not loading in freebsd jail

[baloo]

I'm trying to load mod_wsgi 2.6 in apache 1.3 running in a FreeBSD 7.2
jail.

httpd fails starting up with the message "Bad systemcall".

ktrace shows that the call was:
1941 httpd CALL ksem_init(0x7fffffffe910,0x1)
1941 httpd RET ksem_init -1 errno 78 Function not implemented


Disabling the mod_wsgi makes apache load again.
I've also tried enabling security.jail.sysvipc_allowed using sysctl
without luck.

Any solution to this?

I solved this problem which was not jail specific at all.
You simply have to add this to the kernel config and recompile it:
options P1003_1B_SEMAPHORES

Perhaps it should be possible to mension this in the error message
when trying to load?

Not possible as that original error message is likely generated by
something outside of both Apache and mod_wsgi.

BTW, be aware that support for Apache 1.3 after mod_wsgi 3.0 will
start to disappear. You really should consider using Apache 2.2.

Also, version 3.0 of mod_wsgi, provided you are using Apache 2.X, will
have an ability to chroot individual mod_wsgi daemon mode process
groups into different chroot environments, a possibly much more
flexible system than having to chroot the whole of Apache.

I've never run into such an issue while running in a jail using Apache
2.2 (I made the FreeBSD port USE_APACHE=1.3+ though). I'm not certain if
the host for my jail has that option, but on a different box without a
jail I don't have that option and everything works fine.
