Some are still claiming that <a href="http://www.appleinsider.com/articles/08/11/06/microsofts_ballmer_considers_using_webkit_within_ie.html" target="_blank">Microsoft will go with WebKit</a>, which, thanks to the popularity of Apple's Safari browser and also Google's Chrome, is rapidly becoming a de facto standard for all non-IE and non-Firefox implementations.</p> <p>Others insist that that the whole WebKit story is merely a feint and that Microsoft will in fact be adopting a <a href="http://www.jcxp.net/news.php?newsid=2650" target="_blank">brand-new engine</a> coming out of its Microsoft Research division. Dubbed <a href="http://weblog.infoworld.com/fatalexception/archives/2009/02/gazelle_the_bro.html">"Gazelle,"</a> this new engine will supposedly be more secure than Firefox or even Chrome, making copious use of sandboxing to keep its myriad plug-ins isolated and the overall browser process model protected.</p> <p><b>[ Get the <a href="http://weblog.infoworld.com/fatalexception/archives/2009/02/gazelle_the_bro.html?source=fssr">full scoop on the Gazelle browser technology</a> that may replace Internet Explorer. ]</b></p> <p>But regardless of which direction Microsoft takes -- WebKit or Gazelle -- it will still have to navigate the treacherous waters of legacy ActiveX support. And as someone who has spent some not-so-quality time developing ActiveX controls in the past, the need to maintain some sort of compatibility layer within any proposed IE replacement is a critical consideration.</p> <p>For most casual users (i.e., grandma in her den surfing eBay), ActiveX was and is just another annoying <a href="http://www.infoworld.com/article/09/01/02/53TC-ria-rollup_1.html">RIA (rich Internet application) mechanism</a>, one that has increasingly been supplanted by Adobe Flash or various AJAX-based mechanisms. However, for enterprise IT shops with a heavy Microsoft investment, ActiveX has long been an integral part of many in-house applications. </p> <p>If Microsoft intends to pull the plug on IE after version 8, it will need to articulate a clear legacy migration strategy that allows these shops to preserve their investments in ActiveX controls and resources.</p> <p>Then there’s the issue of legacy HTML/CSS support. So much of the Web has been tweaked for IE 6.x compatibility that even Microsoft's own attempts to implement a more standards-compliant browser engine in IE8 have met with disastrous results. For me, the situation so bad that when I do find myself using IE 8 (typically, to view a site that causes my copy of the Chrome 2.x beta release to blow up), I end up configuring IE 8's compatibility mode as the default viewing option since the browser's native rendering mode breaks practically every site I visit.</p> <p>Finally, there's the matter of third-party developers using IE's rendering engine with their own applications. A good example would be a program that includes a help file in HTML format and then uses a custom form to display an embedded Web browser object to host the file. This embedded object is invariably an ActiveX container for the IE engine that's installed with Windows, so any attempt to remove IE from the OS -- or to radically change its core underpinnings -- will need to account for applications that rely on the existence of an accessible, programmable IE object model.</p> <p>Of course, all of the above is old hat for Microsoft, a company whose status as global software leader too often makes it a victim of its own success. I, for one, look forward to the possibility of a clean break with IE's creaky old rendering engine. But I hope the company pays more care and attention to preserving legacy compatibility than it did with some of its more recent OS efforts.</p> <a name="more"></a> <p>Posted by Randall C.

Don't paste giant blobs like this into bugs. Attach them, if need be. (and you didn't need to do anything but link to it, in this case) Also, crashes are never minor; crashes are all critical. I see no problems. (tested with 3.0.7 on WinXP/Linux & 3.1b4pre on Linux) Please post your crash ID: https://developer.mozilla.org/en/How_to_get_a_stacktrace_for_a_bug_report

I can reproduce it reliably: bp-a9c6b9b7-d67a-4146-8ace-ad4322090310 If it doesn't happen at once, try clearing cookies and reload, the crash seems to be caused by a popup window that only opens occasionally. Maybe dupe of bug 469366?

