/tao/headful/SatelliteWorkspaceMonkeyHeadfulCases.kt b/decorated-window-tao/src/test/kotlin/dev/nucleusframework/window/tao/headful/SatelliteWorkspaceMonkeyHeadfulCases.kt new file mode 100644 index 000000000..3f2cb3eea --- /dev/null +++ b/decorated-window-tao/src/test/kotlin/dev/nucleusframework/window/tao/headful/SatelliteWorkspaceMonkeyHeadfulCases.kt @@ -0,0 +1,955 @@ +package dev.nucleusframework.window.tao.headful + +import androidx.compose.foundation.background +import androidx.compose.foundation.layout.Box +import androidx.compose.foundation.layout.fillMaxSize +import androidx.compose.runtime.Composable +import androidx.compose.runtime.DisposableEffect +import androidx.compose.runtime.SideEffect +import androidx.compose.runtime.key +import androidx.compose.runtime.mutableStateListOf +import androidx.compose.runtime.mutableStateOf +import androidx.compose.runtime.remember +import androidx.compose.ui.Modifier +import androidx.compose.ui.geometry.Offset +import androidx.compose.ui.graphics.Color +import androidx.compose.ui.unit.DpSize +import androidx.compose.ui.unit.dp +import androidx.compose.ui.window.WindowPosition +import androidx.compose.ui.window.rememberWindowState +import dev.nucleusframework.window.tao.ApplicationScope +import dev.nucleusframework.window.tao.DecoratedWindow +import dev.nucleusframework.window.tao.DockLayout +import dev.nucleusframework.window.tao.DockSide +import dev.nucleusframework.window.tao.JoinSatelliteWorkspace +import dev.nucleusframework.window.tao.LocalTaoWindow +import dev.nucleusframework.window.tao.Satellite +import dev.nucleusframework.window.tao.SatelliteDragOrigin +import dev.nucleusframework.window.tao.SatelliteDragSession +import dev.nucleusframework.window.tao.SatelliteEntry +import dev.nucleusframework.window.tao.SatellitePlacement +import dev.nucleusframework.window.tao.SatelliteScope +import dev.nucleusframework.window.tao.SatelliteWorkspace +import dev.nucleusframework.window.tao.TaoApplication +import dev.nucleusframework.window.tao.TaoEventCode +import dev.nucleusframework.window.tao.TaoWindow +import kotlinx.coroutines.CoroutineScope +import kotlinx.coroutines.Dispatchers +import kotlinx.coroutines.TimeoutCancellationException +import kotlinx.coroutines.cancel +import kotlinx.coroutines.launch +import kotlinx.coroutines.withTimeout +import java.util.concurrent.ConcurrentLinkedDeque +import java.util.concurrent.CountDownLatch +import java.util.concurrent.TimeUnit +import java.util.concurrent.atomic.AtomicBoolean +import java.util.concurrent.atomic.AtomicLong +import kotlin.collections.randomOrNull +import kotlin.concurrent.thread +import kotlin.math.max +import kotlin.math.roundToInt +import kotlin.random.Random + +/** + * The monkey: [MONKEY_ACTIONS] random actions on one [SatelliteWorkspace], in + * an order no case would ever write by hand. + * + * Every other workspace case drives a gesture the way a user performs it — + * begin, move, release, assert.

Its own body — its `remember`s, its scroll position, its saveable registry — is the one that got destroyed. `DockSideStack` composed its panels in a `forEachIndexed` with no key, so Compose identified them by their position on the side. Going from `[first, second]` to `[second]` is not read as "first left" but as "one slot fewer": slot 0 is kept and slot 1 disposed, so `first`'s subtree is recycled for `second` and `second`'s own subtree is the one thrown away. Found by the seeded monkey (`-Dnucleus.tao.headful.monkeySeed=424242`), which reached it as a palette still composing a panel in a window it had already been undocked from, while the palette actually docked there composed nothing at all. The instrumented trace names the two halves: +tools docked@1#17 tools docked, panel index 0 +outline docked@1#18 outline docked, panel index 1 +tools floating@11#19 tools undocked, floating window up -outline docked@1#18 outline's panel is the one disposed `key(entry.id)` around each panel, in both orientations. `Satellite` and `Tab` already key their own declarations; this is the level below them that was missing one. `panelsOnOneSideKeepTheirOwnSubtree` pins it deterministically rather than leaving it to the monkey's luck: two palettes docked right, each body publishing the id it was composed for plus a `remember` marker, the first undocked, and the survivor has to answer with its own id and its own marker. It fails without the key (`live bodies {0=second, 2=first}`) and passes with it. --- .../nucleusframework/window/tao/DockLayout.kt | 25 ++++- .../headful/SatelliteWorkspaceHeadfulCases.kt | 104 ++++++++++++++++++ 2 files changed, 124 insertions(+), 5 deletions(-) diff --git a/decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/DockLayout.kt b/decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/DockLayout.kt index 4bfc77677..1703dab9c 100644 --- a/decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/DockLayout.kt +++ b/decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/DockLayout.kt @@ -17,6 +17,7 @@ import androidx.compose.foundation.layout.size import androidx.compose.foundation.layout.width import androidx.compose.runtime.Composable import androidx.compose.runtime.getValue +import androidx.compose.runtime.key import androidx.compose.runtime.mutableStateOf import androidx.compose.runtime.remember import androidx.compose.runtime.setValue @@ -288,7 +289,17 @@ private fun Modifier.dashedOutline( ) } -/** The panels docked on one side, sharing the side equally along its length.

A frame of 1x1 is GTK's placeholder for "not laid out yet", not a size, so `> 0` was the wrong test: anchoring against a 1px-tall satellite centres its top edge on the parent rather than its middle. `reanchor`, `captureOffset` and `anchoredOriginPx` all go through `hasRealFrame` now. And one successful re-anchor is not enough. A window manager can report a real frame at the origin and apply the requested position several frames later — openbox under Xvfb takes tens of milliseconds, a loaded desktop longer — so the satellite was anchored to a parent that was never there and then trailed it by exactly the distance the parent moved after the map. Keep re-anchoring until the parent's frame has held still for three polls, which is the only signal a WM gives that placement is done, and stop as soon as a reparent swaps the anchoring: the satellite must stay where it is on screen when it changes owner. Stepping back in after a maximized or fullscreen stint has the same shape: re-showing the window races the single move the step-back path issues, and when the move loses the satellite stays where it was before it stepped aside.

Every "mapped with a real size" gate accepted GTK's 1x1 placeholder, so a case proceeded against it and asserted on the placeholder: a torn-off window "1.0 dp wide", a robot gesture aimed at a negative screen coordinate. They all go through one `hasRealFramePx` now, which is `> 1` for the reason the helper documents. `composedIn` recorded one window per tab. A tab that leaves a multi-tab window is composed in *both* windows until the window it left renders again — Compose coalesces frames, so the two hosts genuinely overlap while a frame is pending — and the arriving host overwrote the departing one, whose disposal then erased the entry for a body that was still composed. It is a list of hosts, published for the body's lifetime rather than on every recomposition: a body that outlives its selection for a frame never recomposes again. `tab workspace never drops into a minimized window` ends with three windows covering the same strip, so which of them answers a point on it is decided by focus recency, not geometry. Wait for the platform to grant the focus the case asks for instead of assuming it was granted. The `#582` clipboard cases now skip when the window backend is forced onto XWayland inside a Wayland session: `wl-copy` owns the Wayland selection, so the two are on different clipboards and the case can only time out. CI has no `wl-copy` at all, which is why only the X11 leg run from a developer machine ever saw it. --- .../tao/headful/ClipboardHeadfulCases.kt | 31 ++++++++-- .../headful/SatelliteWindowHeadfulCases.kt | 3 +- .../tao/headful/SatelliteWorkspaceFixture.kt | 3 +- .../headful/SatelliteWorkspaceHeadfulCases.kt | 10 ++-- .../TabWorkspaceConcurrencyHeadfulCases.kt | 2 +- .../window/tao/headful/TabWorkspaceFixture.kt | 56 +++++++++++++------ .../tao/headful/TabWorkspaceHeadfulCases.kt | 2 +- .../TabWorkspaceLifecycleHeadfulCases.kt | 4 +- .../headful/TabWorkspaceMotionHeadfulCases.kt | 2 +- .../headful/TabWorkspaceStormHeadfulCases.kt | 2 +- .../headful/TabWorkspaceStressHeadfulCases.kt | 14 ++++- .../tao/headful/TaoHeadfulTestSuiteMain.kt | 3 +- .../tao/headful/TaoWindowTestHarness.kt | 15 +++++ .../tao/headful/WorkspaceChaosSupport.kt | 14 +++-- 14 files changed, 115 insertions(+), 46 deletions(-) diff --git a/decorated-window-tao/src/test/kotlin/dev/nucleusframework/window/tao/headful/ClipboardHeadfulCases.kt b/decorated-window-tao/src/test/kotlin/dev/nucleusframework/window/tao/headful/ClipboardHeadfulCases.kt index 65e300760..3aea1ed13 100644 --- a/decorated-window-tao/src/test/kotlin/dev/nucleusframework/window/tao/headful/ClipboardHeadfulCases.kt +++ b/decorated-window-tao/src/test/kotlin/dev/nucleusframework/window/tao/headful/ClipboardHeadfulCases.kt @@ -68,7 +68,7 @@ internal object ClipboardHeadfulCases { private fun gtkClipboardReadsForeignSelection(): TaoWindowTestCase = clipboardCase( name = "#582 GTK clipboard reads a selection owned by another process", - skip = { linuxWithNativeClipboard() ?: requireTool("wl-copy") }, + skip = { clipboardSkipReason("wl-copy") }, ) { focusWindow -> val text = "nucleus-582-foreign$PROBE_SUFFIX" publishExternally(text.toByteArray(), "text/plain;charset=utf-8") @@ -83,7 +83,7 @@ internal object ClipboardHeadfulCases { private fun gtkClipboardPublishesToTheDesktop(): TaoWindowTestCase = clipboardCase( name = "#582 GTK clipboard publishes the app's selection to the desktop", - skip = { linuxWithNativeClipboard() ?: requireTool("wl-paste") }, + skip = { clipboardSkipReason("wl-paste") }, ) { focusWindow -> focusWindow() @@ -111,7 +111,7 @@ internal object ClipboardHeadfulCases { private fun gtkClipboardReadsForeignImage(): TaoWindowTestCase = clipboardCase( name = "#582 GTK clipboard reads an image published by another process", - skip = { linuxWithNativeClipboard() ?: requireTool("wl-copy") }, + skip = { clipboardSkipReason("wl-copy") }, ) { focusWindow -> publishExternally(probePng(), "image/png") focusWindow() @@ -126,7 +126,7 @@ internal object ClipboardHeadfulCases { private fun gtkClipboardPublishesAnImage(): TaoWindowTestCase = clipboardCase( name = "#582 GTK clipboard publishes an image to the desktop", - skip = { linuxWithNativeClipboard() ?: requireTool("wl-paste") }, + skip = { clipboardSkipReason("wl-paste") }, ) { focusWindow -> focusWindow() @@ -148,7 +148,7 @@ internal object ClipboardHeadfulCases { private fun gtkClipboardRoundTripsAFileList(): TaoWindowTestCase = clipboardCase( name = "#582 GTK clipboard round-trips a file list", - skip = { linuxWithNativeClipboard() ?: requireTool("wl-copy") }, + skip = { clipboardSkipReason("wl-copy") }, ) { focusWindow -> val file = withContext(Dispatchers.IO) { File.createTempFile("nucleus-582-", ".txt") } file.deleteOnExit() @@ -332,6 +332,27 @@ internal object ClipboardHeadfulCases { } }.getOrNull() + /** + * Why this case cannot run here: no GTK clipboard, no [tool], or a peer + * that would not share a selection with the app. + * + * `wl-copy` / `wl-paste` own the *Wayland* selection, so they only speak + * to the app when the app is on Wayland too.

The settled position comes from the sampling now, and samples with no real frame are not sampled at all. --- .../headful/MonitorAndScaleHeadfulCases.kt | 2 +- .../headful/SatellitePlacementHeadfulCases.kt | 28 +++++++++++++------ .../tao/headful/SatelliteWorkspaceFixture.kt | 24 ++++++++++++++++ .../headful/SatelliteWorkspaceHeadfulCases.kt | 7 ++--- .../SatelliteWorkspaceStressHeadfulCases.kt | 10 +++---- 5 files changed, 51 insertions(+), 20 deletions(-) diff --git a/decorated-window-tao/src/test/kotlin/dev/nucleusframework/window/tao/headful/MonitorAndScaleHeadfulCases.kt b/decorated-window-tao/src/test/kotlin/dev/nucleusframework/window/tao/headful/MonitorAndScaleHeadfulCases.kt index ec941764b..59c423359 100644 --- a/decorated-window-tao/src/test/kotlin/dev/nucleusframework/window/tao/headful/MonitorAndScaleHeadfulCases.kt +++ b/decorated-window-tao/src/test/kotlin/dev/nucleusframework/window/tao/headful/MonitorAndScaleHeadfulCases.kt @@ -273,7 +273,7 @@ internal object MonitorAndScaleHeadfulCases { awaitUntil("the layout published its geometry") { workspace.dockHostGeometry(window)?.layoutScreenRectPx() != null } - val layout = requireNotNull(workspace.dockHostGeometry(window)?.layoutScreenRectPx()) + val layout = awaitDockLayout(workspace, window) val scale = window.scaleFactor val bandPx = SatelliteWorkspace.DockZoneWidth.value * scale diff --git a/decorated-window-tao/src/test/kotlin/dev/nucleusframework/window/tao/headful/SatellitePlacementHeadfulCases.kt b/decorated-window-tao/src/test/kotlin/dev/nucleusframework/window/tao/headful/SatellitePlacementHeadfulCases.kt index 12cee77f8..a33171596 100644 --- a/decorated-window-tao/src/test/kotlin/dev/nucleusframework/window/tao/headful/SatellitePlacementHeadfulCases.kt +++ b/decorated-window-tao/src/test/kotlin/dev/nucleusframework/window/tao/headful/SatellitePlacementHeadfulCases.kt @@ -63,7 +63,7 @@ internal object SatellitePlacementHeadfulCases { driver = { val satellite = requireNotNull(satelliteWindow) { "the satellite never published itself" } val trajectory = sampleUntilAnchored(satellite, window) - assertNoFlash(trajectory, satellite, window) + assertNoFlash(trajectory, window) }, ) } @@ -97,7 +97,7 @@ internal object SatellitePlacementHeadfulCases { awaitUntil("a new satellite window appeared") { fixture.floatingWindow.value != null } val satellite = requireNotNull(fixture.floatingWindow.value) val trajectory = sampleUntilAnchored(satellite, window) - assertNoFlash(trajectory, satellite, window) + assertNoFlash(trajectory, window) }, ) } @@ -239,18 +239,23 @@ internal object SatellitePlacementHeadfulCases { val dwell = LinkedHashMap, Long>() var stable = 0 var last: Pair?

Two ways that got in: `outer_position` was falling back to a substitute whenever the extents were the placeholder, and every candidate is wrong in its own way — `event.position()` is frame-relative under a reparenting WM, `root_origin` is implemented through `frame_extents` and answers the placeholder too, and `gdk_window_get_origin` names the client rather than the frame, so anchoring one window against another then mixes two rectangles. The size still comes from the configure event, which is what fixes the 1x1 frame; the position is simply kept as it was. And a `Moved` carrying a position that is not the one the follow logic asked for was taken for the user dragging the window, so the offset it had just computed was replaced by one derived from an intermediate frame — latched, and preserved from then on. While a move is in flight those are ignored, bounded by the same echo budget as before so a move the platform never confirms cannot make the satellite deaf to a real drag. --- .../window/tao/SatelliteWindow.kt | 32 ++++++----- ...007-linux-outer-geometry-placeholder.patch | 54 +++++++++++-------- .../main/native/vendor/tao-patches/README.md | 2 +- .../tao/src/platform_impl/linux/window.rs | 46 +++++++++------- 4 files changed, 79 insertions(+), 55 deletions(-) diff --git a/decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/SatelliteWindow.kt b/decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/SatelliteWindow.kt index f5b9b88ad..4750d1dab 100644 --- a/decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/SatelliteWindow.kt +++ b/decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/SatelliteWindow.kt @@ -578,19 +578,25 @@ private class SatelliteAnchoring( captureOffset() return } - if (awaitingCommand && - closeEnough(xPx, commandedXPx) && - closeEnough(yPx, commandedYPx) - ) { - // Caught up with the last follow move. - awaitingCommand = false - inFlight = 0 - return - } - if (inFlight > 0) { - // Stale echo from an earlier follow move in the same drag burst. - inFlight-- - return + if (awaitingCommand) { + if (closeEnough(xPx, commandedXPx) && closeEnough(yPx, commandedYPx)) { + // Caught up with the last follow move. + awaitingCommand = false + inFlight = 0 + return + } + if (inFlight > 0) { + // Still travelling to where we put it.

On Windows a redraw request is now answered as the queued event it already is, which puts every window on the same priority; OS-driven repaints still arrive as RedrawRequested, and the JVM-side latch keeps one request per frame. A satellite created in the very frame its owner is being taken down never hears that owner's closing announcement, so Win32 and GTK destroy it along with the owner. The composable is still declared and its remembered window is dead: the palette stays open, floating and invisible for the rest of the session. It now rebuilds against whoever owns it at that point. A parent window is reported at the platform's cascade position until its own WindowState is applied, so a satellite anchored to that frame is placed beside a window that was never there — and the stale placement its own WindowState carries lands *after* the settle loop's correction. Satellites now wait for two identical parent frames before composing, and the settle loop re-asserts the anchored offset until it holds. Test side: awaitUntil takes an optional detail lambda read at timeout, and the load and monkey cases use it to name the window that starved or the palette that never came back. --- .../window/tao/SatelliteWindow.kt | 278 +++++++++++------- .../src/main/native/src/event_loop.rs | 34 ++- .../SatelliteWorkspaceMonkeyHeadfulCases.kt | 3 + .../tao/headful/TaoWindowTestHarness.kt | 7 +- .../tao/headful/WorkspaceLoadHeadfulCases.kt | 20 +- 5 files changed, 223 insertions(+), 119 deletions(-) diff --git a/decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/SatelliteWindow.kt b/decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/SatelliteWindow.kt index 4750d1dab..159f8c47e 100644 --- a/decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/SatelliteWindow.kt +++ b/decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/SatelliteWindow.kt @@ -7,6 +7,7 @@ import androidx.compose.runtime.CompositionLocalContext import androidx.compose.runtime.DisposableEffect import androidx.compose.runtime.LaunchedEffect import androidx.compose.runtime.getValue +import androidx.compose.runtime.key import androidx.compose.runtime.mutableStateOf import androidx.compose.runtime.remember import androidx.compose.runtime.rememberUpdatedState @@ -140,125 +141,149 @@ public fun ApplicationScope.SatelliteWindow( val parentPlaced = parentHasFrame(parent) if (!parentPlaced) return - // Resolved synchronously, before the native window exists, so - // DecoratedWindow's position effect applies it *before* show() — the same - // no-flash ordering DecoratedDialog relies on for its centring.

5ccfec799d5b61dac3f00550a2aeec6c3de6f4f2 Mon Sep 17 00:00:00 2001 From: "Elie G." Date: Fri, 4 Sep 2026 12:57:15 +0300 Subject: [PATCH 083/233] fix(tao): never hold key-event locks across PeekMessageW on Windows (#640) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit `PeekMessageW` delivers pending cross-thread *sent* messages inline: the kernel re-enters the window procedure through `KiUserCallbackDispatcher` before the peek returns. Two non-reentrant `parking_lot::Mutex`es were held across such a peek, so the nested dispatch deadlocked the event-loop thread against itself — it parked in `WaitOnAddress` and never pumped a message again, leaving the window permanently "Not Responding". - `event_loop.rs`: the keyboard callback held the global `KEY_EVENT_BUILDERS` map across `KeyEventBuilder::process_message`, which peeks. The builder is now taken out of the map for the duration and put back afterwards (only if the slot still exists, so a window dropped re-entrantly is not resurrected). Its map value became an `Option` slot to make that take/put-back possible. - `keyboard.rs`: the key-press and key-release arms held `LAYOUT_CACHE` across their peek, while every other arm — and `update_modifiers`, reached from any mouse or focus message — locks it too. The guard is now scoped to end before the peek and re-acquired after it. Reported as a freeze when moving a window between Windows 11 virtual desktops: that path is keyboard-triggered and makes the shell send messages to the window mid-peek.

The peek now happens in `ime::peek_commit_queued` before the lock is taken, and the result is passed in — mirroring upstream, where "IME character-pending detection happens before acquiring window state locks". Wider blast radius than #640: there only the keyboard arm took the lock, here nearly every arm does, so any nested message deadlocked. Upstream: tauri-apps/tao#1215. - `TaskbarCreated`: the window-state lock was held across `set_skip_taskbar`, which goes through `CoCreateInstance` + `ITaskbarList`. An STA COM call pumps the message queue while it waits, so the window procedure is re-entered. The flag is now read out before the call. Upstream: tauri-apps/tao#1264. `Imm32Source` carries the precomputed flag instead of peeking on demand; `ImeSource` is unchanged, so the IME state-machine tests keep driving the same sequences through their stub. --- .../src/platform_impl/windows/event_loop.rs | 23 +++++-- .../tao/src/platform_impl/windows/ime.rs | 65 ++++++++++++++----- 2 files changed, 68 insertions(+), 20 deletions(-) diff --git a/decorated-window-tao/src/main/native/vendor/tao/src/platform_impl/windows/event_loop.rs b/decorated-window-tao/src/main/native/vendor/tao/src/platform_impl/windows/event_loop.rs index 8473f42cc..3390e24fd 100644 --- a/decorated-window-tao/src/main/native/vendor/tao/src/platform_impl/windows/event_loop.rs +++ b/decorated-window-tao/src/main/native/vendor/tao/src/platform_impl/windows/event_loop.rs @@ -54,7 +54,7 @@ use crate::{ platform_impl::platform::{ dark_mode::try_window_theme, dpi::{become_dpi_aware, dpi_to_scale_factor, enable_non_client_dpi_scaling}, - ime::{is_msg_ime_related, ImeEvent}, + ime::{is_msg_ime_related, peek_commit_queued, ImeEvent}, keyboard::is_msg_keyboard_related, keyboard_layout::LAYOUT_CACHE, monitor::{self, MonitorHandle}, @@ -1033,11 +1033,20 @@ unsafe fn public_window_callback_inner( if !is_ime_related { return; } + // Peek the queue BEFORE taking the window-state lock. `process_message` + // used to do this peek itself, with the lock held, which deadlocks the + // event-loop thread against itself: `PeekMessageW` delivers pending + // cross-thread sent messages inline (the kernel re-enters this window + // procedure through `KiUserCallbackDispatcher`), and nearly every arm + // below locks the window state.

Two defects, both needed for the failure. The bridge decided whether it had a placement to leave from a single sample of `v1.placement` plus the native flags. AppKit clears `isZoomed` at the *start* of the un-zoom animation, so right after a toggle both read Floating while a queued `zoom:` has not landed yet. `leftPlacement` was therefore false, the bounds were applied to a window that was about to re-zoom, and `confirmBounds` — the whole point of which is to catch exactly that — was skipped because it is gated on the same flag. A placement applied within the last second is now its own reason to confirm. `confirmBounds` could not have recovered anyway. It returned as soon as the geometry matched, without ever asking whether a placement had come back, and its size check cannot detect one: a maximized window ignores v1's size, so `decorationInsets` derives the insets from a target that never landed (2560 outer - 820 target = 1740 dp of "decoration") and the subtraction reports sizeOk for any outer rectangle at all. It now treats a re-asserted placement as a failure to converge in its own right, tested before the geometry, and clears it by handing Floating back to v1 so the window composable's placement effect issues the single `zoom:` — the same "who issues the restore matters" rule the bounds path already follows, and the reason poking the native flag here would re-zoom. The case now passes in 1.9 s. Full headful suite on macOS: 205 run, 0 failed. Also give that wait a `detail` snapshot, since a bare "timed out" is what made this expensive to diagnose in the first place. --- .../window/tao/NucleusWindowV2Bridge.kt | 57 +++++++++++++++++-- .../tao/headful/WindowApiV2HeadfulCases.kt | 9 ++- 2 files changed, 59 insertions(+), 7 deletions(-) diff --git a/decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/NucleusWindowV2Bridge.kt b/decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/NucleusWindowV2Bridge.kt index 37b4d16e0..0b1ccb36b 100644 --- a/decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/NucleusWindowV2Bridge.kt +++ b/decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/NucleusWindowV2Bridge.kt @@ -147,9 +147,14 @@ internal fun BindNucleusWindowState( val latestV1 = v1 val latestNativeWindow by rememberUpdatedState(nativeWindow) LaunchedEffect(v2, v1) { + // When the last placement was handed to v1.

This brings macOS up to that level and pulls the shared policy into one file. Measured first: Ganesh already hands out 256 MiB by default, exactly the value the Windows host writes at attach. So that write was a no-op and the comment claiming it "forces purgeAsNeeded on every flush ... which is what keeps the steady state bounded at all" was wrong — Skia purges to fit its budget whether or not we set one. What reclaims is the purge. The comment is corrected rather than propagated. macOS gets the same mechanism, adapted to the backend: - the budget is anchored inside the same runOnRenderThread hop as makeMetal, since writing it purges to fit and so belongs on the owning thread; - purgeGpuResourceCache() submits the limit-toggle to the render executor instead of awaiting it — Metal has no current context, so none of the #514 foreign-context hazard applies here, but the context is thread-affine, and blocking the Tao main thread would park the drag behind the in-flight replay; - onResizeStreamAdvanced() purges every 250 ms while sizes stream and once more 500 ms after the last one, standing in for the WM_EXITSIZEMOVE macOS never sends. One deliberate divergence from Windows: the settle's System.gc() is gated on the burst having carried at least 8 resize events. Windows only sees WM_EXITSIZEMOVE after a real drag, but here every size change settles, including the single event a zoom, a snap or a programmatic resize produces, and a stop-the-world collection after each of those costs more than it returns.

Against that nil benefit sits a real cost — a full cache purge re-mints the glyph atlas and layer backings, and the GC is stop-the-world, both landing half a second after every resize, including the single event a zoom, a snap or a programmatic resize produces. Keep the in-drag periodic purge, which is free (every frame of a drag is re-rastering anyway) and bounds a long drag on a large display. Drop the settle timer, the GC nudge and the burst-count gate that tried to make the nudge affordable; with them go the two constants and the host scope they needed, so startRenderLoop goes back to its local scope.

Date: Fri, 4 Sep 2026 15:34:10 +0300 Subject: [PATCH 088/233] fix(application): keep window content on the UI applier (#636) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Port of 41266637 to 2.6, extended to the branch's own window openers. The window and dialog openers had their composition target inferred, so a single non-UI-targeted composable called in the `nucleusApplication` scope (the Compose compiler bakes `@ComposableTarget` onto any unmarked factory forwarding a target-marked content lambda) reclassified the whole scope — nested windows included — and every `@UiComposable` call in it warned, which is fatal under `-Werror`. Declare each opener `@ComposableOpenTarget(-1)` with `@UiComposable` content lambdas, the way Compose Desktop's own `Window`/`Dialog` are open: they are callable from any applier and always compose UI content in the new window's own composition, so neither direction of the applier leak survives. Covers `DecoratedWindow`/`DecoratedDialog`, the `NucleusWindowHost` / `NucleusDialogHost` interfaces with their default implementations, `HostedWindow`/`HostedDialog`, `SatelliteWindow`, `Satellite`, `Tab`, and Tao's equivalents plus `TaoStandalonePopup`. `TabWindows`, the v2 `DecoratedWindow`/`DecoratedDialog` and `DragGhostWindow` already infer the same scheme (`[_[UiComposable]]`), as do the Material/Jewel wrappers. Once a declaration carries an explicit target, inference stops for all of it: every composable lambda parameter needs the annotation, not just `content`. `Satellite`'s `floatingContentWrapper` was the one case where leaving one unmarked kept dragging the caller's applier into the satellite content. `COMPOSE_APPLIER_CALL_MISMATCH` is only a warning, so both test compilations escalate it to an error and a fixture per module compiles the reported shape (non-UI factory in the application scope, UI content in every window). --- decorated-window-tao/build.gradle.kts | 7 ++ .../window/tao/DecoratedDialog.kt | 12 +++- .../window/tao/DecoratedWindowComposable.kt | 12 +++- .../nucleusframework/window/tao/Satellite.kt | 18 ++++- .../window/tao/SatelliteWindow.kt | 12 +++- .../nucleusframework/window/tao/TabWindows.kt | 12 +++- .../window/tao/TaoStandalonePopup.kt | 12 +++- .../tao/ComposableTargetIsolationFixture.kt | 65 +++++++++++++++++++ nucleus-application/build.gradle.kts | 7 ++ nucleus-application/detekt-baseline.xml | 2 - .../application/DecoratedDialog.kt | 14 +++- .../application/DecoratedWindow.kt | 14 +++- .../application/NucleusWindowHost.kt | 35 ++++++++-- .../nucleusframework/application/Satellite.kt | 19 ++++-- .../application/SatelliteWindow.kt | 15 ++++- .../dev/nucleusframework/application/Tab.kt | 15 ++++- .../ComposableTargetIsolationFixture.kt | 51 +++++++++++++++ 17 files changed, 291 insertions(+), 31 deletions(-) create mode 100644 decorated-window-tao/src/test/kotlin/dev/nucleusframework/window/tao/ComposableTargetIsolationFixture.kt create mode 100644 nucleus-application/src/test/kotlin/dev/nucleusframework/application/ComposableTargetIsolationFixture.kt diff --git a/decorated-window-tao/build.gradle.kts b/decorated-window-tao/build.gradle.kts index 34e8a2ef5..b2fe69864 100644 --- a/decorated-window-tao/build.gradle.kts +++ b/decorated-window-tao/build.gradle.kts @@ -52,6 +52,13 @@ kotlin { } } +// #636 regression guard: the Compose applier-mismatch diagnostic is a warning, +// so ComposableTargetIsolationFixture would silently rot.

Date: Sat, 5 Sep 2026 20:31:36 +0300 Subject: [PATCH 089/233] fix(tao): place native popup layers against the screen, not the window (#569) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit `nativePopupLayers` made every Compose `Popup` a real OS window, but the *decision* of where to put it stayed window-rooted, in two stacked ways. The layers each built a work-area-sized `WindowInfo` so a popup could lay out and flip against the display — and then `setContent` replayed the owner window's composition locals over it, so `Popup.skiko.kt` read the window's `containerSize` and clipped every popup back inside the window. The intended design had never taken effect. The layers now re-provide `LocalWindowInfo` inside the replayed locals. With that in force the box is screen-sized but still rooted at the window's content origin, so a `DropdownMenu` in a window near the bottom of the display did not flip up — Compose saw a whole work area of room below the anchor — and walked off the screen. Each layer now clamps its native frame into the work area of the display it lands on, at the single point where it pushes that frame: `popupScreenClampOffset`, fed the owner's content origin on screen plus every display's work area. Only the native frame moves; `boundsInWindow` stays what Compose believes, which is what hit-testing and the surface content are expressed in. Re-clamped on every push, so an open popup survives an owner drag, across monitors included. Dialogs go through the same layers but must not follow the display: `Dialog.skiko.kt` places at `containerSize.center`, so a window-owned dialog centred on the screen would sit visibly off-centre and drift as the window moved. Layers report the window size for dialogs and the work area for popups, discriminated on `scrimColor` — only `Dialog.skiko.kt` writes it, from `DialogAppearanceController.properties` during `DialogLayout`'s composition, before `layer.Content { }` reads the container. macOS needs the NSView's own origin on screen (a native title bar sits between it and the window frame), hence `nativeGetContentRect`. Wayland reports no geometry and is left unclamped: a popup there is a `wl_subsurface` placed relative to the parent, with no global position. Also exposes `nativePopupLayers` on `JewelDecoratedWindow`, which had no such parameter at all — Jewel apps could not opt in. Jewel needs nothing further: `DefaultPopupRenderer` delegates to `androidx.compose.ui.window.Popup`, so its combo boxes, menus and tooltips flow through the fixed layers. Tests: 18 unit cases on the clamp geometry, and 13 headful cases driving real windows parked at real work-area edges — including one that reads the popup HWND's rect back through Win32 and asserts it matches the reported frame to the pixel, and two that pin the dialog contract. A new "Popups" tab in nucleus-demo parks the window at any corner and opens menus anchored at each window edge. --- .../window/jewel/JewelDecoratedWindow.kt | 12 + .../tao/ffi/NativeTaoMacOsDecoBridge.kt | 15 + .../window/tao/popup/PopupScreenClamp.kt | 70 ++ .../window/tao/popup/PopupScreenGeometry.kt | 47 ++ .../window/tao/popup/TaoPopupDiagnostics.kt | 73 ++ .../window/tao/popup/TaoPopupHost.kt | 15 + .../window/tao/popup/TaoPopupHostLinux.kt | 11 + .../window/tao/popup/TaoPopupHostWindows.kt | 8 + .../window/tao/popup/TaoPopupSceneLayer.kt | 100 ++- .../tao/popup/TaoPopupSceneLayerLinux.kt | 95 ++- .../tao/popup/TaoPopupSceneLayerWindows.kt | 99 ++- .../window/tao/scene/TaoComposeSceneHost.kt | 26 + .../tao/scene/TaoComposeSceneHostLinux.kt | 14 + .../tao/scene/TaoComposeSceneHostWindows.kt | 30 + .../src/main/native/macos/decoration.m | 29 + .../tao/TaoSceneTestBatteryDriftTest.kt | 2 + .../NativePopupPlacementHeadfulCases.kt | 664 ++++++++++++++++++ .../tao/headful/TaoHeadfulTestSuiteMain.kt | 1 + .../window/tao/popup/PopupScreenClampTest.kt | 243 +++++++ .../src/main/kotlin/jewelsample/Main.kt | 7 + .../src/main/kotlin/com/example/demo/Main.kt | 4 +- .../com/example/demo/PopupPlacementScreen.kt | 272 +++++++ 22 files changed, 1816 insertions(+), 21 deletions(-) create mode 100644 decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/popup/PopupScreenClamp.kt create mode 100644 decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/popup/PopupScreenGeometry.kt create mode 100644 decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/popup/TaoPopupDiagnostics.kt create mode 100644 decorated-window-tao/src/test/kotlin/dev/nucleusframework/window/tao/headful/NativePopupPlacementHeadfulCases.kt create mode 100644 decorated-window-tao/src/test/kotlin/dev/nucleusframework/window/tao/popup/PopupScreenClampTest.kt create mode 100644 examples/nucleus-demo/src/main/kotlin/com/example/demo/PopupPlacementScreen.kt diff --git a/decorated-window-jewel/src/main/kotlin/dev/nucleusframework/window/jewel/JewelDecoratedWindow.kt b/decorated-window-jewel/src/main/kotlin/dev/nucleusframework/window/jewel/JewelDecoratedWindow.kt index 112400a4f..7add30d0a 100644 --- a/decorated-window-jewel/src/main/kotlin/dev/nucleusframework/window/jewel/JewelDecoratedWindow.kt +++ b/decorated-window-jewel/src/main/kotlin/dev/nucleusframework/window/jewel/JewelDecoratedWindow.kt @@ -66,6 +66,17 @@ public fun NucleusApplicationScope.JewelDecoratedWindow( // native Wayland session, for the window management Wayland has no protocol // for (stacking, positioning, workspace stickiness).

Date: Sat, 5 Sep 2026 21:57:41 +0300 Subject: [PATCH 090/233] fix(tao): make native popup layer dialogs look like in-scene ones (#569) A Compose Dialog opened through nativePopupLayers had no scrim, clipped its shadow and its appearance animation at the layout edge, slid diagonally towards the display centre while scaling in, and stayed put when the window was resized. - Scrims: the owner window paints every layer's scrim after its content and each layer paints the scrims of the layers above it (PopupScrimRegistry, TaoSceneBundle.renderOverlay). A scrim change marks the owner scene visually dirty, so the Windows clean-frame present skip no longer eats the fade. - Draw margin: the native surface extends 32 dp past boundsInWindow so shadows and the 10 dp slide-in are not clipped. Compose 1.12 renders a scene as one RenderNode drawable with unbounded bounds, so the R-tree cull-rect measurement upstream uses reports the whole canvas; a constant margin replaces it. The screen clamp is decided on the content rect; the interactive region stays the content (Windows content rect, macOS region hit-test, Linux press filter). - Dialog scene size: a dialog's root Layout fills the layer scene's constraints and carries the appearance GraphicsLayer, so its scale pivots on the scene centre. Dialog layers now run their inner scene at the owner window size, popups keep the work area. - Resize: the dialog container size is read from the owner's snapshot-backed WindowInfo, so the dialog re-centres when the window is resized. DialogAppearanceHeadfulCases films both layer modes with java.awt.Robot and compares slide-in, scrim ramp and settle time; PopupFrameRecord gains the content frame next to the inflated native frame. --- decorated-window-tao/build.gradle.kts | 3 + .../window/tao/popup/PopupDrawInflate.kt | 43 ++ .../window/tao/popup/PopupScrimRegistry.kt | 113 +++++ .../window/tao/popup/TaoPopupDiagnostics.kt | 9 +- .../window/tao/popup/TaoPopupHost.kt | 17 + .../window/tao/popup/TaoPopupHostLinux.kt | 7 + .../window/tao/popup/TaoPopupHostWindows.kt | 7 + .../window/tao/popup/TaoPopupSceneLayer.kt | 219 ++++++---- .../tao/popup/TaoPopupSceneLayerLinux.kt | 95 ++++- .../tao/popup/TaoPopupSceneLayerWindows.kt | 79 +++- .../window/tao/scene/MetalSceneRenderer.kt | 10 + .../window/tao/scene/TaoComposeSceneHost.kt | 45 +- .../tao/scene/TaoComposeSceneHostLinux.kt | 42 +- .../tao/scene/TaoComposeSceneHostWindows.kt | 43 +- .../window/tao/scene/TaoSceneBundle.kt | 10 + .../tao/TaoSceneTestBatteryDriftTest.kt | 8 + .../headful/DialogAppearanceHeadfulCases.kt | 403 ++++++++++++++++++ .../NativePopupPlacementHeadfulCases.kt | 85 +++- .../tao/headful/TaoHeadfulTestSuiteMain.kt | 1 + .../window/tao/popup/PopupDrawInflateTest.kt | 45 ++ .../tao/popup/PopupScrimRegistryTest.kt | 148 +++++++ 21 files changed, 1287 insertions(+), 145 deletions(-) create mode 100644 decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/popup/PopupDrawInflate.kt create mode 100644 decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/popup/PopupScrimRegistry.kt create mode 100644 decorated-window-tao/src/test/kotlin/dev/nucleusframework/window/tao/headful/DialogAppearanceHeadfulCases.kt create mode 100644 decorated-window-tao/src/test/kotlin/dev/nucleusframework/window/tao/popup/PopupDrawInflateTest.kt create mode 100644 decorated-window-tao/src/test/kotlin/dev/nucleusframework/window/tao/popup/PopupScrimRegistryTest.kt diff --git a/decorated-window-tao/build.gradle.kts b/decorated-window-tao/build.gradle.kts index b2fe69864..a24f4c6ec 100644 --- a/decorated-window-tao/build.gradle.kts +++ b/decorated-window-tao/build.gradle.kts @@ -168,6 +168,9 @@ val taoHeadfulTest by tasks.registering(JavaExec::class) { System.getProperty("nucleus.tao.headful.monkeySeed")?.let { systemProperty("nucleus.tao.headful.monkeySeed", it) } + System.getProperties().stringPropertyNames().filter { it.startsWith("nucleus.dialog.appearance.") }.forEach { + systemProperty(it, System.getProperty(it)) + } System.getProperty("nucleus.issue576.samples")?.let { systemProperty("nucleus.issue576.samples", it) } diff --git a/decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/popup/PopupDrawInflate.kt b/decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/popup/PopupDrawInflate.kt new file mode 100644 index 000000000..d83d72641 --- /dev/null +++ b/decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/popup/PopupDrawInflate.kt @@ -0,0 +1,43 @@ +package dev.nucleusframework.window.tao.popup + +import androidx.compose.ui.unit.IntRect +import kotlin.math.ceil + +/** + * Margin, in dp, that a native popup layer's surface extends past + * `boundsInWindow` on every side, so that what Compose draws outside the + * layout rectangle is not clipped at the surface edge. + * + * `boundsInWindow` is the popup's *layout* rectangle.

Date: Sat, 5 Sep 2026 22:08:05 +0300 Subject: [PATCH 091/233] test(tao): film the dialog's disappearance too, under a heavier scene MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The appearance film now also records the hide animation and counts grabs that repeat the previous frame during either animation — dropped frames show up as a stall count the native layer must not exceed. The owner window carries forty rows of text so its per-frame present costs something. The first-visible check is one-sided: the native surface legitimately shows its first frame before the owner's next present. --- .../headful/DialogAppearanceHeadfulCases.kt | 110 ++++++++++++++++-- 1 file changed, 102 insertions(+), 8 deletions(-) diff --git a/decorated-window-tao/src/test/kotlin/dev/nucleusframework/window/tao/headful/DialogAppearanceHeadfulCases.kt b/decorated-window-tao/src/test/kotlin/dev/nucleusframework/window/tao/headful/DialogAppearanceHeadfulCases.kt index 0eeb34ff8..a2271732c 100644 --- a/decorated-window-tao/src/test/kotlin/dev/nucleusframework/window/tao/headful/DialogAppearanceHeadfulCases.kt +++ b/decorated-window-tao/src/test/kotlin/dev/nucleusframework/window/tao/headful/DialogAppearanceHeadfulCases.kt @@ -60,9 +60,61 @@ internal object DialogAppearanceHeadfulCases { ) internal class Curve( - val samples: List, + val all: List, + /** When the dialog was asked to close; samples from here on film the disappearance. */ + val hideAtMs: Long, ) { + /** The appearance: from the show request until the hide request. */ + val samples: List get() = all.filter { it.tMs < hideAtMs } + + /** The disappearance: from the hide request on. */ + val hiding: List get() = all.filter { it.tMs >= hideAtMs } val visible: List get() = samples.filter { it.dialogTop != null } + + /** First moment after the hide request where the dialog started to change. */ + val hideStartMs: Long?

Date: Sat, 5 Sep 2026 22:22:28 +0300 Subject: [PATCH 092/233] fix(tao): keep a native dialog's surface where the dialog was while it fades out (#569) Dialog.skiko.kt's disappearance swaps the layer's content for an empty Layout that replays the recorded picture, and Compose then reports a zero-size boundsInWindow at the window centre for the whole fade-out. An in-scene layer draws into the window canvas and does not care; the native surface followed the bounds and shrank to a 32 dp square around a point, so a closing dialog collapsed and vanished instead of fading out. Each layer now sizes and places its surface on the last non-empty bounds. The appearance film gains the Material 3 AlertDialog nucleus-demo opens, a warm-up before filming, a duration-based comparison, and the smallest height the dialog spanned while fading out. --- decorated-window-tao/build.gradle.kts | 2 + .../window/tao/popup/TaoPopupSceneLayer.kt | 26 +++- .../tao/popup/TaoPopupSceneLayerLinux.kt | 22 +++- .../tao/popup/TaoPopupSceneLayerWindows.kt | 30 +++-- .../headful/DialogAppearanceHeadfulCases.kt | 124 ++++++++++++++++-- 5 files changed, 169 insertions(+), 35 deletions(-) diff --git a/decorated-window-tao/build.gradle.kts b/decorated-window-tao/build.gradle.kts index a24f4c6ec..fc4cca49a 100644 --- a/decorated-window-tao/build.gradle.kts +++ b/decorated-window-tao/build.gradle.kts @@ -39,6 +39,8 @@ dependencies { testImplementation(kotlin("test")) // Skiko native runtime for the opt-in real-window smoke test testImplementation(compose.desktop.currentOs) + // The Material 3 AlertDialog the headful appearance film compares against nucleus-demo + testImplementation(libs.compose.material3) } java { diff --git a/decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/popup/TaoPopupSceneLayer.kt b/decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/popup/TaoPopupSceneLayer.kt index 082f007f2..fcec41cde 100644 --- a/decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/popup/TaoPopupSceneLayer.kt +++ b/decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/popup/TaoPopupSceneLayer.kt @@ -155,6 +155,17 @@ internal class TaoPopupSceneLayer( */ private var drawBounds: IntRect = IntRect.Zero + /** + * The last non-empty [_bounds]: what the native surface is sized and placed + * on. `Dialog.skiko.kt`'s disappearance swaps the layer's content for an + * empty `Layout` that only replays the recorded picture, so Compose reports + * a zero-size `boundsInWindow` at the window centre for the whole fade-out. + * An in-scene layer does not care — it draws into the window canvas — but + * this surface must keep covering where the dialog was, or the fade-out + * shows as a square of margin around a point. + */ + private var contentBounds: IntRect = IntRect.Zero + /** * Panel created at parent-window-size offscreen so the inner scene * has real layout constraints, while the user doesn't see a 1×1 @@ -425,6 +436,7 @@ internal class TaoPopupSceneLayer( get() = _bounds set(value) { _bounds = value + if (!value.isEmpty) contentBounds = value updateNativeFrame() host.requestRedraw() } @@ -444,10 +456,10 @@ internal class TaoPopupSceneLayer( * what the scene draws in and what [scenePosition] maps pointers back to. */ private fun updateNativeFrame() { -

charset=UTF-8 Content-Transfer-Encoding: 8bit The Windows and Linux context menu flyouts drew inside the window's render target whenever the window ran without nativePopupLayers, so a menu opened near an edge was clipped by the window like any in-scene popup. An OS-looking menu has to leave the window like the menus it imitates, and the application's choice for its other popups must not decide that. nativePopupLayers is a whole-scene switch (platform vs canvas layers), so a per-popup opt-in needs the seam Compose 1.12 actually uses: Popup picks its layer through LocalComposeSceneContext. A friend-package Java accessor reaches that internal local without reflection; NativePopupLayers { } then provides, for its subtree only, the window scene's own context with createLayer routed to the window's native popup layer factory — the same factory attach() uses when nativePopupLayers is on. The context menu representation wraps the Windows and Linux flyouts in it; macOS stays on NSMenu. --- .../window/jewel/JewelDecoratedWindow.kt | 2 + .../material2/MaterialDecoratedWindow.kt | 2 + .../material/MaterialDecoratedWindow.kt | 2 + .../api/decorated-window-tao.api | 8 + .../scene/TaoComposeSceneContextAccess.java | 31 ++++ .../window/tao/DecoratedWindow.kt | 15 ++ .../window/tao/NativePopupLayers.kt | 78 ++++++++ .../tao/scene/TaoComposeSceneContext.kt | 20 ++- .../window/tao/scene/TaoComposeSceneHost.kt | 36 ++-- .../tao/scene/TaoComposeSceneHostLinux.kt | 36 ++-- .../tao/scene/TaoComposeSceneHostWindows.kt | 33 ++-- .../window/tao/NativePopupLayersTest.kt | 170 ++++++++++++++++++ .../src/main/kotlin/com/example/demo/Main.kt | 2 +- .../application/DecoratedWindow.kt | 6 +- .../NativeContextMenuRepresentation.kt | 12 +- 15 files changed, 402 insertions(+), 51 deletions(-) create mode 100644 decorated-window-tao/src/main/java/androidx/compose/ui/scene/TaoComposeSceneContextAccess.java create mode 100644 decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/NativePopupLayers.kt create mode 100644 decorated-window-tao/src/test/kotlin/dev/nucleusframework/window/tao/NativePopupLayersTest.kt diff --git a/decorated-window-jewel/src/main/kotlin/dev/nucleusframework/window/jewel/JewelDecoratedWindow.kt b/decorated-window-jewel/src/main/kotlin/dev/nucleusframework/window/jewel/JewelDecoratedWindow.kt index 7add30d0a..fa791f844 100644 --- a/decorated-window-jewel/src/main/kotlin/dev/nucleusframework/window/jewel/JewelDecoratedWindow.kt +++ b/decorated-window-jewel/src/main/kotlin/dev/nucleusframework/window/jewel/JewelDecoratedWindow.kt @@ -41,6 +41,8 @@ public fun NucleusApplicationScope.JewelDecoratedWindow( popupFor: NucleusWindow?

A menu opened near the bottom of the screen was cut off. On native Wayland a client cannot know where its own window is, so it cannot keep a popup on screen by itself — the X11 clamp of #569 has nothing to work with there. The popup layer now maps as an xdg_popup instead of a wl_subsurface and lets the compositor place it: it flips above the pointer when there is no room below and slides along an edge, which is what GTK's own menus do. The tao patch carries the anchor point, the surface size and the shadow margins in one request, because GDK builds the positioner from the window's geometry as it stands at map time — a popup still sized 1x1 there asks the compositor to constrain a 1x1 rectangle and is never flipped. One popup per parent takes that path (an xdg_popup must be its parent's topmost popup); a dialog keeps the subsurface, since it belongs to its window rather than to the display. A second right click only closed the menu instead of moving it. The press that dismisses a popup is delivered to the scene in the same turn as the dismissal, so Compose's contextMenuOpenDetector — disabled while the menu is open — was still disabled when the press arrived, and the press did nothing. The host now recomposes and re-lays-out the scene between the two, so the detector is listening again by the time it sees the press. The menu also appeared a beat late: the layer painted its first frame only on the owner window's next redraw, though that first render is what measures the content and puts the popup on screen at all. It renders as soon as its GPU side is up. Measured against the fixture's trace, press to first present is now 40 ms steady, 108 ms for the first menu of a session. --- .../nucleusframework/window/tao/TaoWindow.kt | 49 +- .../window/tao/ffi/NativeTaoBridge.kt | 18 + .../window/tao/popup/TaoPopupDiagnostics.kt | 11 + .../window/tao/popup/TaoPopupHostLinux.kt | 13 + .../tao/popup/TaoPopupSceneLayerLinux.kt | 88 +++- .../tao/scene/TaoComposeSceneHostLinux.kt | 44 ++ .../window/tao/scene/TaoSceneBundle.kt | 20 + .../src/main/native/src/event_loop.rs | 38 ++ .../src/main/native/src/events.rs | 13 + .../src/main/native/src/window_jni.rs | 28 ++ .../native/vendor/tao/src/platform/unix.rs | 9 + .../tao/src/platform_impl/linux/event_loop.rs | 81 +++ .../tao/src/platform_impl/linux/window.rs | 39 ++ .../window/tao/TaoSceneTestBattery.kt | 12 + .../tao/TaoSceneTestBatteryDriftTest.kt | 1 + nucleus-application/build.gradle.kts | 22 + .../contextmenu/ContextMenuE2EMain.kt | 159 ++++++ scripts/context-menu-wayland-e2e.py | 476 ++++++++++++++++++ 18 files changed, 1116 insertions(+), 5 deletions(-) create mode 100644 nucleus-application/src/test/kotlin/dev/nucleusframework/application/contextmenu/ContextMenuE2EMain.kt create mode 100755 scripts/context-menu-wayland-e2e.py diff --git a/decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/TaoWindow.kt b/decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/TaoWindow.kt index 3c2e57938..bb8ac2435 100644 --- a/decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/TaoWindow.kt +++ b/decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/TaoWindow.kt @@ -17,6 +17,7 @@ import java.util.concurrent.ConcurrentHashMap import java.util.concurrent.CopyOnWriteArrayList import java.util.concurrent.atomic.AtomicBoolean import java.util.logging.Logger +import kotlin.math.roundToInt /** * Phase 2 handle to a window owned by the Tao event loop. @@ -928,6 +929,52 @@ public class TaoWindow internal constructor( NativeTaoBridge.nativeSetOuterPosition(handle, x, y) } + /** + * Linux native Wayland only, for a popup overlay (`openWindow(popupOf = …)`): + * anchors the popup's content at a point of the parent's content area + * through GDK's `move_to_rect`, so it maps as an `xdg_popup` the compositor + * keeps on screen — flipped above the point when there is no room below, + * slid along an edge — instead of a `wl_subsurface` the compositor cannot + * constrain.

