1. Chromium can fire unrelated permission checks (e.g. 'background-sync')
on the default session. Copy a safeguard `permission === 'fileSystem'` from
"calls twice when trying to query a read/write file handle permissions".
2. add afterEach cleanup: reset setPermissionCheckHandler(null) and
remove ipcMain listeners for 'did-create-file-handle' and
'did-create-directory-handle'.

fix: pass root_gen_dir from GN to generate_node_headers.py
PR #50828 replaced a local get_out_dir() (defaulting to 'Testing') with
the shared one from script/lib/util.py (defaulting to 'Default').
Neither default is correct because the actual output directory depends
on the active build config. Pass $root_gen_dir from the GN action so
the script always uses the correct path.

fix: return numeric `blksize` and `blocks` from asar `fs.stat`
Previously, `fs.stat` on files inside `.asar` archives returned
`undefined` for `blksize` and `blocks`, violating the Node.js API
contract where these fields must be `number | bigint`.
Use `4096` for `blksize` (matching the convention used by `memfs` and
the proposed `node:vfs` module in nodejs/node#61478) and compute
`blocks` as `ceil(size / 512)` (standard 512-byte block units).

#47171 migrated `std::deque` to `base::circular_deque` in
`shell/common/crash_keys.cc`. However, `CrashKeyString` wraps a
`crashpad::Annotation` that holds self-referential pointers and
registers itself in a process-global linked list. `circular_deque`
relocates elements on growth (via `VectorBuffer::MoveConstructRange`),
leaving those pointers dangling — causing missing crash keys or a hung
crashpad handler (especially on macOS). The `base/containers/README.md`
warns: "Since `base::deque` does not have stable iterators and it will
move the objects it contains, it may not be appropriate for all uses."
Reverts to `std::deque`, whose block-based layout never relocates
existing elements. Adds a regression test that registers 50 dynamic
crash keys and verifies they all survive a renderer crash.
Notes: Fixed crash keys being lost and the crash reporter hanging on
macOS when many dynamic crash keys were registered.

fix: webContents.print() ignoring mediaSize when silent
PR #49523 moved the default media size fallback into OnGetDeviceNameToUse,
but the new code unconditionally writes kSettingMediaSize — clobbering
any mediaSize the caller had already set in WebContents::Print() from
options.mediaSize / pageSize. As a result, silent prints with an
explicit pageSize (e.g. "Letter") fell back to A4 with tiny content.
Only populate the default/printer media size when the caller hasn't
already supplied one, preserving the precedence:
1. user-supplied mediaSize / pageSize
2. printer default (when usePrinterDefaultPageSize is true)
3. A4 fallback

Menu was holding a SelfKeepAlive to itself from construction, so any
Menu that was never opened (e.g. an application menu replaced before
being shown) stayed pinned in cppgc forever. Repeated calls to
Menu.setApplicationMenu leaked every prior Menu along with its model
and items.
Restore the original Pin/Unpin lifecycle: start keep_alive_ empty and
only assign `this` in OnMenuWillShow. OnMenuWillClose already clears
it.

PR #50646 added a dock state allowlist in SetDockState() that collapsed any
non-matching value to "right". WebContents::OpenDevTools passes an empty
string when no `mode` option is given, which is the sentinel LoadCompleted()
uses to restore `currentDockState` from prefs. The allowlist clobbered that
sentinel to "right", so previously-undocked devtools would flash detached
and then snap back to the right dock.
Preserve the empty string through SetDockState() so the pref-restore path
runs; still reject any non-empty invalid value to keep the JS-injection
guard from #50646 intact.

* 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: 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.

build: derive patches upstream-head ref from script path (#50727)
* build: derive patches upstream-head ref from script path
gclient-new-workdir.py symlinks each repo's .git/refs back to the source
checkout, so the fixed refs/patches/upstream-head was shared across all
worktrees. Parallel `e sync` runs in different worktrees clobbered each
other's upstream-head, breaking `e patches` and check-patch-diff.
Suffix the ref with an md5 of the script directory so each worktree writes
a distinct ref into the shared refs dir. Fall back to the legacy ref name
in guess_base_commit so existing checkouts keep working until next sync.
* fixup: also write legacy upstream-head ref and note it in docs
fix: re-enable MacWebContentsOcclusion with embedder window fix (#50579)
* fix: re-enable MacWebContentsOcclusion with embedder window fix
Replace the full revert of Chromium's MacWebContentsOcclusion cleanup
with a targeted patch that handles embedder windows shown after
WebContentsViewCocoa attachment. This lets us drop the feature flag
disable in feature_list.cc and re-enable upstream occlusion tracking.
Adds tests for show/hide event counts on macOS and visibility tracking
across multiple child WebContentsViews.
* test: drop show/hide event count assertion
The assertion that 'show' fires exactly once per w.show() call is not
an API guarantee - macOS can send multiple occlusion state
notifications during a single show() when other windows are on screen
(common on CI after hundreds of prior tests). The
visibilitychange-count test in api-web-contents-view-spec.ts covers
the actual invariant we care about.
* fix: ignore WebContentsOcclusionCheckerMac synthetic notifications in window delegate
On macOS 13.3-25.x, Chromium's occlusion checker enables manual
frame-intersection detection and posts synthetic
NSWindowDidChangeOcclusionStateNotification tagged with its class name
in userInfo. These fire when the checker's NSContainsRect heuristic
decides a window is covered by another window's frame, but the real
-[NSWindow occlusionState] hasn't changed.
Our delegate was treating these the same as real macOS notifications
and emitting show/hide events based on occlusionState, which was
unchanged - resulting in spurious duplicate show events when e.g.
Quick Look opened and its frame intersected the BrowserWindow.

