[Dovecot] 1.0.rc23 released
http://dovecot.org/releases/dovecot-1.0.rc23.tar.gz http://dovecot.org/releases/dovecot-1.0.rc23.tar.gz.sig
Documentation is probably the only important thing left before v1.0.
* deliver doesn't ever exit with Dovecot's internal exit codes anymore.
All its internal exit codes are changed to EX_TEMPFAIL.
* mbox: X-Delivery-ID header is now dropped when saving mails.
* mbox: If pop3_uidl_format=%m, we generate a unique X-Delivery-ID
header when saving mails to make sure the UIDL is unique.
+ PAM: blocking=yes in args uses an alternative way to do PAM checks.
Try it if you're having problems with PAM.
+ userdb passwd: blocking=yes in args makes the userdb lookups be done
in auth worker processes. Set it if you're doing remote NSS lookups
(eg. nss_ldap problems are fixed by this).
+ If PAM child process hasn't responded in two minutes, send KILL
signal to it (only with blocking=no)
- IMAP: APPEND ate all CPU while waiting for more data from the client
(broken in rc22)
- mbox: Broken X-UID headers assert-crashed sometimes
- mbox: When saving a message to an empty mbox file it got an UID
which immediately got incremented.
- mbox: Fixed some wrong "uid-last unexpectedly lost" errors.
- auth cache: In some situations we crashed if passdb had extra_fields.
- auth cache: Special extra_fields weren't saved to auth cache.
For example allow_nets restrictions were ignored for cached entries.
- A lot of initial login processes could cause auth socket errors
in log file at startup, if dovecot-auth started slowly. Now the
login processes are started only after dovecot-auth has finished
initializing itself.
- imap/pop3 proxy: Don't crash if the remote server disconnects before
we're logged in.
- deliver: Don't bother trying to save the mail twice into the default
mailbox (eg. if it's over quota).
- mmap_disable=yes + non-Linux was really slow with large
dovecot.index.cache files
- MySQL couldn't be used as a masterdb
- Trash plugin was more or less broken
- imap/pop3 couldn't load plugins if they chrooted
- imap/pop3-login process could crash in some conditions
- checkpassword-reply crashed if USER/HOME wasn't set
- Trash plugin was more or less broken
does this mean it should be working now ? with mboxes ? if it does, then I must be doing something wrong or not seeing any effects. Is it actually supposed to purge messages from folders listed in dovecot-trash.conf when dirsize quote is reached ?
dovecot.conf
protocol lda { ....... mail_plugins = cmusieve quota trash
protocol imap { ...... mail_plugins = quota imap_quota trash
.... trash = /usr/local/etc/dovecot-trash.conf

Found two bugs:
If you have multiple namespaces, it'll crash
Multiple trash mailboxes didn't work or crashed.

Hi Timo, i just tested the trash plugin, it works now in parts, which means , mail in trash is deleted, but the new one coming in is bounced
Command died with signal 11: "/usr/lib/dovecot/deliver"
removing trash makes the server acting corect
like this
Your message was automatically rejected by Dovecot Mail Delivery Agent.
The following reason was given: Quota exceeded

Could you get gdb backtrace from the crash? If you run ulimit -c unlimited before deliver, it should write a core file. Then see http://dovecot.org/bugreport.html

Actually I think this fixes it: http://dovecot.org/list/dovecot-cvs/2007-February/007835.html
If you had multiple trash mailboxes it could crash.

I'm seeing dovecot-auth in a pretty tight poll loop on rc23, which I have now deployed. It's not chewing up so much CPU that the machine can't deal, so I'll leave it alone for now. It looks like this:
truss -d -p 245083
.... 0.3679 pollsys(0x0005CF90, 6, 0xFFBFFAE8, 0x00000000) = 0 0.3686 pollsys(0x0005CF90, 6, 0xFFBFFAE8, 0x00000000) = 0 0.3779 pollsys(0x0005CF90, 6, 0xFFBFFAE8, 0x00000000) = 0 0.3786 pollsys(0x0005CF90, 6, 0xFFBFFAE8, 0x00000000) = 0 0.3978 pollsys(0x0005CF90, 6, 0xFFBFFAE8, 0x00000000) = 0 0.3982 pollsys(0x0005CF90, 6, 0xFFBFFAE8, 0x00000000) = 0 0.4080 pollsys(0x0005CF90, 6, 0xFFBFFAE8, 0x00000000) = 0 ...
[timestamps in column 1 are time elapsed since start of truss]
So what fd's are we polling?
truss -v poll -p 245083
... pollsys(0x0005CF90, 6, 0xFFBFFAE8, 0x00000000) = 0 fd=5 ev=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL rev=0 fd=0 ev=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL rev=0 fd=3 ev=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL rev=0 fd=7 ev=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL rev=0 fd=8 ev=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL rev=0 fd=9 ev=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL rev=0 timeout: 0.000000000 sec pollsys(0x0005CF90, 6, 0xFFBFFAE8, 0x00000000) = 0 fd=5 ev=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL rev=0 fd=0 ev=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL rev=0 fd=3 ev=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL rev=0 fd=7 ev=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL rev=0 fd=8 ev=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL rev=0 fd=9 ev=POLLIN|POLLPRI|POLLERR|POLLHUP|POLLNVAL rev=0 timeout: 0.009000000 sec
(timeout seems to oscillate back and forth between 0 and 0.009).
