For launches where the person chose the plugin, and their restarts and restores, CanvasTTY asks the service to prepare the launch and adds its environment variables, secret variables resolved from the plugin's own secrets (masked in text other agents and the control CLI read), arguments and per-run files. Contributors merge in plugin-id order; a refusal, a 5 s timeout, a conflict, a reserved name or an approval/conversation argument refuses the launch with the reason on the card, and a restored card whose plugin is unavailable comes back stopped. The chosen values are saved with the session. A contributor may also declare `launch.policy`: it is then asked before every launch of its agents where the person did not choose it (`chosen: false`), may only refuse, and no answer refuses too. Examples: `examples/plugins/launch-env`, `examples/plugins/yolo-guard` (a launch policy). - Added session environments (`environment:provide`): a trusted plugin service can offer places a card runs in (a git worktree, a container, a remote host), chosen under **Where** in the launcher's Advanced section; terminals get the same launcher while such an environment applies to them. The service prepares the place once, then wraps every start (validated: an absolute program path or a bare name resolved on PATH, never a shell string; launch-contributor env rules; plugin secrets masked) while CanvasTTY keeps spawning the PTY. The opaque ref is saved with the card; restore resumes environments first, then parents before children, and a missing, disabled or untrusted plugin, a stopped environment or a timeout brings the card back stopped with the reason, never run locally. Closing such a card asks once "Keep environment data?" and releases it accordingly. Launch contributors and policies are told the card's environment (`environment` in `canvastty.launch.prepare`). Example: `examples/plugins/env-worktree` (one git worktree per card). - Added base protection and decision hooks. Base protection (Settings → Agents, on by default, the person can turn it off) refuses, before a local Claude Code, Codex, Qwen Code or OpenCode tool call runs (YOLO included), sudo and other elevation, curl | sh and download-and-run, disk and format commands, fork bombs, and writes or deletes outside the working folder (`/tmp` and the home folder included, and deleting the folder itself; the agent's own plan and memory folders excepted), telling the model what to do instead. A trusted plugin service can declare `decide` (`decision:provide`) and answer `canvastty.decide` with deny, ask or allow: base protection runs first, any deny wins, a timeout or error asks the person, and an allow counts only after a separate **May allow agent actions** confirmation. A service may declare `decide.timeoutMs` (1–60 s, 3 s by default): CanvasTTY waits that long, tells the service its `budgetMs`, and sizes each card's hook, helper and gateway deadlines at launch for the longest budget that applies (the default keeps today's deadlines). Example: `examples/plugins/deny-rm`. Every text one agent reads from another (`observe_agent`, `get_agent_result`, the control CLI's screen, result and failure details) is now masked for vault keys, launch secrets, values a service registers (`redaction.register`) or reads (`secrets.get`), keys wrapped over lines, and common key shapes. +- The decision hook now fails closed. While base protection is on or a decision plugin applies, a Claude Code, Codex, Qwen Code or OpenCode shell or file-writing call that CanvasTTY cannot check (the socket is missing or refused, no answer in time, an unreadable answer, the gateway's own failure where the CLI cannot ask, hook input it cannot read) is refused with "CanvasTTY safety check unavailable" instead of running unchecked. With base protection off and no decision plugin nothing changes, and answered calls take no extra time. +- Base protection now reads more command forms: a command after `do`, `then`, `else`, `if`, `while`, `until` or `!