Catalyst::Controller::WrapCGI - Run CGIs in Catalyst

=head1 SYNOPSIS

    package MyApp::Controller::Foo;

    use parent qw/Catalyst::Controller::WrapCGI/;
    use CGI ();

    sub hello : Path('cgi-bin/hello.cgi') {
        my ($self, $c) = @_;

        $self->cgi_to_response($c, sub {
            my $q = CGI->new;
            print $q->header, $q->start_html('Hello'),
                $q->h1('Catalyst Rocks!'),
                $q->end_html;
        });
    }

In your .conf, configure which environment variables to pass:

    <Controller::Foo>
        <CGI>
            username_field username # used for REMOTE_USER env var
            pass_env PERL5LIB
            pass_env PATH
            pass_env /^MYAPP_/
            kill_env MYAPP_BAD
        </CGI>
    </Controller::Foo>

=head1 DESCRIPTION

Allows you to run Perl code in a CGI environment derived from your L<Catalyst>
context.

B<*WARNING*>: do not export L<CGI> functions into a Controller, it will break
with L<Catalyst> 5.8 onward.

If you just want to run CGIs from files, see L<Catalyst::Controller::CGIBin>.

C<REMOTE_USER> will be set to C<< $c->user->obj->$username_field >> if
available, or to C<< $c->req->remote_user >> otherwise.

=head1 CONFIGURATION

=head2 pass_env

C<< $your_controller->{CGI}{pass_env} >> should be an array of environment variables
or regular expressions to pass through to your CGIs. Entries surrounded by C</>
characters are considered regular expressions.

=head2 kill_env

C<< $your_controller->{CGI}{kill_env} >> should be an array of environment
variables or regular expressions to remove from the environment before passing
it to your CGIs.  Entries surrounded by C</> characters are considered regular
expressions.

Default is to pass the whole of C<%ENV>, except for entries listed in
L</FILTERED ENVIRONMENT> below.

=head2 username_field

C<< $your_controller->{CGI}{username_field} >> should be the field for your
user's name, which will be read from C<< $c->user->obj >>. Defaults to
'username'.

See L</SYNOPSIS> for an example.

=cut

# Hack-around because Catalyst::Engine::HTTP goes and changes
# them to be the remote socket, and FCGI.pm does even dumber things.

open my $REAL_STDIN, "<&=".fileno(*STDIN);
open my $REAL_STDOUT, ">>&=".fileno(*STDOUT);

=head1 METHODS

=head2 cgi_to_response

C<< $self->cgi_to_response($c, $coderef) >>

Does the magic of running $coderef in a CGI environment, and populating the
appropriate parts of your Catalyst context with the results.

Calls L</wrap_cgi>.

=cut

sub cgi_to_response {
  my ($self, $c, $script) = @_;

  my $res = $self->wrap_cgi($c, $script);

  # if the CGI doesn't set the response code but sets location they were
  # probably trying to redirect so set 302 for them

  my $location = $res->headers->header('Location');

  if (defined $location && length $location && $res->code == 200) {
    $c->res->status(302);
  } else { 
    $c->res->status($res->code);
  }
  $c->res->body($res->content);
  $c->res->headers($res->headers);
}

=head2 wrap_cgi

C<< $self->wrap_cgi($c, $coderef) >>

Runs C<$coderef> in a CGI environment using L<HTTP::Request::AsCGI>, returns an
L<HTTP::Response>.

C<$coderef> is passed the Controller instance, and C<$c>.

The CGI environment is set up based on C<$c>.

The environment variables to pass on are taken from the configuration for your
Controller, see L</SYNOPSIS> for an example. If you don't supply a list of
environment variables to pass, the whole of %ENV is used (with exceptions listed
in L</FILTERED ENVIRONMENT>.

Used by L</cgi_to_response>, which is probably what you want to use as well.

=head1 FILTERED ENVIRONMENT

=head1 DIRECT SOCKET/NPH SCRIPTS

This currently won't work:

    #!/usr/bin/perl

    use CGI ':standard';

    $| = 1;

    print header;

    for (0..1000) {
        print $_, br, "\n";
        sleep 1;
    }

because the coderef is executed synchronously with C<STDOUT> pointing to a temp
file.
