mod_perl 1.99_16 tests fail on OpenBSD due to low open files limit
FYI, I just discovered after much pain and suffering that the mod_perl
test suite fails to run on OpenBSD 3.5 because it tries to open more
than 64 files at once.
To duplicate, try this on your OpenBSD box:
$ sudo ktrace -d /usr/local/apache2.0.50-modperl1.99_16/bin/httpd -d \
/export/src/mod_perl-1.99_16/t -f
/export/src/mod_perl-1.99_16/t/conf/httpd.conf -D APACHE2 -X

[Wed Aug 25 09:49:40 2004] [error] Can't load Perl module TestFilter::in_str_consume for server localhost.orslut.com:8529, exiting...
---
Perl can't load TestFilter/in_str_consume.pm because it can't open
the file -- as evidenced in the ktrace dump:
16641 httpd NAMI "/export/src/mod_perl-1.99_16/t/lib/TestFilter/in_str_consume.pmc"
16641 httpd RET stat -1 errno 2 No such file or directory
16641 httpd CALL open(0x3cdae100,0,0)
16641 httpd RET open -1 errno 24 Too many open files
This problem can be resolved by increasing the open file limit to 128:
$ ulimit -n 128
I hope this helps someone down the road!
Regards,
Ken

Thanks Ken. I've adopted your report in the troubleshooting section:

Non blocking mode is not actually being set despite the call to
opt_set().

On certain platforms, yes, introduced by Apache 2.0.50 I believe as a fix
to some security issue.

I'm not following you, Ken, what seems to be the problem?

BTW -- just noticed that there's some documentation saying that the
socket needs to be set to nonblocking mode to avoid this error (the
"Resource temporarily unavailable" error).
But the test scripts do set non blocking mode. I wonder if perhaps
it's not working inside Apache?
