[Dovecot] imap search/content-transfer-encoding assertion failed

11 Nov '07

When performing an imap search, I hit the following assertion failure: imap(vmail): Panic: file unichar.c: line 128 (uni_ucs4_to_utf8_c): assertion failed: (chr <= 0x40000000) imap(vmail): Error: Raw backtrace: /usr/lib/dovecot/imap [0x80c7f7f] -> /usr/lib/dovecot/imap [0x80c7d6a] -> /usr/lib/dovecot/imap [0x80d8616] -> /usr/lib/dovecot/imap(uni_utf8_to_decomposed_titlecase+0x9f) [0x80d892f] -> /usr/lib/dovecot/imap(message_decoder_decode_next_block+0x679) [0x80c46e9] -> /usr/lib/dovecot/imap(message_search_more+0x3e) [0x80c2e8e] -> /usr/lib/dovecot/imap(message_search_msg+0x72) [0x80c3012] -> /usr/lib/dovecot/imap [0x8093f47] -> /usr/lib/dovecot/imap [0x80b7719] -> /usr/lib/dovecot/imap(mail_search_args_foreach+0x32) [0x80b77c2] -> /usr/lib/dovecot/imap(index_storage_search_next_nonblock+0x243) [0x8093af3] -> /usr/lib/dovecot/imap [0x805cdc7] -> /usr/lib/dovecot/imap [0x805d138] -> /usr/lib/dovecot/imap(io_loop_handle_timeouts+0x112) [0x80ce892] -> /usr/lib/dovecot/imap(io_loop_handler_run+0x66) [0x80cf316] -> /usr/lib/dovecot/imap(io_loop_run+0x28) [0x80ce768] -> /usr/lib/dovecot/imap(main+0x4ab) [0x806675b] -> /lib/tls/i686/cmov/libc.so.6(__libc_start_main+0xc8) [0xb7e68ea8] -> /usr/lib/dovecot/imap [0x8059141] My quick analysis: This seemed to be caused by a single message in this mailbox.

[Dovecot] assertion failed: (mailbox_list_is_valid_existing_name(_list, name))
by Adam McDougall 11 Nov '07

Do you need a gdb backtrace for this one? I'm not sure why all of a sudden this started happening, its probably due to me adding a folder somewhere? not sure. It happened when I went to open my folder subscriptions in thunderbird. It was taking longer than usual (call this phase 1) and I noticed this in the logs: (cant remember if this was phase 1 or 2 but the error is probably the same) Nov 11 00:38:38 boomhauer dovecot: imap-login: Login: user=<mcdouga9>, method=PLAIN, rip=208.53.102.126, lip=35.9.37.190, TLS Nov 11 00:38:39 boomhauer dovecot: IMAP(mcdouga9): fchown(/egr/mail/shared/decs/temp.boomhauer.3050.af3db3ac545170a7) failed: Operation not permitted Nov 11 00:38:44 boomhauer dovecot: IMAP(mcdouga9): file mailbox-list-maildir.c: line 186 (maildir_list_get_path): assertion failed: (mailbox_list_is_valid_existing_name(_list, name)) Nov 11 00:38:44 boomhauer dovecot: child 3050 (imap) killed with signal 6 Nov 11 00:38:45 boomhauer dovecot: imap-login: Login: user=<mcdouga9>, method=PLAIN, rip=208.53.102.126, lip=35.9.37.190, TLS Nov 11 00:38:45 boomhauer dovecot: IMAP(mcdouga9): fchown(/egr/mail/shared/decs/temp.boomhauer.3052.5538be060c2f9c7d) failed: Operation not permitted Nov 11 00:38:46 boomhauer dovecot: IMAP(mcdouga9): file mailbox-list-maildir.c: line 186 (maildir_list_get_path): assertion failed: (mailbox_list_is_valid_existing_name(_list, name)) Nov 11 00:38:46 boomhauer dovecot: child 3052 (imap) killed with signal 6 When I cancelled the subscription window, "phase 2" is the same thing but happening more rapidly.

