[Dovecot] imap crash "Message count decreased" (1.1.4)

During crash coredumpsize was set to 0, so there is no dump and no gdb backtrace. Maybe the log entry is still helpful: Oct 10 16:10:41 b6:Uruguay dovecot: imap[21184]: user=<yayo(a)87.77.208.77>, Disconnected for inactivity in reading our output bytes=339/191358 Oct 10 16:10:41 b2:Uruguay dovecot: Panic: imap[21184]: user=<yayo(a)87.77.208.77>, Message count decreased Oct 10 16:10:41 b3:Uruguay dovecot: imap[21184]: user=<yayo(a)87.77.208.77>, Raw backtrace: imap [yayo(a)87.77.208.77 130.133.4.83] [0x80cf615] -> imap [yayo(a)87.77.208.77 130.133.4.83] [0x80cfe6e] -> imap [yayo(a)87.77.208.77 130.133.4.83](i_fatal+0) [0x80cf78f] -> imap [yayo(a)87.77.208.77 130.133.4.83](imap_sync_deinit+0xec) [0x8068e9a] -> imap [yayo(a)87.77.208.77 130.133.4.83] [0x805a9fa] -> imap [yayo(a)87.77.208.77 130.133.4.83] [0x805ad26] -> imap [yayo(a)87.77.208.77 130.133.4.83](client_command_cancel+0x83) [0x805f6a0] -> imap [yayo(a)87.77.208.77 130.133.4.83](client_destroy+0xed) [0x805f904] -> imap [yayo(a)87.77.208.77 130.133.4.83] [0x806053d] -> imap [yayo(a)87.77.208.77 130.133.4.83] [0x80d823b] -> imap [yayo(a)87.77.208.77 130.133.4.83](io_loop_handle_timeouts+0x19) [0x80d8295] -> imap [yayo(a)87.77.208.77 130.133.4.83](io_loop_handler_run+0x94) [0x80d8f2a] -> imap [yayo(a)87.77.208.77 130.133.4.83](io_loop_run+0x35) [0x80d82d7] -> imap [yayo(a)87.77.208.77 130.133.4.83](main+0xbc) [0x806be4c] -> /lib/tls/i686/cmov/libc.so.6(__libc_start_main+0xc8) [0xb7dcaea8] -> imap [yayo(a)87.77.208.77 130.

[Dovecot] Problem with namespaces
by Tim Bishop 16 Oct '08

16 Oct '08

[1.1.4 with http://hg.dovecot.org/dovecot-1.1/rev/b61424a50786 applied] I'm trying to use namespaces as described here for UW-IMAP compatibility: http://wiki.dovecot.org/Namespaces But I'm getting a problem with the hidden namespaces showing up in the LIST output. Here is a simplified transcript. The ~/Mail folder contains just two folders. The config given to imapd is as follows: MAIL=mbox:/home/cut/jru2/Mail:INBOX=/home/cut/jru2/.mail:INDEX=/var/state/dovecot-indexes/jru2 NAMESPACE_1=mbox:/home/cut/jru2/Mail:INBOX=/home/cut/jru2/.mail:INDEX=/var/state/dovecot-indexes/jru2 NAMESPACE_1_INBOX=1 NAMESPACE_1_LIST=1 NAMESPACE_1_PREFIX= NAMESPACE_1_SEP=/ NAMESPACE_1_SUBSCRIPTIONS=1 NAMESPACE_1_TYPE=private NAMESPACE_2=mbox:/home/cut/jru2/Mail:INBOX=/home/cut/jru2/.mail:INDEX=/var/state/dovecot-indexes/jru2 NAMESPACE_2_HIDDEN=1 NAMESPACE_2_LIST=0 NAMESPACE_2_PREFIX=mail/ NAMESPACE_2_SEP=/ NAMESPACE_2_SUBSCRIPTIONS=0 NAMESPACE_2_TYPE=private I would expect the second namespace not to be listed. But it is: in: 2 LIST "" "*" 3 LOGOUT out: * OK [RAWLOG TIMESTAMP] 2008-10-16 15:41:40 * LIST (\NoInferiors \UnMarked) "/" "folder" * LIST (\NoInferiors \UnMarked) "/" "test" * LIST (\NoInferiors \Marked) "/" "INBOX" * LIST (\Noselect \HasChildren) "/" "mail" * LIST (\NoInferiors \UnMarked) "/" "mail/folder" * LIST (\NoInferiors \UnMarked) "/" "mail/test" 2 OK List completed. * BYE Logging out 3 OK Logout completed. That's with hidden turned on, and the list option turned off. Am I missing something with my config? Tim. -- Tim Bishop http://www.bishnet.net/tim/ PGP Key: 0x5AE7D984

