* ci: use hermetic mac SDK for the release ffmpeg build
gn gen out/ffmpeg runs as a raw gn invocation, so it never receives the
mac_sdk_path arg that e build injects for out/Default. On macOS runners
that means out/Default builds against the hermetic build-tools SDK while
out/ffmpeg falls through to the runner's system Xcode SDK. Reuse the
value e build already wrote so both builds share the same sysroot.
* ci: copy hermetic SDK symlink into out/ffmpeg and rewrite path
mac_sdk_path must live under root_build_dir, so pointing out/ffmpeg at
//out/Default/... doesn't work. Copy the xcode_links symlink tree into
out/ffmpeg and rewrite the path. Gate on Darwin so Windows/Linux don't
run the sed/cp at all.
ci: make src-cache upload atomic and sweep orphaned temp files
The checkout action's cp of the ~6GB zstd archive directly to the final
path on the cache share is non-atomic; an interrupted copy or a
concurrent reader produces zstd "Read error (39): premature end" on
restore, and the truncated file then satisfies the existence check so
no later run repairs it.
Upload to a run-unique *.tar.upload-<run_id>-<attempt> temp name on the
share and mv to the final path, discarding our temp if a concurrent run
got there first. A new clean-orphaned-cache-uploads workflow removes
temp files older than 4h every 4 hours.
fix-sync re-downloads llvm-build on macOS/Windows with the base clang
and objdump packages, but not clang-tidy. A local gclient sync pulls
clang-tidy (checkout_clang_tidy=True in DEPS), so CI's llvm-build tree
diverges from a local one. siso hashes the toolchain as action input,
so cache-only local runs against the CI-populated RBE cache miss.
* ci: shrink src cache and fix Windows tar cleanup
- Exclude platform-specific toolchains (llvm-build, rust-toolchain) from
the src cache; all platforms now fetch them via fix-sync post-restore
- Exclude unused test data and benchmarks: blink/web_tests, jetstream,
speedometer, catapult/tracing/test_data, swiftshader/tests/regres
- Fix Windows restore leaving the tarball on disk after extraction
($src_cache was scoped to the previous PowerShell step)
- Bump src-cache key v1 -> v2
* ci: fetch llvm/rust toolchains in gn-check and clang-tidy
These workflows restore the src cache but don't run fix-sync. Now that
llvm-build and rust-toolchain are excluded from the cache, they need to
download them directly — gn gen read_file()s both, and clang-tidy runs
the binary from llvm-build.
* ci: fetch clang-tidy package explicitly
update.py's default 'clang' package doesn't include the clang-tidy
binary; it ships as a separate package.
* ci: preserve blink/web_tests/BUILD.gn when stripping test data
//BUILD.gn references //third_party/blink/web_tests:wpt_tests as a
target label, so the BUILD.gn must exist for gn gen. The data = [...]
entries it declares are runtime-only and not existence-checked at gen
time, so the actual test directories can still be removed.
* ci: compress src cache with zstd and drop gclient sync -vv
The src cache was an uncompressed tar (~16GB after exclusions). Switch
to zstd -T0 --long=30 for ~4x smaller transfer and multi-threaded
compression. Decompress on restore:
- Linux/macOS: zstd -d -c | tar -xf -
- Windows: zstd -d to an intermediate .tar, then the existing 7z
-snld20 extraction (preserves symlink handling)
All filename references updated .tar -> .tar.zst. -f added to the two
-o invocations so re-runs overwrite instead of failing.
Also drop -vv from gclient sync; default verbosity is sufficient.
* ci: keep .tar extension for src cache (zstd content inside)
The sas-sidecar that issues Azure SAS tokens validates filenames against
/^v[0-9]+-[a-z\-]+-[a-f0-9]+\.(tar|tgz)$/ and is not easily redeployed,
so keep the .tar extension and decode zstd on restore. Windows
decompresses to a distinct intermediate (src_cache.tar) so input and
output don't collide.
* ci: log NTFS 8.3/lastaccess/Defender state before Windows cache extract
Temporary diagnostics to see whether 8.3 short-name generation is the
cause of the ~20 min tar extraction.
* ci: revert src-cache exclusion additions
The new exclusions (web_tests contents, jetstream, speedometer,
catapult test_data, regres, llvm-build, rust-toolchain) caused siso/RBE
cache misses — even data-only deps are part of action input hashes.
Revert to the original exclusion list and drop the corresponding
toolchain-fetch plumbing. zstd compression, the Windows tar cleanup,
and the -vv removal remain.
* ci: drop win_toolchain from src cache; remove NTFS diagnostics
The Windows src cache includes 14.6GB of depot_tools/win_toolchain —
7.3GB of MSVC/SDK doubled because tar captures both the vs_files.ciopfs
backing store and the live ciopfs mount at vs_files/. Every Windows
cache consumer already re-fetches this via vs_toolchain.py update
--force (fix-sync for build/publish, inline for gn-check/clang-tidy),
so the cached copy is never used.
Diagnostics removed — CI confirmed 8dot3, last-access, and Defender are
all already off on the AKS Windows nodes.
* ci: unmount ciopfs vs_files before removing win_toolchain
vs_files is a live ciopfs mount during the win-targeted checkout; rm -rf
fails with EBUSY until it's unmounted.
* ci: skip win_toolchain download during checkout instead of removing after
fusermount isn't on the checkout container, so the ciopfs mount can't be
torn down before rm. Setting DEPOT_TOOLS_WIN_TOOLCHAIN=0 makes the
win_toolchain hook a no-op (vs_toolchain.py:525-527), so there's no
download and no mount. All Windows consumers re-fetch it post-restore
anyway. The rm -rf stays as a safety net.
* ci: also set ELECTRON_DEPOT_TOOLS_WIN_TOOLCHAIN=0 for checkout sync
build.yml sets ELECTRON_DEPOT_TOOLS_WIN_TOOLCHAIN=1 at the job level for
the Windows checkout, which makes e d inject DEPOT_TOOLS_WIN_TOOLCHAIN=1
and override the inline =0. Need both: the ELECTRON_ var stops e d from
overriding, the plain one stops vs_toolchain.py from defaulting to 1.
* ci: extract Windows src cache with piped tar instead of 7z
7z takes ~20 min to extract the ~1.1M-entry tar regardless of size —
~1ms per entry of header parsing and path handling, single-threaded,
well under the 75k IOPS / 1000 MBps the ephemeral disk can do. Switch
to the same zstd -d | tar -xf - pipe used on Linux/macOS (via Git Bash
tar). No intermediate src_cache.tar, download deleted after extract.
The -snld20 flag was working around 7z's own "dangerous symlink"
refusal; GNU tar extracts symlinks as-is so it shouldn't be needed.
* ci: keep depot_tools/win_toolchain scripts in src cache
The rm -rf removed get_toolchain_if_necessary.py (a depot_tools source
file), breaking vs_toolchain.py update --force on restore.
DEPOT_TOOLS_WIN_TOOLCHAIN=0 on the sync already prevents the vs_files
download, so the rm was only removing scripts.
* ci: split src cache into 4 parallel-extractable shards
Windows tar extraction is ~1ms/entry for ~1.2M entries (~20 min)
regardless of tool, well under the 75k IOPS / 1000 MBps the D16lds_v5
ephemeral disk can do. Tar is a sequential stream so the only way to
parallelize is to split at creation time.
Shards (balanced by entry count, ~220-360k each):
a: src/third_party/blink
b: src/third_party/{dawn,electron_node,tflite,devtools-frontend}
c: src/third_party (rest)
d: src (excluding third_party)
DEPSHASH is now the raw hash; shard files are
v2-src-cache-shard-{a..d}-${DEPSHASH}.tar (all pass the sas-sidecar
filename regex). sas-token is now a JSON keyed by shard letter. All
restore paths extract the four shards in parallel with per-PID wait so
a failed shard aborts the step.
* Revert "ci: split src cache into 4 parallel-extractable shards"
This reverts commit 970574998b.
* fix: harden GitHub Actions against script injection vulnerabilities