`; `env -i`/`-u`/`-C`/`-S`, `stdbuf`, `busybox`/`toybox` applets and `script -c` / `script file cmd`; `perl -i` and `ruby -i` in-place edits; `find -L`/`-H`/`-P`/`-O2`/`-f`; `cp`/`mv`/`install`/`ln -t DIR`; `tar -C DIR -x…` and `--directory=`; `unzip -o … -d DIR`; bundled `curl -fsSLo FILE`, `--output=`, `--output-dir` before or after `-O`/`-o` (a relative `-o` lands in it), the cookie jar, header dump, trace, `--stderr`, `--libcurl`, `--etag-save`, `--hsts`, `--alt-svc` and `-w '%output{FILE}'` files in every spelling, `wget -qO`/`-qP`, its log (`-o`/`-a`/`--output-file`/`--append-output`), `--save-cookies`, `--rejected-log` and `--warc-file`; `-o /dev/null` and `-D -` write no file and are no longer refused. Each is refused outside the project exactly like the plain command, a download run in the same command is download-and-run however its output flag is written, and the same forms inside the project stay allowed (`find -L dir -exec rm {} +` inside the project is no longer refused). - Added plugin agent tools, session events and card badges and actions. A trusted service can offer `tools` (`tools:agents`) that appear in `canvastty_agents` as `__` (dots in the id as `_`, the tool-name shape Anthropic and OpenAI accept) for the session roles they list (orchestrator, agent, subagent; Claude Code, Codex, Qwen Code, OpenCode); calls carry the caller's session id, and answers are masked, capped at 32 K characters and 15 s. A service can subscribe to card events (`sessions:events`: created, restored, status, exited, closed, with folders and the environment ref; the end of the output only with `sessions:read-screen`, masked), start cards through the normal launch pipeline (`sessions:launch`), and type into or close only the cards it started (`sessions:control`; ownership is saved with the card, so it survives a restore). With `cards:decorate` it sets plain-text badges on cards and adds actions to the card menu of matching cards (provider, environment kind, role); the answer shows as a toast on the card. Example: `examples/plugins/collect-demo` (**Show changes** on worktree cards and `collect-demo__diffstat` for orchestrators). - Reworked "Windows after restart" into one "Agent sessions after restart" model: **Don't save**, **Reopen windows** (new conversations), or **Continue conversations** (the old "on" migrates here). Claude Code and OpenCode now resume their own conversation by the id their lifecycle hook reported, as Codex does (`claude --resume`, `opencode --session`); two cards of one CLI in one folder no longer continue the same conversation. Finished agents come back stopped with Restart / Continue instead of rerunning, the card options menu has **Don't restore this card**, and session records (v2, read-compatible with v1) keep no scrollback, prompts or secrets. - Made the agent orchestration endpoint an explicit setting (Settings → Agents → "Agent orchestration endpoint", `agentControlEnabled`, off by default; `--agent-control` / `CANVASTTY_AGENT_CONTROL=1` still force it on for one launch) that starts and stops the endpoint at runtime, and added an **Orchestrator** role to the launch dialog next to the normal/YOLO profile: the session keeps the provider you opened the dialog for, gets `CANVASTTY_CONTROL_CONNECTION` and `CANVASTTY_CONTROL_CLI` in its environment so the bundled CLI works without setup, shows an "Orchestrator" badge, keeps its role across restore, and the dialog offers to enable the endpoint first when it is off instead of enabling anything silently. The endpoint's `create` now accepts every agent provider (`codex, claude, qwen, kimi, opencode, hermes, grok, omp, pi`) and reports `capabilities { result, menus }` per worker on `create` and `list`: both are `true` for Codex only; other providers' `screen` has no menu interaction, `choose`/`dismiss` fail with `NOT_SUPPORTED`, `send` relies on the idle status alone, and `result` completes as `no_result`. @@ -28,7 +30,8 @@ - Added a HOME attention queue of sessions that need approval or have failed, derived only from session snapshots, always rendering its title row and an explicit empty state; clicking a row focuses that session. Failure details (trigger, popover, copy) were extracted into one shared implementation used by both the queue and the existing session rows. - Added an attention ring on cards whose session needs approval or has failed, plus the “Notify when attention is needed” setting in Settings → General (on by default) that raises one OS notification on a genuine transition into needing approval or failing: repeated snapshots and already-seen restore-time failures stay silent, and a failure the user triggers by restarting also notifies. Toggling the setting persists. - Cards now report whether they render live output: those in semantic summary mode (zoom below 0.5) stop receiving streamed output while their scrollback stays canonical and complete within the bounded history, and the missed output is replayed once when the card becomes visible again; if more output was produced while hidden than the bounded history holds, the oldest part of that stretch is gone and the replay says so instead of pretending the output is