A simple unix/linux daemon in Python

I've written a simple Python class for creating daemons on unix/linux systems. It was pieced together for various other examples, mostly corrections to various Python Cookbook articles and a couple of examples posted to the Python mailing lists. It has support for a pidfile to keep track of the process. I hope it's useful to someone.

  • (:identity req) is auth backend independent way to access user data
  • login and logout implementation depends on auth backend
  • :current-user doesn't imply that authentication is required, route should also have :auth-rules if authentication is required

AvReg: The Aviation RegEx Match Toolkit

General Tips

  • The PCRE flavour of RegEx is used here.
  • Append the i modifier to the end of the regex to make any pattern case-insensitive.
