From d60bc1575b52b2cd0af8dea8e678e90621f66f43 Mon Sep 17 00:00:00 2001 From: Istvan Matejcsok <119620946+matejcsok-ee@users.noreply.github.com> Date: Fri, 3 Jul 2026 15:35:17 +0200 Subject: [PATCH] =?UTF-8?q?fix(ci):=203D=20specs=20=E2=80=94=20180s=20view?= =?UTF-8?q?er-open=20wait=20for=20llvmpipe;=20skip=20deadlock=20spec=20on?= =?UTF-8?q?=20CI?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Follow-up to the headed-llvmpipe switch. That run (28652367347) stopped CRASHING — every failure became a plain timeout, confirming llvmpipe gives a stable WebGL context (no more CONTEXT_LOST / "Target crashed") but software raytracing is just slow: - The first board raytrace takes ~60s on llvmpipe, right at openThreeDViewer's 60s wait → raise it to 180s (shared helper + the models spec's inline copy). Real GPU returns in ~2s, so it is only CI headroom. - The deadlock spec asserts the wasm main thread stays responsive within ~15s DURING a raytrace — a premise only true on a fast (real) GPU. Under slow software rendering a legitimately-slow raytrace is indistinguishable from a deadlock, so skip it on CI (test.skip on process.env.CI). The Worker-boot deadlock MECHANISM stays covered on CI by the standalone coroutine-pthread-ondemand / raytrace-threads wx harnesses; the spec still runs locally on a real GPU. - Gate the headed + llvmpipe launch flags on CI so chromium-ci-3d behaves like a normal bundled-Chromium project locally.
