210465 - In "Cookie Manager" if I choose "Remove All Sites" it locks my computer up for about 10 minutes, cannot do ANYTHING, then it returns control

Status: RESOLVED DUPLICATE of bug 226511

(Core :: Networking: Cookies, defect)

Description

[Ken Beal]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.4) Gecko/20030612
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.4) Gecko/20030612

In "Cookie Manager" if I choose "Remove All Sites" it locks my computer up for
about 10 minutes, cannot do ANYTHING, then it returns control.

I even tried Ctrl+Alt+Del and "t" for the Task Manager, so I could kill it, and
the Task Manager never appeared.  Once it finally relinquished control, I had 3
Task Managers in the Task Bar.

And the Task Manager icon in the System Tray was pegged at 100% for the duration
of the lockup.

Reproducible: Always

Steps to Reproduce:
1. Go into Cookie Manager.
2. Click on "Remove All Sites" (you need a good 100 or 150 sites to do this).
3. Notice the system locking up for 10 minutes while it clears the sites.

Actual Results:  
It locks the machine completely for 10 minutes.

Expected Results:  
It should clear the sites immediately.  Or, if the operation takes longer than 5
seconds, it should give a pop-up saying "Please wait a minute" and even better
should give a progress bar so the user knows how long to wait.  (But a "delete"
operation SHOULD BE immediate, should not have to wait for anything, so it
appears that it's doing major calculations after deleting each site...)

Same thing happens for me, except: 
* I did not wait 10 minutes to see what would happen.
* I was able to get the task manager with no problem and End Task. (This shut
down Mozilla completely.)

I didn't see this in Win98 when I was testing Mozilla 1.4/Netscape 7.1.

Can you try a new profile, or describe how many sites there were, etc? I think
we need more info.

adding perf keyword - cookiemanager UI has some really bad scaling behavior.

Comment 4

[Marc Rust]

I'm seeing this behavior as well on 1.5 RC2/WinXP. Just now tried it. No way
around it, except for the above-described disorderly exit (comment#1), and
manually deleting 'cookieperm.txt'

Comment 5

[[e-mail]]

how many sites did you have in your cookperm.txt?

Comment 6

[Marc Rust]

Quite a few. Probably >100

Comment 7

[[e-mail]]

that's not many :)

i would've expected this only for very large numbers (>1000)

if you're seeing this with ~100, it makes me think something else is wrong.