continuous. -- Limited WebGL to the focused terminal card: one context at a time, disposed when focus leaves, with a fallback to the DOM renderer when the context is lost. Palette and transparency rendering are unchanged. +- Terminal cards on screen draw with WebGL from a pool of 10 contexts (Chromium allows 16 per renderer process): the focused card first, then the cards covering the most screen, then the most recently used. Cards that leave the screen, zoom above 1× or go to summary mode give their context back, and changes from panning or zooming wait until the camera is still, so moving around does not rebuild contexts. Every other card keeps the DOM renderer, and a card whose context is lost falls back to it with its contents intact and stays there for a while. Palette and transparency rendering are unchanged. +- Panning the canvas with the wheel or trackpad now moves the already drawn scene on the compositor, as dragging it already did, instead of repainting every card on each frame; the scene is re-rasterized once the gesture stops. - Added a self-update section in Settings → Updates with the honest states: idle, checking, update available with the version, downloading with the percent when known, ready to install, and unavailable for dev, offline, or error. Downloading and installing are explicit user actions, install-and-restart is offered only once the update is downloaded, and in development the row reports unavailable instead of throwing. - Hardened the repository secret audit to ignore key prefixes embedded inside identifiers, so names such as `disk-…` or `task-…` no longer produce false positives while real keys still match. - Added Cursor, MiniMax Code, Devin and Antigravity agents (PR #63). diff --git a/CHANGELOG.ru.md b/CHANGELOG.ru.md index 8c0833d2..514e150b 100644 --- a/CHANGELOG.ru.md +++ b/CHANGELOG.ru.md @@ -10,6 +10,8 @@ - Добавлены launch contributors (`launch:contribute`): доверенный сервис плагина может объявить параметры запуска (флажок, список, текст), которые показываются в разделе **Дополнительно** окна запуска агента. Для запусков, где человек выбрал плагин, а также их перезапусков и восстановления, CanvasTTY просит сервис подготовить запуск и добавляет его переменные окружения, секретные переменные из собственных секретов плагина (маскируются в тексте, который читают другие агенты и control CLI), аргументы и файлы на время запуска. Вклады объединяются в порядке id плагинов; отказ, таймаут 5 с, конфликт, зарезервированное имя или аргумент подтверждений/выбора разговора отклоняют запуск с причиной в окне, а восстановленное окно с недоступным плагином возвращается остановленным. Выбранные значения сохраняются с сессией. Contributor может также объявить `launch.policy`: тогда его спрашивают и перед каждым запуском его агентов, где человек его не выбрал (`chosen: false`); он может только отказать, а отсутствие ответа тоже отказ. Примеры: `examples/plugins/launch-env`, `examples/plugins/yolo-guard` (политика запуска). - Добавлены среды сессий (`environment:provide`): доверенный сервис плагина может предлагать места, где работает окно (git worktree, контейнер, удалённый хост); их выбирают в **Где запустить** в разделе «Дополнительно» лаунчера, а терминал получает тот же лаунчер, пока такая среда к нему применима. Сервис один раз готовит место и оборачивает каждый запуск (с проверкой: абсолютный путь к программе или простое имя из PATH, никогда строка оболочки; правила окружения launch contributors; секреты плагина маскируются), а PTY по-прежнему создаёт CanvasTTY. Непрозрачная ссылка хранится с окном; восстановление сначала возобновляет среды, затем родителей, потом дочерние окна, а отсутствующий, выключенный или недоверенный плагин, остановленная среда или таймаут возвращают окно остановленным с причиной, без локального запуска. При закрытии такого окна один раз спрашивается «Сохранить данные среды?», и среда освобождается по ответу. Launch contributors и политики запуска получают среду окна (`environment` в `canvastty.launch.prepare`). Пример: `examples/plugins/env-worktree` (git worktree на каждое окно). - Добавлены базовая защита и хуки решений. Базовая защита (Настройки → Агенты, включена по умолчанию, человек может её выключить) до выполнения вызова инструмента локальным Claude Code, Codex, Qwen Code или OpenCode (включая YOLO) запрещает sudo и другое повышение прав, curl | sh и запуск скачанного, команды для дисков и форматирования, форк-бомбы, а также запись и удаление вне рабочей папки (включая `/tmp`, домашнюю папку и удаление самой папки; кроме собственных папок планов и памяти агента) и