NAME

PPerl - Make perl scripts persistent in memory

SYNOPSIS

$ pperl foo.pl

DESCRIPTION

This program turns ordinary perl scripts into long running daemons, making subsequent executions extremely fast. It forks several processes for each script, allowing many proceses to call the script at once.

It works a lot like SpeedyCGI, but is written a little differently. I didn't use the SpeedyCGI codebase, because I couldn't get it to compile, and needed something ASAP.

The easiest way to use this is to change your shebang line from:

#!/usr/bin/perl -w

To use pperl instead:

#!/usr/bin/pperl -w

WARNINGS

Like other persistent environments, this one has problems with things like BEGIN blocks, global variables, etc. So beware, and try checking the mod_perl guide at http://perl.apache.org/guide/ for lots of information that applies to many persistent perl environments.

Parameters

$ pperl <perl params> -- <pperl params> scriptname <script params>

The perl params are sent to the perl binary the first time it is started up. See perlrun for details.

The pperl params control how pperl works (none actually implemented yet).

The script params are passed to the script on every invocation. The script also gets any current environment variables, and everything on STDIN.

BUGS

The process does not reload when the script or modules change.
