Hello, ioloop->highest_fd is used by ioloop-select.c only, so its handling can be moved out of generic ioloop code. Attached patch (agains -test35) does exactly this. Please consider applying.

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, currently I'm working on new ioloop handler which uses epoll(4) API introduced in Linux kernel 2.6. In this API each fd added to fd set by epoll_ctl system call can be accompanied with user supplied data (integer or void pointer). epoll_wait syscall reports arrived events as an array of structures containing event mask and user data. Attached patch replaces fd and condition parameters

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

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

Hi, Can't find any notes about this in documentation. Is replication supposed to work between different versions of dovecot? I've just found that dovecot 2.2.33.1 was uploaded to debian unstable and it crashes on every replication with older dovecot 2.2.27. (version 2.2.32.1 was probably ok) Summary: - 2.2.33.1 crashes when replicating from/to 2.2.27 - 2.2.32.1 probably ok when

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 there, I get a crash when doing "make check" for version 2.3.0 on Solaris Sparc. The build was done with gcc 7.3.0.

I'm running Dovecot as proxy in front of some IMAP/POP3 Dovecot & Courier-IMAP servers and in the last couple of days I've been seeing a lot of imap-login crashes (signal 11) on both 2.2.18 and 2.2.25, all SSL related. The following backtraces are taken running 2.2.25, built from source on a test system similar to the live proxy servers. OS: CentOS 6.8 64bit Packages:

When in the process of testing out the 2.3.0 version of Dovecot, we noticed that on a busy server, imap-login can sometimes take 100% CPU and remain there indefinitely.
