Hello
I'm using Apache2 and ModPerl2 on Fedora Core 4 x86_64 and I discover some
problem when client try to get nonexistent script uri
(http://my.site.com/foooooo.pl).
Client doesn't obtain any response or error page.

1. Problem Description:
When I try to execute script, which doesn't exist, I get errors like this:
slurp_filename('/uis/web/nonexistent.pl') / opening: (2) No such file
or directory at
/usr/lib64/perl5/vendor_perl/5.8.6/x86_64-linux-thread-multi/ModPerl/RegistryCooker.pm
line 540
Can't use an undefined value as a SCALAR reference at
/usr/lib64/perl5/vendor_perl/5.8.6/x86_64-linux-thread-multi/ModPerl/RegistryCooker.pm
line 578
and client doesn't obtain any response. Any code in sub read_script after line
'self->{CODE} = eval { $self->{REQ}->slurp_filename(0) }; # untainted'
is not proceeded.
So I made little work around putting
return Apache2::Const::NOT_FOUND unless -e $self->{FILENAME};
before problem line.
related apache configuration:
<Files *.pl>
Options +ExecCGI
SetHandler perl-script
PerlResponseHandler ModPerl::Registry
PerlOptions +ParseHeaders +GlobalRequest +MergeHandlers +SetupEnv
</Files>
