Status: RESOLVED WORKSFORME

(MailNews Core :: Networking: IMAP, defect)

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.1.3) Gecko/20090824 Firefox/3.5.3
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.1.5pre) Gecko/20091020 Shredder/3.0pre

When deleting an IMAP folder while TB is downloading headers for that folder, TB will try to access the folder after it's deleted and will show one popup for each message in the folder.

Reproducible: Always

Steps to Reproduce:
1. Have an IMAP folder with new, unread messages
2. Click the folder
3. While TB is still downloading the headers, delete the folder

Actual Results:  
After TB finishes downloading the headers, it will pop up an error message saying "The current command did not succeed. The mail server responded:Mailbox doesn't exist: <name of folder>". Closing this popup brings up another, identical one. This happens once for each message in the folder.

Expected Results:  
TB should not try to access the folder after it got deleted, and shouldn't show any popups.

I couldn't reproduce with Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.5; en-US; rv:1.9.1.5pre) Gecko/20091020 Shredder/3.0pre what I did is slighly different :

1) created a new account
2) while thunderbird was downloading I deleted a folder.
3) No popups

On #1, I'll check next time it happens. I don't have any folder with enough messages at the moment.

On #2, did you make sure that TB was actively downloading the headers for the specific folder you deleted?  It's not enough for TB to be downloading something, it has to be the headers for the folder you're deleting.

No, so it's per folder.

On #1: error console remains empty

And it appears I may be slightly off in the specifics. It looks like the problem is when it's downloading the actual messages, not the headers. So this probably only happens when "Keep messages for this account on this computer" is checked.

So an additional sequence that triggers it is:

1) click folder with a bunch of new mesages
2) TB downloads headers
3) TB starts downloading messages in the background
4) Delete folder
5) Get one popup for each message not yet downloaded

Some more details from when it just happened again, this time back to the original delete-while-downloading-headers variety:

1) click folder
2) TB starts downloading headers
3) Delete folder
** 4) TB keeps downloading headers in background; progress messages (x of y headers downloaded) show up in the status bar
** 5) TB briefly shows "deleted <folder>" in status bar
** 6) TB shows "opening <folder>" in status bar
** 7) TB shows "Downloading x of y in <folder>"
** 8) popup

Jochen, does this reproduce with version 3.1?

Comment 9

[Jochen De Smet]

No longer a significant issue.

Using: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.2.15) Gecko/20110303 Thunderbird/3.1.9

The error message has been moved from a popup to a non-modal notification in the bottom right-hand corner. I _think_ it now only shows it once per folder, but either way since it now goes away automatically it does not impede normal use.

Feel free to mark this fixed.
