24027 2009-02-19 10:15:16 -0800 Do not send loader callbacks during CSS styling 2009-04-24 12:35:27 -0700 1 1 1 Unclassified WebKit Page Loading 528+ (Nightly build) All All RESOLVED FIXED P2 Normal --- 1 zwarich mitz ddkilzer koivisto oldest_to_newest 110224 0 zwarich 2009-02-19 10:15:16 -0800 Currently loader callbacks are sent during CSS styling, e.g. if a CSS background image is loaded from the cache. Since styling is not reentrant and loader callbacks may provoke CSS styling from the WebKit client, this is not safe. The fix is to delay sending the callbacks until styling has completed. See the discussion in bug 22521 for more details. This caused crashes with iChat, which were fixed by Mitz with a workaround in r41071. I assigned this bug to him because he has the best idea of how to make the correct fix. 110233 1 27798 mitz 2009-02-19 11:02:30 -0800 Created attachment 27798 Suspend memory client callbacks during
