perf(ci): cut cloud parity time — public static site + sharded BrowserStack (CDP) by RaananW · Pull Request #302 · BabylonJS/Babylon-Lite

RaananW · 2026-06-25T09:55:50Z

Why

The CI wall-clock is dominated by the Parity (Cloud) job, which runs all ~198 parity scenes serially on a single BrowserStack session behind an always-on Local tunnel. Real Azure DevOps run data (pipeline def #44, last 40 runs) shows it is bimodal for the same scene set: 23 runs averaged 47 min, 17 runs averaged 114 min (max 123.5; some canceled near the 2 h timeout). One slow session taxes all 198 serial scenes, and there's no parallelism to absorb it.

This PR addresses both root causes — the tunnel and the serial single session — matching how Babylon.js main uses BrowserStack (direct CDP, parallelized), while keeping the perf job and local dev unchanged.

What changed

Phase 2 — drop the Local tunnel (`59132d0c`)

Parity pages are served from a public, build-isolated static site (pnpm build:lab-site → upload), and the remote browser loads them directly via PARITY_BASE_URL. No tunnel.
All 233 scene navigations converted to baseURL-relative ("sceneN.html"), with use.baseURL added to both Playwright configs so the same specs work locally and against a path-prefixed public host.
Fixed a latent double-prefix bug in build-lab-site.ts (when the deploy base path itself starts with a reserved prefix like lite, Vite-emitted asset URLs were prefixed twice — also affected the existing Bundle Size deploy).

Phase 1 — shard across parallel sessions via CDP (`780ac474`)

Parity now connects with Playwright's connectOptions.wsEndpoint (wss://cdp.browserstack.com/playwright) — no browserstack-node-sdk, no browserstack.yml. Each Playwright worker is its own cloud session, so the ~198 specs shard across N parallel browsers.
scripts/browserstack-wait.sh grabs up to BSTACK_SESSIONS_REQUIRED (5) sessions from the plan, falls back to fewer when busy, exports CIWORKERS, and retries on queue-size-exceeded.
scripts/redact-secrets.ts + a pipeline step strip BrowserStack creds from test-results before the report/JUnit are published (the CDP wsEndpoint embeds the access key); trace is forced off.
browserstack.yml / run-browserstack.ts reverted to master — they are now used only by the perf job, which keeps the SDK + tunnel.

Expected impact

Parity slow bucket ~114 min → ~23 min at 5 sessions, with the variance largely collapsed (no single-session tax, no tunnel).
Perf, bundle-size, unit, and local dev workflows are unchanged.

Verification

Functional headless load of a built scene1.html under the prefixed base path → 0 failed requests (fully self-contained; the only error was local "WebGPU adapter not available", which BrowserStack provides).
CDP config resolves correctly (workers from CIWORKERS, fullyParallel, correct caps incl. playwrightVersion, webServer dropped when public URL set); both fallback paths verified.
Redaction script verified to strip key + username from HTML/XML.
Tests typecheck clean; format:check clean; eslint 0 errors; all YAML valid; browserstack-wait.sh passes bash -n.

Notes / follow-ups

This touches tests/configs/pipeline only (no engine src changes), so the parity/bundle suites are not required by the repo guardrails; perf is never run by agents.
Possible later optimization: drop the now-redundant build:bundle-scenes step in the ParityCloud job, and consider moving the perf job off the SDK/tunnel too.

…ck tunnel Phase 2 of the CI BrowserStack overhaul. Parity (Cloud) is the CI wall-clock bottleneck and is bimodal (~47 min vs ~114 min for the same ~198 scenes). The dominant source of variance is the always-on BrowserStack Local tunnel that fronts a single serial session: one slow tunnel taxes every one of the 198 serially-run scenes. This removes the tunnel from the cloud parity path by serving a self-contained static parity site from a public, build-isolated URL and pointing the remote browser straight at it. - tests/lite/parity: navigate with baseURL-relative paths ("sceneN.html") instead of absolute ("/sceneN.html") so the same specs resolve under a path-prefixed public host or localhost. - playwright.config.ts + parity-cloud config: add use.baseURL. When PARITY_BASE_URL is set, parity-cloud uses it as baseURL and drops the local webServer; otherwise it keeps the local dev-server fallback. - browserstack.yml: browserstackLocal is now ${BROWSERSTACK_LOCAL}; run-browserstack.ts disables the tunnel when PARITY_BASE_URL is set (assets already come from public CDNs), else defaults it on. - azure-pipelines.yml ParityCloud: build + upload a build-isolated static parity site and run parity against its public URL (no tunnel). Upload template gains an optional postComment flag (no PR comment for parity). - build-lab-site.ts: fix latent double-prefix bug — when the deploy base path itself starts with a reserved prefix (e.g. /lite/<build>/...), Vite-emitted asset URLs were prefixed a second time. The rewrite now skips URLs already under the base path. - TESTING.md: document the dual-mode (public site vs local tunnel) parity serving. Local fallback is preserved, so this is non-breaking.