[Dovecot] Virtual Domains and Master Users
by Roderick A. Anderson 16 Oct '08

16 Oct '08

Can I have a master users list for each virtual domain? I'm not sure from what I read on the page: http://wiki.dovecot.org/Authentication/MasterUsers auth default { mechanisms = plain login CRAM-MD5 passdb passwd-file { args = /var/mail/vhosts/%d/passwd.masterusers master = yes pass = yes } passdb passwd-file { args = username_format=%n /var/mail/vhosts/%d/passwd } userdb passwd-file { args = username_format=%n /var/mail/vhosts/%d/passwd } ... } TIA, Rod --

[Dovecot] dovecot 1.2: dict no longer really support DICT_ITERATE_FLAG_RECURSE
by Bernhard Herzog 16 Oct '08

16 Oct '08

Hi, In dovecot 1.1, I could use DICT_ITERATE_FLAG_RECURSE when iterating over a dict to retrieve all entries that start with a given prefix. This doesn't seem to work anymore in the new dict implementation in dovecot 1.2. Looking at the SQL queries actually generated, it seems as if dovecot 1.1 used to generate queries that use pattern matching (key LIKE "my/prefix/%") whereas dovecot 1.2 does not, so it's no wonder that it doesn't work in 1.2. This probably has to do with the pattern matching for dict keys in the config file. It would be enough for my purposes at the moment -- i.e. getting the metadata plugin to work with dovecot 1.2 -- if recursion were only possible for the last of fields in the pattern.

[Dovecot] dovecot 1.1.4 maildir imap segfault in message_parse_header_next
by Diego Liziero 16 Oct '08

16 Oct '08

I've tried to stress test dovecot 1.1.4 with imaptest for days without any assertion failure or crash. Just some "got too little data" messages. So far it's the most stable 1.1.x version. Today a user got this imap segfault with vanilla 1.1.4 (I don't know if it's something you have already fixed in current tree). The user didn't complain of anything, I've just found the error in the logs and the core file. Regards, Diego. ---- Core was generated by `/usr/libexec/dovecot/imap'.

[Dovecot] deliver does not work with new shared namespaces in dovecot 1.2
by Sascha Wilde 16 Oct '08

16 Oct '08

Hi Timo, checking my new userdb-checkpassword back end is stumbled across the fact, that the new shared namespace definitions possible in dovecot stop deliver from working. The log says: Oct 15 14:37:43 burlywood3 <info> deliver(2(a)burlywood3.rgb)[24502]: Namespace: type=shared, prefix=users/%%u/, sep=/, inbox=no, hidden=no, list=no, subscriptions=no Oct 15 14:37:43 burlywood3 <error> deliver(2(a)burlywood3.rgb)[24502]: Namespace 'users/': shared: Shared namespace prefix contains unknown variables Oct 15 14:37:43 burlywood3 <critical> deliver(2(a)burlywood3.rgb)[24502]: Fatal: Namespace initialization failed I guess the primary (only?) case where these shared namespaces are needed for delivery is the use of sieve. cheers sascha -- Sascha Wilde OpenPGP key: 4BB86568 http://www.intevation.de/~wilde/ http://www.intevation.de/ Intevation GmbH, Neuer Graben 17, 49074 Osnabrück; AG Osnabrück, HR B 18998 Geschäftsführer: Frank Koormann, Bernhard Reiter, Dr. Jan-Oliver Wagner