говорит модели, что сделать вместо этого. Доверенный сервис плагина может объявить `decide` (`decision:provide`) и отвечать на `canvastty.decide` запретом, вопросом или разрешением: базовая защита работает первой, любой запрет побеждает, таймаут или ошибка спрашивают человека, а разрешение учитывается только после отдельного подтверждения **Может разрешать действия агентов**. Сервис может объявить `decide.timeoutMs` (1–60 с, по умолчанию 3 с): CanvasTTY ждёт столько, сообщает сервису его `budgetMs` и при запуске настраивает сроки хука, помощника и шлюза каждого окна под самый долгий действующий бюджет (по умолчанию сроки прежние). Пример: `examples/plugins/deny-rm`. Весь текст, который один агент читает у другого (`observe_agent`, `get_agent_result`, экран, результат и детали ошибки в control CLI), теперь маскируется: ключи из хранилища, секреты запуска, значения, зарегистрированные (`redaction.register`) или прочитанные (`secrets.get`) сервисом, ключи, перенесённые на несколько строк, и типичные формы ключей. +- Хук решений теперь закрывается при сбое. Пока включена базовая защита или действует плагин решений, вызов оболочки или записи файла в Claude Code, Codex, Qwen Code или OpenCode, который CanvasTTY не может проверить (сокета нет или соединение отклонено, ответ не пришёл вовремя, ответ не читается, сбой самого шлюза там, где CLI не умеет спрашивать, вход хука не читается), отклоняется с сообщением «CanvasTTY safety check unavailable», а не выполняется без проверки. При выключенной базовой защите и без плагинов решений ничего не меняется, а вызовы с ответом не становятся медленнее. +- Базовая защита распознаёт больше форм команд: команду после `do`, `then`, `else`, `if`, `while`, `until` или `!`; `env -i`/`-u`/`-C`/`-S`, `stdbuf`, апплеты `busybox`/`toybox` и `script -c` / `script файл команда`; правку на месте `perl -i` и `ruby -i`; `find -L`/`-H`/`-P`/`-O2`/`-f`; `cp`/`mv`/`install`/`ln -t КАТАЛОГ`; `tar -C КАТАЛОГ -x…` и `--directory=`; `unzip -o … -d КАТАЛОГ`; склеенные флаги `curl -fsSLo ФАЙЛ`, `--output=`, `--output-dir` до или после `-O`/`-o` (относительный `-o` попадает в него), файлы cookie, заголовков, трассировки, `--stderr`, `--libcurl`, `--etag-save`, `--hsts`, `--alt-svc` и `-w '%output{ФАЙЛ}'` при любом написании, `wget -qO`/`-qP`, его журнал (`-o`/`-a`/`--output-file`/`--append-output`), `--save-cookies`, `--rejected-log` и `--warc-file`; `-o /dev/null` и `-D -` не пишут файл и больше не отклоняются. Вне проекта каждая такая форма отклоняется так же, как простая команда; загрузка, запущенная в той же команде, считается download-and-run при любом написании флага вывода; те же формы внутри проекта по-прежнему разрешены (`find -L dir -exec rm {} +` внутри проекта больше не отклоняется). - Добавлены инструменты плагинов для агентов, события сессий, метки и действия на окнах. Доверенный сервис может предложить `tools` (`tools:agents`), которые появляются в `canvastty_agents` как `__` (точки в id — `_`, такие имена принимают Anthropic и OpenAI) для указанных ролей сессий (оркестратор, агент, субагент; Claude Code, Codex, Qwen Code, OpenCode); вызовы несут id вызывающей сессии, ответы маскируются и ограничены 32 тыс. символов и 15 с. Сервис может подписаться на события окон (`sessions:events`: created, restored, status, exited, closed, с папками и ref среды; конец вывода — только с `sessions:read-screen`, замаскированный), запускать окна через обычный конвейер запуска (`sessions:launch`), а вводить текст и закрывать — только окна, которые запустил сам (`sessions:control`; владение сохраняется с окном и переживает восстановление). С `cards:decorate` он ставит текстовые метки на окна и добавляет действия в меню подходящих окон (провайдер, вид среды, роль); ответ показывается уведомлением на окне. Пример: `examples/plugins/collect-demo` (**Show changes** на окнах в worktree и `collect-demo__diffstat` для оркестраторов). - «Окна после перезапуска» стали единой моделью «Сессии агентов после перезапуска»: **Не сохранять**, **Открыть окна** (новые разговоры) или **Продолжить разговоры** (прежнее «включено» переходит сюда). Claude Code и OpenCode теперь, как и Codex, продолжают свой разговор по id, который сообщил их lifecycle hook (`claude --resume`, `opencode --session`); две карточки одного CLI в одной папке больше не продолжают один и тот же разговор. Завершённые агенты возвращаются остановленными с кнопками «Перезапустить» / «Продолжить», в меню карточки есть **Не восстанавливать это окно**, а записи сессий (v2, совместимы с v1 при чтении) не хранят буфер, промпты и секреты. - Эндпоинт оркестрации агентов стал