…a CDP Phase 1 of the CI BrowserStack overhaul. The cloud parity job ran all ~198 scenes serially on a single BrowserStack session (the SDK with parallelsPerPlatform: 1), which is the CI wall-clock bottleneck and the source of its 47-min↔114-min bimodal variance. Migrate parity to a direct CDP connection and shard it across parallel cloud sessions: - playwright.parity-cloud.config.ts: connect via Playwright's connectOptions.wsEndpoint (wss://cdp.browserstack.com/playwright) with capabilities built in-config — no browserstack-node-sdk, no browserstack.yml, no Local tunnel. fullyParallel + workers=CIWORKERS so each worker is its own cloud session. Keeps the public-site baseURL and a local-Chrome fallback. trace is forced off (the wsEndpoint embeds the access key). - scripts/browserstack-wait.sh: poll the BrowserStack plan API, grab up to BSTACK_SESSIONS_REQUIRED sessions (fall back to fewer when busy), export CIWORKERS, and retry on queue-size-exceeded. - scripts/redact-secrets.ts + pipeline step: strip BrowserStack creds from test-results before the report/JUnit are published, in case a connection error echoes the wsEndpoint. - azure-pipelines.yml ParityCloud: run via the wait script with BSTACK_SESSIONS_REQUIRED=5; redact artifacts before publishing. - package.json: test:parity-cloud now runs Playwright directly. - browserstack.yml / run-browserstack.ts: reverted to master — they are now used only by the perf job, which still uses the SDK + tunnel. - TESTING.md: document the parity (CDP/sharded) vs perf (SDK/tunnel) split. Perf and local dev are unchanged, so this is non-breaking. Expected effect: parity slow bucket ~114 min -> ~23 min at 5 sessions, with the variance largely collapsed.

Pull request overview

This PR aims to cut CI wall-clock time for Parity (Cloud) by removing the BrowserStack Local tunnel dependency and parallelizing parity execution across multiple BrowserStack sessions via direct Playwright CDP. It also makes parity/bundle-size navigation baseURL-relative so the same specs can run against a path-prefixed, build-isolated public static site in CI (and still work locally).

Changes:

Switch Parity (Cloud) to Playwright connectOptions.wsEndpoint (no BrowserStack SDK / browserstack.yml) and shard across parallel sessions controlled via CIWORKERS.
Build + upload a public static parity site (pnpm build:lab-site) and run cloud parity against it via PARITY_BASE_URL (no Local tunnel).
Update parity and bundle-size tests to use baseURL-relative page.goto(...), add local baseURL to playwright.config.ts, and add CI artifact credential redaction.

The parity static-site build ran rewriteRootRelativeUrls() over Vite's minified Babylon.js chunks, matching after (, =, : and whitespace. That mangled regex literals such as .replace(/gl_FragColor/g, ...) into .replace(/lite/<build>/parity-lab/gl_FragColor/g, ...) (invalid regex flags -> chunk crash) and glTF JSON pointers like m.Get(\\\/scene\\\). Reference pages then failed to load, so every live-captured golden scene timed out in cloud parity. For .js/.json the rewriter now only matches inside quoted string literals and only rewrites tokens that look like real asset URLs (file extension or sub-path), leaving regex literals and JSON pointers untouched while still basing genuine runtime URLs (scene-config.json, reference/, textures/, HavokPhysics.wasm, etc.). CSS/HTML keep the original broad behaviour. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

…emplate Every CI job re-ran corepack + 'pnpm install --frozen-lockfile' from scratch, and two jobs re-downloaded Playwright browsers. Extract the bootstrap into a reusable config/templates/install-deps.yml step template that adds a cross-run pnpm store cache (keyed on pnpm-lock.yaml) and an optional Playwright browser cache, then reference it from all eight jobs. Dependency installs now hit the cache on the common unchanged-lockfile path, and the duplicated corepack/install blocks collapse to a single template. Note: build:bundle-scenes (3 jobs) and build:lab-site (2 jobs) are intentionally not cached — their output changes on every commit, so a cache would never hit.

The .gitignore was silently ignoring every reference/lite/**/babylon-ref-golden.png (only 59 of 204 scenes were committed via git add -f). Scenes without a committed golden fall into captureGolden()'s live-capture path, booting a full Babylon.js reference page on every CI run (~10x slower per scene, network-flaky) — which contradicts GUIDANCE §2c ('no parity test may open a BJS reference page at runtime'). - .gitignore: keep transient babylon-ref-*.png ignored but explicitly allow babylon-ref-golden.png, so new goldens commit without git add -f. - TESTING.md: rewrite the Golden References section (performance rationale, macOS-capture requirement, recapture commands) and add an 'Adding a new scene' checklist; fix stale spec count and page name. - GUIDANCE.md: make the new-scene golden step explicit (capture on macOS, commit in the same PR, goldens are tracked). Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

Add an opt-in strict mode to captureGolden that throws when a scene's committed golden is missing, instead of silently live-capturing the Babylon.js reference page at runtime (slow, ~10x per scene, forbidden by GUIDANCE 2c). Wire PARITY_REQUIRE_GOLDEN=false into the cloud parity job with a flip-to-enable comment, and document the env var in TESTING.md. Default OFF so the current run still passes while the 144 missing goldens are captured on macOS and committed; flip to true afterwards.

