1.8b2_2005060906 works
1.8b2_2005061006 fails
No idea what happened with Steve's testcase :)

With that regression range, I guess this could be a regression from bug 295983.
Comment 5 Boris Zbarsky [:bz] 2006-03-24 12:40:28 PST
Please do attach a usable testcase to the bug instead of hosting it somewhere else?

This is a pretty major regression....  I'll try to figure it out when I get back, I guess, if no one does by then.

Test case.

Open index.html in the browser.

bz: when you get a chance to look at this let us know if you still think it's safe and sane for the 1.8.0 branch
Comment 8 Frank Wein [:mcsmurf] 2006-03-29 04:22:41 PST
BTW: These assertions happen when clicking Button1 for the second time:
###!!! ASSERTION: Found more undisplayed content data after removal: 'context ==
 nsnull', file h:/mozilla/tree-main/mozilla/layout/base/nsFrameManager.cpp, line
###!!! ASSERTION: EndLoad called early: 'mWriteState == eNotWriting || mWriteSta
te == ePendingClose || mWriteState == eDocumentClosed', file h:/mozilla/tree-mai
n/mozilla/content/html/document/src/nsHTMLDocument.cpp, line 1031

And these when clicking on Button2 then:
###!!! ASSERTION: Found more undisplayed content data after removal: 'context ==
 nsnull', file h:/mozilla/tree-main/mozilla/layout/base/nsFrameManager.cpp, line
###!!! ASSERTION: nsHTMLDocument::Reset() - Wyciwyg Channel  still exists!: '!mW
yciwygChannel', file h:/mozilla/tree-main/mozilla/content/html/document/src/nsHT
MLDocument.cpp, line 426

But not sure how far those are related to a bad state in general, since the throbber does not stop spinning after clicking Button1 (this also happens in builds without that regression).

With seamonkey(2006040110-trunk/Win-2K), problem couldn't be created when fisrt click of button1(document.close&open, document.write content1/2) after Load folowed by several clicks fo butron2(write content3/4), but problem was re-created when second or later series of click of button1 and button2's(no assertion was observed).
Putting alert('Hello') between document.close() and was a effective workaround of this bug's phenomenon.
Seriarization of document.close() and is required?

Oh, it's a nice feature!
I can easily attach zip file as attachment of test cases.

The idea is really simple.  Since the close() and following write() have already terminated the mParser we set the termination function for, the termination function shouldn't mess with it.  That means the termination function should know what parser it's supposed to be terminating.

Note that I could _maybe_ have gotten to the document from the parser, but passing both in seems to be safer.

I do think this is safe for the branches.

With this fix we still get the undisplayed content assertions -- that's bug 332644.
