dovecot - Dec 2011 - 2.1.rc1 (056934abd2ef): virtual plugin mailbox search pattern

Hello Timo,

With dovecot 2.1.rc1 (056934abd2ef) there seems to be something wrong 
with virtual plugin mailbox search patterns.

I'm using a virtual mailbox 'unread' with the following
dovecot-virtual file

$ cat dovecot-virtual
*
    unseen

For testing propose I created the following folders with each containing 
one unread message

INBOX, INBOX/level1 and INBOX/level1/level2

2.1.rc1 (056934abd2ef)

1 LIST "" "*"
* LIST (\HasChildren) "/" "INBOX"
* LIST (\HasChildren) "/" "INBOX/level1"
* LIST (\HasNoChildren) "/" "INBOX/level1/level2"
* LIST (\HasChildren) "/" "virtual"
* LIST (\HasNoChildren) "/" "virtual/unread"
1 OK List completed.
2 STATUS "INBOX" (UNSEEN)
* STATUS "INBOX" (UNSEEN 1)
2 OK Status completed.
3 STATUS "INBOX/level1" (UNSEEN)
* STATUS "INBOX/level1" (UNSEEN 1)
3 OK Status completed.
4 STATUS "INBOX/level1/level2" (UNSEEN)
* STATUS "INBOX/level1/level2" (UNSEEN 1)
4 OK Status completed.
5 STATUS "virtual/unread" (UNSEEN)
* STATUS "virtual/unread" (UNSEEN 1)
5 OK Status completed.

Result: virtual/unread shows only 1 unseen message. Further tests showed 
it's the one from INBOX. The mails from the deeper levels are not found.

Downgrading to 2.0.16 restores the correct behavior:

1 LIST "" "*"
* LIST (\HasChildren) "/" "INBOX"
* LIST (\HasChildren) "/" "INBOX/level1"
* LIST (\HasNoChildren) "/" "INBOX/level1/level2"
* LIST (\HasChildren) "/" "virtual"
* LIST (\HasNoChildren) "/" "virtual/unread"
1 OK List completed.
2 STATUS "INBOX" (UNSEEN)
* STATUS "INBOX" (UNSEEN 1)
2 OK Status completed.
3 STATUS "INBOX/level1" (UNSEEN)
* STATUS "INBOX/level1" (UNSEEN 1)
3 OK Status completed.
4 STATUS "INBOX/level1/level2" (UNSEEN)
* STATUS "INBOX/level1/level2" (UNSEEN 1)
4 OK Status completed.
5 STATUS "virtual/unread" (UNSEEN)
* STATUS "virtual/unread" (UNSEEN 3)
5 OK Status completed.

Result: virtual/unread shows 3 unseen messages as it should

The namespace configuration is as following

namespace {
   hidden = no
   inbox = yes
   list = yes
   location    prefix    separator = /
   subscriptions = yes
   type = private
}
namespace {
   location = virtual:~/virtual
   prefix = virtual/
   separator = /
   subscriptions = no
   type = private
}

I've also tried this with location = virtual:~/virtual:LAYOUT=maildir++ 
leading to the same result.

Thanks,

Just tested this on 2.1.rc3 and this still doesn't work like in v2.0. It 
seems like the search stops at the first hierarchy separator. Is there 
anything in addition I can do to help fix this issue?

Thanks,

What mailbox format are you using? Maybe I fixed this with