[Dovecot] Outlook can't see namespace folders
by James 10 Nov '07

10 Nov '07

Hi guys i understand that you can't subscribe to the Prefix names of namespace folders right now with dovecot. But for instance if i user outlook express and it can't see the prefix name then it can't see the subfolders of that "prefix folder" either. So even though it can detect and see the subfolders it won't display them cause it can't see the "parent" Is there any fix for this? it's also kind of annoying in thunderbird but at least you can still see the subfolders. TIA James Here's my config # /etc/dovecot/dovecot.conf protocols = imap imaps pop3 pop3s log_timestamp = "%Y-%m-%d %H:%M:%S " first_valid_uid = 100 login_user=vmail mail_extra_groups = mail mail_debug = yes pop3_uidl_format = %08Xu%08Xv mail_location = maildir:/home/vmail/domains/%n/Maildir #default_mail_env = maildir:/home/vmail/domains/%n/Maildir auth default { mechanisms = plain passdb ldap { args = /etc/dovecot/dovecot-ldap.conf } userdb ldap { args = /etc/dovecot/dovecot-ldap.conf } } # maildir namespace private { separator = / prefix = location = maildir:/home/vmail/domains/%n/Maildir inbox = yes hidden = no } # mbox namespace private { separator = / prefix = "Mbox/" location = mbox:/home/vmail/domains/%n/Mbox inbox = no hidden = no } #public spam folder namespace public { separator = / prefix = /Spam/ location = maildir:/home/vmail/domains/Spam/Maildir/ hidden = no } ssl_disable = no ssl_cert_file = /etc/ssl/certs/dovecot.pem ssl_key_file = /etc/ssl/private/dovecot.pem ssl_verify_client_cert = no ssl_cipher_list = ALL:!LOW:HIGH:MEDIUM:+SSLv2:RSA

[Dovecot] Request for variable unique to each server?
by Adam McDougall 10 Nov '07

10 Nov '07

I've been looking for a variable I can use in my dovecot.conf within the INDEX= setting so I can have one index dir per imap server on NFS. I've been looking at http://wiki.dovecot.org/Variables but no variable seems to contain something like server hostname, and I've been hunting for the variable expansion code in dovecot but haven't been able to find it. %l (local IP) won't help me because when using our load balancer, %l is the same IP on all of my servers. %r is close to useful but having a local webmail server on each server means I'd end up with 127.0.0.1 being shared (also I would end up with one directory per unique user/clientIP combo). Is there a variable that holds the server hostname or something else unique per server, or could one be added, or could someone point me at the code? Thanks.

[Dovecot] UTF-8 in dovecot-sieve ?
by Arthur Pétry 10 Nov '07

10 Nov '07

Hi, Reading http://tools.ietf.org/html/rfc3028#section-2.7.2 I thought that out-of-the-box dovecot can filter messages by matching header in UTF-8. But when I tested it, it failed : (I'm using 1.0.5 with sieve plugin) Here is my .dovecot.sieve file : ---------- require ["fileinto", "imapflags"]; if allof(header :contains "subject" "filtre") { addflag "test_1"; } if allof(header :contains "subject" "là") { addflag "test_2"; } if allof(header :comparator "i;ascii-casemap" :contains "subject" "hé") { addflag "test_3"; } ---------- Only the first of the three rules do work. When I try to match a subject string with accent encoded in ISO-8859 like "hélà" : "=?ISO-8859-1?Q?h=E9l=E0?=" there is no match Am I doing something wrong ?

[Dovecot] 1.0beta7 still has SEARCH TEXT not search the FROM
by Asheesh Laroia 10 Nov '07

10 Nov '07

I just tried out 1.0beta7 and erased all my indexes and with fts and fts_squat enabled, and when I SEARCH TEXT in Dovecot, it does *not* find messages where the thing I SEARCH for appear only in the From: header. Timo, can you confirm or deny that you still see this behavior? I did clear my indexes before doing it. -- Asheesh. -- Man is the measure of all things. -- Protagoras

[Dovecot] Dovecot I/O scheduling (all versions)
by mikkel＠euro123.dk 08 Nov '07

08 Nov '07

I have experienced this on all versions of Dovecot that Ive used (1.0 - 1.1b6) using IMAP (its difficult to test if its also there with POP3). What I see is that if there is a peak in disk usage at the time of a specific request that requests stalls. The saturation of disk I/O is momentary but when its done (maybe after one or two seconds) Dovecot still waits for its I/O operation instead of continuing as soon as resources are available. Now, I would expect Dovecot to only wait until there are resources available and not stall for at long time (sometimes it stalls for like 10 seconds, and sometimes completely). This could be OS specific (Im using ZFS and Solaris 10 on Sparc) but it may also be due to the way dovecot is programmed. Theres always plenty of RAM and CPU available so thats not whats causing troubles. Is anyone else familiar with this issue? Regards, Mikkel
