NAME

Test::Valgrind::Session - Test::Valgrind session object.

VERSION

Version 1.14

DESCRIPTION

This class supervises the execution of the valgrind process. It also acts as a dispatcher between the different components.

METHODS

new

    my $tvs = Test::Valgrind::Session->new(
     search_dirs => \@search_dirs,
     valgrind    => $valgrind,  # One candidate
     valgrind    => \@valgrind, # Several candidates
     min_version => $min_version,
     no_def_supp => $no_def_supp,
     extra_supps => \@extra_supps,
    );

The package constructor, which takes several options :

  • All the directories from @search_dirs will have valgrind appended to create a list of candidates for the valgrind executable.

    Defaults to the current PATH environment variable.

  • If a simple scalar $valgrind is passed as the value to 'valgrind', it will be the only candidate. @search_dirs will then be ignored.

    If an array refernce \@valgrind is passed, its values will be prepended to the list of the candidates resulting from @search_dirs.

  • $min_version specifies the minimal valgrind version required. The constructor will croak if it's not able to find an adequate valgrind from the supplied candidates list and search path.

    Defaults to none.

  • If $no_def_supp is false, valgrind won't read the default suppression file associated with the tool and the command.

    Defaults to false.

  • $extra_supps is a reference to an array of optional suppression files that will be passed to valgrind.

    Defaults to none.

valgrind

    my $valgrind_path = $tvs->valgrind;

The path to the selected valgrind executable.

version

    my $valgrind_version = $tvs->version;

The version object associated to the selected valgrind.

no_def_supp

    my $no_def_supp = $tvs->no_def_supp;

Read-only accessor for the no_def_supp option.

extra_supps

    my @extra_supps = $tvs->extra_supps;

Read-only accessor for the extra_supps option.

run

    $tvs->run(
     action  => $action,
     tool    => $tool,
     command => $command,
    );

Runs the command $command through valgrind with the tool $tool, which will report to the action $action.

If the command is a Test::Valgrind::Command::Aggregate object, the action and the tool will be initialized once before running all the aggregated commands.

action

Read-only accessor for the action associated to the current run.

tool

Read-only accessor for the tool associated to the current run.

parser

Read-only accessor for the parser associated to the current tool.

command

Read-only accessor for the command associated to the current run.

do_suppressions

Forwards to ->action->do_suppressions.

parser_class

Calls ->tool->parser_class with the current session object as the unique argument.

report_class

Calls ->tool->report_class with the current session object as the unique argument.

def_supp_file

Returns an absolute path to the default suppression file associated to the current session.

undef will be returned as soon as any of ->command->suppressions_tag or ->tool->suppressions_tag are also undef. Otherwise, the file part of the name is builded by joining those two together, and the directory part is roughly File::HomeDir->my_home / .perl / Test-Valgrind / suppressions / $VERSION.

suppressions

    my @suppressions = $tvs->suppressions;

Returns the list of all the suppressions that will be passed to valgrind. Honors "no_def_supp" and "extra_supps".

start

    $tvs->start(
     action  => $action,
     tool    => $tool,
     command => $command,
    );

Starts the action and tool associated to the current run. It's automatically called at the beginning of "run".

abort

    $tvs->abort($msg);

Forwards to ->action->abort after unshifting the session object to the argument list.

report

    $tvs->report($report);

Forwards to ->action->report after unshifting the session object to the argument list.

finish

    $tvs->finish;

Finishes the action and tool associated to the current run. It's automatically called at the end of "run".

status

    my $status = $tvs->status;

Returns the status code of the last run of the session.
