Re: [Dovecot] 1.2.6 Spurious pread()/stream errors/index corruption
OK I'm still getting the same errors, so just as a test I tried the same process on an x86_32 build host, it's binaries now give a different error, one which I have also seen mentioned before I think:
banshee-x86-32 / # /NOC4/dovecot/sbin/dovecot -F Error: Missing auth section for server default Fatal: Invalid configuration in /NOC4/etc/dovecot/dovecot.conf
I do notice this though, with x86_64 binaries strace shows calls to pread() with x86_32 binaries strace shows calls to pread64()
this looks round the wrong way? hmm
in both builds file offset bits is 64, with config.h:
---- config.h check... /* Define to 1 if you have the `pread' function. */ /* Defint if pread/pwrite implementation is broken */ #define PREAD_BROKEN 1 /* Define if pread/pwrite needs _XOPEN_SOURCE 500 */

Oh! libmysqlclient messes this up. Why is your dovecot binary (and other binaries) linked against libmysqlclient? That's not normal. I did fix this in v2.0 though, the patch probably applies to v1.2 too: http://hg.dovecot.org/dovecot-2.0/rev/910059d94bbc
after ensuring that the main dovecot binaries were not linked against mysqlclient and applying this patch from 2.0: http://hg.dovecot.org/dovecot-2.0/rev/910059d94bbc all problems were fixed in 32 & 64bit x86 linux On Thu, 15 Oct 2009 18:59:50 -0400, Timo Sirainen <tss@iki.fi> wrote:
