Use ScreenWin functions to correctly compute DIP/pixel conversions for
CEF-created top-level windows.
Fix incorrect DIPToScreenRect usage in DesktopWindowTreeHostWin when
|has_external_parent_| is true.
Change the default stack size to 8 MiB for 64-bit and 0.5 MiB for 32-bit.
CEF's main thread needs at least a 1.5 MiB stack size in order to avoid
stack overflow crashes. However, if this is set in the PE file then other
threads get this size as well, leading to address-space exhaustion in 32-bit
CEF. A new CefRunWinMainWithPreferredStackSize function uses fibers to switch
the main thread to a 4 MiB stack (roughly the same effective size as the
64-bit build's 8 MiB stack) before running any other code.
This change additionally moves the existing Windows-only functions
CefSetOSModalLoop and CefEnableHighDPISupport from cef_app.h to cef_win.h.
On Windows these new CefDisplay methods convert between screen pixel coordinates
and screen DIP coordinates. On macOS and Linux these methods just return a copy
of the input coordinates.
This service is required by the "PermissionOnDeviceNotificationPredictions"
feature which is enabled by default in https://crbug.com/1350956. It uses a
Google backend service as described at https://go.dev/solutions/google/chrome.
This change removes the usage of PredictionBasedPermissionUiSelector, which
triggered this dependency, along with related startup complexity that was added
to support the optimization/prediction service in the M106 update.
Send a FrameDetached message from CefFrameHostImpl::Detach before closing
the RenderFrame connection to avoid an immediate reconnect attempt by the
renderer.
When BFCache is disabled the intentionally detached frame will never be
reconnected. When BFCache is enabled the intentionally detached frame will
be reconnected via CefFrameImpl::OnWasShown if/when it exits the cache.
Run with "--vmodule=frame_*=1 --enable-logging=stderr --no-sandbox" on the
command-line to see these log messages from both the browser and renderer
processes.
Disable BackForwardCache globally for the Alloy runtime so that
blink::RuntimeEnabledFeatures::BackForwardCacheEnables reports the
correct value in the renderer process.
DesktopWindowTreeHostWin ("Chrome_WidgetWin_0") focus needs to be set before
the associated call to WebContents::Focus. In the case of mouse click events,
this means ::SetFocus needs to be called explicitly. See updated comments in
CefBrowserPlatformDelegateNativeWin::SetFocus.
DesktopWindowTreeHostWin ("Chrome_WidgetWin_0") focus needs to be set
synchronously in response to the parent window WM_SETFOCUS message and
before the associated call to WebContents::Focus. See updated comments in
CefBrowserPlatformDelegateNativeWin::SetFocus.
Using a source_set here keeps the linker on Windows from discarding exported
compilation units that are not directly called from inside libcef_static.
This may also fix linker errors on Linux due to CEF's use of an intermediate
static library (see https://crbug.com/1319006#c2).
CefSharedProcessMessageBuilder supports creation of a CefProcessMessage
backed by a CefSharedMemoryRegion.
Performance tests comparing the existing ArgumentList approach and the new
SharedMemoryRegion approach have been added to cefclient at
http://tests/ipc_performance.
CefMessageRouter has been updated to use SharedMemoryRegion as transport
for larger message payloads. The threshold is configurable via
|CefMessageRouterConfig.message_size_threshold|.
To test:
run `ceftests --gtest_filter=SendSharedProcessMessageTest.*:SharedProcessMessageTest.*:MessageRouterTest.Threshold*`
Popup windows will be created on the display that best matches the requested
coordinates. The requested size will apply to the content area (as required by
JS documentation) and window size will be reduced if necessary to fit within the
target display. The requested origin will apply to the window (including frame)
and will be modified if necessary so that the window is fully visible on the
target display.
This change does not implement popup positioning for cefclient which uses an
application-created parent window.
This change grants access to the getScreenDetails JS API without user prompt.
When bfcache is disabled use the RenderFrameObserver::DidFinishLoad notification
instead of the DidStopLoading notification that originates from the browser
process. During fast navigation the DidStopLoading notification may arrive in
the renderer after a new navigation has commenced and cause the wrong regions to
be reported.