явной настройкой (Настройки → Агенты → «Эндпоинт оркестрации агентов», `agentControlEnabled`, по умолчанию выключен; `--agent-control` / `CANVASTTY_AGENT_CONTROL=1` по-прежнему принудительно включают его на один запуск), которая запускает и останавливает эндпоинт на лету, а в диалог запуска рядом с профилем normal/YOLO добавлена роль **Оркестратор**: сессия сохраняет провайдера, для которого открыт диалог, получает в окружении `CANVASTTY_CONTROL_CONNECTION` и `CANVASTTY_CONTROL_CLI`, чтобы встроенный CLI работал без настройки, показывает бейдж «Оркестратор», сохраняет роль при восстановлении, а при выключенном эндпоинте диалог предлагает сначала включить его, ничего не включая молча. `create` эндпоинта теперь принимает любого провайдера-агента (`codex, claude, qwen, kimi, opencode, hermes, grok, omp, pi`) и в ответах `create` и `list` сообщает `capabilities { result, menus }` для каждого воркера: оба значения `true` только для Codex; у остальных провайдеров `screen` не содержит взаимодействия с меню, `choose`/`dismiss` завершаются ошибкой `NOT_SUPPORTED`, `send` опирается только на статус idle, а `result` завершается как `no_result`. @@ -28,7 +30,8 @@ - Добавлена очередь внимания в HOME: сессии, которым нужно подтверждение, и завершившиеся с ошибкой, выводятся только из session snapshots; строка заголовка и явное пустое состояние отображаются всегда, а клик по строке фокусирует эту сессию. Детали ошибки (триггер, popover, копирование) вынесены в одну общую реализацию, которую используют и очередь, и прежние строки сессий. - Добавлено кольцо внимания на карточках, чья сессия ждёт подтверждения или завершилась с ошибкой, и настройка «Уведомлять о внимании» в «Настройках → Основные» (включена по умолчанию): она поднимает одно системное уведомление при настоящем переходе в состояние ожидания подтверждения или ошибки: повторные snapshots и уже виденные ошибки при восстановлении остаются молчащими, а ошибка, вызванная пользователем при перезапуске, тоже уведомляет. Переключение настройки сохраняется. - Карточки теперь сообщают, отображают ли они живой вывод: в режиме semantic summary (zoom ниже 0.5) они перестают получать потоковый вывод, а scrollback остаётся каноническим и полным в пределах ограниченной истории; при возврате карточки в видимость пропущенный вывод воспроизводится один раз, а если скрытно было выведено больше, чем вмещает ограниченная история, самая старая часть этого отрезка потеряна, и повтор сообщает об этом вместо того, чтобы выдавать вывод за непрерывный. -- WebGL ограничен сфокусированной карточкой терминала: один контекст одновременно, освобождается при уходе фокуса, при потере контекста используется DOM-renderer. Отрисовка палитры и прозрачности не изменилась. +- Карточки терминала на экране рисуются через WebGL из пула в 10 контекстов (Chromium допускает 16 на процесс renderer): сначала сфокусированная карточка, затем те, что занимают больше места на экране, затем недавно использованные. Карточка, ушедшая за экран, увеличенная больше 1× или перешедшая в режим сводки, отдаёт контекст; при панорамировании и масштабировании пул ждёт, пока камера остановится, поэтому движение по холсту не пересоздаёт контексты. Остальные карточки рисуются DOM-renderer'ом; карточка, потерявшая контекст, возвращается на него без потери содержимого и какое-то время остаётся на нём. Отрисовка палитры и прозрачности не изменилась. +- Панорамирование холста колесом или трекпадом теперь сдвигает уже нарисованную сцену в компоновщике, как это уже было при перетаскивании, а не перерисовывает все карточки на каждом кадре; после остановки жеста сцена растеризуется заново. - В «Настройках → Обновления» появилась строка самообновления с честными состояниями: простой, проверка, доступно обновление (с версией), загрузка (с процентом, когда он известен), готово к установке и недоступно (dev, offline или ошибка). Загрузка и установка — явные действия пользователя, установка с перезапуском предлагается только после загрузки обновления, а в режиме разработки строка сообщает о недоступности и не выбрасывает исключение. - Аудит секретов в репозитории больше не срабатывает на префиксы ключей внутри идентификаторов, поэтому имена вида `disk-…` и `task-…` не дают ложных срабатываний, а настоящие ключи по-прежнему находятся. -

