chromium-bin: source from Chrome for Testing Stable 155.0.8059.84 (both arches) — licensing review needed - #928
bryan-minimal wants to merge 2 commits into
Conversation
…th arches) Playwright stopped publishing linux-arm64 Chromium after r1243, so the arm64 leg was a dead source and pkgmgr refused every newer target. CfT now publishes the full `chrome` bundle for linux-arm64 as well as linux64; move both legs to CfT Stable, matching chromium-headless-shell-bin (one zip per arch, `snapshot_position` gone, `revision` kept only as the Playwright registry directory key). Licensing: the CfT `chrome` bundle ships the proprietary Widevine CDM (build.sh now deletes it and fails if any Widevine file survives) and carries no BSD grant (ABOUT: "All rights reserved", Chrome ToS), so license_spdx names the Google terms and the package must be excluded from the public binary cache before this merges. Tests: exact-version smoketest, --headless=new --dump-dom launch, and a Playwright-layout + no-Widevine check. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

It is not the origin of the bytes (binary_from is), but supply-chain's cpe_remap keys google:chrome on pkg:github/microsoft/playwright; dropping it would make the package scan 0/0/0. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

Holding this pending a licensing decision. The mechanics check out: both sha256s and sizes match, the arch handling is right (per-arch Source/binary_from, the chrome-linux symlink on arm64, layout_check), and the LicenseRef-Google-Chrome-for-Testing-ToS label is honest.
Before this can merge
- It reverses the inbox#284 decision for amd64. Today amd64 ships genuine BSD Chromium from the snapshot bucket; only arm64 lacks a redistributable source. Alternatives:
- keep amd64 on snapshots and use CfT for arm64 only;
- Debian
chromium(open source, ~47 more runtime libs); - this PR's local-download-only approach.
- Codecs. Besides Widevine, the
chromebinary has ffmpeg's H.264 and AAC decoders compiled in. Those are patent-licensed codecs that open-source Chromium builds leave out, and the PR doesn't mention them. That's one more reason it must never be cache-served. - The safeguard lives outside this repo.
chromium-binmust be inNON_REDISTRIBUTABLE_NAMES(build-serverscrates/buildbot/src/commit_index.rs) and deployed before merge. Otherwise the first official build uploads Google's binary to the public cache. Please link the deploy here. - amd64 doesn't appear to have been built.
minimal buildtook 15s, yet the PR says amd64 is "left to this PR's CI". Please get a real amd64 build and test run.
Smaller
- Two comments go stale and aren't updated:
packages/chromium-headless-shell-bin/build.ncl:58-59("stays on true open-source Chromium") andpackages/agent-browser/build.ncl:17-26(describes the old sources). - Keep the version in lockstep with chromium-headless-shell-bin and
chromedriver-bin(#848).

Closing in favour of #960, which moves chromium-bin to ungoogled-chromium-portablelinux 155.0.8059.84 on both arches instead (interim source, decided 2026-10-20). That build is BSD-3 and redistributable, carries no Widevine and needs no NON_REDISTRIBUTABLE_NAMES entry, so the licensing gate this PR was blocked on goes away. The reusable parts (Playwright registry layout incl. the arm64 chrome-linux-arm64 dir + compat symlink, exact-version smoketest, layout/Widevine check, fail-closed required-file checks) carried over. |
Closes the
chromium-binhalf of #684 (the headless-shell half was #718 / #894).Why
chromium-binships Chrome 153.0.8010.12, and it can't be updated. The arm64 leg comes from Playwright's CDN, and Playwright stopped publishing linux-arm64 Chromium after r1243: the newest revision, r1249 (156.0.8078.12), returns 400 forchromium-linux-arm64.zip. So pkgmgr's resolver correctly refuses every newer target, and the nightly auto-fix fails.Chrome for Testing now publishes the full
chromebundle, andchromedriver, for linux-arm64 as well as linux64 (supported since 153.0.8001.0). Both legs therefore move to CfT Stable 155.0.8059.84, which is current Stable perlast-known-good-versions-with-downloads.jsonon 2026-10-18 and the same version aschromium-headless-shell-bin.snapshot_position1681086linux64/chrome-linux64.ziplinux-arm64/chrome-linux-arm64.ziprevision+browser_version+snapshot_positionbrowser_versiononly (revision= registry dir key)Stable, not Beta (157.0.8103.6): Beta matches ~0 CVEs today and a few hundred once its major goes stable. The security win comes from the channel. This also retires the "pre-stable BY DESIGN" header.
The sha256s were computed from the downloads, since CfT publishes no checksum file:
URLs point straight at
storage.googleapis.com/chrome-for-testing-public/..., the same convention as headless-shell and chromedriver-bin (no gs:// mirror).Licensing: needs your review
I checked both zips at 155.0.8059.84 (

build.shrunsrm -rf WidevineCdm/and then fails the build if any*widevine*file survives. A standalone test (layout_check) also asserts it's absent from the installed tree. Chrome runs without it; only EME/DRM playback is lost.license_spdx = "LicenseRef-Google-Chrome-for-Testing-ToS", notBSD-3-Clause. The Chromium sources are BSD, but what we ship is Google's branded binary, and it comes without that grant. If you read the terms differently once Widevine is gone, this is a one-line flip, but I didn't want to claim a grant the bundle doesn't carry."chromium-bin"toNON_REDISTRIBUTABLE_NAMESincrates/buildbot/src/commit_index.rs. The pkgs attr was withdrawn in Revert #477: restore minimum_version 0.0.15, drop redistributable attr (unblock pinned-minimal consumers) #536, so the denylist is the mechanism. Consumers then "build" locally, which here means a 199 MB fetch from Google plus an unzip. No CLI change is needed, since an index miss already means build locally.If non-redistributable is a dealbreaker, the redistributable alternative is Debian's
chromium(DFSG-free, Widevine-free, both arches, open-source BSD), at the cost of a far larger runtime closure (~47 libs: libpulse, openh264, dav1d, FLAC, opus, minizip, …). Theagent-browserheader already notes this as the path back.Playwright compatibility: kept, with evidence

The resolver is source-shape-driven: it classifies each package from the URLs in its own build.ncl. With all-CfT URLs, chromium-bin automatically resolves like headless-shell (CfT Stable history plus the CfT known-good download list, rewriting
browser_versionand both sha256s). No pkgmgr deploy has to precede or follow this. The companion pkgmgr-rs PR adds fixtures and tests for this exact shape and updates the stale docs and messages.🤖 Generated with Claude Code
