1188707 - Gtk3 support causes intermittent test failures (crashes) for WebRTC

Status: RESOLVED FIXED

(Core :: Widget: Gtk, defect)

Description

[Nils Ohlmeier [:drno]]

Revision 05f6b5bc5b4b on mozilla-central seems to intermittent test failures for all kind of WebRTC tests.

Examples:
https://treeherder.mozilla.org/logviewer.html#?job_id=9714702&repo=try
https://treeherder.mozilla.org/logviewer.html#?job_id=9708346&repo=try
https://treeherder.mozilla.org/logviewer.html#?job_id=9842902&repo=try

As discussed briefly here https://bugzilla.mozilla.org/show_bug.cgi?id=1180000#c218 these problems seem to dis-appear if I rebase on the revision before 05f6b5bc5b4b.

Note: this does not appear to depend on the changes in bug 1180000 as the third log is from bug 1188120.

Mike as you were the one who landed GTK3 support, can you help us figure out what is blocking us here from re-enabling our WebRTC tests or refer to someone who can help us with that?

You need gtk debug symbols installed on test slaves for those crash reports to be more useful. I think there's an open bug for that but I can't find it.

Has the situation improved with this lately? We have made several fixes in the area of GTK and thread-safety that might have resolved this issue.

Yes we haven't seen much of the crashes any more.
