=head1 NAME
Test::Valgrind::Tool - Base class for Test::Valgrind tools.
=head1 VERSION
Version 1.14
=cut
our $VERSION = '1.14';
=head1 DESCRIPTION
This class is the base for L<Test::Valgrind> tools.
They wrap around C<valgrind> tools by parsing its output and sending reports to the parent session whenever an error occurs.
They are expected to function both in suppressions generation and in analysis mode.
=cut
use base qw<Test::Valgrind::Component Test::Valgrind::Carp>;
=head1 METHODS
=head2 C<requires_version>
my $required_version = $tvt->requires_version;
The minimum C<valgrind> version needed to run this tool.
Defaults to C<3.1.0>.
=cut
sub requires_version { '3.1.0' }
=head2 C<new>
my $tvt = Test::Valgrind::Tool->new(tool => $tool);
Creates a new tool object of type C<$tool> by requiring and redispatching the method call to the module named C<$tool> if it contains C<'::'> or to C<Test::Valgrind::Tool::$tool> otherwise.
The class represented by C<$tool> must inherit this class.
=cut
sub new {
my $class = shift;
$class = ref($class) || $class;
my %args = @_;
if ($class eq __PACKAGE__) {
my $tool = delete $args{tool} || 'memcheck';
$tool =~ s/[^\w:]//g;
$tool = __PACKAGE__ . "::$tool" if $tool !~ /::/;
$class->_croak("Couldn't load tool $tool: $@") unless eval "require $tool; 1";
return $tool->new(%args);
}
$class->SUPER::new(@_);
}
=head2 C<new_trainer>
my $tvt_train = Test::Valgrind::Tool->new_trainer;
Creates a new tool object suitable for generating suppressions.
Defaults to return C<undef>, which skips suppression generation.
=cut
sub new_trainer { }
=head2 C<parser_class>
my $parser_class = $tvt->parser_class($session);
Returns the class from which the parser for this tool output will be instanciated.
This method must be implemented when subclassing.
=cut
sub parser_class;
=head2 C<report_class>
my $report_class = $tvt->report_class($session);
Returns the class in which suppression reports generated by this tool will be blessed.
This method must be implemented when subclassing.
=cut
sub report_class;
=head2 C<args>
my @args = $tvt->args($session);
Returns the list of tool-specific arguments that are to be passed to C<valgrind>.
All the suppression arguments are already handled by the session.
Defaults to the empty list.
=cut
sub args { }
=head2 C<suppressions_tag>
my $tag = $tvt->suppressions_tag($session);
Returns a identifier that will be used to pick up the right suppressions for running the tool, or C<undef> to indicate that no special suppressions are needed.
This method must be implemented when subclassing.
=cut
sub suppressions_tag;
=head2 C<start>
$tvt->start($session);
Called when the C<$session> starts.
Defaults to set L<Test::Valgrind::Component/started>.
=head2 C<filter>
my $filtered_report = $tvt->filter($session, $report);
The C<$session> calls this method after receiving a report from the parser and before letting the command filter it.
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] }
=head2 C<finish>
$tvt->finish($session);
Called when the C<$session> finishes.
Defaults to clear L<Test::Valgrind::Component/started>.
