Adds new CefDisplayHandler::OnContentsBoundsChange and
CefDisplayHandler::GetRootWindowScreenRect callbacks.
cefclient: Implement the above callbacks and call
CefBrowserHost::NotifyScreenInfoChanged when the root window
bounds change.
cefclient: osr: Use real screen bounds by default. Pass
`--fake-screen-bounds` for the old default behavior.
Load https://tests/window in cefclient for additional
implementation details and usage examples.
Allow Document picture-in-picture moveTo/By() and resizeTo/By()
(without user gesture) if the new
CefBrowserViewDelegate::AllowMoveForPictureInPicture callback
returns true.
- Use ResetWithReason to report intentional browser side disconnects of
existing Mojo connections. Don't retry for those disconnects.
- Add set_disconnect_with_reason_and_result_handler in Chromium/Mojo to
expose the MojoResult code for failed connections, allowing
identification of connections that are intentionally unbound on the
browser side.
- Optimize initial reconnect delay for known disconnect cases such as
navigation-related and bfcache changes.
- Remove connection timeout and increase total connection deadline by
100% to further reduce crash rates on slower machines.
- Only fail fatally for main frames (not sub-frames) in cases where the
connection fails or disconnects for unknown reasons.
- Improve connection debug logging when running with
`--enable-logging --vmodule=*frame*=1 --log-file=C:\temp\log.txt`
Pass a new |popup_id| parameter to OnBeforePopup and call a new
OnBeforePopupAborted callback if the popup is aborted before
OnAfterCreated is called for the popup browser. Add new
CefBrowserHost::GetBrowserByIdentifier and GetOpenerIdentifier
methods to assist with retrieval of associated browsers.
In cefclient, clean up state when a popup is aborted and close
any associated popup browsers when the opener browser is closed.
This also works when running with `--use-default-popup`.
These linker errors impact CEF builds but not Chromium builds due
to differences in application structure, and are becoming more
common with ongoing Chromium code refactoring.
When running via ASAN it may be necessary to set
`ASAN_OPTIONS=detect_odr_violation=0` to work around

Some downloaded file types [1] default to opening in a Browser. Open
requests for these file types originating from the Download bubble UI
should route to the source Browser (call OnOpenURLFromTab). If
OnOpenURLFromTab is unhandled proceed with the default Chrome behavior
of opening the URL in a new default Browser.
[1] PDF, html, etc. For the complete list of file types see
ChromeDownloadManagerDelegate::IsOpenInBrowserPreferredForFile.
This avoids a bug in clang + MSVC STL when using the default three-way
comparison operator with base::TimeDelta. The compiler does not throw
away the function call to the `std::_Literal_zero_is_expected` symbol,
which is deliberately undefined.

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.
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.
Adds support for the OnAcceleratedPaint callback. Verified to work
on macOS and Windows. Linux support is present but not implemented
for cefclient, so it is not verified to work.
To test:
Run `cefclient --off-screen-rendering-enabled --shared-texture-enabled`
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]`
