856027 - Un-hide WindowsXP opt xpcshell tests when the failure rate isn't unacceptably high

Status: RESOLVED FIXED

Description

[Ryan VanderMeulen [:RyanVM]]

Due to the dependencies marked here (primarily bugs 824022 and bug 855269), Windows XP opt xpcshell fails ~50% of the time it runs, which does not meet our standards for a visible by default test suite. I am hiding it on all mozilla-central based trees until the situation is improved.

(Moving to TBPL's component, since that's where the unhiding takes place, and is the component sheriffs watch. Fixing the failure rate to get us to the point where we can unhide is covered by the dependant bugs, which are in the appropriate components)

In case anybody's wondering, we still see these failures on the iX machines as well.

Also, information from bug 824022 that might help:

This had been unhidden by armen a while ago. Armen, please comment in the bug when doing this/file one if it doesn't exist, see: https://wiki.mozilla.org/Sheriffing/Job_Visibility_Policy#Requesting_changes_in_visibility

Though the failure rate has suddenly spiked again today :-/
