- Generated files are now created when running cef_create_projects or
the new version_manager.py tool. These files are still created in the
cef/ source tree (same location as before) but Git ignores them due to
the generated .gitignore file.
- API hashes are committed to Git as a new cef_api_versions.json file.
This file is used for both code generation and CEF version calculation
(replacing the previous usage of cef_api_hash.h for this purpose).
It will be updated by the CEF admin before merging breaking API
changes upstream.
- As an added benefit to the above, contributor PRs will no longer
contain generated code that is susceptible to frequent merge conflicts.
- From a code generation perspective, the main difference is that we now
use versioned structs (e.g. cef_browser_0_t instead of cef_browser_t)
on the libcef (dll/framework) side. Most of the make_*.py tool changes
are related to supporting this.
- From the client perspective, you can now define CEF_API_VERSION in the
project configuration (or get CEF_EXPERIMENTAL by default). This
define will change the API exposed in CEF’s include/ and include/capi
header files. All client-side targets including libcef_dll_wrapper
will need be recompiled when changing this define.
- Examples of the new API-related define usage are provided in
cef_api_version_test.h, api_version_test_impl.cc and
api_version_unittest.cc.
To test:
- Run `ceftests --gtest_filter=ApiVersionTest.*`
- Add `cef_api_version=13300` to GN_DEFINES. Re-run configure, build and
ceftests steps.
- Repeat with 13301, 13302, 13303 (all supported test versions).
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.
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 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.
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.
- 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.
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.
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).
- 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)
