Re: [Dovecot] Bug(?): LSUB returns empty string although subscribed

[Lukas Haase]

Hi,

Thank you for your reply (and the bad news ;-) )So the one solution for v1.2 is to use CONTROL=~/... in the public 
namespace and relinquish the shared keywords feature?
Regards,
Luke

It's a bug, yes. It's also already fixed in v2.1 code tree as a result
of large cleanups and fixes to mailbox/subscriptions listing.
Backporting the fixes to v2.0 (or even worse: v1.x) would probably be a
lot of trouble..

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
