1.24 to 1.24_01 spinning httpds on startup (solved)

[Michael J Schout <ms...@gkg.net>]

About a month or 2 ago, I had posted a problem where I tried to upgrade from:

Redhat Linux 6.2,
perl 5.6.0
Apache 1.3.12
mod_perl 1.24
mod_ssl 2.6.6

to 

Redhat Linux 6.2
perl 5.6.0
Apache 1.3.14
mod_perl 1.24_01
mod_ssl 2.7.1

And reported that after doing this, my httpds would spin on startup.  When I
turned on MOD_PERL_TRACE=all, it was showing that it was stuck in an infinite
loop processing configuration stuff.  I posted the mod_perl trace for it as
well.

I have finally gotten a chance to revisit this and it turns out that what was
causing problems was that I had in my httpd.conf:

<Perl>
$PerlRequire = '/some/path/file.pl';
</Perl>

Changing this to:

<Perl>
    push @PerlRequire, '/some/path/file.pl';
</Perl>

Fixed the problem under 1.24_01 for me and everything appears to be kosher now.

Maybe the behavior of PerlRequire has changed between 1.24 and 1.24_01?  

Anyways, I wanted to post this to the list in hopes that this might help others
who may have stumbled onto this problem.

Regards,
Mike

Hmn... Happens to me too after upgrading from 1.24 to 1.24_01
(Apache 1.3.12).

I don't see any changes to the Perl configure code...

<Perl>
 $PerlRequire = '/tmp/startup.pl';
</Perl>

$ cat /tmp/startup.pl
warn "works?";
1;

this has been fixed in the cvs tree.