SENTRYCLI_SKIP_DOWNLOAD=1 in the two test-segment workflows that
call install-dependencies. The 64k variant uses pre-built artifacts

ci: zstd-compress the src cache and drop the doubled win_toolchain (#50702)
* 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-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.

V8's second-pass weak callbacks run inside a
DisallowJavascriptExecutionScope: they may touch the V8 API but must
not invoke JS, directly or indirectly. Several Electron Wrappables
(WebContents in particular) emit JS events from their destructors,
so deleting synchronously inside SecondWeakCallback can crash with
"Invoke in DisallowJavascriptExecutionScope" when GC happens to
collect the JS wrapper during a foreground GC task — typically during
shutdown's uv_run drain after a leaked WebContentsView.
This was previously latent and timing-dependent (electron/electron#47420,
electron/electron#45416, podman-desktop/podman-desktop#12409). The
esbuild migration's keepNames option (which wraps every function/class
with an Object.defineProperty call) shifted heap layout enough to make
the spec/fixtures/crash-cases/webcontentsview-create-leak-exit case
reliably reproduce it on every run, giving a clean signal for the fix.
Both WrappableBase and DeprecatedWrappableBase SecondWeakCallback now
post the deletion via base::SequencedTaskRunner::GetCurrentDefault()
so the destructor (and any Emit it does) runs once V8 has left the GC
scope. Falls back to synchronous deletion if no task runner is
available (early/late process lifetime).
Fixeselectron/electron#47420.

WebContentsPermissionHelper::CheckPermission was hardcoding
GetPrimaryMainFrame() and deriving the requesting origin from
web_contents_->GetLastCommittedURL(), so the setPermissionCheckHandler
callback always received the top frame's origin and
details.isMainFrame/details.requestingUrl always reflected the main
frame, even when a cross-origin subframe with allow="serial" or
allow="camera; microphone" triggered the check.
Thread the requesting RenderFrameHost through CheckPermission,
CheckSerialAccessPermission, and CheckMediaAccessPermission so the
permission manager receives the real requesting frame. Update the
serial delegate and WebContents::CheckMediaAccessPermission callers to
pass the frame they already have.
Adds a regression test that loads a cross-origin iframe with
allow="camera; microphone", calls enumerateDevices() from within the
iframe, and asserts the permission check handler receives the iframe
origin for requestingOrigin, isMainFrame, and requestingUrl.

fix: resolve getFileHandle concurrent stalling by queuing callbacks (#50597)
Previously, concurrent calls to FileSystemAccessPermissionContext::ConfirmSensitiveEntryAccess
for the same file path would silently discard the subsequent callbacks because
the internal callback map used a single callback per file path and std::map::try_emplace
would drop the callback if the key already existed. This caused Promises in JS
(e.g., dirHandle.getFileHandle()) to stall indefinitely.
This commit updates the callback map to hold a vector of callbacks, so all
concurrent requesters for the same filepath are grouped together and resolved
once the asynchronous blocklist check completes.
Notes: Fixed an issue where concurrent `getFileHandle` requests on the same path could stall indefinitely.

When silent printing with non-default margins (custom, no margins, or
printable area margins), the kFitToPrintableArea scaling option causes
double-marginalization: the custom margins define the content area, then
the scaling additionally fits content to the printer's printable area.
Only apply kFitToPrintableArea when using default margins in silent mode.
For non-default margins, use the same scaling as non-silent prints.

ShowInvalidPrinterSettingsError() called TerminatePrintJob(true),
but when no print_job_ had been created yet (e.g. settings validation

immediately without reaching ReleasePrintJob() where the callback

until WebContents destruction, causing webContents.print() to only
fire its callback when the application closed.