新增会话环境（`environment:provide`）：受信任的插件服务可以提供卡片的运行位置（git worktree、容器、远程主机），在启动器 Advanced 部分的 **Where** 中选择；只要此类环境适用于终端，终端也会使用同一启动器。服务只准备一次运行位置，之后包装每次启动（经过校验：程序的绝对路径或在 PATH 中解析的纯程序名，绝不接受 shell 字符串；遵循启动贡献者的环境变量规则；插件机密被遮蔽），PTY 仍由 CanvasTTY 创建。不透明引用随卡片保存；恢复时先恢复环境，再先父后子启动卡片；插件缺失、被禁用或不受信任、环境已停止或超时时，卡片以停止状态返回并显示原因，绝不在本地运行。关闭此类卡片时只询问一次“Keep environment data?”并据此释放环境。启动贡献者和启动策略会收到卡片的环境（`canvastty.launch.prepare` 中的 `environment`）。示例：`examples/plugins/env-worktree`（每张卡片一个 git worktree）。 - 新增基础保护和决策 hook。基础保护（设置 → Agents，默认开启，用户可以关闭）在本地 Claude Code、Codex、Qwen Code 或 OpenCode 的工具调用运行之前（包括 YOLO）拒绝 sudo 及其他提权、curl | sh 和下载后运行、磁盘与格式化命令、fork 炸弹，以及在工作文件夹之外写入或删除（包括 `/tmp`、主目录和删除文件夹本身；agent 自己的计划和记忆文件夹除外），并告诉模型应当改做什么。受信任的插件服务可以声明 `decide`（`decision:provide`），以拒绝、询问或允许回答 `canvastty.decide`：基础保护最先运行，任何拒绝优先，超时或错误会询问用户，允许只有在单独确认 **May allow agent actions** 之后才算数。服务可以声明 `decide.timeoutMs`（1–60 秒，默认 3 秒）：CanvasTTY 会等待这么久，把 `budgetMs` 告知服务，并在启动时按适用的最长预算设置每张卡片的 hook、helper 和网关期限（默认保持现有期限）。示例：`examples/plugins/deny-rm`。一个 agent 从另一个 agent 读取的所有文本（`observe_agent`、`get_agent_result`、control CLI 的屏幕、结果和失败详情）现在都会遮蔽：密钥库中的密钥、启动机密、服务注册（`redaction.register`）或读取（`secrets.get`）的值、被折行拆开的密钥以及常见密钥形式。 +- 决策 hook 现在在失败时拒绝执行。只要基础保护开启或有决策插件适用，Claude Code、Codex、Qwen Code 或 OpenCode 的 shell 或写文件调用如果 CanvasTTY 无法检查（socket 不存在或连接被拒绝、未及时回答、回答无法解析、CLI 无法询问时网关自身出错、hook 输入无法读取），就会以 “CanvasTTY safety check unavailable” 拒绝，而不是未经检查就运行。基础保护关闭且没有决策插件时行为不变，已得到回答的调用也不会变慢。 +- 基础保护能识别更多命令形式：`do`、`then`、`else`、`if`、`while`、`until` 或 `!` 之后的命令；`env -i`/`-u`/`-C`/`-S`、`stdbuf`、`busybox`/`toybox` applet 以及 `script -c` / `script 文件 命令`；`perl -i` 和 `ruby -i` 原地编辑；`find -L`/`-H`/`-P`/`-O2`/`-f`；`cp`/`mv`/`install`/`ln -t 目录`；`tar -C 目录 -x…` 和 `--directory=`；`unzip -o … -d 目录`；合并写法的 `curl -fsSLo 文件`、`--output=`、位于 `-O`/`-o` 之前或之后的 `--output-dir`（相对的 `-o` 落在其中）、任意写法的 cookie、响应头、跟踪、`--stderr`、`--libcurl`、`--etag-save`、`--hsts`、`--alt-svc` 和 `-w '%output{文件}'` 文件，`wget -qO`/`-qP`、其日志（`-o`/`-a`/`--output-file`/`--append-output`）、`--save-cookies`、`--rejected-log` 和 `--warc-file`；`-o /dev/null` 和 `-D -` 不写文件，不再被拒绝。这些形式在项目外与普通命令一样被拒绝；同一命令中下载后运行，无论输出参数如何书写都算作 download-and-run；项目内的相同形式仍然允许（项目内的 `find -L dir -exec rm {} +` 不再被拒绝）。 - 新增插件 agent 工具、会话事件以及卡片标记和动作。受信任的服务可以提供 `tools`（`tools:agents`），它们以 `__` 的名字（id 中的点写作 `_`，这是 Anthropic 和 OpenAI 接受的工具名形式）出现在 `canvastty_agents` 中，面向其列出的会话角色（编排器、agent、子 agent；Claude Code、Codex、Qwen Code、OpenCode）；调用携带调用方会话 id，回答经过遮蔽，并限制为 32K 字符和 15 s。服务可以订阅卡片事件（`sessions:events`：created、restored、status、exited、closed，包含文件夹和环境 ref；只有具有 `sessions:read-screen` 时才附带经过遮蔽的输出末尾），通过常规启动流程启动卡片（`sessions:launch`），并且只能向自己启动的卡片输入文本或关闭它们（`sessions:control`；所有权随卡片保存，恢复后依然有效）。具有 `cards:decorate` 时，它可以在卡片上设置纯文本标记，并向匹配卡片（服务商、环境类型、角色）的菜单添加动作；回答以提示形式显示在卡片上。示例：`examples/plugins/collect-demo`（worktree 卡片上的 **Show changes** 和供编排器使用的 `collect-demo__diffstat`）。 -

Terminal file drops resolve native `File` objects through preload's `webUtils.getPathForFile`, format paths for the host's default shell, and paste through xterm without submitting. File contents are not read and no new main-process IPC is exposed. - `src/main/ipc/registerIpc.ts` owns native side effects and validates access to persisted media. - `src/main/services/TerminalManager.ts` is the source of truth for live session state and PTY buffers. It keeps scrollback in a bounded chunk buffer and coalesces PTY data into 16ms IPC batches so clear/redraw sequences reach xterm together. A plain terminal starts `idle`; an agent stays `unavailable` until its provider emits a machine-readable lifecycle signal. Codex, Claude Code, Qwen Code, Kimi Code, OpenCode, Hermes, and Grok Build then transition through `idle`, `working`, and `needs_approval` from provider hooks; exact Claude/Qwen OSC 0/2 markers remain a compatibility fallback. Human-readable terminal text and PTY existence are never treated as activity. Process exit provides only `done` or `failed`. An exited PTY may be restarted under the same session ID while preserving its card, bounds, title, and scrollback. Optional restart persistence (Settings → General, "Agent sessions after restart": Don't save / Reopen windows / Continue conversations) writes session records v2 through `TerminalSessionStore`: the card descriptor, the state at quit or exit, the provider conversation id a lifecycle hook reported (`threadId`: Codex thread or Claude session UUID, OpenCode `ses_` id), the per-card restore flag, and two opaque plugin slots (launch options and an environment reference, at most 4 KB each). It never writes PTY scrollback, prompts, child environment, secrets, or capabilities. Plain terminals reopen as fresh shells in their saved folder. +- `src/renderer/src/features/terminal/webglContextPool.ts` decides which terminal cards draw with xterm's WebGL renderer. Chromium keeps at most 16 WebGL contexts per renderer process, so the pool hands out 10: the focused card first, then by on-screen area (a busy holder