NAME

Doit::Fork - run code in another process

SYNOPSIS

    use Doit;
    use Doit::Log;
    sub run_test {
        my(undef, $arg) = @_;
        return "running in process $$ with arg $arg";
    }
    return 1 if caller;
    my $doit = Doit->init;
    $doit->add_component('fork');
    my $fork = $doit->do_fork;
    info $fork->call_with_runner('run_test', 'test argument');

DESCRIPTION

This component provides a function do_fork, which forks a new process and returns a new Doit runner (like "do_ssh_connect" in Doit or "do_sudo" in Doit. This process is capable of running subroutines (using call_with_runner or call), or any other core Doit function.

A possible use case is to have multiple separated processes, but with the ability (unlike with normal forked processes) to call subroutines in these processes with possibly complex arguments and return values.

Note that all communication is still synchronous.
