[Dovecot] Folder renaming oddities.

[Tan Shao Yi]

Hi Timo,

We are observing some weird behaviour when we try to rename an inferior 
folder, followed by the superior folder.

These folders have an asterisk in the name.

* LIST (\HasChildren)   "." "*Own Family"
* LIST (\HasChildren)   "." "*Own Family.Tour"
* LIST (\HasNoChildren) "." "*Own Family.Maid"
* LIST (\HasNoChildren) "." "*Own Family.Tour.NZ"
a OK List completed.

a rename "*Own Family.Tour.NZ" "Own Family.Tour.NZ"
a OK Rename completed.
a LIST "" *
* LIST (\HasChildren)   "." "*Own Family"
* LIST (\HasNoChildren) "." "*Own Family.Tour"
* LIST (\HasNoChildren) "." "*Own Family.Maid"
* LIST (\HasNoChildren) "." "Own Family.Tour.NZ"
a OK List completed.

a rename "*Own Family.Tour" "Own Family.Tour"
a rename "*Own Family.Tour" "Own Family.Tour"a NO Internal error 
occurred. Refer to server log for more information. [2007-10-02 11:02:59]
a LIST "" *
* LIST (\HasChildren)   "." "*Own Family"
* LIST (\HasNoChildren) "." "*Own Family.Maid"
* LIST (\HasChildren)   "." "Own Family.Tour"
* LIST (\HasNoChildren) "." "Own Family.Tour.NZ"


dovecot: Oct 02 11:02:59 Error: IMAP(XXX): rename(/XXX/Maildir/.*Own 
Family.TourNZ, /XXX/Maildir/.Own Family.TourNZ) failed: No such file or 
directory


It seems that the renaming of the folder succeeds, though the "a NO 
Internal error occurred" is reported.

However, when the folders do not have an asterisk in the name.

* LIST (\HasChildren)   "." "Own Family"
* LIST (\HasNoChildren) "." "Own Family.Maid"
* LIST (\HasChildren)   "." "Own Family.Tour"
* LIST (\HasNoChildren) "." "Own Family.Tour.NZ"

a rename "Own Family.Tour.NZ" "*Own Family.Tour.NZ"
a OK Rename completed.

a rename "Own Family.Tour" "*Own Family.Tour"
a OK Rename completed.

a LIST "" *
* LIST (\HasChildren)   "." "Own Family"
* LIST (\HasNoChildren) "." "Own Family.Maid"
* LIST (\HasChildren)   "." "*Own Family.Tour"
* LIST (\HasNoChildren) "." "*Own Family.Tour.NZ"

The rename operation completes successfully with no error.

Is there something that I am doing wrong?

P.S., Will it be possible to also request the mail-log plugin to log 
rename operations too? :)

Thanking in advance.

Cheers,