Making a testcase by reducing the content from the URL looks hard. I grabbed the content involved and it has 14000 lines of JS, I looked briefly at some of it and it's hairy... I think what happens is that during page load a new window (a survey) is opened (in the absence of a cookie), while this happens the main window content is replaced with an ad that has a timer, after a few seconds the normal main window content is presented again. It looks like the crash occurs when the main window transitions from normal content to ad content. I can't reproduce the crash in current Firefox trunk or 1.9.1 builds (on Linux i686), nor in a trunk debug build (Linux x86_64). What's more surprising is that I can't reproduce the crash in a 1.9.0 Firefox debug build (Linux x86_64), but nightly builds (i686) crashes reliably. I think that's because the bug is timing dependent rather than being 32-bit only. All of the above with the same profile, which has Firebug installed and enabled. If I disable Firebug in this profile I can't reproduce the crash. I can't reproduce the crash in a clean profile either (after allowing the popup window to open). Bug 469366 also mentions Firebug... again, this could be that Firebug affects the timing somehow rather then being the direct culprit. So, the profile requirements for crashing: Firebug + allow popup windows. BTW, I see the following assertions in all debug builds tested above (also on trunk) when the popup window opens: ###!!! ASSERTION: Already have an undisplayed context entry for aContent: '!GetUndisplayedContent(aContent)', file layout/base/nsFrameManager.cpp, line 588 ###!!! ASSERTION: Shouldn't happen: 'aPresContext->GetPresShell()->GetPrimaryFrameFor(mContent) == this', file layout/generic/nsFrameFrame.cpp, line 501 ###!!! ASSERTION: Already have an undisplayed context entry for aContent: '!GetUndisplayedContent(aContent)', file layout/base/nsFrameManager.cpp, line 588 the middle one in nsFrameFrame.cpp could be related...

Actually, the reason trunk/1.9.1 doesn't crash could be that Firebug was automatically disabled since it's "incompatible"... I'll try with Firebug 1.4 alpha...

[Calcification on Firefox 3.07 take down] This occurred when a link in a email newsletter from InfoWorld Daily was opened in Gmail. When opening the below link in Gmail, a new tab is opened when first link link is opened: Is IE8 the end of the line for Internet Explorer? http://ifwnewsletters.newsletters.infoworld.com/t/4523793/121893644/174360/0/ Then redirects to: http://weblog.infoworld.com/enterprisedesktop/archives/2009/03/is_version_8_th.html?source=NLC-DAILY&cgd=2009-03-10 It seems that when the direct happens your are shown a advertisement page first before you are brought to the second link. I tried this using Internet Explorer and was shown the advertisement before the main page was loaded. I just tried opening the first link in in Gmail and once again Firefox 3.07 was taken down. I believe that the actual advertisement page or pop up ad may have some malice code which is what took down the browser. I looked at the email newsletter source code and didn't find anything that looked out of the normal I tried looking at the source code of the advertisement page but couldn't because after a certain amount of time (less then a minute), your are redirected to the second link. Kind of odd that the news story is about Explorer 8 and it takes down Firefox?

firebug-1.4.0a12.xpi does not work in Firefox 1.9.1 or trunk, so it's still unknown if the crash would occur there... the error is: JavaScript error: chrome://browser/content/browser.xul, line 1: Firebug is null

John, if you can try Firefox 3.1b4pre that would help us: http://ftp.mozilla.org/pub/mozilla.org/firefox/nightly/latest-mozilla-1.9.1/firefox-3.1b4pre.en-US.win32.zip just unzip it into an empty directory and start it from there. If you do then please list the add-ons again -- some of them might have been disabled for compatibility reasons when running in 3.1b4.

... or if can run with Firefox 3.0.7 and disable your add-ons one by one and then restart Firefox and try to crash it, that would help to determine which add-on is causing the crash in your case. I'll try to install the add-ons you have too...

