[Dovecot] Bug(?): LSUB returns empty string although subscribed (was: Re: Cannot subscribe to shared folders)

16 Feb 2011


      Hi,
I did further investigation on this issue (using raw IMAP commands) and
I think that this is a bug...

Hi,
I am unable to subscribe to shared folders (...)
everything seems to be correct (dovecot 1.2).
My configuration is the following (maybe that is the problem?!):
namespace private {
separator = .
prefix =
inbox = no
list = no
hidden = yes
location = maildir:~/Maildir-root
subscriptions = yes
}
namespace private {
separator = .
prefix = INBOX.
inbox = yes
subscriptions = yes
}
namespace public {
separator = .
prefix = Shared.
location = maildir:/var/mail/shared:INDEX=~/Maildir/shared:LAYOUT=fs
subscriptions = YES / NO <--
}
[...]
In each case I make sure that all folders are subscribed, that is, the
subscribe command returns OK and the subscribed folders are written into
/var/mail/shared/subscriptions and ~/Maildir-root/subscriptions,
respectively. Just to make sure:
# cat /var/mail/shared/subscriptions
NoSpamDrop
Public
SpamDrop
# cat /home/lukas/Maildir-root/subscriptions
Shared.NoSpamDrop
Shared.Public
Shared.SpamDrop
#
It turns out that if I set
1.) subscriptions = yes (in the public namespace above)
the lsub command behaves correct:
 . list "" "Shared.*"
 * LIST (\HasNoChildren) "." "Shared.NoSpamDrop"
 * LIST (\HasNoChildren) "." "Shared.Public"
 * LIST (\HasNoChildren) "." "Shared.SpamDrop"
 . OK List completed.
 . lsub "" "Shared.*"
 * LSUB () "." "Shared.NoSpamDrop"
 * LSUB () "." "Shared.Public"
 * LSUB () "." "Shared.SpamDrop"
 . OK Lsub completed.
 . logout
 * BYE Logging out
 . OK Logout completed.
 closed
2.) ...but with subscriptions = no
the lsub command returns an empty list ALTHOUGH the folders are
subscribed:
 . list "" "Shared.*"
 * LIST (\HasNoChildren) "." "Shared.NoSpamDrop"
 * LIST (\HasNoChildren) "." "Shared.Public"
 * LIST (\HasNoChildren) "." "Shared.SpamDrop"
 . OK List completed.
 . lsub "" "Shared.*"
 . OK Lsub completed.
 . logout
 * BYE Logging out
 . OK Logout completed.
Now I am pretty sure that this is a bug. Maybe it is better to file a
bug report?
Best regards,
Luke
