Bug 186679 – [GTK] Layout test media/video-currentTime-delay.html sometimes crashes

• Status: RESOLVED
• Resolution: FIXED
• Component: Media

[Michael Catanzaro]

Layout test media/video-currentTime-delay.html sometimes dies without leaving a backtrace. Sometimes, but not always, it prints an X Window System error:

STDERR: 
STDERR: (WebKitWebProcess:3594): Gdk-ERROR **: The program 'WebKitWebProcess' received an X Window System error.
STDERR: This probably reflects a bug in the program.
STDERR: The error was 'BadAccess (attempt to access private resource denied)'.
STDERR:   (Details: serial 7351 error_code 10 request_code 130 (MIT-SHM) minor_code 1)
STDERR:   (Note to programmers: normally, X errors are reported asynchronously;
STDERR:    that is, you will receive the error a while after causing it.
STDERR:    To debug your program, run it with the GDK_SYNCHRONIZE environment
STDERR:    variable to change this behavior. You can then get a meaningful
STDERR:    backtrace from your debugger if you break on the gdk_x_error() function.)

This is now timing out as well. The diff doesn't provide much info:

I see a failure in 0.3% of cases in debug and 0.2% in release mode. Bots seem to be happy.

This test was marked as a flakey Crash and Timeout in text expectations:

media/video-currentTime-delay.html [ Crash Pass Timeout ]

The test has been constantly passing in the last 1000 revisions. There was a single text failure in WebKitGTK though.

https://results.webkit.org/?suite=layout-tests&test=media%2Fvideo-currentTime-delay.html&platform=GTK&platform=WPE&limit=1000

I'm marking the bug as resolved.

Test removed from test expectations in r287490.