environment variables to prevent script injection attacks. Changes:
- archaeologist-dig.yml: move clone_url, head.sha, base.ref to env vars
- non-maintainer-dependency-change.yml: move user.login to env var
- issue-unlabeled.yml: move toJSON(labels) to env var
- issue-labeled.yml: move issue.number to env var
- pipeline-electron-lint.yml: validate chromium_revision format
- cipd-install/action.yml: move all inputs to env vars and quote them
- set-chromium-cookie/action.yml: reference secrets via $ENV_VAR
- Add security comments to all 5 pull_request_target workflows

* fix: allow version strings in chromium_revision validation
The previous regex `^[a-f0-9]+$` only matched git SHAs but
chromium_revision is a version string like `148.0.7741.0`.
Broaden to `^[a-zA-Z0-9._-]+$` which still blocks shell
metacharacters.

* build: enable V8 builtins PGO
Removes the gn arg that disabled V8 builtins profile-guided optimization
and adds a V8 patch to warn instead of abort when the builtin PGO profile
data does not match. Also strips the PGO-related flags from the generated
mksnapshot_args so they are not passed through to downstream mksnapshot
invocations.

* ci: add pipeline segment to run clang-tidy
* chore: set -header-filter='' for clang-tidy
Breaking change in `clang-tidy` 22.0.0:
> clang-tidy now displays warnings from all non-system headers by default.
> Previously, users had to explicitly opt-in to header warnings using
> -header-filter=’.*’. To disable warnings from non-system, set
> -header-filter to an empty string.
fix: gate brew commands in free-space-macos action
The brew uninstall and autoremove commands now only run if
