Details

Just hit a sporadic crashtest leak on tryserver, in an otherwise-entirely-green push. Pretty certain it wasn't related to the patch I was testing (which I then pushed to m-c).

Rev3 Fedora 12 try debug test crashtest on 2011/05/06 09:54:15

s: talos-r3-fed-034
TEST-UNEXPECTED-FAIL | automationutils.processLeakLog() | leaked 13203179 bytes during test execution
TEST-UNEXPECTED-FAIL | automationutils.processLeakLog() | leaked 133 instances of AtomImpl with size 20 bytes each (2660 bytes total)
TEST-UNEXPECTED-FAIL | automationutils.processLeakLog() | leaked 1 instance of BackstagePass with size 24 bytes
TEST-UNEXPECTED-FAIL | automationutils.processLeakLog() | leaked 2 instances of CommonAnimationManager with size 28 bytes each (56 bytes total)
TEST-UNEXPECTED-FAIL | automationutils.processLeakLog() | leaked 1 instance of DR_State with size 40 bytes
TEST-UNEXPECTED-FAIL | automationutils.processLeakLog() | leaked 1 instance of DocumentRule with size 36 bytes

I'm guessing this might have to do with CSS animations, given that 2 CommonAnimationManager objects were leaked.

Mass marking whiteboard:[orange] bugs WFM (to clean up TBPL bug suggestions) that:
* Haven't changed in > 6months
* Whose whiteboard contains none of the strings: {disabled,marked,random,fuzzy,todo,fails,failing,annotated,leave open,time-bomb}
* Passed a (quick) manual inspection of bug summary/whiteboard to ensure they weren't a false positive.

I've also gone through and searched for cases where the whiteboard wasn't labelled correctly after test disabling, by using attachment description & basic comment searches. However if the test for which this bug was about has in fact been disabled/annotated/..., please accept my apologies & reopen/mark the whiteboard appropriately so this doesn't get re-closed in the future (and please ping me via IRC or email so I can try to tweak the saved searches to avoid more edge cases).
