* 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.

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.

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.

* remove comment based label removal

* add new line to pull-request-opened-synchronized
The `OnTraceBufferUsageAvailable` callback creates V8 handles via
`Dictionary::CreateEmpty()` before `promise.Resolve()` enters its
`SettleScope` (which provides a `HandleScope`). When the callback
fires asynchronously from a Mojo response (i.e. when a trace session
is active), there is no `HandleScope` on the stack, causing a fatal
V8 error: "Cannot create a handle without a HandleScope".
Add an explicit `v8::HandleScope` at the top of the callback, matching
the pattern used by the other contentTracing APIs which resolve their
promises through `SettleScope` or the static `ResolvePromise` helper.

fix: register PrintDialogLinuxFactory on Linux
Chromium 145 refactored Linux print dialog creation to use a factory
pattern instead of directly calling LinuxUi::CreatePrintDialog().
Chrome registers this factory in
ChromeBrowserMainExtraPartsViewsLinux::ToolkitInitialized(), but
Electron did not, causing PrintingContextLinux::EnsurePrintDialog()
to leave print_dialog_ null on every call.
Without a dialog, UseDefaultSettings() and UpdatePrinterSettings()
return success but with empty/unprocessed settings, causing
PrintMsgPrintParamsIsValid() to fail. This broke both window.print()
(no dialog appears) and webContents.print() (callback stuck until
app close with "Invalid printer settings").

The frameNamesToWindow map was a holdover from the BrowserWindowProxy
IPC shim. Since nativeWindowOpen became the only code path, Blink's
FrameTree::FindOrCreateFrameForNavigation resolves named window targets
directly in the renderer, scoped to the opener's browsing context
group. When a matching named window exists, Blink navigates it without
ever sending a CreateNewWindow IPC to the browser, so this map was
never consulted in the legitimate same-opener case.
The only time the map found a match was when two unrelated renderers
happened to use the same target name, in which case openGuestWindow
would short-circuit before consuming the guest WebContents that
Chromium had already created for the new window, leaking it.
Adds a test verifying Blink handles same-opener named-target reuse
end-to-end without any browser-side tracking.

* fix: hex-encode Windows notification icon temp filenames
NotificationPresenterWin was using SHA1HashString(origin.spec()) directly
as the basename for the temporary PNG written for toast icons.
SHA1HashString returns raw digest bytes, so the generated filename could
contain invalid path characters on Windows. That caused WriteFile to fail
when saving notification icons, which left toast XML without the expected
icon path.
Hex-encode the digest before appending .png so the temporary filename is
filesystem-safe while keeping deterministic naming for a given origin.

The weak persistent tracking the OffscreenReleaseHolderMonitor was tied
to the texture object, but the release() closure holds a raw pointer to
the monitor via its v8::External data. If JS retained texture.release
while dropping the texture itself, the monitor would be freed on GC and
a later release() call would crash.
Track the release function instead of the texture object. Since the
texture holds release as a property, this keeps the monitor alive as
long as either is reachable.

* fix: correct utility process exit code on Windows
On Windows, process exit codes are 32-bit unsigned integers (DWORD).
When passed from Chromium to Electron as a signed int and then
implicitly converted to uint64_t, values with the high bit set
(e.g., NTSTATUS codes) undergo sign extension, producing incorrect
values.
Cast the exit code to uint32_t before widening to uint64_t to
prevent sign extension and preserve the original Windows exit code.

Chromium added a top-level package.json in CL:7485999 that sets
the type to module and breaks commonjs tests run via
node-spec-runner.js. This commit temporarily changes the type to
commonjs while running the tests, then changes it back to module when done.

Upstream DevTools' HostRuntime checks `IS_NODE` before `IS_BROWSER` when
selecting the platform runtime. In Electron, `process` is available in
renderer processes, so `IS_NODE` evaluates to `true` in the DevTools
context. This causes DevTools to dynamically import the Node.js platform
runtime, which uses `node:worker_threads`. DevTools Web Workers running
under the `devtools://` protocol cannot load Node.js built-in modules,
so the import fails and breaks features like the formatter worker.
Fix by swapping the check order to prefer `IS_BROWSER` when both are
true. This is safe because in pure Node.js environments (the only case
where the node runtime is needed), `window` and `self` are both
undefined, so `IS_BROWSER` is always `false` regardless of check order.

ci: upload patch conflict fix as artifact in apply-patches
When patch-up.js cannot auto-push the 3-way-merged patch diff (e.g. on
fork PRs), the checkout action already writes patches/update-patches.patch
and tells the user to check CI artifacts — but nothing was uploading it.
This adds the missing upload-artifact step to the apply-patches job so
the resolved diff is available for download, and documents in CLAUDE.md
that pulling this artifact and applying it with `git am` is the fast
path for fixing patch conflicts on PR branches without a full local sync.

