NAME

Test::Valgrind::Command - Base class for Test::Valgrind commands.

VERSION

Version 1.19

DESCRIPTION

This class is the base for Test::Valgrind commands.

Commands gather information about the target of the analysis. They should also provide a default setup for generating suppressions.

METHODS

new

    my $tvc = Test::Valgrind::Command->new(
     command => $command,
     args    => \@args,
    );

Creates a new command object of type $command by requiring and redispatching the method call to the module named $command if it contains '::' or to Test::Valgrind::Command::$command otherwise. The class represented by $command must inherit this class.

The args key is used to initialize the "args" accessor.

new_trainer

Creates a new command object suitable for generating suppressions.

Defaults to return undef, which skips suppression generation.

args

    my @args = $tvc->args($session);

Returns the list of command-specific arguments that are to be passed to valgrind.

Defaults to return the contents of the args option.

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 %ENV for the child process by returning an Env::Sanctify object, hence the name.

Defaults to void.

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 undef to indicate that no special suppressions are needed.

This method must be implemented when subclassing.

check_suppressions_file

    my $supp_ok = $tvc->check_suppressions_file($file);

Returns a boolean indicating whether the suppressions contained in $file are compatible with the command.

Defaults to true.

filter

    my $filtered_report = $tvc->filter($session, $report);

The $session calls this method after receiving a report from the tool and before forwarding it to the action. You can either return a mangled $report (which does not need to be a clone of the original) or undef if you want the action to ignore it completely.

Defaults to the identity function.
