481142 - Renamed folders in IMAP account appears both with original and new name

Status: NEW

(MailNews Core :: Networking: IMAP, defect)

Description

[Luigi Rosa]

User-Agent:       Mozilla/5.0 (X11; U; Linux x86_64; en-GB; rv:1.9.0.6) Gecko/2009020911 Ubuntu/8.10 (intrepid) Firefox/3.0.6
Build Identifier: 3.0b2

Renaming an IMAP folder with another client causes TB to display both old and new name in folder list

Reproducible: Always

Steps to Reproduce:
1. Start TB and connect to IMAP account
2. Switch to another client (webmail or another instance of TB) and rename a subfolder
3. Go back to TB and refresh the subfolder list
Actual Results:  
You see the renamed folder twice, both the old name and the new one

Expected Results:  
Old name should not be displayed, in face clicking in it gives an error.

I verified this bug in latest 2.0, in 3.0b2 and in today nigtly build.

See attached IMAP.RAR; I created this subtree:

shredder
 \ -sh level1 a
   \ -sh level2 11
     -sh level2 2
     -sh level2 zz
   -sh level1 b
   -sh level1 c


Renaming "sh level2 zz" to "sh level2 3" in TB 2.0 causes displaying BOTH "sh
level2 zz" and "sh level2 3" in Shredder. 

This bug hapens in TB 2.0 when I rename "sh level2 11" in Shredder.

I could observe the phenomenon with Tb trunk.
> Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.1b3pre) Gecko/20090302 Shredder/3.0b3pre
 - Gmail IMAP is used. (Note: Bug 470650 is not relevant when Gmail IMAP case)
 - Concurrent access by Seamonkey 1.1.14, Tb trunk, and Gmail Web Interface.
 - Rename/Delete by Seamonkey or Gmail, while Tb trunk is accessing Gmail IMAP.

Old folder(renamed or deleted by other) disappeared many times after next.
 1. Open a folder, and subsribe => old folder is not listed => Refresh
    (If login is not done yet, subscribe displays nothing. Already known bug.)
 2. Restart Tb. (If not effective, repeat 1 & 2 several times)
I'm not sure that this is currently available/effective recovery procedure.

I did my tests using Dovecot IMAP server; I think that this particular bug is not related to server software.

I tested again with Tb trunk 2009/3/07 build, using Gmail IMAP.
> Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.1b4pre) Gecko/20090307 Shredder/3.0b3pre

> Folder name : Test-003/X-03
1. Open Test-003/X-03 by Tb trunk.
2. Rename Gmail Label of Test-003/X-03 to Test-003/X-03-A (== folder rename)
3-A. Show subscribed folder only = Not checked
     => X-03 & X-03-A at folder pane
3-B. Show subscribed folder only = Checked
     => X-03 only at folder pane
4. Collapse Test-003 & expand Test-003 gain
   => Nothing is changed at folder pane
5. Collapse IMAP account and & expand IMAP account again
   => X-03-A only at folder pane.

Improved by patch for Bug 472129?
