Description Sanford Selznick 2013-02-07 19:30:56 PST
Created attachment 187220 [details] Sample 1. Visit http://nightly.webkit.org/start/trunk/142133 2. Reload the page 3 times. After the third reload the page will never load again until Safari/WebKit are quit and relaunched. I don't think this is a duplicate of the very old https://bugs.webkit.org/show_bug.cgi?id=19420 I can reproduce this on at least two machines/users. It seems to happen on pages with dynamic HTML. Sample provided, but it's not really hanging, just blank. 10.8.2, Version 6.0.2 (8536.26.17, 537+)

I tried but was unable to reproduce this problem. My configuration is similar but not identical.

Just reproduced it on a fairly bare-bones third computer using the exact link http://nightly.webkit.org/start/trunk/142133 and reloading three times. After the third reload the page goes blank. Not all pages exhibit the problem. I also switched to a different network. Same problem I asked a far-away friend to try. Same problem.

Created attachment 187575 [details] Movie of the blank reload Watch the attached movie to see version, time, and date reproducing the event.

What browser extensions do you have installed? Have you tested without them?
Comment 5 Sanford Selznick 2013-02-11 10:11:17 PST
Just to clarify my setup: -> No browser extensions installed anywhere. -> I downloaded the current nightly build to perform the test on all the computers. -> All computers are up to date to 10.8.2. -> Stock-Safari works fine on all systems. -> Reloading the URL in the movie (and in the bug report) reproduces the problem *almost* always. -> There's nothing in Console.app about the issue. -> I've tried a variety of computers and networks. Thanks!
Comment 6 Sanford Selznick 2013-02-11 10:12:10 PST
I do have Flash installed on all systems, and have silverlight installed on most systems.
Comment 7 Alexey Proskuryakov 2013-02-12 19:18:00 PST
I can reproduce 100% reliably.
Comment 9 Sanford Selznick 2013-02-14 21:04:08 PST
This appears to be fixed on two of my systems now.
Comment 10 Alexey Proskuryakov 2013-02-14 21:32:13 PST
Bisecting shows that this got fixed by <http://trac.webkit.org/changeset/142707>.
Comment 11 Alexey Proskuryakov 2013-02-14 21:34:44 PST
Unsure what to think about it though. Does this mean that main resource loading no longer takes this code path, but the bug still exists for subresources?
Comment 12 Sanford Selznick 2013-02-15 06:56:59 PST
I don't know enough to say. Sorry.
Comment 13 Sanford Selznick 2013-02-18 08:35:20 PST
This bug, exactly as described by this report, reappeared in WebKit 143213. Sorry. Three reloads kills it. The only way out is to quit/re-run WebKit.app.

Who can reproduce this?
Comment 15 Sanford Selznick 2013-02-18 19:37:36 PST
It's intermittent. I reproduced it a few times today.
Comment 16 Alexey Proskuryakov 2013-02-18 20:39:10 PST
I can not reproduce now.

Comment 19 Sanford Selznick 2013-02-21 10:13:47 PST
No, It happens at random times and random sites. I haven't seen a pattern.
Comment 20 Sanford Selznick 2013-03-05 07:06:09 PST
I've marked this as resolved. I'll reopen it if I can get it to happen again at other URLs. The initial problem is definitely fixed, though! Thank you!
