1. Problem Description:
A custom apache config directive defined in a <Location> together with
a PerlResponseHandler makes the request handling crash (apache dumps core, see below).
Nothing printed in the error_log nor the access_log.
httpd.conf contains: -------------------- PerlLoadModule Xi::TestConf
<Location /test> XiTest test SetHandler modperl PerlResponseHandler Xi::Test </Location>
TestConf.pm: ------------ package Xi::TestConf;
use Apache2::Module ();
my @directives = ( { name => 'XiTest' } );
Apache2::Module::add(__PACKAGE__, [EMAIL PROTECTED]);sub XiTest {
my($self, $parms, $arg) = @_;
$self->{XiTest} = $arg;
}1;
Test.pm: -------- package Xi::Test;
use Apache2::RequestIO ();
use Apache2::Const -compile => qw/OK/;
sub handler {
my $r = shift; $r->print("Hello");return Apache::Const::OK; }
1;
See attached bug tarball.
