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: 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.

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.
gfx::PNGCodec::Decode() returns a null SkBitmap when it fails to decode
the clipboard contents as a PNG. Passing that null bitmap to
gfx::Image::CreateFrom1xBitmap() triggers a crash.
Return an empty gfx::Image instead, matching the existing null-check
pattern in skia_util.cc.
GetDefaultPrinterDPI() creates a blank GtkPrintSettings and reads
its resolution, which returns 0 for uninitialized settings. With
DPI=0, SetPrintableAreaIfValid() computes a zero scale factor,
producing empty page dimensions that fail PrintMsgPrintParamsIsValid().
Fall back to kDefaultPdfDpi (72) when GTK returns 0, matching the
existing Windows fallback pattern when CreateDC fails.
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").
* 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.

- export_gin_v8platform_pageallocator_for_usage_outside_of_the_gin.patch:
gin::V8Platform::GetPageAllocator() is now exported upstream via the
public v8::Platform interface, so we no longer need to patch gin to
expose a custom accessor. Update javascript_environment.cc to use the
upstream API instead.
- fix_getcursorscreenpoint_wrongly_returns_0_0.patch: this fix has
landed upstream in Chromium and is no longer needed as a local patch.
* refactor: SafeV8Function to be backed by cppgc
* spec: focus renderer before attempting paste
* spec: remove listeners to prevent leak on failed tests
* fix: lazily initialize safeStorage async encryptor
The SafeStorage constructor previously registered a browser observer that
called os_crypt_async()->GetInstance() on app-ready. Because ESM named
imports (import { x } from 'electron') eagerly evaluate all electron
module getters, simply importing electron in an ESM entrypoint would
construct SafeStorage and touch the OS keychain on app-ready, even when
safeStorage was never used.
This showed up as a macOS CI hang: the esm-spec import-meta fixture
triggers a keychain access prompt that blocks the test runner until
timeout.
Now the async encryptor is requested lazily on the first call to
encryptStringAsync, decryptStringAsync, or isAsyncEncryptionAvailable.
isAsyncEncryptionAvailable now returns a Promise that resolves once
initialization completes, matching what the docs already stated.
* chore: lint
* fix: add HandleScope in OnOsCryptReady for pending operations
OnOsCryptReady fires asynchronously from a posted task without an active
V8 HandleScope. Previously this was harmless because eager init meant the
pending queues were always empty when it fired. With lazy init, operations
queue up first, then the callback processes them and needs to create V8
handles (Buffer::Copy, Dictionary::CreateEmpty, Promise::Resolve).

fix: format video as file url
* test: skip webFrameMain.copyVideoFrameAt on win32 CI due Chromium DCHECK
* 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: narrow HandleTermination and Shutdown to uint32_t, add tests
* feat: support notification priority on Windows
Add Windows notifications support urgency/priority levels.
This maps the existing `urgency` option (previously Linux-only) to
Windows toast notification priorities:
- 'critical' maps to ToastNotificationPriority_High, which sorts the
notification above default-priority items in Action Center.
- 'normal' and 'low' both map to ToastNotificationPriority_Default.
Note that on Windows, 'critical' priority does not prevent the toast
from being auto-dismissed. Users should additionally set `timeoutType`
to 'never' for that behavior.

build: remove macos hittest workaround patch
CL:6574464 changed BridgedContentView::hitTest: to use GetHitTestResult(), which
returns kRootView for any non-null, non-NativeViewHost view — causing
BridgedContentView to absorb all web content mouse events. In BrowserWindow,
content_view_ sits in front of the sibling WebContentsView and covers the full
client area, so it was always found first, breaking all loadURL page interaction.
Fix this by installing a ContentViewTargeterDelegate on content_view_ in
NativeWindowMac::SetContentView that returns nullptr (instead of the view itself)
when no children cover the target point. This makes GetHitTestResult return kOther,
allowing hitTest: to fall through to [super hitTest:] and find
RenderWidgetHostViewCocoa. This also removes the now-unnecessary chromium
partial-revert patch that worked around the same issue.
refactor: replace CHILD_PLUGIN with CHILD_EMBEDDER_FIRST on macOS
Chromium removed upstream support for child plugin processes without
library validation in https://crbug.com/461717105, which we patched
back via feat_restore_macos_child_plugin_process.patch.
Chromium's CHILD_EMBEDDER_FIRST mechanism already provides the right
extensibility point for this: values > CHILD_EMBEDDER_FIRST are reserved
for embedders and resolved via ContentBrowserClient::GetChildProcessSuffix().
Chrome itself uses this pattern for its Alerts helper process.
This commit replaces the Chromium patch with an Electron-native
implementation.

* fix: prevent traffic light buttons flashing on deminiaturize
When a window with a custom `trafficLightPosition` is minimized and

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: 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.
* 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.

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.
