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 X). I've tested both pop3 and imap with no probl...

...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 got: Nov 29 16:46:27 mail dovecot: master: Panic: kevent(events=74, ts=59.1000000000) failed: Invalid argument Looking through the code, the panic is triggered in io_loop_handler_run_internal().?

Hi, The sample program given below freezes my 5.1R installation. This program is from a bug report - kern/54331. That bug report (http://lists.freebsd.org/pipermail/freebsd-bugs/2003-July/001608.html) is for the shutdown function call, whereas my machine basically just freezes up and reboots on kevent itself. I am also noticing this problem with another program i wrote (but too long to include here). Here is my uname output FreeBSD marvin 5.1-RELEASE FreeBSD 5.1-RELEASE #0: Fri Aug 1 16:14:43 GMT 2003 root@:/usr/obj/usr/src/sys/EC5 i386 thank you in advance, Krishna Sample Program: #...

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, 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.
