I had to tun restartTests/testAddons_changeTheme/ for bug 786306 and found that when runned with mozmill-restart it hangs the test running indefinitely(I gave up waiting for it after about 2 hours) The test executes test2.js up until the Theme pane in the Addons Manager and then it does nothing. Tried with different mozmill versions lower than 1.5.19, and they all hanged. So figured it is a Nightly bug. The regression range is: last good: http://hg.mozilla.org/mozilla-central/rev/80499f04e875 http://ftp.mozilla.org/pub/mozilla.org/firefox/nightly/2012-09-19-03-06-02-mozilla-central/ first bad: http://hg.mozilla.org/mozilla-central/rev/1e56d3016820 http://ftp.mozilla.org/pub/mozilla.org/firefox/nightly/2012-09-20-03-05-43-mozilla-central/ pushlog: http://hg.mozilla.org/mozilla-central/pushloghtml?fromchange=80499f04e875&tochange=1e56d3016820 Haven't checked yet if other tests hang.

Which platforms are affected by this bug? Can you please check if there are still tinderbox builds available we could use to narrow it down even further? I would suspect so.

Windows and Mac OSX seem to be unaffected.

The regression range on tinderbox isn't of much help. The changest responsible is the one dealing with the merge, so we still have 114 hidden changes http://hg.mozilla.org/mozilla-central/pushloghtml?fromchange=80499f04e875&tochange=0c8ac138706e

Huh, you have to continue with tinderbox builds for inbound. Those are all present on FTP too. Otherwise I'm not sure why you are making this assumption.

I have added an IT ticket for Softvision side to solve so that we can get a machine with the required configuration here in Romania as soon as possible.

Talking more with Dave, we've been able to narrow this down. It happens when startUserShutdown is used. To reproduce, just run the mimimized testcase folder using mozmill-restart

Alex, can you please bisect the regression range so we know which patch caused this problem? Thanks!

Started building today.

Finished bisecting. The first bad revision is https://hg.mozilla.org/mozilla-central/rev/c122628565e5

I filed bug 813699 today because I was seeing a lot of release update testrun hanging for an hour before aborting themselves. Speaking with Dave Hunt on IRC, he suspects *this* bug might be related.

The first bad revision is > https://hg.mozilla.org/mozilla-central/rev/c122628565e5 Thanks for finding the regression range but why is this bug now waiting for my response? Get a regression bug filed for Firefox so that devs are aware of that problem and it can be fixed.

Wasn't sure of what the next step was, but now it's clear. Filed bug 814430

This was fixed by bug 814430. Closing as RESOLVED FIXED
