1047960 - burst of 8 ASSERTION: Received "nonqueued" message 494?? during a synchronous IPC message for window ?????? on varying reftests

Status: RESOLVED WORKSFORME

(Core :: Widget: Win32, defect)

Description

[David Baron :dbaron: (⌚️UTC-4, no longer working on Mozilla)]

Seems likely to be a regression from bug 1039666 similar to bug 1047842, but jesup suggsted I file I separate bug.

We've seen some bursts of assertions in varying reftests today.  Two on the same push just now (the original run and its retrigger to see if the failure was random):

(#developers)
[2014-08-02 20:32:00 -0700] <dbaron> jesup, there are intermittent "nonqueued" assertions on random reftests
[2014-08-02 20:32:13 -0700] <dbaron> jesup, like https://bugzilla.mozilla.org/show_bug.cgi?id=1047842
[2014-08-02 20:32:16 -0700] <dbaron> jesup, showing up in clumps of 8
[2014-08-02 20:32:37 -0700] <dbaron> jesup, see, e.g., Windows XP Debug reftest in https://tbpl.mozilla.org/?tree=Mozilla-Inbound&rev=2bdb11379d0f
[2014-08-02 20:32:47 -0700] <dbaron> jesup, should those get starred as 1047842 or as a new bug?
[2014-08-02 20:32:58 -0700] <dbaron> jesup, presumably a regression from 1039666?
[2014-08-03 00:05:39 -0700] <jesup> dbaron: ping
[2014-08-03 00:05:45 -0700] <dbaron> jesup, pong
[2014-08-03 00:08:21 -0700] <jesup> dbaron: I'd say new bug: different message type, not in a window/screensharing test - and those were on XP, and window/screensharing is turned off for XP and the tests aren't run.   Those *are* the assertions we see in bug 1044245 (even after jimm's patch to stop the other assertions)
[2014-08-03 00:09:57 -0700] <jesup> And in those tests, I see them in bursts of ~8.  Is the reftest testing GMP or any of cpearce's new GMP/EME stuff?  (like the patch the push you linked was from)
[2014-08-03 00:10:44 -0700] <jesup> well, they're close 49452 vs 49456, so maybe different.  Ask jimm
[2014-08-03 00:11:07 -0700] <jesup> perhaps file a bug and cc/needinfo him

also see bug 1027927

Comment 2

[Phil Ringnalda (:philor)]

Not to mention several other things which are probably also duplicates of bug 874437.

Comment 3

[Jim Mathies [:jimm]]

These are all RegisterWindowsMessage values. They could be our registered messages, or more likely they are internal messages Windows generates. The side effects of not delivering these are unknown.

Comment 4

[Jim Mathies [:jimm]]

new signature:

[14384] ###!!! ASSERTION: Received "nonqueued" registered windows message (0xCXXX) during a synchronous IPC message for window 0xXXXXX ("SomeWindow"), sending it to DefWindowProc instead of the normal window procedure.
