- Adds `--initial-show-state=hidden` support for cefclient and cefsimple
where the window launches as initially hidden (no dock thumbnail).
- Adds `--hide-window-on-close` support for cefclient where clicking the
red traffic light button hides the window instead of closing it.
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.
- chrome: Disable upgrade/downgrade behavior (see #3608)
- chrome: Disable process singleton behavior (see #3609)
- chrome: Disable config as default system browser (see #3613)
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.
Disable Chrome policy management by default. Add CefSettings.chrome_policy_id
which, when configured, enables Chrome policy management. See
https://support.google.com/chrome/a/answer/9037717 for background.
To test:
- Start with a machine where Google Chrome is managed.
- Run `cefclient --enable-chrome-runtime --url=chrome://policy/`
There should be no configured policies.
- Run `cefclient --enable-chrome-runtime --url=chrome://policy/
--enable-chrome-policy`
Configured Platform properties should match Google Chrome.
- Run `cefclient --enable-chrome-runtime --url=chrome://policy/
--enable-chrome-policy --enable-chrome-browser-cloud-management`
Configured Platform and Cloud properties should match Google Chrome.
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.
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.
Use pointers to incomplete struct types. If an argument of a not suitable
type is passed to a function of any string collection,
C compiler will warn:
warning: passing argument 1 of <func> from incompatible pointer type
C++ compiler will raise an error, for example:
error: cannot convert 'cef_string_list_t' ... to 'cef_string_multimap_t'
With the previously used `void*` pointer types, such errors in a code were not
diagnosed.
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 CefSettings cookie scheme configuration will now only impact the global
request context. Custom behavior for other request contexts must now be
configured via CefRequestContextSettings.
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.