…l goldens The golden capture swept up 69 goldens into a legacy top-level reference/<slug>/ tree that no test references (lite specs read reference/lite/<slug>, gl specs read reference/gl/<slug>). They leaked in because the .gitignore golden negation un-ignores goldens in every tree, so git add grabbed old previously-ignored captures off disk. - Move scene40-physics golden from reference/scene40-physics/ to reference/lite/scene40-physics/ (it had landed only at the top level, leaving the lite spec without a golden). - Delete the remaining 68 orphaned top-level goldens. Result: 204/204 lite parity specs have a committed golden, no orphans. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

Blanket RECAPTURE_GOLDEN regenerated all 203 goldens, rewriting 53 that were already committed and valid. The changes are pure render noise (51 of 53 below MAD 0.5, 39 below 0.1; the two largest ~1.0, all within each scene's maxMad threshold) -- no visual change, just churn on large binary PNGs. Restore those 53 to their original committed bytes; keep only the 144 genuinely-new goldens. Going forward the harness only overwrites an existing golden when RECAPTURE_GOLDEN is set, so normal runs won't churn. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

13 cloud parity tests failed because asset/page URLs bypassed the new per-build base path on the public static site and 404'd at the domain root: - scene254/255/257/258/259/260: page.goto used a leading-slash path (/sceneN.html) that resolves to the domain root, ignoring the base path. Made the goto paths relative so they resolve against PARITY_BASE_URL. - scene170-175 (recast) and scene211 (meshopt): the lab-site URL rewriter allowlist (ROOT_RELATIVE_PREFIXES) rebases HavokPhysics.wasm and draco but not recast-navigation.wasm or meshopt_decoder.js, so their wasm/JS 404'd and init hung until the 120s timeout. Added both to the allowlist. - scene211 also composes the meshopt decoder URL at runtime (default base '/'), so the allowlist alone can't catch it; set the meshopt base relative to the page URL so it works under any base path.

Parity scenes referenced root-absolute asset URLs (NME texture maps baked into compressed snippet data, and the Draco/meshopt decoder scripts) that resolve against the site root. Under the per-build base path used by the cloud parity static site they 404, so scene72 fell back to a plain sphere, scene66/140 threw on the missing textures and never became ready, and scene30 hung waiting on /draco_decoder.js. Add lab/lite/src/shared/asset-url.ts which rebases such URLs at runtime against document.baseURI (the proven scene211 precedent) instead of the build-time rewriter, which cannot see URLs hidden in compressed blobs or constructed at runtime. Wire it into the NME texture loads (scene72/66/140) and the Draco/meshopt decoder bases (scene30). Regenerate the affected per-scene bundle manifests (scene211 also picks up its earlier meshopt edit). Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

… lean The parity static-site work wired configureParityDecoderBases() into scene30 (and an inline equivalent into scene211) that eagerly import()-ed the Draco and meshopt decoder wrappers solely to call their base-URL setters. That static import pulled both decoders into the scene bundle — defeating their zero-byte lazy-load design and pushing scene30 (+draco+meshopt) and scene211 (+meshopt) over their committed size ceilings. scene30 doesn't even use meshopt. Make draco-decode.ts and meshopt-decode.ts resolve their base URL lazily from a new __babylonLiteDecoderBase__ global (explicit setDraco/MeshoptBaseUrl() still take precedence; default stays "/"). configureParityDecoderBases() now just sets that global synchronously — no import — so the decoders are only pulled in when a scene actually loads a compressed asset (the glTF feature dynamic-imports them on demand and they pick up the base). scene30 104.3 -> 103.4 KB (ceiling 103.5), scene211 90.5 -> 90.3 KB (ceiling 90.4): both back under ceiling with no ceiling change. Backward compatible — demos using the explicit setters are unaffected. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

… under tree-shaking The glTF primitive feature and KHR_animation_pointer feature installed the PBR primitive-state resolver and the non-Float32 sampler converter via bare side-effect imports (`import "...";`). Under the engine's `"sideEffects": false`, Rollup drops those imports from the per-scene production bundles, so: - non-triangle topologies / negative-winding meshes silently fell back to plain triangle-list (scene257 negative-node-scale, scene260 triangle-strip rendered wrong: parity MAD 2.33 / 26.37 vs 0.1 limit), and - normalized / non-Float32 animation samplers reverted to the Float32 fast-path reinterpret. Wrap each install in an idempotent exported initializer and call it through a used binding from the feature module, so the reference survives tree-shaking regardless of the `sideEffects` hint. Triangle-list scenes still never load these modules, so their bundles stay byte-identical. Co-authored-by: Copilot App <223556219+Copilot@users.noreply.github.com>
