NAME
   Mojolicious::Plugin::OnFork - Do Something Whenever a Worker Starts

VERSION
   Version 0.006

SYNOPSIS
     # Mojolicious
     $self->plugin('OnFork' => sub { srand })
       if $ENV{HYPNOTOAD_APP};

     # Mojolicious::Lite
     plugin OnFork => sub { srand }
       if $ENV{HYPNOTOAD_APP};

DESCRIPTION
   Mojolicious::Plugin::OnFork is a plugin to easily define code, that is
   executed whenever a new worker process of the web server forks.

   All this plugin actually does is

     Mojo::IOLoop->timer(0 => $code)

   The motivation for this plugin was, that hypnotoad does not guarantee
   to call srand() after a fork(), so worker processes might all get the
   same sequence of "random" numbers from rand().

   Starting with Mojolicious 5.76 "srand" is actually called after a
   fork, but this fact is not officially documented and according to the
   author can be removed in the future without any previous notice.

   As a consequence depending on the Mojolicious version and for this
   use case "srand" might be called twice after a worker starts.

METHODS
   Mojolicious::Plugin::OnFork inherits all methods from
   Mojolicious::Plugin and implements the following new ones.

 "register"
   Register plugin hooks in Mojolicious application.
