227087 - Throbber spins forever when image.src is changed by script

Status: RESOLVED FIXED

(Core :: Layout: Images, Video, and HTML Frames, defect)

Description

[Kenneth Hopping]

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.6a) Gecko/20031029
Build Identifier: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.6a) Gecko/20031029

In an application with three frames, I am experiencing continuous scrolling of
the progress indicator when I dynamically modify the img.src attribute. The
problem seems to occur after two of the companion frames are reloaded to update
dynamic information content.

Reproducible: Always

Steps to Reproduce:
1.I have a simplified test app that demonstrates the problem.
2.
3.

Actual Results:  
Image completes loading but progress indicator continues to scroll and scroll
and ...

Expected Results:  
Scrolling should stop when image is finished loading.

I can supply the test app as a .tar file if this problem is worth investigating.

So... if I remove the code in update_info, there is no bug.  But update_info is
NOT getting called, as far as I can see....

Is the problem here that the window.location.reload() confuses the loadgroup's
count of pending loads?

Dup of bug 143398?

Not clear...  Someone needs to actually debug this to see why we think the page
is still loading...

Also occurs on Windows with Firefox 1.0.1.  Taking QA.

Attachment: Smaller one-frame testcase.

For those who care about such things, I was able to reproduce the bug with this
smaller single frame testcase.

I'm running into this issue with the new error pages when I do the following:

1) Launch FF (Latest build)
2) Load one tab pointing to http://forums.mozillazine.org/viewtopic.php?t=303519
3) Load a second tab pointing to
http://bonsai.mozilla.org/cvsquery.cgi?branch=HEAD&branchtype=exact&date=week 
4) Verify that both tabs have loaded completely and that the throbber is not
animated/spinning.  
5) Load a third tab and type abouf:cache  (yes, I typed abouF:cache)
6) You should notice that the throbber spins and never stops as well as the stop
icon is enabled but you can't stop the "page load".  The other two tabs inherit
this behavior as well!

Probably fixed by fix for bug 315056.

Testcase WFM (the top image shrinks and the throbber isn't moving)
