This avoids a situation where misbehaving clients may cause the
application to continue running indefinitely by posting new UI
thread tasks after calling CefQuitMessageLoop.
Running `cefsimple --enable-chrome-runtime` will create and run a
Chrome browser window using the CEF app methods, and call
CefApp::OnContextInitialized as expected. CEF task methods also
work as expected in the main process. No browser-related methods or
callbacks are currently supported for the Chrome window, and the
application will exit when the last Chrome window closes.
The Chrome runtime requires resources.pak, chrome_100_percent.pak
and chrome_200_percent.pak files which were not previously built
with CEF. It shares the existing locales pak files which have been
updated to include additional Chrome-specific strings.
On Linux, the Chrome runtime requires GTK so use_gtk=true must be
specified via GN_DEFINES when building.
This change also refactors the CEF runtime, which can be tested in
the various supported modes by running:
$ cefclient
$ cefclient --multi-threaded-message-loop
$ cefclient --external-message-pump
CefContext implements the public CEF API functions and delegates
the stages of content & service_manager process execution to
CefMainRunner. CEF-specific runtime logic (which may be replaced
with chrome-specific runtime logic) is then delegated to
CefMainDelegate which implements content::ContentMainDelegate.
