Crashes while scrolling [@ ns
Scroll Port View::Incremental Scroll()]
User-Agent: Mozilla/5.0 (Macintosh; U; PPC Mac OS X 10.4; en-US; rv:18.104.22.168) Gecko/2008070206 Firefox/3.0.1 Build Identifier: Mozilla/5.0 (Macintosh; U; PPC Mac OS X 10.4; en-US; rv:22.214.171.124) Gecko/2008070206 Firefox/3.0.1 Yesterday set preferences to "Use smooth scrolling" (unchecked "Use Autoscrolling). Today multiple crashes while attempting to scroll. Seems much worse when attempting to scroll while page is loading/reloading, but sometimes happens even when page is loaded. Reset to "Use Autoscrolling"; now seems stable again. Reproducible: Sometimes Steps to Reproduce: 1.See above. 2. 3. Actual Results: See above. If I can help with any testing or provide additional info, please advise.
Daniel: I am not able to reproduce this using Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.5; en-US; rv:126.96.36.199) Gecko/2008070206 Firefox/3.0.1 or with the 3.0.2 candidate. Which particular site were you scrolling? Can you type about:crashes and provide a crash URL?
I was not able to reproduce on a PPC machine either using 3.0.1.
Hi Marcia- Yes, I was able to reproduce the problem by (as before) changing the Firefox scrolling preferences to "Use smooth scrolling" and unchecking "Use Autoscrolling". Again, the problem seems to be associated with attempting to scroll while a page is loading or reloading. The URL that I tested this time was: http://www.newsweek.com/id/158429?from=rss The URL info after "www.newsweek.com/" is specific to a particular Newsweek article... The previous crashes occurred at the same Newsweek URL but with different specific articles. To obtain more of a sampling, I also just tried a Washington Post newsarticle: http://www.washingtonpost.com/wp-dyn/content/article/2008/09/07/AR2008090702262.html?nav=rss_world and I was able to crash at that site also. Finally, I tried the same thing while reloading https://bugzilla.mozilla.org/show_bug.cgi?id=454872, but was not able to crash the browser.
Daniel, please submit the crash data and then give us its ID. You can see the IDs if you enter about:crashes in the url bar. See: http://support.mozilla.com/en-US/kb/Mozilla+Crash+Reporter#Viewing_crash_reports

Thanks for trying to figure this out! db
For what it may be worth, here are all of the similar reports that I was able to find: 263609 (Windows) 385100 (Windows) 433365 (Mac)
Possibly fixed in Firefox 3.0.2 by bug 435422. You can try with the release candidates here (which includes the fix): http://ftp.mozilla.org/pub/mozilla.org/firefox/nightly/3.0.2-candidates/ or you can wait until it's officially released (currently planned for Tuesday 16th but it might be later).

Thanks for the info. Since it doesn't crash unless I change the scrolling preferences it's not a big deal. I think that I'll wait for the official rollout.
FYI, Firefox 3.0.2 is available now.
Mats- thanks a lot for keeping on top of this. I'll let you know how things work out after I download 3.0.2
Looks like you folks have nailed it. 3.0.2 seems to work just fine as far as the scrolling preferences are concerned. Thanks to all.
Ok, good to hear it's working for you. I'll leave the bug open for now since I can't query crash statistics at the moment (bug 444749) and I want to verify it's really gone in 3.0.2.

There are still some crash reports for 3.0.2 and 3.0.3 I'm afraid.
There were 72 crashes in the last week at nsScrollPortView::IncrementalScroll. All OSes are represented, but Mac is especially heavy. Both active releases of Firefox, 3.0.x and 3.5.x, are represented. http://crash-stats.mozilla.com/report/list?product=Firefox&query_search=signature&query_type=startswith&query=nsScrollPortView%3A%3AIncrementalScroll%28%29&date=&range_value=1&range_unit=weeks&do_query=1&signature=nsScrollPortView%3A%3AIncrementalScroll%28%29
Looking at the code I'm guessing the nsScrollPortView is dead by the time we execute line 726: http://hg.mozilla.org/releases/mozilla-1.9.1/annotate/345e7a83db64/view/src/nsScrollPortView.cpp#l726 Assuming nsScrollPortView::ScrollToImpl() can execute arbitrary stuff like deleting the 'this' nsScrollPortView we're currently using.
OS: Mac OS X → All
Hardware: PowerPC → All
Should fix it if my assumption is right.
Attachment #395330 - Flags: review?(mstange)
nsScrollPortView::ScrollToImpl calls nsScrollPortView::Scroll calls nearestWidget->Scroll There's an analysis of widget methods that reach nsChildView::DispatchEvent (which executes arbitrary stuff) in bug 402505. nsChildView::Scroll is in that list. Seems like a good idea to audit nsScrollPortView for calls reaching anything on that list.
... although the list could be out-dated by now of course ...
The patch looks good to me, but I'm not a peer of this code.
Sorry, I assumed you were...

Comment on attachment 395330 [details] [diff] [review] Patch rev. 1 As a security bug, per our new policy, this patch needs explicit superview from a second person. It should *not* have landed on trunk or 1.9.2 without that superview. Please be mindful of that in the future. http://www.mozilla.org/hacking/reviewers.html Tagging dbaron for superview.

That's a bad policy, as I've said before.
There are many bad policies, but it *is* a policy and we'll keep enforcing it until it's no longer a policy.
(In reply to comment #28) Sorry I missed that!
