NAME
Test::Valgrind::Command - Base class for Test::Valgrind commands.
VERSION
Version 1.16
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.
