I'm still not sure what you mean by this. I can only assume you mean that your program will assume the existence of a PEP 3143 implementation (like the ‘python-daemon’ library), and your program will use its API. > I am not sure how to continue now though, is weird, I can swear I > searched for a while for libraries on how to daemonize correctly a > Python application and could not find anything quite like it. Note that, as described in PEP 3143, “daemonize a program” means nothing more than making the *current program* become a daemon process. It implies nothing special about external interaction with that process; having a service channel for controlling a separate process isn't part of becoming a daemon. > And now I know of python-daemon, python-ll-core (has a daemon > module) and daemon.py > <http://www.clapper.org/software/python/daemon/> > > Do you think I am going in the right direction? I'm still not clear on what your current direction is :-) As its champion, I think using PEP 3143 as a basis is the right direction, and have provided ‘python-daemon’ to help people get there. > The initial idea was to be able to build something I saw was not > available (or not fully available) but much needed.

You're asking, then, for what is commonly called a “service” process model. When implemented on Unix, this makes use of a daemon, but does something significantly more; PEP 3143 explicitly doesn't cover it, but is designed to be a good basis for it. What you want is someone to develop and champion a “service” PEP <URL:http://mail.python.org/pipermail/python-ideas/2009-January/002606.html> and implementation library. That person is not going to be me, but I encourage use of the daemon library API as a basis for implementing the Unix platform specifics of a service API. -- \ “One of the most important things you learn from the internet | `\ is that there is no ‘them’ out there.
