308781 - CSS @import makes document.write start a new document (was: http://news.com.com/ appears blank on trunk)

Status: VERIFIED FIXED

(Core :: DOM: HTML Parser, defect)

Description

[Jesse Ruderman]

Mozilla/5.0 (Macintosh; U; PPC Mac OS X Mach-O; en-US; rv:1.9a1) Gecko/20050915
Firefox/1.6a1

Steps to reproduce:
1. Go to http://news.com.com/.

Result: Page is blank.  Title bar is initially popuplated with the page's title,
but reverts to just "Deer Park Alpha 2" when I switch tabs and switch back (!?).
 Status bar says "Transferring data from secure-us.imrworldwide.com".

Filing as UNCO because I haven't tried to make a simple testcase.

Without looking at the page's source, I suspect a poorly timed document.write call.

Comment 2

Attachment: somewhat simpler page that demonstrates the problem about 40% of the time

Sorry, bug 264811, rather.

I don't think so.  I see this both before (nightly) and after (my own build) the
checkin for that bug.

Between 1.9a1_2005090908 and 1.9a1_2005090921 (can't get to show the bug in
1.9a1_2005090908 but sometimes in 1.9a1_2005090921).
Seems to have something to do with clearing cache. :)

In 2005091316 OS/2 trunk the throbber never stops if I try to load the testcase.
The statusbar is blank, and the tab says loading. Trying to view its source gets
me a blank window and a persisting hourglass. news.com.com seems to work fine.

Comment 13

[Jesse Ruderman]

I can reproduce (both at http://news.com.com/ and using the testcase) on
Windows, so setting OS to All.

Comment 14

[Ria Klaassen (not reading all bugmail)]

A simple "Reload" makes no difference, but I never see the problem after a
browser restart when  when http://news.com.com/ is already in the cache.

[Martijn Wargers (dead)]

I think this is a regression from bug 272702.

Comment 16

[Blake Kaplan (:mrbkap) (inactive)]

Oops, Martijn is right on. This is mine.

Attachment: Respect requests to block the parser

The NS_OK from CloseHead() was causing us to forget that the content sink had
asked us to block the parser for the <style> (and probably <script>, too) load.
