Bug in libapreq makes form elements stick to an apache child

[Jeffrey Baker]

Hi,

I haven't had time to really hunt this bug to its source, but here is
the report anyway.

Take as an example the URI /program?foo=bar&foo=baz&foo=quux

In program, which uses libapreq, I have code which looks like this:

my @foo_in = $r->param('foo');

@foo_in should not be defined if there are no foo arguments in the query
string.  The problem is that once a foo argument has been seen, the
@foo_in array is defined in that Apache child process for all time.  The
array will not be defined in any other Apache child.

To reproduce the problem, use the handler I have included below and
perform the following steps:

1) Visit /yoururl
2) Visit /yoururl?foo=bar&foo=baz
3) Visit /yoururl as many times as you have Apache child processes

Here is the handler:

package JWB;
use Apache::Request;

use strict;

sub handler {
        my $r = Apache::Request->new(shift());
        $r->status(200);
        $r->content_type("text/plain");
        $r->send_http_header;

        my @foo_in = $r->param('foo');

        if (defined @foo_in) {
                print "foo_in is defined!\n";
        }
        else {
                print "foo_in is not defined!\n";
        }

        print "foo_in has this many entries: ",scalar(@foo_in);

        return 0;
}

1;

Regards,
Jeffrey