keeps its context against a card less than 1.25× larger), then by most recent output. Camera and layout changes settle for 200 ms before contexts move; a card that leaves the screen, zooms above 1× or enters summary mode releases its context (and explicitly loses it) at once. Every other card uses the DOM renderer. A lost context puts the card back on DOM with its buffer intact and keeps it there for 30 s, doubling on repeats; returning to DOM refits the grid, because WebGL cells are snapped down to whole device pixels. - `src/main/services/LimitsService.ts` reads Codex through the installed CLI's app-server protocol and Claude, Kimi, OpenCode Go, and Grok Build through their provider usage or billing endpoints. Qwen Code is multi-provider and exposes no provider-neutral read-only quota protocol, so its adapter reports `cli-not-found` or `unsupported-protocol` and never invents percentages. Provider credentials are read only inside the trusted main process, sent only to the matching provider over HTTPS, and never logged or exposed over IPC. The service owns timeout, structural normalization, caching, stale fallback, and subprocess cleanup; raw provider responses never cross IPC. - `src/main/services/SettingsStore.ts` normalizes every update and persists through a serialized atomic write. Canvas regions and sticky notes have independent persistence gates: disabling one keeps its live objects for the current process but omits that collection from the disk snapshot and therefore from the next launch. The configurable canvas launcher and UI scale use the same boundary; transient window stacking does not. - `src/main/services/PluginManager.ts` installs ready-to-run repositories without executing package scripts during install/update, rejects symlinks and oversized packages, persists the enabled registry, serves only contained package files, and enforces per-plugin permissions/storage quotas. Optional native agent-hook entries remain off by default; explicit per-hook trust is persisted in the plugin registry and compiled into a separate private atomic runtime registry. Update, module replacement, plugin disable, and uninstall revoke that trust before executable files change. - `src/main/services/PluginServiceSupervisor.ts` runs the `services` of an apiVersion 2 plugin only after the separate per-plugin "native code" confirmation, which pins each entry's SHA-256 and is revoked like hook trust. Each service is a `process.execPath` + `ELECTRON_RUN_AS_NODE` child in the plugin folder with an allow-listed environment (no provider keys, tokens, `NODE_OPTIONS`, or `CANVASTTY_*`), newline-delimited JSON-RPC 2.0 over stdio with 1 MB messages and 15 s request timeouts, restart with backoff (at most 5 in 10 minutes), and a bounded per-plugin log. Its host API is `log`, own-plugin `storage.*` behind the `storage` permission, and `event` to the plugin's own surfaces; surfaces reach only their own plugin's services (`service.request`). - `src/main/services/LaunchPipeline.ts` runs before a card with plugin launch options is spawned (create, restart, restore). It sends `canvastty.launch.prepare` to each chosen plugin's trusted launch service (5 s budget), validates the answers, merges them in plugin-id order, resolves `secretEnv` from the plugin's own secrets in main (the values are masked by `TerminalManager.redactSecrets` in agent-readable text), writes per-run files, and refuses the launch on any refusal, timeout, error, conflict, reserved name or core-owned argument (`coreOwnedLaunchArgument`). `TerminalManager` keeps such a card waiting until the answer arrives and never launches it without the contribution; restore holds it stopped when the plugin is unavailable. - `src/main/services/EnvironmentRegistry.ts` talks to trusted services that declare `environments` (`environment:provide`). `TerminalManager` calls `canvastty.environment.prepare` once for a card started in an environment and saves the opaque ref (≤4 KB) in the session record; before every start it calls `wrap` and validates the answer (an absolute executable or a bare name resolved on PATH, never a shell string; launch-contributor env rules; `secretEnv` resolved in main and masked) and still spawns the PTY itself. Restore resumes all saved environments first (`resume`), then plans parents before children; an unavailable plugin, a `stopped` answer or a timeout holds the card stopped with the reason and never runs it locally. Closing a card releases its environment with the person's "Keep environment data?" answer; quitting releases nothing unless saving is off (`keepData: true`). -- `src/main/services/DecisionHooks.ts` answers the decision hook (`src/agent-runtime/permission-gate.mjs` as Claude Code/Codex/Qwen Code `PreToolUse`, `opencode-decisions.mjs` in OpenCode's `tool.execute.before`), which reaches `RuntimeGateway` over the session's runtime capability.

