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.
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.

* feat: forward activation token from libnotify notification clicks
When a notification action is clicked on Linux, retrieve the activation
token from libnotify (if available) via dlsym and set it using
`base::nix::SetActivationToken()`. This enables proper window focus
handling under Wayland, where the compositor requires a valid activation
token to grant focus to the application.
The `notify_notification_get_activation_token` symbol is resolved at
runtime to maintain compatibility with older libnotify versions that
do not expose this API.

* refactor: simplify libnotify soname loading and activation token lookup
Replace the chained Load() calls with a loop over a constexpr array of
sonames, and inline the lazy EnsureActivationTokenFunc() into
Initialize() since it is only called once and the library handle is
already known at that point.

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.

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.

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.
Fixes#49455

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: 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.
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.

* feat: add macOS-only api to determine if app is currently active

* fix: ensure we hide app after showing in test
If the app is still active, it may affect other tests like dock.bounce
that behave differently depending on whether the app is active
* docs: simplify isActive api description
Enter the destination context scope before creating the VideoFrame V8
wrapper, matching the sibling Element and Blob branches. Without this,
ScriptState::ForCurrentRealm resolved to the calling context instead of
the target context, producing an incorrect wrapper.
Also switch to ScriptState::From with an explicit context argument to
make the intent clearer.
Adds spec coverage for VideoFrame crossing the bridge in both
directions and adds VideoFrame to the existing prototype checks.
* test: add failing test for `setFullscreen(false)`
`setFullscreen(false)` should do nothing
when not already in fullscreen, but it hides the menu bar
on Linux.
* fix: menu bar hiding on two setFullScreen(false)
This fixes the following bug on Linux (and maybe macOS):
1. Create a window with a menu bar.
2. Call `win.setFullScreen(false)`.
The menu bar will hide.
