Process::Delegatable - Run a Process::Storable object in an isolated perl
# Background a finite length process
MyBigMemoryProcess->new( ... )->delegate('/opt/perl5005/perl');
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.
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.
$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.
