dovecot port needs configure.args="--with-ioloop=select"

[dave@…]

despite what [46949] says, at least the darwin9 variant of dovecot can't use the kqueue ioloop because of ​http://lists.apple.com/archives/Darwin-userlevel/2008/Dec/msg00010.html

I reproduce the problem easily with:

#!/bin/sh
$ /opt/local/sbin/dovecot --exec-mail imap
Fatal: kevent(EV_ADD, 0) failed: Operation not supported

Seeing the output there presumes you've got log_path = /dev/stderr in dovecot.conf.

Actually, that setting seems to fail also in a different way :(

I also tried substituting dovecot-1.2, to no avail Now trying dovecot-1.3

If kqueue doesn't work, neither will poll - they are based on the same mechanism.

select should work, assuming that's an option.

Replying to toby@…:

It's true that poll doesn't seem to work either, although it does get further before failing.

select should work, assuming that's an option.

I didn't see that as one of the configure options, but dovecot dot darwinports dot com seems to indicate that it has been used, so trying it now. At least the configure step hasn't failed yet.

Yep, it works! So I guess I had the wrong prescription: port should be changed to use "configure.args=--with-ioloop=select"

btw, darwinports dot com is a domain squatter - do not give them ad revenue

I was just broken by an upgrade :(. I holpe this gets fixed soon!

[dave@…]

Note this other weird thing: when I build with "configure.args=--with-ioloop=select," dovecot expects its configuration file to be /opt/local/etc/dovecot.conf, but otherwise it expects /opt/local/etc/dovecot/dovecot.conf

Dave: Do you know if this is still an issue with Mac OS 10.6 and darwin kernel 10.4.0? I'm not duplicating your described error in that environment.

[dave@…]

I don't know, sorry. Not running dovecot at the moment.

Long since fixed.