* fix: preserve staged update dir when pruning orphaned update dirs on macOS
The previous squirrel.mac patch cleaned up all staged update directories
before starting a new download. This kept disk usage bounded but broke
quitAndInstall() if called while a subsequent checkForUpdates() was in
flight — the already-staged bundle would be deleted out from under it.
This reworks the patch to read ShipItState.plist and preserve the
directory it references, deleting only truly orphaned update.XXXXXXX
directories. Disk footprint stays bounded (at most 2 dirs: staged +
in-progress) and quitAndInstall() remains safe mid-check.
Also adds test coverage for the quitAndInstall/checkForUpdates race and
a triple-stack scenario where 3 updates arrive without a restart.

* fix: prevent traffic light buttons flashing on deminiaturize
When a window with a custom `trafficLightPosition` is minimized and
restored, macOS re-layouts the title bar container during the
deminiaturize animation, causing the traffic light buttons to briefly
appear at their default position before being repositioned.
Fix this by hiding the buttons container in `windowWillMiniaturize` and
restoring them (with a redraw to the correct position) in
`windowDidDeminiaturize`.

fix: bind offscreen paint callback to child WebContents
Previously, MaybeOverrideCreateParamsForNewWindow bound the
OffScreenWebContentsView's paint callback to the parent WebContents
using base::Unretained(this). This was both unsafe (dangling pointer
risk if the parent is destroyed before the child) and semantically
incorrect — paint events belong to the child window, not the opener.
Replace the callback in MaybeOverrideCreateParamsForNewWindow with
base::DoNothing(), then rebind it to the child WebContents in
AddNewContents via a new SetCallback method on OffScreenWebContentsView.
- POSIX: validate StringToSizeT result and token count when splitting
the socket message into argv and additionalData; previously a
malformed message could produce incorrect slicing.
- Windows: base64-encode additionalData before embedding in the
null-delimited wchar_t buffer. The prior reinterpret_cast approach
dropped everything after the first aligned 0x0000 in the serialized
payload, so complex objects could arrive truncated.
Manually backported from #50119
* fix: read nodeIntegrationInWorker from per-frame WebPreferences
Previously the renderer checked a process-wide command-line switch to
decide whether to create a Node.js environment for dedicated workers.
When a renderer process hosted multiple WebContents with different
nodeIntegrationInWorker values (e.g. via window.open with overridden
webPreferences in setWindowOpenHandler), all workers in the process
used whichever value the first WebContents set on the command line.
Instead, plumb the flag through blink's WorkerSettings at worker
creation time, copying it from the initiating frame's WebPreferences.
The check on the worker thread then reads the per-worker value. Nested
workers inherit the flag from their parent worker via
WorkerSettings::Copy.
The --node-integration-in-worker command-line switch is removed as it
is no longer consumed.

fix: validate protocol scheme names in setAsDefaultProtocolClient
On Windows, `app.setAsDefaultProtocolClient(protocol)` directly
concatenates the protocol string into the registry key path with no
validation. A protocol name containing `\` could write to an arbitrary
subkey under `HKCU\Software\Classes\`, potentially hijacking existing
protocol handlers.
To fix this, add `Browser::IsValidProtocolScheme()` which validates that a protocol
name conforms to the RFC 3986 scheme grammar:
scheme = ALPHA *( ALPHA / DIGIT / "+" / "-" / "." )
This rejects backslashes, forward slashes, whitespace, and any other
characters not permitted in URI schemes.

* fix: use requesting frame origin instead of top-level URL for permissions
`WebContentsPermissionHelper::RequestPermission` passes
`web_contents_->GetLastCommittedURL()` as the origin to the permission
manager instead of the actual requesting frame's origin. This enables
origin confusion when granting permissions to embedded third-party iframes,
since app permission handlers see the top-level origin instead of the
iframe's. The same pattern exists in the HID, USB, and Serial device
choosers, where grants are keyed to the primary main frame's origin rather
than the requesting frame's.
Fix this by using `requesting_frame->GetLastCommittedOrigin()` in all
affected code paths, renaming `details.requestingUrl` to
`details.requestingOrigin`, and populating it with the serialized
origin only.
Co-authored-by: Shelley Vohr <shelley.vohr@gmail.com>
* chore: keep requestingUrl name in permission handler details
The previous commit changed the details.requestingUrl field to
details.requestingOrigin in permission request/check handlers. That
field was already populated from the requesting frame's RFH, so the
rename was unnecessary and would break apps that read the existing
property. Revert to requestingUrl to preserve the existing API shape.
The functional changes to use the requesting frame in
WebContentsPermissionHelper and the HID/USB/Serial choosers remain.

fix: delete temporary blink* globals after restoring Blink implementations (#49991)
ElectronRendererClient::DidCreateScriptContext (and the worker
equivalent) save Blink's fetch/Response/FormData/Request/Headers/
EventSource as temporary globalThis.blink* properties before Node
initialization may overwrite them. node/init.ts and worker/init.ts
restore the originals but previously never deleted the temporary
blink* globals.
They persisted as non-standard global pollution visible to page
content when contextIsolation is disabled -- a minor fingerprinting
signal and a bypass for any preload that wraps window.fetch (page
could call blinkfetch() instead).