Compose desktop multiplies those alphas by its fixed elevation factors (0.039 ambient, 0.19 spot), so the menu on GNOME darkened the pixels next to it by about 1 % — measured on the E2E screenshots — and read as having no shadow at all. An elevation shadow also cannot reproduce a CSS box-shadow, which is how GTK, Breeze and Fluent all describe theirs. The themes now carry those declarations as box-shadow layers (offset, blur, spread, colour), drawn as the menu's rounded rectangle under a Gaussian mask with the CSS standard deviation of half the blur radius: libadwaita's _popovers.scss for Adwaita, Breeze's ShadowLarge for KDE, Fluent 2's shadow16 token for Windows. On the nested GNOME Shell the bottom edge now darkens the backdrop by about 10 %, tapering over 17 px, as the GTK menus next to it do. --- .../contextmenu/AdwaitaContextMenu.kt | 17 +++- .../contextmenu/BreezeContextMenu.kt | 19 ++++- .../contextmenu/ContextMenuFlyout.kt | 80 ++++++++++++++++--- .../contextmenu/FluentContextMenu.kt | 23 +++++- 4 files changed, 119 insertions(+), 20 deletions(-) diff --git a/nucleus-application/src/main/kotlin/dev/nucleusframework/application/contextmenu/AdwaitaContextMenu.kt b/nucleus-application/src/main/kotlin/dev/nucleusframework/application/contextmenu/AdwaitaContextMenu.kt index 38c59fd3d..b7fce31f0 100644 --- a/nucleus-application/src/main/kotlin/dev/nucleusframework/application/contextmenu/AdwaitaContextMenu.kt +++ b/nucleus-application/src/main/kotlin/dev/nucleusframework/application/contextmenu/AdwaitaContextMenu.kt @@ -30,10 +30,8 @@ internal val AdwaitaMenuTheme = separatorPadding = PaddingValues(vertical = 6.dp), iconSize = 16.dp, iconGap = 6.dp, - shadowElevation = 8.dp, shadowPad = 16.dp, - ambientShadow = Color.Black.copy(alpha = 0.09f), - spotShadow = Color.Black.copy(alpha = 0.05f), + shadows = { AdwaitaMenuShadows }, showIcons = false, shortcutGap = 24.dp, shortcutSize = 14.sp, @@ -42,6 +40,19 @@ internal val AdwaitaMenuTheme = glyph = { null }, ) +/** + * `popover > contents { box-shadow: ... }` in libadwaita's `_popovers.scss`: + * `0 0 0 1px RGB(0 0 0 / 5%)`, `0 1px 5px 1px RGB(0 0 0 / 9%)`, + * `0 2px 14px 3px RGB(0 0 0 / 5%)`.

The margin a native popup layer's surface carries past `boundsInWindow` is transparent, but on Linux it is still the popup's window as far as the display server is concerned, and the layer swallowed everything that landed there: a click on a button 20 px beside an open menu closed the menu and never pressed the button, and hovering past the menu's edge froze the owner's hover state. Windows and macOS get the pass-through from the OS, which is handed the *content* rect. GTK's own input shaping does not take on a popup toplevel — the region reaches GDK and the X window keeps its full input shape — so the layer routes the event to the owner itself (`TaoPopupHostLinux.forwardMarginPointer`), and only while the point is over the owner's content: a press over another application is not ours to deliver. The press path is the one an owner press already takes, dismissal and mid-turn recompose included, now shared as `dismissPopupsBeforePress`. `NativePopupMarginInputHeadfulCases` drives a real pointer with `Robot` against a real popup and asserts on what the owner window's scene received — including a case with no popup open, without which "the owner saw nothing" would be as consistent with a broken driver as with a swallowed press. The macOS layer recorded its picture with a cull rect rooted at the picture origin while the scene draws in owner-window coordinates, so the rect the replay matrix maps lands off the drawable. Skia unrolls a one-op picture and never consults the rect, and a Compose scene is exactly one op, so a bare popup survived it; a popup dimmed by a dialog above it does not — the scrims go into the same picture and the whole frame is quick-rejected. `MacPopupPictureCullTest` runs the layer's frame against a real scene through the production record and replay paths and reads the pixels back. A compositor-placed popup (`xdg_popup`) that re-measured after it was mapped resized its EGL buffer while the `xdg_surface` geometry stayed at the anchored size — the buffer/geometry disagreement of #502. GDK positions a popup once, so the layer re-maps instead: hide, re-anchor at the new size, show. Also: closing a layer that was still dimming left the owner window dark until an unrelated invalidation, because `PopupScrimRegistry.unregister` removed the entry without reporting the change; the popup screen clamp read `TaoMonitors.all`, which invents a 1920x1080 monitor at the origin when the platform names none, and would have dragged a popup onto a display that does not exist — it asks `reported` now, and treats empty as "no geometry"; and nucleus-demo was missing a trailing comma, which failed `ktlintCheck` and took the whole `tao-headful` job down with it. --- .../window/tao/TaoMonitors.kt | 19 +- .../window/tao/popup/PopupDrawInflate.kt | 29 ++ .../window/tao/popup/PopupScrimRegistry.kt | 9 +- .../window/tao/popup/TaoPopupDiagnostics.kt | 11 + .../window/tao/popup/TaoPopupHostLinux.kt | 27 ++ .../window/tao/popup/TaoPopupSceneLayer.kt | 2 +- .../tao/popup/TaoPopupSceneLayerLinux.kt | 67 ++- .../window/tao/scene/MetalSceneRenderer.kt | 33 +- .../window/tao/scene/TaoComposeSceneHost.kt | 5 +- .../tao/scene/TaoComposeSceneHostLinux.kt | 67 ++- .../tao/scene/TaoComposeSceneHostWindows.kt | 5 +- .../window/tao/TaoMonitorsTest.kt | 29 ++ .../window/tao/TaoSceneTestBattery.kt | 16 + .../tao/TaoSceneTestBatteryDriftTest.kt | 5 +- .../NativePopupMarginInputHeadfulCases.kt | 383 ++++++++++++++++++ .../tao/headful/TaoHeadfulTestSuiteMain.kt | 1 + .../tao/popup/MacPopupPictureCullTest.kt | 220 ++++++++++ .../window/tao/popup/PopupDrawInflateTest.kt | 14 + .../tao/popup/PopupScrimRegistryTest.kt | 27 ++ .../window/tao/scene/TaoSceneTestHarness.kt | 32 +- .../src/main/kotlin/com/example/demo/Main.kt | 2 +- 21 files changed, 951 insertions(+), 52 deletions(-) create mode 100644 decorated-window-tao/src/test/kotlin/dev/nucleusframework/window/tao/headful/NativePopupMarginInputHeadfulCases.kt create mode 100644 decorated-window-tao/src/test/kotlin/dev/nucleusframework/window/tao/popup/MacPopupPictureCullTest.kt diff --git a/decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/TaoMonitors.kt b/decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/TaoMonitors.kt index 18555df5d..de0f3068f 100644 --- a/decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/TaoMonitors.kt +++ b/decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/TaoMonitors.kt @@ -126,7 +126,21 @@ public object TaoMonitors { * display reachable from a realized window; `null` falls back to the * default GDK display.

Material 3 was not, and the first case that reaches an `AlertDialog` throws `NoClassDefFoundError: androidx/compose/material3/MaterialThemeKt` **on the Tao main thread**, which closes the loop and fails the whole `test-graalvm` job on all three platforms. The configuration now extends `testImplementation`, so a dependency added to the suites reaches the image without being repeated — reproduced and verified on the JVM (`:examples:tao-native-test:run --args=headful`), which shares the classpath. While the film cases were finally running, three things they had never been green on: - Their content is composed into a `ColumnScope` next to the harness's default `fillMaxSize` background, so it was laid out at zero height: the forty rows of text that exist to make the owner's per-frame present cost something rendered nowhere. `paintDefaultBackground = false`. - The grabber started *before* the warm-up and spent its whole frame budget on it, leaving the curve with nothing after the timestamp it measures from — reported as "the dialog never showed up on screen". - One capture session covered both halves, so the appearance consumed the budget and the disappearance got no frames at all, which is what the comparison cases were failing on. Each half films in its own session now, within the same total budget. Under Xvfb + openbox the `appearance` series goes from 6 failures to 0. The `native popup layer matches the in-scene layer` comparison is borderline there (slide-in measured 15 px vs 10 px against a 4 px tolerance) because a 6 ms sample period is coarse for a 10 dp slide; the tolerances are left as calibrated. Not addressed: `graphicsLayer translation filmed — native popup layer` hangs on Linux, which is what makes that leg reach the 900 s watchdog. It draws a `GraphicsLayer` created from the *owner window's* `GraphicsContext` inside the popup's own GL context, with alpha forcing the saveLayer path; the in-scene variant of the same case passes. Pre-existing and its own investigation. --- decorated-window-tao/build.gradle.kts | 7 +++ .../headful/DialogAppearanceHeadfulCases.kt | 46 +++++++++++++++---- examples/tao-native-test/build.gradle.kts | 7 +-- 3 files changed, 48 insertions(+), 12 deletions(-) diff --git a/decorated-window-tao/build.gradle.kts b/decorated-window-tao/build.gradle.kts index fc4cca49a..05813c399 100644 --- a/decorated-window-tao/build.gradle.kts +++ b/decorated-window-tao/build.gradle.kts @@ -103,9 +103,16 @@ val taoTestClassesJar by tasks.registering(Jar::class) { from(sourceSets.test.get().output) } +// Consumers get the compiled test classes *and* what those classes need at run +// time.

The purge is armed in onResized but performed in the render pass. That is not a detail: onResized runs on the event-loop thread with no EGL context bound and the swap thread may be holding ours for its eglSwapBuffers, while the render pass is the one point where this host's context is current on this thread. It also lands right after applyPendingNativeResize has closed the previous size's Surface and BackendRenderTarget, which is exactly when their backing memory is unlocked and the toggle has something to return. Unlike macOS, the Linux resize path IS where the memory sits. On a 60-step storm, then a second storm shrinking back through the same sizes (NVIDIA graphics memory for the process, native Wayland / GNOME): without purge 13 MB -> 106 MB -> 114 MB with purge 13 MB -> 71 MB -> 27 MB Without the purge the footprint ratchets: the second storm revisits sizes the first already paid for and still grows, because nothing ever releases the scratch of a size no frame will ask for again. With it the footprint tracks the current window instead of the high-water mark of every size ever seen. Same shape on the X11 attach path (112 MB -> 23 MB). Frame throughput is unchanged in both regimes (~1050 frames per 1000 ms on Wayland, ~93 on the vsync-paced X11 path), so the reclaim costs no frames. No settle purge and no System.gc() nudge, for the reason macOS has none: GTK offers no drag-end signal, and a timer standing in for one buys a stop-the-world collection after every zoom, snap and programmatic resize.

Alternating click storms, a right click on the embed, a resize storm (discrete, burst, animated, interactive corner drag with the real pointer) and a 150-action random walk, each driven both by in-process injection and by the AWT Robot. Invariants: Compose keeps counting clicks, one keyboard owner at a time, a typed letter and a caret key land where the focus says, the I-beam is requested and kept over the field, the embed sits on its Compose slot, no probe leaks, the main dispatcher keeps answering. - TextureViewMonkeyHeadfulCases: four TextureViews fed by the platform test producers from their own threads plus a renderer drawing on the scene's own Skia context through rememberTaoGpuRenderContext; mount / unmount / swap / close-under-view / hide-show / minimize / DPI / bursts. - MonkeySupport (shared watchdog, journal, seed), PointerDrivers, NativeProbe. The journal is echoed to stderr so a native abort still leaves the sequence; -Dnucleus.tao.headful.monkeyScript replays one; the suite filter accepts a|b. What the monkeys found, all fixed: - NativeView disposed the platform view before detaching it (SIGSEGV in nativeDetach on a freed GtkWidget); nativeViewHost() returned a fresh object per call, so every recomposition of the window root detached and re-attached every embed; a late setFrame after detach touched the widget. - Linux: a right click forwarded to an embed lost its release to the widget's own context-menu grab, Compose held the button forever and every later Compose click was dead. The host now records buttons forwarded to an embed, reads GDK's live button mask on the next motion and releases the phantoms, and releases them before any new press. - Linux: printable keys never reached a focused GTK embed (Tao's toplevel IME ate them and stopped propagation), and arrows moved GTK focus into the embed through GtkWindow's move-focus binding. Tao now lets GTK propagate keys when a foreign widget owns the focus, and stops the event once Compose has consumed it. - Linux: GTK gave the map-time default focus to the embed. A focus sink now takes it, a Compose-kept press reclaims the keyboard, a press forwarded to the embed clears the Compose focus, and input boxes only grab focus when it is not already Compose's. - Linux: the embed trailed its slot by a frame or more through a resize (queue_resize waits for the frame clock); nativeSetFrame now relayouts the overlay synchronously. - Linux: a rememberTaoGpuRenderContext consumer crashed in Skia after a Wayland hide/show — the old TaoGlTextureHost bound the new EGL context for a closed DirectContext. The host is pinned to its own attachment. - All platforms: a Dialog in a native popup layer closes its layer only when the disappearance animation ends; an owner window torn down before that leaked the layer's popup window, mapped for good and eating clicks. Hosts track their layers and close the survivors on detach. NativeTaoBridge.setCursorIcon records the last requested cursor per window for the suite; NucleusPlatformView.GtkWidget documents that the app owns a g_object_ref_sink reference. --- decorated-window-tao/build.gradle.kts | 4 + .../nucleusframework/window/tao/NativeView.kt | 19 +- .../window/tao/NucleusPlatformView.kt | 8 +- .../window/tao/TextureViewMac.kt | 4 + .../window/tao/deco/ResizeFrameDecoration.kt | 4 +- .../tao/deco/TaoLinuxOverlayController.kt | 18 + .../window/tao/ffi/NativeTaoBridge.kt | 24 +- .../tao/ffi/NativeTaoLinuxWidgetBridge.kt | 53 + .../tao/ffi/NativeTaoMacOsNativeViewBridge.kt | 33 + .../ffi/NativeTaoWindowsNativeViewBridge.kt | 28 + .../window/tao/popup/TaoPopupHost.kt | 10 + .../window/tao/popup/TaoPopupHostLinux.kt | 10 + .../window/tao/popup/TaoPopupHostWindows.kt | 10 + .../window/tao/popup/TaoPopupSceneLayer.kt | 1 + .../tao/popup/TaoPopupSceneLayerLinux.kt | 3 +- .../tao/popup/TaoPopupSceneLayerWindows.kt | 1 + .../window/tao/scene/TaoComposeSceneHost.kt | 34 +- .../tao/scene/TaoComposeSceneHostLinux.kt | 163 ++- .../tao/scene/TaoComposeSceneHostWindows.kt | 32 +- .../native/linux/nucleus_tao_linux_widget.c | 280 ++++- .../src/main/native/macos/native_view.m | 98 ++ .../tao/src/platform_impl/linux/event_loop.rs | 35 +- .../windows/nucleus_tao_windows_native_view.c | 69 ++ .../window/tao/headful/MonkeySupport.kt | 223 ++++ .../window/tao/headful/NativeProbe.kt | 203 +++ .../headful/NativeViewMonkeyHeadfulCases.kt | 1100 +++++++++++++++++ .../window/tao/headful/PointerDrivers.kt | 194 +++ .../SatelliteWorkspaceMonkeyHeadfulCases.kt | 117 +- .../tao/headful/TaoHeadfulTestSuiteMain.kt | 20 +- .../headful/TextureViewMonkeyHeadfulCases.kt | 698 +++++++++++ 30 files changed, 3345 insertions(+), 151 deletions(-) create mode 100644 decorated-window-tao/src/test/kotlin/dev/nucleusframework/window/tao/headful/MonkeySupport.kt create mode 100644 decorated-window-tao/src/test/kotlin/dev/nucleusframework/window/tao/headful/NativeProbe.kt create mode 100644 decorated-window-tao/src/test/kotlin/dev/nucleusframework/window/tao/headful/NativeViewMonkeyHeadfulCases.kt create mode 100644 decorated-window-tao/src/test/kotlin/dev/nucleusframework/window/tao/headful/PointerDrivers.kt create mode 100644 decorated-window-tao/src/test/kotlin/dev/nucleusframework/window/tao/headful/TextureViewMonkeyHeadfulCases.kt diff --git a/decorated-window-tao/build.gradle.kts b/decorated-window-tao/build.gradle.kts index 05813c399..4fe01e532 100644 --- a/decorated-window-tao/build.gradle.kts +++ b/decorated-window-tao/build.gradle.kts @@ -177,6 +177,10 @@ val taoHeadfulTest by tasks.registering(JavaExec::class) { System.getProperty("nucleus.tao.headful.monkeySeed")?.let { systemProperty("nucleus.tao.headful.monkeySeed", it) } + // Replays a journal instead of a random walk (comma-separated action names). + System.getProperty("nucleus.tao.headful.monkeyScript")?.let { + systemProperty("nucleus.tao.headful.monkeyScript", it) + } System.getProperties().stringPropertyNames().filter { it.startsWith("nucleus.dialog.appearance.") }.forEach { systemProperty(it, System.getProperty(it)) } diff --git a/decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/NativeView.kt b/decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/NativeView.kt index edce3bc57..3b342a0e1 100644 --- a/decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/NativeView.kt +++ b/decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/NativeView.kt @@ -69,9 +69,10 @@ public fun NativeView( val view = remember { factory() } val latestUpdate by rememberUpdatedState(update) - DisposableEffect(view) { - onDispose { view.dispose() } - } + // `view.dispose()` is owned by [EmbeddedNativeView], sequenced *after* the + // host detach: `dispose()` promises the handle is never touched again, and + // a separate effect here ran first on unmount — the detach then walked a + // widget the app had already destroyed (SIGSEGV in `nativeDetach`).

Mon, 7 Sep 2026 00:19:51 +0300 Subject: [PATCH 103/233] fix(tao): keep a Linux embed on its slot through a Wayland resize, and stop committing GTK's surface ourselves MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The embed peeled off the Compose hole by a frame on every configure: an embedded native view's sub-surface position is parent state that only takes effect on GTK's toplevel commit, one GTK paint after Compose (which tao renders after draining the draw signal) laid the new hole out and swapped its own desync sub-surface. Through a resize burst with an embed attached, the content sub-surface now runs in set_sync mode, so the Compose buffer is applied atomically with the GTK commit that carries the embed's new position; a toplevel draw is queued after each swap so that commit always comes, including after the pointer stops. The burst's end switches back to desync, which applies any cached state at once. nativeSetContentOffset no longer issues an empty commit on GTK's toplevel surface: GDK attaches its SHM buffer in end_paint and commits in after_paint, and a commit of ours in between makes the compositor release a buffer GDK still counts as staged — buffer_release_callback fails its check and cairo aborts the process (reproduced by the texture monkey after a dozen minimize/restore cycles). The caller queues a GTK toplevel draw instead and GTK's own commit applies the offset. --- .../window/tao/ffi/NativeTaoEglBridge.kt | 14 ++++- .../tao/ffi/NativeTaoLinuxWidgetBridge.kt | 4 ++ .../tao/scene/TaoComposeSceneHostLinux.kt | 48 +++++++++++++++-- .../src/main/native/linux/nucleus_tao_egl.c | 53 +++++++++++++++---- .../native/linux/nucleus_tao_linux_widget.c | 17 ++++++ 5 files changed, 119 insertions(+), 17 deletions(-) diff --git a/decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/ffi/NativeTaoEglBridge.kt b/decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/ffi/NativeTaoEglBridge.kt index 3e2806d7d..0dbd095b7 100644 --- a/decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/ffi/NativeTaoEglBridge.kt +++ b/decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/ffi/NativeTaoEglBridge.kt @@ -119,7 +119,7 @@ internal object NativeTaoEglBridge { handle: Long, xLogical: Int, yLogical: Int, - ) + ): Boolean /** * Wayland only: declares which part of the content surface is fully opaque, @@ -209,4 +209,16 @@ internal object NativeTaoEglBridge { */ @JvmStatic external fun nativeGetProcAddrFunctionPointer(): Long + + /** + * Wayland only: puts the content sub-surface in `set_sync` (buffers apply + * with GTK's toplevel commit, atomically with the positions of embedded + * native views) or back in `set_desync` (buffers apply on their own). + * No-op on X11. + */ + @JvmStatic + external fun nativeSetSubsurfaceSync( + handle: Long, + sync: Boolean, + ) } diff --git a/decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/ffi/NativeTaoLinuxWidgetBridge.kt b/decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/ffi/NativeTaoLinuxWidgetBridge.kt index 9a1e3e17c..65c4fa155 100644 --- a/decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/ffi/NativeTaoLinuxWidgetBridge.kt +++ b/decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/ffi/NativeTaoLinuxWidgetBridge.kt @@ -206,6 +206,10 @@ internal object NativeTaoLinuxWidgetBridge { @JvmStatic external fun nativeQueryPointerButtons(gtkWindowPtr: Long): Int + /** `gtk_widget_queue_draw` on the toplevel: GTK paints and commits it on its next frame. */ + @JvmStatic + external fun nativeQueueToplevelDraw(gtkWindowPtr: Long) + // ── Diagnostics for the headful suite ───────────────────────────── /** diff --git a/decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/scene/TaoComposeSceneHostLinux.kt b/decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/scene/TaoComposeSceneHostLinux.kt index 49348b118..58040ccca 100644 --- a/decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/scene/TaoComposeSceneHostLinux.kt +++ b/decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/scene/TaoComposeSceneHostLinux.kt @@ -426,6 +426,15 @@ internal class TaoComposeSceneHostLinux( */ private var lastResizeEventNs: Long = 0L private var resizeBurstActive: Boolean = false + + /** + * Whether the content sub-surface is in `set_sync` mode — entered with the + * resize burst while an embed is attached, left when the burst ends.

Date: Mon, 7 Sep 2026 02:01:47 +0300 Subject: [PATCH 104/233] fix(tao): make the Windows embed give the pointer and the keyboard back MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The NativeView and TextureView monkeys had only ever run on Linux. On Windows they found five ways an embedded child HWND takes something from Compose and does not return it. - A press forwarded to a child is replayed to the *owner* HWND a moment later — forwarding moves Win32 focus and the queue hands the message to the window that owns the pixels. Dispatched twice, Compose ended up holding a press with no release and every later click was dead. The host now recognises the replay of the overlay event it just handled and drops it, matched on button, position and recency so a genuine second click still gets through. - The child captures the mouse on that press and keeps every later message: neither the scene nor its blending overlay would see the pointer again. The capture is handed straight back, and a release the child swallowed anyway is healed from Win32's own button state. - Keys kept going to an embed clicked into earlier while Compose showed a focused text field. A press Compose keeps now takes Win32 focus back, as the macOS host does with makeFirstResponder, and a press handed to the embed clears the Compose focus. - A child's handler may run a modal loop — an EDIT opens its context menu from WM_RBUTTONUP and does not return until it is dismissed. Everything but the press is posted rather than sent, so that loop never nests inside the Compose pointer dispatch, and the Tao loop drains the main dispatcher on a wake: Windows derives MainEventsCleared from a WM_PAINT a modal loop never generates, so the app's coroutines used to stop for as long as the menu was up. - The overlay input replay repeated whatever it saw last regardless of what the caller was forwarding; it now only replays the matching event. The suite: the robot driver types through the OS, the synthetic one dispatches into the window, and on Win32 keys go to the focused HWND — so only the robot can check that a letter reaches a focused embed. --- .../ffi/NativeTaoWindowsNativeViewBridge.kt | 25 ++ .../tao/scene/TaoComposeSceneHostWindows.kt | 229 +++++++++++++++++- .../src/main/native/src/event_loop.rs | 18 +- .../windows/nucleus_tao_windows_native_view.c | 108 ++++++++- .../windows/nucleus_tao_windows_overlay.c | 13 +- .../nucleus_tao_windows_overlay_internal.h | 8 +- .../headful/NativeViewMonkeyHeadfulCases.kt | 1 + .../window/tao/headful/PointerDrivers.kt | 9 + 8 files changed, 386 insertions(+), 25 deletions(-) diff --git a/decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/ffi/NativeTaoWindowsNativeViewBridge.kt b/decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/ffi/NativeTaoWindowsNativeViewBridge.kt index 0d5943edc..bf7c03df5 100644 --- a/decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/ffi/NativeTaoWindowsNativeViewBridge.kt +++ b/decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/ffi/NativeTaoWindowsNativeViewBridge.kt @@ -89,6 +89,31 @@ internal object NativeTaoWindowsNativeViewBridge { dy: Float, ) + /** + * Hands Win32 keyboard focus back to [parentHwnd] when a descendant (an + * embedded child) holds it, and returns whether it did.

Date: Mon, 7 Sep 2026 08:52:02 +0300 Subject: [PATCH 106/233] fix(tao): keep a Windows window painting and its focus honest around an embed MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The robot monkey went dead at a checkpoint after clicking the embed, and the synthetic one ended with a focused Compose field beside a focused embed. Four separate faults, each visible to a user with a NativeView. - The scene placed a click where the *last move it saw* left the pointer. Tao reports a button without a position and drops a WM_MOUSEMOVE whose coordinate equals the last one it saw, while every move over an embed goes to the blending overlay, which Tao knows nothing about. A pointer that left the embed and came back to a point Tao had seen before got no move at all, so the click landed on the embed the user had just left — and every click after it was dead. When the position came from the overlay, the host now asks Win32 where the pointer is and walks the scene there before dispatching. - A native modal loop on the loop thread — an embedded EDIT's context menu — stops Tao producing MainEventsCleared, which is where the Windows redraws asked for during a batch were served. The window froze for as long as the menu was up: no frames, no recomposition, and the work queued behind a frame never ran. The wake that already drains the dispatcher inside such a loop now serves those redraws too. - A press handed to an embed cleared the Compose focus through the frame queue, so if that very press was the one opening the embed's menu, the clear waited for a frame that could not come and the field kept its caret next to the embed's. It goes through the main dispatcher instead, which runs inside the modal loop. - Handing an event to a child HWND runs its handler on this thread, and anything it pumps swallows the redraw the window had pending; the coalescing latch then suppressed every later request. Reset after a forwarded dispatch, like the other nested-pump callers. Also: closing a native popup layer is idempotent now. The detach sweep added with the layer leak fix closes surviving layers itself, and Compose then disposes the same layer as the composition unwinds — the second pass released the native panel twice and took the process down. The caret assertion asks the field for its caret instead of inferring it from where the next letter lands, and accepts a move from a caret the value left past the end of the text. --- .../ffi/NativeTaoWindowsNativeViewBridge.kt | 9 ++ .../window/tao/popup/TaoPopupSceneLayer.kt | 5 + .../tao/popup/TaoPopupSceneLayerWindows.kt | 5 + .../tao/scene/TaoComposeSceneHostWindows.kt | 98 +++++++++++++++++-- .../src/main/native/src/event_loop.rs | 48 +++++---- .../windows/nucleus_tao_windows_native_view.c | 21 ++++ .../headful/NativeViewMonkeyHeadfulCases.kt | 38 ++++--- 7 files changed, 188 insertions(+), 36 deletions(-) diff --git a/decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/ffi/NativeTaoWindowsNativeViewBridge.kt b/decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/ffi/NativeTaoWindowsNativeViewBridge.kt index bf7c03df5..ec5184900 100644 --- a/decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/ffi/NativeTaoWindowsNativeViewBridge.kt +++ b/decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/ffi/NativeTaoWindowsNativeViewBridge.kt @@ -114,6 +114,15 @@ internal object NativeTaoWindowsNativeViewBridge { @JvmStatic external fun nativeReleaseChildCapture(parentHwnd: Long): Boolean + /** + * The pointer's position in [parentHwnd]'s client pixels, packed as + * `(x shl 32) or (y and 0xffffffff)`, or [Long.MIN_VALUE] when it cannot + * be read.

Mutter's focus-stealing prevention drops `_NET_ACTIVE_WINDOW` requests carrying `GDK_CURRENT_TIME` (0) and keeps a deiconified window Iconic with `_NET_WM_STATE_DEMANDS_ATTENTION`, so restore/focus silently no-op and `EVENT_MINIMIZED(false)` never fires on GNOME X11/XWayland (openbox honors the 0 timestamp, which is why CI never saw it). No-op on Wayland. | | 0006 | `0006-linux-cursor-ignore-events-region.patch` | 6 | Linux | `CursorIgnoreEvents`: install a genuinely *empty* input region instead of upstream's 1x1 rectangle at the origin (which leaves the top-left pixel clickable), and clear it through the same `GdkWindow` with a NULL region. Upstream cleared it on the `GtkWidget`, which never undid a shape installed on the `GdkWindow`, so click-through could not be switched back off. | | 0007 | `0007-linux-outer-geometry-placeholder.patch` | 7 | Linux | Stop latching GDK's `(0, 0, 1, 1)` frame-extents placeholder into `outer_position` / `outer_size`. `gdk_window_get_frame_extents` answers with it until the window is mapped and framed, so a `configure-event` that lands in that window pins it until the *next* one — seconds away, or never, on a software-rendered X server under a lightweight WM (the CI Xvfb + openbox leg). Consumers then read a 1x1 window at the screen origin: a torn-off window 1 dp wide, a satellite anchored against a 1px-tall child, a pointer aimed at a negative screen coordinate. The size falls back to the configure event's own (the whole surface, shadow included — what the frame is under CSD, and what `configure_client_size` subtracts the insets from); the position is kept as it was, since every substitute is wrong in a worse way — `event.position()` is frame-relative under a reparenting WM, `root_origin` goes back through `frame_extents`, and `gdk_window_get_origin` names the client rather than the frame. | +| 0008 | `0008-macos-scroll-phase-and-horizontal-sign.patch` | 8 | macOS (+ field on all backends) | `WindowEvent::MouseWheel` gains `scroll_phase: ScrollPhase` — the full AppKit `phase` / `momentumPhase` of a trackpad scroll (`None` for a wheel, and on Windows / Linux), which `TouchPhase` cannot express; Nucleus routes gesture steps to Compose Pan events (#654). Also stops negating `scrollingDeltaX` in `scroll_wheel`: AppKit's sign already matches `MouseScrollDelta`'s documented convention (and winit), and the extra flip reversed horizontal trackpad scrolling once the consumer applied the AWT convention (#652). `PixelDelta` carries AppKit's logical points instead of `x backing scale`: AWT's `preciseWheelRotation` never sees the display scale (#653), and undoing the multiplication downstream with a second scale cache disagreed with the view's for a frame during display hops. | ## Bump procedure (e.g. 0.35 → 0.36) diff --git a/decorated-window-tao/src/main/native/vendor/tao/src/event.rs b/decorated-window-tao/src/main/native/vendor/tao/src/event.rs index 005858573..2b80b12ec 100644 --- a/decorated-window-tao/src/main/native/vendor/tao/src/event.rs +++ b/decorated-window-tao/src/main/native/vendor/tao/src/event.rs @@ -444,6 +444,9 @@ pub enum WindowEvent<'a> { device_id: DeviceId, delta: MouseScrollDelta, phase: TouchPhase, + /// PATCH(nucleus): fine-grained trackpad gesture / momentum phase; + /// [`ScrollPhase::None`] for a mouse wheel.

That layout is now expressible, and every pane of it is a satellite, so it can also be torn into a window of its own. - `SatellitePlacement.Docked` carries the panel's own `extent` and `weight`; both ride in `SatelliteLayoutSnapshot` and are driven by `setDockedExtent` / `setDockedWeight`. - `DockLayout(sideOrder, layeredSides, splitter, panel)`: sides nest outermost-first, so a side can own the corners; a side is either *split* (panels share its length by weight, thickness by `dockExtent`) or *layered* (each panel a full-length layer of its own extent, with its own splitter). - The `splitter` and `panel` slots hand the chrome to the app — `DockSplitterScope.dockSplitterHandle()` carries the gesture, so a 1 dp line with a wider overflowing grip works — and the default header no longer imposes a height or a background on a docked panel. - Sides are physical: the layout composes LTR internally and gives the caller's direction back to the content, the panels and the slots, so a right-to-left app gets `DockSide.Left` on the left of the screen. - Every panel and the content are `movableContentOf`: no change of the layout — extent, weight, order, side, restore, side order, direction, a resize — rebuilds a subtree, so a docked pane keeps its scroll position and its `remember`s. Extents are fitted proportionally when the window is too small. - Drop feedback is drawn at the rectangle the release produces and hit-tested against that same rectangle: the side's own band, inset behind existing layers, counting the dragged panel's side as already freed, at the width `dock()` will apply. A zone is entered when the dragged satellite's edge reaches it — the palette, not the pointer — and the side a panel already occupies is neither drawn nor droppable. - `examples/reader-dock-demo`: the whole thing as a right-to-left book reader, with the reader's own dividers, hover headers and Islands style. Covered by 435 unit tests (the new classes registered in the GraalVM battery), 10 real-window cases with robot-driven splitter drags and 13 dock-layout monkeys (4 layout profiles x 3 seeds plus a 400-action run). --- CLAUDE.md | 4 +- .../api/decorated-window-tao.api | 40 +- .../nucleusframework/window/tao/DockLayout.kt | 719 ++++++++------ .../window/tao/DockSplitter.kt | 129 +++ .../window/tao/DockTransferTarget.kt | 100 ++ .../window/tao/DockZoneHints.kt | 160 ++++ .../nucleusframework/window/tao/Satellite.kt | 20 +- .../window/tao/SatelliteDragSessions.kt | 21 +- .../window/tao/SatellitePlacement.kt | 48 +- .../window/tao/SatelliteWorkspace.kt | 230 ++++- .../window/tao/workspace/HostGeometry.kt | 27 + .../window/tao/DockLandingRectTest.kt | 254 +++++ .../window/tao/SatelliteDockedGeometryTest.kt | 151 +++ .../window/tao/SatelliteWorkspaceTest.kt | 41 +- .../window/tao/TaoSceneTestBattery.kt | 69 ++ .../tao/TaoSceneTestBatteryDriftTest.kt | 4 + .../window/tao/headful/DockLayoutFixture.kt | 284 ++++++ .../tao/headful/DockLayoutHeadfulCases.kt | 887 ++++++++++++++++++ .../headful/DockLayoutMonkeyHeadfulCases.kt | 582 ++++++++++++ .../tao/headful/TaoHeadfulTestSuiteMain.kt | 2 + .../tao/headful/WorkspaceChaosSupport.kt | 23 +- examples/reader-dock-demo/build.gradle.kts | 51 + .../nucleusframework/readerdockdemo/Main.kt | 325 +++++++ .../readerdockdemo/ReaderChrome.kt | 186 ++++ .../readerdockdemo/ReaderState.kt | 80 ++ settings.gradle.kts | 1 + 26 files changed, 4105 insertions(+), 333 deletions(-) create mode 100644 decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/DockSplitter.kt create mode 100644 decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/DockTransferTarget.kt create mode 100644 decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/DockZoneHints.kt create mode 100644 decorated-window-tao/src/test/kotlin/dev/nucleusframework/window/tao/DockLandingRectTest.kt create mode 100644 decorated-window-tao/src/test/kotlin/dev/nucleusframework/window/tao/SatelliteDockedGeometryTest.kt create mode 100644 decorated-window-tao/src/test/kotlin/dev/nucleusframework/window/tao/headful/DockLayoutFixture.kt create mode 100644 decorated-window-tao/src/test/kotlin/dev/nucleusframework/window/tao/headful/DockLayoutHeadfulCases.kt create mode 100644 decorated-window-tao/src/test/kotlin/dev/nucleusframework/window/tao/headful/DockLayoutMonkeyHeadfulCases.kt create mode 100644 examples/reader-dock-demo/build.gradle.kts create mode 100644 examples/reader-dock-demo/src/main/kotlin/dev/nucleusframework/readerdockdemo/Main.kt create mode 100644 examples/reader-dock-demo/src/main/kotlin/dev/nucleusframework/readerdockdemo/ReaderChrome.kt create mode 100644 examples/reader-dock-demo/src/main/kotlin/dev/nucleusframework/readerdockdemo/ReaderState.kt diff --git a/CLAUDE.md b/CLAUDE.md index 5da10110e..ab9b5a52b 100644 --- a/CLAUDE.md +++ b/CLAUDE.md @@ -37,13 +37,13 @@ Published releases are `2.5.x` (latest tag `v2.5.0`).

Extents are fitted proportionally when the window is too small (`fit`). Drop feedback lives in `DockZoneHints.kt` and **the rectangles it draws are the target**: it publishes them to `HostGeometry.zoneBoundsInWindowPx`, and `dockTargetAt(draggedScreenRectPx, pointerScreenPx)` → `dockSideEntered` resolves a drop against those, not against the window's edges — on a layered side the strip is inset behind the existing layers, and the window's own edge behind them is nothing. A zone is entered when the dragged **satellite's** edge (its window, or the tear-out ghost) is within one zone thickness of the zone's outer edge and overlaps it across the other axis — edge alignment, not overlap, or a full-height panel could never be torn out; the pointer inside a zone is a second trigger and the tie-break, else the smallest gap wins. The rects come from `DockLayoutState.landingRectPx`: the side's measured band, inside existing layers, counting the dragged panel's own side as already freed; `hintedSides` drops the side the panel already occupies in that window, so it is neither drawn nor droppable. The Wayland DnD path (`DockTransferTarget`) hit-tests the same published rects. `dock()` and the preview share one width (`dockSeedExtent`), so what lights up is what the release produces.

snapshots restored on top of + * whatever the previous steps left. Each profile is a layout an app would + * actually declare — the reader layout of a right-to-left book app among them — + * and each is run under several seeds, because the interleavings are the point. + * + * What a run asserts, after every action and at checkpoints: + * + * - **geometry**: no two visible panels overlap, none overlaps the content, + * and every one is inside the layout — whatever the extents, weights, order + * and direction happen to be; + * - **identity**: a panel body is built once per *hosting change* (docked to + * floating, closed to open, hidden to shown) and never by a change of the + * layout alone — a splitter, a reorder, a side change, a restore, a new + * side order or direction must move a subtree, not rebuild it. The content + * is never rebuilt at all; + * - **composition**: no panel composes in two hosts once a step has settled; + * - **liveness**: `Dispatchers.Main` keeps answering ([MainLoopWatchdog]), + * no action wedges, and native windows do not accumulate; + * - **convergence**: the closing phase docks everything back into one + * layered configuration and it has to lay out cleanly. + * + * Every failure carries the profile, the seed and the last actions; + * `-Dnucleus.tao.headful.monkeySeed=` replays the action sequence and + * `-Dnucleus.tao.headful.monkeyScript=A,B,C` replays a journal

Closed panels keep their rank. - `DockTarget.order`: a side with panels publishes one slot per rank (`DockDropZone.slots`, cut at the neighbours' centres, the dragged panel excluded) and the pointer over the stack picks the rank — its own being no target. Drawn as an insertion bar between the two panels; a new innermost layer and an empty side keep the rectangle they promised. A pointer over a stack beats a strip running across its corner. The Wayland transfer path resolves the same slots. Covered by new unit classes (ranks, slots, bars, hit test, a drag session that reorders), three real-window cases on X11 (return to rank after undock, robot drag of a layer to the first rank, split side reorder with a closed panel in the middle) and one on native Wayland. --- CLAUDE.md | 2 +- .../api/decorated-window-tao.api | 9 +- .../nucleusframework/window/tao/DockLayout.kt | 104 +++++- .../window/tao/DockTransferTarget.kt | 23 +- .../window/tao/DockZoneHints.kt | 153 +++++--- .../window/tao/SatelliteDragSessions.kt | 16 +- .../window/tao/SatellitePlacement.kt | 11 +- .../window/tao/SatelliteWorkspace.kt | 177 +++++++-- .../window/tao/workspace/HostGeometry.kt | 42 ++- .../window/tao/DockLandingRectTest.kt | 171 ++++++++- .../window/tao/SatelliteDockRankTest.kt | 218 +++++++++++ .../window/tao/SatelliteWorkspaceTest.kt | 17 - .../window/tao/TaoSceneTestBattery.kt | 50 ++- .../tao/TaoSceneTestBatteryDriftTest.kt | 2 + .../window/tao/headful/DockLayoutFixture.kt | 25 ++ .../tao/headful/DockLayoutHeadfulCases.kt | 341 +++++++++++++++++- .../headful/WaylandWorkspaceHeadfulCases.kt | 92 ++++- 17 files changed, 1319 insertions(+), 134 deletions(-) create mode 100644 decorated-window-tao/src/test/kotlin/dev/nucleusframework/window/tao/SatelliteDockRankTest.kt diff --git a/CLAUDE.md b/CLAUDE.md index ab9b5a52b..0dc001716 100644 --- a/CLAUDE.md +++ b/CLAUDE.md @@ -37,7 +37,7 @@ Published releases are `2.5.x` (latest tag `v2.5.0`).

Extents are fitted proportionally when the window is too small (`fit`). Drop feedback lives in `DockZoneHints.kt` and **the rectangles it draws are the target**: it publishes them to `HostGeometry.zoneBoundsInWindowPx`, and `dockTargetAt(draggedScreenRectPx, pointerScreenPx)` → `dockSideEntered` resolves a drop against those, not against the window's edges — on a layered side the strip is inset behind the existing layers, and the window's own edge behind them is nothing. A zone is entered when the dragged **satellite's** edge (its window, or the tear-out ghost) is within one zone thickness of the zone's outer edge and overlaps it across the other axis — edge alignment, not overlap, or a full-height panel could never be torn out; the pointer inside a zone is a second trigger and the tie-break, else the smallest gap wins. The rects come from `DockLayoutState.landingRectPx`: the side's measured band, inside existing layers, counting the dragged panel's own side as already freed; `hintedSides` drops the side the panel already occupies in that window, so it is neither drawn nor droppable.

Headful coverage: `DockLayoutHeadfulCases` (robot splitter drags) + `DockLayoutMonkeyHeadfulCases` (profiles × seeds, `-Dnucleus.tao.headful.filter="dock layout"`). +- `decorated-window-tao` internals: `window/tao/workspace/` is the shared, `internal` core behind the multi-window archetypes — `WindowGroup` (membership, focus recency, pinning), `RelocatedContentHost` + `RelocatingSaveableStateRegistry` (`rememberSaveable` state that follows content between windows), `HostGeometry` (drop targets in physical screen px), `CrossWindowDrag` (one live drag, screen-space drag handle), `DragGhostWindow`, `ScreenPlacement` (`supportsScreenPlacement`: the native-Wayland gate — GDK reports every toplevel at `(0, 0)` and ignores moves, so anything that treats `outerBoundsPx()`'s origin as a screen coordinate must check it; the size half stays valid there), `TransferDrag` (the native-Wayland path of every cross-window gesture: the grip starts a platform **drag-and-drop** session carrying an in-process token (`TaoPrivateTransfer`, `SAME_APP` only), the window under the pointer resolves the drop in its *own* coordinates and records it on the session, and the source acts on that record when the session ends — inverted roles versus `ScreenDrag`, because the source is told nothing about where the pointer is; the drag icon is a reduced snapshot of the dragged palette or panel, taken through `TaoWindow.contentSnapshot`). `SatelliteWorkspace` (docking) and `TabWorkspace` (Chrome-like tabs) are both built on it — put new cross-window gestures there rather than duplicating the geometry or the drag bookkeeping. `DockLayout` (`window/tao/DockLayout.kt` + `DockSplitter.kt` + `DockTransferTarget.kt`) is the dock: sides nest in `sideOrder` (outermost first, default `DefaultDockSideOrder` = top, bottom, left, right — **not** `DockSide.entries`, whose declaration order is left, right, top, bottom), a side is either *split* (panels share its length by `Docked.weight` and its thickness by `dockExtent(side)`) or *layered* (`layeredSides`: each panel a full-length layer of its own `Docked.extent`, the way a nested split-pane tree looks), `splitter` / `panel` slots carry the app's own chrome (`DockSplitterScope.dockSplitterHandle()` is the gesture; an overflowing `requiredWidth` grip on a 1 dp line works), sides are physical and the layout forces LTR internally then restores the caller's direction for content/panels/slots, and every panel and the content are `movableContentOf` so no layout change (extent, weight, order, side, restore, side order, direction) rebuilds a subtree — the layout's inputs live in `DockLayoutState` as snapshot state because the bands are separate composables that strong skipping would otherwise skip. Extents are fitted proportionally when the window is too small (`fit`). Drop feedback lives in `DockZoneHints.kt` and **the rectangles it draws are the target**: it publishes them to `HostGeometry.zoneBoundsInWindowPx`, and `dockTargetAt(draggedScreenRectPx, pointerScreenPx)` → `dockSideEntered` resolves a drop against those, not against the window's edges — on a layered side the strip is inset behind the existing layers, and the window's own edge behind them is nothing. A zone is entered when the dragged **satellite's** edge (its window, or the tear-out ghost) is within one zone thickness of the zone's outer edge and overlaps it across the other axis — edge alignment, not overlap, or a full-height panel could never be torn out; the pointer inside a zone is a second trigger and the tie-break, else the smallest gap wins. The rects come from `DockLayoutState.landingRectPx`: the side's measured band, inside existing layers, counting the dragged panel's own side as already freed; `hintedSides` drops the side the panel is alone on in that window, so it is neither drawn nor droppable. **Ranks**: `Docked.order` is kept contiguous from 0 per (host, side) by `dock()` / `undock()` (`dock(order)` inserts at that index, `null` = the rank the entry last held on that side, remembered in `SatelliteEntry.dockMemory`, else the end), and a side with panels publishes `DockDropZone.slots` — one rect per rank, cut at the neighbours' centres, the dragged panel excluded — so `DockTarget.order` is the rank under the pointer (`dockSlotAt`), drawn as an insertion bar (`insertionBarPx`), the own rank (`ownTarget`) being no target; a pointer over a stack beats a strip across its corner. `dropAt` converts a shown-rank into the full rank (closed panels keep theirs). The Wayland DnD path (`DockTransferTarget`) hit-tests the same published zones. A hand-driven `beginDrag` session must wait for the zones to be published before its first sample, or it resolves against the bare edges. `dock()` and the preview share one width (`dockSeedExtent`), so what lights up is what the release produces.

A declared docked placement must name an allowed side. - `preferredDockSide` starts on an allowed side, so the header's Dock button always has somewhere to go. - `reader-dock-demo` declares its panes for the left, right and bottom only: the top strip never lights up. Covered by `SatelliteDockSidesTest` (5 cases, in the GraalVM battery) and a real-window case: the top is neither hinted nor published, a release there leaves the palette floating, a direct dock is refused, and the left side still takes it. --- CLAUDE.md | 2 +- .../api/decorated-window-tao.api | 7 +- .../window/tao/DockTransferTarget.kt | 5 +- .../window/tao/DockZoneHints.kt | 5 +- .../nucleusframework/window/tao/Satellite.kt | 10 +- .../window/tao/SatelliteDragSessions.kt | 6 +- .../window/tao/SatelliteWorkspace.kt | 40 ++++- .../window/tao/SatelliteDockSidesTest.kt | 161 ++++++++++++++++++ .../window/tao/TaoSceneTestBattery.kt | 21 +++ .../tao/TaoSceneTestBatteryDriftTest.kt | 1 + .../window/tao/headful/DockLayoutFixture.kt | 2 + .../tao/headful/DockLayoutHeadfulCases.kt | 139 ++++++++++++++- .../nucleusframework/readerdockdemo/Main.kt | 1 + .../readerdockdemo/ReaderState.kt | 7 + .../api/nucleus-application.api | 8 +- .../nucleusframework/application/Satellite.kt | 7 + .../internal/TaoSatelliteWorkspaceAdapter.kt | 3 + 17 files changed, 402 insertions(+), 23 deletions(-) create mode 100644 decorated-window-tao/src/test/kotlin/dev/nucleusframework/window/tao/SatelliteDockSidesTest.kt diff --git a/CLAUDE.md b/CLAUDE.md index 0dc001716..a2e977671 100644 --- a/CLAUDE.md +++ b/CLAUDE.md @@ -37,7 +37,7 @@ Published releases are `2.5.x` (latest tag `v2.5.0`).

