feat(pvm): run App Manifest v2 runtimes in Dotli by replghost · Pull Request #185 · paritytech/dotli-community

replghost · 2026-08-28T08:17:19Z

What

load signed PolkaVM App v2 archives in the sandbox.
run framebuffer, Tri2D, and WebGPU profiles through the host runtime bridge.
consume truapi-pvm-host@e892cd9d and standalone runtime v0.1.5@81a484a1 through the reviewed bridge.
synchronize and verify browser assets from the bridge exporter with one source-bound lock.
route baseline TrUAPI request/response frames between PVM workers and Dotli’s canonical product MessagePort.
refresh translated/interpreter WebGPU capabilities after resize so stale surface generations recover.
resolve optional motion input as unavailable when a browser host has no active sensor source; pointer input remains the fallback.
keep the runtime namespace outside product-controlled service-worker routes.
add configurable seven-app smoke coverage.

Verification

sandbox tests: 21 passed, including canonical MessagePort negotiation.
sandbox lint and TypeScript checks: passed.
production sandbox build: passed with bridge-owned runtime 0.1.5 assets.
bridge asset synchronization and checksum gate: passed.
focused PVM functional suite: passed.
App Kit pvm-truapi-playground CAR: compiler/Tri2D rendering passed and canonical TrUAPI handshake request/response counters both advanced.
Chinpokomon App v2: compiler/WebGPU rendering, window resize, and subsequent input passed.
canonical seven-app Dotli compiler matrix: passed.

@justraman the PVM change is green across formatting, build, unit, functional, and the canonical seven-app Dotli matrix. The broad host-playground E2E remains red on the same account, allowance, and navigation failures as current main (the latest main Tests runs also fail); it does not exercise this PVM path. Could you review the runtime adapter so this can follow host-rust-core#540?

Live doom.paseo clarification:

The deterministic DOTLI_DOOM_V2_CAR test is a separate fixture test and was skipped locally because no CAR/manifest file paths were supplied.
The focused compiler and forced-interpreter PVM browser tests pass.
I ran tests/performance/pvm-doom.spec.ts against the live Paseo products. Doom, Quake, and Duke all timed out before the product iframe mounted; the host remained at its loading surface, so this did not reach PVM execution.
https://doom.paseo.li currently resolves a published CID, but the deployed host sends sandbox contract v=3 without executableManifest; the sandbox then reports Archive missing index.html. Reloading the available service-worker update still produced the same v3 contract.

Therefore doom.paseo is published/live, but it is not yet a passing live Dotli PVM acceptance result. The PR's deterministic PVM path is green; live acceptance still needs a deployed/current host-sandbox pair or a repaired local live resolver.

Warm-cache reload is now fixed in 1a8aa4d839bdf6f5a74a125eae24578d8f043914.

Root causes:

performance Playwright reused any process already listening on port 5173, so local runs could silently test a stale build;
a same-iframe reload posted a second truapi-ready, but the Host had removed its probe listener after the first handshake and the original MessagePort could not be transferred again;
runtime readiness did not wait for the translated-byte IndexedDB write to settle.

Changes:

isolated performance server via PERF_PORT and reuseExistingServer: false;
retain the modern Host handshake listener and replace the product-side provider with a fresh MessageChannel on every subsequent truapi-ready;
wait for the bounded translation-cache write before exposing runtime readiness;
behavioral unit coverage for the second port handoff.

Verification on an isolated current branch build:

live doom.paseo manifest resolution: passed;
live Quake translated runtime: passed;
live Duke bounded hostcall/audio runtime: passed;
live Doom cold compiler/playability and warm same-iframe cache hit: passed;
full live PVM performance file: 4/4 passed;
UI tests: 217 passed;
sandbox tests: 17 passed.
