433646 - "ASSERTION: Cannot process pending updates with refresh disabled" with xul:iframe, MathML

Status: RESOLVED WORKSFORME

(Core :: MathML, defect)

Description

[Jesse Ruderman]

Attachment: testcase

If I load the testcase as a local file, I usually see the assertion within a minute.

###!!! ASSERTION: Cannot process pending updates with refresh disabled: 'mRefreshEnabled', file /Users/jruderman/trunk/mozilla/view/src/nsViewManager.cpp, line 641

Gary Kwong and I have been hitting this assertion occasionally for a while, but Gary finally managed to make a reasonably simple testcase that triggers it reliably.  I helped reduce it further, making it a bit less reliable, but hopefully still reliable enough.

I believe roc is hoping this will go away when he implements Compositor (bug 374980).

Attachment: faster testcase

To increase speed and make automated testing easier, I made it start over instead of reloading.

Comment 2

[Jesse Ruderman]

Still happens on trunk.  Testcase must be loaded locally.

Comment 3

[:Cykesiopka]

In Bug 545593, the assert was changed to:
  NS_ASSERTION(IsRefreshEnabled(), "Cannot process pending updates with refresh disabled");

Which was in turn removed as part of Bug 598482.
