=head1 NAME
Test::Valgrind::Action::Captor - Mock Test::Valgrind::Action for capturing output.
=head1 VERSION
Version 1.14
=cut
our $VERSION = '1.14';
=head1 DESCRIPTION
This class provides helpers for saving, redirecting and restoring filehandles.
It's not meant to be used directly as an action.
=cut
use File::Spec ();
use base qw<Test::Valgrind::Carp>;
=head1 METHODS
=head2 C<new>
Just a croaking stub to remind you not to use this class as a real action.
=cut
sub new { shift->_croak('This mock action isn\'t meant to be used directly') }
# Widely inspired from Capture::Tiny
sub _redirect_fh {
open $_[1], $_[2], $_[3]
or $_[0]->_croak('open(' . fileno($_[1]) . ", '$_[2]', '$_[3]'): $!");
}
sub _dup_fh {
my $fd = fileno $_[3];
open $_[1], $_[2] . '&' . $fd
or $_[0]->_croak('open(' . fileno($_[1]) . ", '$_[2]&', $fd): $!");
}
=head2 C<save_fh>
$tva->save_fh($from, $mode);
$tva->save_fh($from, $mode, $to);
Save the original filehandle C<$from> opened with mode C<$mode>, and redirect it to C<$to> if it's defined or to F</dev/null> otherwise.
=cut
sub save_fh {
my ($self, $from, $mode, $to) = @_;

$self->_redirect_fh($from, $mode, File::Spec->devnull);

}

push @{$self->{saves}}, [ $save, $mode, $from ];
if ($to and ref $to eq 'GLOB') {
$self->_dup_fh($from, $mode, $to);
} else {
$self->_redirect_fh($from, $mode, defined $to ? $to : File::Spec->devnull);
}
return;
}
=head2 C<restore_all_fh>
$tva->restore_all_fh;
Restore all the filehandles that were saved with L</save_fh> to their original state.
The redirections aren't closed.
=cut

my ($self) = @_;