Extents are fitted proportionally when the window is too small (`fit`). Drop feedback lives in `DockZoneHints.kt` and **the rectangles it draws are the target**: it publishes them to `HostGeometry.zoneBoundsInWindowPx`, and `dockTargetAt(draggedScreenRectPx, pointerScreenPx)` → `dockSideEntered` resolves a drop against those, not against the window's edges — on a layered side the strip is inset behind the existing layers, and the window's own edge behind them is nothing. A zone is entered when the dragged **satellite's** edge (its window, or the tear-out ghost) is within one zone thickness of the zone's outer edge and overlaps it across the other axis — edge alignment, not overlap, or a full-height panel could never be torn out; the pointer inside a zone is a second trigger and the tie-break, else the smallest gap wins. The rects come from `DockLayoutState.landingRectPx`: the side's measured band, inside existing layers, counting the dragged panel's own side as already freed; `hintedSides` drops the side the panel is alone on in that window, so it is neither drawn nor droppable. **Ranks**: `Docked.order` is kept contiguous from 0 per (host, side) by `dock()` / `undock()` (`dock(order)` inserts at that index, `null` = the rank the entry last held on that side, remembered in `SatelliteEntry.dockMemory`, else the end), and a side with panels publishes `DockDropZone.slots` — one rect per rank, cut at the neighbours' centres, the dragged panel excluded — so `DockTarget.order` is the rank under the pointer (`dockSlotAt`), drawn as an insertion bar (`insertionBarPx`), the own rank (`ownTarget`) being no target; a pointer over a stack beats a strip across its corner. `dropAt` converts a shown-rank into the full rank (closed panels keep theirs). The Wayland DnD path (`DockTransferTarget`) hit-tests the same published zones. A hand-driven `beginDrag` session must wait for the zones to be published before its first sample, or it resolves against the bare edges. `dock()` and the preview share one width (`dockSeedExtent`), so what lights up is what the release produces.

Drop feedback lives in `DockZoneHints.kt` and **the rectangles it draws are the target**: it publishes them to `HostGeometry.zoneBoundsInWindowPx`, and `dockTargetAt(draggedScreenRectPx, pointerScreenPx)` → `dockSideEntered` resolves a drop against those, not against the window's edges — on a layered side the strip is inset behind the existing layers, and the window's own edge behind them is nothing. A zone is entered when the dragged **satellite's** edge (its window, or the tear-out ghost) is within one zone thickness of the zone's outer edge and overlaps it across the other axis — edge alignment, not overlap, or a full-height panel could never be torn out; the pointer inside a zone is a second trigger and the tie-break, else the smallest gap wins. The rects come from `DockLayoutState.landingRectPx`: the side's measured band, inside existing layers, counting the dragged panel's own side as already freed; `hintedSides` drops the side the panel is alone on in that window, so it is neither drawn nor droppable. **`dockSides`**: `Satellite(dockSides = …)` (default all four, empty = floating-only) is fixed at declaration and enforced everywhere — `dock()` and `restore()` refuse another side, `hintedSides` and `DockZoneHints` neither draw nor publish it, the drag sessions resolve through `dockTargetFor(entry, …)` and the Wayland target filters on `drag.entry.dockSides`, and the default header hides its Dock action for a floating-only palette. **Ranks**: `Docked.order` is kept contiguous from 0 per (host, side) by `dock()` / `undock()` (`dock(order)` inserts at that index, `null` = the rank the entry last held on that side, remembered in `SatelliteEntry.dockMemory`, else the end), and a side with panels publishes `DockDropZone.slots` — one rect per rank, cut at the neighbours' centres, the dragged panel excluded — so `DockTarget.order` is the rank under the pointer (`dockSlotAt`), drawn as an insertion bar (`insertionBarPx`), the own rank (`ownTarget`) being no target; a pointer over a stack beats a strip across its corner. `dropAt` converts a shown-rank into the full rank (closed panels keep theirs). The Wayland DnD path (`DockTransferTarget`) hit-tests the same published zones. A hand-driven `beginDrag` session must wait for the zones to be published before its first sample, or it resolves against the bare edges. `dock()` and the preview share one width (`dockSeedExtent`), so what lights up is what the release produces.

Extents are fitted proportionally when the window is too small (`fit`). Drop feedback lives in `DockZoneHints.kt` and **the rectangles it draws are the target**: it publishes them to `HostGeometry.zoneBoundsInWindowPx`, and `dockTargetAt(draggedScreenRectPx, pointerScreenPx)` → `dockSideEntered` resolves a drop against those, not against the window's edges — on a layered side the strip is inset behind the existing layers, and the window's own edge behind them is nothing. A zone is entered when the dragged **satellite's** edge (its window, or the tear-out ghost) is within one zone thickness of the zone's outer edge and overlaps it across the other axis — edge alignment, not overlap, or a full-height panel could never be torn out; the pointer inside a zone is a second trigger and the tie-break, else the smallest gap wins. The rects come from `DockLayoutState.landingRectPx`: the side's measured band, inside existing layers, counting the dragged panel's own side as already freed; `hintedSides` drops the side the panel is alone on in that window, so it is neither drawn nor droppable. **`dockSides`**: `Satellite(dockSides = …)` (default all four, empty = floating-only) is fixed at declaration and enforced everywhere — `dock()` and `restore()` refuse another side, `hintedSides` and `DockZoneHints` neither draw nor publish it, the drag sessions resolve through `dockTargetFor(entry, …)` and the Wayland target filters on `drag.entry.dockSides`, and the default header hides its Dock action for a floating-only palette. **Ranks**: `Docked.order` is kept contiguous from 0 per (host, side) by `dock()` / `undock()` (`dock(order)` inserts at that index, `null` = the rank the entry last held on that side, remembered in `SatelliteEntry.dockMemory`, else the end), and a side with panels publishes `DockDropZone.slots` — one rect per rank, cut at the neighbours' centres, the dragged panel excluded — so `DockTarget.order` is the rank under the pointer (`dockSlotAt`), drawn as an insertion bar (`insertionBarPx`), the own rank (`ownTarget`) being no target; a pointer over a stack beats a strip across its corner. `dropAt` converts a shown-rank into the full rank (closed panels keep theirs). The Wayland DnD path (`DockTransferTarget`) hit-tests the same published zones. A hand-driven `beginDrag` session must wait for the zones to be published before its first sample, or it resolves against the bare edges. `dock()` and the preview share one width (`dockSeedExtent`), so what lights up is what the release produces.

The rects come from `DockLayoutState.landingRectPx`: the side's measured band, inside existing layers, counting the dragged panel's own side as already freed; `hintedSides` drops the side the panel is alone on in that window, so it is neither drawn nor droppable. **`dockSides`**: `Satellite(dockSides = …)` (default all four, empty = floating-only) is fixed at declaration and enforced everywhere — `dock()` and `restore()` refuse another side, `hintedSides` and `DockZoneHints` neither draw nor publish it, the drag sessions resolve through `dockTargetFor(entry, …)` and the Wayland target filters on `drag.entry.dockSides`, and the default header hides its Dock action for a floating-only palette. **`floatable = false`** is the opposite knob — a fixed panel: `undock()` refuses it, a `restore()` that floats it is ignored, the docked drag publishes no tear-out ghost and a release off every zone leaves it in place, the default header drops its Float action, and the declaration requires a docked `initialPlacement` (`reader-dock-demo`: the book tree and the contents are `floatable = false` + `dockSides = setOf(Right)`, still reorderable between themselves). **Ranks**: `Docked.order` is kept contiguous from 0 per (host, side) by `dock()` / `undock()` (`dock(order)` inserts at that index, `null` = the rank the entry last held on that side, remembered in `SatelliteEntry.dockMemory`, else the end), and a side with panels publishes `DockDropZone.slots` — one rect per rank, cut at the neighbours' centres, the dragged panel excluded — so `DockTarget.order` is the rank under the pointer (`dockSlotAt`), drawn as an insertion bar (`insertionBarPx`), the own rank (`ownTarget`) being no target; a pointer over a stack beats a strip across its corner. `dropAt` converts a shown-rank into the full rank (closed panels keep theirs). The Wayland DnD path (`DockTransferTarget`) hit-tests the same published zones. A hand-driven `beginDrag` session must wait for the zones to be published before its first sample, or it resolves against the bare edges. `dock()` and the preview share one width (`dockSeedExtent`), so what lights up is what the release produces.

Requires a docked `initialPlacement`. - The ranks in front of a pinned panel stay in the published slots as empty rects, so a slot's index is still the rank it stands for and a drop aimed at a pinned panel lands right behind it, where the bar is drawn. - `Modifier.satelliteDragHandle` is inert on a satellite a drag could not move anywhere — pinned, fixed to the side it is on, and alone in the workspace — instead of leaving a gesture that can only end where it began. - `reader-dock-demo`: the book tree and the contents are furniture now — no tear-out, no side change, no reorder, and nothing docks in front of them. Covered by four unit cases (in the GraalVM battery) plus the layered-side geometry, and the real-window case now checks that the neighbour docked at rank 0 lands behind the pinned panel and that the pinned one is offered nothing at all. --- CLAUDE.md | 2 +- .../api/decorated-window-tao.api | 7 +- .../nucleusframework/window/tao/DockLayout.kt | 21 +++++- .../window/tao/DockTransferTarget.kt | 6 +- .../window/tao/DockZoneHints.kt | 14 ++-- .../nucleusframework/window/tao/Satellite.kt | 33 ++++++-- .../window/tao/SatelliteWorkspace.kt | 70 +++++++++++++++-- .../window/tao/workspace/HostGeometry.kt | 8 +- .../window/tao/DockLandingRectTest.kt | 34 +++++++++ .../window/tao/SatelliteFixedPanelTest.kt | 75 +++++++++++++++++-- .../window/tao/TaoSceneTestBattery.kt | 16 +++- .../window/tao/headful/DockLayoutFixture.kt | 2 + .../tao/headful/DockLayoutHeadfulCases.kt | 43 ++++++++++- .../nucleusframework/readerdockdemo/Main.kt | 1 + .../readerdockdemo/ReaderState.kt | 7 +- .../api/nucleus-application.api | 8 +- .../nucleusframework/application/Satellite.kt | 7 ++ .../internal/TaoSatelliteWorkspaceAdapter.kt | 2 + 18 files changed, 304 insertions(+), 52 deletions(-) diff --git a/CLAUDE.md b/CLAUDE.md index a37144809..13febe2e6 100644 --- a/CLAUDE.md +++ b/CLAUDE.md @@ -37,7 +37,7 @@ Published releases are `2.5.x` (latest tag `v2.5.0`).

Nucleus already split the title bar for that, but nothing about the split was public: the capability was internal, the reserved strip was a private constant, and a custom header had no way to adapt the way the stock one does. - `TaoWindow.canPlaceOnScreen` is the public capability (the internal `supportsScreenPlacement` is gone). Branch on it rather than on `isNativeWaylandSurface`: it is the question — can the app place this window — not the platform that answers it. - `SatelliteScope.isCompositorPlaced` gives custom chrome the same answer for the window it is composed in; the floating scope reads the satellite's own window, a docked panel reads its host. - `Satellite(floatingCaption = …)` fills the strip the title bar leaves to the compositor's move, `SatelliteCaptionStripWidth` wide, composed only where one is reserved — so an app never guesses that width nor accidentally claims the only area that can move the palette. - `SatelliteWorkspace.dragKind` (`Window` / `Transfer`) says how the drag in flight is carried, which is what tells preview code whether `dragGhost` will ever be published. - `reader-dock-demo` draws a move glyph in that strip. Covered by three unit cases in the GraalVM battery plus both halves of the contract on real windows: the X11 case asserts nothing is reserved and a drag is window-carried, the native-Wayland one asserts the strip is reserved at the published width, the panel and the palette are both told, and the drag is transfer-carried with no ghost. --- CLAUDE.md | 2 +- .../api/decorated-window-tao.api | 19 +++- .../nucleusframework/window/tao/DockLayout.kt | 4 +- .../nucleusframework/window/tao/Satellite.kt | 81 +++++++++++++--- .../window/tao/SatelliteWindow.kt | 5 +- .../window/tao/SatelliteWorkspace.kt | 42 ++++++++- .../window/tao/TabWorkspace.kt | 3 +- .../nucleusframework/window/tao/TaoWindow.kt | 22 +++++ .../window/tao/workspace/CrossWindowDrag.kt | 4 +- .../window/tao/workspace/HostGeometry.kt | 4 +- .../window/tao/workspace/ScreenPlacement.kt | 21 +---- .../window/tao/workspace/TransferDrag.kt | 2 +- .../window/tao/SatelliteDragKindTest.kt | 89 ++++++++++++++++++ .../window/tao/TaoSceneTestBattery.kt | 9 ++ .../tao/TaoSceneTestBatteryDriftTest.kt | 1 + .../window/tao/headful/DockLayoutFixture.kt | 25 +++++ .../tao/headful/DockLayoutHeadfulCases.kt | 94 +++++++++++++++++++ .../headful/WaylandWorkspaceHeadfulCases.kt | 84 +++++++++++++++++ .../nucleusframework/readerdockdemo/Main.kt | 3 + .../readerdockdemo/ReaderChrome.kt | 20 ++++ .../api/nucleus-application.api | 10 +- .../nucleusframework/application/Satellite.kt | 7 ++ .../internal/TaoSatelliteWorkspaceAdapter.kt | 2 + 23 files changed, 502 insertions(+), 51 deletions(-) create mode 100644 decorated-window-tao/src/test/kotlin/dev/nucleusframework/window/tao/SatelliteDragKindTest.kt diff --git a/CLAUDE.md b/CLAUDE.md index 13febe2e6..be71cf14a 100644 --- a/CLAUDE.md +++ b/CLAUDE.md @@ -37,7 +37,7 @@ Published releases are `2.5.x` (latest tag `v2.5.0`).

Extents are fitted proportionally when the window is too small (`fit`). Drop feedback lives in `DockZoneHints.kt` and **the rectangles it draws are the target**: it publishes them to `HostGeometry.zoneBoundsInWindowPx`, and `dockTargetAt(draggedScreenRectPx, pointerScreenPx)` → `dockSideEntered` resolves a drop against those, not against the window's edges — on a layered side the strip is inset behind the existing layers, and the window's own edge behind them is nothing. A zone is entered when the dragged **satellite's** edge (its window, or the tear-out ghost) is within one zone thickness of the zone's outer edge and overlaps it across the other axis — edge alignment, not overlap, or a full-height panel could never be torn out; the pointer inside a zone is a second trigger and the tie-break, else the smallest gap wins. The rects come from `DockLayoutState.landingRectPx`: the side's measured band, inside existing layers, counting the dragged panel's own side as already freed; `hintedSides` drops the side the panel is alone on in that window, so it is neither drawn nor droppable. **`dockSides`**: `Satellite(dockSides = …)` (default all four, empty = floating-only) is fixed at declaration and enforced everywhere — `dock()` and `restore()` refuse another side, `hintedSides` and `DockZoneHints` neither draw nor publish it, the drag sessions resolve through `dockTargetFor(entry, …)` and the Wayland target filters on `drag.entry.dockSides`, and the default header hides its Dock action for a floating-only palette. **`floatable = false`** is the opposite knob — a fixed panel: `undock()` refuses it, a `restore()` that floats it is ignored, the docked drag publishes no tear-out ghost and a release off every zone leaves it in place, the default header drops its Float action, and the declaration requires a docked `initialPlacement`. **`reorderable = false`** pins the rank: `dock(order)` is ignored for it (it takes the declared rank back), `insertInStack` pushes any other panel past the last pinned one (`pinnedFloor`), `dropSlotsPx` returns nothing for a pinned dragged panel and keeps the forbidden ranks as **empty** slots so a slot's index is still its rank, `hintedSides` drops its own side, `targetFor` strips the rank off a target, and `satelliteDragHandle` is inert when `canBeDragged` says a drag could not end anywhere. `reader-dock-demo`: the book tree and the contents are `floatable = false` + `reorderable = false` + `dockSides = setOf(Right)` — furniture, and no pane can be dropped in front of them. **Ranks**: `Docked.order` is kept contiguous from 0 per (host, side) by `dock()` / `undock()` (`dock(order)` inserts at that index, `null` = the rank the entry last held on that side, remembered in `SatelliteEntry.dockMemory`, else the end), and a side with panels publishes `DockDropZone.slots` — one rect per rank, cut at the neighbours' centres, the dragged panel excluded — so `DockTarget.order` is the rank under the pointer (`dockSlotAt`), drawn as an insertion bar (`insertionBarPx`), the own rank (`ownTarget`) being no target; a pointer over a stack beats a strip across its corner. `dropAt` converts a shown-rank into the full rank (closed panels keep theirs). The Wayland DnD path (`DockTransferTarget`) hit-tests the same published zones. A hand-driven `beginDrag` session must wait for the zones to be published before its first sample, or it resolves against the bare edges. `dock()` and the preview share one width (`dockSeedExtent`), so what lights up is what the release produces.

The rects come from `DockLayoutState.landingRectPx`: the side's measured band, inside existing layers, counting the dragged panel's own side as already freed; `hintedSides` drops the side the panel is alone on in that window, so it is neither drawn nor droppable. **`dockSides`**: `Satellite(dockSides = …)` (default all four, empty = floating-only) is fixed at declaration and enforced everywhere — `dock()` and `restore()` refuse another side, `hintedSides` and `DockZoneHints` neither draw nor publish it, the drag sessions resolve through `dockTargetFor(entry, …)` and the Wayland target filters on `drag.entry.dockSides`, and the default header hides its Dock action for a floating-only palette. **`floatable = false`** is the opposite knob — a fixed panel: `undock()` refuses it, a `restore()` that floats it is ignored, the docked drag publishes no tear-out ghost and a release off every zone leaves it in place, the default header drops its Float action, and the declaration requires a docked `initialPlacement`. **`reorderable = false`** pins the rank: `dock(order)` is ignored for it (it takes the declared rank back), `insertInStack` pushes any other panel past the last pinned one (`pinnedFloor`), `dropSlotsPx` returns nothing for a pinned dragged panel and keeps the forbidden ranks as **empty** slots so a slot's index is still its rank, `hintedSides` drops its own side, `targetFor` strips the rank off a target, and `satelliteDragHandle` is inert when `canBeDragged` says a drag could not end anywhere. **Telling the two gestures apart** (what an app adapts its UI to, #663 review): `TaoWindow.canPlaceOnScreen` is the public capability (branch on it, not on `isNativeWaylandSurface`), `SatelliteScope.isCompositorPlaced` is the same answer for the window the chrome is composed in (the floating scope reads the satellite's own window through a lambda since the scope outlives it; the docked scope reads `entry.dockHost`), `SatelliteCaptionStripWidth` + the `floatingCaption` slot of `Satellite` are the strip the title bar leaves to the compositor's move — reserved and composed **only** where `isCompositorPlaced`, so an app never has to guess a width or accidentally claim the only area that can move the palette — and `SatelliteWorkspace.dragKind` (`Window` / `Transfer`) says how a drag in flight is carried, which is what tells preview code whether `dragGhost` will ever be published. `reader-dock-demo`: the book tree and the contents are `floatable = false` + `reorderable = false` + `dockSides = setOf(Right)` — furniture, and no pane can be dropped in front of them. **Ranks**: `Docked.order` is kept contiguous from 0 per (host, side) by `dock()` / `undock()` (`dock(order)` inserts at that index, `null` = the rank the entry last held on that side, remembered in `SatelliteEntry.dockMemory`, else the end), and a side with panels publishes `DockDropZone.slots` — one rect per rank, cut at the neighbours' centres, the dragged panel excluded — so `DockTarget.order` is the rank under the pointer (`dockSlotAt`), drawn as an insertion bar (`insertionBarPx`), the own rank (`ownTarget`) being no target; a pointer over a stack beats a strip across its corner. `dropAt` converts a shown-rank into the full rank (closed panels keep theirs). The Wayland DnD path (`DockTransferTarget`) hit-tests the same published zones. A hand-driven `beginDrag` session must wait for the zones to be published before its first sample, or it resolves against the bare edges. `dock()` and the preview share one width (`dockSeedExtent`), so what lights up is what the release produces.

Composing it with the tab archetype needed a slot the tab windows did not have: `windowWrapper` wraps the whole window *including* its strip, so chrome hung there receives the strip inside its own content — the reader's tab strip landed in the middle of the dock and its panes climbed over the title bar. - `TabWindows(windowBodyWrapper = …)`, in tao and in `nucleus-application`: composed inside the window, below the strip, around the selected tab's body. Window-level chrome goes there — a `DockLayout` and its satellites, an activity bar — and it is one call site for every window, so a tab change neither rebuilds it nor moves the body's relocation keys. - `reader-dock-demo` is now both archetypes at once: each sefer is a tab, the strip is the top of the window, and everything under it is the reader. The dock belongs to the window, so a tab change only changes what the panes draw; a tab torn out arrives with a dock of its own, with its own widths and its own chapter. The books pane selects a tab, the contents pane drives the text, and what the reader remembers per book outlives every window. Covered by a real-window case: the chrome is under the strip, at the height it asked for, built exactly once per window, and neither a selection change nor a tear-off rebuilds it. Driven by hand on the demo too — tabs, tear-off, and the per-window panes. --- CLAUDE.md | 4 +- .../api/decorated-window-tao.api | 7 +- .../nucleusframework/window/tao/TabWindows.kt | 19 +- .../window/tao/headful/TabWorkspaceFixture.kt | 40 +++ .../tao/headful/TabWorkspaceHeadfulCases.kt | 67 +++- .../nucleusframework/readerdockdemo/Main.kt | 315 +++++++++++++----- .../readerdockdemo/ReaderState.kt | 173 ++++++++-- .../readerdockdemo/ReaderTabStrip.kt | 54 +++ .../api/nucleus-application.api | 14 +- .../dev/nucleusframework/application/Tab.kt | 9 + .../internal/TaoTabWorkspaceAdapter.kt | 9 + 11 files changed, 586 insertions(+), 125 deletions(-) create mode 100644 examples/reader-dock-demo/src/main/kotlin/dev/nucleusframework/readerdockdemo/ReaderTabStrip.kt diff --git a/CLAUDE.md b/CLAUDE.md index be71cf14a..1d08fa494 100644 --- a/CLAUDE.md +++ b/CLAUDE.md @@ -37,13 +37,13 @@ Published releases are `2.5.x` (latest tag `v2.5.0`).

Extents are fitted proportionally when the window is too small (`fit`). Drop feedback lives in `DockZoneHints.kt` and **the rectangles it draws are the target**: it publishes them to `HostGeometry.zoneBoundsInWindowPx`, and `dockTargetAt(draggedScreenRectPx, pointerScreenPx)` → `dockSideEntered` resolves a drop against those, not against the window's edges — on a layered side the strip is inset behind the existing layers, and the window's own edge behind them is nothing. A zone is entered when the dragged **satellite's** edge (its window, or the tear-out ghost) is within one zone thickness of the zone's outer edge and overlaps it across the other axis — edge alignment, not overlap, or a full-height panel could never be torn out; the pointer inside a zone is a second trigger and the tie-break, else the smallest gap wins.

This ports the state machine of `sh.calvin.reorderable`'s `ReorderableRow`, which is what SeforimApp uses. - **In hand**: tabs are `key`ed on their id, the dragged one is drawn at the pointer's travel since the grab, a neighbour steps a whole tab aside when that tab's *edge* crosses its *centre* (spring), and the release slides it into the slot it was over *before* the order changes — `pendingReorder` + `TabStripMotion.settle`, so nothing is ever seen jumping. Offsets are draw-time layer translations: the slots a drop resolves against never move. - **Two paths, by capability**: where the app places its windows the gesture stays `beginDrag` (ghost, screen hit-test) and the strip animates from the pointer it publishes. Where it cannot, the grip reorders *locally* — window px only — and hands the gesture to the platform's DnD session the moment the pointer leaves the strip (`TransferDragGesture`), which is the only way another window can be told where the pointer is and preview the drop. - `DragGhostWindow(popupFor = …)`: the preview is a popup overlay of the window it came from, so it follows the pointer out of a window the client cannot place. The tab slot carries `noWindowDrag()`, or the title bar's compositor move swallows the gesture. - Tabs open and close by width, the close button plays the tab out before the workspace drops it, and `insertionIndex` is direction-aware — a right-to-left strip used to resolve every drop mirrored. 90 real-window tab cases on X11 and 29 on native Wayland, including the numbers behind the motion, the RTL strip, the in-strip carry and the hand-over. --- CLAUDE.md | 2 +- .../api/decorated-window-tao.api | 13 +- .../window/tao/TabDragSessions.kt | 72 +++- .../nucleusframework/window/tao/TabStrip.kt | 153 ++++---- .../window/tao/TabStripAnimation.kt | 339 ++++++++++++++++ .../window/tao/TabStripDrag.kt | 259 ++++++++++++ .../nucleusframework/window/tao/TabWindows.kt | 10 +- .../window/tao/TabWorkspace.kt | 243 +++++++++++- .../window/tao/workspace/CrossWindowDrag.kt | 2 +- .../window/tao/workspace/DragGhostWindow.kt | 11 +- .../window/tao/workspace/TransferDrag.kt | 74 +++- .../window/tao/TabWorkspaceTest.kt | 26 ++ .../window/tao/TaoSceneTestBattery.kt | 3 + .../tao/headful/TabStripMotionHeadfulCases.kt | 369 ++++++++++++++++++ .../window/tao/headful/TabWorkspaceFixture.kt | 40 ++ .../tao/headful/TabWorkspaceHeadfulCases.kt | 37 +- .../headful/TabWorkspaceMotionHeadfulCases.kt | 32 +- .../headful/TabWorkspaceStressHeadfulCases.kt | 14 +- .../tao/headful/TaoHeadfulTestSuiteMain.kt | 1 + .../headful/WaylandWorkspaceHeadfulCases.kt | 91 +++++ .../nucleusframework/readerdockdemo/Main.kt | 9 +- 21 files changed, 1673 insertions(+), 127 deletions(-) create mode 100644 decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/TabStripAnimation.kt create mode 100644 decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/TabStripDrag.kt create mode 100644 decorated-window-tao/src/test/kotlin/dev/nucleusframework/window/tao/headful/TabStripMotionHeadfulCases.kt diff --git a/CLAUDE.md b/CLAUDE.md index 1d08fa494..97c2cca57 100644 --- a/CLAUDE.md +++ b/CLAUDE.md @@ -37,7 +37,7 @@ Published releases are `2.5.x` (latest tag `v2.5.0`).

Extents are fitted proportionally when the window is too small (`fit`). Drop feedback lives in `DockZoneHints.kt` and **the rectangles it draws are the target**: it publishes them to `HostGeometry.zoneBoundsInWindowPx`, and `dockTargetAt(draggedScreenRectPx, pointerScreenPx)` → `dockSideEntered` resolves a drop against those, not against the window's edges — on a layered side the strip is inset behind the existing layers, and the window's own edge behind them is nothing. A zone is entered when the dragged **satellite's** edge (its window, or the tear-out ghost) is within one zone thickness of the zone's outer edge and overlaps it across the other axis — edge alignment, not overlap, or a full-height panel could never be torn out; the pointer inside a zone is a second trigger and the tie-break, else the smallest gap wins. The rects come from `DockLayoutState.landingRectPx`: the side's measured band, inside existing layers, counting the dragged panel's own side as already freed; `hintedSides` drops the side the panel is alone on in that window, so it is neither drawn nor droppable. **`dockSides`**: `Satellite(dockSides = …)` (default all four, empty = floating-only) is fixed at declaration and enforced everywhere — `dock()` and `restore()` refuse another side, `hintedSides` and `DockZoneHints` neither draw nor publish it, the drag sessions resolve through `dockTargetFor(entry, …)` and the Wayland target filters on `drag.entry.dockSides`, and the default header hides its Dock action for a floating-only palette. **`floatable = false`** is the opposite knob — a fixed panel: `undock()` refuses it, a `restore()` that floats it is ignored, the docked drag publishes no tear-out ghost and a release off every zone leaves it in place, the default header drops its Float action, and the declaration requires a docked `initialPlacement`. **`reorderable = false`** pins the rank: `dock(order)` is ignored for it (it takes the declared rank back), `insertInStack` pushes any other panel past the last pinned one (`pinnedFloor`), `dropSlotsPx` returns nothing for a pinned dragged panel and keeps the forbidden ranks as **empty** slots so a slot's index is still its rank, `hintedSides` drops its own side, `targetFor` strips the rank off a target, and `satelliteDragHandle` is inert when `canBeDragged` says a drag could not end anywhere. **Telling the two gestures apart** (what an app adapts its UI to, #663 review): `TaoWindow.canPlaceOnScreen` is the public capability (branch on it, not on `isNativeWaylandSurface`), `SatelliteScope.isCompositorPlaced` is the same answer for the window the chrome is composed in (the floating scope reads the satellite's own window through a lambda since the scope outlives it; the docked scope reads `entry.dockHost`), `SatelliteCaptionStripWidth` + the `floatingCaption` slot of `Satellite` are the strip the title bar leaves to the compositor's move — reserved and composed **only** where `isCompositorPlaced`, so an app never has to guess a width or accidentally claim the only area that can move the palette — and `SatelliteWorkspace.dragKind` (`Window` / `Transfer`) says how a drag in flight is carried, which is what tells preview code whether `dragGhost` will ever be published. `reader-dock-demo`: the book tree and the contents are `floatable = false` + `reorderable = false` + `dockSides = setOf(Right)` — furniture, and no pane can be dropped in front of them. **Ranks**: `Docked.order` is kept contiguous from 0 per (host, side) by `dock()` / `undock()` (`dock(order)` inserts at that index, `null` = the rank the entry last held on that side, remembered in `SatelliteEntry.dockMemory`, else the end), and a side with panels publishes `DockDropZone.slots` — one rect per rank, cut at the neighbours' centres, the dragged panel excluded — so `DockTarget.order` is the rank under the pointer (`dockSlotAt`), drawn as an insertion bar (`insertionBarPx`), the own rank (`ownTarget`) being no target; a pointer over a stack beats a strip across its corner. `dropAt` converts a shown-rank into the full rank (closed panels keep theirs). The Wayland DnD path (`DockTransferTarget`) hit-tests the same published zones. A hand-driven `beginDrag` session must wait for the zones to be published before its first sample, or it resolves against the bare edges. `dock()` and the preview share one width (`dockSeedExtent`), so what lights up is what the release produces. Headful coverage: `DockLayoutHeadfulCases` (robot splitter drags) + `DockLayoutMonkeyHeadfulCases` (profiles × seeds, `-Dnucleus.tao.headful.filter="dock layout"`). +- `decorated-window-tao` internals: `window/tao/workspace/` is the shared, `internal` core behind the multi-window archetypes — `WindowGroup` (membership, focus recency, pinning), `RelocatedContentHost` + `RelocatingSaveableStateRegistry` (`rememberSaveable` state that follows content between windows), `HostGeometry` (drop targets in physical screen px), `CrossWindowDrag` (one live drag, screen-space drag handle), `DragGhostWindow`, `ScreenPlacement` (the public capability is `TaoWindow.canPlaceOnScreen` — the native-Wayland gate — GDK reports every toplevel at `(0, 0)` and ignores moves, so anything that treats `outerBoundsPx()`'s origin as a screen coordinate must check it; the size half stays valid there; `warnScreenPlacementUnsupported` logs the gap once per process), `TransferDrag` (the native-Wayland path of every cross-window gesture: the grip starts a platform **drag-and-drop** session carrying an in-process token (`TaoPrivateTransfer`, `SAME_APP` only), the window under the pointer resolves the drop in its *own* coordinates and records it on the session, and the source acts on that record when the session ends — inverted roles versus `ScreenDrag`, because the source is told nothing about where the pointer is; the drag icon is a reduced snapshot of the dragged palette or panel, taken through `TaoWindow.contentSnapshot`). **Tab drag, two paths.** Where the app places its windows the gesture is `screenDragHandle` → `TabWorkspace.beginDrag` (ghost window, screen hit-test, tear-off), and the strip animates the reorder from `dragPointerScreenPx`. Where it cannot (native Wayland), the grip is `tabStripLocalDragHandle`: a **local** reorder driven by the pointer's travel in window px and resolved by `reorderTarget` (edge-crossing, RTL inferred from the slots), and the moment the pointer leaves the strip the gesture is handed to the platform's drag-and-drop session — `transferDragHandle(gesture = …)` takes a `TransferDragGesture` whose `onDrag` returns `true` to start it mid-gesture, from the *press* position (Compose refuses a point outside the source node). That handover is what gives every *other* window the pointer in its own coordinates, so their strips can preview the drop; nothing else can, since a client hears nothing about a pointer another window holds. `DragGhostWindow(popupFor = source)` is the preview that follows the pointer out of a compositor-placed window (`wl_subsurface`, parent-relative positions). The tab slot carries `noWindowDrag()`: the title bar's move is a compositor grab that swallows the gesture. **`TabStrip` motion** (`TabStripAnimation.kt`, a port of `sh.calvin.reorderable`'s `ReorderableRow` state machine): items are `key`ed on the tab id; a tab dragged along its **own** strip publishes no ghost (`TabTearOffDragSession` clears it while `dropPreview.group === entry.group`) and the strip draws it at the pointer's travel since the grab (`TabWorkspace.dragGrabScreenPx` / `dragPointerScreenPx`), a neighbour slides one tab-width aside (spring `StiffnessMediumLow`) when the carried tab's *edge* crosses its *centre*, and on release the session sets `pendingReorder` instead of reordering — the strip's `TabStripMotion.settle` slides the tab into the target slot, then `reorder()` + `rest()` in the same frame, so nothing jumps. The own-strip drop index is `reorderTarget` (edge-crossing rule, RTL inferred from the slots, same rule as the motion) and `insertionIndex` is direction-aware too (a right-to-left strip used to resolve every drop mirrored). Offsets are draw-time `graphicsLayer` translations, so `tabSlot` geometry is always the settled layout. Tabs open/close by width (`AnimatedVisibility`, 200 ms, `clip = false` so the carried card can leave its slot) and the stock close button delays `workspace.close` by the exit duration; `TabEntry.isEntering` marks a tab the strip has not shown yet. `TabWindows` has two app slots: `windowWrapper` wraps the whole window *including* its strip (per-window locals, background), `windowBodyWrapper` wraps only what is under the strip and is where window-level chrome goes (a `DockLayout`, activity bars) — composed at one call site for every window, so a tab change neither rebuilds it nor moves the body's relocation keys. `SatelliteWorkspace` (docking) and `TabWorkspace` (Chrome-like tabs) are both built on it — put new cross-window gestures there rather than duplicating the geometry or the drag bookkeeping. `DockLayout` (`window/tao/DockLayout.kt` + `DockSplitter.kt` + `DockTransferTarget.kt`) is the dock: sides nest in `sideOrder` (outermost first, default `DefaultDockSideOrder` = top, bottom, left, right — **not** `DockSide.entries`, whose declaration order is left, right, top, bottom), a side is either *split* (panels share its length by `Docked.weight` and its thickness by `dockExtent(side)`) or *layered* (`layeredSides`: each panel a full-length layer of its own `Docked.extent`, the way a nested split-pane tree looks), `splitter` / `panel` slots carry the app's own chrome (`DockSplitterScope.dockSplitterHandle()` is the gesture; an overflowing `requiredWidth` grip on a 1 dp line works), sides are physical and the layout forces LTR internally then restores the caller's direction for content/panels/slots, and every panel and the content are `movableContentOf` so no layout change (extent, weight, order, side, restore, side order, direction) rebuilds a subtree — the layout's inputs live in `DockLayoutState` as snapshot state because the bands are separate composables that strong skipping would otherwise skip.

Where it cannot (native Wayland), the grip is `tabStripLocalDragHandle`: a **local** reorder driven by the pointer's travel in window px and resolved by `reorderTarget` (edge-crossing, RTL inferred from the slots), and the moment the pointer leaves the strip the gesture is handed to the platform's drag-and-drop session — `transferDragHandle(gesture = …)` takes a `TransferDragGesture` whose `onDrag` returns `true` to start it mid-gesture, from the *press* position (Compose refuses a point outside the source node). That handover is what gives every *other* window the pointer in its own coordinates, so their strips can preview the drop; nothing else can, since a client hears nothing about a pointer another window holds. `DragGhostWindow(popupFor = source)` is the preview that follows the pointer out of a compositor-placed window (`wl_subsurface`, parent-relative positions). The tab slot carries `noWindowDrag()`: the title bar's move is a compositor grab that swallows the gesture. **`TabStrip` motion** (`TabStripAnimation.kt`, a port of `sh.calvin.reorderable`'s `ReorderableRow` state machine): items are `key`ed on the tab id; a tab dragged along its **own** strip publishes no ghost (`TabTearOffDragSession` clears it while `dropPreview.group === entry.group`) and the strip draws it at the pointer's travel since the grab (`TabWorkspace.dragGrabScreenPx` / `dragPointerScreenPx`), a neighbour slides one tab-width aside (spring `StiffnessMediumLow`) when the carried tab's *edge* crosses its *centre*, and on release the session sets `pendingReorder` instead of reordering — the strip's `TabStripMotion.settle` slides the tab into the target slot, then `reorder()` + `rest()` in the same frame, so nothing jumps. The own-strip drop index is `reorderTarget` (edge-crossing rule, RTL inferred from the slots, same rule as the motion) and `insertionIndex` is direction-aware too (a right-to-left strip used to resolve every drop mirrored). Offsets are draw-time `graphicsLayer` translations, so `tabSlot` geometry is always the settled layout. Tabs open/close by width (`AnimatedVisibility`, 200 ms, `clip = false` so the carried card can leave its slot) and the stock close button delays `workspace.close` by the exit duration; `TabEntry.isEntering` marks a tab the strip has not shown yet. `TabWindows` has two app slots: `windowWrapper` wraps the whole window *including* its strip (per-window locals, background), `windowBodyWrapper` wraps only what is under the strip and is where window-level chrome goes (a `DockLayout`, activity bars) — composed at one call site for every window, so a tab change neither rebuilds it nor moves the body's relocation keys. `SatelliteWorkspace` (docking) and `TabWorkspace` (Chrome-like tabs) are both built on it — put new cross-window gestures there rather than duplicating the geometry or the drag bookkeeping. `DockLayout` (`window/tao/DockLayout.kt` + `DockSplitter.kt` + `DockTransferTarget.kt`) is the dock: sides nest in `sideOrder` (outermost first, default `DefaultDockSideOrder` = top, bottom, left, right — **not** `DockSide.entries`, whose declaration order is left, right, top, bottom), a side is either *split* (panels share its length by `Docked.weight` and its thickness by `dockExtent(side)`) or *layered* (`layeredSides`: each panel a full-length layer of its own `Docked.extent`, the way a nested split-pane tree looks), `splitter` / `panel` slots carry the app's own chrome (`DockSplitterScope.dockSplitterHandle()` is the gesture; an overflowing `requiredWidth` grip on a 1 dp line works), sides are physical and the layout forces LTR internally then restores the caller's direction for content/panels/slots, and every panel and the content are `movableContentOf` so no layout change (extent, weight, order, side, restore, side order, direction) rebuilds a subtree — the layout's inputs live in `DockLayoutState` as snapshot state because the bands are separate composables that strong skipping would otherwise skip. Extents are fitted proportionally when the window is too small (`fit`). Drop feedback lives in `DockZoneHints.kt` and **the rectangles it draws are the target**: it publishes them to `HostGeometry.zoneBoundsInWindowPx`, and `dockTargetAt(draggedScreenRectPx, pointerScreenPx)` → `dockSideEntered` resolves a drop against those, not against the window's edges — on a layered side the strip is inset behind the existing layers, and the window's own edge behind them is nothing. A zone is entered when the dragged **satellite's** edge (its window, or the tear-out ghost) is within one zone thickness of the zone's outer edge and overlaps it across the other axis — edge alignment, not overlap, or a full-height panel could never be torn out; the pointer inside a zone is a second trigger and the tie-break, else the smallest gap wins. The rects come from `DockLayoutState.landingRectPx`: the side's measured band, inside existing layers, counting the dragged panel's own side as already freed; `hintedSides` drops the side the panel is alone on in that window, so it is neither drawn nor droppable. **`dockSides`**: `Satellite(dockSides = …)` (default all four, empty = floating-only) is fixed at declaration and enforced everywhere — `dock()` and `restore()` refuse another side, `hintedSides` and `DockZoneHints` neither draw nor publish it, the drag sessions resolve through `dockTargetFor(entry, …)` and the Wayland target filters on `drag.entry.dockSides`, and the default header hides its Dock action for a floating-only palette. **`floatable = false`** is the opposite knob — a fixed panel: `undock()` refuses it, a `restore()` that floats it is ignored, the docked drag publishes no tear-out ghost and a release off every zone leaves it in place, the default header drops its Float action, and the declaration requires a docked `initialPlacement`. **`reorderable = false`** pins the rank: `dock(order)` is ignored for it (it takes the declared rank back), `insertInStack` pushes any other panel past the last pinned one (`pinnedFloor`), `dropSlotsPx` returns nothing for a pinned dragged panel and keeps the forbidden ranks as **empty** slots so a slot's index is still its rank, `hintedSides` drops its own side, `targetFor` strips the rank off a target, and `satelliteDragHandle` is inert when `canBeDragged` says a drag could not end anywhere. **Telling the two gestures apart** (what an app adapts its UI to, #663 review): `TaoWindow.canPlaceOnScreen` is the public capability (branch on it, not on `isNativeWaylandSurface`), `SatelliteScope.isCompositorPlaced` is the same answer for the window the chrome is composed in (the floating scope reads the satellite's own window through a lambda since the scope outlives it; the docked scope reads `entry.dockHost`), `SatelliteCaptionStripWidth` + the `floatingCaption` slot of `Satellite` are the strip the title bar leaves to the compositor's move — reserved and composed **only** where `isCompositorPlaced`, so an app never has to guess a width or accidentally claim the only area that can move the palette — and `SatelliteWorkspace.dragKind` (`Window` / `Transfer`) says how a drag in flight is carried, which is what tells preview code whether `dragGhost` will ever be published. `reader-dock-demo`: the book tree and the contents are `floatable = false` + `reorderable = false` + `dockSides = setOf(Right)` — furniture, and no pane can be dropped in front of them. **Ranks**: `Docked.order` is kept contiguous from 0 per (host, side) by `dock()` / `undock()` (`dock(order)` inserts at that index, `null` = the rank the entry last held on that side, remembered in `SatelliteEntry.dockMemory`, else the end), and a side with panels publishes `DockDropZone.slots` — one rect per rank, cut at the neighbours' centres, the dragged panel excluded — so `DockTarget.order` is the rank under the pointer (`dockSlotAt`), drawn as an insertion bar (`insertionBarPx`), the own rank (`ownTarget`) being no target; a pointer over a stack beats a strip across its corner. `dropAt` converts a shown-rank into the full rank (closed panels keep theirs). The Wayland DnD path (`DockTransferTarget`) hit-tests the same published zones. A hand-driven `beginDrag` session must wait for the zones to be published before its first sample, or it resolves against the bare edges. `dock()` and the preview share one width (`dockSeedExtent`), so what lights up is what the release produces. Headful coverage: `DockLayoutHeadfulCases` (robot splitter drags) + `DockLayoutMonkeyHeadfulCases` (profiles × seeds, `-Dnucleus.tao.headful.filter="dock layout"`). +- `decorated-window-tao` internals: `window/tao/workspace/` is the shared, `internal` core behind the multi-window archetypes — `WindowGroup` (membership, focus recency, pinning), `RelocatedContentHost` + `RelocatingSaveableStateRegistry` (`rememberSaveable` state that follows content between windows), `HostGeometry` (drop targets in physical screen px), `CrossWindowDrag` (one live drag, screen-space drag handle), `DragGhostWindow`, `ScreenPlacement` (the public capability is `TaoWindow.canPlaceOnScreen` — the native-Wayland gate — GDK reports every toplevel at `(0, 0)` and ignores moves, so anything that treats `outerBoundsPx()`'s origin as a screen coordinate must check it; the size half stays valid there; `warnScreenPlacementUnsupported` logs the gap once per process), `TransferDrag` (the native-Wayland path of every cross-window gesture: the grip starts a platform **drag-and-drop** session carrying an in-process token (`TaoPrivateTransfer`, `SAME_APP` only), the window under the pointer resolves the drop in its *own* coordinates and records it on the session, and the source acts on that record when the session ends — inverted roles versus `ScreenDrag`, because the source is told nothing about where the pointer is; the drag icon is a reduced snapshot of the dragged palette or panel, taken through `TaoWindow.contentSnapshot`). **Tab drag, two paths.** Where the app places its windows the gesture is `screenDragHandle` → `TabWorkspace.beginDrag` (ghost window, screen hit-test, tear-off), and the strip animates the reorder from `dragPointerScreenPx`. Where it cannot (native Wayland), the grip is `tabStripLocalDragHandle`: a **local** reorder driven by the pointer's travel in window px and resolved by `reorderTarget` (edge-crossing, RTL inferred from the slots), and the moment the pointer leaves the strip the gesture is handed to the platform's drag-and-drop session — `transferDragHandle(gesture = …)` takes a `TransferDragGesture` whose `onDrag` returns `true` to start it mid-gesture, from the *press* position (Compose refuses a point outside the source node). That handover is what gives every *other* window the pointer in its own coordinates, so their strips can preview the drop; nothing else can, since a client hears nothing about a pointer another window holds. `DragGhostWindow(popupFor = source)` is the preview that follows the pointer out of a compositor-placed window (`wl_subsurface`, parent-relative positions). The tab slot carries `noWindowDrag()`: the title bar's move is a compositor grab that swallows the gesture. **`TabStrip` motion** (`TabStripAnimation.kt`, a port of `sh.calvin.reorderable`'s `ReorderableRow` state machine): items are `key`ed on the tab id; a tab dragged along its **own** strip publishes no ghost (`TabTearOffDragSession` clears it while `dropPreview.group === entry.group`) and the strip draws it at the pointer's travel since the grab (`TabWorkspace.dragGrabScreenPx` / `dragPointerScreenPx`), a neighbour slides one tab-width aside (spring `StiffnessMediumLow`) when the carried tab's *edge* crosses its *centre*, and on release the session sets `pendingReorder` instead of reordering — the strip's `TabStripMotion.settle` slides the tab into the target slot, then `reorder()` + `rest()` in the same frame, so nothing jumps. The own-strip drop index is `reorderTarget` (edge-crossing rule, RTL inferred from the slots, same rule as the motion) and `insertionIndex` is direction-aware too (a right-to-left strip used to resolve every drop mirrored). Offsets are draw-time `graphicsLayer` translations, so `tabSlot` geometry is always the settled layout. Tabs open/close by width (`AnimatedVisibility`, 200 ms, `clip = false` so the carried card can leave its slot) and the stock close button delays `workspace.close` by the exit duration; `TabEntry.isEntering` marks a tab the strip has not shown yet. `TabWindows` has two app slots: `windowWrapper` wraps the whole window *including* its strip (per-window locals, background), `windowBodyWrapper` wraps only what is under the strip and is where window-level chrome goes (a `DockLayout`, activity bars) — composed at one call site for every window, so a tab change neither rebuilds it nor moves the body's relocation keys. `SatelliteWorkspace` (docking) and `TabWorkspace` (Chrome-like tabs) are both built on it — put new cross-window gestures there rather than duplicating the geometry or the drag bookkeeping. `DockLayout` (`window/tao/DockLayout.kt` + `DockSplitter.kt` + `DockTransferTarget.kt`) is the dock: sides nest in `sideOrder` (outermost first, default `DefaultDockSideOrder` = top, bottom, left, right — **not** `DockSide.entries`, whose declaration order is left, right, top, bottom), a side is either *split* (panels share its length by `Docked.weight` and its thickness by `dockExtent(side)`) or *layered* (`layeredSides`: each panel a full-length layer of its own `Docked.extent`, the way a nested split-pane tree looks), `splitter` / `panel` slots carry the app's own chrome (`DockSplitterScope.dockSplitterHandle()` is the gesture; an overflowing `requiredWidth` grip on a 1 dp line works), sides are physical and the layout forces LTR internally then restores the caller's direction for content/panels/slots, and every panel and the content are `movableContentOf` so no layout change (extent, weight, order, side, restore, side order, direction) rebuilds a subtree — the layout's inputs live in `DockLayoutState` as snapshot state because the bands are separate composables that strong skipping would otherwise skip. Extents are fitted proportionally when the window is too small (`fit`). Drop feedback lives in `DockZoneHints.kt` and **the rectangles it draws are the target**: it publishes them to `HostGeometry.zoneBoundsInWindowPx`, and `dockTargetAt(draggedScreenRectPx, pointerScreenPx)` → `dockSideEntered` resolves a drop against those, not against the window's edges — on a layered side the strip is inset behind the existing layers, and the window's own edge behind them is nothing. A zone is entered when the dragged **satellite's** edge (its window, or the tear-out ghost) is within one zone thickness of the zone's outer edge and overlaps it across the other axis — edge alignment, not overlap, or a full-height panel could never be torn out; the pointer inside a zone is a second trigger and the tie-break, else the smallest gap wins. The rects come from `DockLayoutState.landingRectPx`: the side's measured band, inside existing layers, counting the dragged panel's own side as already freed; `hintedSides` drops the side the panel is alone on in that window, so it is neither drawn nor droppable. **`dockSides`**: `Satellite(dockSides = …)` (default all four, empty = floating-only) is fixed at declaration and enforced everywhere — `dock()` and `restore()` refuse another side, `hintedSides` and `DockZoneHints` neither draw nor publish it, the drag sessions resolve through `dockTargetFor(entry, …)` and the Wayland target filters on `drag.entry.dockSides`, and the default header hides its Dock action for a floating-only palette. **`floatable = false`** is the opposite knob — a fixed panel: `undock()` refuses it, a `restore()` that floats it is ignored, the docked drag publishes no tear-out ghost and a release off every zone leaves it in place, the default header drops its Float action, and the declaration requires a docked `initialPlacement`. **`reorderable = false`** pins the rank: `dock(order)` is ignored for it (it takes the declared rank back), `insertInStack` pushes any other panel past the last pinned one (`pinnedFloor`), `dropSlotsPx` returns nothing for a pinned dragged panel and keeps the forbidden ranks as **empty** slots so a slot's index is still its rank, `hintedSides` drops its own side, `targetFor` strips the rank off a target, and `satelliteDragHandle` is inert when `canBeDragged` says a drag could not end anywhere. **Telling the two gestures apart** (what an app adapts its UI to, #663 review): `TaoWindow.canPlaceOnScreen` is the public capability (branch on it, not on `isNativeWaylandSurface`), `SatelliteScope.isCompositorPlaced` is the same answer for the window the chrome is composed in (the floating scope reads the satellite's own window through a lambda since the scope outlives it; the docked scope reads `entry.dockHost`), `SatelliteCaptionStripWidth` + the `floatingCaption` slot of `Satellite` are the strip the title bar leaves to the compositor's move — reserved and composed **only** where `isCompositorPlaced`, so an app never has to guess a width or accidentally claim the only area that can move the palette — and `SatelliteWorkspace.dragKind` (`Window` / `Transfer`) says how a drag in flight is carried, which is what tells preview code whether `dragGhost` will ever be published. `reader-dock-demo`: the book tree and the contents are `floatable = false` + `reorderable = false` + `dockSides = setOf(Right)` — furniture, and no pane can be dropped in front of them. **Ranks**: `Docked.order` is kept contiguous from 0 per (host, side) by `dock()` / `undock()` (`dock(order)` inserts at that index, `null` = the rank the entry last held on that side, remembered in `SatelliteEntry.dockMemory`, else the end), and a side with panels publishes `DockDropZone.slots` — one rect per rank, cut at the neighbours' centres, the dragged panel excluded — so `DockTarget.order` is the rank under the pointer (`dockSlotAt`), the own rank (`ownTarget`) being no target; a pointer over a stack beats a strip across its corner. `dropAt` converts a shown-rank into the full rank (closed panels keep theirs).

