The WinSboxNoFakeGdiInit feature requires delayload of all DLLs that
might load user32.dll in the renderer process. It's enabled as a field
trial for all non-Official builds, but appears to only work with
non-component Release builds. See https://crbug.com/326277735
OnBeforeClose notification is delivered via TabModel destruction in
TabStripModel::SendDetachWebContentsNotifications. We need to let
that call stack unwind before triggering TabStripModel destruction
via closure of the native host window.
Chrome runtime only supports creation of a Views-hosted DevTools
popup in ChromeBrowserDelegate::CreateDevToolsBrowser if the parent
is also Views-hosted.
To test:
- Run `cefclient --use-native`
- Right click, select "Show DevTools"
- Close both windows and the app should exit
Compatible configurations include:
- Non-component builds.
- Debug builds on Mac/Linux.
- Release builds on Windows (b/c Debug builds require component builds).
- ASAN builds (which are also Release builds).
See related logic in //build_overrides/partition_alloc.gni
Now that args.gn is an input to the make_config_header target we
don't want to invalidate the build unnecessarily by modifying the
file if the contents are unchanged.
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.
Include cef_config.h from base/cef_build.h and fix detection of
args.gn changes so that defines are available everywhere by default.
Fix include configuration for chrome_elf_set and sandbox targets.
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.
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]`
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.
Starting with Python 3.12, use of invalid escape sequences in strings
is reported as a SyntaxWarning and will become a SyntaxError at a
later point.
Regular expressions use the backslash character a lot, which result in
warnings of this kind. Python docs recommend to generally use raw
strings for this purpose.
