similar to: kqueue freezing 5.1R on kevent call

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.

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

Hi, 2.2.25 crashes on FreeBSD with a kqueue-related message. I see references to something similar (http://www.dovecot.org/list/dovecot/2012-February.txt) from a couple years ago. I get: Jul 1 10:07:27 imap dovecot: master: Panic: kevent(EV_ADD, READ, 54) failed: Bad file descriptor It's not dumping core, and I get the message even with "protocols =" Downgrading back to 2.2.24

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 key: wwwkeys.pgp.net

The attached patch should fix the problem with dying imap on "Unrecognized event". The problem is that when we register a handle for IO_ERROR only, we still can get readable/writable event without EV_EOF being set. This case was not handled. -- Vaclav Haisman -------------- next part -------------- An embedded and charset-unspecified text was scrubbed... Name: io-kq.diff URL:

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

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

Hello I've been seeing these panics with dovecot 2.2.31 (and older versions) under FreeBSD about once every 2-3 months or so.? I know it's been discussed here in the list, but I didn't see a definitive fix.? If it's been fixed, please ignore this post (sorry!). I finally managed to observe the bug on a server that has the patch that prints out the kevent() timespec values and

Two issues came up for me when building 2.1beta1 on OS X (10.5.8 on PPC). The first was already mentioned in an earlier thread by a BSD user (http://dovecot.org/list/dovecot/2011-September/061201.html). I just wanted to point out that the error is still occurring in spite of a new test for GNU ld in the configure script. I needed to remove "-no-undefined" specifically:
