PerlOutputFilterHandler does not work

[Vladimir Volovich <vv...@vsu.ru>]

Hello,

I installed apache2.0 with mod_perl2.0 taken two days ago from cvs.
I need to use new filters support available in version2.0 of apache
and mod_perl, but i have a problem with filters.

i tried to use the supplied test filter which comes with
modperl-2.0/t/filter/TestFilter/lc.pm:

added
<Location /test>
  PerlOutputFilterHandler TestFilter::lc
</Location>

and installed the TestFilter::lc module:

#============================
package TestFilter::lc;

use strict;
use warnings FATAL => 'all';

use Apache::Filter ();

sub handler {
    my $filter = shift;

    while ($filter->read(my $buffer, 1024)) {
        $filter->print(lc $buffer);
    }

    0;
}
#============================

but apache always closes the connection whenever i access files in
/test, and even does not print anything into the error_log. :(

could someone confirm that this works or not?

Please Cc: to my email.

Thanks,
v.

the TestFilter::lc module is working fine in the test suite, so i'm not
sure what the problem is.  can you puts some warn()s in there to see if
the filter is actually being called?
you can also build with perl Makefile.PL MP_DEBUG=1 then configure:
PerlTrace f
or
PerlTrace all
to get some tracing info from modperl.

can you access the files in /test without the PerlOutputFilterHandler
configure?
