Serv-O-Lux

It can also be used for writing different Ruby services or applications.

Features:

• Servolux::Threaded - when included into a class, it gives an activity thread that will run some code at a regular interval. Provides methods to start and stop the thread, report on the running state, and join the thread to wait for it to complete.
• Servolux::Server - a template server class that handles the mundane work of creating / deleting a PID file, reporting running state, logging errors, starting the service, and gracefully shutting down the service.
• Servolux::Piper - an extension of the standard Ruby fork method that opens a pipe for communication between parent and child processes. Ruby objects are passed between parent and child allowing, for example, exceptions in the child process to be passed to the parent and raised there.
• Servolux::Daemon - a robust class for starting and stopping daemon processes.
• Servolux::Child - adds some much needed funtionality to child processes created via Ruby‘s IO#popen method. Specifically, a timeout thread is used to signal the child process to die if it does not exit in a given amount of time.
