Representative example in http://tinderbox.mozilla.org/showlog.cgi?log=Firefox/1307400826.1307404228.31543.gz&fulltext=1#err0 - at some point in e4x/Regress/regress-373082.js (not the same point in all runs), it apparently drifts off to sleep, there's a section of httpd.js GC (which started filling up the Android logs with bug 508128), then a 2400 seconds without output timeout. So far since the merge, there have been 3 instances of this, 2 of an unrelated infra failure, and one passing run.

Starting to think that regress-373082.js is just the most common, or maybe it's very long so it offers more opportunity to be the one running when it hits. These two are in ecma/Date/15.9.5.9.js and ecma/Expressions/11.7.1.js. http://tinderbox.mozilla.org/showlog.cgi?log=Firefox/1307722194.1307727575.18058.gz&fulltext=1 http://tinderbox.mozilla.org/showlog.cgi?log=Firefox/1307698665.1307702713.28087.gz&fulltext=1

What's up with all the before ... after ... messages? Aren't they from gc ? Is there a stuck preference somewhere ?
They're from httpd.js doing gc, since bug 508128. I'm hoping that it's not a problem, other than being massively annoying in Android logs (particularly when it shows up in the middle of data: URIs in reftest logs).
I'm wondering if the successful deletion of Object.prototype.toString would cause reftest to stop responding? Would saving toString prior to the deletion and restoring it after the assigment to actual help? expect = 'TypeError: String.prototype.toString called on incompatible XML'; try { delete XML.prototype.function::toString; > var saveToString = Object.prototype.toString; delete Object.prototype.toString; actual = <a>TEXT</a>.toString(); > Object.prototype.toString = saveToString } catch(ex) { actual = ex + ''; } TEST(7, expect, actual);
http://tinderbox.mozilla.org/showlog.cgi?log=Mozilla-Inbound/1307764851.1307769546.24158.gz&fulltext=1 We've apparently pretty much thoroughly broken it, I'm hiding it on mozilla-inbound.
Igor, ping comment 15 ?

lets try this.

Comment on attachment 540104 [details] [diff] [review] patch I think that code's supposed to throw, so putting that in a finally block would be better, if the patch actually does anything to address this.
Thanks Waldo. I'll try it on try.

try doesn't run jsreftests on android yet. philor is going to hide this until we get that resolved.

So lets write this as: delete XML.prototype.function::toString; var xml = <a>TEXT</a>; var saveToString = Object.prototype.toString; delete Object.prototype.toString; try { actual = xml.toString(); } catch(ex) { actual = ex + ''; } finally { Object.prototype.toString = saveToString; } Note that the try covers only the part of the code that is expected to throw.

Has this patch landed in m-c yet? I ask because I see later reports of continues problems, but cant tell if this fix landed yet or not.
(In reply to comment #100) > Has this patch landed in m-c yet? I ask because I see later reports of > continues problems, but cant tell if this fix landed yet or not. No, but the problem still persists on tracemonkey where it did land.
cdleary-bot mozilla-central merge info: http://hg.mozilla.org/mozilla-central/rev/2ff6092157a5 Note: not marking as fixed because fixed-in-tracemonkey is not present on the whiteboard.
Depends on: 668594
Is this still happening, or did bug 668594 fix it?
that bug landed on 07-09 (4 days ago) on mozilla-central. I would say this is fixed, and if we see issues we can reopen. If y'all agree, change the status.
