[Dovecot] v2.0.5 released
http://dovecot.org/releases/2.0/dovecot-2.0.5.tar.gz http://dovecot.org/releases/2.0/dovecot-2.0.5.tar.gz.sig
See the "ACL handling bugs" message for more details about the ACL merging bug.
* acl: Fixed the logic of merging multiple ACL entries. Now it works as
documented, while previously it could have done slightly different
things depending on the order of the entries.
* virtual: Allow opening virtual mailboxes that refer to non-existing
mailboxes. It seems that the benefits of this outweigh the lack of
error message when typoing a mailbox name.
+ Added some disk I/O optimizations to Maildir and index code. They're
especially helpful with short-lived connections like POP3.
+ pop3: Added pop3_fast_size_lookups setting.
- doveconf sometimes failed with complaining about missing ssl_key
setting, causing e.g. dovecot-lda to fail.
- lda: If there's an error in configuration, doveconf didn't exit with
EX_TEMPFAIL as it should have.
- sdbox: Fixed memory leak when copying messages with hard links.
- zlib + sdbox combination didn't work
- zlib: Fixed several crashes, which mainly showed up with mbox.
- quota: Don't crash if user has quota disabled, but plugin loaded.
- doveadm fetch uid was actually returning sequence, not uid.
- v2.0.4's subscription listing ignored (and logged a warning about)
subscriptions=no namespaces' entries in some configurations.
(So listing shared mailboxes' subscriptions could have been broken.)
- acl: Fixed crashing when sometimes listing shared mailboxes via
dict proxy.On Sat, Oct 2, 2010 at 12:30 AM, Timo Sirainen tss@iki.fi wrote:

Hi Timo,
For those playing with SIS, is there a difference between 2.0.5 and the hg version?

I've now updated dovecot-2.0-sis to contain latest changes from 2.0.5. (Ugh, and if anyone wonders, I accidentally first pushed the SIS changes to dovecot-2.0. Reverted them now, hopefully correctly.)
The main problem with SIS is still how to handle single-dbox. I think I'll change it so that the files will be in hash-mailboxguid-imapuid format rather than hash-attachmentguid. The main annoying thing with that is that it then requires locking during saving and copying. I had been thinking about possibly making dbox entirely lockless some day in future, but with SIS it wouldn't be possible. But I guess that's not too bad..
Hi,
It seems there is an FD leak in this version. The number of open file descriptors quickly raise after upgrading from 2.0.4. (I haven't got more time to look after the issue, it may be obvious from the diffs)

You may be probably ten steps ahead of me but I had a thought here which was to try using the "lsof" program to find out what object was associated with the leaked FDs, which might help finding where they are leaking from.

In which process?
service imap { client_limit = 8
This might not be the best idea. Connections can sometimes block on locks and such for a while and it then causes the other connections in the same process to hang.

Sorry, I had to quickly downgrade, dovecot ate more than 100k descriptors in some minutes... I just thought that there weren't too many changes between 4 and 5 and it's trivial from a diff where those descriptors can leak (maybe the pop optimization, that's what really spins here). Of course I will look after it in a more quiet time. service imap { client_limit = 8 This might not be the best idea. Connections can sometimes block on locks and such for a while and it then causes the other connections in the same process to hang. I was worried about it too, but so far it seems to handle the load nicely. BTW, it would be nice to have some basic or advanced statistics about service times, it would be great to monitor that, and would also help to size those settings in a real system (finding the balance between in-process parallelism and the number of worker processes).

I guess it's because you had autocreate plugin enabled and autosubscribe entries. It shouldn't have been writing anything to logs then though, I'll fix that too.