The add-on "Header Spy 1.3.3" is sufficient to trigger the crash in 1.9.0, it's incompatible with 1.9.1 and trunk though.

Finally got it to crash in a debug build, 1.9.0 on MacOSX with Firebug 1.3.3. There's an additional assertion (to the ones in comment 4): ###!!! ASSERTION: What's going on?: 'mInnerView', nsFrameFrame.cpp, line 855

I installed Firefox build # "3.1b4pre" and tried about 10 times and could not crash the browser. I even tried deleting the cookies and the crash didn't occur. I did not install any extensions, and Fire-Bug can't be installed on that version which was already stated here. Disabling each extension and retrying to recreate the crash will take some time. Might try do this on Monday 03/16. john@antihotmail.com

The bug also occur on trunk. It's the content sink that notifies content that has already been notified on, leading to nsCSSFrameConstructor::ContentAppended for content that already has a frame in the frame tree. It seems that trunk is quite resilient to this and doesn't crash (never?), but 1.9.0 crashes reliably when the content node is an <iframe> (as in the STR in this bug). On trunk, the problem occurs for example when running (all) mochitests under content/base/ -- it leads to double frame creation for the <div> in test_bug338679.html, but loading this test directly doesn't trigger it. (do we have bugs open on "content doubling"?) The attached trace is from such a mochitest run on trunk. The first content and frame dump is from the shell InitialReflow. After that the sink is what I call "clean" (mNumFlushed == childCount on all stack levels, ie. FlushTags() wouldn't notify anything if called). Then we run some script, leading to ContentRemoved/Appended/Inserted... at some point the child count grows beyond what the sink's mNumFlushed (I log this as "dirty"). The problem seems to be that we never reach any UpdateChildCounts()... I'm guessing this should occur in nsContentSink::EndUpdate on the outermost level? http://mxr.mozilla.org/mozilla-central/source/content/base/src/nsContentSink.cpp#1674 but we reach FlushTags() before that, which notifies... see the stack at the end.

For the record I noted that in nsContentSink::ContinueInterruptedParsingAsync() we don't check if there is a pending event... http://mxr.mozilla.org/mozilla-central/source/content/base/src/nsContentSink.cpp#1760 ... (because there are consecutive WillInterrupt() calls without a WillResume() call) not sure how much a problem that is... fixing it did not help with notification problem described above.

Perhaps a regression from bug 448564 could be causing this to be a new topcrash on branch, since that landed there not too long ago and was also about double-notifying in the content sink. Actually, looking closer, one of the assertion in comment 4 here is also in comment 1 of that bug in the same function we're crashing in.

If not on page load, then on page unload. > it leads to double frame creation for the <div> in test_bug338679.html Right. That makes sense given your stacks. That said, is that what the original page was seeing? Your debug log is pretty specific to having a mutation listener that modifies the DOM (and I was sure we had a bug on this already, fwiw... I certainly remember talking to sicking about this), and I doubt that the site this was filed on is doing that. > I'm guessing this should occur in nsContentSink::EndUpdate on the outermost > level? I think we should be updating child counts from all updates started from inside a mutation listener. Perhaps what we should really be doing is UpdateChildCounts any time we get an EndUpdate and there are no script blockers about? Except of course EndUpdate happens before we remove script blockers, on trunk...

When Better Privacy Extension 1.24 is disabled using Firefox 3.07 the browser does not crash. :--) Ten attempts to create crash with above extension disabled.

(In reply to comment #25) > Perhaps a regression from bug 448564 could be causing this... That bug touches the relevant code, but didn't directly cause the regression AFAICT. For the STR in comment 17 with Firefox 3.0.7pre MacOSX and Linux i686 nightly builds, I get the regression range 2009-02-03-04 -- 2009-02-04-04: http://hg.mozilla.org/mozilla-central/pushloghtml?startdate=2009-02-03+00%3A00&enddate=2009-02-04+05%3A00 None of the checkins in that range looks suspicious to me though, so maybe a combination of bug 448564 and something in this range? (Linux builds are less crashy at the Infoworld URL today, so no reliable range there yet, only data point so far is that 2009022204 crashes).