A hand-driven `beginDrag` session must wait for the zones to be published before its first sample, or it resolves against the bare edges. `dock()` and the preview share one width (`dockSeedExtent`) and one weight (`dockSeedWeight`), so what lights up is what the release produces. **One drop preview everywhere** (`DragPreviewDefaults.kt`): the card that follows the pointer (`SatelliteGhostCard` / `TabGhostCard` on `DragPreviewSurface`) is also drawn on the space the release fills — the dock draws it at `DockLayoutState.dropRectPx(side, dragged, order, extentPx)` (empty side: the edge strip; layered: the layer at that rank; split: the share the re-divided weights give it, dividers counted), the tab strip opens a slot of the dragged tab's width (`TabStripScope.dropGhost` → `TabDropGhost`, `TabDropGhostCard`; `TabWorkspace.draggedTabWidth` reads the source slot) — and the sides merely on offer are the same surface at `hint` intensity. No insertion bars, no drop-indicator lines; a custom strip draws `dropGhost` itself, as `jewel-tabs-demo` does with a placeholder `TabData.Editor`.

Where it cannot (native Wayland), the grip is `tabStripLocalDragHandle`: a **local** reorder driven by the pointer's travel in window px and resolved by `reorderTarget` (edge-crossing, RTL inferred from the slots), and the moment the pointer leaves the strip the gesture is handed to the platform's drag-and-drop session — `transferDragHandle(gesture = …)` takes a `TransferDragGesture` whose `onDrag` returns `true` to start it mid-gesture, from the *press* position (Compose refuses a point outside the source node). That handover is what gives every *other* window the pointer in its own coordinates, so their strips can preview the drop; nothing else can, since a client hears nothing about a pointer another window holds. `DragGhostWindow(popupFor = source)` is the preview that follows the pointer out of a compositor-placed window (`wl_subsurface`, parent-relative positions). The tab slot carries `noWindowDrag()`: the title bar's move is a compositor grab that swallows the gesture. **`TabStrip` motion** (`TabStripAnimation.kt`, a port of `sh.calvin.reorderable`'s `ReorderableRow` state machine): items are `key`ed on the tab id; a tab dragged along its **own** strip publishes no ghost (`TabTearOffDragSession` clears it while `dropPreview.group === entry.group`) and the strip draws it at the pointer's travel since the grab (`TabWorkspace.dragGrabScreenPx` / `dragPointerScreenPx`), a neighbour slides one tab-width aside (spring `StiffnessMediumLow`) when the carried tab's *edge* crosses its *centre*, and on release the session sets `pendingReorder` instead of reordering — the strip's `TabStripMotion.settle` slides the tab into the target slot, then `reorder()` + `rest()` in the same frame, so nothing jumps. The own-strip drop index is `reorderTarget` (edge-crossing rule, RTL inferred from the slots, same rule as the motion) and `insertionIndex` is direction-aware too (a right-to-left strip used to resolve every drop mirrored). Offsets are draw-time `graphicsLayer` translations, so `tabSlot` geometry is always the settled layout. Tabs open/close by width (`AnimatedVisibility`, 200 ms, `clip = false` so the carried card can leave its slot) and the stock close button delays `workspace.close` by the exit duration; `TabEntry.isEntering` marks a tab the strip has not shown yet. `TabWindows` has two app slots: `windowWrapper` wraps the whole window *including* its strip (per-window locals, background), `windowBodyWrapper` wraps only what is under the strip and is where window-level chrome goes (a `DockLayout`, activity bars) — composed at one call site for every window, so a tab change neither rebuilds it nor moves the body's relocation keys. `SatelliteWorkspace` (docking) and `TabWorkspace` (Chrome-like tabs) are both built on it — put new cross-window gestures there rather than duplicating the geometry or the drag bookkeeping. `DockLayout` (`window/tao/DockLayout.kt` + `DockSplitter.kt` + `DockTransferTarget.kt`) is the dock: sides nest in `sideOrder` (outermost first, default `DefaultDockSideOrder` = top, bottom, left, right — **not** `DockSide.entries`, whose declaration order is left, right, top, bottom), a side is either *split* (panels share its length by `Docked.weight` and its thickness by `dockExtent(side)`) or *layered* (`layeredSides`: each panel a full-length layer of its own `Docked.extent`, the way a nested split-pane tree looks), `splitter` / `panel` slots carry the app's own chrome (`DockSplitterScope.dockSplitterHandle()` is the gesture; an overflowing `requiredWidth` grip on a 1 dp line works), sides are physical and the layout forces LTR internally then restores the caller's direction for content/panels/slots, and every panel and the content are `movableContentOf` so no layout change (extent, weight, order, side, restore, side order, direction) rebuilds a subtree — the layout's inputs live in `DockLayoutState` as snapshot state because the bands are separate composables that strong skipping would otherwise skip. Extents are fitted proportionally when the window is too small (`fit`). Drop feedback lives in `DockZoneHints.kt` and **the rectangles it draws are the target**: it publishes them to `HostGeometry.zoneBoundsInWindowPx`, and `dockTargetAt(draggedScreenRectPx, pointerScreenPx)` → `dockSideEntered` resolves a drop against those, not against the window's edges — on a layered side the strip is inset behind the existing layers, and the window's own edge behind them is nothing. A zone is entered when the dragged **satellite's** edge (its window, or the tear-out ghost) is within one zone thickness of the zone's outer edge and overlaps it across the other axis — edge alignment, not overlap, or a full-height panel could never be torn out; the pointer inside a zone is a second trigger and the tie-break, else the smallest gap wins. The rects come from `DockLayoutState.landingRectPx`: the side's measured band, inside existing layers, counting the dragged panel's own side as already freed; `hintedSides` drops the side the panel is alone on in that window, so it is neither drawn nor droppable. **`dockSides`**: `Satellite(dockSides = …)` (default all four, empty = floating-only) is fixed at declaration and enforced everywhere — `dock()` and `restore()` refuse another side, `hintedSides` and `DockZoneHints` neither draw nor publish it, the drag sessions resolve through `dockTargetFor(entry, …)` and the Wayland target filters on `drag.entry.dockSides`, and the default header hides its Dock action for a floating-only palette. **`floatable = false`** is the opposite knob — a fixed panel: `undock()` refuses it, a `restore()` that floats it is ignored, the docked drag publishes no tear-out ghost and a release off every zone leaves it in place, the default header drops its Float action, and the declaration requires a docked `initialPlacement`. **`reorderable = false`** pins the rank: `dock(order)` is ignored for it (it takes the declared rank back), `insertInStack` pushes any other panel past the last pinned one (`pinnedFloor`), `dropSlotsPx` returns nothing for a pinned dragged panel and keeps the forbidden ranks as **empty** slots so a slot's index is still its rank, `hintedSides` drops its own side, `targetFor` strips the rank off a target, and `satelliteDragHandle` is inert when `canBeDragged` says a drag could not end anywhere. **Telling the two gestures apart** (what an app adapts its UI to, #663 review): `TaoWindow.canPlaceOnScreen` is the public capability (branch on it, not on `isNativeWaylandSurface`), `SatelliteScope.isCompositorPlaced` is the same answer for the window the chrome is composed in (the floating scope reads the satellite's own window through a lambda since the scope outlives it; the docked scope reads `entry.dockHost`), `SatelliteCaptionStripWidth` + the `floatingCaption` slot of `Satellite` are the strip the title bar leaves to the compositor's move — reserved and composed **only** where `isCompositorPlaced`, so an app never has to guess a width or accidentally claim the only area that can move the palette — and `SatelliteWorkspace.dragKind` (`Window` / `Transfer`) says how a drag in flight is carried, which is what tells preview code whether `dragGhost` will ever be published. `reader-dock-demo`: the book tree and the contents are `floatable = false` + `reorderable = false` + `dockSides = setOf(Right)` — furniture, and no pane can be dropped in front of them. **Ranks**: `Docked.order` is kept contiguous from 0 per (host, side) by `dock()` / `undock()` (`dock(order)` inserts at that index, `null` = the rank the entry last held on that side, remembered in `SatelliteEntry.dockMemory`, else the end), and a side with panels publishes `DockDropZone.slots` — one rect per rank, cut at the neighbours' centres, the dragged panel excluded — so `DockTarget.order` is the rank under the pointer (`dockSlotAt`), the own rank (`ownTarget`) being no target; a pointer over a stack beats a strip across its corner. `dropAt` converts a shown-rank into the full rank (closed panels keep theirs). The Wayland DnD path (`DockTransferTarget`) hit-tests the same published zones. A hand-driven `beginDrag` session must wait for the zones to be published before its first sample, or it resolves against the bare edges. `dock()` and the preview share one width (`dockSeedExtent`) and one weight (`dockSeedWeight`), so what lights up is what the release produces. **One drop preview everywhere** (`DragPreviewDefaults.kt`): the card that follows the pointer (`SatelliteGhostCard` / `TabGhostCard` on `DragPreviewSurface`) is also drawn on the space the release fills — the dock draws it at `DockLayoutState.dropRectPx(side, dragged, order, extentPx)` (empty side: the edge strip; layered: the layer at that rank; split: the share the re-divided weights give it, dividers counted), the tab strip opens a slot of the dragged tab's width (`TabStripScope.dropGhost` → `TabDropGhost`, `TabDropGhostCard`; `TabWorkspace.draggedTabWidth` reads the source slot) — and the sides merely on offer are the same surface at `hint` intensity. No insertion bars, no drop-indicator lines; a custom strip draws `dropGhost` itself, as `jewel-tabs-demo` does with a placeholder `TabData.Editor`. Headful coverage: `DockLayoutHeadfulCases` (robot splitter drags) + `DockLayoutMonkeyHeadfulCases` (profiles × seeds, `-Dnucleus.tao.headful.filter="dock layout"`). +- `decorated-window-tao` internals: `window/tao/workspace/` is the shared, `internal` core behind the multi-window archetypes — `WindowGroup` (membership, focus recency, pinning), `RelocatedContentHost` + `RelocatingSaveableStateRegistry` (`rememberSaveable` state that follows content between windows), `HostGeometry` (drop targets in physical screen px), `CrossWindowDrag` (one live drag, screen-space drag handle), `DragGhostWindow`, `ScreenPlacement` (the public capability is `TaoWindow.canPlaceOnScreen` — the native-Wayland gate — GDK reports every toplevel at `(0, 0)` and ignores moves, so anything that treats `outerBoundsPx()`'s origin as a screen coordinate must check it; the size half stays valid there; `warnScreenPlacementUnsupported` logs the gap once per process), `TransferDrag` (the native-Wayland path of every cross-window gesture: the grip starts a platform **drag-and-drop** session carrying an in-process token (`TaoPrivateTransfer`, `SAME_APP` only), the window under the pointer resolves the drop in its *own* coordinates and records it on the session, and the source acts on that record when the session ends — inverted roles versus `ScreenDrag`, because the source is told nothing about where the pointer is; the drag icon is a reduced snapshot of the dragged palette or panel, taken through `TaoWindow.contentSnapshot`). **Tab drag, two paths.** Where the app places its windows the gesture is `screenDragHandle` → `TabWorkspace.beginDrag` (ghost window, screen hit-test, tear-off; the drop resolves through `dropTargetAt(draggedScreenRectPx, pointerScreenPx, …)` — a strip the **card** has reached counts as entered, the pointer's own strip still winning, the same rule as the dock zones, and a single-tab window's drag hands its own strip band as the card), and the strip animates the reorder from `dragPointerScreenPx`. Where it cannot (native Wayland), the grip is `tabStripLocalDragHandle`: a **local** reorder driven by the pointer's travel in window px and resolved by `reorderTarget` (edge-crossing, RTL inferred from the slots), and the moment the pointer leaves the strip the gesture is handed to the platform's drag-and-drop session — `transferDragHandle(gesture = …)` takes a `TransferDragGesture` whose `onDrag` returns `true` to start it mid-gesture, from the *press* position (Compose refuses a point outside the source node). That handover is what gives every *other* window the pointer in its own coordinates, so their strips can preview the drop; nothing else can, since a client hears nothing about a pointer another window holds. `DragGhostWindow(popupFor = source)` is the preview that follows the pointer out of a compositor-placed window (`wl_subsurface`, parent-relative positions). The tab slot carries `noWindowDrag()`: the title bar's move is a compositor grab that swallows the gesture. **`TabStrip` motion** (`TabStripAnimation.kt`, a port of `sh.calvin.reorderable`'s `ReorderableRow` state machine): items are `key`ed on the tab id; a tab dragged along its **own** strip publishes no ghost (`TabTearOffDragSession` clears it while `dropPreview.group === entry.group`) and the strip draws it at the pointer's travel since the grab (`TabWorkspace.dragGrabScreenPx` / `dragPointerScreenPx`), a neighbour slides one tab-width aside (spring `StiffnessMediumLow`) when the carried tab's *edge* crosses its *centre*, and on release the session sets `pendingReorder` instead of reordering — the strip's `TabStripMotion.settle` slides the tab into the target slot, then `reorder()` + `rest()` in the same frame, so nothing jumps. The own-strip drop index is `reorderTarget` (edge-crossing rule, RTL inferred from the slots, same rule as the motion) and `insertionIndex` is direction-aware too (a right-to-left strip used to resolve every drop mirrored). Offsets are draw-time `graphicsLayer` translations, so `tabSlot` geometry is always the settled layout. Tabs open/close by width (`AnimatedVisibility`, 200 ms, `clip = false` so the carried card can leave its slot) and the stock close button delays `workspace.close` by the exit duration; `TabEntry.isEntering` marks a tab the strip has not shown yet. `TabWindows` has two app slots: `windowWrapper` wraps the whole window *including* its strip (per-window locals, background), `windowBodyWrapper` wraps only what is under the strip and is where window-level chrome goes (a `DockLayout`, activity bars) — composed at one call site for every window, so a tab change neither rebuilds it nor moves the body's relocation keys. `SatelliteWorkspace` (docking) and `TabWorkspace` (Chrome-like tabs) are both built on it — put new cross-window gestures there rather than duplicating the geometry or the drag bookkeeping. `DockLayout` (`window/tao/DockLayout.kt` + `DockSplitter.kt` + `DockTransferTarget.kt`) is the dock: sides nest in `sideOrder` (outermost first, default `DefaultDockSideOrder` = top, bottom, left, right — **not** `DockSide.entries`, whose declaration order is left, right, top, bottom), a side is either *split* (panels share its length by `Docked.weight` and its thickness by `dockExtent(side)`) or *layered* (`layeredSides`: each panel a full-length layer of its own `Docked.extent`, the way a nested split-pane tree looks), `splitter` / `panel` slots carry the app's own chrome (`DockSplitterScope.dockSplitterHandle()` is the gesture; an overflowing `requiredWidth` grip on a 1 dp line works), sides are physical and the layout forces LTR internally then restores the caller's direction for content/panels/slots, and every panel and the content are `movableContentOf` so no layout change (extent, weight, order, side, restore, side order, direction) rebuilds a subtree — the layout's inputs live in `DockLayoutState` as snapshot state because the bands are separate composables that strong skipping would otherwise skip. Extents are fitted proportionally when the window is too small (`fit`). Drop feedback lives in `DockZoneHints.kt` and **the rectangles it draws are the target**: it publishes them to `HostGeometry.zoneBoundsInWindowPx`, and `dockTargetAt(draggedScreenRectPx, pointerScreenPx)` → `dockSideEntered` resolves a drop against those, not against the window's edges — on a layered side the strip is inset behind the existing layers, and the window's own edge behind them is nothing. A zone is entered when the dragged **satellite's** edge (its window, or the tear-out ghost) is within one zone thickness of the zone's outer edge and overlaps it across the other axis — edge alignment, not overlap, or a full-height panel could never be torn out; the pointer inside a zone is a second trigger and the tie-break, else the smallest gap wins. The rects come from `DockLayoutState.landingRectPx`: the side's measured band, inside existing layers, counting the dragged panel's own side as already freed; `hintedSides` drops the side the panel is alone on in that window, so it is neither drawn nor droppable. **`dockSides`**: `Satellite(dockSides = …)` (default all four, empty = floating-only) is fixed at declaration and enforced everywhere — `dock()` and `restore()` refuse another side, `hintedSides` and `DockZoneHints` neither draw nor publish it, the drag sessions resolve through `dockTargetFor(entry, …)` and the Wayland target filters on `drag.entry.dockSides`, and the default header hides its Dock action for a floating-only palette. **`floatable = false`** is the opposite knob — a fixed panel: `undock()` refuses it, a `restore()` that floats it is ignored, the docked drag publishes no tear-out ghost and a release off every zone leaves it in place, the default header drops its Float action, and the declaration requires a docked `initialPlacement`. **`reorderable = false`** pins the rank: `dock(order)` is ignored for it (it takes the declared rank back), `insertInStack` pushes any other panel past the last pinned one (`pinnedFloor`), `dropSlotsPx` returns nothing for a pinned dragged panel and keeps the forbidden ranks as **empty** slots so a slot's index is still its rank, `hintedSides` drops its own side, `targetFor` strips the rank off a target, and `satelliteDragHandle` is inert when `canBeDragged` says a drag could not end anywhere. **Telling the two gestures apart** (what an app adapts its UI to, #663 review): `TaoWindow.canPlaceOnScreen` is the public capability (branch on it, not on `isNativeWaylandSurface`), `SatelliteScope.isCompositorPlaced` is the same answer for the window the chrome is composed in (the floating scope reads the satellite's own window through a lambda since the scope outlives it; the docked scope reads `entry.dockHost`), `SatelliteCaptionStripWidth` + the `floatingCaption` slot of `Satellite` are the strip the title bar leaves to the compositor's move — reserved and composed **only** where `isCompositorPlaced`, so an app never has to guess a width or accidentally claim the only area that can move the palette — and `SatelliteWorkspace.dragKind` (`Window` / `Transfer`) says how a drag in flight is carried, which is what tells preview code whether `dragGhost` will ever be published. `reader-dock-demo`: the book tree and the contents are `floatable = false` + `reorderable = false` + `dockSides = setOf(Right)` — furniture, and no pane can be dropped in front of them. **Ranks**: `Docked.order` is kept contiguous from 0 per (host, side) by `dock()` / `undock()` (`dock(order)` inserts at that index, `null` = the rank the entry last held on that side, remembered in `SatelliteEntry.dockMemory`, else the end), and a side with panels publishes `DockDropZone.slots` — one rect per rank, cut at the neighbours' centres, the dragged panel excluded — so `DockTarget.order` is the rank under the pointer (`dockSlotAt`), the own rank (`ownTarget`) being no target; a pointer over a stack beats a strip across its corner. `dropAt` converts a shown-rank into the full rank (closed panels keep theirs).

A strip written from scratch composes `TabHoverPreviewPopup` and needs nothing else — the anchor is the slot `Modifier.tabSlot` already publishes, which also publishes the hovered tab itself (`TabStripScope.hoveredTab`). The card is withheld in every case where it would be in the way, and the rule lives on `hoveredTab` so custom chrome inherits it: the selected tab, whose body is on screen already; a drag in flight, which passes the carried tab over every neighbour without pointing at any; a press, until the pointer has moved on; and the card itself, since reaching it means having left the tab. That last one has to be said explicitly — a popup surface takes the pointer off the window beneath it, so the tab never hears it leave. **The picture.** `TabWorkspace(captureThumbnails = true)` keeps a reduced snapshot of the body each tab last showed, for a card to draw (`TabEntry.thumbnail`, refreshed on demand with `captureThumbnail`). Off by default: it records the body into a layer and reads it back. A native embed draws outside the scene and is missing from the picture, which is documented. **The swallowed click.** The whole tab is a drag grip and it claims the press before the tab's own click gesture, so a click whose pointer drifts past the touch slop became a drag instead — and a drag that ended where it began left the strip exactly as it was, the click lost and the tab having wobbled for nothing. Lifting a tab now selects it, as a browser does on the press, so the click always lands and the tab being carried is always the one on screen. `examples/tabs-demo` shows the file path under the title, `jewel-tabs-demo` draws a card entirely in Jewel's own colours, and `reader-dock-demo` hangs a right-to-left card off the right edge of its seforim. --- .../api/decorated-window-tao.api | 51 +- .../window/tao/TabHoverPreview.kt | 439 ++++++++++++++++++ .../nucleusframework/window/tao/TabStrip.kt | 19 + .../nucleusframework/window/tao/TabWindows.kt | 12 +- .../window/tao/TabWorkspace.kt | 119 ++++- .../window/tao/TabHoverPreviewTest.kt | 196 ++++++++ .../window/tao/TabWorkspaceTest.kt | 40 ++ .../window/tao/TaoSceneTestBattery.kt | 37 ++ .../tao/TaoSceneTestBatteryDriftTest.kt | 1 + .../tao/headful/SatelliteWorkspaceFixture.kt | 16 + .../window/tao/headful/TabWorkspaceFixture.kt | 47 +- .../headful/TabWorkspaceMouseHeadfulCases.kt | 93 +++- .../headful/WorkspaceFileDropHeadfulCases.kt | 5 + .../jeweltabsdemo/DemoState.kt | 11 +- .../jeweltabsdemo/JewelTabStrip.kt | 78 +++- .../nucleusframework/jeweltabsdemo/Main.kt | 2 +- .../nucleusframework/readerdockdemo/Main.kt | 2 +- .../readerdockdemo/ReaderState.kt | 9 +- .../readerdockdemo/ReaderTabStrip.kt | 39 +- .../nucleusframework/tabsdemo/DemoState.kt | 33 +- .../nucleusframework/tabsdemo/DemoTabStrip.kt | 38 +- .../dev/nucleusframework/tabsdemo/Main.kt | 2 +- 22 files changed, 1259 insertions(+), 30 deletions(-) create mode 100644 decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/TabHoverPreview.kt create mode 100644 decorated-window-tao/src/test/kotlin/dev/nucleusframework/window/tao/TabHoverPreviewTest.kt diff --git a/decorated-window-tao/api/decorated-window-tao.api b/decorated-window-tao/api/decorated-window-tao.api index be942b6dc..6c2322dac 100644 --- a/decorated-window-tao/api/decorated-window-tao.api +++ b/decorated-window-tao/api/decorated-window-tao.api @@ -211,10 +211,16 @@ public final class dev/nucleusframework/window/tao/ComposableSingletons$Satellit public final fun getLambda$1877818949$Nucleus_decorated_window_tao ()Lkotlin/jvm/functions/Function3;

A feature that can only be built reflectively is a feature we do not ship: document the gap and offer a working alternative -- **Public API freeze**: root `build.gradle.kts` applies kotlinx binary-compatibility-validator + `explicitApi()` to every non-example module. Baselines live in `/api/.api`. After intentional public API changes run `./gradlew apiDump` and commit the dump; `apiCheck` (wired into `check` / `preMerge`) fails on accidental ABI drift. Exception: `decorated-window-jewel` (JVM 25) is ignored by BCV until ASM supports class-file 69 — still uses `explicitApi()`. Helper: `scripts/fix-explicit-api.py` for mechanical visibility/return-type fixes from kotlinc diagnostics. +- **Public API freeze**: root `build.gradle.kts` applies kotlinx binary-compatibility-validator + `explicitApi()` to every non-example module.

Helper: `scripts/fix-explicit-api.py` for mechanical visibility/return-type fixes from kotlinc diagnostics. **Experimental surface**: the whole satellite / dock family (`Satellite`, `SatelliteWindow`, `SatelliteWorkspace`, `SatellitePlacement`, `DockLayout`, `DockSplitterScope`, …, in both `decorated-window-tao` and `nucleus-application`) is marked `@ExperimentalNucleusApi` (`dev.nucleusframework.window`, lives in `decorated-window-core` so every consumer sees it; opt-in level ERROR). Library modules and the demos opt in module-wide with `compilerOptions { optIn.add("dev.nucleusframework.window.ExperimentalNucleusApi") }`; new public satellite/dock declarations must carry the marker, the tab family is stable and unmarked. - **KDoc on public API**: `UndocumentedPublicClass` / `UndocumentedPublicFunction` are enforced by detekt (`detekt` is wired into `check` / `preMerge`). Pre-existing gaps are grandfathered in per-module `/detekt-baseline.xml` files — any *new* undocumented public class or function fails the build. Do not regenerate a baseline to silence a new finding; write the KDoc. `UndocumentedPublicProperty` stays off because the generated icon/symbol catalogs (`sf-symbols`, `freedesktop-icons`) would swamp it - **Logging**: `java.util.logging` is the single facade for every runtime module — no SLF4J dependency forced on consumers, no raw `println` / `System.err` in `src/main`. Logger names must be the fully-qualified class name (or an explicit `dev.nucleusframework.*` string) so the whole framework sits under one JUL namespace. `allowNucleusRuntimeLogging = true` is an opt-in convenience that raises the `dev.nucleusframework` logger to `nucleusLoggingLevel` and attaches a colored console handler; apps that configure JUL themselves (`logging.properties`, `jul-to-slf4j`) leave it `false` and Nucleus never touches the JUL configuration - `decorated-window-tao` is the only window backend (no AWT, native event-loop-driven, true Windows fullscreen, GraalVM native-image first-class). The AWT-based backends (`decorated-window-awt` / `-jbr` / `-jni`), `NucleusBackend`, `LocalNucleusBackend`, the `backend =` parameter of `nucleusApplication`, and `NucleusWindowUnsafe.awtWindow` / `awtDialog` were all removed in 2.6.

Library modules and the demos opt in module-wide with `compilerOptions { optIn.add("dev.nucleusframework.window.ExperimentalNucleusApi") }`; new public satellite/dock/tab declarations must carry the marker. - **KDoc on public API**: `UndocumentedPublicClass` / `UndocumentedPublicFunction` are enforced by detekt (`detekt` is wired into `check` / `preMerge`). Pre-existing gaps are grandfathered in per-module `/detekt-baseline.xml` files — any *new* undocumented public class or function fails the build. Do not regenerate a baseline to silence a new finding; write the KDoc. `UndocumentedPublicProperty` stays off because the generated icon/symbol catalogs (`sf-symbols`, `freedesktop-icons`) would swamp it - **Logging**: `java.util.logging` is the single facade for every runtime module — no SLF4J dependency forced on consumers, no raw `println` / `System.err` in `src/main`. Logger names must be the fully-qualified class name (or an explicit `dev.nucleusframework.*` string) so the whole framework sits under one JUL namespace. `allowNucleusRuntimeLogging = true` is an opt-in convenience that raises the `dev.nucleusframework` logger to `nucleusLoggingLevel` and attaches a colored console handler; apps that configure JUL themselves (`logging.properties`, `jul-to-slf4j`) leave it `false` and Nucleus never touches the JUL configuration - `decorated-window-tao` is the only window backend (no AWT, native event-loop-driven, true Windows fullscreen, GraalVM native-image first-class). The AWT-based backends (`decorated-window-awt` / `-jbr` / `-jni`), `NucleusBackend`, `LocalNucleusBackend`, the `backend =` parameter of `nucleusApplication`, and `NucleusWindowUnsafe.awtWindow` / `awtDialog` were all removed in 2.6.

Copy with `cp -R` instead, as the GraalVM path already did. - Warn when an extension is embedded into an app whose entitlements still grant `allow-unsigned-executable-memory` / `disable-library-validation` (both in the default entitlements); the host app has been reported not to launch with them. The demo's own entitlements now carry `allow-jit` only. - Document that `run` cannot exercise the extension (`runDistributable` can) and that runtime activation needs an Apple-issued profile. - Port the demo to the 2.6 `nucleusApplication` / `DecoratedWindow` entry point and list it in CLAUDE.md.

Always provide a Kotlin fallback when native lib is unavailable. Native code that must drop a pending JNI exception (a Kotlin callback that threw) calls `nucleus_jni_clear_exception(env)` from `native-common/nucleus_jni.h` — never a bare `ExceptionClear`. 5. **GraalVM reachability metadata** — create `/src/main/resources/META-INF/native-image/dev.nucleusframework/nucleus./reachability-metadata.json` declaring all JNI-accessible classes/methods. Without this, native-image silently eliminates the bridge. 6. **CI build** (`build-natives.yaml`) — add one build step per platform job, gated with `if: steps.natives-cache.outputs.cache-hit != 'true'`, plus the library entries in that platform's `Verify ... natives` FILES list. Native outputs are cached keyed on `hashFiles('**/src/main/native/**', ...)`, so the new sources invalidate the cache automatically. Each platform job publishes a single merged artifact (`natives-windows`, `natives-macos`, `natives-linux-{x64,aarch64}`); consumer workflows fetch them all with one `pattern: 'natives-*'` download step and need **no changes** for a new module. 7. **CI verify lists** — add the 6 arch paths to the EXPECTED arrays of the "Verify all natives present" steps in `pre-merge.yaml` and `publish-maven.yaml`. -Common pitfalls: forgetting Linux `.so` in verify lists, missing `reachability-metadata.json`, forgetting the `cache-hit` guard on new build steps in `build-natives.yaml`. +Common pitfalls: forgetting Linux `.so` in verify lists, missing `reachability-metadata.json`, forgetting the `cache-hit` guard on new build steps in `build-natives.yaml`, swallowing JNI exceptions with a silent `ExceptionClear`.

Measured on the title-bar double-click zoom, only 2 of 20 steps had their content presented before the next step arrived. - TaoComposeSceneHost.onResized presents a frame at the new size inside the resize dispatch, for every resize (what prepareFullscreenFrame already did for #327), without pumping the dispatcher there. The next render-loop frame records and paces but skips its redundant replay, or the following same-turn present waits ~15 ms in nextDrawable; the loop's vsync park moves off the render thread for the same reason. - Vendored tao steps the maximize/restore zoom itself instead of the NSWindow animator: 16 ms steps eased over animationResizeTime:, a new request cancels the chain in flight (zoom_generation), standard_frame is guarded while animating, and is_zoomed() reports the tracked target mid-animation. Overlapping animator animations were non-deterministic once presents became synchronous (window v2 clone stress case). - nativeResize anchors the stale drawable top-left instead of stretching, for a present that fails. - Headful: the #576 case gains a present-lag gate (TaoPresentDiagnostics) and a new maximize/restore zoom case; both macOS-only for now. --- .../window/tao/scene/TaoComposeSceneHost.kt | 117 ++++++++++++------ .../window/tao/scene/TaoPresentDiagnostics.kt | 29 +++++ .../src/main/native/macos/NucleusTaoMetal.m | 51 ++++---- .../tao/src/platform_impl/macos/util/async.rs | 115 ++++++++++++----- .../tao/src/platform_impl/macos/window.rs | 19 +++ .../headful/AnimatedWindowSizeHeadfulCases.kt | 89 ++++++++++++- 6 files changed, 332 insertions(+), 88 deletions(-) create mode 100644 decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/scene/TaoPresentDiagnostics.kt diff --git a/decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/scene/TaoComposeSceneHost.kt b/decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/scene/TaoComposeSceneHost.kt index 751454ea4..6ea7ee498 100644 --- a/decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/scene/TaoComposeSceneHost.kt +++ b/decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/scene/TaoComposeSceneHost.kt @@ -56,6 +56,7 @@ import dev.nucleusframework.window.tao.render.LocalTaoTextSelectionA11yPublisher import dev.nucleusframework.window.tao.render.TaoSelectionAccessibilityObserver import dev.nucleusframework.window.tao.shouldApplyLargeCornerRadius import kotlinx.coroutines.CoroutineDispatcher +import kotlinx.coroutines.Dispatchers import kotlinx.coroutines.asCoroutineDispatcher import kotlinx.coroutines.awaitCancellation import kotlinx.coroutines.coroutineScope @@ -718,12 +719,38 @@ internal class TaoComposeSceneHost( NativeMetalBridge.nativeResize(attachmentHandle, widthPx, heightPx, scale) scene?.size = IntSize(widthPx, heightPx) updateWindowInfoSize() - window.requestRedraw() + // Present a frame at the new size in this very run-loop turn (#576). + // AppKit has already applied the bounds; had the present waited for + // the display-link tick, Core Animation would show the new bounds + // with the *previous* drawable stretched over them + // (`kCAGravityResize`) — one stale frame per step of a + // `WindowState.size` animation or of the maximize/restore zoom, read + // as the whole content trembling and trailing the window edge. + // Same-turn presenting is what [prepareFullscreenFrame] already does + // for #327.

The modal resize/move loop keeps its current behaviour. - `setVSyncEnabled` tracks the interval the host asked for. - Every Windows present is recorded in TaoPresentDiagnostics; the #576 headful cases gate Windows too (the instant maximize yields one step). Measured on the animated-height case: same-turn present 7 ms -> 1.3 ms, step cadence uniform at the display rate instead of alternating. --- .../tao/scene/TaoComposeSceneHostWindows.kt | 145 ++++++++++++++---- .../window/tao/scene/TaoPresentDiagnostics.kt | 10 +- .../headful/AnimatedWindowSizeHeadfulCases.kt | 22 ++- 3 files changed, 135 insertions(+), 42 deletions(-) diff --git a/decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/scene/TaoComposeSceneHostWindows.kt b/decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/scene/TaoComposeSceneHostWindows.kt index cb334ac6d..7d2025492 100644 --- a/decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/scene/TaoComposeSceneHostWindows.kt +++ b/decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/scene/TaoComposeSceneHostWindows.kt @@ -843,7 +843,7 @@ internal class TaoComposeSceneHostWindows( // replaces the queued frame rather than lining up behind it, so // what the user sees during the drag stays current. val pacedByVSync = attachmentHandle != 0L - if (pacedByVSync) NativeTaoGlBridge.nativeSetVSyncEnabled(attachmentHandle, false) + if (pacedByVSync) setVSyncEnabled(false) try { dev.nucleusframework.window.tao.ffi.NativeTaoWindowsDndBridge.nativeStartDrag( hwnd = hwnd, @@ -853,7 +853,7 @@ internal class TaoComposeSceneHostWindows( pump = OutboundDragPump(), ) } finally { - if (pacedByVSync) NativeTaoGlBridge.nativeSetVSyncEnabled(attachmentHandle, true) + if (pacedByVSync) setVSyncEnabled(true) // Unwedge rendering: an invalidation raised during the drag // latched `redrawPending` while DoDragDrop's pump ate the // matching REDRAW_REQUESTED, which suppresses every later @@ -1068,7 +1068,7 @@ internal class TaoComposeSceneHostWindows( onResized(widthPxNew, heightPxNew) return } - NativeTaoGlBridge.nativeSetVSyncEnabled(attachmentHandle, false) + setVSyncEnabled(false) try { if (widthPxNew != widthPx || heightPxNew != heightPx) { // Resize the child + immediately present a themed clear: @@ -1085,10 +1085,24 @@ internal class TaoComposeSceneHostWindows( } onResized(widthPxNew, heightPxNew) } finally { - NativeTaoGlBridge.nativeSetVSyncEnabled(attachmentHandle, true) + setVSyncEnabled(true) } } + /** + * Swap interval as this host last set it — `true` = 1 (pace on the + * display refresh), `false` = 0 (present immediately, replacing a queued + * frame).

Date: Thu, 17 Sep 2026 20:46:47 +0300 Subject: [PATCH 133/233] fix(tao): stop wake-served redraws from starving mouse input on Windows MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Since 89c8cdea (#659) the Windows `UserEvent::Wake` handler drains the main dispatcher and serves the pending redraws itself, so an embed's native modal loop keeps the window painting. But a wake is a posted message and Win32 hands posted messages out before hardware input: a frame served from the wake resumes the continuations that post the next wake, an animating window (a `withFrameNanos` producer, an infinite transition) keeps the posted queue non-empty forever, and every WM_MOUSEMOVE / WM_LBUTTONDOWN starves behind it. The window paints at full rate and takes no clicks — seen on tao-demo's Texture and Demo tabs. The wake now serves frames only when `GetQueueStatus(QS_INPUT)` reports no input in the queue; otherwise the requests stay pending and the `MainEventsCleared` tick that follows the input serves them, as before #659. Paint-derived ticks rank below input, so that path never starved. Bisected on Windows with synthetic clicks against the JNI event entry: every commit up to 80d05639 delivers 3/3 clicks, 89c8cdea and after 0–1/3; with this change 3/3 again. Headful `native view` (robot right-click context menu, monkeys), `#576` and `tab mouse click` cases stay green. --- .../src/main/native/src/event_loop.rs | 29 ++++++++++++++++++- 1 file changed, 28 insertions(+), 1 deletion(-) diff --git a/decorated-window-tao/src/main/native/src/event_loop.rs b/decorated-window-tao/src/main/native/src/event_loop.rs index 0800b413c..166ba117e 100644 --- a/decorated-window-tao/src/main/native/src/event_loop.rs +++ b/decorated-window-tao/src/main/native/src/event_loop.rs @@ -153,6 +153,17 @@ fn x11_display() -> Option { /// call site so a frame sees the work that produced it.

`TaoWindow.isMinimizable` / `setMinimizable()`: snapshot-backed like `isResizable`, applied post-creation through the same `LaunchedEffect` re-apply as `resizable` (no builder flag). - Both chromes drop the slot: `resolveWindowControl` (Windows caption buttons and the standalone `WindowControls`) and `WindowControlsLinux`. - Native: `UserEvent::SetMinimizable` -> tao `set_minimizable`. macOS clears `NSWindowStyleMaskMiniaturizable` (the yellow traffic-light greys out, Cmd+M and the Window menu follow); Windows drops `WS_MINIMIZEBOX` (taskbar click, Win+Down, system menu). tao's Linux implementation is a no-op, so there only the title-bar button disappears; documented on `setMinimizable`. - `DecoratedDialog` passes `minimizable = false`: its chrome was already close-only on Windows / Linux (`DialogTitleBar`), the macOS traffic-lights now match. `NucleusWindowHost.Window` is a public `fun interface`, so this is a deliberate ABI change for themed hosts; `apiDump` regenerated for `decorated-window-tao` and `nucleus-application`. --- .../api/decorated-window-tao.api | 6 ++-- .../dev/nucleusframework/window/TitleBar.kt | 1 + .../nucleusframework/window/WindowControls.kt | 12 ++++++-- .../window/tao/DecoratedDialog.kt | 3 ++ .../window/tao/DecoratedWindowComposable.kt | 8 ++++++ .../window/tao/DecoratedWindowNucleusV2.kt | 2 ++ .../nucleusframework/window/tao/TaoWindow.kt | 28 +++++++++++++++++++ .../window/tao/deco/WindowControlsLinux.kt | 2 ++ .../window/tao/ffi/NativeTaoBridge.kt | 6 ++++ .../src/main/native/src/event_loop.rs | 9 ++++++ .../src/main/native/src/events.rs | 4 +++ .../src/main/native/src/window_jni.rs | 13 +++++++++ .../window/ChromeLogicTest.kt | 14 ++++++++++ .../api/nucleus-application.api | 22 +++++++-------- .../application/DecoratedWindow.kt | 8 ++++++ .../application/NucleusWindowHost.kt | 11 ++++++++ .../internal/TaoDecoratedWindowAdapter.kt | 4 +++ .../application/NucleusWindowHostTest.kt | 7 +++++ 18 files changed, 144 insertions(+), 16 deletions(-) diff --git a/decorated-window-tao/api/decorated-window-tao.api b/decorated-window-tao/api/decorated-window-tao.api index 2e448288b..6012c4f9d 100644 --- a/decorated-window-tao/api/decorated-window-tao.api +++ b/decorated-window-tao/api/decorated-window-tao.api @@ -251,7 +251,7 @@ public final class dev/nucleusframework/window/tao/DecoratedDialogKt { } public final class dev/nucleusframework/window/tao/DecoratedWindowComposableKt { -

Events are routed back to registrations by root in lib.rs; a root already watched is not re-watched unless a recursive registration arrives over a non-recursive one, and the backend is dropped when the last registration goes. A per-watcher mutation lock serialises watch/unwatch/close and is never taken by callbacks. On macOS, FSEvents attaches an inode's accumulated flags to every event, so a rename of a long-existing file reaches the debouncer as Create+Rename+Modify on the gone path and gets folded into a bare Created(new); a delete of a pre-existing file surfaced as Modified. An FsEventsNormalizer now fronts the debounced backend (Create/Modify of an absent path, Remove of a present path and Create of an already-tracked path are history and dropped), the canonical root is handed to the backend so file-id pairing matches FSEvents' spelling, and renames the backend cannot pair are reported as Removed(old)+Created(new) instead of being discarded. Raw delivery is left untouched. Real-filesystem tests cover the four rename shapes, a non-canonical root, the pre-existing delete, the Raw rename contract, and 24 registrations sharing one native watcher (inotify instances via /proc on Linux, OS threads via ps on macOS), with per-registration routing and unwatch of a single path checked through the shared backend.

fix(fs-watcher): hand the canonical root to inotify as well MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit With one INotifyWatcher per FsWatcher, two spellings of the same directory (its real path and a symlink to it) share a single inotify watch descriptor, and notify keeps one path per descriptor — so the alias that registered last decided the spelling every event was reported under and the other registration matched nothing. Unwatching either alias would also have removed the descriptor from under the other. The backend is now handed the canonical root on Linux as on macOS: one watch per real directory, shared by every alias, with the Kotlin side projecting events back onto each registration's own spelling exactly as it already does for FSEvents. Windows keeps the registered spelling because canonicalize() yields \\?\ verbatim paths that Java's toRealPath() never produces. A symlink root registered with followSymlinks = false is thereby reported on Linux the way the option documents and macOS always did (its target's events are not remapped onto the link), so that real-fs test now runs on Linux too. --- CLAUDE.md | 2 +- fs-watcher/src/main/native/src/lib.rs | 24 +++++++++++++------ .../fswatcher/FsWatcherRealFileSystemTest.kt | 6 ++--- 3 files changed, 21 insertions(+), 11 deletions(-) diff --git a/CLAUDE.md b/CLAUDE.md index fbd24dbd5..253894745 100644 --- a/CLAUDE.md +++ b/CLAUDE.md @@ -30,7 +30,7 @@ Published releases are `2.5.x` (latest tag `v2.5.0`).

Two levers, tried in order, each falling through to the next when the directory cannot be created or written to: 1. `-Dnucleus.native.cacheDir=`, which also works for libraries loaded before any application code runs and bakes into the launcher `.cfg` through the existing `jvmArgs`; 2. `NativeLibraryLoader.cacheDirectory`, for a path computed in `main()`; 3. the platform default. The root is resolved once, at the first extraction, so every library of a run shares it; a later assignment is ignored with a warning. The content-addressed layout of #304 is kept under the chosen root. Also fixes a pre-existing defect in the default: a set-but-empty or relative `XDG_CACHE_HOME` / `LOCALAPPDATA` made the root relative, putting native libraries under the process working directory. --- .../gradle/NativeModulePlugin.kt | 35 ++-- core-runtime/api/core-runtime.api | 3 + .../core/runtime/NativeLibraryLoader.kt | 183 +++++++++++++++--- .../core/runtime/NativeLibraryLoaderTest.kt | 162 +++++++++++++++- 4 files changed, 345 insertions(+), 38 deletions(-) diff --git a/buildSrc/src/main/kotlin/dev/nucleusframework/gradle/NativeModulePlugin.kt b/buildSrc/src/main/kotlin/dev/nucleusframework/gradle/NativeModulePlugin.kt index 896903aa0..ee01bfa86 100644 --- a/buildSrc/src/main/kotlin/dev/nucleusframework/gradle/NativeModulePlugin.kt +++ b/buildSrc/src/main/kotlin/dev/nucleusframework/gradle/NativeModulePlugin.kt @@ -142,25 +142,34 @@ open class NativeModuleExtension( return task } - /** Mirrors `NativeLibraryLoader.resolveCacheDir()` in `core-runtime`. */ + /** + * Mirrors `NativeLibraryLoader.defaultCacheDir()` in `core-runtime`. + * + * Deliberately only the platform default: an application that relocates its + * cache (`NativeLibraryLoader.CACHE_DIR_PROPERTY` / `cacheDirectory`) does so + * in its own JVM, which this build never sees, so guessing an override here + * would evict a directory nothing reads and leave the real one untouched. + * Developers running with a relocated cache clear it themselves. + */ private fun loaderCacheDir(): File { val os = System.getProperty("os.name", "").lowercase() val userHome = System.getProperty("user.home") + + // Blank or relative values are ignored, exactly as the loader does: + // evicting a relative directory would miss the cache actually in use. + fun envDir(name: String): File? = + project.providers + .environmentVariable(name) + .orNull + ?.takeIf { it.isNotBlank() } + ?.let(::File) + ?.takeIf { it.isAbsolute } + val base = when { - os.contains("win") -> - project.providers - .environmentVariable("LOCALAPPDATA") - .orNull - ?.let(::File) - ?: File(userHome, "AppData/Local") + os.contains("win") -> envDir("LOCALAPPDATA") ?: File(userHome, "AppData/Local") os.contains("mac") -> File(userHome, "Library/Caches") - else -> - project.providers - .environmentVariable("XDG_CACHE_HOME") - .orNull - ?.let(::File) - ?: File(userHome, ".cache") + else -> envDir("XDG_CACHE_HOME") ?: File(userHome, ".cache") } return File(base, "nucleus/native") } diff --git a/core-runtime/api/core-runtime.api b/core-runtime/api/core-runtime.api index f173f5440..3e1b655f5 100644 --- a/core-runtime/api/core-runtime.api +++ b/core-runtime/api/core-runtime.api @@ -99,9 +99,12 @@ public final class dev/nucleusframework/core/runtime/LinuxUiToolkit$Companion { } public final class dev/nucleusframework/core/runtime/NativeLibraryLoader { + public static final field CACHE_DIR_PROPERTY Ljava/lang/String; public static final field INSTANCE Ldev/nucleusframework/core/runtime/NativeLibraryLoader; + public final fun getCacheDirectory ()Ljava/nio/file/Path; public final fun load (Ljava/lang/String;Ljava/lang/Class;Ljava/lang/String;Ljava/util/List;)Z public static synthetic fun load$default (Ldev/nucleusframework/core/runtime/NativeLibraryLoader;Ljava/lang/String;Ljava/lang/Class;Ljava/lang/String;Ljava/util/List;ILjava/lang/Object;)Z + public final fun setCacheDirectory (Ljava/nio/file/Path;)V } public final class dev/nucleusframework/core/runtime/NucleusApp { diff --git a/core-runtime/src/main/kotlin/dev/nucleusframework/core/runtime/NativeLibraryLoader.kt b/core-runtime/src/main/kotlin/dev/nucleusframework/core/runtime/NativeLibraryLoader.kt index 3dac9ad4d..bf4771934 100644 --- a/core-runtime/src/main/kotlin/dev/nucleusframework/core/runtime/NativeLibraryLoader.kt +++ b/core-runtime/src/main/kotlin/dev/nucleusframework/core/runtime/NativeLibraryLoader.kt @@ -12,8 +12,32 @@ import java.util.logging.Logger * Centralized native library loader with persistent caching. * * Extracts native libraries from JAR resources into a stable cache directory - * (`~/.cache/nucleus/native/` on macOS/Linux, `%LOCALAPPDATA%/nucleus/native/` on Windows) - * so that subsequent launches skip the extraction I/O entirely. + * so that subsequent launches skip the extraction I/O entirely.

thread, not the AWT EDT MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Notification, launcher and media-control callbacks were posted with SwingUtilities.invokeLater. Under the Tao backend the AWT EDT is not Compose's UI thread, so those callbacks land on a thread that paints nothing — the same mistake menu-macos fixed in #310, still present in five modules. WindowBackend documents itself as the escape hatch for exactly this ("avoid touching the AWT event dispatch thread when running on Tao") and was read nowhere: its only use in the tree was the write in nucleusApplication. - add NucleusUiThread to core-runtime: a single marshalling point backed by an executor the backend registers, falling back to EventQueue.invokeLater when no Nucleus entry point ran.

