[Dovecot] kqueue rewrite testing, try #3
by Timo Sirainen 18 Aug '06

18 Aug '06

So, apparently the original kqueue code was working fine after all, although it was much more complex than it really needed to be. So, this time there's a really simple and pretty kqueue implementation: http://dovecot.org/nightly/dovecot-latest.tar.gz Tested that it seems to work with FreeBSD.

[Dovecot] 1.0rc7 getting near
by Timo Sirainen 18 Aug '06

18 Aug '06

To avoid having some stupid new problems with 1.0rc7, could you test this night's snapshot once it arrives in a couple of hours: http://dovecot.org/nightly/dovecot-20060811.tar.gz Especially people who had compiling problems with 1.0rc6. Also everyone who are still experiencing hangs could you try the suggestions in this mail and tell me what happened: http://dovecot.org/list/dovecot/2006-August/015377.html

[Dovecot] BSD people, please test kqueue changes
by Timo Sirainen 17 Aug '06

17 Aug '06

I rewrote much of the kqueue code since the old code didn't handle properly the case when both input and output I/O handlers were added to the same file descriptor with different callbacks. This is done commonly in Dovecot, so I'm wondering why more people didn't complain about problems with it.. :) I don't anyway have access to any BSDs so the code is completely untested. Please test how it works before 1.0rc7 :) http://dovecot.org/nightly/dovecot-latest.tar.gz I'd guess the hangs caused by recent RC versions were because the default was to use notify=kqueue instead of notify=none. I changed this back to none unless --with-ioloop=kqueue is used. There are a couple of things in the code that I'm not completely sure of. The kqueue() manual page says that EV_ADD "modifies" the event if it already exists. What exactly does that mean? Does it mean that the filter is replaced, or that it's ORed into the existing one? The same question for the EV_DELETE, does it delete everything or only those filters given in parameters? The code currently assumes ORing and EV_DELETE deleting only the given filters, since this is what the original code also did. I suppose the data and udata parameters don't matter in EV_DELETE since they weren't given originally in ioloop-notify-kqueue.c either, so I left them that way.

[Dovecot] BSD kqueue testing, once more before 1.0rc7
by Timo Sirainen 17 Aug '06

17 Aug '06

I did a few more changes and it seems to be working with FreeBSD. I didn't before realize that event filters weren't bitmasks so that broke things. Anyway, a bit more "real world testing" would be better than my test program and telnet localhost -tests :) I'll release 1.0rc7 in any case today before I go to sleep (so, max. 6 hours or so). http://dovecot.org/nightly/dovecot-latest.tar.gz

[Dovecot] LDAP usernames with spaces
by Tim Schafer 17 Aug '06

17 Aug '06

I'm trying to setup dovecot to work with an existing virtual user database in LDAP in order to replace courier-imap. I have users in LDAP with dn of the following form cn=Firstname Lastname,ou=company,dc=domain,dc=com and the uid attribute containes a userid of the form flastname The on disk format for an account is: /home/exim/<uid>/.maildir My first problem is that I cannot get dovecot to authenticate the existing DNs It complains: dovecot: auth(default): plain(?,ipaddress): Username contains disallowed characters I'm assuming it doesn't like the spaces. Any way around this? Also, I don't see any way to support the seperate username and userid where the username is for authentication and the userid is used for on disk pathname. Anyway to support this? Thanks in advance. -- Regards, Tim Schafer

[Dovecot] Mailbox isn't a valid mbox file (dovecot 1.0-0.beta8.2.fc5)
by FiL ＠ Kpoxa 17 Aug '06

17 Aug '06

Hello, I have upgraded my dovecot-0.99.13-3.FC3 to dovecot-1.0-0.beta8.2.fc5 recently and now am having weird problem. If somebody's mailbox has the first line in a form of From "User Name" <user(a)host.domain.edu> Thu Oct 7 14:20:00 1999 instead of From user(a)host.domain.edu Thu Oct 7 14:20:00 1999 then that mailbox couldn't be precessed by dovecot. It wasn't a problem with 0.99.13, but it is a problem with 1.0. Is there any fix for that on a dovecot's side? I don't like the idea of going through all 100Gb of mailboxes and fixing the From line. Thank you, FiL
