Dovecot news - Aug 2006 - 1.0 RC7 released

http://dovecot.org/releases/dovecot-1.0.rc7.tar.gz
http://dovecot.org/releases/dovecot-1.0.rc7.tar.gz.sig

Can everyone now agree that there are no more hangs? :)

	* Require that Dovecot master process's version number matches the
	  child process's, unless version_ignore=yes. Usually it's an
	  accidental installation problem if the version numbers don't match.
	* Maildir: Create maildirfolder file when creating new maildirs.

	+ ldap+prefetch: Use global uid/gid settings if LDAP query doesn't
	  return them
	+ %variables: Negative offsets count from the end of the string.
	  Patch by Johannes Berg.
	- kqueue ioloop code rewrite
	- notify=kqueue might have caused connection hangs sometimes
	- deliver: If message body contained a valid mbox From_ line, it
	  and the rest of the message was skipped.
	- mbox: We got into infinite loops if trying to open a 2 byte sized
	  file as mbox.
	- Don't crash with ssl_disable=yes
	- quota plugin caused compiling problems with some OSes
	- mbox: After saving a mail to a synced mbox, we lost the sync which
	  caused worse performance

I think my v1.0 TODO list is:

 - avoid duplicate flag change notifications, or in case the message is
   also expunged don't bother notifying its flag changes at all
   (shouldn't be hard)
 - HFS+ avoid-hardlinks patch?
 - 32bit -> 64bit upgrade still doesn't work without assert-crashing:
   mail-cache-transaction.c: line 709 (mail_cache_add): assertion failed:
   (fixed_size == (unsigned int)-1 || fixed_size == data_size)
 - Courier-compatible INBOX. namespace gives "invalid namespace"
errors

I'm still not sure about the last one though. Could someone give me
specific commands that clients send that causes it?

As for the 32bit -> 64bit upgrade fix, could someone give me access to a
x86-64 machine for a while to test it out?

Looks like you're close to 1.0 Timo. Just in time perhaps to make the 
the Fedora Core 6 release.

Actually I already do have, so forget about this. :)

What about this one?  The "Connection queue full" issue doesn't
appear to be entirely fixed.  In fact the fix was disconnecting so frequently
that I reverted to the non-fixed version:

Seems to be working well so far here (nothing post rc2 did until now!) 
on NetBSD/amd64 -current with checkpasswd, Maildir, and imaps.  Thanks 
for all the work Timo!

Compiled and installed on a Fedora 5 32bit with maildir.
No problem to report here.

Hi,

Thanks for the good work.

I am installing this on FreeBSD 6.1, with KQUEUE support, on
a server handling 3000+ users, so expect me to scream if it
doesn't perform ;)

It's been running for over 20 hours on FreeBSD 6.1, with
KQUEUE support. No glitches so far....

Great work, Timo!

To confirm: the functionality added since rc2 to do offset from the end of
a string using a negative number (e.g. "%-2.02i gives the UID mod
100")
seems to work OK in our case (which is that example!).

Many thanks.

No problems on OBSD 3.9 either - worked fine the whole day.

Timo,

My setup: Solaris 9 (soon to be 10), imap and imaps.  I had had
problems with rc4, rc5, rc6 and had remained at rc2.  rc7 died
a couple of hours after upgrading with the following syslog message:

Aug 18 10:45:01 emerald dovecot: [ID 920869 mail.error] Login process died 
too early - shutting down

I went in and doubled login_max_processes_count and login_max_connections
in the conf file, restarted, and it has stayed up since then.  I had
to double these two settings during beta releases but not the early rc
releases.

A more useful syslog message might help others, something like
"too many connections".

Dovecot 1.0rc7 seems to be running fine here on NetBSD 3.0.1 with kqueue
(pop3 + imap + imaps, pgsql-based user/pw).

Unfortunately, not. :(

I still see the occasional error in copying mail to the sent mailbox on
Thunderbird 1.5.0.5.

There is a change in behavior, though. Before rc7 when I got the error
for one message, all subsequent messages that I sent before restarting
TB would also fail on copy to the mailbox. Now in rc7, if I send another
message without restarting TB, the new message will likely be copied to
the sent mailbox without a problem.

my configure line:
./configure --without-shadow --localstatedir=/var  --with-ioloop=kqueue
--with-cyrus-sasl2 --without-gssapi --without-vpopmail
--prefix=/usr/local --build=i386-portbld-freebsd5.3

Thanks,
Todd

I concur!   FreeBSD 5.2.1 - plain old ./configure came up with:
io-loop=poll, file change =none. 

Been up for 3 days, about 17k logins.

There are packaged builds for i386/x86_64 Fedora Core/Red Hat

I see many people reporting that there are no more hangs for them and I
truly wish this were also the case for me. I thought it was just a crazy
user or two, but I saw it this morning with my own eyes :) So it is
happening still. 

Thunderbird 1.5.0.5

dovecot --version
1.0.rc7

dovecot --build-options
Build options: ioloop=poll notify=dnotify ipv6 openssl
SQL drivers: mysql postgresql sqlite
Passdb: checkpassword ldap pam passwd passwd-file shadow sql
Userdb: checkpassword ldap passwd prefetch passwd-file sql static

There is nothing that shows up on the log files (just like before, with
rc2) no errors, no timeouts, nothing. Suggestions and or ideas welcome. --Gabe