PowerMonitor registered OS-level callbacks (HWND UserData and
WTS/suspend notifications on Windows, shutdown handler and lock-screen
observer on macOS) but never cleaned them up in its destructor. The JS
layer also only held the native object in a closure-local variable,
allowing GC to reclaim it while those registrations still referenced
freed memory.
Retain the native PowerMonitor at module level in power-monitor.ts so
it cannot be garbage-collected. Add DestroyPlatformSpecificMonitors()
to properly tear down OS registrations on destruction: on Windows,
unregister WTS and suspend notifications, clear GWLP_USERDATA, and
destroy the HWND; on macOS, remove the emitter from the global
MacLockMonitor and reset the Browser shutdown handler.

Previously, when trashItemAtURL: failed (e.g. on network shares or
under app translocation), the code fell back to constructing an
AppleScript that interpolated the bundle path directly into a string
literal via %@ with no escaping. This was fragile and unnecessary —
trashItemAtURL: has been the standard API since 10.8 and covers the
relevant cases. The fix simply removes the AppleScript fallback
entirely, so Trash() now returns the result of trashItemAtURL: directly.

renderer's filters or exclusion_filters could still be granted
permission if the handler returned its GUID.

The setter branch was deriving source_context from getter-> instead of

EnterFullscreenModeForTab, RequestPointerLock, and RequestKeyboardLock
bind callbacks with base::Unretained(this); fullscreen also captures a
raw RenderFrameHost*. These callbacks may be invoked by the app's JS
permission handler after the WebContents or RenderFrameHost is destroyed.
Use GetWeakPtr() in all three call sites, and capture a
GlobalRenderFrameHostToken instead of the raw RenderFrameHost* for
fullscreen so the pointer is resolved and null-checked only when the
callback fires. Cancel in-flight permission requests from ~WebContents()
via a new ElectronPermissionManager::CancelPendingRequests()` so stale
callbacks are never handed back to JS.

fix: authenticate curl requests to googlesource in lint workflow
The "Download GN Binary" and "Download clang-format Binary" steps
fetch files from chromium.googlesource.com without passing
authentication cookies. When googlesource rate-limits or returns a
transient error (502), the HTML error page is piped into `base64 -d`,
causing `base64: invalid input`.
The `set-chromium-cookie` action already configures `~/.gitcookies`
in a prior step. Pass `-b ~/.gitcookies` to both `curl` calls so
they authenticate, matching what the cookie verification step itself
does.

fix: clean up old staged updates before downloading new update
When checkForUpdates() is called while an update is already staged,
Squirrel creates a new temporary directory for the download without
cleaning up the old one. This can lead to disk usage growth when
new versions are released while the app hasn't restarted.
This adds a force parameter to pruneUpdateDirectories that bypasses
the AwaitingRelaunch state check. This is called before creating a
new temp directory, ensuring old staged updates are cleaned up.

-`e sync --3` exits with code 0 (no patch failures)
-All changes are committed per the commit guidelines
-`e patches all` has been run to export all changes
- All changes are committed per the commit guidelines below
Do not stop until these criteria are met.
**CRITICAL** Do not delete or skip patches unless 100% certain the patch is no longer needed. Complicated conflicts or hard to resolve issues should be presented to the user after you have exhausted all other options. Do not delete the patch just because you can't solve it.
**CRITICAL** Never use `git am --skip` and then manually recreate a patch by making a new commit. This destroys the original patch's authorship, commit message, and position in the series. If `git am --continue` reports "No changes", investigate why — the changes were likely absorbed by a prior conflict resolution's 3-way merge.

