130424 - edit menu takes a long time to open

Status: RESOLVED WORKSFORME

(Toolkit :: Form Manager, defect, P2)

Description

[John Flynn]

From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:0.9.9) Gecko/20020310
BuildID:    2002031008

Open the mentioned URL, or any really long Slashdot article in nested mode. The
edit menu and context menu take a long time to open, and the browser hangs
during this delay.

One Mozilla thread is CPU bound during the time the browser is hung. Upon
stracing this thread, there is no syscall activity. I suspect a very large data
structure is being walked.

Reproducible: Always
Steps to Reproduce:
1.Go to the above URL or a very long slashdot article.
2.Try to open the edit menu or context menu.


Actual Results:  Observe hung browser. Observe that browser does not respond to
additional UI events until hang is complete.

Expected Results:  Edit or context menu should open within a reasonable amount
of time (under half a second)

System config:

Redhat 7.2 on a Pentium III 600, 384MB of RAM, Linux kernel 2.4.17

Attachment: HTML that triggers the delay

I just noticed that I have moderator access on /., and each article has a
dropdown list associated with it that lets you vote on the article. This may be
related, as the problem didn't ocurr before I had moderator access. Attached is
the HTML from the page which exhibits the problem.

->xpt/menus.  

Comment 4

[John Morrison]

Thanks for the example of the moderator's slashdot page. 

-> Forms Manager; this is the forms manager code right? (and I think there is a 
dup of this bug).

[Stephen P. Morse]

This was actually a dup of bug 77073, except that that one explicitly mentioned 
the context menu and only deep into the comments of the report was the edit menu 
mentioned as well.  I just closed out that bug report because wallet items no 
longer appear on the context menu.  So this report shall remain as the defining 
bug report for slowdown on the edit menu, and I'll remove the mention of context 
menu from the summary line.
