Also enables logging by default for Release builds (previously
required the `--enable-logging` flag). Logging can still be
disabled by passing the `--disable-logging` flag.
To test:
- Run `cefclient --enable-chrome-runtime --use-alloy-style
--use-chrome-style-window [--background-color=green]`
- OS and Chrome theme changes behave as expected.
Set enable_alloy_bootstrap=false to build with Alloy bootstrap code
removed. Extension API is documented as deprecated in comments but
not compiled out with this arg.
This is no longer required now that we have implicit exclusion
of certain frame types including guest view frames.
Rename GuestView to ExcludedView in the renderer process.
Split the Alloy runtime into bootstrap and style components. Support
creation of Alloy style browsers and windows with the Chrome runtime.
Chrome runtime (`--enable-chrome-runtime`) + Alloy style
(`--use-alloy-style`) supports Views (`--use-views`), native parent
(`--use-native`) and windowless rendering
(`--off-screen-rendering-enabled`).
Print preview is supported in all cases except with windowless rendering
on all platforms and native parent on MacOS. It is disabled by default
with Alloy style for legacy compatibility. Where supported it can be
enabled or disabled globally using `--[enable|disable]-print-preview` or
configured on a per-RequestContext basis using the
`printing.print_preview_disabled` preference. It also behaves as
expected when triggered via the PDF viewer print button.
Chrome runtime + Alloy style behavior differs from Alloy runtime in the
following significant ways:
- Supports Chrome error pages by default.
- DevTools popups are Chrome style only (cannot be windowless).
- The Alloy extension API will not supported.
Chrome runtime + Alloy style passes all expected Alloy ceftests except
the following:
- `DisplayTest.AutoResize` (Alloy extension API not supported)
- `DownloadTest.*` (Download API not yet supported)
- `ExtensionTest.*` (Alloy extension API not supported)
This change also adds Chrome runtime support for
CefContextMenuHandler::RunContextMenu (see #3293).
This change also explicitly blocks (and doesn't retry) FrameAttached
requests from PDF viewer and print preview excluded frames (see #3664).
Known issues specific to Chrome runtime + Alloy style:
- DevTools popup with windowless rendering doesn't load successfully.
Use windowed rendering or remote debugging as a workaround.
- Chrome style Window with Alloy style BrowserView (`--use-alloy-style
--use-chrome-style-window`) does not show Chrome theme changes.
To test:
- Run `ceftests --enable-chrome-runtime --use-alloy-style
[--use-chrome-style-window] [--use-views|--use-native]
--gtest_filter=...`
- Run `cefclient --enable-chrome-runtime --use-alloy-style
[--use-chrome-style-window]
[--use-views|--use-native|--off-screen-rendering-enabled]`
- Run `cefsimple --enable-chrome-runtime --use-alloy-style [--use-views]`
The call to SelectNativeTheme from ChromeBrowserFrame::Initialized was
causing Widget::ThemeChanged reentrancy via OnColorProviderCacheResetMissed
when running with `--enable-chrome-runtime --use-native`. Make all calls to
ThemeChanged async to avoid this and possible future issues.
Controls now respect OS and Chrome themes by default for both Alloy
and Chrome runtimes. Chrome themes (mode and colors) can be configured
using the new CefRequestContext::SetChromeColorScheme method. Individual
theme colors can be overridden using the new CefWindowDelegate::
OnThemeColorsChanged and CefWindow::SetThemeColor methods.
The `--force-light-mode` and `--force-dark-mode` command-line flags are
now respected on all platforms as an override for the OS theme.
The current Chrome theme, if any, will take precedence over the OS theme
when determining light/dark status. On Windows and MacOS the titlebar
color will also be updated to match the light/dark theme.
Testable as follows:
- Run: `cefclient --enable-chrome-runtime` OR
`cefclient --use-views --persist-user-preferences --cache-path=...`
- App launches with default OS light/dark theme colors.
- Change OS dark/light theme under system settings. Notice that theme
colors change as expected.
- Right click, select items from the new Theme sub-menu. Notice that
theme colors behave as expected.
- Exit and relaunch the app. Notice that the last-used theme colors are
applied on app restart.
- Add `--background-color=green` to above command-line.
- Perform the same actions as above. Notice that all controls start
and remain green throughout (except some icons with Chrome runtime).
- Add `--force-light-mode` or `--force-dark-mode` to above command-line.
- Perform the same actions as above. Notice that OS dark/light theme
changes are ignored, but Chrome theme changes work as expected.
The client can optionally wait or terminate the render process.
Expose process exit codes via OnRenderProcessTerminated and
CefGetExitCode (fixes#2126).
cefclient: Add a new https://tests/hang page for testing hang behavior.
cefclient: Move message and resource handling to a new BaseClientHandler
class to support loading of test pages in default Chrome UI windows.
Selecting a new user or incognito profile via Chrome UI may result in
the creation of a new Profile object. If that occurs, we should find
or create a matching CefBrowserContext and CefRequestContext instead
of reusing an existing mismatched context (e.g. using the original
context for an incognito window would be a mismatch). If a new
CefRequestContext will be created the client can now implement
CefBrowserProcessHandler::GetDefaultRequestContextHandler() to
provide the handler for that context.
To test with a new user profile:
1. Click "Profile" icon, select "Add". Now you have 2+ profiles.
2. Click "Profile" icon, select the other user name to create a new
window using the other user profile.
3. The new window should launch successfully.
To test with a new incognito profile:
1. Select "New Incognito window" from the 3-dot menu.
2. The new window should launch successfully.
To test DevTools window creation for the new profile:
1. Right-click in the new window, select Inspect.
2. The DevTools window should launch successfully.
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.
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.
When running ceftests with Views enabled always close the CefWindow
when the browser is destroyed and wait for both CefBrowser and
CefWindow destruction before signaling test completion.
To test:
Run `ceftests --enable-chrome-runtime --use-views
--gtest_filter=FrameHandlerTest.OrderMainPopup*:RequestContextTest.PopupNavDestroyParent*`
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.
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.
Chrome is always loading the primary user profile by default, so with this
change the CEF behavior more accurately reflects reality. Incognito contexts
can still be created explicitly via CefRequestContext::CreateContext.
Prior to this change, the default for the global context was an Incognito
profile based on the primary user profile. That caused request interception
to be bypassed in WillCreateURLLoaderFactory for profiles associated with
the "New window" and "New incognito window" commands. Those profiles, while
also being (or based on) the primary user profile, did not match the specific
Incognito profile assigned to the default global context.
After this change, the "New window" and "New incognito window" commands will
match the default global context when executed on a browser that was created
using the primary user profile.
Note: In current master (based on M111), document PiP partially works when
run with the `--enable-features=DocumentPictureInPictureAPI` command-line
flag. However, the document PiP implementation at this Chromium version is
missing fixes that have already been cherry-picked to the 5563 release
branch. Those fixes will only be available in master after the next Chromium
update (to M112).
