Reported 2006-07-08 20:51:03 PDT
Every now and then I get a crash when reloading the webkit-unassigned month-by-date web page (see URL above).  Most of the time I've noticed it happens after I've reloaded the page, then hid Safari or switched to another application.  The following stack trace occurred with Mac OS X 10.4.7 (8J135/PowerPC) with Safari 2.0.4 (419.3) and a locally-built WebKit r15239 (with local patches for Bug 9179). I think Darin might have mentioned a similar problem today in another bug comment, but I'm not sure I could find it now.

Created attachment 9366 [details] Another crash from 2006-07-11 I'm hating myself for not putting the other crash logs in attachments now, so here is another example of the same crash as an attachment. This time, though, I modified line 1118 in WebHTMLView.m from this: 1118: NSRect visibleRect = [[[[lastHitView _frame] frameView] _scrollView] documentVisibleRect]; To this: 1118: WebFrame* frame = [lastHitView _frame]; 1119: WebFrameView* frameView = [frame frameView]; 1120: NSScrollView* scrollView = [frameView _scrollView]; 1121: NSRect visibleRect = [scrollView documentVisibleRect]; The crash log still notes line 1118, which means it's failing on the first call.  I don't have any idea what "objc_msgSend_rtp" means, though.  Looks like a Very Bad Thing(tm) is happening with an internal ObjC method.

(In reply to comment #4) > I don't have any idea what "objc_msgSend_rtp" means, though.  Looks like > a Very Bad Thing(tm) is happening with an internal ObjC method. Doing some Google research, this points to an object either being over-released: http://www.cocoabuilder.com/archive/message/cocoa/2005/6/10/138462 Or being under-retained: http://www.cocoabuilder.com/archive/message/cocoa/2005/12/24/153164 I'm not sure if this helps or not.  I guess I should review where _frame is being retained and released to find out.  (This only happens on reloads, so it may be some kind of race condition.)  Should I run WebKit+Safari with MallocScribble on until it crashes again? Since I'm seeing this bug intermittently (although I can't reproduce it on demand), I'm marking this as a regression and a P1 with the NeedsRadar keyword.

It most likely means that lastHitView points to a deallocated object. Enabling zombies might help with debugging this crash. See http://developer.apple.com/technotes/tn2004/tn2124.html#SECFOUNDATION

Sometimes I start getting these in the console, one per movement of the mouse over the affected window: 2006-07-12 10:21:44.714 Safari[4187] Exception raised during posting of notification.  Ignored.  exception: *** -[NSToolbarItemViewer _frame]: selector not recognized [self = 0x19b580b0] 2006-07-12 10:21:44.731 Safari[4187] *** -[NSToolbarItemViewer _frame]: selector not recognized [self = 0x19b580b0] Again, looks like the lastHitView has been released and a different object (NSToolbarItemViewer) has taken its place.

This crash can happen after those situations where -[WebHTMLView close] is called a second time. The second time it's called (from -dealloc), it returns immediately, but by that time, things that -close cleans up could have gotten dirty again. Before r15106, the cleanup was done unconditionally in -dealloc. The real solution is to make sure no "dirtying" takes place when _private->closed is true. A quick hackish fix is to change -close to do its thing unconditionally.

Comment on attachment 9402 [details] Possible fix (with logging) David Kilzer and I applied the patch locally, and so far both of us have gotten the "_private->closed" condition logged multiple times, but the crash doesn't happen (nor bug 9850 or the "selector not recognized" exceptions).

And one action in Safari (like a "Back" button hit or a page reload) generates tens (if not over 100) log messages to the console.

Created attachment 9815 [details] Crash log from locally-built debug build of r15751 In this crash, I had right-clicked on a tab and selected "Reload All Tabs". There were four tabs in the set that were originally opened via "Open in Tabs" from the Bookmarks menu. The first URL is a saved Bugzilla search, so I will post the actual search rather than the saved one (since no one else will be able to access it). 1. http://bugzilla.opendarwin.org/buglist.cgi?query_format=advanced&short_desc_type=allwordssubstr&short_desc=&product=WebKit&component=Accessibility&component=CSS&component=Drosera&component=Evangelism&component=Forms&component=Frames&component=History&component=HTML+DOM&component=HTML+Editing&component=Images&component=Java&component=JavaScriptCore&component=JavaScriptGlue&component=Layout+and+Rendering&component=New+Bugs&component=Page+Loading&component=PDF&component=Platform&component=Plug-ins&component=Printing&component=Reindeer&component=SVG&component=Tables&component=Text&component=Tools&component=Web+Inspector&component=Web+Template+Framework&component=WebCore+JavaScript&component=WebCore+Misc.&component=WebKit+API&component=WebKit+Misc.&component=WebKit+Website&component=XML&component=XML+DOM&version=312.x&version=412&version=412.x&version=416.x&version=417.x&version=418.x&version=419.x&version=420%2B+%28nightly%29&long_desc_type=substring&long_desc=&bug_file_loc_type=allwordssubstr&bug_file_loc=&keywords_type=allwords&keywords=&emailassigned_to1=1&emailtype1=substring&email1=&emailassigned_to2=1&emailreporter2=1&emailcc2=1&emailtype2=substring&email2=&bugidtype=include&bug_id=&votes=&chfieldfrom=&chfieldto=Now&chfieldvalue=&cmdtype=doit&order=Reuse+same+sort+as+last+time&query_based_on=WebKit+Daily+Changes&field0-0-0=%28TO_DAYS%28NOW%28%29%29+-+TO_DAYS%28bugs.delta_ts%29%29&type0-0-0=lessthan&value0-0-0=1 2. http://build.webkit.org/ 3. http://cia.navi.cx/stats/project/webkit 4. http://www.opendarwin.org/pipermail/webkit-unassigned/2006-August/date.html This was not the first time I had reloaded the tab set. After selecting "Reload All Tabs" from the contextual menu, I did use Cmd-Tab to switch to another application (probably Mail.app). The crash either started just before or just after I switched since I noticed a CPU spike, then Activity Monitor's process list had "crashreport..." listed in it.

Comment 21 2006-08-02 04:26:48 PDT
I think now that the only short term fix is to close unconditionally (or just set _private->closed to NO prior to calling [self close]).
Timothy Hatcher
Comment 22 2006-08-02 08:58:11 PDT
In [WebHTMLView close] I think we need to call: [NSObject cancelPreviousPerformRequestsWithTarget:self selector:@selector(_updateMouseoverWithFakeEvent) object:nil]; Since _updateMouseoverWithFakeEvent is being fired from __NSFireDelayedPerform.
Timothy Hatcher
Comment 23 2006-08-02 08:59:42 PDT
We should cancel other delayed selector calls too. _updateActiveState and _delayedEndPrintMode:
Darin Adler
Comment 24 2006-08-02 09:30:17 PDT
Tim's comments are definitely pointers in the right direction. We need to stop any timers. We also need to make sure that code (JavaScript, etc.) running in other WebView instances will not find this frame even after it's closed.