Whether a PKG is a store package is now a DSL choice, macOS { pkg { appStore } }, defaulting to the previous behaviour. With appStore = false the PKG takes the same non-sandboxed pipeline as the DMG, electron-builder signs the installer itself from the bare NAME (TEAMID) identity, a DSL keychain travels as CSC_KEYCHAIN, and notarizePkg notarizes the .pkg. electron-builder silently emits an unsigned package when no matching "Developer ID Installer" certificate is found, so the task verifies the result with pkgutil --check-signature. pkg { preInstall / postInstall } stage install scripts for pkgbuild --scripts. The App Store rejects them (error 90254), so they require appStore = false, checked at configuration time. The staged preinstall/postinstall are shims. electron-builder sets BundlePre/PostInstallScriptPath *and* passes --scripts, so PackageInfo declares each script twice and the Installer runs it twice, confirmed on a real install. The shim skips the per-bundle pass and execs the app's script, staged under a name electron-builder's scan does not match. Runtime: ExecutableRuntime.isSandboxed() reads APP_SANDBOX_CONTAINER_ID. The scheduler gates on it instead of isPkg(), and a Developer ID PKG becomes self-updatable while the sandboxed store build stays excluded. --- CLAUDE.md | 1 + core-runtime/api/core-runtime.api | 1 + .../core/runtime/ExecutableRuntime.kt | 21 +++ .../runtime/ExecutableRuntimeSandboxTest.kt | 41 +++++ .../dsl/JvmApplicationDistributions.kt | 17 +- .../desktop/application/dsl/PkgSettings.kt | 66 ++++++++ .../application/dsl/PlatformSettings.kt | 34 +++- .../application/dsl/SandboxingSettings.kt | 10 +- .../desktop/application/dsl/TargetFormat.kt | 20 ++- .../application/internal/MacPkgScripts.kt | 124 +++++++++++++++ .../internal/configureGraalvmApplication.kt | 27 +++- .../internal/configureJvmApplication.kt | 42 +++-- .../ElectronBuilderConfigGenerator.kt | 39 +++-- .../ValidatedMacOSSigningSettings.kt | 29 ++-- .../AbstractElectronBuilderPackageTask.kt | 146 ++++++++++++++---- .../JvmApplicationDistributionsSandboxTest.kt | 55 +++++++ .../dsl/TargetFormatStoreFormatTest.kt | 20 --- .../application/internal/MacPkgScriptsTest.kt | 119 ++++++++++++++ .../internal/PkgScriptValidationTest.kt | 48 ++++++ .../ElectronBuilderPkgConfigTest.kt | 66 ++++++-- .../scheduler/DesktopTaskScheduler.kt | 4 +- .../updater/NucleusUpdater.kt | 6 +- .../updater/CheckForUpdatesLogicTest.kt | 5 +- .../updater/PkgUpdateSupportTest.kt | 36 +++++ 24 files changed, 857 insertions(+), 120 deletions(-) create mode 100644 core-runtime/src/test/kotlin/dev/nucleusframework/core/runtime/ExecutableRuntimeSandboxTest.kt create mode 100644 plugin-build/plugin/src/main/kotlin/dev/nucleusframework/desktop/application/dsl/PkgSettings.kt create mode 100644 plugin-build/plugin/src/main/kotlin/dev/nucleusframework/desktop/application/internal/MacPkgScripts.kt create mode 100644 plugin-build/plugin/src/test/kotlin/dev/nucleusframework/desktop/application/dsl/JvmApplicationDistributionsSandboxTest.kt delete mode 100644 plugin-build/plugin/src/test/kotlin/dev/nucleusframework/desktop/application/dsl/TargetFormatStoreFormatTest.kt create mode 100644 plugin-build/plugin/src/test/kotlin/dev/nucleusframework/desktop/application/internal/MacPkgScriptsTest.kt create mode 100644 plugin-build/plugin/src/test/kotlin/dev/nucleusframework/desktop/application/internal/PkgScriptValidationTest.kt create mode 100644 updater-runtime/src/test/kotlin/dev/nucleusframework/updater/PkgUpdateSupportTest.kt diff --git a/CLAUDE.md b/CLAUDE.md index ce35218ee..ee64dd91b 100644 --- a/CLAUDE.md +++ b/CLAUDE.md @@ -77,6 +77,7 @@ Published releases are `2.5.x` (latest tag `v2.5.0`).

a34eb67c5b4df96fac7e8c0233244fcecdea67e7 Mon Sep 17 00:00:00 2001 From: Elie Gambache Date: Fri, 18 Sep 2026 12:23:34 +0300 Subject: [PATCH 147/233] fix(tao/linux): paint at the drawable's real size, not a predicted one (#444) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit On Wayland `wl_egl_window_resize` only records a *pending* size: the buffer behind the default framebuffer is reallocated inside the next `eglSwapBuffers`. Skia's render target wraps that framebuffer (`fbId = 0`), so building it from the size we just requested overstates it for one frame, and under `SurfaceOrigin.BOTTOM_LEFT` the frame lands that many rows off the top of the real drawable — the band of clear colour the issue sees flicker on roughly a third of the frames of a drag. Both earlier attempts predicted that size rather than reading it: first "the buffer follows the request" (the flash), then "the buffer is one present behind", which had to be confined to KWin because the prediction was wrong elsewhere — it fixed Fedora Mutter and regressed Ubuntu GNOME. `eglQuerySurface` is neither prediction but the answer, so there is no desktop environment left in the decision: `useDrawableSizedPaint`, `drawableWidthPx` / `drawableHeightPx` and `onDrawablePresented` are gone. Where a driver answered with the requested size instead of the real one, this would behave exactly as the code did before it. Layout and the render target are also separated, which is what made the earlier attempt a trade-off in the first place: the scene keeps the window's size, so Compose never measures for a buffer that is a step behind, and only the render target follows the drawable. A frame drawn while the buffer lags is then anchored correctly and merely leaves that step uncovered until the catch-up frame, instead of displacing everything by it. Measured by a new headful case against a nested compositor: 16 of 64 frames painted at a size the buffer did not have before, 0 after, the window converging to its final size. The case fails when it measured nothing — it requires the window to have actually changed size, and reports the render passes dropped on a swap still in flight, because a window the compositor treats as occluded never gets its frame callbacks, renders nothing at all, and used to look exactly like a pass. `taoHeadfulTest` now forwards WAYLAND_DISPLAY so the suite can be pointed at a nested compositor instead of whichever session owns the screen. Defects (1) and (3) of the issue are untouched: the buffer still does not arrive in the same commit as the window geometry, which is a commit-ordering problem between GTK's toplevel and our sub-surface rather than a render target one. --- decorated-window-tao/build.gradle.kts | 9 + .../window/tao/ffi/NativeTaoEglBridge.kt | 18 ++ .../tao/scene/TaoComposeSceneHostLinux.kt | 184 +++++++++--------- .../tao/scene/TaoWaylandFrameDiagnostics.kt | 116 +++++++++++ .../src/main/native/linux/nucleus_tao_egl.c | 52 +++++ .../tao/headful/Issue444HeadfulCases.kt | 162 +++++++++++++++ .../tao/headful/TaoHeadfulTestSuiteMain.kt | 1 + 7 files changed, 455 insertions(+), 87 deletions(-) create mode 100644 decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/scene/TaoWaylandFrameDiagnostics.kt create mode 100644 decorated-window-tao/src/test/kotlin/dev/nucleusframework/window/tao/headful/Issue444HeadfulCases.kt diff --git a/decorated-window-tao/build.gradle.kts b/decorated-window-tao/build.gradle.kts index 22285255f..6b2def11d 100644 --- a/decorated-window-tao/build.gradle.kts +++ b/decorated-window-tao/build.gradle.kts @@ -196,6 +196,15 @@ val taoHeadfulTest by tasks.registering(JavaExec::class) { providers.environmentVariable("NUCLEUS_TAO_LINUX_RENDERER").orNull?.let { environment("NUCLEUS_TAO_LINUX_RENDERER", it) } + // Lets the suite run against a nested compositor + // (`mutter --headless --virtual-monitor …`, `kwin_wayland`) instead of the + // session that happens to own the screen.

TaoView answered a process-global caret rect that nothing ever invalidated, so once a focused text field was destroyed the badge kept appearing over the spot the field used to occupy. Before any field had been focused it was worse: the overrides were only installed when the first text-input session started, so tao's own implementation answered — the content-rect corner with a *top-down* y handed back as a Cocoa bottom-up coordinate — which parks the badge in the bottom-left corner of the screen of an app that has never shown a text field. Three changes, all measured against a logging `NSTextInputClient` probe driven by `TISSelectInputSource` with the badge window tracked through `CGWindowListCopyWindowInfo`: The cached rect is now scoped to the view that pushed it, and every other answer is `NSZeroRect`. That exact shape is the one AppKit reads as "no insertion point": a zero *size* alone does not suppress the badge — `(0, 30, 0x0)`, which is what tao answers, still draws it — and `selectedRange = NSNotFound` plus `invalidateCharacterCoordinates` change nothing at all. A rect falling outside the key window is not drawn either, which is why the corner case only shows on a window large enough to contain it. The overrides are installed per window creation rather than on the first session, so the answer is ours from the first frame. `TaoView` only exists once a window has been built, and the swizzle is idempotent. The input context is deactivated when the session ends. On its own that is not enough — `interpretKeyEvents:` re-activates it on the next keystroke — but it takes the badge down immediately for an app that is not being typed into. The teardown carries the activation token it was handed, because focus moving between fields starts the incoming session *before* the outgoing one is torn down: without the guard, focusing a second field deactivates the context the first teardown then finds live. Same ordering trap as the document cache. --- .../window/tao/ffi/NativeTaoBridge.kt | 37 +++++++++- .../window/tao/scene/TaoComposeSceneHost.kt | 6 +- .../main/native/macos/main_thread_dispatch.m | 65 +++++++++++++++-- .../native/macos/text_input_client_probe.m | 18 +++++ .../src/main/native/src/event_loop.rs | 9 +++ .../src/main/native/src/platform/macos/ffi.rs | 16 ++++- .../src/main/native/src/platform/macos/ime.rs | 70 +++++++++++++++---- 7 files changed, 200 insertions(+), 21 deletions(-) diff --git a/decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/ffi/NativeTaoBridge.kt b/decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/ffi/NativeTaoBridge.kt index f985d0aef..67aab47b7 100644 --- a/decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/ffi/NativeTaoBridge.kt +++ b/decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/ffi/NativeTaoBridge.kt @@ -404,6 +404,19 @@ internal object NativeTaoBridge { rangesOut: LongArray, ): String + /** + * macOS only, headful e2e: the rect TaoView answers + * `firstRectForCharacterRange:` with, filled into [rectOut] (length ≥ 4) + * as `[x, y, width, height]` in Cocoa screen coordinates.

Measured on 26.5 with the pointer parked over a tab strip: enter → exit → enter → exit, all at one screen point. Two sources found — a hover card's own popup panel rising over the pointer, which is a *child window* of ours whose draw margin overlaps the tab it hangs off, and the rebuilds of tao's legacy tracking rect. That reaches Compose as `PointerEventType.Exit` and is taken at face value, so hover state is dropped. Nothing corrects it: `CursorEntered` carries no position and was never forwarded, and a pointer that *rests* sends nothing more. Hover effects and tab hover cards stay dead until the user moves the mouse — the symptom the standing HACK comment in `TaoComposeSceneHost` describes as "hover doesn't render until the user clicks once". A hover card is worse than dead: it dies on its own phantom exit, reopens, and exits again, a loop no pointer can break. So trust the geometry over the event. An exit is ignored when the cursor is demonstrably still ours — inside the view's bounds, and the window on top at that screen point is this window or one of its `childWindows` — and the position is re-published instead; `CursorLeft` is kept for a cursor that really is somewhere else. `mouseEntered:` publishes its position for the same reason. --- .../tao/src/platform_impl/macos/view.rs | 71 ++++++++++++++++++- 1 file changed, 69 insertions(+), 2 deletions(-) diff --git a/decorated-window-tao/src/main/native/vendor/tao/src/platform_impl/macos/view.rs b/decorated-window-tao/src/main/native/vendor/tao/src/platform_impl/macos/view.rs index b3b19bd3b..6ead6d4f4 100644 --- a/decorated-window-tao/src/main/native/vendor/tao/src/platform_impl/macos/view.rs +++ b/decorated-window-tao/src/main/native/vendor/tao/src/platform_impl/macos/view.rs @@ -1218,7 +1218,7 @@ extern "C" fn other_mouse_dragged(this: &NSView, _sel: Sel, event: &NSEvent) { mouse_motion(this, event); } -extern "C" fn mouse_entered(this: &Object, _sel: Sel, _event: id) { +extern "C" fn mouse_entered(this: &NSView, _sel: Sel, event: &NSEvent) { trace!("Triggered `mouseEntered`"); unsafe { let state_ptr: *mut c_void = *this.get_ivar("taoState"); @@ -1233,12 +1233,79 @@ extern "C" fn mouse_entered(this: &Object, _sel: Sel, _event: id) { AppState::queue_event(EventWrapper::StaticEvent(enter_event)); } + // PATCH(nucleus): publish *where* the cursor entered, which AppKit hands us + // in the event and tao drops. `CursorEntered` carries no position, so a + // consumer that tracks the pointer (Compose's hover) only learns it on the + // next `mouseMoved:` — and a pointer that *rests* after entering sends none. + mouse_motion(this, event); trace!("Completed `mouseEntered`"); } -extern "C" fn mouse_exited(this: &Object, _sel: Sel, _event: id) { +/// Is the cursor still over this view, whatever AppKit just claimed? +/// +/// Inside the view's own bounds, and the window on top at that screen point is +/// this one — or one of its **child** windows, which is how Nucleus hosts a +/// native popup layer.

Tao's GTK `draw` and `configure-event` handlers only post to its event channel: `RedrawRequested` / `Resized` reach the host after GDK's after-paint has already committed the toplevel with the new `set_window_geometry`. The frame for configure N could never ride commit N. The widget helper now connects a real `draw` handler on the GtkWindow (`nativeConnectToplevelDraw`); during a resize burst the host renders from it, taking the size from `gtk_window_get_size` (GTK's own configure-event lags the same way), with the content sub-surface in `set_sync` and the swap at interval 0, and waits for the swap before returning — so the buffer is cached compositor-side when GTK's commit applies it, atomically with the geometry. Sync is armed only from an idle swap thread and only with the interval-0 burst, or a commit with a frame callback attached would wait for the very GTK commit the draw has yet to return to. The swap interval is now applied by the swap thread before its present, so it is in force before the first synced commit. 2. Mesa's `wl_egl_window` resize callback adopts the new size only while no back buffer is acquired, and `eglMakeCurrent` acquires one: a resize pushed after it lands in the next frame's buffer, and this frame paints the previous size. `applyPendingNativeResize` now runs before `nativeMakeCurrent`; the Skia surface rebuild a scale change asks for is deferred to when the context is current. Measured with a compositor-driven left-edge resize (KWin scripting, 30 steps of 8 px) and screen capture, counting frames where the content's right edge moves — which it never does for a plain GTK3 window: before 64–82 of ~300 frames, after 0 on three runs. A WAYLAND_DEBUG trace pairs every GTK geometry commit with a child buffer of exactly that width (100/100). --- CLAUDE.md | 2 +- .../tao/ffi/NativeTaoLinuxWidgetBridge.kt | 29 ++ .../tao/scene/TaoComposeSceneHostLinux.kt | 285 +++++++++++++++--- .../native/linux/nucleus_tao_linux_widget.c | 86 ++++++ .../reachability-metadata.json | 7 + 5 files changed, 374 insertions(+), 35 deletions(-) diff --git a/CLAUDE.md b/CLAUDE.md index ee64dd91b..fdae2c644 100644 --- a/CLAUDE.md +++ b/CLAUDE.md @@ -36,7 +36,7 @@ Published releases are `2.5.x` (latest tag `v2.5.0`).

Mesa applies `wl_egl_window_resize` only while no back buffer is acquired — push it before `eglMakeCurrent`, never after - `decorated-window-tao` internals: `window/tao/workspace/` is the shared, `internal` core behind the multi-window archetypes — `WindowGroup` (membership, focus recency, pinning), `RelocatedContentHost` + `RelocatingSaveableStateRegistry` (`rememberSaveable` state that follows content between windows), `HostGeometry` (drop targets in physical screen px), `CrossWindowDrag` (one live drag, screen-space drag handle), `DragGhostWindow`, `ScreenPlacement` (the public capability is `TaoWindow.canPlaceOnScreen` — the native-Wayland gate — GDK reports every toplevel at `(0, 0)` and ignores moves, so anything that treats `outerBoundsPx()`'s origin as a screen coordinate must check it; the size half stays valid there; `warnScreenPlacementUnsupported` logs the gap once per process), `TransferDrag` (the native-Wayland path of every cross-window gesture: the grip starts a platform **drag-and-drop** session carrying an in-process token (`TaoPrivateTransfer`, `SAME_APP` only), the window under the pointer resolves the drop in its *own* coordinates and records it on the session, and the source acts on that record when the session ends — inverted roles versus `ScreenDrag`, because the source is told nothing about where the pointer is; the drag icon is a reduced snapshot of the dragged palette or panel, taken through `TaoWindow.contentSnapshot`). **Tab drag, two paths.** Where the app places its windows the gesture is `screenDragHandle` → `TabWorkspace.beginDrag` (ghost window, screen hit-test, tear-off; the drop resolves through `dropTargetAt(draggedScreenRectPx, pointerScreenPx, …)` — a strip the **card** has reached counts as entered, the pointer's own strip still winning, the same rule as the dock zones, and a single-tab window's drag hands its own strip band as the card), and the strip animates the reorder from `dragPointerScreenPx`. Where it cannot (native Wayland), the grip is `tabStripLocalDragHandle`: a **local** reorder driven by the pointer's travel in window px and resolved by `reorderTarget` (edge-crossing, RTL inferred from the slots), and the moment the pointer leaves the strip the gesture is handed to the platform's drag-and-drop session — `transferDragHandle(gesture = …)` takes a `TransferDragGesture` whose `onDrag` returns `true` to start it mid-gesture, from the *press* position (Compose refuses a point outside the source node). That handover is what gives every *other* window the pointer in its own coordinates, so their strips can preview the drop; nothing else can, since a client hears nothing about a pointer another window holds. `DragGhostWindow(popupFor = source)` is the preview that follows the pointer out of a compositor-placed window (`wl_subsurface`, parent-relative positions). The tab slot carries `noWindowDrag()`: the title bar's move is a compositor grab that swallows the gesture. **`TabStrip` motion** (`TabStripAnimation.kt`, a port of `sh.calvin.reorderable`'s `ReorderableRow` state machine): items are `key`ed on the tab id; a tab dragged along its **own** strip publishes no ghost (`TabTearOffDragSession` clears it while `dropPreview.group === entry.group`) and the strip draws it at the pointer's travel since the grab (`TabWorkspace.dragGrabScreenPx` / `dragPointerScreenPx`), a neighbour slides one tab-width aside (spring `StiffnessMediumLow`) when the carried tab's *edge* crosses its *centre*, and on release the session sets `pendingReorder` instead of reordering — the strip's `TabStripMotion.settle` slides the tab into the target slot, then `reorder()` + `rest()` in the same frame, so nothing jumps. The own-strip drop index is `reorderTarget` (edge-crossing rule, RTL inferred from the slots, same rule as the motion) and `insertionIndex` is direction-aware too (a right-to-left strip used to resolve every drop mirrored). Offsets are draw-time `graphicsLayer` translations, so `tabSlot` geometry is always the settled layout. Tabs open/close by width (`AnimatedVisibility`, 200 ms, `clip = false` so the carried card can leave its slot) and the stock close button delays `workspace.close` by the exit duration; `TabEntry.isEntering` marks a tab the strip has not shown yet. `TabWindows` has two app slots: `windowWrapper` wraps the whole window *including* its strip (per-window locals, background), `windowBodyWrapper` wraps only what is under the strip and is where window-level chrome goes (a `DockLayout`, activity bars) — composed at one call site for every window, so a tab change neither rebuilds it nor moves the body's relocation keys. `SatelliteWorkspace` (docking) and `TabWorkspace` (Chrome-like tabs) are both built on it — put new cross-window gestures there rather than duplicating the geometry or the drag bookkeeping. `DockLayout` (`window/tao/DockLayout.kt` + `DockSplitter.kt` + `DockTransferTarget.kt`) is the dock: sides nest in `sideOrder` (outermost first, default `DefaultDockSideOrder` = top, bottom, left, right — **not** `DockSide.entries`, whose declaration order is left, right, top, bottom), a side is either *split* (panels share its length by `Docked.weight` and its thickness by `dockExtent(side)`) or *layered* (`layeredSides`: each panel a full-length layer of its own `Docked.extent`, the way a nested split-pane tree looks), `splitter` / `panel` slots carry the app's own chrome (`DockSplitterScope.dockSplitterHandle()` is the gesture; an overflowing `requiredWidth` grip on a 1 dp line works), sides are physical and the layout forces LTR internally then restores the caller's direction for content/panels/slots, and every panel and the content are `movableContentOf` so no layout change (extent, weight, order, side, restore, side order, direction) rebuilds a subtree — the layout's inputs live in `DockLayoutState` as snapshot state because the bands are separate composables that strong skipping would otherwise skip. Extents are fitted proportionally when the window is too small (`fit`). Drop feedback lives in `DockZoneHints.kt` and **the rectangles it draws are the target**: it publishes them to `HostGeometry.zoneBoundsInWindowPx`, and `dockTargetAt(draggedScreenRectPx, pointerScreenPx)` → `dockSideEntered` resolves a drop against those, not against the window's edges — on a layered side the strip is inset behind the existing layers, and the window's own edge behind them is nothing. A zone is entered when the dragged **satellite's** edge (its window, or the tear-out ghost) is within one zone thickness of the zone's outer edge and overlaps it across the other axis — edge alignment, not overlap, or a full-height panel could never be torn out; the pointer inside a zone is a second trigger and the tie-break, else the smallest gap wins. The rects come from `DockLayoutState.landingRectPx`: the side's measured band, inside existing layers, counting the dragged panel's own side as already freed; `hintedSides` drops the side the panel is alone on in that window, so it is neither drawn nor droppable. **`dockSides`**: `Satellite(dockSides = …)` (default all four, empty = floating-only) is fixed at declaration and enforced everywhere — `dock()` and `restore()` refuse another side, `hintedSides` and `DockZoneHints` neither draw nor publish it, the drag sessions resolve through `dockTargetFor(entry, …)` and the Wayland target filters on `drag.entry.dockSides`, and the default header hides its Dock action for a floating-only palette. **`floatable = false`** is the opposite knob — a fixed panel: `undock()` refuses it, a `restore()` that floats it is ignored, the docked drag publishes no tear-out ghost and a release off every zone leaves it in place, the default header drops its Float action, and the declaration requires a docked `initialPlacement`. **`reorderable = false`** pins the rank: `dock(order)` is ignored for it (it takes the declared rank back), `insertInStack` pushes any other panel past the last pinned one (`pinnedFloor`), `dropSlotsPx` returns nothing for a pinned dragged panel and keeps the forbidden ranks as **empty** slots so a slot's index is still its rank, `hintedSides` drops its own side, `targetFor` strips the rank off a target, and `satelliteDragHandle` is inert when `canBeDragged` says a drag could not end anywhere. **Telling the two gestures apart** (what an app adapts its UI to, #663 review): `TaoWindow.canPlaceOnScreen` is the public capability (branch on it, not on `isNativeWaylandSurface`), `SatelliteScope.isCompositorPlaced` is the same answer for the window the chrome is composed in (the floating scope reads the satellite's own window through a lambda since the scope outlives it; the docked scope reads `entry.dockHost`), `SatelliteCaptionStripWidth` + the `floatingCaption` slot of `Satellite` are the strip the title bar leaves to the compositor's move — reserved and composed **only** where `isCompositorPlaced`, so an app never has to guess a width or accidentally claim the only area that can move the palette — and `SatelliteWorkspace.dragKind` (`Window` / `Transfer`) says how a drag in flight is carried, which is what tells preview code whether `dragGhost` will ever be published. `reader-dock-demo`: the book tree and the contents are `floatable = false` + `reorderable = false` + `dockSides = setOf(Right)` — furniture, and no pane can be dropped in front of them. **Ranks**: `Docked.order` is kept contiguous from 0 per (host, side) by `dock()` / `undock()` (`dock(order)` inserts at that index, `null` = the rank the entry last held on that side, remembered in `SatelliteEntry.dockMemory`, else the end), and a side with panels publishes `DockDropZone.slots` — one rect per rank, cut at the neighbours' centres, the dragged panel excluded — so `DockTarget.order` is the rank under the pointer (`dockSlotAt`), the own rank (`ownTarget`) being no target; a pointer over a stack beats a strip across its corner. `dropAt` converts a shown-rank into the full rank (closed panels keep theirs). The Wayland DnD path (`DockTransferTarget`) hit-tests the same published zones. A hand-driven `beginDrag` session must wait for the zones to be published before its first sample, or it resolves against the bare edges. `dock()` and the preview share one width (`dockSeedExtent`) and one weight (`dockSeedWeight`), so what lights up is what the release produces. **One drop preview everywhere** (`DragPreviewDefaults.kt`): the card that follows the pointer (`SatelliteGhostCard` / `TabGhostCard` on `DragPreviewSurface`) is also drawn on the space the release fills — the dock draws it at `DockLayoutState.dropRectPx(side, dragged, order, extentPx)` (empty side: the edge strip; layered: the layer at that rank; split: the share the re-divided weights give it, dividers counted), the tab strip opens a slot of the dragged tab's width (`TabStripScope.dropGhost` → `TabDropGhost`, `TabDropGhostCard`; `TabWorkspace.draggedTabWidth` reads the source slot) — and the sides merely on offer are the same surface at `hint` intensity. No insertion bars, no drop-indicator lines; a custom strip draws `dropGhost` itself, as `jewel-tabs-demo` does with a placeholder `TabData.Editor`.

AppKit, though, keeps a whole button gesture on the window that took its mouseDown — this panel — so the parent was being given a press whose end it could never see. Two ways to lose it, both measured on a tab strip's hover card: the region hit-test answers differently on the way up (the press is what dismisses the card, which re-lays out the content under the pointer), or the panel is ordered out between the two, and an ordered-out window receives nothing at all. The release then reaches no one: not the panel, not the owner's view, not the JVM. What the owner is left with is a press that never ends. Compose holds the gesture open, so the click it belonged to never happens — the tab under the pointer is not selected — and the next press is read against the stale state (`TaoComposeSceneHost` closes it out there, which is why a second click appeared to work). So the panel now tracks which buttons it forwarded: the rest of that gesture follows its press to the parent whatever the region test says, and a panel ordered out still holding one hands over the release AppKit will not deliver. --- .../src/main/native/macos/popup_panel.m | 98 ++++++++++++++++++- 1 file changed, 97 insertions(+), 1 deletion(-) diff --git a/decorated-window-tao/src/main/native/macos/popup_panel.m b/decorated-window-tao/src/main/native/macos/popup_panel.m index d815e164f..a4a173367 100644 --- a/decorated-window-tao/src/main/native/macos/popup_panel.m +++ b/decorated-window-tao/src/main/native/macos/popup_panel.m @@ -352,6 +352,12 @@ @interface NucleusTaoPopupPanel : NSPanel @property (nonatomic, strong) id outsideMonitor; // local NSEvent monitor token @property (nonatomic, strong) id outsideGlobalMonitor; // global NSEvent monitor token (standalone only) @property (nonatomic, strong) NSValue *outsideListenerVal; // jobject global ref boxed +// Buttons whose press this panel handed to its parent and whose release has +// not followed.

The dialog fades in over the scrim, so that frame sits on the knife-edge of the detection threshold: it came out bimodal on *both* layers, 0 ms on the runs that caught the faint start and ~60 ms on the runs that did not, and the comparison failed whenever the two films happened to land in different modes. They now anchor half-way through the fade, far from that edge and the same moment of the same animation either way. `hideMinHeightRatio` took the strict minimum over the fade-out. What it guards against is a surface that *stays* collapsed for the whole fade; a single short frame is a drawable caught mid-present, which an OS surface can show and a scene drawing into the window canvas never can (measured: 1 px, and half the dialog, in runs whose neighbouring frames were both full height).

Mutter culls such a parent as obscured and stops answering its `wl_surface.frame`; GDK freezes its frame clock on the unanswered callback of the last commit GTK made in that state. Two symptoms followed the #444 in-frame path: 1. The whole UI froze on maximize. The burst rendered only from GTK's `draw`, and its end was only evaluated inside the render pass — with GTK unable to paint, no frame was ever rendered again, and the coroutine continuations drained there never resumed. The burst's end (`endResizeBurstIfStale`) now runs from `onRedrawRequested` too, every `queue_draw` is watched (`askToplevelDraw`, 50 ms grace + a watchdog redraw through `DelayScheduler`) and an unanswered one drops the burst back to the event-loop path; the in-frame path is never armed while the window is maximized / tiled / fullscreen (`parentObscured()`). 2. Hover and drags were choppy while maximized although the app rendered at full rate. GDK3 holds a lone motion event until the frame clock's flush-events phase, which does not run while the clock is frozen, so motion was only delivered when another event arrived. GTK repaints the toplevel once after every maximize (`applyContentOffset`, to land the sub-surface at (0, 0)), and that commit went unanswered. The content's opaque region now always leaves its bottom row out, so the compositor keeps painting the toplevel and its callbacks keep coming. Measured with WAYLAND_DEBUG over 9 maximize/restore toggles: every one of the parent's 67 frame callbacks answered, max latency 25 ms (before: 2.5 s or never), content at 90 fps throughout, no protocol gap over 22 ms. --- CLAUDE.md | 2 +- .../dispatch/TaoMainCoroutineDispatcher.kt | 2 +- .../tao/scene/TaoComposeSceneHostLinux.kt | 146 +++++++++++++++--- .../src/main/native/linux/nucleus_tao_egl.c | 24 ++- 4 files changed, 145 insertions(+), 29 deletions(-) diff --git a/CLAUDE.md b/CLAUDE.md index fdae2c644..d44e151a8 100644 --- a/CLAUDE.md +++ b/CLAUDE.md @@ -36,7 +36,7 @@ Published releases are `2.5.x` (latest tag `v2.5.0`).

Mesa applies `wl_egl_window_resize` only while no back buffer is acquired — push it before `eglMakeCurrent`, never after. The in-frame path is **watched**: GTK only paints while the compositor feeds GDK's frame clock, and Mutter sends no frame callback to a toplevel fully covered by its own opaque content sub-surface (maximized / tiled, no shadow ring) — so a `queue_draw` unanswered for 50 ms (`IN_FRAME_DRAW_GRACE_NS`, watchdog redraw via `DelayScheduler`) drops the burst back to the event-loop render path, and the burst's end (`endResizeBurstIfStale`) runs from `onRedrawRequested` too, never only from a render. Two more rules from the same finding: the in-frame path is never armed while the window is maximized / tiled / fullscreen (`parentObscured()`), and the content's opaque region (`nativeSetOpaqueRegion`) always leaves its **bottom row** out — a toplevel fully covered by an opaque subsurface is culled by Mutter, gets no frame callback, GDK's frame clock freezes and with it the flush-events phase that delivers pointer motion (GDK3 holds a lone motion event until that phase): the app renders at full rate but hover and drags only move when another event arrives - `decorated-window-tao` internals: `window/tao/workspace/` is the shared, `internal` core behind the multi-window archetypes — `WindowGroup` (membership, focus recency, pinning), `RelocatedContentHost` + `RelocatingSaveableStateRegistry` (`rememberSaveable` state that follows content between windows), `HostGeometry` (drop targets in physical screen px), `CrossWindowDrag` (one live drag, screen-space drag handle), `DragGhostWindow`, `ScreenPlacement` (the public capability is `TaoWindow.canPlaceOnScreen` — the native-Wayland gate — GDK reports every toplevel at `(0, 0)` and ignores moves, so anything that treats `outerBoundsPx()`'s origin as a screen coordinate must check it; the size half stays valid there; `warnScreenPlacementUnsupported` logs the gap once per process), `TransferDrag` (the native-Wayland path of every cross-window gesture: the grip starts a platform **drag-and-drop** session carrying an in-process token (`TaoPrivateTransfer`, `SAME_APP` only), the window under the pointer resolves the drop in its *own* coordinates and records it on the session, and the source acts on that record when the session ends — inverted roles versus `ScreenDrag`, because the source is told nothing about where the pointer is; the drag icon is a reduced snapshot of the dragged palette or panel, taken through `TaoWindow.contentSnapshot`). **Tab drag, two paths.** Where the app places its windows the gesture is `screenDragHandle` → `TabWorkspace.beginDrag` (ghost window, screen hit-test, tear-off; the drop resolves through `dropTargetAt(draggedScreenRectPx, pointerScreenPx, …)` — a strip the **card** has reached counts as entered, the pointer's own strip still winning, the same rule as the dock zones, and a single-tab window's drag hands its own strip band as the card), and the strip animates the reorder from `dragPointerScreenPx`. Where it cannot (native Wayland), the grip is `tabStripLocalDragHandle`: a **local** reorder driven by the pointer's travel in window px and resolved by `reorderTarget` (edge-crossing, RTL inferred from the slots), and the moment the pointer leaves the strip the gesture is handed to the platform's drag-and-drop session — `transferDragHandle(gesture = …)` takes a `TransferDragGesture` whose `onDrag` returns `true` to start it mid-gesture, from the *press* position (Compose refuses a point outside the source node). That handover is what gives every *other* window the pointer in its own coordinates, so their strips can preview the drop; nothing else can, since a client hears nothing about a pointer another window holds. `DragGhostWindow(popupFor = source)` is the preview that follows the pointer out of a compositor-placed window (`wl_subsurface`, parent-relative positions). The tab slot carries `noWindowDrag()`: the title bar's move is a compositor grab that swallows the gesture. **`TabStrip` motion** (`TabStripAnimation.kt`, a port of `sh.calvin.reorderable`'s `ReorderableRow` state machine): items are `key`ed on the tab id; a tab dragged along its **own** strip publishes no ghost (`TabTearOffDragSession` clears it while `dropPreview.group === entry.group`) and the strip draws it at the pointer's travel since the grab (`TabWorkspace.dragGrabScreenPx` / `dragPointerScreenPx`), a neighbour slides one tab-width aside (spring `StiffnessMediumLow`) when the carried tab's *edge* crosses its *centre*, and on release the session sets `pendingReorder` instead of reordering — the strip's `TabStripMotion.settle` slides the tab into the target slot, then `reorder()` + `rest()` in the same frame, so nothing jumps. The own-strip drop index is `reorderTarget` (edge-crossing rule, RTL inferred from the slots, same rule as the motion) and `insertionIndex` is direction-aware too (a right-to-left strip used to resolve every drop mirrored). Offsets are draw-time `graphicsLayer` translations, so `tabSlot` geometry is always the settled layout. Tabs open/close by width (`AnimatedVisibility`, 200 ms, `clip = false` so the carried card can leave its slot) and the stock close button delays `workspace.close` by the exit duration; `TabEntry.isEntering` marks a tab the strip has not shown yet. `TabWindows` has two app slots: `windowWrapper` wraps the whole window *including* its strip (per-window locals, background), `windowBodyWrapper` wraps only what is under the strip and is where window-level chrome goes (a `DockLayout`, activity bars) — composed at one call site for every window, so a tab change neither rebuilds it nor moves the body's relocation keys. `SatelliteWorkspace` (docking) and `TabWorkspace` (Chrome-like tabs) are both built on it — put new cross-window gestures there rather than duplicating the geometry or the drag bookkeeping. `DockLayout` (`window/tao/DockLayout.kt` + `DockSplitter.kt` + `DockTransferTarget.kt`) is the dock: sides nest in `sideOrder` (outermost first, default `DefaultDockSideOrder` = top, bottom, left, right — **not** `DockSide.entries`, whose declaration order is left, right, top, bottom), a side is either *split* (panels share its length by `Docked.weight` and its thickness by `dockExtent(side)`) or *layered* (`layeredSides`: each panel a full-length layer of its own `Docked.extent`, the way a nested split-pane tree looks), `splitter` / `panel` slots carry the app's own chrome (`DockSplitterScope.dockSplitterHandle()` is the gesture; an overflowing `requiredWidth` grip on a 1 dp line works), sides are physical and the layout forces LTR internally then restores the caller's direction for content/panels/slots, and every panel and the content are `movableContentOf` so no layout change (extent, weight, order, side, restore, side order, direction) rebuilds a subtree — the layout's inputs live in `DockLayoutState` as snapshot state because the bands are separate composables that strong skipping would otherwise skip. Extents are fitted proportionally when the window is too small (`fit`). Drop feedback lives in `DockZoneHints.kt` and **the rectangles it draws are the target**: it publishes them to `HostGeometry.zoneBoundsInWindowPx`, and `dockTargetAt(draggedScreenRectPx, pointerScreenPx)` → `dockSideEntered` resolves a drop against those, not against the window's edges — on a layered side the strip is inset behind the existing layers, and the window's own edge behind them is nothing. A zone is entered when the dragged **satellite's** edge (its window, or the tear-out ghost) is within one zone thickness of the zone's outer edge and overlaps it across the other axis — edge alignment, not overlap, or a full-height panel could never be torn out; the pointer inside a zone is a second trigger and the tie-break, else the smallest gap wins. The rects come from `DockLayoutState.landingRectPx`: the side's measured band, inside existing layers, counting the dragged panel's own side as already freed; `hintedSides` drops the side the panel is alone on in that window, so it is neither drawn nor droppable. **`dockSides`**: `Satellite(dockSides = …)` (default all four, empty = floating-only) is fixed at declaration and enforced everywhere — `dock()` and `restore()` refuse another side, `hintedSides` and `DockZoneHints` neither draw nor publish it, the drag sessions resolve through `dockTargetFor(entry, …)` and the Wayland target filters on `drag.entry.dockSides`, and the default header hides its Dock action for a floating-only palette. **`floatable = false`** is the opposite knob — a fixed panel: `undock()` refuses it, a `restore()` that floats it is ignored, the docked drag publishes no tear-out ghost and a release off every zone leaves it in place, the default header drops its Float action, and the declaration requires a docked `initialPlacement`. **`reorderable = false`** pins the rank: `dock(order)` is ignored for it (it takes the declared rank back), `insertInStack` pushes any other panel past the last pinned one (`pinnedFloor`), `dropSlotsPx` returns nothing for a pinned dragged panel and keeps the forbidden ranks as **empty** slots so a slot's index is still its rank, `hintedSides` drops its own side, `targetFor` strips the rank off a target, and `satelliteDragHandle` is inert when `canBeDragged` says a drag could not end anywhere. **Telling the two gestures apart** (what an app adapts its UI to, #663 review): `TaoWindow.canPlaceOnScreen` is the public capability (branch on it, not on `isNativeWaylandSurface`), `SatelliteScope.isCompositorPlaced` is the same answer for the window the chrome is composed in (the floating scope reads the satellite's own window through a lambda since the scope outlives it; the docked scope reads `entry.dockHost`), `SatelliteCaptionStripWidth` + the `floatingCaption` slot of `Satellite` are the strip the title bar leaves to the compositor's move — reserved and composed **only** where `isCompositorPlaced`, so an app never has to guess a width or accidentally claim the only area that can move the palette — and `SatelliteWorkspace.dragKind` (`Window` / `Transfer`) says how a drag in flight is carried, which is what tells preview code whether `dragGhost` will ever be published. `reader-dock-demo`: the book tree and the contents are `floatable = false` + `reorderable = false` + `dockSides = setOf(Right)` — furniture, and no pane can be dropped in front of them. **Ranks**: `Docked.order` is kept contiguous from 0 per (host, side) by `dock()` / `undock()` (`dock(order)` inserts at that index, `null` = the rank the entry last held on that side, remembered in `SatelliteEntry.dockMemory`, else the end), and a side with panels publishes `DockDropZone.slots` — one rect per rank, cut at the neighbours' centres, the dragged panel excluded — so `DockTarget.order` is the rank under the pointer (`dockSlotAt`), the own rank (`ownTarget`) being no target; a pointer over a stack beats a strip across its corner. `dropAt` converts a shown-rank into the full rank (closed panels keep theirs). The Wayland DnD path (`DockTransferTarget`) hit-tests the same published zones. A hand-driven `beginDrag` session must wait for the zones to be published before its first sample, or it resolves against the bare edges. `dock()` and the preview share one width (`dockSeedExtent`) and one weight (`dockSeedWeight`), so what lights up is what the release produces. **One drop preview everywhere** (`DragPreviewDefaults.kt`): the card that follows the pointer (`SatelliteGhostCard` / `TabGhostCard` on `DragPreviewSurface`) is also drawn on the space the release fills — the dock draws it at `DockLayoutState.dropRectPx(side, dragged, order, extentPx)` (empty side: the edge strip; layered: the layer at that rank; split: the share the re-divided weights give it, dividers counted), the tab strip opens a slot of the dragged tab's width (`TabStripScope.dropGhost` → `TabDropGhost`, `TabDropGhostCard`; `TabWorkspace.draggedTabWidth` reads the source slot) — and the sides merely on offer are the same surface at `hint` intensity. No insertion bars, no drop-indicator lines; a custom strip draws `dropGhost` itself, as `jewel-tabs-demo` does with a placeholder `TabData.Editor`.

Natives are still built and verified; the JARs would be unusable otherwise. Nothing else in the publish graph runs tests: `publishToMavenLocal` pulls in `compileKotlin` → `jar`/`sourcesJar`/`javadoc` → `pom`/`publish` and neither `test`, `apiCheck` nor `detekt`. `release-tag-info` is the single place that classifies a tag. It also rejects anything that is not `v`: every module derives its version with `GITHUB_REF.removePrefix("refs/tags/v")`, so a bare `dev-2026…` tag would have published a version literally named `refs/tags/dev-2026…` — permanently, on Central. Dev tags are excluded from `release-desktop` / `release-graalvm`: they publish libraries, they should cut no GitHub release and burn no packaging matrix. `validate-release-ref` now derives the branch a prerelease tag must live on from the tag itself (`v2.6.0-rc.1` → `nucleus-2.6`). The pinned default was still `nucleus-2.0`, a branch that no longer exists on origin, so the next rc would have failed to fetch — the guard was protecting the previous release line. --- .claude/skills/tag-dev/SKILL.md | 64 +++++++++++++++++++ .github/actions/release-tag-info/action.yml | 64 +++++++++++++++++++ .../actions/validate-release-ref/action.yml | 31 +++++++-- .github/workflows/publish-maven.yaml | 14 +++- .github/workflows/publish-plugin.yaml | 13 +++- .github/workflows/release-desktop.yaml | 3 + .github/workflows/release-graalvm.yaml | 3 + CLAUDE.md | 20 ++++++ 8 files changed, 205 insertions(+), 7 deletions(-) create mode 100644 .claude/skills/tag-dev/SKILL.md create mode 100644 .github/actions/release-tag-info/action.yml diff --git a/.claude/skills/tag-dev/SKILL.md b/.claude/skills/tag-dev/SKILL.md new file mode 100644 index 000000000..a37bc4613 --- /dev/null +++ b/.claude/skills/tag-dev/SKILL.md @@ -0,0 +1,64 @@ +--- +name: tag-dev +description: Create and push a timestamped dev tag for the Nucleus 2.6 branch in the format v2.6.0-dev-YYYYMMDDHHMM, publishing runtime modules to Maven Central and the plugin to the Gradle Plugin Portal without running preMerge.

Mesa applies `wl_egl_window_resize` only while no back buffer is acquired — push it before `eglMakeCurrent`, never after. The in-frame path is **watched**: GTK only paints while the compositor feeds GDK's frame clock, and Mutter sends no frame callback to a toplevel fully covered by its own opaque content sub-surface (maximized / tiled, no shadow ring) — so a `queue_draw` unanswered for 50 ms (`IN_FRAME_DRAW_GRACE_NS`, watchdog redraw via `DelayScheduler`) drops the burst back to the event-loop render path, and the burst's end (`endResizeBurstIfStale`) runs from `onRedrawRequested` too, never only from a render. Two more rules from the same finding: the in-frame path is never armed while the window is maximized / tiled / fullscreen (`parentObscured()`), and the content's opaque region (`nativeSetOpaqueRegion`) always leaves its **bottom row** out — a toplevel fully covered by an opaque subsurface is culled by Mutter, gets no frame callback, GDK's frame clock freezes and with it the flush-events phase that delivers pointer motion (GDK3 holds a lone motion event until that phase): the app renders at full rate but hover and drags only move when another event arrives -- `decorated-window-tao` internals: `window/tao/workspace/` is the shared, `internal` core behind the multi-window archetypes — `WindowGroup` (membership, focus recency, pinning), `RelocatedContentHost` + `RelocatingSaveableStateRegistry` (`rememberSaveable` state that follows content between windows), `HostGeometry` (drop targets in physical screen px), `CrossWindowDrag` (one live drag, screen-space drag handle), `DragGhostWindow`, `ScreenPlacement` (the public capability is `TaoWindow.canPlaceOnScreen` — the native-Wayland gate — GDK reports every toplevel at `(0, 0)` and ignores moves, so anything that treats `outerBoundsPx()`'s origin as a screen coordinate must check it; the size half stays valid there; `warnScreenPlacementUnsupported` logs the gap once per process), `TransferDrag` (the native-Wayland path of every cross-window gesture: the grip starts a platform **drag-and-drop** session carrying an in-process token (`TaoPrivateTransfer`, `SAME_APP` only), the window under the pointer resolves the drop in its *own* coordinates and records it on the session, and the source acts on that record when the session ends — inverted roles versus `ScreenDrag`, because the source is told nothing about where the pointer is; the drag icon is a reduced snapshot of the dragged palette or panel, taken through `TaoWindow.contentSnapshot`). **Tab drag, two paths.** Where the app places its windows the gesture is `screenDragHandle` → `TabWorkspace.beginDrag` (ghost window, screen hit-test, tear-off; the drop resolves through `dropTargetAt(draggedScreenRectPx, pointerScreenPx, …)` — a strip the **card** has reached counts as entered, the pointer's own strip still winning, the same rule as the dock zones, and a single-tab window's drag hands its own strip band as the card), and the strip animates the reorder from `dragPointerScreenPx`. Where it cannot (native Wayland), the grip is `tabStripLocalDragHandle`: a **local** reorder driven by the pointer's travel in window px and resolved by `reorderTarget` (edge-crossing, RTL inferred from the slots), and the moment the pointer leaves the strip the gesture is handed to the platform's drag-and-drop session — `transferDragHandle(gesture = …)` takes a `TransferDragGesture` whose `onDrag` returns `true` to start it mid-gesture, from the *press* position (Compose refuses a point outside the source node). That handover is what gives every *other* window the pointer in its own coordinates, so their strips can preview the drop; nothing else can, since a client hears nothing about a pointer another window holds. `DragGhostWindow(popupFor = source)` is the preview that follows the pointer out of a compositor-placed window (`wl_subsurface`, parent-relative positions). The tab slot carries `noWindowDrag()`: the title bar's move is a compositor grab that swallows the gesture. **`TabStrip` motion** (`TabStripAnimation.kt`, a port of `sh.calvin.reorderable`'s `ReorderableRow` state machine): items are `key`ed on the tab id; a tab dragged along its **own** strip publishes no ghost (`TabTearOffDragSession` clears it while `dropPreview.group === entry.group`) and the strip draws it at the pointer's travel since the grab (`TabWorkspace.dragGrabScreenPx` / `dragPointerScreenPx`), a neighbour slides one tab-width aside (spring `StiffnessMediumLow`) when the carried tab's *edge* crosses its *centre*, and on release the session sets `pendingReorder` instead of reordering — the strip's `TabStripMotion.settle` slides the tab into the target slot, then `reorder()` + `rest()` in the same frame, so nothing jumps. The own-strip drop index is `reorderTarget` (edge-crossing rule, RTL inferred from the slots, same rule as the motion) and `insertionIndex` is direction-aware too (a right-to-left strip used to resolve every drop mirrored). Offsets are draw-time `graphicsLayer` translations, so `tabSlot` geometry is always the settled layout. Tabs open/close by width (`AnimatedVisibility`, 200 ms, `clip = false` so the carried card can leave its slot) and the stock close button delays `workspace.close` by the exit duration; `TabEntry.isEntering` marks a tab the strip has not shown yet. `TabWindows` has two app slots: `windowWrapper` wraps the whole window *including* its strip (per-window locals, background), `windowBodyWrapper` wraps only what is under the strip and is where window-level chrome goes (a `DockLayout`, activity bars) — composed at one call site for every window, so a tab change neither rebuilds it nor moves the body's relocation keys. `SatelliteWorkspace` (docking) and `TabWorkspace` (Chrome-like tabs) are both built on it — put new cross-window gestures there rather than duplicating the geometry or the drag bookkeeping. `DockLayout` (`window/tao/DockLayout.kt` + `DockSplitter.kt` + `DockTransferTarget.kt`) is the dock: sides nest in `sideOrder` (outermost first, default `DefaultDockSideOrder` = top, bottom, left, right — **not** `DockSide.entries`, whose declaration order is left, right, top, bottom), a side is either *split* (panels share its length by `Docked.weight` and its thickness by `dockExtent(side)`) or *layered* (`layeredSides`: each panel a full-length layer of its own `Docked.extent`, the way a nested split-pane tree looks), `splitter` / `panel` slots carry the app's own chrome (`DockSplitterScope.dockSplitterHandle()` is the gesture; an overflowing `requiredWidth` grip on a 1 dp line works), sides are physical and the layout forces LTR internally then restores the caller's direction for content/panels/slots, and every panel and the content are `movableContentOf` so no layout change (extent, weight, order, side, restore, side order, direction) rebuilds a subtree — the layout's inputs live in `DockLayoutState` as snapshot state because the bands are separate composables that strong skipping would otherwise skip. Extents are fitted proportionally when the window is too small (`fit`). Drop feedback lives in `DockZoneHints.kt` and **the rectangles it draws are the target**: it publishes them to `HostGeometry.zoneBoundsInWindowPx`, and `dockTargetAt(draggedScreenRectPx, pointerScreenPx)` → `dockSideEntered` resolves a drop against those, not against the window's edges — on a layered side the strip is inset behind the existing layers, and the window's own edge behind them is nothing. A zone is entered when the dragged **satellite's** edge (its window, or the tear-out ghost) is within one zone thickness of the zone's outer edge and overlaps it across the other axis — edge alignment, not overlap, or a full-height panel could never be torn out; the pointer inside a zone is a second trigger and the tie-break, else the smallest gap wins. The rects come from `DockLayoutState.landingRectPx`: the side's measured band, inside existing layers, counting the dragged panel's own side as already freed; `hintedSides` drops the side the panel is alone on in that window, so it is neither drawn nor droppable. **`dockSides`**: `Satellite(dockSides = …)` (default all four, empty = floating-only) is fixed at declaration and enforced everywhere — `dock()` and `restore()` refuse another side, `hintedSides` and `DockZoneHints` neither draw nor publish it, the drag sessions resolve through `dockTargetFor(entry, …)` and the Wayland target filters on `drag.entry.dockSides`, and the default header hides its Dock action for a floating-only palette. **`floatable = false`** is the opposite knob — a fixed panel: `undock()` refuses it, a `restore()` that floats it is ignored, the docked drag publishes no tear-out ghost and a release off every zone leaves it in place, the default header drops its Float action, and the declaration requires a docked `initialPlacement`. **`reorderable = false`** pins the rank: `dock(order)` is ignored for it (it takes the declared rank back), `insertInStack` pushes any other panel past the last pinned one (`pinnedFloor`), `dropSlotsPx` returns nothing for a pinned dragged panel and keeps the forbidden ranks as **empty** slots so a slot's index is still its rank, `hintedSides` drops its own side, `targetFor` strips the rank off a target, and `satelliteDragHandle` is inert when `canBeDragged` says a drag could not end anywhere. **Telling the two gestures apart** (what an app adapts its UI to, #663 review): `TaoWindow.canPlaceOnScreen` is the public capability (branch on it, not on `isNativeWaylandSurface`), `SatelliteScope.isCompositorPlaced` is the same answer for the window the chrome is composed in (the floating scope reads the satellite's own window through a lambda since the scope outlives it; the docked scope reads `entry.dockHost`), `SatelliteCaptionStripWidth` + the `floatingCaption` slot of `Satellite` are the strip the title bar leaves to the compositor's move — reserved and composed **only** where `isCompositorPlaced`, so an app never has to guess a width or accidentally claim the only area that can move the palette — and `SatelliteWorkspace.dragKind` (`Window` / `Transfer`) says how a drag in flight is carried, which is what tells preview code whether `dragGhost` will ever be published. `reader-dock-demo`: the book tree and the contents are `floatable = false` + `reorderable = false` + `dockSides = setOf(Right)` — furniture, and no pane can be dropped in front of them. **Ranks**: `Docked.order` is kept contiguous from 0 per (host, side) by `dock()` / `undock()` (`dock(order)` inserts at that index, `null` = the rank the entry last held on that side, remembered in `SatelliteEntry.dockMemory`, else the end), and a side with panels publishes `DockDropZone.slots` — one rect per rank, cut at the neighbours' centres, the dragged panel excluded — so `DockTarget.order` is the rank under the pointer (`dockSlotAt`), the own rank (`ownTarget`) being no target; a pointer over a stack beats a strip across its corner. `dropAt` converts a shown-rank into the full rank (closed panels keep theirs). The Wayland DnD path (`DockTransferTarget`) hit-tests the same published zones. A hand-driven `beginDrag` session must wait for the zones to be published before its first sample, or it resolves against the bare edges. `dock()` and the preview share one width (`dockSeedExtent`) and one weight (`dockSeedWeight`), so what lights up is what the release produces. **One drop preview everywhere** (`DragPreviewDefaults.kt`): the card that follows the pointer (`SatelliteGhostCard` / `TabGhostCard` on `DragPreviewSurface`) is also drawn on the space the release fills — the dock draws it at `DockLayoutState.dropRectPx(side, dragged, order, extentPx)` (empty side: the edge strip; layered: the layer at that rank; split: the share the re-divided weights give it, dividers counted), the tab strip opens a slot of the dragged tab's width (`TabStripScope.dropGhost` → `TabDropGhost`, `TabDropGhostCard`; `TabWorkspace.draggedTabWidth` reads the source slot) — and the sides merely on offer are the same surface at `hint` intensity. No insertion bars, no drop-indicator lines; a custom strip draws `dropGhost` itself, as `jewel-tabs-demo` does with a placeholder `TabData.Editor`. Headful coverage: `DockLayoutHeadfulCases` (robot splitter drags) + `DockLayoutMonkeyHeadfulCases` (profiles × seeds, `-Dnucleus.tao.headful.filter="dock layout"`). +- `decorated-window-tao` internals: `window/tao/workspace/` is the shared, `internal` core behind the multi-window archetypes — `WindowGroup` (membership, focus recency, pinning), `RelocatedContentHost` + `RelocatingSaveableStateRegistry` (`rememberSaveable` state that follows content between windows), `HostGeometry` (drop targets in physical screen px), `CrossWindowDrag` (one live drag, screen-space drag handle), `DragGhostWindow`, `ScreenPlacement` (the public capability is `TaoWindow.canPlaceOnScreen` — the native-Wayland gate — GDK reports every toplevel at `(0, 0)` and ignores moves, so anything that treats `outerBoundsPx()`'s origin as a screen coordinate must check it; the size half stays valid there; `warnScreenPlacementUnsupported` logs the gap once per process), `TransferDrag` (the native-Wayland path of every cross-window gesture: the grip starts a platform **drag-and-drop** session carrying an in-process token (`TaoPrivateTransfer`, `SAME_APP` only), the window under the pointer resolves the drop in its *own* coordinates and records it on the session, and the source acts on that record when the session ends — inverted roles versus `ScreenDrag`, because the source is told nothing about where the pointer is; the drag icon is a reduced snapshot of the dragged palette or panel, taken through `TaoWindow.contentSnapshot`). **Tab drag, two paths.** Where the app places its windows the gesture is `screenDragHandle` → `TabWorkspace.beginDrag` (ghost window, screen hit-test, tear-off; the drop resolves through `dropTargetAt(draggedScreenRectPx, pointerScreenPx, …)` — a strip the **card** has reached counts as entered, the pointer's own strip still winning, the same rule as the dock zones, and a single-tab window's drag hands its own strip band as the card), and the strip animates the reorder from `dragPointerScreenPx`.