One timer serves every session: the sessions with queued output flush together, and `TerminalRendererOutbox` sends the renderer's share of that flush as one `terminal:data-batch` message (session and removal events first flush what was collected before them, so order is kept). The preload hands each event only to the card of that session (`TerminalDataRouter`), not to every card. Scrollback trimming advances through chunks instead of rebuilding the entire buffer for every write; snapshots join only the retained suffix. Terminal cards subscribe before requesting a fresh `terminal:read-buffer` snapshot. The snapshot and live batches carry the cumulative UTF-16 output offset, which survives history trimming and in-place restarts. The renderer removes their overlap before writing to xterm, so delayed batches cannot duplicate replayed history and output before subscription is recovered by the snapshot. diff --git a/docs/ARCHITECTURE.zh-CN.md b/docs/ARCHITECTURE.zh-CN.md index 70d8af7e..06951eac 100644 --- a/docs/ARCHITECTURE.zh-CN.md +++ b/docs/ARCHITECTURE.zh-CN.md @@ -30,6 +30,7 @@ Electron main process - `src/preload/index.ts` 只暴露 renderer 需要的类型化能力。Node integration 保持关闭，context isolation 与 sandbox 保持开启。 - `src/main/ipc/registerIpc.ts` 负责原生 side effect，并校验对持久化媒体的访问。 - `src/main/services/TerminalManager.ts` 是实时会话状态与 PTY buffer 的事实来源。它保存有界 scrollback，并将 PTY data 合并为 16ms IPC batch。普通终端从 `idle` 开始；智能体在收到首个机器可读 provider lifecycle signal 前保持 `unavailable`。之后 Codex、Claude Code、Qwen Code、Kimi Code、OpenCode、Hermes 与 Grok Build 通过 provider hook 在 `idle`、`working` 和 `needs_approval` 之间切换；Claude/Qwen 的精确 OSC 0/2 marker 保留为兼容 fallback。不会根据 PTY 是否存在或人类可读终端文字推断活动。进程退出只产生 `done` 或 `failed`。 +- `src/renderer/src/features/terminal/webglContextPool.ts` 决定哪些终端卡片使用 xterm 的 WebGL renderer。Chromium 每个 renderer 进程最多保留 16 个 WebGL context，因此池只分配 10 个：先给聚焦的卡片，再按屏幕可见面积（持有 context 且仍活跃的卡片，面对面积不足其 1.25 倍的卡片时保留 context），最后按最近输出。镜头与布局变化需静止 200 ms 后才会移动 context；离开屏幕、缩放超过 1× 或进入摘要模式的卡片立即释放（并显式丢弃）context。其余卡片使用 DOM renderer。context 丢失时卡片回到 DOM，buffer 不变，并在 30 s 内（重复丢失时翻倍）不再使用 WebGL；回到 DOM 时重新 fit 网格，因为 WebGL 的 cell 宽度向下取整到整数设备像素。 - `src/main/services/LimitsService.ts` 通过已安装 CLI 的 app-server protocol 读取 Codex，并通过服务商 usage/billing endpoint 读取 Claude、Kimi、OpenCode Go 与 Grok Build。Qwen Code 是多服务商 CLI，没有 provider-neutral quota-read protocol，因此其 adapter 明确返回 `cli-not-found` 或 `unsupported-protocol`，不会伪造百分比。凭据只在可信主进程读取，只通过 HTTPS 发往匹配的服务商，不记录也不通过 IPC 暴露。该服务负责 timeout、structural normalization、cache、stale fallback 与子进程 cleanup；原始服务商响应不会跨越 IPC。 - `src/main/services/SettingsStore.ts` 会规范化每次更新，并通过串行原子写入持久化。 - `src/main/services/PluginManager.ts` 安装已构建的静态仓库，不执行 package script；拒绝 symlink 与超大包；持久化启用 registry；只提供包内文件，并执行每插件 permissions/storage quota。 @@ -81,7 +82,7 @@ App 一个实时 `TerminalCard` 在对应 session ID 的整个生命周期内拥有同一个 xterm instance。切换 palette 时就地更新 `terminal.options.theme`；title/settings 变化不得销毁 terminal 或 renderer scrollback。窗口标题通过 `terminal:rename` 作为 session metadata 更新。与进程退出竞态的 PTY input/resize event 在主进程边界内处理，不会形成未捕获 Electron error。 -输出 batching 是 IPC/rendering 边界，而不是历史边界：每个 PTY chunk 都立即追加到有界 scrollback；待发送的 renderer 输出在 16ms timer、exit 前和 dispose 前 flush。Scrollback trimming 通过推进 chunk 完成，不会每次写入都重建整个 buffer；snapshot 只 join 保留的后缀。 +输出 batching 是 IPC/rendering 边界，而不是历史边界：每个 PTY chunk 都立即追加到有界 scrollback；待发送的 renderer 输出在 16ms timer、exit 前和 dispose 前 flush。所有会话共用一个 timer：同一次 flush 的 renderer 输出由 `TerminalRendererOutbox` 作为一条 `terminal:data-batch` 消息发送（session/removed 事件会先 flush 之前收集的输出，保持顺序）；preload 只把事件交给对应会话的卡片（`TerminalDataRouter`）。Scrollback trimming 通过推进 chunk 完成，不会每次写入都重建整个 buffer；snapshot 只 join 保留的后缀。 终端指针坐标在 selection/wheel handling 前，从画布视觉变换后的矩形转换回 xterm layout 坐标。终端与画布滚轮方向从持久化设置中独立规范化。选中文字通过类型化 clipboard bridge 使用 `Ctrl+C`、`Ctrl+Shift+C` 或 `Cmd+C` 复制；使用 `Ctrl+Shift+V`、`Cmd+V` 或 `Shift+Insert` 粘贴，并通过 `Terminal.paste` 而非 synthetic keystroke 进入 xterm。`Shift+Enter` 直接向 PTY 发送 CSI-u modified Enter。 diff --git a/docs/performance-benchmark.md b/docs/performance-benchmark.md new file mode 100644 index 00000000..b4ab5e77 --- /dev/null +++ b/docs/performance-benchmark.md @@ -0,0 +1,50 @@ +# Runtime benchmark + +`scripts/bench-runtime.mjs` measures what CanvasTTY costs while it runs: memory and CPU of the built app, +and the main-process hot paths that grow with the number of cards.
