Existing UI thread shutdown tasks need to be executed before the UI
thread RunLoop is terminated. Those tasks have now been moved to
CefMainRunner::StartShutdownOnUIThread and FinishShutdownOnUIThread is
now called after the RunLoop is terminated.
This fixes a shutdown crash in ChromeProcessSingleton::DeleteInstance.
DeleteInstance needs to be called on the UI thread near the end of the
shutdown process (after ChromeProcessSingleton::Cleanup is called via
PostMainMessageLoopRun).
This service is required by the "PermissionOnDeviceNotificationPredictions"
feature which is enabled by default in https://crbug.com/1350956. It uses a
Google backend service as described at https://go.dev/solutions/google/chrome.
This change removes the usage of PredictionBasedPermissionUiSelector, which
triggered this dependency, along with related startup complexity that was added
to support the optimization/prediction service in the M106 update.
Widevine CDM binaries will be downloaded on supported platforms shortly after
application startup. Widevine support will then become available within a few
seconds after successful installation on Windows or after the next application
restart on other platforms. The CDM files will be downloaded to a "WidevineCdm"
directory inside the `CefSettings.user_data_path` directory.
Pass the `--disable-component-update` command-line flag to disable Widevine
download and installation. Pass the `--component-updater=fast-update` command-
line flag to force Widevine download immediately after application startup.
See the related issue for additional usage details.
As part of introducing the Chrome runtime we now need to distinguish
between the classes that implement the current CEF runtime and the
classes the implement the shared CEF library/runtime structure and
public API. We choose the name Alloy for the current CEF runtime
because it describes a combination of Chrome and other elements.
Shared CEF library/runtime classes will continue to use the Cef
prefix. Classes that implement the Alloy or Chrome runtime will use
the Alloy or Chrome prefixes respectively. Classes that extend an
existing Chrome-prefixed class will add the Cef or Alloy suffix,
thereby following the existing naming pattern of Chrome-derived
classes.
This change applies the new naming pattern to an initial set of
runtime-related classes. Additional classes/files will be renamed
and moved as the Chrome runtime implementation progresses.
