Hi, the attached patch contains these changes: 2005-12-15 22:18 Vaclav Haisman <v.haisman@sh.cvut.cz> * src/lib/ioloop-kqueue.c: Fix IO_ERROR behaviour. * src/lib/ioloop-notify-kqueue.c: New file. * configure.in: Improve kqueue detection and handling. Cleanup. The configure.in changes that are not related to kqueue are there to make autoconf 2.59, automake 1.9.6 and libtool 1.5.20 are happy. The directory change no...

...were produced from buildworld. However, now I notice that the client (dccm in this case -- www.rhyolite.com/dcc ) slowly uses all the descriptors on the box and must be restarted. I started logging it's use of descriptors over time via a shell script and lsof, and found that it's leaking kqueue descriptors. Has anyone: 1. noticed this problem with other libmilter linked clients that you may be running. 2. have some ideas on how to track down this leakage? I've looked at the dccm source and it seems to be using milter correctly (as it was working fine with an older version...

...s about 200 simultaneous connections to it running on freebsd 7. The machine has stayed up for about 8 days before it panics but sometimes panics after about 24 hours. We are running a PAE kernel (with ULE scheduler) as the machine has 2 (4 core processors) and 8gb of ram, dovecot is compiled with kqueue support which i suspect is causing the panics. We are currently trying with a GENERIC kernel to see if this addresses the issue but looking back through the dovecot lists there seems to be some issue with kqueue, freebsd and dovecot, i am tempted to simply disable kqueue in dovecot but am not sure...

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 an...

Hi, I've seen some chatter on NFS boards about kqueue being more reliable than inotify when used in NFSv3 and NFSv2. The chatter is a bit old so I don't know if it is true anymore. Anyone have pro/con experience with dovecot on the inotify/kqueue question when using NFS storage? I realize that kqueue is probably a bit slower and causes some d...

Apparently Dovecot with kqueue ioloop enabled causes random crashes in FreeBSD 9.1. Anyone else noticed something like that? I'm wondering if Dovecot's kqueue code has a bug somewhere (I can't find it) or could it be that FreeBSD itself has a bug? Anyway it seems to be returning events for filters that have already b...

Hi, I would like to submit the attached patch. It implements IO loop using FreeBSD's kqueue/kevent syscalls. It is based on snapshot of CVS HEAD as of 2005-12-12. I could only give it limited testing on FreeBSD 5.4 but it works fine so far.

Hello, attached patch adds experimental ioloop handler which uses BSD kqueue API. It compiles and survives my small test program, but not thoroughly tested because I have no suitable BSD machine to torture. Brave owners of (Free|Net|Open)BSD please test and report results :) Best regards. -- Andrey Panin | Linux and UNIX system administrator pazke at donpac.ru | PGP k...

Hey, I noticed that there was an ioloop "module" (if we can call it that) for select and poll and decided to add one for kqueue (aka kevent) BSDs high performance descriptor multiplexing API. I haven't done any of the configure glue stuff but the code is complete and works well. kqueue is available on all recent versions of FreeBSD, NetBSD, OpenBSD and Darwin (and therefore MacOS X). I've tested both pop3 and imap w...

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. -------------- next part -------...

I posted some questions a few months back and received lots of great help in getting my dovecot/postfix/LDAP setup working. Initially, I ran into the pipe failed too many open files error. I am running this setup on OpenBSD/sparc64 4.1-stable and so I put dovecot in its own class and upped the maxfiles setting for that class. This was back with dovecot 1.0 and everything worked fine.