No insertion bars, no drop-indicator lines; a custom strip draws `dropGhost` itself, as `jewel-tabs-demo` does with a placeholder `TabData.Editor`. The card under the pointer is the `dragGhost` slot of `TabWindows` (default `TabDragGhostCard`) and the card in the landing slot is `TabStrip(dropGhostCard)` (default `TabDropGhostCard`; `TabDropGhost.tab` is the entry); both defaults are the public `TabGhostCard(tab, modifier)`, the shape an app's own card takes so one composable serves both slots. `WorkspaceDragKind` (`Window` / `Transfer`) is shared by `SatelliteWorkspace.dragKind` and `TabWorkspace.dragKind`, `Transfer` only once the platform session exists (a tab merely held in its strip on Wayland reports `null`); on native Wayland `dragGhost` is never published and the slot never composes. The ghost is laid out in the **source strip's / dock's** direction, for both archetypes: `publishHostGeometry` records `LocalLayoutDirection` on `HostGeometry.layoutDirection`, the drag session copies it onto `TabDragGhost` / `DragGhost`, and `DragGhostWindow(layoutDirection)` provides it in the ghost scene (a scene of its own re-provides the global direction over the bridged locals). The ghost content has the ghost window's `TaoDecoratedWindowScope`; `nucleus-application` wraps the `dragGhost` slot in `bindNucleusContent` (Nucleus locals, ghost direction) but never in the app's `windowWrapper`, which paints a window background. `DragController.active` is snapshot state so `dragKind` is observable. `TabWindows` and `DragGhostWindow` are `@ComposableOpenTarget(-1)` with `@UiComposable` lambdas (#636 — the inferred target flipped with incremental compilation, so it is pinned). `TabStrip` has per-tab `tabLeading` / `tabTrailing` slots (`Modifier.slotGap`: the 6 dp gap is charged only when the slot measured wider than 0, so the stock chip is unchanged and an empty slot costs nothing), the drop slot is sized by the strip whatever `dropGhostCard` draws, a tab opens/closes clipped to its slot only while `MutableTransitionState.isIdle` is false (AnimatedVisibility's own `clip` stays on for good and would cut a carried card), `TabPreview(tab, modifier)` is the one composable for a tab's thumbnail (the stock hover card is built on it), and `TabEntry.thumbnail` is app-assignable — assign before the tab is shown, from an effect next to the `Tab` declaration, since `restore()` creates no entries and the recorder's capture replaces whatever is there when the tab is shown.

The real terminate runs once the event loop is gone. - TaoApplication.requestQuit: windows are asked newest first, the app exits once all of them closed (it used to stay alive windowless), a window that stays open cancels the quit, repeated requests while one is in flight are ignored, and a window opened during the quit (a "Save?" dialog) defers the exit until it closes. - exitApplication() called from a close request during a quit is that window's consent, not an exit overriding another window's veto (the common `onCloseRequest = ::exitApplication` main window used to discard unsaved documents). - Framework-owned windows (workspace satellites, tab windows, drag ghosts) are left out: a quit no longer empties the tab workspace or closes the palettes before the session is saved. - TaoApplication.isQuitting / NucleusApplicationScope.isQuitting (Electron's before-quit flag) so hide-to-tray close handlers can let a real quit through. Verified with a 59-case macOS e2e matrix (Cmd+Q via CGEventPostToPid, Dock quit, menu Quit, logout/restart/shutdown Apple events with their replies) against nucleus-2.6 and the original PR.

Date: Wed, 23 Sep 2026 23:21:17 +0300 Subject: [PATCH 172/233] feat(tao): consume ANGLE as a Maven dependency, built for D3D11 only The Windows ANGLE runtime was extracted at build time from a pinned Electron release: 292 MB of download for 8.5 MB of DLL, and a libGLESv2.dll carrying the Vulkan, desktop-GL/WGL and D3D9 backends, SwiftShader, the OpenCL frontend and the GLES1 emulation -- none of which the Tao backend can reach. It only ever asks for EGL_PLATFORM_ANGLE_TYPE_D3D11_ANGLE (hardware, falling back to WARP) plus EGL_EXT_device_query and EGL_ANGLE_d3d_texture_client_buffer; DirectComposition is driven by nucleus_tao_windows_overlay_dcomp.cpp itself, so ANGLE never sees an IDCompositionSurface as an EGL native window. The DLLs now come from dev.nucleusframework:nucleus.angle-natives, published from the NucleusFramework/angle fork of google/angle, which builds the unmodified upstream sources of the release branch stable Chrome ships with everything else disabled at the GN level. libGLESv2.dll drops from 8.0 MB to 5.6 MB, and gdi32 leaves the import table with the WGL backend. The artifact version is the Chromium branch number, so ANGLE moves on its own cadence rather than Nucleus'. The jar lays the libraries out under nucleus/native/win32-{x64,aarch64}/, which is where NativeLibraryLoader already resolves them from the classpath, so declaring the dependency is the whole integration -- no loader change, and the GraalVM `nucleus/**` resource glob covers them wherever on the classpath they sit. This also removes a long-standing trap: the DLLs were gitignored build outputs, so a fresh worktree had none and every Tao app died at startup until they were copied in by hand. --- .github/workflows/build-natives.yaml | 11 --- .github/workflows/pre-merge.yaml | 4 - .github/workflows/publish-maven.yaml | 4 - THIRD_PARTY_NOTICES.md | 23 ++++-- decorated-window-tao/build.gradle.kts | 6 ++ .../src/main/native/windows/fetch-angle.sh | 81 ------------------- gradle/libs.versions.toml | 4 + 7 files changed, 26 insertions(+), 107 deletions(-) delete mode 100644 decorated-window-tao/src/main/native/windows/fetch-angle.sh diff --git a/.github/workflows/build-natives.yaml b/.github/workflows/build-natives.yaml index ea5b61bc8..02f288f2d 100644 --- a/.github/workflows/build-natives.yaml +++ b/.github/workflows/build-natives.yaml @@ -125,15 +125,6 @@ jobs: shell: cmd run: call decorated-window-tao\src\main\native\windows\build.bat - # ANGLE (libEGL + libGLESv2) backs the Tao Windows Direct3D-11 render path. - # Fetched from a pinned Electron release with SHA-256 verification (never - # committed — see .gitignore).

Pre-existing gaps are grandfathered in per-module `/detekt-baseline.xml` files — any *new* undocumented public class or function fails the build. Do not regenerate a baseline to silence a new finding; write the KDoc. `UndocumentedPublicProperty` stays off because the generated icon/symbol catalogs (`sf-symbols`, `freedesktop-icons`) would swamp it - **Logging**: `java.util.logging` is the single facade for every runtime module — no SLF4J dependency forced on consumers, no raw `println` / `System.err` in `src/main`. Logger names must be the fully-qualified class name (or an explicit `dev.nucleusframework.*` string) so the whole framework sits under one JUL namespace. `allowNucleusRuntimeLogging = true` is an opt-in convenience that raises the `dev.nucleusframework` logger to `nucleusLoggingLevel` and attaches a colored console handler; apps that configure JUL themselves (`logging.properties`, `jul-to-slf4j`) leave it `false` and Nucleus never touches the JUL configuration - `decorated-window-tao` is the only window backend (no AWT, native event-loop-driven, true Windows fullscreen, GraalVM native-image first-class). The AWT-based backends (`decorated-window-awt` / `-jbr` / `-jni`), `NucleusBackend`, `LocalNucleusBackend`, the `backend =` parameter of `nucleusApplication`, and `NucleusWindowUnsafe.awtWindow` / `awtDialog` were all removed in 2.6. Compose Desktop's AWT `Window` / `Dialog` / `Tray` are unsupported — use `DecoratedWindow`, `HostedWindow` / `HostedDialog`, and an AWT-free tray +- **Event-loop watchdog** (#643): a stalled loop produces no exception — to the JVM the thread is a healthy `RUNNABLE` / `_thread_in_native` — and `TaoApplication.rethrowPendingFatal` sits *after* `nativeRunBlocking`, which a deadlocked loop never leaves, so #640 froze silently. `TaoEventLoopWatchdog` is a min-priority daemon thread that polls `IsHungAppWindow` (`NativeTaoBridge.nativeIsWindowHung`) every 2 s and logs `SEVERE` + a full thread dump once a window has been hung past the grace period on top of Windows' own ~5 s threshold. The probe is a pure OS-state query — it sends nothing to the loop, unlike a `SendMessageTimeout(WM_NULL)` probe, whose inline sent message is exactly the re-entrancy that deadlocked #640. HWNDs are cached on `WINDOW_READY` from the event-loop thread: resolving one later goes through the native `WINDOWS` map, whose lock a stalled loop may hold. `-Dnucleus.tao.watchdog=false` disables it, `-Dnucleus.tao.watchdogGraceMs=` retunes it, `-Dnucleus.tao.watchdogDialog=true` also pops the native error dialog (from the watchdog thread — the loop thread is the stuck one, #622's constraint). Windows only: macOS has no public "not responding" query and X11's `_NET_WM_PING` perturbs the loop it observes - **macOS trackpad on Tao** (#652–#654): scroll deltas are AWT-shaped (`preciseWheelRotation`, no display scale). Trackpad gestures reach Compose as `PanStart` / `PanMove` / `PanEnd` (`panOffset` = AWT delta × 10 dp), wheel notches as `Scroll`; foundation's `Modifier.scrollable` handles both. Custom handlers that only listen for `PointerEventType.Scroll` must also handle Pan, or the app can set `-Dnucleus.tao.trackpadPanEvents=false` to get AWT-style `Scroll` for everything. Everything scroll-related enters the scene through `TaoSceneScrollRouter` (window + NSPanel popups); the phase wire (Rust `SCROLL_GESTURE_*`, `popup_panel.m`, `TaoScrollGesturePhase`) is guarded by `TaoScrollWireDriftTest` - macOS Liquid Glass enabled by default via `macOsSdkVersion = "26.0"` (vtool SDK patching) - **PKG has two channels**, chosen by `macOS { pkg { appStore } }` (default `true`); whether `TargetFormat.Pkg` is a store format is `JvmApplicationDistributions.isSandboxed(format)`, not an enum property. App Store PKG = sandboxed pipeline, "3rd Party Mac Developer" certificates, `productsign` after the build, never notarized (Transporter upload). `appStore = false` = Developer ID PKG on the DMG pipeline (#249): electron-builder signs the installer itself from `pkg.identity` = the **bare** `NAME (TEAMID)` (it prepends "Developer ID Installer" and rejects a prefixed qualifier; `CSC_IDENTITY_AUTO_DISCOVERY=false` means no identity ⇒ silently unsigned, which the task catches with `pkgutil --check-signature`), a DSL keychain travels as `CSC_KEYCHAIN`, and `notarizePkg` notarizes the `.pkg`. `pkg { preInstall / postInstall }` are staged in `/build/pkg-scripts` for `pkgbuild --scripts` (shebang required); the App Store rejects install scripts (error 90254), so they require `appStore = false`. **The staged `preinstall` / `postinstall` are Nucleus shims, not the app's script**: electron-builder sets `BundlePre/PostInstallScriptPath` *and* passes `--scripts`, so `PackageInfo` declares each script twice and Installer runs it twice (confirmed on a real install). The shim skips the per-bundle pass (`$2` is the `.app`) and execs the app's copy, staged as `nucleus-app-pre` / `nucleus-app-post` — names electron-builder's `name.includes("preinstall")` scan must not match. Runtime: gate sandbox-sensitive features on `ExecutableRuntime.isSandboxed()` (`APP_SANDBOX_CONTAINER_ID`), never on `isPkg()` — that is also what makes a Developer ID PKG self-updatable (`NucleusUpdater.isUpdateSupported`) while the App Store build stays excluded diff --git a/README.md b/README.md index 0d25ddef1..30aa7b36c 100644 --- a/README.md +++ b/README.md @@ -107,7 +107,7 @@ Nucleus builds on Compose Multiplatform and requires: | JDK | 17+ (25+ for AOT cache) | Any vendor — no JetBrains Runtime needed | | Kotlin | 2.4.10+ | This repo builds with Kotlin 2.4.10 | | Compose Multiplatform | 1.12.0 | Required by the 2.5 line; will not run on 1.11.x | -| Gradle | 9.0+ | Bundled wrapper is Gradle 9.4.0 | +| Gradle | 9.0+ | Bundled wrapper is Gradle 9.8.0-rc-3 | ## Platform support diff --git a/build.gradle.kts b/build.gradle.kts index 7e8dc50d1..9cc68ccf7 100644 --- a/build.gradle.kts +++ b/build.gradle.kts @@ -50,7 +50,7 @@ apiValidation { // The per-module `buildNative*` tasks themselves are wired by the // `nucleus.native-module` convention plugin (see buildSrc). -val buildNative by tasks.registering { +val buildNative = tasks.register("buildNative") { group = "build" description = "Builds native libraries for the current host platform." } @@ -103,7 +103,7 @@ subprojects { .get() .pluginId, ) - rootProject.dependencies.add("kover", project(path)) + rootProject.dependencies.add("kover", dependencyFactory.create(path)) } pluginManager.withPlugin("org.jetbrains.kotlin.multiplatform") { apply( @@ -112,7 +112,7 @@ subprojects { .get() .pluginId, ) - rootProject.dependencies.add("kover", project(path)) + rootProject.dependencies.add("kover", dependencyFactory.create(path)) } } @@ -224,7 +224,7 @@ tasks.register("reformatAll") { dependsOn(gradle.includedBuild("plugin-build").task(":plugin:ktlintFormat")) } -val publishAllToMavenLocal by tasks.registering { +val publishAllToMavenLocal = tasks.register("publishAllToMavenLocal") { group = "publishing" description = "Publishes all runtime libraries and the Gradle plugin to Maven Local." diff --git a/decorated-window-tao/build.gradle.kts b/decorated-window-tao/build.gradle.kts index d167fd30a..6e453d3e0 100644 --- a/decorated-window-tao/build.gradle.kts +++ b/decorated-window-tao/build.gradle.kts @@ -105,7 +105,7 @@ tasks.named("jar") { } } -val taoTestClassesJar by tasks.registering(Jar::class) { +val taoTestClassesJar = tasks.register("taoTestClassesJar") { archiveClassifier.set("test-classes") from(sourceSets.test.get().output) } @@ -116,7 +116,7 @@ val taoTestClassesJar by tasks.registering(Jar::class) { // NoClassDefFoundError the first time the suite reaches the code that uses it — // which is how `examples/tao-native-test` lost Material 3 and took the whole // GraalVM job down with the Tao main thread. -val taoTestArtifacts: Configuration by configurations.creating { +val taoTestArtifacts: Configuration = configurations.create("taoTestArtifacts") { isCanBeConsumed = true isCanBeResolved = false extendsFrom(configurations.testImplementation.get()) @@ -136,7 +136,7 @@ artifacts { val taoHeadfulKoverReport = layout.buildDirectory.file("kover/bin-reports/taoHeadful.ic") -val taoHeadfulTest by tasks.registering(JavaExec::class) { +val taoHeadfulTest = tasks.register("taoHeadfulTest") { description = "Runs the stage-2 real-window Tao test suite (requires a display)" group = "verification" classpath = sourceSets.test.get().runtimeClasspath @@ -224,7 +224,7 @@ val taoHeadfulTest by tasks.registering(JavaExec::class) { // X11 / XWayland portal parenting e2e: forces GDK onto X11 so Tao windows get // a real XID, then parents a session xdg-desktop-portal FileChooser with // `x11:`.

Oracle ships the G1 static libraries for windows-amd64 and darwin-aarch64 since 25.4; 25.3 advertises --gc=G1 and installs g1GCStructs.h but not g1gc-cr.lib, which makes the build die at link time (LNK1181), so the gate becomes a version floor rather than an OS check. Verified on this machine: Oracle 25.4.4.1.1 windows-x64 builds and the binary reports "Using G1" with -R:MaxRAMPercentage honored; Oracle 25.3.4.1 fails at link; GraalVM CE 25.4 rejects the option outright, which is why the Oracle-only gate stays. --- CLAUDE.md | 2 +- .../application/dsl/GraalvmSettings.kt | 5 +- .../dsl/NativeImageGarbageCollector.kt | 22 ++++++--- .../internal/GraalvmToolchainProvisioner.kt | 18 +++++++ .../internal/configureGraalvmApplication.kt | 1 + .../application/internal/nativeImageGcArgs.kt | 36 ++++++++++++-- .../dsl/NativeImageGarbageCollectorIdsTest.kt | 7 +-- .../internal/GraalvmVersionOfTest.kt | 47 +++++++++++++++++++ .../internal/NativeImageGcArgsTest.kt | 46 ++++++++++++++++-- 9 files changed, 163 insertions(+), 21 deletions(-) create mode 100644 plugin-build/plugin/src/test/kotlin/dev/nucleusframework/desktop/application/internal/GraalvmVersionOfTest.kt diff --git a/CLAUDE.md b/CLAUDE.md index ea27a4312..f693c8bca 100644 --- a/CLAUDE.md +++ b/CLAUDE.md @@ -166,7 +166,7 @@ release. The versions are immutable on Central: never retag, bump the timestamp. - SLF4J is **not** initialized at build time — the API and the app-selected backend both initialize at run time, so the app keeps control of its provider, levels and environment-dependent config. Forcing `--initialize-at-build-time=org.slf4j` from a shared module breaks any run-time-initialized backend (SLF4J 2.x provider discovery parks Logback's `LogbackMDCAdapter`/`LoggerContext` in the image heap → build failure; adding backend classes one by one only exposes the next object). Apps with a fixed backend can opt in via `graalvm { buildArgs.add("--initialize-at-build-time=org.slf4j") }` — it trades a frozen provider and build-machine-captured config for a cheaper first log call. `examples/tao-native-test` bundles Logback + an `MDC` round-trip as the regression fixture - GraalVM task surface mirrors the JVM one: `runGraalvmNative` is the fast dev loop (forces quick-build `-Ob`, ignoring the configured `optimization`), while `createGraalvmNativeDistributable` / `runGraalvmNativeDistributable` / `packageGraalvmNativeDistributionForCurrentOS` build & run the full app folder with the configured optimization (mirror `createDistributable` / `runDistributable` / `packageDistributionForCurrentOS`). Quick vs distributable is detected from the invoked task name and tracked as a compile input, so switching re-compiles - Native images bake a default max heap of 25% of RAM (`-R:MaximumHeapSizePercent=25`, JVM/HotSpot parity) instead of native-image's Serial-GC default of 80%; configurable via `graalvm { maxHeapSizePercent = N }` or an absolute `graalvm { maxHeapSize = "2g" }`, and always overridable at runtime with `-Xmx` -- The image's GC is baked at build time via `graalvm { garbageCollector = NativeImageGarbageCollector.G1 }` (`--gc=`, unset = native-image's Serial GC). `G1` is Oracle GraalVM + Linux only and degrades to a warning plus the Serial GC anywhere else; the baked heap percentage follows the collector (`-R:MaximumHeapSizePercent` for Serial/Epsilon, `-R:MaxRAMPercentage` for G1, which does not know the former) +- The image's GC is baked at build time via `graalvm { garbageCollector = NativeImageGarbageCollector.G1 }` (`--gc=`, unset = native-image's Serial GC). `G1` requires Oracle GraalVM (CE/NIK/Mandrel ship no G1 at all) and, outside Linux, GraalVM **25.4+** — 25.3 advertises `--gc=G1` and ships `g1GCStructs.h` but not `g1gc-cr.lib`, so the build dies at link time; anything unsupported degrades to a warning plus the Serial GC; the baked heap percentage follows the collector (`-R:MaximumHeapSizePercent` for Serial/Epsilon, `-R:MaxRAMPercentage` for G1, which does not know the former) - The GraalVM toolchain is auto-downloaded by default (`graalvm { toolchain { } }` DSL), but only when `graalvm { isEnabled = true }` and only when a native-image task actually runs — every provider is resolved in `doFirst`, so an IDE sync or `gradlew tasks` never pulls a JDK. Cached under `~/.gradle/nucleus/graalvm/`. - **Distribution defaults to GraalVM Community Edition** (`toolchain { distribution }`, GPLv2+CE, resolved from the `graalvm/graalvm-ce-builds` GitHub releases). `GraalvmDistribution.ORACLE` opts into Oracle GraalVM and logs a GFTC licensing warning — the GFTC forbids charging any fee associated with redistributing the Program, and the plugin ships GraalVM runtime libs (`libjvm`, `libawt`, …) next to the executable. In community mode the Oracle-only `runWithPgoInstrument` task is **not registered at all**; `-O3`, `--pgo` and `-H:AdvancedObfuscation` degrade to a warning. `examples/benchmark-demo` opts into ORACLE because `-O3`/PGO are its whole point. - Install dirs embed the distribution (`graalvm-community-jdk-*` vs `graalvm-jdk-*`), so a pre-existing Oracle download is never silently reused after the default flipped; a `GRAALVM_HOME` whose distribution disagrees with the DSL is ignored with a warning.

Date: Thu, 24 Sep 2026 00:32:54 +0300 Subject: [PATCH 178/233] feat(plugin): provision Node.js instead of requiring it, bump electron-builder to 26.16.1 MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Every format but RawAppImage is built by electron-builder, which the plugin installs with `npm ci` against its embedded lock file — so packaging needed a Node.js on the machine, and failed with "node not found" otherwise. The GraalVM JDK and the packaging JDK are already downloaded and cached by the plugin; Node now is too, from nodejs.org, verified against the release's SHASUMS256.txt, into /nucleus/nodejs. Configured with nativeDistributions { nodejs { autoDownload / version / installDir } }. Precedence: the compose.electronBuilder.nodePath property, then NUCLEUS_NODE_HOME, then the provisioned install, then PATH — which is also the fallback when the download fails, so an offline machine with a usable Node still packages. The three provisioners now share ToolchainDownloads (download, checksum, tar) rather than carrying three copies of it. CI drops actions/setup-node and keeps only a cache of the provisioned Node, so the download path is what release and packaging workflows actually exercise. The universal-macos job keeps its own setup-node: build-universal.sh drives electron-builder with npx outside the plugin. --- .github/actions/setup-nucleus/action.yml | 20 +- .github/workflows/release-desktop.yaml | 6 +- .github/workflows/release-graalvm.yaml | 1 - .github/workflows/test-graalvm.yaml | 1 - .github/workflows/test-packaging.yaml | 3 - CLAUDE.md | 1 + .../dsl/JvmApplicationDistributions.kt | 10 + .../desktop/application/dsl/NodeJsSettings.kt | 46 +++ .../internal/GraalvmToolchainProvisioner.kt | 93 +----- .../internal/NodeToolchainProvisioner.kt | 292 ++++++++++++++++++ .../NucleusJdkToolchainProvisioner.kt | 94 +----- .../internal/ToolchainDownloads.kt | 140 +++++++++ .../internal/configureGraalvmApplication.kt | 1 + .../internal/configureJvmApplication.kt | 1 + .../ElectronBuilderToolManager.kt | 2 +- .../AbstractElectronBuilderPackageTask.kt | 83 +++-- .../electron-builder/package-lock.json | 218 ++++++------- .../nucleus/electron-builder/package.json | 2 +- .../internal/NodeToolchainProvisionerTest.kt | 92 ++++++ 19 files changed, 787 insertions(+), 319 deletions(-) create mode 100644 plugin-build/plugin/src/main/kotlin/dev/nucleusframework/desktop/application/dsl/NodeJsSettings.kt create mode 100644 plugin-build/plugin/src/main/kotlin/dev/nucleusframework/desktop/application/internal/NodeToolchainProvisioner.kt create mode 100644 plugin-build/plugin/src/main/kotlin/dev/nucleusframework/desktop/application/internal/ToolchainDownloads.kt create mode 100644 plugin-build/plugin/src/test/kotlin/dev/nucleusframework/desktop/application/internal/NodeToolchainProvisionerTest.kt diff --git a/.github/actions/setup-nucleus/action.yml b/.github/actions/setup-nucleus/action.yml index c91771367..60beda3ef 100644 --- a/.github/actions/setup-nucleus/action.yml +++ b/.github/actions/setup-nucleus/action.yml @@ -38,14 +38,10 @@ inputs: description: 'GraalVM distribution, used only as a cache-key component.

The shim skips the per-bundle pass (`$2` is the `.app`) and execs the app's copy, staged as `nucleus-app-pre` / `nucleus-app-post` — names electron-builder's `name.includes("preinstall")` scan must not match.

It downloads one from `nodejs.org` (verified against the release's `SHASUMS256.txt`) into `/nucleus/nodejs`, exactly like the GraalVM and packaging JDK toolchains, and the three share `ToolchainDownloads`. Configure with `nativeDistributions { nodejs { autoDownload / version / installDir } }`; `version` is a major line (`"22"`, the default), `"lts"`, or a pinned release, and a floating line is sticky once downloaded. Precedence: the `compose.electronBuilder.nodePath` Gradle property, then `NUCLEUS_NODE_HOME`, then the provisioned install, then `PATH` (also the fallback when the download fails). CI therefore runs **no** `actions/setup-node` — only a cache of `~/.gradle/nucleus/nodejs`. The one exception is `release-desktop`'s `universal-macos` job: `build-macos-universal/build-universal.sh` drives electron-builder with `npx` itself, outside the plugin - The HotSpot GC is selected type-safely with `application { garbageCollector = GarbageCollector.Z }` (unset = JVM ergonomics). The flags are prepended to the launcher `.cfg` java-options and to the `run` task — before `jvmArgs`, so an explicit `-XX:+Use…GC` there still wins — and the AOT training run inherits them from the `.cfg` ## Adding a Native JNI Module diff --git a/plugin-build/plugin/src/main/kotlin/dev/nucleusframework/desktop/application/dsl/JvmApplicationDistributions.kt b/plugin-build/plugin/src/main/kotlin/dev/nucleusframework/desktop/application/dsl/JvmApplicationDistributions.kt index 0d9a9ec7f..1acdf1354 100644 --- a/plugin-build/plugin/src/main/kotlin/dev/nucleusframework/desktop/application/dsl/JvmApplicationDistributions.kt +++ b/plugin-build/plugin/src/main/kotlin/dev/nucleusframework/desktop/application/dsl/JvmApplicationDistributions.kt @@ -148,6 +148,16 @@ abstract class JvmApplicationDistributions : AbstractDistributions() { fn.execute(publish) } + // --- Node.js used to run electron-builder --- + + /** Node.js acquisition for the electron-builder pipeline.

App Store PKG = sandboxed pipeline, "3rd Party Mac Developer" certificates, `productsign` after the build, never notarized (Transporter upload). `appStore = false` = Developer ID PKG on the DMG pipeline (#249): electron-builder signs the installer itself from `pkg.identity` = the **bare** `NAME (TEAMID)` (it prepends "Developer ID Installer" and rejects a prefixed qualifier; `CSC_IDENTITY_AUTO_DISCOVERY=false` means no identity ⇒ silently unsigned, which the task catches with `pkgutil --check-signature`), a DSL keychain travels as `CSC_KEYCHAIN`, and `notarizePkg` notarizes the `.pkg`. `pkg { preInstall / postInstall }` are staged in `/build/pkg-scripts` for `pkgbuild --scripts` (shebang required); the App Store rejects install scripts (error 90254), so they require `appStore = false`. **The staged `preinstall` / `postinstall` are Nucleus shims, not the app's script**: electron-builder sets `BundlePre/PostInstallScriptPath` *and* passes `--scripts`, so `PackageInfo` declares each script twice and Installer runs it twice (confirmed on a real install). The shim skips the per-bundle pass (`$2` is the `.app`) and execs the app's copy, staged as `nucleus-app-pre` / `nucleus-app-post` — names electron-builder's `name.includes("preinstall")` scan must not match.

Date: Thu, 24 Sep 2026 07:32:17 +0300 Subject: [PATCH 180/233] feat(tao): report a stalled event loop instead of freezing silently (#643) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit A deadlocked Tao event loop produces no exception, no panic and no error code: to the JVM the thread is a healthy RUNNABLE / _thread_in_native, so the fatal path has nothing to record, and its reporting point sits after nativeRunBlocking — which a stalled loop never leaves. #640 therefore froze the app in complete silence. Ask the OS instead. A min-priority daemon thread polls IsHungAppWindow every 2s and, once a window has been hung past a grace period on top of Windows' own ~5s threshold, logs SEVERE with a full thread dump naming the event-loop thread. The probe is a pure query of state the OS already maintains: it sends nothing to the loop, unlike a SendMessageTimeout(WM_NULL) probe whose inline sent message is the very re-entrancy that deadlocked #640. HWNDs are cached on WINDOW_READY from the loop thread, since resolving one later goes through the native window map whose lock a stalled loop may hold. The app-facing shape follows Electron: onUnresponsive / onResponsive on NucleusApplicationScope and TaoApplication mirror webContents' unresponsive / responsive, and the framework ships no UI of its own — the "wait or quit" prompt is the app's to build, as it is in Chromium's HangWatcher, IntelliJ's PerformanceWatcher and Unreal's FThreadHeartBeat. Both callbacks run on the watchdog thread: the UI thread is the stuck one. Two false-positive sources are handled the way the prior art handles them: the watchdog stays out of debug sessions (a breakpoint on the UI thread is indistinguishable from a stall — the reason Unreal ships HangDuration=0), and a poll that overslept by more than 10s is read as a system suspend, dropping the episode and ignoring the next 30s (Electron #53529). Windows only for now: macOS exposes no public "not responding" query and X11's _NET_WM_PING perturbs the loop it observes. --- CLAUDE.md | 2 +- .../api/decorated-window-tao.api | 2 + decorated-window-tao/build.gradle.kts | 28 ++ .../window/tao/TaoApplication.kt | 71 +++- .../window/tao/TaoEventLoopWatchdog.kt | 337 ++++++++++++++++++ .../nucleusframework/window/tao/TaoWindow.kt | 9 +- .../window/tao/ffi/NativeTaoBridge.kt | 15 + .../main/native/src/platform/windows/mod.rs | 1 + .../native/src/platform/windows/watchdog.rs | 47 +++ .../window/tao/EventLoopHangDetectorTest.kt | 102 ++++++ .../tao/TaoEventLoopWatchdogSmokeTest.kt | 119 +++++++ .../tao/TaoSceneTestBatteryDriftTest.kt | 4 + .../headful/EventLoopWatchdogHeadfulCases.kt | 138 +++++++ .../tao/headful/TaoHeadfulTestSuiteMain.kt | 1 + .../tao/headful/WatchdogDialogSmokeMain.kt | 107 ++++++ .../api/nucleus-application.api | 4 + .../application/NucleusApplicationScope.kt | 31 ++ 17 files changed, 1015 insertions(+), 3 deletions(-) create mode 100644 decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/TaoEventLoopWatchdog.kt create mode 100644 decorated-window-tao/src/main/native/src/platform/windows/watchdog.rs create mode 100644 decorated-window-tao/src/test/kotlin/dev/nucleusframework/window/tao/EventLoopHangDetectorTest.kt create mode 100644 decorated-window-tao/src/test/kotlin/dev/nucleusframework/window/tao/TaoEventLoopWatchdogSmokeTest.kt create mode 100644 decorated-window-tao/src/test/kotlin/dev/nucleusframework/window/tao/headful/EventLoopWatchdogHeadfulCases.kt create mode 100644 decorated-window-tao/src/test/kotlin/dev/nucleusframework/window/tao/headful/WatchdogDialogSmokeMain.kt diff --git a/CLAUDE.md b/CLAUDE.md index f693c8bca..e42afb4e0 100644 --- a/CLAUDE.md +++ b/CLAUDE.md @@ -75,7 +75,7 @@ Published releases are `2.5.x` (latest tag `v2.5.0`).

Everything scroll-related enters the scene through `TaoSceneScrollRouter` (window + NSPanel popups); the phase wire (Rust `SCROLL_GESTURE_*`, `popup_panel.m`, `TaoScrollGesturePhase`) is guarded by `TaoScrollWireDriftTest` - macOS Liquid Glass enabled by default via `macOsSdkVersion = "26.0"` (vtool SDK patching) - **PKG has two channels**, chosen by `macOS { pkg { appStore } }` (default `true`); whether `TargetFormat.Pkg` is a store format is `JvmApplicationDistributions.isSandboxed(format)`, not an enum property. App Store PKG = sandboxed pipeline, "3rd Party Mac Developer" certificates, `productsign` after the build, never notarized (Transporter upload). `appStore = false` = Developer ID PKG on the DMG pipeline (#249): electron-builder signs the installer itself from `pkg.identity` = the **bare** `NAME (TEAMID)` (it prepends "Developer ID Installer" and rejects a prefixed qualifier; `CSC_IDENTITY_AUTO_DISCOVERY=false` means no identity ⇒ silently unsigned, which the task catches with `pkgutil --check-signature`), a DSL keychain travels as `CSC_KEYCHAIN`, and `notarizePkg` notarizes the `.pkg`. `pkg { preInstall / postInstall }` are staged in `/build/pkg-scripts` for `pkgbuild --scripts` (shebang required); the App Store rejects install scripts (error 90254), so they require `appStore = false`. **The staged `preinstall` / `postinstall` are Nucleus shims, not the app's script**: electron-builder sets `BundlePre/PostInstallScriptPath` *and* passes `--scripts`, so `PackageInfo` declares each script twice and Installer runs it twice (confirmed on a real install). The shim skips the per-bundle pass (`$2` is the `.app`) and execs the app's copy, staged as `nucleus-app-pre` / `nucleus-app-post` — names electron-builder's `name.includes("preinstall")` scan must not match. Runtime: gate sandbox-sensitive features on `ExecutableRuntime.isSandboxed()` (`APP_SANDBOX_CONTAINER_ID`), never on `isPkg()` — that is also what makes a Developer ID PKG self-updatable (`NucleusUpdater.isUpdateSupported`) while the App Store build stays excluded diff --git a/decorated-window-tao/api/decorated-window-tao.api b/decorated-window-tao/api/decorated-window-tao.api index 142a2f8c0..032b3201e 100644 --- a/decorated-window-tao/api/decorated-window-tao.api +++ b/decorated-window-tao/api/decorated-window-tao.api @@ -1092,6 +1092,8 @@ public final class dev/nucleusframework/window/tao/TaoApplication { public static final field INSTANCE Ldev/nucleusframework/window/tao/TaoApplication; public final fun exit ()V public final fun isQuitting ()Z + public final fun onResponsive (Lkotlin/jvm/functions/Function0;)V + public final fun onUnresponsive (Lkotlin/jvm/functions/Function0;)V public final fun openWindow (Ljava/lang/String;DDZZZZLdev/nucleusframework/window/tao/TaoWindow;ZZZZ)Ldev/nucleusframework/window/tao/TaoWindow; public static synthetic fun openWindow$default (Ldev/nucleusframework/window/tao/TaoApplication;Ljava/lang/String;DDZZZZLdev/nucleusframework/window/tao/TaoWindow;ZZZZILjava/lang/Object;)Ldev/nucleusframework/window/tao/TaoWindow; public final fun run (Lkotlin/jvm/functions/Function1;)V diff --git a/decorated-window-tao/build.gradle.kts b/decorated-window-tao/build.gradle.kts index 6e453d3e0..669bbba5b 100644 --- a/decorated-window-tao/build.gradle.kts +++ b/decorated-window-tao/build.gradle.kts @@ -331,6 +331,34 @@ val taoFatalDialogSmoke = tasks.register("taoFatalDialogSmoke") { } } +// Smoke for #643: freezes the event loop for real and prints a one-line +// verdict ("severe=1 unresponsive=1 responsive=1"), so every watchdog switch +// can be checked from outside the process — and so the native +// "Application Not Responding" dialog can be looked at.

It now waits on a condition until a window registers, which is what Chromium's HangWatcher does while its watch list is empty. An untimed park says nothing about elapsed time, so it must not feed the suspend heuristic — a parked wake re-baselines the clock and samples on the next tick instead.

Do not treat `IDEAL_API.md - **KDoc on public API**: `UndocumentedPublicClass` / `UndocumentedPublicFunction` are enforced by detekt (`detekt` is wired into `check` / `preMerge`). Pre-existing gaps are grandfathered in per-module `/detekt-baseline.xml` files — any *new* undocumented public class or function fails the build. Do not regenerate a baseline to silence a new finding; write the KDoc. `UndocumentedPublicProperty` stays off because the generated icon/symbol catalogs (`sf-symbols`, `freedesktop-icons`) would swamp it - **Logging**: `java.util.logging` is the single facade for every runtime module — no SLF4J dependency forced on consumers, no raw `println` / `System.err` in `src/main`. Logger names must be the fully-qualified class name (or an explicit `dev.nucleusframework.*` string) so the whole framework sits under one JUL namespace. `allowNucleusRuntimeLogging = true` is an opt-in convenience that raises the `dev.nucleusframework` logger to `nucleusLoggingLevel` and attaches a colored console handler; apps that configure JUL themselves (`logging.properties`, `jul-to-slf4j`) leave it `false` and Nucleus never touches the JUL configuration - `decorated-window-tao` is the only window backend (no AWT, native event-loop-driven, true Windows fullscreen, GraalVM native-image first-class). The AWT-based backends (`decorated-window-awt` / `-jbr` / `-jni`), `NucleusBackend`, `LocalNucleusBackend`, the `backend =` parameter of `nucleusApplication`, and `NucleusWindowUnsafe.awtWindow` / `awtDialog` were all removed in 2.6.

The probe is a pure OS-state query — it sends nothing to the loop, unlike a `SendMessageTimeout(WM_NULL)` probe, whose inline sent message is exactly the re-entrancy that deadlocked #640. HWNDs are cached on `WINDOW_READY` from the event-loop thread: resolving one later goes through the native `WINDOWS` map, whose lock a stalled loop may hold. **The app-facing shape is Electron's**: the framework logs and raises `onUnresponsive` / `onResponsive` (`NucleusApplicationScope`, `TaoApplication` — `webContents`' `unresponsive` / `responsive`), and ships **no UI of its own**; the "wait or quit" prompt is the app's to build, as it is in Electron, Chromium's HangWatcher, IntelliJ's PerformanceWatcher and Unreal's `FThreadHeartBeat`. Both callbacks run **on the watchdog thread** — the UI thread is the stuck one, so anything posted to `Dispatchers.Main` would only run once the stall ends. Off by default under a debug agent (a breakpoint on the UI thread is indistinguishable from a stall — the reason Unreal ships `HangDuration=0`); a poll that overslept by >10 s is read as a system suspend, which drops the episode and ignores the next 30 s (Electron #53529's `base::PowerMonitor` rule). `-Dnucleus.tao.watchdog=false` disables it (`=true` forces it on under a debugger), `-Dnucleus.tao.watchdogGraceMs=` retunes it, `-Dnucleus.tao.watchdogDialog=true` also pops the native dialog (from the watchdog thread — the loop thread is the stuck one, #622's constraint; `nucleus.tao.fatalErrorDialog=false` suppresses it too, as it does every native modal).

Trackpad gestures reach Compose as `PanStart` / `PanMove` / `PanEnd` (`panOffset` = AWT delta × 10 dp), wheel notches as `Scroll`; foundation's `Modifier.scrollable` handles both. Custom handlers that only listen for `PointerEventType.Scroll` must also handle Pan, or the app can set `-Dnucleus.tao.trackpadPanEvents=false` to get AWT-style `Scroll` for everything. Everything scroll-related enters the scene through `TaoSceneScrollRouter` (window + NSPanel popups); the phase wire (Rust `SCROLL_GESTURE_*`, `popup_panel.m`, `TaoScrollGesturePhase`) is guarded by `TaoScrollWireDriftTest` - macOS Liquid Glass enabled by default via `macOsSdkVersion = "26.0"` (vtool SDK patching) - **PKG has two channels**, chosen by `macOS { pkg { appStore } }` (default `true`); whether `TargetFormat.Pkg` is a store format is `JvmApplicationDistributions.isSandboxed(format)`, not an enum property. App Store PKG = sandboxed pipeline, "3rd Party Mac Developer" certificates, `productsign` after the build, never notarized (Transporter upload). `appStore = false` = Developer ID PKG on the DMG pipeline (#249): electron-builder signs the installer itself from `pkg.identity` = the **bare** `NAME (TEAMID)` (it prepends "Developer ID Installer" and rejects a prefixed qualifier; `CSC_IDENTITY_AUTO_DISCOVERY=false` means no identity ⇒ silently unsigned, which the task catches with `pkgutil --check-signature`), a DSL keychain travels as `CSC_KEYCHAIN`, and `notarizePkg` notarizes the `.pkg`. `pkg { preInstall / postInstall }` are staged in `/build/pkg-scripts` for `pkgbuild --scripts` (shebang required); the App Store rejects install scripts (error 90254), so they require `appStore = false`. **The staged `preinstall` / `postinstall` are Nucleus shims, not the app's script**: electron-builder sets `BundlePre/PostInstallScriptPath` *and* passes `--scripts`, so `PackageInfo` declares each script twice and Installer runs it twice (confirmed on a real install). The shim skips the per-bundle pass (`$2` is the `.app`) and execs the app's copy, staged as `nucleus-app-pre` / `nucleus-app-post` — names electron-builder's `name.includes("preinstall")` scan must not match.

GC time over the wait is now corroborated before classifying an overshoot as a resume. - stop() clears the HWND cache even when watch() self-terminated (debug agent, interrupt), so a second run() does not inherit the first run's handles — recycled by Windows, and a non-empty map would also defeat the parking. - registerWindow returns early unless the watchdog is running: a disabled watchdog now costs the event loop nothing per window, instead of a JNI round-trip and a signal for a feature that is off. - The headful case waits for the callback as well as the log line; the log is emitted before the app is told, so the assertion raced the event thread. --- .../window/tao/TaoEventLoopWatchdog.kt | 76 ++++++++++++++++--- .../headful/EventLoopWatchdogHeadfulCases.kt | 8 +- 2 files changed, 73 insertions(+), 11 deletions(-) diff --git a/decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/TaoEventLoopWatchdog.kt b/decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/TaoEventLoopWatchdog.kt index 9756db00b..a8c9968d8 100644 --- a/decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/TaoEventLoopWatchdog.kt +++ b/decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/TaoEventLoopWatchdog.kt @@ -5,6 +5,8 @@ import dev.nucleusframework.window.tao.dispatch.TaoMainDispatcher import dev.nucleusframework.window.tao.ffi.NativeTaoBridge import java.lang.management.ManagementFactory import java.util.concurrent.ConcurrentHashMap +import java.util.concurrent.ExecutorService +import java.util.concurrent.Executors import java.util.concurrent.TimeUnit import java.util.concurrent.atomic.AtomicBoolean import java.util.concurrent.atomic.AtomicInteger @@ -27,6 +29,9 @@ private const val SUSPEND_OVERSHOOT_MS = 10_000L /** How long samples are ignored after a resume — Electron's `kHungRendererDelay` rule. */ private const val RESUME_GRACE_MS = 30_000L +/** An overshoot is a GC pause when collection explains more than this fraction of it. */ +private const val GC_PAUSE_SHARE_DIVISOR = 2 + /** * Watches the Tao event loop and reports a stall instead of letting the app * freeze silently (#643). @@ -93,6 +98,10 @@ internal object TaoEventLoopWatchdog { @Volatile private var thread: Thread? = null + /** Runs the app's `unresponsive` / `responsive` callbacks; see [postEvent]. */ + @Volatile + private var eventExecutor: ExecutorService? = null + /** `true` on a platform that has a non-perturbing liveness probe. */ private val isSupported: Boolean get() = Platform.Current == Platform.Windows && NativeTaoBridge.isLoaded @@ -136,7 +145,10 @@ internal object TaoEventLoopWatchdog { * thread once the window is realized (`WINDOW_READY`). */ fun registerWindow(handle: Long) { - if (!isSupported) return + // `running` covers every off state — unsupported platform, the + // property, a debug agent, a stopped loop.

Thread.getAllStackTraces() can fail on a large heap, JUL propagates a throwing Handler.publish (apps attach handlers, and so do our own tests), and the event executor can refuse a task — any of which killed the watchdog thread with `running` still true, unrevivable and silent. That is the failure mode this class exists to remove; it must not be its own instance of it. - A watch list that drains mid-stall closes the episode before parking. The user closing the frozen window would otherwise leave the app's prompt and telemetry span open with no `responsive` ever coming. - start() resets the expected-stall depth and stop() shuts the event executor down, so a second run() in the same process is genuinely a fresh start. A scope whose `finally` never ran left the next run permanently disarmed. - The KDoc named the wrong thread: callbacks run on nucleus-tao-watchdog-events, not the watchdog thread — which is the whole point of the executor, since a blocking listener must not stop the sampling. --- CLAUDE.md | 2 +- .../window/tao/TaoApplication.kt | 14 +++-- .../window/tao/TaoEventLoopWatchdog.kt | 55 ++++++++++++++++++- .../application/NucleusApplicationScope.kt | 8 ++- 4 files changed, 66 insertions(+), 13 deletions(-) diff --git a/CLAUDE.md b/CLAUDE.md index ac4987bfe..1e1402aa6 100644 --- a/CLAUDE.md +++ b/CLAUDE.md @@ -75,7 +75,7 @@ Published releases are `2.5.x` (latest tag `v2.5.0`).

Logger names must be the fully-qualified class name (or an explicit `dev.nucleusframework.*` string) so the whole framework sits under one JUL namespace. `allowNucleusRuntimeLogging = true` is an opt-in convenience that raises the `dev.nucleusframework` logger to `nucleusLoggingLevel` and attaches a colored console handler; apps that configure JUL themselves (`logging.properties`, `jul-to-slf4j`) leave it `false` and Nucleus never touches the JUL configuration - `decorated-window-tao` is the only window backend (no AWT, native event-loop-driven, true Windows fullscreen, GraalVM native-image first-class). The AWT-based backends (`decorated-window-awt` / `-jbr` / `-jni`), `NucleusBackend`, `LocalNucleusBackend`, the `backend =` parameter of `nucleusApplication`, and `NucleusWindowUnsafe.awtWindow` / `awtDialog` were all removed in 2.6. Compose Desktop's AWT `Window` / `Dialog` / `Tray` are unsupported — use `DecoratedWindow`, `HostedWindow` / `HostedDialog`, and an AWT-free tray -- **Event-loop watchdog** (#643): a stalled loop produces no exception — to the JVM the thread is a healthy `RUNNABLE` / `_thread_in_native` — and `TaoApplication.rethrowPendingFatal` sits *after* `nativeRunBlocking`, which a deadlocked loop never leaves, so #640 froze silently. `TaoEventLoopWatchdog` is a min-priority daemon thread that polls `IsHungAppWindow` (`NativeTaoBridge.nativeIsWindowHung`) every 2 s and logs `SEVERE` + a full thread dump once a window has been hung past the grace period on top of Windows' own ~5 s threshold. The probe is a pure OS-state query — it sends nothing to the loop, unlike a `SendMessageTimeout(WM_NULL)` probe, whose inline sent message is exactly the re-entrancy that deadlocked #640.

