Frame identifiers have changed from int64_t to string type. This is due
to https://crbug.com/1502660 which removes access to frame routing IDs
in the renderer process. New cross-process frame identifiers are 160-bit
values (32-bit child process ID + 128-bit local frame token) and most
easily represented as strings. All other frame-related expectations and
behaviors remain the same.
Executes CefBrowserProcessHandler::OnAlreadyRunningAppRelaunch
callback for when an already running app is relaunched with the
same CefSettings.root_cache_path.
Adds "Root Cache Path" value and related explainer text to
chrome://version.
Adds a LOG(WARNING) that will be output on startup if
CefSettings.root_cache_path is unset in the client app.
Adds a new CefBrowserProcessHandler::OnAlreadyRunningAppRelaunch
callback for when an already running app is relaunched with the
same CefSettings.root_cache_path.
Client apps should check the CefInitialize() return value for early
exit of the relaunch source process.
Add new CefBrowserHost::[Can]ExecuteChromeCommand methods for executing
arbitrary Chrome commands.
Add support for existing CefBrowserHost::ShowDevTools, CloseDevTools and
HasDevTools methods.
DevTools windows now support the same Views callbacks as normal popup
windows with the new CefLifeSpanHandler::OnBeforeDevToolsPopup callback
as the DevTools-specific equivalent of OnBeforePopup.
Always create DevTools as an undocked window to support use of
ShowDevTools with default Chrome browser windows.
To test:
Run `ceftests --enable-chrome-runtime [--use-views]
--gtest_filter=V8Test.OnUncaughtExceptionDevTools`
OR:
1. Run `cefclient --enable-chrome-runtime [--use-native]`
2. Select "Show DevTools", "Close DevTools" or "Inspect" from the
right-click menu.
3. Notice that the DevTools window is Views-hosted (or native-hosted)
and works as expected.
Add --use-default-popup to get a default styled popup in step 3.
Write access to the shared memory region is required because JavaScript lacks
the capability to create read-only ArrayBuffers. When a user attempts to modify
an ArrayBuffer that utilizes a ReadOnlySharedMemoryRegion as its BackingStore
it triggers an access violation.
Note that this pull request may be reverted in the future if JavaScript adds
read-only ArrayBuffer support.
Add a simpler CanZoom/Zoom API as an alternative to the more error-prone
SetZoomLevel/GetZoomLevel API. Both APIs are now implemented for both runtimes.
With the Chrome runtime a zoom notification bubble will be displayed unless
CefBrowserSettings.chrome_zoom_bubble is set to STATE_DISABLED.
To test:
- Run cefclient and select zoom entries from the Tests menu.
- chrome: Run cefclient with `--hide-chrome-bubbles` command-line flag to hide
the zoom notification bubble.
Use the same code path for all fullscreen transitions so that Chrome UI updates
correctly. All user-initiated fullscreen transitions now result in
CefWindowDelegate::OnWindowFullscreenTransition callbacks.
A modal dialog is a child CefWindow that implements some special behaviors
relative to a parent CefWindow. Like any CefWindow it can be framed with
titlebar or frameless, and optionally contain draggable regions (subject to
platform limitations described below). Modal dialogs are shown centered on
the parent window (inside a single display) and always stay on top of the
parent window in z-order. Sizing behavior and available window buttons are
controlled via the usual CefWindowDelegate callbacks. For example, the dialog
can have a preferred size with resize, minimize and maximize disabled (via
GetPreferredSize, CanResize, CanMinimize and CanMaximize respectively).
This change adds support for two modality modes. With window modality all
controls in the parent window are disabled. With browser modality only the
browser view in the parent window is disabled.
Both modality modes require that a valid parent window be returned via
GetParentWindow. For window modality return true from IsWindowModalDialog
and call CefWindow::Show. For browser modality return false from
IsWindowModalDialog (the default value) and call
CefWindow::ShowAsBrowserModalDialog with a reference to the parent window's
browser view.
Window modal dialog behavior depends on the platform. On Windows and
Linux these dialogs have a titlebar and can be moved independent of the
parent window. On macOS these dialogs do not have a titlebar, move with
the parent window, and do not support draggable regions (because they are
implemented using sheets). On Linux disabling the parent window controls
requires a window manager the supports _NET_WM_STATE_MODAL.
Browser modal dialog behavior is similar on all platforms. The dialog will
be automatically sized and positioned relative to the parent window's
browser view. Closing the parent window or navigating the parent browser
view will dismiss the dialog. The dialog can also be moved independent of
the parent window though it will be recentered when the parent window
itself is resized or redisplayed. On MacOS the dialog will move along with
the parent window while on Windows and Linux the parent window can be moved
independently.
To test: Use the Tests > Dialog Window menu option in cefclient with Views
enabled (`--use-views` or `--enable-chrome-runtime` command-line flag).
Browser modal dialog is the default behavior. For window modal dialog add
the `--use-window-modal-dialog` command-line flag.
This change replaces existing CefSettings.user_data_path usage with
CefSettings.root_cache_path for better alignment with the Chrome runtime.
All files should now be written inside the root_cache_path directory.
This adds support for the three-finger-swipe navigation gesture with
Alloy/Views. The default implementation matches the Chrome runtime
and navigates the browser back/forward. We also add an Alloy/Views-
specific client callback in CefBrowserViewDelegate for optional
custom handling of the gesture event.
This change adds new CefCommandHandler callbacks for optionally hiding
specific Chrome toolbar icons, buttons and app menu items.
To test: Run `cefclient --enable-chrome-runtime --filter-chrome-commands`.
Most icons, buttons and app/context menu items will be hidden.
The CefFrame::CreateURLRequest method is no longer supported in the renderer
process. Usage of this method was already limited to same-origin requests due
to renderer process CORS restrictions, and the underlying Blink API has now
been removed in https://crbug.com/1413912 (M112+).
Existing alternatives include CefURLRequest usage in the browser process, or
JavaScript XMLHttpRequest/fetch API usage in the renderer process.
Frameless windows now display as expected. Default traffic light buttons can
optionally be shown at configurable vertical position. Layout respects text
direction.
- mac: Xcode 14.0 with macOS SDK 13.0 is now required.
- Remove CefRequestHandler::OnQuotaRequest because persistent quota is no
longer supported (see https://crbug.com/1208141)
The cefclient sample app on Windows will persist window state across application
restart if run with cache_path and persist_user_references enabled.
To test:
1. Run `cefclient --cache-path=/path/to/cache --persist-user-preferences`
2. Move or resize the window, maximize, minimize, etc.
3. Exit cefclient.
4. Run cefclient again with the same arguments. The previous window state will
be restored.
The cefclient sample app will persist window state across application restart
if run with views, cache_path and persist_user_references enabled.
To test:
1. Run `cefclient --use-views --cache-path=/path/to/cache --persist-user-preferences`
2. Move or resize the window, maximize, minimize, etc.
3. Exit cefclient.
4. Run cefclient again with the same arguments. The previous window state will
be restored.
Custom global and request context preferences can now be registered via
CefBrowserProcessHandler::OnRegisterCustomPreferences. CefRequestContext
now extends CefPreferenceManager and global preferences can be accessed
via CefPreferenceManager::GetGlobalPreferenceManager.
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.
