NAME

Process::Delegatable - Run a Process::Storable object in an isolated perl

SYNOPSIS

# Background a finite length process
MyBigMemoryProcess->new( ... )->delegate('/opt/perl5005/perl');

DESCRIPTION

Process::Delegatable extends Process::Storable for the purpose of creating process objects that can be run inside other instances, or even other versions, of Perl, with the results of the object ending up in the object in the current perl instance as if it had been run here.

It adds a delegate method that launches a new copy of Perl, passing the Process to it using Process::Launcher, which will load and execute the process.

Please note that STDERR for the delegated process will be sent to /dev/null (or your equivalent) so there is no way to recieve any error output from the delegated process.

If you want to add logging or locks or some other feature to your delegated process, that is your responsibility, and you set them up in the prepare method.

METHODS

This method inherits all the normal methods from Process and in addition inherits the strict seperation of responsibility described in Process::Storable. You should be aware of both of these.

delegate

$process->delegate('/opt/perl5004/perl', '-MFoo::Bar');

The delegate method is provided by default, and will start another instance of another Perl (or if no arguments, the same Perl you are current running), although not necesarily with the same environment.

This allows you to use Process::Delegatable to run Processes that may need to allocate a large amount of memory, or need to be rigourously seperated from your main program.