Both callbacks run **on the watchdog thread** — the UI thread is the stuck one, so anything posted to `Dispatchers.Main` would only run once the stall ends. Off by default under a debug agent (a breakpoint on the UI thread is indistinguishable from a stall — the reason Unreal ships `HangDuration=0`); a poll that overslept by >10 s is read as a system suspend, which drops the episode and ignores the next 30 s (Electron #53529's `base::PowerMonitor` rule). `expectUnresponsive { }` (`NucleusApplicationScope`, `TaoApplication`) declares a long synchronous operation so it is not reported — Chromium's `InvalidateActiveExpectations()`, and the reason the global switch is not the only recourse. The watchdog thread parks while no window is registered (HangWatcher does the same with an empty watch list). `-Dnucleus.tao.watchdog=false` disables it (`=true` forces it on under a debugger), `-Dnucleus.tao.watchdogGraceMs=` retunes it, `-Dnucleus.tao.watchdogDialog=true` also pops the native dialog (from the watchdog thread — the loop thread is the stuck one, #622's constraint; `nucleus.tao.fatalErrorDialog=false` suppresses it too, as it does every native modal).

Custom handlers that only listen for `PointerEventType.Scroll` must also handle Pan, or the app can set `-Dnucleus.tao.trackpadPanEvents=false` to get AWT-style `Scroll` for everything. Everything scroll-related enters the scene through `TaoSceneScrollRouter` (window + NSPanel popups); the phase wire (Rust `SCROLL_GESTURE_*`, `popup_panel.m`, `TaoScrollGesturePhase`) is guarded by `TaoScrollWireDriftTest` - macOS Liquid Glass enabled by default via `macOsSdkVersion = "26.0"` (vtool SDK patching) - **PKG has two channels**, chosen by `macOS { pkg { appStore } }` (default `true`); whether `TargetFormat.Pkg` is a store format is `JvmApplicationDistributions.isSandboxed(format)`, not an enum property. App Store PKG = sandboxed pipeline, "3rd Party Mac Developer" certificates, `productsign` after the build, never notarized (Transporter upload). `appStore = false` = Developer ID PKG on the DMG pipeline (#249): electron-builder signs the installer itself from `pkg.identity` = the **bare** `NAME (TEAMID)` (it prepends "Developer ID Installer" and rejects a prefixed qualifier; `CSC_IDENTITY_AUTO_DISCOVERY=false` means no identity ⇒ silently unsigned, which the task catches with `pkgutil --check-signature`), a DSL keychain travels as `CSC_KEYCHAIN`, and `notarizePkg` notarizes the `.pkg`. `pkg { preInstall / postInstall }` are staged in `/build/pkg-scripts` for `pkgbuild --scripts` (shebang required); the App Store rejects install scripts (error 90254), so they require `appStore = false`. **The staged `preinstall` / `postinstall` are Nucleus shims, not the app's script**: electron-builder sets `BundlePre/PostInstallScriptPath` *and* passes `--scripts`, so `PackageInfo` declares each script twice and Installer runs it twice (confirmed on a real install).

A thread now touches shared state only while it owns the current generation. - The drain-before-parking call went through the same guard as the rest. It logs and posts, so a throwing JUL handler or an executor stop() had just shut down killed the thread on the one path that was left unprotected. - The event executor is created and replaced under the lock, with a stopped flag. A plain read-create-assign racing stop() either resurrected an executor nobody would shut down, or pushed onto one already gone. - stop() drains the detector before tearing down, so a stall still open when the loop exits gets its onResponsive.

Date: Thu, 24 Sep 2026 09:49:34 +0300 Subject: [PATCH 190/233] test(tao): concurrency monkey for the watchdog, and the bug it found MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The four review passes found five lifecycle races by reading. This finds them by playing: worker threads hammer start / stop / registerWindow / expectUnresponsive / probe flips at once, against a fake probe and a sub-millisecond poll (WatchdogTestHooks), across five profiles — Balanced, Thrash (lifecycle only), Flapping (the probe flips constantly), Hostile (everything throws, and the callbacks call back in) and Interrupted (a shutdown hook sweeping threads by name). -Dnucleus.tao.watchdogMonkeySeeds=N sweeps N seeds in one JVM; a failure prints the profile, the seed and the last actions. Invariants: the storm terminates (a join timeout dumps every stack — the deadlock detector), nothing escapes the watchdog's surface, every unresponsive is paired with a responsive, no watchdog thread is left alive, and the watchdog still reports afterwards. Its first run found a real one: report() logged before notifying, so a throwing JUL Handler.publish — apps install handlers, and so do these tests — skipped the app notification while the detector had already marked the stall reported. The app then got a `responsive` for a stall it was never told about. Diagnostics must not outrank the contract: the app hears first, and the log is guarded. --- .../window/tao/TaoEventLoopWatchdog.kt | 74 ++- .../tao/TaoEventLoopWatchdogMonkeyTest.kt | 497 ++++++++++++++++++ .../tao/TaoSceneTestBatteryDriftTest.kt | 2 + 3 files changed, 562 insertions(+), 11 deletions(-) create mode 100644 decorated-window-tao/src/test/kotlin/dev/nucleusframework/window/tao/TaoEventLoopWatchdogMonkeyTest.kt diff --git a/decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/TaoEventLoopWatchdog.kt b/decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/TaoEventLoopWatchdog.kt index 4aab384b3..9569ceca6 100644 --- a/decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/TaoEventLoopWatchdog.kt +++ b/decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/TaoEventLoopWatchdog.kt @@ -79,6 +79,31 @@ private const val GC_PAUSE_SHARE_DIVISOR = 2 * the X11 `_NET_WM_PING` equivalent perturbs the loop it observes — which the * probe must not do.

Date: Thu, 24 Sep 2026 10:15:36 +0300 Subject: [PATCH 191/233] fix(tao): two watchdog leaks the concurrency monkey found MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Both surfaced only under a storm, and both are the same mistake twice: state shared between runs has to be raced against, state owned by a thread does not. - The detector is the sampling thread's own, and every exit path drains it. It was shared, so an interrupted watchdog (a shutdown hook sweeping threads by name) left a reported stall behind, and the next start() replaced the detector with it — the app's `unresponsive` never got its `responsive`. Torture/23757 caught it after 809 episodes, Thrash/467221 after 261. - The park re-checks `running` and its generation under the lock it is signalled with, and is bounded at 30s. A thread that decided to park an instant after the last signalAll waited for a signal that never came: the monkey ended a sweep with 150 live watchdog threads, one leaked per run. - The callback executor is process-wide and never shut down. Tearing it down per run meant racing its teardown and dropping the callback that closes an episode; a daemon thread parked on an empty queue costs nothing. The monkey gains the Torture profile (16 threads, nothing sleeps), a callback-thread accumulation check, stack dumps for leaked threads, and -Dnucleus.tao.watchdogMonkeySeeds=N to sweep hundreds of storms in one JVM — which is how all three were found. The Gradle test task now forwards those properties and tracks them as inputs; without that a sweep silently re-ran the default seeds and reported the previous verdict. --- decorated-window-tao/build.gradle.kts | 17 ++ .../window/tao/TaoEventLoopWatchdog.kt | 151 ++++++++++-------- .../tao/TaoEventLoopWatchdogMonkeyTest.kt | 42 ++++- 3 files changed, 139 insertions(+), 71 deletions(-) diff --git a/decorated-window-tao/build.gradle.kts b/decorated-window-tao/build.gradle.kts index 60066c925..1aa853f61 100644 --- a/decorated-window-tao/build.gradle.kts +++ b/decorated-window-tao/build.gradle.kts @@ -81,6 +81,23 @@ nucleusNative { linux("nucleus_tao", "Compiles the Rust JNI bridge + EGL helper into Linux .so libraries") } +// The watchdog concurrency monkey's knobs, forwarded into the test JVM — a +// Gradle `-D` does not reach it otherwise, so a seed sweep would silently run +// the defaults.

It checks what only a running app can answer: after every freeze, withFrameNanos must tick again. A watchdog that perturbed the loop would show up as frames that never resume, and no unit test can see that. Both headful monkeys now wait for each long freeze's report before moving on. Counting them at the end made the suite flaky: a report landing during the next move read as "a short freeze was reported" (seeds 31337 and 20260924, red in a batch and green alone — which is how a flake announces itself).

Skiko was the only library already shipped loose. jpackage pipeline: the target platform's nucleus/native/-/ entries move out of every JAR into $APPDIR, the other platforms' copies are dropped, and the launcher gets -Dnucleus.native.libraryPath=$APPDIR, which the loader now tries first. The plugin only does it when core-runtime's META-INF/nucleus/bundled-native-libraries marker is on the classpath, since an older loader would not look there; the sandboxed pipeline keeps its own layout. GraalVM pipeline: the image is compiled from a copy of the uber JAR without nucleus/native/**, so the nucleus/** resource glob embeds none of them, and the libraries are copied next to the executable, where GraalVmInitializer's java.library.path already resolves them (macOS: Contents/MacOS, stripped, patched and signed with the other dylibs).

The versions are immutable on Central: never retag, bump the timestamp. - GraalVM Deb/Rpm/Pacman packages honor `linux { afterInstall / afterRemove / beforeInstall / beforeRemove }` the same as JVM jpackage/electron-builder. User scripts are concatenated after Nucleus templates. electron-builder substitutes `${sanitizedProductName}` and `${executable}` only when those tokens are single-quoted (`'${sanitizedProductName}-daemon.service'`); double-quoted `"${sanitizedProductName}"` is left unsubstituted and systemd hooks silently no-op. Pacman `.INSTALL` `pre_remove` does not get deb-style `$1=upgrade`, so stop/disable the unit unconditionally and let after-install re-enable on upgrade. - `graalvm { headless = true }` is for daemons/CLIs: skips L3 AWT/Java2D platform metadata, skips always-on L1 packs (`jdk-awt`, `jdk-fonts`, `jdk-graphics2d`, Skiko/Compose/tray), skips copying companion GUI native libs (`libawt`, `libfontmanager`, Skiko, …), and bakes `-Djava.awt.headless=true`. Default `false` (GUI). Without this, JNI registration of AWT types makes `native-image` pull `libawt`/`libawt_xawt` even when app code never references `java.awt`. - `graalvm-runtime` auto-includes `.svg`, `.ttf`, `.otf`, `composeResources/*`, `nucleus/native/*`, and `META-INF/services/*` via `reachability-metadata.json` resource globs (the deprecated `-H:IncludeResources` option was dropped). The blanket `**/*.{svg,ttf,otf}` globs are a required catch-all for fonts/icons bundled inside **library** JARs (e.g. Jewel SVG icons) — those are not the app's own resources so `autoIncludeResources` doesn't cover them. They knowingly trigger native-image's advisory "pattern too generic" warning; do not remove them (it breaks Jewel icons in native image) +- **Nucleus JNI libraries ship loose, never extracted at run time**, in both pipelines. jpackage (`AbstractJPackageTask.prepareWorkingDir`): the target platform's `nucleus/native/-/*` move out of every JAR into `$APPDIR` next to Skiko, other platforms' copies are dropped, and the launcher gets `-Dnucleus.native.libraryPath=$APPDIR`, which `NativeLibraryLoader` tries first — only when `core-runtime`'s `META-INF/nucleus/bundled-native-libraries` marker is on the classpath (an older loader would not look there, so the libs stay in the JARs), and never in the sandboxed pipeline, which has its own layout. GraalVM: `unpackGraalvmNucleusNatives` compiles the image from a copy of the uber JAR without `nucleus/native/**` (so the `nucleus/**` glob embeds none) and `copyGraalvmNucleusNatives` puts the libs next to the executable, where `GraalVmInitializer`'s `java.library.path` resolves them (macOS: `Contents/MacOS`, stripped/patched/signed with the other dylibs). Measured on Windows (`tao-demo`, 9 DLLs): extraction cost ~40–90 ms on the first launch after an install or update, the warm-cache path ~10 ms - The tracing agent (`runWithNativeAgent`) is only needed for app-specific reflection, uncommon libraries, and resource bundles - PGO (Oracle GraalVM): `runWithPgoInstrument` builds + runs an instrumented image and records `graalvm/pgo/default.iprof` on exit; later native-image builds apply the profile automatically. Opt out with `-Pnucleus.graalvm.pgo=off`; customize via `graalvm { pgo { enabled / profile } }` - Agent output is automatically deduplicated against library metadata on the classpath diff --git a/core-runtime/src/main/kotlin/dev/nucleusframework/core/runtime/NativeLibraryLoader.kt b/core-runtime/src/main/kotlin/dev/nucleusframework/core/runtime/NativeLibraryLoader.kt index bf4771934..bbf3244ab 100644 --- a/core-runtime/src/main/kotlin/dev/nucleusframework/core/runtime/NativeLibraryLoader.kt +++ b/core-runtime/src/main/kotlin/dev/nucleusframework/core/runtime/NativeLibraryLoader.kt @@ -3,6 +3,7 @@ package dev.nucleusframework.core.runtime import java.net.JarURLConnection import java.net.URL import java.nio.file.Files +import java.nio.file.InvalidPathException import java.nio.file.Path import java.nio.file.StandardCopyOption import java.util.logging.Level @@ -35,9 +36,11 @@ import java.util.logging.Logger * directory that cannot be created or written to is logged and replaced by * the platform default rather than failing the load. * - * Packaged applications built by the Nucleus Gradle plugin ship their native - * libraries on `java.library.path` and never extract anything; this setting - * only matters for fat JARs, IDE runs and distributions that bypass the plugin. + * Packaged applications built by the Nucleus Gradle plugin never extract + * anything: the plugin moves the libraries out of the JARs into the directory + * named by the `nucleus.native.libraryPath` system property (sandboxed store + * builds put them on `java.library.path` instead).

Both now poll. - The animating monkey twice found frames that never resumed after a long freeze, on a loop that was demonstrably pumping (the test's own delay ran). Both seeds pass in isolation, so it is intermittent. Rather than weaken the assertion, the case now diagnoses it: on a stall it asks the window for one frame and says whether that unstuck it — a lost invalidation and a dead frame clock are different bugs, and neither would belong to the watchdog. --- .../tao/TaoEventLoopWatchdogMonkeyTest.kt | 13 +++++++++--- .../EventLoopWatchdogAnimationHeadfulCases.kt | 21 +++++++++++++------ .../EventLoopWatchdogMonkeyHeadfulCases.kt | 15 +++++++++++-- 3 files changed, 38 insertions(+), 11 deletions(-) diff --git a/decorated-window-tao/src/test/kotlin/dev/nucleusframework/window/tao/TaoEventLoopWatchdogMonkeyTest.kt b/decorated-window-tao/src/test/kotlin/dev/nucleusframework/window/tao/TaoEventLoopWatchdogMonkeyTest.kt index 79d32f680..db586f039 100644 --- a/decorated-window-tao/src/test/kotlin/dev/nucleusframework/window/tao/TaoEventLoopWatchdogMonkeyTest.kt +++ b/decorated-window-tao/src/test/kotlin/dev/nucleusframework/window/tao/TaoEventLoopWatchdogMonkeyTest.kt @@ -192,9 +192,15 @@ class TaoEventLoopWatchdogMonkeyTest { // `unresponsive` must always hear the end of the episode. if (ctx.unresponsive.get() != ctx.responsive.get()) bail("unresponsive/responsive left unpaired") - // 4 — nothing left behind: neither the sampler nor the callback thread - // the run created for itself.

When the OS swallows that event instead, the latch suppresses every later request and the window silently stops painting — an app with a live event loop and a dead picture, which reads to the user as "frozen until I click on it again". The code already patched two ways that happens: resetRedrawLatch() for a nested modal pump, and the FOCUSED branch for an occluding modal child. The #643 monkeys found a third — an app frozen long enough for Windows to ghost its window came back pumping but never painted again, twice across a night sweep, on a loop the test could prove was alive because its own delay() was running. Rather than enumerate the ways an invalidation can be lost, treat a request the OS has not answered within a second as lost and ask again: at most one extra, idempotent request per second, and no frame is lost either way. The constant is file-level private on purpose — a const val in the private companion would land on the validated ABI, as that companion warns two constants above.

The jpackage and GraalVM pipelines move exactly the union of those entries.

The versions are immutable on Central: never retag, bump the timestamp. - GraalVM Deb/Rpm/Pacman packages honor `linux { afterInstall / afterRemove / beforeInstall / beforeRemove }` the same as JVM jpackage/electron-builder. User scripts are concatenated after Nucleus templates. electron-builder substitutes `${sanitizedProductName}` and `${executable}` only when those tokens are single-quoted (`'${sanitizedProductName}-daemon.service'`); double-quoted `"${sanitizedProductName}"` is left unsubstituted and systemd hooks silently no-op. Pacman `.INSTALL` `pre_remove` does not get deb-style `$1=upgrade`, so stop/disable the unit unconditionally and let after-install re-enable on upgrade. - `graalvm { headless = true }` is for daemons/CLIs: skips L3 AWT/Java2D platform metadata, skips always-on L1 packs (`jdk-awt`, `jdk-fonts`, `jdk-graphics2d`, Skiko/Compose/tray), skips copying companion GUI native libs (`libawt`, `libfontmanager`, Skiko, …), and bakes `-Djava.awt.headless=true`. Default `false` (GUI). Without this, JNI registration of AWT types makes `native-image` pull `libawt`/`libawt_xawt` even when app code never references `java.awt`. - `graalvm-runtime` auto-includes `.svg`, `.ttf`, `.otf`, `composeResources/*`, `nucleus/native/*`, and `META-INF/services/*` via `reachability-metadata.json` resource globs (the deprecated `-H:IncludeResources` option was dropped). The blanket `**/*.{svg,ttf,otf}` globs are a required catch-all for fonts/icons bundled inside **library** JARs (e.g. Jewel SVG icons) — those are not the app's own resources so `autoIncludeResources` doesn't cover them. They knowingly trigger native-image's advisory "pattern too generic" warning; do not remove them (it breaks Jewel icons in native image) -- **Nucleus JNI libraries ship loose, never extracted at run time**, in both pipelines. jpackage (`AbstractJPackageTask.prepareWorkingDir`): the target platform's `nucleus/native/-/*` move out of every JAR into `$APPDIR` next to Skiko, other platforms' copies are dropped, and the launcher gets `-Dnucleus.native.libraryPath=$APPDIR`, which `NativeLibraryLoader` tries first — only when `core-runtime`'s `META-INF/nucleus/bundled-native-libraries` marker is on the classpath (an older loader would not look there, so the libs stay in the JARs), and never in the sandboxed pipeline, which has its own layout. GraalVM: `unpackGraalvmNucleusNatives` compiles the image from a copy of the uber JAR without `nucleus/native/**` (so the `nucleus/**` glob embeds none) and `copyGraalvmNucleusNatives` puts the libs next to the executable, where `GraalVmInitializer`'s `java.library.path` resolves them (macOS: `Contents/MacOS`, stripped/patched/signed with the other dylibs). Measured on Windows (`tao-demo`, 9 DLLs): extraction cost ~40–90 ms on the first launch after an install or update, the warm-cache path ~10 ms +- **Nucleus JNI libraries ship loose, never extracted at run time**, in both pipelines. Only **Nucleus** libraries move: every `nucleus.native-module` module ships `META-INF/nucleus/native-libraries/nucleus.` (generated by `generateNativeLibrariesManifest`, one `nucleus/native//` entry per line, sidecars included, plus the dependency libraries it declares with `nucleusNative { dependencyLibraries(NativeTarget.WINDOWS, "libEGL.dll", "libGLESv2.dll") }` — ANGLE lives in the external `nucleus.angle-natives` JAR), and the plugin moves exactly the union of those entries across the classpath; every other entry under `nucleus/native/` (an app's own dylib read through `getResourceAsStream`, as `tao-demo`'s SwiftUI bridge does, or a third-party library such as `composewebview`) stays in its JAR untouched. jpackage (`AbstractJPackageTask.prepareWorkingDir`): the target platform's listed libraries move into `$APPDIR` next to Skiko, other platforms' listed copies are dropped, and the launcher gets `-Dnucleus.native.libraryPath=$APPDIR`, which `NativeLibraryLoader` tries first — only when `core-runtime`'s `META-INF/nucleus/bundled-native-libraries` marker is on the classpath (an older loader would not look there, so the libs stay in the JARs), and never in the sandboxed pipeline, which has its own layout.

It left three log calls bare, and one of them sits on the interrupt path — between the stall a thread has just reported and the drain that closes it. A handler that throws there kills the thread before the drain, and the app's `unresponsive` never gets its `responsive`: a "wait or quit" prompt or a telemetry span left open for good. Found by elimination over ~1.4M events, each step measured rather than reasoned: the extended wait ruled out lateness, the produced-vs-delivered counters ruled out the callback path, the stack dump ruled out a blocked thread, the selective trace showed the thread dying between the stall and any exit, and bracketing the report narrowed it to the one statement after it. The heisenbug that hid it — green under heavy tracing — was the interrupt no longer landing in that window. The monkey keeps the instrumentation that found it: transition counters, a selective trace of episodes and exits, and the stacks of surviving threads. --- .../window/tao/TaoEventLoopWatchdog.kt | 70 +++++++++++++++++-- .../tao/TaoEventLoopWatchdogMonkeyTest.kt | 18 ++++- 2 files changed, 82 insertions(+), 6 deletions(-) diff --git a/decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/TaoEventLoopWatchdog.kt b/decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/TaoEventLoopWatchdog.kt index f89c48945..c61f946a3 100644 --- a/decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/TaoEventLoopWatchdog.kt +++ b/decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/TaoEventLoopWatchdog.kt @@ -5,6 +5,7 @@ import dev.nucleusframework.window.tao.dispatch.TaoMainDispatcher import dev.nucleusframework.window.tao.ffi.NativeTaoBridge import java.lang.management.ManagementFactory import java.util.concurrent.ConcurrentHashMap +import java.util.concurrent.ConcurrentLinkedDeque import java.util.concurrent.ExecutorService import java.util.concurrent.Executors import java.util.concurrent.TimeUnit @@ -53,10 +54,37 @@ internal object WatchdogTestHooks { @Volatile var pollIntervalMs: Long? = null + /** + * Transitions the watchdog *produced*, as opposed to callbacks the app + * *received*.

Do not treat `IDEAL_API.md - **Logging**: `java.util.logging` is the single facade for every runtime module — no SLF4J dependency forced on consumers, no raw `println` / `System.err` in `src/main`. Logger names must be the fully-qualified class name (or an explicit `dev.nucleusframework.*` string) so the whole framework sits under one JUL namespace. `allowNucleusRuntimeLogging = true` is an opt-in convenience that raises the `dev.nucleusframework` logger to `nucleusLoggingLevel` and attaches a colored console handler; apps that configure JUL themselves (`logging.properties`, `jul-to-slf4j`) leave it `false` and Nucleus never touches the JUL configuration - `decorated-window-tao` is the only window backend (no AWT, native event-loop-driven, true Windows fullscreen, GraalVM native-image first-class). The AWT-based backends (`decorated-window-awt` / `-jbr` / `-jni`), `NucleusBackend`, `LocalNucleusBackend`, the `backend =` parameter of `nucleusApplication`, and `NucleusWindowUnsafe.awtWindow` / `awtDialog` were all removed in 2.6. Compose Desktop's AWT `Window` / `Dialog` / `Tray` are unsupported — use `DecoratedWindow`, `HostedWindow` / `HostedDialog`, and an AWT-free tray - **Event-loop watchdog** (#643): a stalled loop produces no exception — to the JVM the thread is a healthy `RUNNABLE` / `_thread_in_native` — and `TaoApplication.rethrowPendingFatal` sits *after* `nativeRunBlocking`, which a deadlocked loop never leaves, so #640 froze silently. `TaoEventLoopWatchdog` is a min-priority daemon thread that polls `IsHungAppWindow` (`NativeTaoBridge.nativeIsWindowHung`) every 2 s and logs `SEVERE` + a full thread dump once a window has been hung past the grace period on top of Windows' own ~5 s threshold. The probe is a pure OS-state query — it sends nothing to the loop, unlike a `SendMessageTimeout(WM_NULL)` probe, whose inline sent message is exactly the re-entrancy that deadlocked #640. HWNDs are cached on `WINDOW_READY` from the event-loop thread: resolving one later goes through the native `WINDOWS` map, whose lock a stalled loop may hold. **The app-facing shape is Electron's**: the framework logs and raises `onUnresponsive` / `onResponsive` (`NucleusApplicationScope`, `TaoApplication` — `webContents`' `unresponsive` / `responsive`), and ships **no UI of its own**; the "wait or quit" prompt is the app's to build, as it is in Electron, Chromium's HangWatcher, IntelliJ's PerformanceWatcher and Unreal's `FThreadHeartBeat`. Both callbacks run on their own `nucleus-tao-watchdog-events` thread — not the UI thread (the stuck one, so anything posted to `Dispatchers.Main` would only run once the stall ends) and not the sampling thread, so a listener that blocks in a "wait or quit" prompt delays the next callback, never the detection. Off by default under a debug agent (a breakpoint on the UI thread is indistinguishable from a stall — the reason Unreal ships `HangDuration=0`); a poll that overslept by >10 s is read as a system suspend, which drops the episode and ignores the next 30 s (Electron #53529's `base::PowerMonitor` rule). `expectUnresponsive { }` (`NucleusApplicationScope`, `TaoApplication`) declares a long synchronous operation so it is not reported — Chromium's `InvalidateActiveExpectations()`, and the reason the global switch is not the only recourse. The watchdog thread parks while no window is registered (HangWatcher does the same with an empty watch list). `-Dnucleus.tao.watchdog=false` disables it (`=true` forces it on under a debugger), `-Dnucleus.tao.watchdogGraceMs=` retunes it, `-Dnucleus.tao.watchdogDialog=true` also pops the native dialog (from the watchdog thread — the loop thread is the stuck one, #622's constraint; `nucleus.tao.fatalErrorDialog=false` suppresses it too, as it does every native modal). Windows only: macOS has no public "not responding" query and X11's `_NET_WM_PING` perturbs the loop it observes. E2E: `EventLoopWatchdogHeadfulCases` (real window, real freeze), black-box switch smoke `./gradlew :decorated-window-tao:taoWatchdogSmoke` (prints `severe=N unresponsive=N responsive=N`; `-Dnucleus.tao.watchdogDialog=true -Dnucleus.tao.watchdog.smoke.holdMs=20000` to look at the dialog) -- **macOS trackpad on Tao** (#652–#654): scroll deltas are AWT-shaped (`preciseWheelRotation`, no display scale). Trackpad gestures reach Compose as `PanStart` / `PanMove` / `PanEnd` (`panOffset` = AWT delta × 10 dp), wheel notches as `Scroll`; foundation's `Modifier.scrollable` handles both. Custom handlers that only listen for `PointerEventType.Scroll` must also handle Pan, or the app can set `-Dnucleus.tao.trackpadPanEvents=false` to get AWT-style `Scroll` for everything. Everything scroll-related enters the scene through `TaoSceneScrollRouter` (window + NSPanel popups); the phase wire (Rust `SCROLL_GESTURE_*`, `popup_panel.m`, `TaoScrollGesturePhase`) is guarded by `TaoScrollWireDriftTest` +- **macOS trackpad on Tao** (#652–#654, #660): scroll deltas are AWT-shaped (`preciseWheelRotation`, no display scale).

Everything scroll-related enters the scene through `TaoSceneScrollRouter` (window + NSPanel popups); the phase wire (Rust `SCROLL_GESTURE_*`, `popup_panel.m`, `TaoScrollGesturePhase`) is guarded by `TaoScrollWireDriftTest`. Platform-recognized pinch is `ScaleStart` / `ScaleChange` / `ScaleEnd` (`scaleFactor` = per-event ratio) via `dispatchTrackpadScale` — not two synthetic Touch contacts; `Modifier.transformable` and MapLibre consume that path, while `detectTransformGestures` still only sees two-finger rotate. Linux/Windows pinch (GDK / Ctrl+wheel) uses the same Scale events. - macOS Liquid Glass enabled by default via `macOsSdkVersion = "26.0"` (vtool SDK patching) - **PKG has two channels**, chosen by `macOS { pkg { appStore } }` (default `true`); whether `TargetFormat.Pkg` is a store format is `JvmApplicationDistributions.isSandboxed(format)`, not an enum property. App Store PKG = sandboxed pipeline, "3rd Party Mac Developer" certificates, `productsign` after the build, never notarized (Transporter upload). `appStore = false` = Developer ID PKG on the DMG pipeline (#249): electron-builder signs the installer itself from `pkg.identity` = the **bare** `NAME (TEAMID)` (it prepends "Developer ID Installer" and rejects a prefixed qualifier; `CSC_IDENTITY_AUTO_DISCOVERY=false` means no identity ⇒ silently unsigned, which the task catches with `pkgutil --check-signature`), a DSL keychain travels as `CSC_KEYCHAIN`, and `notarizePkg` notarizes the `.pkg`. `pkg { preInstall / postInstall }` are staged in `/build/pkg-scripts` for `pkgbuild --scripts` (shebang required); the App Store rejects install scripts (error 90254), so they require `appStore = false`. **The staged `preinstall` / `postinstall` are Nucleus shims, not the app's script**: electron-builder sets `BundlePre/PostInstallScriptPath` *and* passes `--scripts`, so `PackageInfo` declares each script twice and Installer runs it twice (confirmed on a real install). The shim skips the per-bundle pass (`$2` is the `.app`) and execs the app's copy, staged as `nucleus-app-pre` / `nucleus-app-post` — names electron-builder's `name.includes("preinstall")` scan must not match. Runtime: gate sandbox-sensitive features on `ExecutableRuntime.isSandboxed()` (`APP_SANDBOX_CONTAINER_ID`), never on `isPkg()` — that is also what makes a Developer ID PKG self-updatable (`NucleusUpdater.isUpdateSupported`) while the App Store build stays excluded - **Node.js is provisioned, not required**: every format except `TargetFormat.RawAppImage` is built by electron-builder, which the plugin installs with `npm ci --ignore-scripts` against an embedded lock file — so packaging needs a Node.js. It downloads one from `nodejs.org` (verified against the release's `SHASUMS256.txt`) into `/nucleus/nodejs`, exactly like the GraalVM and packaging JDK toolchains, and the three share `ToolchainDownloads`. Configure with `nativeDistributions { nodejs { autoDownload / version / installDir } }`; `version` is a major line (`"22"`, the default), `"lts"`, or a pinned release, and a floating line is sticky once downloaded. Precedence: the `compose.electronBuilder.nodePath` Gradle property, then `NUCLEUS_NODE_HOME`, then the provisioned install, then `PATH` (also the fallback when the download fails). CI therefore runs **no** `actions/setup-node` — only a cache of `~/.gradle/nucleus/nodejs`. `release-desktop`'s `universal-macos` job runs electron-builder outside the plugin, so `build-macos-universal/provision-electron-builder.sh` mirrors it: same Node resolution rule, same install layout and marker (the cache entry is shared), and `npm ci --ignore-scripts` against the plugin's embedded lock file — never `npx --yes` diff --git a/decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/DecoratedWindow.kt b/decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/DecoratedWindow.kt index 237ebf0ea..4b54b957e 100644 --- a/decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/DecoratedWindow.kt +++ b/decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/DecoratedWindow.kt @@ -420,8 +420,8 @@ internal fun ApplicationScope.openDecoratedWindow( // Trackpad pinch / rotate / smart-magnify, intercepted before AppKit // dispatches them down the responder chain (Tao 0.35 doesn't surface - // these events).

A Scale event lists only the mouse pointer, so Compose read the rotation contacts as released: every rotate step re-pressed them (a touch tap per step) and never rotated. Carrying the contacts on the Scale event does not work either — the factor is stamped on every pointer and foundation multiplies it per pointer. The gesture that begins first now owns it: during a pinch rotate steps are dropped, during a rotation magnify widens the contacts as before. Adds nativeDiagInjectTrackpadGesture (gated by NUCLEUS_TAO_INPUT_INJECTION): a type-29 CGEvent with the window set through field 51 and CGEventSetWindowLocation, posted to NSApp so the gesture monitor sees it as a real pinch. MacOsTrackpadScaleHeadfulCases covers Scale at the cursor, the 1% transformable zoom, the map-edge hit test, smart-magnify, cancel, rotate, and both interleaving orders.

Do not treat `IDEAL_API.md - **Logging**: `java.util.logging` is the single facade for every runtime module — no SLF4J dependency forced on consumers, no raw `println` / `System.err` in `src/main`. Logger names must be the fully-qualified class name (or an explicit `dev.nucleusframework.*` string) so the whole framework sits under one JUL namespace. `allowNucleusRuntimeLogging = true` is an opt-in convenience that raises the `dev.nucleusframework` logger to `nucleusLoggingLevel` and attaches a colored console handler; apps that configure JUL themselves (`logging.properties`, `jul-to-slf4j`) leave it `false` and Nucleus never touches the JUL configuration - `decorated-window-tao` is the only window backend (no AWT, native event-loop-driven, true Windows fullscreen, GraalVM native-image first-class). The AWT-based backends (`decorated-window-awt` / `-jbr` / `-jni`), `NucleusBackend`, `LocalNucleusBackend`, the `backend =` parameter of `nucleusApplication`, and `NucleusWindowUnsafe.awtWindow` / `awtDialog` were all removed in 2.6. Compose Desktop's AWT `Window` / `Dialog` / `Tray` are unsupported — use `DecoratedWindow`, `HostedWindow` / `HostedDialog`, and an AWT-free tray - **Event-loop watchdog** (#643): a stalled loop produces no exception — to the JVM the thread is a healthy `RUNNABLE` / `_thread_in_native` — and `TaoApplication.rethrowPendingFatal` sits *after* `nativeRunBlocking`, which a deadlocked loop never leaves, so #640 froze silently. `TaoEventLoopWatchdog` is a min-priority daemon thread that polls `IsHungAppWindow` (`NativeTaoBridge.nativeIsWindowHung`) every 2 s and logs `SEVERE` + a full thread dump once a window has been hung past the grace period on top of Windows' own ~5 s threshold. The probe is a pure OS-state query — it sends nothing to the loop, unlike a `SendMessageTimeout(WM_NULL)` probe, whose inline sent message is exactly the re-entrancy that deadlocked #640. HWNDs are cached on `WINDOW_READY` from the event-loop thread: resolving one later goes through the native `WINDOWS` map, whose lock a stalled loop may hold. **The app-facing shape is Electron's**: the framework logs and raises `onUnresponsive` / `onResponsive` (`NucleusApplicationScope`, `TaoApplication` — `webContents`' `unresponsive` / `responsive`), and ships **no UI of its own**; the "wait or quit" prompt is the app's to build, as it is in Electron, Chromium's HangWatcher, IntelliJ's PerformanceWatcher and Unreal's `FThreadHeartBeat`. Both callbacks run on their own `nucleus-tao-watchdog-events` thread — not the UI thread (the stuck one, so anything posted to `Dispatchers.Main` would only run once the stall ends) and not the sampling thread, so a listener that blocks in a "wait or quit" prompt delays the next callback, never the detection. Off by default under a debug agent (a breakpoint on the UI thread is indistinguishable from a stall — the reason Unreal ships `HangDuration=0`); a poll that overslept by >10 s is read as a system suspend, which drops the episode and ignores the next 30 s (Electron #53529's `base::PowerMonitor` rule). `expectUnresponsive { }` (`NucleusApplicationScope`, `TaoApplication`) declares a long synchronous operation so it is not reported — Chromium's `InvalidateActiveExpectations()`, and the reason the global switch is not the only recourse. The watchdog thread parks while no window is registered (HangWatcher does the same with an empty watch list). `-Dnucleus.tao.watchdog=false` disables it (`=true` forces it on under a debugger), `-Dnucleus.tao.watchdogGraceMs=` retunes it, `-Dnucleus.tao.watchdogDialog=true` also pops the native dialog (from the watchdog thread — the loop thread is the stuck one, #622's constraint; `nucleus.tao.fatalErrorDialog=false` suppresses it too, as it does every native modal). Windows only: macOS has no public "not responding" query and X11's `_NET_WM_PING` perturbs the loop it observes. E2E: `EventLoopWatchdogHeadfulCases` (real window, real freeze), black-box switch smoke `./gradlew :decorated-window-tao:taoWatchdogSmoke` (prints `severe=N unresponsive=N responsive=N`; `-Dnucleus.tao.watchdogDialog=true -Dnucleus.tao.watchdog.smoke.holdMs=20000` to look at the dialog) -- **macOS trackpad on Tao** (#652–#654, #660): scroll deltas are AWT-shaped (`preciseWheelRotation`, no display scale).

Magnify and rotate interleave on a real trackpad and the two models cannot overlap (a Scale event without the contacts reads as their release → a touch tap per step; one carrying them stamps the factor on every pointer and foundation multiplies it per pointer), so the gesture that begins first owns it: during a pinch rotate steps are dropped, during a rotation magnify widens the contacts.

Linux/Windows pinch (GDK / Ctrl+wheel) uses the same Scale events. - macOS Liquid Glass enabled by default via `macOsSdkVersion = "26.0"` (vtool SDK patching) - **PKG has two channels**, chosen by `macOS { pkg { appStore } }` (default `true`); whether `TargetFormat.Pkg` is a store format is `JvmApplicationDistributions.isSandboxed(format)`, not an enum property. App Store PKG = sandboxed pipeline, "3rd Party Mac Developer" certificates, `productsign` after the build, never notarized (Transporter upload). `appStore = false` = Developer ID PKG on the DMG pipeline (#249): electron-builder signs the installer itself from `pkg.identity` = the **bare** `NAME (TEAMID)` (it prepends "Developer ID Installer" and rejects a prefixed qualifier; `CSC_IDENTITY_AUTO_DISCOVERY=false` means no identity ⇒ silently unsigned, which the task catches with `pkgutil --check-signature`), a DSL keychain travels as `CSC_KEYCHAIN`, and `notarizePkg` notarizes the `.pkg`. `pkg { preInstall / postInstall }` are staged in `/build/pkg-scripts` for `pkgbuild --scripts` (shebang required); the App Store rejects install scripts (error 90254), so they require `appStore = false`. **The staged `preinstall` / `postinstall` are Nucleus shims, not the app's script**: electron-builder sets `BundlePre/PostInstallScriptPath` *and* passes `--scripts`, so `PackageInfo` declares each script twice and Installer runs it twice (confirmed on a real install). The shim skips the per-bundle pass (`$2` is the `.app`) and execs the app's copy, staged as `nucleus-app-pre` / `nucleus-app-post` — names electron-builder's `name.includes("preinstall")` scan must not match. Runtime: gate sandbox-sensitive features on `ExecutableRuntime.isSandboxed()` (`APP_SANDBOX_CONTAINER_ID`), never on `isPkg()` — that is also what makes a Developer ID PKG self-updatable (`NucleusUpdater.isUpdateSupported`) while the App Store build stays excluded - **Node.js is provisioned, not required**: every format except `TargetFormat.RawAppImage` is built by electron-builder, which the plugin installs with `npm ci --ignore-scripts` against an embedded lock file — so packaging needs a Node.js. It downloads one from `nodejs.org` (verified against the release's `SHASUMS256.txt`) into `/nucleus/nodejs`, exactly like the GraalVM and packaging JDK toolchains, and the three share `ToolchainDownloads`. Configure with `nativeDistributions { nodejs { autoDownload / version / installDir } }`; `version` is a major line (`"22"`, the default), `"lts"`, or a pinned release, and a floating line is sticky once downloaded. Precedence: the `compose.electronBuilder.nodePath` Gradle property, then `NUCLEUS_NODE_HOME`, then the provisioned install, then `PATH` (also the fallback when the download fails). CI therefore runs **no** `actions/setup-node` — only a cache of `~/.gradle/nucleus/nodejs`. `release-desktop`'s `universal-macos` job runs electron-builder outside the plugin, so `build-macos-universal/provision-electron-builder.sh` mirrors it: same Node resolution rule, same install layout and marker (the cache entry is shared), and `npm ci --ignore-scripts` against the plugin's embedded lock file — never `npx --yes` diff --git a/decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/ffi/NativeMetalBridge.kt b/decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/ffi/NativeMetalBridge.kt index 2edcb9e8d..37089090f 100644 --- a/decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/ffi/NativeMetalBridge.kt +++ b/decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/ffi/NativeMetalBridge.kt @@ -546,6 +546,28 @@ internal object NativeMetalBridge { momentumPhase: Int, ): Boolean + /** + * Headful e2e only (#660): feeds a synthetic magnify / rotate / + * smart-magnify NSEvent on `NSApp`'s queue (`postEvent`, delivered after + * the current callback returns), so the trackpad gesture monitor handles + * it as a real trackpad pinch.

Do not treat `IDEAL_API.md - **Logging**: `java.util.logging` is the single facade for every runtime module — no SLF4J dependency forced on consumers, no raw `println` / `System.err` in `src/main`. Logger names must be the fully-qualified class name (or an explicit `dev.nucleusframework.*` string) so the whole framework sits under one JUL namespace. `allowNucleusRuntimeLogging = true` is an opt-in convenience that raises the `dev.nucleusframework` logger to `nucleusLoggingLevel` and attaches a colored console handler; apps that configure JUL themselves (`logging.properties`, `jul-to-slf4j`) leave it `false` and Nucleus never touches the JUL configuration - `decorated-window-tao` is the only window backend (no AWT, native event-loop-driven, true Windows fullscreen, GraalVM native-image first-class). The AWT-based backends (`decorated-window-awt` / `-jbr` / `-jni`), `NucleusBackend`, `LocalNucleusBackend`, the `backend =` parameter of `nucleusApplication`, and `NucleusWindowUnsafe.awtWindow` / `awtDialog` were all removed in 2.6. Compose Desktop's AWT `Window` / `Dialog` / `Tray` are unsupported — use `DecoratedWindow`, `HostedWindow` / `HostedDialog`, and an AWT-free tray - **Event-loop watchdog** (#643): a stalled loop produces no exception — to the JVM the thread is a healthy `RUNNABLE` / `_thread_in_native` — and `TaoApplication.rethrowPendingFatal` sits *after* `nativeRunBlocking`, which a deadlocked loop never leaves, so #640 froze silently. `TaoEventLoopWatchdog` is a min-priority daemon thread that polls `IsHungAppWindow` (`NativeTaoBridge.nativeIsWindowHung`) every 2 s and logs `SEVERE` + a full thread dump once a window has been hung past the grace period on top of Windows' own ~5 s threshold. The probe is a pure OS-state query — it sends nothing to the loop, unlike a `SendMessageTimeout(WM_NULL)` probe, whose inline sent message is exactly the re-entrancy that deadlocked #640. HWNDs are cached on `WINDOW_READY` from the event-loop thread: resolving one later goes through the native `WINDOWS` map, whose lock a stalled loop may hold. **The app-facing shape is Electron's**: the framework logs and raises `onUnresponsive` / `onResponsive` (`NucleusApplicationScope`, `TaoApplication` — `webContents`' `unresponsive` / `responsive`), and ships **no UI of its own**; the "wait or quit" prompt is the app's to build, as it is in Electron, Chromium's HangWatcher, IntelliJ's PerformanceWatcher and Unreal's `FThreadHeartBeat`. Both callbacks run on their own `nucleus-tao-watchdog-events` thread — not the UI thread (the stuck one, so anything posted to `Dispatchers.Main` would only run once the stall ends) and not the sampling thread, so a listener that blocks in a "wait or quit" prompt delays the next callback, never the detection. Off by default under a debug agent (a breakpoint on the UI thread is indistinguishable from a stall — the reason Unreal ships `HangDuration=0`); a poll that overslept by >10 s is read as a system suspend, which drops the episode and ignores the next 30 s (Electron #53529's `base::PowerMonitor` rule). `expectUnresponsive { }` (`NucleusApplicationScope`, `TaoApplication`) declares a long synchronous operation so it is not reported — Chromium's `InvalidateActiveExpectations()`, and the reason the global switch is not the only recourse. The watchdog thread parks while no window is registered (HangWatcher does the same with an empty watch list). `-Dnucleus.tao.watchdog=false` disables it (`=true` forces it on under a debugger), `-Dnucleus.tao.watchdogGraceMs=` retunes it, `-Dnucleus.tao.watchdogDialog=true` also pops the native dialog (from the watchdog thread — the loop thread is the stuck one, #622's constraint; `nucleus.tao.fatalErrorDialog=false` suppresses it too, as it does every native modal). Windows only: macOS has no public "not responding" query and X11's `_NET_WM_PING` perturbs the loop it observes. E2E: `EventLoopWatchdogHeadfulCases` (real window, real freeze), black-box switch smoke `./gradlew :decorated-window-tao:taoWatchdogSmoke` (prints `severe=N unresponsive=N responsive=N`; `-Dnucleus.tao.watchdogDialog=true -Dnucleus.tao.watchdog.smoke.holdMs=20000` to look at the dialog) -- **macOS trackpad on Tao** (#652–#654, #660): scroll deltas are AWT-shaped (`preciseWheelRotation`, no display scale). Trackpad two-finger swipe reaches Compose as `PanStart` / `PanMove` / `PanEnd` (`panOffset` = AWT delta × 10 dp), wheel notches as `Scroll`; foundation's `Modifier.scrollable` handles both. Custom handlers that only listen for `PointerEventType.Scroll` must also handle Pan, or the app can set `-Dnucleus.tao.trackpadPanEvents=false` to get AWT-style `Scroll` for everything. Everything scroll-related enters the scene through `TaoSceneScrollRouter` (window + NSPanel popups); the phase wire (Rust `SCROLL_GESTURE_*`, `popup_panel.m`, `TaoScrollGesturePhase`) is guarded by `TaoScrollWireDriftTest`. Platform-recognized pinch is `ScaleStart` / `ScaleChange` / `ScaleEnd` (`scaleFactor` = per-event ratio) via `dispatchTrackpadScale` — not two synthetic Touch contacts; `Modifier.transformable` and MapLibre consume that path, while `detectTransformGestures` still only sees two-finger rotate (two synthetic Touch contacts). Magnify and rotate interleave on a real trackpad and the two models cannot overlap (a Scale event without the contacts reads as their release → a touch tap per step; one carrying them stamps the factor on every pointer and foundation multiplies it per pointer), so the gesture that begins first owns it: during a pinch rotate steps are dropped, during a rotation magnify widens the contacts.

App Store PKG = sandboxed pipeline, "3rd Party Mac Developer" certificates, `productsign` after the build, never notarized (Transporter upload). `appStore = false` = Developer ID PKG on the DMG pipeline (#249): electron-builder signs the installer itself from `pkg.identity` = the **bare** `NAME (TEAMID)` (it prepends "Developer ID Installer" and rejects a prefixed qualifier; `CSC_IDENTITY_AUTO_DISCOVERY=false` means no identity ⇒ silently unsigned, which the task catches with `pkgutil --check-signature`), a DSL keychain travels as `CSC_KEYCHAIN`, and `notarizePkg` notarizes the `.pkg`. `pkg { preInstall / postInstall }` are staged in `/build/pkg-scripts` for `pkgbuild --scripts` (shebang required); the App Store rejects install scripts (error 90254), so they require `appStore = false`. **The staged `preinstall` / `postinstall` are Nucleus shims, not the app's script**: electron-builder sets `BundlePre/PostInstallScriptPath` *and* passes `--scripts`, so `PackageInfo` declares each script twice and Installer runs it twice (confirmed on a real install). The shim skips the per-bundle pass (`$2` is the `.app`) and execs the app's copy, staged as `nucleus-app-pre` / `nucleus-app-post` — names electron-builder's `name.includes("preinstall")` scan must not match. Runtime: gate sandbox-sensitive features on `ExecutableRuntime.isSandboxed()` (`APP_SANDBOX_CONTAINER_ID`), never on `isPkg()` — that is also what makes a Developer ID PKG self-updatable (`NucleusUpdater.isUpdateSupported`) while the App Store build stays excluded - **Node.js is provisioned, not required**: every format except `TargetFormat.RawAppImage` is built by electron-builder, which the plugin installs with `npm ci --ignore-scripts` against an embedded lock file — so packaging needs a Node.js. It downloads one from `nodejs.org` (verified against the release's `SHASUMS256.txt`) into `/nucleus/nodejs`, exactly like the GraalVM and packaging JDK toolchains, and the three share `ToolchainDownloads`. Configure with `nativeDistributions { nodejs { autoDownload / version / installDir } }`; `version` is a major line (`"22"`, the default), `"lts"`, or a pinned release, and a floating line is sticky once downloaded. Precedence: the `compose.electronBuilder.nodePath` Gradle property, then `NUCLEUS_NODE_HOME`, then the provisioned install, then `PATH` (also the fallback when the download fails). CI therefore runs **no** `actions/setup-node` — only a cache of `~/.gradle/nucleus/nodejs`. `release-desktop`'s `universal-macos` job runs electron-builder outside the plugin, so `build-macos-universal/provision-electron-builder.sh` mirrors it: same Node resolution rule, same install layout and marker (the cache entry is shared), and `npm ci --ignore-scripts` against the plugin's embedded lock file — never `npx --yes` diff --git a/decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/scene/TaoComposeSceneHost.kt b/decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/scene/TaoComposeSceneHost.kt index 9ca4274c5..76f31d324 100644 --- a/decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/scene/TaoComposeSceneHost.kt +++ b/decorated-window-tao/src/main/kotlin/dev/nucleusframework/window/tao/scene/TaoComposeSceneHost.kt @@ -851,6 +851,7 @@ internal class TaoComposeSceneHost( fun onFocusChanged(focused: Boolean) { windowInfo.isWindowFocused = focused + if (!focused) interruptRotation() if (!focused && isPressed) { // Whatever stole focus mid-click (a native context-menu tracking // session, a compositor drag) owns the pointer now and will eat @@ -1259,6 +1260,7 @@ internal class TaoComposeSceneHost( currentKeyboardModifiers = taoKeyboardModifiers(window.modifierState) windowInfo.keyboardModifiers = currentKeyboardModifiers if (!pointerDeadband.shouldDispatchMove(xPx, yPx, scale)) return + interruptRotation() scene?.sendPointerEvent( eventType = PointerEventType.Move, position = Offset(pointerDeadband.x, pointerDeadband.y), @@ -1270,6 +1272,7 @@ internal class TaoComposeSceneHost( fun onPointerExited() { currentKeyboardModifiers = taoKeyboardModifiers(window.modifierState) windowInfo.keyboardModifiers = currentKeyboardModifiers + interruptRotation() scene?.sendPointerEvent( eventType = PointerEventType.Exit, position = Offset(pointerDeadband.x, pointerDeadband.y), @@ -1291,6 +1294,7 @@ internal class TaoComposeSceneHost( // A click ends a trackpad gesture for Compose too (a tap to stop a // fling must not race an open pan session). if (pressed) scrollRouter.finishPan() + interruptRotation() val composeButton = mapButton(buttonCode) currentKeyboardModifiers = taoKeyboardModifiers(window.modifierState) windowInfo.keyboardModifiers = currentKeyboardModifiers @@ -1341,6 +1345,8 @@ internal class TaoComposeSceneHost( fun onPointerScroll(event: TaoPointerScrollEvent) { currentKeyboardModifiers = taoKeyboardModifiers(window.modifierState) windowInfo.keyboardModifiers = currentKeyboardModifiers + // A rotation owns the fingers: a mouse-only Pan / Scroll would release its contacts. + if (rotateActive) return scrollRouter.onScroll(pointerDeadband.x, pointerDeadband.y, event, currentKeyboardModifiers) } @@ -1364,6 +1370,12 @@ internal class TaoComposeSceneHost( // the trackpad until it ends: during a pinch, rotate steps are dropped // (foundation abandons a touch gesture on any Scale event anyway); during // a rotation, magnify steps widen the contacts, as before #660. + // + // The same holds for every other mouse-only event: the contacts never + // coexist with one.

