=head1 NAME
Test::Valgrind::Command - Base class for Test::Valgrind commands.
=head1 VERSION
Version 1.18
=cut
our $VERSION = '1.18';
=head1 DESCRIPTION
This class is the base for L<Test::Valgrind> commands.
Commands gather information about the target of the analysis.
They should also provide a default setup for generating suppressions.
=cut
use Test::Valgrind::Util;
use base qw<Test::Valgrind::Carp>;
=head1 METHODS
=head2 C<new>
my $tvc = Test::Valgrind::Command->new(
command => $command,
args => \@args,
);
Creates a new command object of type C<$command> by requiring and redispatching the method call to the module named C<$command> if it contains C<'::'> or to C<Test::Valgrind::Command::$command> otherwise.
The class represented by C<$command> must inherit this class.
The C<args> key is used to initialize the L</args> accessor.
=cut
sub new {
my $class = shift;
$class = ref($class) || $class;
my %args = @_;
my $cmd = delete $args{command};
if ($class eq __PACKAGE__ and defined $cmd) {
($cmd, my $msg) = Test::Valgrind::Util::validate_subclass($cmd);
$class->_croak($msg) unless defined $cmd;
return $cmd->new(%args);
}
my $args = delete $args{args};
$class->_croak('Invalid argument list') if $args and ref $args ne 'ARRAY';
bless {
args => $args,
}, $class;
}
=head2 C<new_trainer>
Creates a new command object suitable for generating suppressions.
Defaults to return C<undef>, which skips suppression generation.
=cut
sub new_trainer { }
=head2 C<args>
my @args = $tvc->args($session);
Returns the list of command-specific arguments that are to be passed to C<valgrind>.
Defaults to return the contents of the C<args> option.
=cut
sub args { @{$_[0]->{args} || []} }
=head2 C<env>
my $env = $tvc->env($session);
This event is called in scalar context before the command is ran, and the returned value goes out of scope when the analysis ends.
It's useful for e.g. setting up C<%ENV> for the child process by returning an L<Env::Sanctify> object, hence the name.
Defaults to void.
=cut
sub env { }
=head2 C<suppressions_tag>
my $tag = $tvc->suppressions_tag($session);
Returns a identifier that will be used to pick up the right suppressions for running the command, or C<undef> to indicate that no special suppressions are needed.
This method must be implemented when subclassing.
=cut
sub suppressions_tag;
=head2 C<check_suppressions_file>
my $supp_ok = $tvc->check_suppressions_file($file);
Returns a boolean indicating whether the suppressions contained in C<$file> are compatible with the command.
Defaults to true.
=cut
sub check_suppressions_file { 1 }
=head2 C<filter>
my $filtered_report = $tvc->filter($session, $report);
The C<$session> calls this method after receiving a report from the tool and before forwarding it to the action.
You can either return a mangled C<$report> (which does not need to be a clone of the original) or C<undef> if you want the action to ignore it completely.
Defaults to the identity function.
=cut
sub filter { $_[2] }
