Description

aio_suspend is not currently implemented in FreeBSD.

configure finds aio.h, but also seems not to use "linux-aio":


[...]
checking for lua... yes
checking for LUA... yes
checking for libaio... no
checking for library containing aio_suspend... none required
checking aio.h usability... yes
checking aio.h presence... yes
checking for aio.h... yes
checking for library containing crypt... -lcrypt
[...]
enabled:
  auth-crypt
  compress-bzip2
  compress-deflate
  compress-gzip
  large-files
  network-openssl
  regex-conditionals
disabled:
  auth-ldap
  linux-libaio
  network-ipv6
  stat-cache-fam
  storage-gdbm
  storage-memcache
  webdav-locks
  webdav-properties

Manually editing config.h (removing HAVE_AIO_H) works around this and reverts to the previous behaviour: it dumps on the first requested page.

can you compile it with debugging turned on.

This is what I use on my linux computer:
CFLAGS=" -g3 -O " CXXFLAGS=" -g3 -O " ./configure --enable-maintainer-mode

I only use linux but I might be able to find the problem, if you do another backtrace
with debugging turned on.

Sure, here it goes:

BTW: It seems that aio_suspend is implemented really, but must must be loaded into the kernel with kldload aio (it also lacks to recognize the need for -pthread in the last link step).

I have attached a patch that should fix this bug.
  1. cd lighttpd/
  2. patch -p0 <../lighttpd-1.5.0-kqueue.diff
  3. make

That patch changed the segfault to:


Program received signal SIGSEGV, Segmentation fault.

    at server.c:1673

If I can debug it further to provide more infos, please tell me how.

I have changed the patch. You will need to revert the changes from the old patch.

svn revert src/fdevent_freebsd_kqueue.c

Confirmed as working, I guess it can be committed.

Jan or someone with write access to svn will need to commit the patch.

Also did you need to make any changes to get aio_suspend to work?