(In reply to comment #26) > That said, is that what the original page was seeing? Yes, the STR in comment 17 leads to FC::ContentAppended with an existing frame too, on both trunk and 1.9.0, with the same stack, but this stack is different from the one in attachment 367928 [details] (for the mochitest run). For the mochitest stack, it looks like the problem is at this point: #51 0x120f6ccb in nsEventDispatcher::Dispatch #52 0x120548f7 in nsGenericElement::SetAttrAndNotify Dispatch() is called in the same scope as the mozAutoDocUpdate: http://mxr.mozilla.org/mozilla-central/source/content/base/src/nsGenericElement.cpp#4284 which is the cause for the "missing" UpdateChildCounts(). Adding a scope around the first part of the method so that firing the mutation event is outside seems to fix that problem... I can now run a full mochitest run without any existing frames in FC::ContentAppended.

Hmm. We aren't in an update in that last stack, are we? At least not that I can see... As for mutation events, they generally fire inside updates as I recall. That patch fixes the attr modification case, but the ones for content insertion, etc, fire inside updates too...

This has been getting a lot of reports on SUMO -- any news? Looks kinda dead in here. Should we unhide the bug so the people who were adding their stacks/info to bug 469366 can add them here?
|
|
||
Comment 35•15 years ago
|
||
So maybe the right thing to do is: 1) When removing removable script blockers, set a flag. 2) If a mutation happens in a document while the flag is set, add the document to a list. 3) When restoring removable script blockers, update child counts on content sinks for all documents in the list. Jonas, Olli, what do you think of that approach?

I think so; that stack was to the point where we create the frame the second time; the goal is to have child counts updated sometime before that.

A user on SUMO live chat was able to reproduce this by: 1. Go to http://www.cars.com 2. Search for a used Ford Fusion in zip code 46032 3. Click on a specific car to view details 4. Press the Back button 5. Repeat steps 3-4 several times, going between cars These steps were able to crash Firefox with this stack during the chat session.

Comment on attachment 385101 [details] [diff] [review] possible patch Boris, Jonas, any comments to this. Allow sink (but not layout) to be flushed, even though there are script blockers. This brings back the old behavior. Other option would be to postpone iframe initialization, but that might be a bit more riskier change.

Hmm. So looking at that last stack, that just shows where we end up flushing during scriptblocker, right? And the key is that we're flushing content on the subframe and need to get that right per the document viewer comments, but there is a script blocker in the parent document, right? It does seem like the right way to do this is to move the ShowDocShell() off on a script runner, but I can understand not wanting to do this for 1.9.0 or 1.9.1 at this point.... I assume we can still do that in a followup on trunk? Or just get rid of sink flushing altogether, better yet.

OK. Patch looks ok with the following caveats:
1) Don't do the PostReflowEvent in DidCauseReflow. That'd actually break things
on trunk, I think.
2) Use the nsAutoCauseReflowNotifier in VerifyIncrementalReflow.
3) File a bug on removing this stuff once we no longer have sink flushes (and
mark dependent on the bug on removing those; check with Henri for the bug#
and whether we have one).|

I can't reproduce the crash on 1.9.1.0 but the problem is there. That I can confirm if I put a printf to the right place which shows that overstrict PresShell::IsSafeToFlush doesn't allow DocumentViewerImpl::InitPresentationStuff to flush.

Olli: So this looks mostly fixed (it's no longer #1), but the topcrash is still appearing for some number of users. This stack signature is #16 overall for Firefox 3.0.12 (with far, far fewer crashes than 3.0.11 had). Should I spin a new bug for this or is there something obvious that was missed?
