Subject: allow_nested_error_trackers.patch
|
|
|
|
|
|
|
|
|
|
Only one X11ErrorTracker should exist at a time, but upstream has a bug
|
|
|
|
|
where two can exist if running in headless mode --
|
|
|
|
|
ui::(anonymous namespace)::SupportsEWMH() [inner tracker is created]
|
|
|
|
|
ui::WmSupportsHint()
|
|
|
|
|
ui::IsX11WindowFullScreen()
|
|
|
|
|
ui::ScreensaverWindowFinder::IsScreensaverWindow()
|
|
|
|
|
ui::ScreensaverWindowFinder::ShouldStopIterating()
|
|
|
|
|
ui::EnumerateTopLevelWindows()
|
|
|
|
|
ui::ScreensaverWindowFinder::ScreensaverWindowExists() [outer tracker created]
|
|
|
|
|
ui::CheckIdleStateIsLocked()
|
|
|
|
|
ui::CalculateIdleState()
|
|
|
|
|
Removal of either tracker could have side-effects in some code paths,
|
|
|
|
|
so this is probably better handled upstream. This patch tries to do the
|
|
|
|
|
least harm in the interim by removing the check that prevents more than
|
|
|
|
|
one tracker from existing at a time.
