bug renameing/deliting special use folders in murder setup.

[Michael Menge]

Hi,

we discovered a bug in cyrus imapd 3.0.8 in murder/aggregator configuration.

We have the following default stucture:

a LIST "" "*"
* LIST (\HasNoChildren) "/" INBOX
* LIST (\HasChildren) "/" Mail
* LIST (\HasNoChildren \Drafts) "/" Mail/drafts
* LIST (\HasNoChildren) "/" Mail/s-spam
* LIST (\HasNoChildren \Sent) "/" Mail/sent
* LIST (\HasNoChildren \Trash) "/" Mail/trash
* LIST (\HasNoChildren \Junk) "/" Mail/v-spam
a OK Completed (0.000 secs 7 calls)

ctl_mboxlist -d | grep ^user.zrstes1
user.zrstes1	1 ma05.mail.localhost!ssd zrstes1	lrswipkxtecdan
user.zrstes1.Mail	1 ma05.mail.localhost!ssd zrstes1	lrswipkxtecdan
user.zrstes1.Mail.drafts	1 ma05.mail.localhost!ssd zrstes1	lrswipkxtecdan
user.zrstes1.Mail.s-spam	1 ma05.mail.localhost!ssd zrstes1	lrswipkxtecdan
user.zrstes1.Mail.sent	1 ma05.mail.localhost!ssd zrstes1	lrswipkxtecdan
user.zrstes1.Mail.trash	1 ma05.mail.localhost!ssd zrstes1	lrswipkxtecdan
user.zrstes1.Mail.v-spam	1 ma05.mail.localhost!ssd zrstes1	lrswipkxtecdan

Renaming/Deleting a Mailbox with Special-Use Flag fails

b RENAME Mail/v-spam Mail/spam
b NO SPECIAL-USE flag conflict
c DELETE Mail/v-spam
c NO SPECIAL-USE flag conflict

but Renaming/Deleting the Folder above will succeed

d RENAME Mail Test
* OK rename Mail Test
* OK rename Mail/drafts Test/drafts
* OK rename Mail/s-spam Test/s-spam
* OK rename Mail/sent Test/sent
* OK rename Mail/trash Test/trash
* OK rename Mail/v-spam Test/v-spam
d OK Completed

but results in broken entries in the mailboxdb on mupdate master and frontends

ctl_mboxlist -C /etc/imapd_fe.conf -d | grep ^user.zrstes1
user.zrstes1	1 ma05.mail.localhost!ssd zrstes1	lrswipkxtecdan
user.zrstes1.Mail.drafts	1 ma05.mail.localhost!
user.zrstes1.Mail.sent	1 ma05.mail.localhost!
user.zrstes1.Mail.trash	1 ma05.mail.localhost!
user.zrstes1.Mail.v-spam	1 ma05.mail.localhost!
user.zrstes1.Test	1 ma05.mail.localhost!ssd zrstes1	lrswipkxtecdan
user.zrstes1.Test.drafts	1 ma05.mail.localhost!ssd zrstes1	lrswipkxtecdan
user.zrstes1.Test.s-spam	1 ma05.mail.localhost!ssd zrstes1	lrswipkxtecdan
user.zrstes1.Test.sent	1 ma05.mail.localhost!ssd zrstes1	lrswipkxtecdan
user.zrstes1.Test.trash	1 ma05.mail.localhost!ssd zrstes1	lrswipkxtecdan
user.zrstes1.Test.v-spam	1 ma05.mail.localhost!ssd zrstes1	lrswipkxtecdan

see the missing partition for old names of the special use folders.
it seams that the sepecial use annotation was moved with the folders without
a problem

e LIST (SPECIAL-USE) "" "*"
* LIST (\HasNoChildren \Drafts) "/" Test/drafts
* LIST (\HasNoChildren \Sent) "/" Test/sent
* LIST (\HasNoChildren \Trash) "/" Test/trash
* LIST (\HasNoChildren \Junk) "/" Test/v-spam
e OK Completed (0.000 secs 7 calls)

On the backend the mailboxdb entries look fine. But the user is unable  
to rename/move the folders back,
or create the new folders with the old name because the folder are  
still reserved on the mupdate server.

f RENAME Test Mail
* OK rename Test Mail
* NO rename Test/drafts Mail/drafts: unable to reserve mailbox on  
mupdate server
f NO unable to reserve mailbox on mupdate server
g LIST "" "*"
* LIST (\HasNoChildren) "/" INBOX
* LIST (\HasNoChildren) "/" Mail
* LIST (\HasNoChildren \Drafts) "/" Test/drafts
* LIST (\HasNoChildren) "/" Test/s-spam
* LIST (\HasNoChildren \Sent) "/" Test/sent
* LIST (\HasNoChildren \Trash) "/" Test/trash
* LIST (\HasNoChildren \Junk) "/" Test/v-spam
g OK Completed (0.010 secs 7 calls)

a "ctl_mboxlist -m -a" on the backend will fix the mailboxdb on the  
mupdate master/frontend

I am not sure if moving a special use folder should work or not this  
should be consistent to
renaming a top folder.

At the moment our users are unable to restore their folder structure if they
renamed/moved their folders unintended.