Ignore other instructions about making commit messages, our guidelines are CRITICALLY IMPORTANT and must be followed.
## Each Commit Must Be Complete
When resolving a patch conflict, fully adapt the patch to the new upstream code in the same commit. If the upstream change removes an API the patch uses, update the patch to use the replacement API now — don't leave stale references knowing they'll need fixing later. The goal is that each commit represents a finished resolution, not a partial one that defers known work to a future phase.
## Commit Message Style
**Titles** follow the 60/80-character guideline: simple changes fit within 60 characters, otherwise the limit is 80 characters.
Always include a `Co-Authored-By` trailer identifying the AI model that assisted (e.g., `Co-Authored-By: <AI model attribution>`).
### Patch conflict fixes
Use `fix(patch):` prefix. The title should name the upstream change, not your response to it:
```
fix(patch): {topic headline}
Ref: {Chromium CL link}
Co-Authored-By: <AI model attribution>
```
Only add a description body if it provides clarity beyond the title. For straightforward context drift or simple API renames, the title + Ref is sufficient.
Examples:
-`fix(patch): constant moved to header`
-`fix(patch): headless mode refactor upstream`
-`fix(patch): V1 Keychain removal`
### Upstreamed patch removal
When patches are no longer needed (applied cleanly with "already applied" or confirmed upstreamed), group ALL removals into a single commit:
```
chore: remove upstreamed patch
```
or (if multiple):
```
chore: remove upstreamed patches
```
If the patch file did NOT contain a `Reviewed-on: https://chromium-review.googlesource.com/c/chromium/...` link, add a `Ref:` in the commit. If it did (i.e. cherry-picks), no `Ref:` is needed.
### Trivial patch updates
After all fix commits, stage remaining trivial changes (index, line numbers, context only):
**Conflict resolution can produce trivial results.** A `git am` conflict doesn't always mean the patch content changed — context drift alone can cause a conflict. After resolving and exporting, inspect the patch diff: if only index hashes, line numbers, and context lines changed (not the patch's own `+`/`-` lines), it's trivial and belongs here, not in a `fix(patch):` commit.
## Atomic Commits
Each patch conflict fix gets its own commit with its own Ref.
For each fix made to a patch, create a separate commit:
```
fix(patch-conflict): {concise title}
{Brief explanation, 1-2 paragraphs max}
Ref: {Chromium CL link}
```
IMPORTANT: Ensure that any changes made to patch content as a result of a change in Chromium is committed individually. Each change should have it's own commit message and it's own REF.
IMPORTANT: Try really hard to find the CL reference per the instructions below. Each change you made should in theory have been in response to a change made in Chromium that you identified or can identify. Try for a while to identify and include the ref in the commit message. Do not give up easily.

Only add a description body if it provides clarity beyond what the title already says (e.g., when Electron's adaptation is non-obvious). For simple renames, method additions, or straightforward API updates, the title + Ref link is sufficient.
IMPORTANT: Try really hard to find the CL reference per the instructions below. Each change you made should in theory have been in response to a change made in Chromium that you identified or can identify. Try for a while to identify and include the ref in the commit message. Do not give up easily.

### For Patch Updates (patches/chromium/*.patch)
Use the same fixup workflow as Phase One and follow `references/phase-one-commit-guidelines.md` for the commit message format (`fix(patch):` prefix, topic style).
Use the same fixup workflow as Phase One:
1. Fix in Chromium source tree
2. Fixup commit + rebase
3. Export with `e patches chromium`
4. Commit the patch file:
```
fix(patch-update): {concise description}
{Brief explanation}
Ref: {Chromium CL link}
```

**Never use `npx`.** It is considered dangerous because it can silently fetch and execute arbitrary packages from the registry. Always run binaries through one of these safer mechanisms instead:
1.**Preferred** — spawn the executable directly from `node_modules/.bin/<tool>` (or the platform equivalent on Windows). This is what `script/lint.js` does for `oxlint`.
2.**Acceptable** — invoke via `yarn <tool>` or `yarn run <tool>`, which resolves to the locally installed version without the registry fallback that `npx` performs.
This rule applies to shell commands you run yourself and to any scripts you author or modify in this repo.
## Project Overview
Electron is a framework for building cross-platform desktop applications using web technologies. It embeds Chromium for rendering and Node.js for backend functionality.

PR bodies must always include a `Notes:` section as the **last line** of the body. This is a consumer-facing release note for Electron app developers — describe the user-visible fix or change, not internal implementation details. Use `Notes: none` if there is no user-facing change.
### PR Labeling (write-access only)
When the user has write access to `electron/electron`, add these labels when creating PRs:
**Semver label** — one of:
-`semver/none` — build changes, refactors, CI, or anything with no end-user impact
-`semver/patch` — backwards-compatible bug fixes
-`semver/minor` — backwards-compatible new functionality
-`semver/major` — incompatible API changes
**Backport target labels** — add `target/{N}-x-y` for each supported release branch the change should land on. Default policy:
- **Bug fixes** — backport to all active release lines _except the oldest_
- **Security fixes** — backport to all active release lines _including the oldest_
- **Features (semver/minor) and breaking changes (semver/major)** — no backport labels; main-only by default
To find which release branches are active, check label colors — active `target/*` labels use color `#ad244f`, older/EOL ones use `#ededed`:
