17948 2008-03-19 07:06:16 -0700 Exception in -[WebDataSource webArchive] 2008-11-25 13:47:30 -0800 1 1 1 Unclassified WebKit WebKit API 523.x (Safari 3) Mac OS X 10.5 RESOLVED FIXED P2 Normal --- 0 mjt webkit-unassigned beidson ddkilzer oldest_to_newest 74432 0 mjt 2008-03-19 07:06:16 -0700 I've seen several cases where WebKit raises an exception: -[NSCFArray insertObject:atIndex:]: attempt to insert nil when my code calls [[[webView mainFrame] dataSource] webArchive]. I've been able to reproduce this only rarely on my Mac, but I have a customer for whom it happens 100% of the time, no matter the page. As far as I can tell, the exception is being raised in -[WebDataSource subresources]. It looks like the WebResource that's being created in the loop is returning nil from its -init method. While there may be an interesting and significant reason for that, I suggest that -subresources refrain from adding nil objects to the array so that at least a partial Web archive can be returned. 100038 1 ddkilzer 2008-11-24 13:28:18 -0800 Does your customer have any third-party "extensions" (haxies, input managers, etc.) installed for Safari? 100049 2 mjt 2008-11-24 13:41:11 -0800 No. 100140 3 ddkilzer 2008-11-24 20:15:58 -0800 Could you have the customer recreate the crash and post a crash log to this bug? If you would prefer not to post a crash log of your application here, please create a bug using <https://bugreport.apple.com/> and report the 7-digit bug number here. 100205 4 mjt 2008-11-25 06:19:35 -0800 It's not crashing for the customer, just raising an exception that's caught in my code. 100228 5 ddkilzer 2008-11-25 10:16:58 -0800 (In reply to comment #4) > It's not crashing for the customer, just raising an exception that's caught in > my code. Is there any way you could provide a stack trace when the exception is caught? Can you provide a reproducible test case using a local copy of the customer's web page? BTW, what revision(s) of WebKit are you using? Does this work on a nightly WebKit build? After re-reading the description, this sounds related to Bug 22466. I think the code in WebKit -[WebDataSource subresources] has moved to DocumentLoader::subresources() in tip-of-tree (ToT) WebKit, though. 100242 6 mjt 2008-11-25 11:16:14 -0800 One of the problem Web pages was: http://www.faqts.com/knowledge_base/index.phtml/fid/199/ I am no longer able to reproduce the problem using the WebKit from Safari 3.2.1. 100244 7 ddkilzer 2008-11-25 11:26:46 -0800 (In reply to comment #6) > One of the problem Web pages was: > > http://www.faqts.com/knowledge_base/index.phtml/fid/199/ > > I am no longer able to reproduce the problem using the WebKit from Safari > 3.2.1.