On macOS the only touch pointers are the trackpad rotation's synthetic contacts, so a rotation with the cursor near the top of a window called dragWindow(), which replays the last real mouseDown through performWindowDragWithEvent. Touch no longer arms the drag on macOS. Adds the overnight gesture monkey: trackpad / chaos / burst sessions back to back in a real DecoratedWindow with a TitleBar and content animating every frame (a fresh window every 15 min, -Dnucleus.tao.headful.monkeyNightMinutes, one 60 s window by default), a quarter of the gestures centred in the title bar. It checks the model plus the chrome: no move, resize, maximize, fullscreen or window drag, and frames keep coming. Also adds a deterministic case: a real click on the bar, then rotations there.

The night now samples the system cursor and the window's active / minimized state at every checkpoint: a moved cursor, a minimized window or a background window without frames aborts the session as "disturbed", waits for 30 s of idle cursor and re-baselines. A drag started by the synthetic contacts is still a failure and is checked first. Failures and progress lines carry the time.

The Linux host opened a Scale gesture and pressed the rotation contacts side by side, so every update of an ordinary pinch released and re-pressed them (a touch tap per update) and a rotation never rotated. A pinch now opens as Scale and only accumulates its angle; the rotation takes over (Scale closes, contacts pressed already turned) once it has turned 10° while the zoom stays within ±10 %. Ported the macOS rules too: a cursor move, click, focus loss or scroll during a rotation interrupts it, and magnify folded into a rotation is clamped. Also fixed on the way: - GDK's angle_delta is clockwise-positive on screen: Linux rotation ran backwards (pre-existing). - A Linux rotation over the title bar started a compositor move. The contacts now carry TaoTrackpadRotationContacts ids, which TitleBar excludes on every platform instead of the macOS-only check. - An interrupted rotation sent the contacts' Release before cancelPointerInput(), i.e. an unconsumed touch-up: a tap. Cancel first (both hosts). LinuxTrackpadPinchHeadfulCases injects GdkEventTouchpadPinch through the GtkWindow's event signal (nativeLinuxInjectGdkTouchpadPinch), so touch.rs and the host run as for a real pinch.

Do not treat `IDEAL_API.md - **Logging**: `java.util.logging` is the single facade for every runtime module — no SLF4J dependency forced on consumers, no raw `println` / `System.err` in `src/main`. Logger names must be the fully-qualified class name (or an explicit `dev.nucleusframework.*` string) so the whole framework sits under one JUL namespace. `allowNucleusRuntimeLogging = true` is an opt-in convenience that raises the `dev.nucleusframework` logger to `nucleusLoggingLevel` and attaches a colored console handler; apps that configure JUL themselves (`logging.properties`, `jul-to-slf4j`) leave it `false` and Nucleus never touches the JUL configuration - `decorated-window-tao` is the only window backend (no AWT, native event-loop-driven, true Windows fullscreen, GraalVM native-image first-class). The AWT-based backends (`decorated-window-awt` / `-jbr` / `-jni`), `NucleusBackend`, `LocalNucleusBackend`, the `backend =` parameter of `nucleusApplication`, and `NucleusWindowUnsafe.awtWindow` / `awtDialog` were all removed in 2.6. Compose Desktop's AWT `Window` / `Dialog` / `Tray` are unsupported — use `DecoratedWindow`, `HostedWindow` / `HostedDialog`, and an AWT-free tray - **Event-loop watchdog** (#643): a stalled loop produces no exception — to the JVM the thread is a healthy `RUNNABLE` / `_thread_in_native` — and `TaoApplication.rethrowPendingFatal` sits *after* `nativeRunBlocking`, which a deadlocked loop never leaves, so #640 froze silently. `TaoEventLoopWatchdog` is a min-priority daemon thread that polls `IsHungAppWindow` (`NativeTaoBridge.nativeIsWindowHung`) every 2 s and logs `SEVERE` + a full thread dump once a window has been hung past the grace period on top of Windows' own ~5 s threshold. The probe is a pure OS-state query — it sends nothing to the loop, unlike a `SendMessageTimeout(WM_NULL)` probe, whose inline sent message is exactly the re-entrancy that deadlocked #640. HWNDs are cached on `WINDOW_READY` from the event-loop thread: resolving one later goes through the native `WINDOWS` map, whose lock a stalled loop may hold. **The app-facing shape is Electron's**: the framework logs and raises `onUnresponsive` / `onResponsive` (`NucleusApplicationScope`, `TaoApplication` — `webContents`' `unresponsive` / `responsive`), and ships **no UI of its own**; the "wait or quit" prompt is the app's to build, as it is in Electron, Chromium's HangWatcher, IntelliJ's PerformanceWatcher and Unreal's `FThreadHeartBeat`. Both callbacks run on their own `nucleus-tao-watchdog-events` thread — not the UI thread (the stuck one, so anything posted to `Dispatchers.Main` would only run once the stall ends) and not the sampling thread, so a listener that blocks in a "wait or quit" prompt delays the next callback, never the detection. Off by default under a debug agent (a breakpoint on the UI thread is indistinguishable from a stall — the reason Unreal ships `HangDuration=0`); a poll that overslept by >10 s is read as a system suspend, which drops the episode and ignores the next 30 s (Electron #53529's `base::PowerMonitor` rule). `expectUnresponsive { }` (`NucleusApplicationScope`, `TaoApplication`) declares a long synchronous operation so it is not reported — Chromium's `InvalidateActiveExpectations()`, and the reason the global switch is not the only recourse. The watchdog thread parks while no window is registered (HangWatcher does the same with an empty watch list). `-Dnucleus.tao.watchdog=false` disables it (`=true` forces it on under a debugger), `-Dnucleus.tao.watchdogGraceMs=` retunes it, `-Dnucleus.tao.watchdogDialog=true` also pops the native dialog (from the watchdog thread — the loop thread is the stuck one, #622's constraint; `nucleus.tao.fatalErrorDialog=false` suppresses it too, as it does every native modal). Windows only: macOS has no public "not responding" query and X11's `_NET_WM_PING` perturbs the loop it observes.

Magnify and rotate interleave on a real trackpad and the two models cannot overlap (a Scale event without the contacts reads as their release → a touch tap per step; one carrying them stamps the factor on every pointer and foundation multiplies it per pointer), so the gesture that begins first owns it: during a pinch rotate steps are dropped, during a rotation magnify widens the contacts (spacing clamped to 0.05–20×, past which `detectZoom` handed the app `Infinity` / `NaN`). The contacts never coexist with **any** mouse-only event: a rotation does not start while a pan is open (`TaoSceneScrollRouter.panOpen`), drops trackpad scroll and smart-magnify while it owns the fingers, and a real cursor move / click / exit / focus loss interrupts it (cancelled, not a tap; the rest of it is ignored until it ends).

GDK's `angle_delta` is clockwise-positive on screen, i.e. Compose's sense (no flip, unlike AppKit). The contacts carry `TaoTrackpadRotationContacts` ids, which is how `TitleBar` keeps them from arming a window drag on every platform (a Linux rotation over the bar started a compositor move). An interrupted rotation calls `cancelPointerInput()` **before** sending the contacts' Release — the other order delivers an unconsumed touch-up, i.e. a tap. Linux headful coverage: `LinuxTrackpadPinchHeadfulCases` (synthetic `GdkEventTouchpadPinch` through the GtkWindow's `event` signal via `nativeLinuxInjectGdkTouchpadPinch`; coordinates are toplevel-relative, so add `nativeLinuxContentOrigin`) and `TrackpadScaleHeadfulCases` (real Ctrl+wheel through the AWT Robot — X11 leg only, the Robot cannot inject on Wayland). - macOS Liquid Glass enabled by default via `macOsSdkVersion = "26.0"` (vtool SDK patching) - **PKG has two channels**, chosen by `macOS { pkg { appStore } }` (default `true`); whether `TargetFormat.Pkg` is a store format is `JvmApplicationDistributions.isSandboxed(format)`, not an enum property. App Store PKG = sandboxed pipeline, "3rd Party Mac Developer" certificates, `productsign` after the build, never notarized (Transporter upload). `appStore = false` = Developer ID PKG on the DMG pipeline (#249): electron-builder signs the installer itself from `pkg.identity` = the **bare** `NAME (TEAMID)` (it prepends "Developer ID Installer" and rejects a prefixed qualifier; `CSC_IDENTITY_AUTO_DISCOVERY=false` means no identity ⇒ silently unsigned, which the task catches with `pkgutil --check-signature`), a DSL keychain travels as `CSC_KEYCHAIN`, and `notarizePkg` notarizes the `.pkg`. `pkg { preInstall / postInstall }` are staged in `/build/pkg-scripts` for `pkgbuild --scripts` (shebang required); the App Store rejects install scripts (error 90254), so they require `appStore = false`. **The staged `preinstall` / `postinstall` are Nucleus shims, not the app's script**: electron-builder sets `BundlePre/PostInstallScriptPath` *and* passes `--scripts`, so `PackageInfo` declares each script twice and Installer runs it twice (confirmed on a real install). The shim skips the per-bundle pass (`$2` is the `.app`) and execs the app's copy, staged as `nucleus-app-pre` / `nucleus-app-post` — names electron-builder's `name.includes("preinstall")` scan must not match. Runtime: gate sandbox-sensitive features on `ExecutableRuntime.isSandboxed()` (`APP_SANDBOX_CONTAINER_ID`), never on `isPkg()` — that is also what makes a Developer ID PKG self-updatable (`NucleusUpdater.isUpdateSupported`) while the App Store build stays excluded - **Node.js is provisioned, not required**: every format except `TargetFormat.RawAppImage` is built by electron-builder, which the plugin installs with `npm ci --ignore-scripts` against an embedded lock file — so packaging needs a Node.js. It downloads one from `nodejs.org` (verified against the release's `SHASUMS256.txt`) into `/nucleus/nodejs`, exactly like the GraalVM and packaging JDK toolchains, and the three share `ToolchainDownloads`. Configure with `nativeDistributions { nodejs { autoDownload / version / installDir } }`; `version` is a major line (`"22"`, the default), `"lts"`, or a pinned release, and a floating line is sticky once downloaded.

The GraalVM pipeline passes the image name there, so with a custom graalvm.imageName the %APPDATA%\ directory (NucleusApp.appId, used for FileKit) survived the uninstall. The generated NSIS include now also removes %APPDATA%\ from customUnInstall, under electron-builder's own condition (--delete-app-data, or deleteAppDataOnUninstall outside an update). The protocol registration shares that include, since NSIS allows one customUnInstall macro.

NSIS installs of JVM apps are laid out as App.exe + app\App.cfg at the root and versions\\{app,runtime}, so installAndRestart installs the new version next to the running one, launches it, and exits once the new version's first window is on screen. - plugin: versioned app image layout and NSIS hooks that neither kill the running app nor delete its files when NUCLEUS_HOT_UPDATE=1 - updater: install while running, handoff on the new version's first frame, cleanup of retired versions, classic fallback when the hot path cannot start - multi-instance: cross-process install lock, pendingRestartVersion / restartToInstalledVersion, explicit relaunchArguments - fix: PowerShell update scripts are written with a BOM, so updates work for accented profile paths (classic path included) - fix: the post-update event is only reported when its target version runs - E2E: examples/hot-update-demo + scripts/windows-hot-update-e2e.ps1 --- CLAUDE.md | 3 +- core-runtime/api/core-runtime.api | 22 + .../core/runtime/SingleInstanceManager.kt | 22 +- .../core/runtime/UpdateHandoff.kt | 227 +++++++++ .../core/runtime/UpdateHandoffTest.kt | 97 ++++ .../nucleusframework/window/tao/TaoWindow.kt | 4 + examples/hot-update-demo/build.gradle.kts | 57 +++ .../src/main/kotlin/hotupdatedemo/Main.kt | 119 +++++ .../internal/WindowsHotUpdateLayout.kt | 96 ++++ .../internal/WindowsHotUpdateNsis.kt | 93 ++++ .../ElectronBuilderConfigGenerator.kt | 25 +- .../AbstractElectronBuilderPackageTask.kt | 107 +++- .../internal/WindowsHotUpdateLayoutTest.kt | 92 ++++ .../ElectronBuilderMsiConfigTest.kt | 2 +- .../ElectronBuilderNsisConfigTest.kt | 2 +- scripts/windows-hot-update-e2e.ps1 | 465 ++++++++++++++++++ settings.gradle.kts | 1 + updater-runtime/api/updater-runtime.api | 4 + .../updater/NucleusUpdater.kt | 102 +++- .../internal/InstalledVersionWatcher.kt | 83 ++++ .../updater/internal/PlatformInstaller.kt | 12 +- .../updater/internal/WindowsHotUpdate.kt | 418 ++++++++++++++++ .../updater/internal/WindowsUpdateScript.kt | 57 ++- .../updater/UpdateEventTest.kt | 29 +- .../WindowsHotUpdateMultiInstanceTest.kt | 98 ++++ .../updater/WindowsHotUpdateTest.kt | 145 ++++++ 26 files changed, 2320 insertions(+), 62 deletions(-) create mode 100644 core-runtime/src/main/kotlin/dev/nucleusframework/core/runtime/UpdateHandoff.kt create mode 100644 core-runtime/src/test/kotlin/dev/nucleusframework/core/runtime/UpdateHandoffTest.kt create mode 100644 examples/hot-update-demo/build.gradle.kts create mode 100644 examples/hot-update-demo/src/main/kotlin/hotupdatedemo/Main.kt create mode 100644 plugin-build/plugin/src/main/kotlin/dev/nucleusframework/desktop/application/internal/WindowsHotUpdateLayout.kt create mode 100644 plugin-build/plugin/src/main/kotlin/dev/nucleusframework/desktop/application/internal/WindowsHotUpdateNsis.kt create mode 100644 plugin-build/plugin/src/test/kotlin/dev/nucleusframework/desktop/application/internal/WindowsHotUpdateLayoutTest.kt create mode 100644 scripts/windows-hot-update-e2e.ps1 create mode 100644 updater-runtime/src/main/kotlin/dev/nucleusframework/updater/internal/InstalledVersionWatcher.kt create mode 100644 updater-runtime/src/main/kotlin/dev/nucleusframework/updater/internal/WindowsHotUpdate.kt create mode 100644 updater-runtime/src/test/kotlin/dev/nucleusframework/updater/WindowsHotUpdateMultiInstanceTest.kt create mode 100644 updater-runtime/src/test/kotlin/dev/nucleusframework/updater/WindowsHotUpdateTest.kt diff --git a/CLAUDE.md b/CLAUDE.md index 7ad0d762e..eb560a4a2 100644 --- a/CLAUDE.md +++ b/CLAUDE.md @@ -9,7 +9,7 @@ Published releases are `2.5.x` (latest tag `v2.5.0`).

Do not treat `IDEAL_API.md - **Event-loop watchdog** (#643): a stalled loop produces no exception — to the JVM the thread is a healthy `RUNNABLE` / `_thread_in_native` — and `TaoApplication.rethrowPendingFatal` sits *after* `nativeRunBlocking`, which a deadlocked loop never leaves, so #640 froze silently. `TaoEventLoopWatchdog` is a min-priority daemon thread that polls `IsHungAppWindow` (`NativeTaoBridge.nativeIsWindowHung`) every 2 s and logs `SEVERE` + a full thread dump once a window has been hung past the grace period on top of Windows' own ~5 s threshold. The probe is a pure OS-state query — it sends nothing to the loop, unlike a `SendMessageTimeout(WM_NULL)` probe, whose inline sent message is exactly the re-entrancy that deadlocked #640. HWNDs are cached on `WINDOW_READY` from the event-loop thread: resolving one later goes through the native `WINDOWS` map, whose lock a stalled loop may hold. **The app-facing shape is Electron's**: the framework logs and raises `onUnresponsive` / `onResponsive` (`NucleusApplicationScope`, `TaoApplication` — `webContents`' `unresponsive` / `responsive`), and ships **no UI of its own**; the "wait or quit" prompt is the app's to build, as it is in Electron, Chromium's HangWatcher, IntelliJ's PerformanceWatcher and Unreal's `FThreadHeartBeat`. Both callbacks run on their own `nucleus-tao-watchdog-events` thread — not the UI thread (the stuck one, so anything posted to `Dispatchers.Main` would only run once the stall ends) and not the sampling thread, so a listener that blocks in a "wait or quit" prompt delays the next callback, never the detection. Off by default under a debug agent (a breakpoint on the UI thread is indistinguishable from a stall — the reason Unreal ships `HangDuration=0`); a poll that overslept by >10 s is read as a system suspend, which drops the episode and ignores the next 30 s (Electron #53529's `base::PowerMonitor` rule). `expectUnresponsive { }` (`NucleusApplicationScope`, `TaoApplication`) declares a long synchronous operation so it is not reported — Chromium's `InvalidateActiveExpectations()`, and the reason the global switch is not the only recourse. The watchdog thread parks while no window is registered (HangWatcher does the same with an empty watch list). `-Dnucleus.tao.watchdog=false` disables it (`=true` forces it on under a debugger), `-Dnucleus.tao.watchdogGraceMs=` retunes it, `-Dnucleus.tao.watchdogDialog=true` also pops the native dialog (from the watchdog thread — the loop thread is the stuck one, #622's constraint; `nucleus.tao.fatalErrorDialog=false` suppresses it too, as it does every native modal). Windows only: macOS has no public "not responding" query and X11's `_NET_WM_PING` perturbs the loop it observes. E2E: `EventLoopWatchdogHeadfulCases` (real window, real freeze), black-box switch smoke `./gradlew :decorated-window-tao:taoWatchdogSmoke` (prints `severe=N unresponsive=N responsive=N`; `-Dnucleus.tao.watchdogDialog=true -Dnucleus.tao.watchdog.smoke.holdMs=20000` to look at the dialog) - **macOS trackpad on Tao** (#652–#654, #660): scroll deltas are AWT-shaped (`preciseWheelRotation`, no display scale). Trackpad two-finger swipe reaches Compose as `PanStart` / `PanMove` / `PanEnd` (`panOffset` = AWT delta × 10 dp), wheel notches as `Scroll`; foundation's `Modifier.scrollable` handles both. Custom handlers that only listen for `PointerEventType.Scroll` must also handle Pan, or the app can set `-Dnucleus.tao.trackpadPanEvents=false` to get AWT-style `Scroll` for everything. Everything scroll-related enters the scene through `TaoSceneScrollRouter` (window + NSPanel popups); the phase wire (Rust `SCROLL_GESTURE_*`, `popup_panel.m`, `TaoScrollGesturePhase`) is guarded by `TaoScrollWireDriftTest`. Platform-recognized pinch is `ScaleStart` / `ScaleChange` / `ScaleEnd` (`scaleFactor` = per-event ratio) via `dispatchTrackpadScale` — not two synthetic Touch contacts; `Modifier.transformable` and MapLibre consume that path, while `detectTransformGestures` still only sees two-finger rotate (two synthetic Touch contacts). Magnify and rotate interleave on a real trackpad and the two models cannot overlap (a Scale event without the contacts reads as their release → a touch tap per step; one carrying them stamps the factor on every pointer and foundation multiplies it per pointer), so the gesture that begins first owns it: during a pinch rotate steps are dropped, during a rotation magnify widens the contacts (spacing clamped to 0.05–20×, past which `detectZoom` handed the app `Infinity` / `NaN`). The contacts never coexist with **any** mouse-only event: a rotation does not start while a pan is open (`TaoSceneScrollRouter.panOpen`), drops trackpad scroll and smart-magnify while it owns the fingers, and a real cursor move / click / exit / focus loss interrupts it (cancelled, not a tap; the rest of it is ignored until it ends). Headful coverage: `MacOsTrackpadGestureMonkeyHeadfulCases` (trackpad / chaos / burst profiles × seeds against an exact oracle of the host rules, plus degenerate cases: collapsing / exploding contacts, gestures far off-window, a window closed with 200 gestures queued) and `MacOsTrackpadScaleHeadfulCases` (gesture NSEvents via `nativeDiagInjectTrackpadGesture` — a type-29 CGEvent, window set through field 51 + the private `CGEventSetWindowLocation`, **posted** with `postEvent:atStart:`: a synchronous `sendEvent:` from the test body re-enters tao's event callback and deadlocks). Linux/Windows pinch (GDK / Ctrl+wheel) uses the same Scale events. **GDK differs**: it reports pinch and rotation as *one* gesture (every `GdkEventTouchpadPinch` carries a scale and an angle, `touch.rs` forwards a magnify then a rotate step for each), so first-come would make rotation unreachable — a pinch opens as Scale and only accumulates its angle, and the rotation takes over (Scale closes, contacts pressed already turned by that angle) once it has turned 10° while the zoom stays within ±10 %. GDK's `angle_delta` is clockwise-positive on screen, i.e. Compose's sense (no flip, unlike AppKit). The contacts carry `TaoTrackpadRotationContacts` ids, which is how `TitleBar` keeps them from arming a window drag on every platform (a Linux rotation over the bar started a compositor move). An interrupted rotation calls `cancelPointerInput()` **before** sending the contacts' Release — the other order delivers an unconsumed touch-up, i.e. a tap. Linux headful coverage: `LinuxTrackpadPinchHeadfulCases` (synthetic `GdkEventTouchpadPinch` through the GtkWindow's `event` signal via `nativeLinuxInjectGdkTouchpadPinch`; coordinates are toplevel-relative, so add `nativeLinuxContentOrigin`) and `TrackpadScaleHeadfulCases` (real Ctrl+wheel through the AWT Robot — X11 leg only, the Robot cannot inject on Wayland). - macOS Liquid Glass enabled by default via `macOsSdkVersion = "26.0"` (vtool SDK patching) +- **Windows NSIS hot update** (every NSIS installer of a JVM app, no DSL switch; per-user installs only — a non-writable `Program Files` install falls back to the classic update): the app never leaves the screen while it updates. `WindowsHotUpdateLayout` lays the jpackage image out as `.exe` + `app\.cfg` at the root and `versions\\{app,runtime}` — the `.cfg` names the runtime with `app.runtime=$ROOTDIR\versions\\runtime` and every `$APPDIR` becomes `$ROOTDIR\versions\\app` (the jpackage launcher reads nothing else, from JDK 21 at least). `installAndRestart` (`WindowsHotUpdate`) then returns immediately: it renames the running launcher(s) to `*.nucleus-old` (a running exe can be renamed, not overwritten) and copies each back, writable (jpackage ships it read-only) — the copy is mapped by nobody, so the installer can replace it while shortcuts, the Run key and protocol handlers keep working — then runs the installer **while the app runs** with `NUCLEUS_HOT_UPDATE=1` — `WindowsHotUpdateNsis`'s `customCheckAppRunning` skips electron-builder's kill and the old version's `customRemoveFiles` keeps its files (both reproduce the 26.x template bodies otherwise; the env reaches the old uninstaller because the installer's `ExecWait` inherits it) — reads the installed version back from `app.runtime`, releases the single-instance lock (`SingleInstanceManager.releaseForHandoff`), launches the new version with `NUCLEUS_UPDATE_READY_FILE` / `NUCLEUS_UPDATE_PREVIOUS_PID`, and exits once the file appears. `UpdateHandoff.signalReady()` writes it from `TaoWindow`'s first presented frame after `show()`, then deletes retired versions (rename-then-delete: a version still in use cannot be renamed) and launchers — **jpackage ships the launcher read-only**, clear the flag before deleting. The previous PIDs include the launcher parent: jpackage's Windows launcher restarts itself as a child (skipped when inherited env says it already did). If the hot path cannot start it falls back to the classic update; if the **installer** fails the app just keeps running (the classic path would rerun the same failing installer and close/reopen the app at every check). **Multi-instance (Chromium's model)**: installs are serialized by an exclusive lock on `versions\.nucleus-install.lock` (Chromium's single machine-wide updater); an instance that waited, or finds the `.cfg` already starting a newer version, only hands off. Other instances learn about it locally — `NucleusUpdater.pendingRestartVersion` (`InstalledVersionWatcher`: `WatchService` on `app\` + 30 min poll, read under the **shared** lock because the `.cfg` is written before its version finishes extracting; Chromium's `InstalledVersionMonitor` + `InstalledVersionPoller`) — and `checkForUpdates` returns `NotAvailable` for a version already on disk, so nothing is downloaded twice. Nothing restarts on its own (unsaved work): the app offers it and calls `restartToInstalledVersion(relaunchArguments)`. `relaunchArguments` (`installAndRestart(file, args)`, Windows only) is explicit and empty by default — replaying the original command line would resend the autostart marker (the new version would think it started at login) or a deep link; Chromium drops positional args too. A same-JVM lock through another channel is an `OverlappingFileLockException`, not a wait: `withInstallLock` retries it. A PowerShell guard relaunches the app if a non-hot installer closed it anyway — unless the user quit it (a shutdown hook drops `app-exited`; a killed process runs none). PowerShell scripts are written with a UTF-8 **BOM** (`writePowerShellScript`): Windows PowerShell 5.1 reads BOM-less scripts as ANSI, which broke every update — classic included — for accented profile paths (`C:\Users\Hélène\…`). The "just updated" marker is written before the install, so `consumeUpdateEvent` / `wasJustUpdated` only report it when its target is the running version (a failed install used to announce an update that never happened). `-Dnucleus.updater.hotUpdate.disabled=true` forces classic. GraalVM native images have no `.cfg` indirection and stay classic (would need a stub launcher). E2E: `scripts/windows-hot-update-e2e.ps1` + `examples/hot-update-demo` (samples visible windows and the screen pixel every ~18 ms; measured 0 ms gap hot vs ~13-15 s classic). `-Scenario` covers `update`, `relaunch-during-install`, `close-during-install`, `failing-installer`, `stale-target-dir`, `two-instances`, `notify-other-instance`; `-NewVersion a,b` chains updates; `-InstallDir` with spaces/apostrophe/accents; a flat (pre-hot) old installer checks the migration (first hop classic, then hot). The window manager cross-fades windows, so blends of the two versions' colours are not gaps. The screen check is meaningless while the display is off — the capture freezes and nothing composes - **PKG has two channels**, chosen by `macOS { pkg { appStore } }` (default `true`); whether `TargetFormat.Pkg` is a store format is `JvmApplicationDistributions.isSandboxed(format)`, not an enum property. App Store PKG = sandboxed pipeline, "3rd Party Mac Developer" certificates, `productsign` after the build, never notarized (Transporter upload). `appStore = false` = Developer ID PKG on the DMG pipeline (#249): electron-builder signs the installer itself from `pkg.identity` = the **bare** `NAME (TEAMID)` (it prepends "Developer ID Installer" and rejects a prefixed qualifier; `CSC_IDENTITY_AUTO_DISCOVERY=false` means no identity ⇒ silently unsigned, which the task catches with `pkgutil --check-signature`), a DSL keychain travels as `CSC_KEYCHAIN`, and `notarizePkg` notarizes the `.pkg`. `pkg { preInstall / postInstall }` are staged in `/build/pkg-scripts` for `pkgbuild --scripts` (shebang required); the App Store rejects install scripts (error 90254), so they require `appStore = false`. **The staged `preinstall` / `postinstall` are Nucleus shims, not the app's script**: electron-builder sets `BundlePre/PostInstallScriptPath` *and* passes `--scripts`, so `PackageInfo` declares each script twice and Installer runs it twice (confirmed on a real install). The shim skips the per-bundle pass (`$2` is the `.app`) and execs the app's copy, staged as `nucleus-app-pre` / `nucleus-app-post` — names electron-builder's `name.includes("preinstall")` scan must not match. Runtime: gate sandbox-sensitive features on `ExecutableRuntime.isSandboxed()` (`APP_SANDBOX_CONTAINER_ID`), never on `isPkg()` — that is also what makes a Developer ID PKG self-updatable (`NucleusUpdater.isUpdateSupported`) while the App Store build stays excluded - **Node.js is provisioned, not required**: every format except `TargetFormat.RawAppImage` is built by electron-builder, which the plugin installs with `npm ci --ignore-scripts` against an embedded lock file — so packaging needs a Node.js. It downloads one from `nodejs.org` (verified against the release's `SHASUMS256.txt`) into `/nucleus/nodejs`, exactly like the GraalVM and packaging JDK toolchains, and the three share `ToolchainDownloads`. Configure with `nativeDistributions { nodejs { autoDownload / version / installDir } }`; `version` is a major line (`"22"`, the default), `"lts"`, or a pinned release, and a floating line is sticky once downloaded. Precedence: the `compose.electronBuilder.nodePath` Gradle property, then `NUCLEUS_NODE_HOME`, then the provisioned install, then `PATH` (also the fallback when the download fails). CI therefore runs **no** `actions/setup-node` — only a cache of `~/.gradle/nucleus/nodejs`. `release-desktop`'s `universal-macos` job runs electron-builder outside the plugin, so `build-macos-universal/provision-electron-builder.sh` mirrors it: same Node resolution rule, same install layout and marker (the cache entry is shared), and `npm ci --ignore-scripts` against the plugin's embedded lock file — never `npx --yes` - The HotSpot GC is selected type-safely with `application { garbageCollector = GarbageCollector.Z }` (unset = JVM ergonomics). The flags are prepended to the launcher `.cfg` java-options and to the `run` task — before `jvmArgs`, so an explicit `-XX:+Use…GC` there still wins — and the AOT training run inherits them from the `.cfg` diff --git a/core-runtime/api/core-runtime.api b/core-runtime/api/core-runtime.api index 798509f4c..14f8c4780 100644 --- a/core-runtime/api/core-runtime.api +++ b/core-runtime/api/core-runtime.api @@ -148,6 +148,7 @@ public final class dev/nucleusframework/core/runtime/SingleInstanceManager { public final fun getConfiguration ()Ldev/nucleusframework/core/runtime/SingleInstanceManager$Configuration; public final fun isSingleInstance (Lkotlin/jvm/functions/Function1;Lkotlin/jvm/functions/Function1;)Z public static synthetic fun isSingleInstance$default (Ldev/nucleusframework/core/runtime/SingleInstanceManager;Lkotlin/jvm/functions/Function1;Lkotlin/jvm/functions/Function1;ILjava/lang/Object;)Z + public final fun releaseForHandoff ()V public final fun setConfiguration (Ldev/nucleusframework/core/runtime/SingleInstanceManager$Configuration;)V } @@ -170,6 +171,27 @@ public final class dev/nucleusframework/core/runtime/SingleInstanceManager$Confi public fun toString ()Ljava/lang/String; } +public final class dev/nucleusframework/core/runtime/UpdateHandoff { + public static final field ENV_HOT_INSTALL Ljava/lang/String; + public static final field ENV_PREVIOUS_PID Ljava/lang/String; + public static final field ENV_READY_FILE Ljava/lang/String; + public static final field INSTANCE Ldev/nucleusframework/core/runtime/UpdateHandoff; + public static final field RETIRED_LAUNCHER_SUFFIX Ljava/lang/String; + public static final field VERSIONS_DIR_NAME Ljava/lang/String; + public static final fun cleanupRetiredVersions ()V + public static final fun getVersionedInstall ()Ldev/nucleusframework/core/runtime/VersionedInstall; + public static final fun isHandoffLaunch ()Z + public static final fun signalReady ()V +} + +public final class dev/nucleusframework/core/runtime/VersionedInstall { + public fun (Ljava/io/File;Ljava/io/File;Ljava/io/File;)V + public final fun getLauncher ()Ljava/io/File; + public final fun getRoot ()Ljava/io/File; + public final fun getVersionDir ()Ljava/io/File; + public final fun getVersionsDir ()Ljava/io/File; +} + public final class dev/nucleusframework/core/runtime/WindowBackend : java/lang/Enum { public static final field Awt Ldev/nucleusframework/core/runtime/WindowBackend; public static final field Companion Ldev/nucleusframework/core/runtime/WindowBackend$Companion; diff --git a/core-runtime/src/main/kotlin/dev/nucleusframework/core/runtime/SingleInstanceManager.kt b/core-runtime/src/main/kotlin/dev/nucleusframework/core/runtime/SingleInstanceManager.kt index 302e0db33..abe6f71c2 100644 --- a/core-runtime/src/main/kotlin/dev/nucleusframework/core/runtime/SingleInstanceManager.kt +++ b/core-runtime/src/main/kotlin/dev/nucleusframework/core/runtime/SingleInstanceManager.kt @@ -59,6 +59,9 @@ public object SingleInstanceManager { private var fileLock: FileLock? = null private var isWatching = false + @Volatile + private var handedOff = false + /** * Checks if the current process is the single running instance. * @@ -112,6 +115,8 @@ public object SingleInstanceManager { } Runtime.getRuntime().addShutdownHook( Thread { + // After a handoff the lock file belongs to the new instance. + if (handedOff) return@Thread releaseLock() lockFile.delete() deleteRestoreRequestFile() @@ -175,7 +180,7 @@ public object SingleInstanceManager { continue } val filename = event.context() as Path - if (filename.toString() == configuration.restoreRequestFileName) { + if (!handedOff && filename.toString() == configuration.restoreRequestFileName) { debugLog { "Restore request file detected" } configuration.restoreRequestFilePath.onRestoreRequest() // Remove the request file after processing @@ -225,6 +230,21 @@ public object SingleInstanceManager { } } + /** + * Gives up the lock while this process keeps running, so the instance it is about to launch + * becomes the single instance — the seamless restart after a hot update, where the old version + * stays on screen until the new one is.

Do not treat `IDEAL_API.md - **macOS trackpad on Tao** (#652–#654, #660): scroll deltas are AWT-shaped (`preciseWheelRotation`, no display scale). Trackpad two-finger swipe reaches Compose as `PanStart` / `PanMove` / `PanEnd` (`panOffset` = AWT delta × 10 dp), wheel notches as `Scroll`; foundation's `Modifier.scrollable` handles both. Custom handlers that only listen for `PointerEventType.Scroll` must also handle Pan, or the app can set `-Dnucleus.tao.trackpadPanEvents=false` to get AWT-style `Scroll` for everything. Everything scroll-related enters the scene through `TaoSceneScrollRouter` (window + NSPanel popups); the phase wire (Rust `SCROLL_GESTURE_*`, `popup_panel.m`, `TaoScrollGesturePhase`) is guarded by `TaoScrollWireDriftTest`. Platform-recognized pinch is `ScaleStart` / `ScaleChange` / `ScaleEnd` (`scaleFactor` = per-event ratio) via `dispatchTrackpadScale` — not two synthetic Touch contacts; `Modifier.transformable` and MapLibre consume that path, while `detectTransformGestures` still only sees two-finger rotate (two synthetic Touch contacts). Magnify and rotate interleave on a real trackpad and the two models cannot overlap (a Scale event without the contacts reads as their release → a touch tap per step; one carrying them stamps the factor on every pointer and foundation multiplies it per pointer), so the gesture that begins first owns it: during a pinch rotate steps are dropped, during a rotation magnify widens the contacts (spacing clamped to 0.05–20×, past which `detectZoom` handed the app `Infinity` / `NaN`). The contacts never coexist with **any** mouse-only event: a rotation does not start while a pan is open (`TaoSceneScrollRouter.panOpen`), drops trackpad scroll and smart-magnify while it owns the fingers, and a real cursor move / click / exit / focus loss interrupts it (cancelled, not a tap; the rest of it is ignored until it ends). Headful coverage: `MacOsTrackpadGestureMonkeyHeadfulCases` (trackpad / chaos / burst profiles × seeds against an exact oracle of the host rules, plus degenerate cases: collapsing / exploding contacts, gestures far off-window, a window closed with 200 gestures queued) and `MacOsTrackpadScaleHeadfulCases` (gesture NSEvents via `nativeDiagInjectTrackpadGesture` — a type-29 CGEvent, window set through field 51 + the private `CGEventSetWindowLocation`, **posted** with `postEvent:atStart:`: a synchronous `sendEvent:` from the test body re-enters tao's event callback and deadlocks). Linux/Windows pinch (GDK / Ctrl+wheel) uses the same Scale events. **GDK differs**: it reports pinch and rotation as *one* gesture (every `GdkEventTouchpadPinch` carries a scale and an angle, `touch.rs` forwards a magnify then a rotate step for each), so first-come would make rotation unreachable — a pinch opens as Scale and only accumulates its angle, and the rotation takes over (Scale closes, contacts pressed already turned by that angle) once it has turned 10° while the zoom stays within ±10 %. GDK's `angle_delta` is clockwise-positive on screen, i.e. Compose's sense (no flip, unlike AppKit). The contacts carry `TaoTrackpadRotationContacts` ids, which is how `TitleBar` keeps them from arming a window drag on every platform (a Linux rotation over the bar started a compositor move). An interrupted rotation calls `cancelPointerInput()` **before** sending the contacts' Release — the other order delivers an unconsumed touch-up, i.e. a tap. Linux headful coverage: `LinuxTrackpadPinchHeadfulCases` (synthetic `GdkEventTouchpadPinch` through the GtkWindow's `event` signal via `nativeLinuxInjectGdkTouchpadPinch`; coordinates are toplevel-relative, so add `nativeLinuxContentOrigin`) and `TrackpadScaleHeadfulCases` (real Ctrl+wheel through the AWT Robot — X11 leg only, the Robot cannot inject on Wayland). - macOS Liquid Glass enabled by default via `macOsSdkVersion = "26.0"` (vtool SDK patching) - **Windows NSIS hot update** (every NSIS installer of a JVM app, no DSL switch; per-user installs only — a non-writable `Program Files` install falls back to the classic update): the app never leaves the screen while it updates. `WindowsHotUpdateLayout` lays the jpackage image out as `.exe` + `app\.cfg` at the root and `versions\\{app,runtime}` — the `.cfg` names the runtime with `app.runtime=$ROOTDIR\versions\\runtime` and every `$APPDIR` becomes `$ROOTDIR\versions\\app` (the jpackage launcher reads nothing else, from JDK 21 at least). `installAndRestart` (`WindowsHotUpdate`) then returns immediately: it renames the running launcher(s) to `*.nucleus-old` (a running exe can be renamed, not overwritten) and copies each back, writable (jpackage ships it read-only) — the copy is mapped by nobody, so the installer can replace it while shortcuts, the Run key and protocol handlers keep working — then runs the installer **while the app runs** with `NUCLEUS_HOT_UPDATE=1` — `WindowsHotUpdateNsis`'s `customCheckAppRunning` skips electron-builder's kill and the old version's `customRemoveFiles` keeps its files (both reproduce the 26.x template bodies otherwise; the env reaches the old uninstaller because the installer's `ExecWait` inherits it) — reads the installed version back from `app.runtime`, releases the single-instance lock (`SingleInstanceManager.releaseForHandoff`), launches the new version with `NUCLEUS_UPDATE_READY_FILE` / `NUCLEUS_UPDATE_PREVIOUS_PID`, and exits once the file appears. `UpdateHandoff.signalReady()` writes it from `TaoWindow`'s first presented frame after `show()`, then deletes retired versions (rename-then-delete: a version still in use cannot be renamed) and launchers — **jpackage ships the launcher read-only**, clear the flag before deleting. The previous PIDs include the launcher parent: jpackage's Windows launcher restarts itself as a child (skipped when inherited env says it already did). If the hot path cannot start it falls back to the classic update; if the **installer** fails the app just keeps running (the classic path would rerun the same failing installer and close/reopen the app at every check). **Multi-instance (Chromium's model)**: installs are serialized by an exclusive lock on `versions\.nucleus-install.lock` (Chromium's single machine-wide updater); an instance that waited, or finds the `.cfg` already starting a newer version, only hands off. Other instances learn about it locally — `NucleusUpdater.pendingRestartVersion` (`InstalledVersionWatcher`: `WatchService` on `app\` + 30 min poll, read under the **shared** lock because the `.cfg` is written before its version finishes extracting; Chromium's `InstalledVersionMonitor` + `InstalledVersionPoller`) — and `checkForUpdates` returns `NotAvailable` for a version already on disk, so nothing is downloaded twice. Nothing restarts on its own (unsaved work): the app offers it and calls `restartToInstalledVersion(relaunchArguments)`. `relaunchArguments` (`installAndRestart(file, args)`, Windows only) is explicit and empty by default — replaying the original command line would resend the autostart marker (the new version would think it started at login) or a deep link; Chromium drops positional args too. A same-JVM lock through another channel is an `OverlappingFileLockException`, not a wait: `withInstallLock` retries it. A PowerShell guard relaunches the app if a non-hot installer closed it anyway — unless the user quit it (a shutdown hook drops `app-exited`; a killed process runs none). PowerShell scripts are written with a UTF-8 **BOM** (`writePowerShellScript`): Windows PowerShell 5.1 reads BOM-less scripts as ANSI, which broke every update — classic included — for accented profile paths (`C:\Users\Hélène\…`). The "just updated" marker is written before the install, so `consumeUpdateEvent` / `wasJustUpdated` only report it when its target is the running version (a failed install used to announce an update that never happened). `-Dnucleus.updater.hotUpdate.disabled=true` forces classic. GraalVM native images have no `.cfg` indirection and stay classic (would need a stub launcher). E2E: `scripts/windows-hot-update-e2e.ps1` + `examples/hot-update-demo` (samples visible windows and the screen pixel every ~18 ms; measured 0 ms gap hot vs ~13-15 s classic). `-Scenario` covers `update`, `relaunch-during-install`, `close-during-install`, `failing-installer`, `stale-target-dir`, `two-instances`, `notify-other-instance`; `-NewVersion a,b` chains updates; `-InstallDir` with spaces/apostrophe/accents; a flat (pre-hot) old installer checks the migration (first hop classic, then hot). The window manager cross-fades windows, so blends of the two versions' colours are not gaps. The screen check is meaningless while the display is off — the capture freezes and nothing composes +- **Testing updates without publishing** (electron-updater's `dev-app-update.yml` + Squirrel/Velopack local sources, plus a simulation and a fault-injecting host none of them ship): three switches, all read as a system property *or* the matching environment variable (`UpdaterSettings`: `nucleus.updater.feedUrl` ↔ `NUCLEUS_UPDATER_FEED_URL`, camel humps become `_`), which `./gradlew run -Pnucleus.updater.…` forwards as `-D` and `runDistributable` as env. (1) **Feed redirect** `nucleus.updater.feedUrl` (`FeedOverride`) replaces the configured provider with `LocalFileProvider` (a path or `file:` URL — `FeedFetcher` reads `file:` URLs; no differential, ranges need HTTP) or `GenericProvider` (`https`, loopback `http` only — `[::1]` is `URI.host` *with* brackets). (2) **Simulation** `nucleus.updater.simulate=>` (+ `.version`, `.duration`, `.size`, `.differential`, `.justUpdatedFrom`), or `UpdaterConfig.simulation` in code (wins over both switches): `SimulatedUpdate` answers the check, times the progress, throws the real exceptions, and the install is skipped. (3) **Installed apps honour (1) and the launch-time (2) only with `UpdaterConfig.allowLaunchOverrides`** — whoever sets the variable would choose what the app installs, or silence its updates; an unpackaged run (`ExecutableType.DEV`) always does. Ignored switches log a warning, applied ones too. `NucleusUpdater.feedOverride` / `.simulation` expose what applies. **An unpackaged run never installs**: `installAndRestart` / `installAndQuit` log and return (the installer would install a copy beside the IDE run and exit it), and its format is `null` (auto) — `FileSelector` has no `dev` format. Plugin: `serveUpdateFeed` (`AbstractServeUpdateFeedTask`, per build type, registered when the current OS has an auto-updatable format) depends on the packaging tasks and serves `UpdateYmlPublish.discoverAndMerge` of their outputs + the artifacts with ranges on `127.0.0.1:8421` (`-Pnucleus.updater.serve.{port,throttle,latency,timeout}`). **The packaging output is a feed on its own**: electron-builder writes no `latest*.yml` without a `publish` provider, so the plugin now writes it for every self-contained updatable format (`TargetFormat.updateArtifactExtension`, not NSIS-Web), listing only artifacts named with *this* version (electron-builder never cleans the output dir: a bumped build used to list the previous installer first, i.e. the one every client downloads), and every packaging run first deletes the old manifests (`UpdateYmlPublish.deleteManifests`: a kept `latest.yml` described the previous artifact, SHA-512 included). `updater-testing` (`UpdateFeedServer`: `publish()` writes the manifest, `fault(FeedFault.Status/Delay/Throttle/Truncate/Corrupt/IgnoreRange, path glob, times)`, `requests`) is the host `UpdaterTortureTest` (updater-testing) and `DifferentialTortureTest` (updater-runtime, real electron-builder block maps) run against. A `Truncate` must flush before it drops the connection: bytes left in the server's buffer make the drop look like a stale pooled connection, which the JDK `HttpClient` silently retries. E2E on a real installed NSIS app: `scripts/updater-dev-testing-e2e.ps1` + `examples/hot-update-demo` (production `GitHubProvider`, `allowLaunchOverrides` unless `HOT_UPDATE_DEMO_ALLOW_OVERRIDES=0`) — `file-feed`, `file-url-feed` (spaces + non-ASCII), `http-feed` (throttled `serveUpdateFeed`), `http-feed-cached` (differential over the task), `locked`, `simulate`, `simulate-error`, `simulate-updated`, `run-simulate`, `run-feed` - **PKG has two channels**, chosen by `macOS { pkg { appStore } }` (default `true`); whether `TargetFormat.Pkg` is a store format is `JvmApplicationDistributions.isSandboxed(format)`, not an enum property. App Store PKG = sandboxed pipeline, "3rd Party Mac Developer" certificates, `productsign` after the build, never notarized (Transporter upload). `appStore = false` = Developer ID PKG on the DMG pipeline (#249): electron-builder signs the installer itself from `pkg.identity` = the **bare** `NAME (TEAMID)` (it prepends "Developer ID Installer" and rejects a prefixed qualifier; `CSC_IDENTITY_AUTO_DISCOVERY=false` means no identity ⇒ silently unsigned, which the task catches with `pkgutil --check-signature`), a DSL keychain travels as `CSC_KEYCHAIN`, and `notarizePkg` notarizes the `.pkg`. `pkg { preInstall / postInstall }` are staged in `/build/pkg-scripts` for `pkgbuild --scripts` (shebang required); the App Store rejects install scripts (error 90254), so they require `appStore = false`. **The staged `preinstall` / `postinstall` are Nucleus shims, not the app's script**: electron-builder sets `BundlePre/PostInstallScriptPath` *and* passes `--scripts`, so `PackageInfo` declares each script twice and Installer runs it twice (confirmed on a real install). The shim skips the per-bundle pass (`$2` is the `.app`) and execs the app's copy, staged as `nucleus-app-pre` / `nucleus-app-post` — names electron-builder's `name.includes("preinstall")` scan must not match. Runtime: gate sandbox-sensitive features on `ExecutableRuntime.isSandboxed()` (`APP_SANDBOX_CONTAINER_ID`), never on `isPkg()` — that is also what makes a Developer ID PKG self-updatable (`NucleusUpdater.isUpdateSupported`) while the App Store build stays excluded - **Node.js is provisioned, not required**: every format except `TargetFormat.RawAppImage` is built by electron-builder, which the plugin installs with `npm ci --ignore-scripts` against an embedded lock file — so packaging needs a Node.js. It downloads one from `nodejs.org` (verified against the release's `SHASUMS256.txt`) into `/nucleus/nodejs`, exactly like the GraalVM and packaging JDK toolchains, and the three share `ToolchainDownloads`. Configure with `nativeDistributions { nodejs { autoDownload / version / installDir } }`; `version` is a major line (`"22"`, the default), `"lts"`, or a pinned release, and a floating line is sticky once downloaded. Precedence: the `compose.electronBuilder.nodePath` Gradle property, then `NUCLEUS_NODE_HOME`, then the provisioned install, then `PATH` (also the fallback when the download fails). CI therefore runs **no** `actions/setup-node` — only a cache of `~/.gradle/nucleus/nodejs`. `release-desktop`'s `universal-macos` job runs electron-builder outside the plugin, so `build-macos-universal/provision-electron-builder.sh` mirrors it: same Node resolution rule, same install layout and marker (the cache entry is shared), and `npm ci --ignore-scripts` against the plugin's embedded lock file — never `npx --yes` - The HotSpot GC is selected type-safely with `application { garbageCollector = GarbageCollector.Z }` (unset = JVM ergonomics). The flags are prepended to the launcher `.cfg` java-options and to the `run` task — before `jvmArgs`, so an explicit `-XX:+Use…GC` there still wins — and the AOT training run inherits them from the `.cfg` diff --git a/examples/hot-update-demo/src/main/kotlin/hotupdatedemo/Main.kt b/examples/hot-update-demo/src/main/kotlin/hotupdatedemo/Main.kt index 7def2c7b7..1c1d319e4 100644 --- a/examples/hot-update-demo/src/main/kotlin/hotupdatedemo/Main.kt +++ b/examples/hot-update-demo/src/main/kotlin/hotupdatedemo/Main.kt @@ -23,18 +23,24 @@ import dev.nucleusframework.application.DecoratedWindow import dev.nucleusframework.application.nucleusApplication import dev.nucleusframework.updater.NucleusUpdater import dev.nucleusframework.updater.UpdateResult +import dev.nucleusframework.updater.exception.UpdateException import dev.nucleusframework.updater.provider.GenericProvider +import dev.nucleusframework.updater.provider.GitHubProvider import dev.nucleusframework.window.NucleusDecoratedWindowTheme import dev.nucleusframework.window.TitleBar import kotlinx.coroutines.delay import kotlinx.coroutines.flow.first import kotlinx.coroutines.flow.last +import kotlinx.coroutines.flow.onEach import java.io.File import java.time.LocalTime import kotlin.time.Duration.Companion.seconds private val feed: String?

When two JARs define the same classes, the packaged app therefore loaded whichever sorted first, while ./gradlew run follows the runtime-classpath order.

The launcher .cfg classpath is now rewritten in classpath order right after jpackage, before macOS signing and the Linux pathing-jar collapse.
