Hello I am writing an addon to ease the addon development with Emacs(and other editors... when it works well) and Blender. The goal isto make Blender reload the addon on saving.
I use ipv4, TCP sockets for IPC. I had to fork a process from blender for the socket communication, because I could not close the socket any other way, the reason: I do not know a way to make a handler for closing in Blender (however it would be very handy).
With the child process I worked around it, when Blender (parent) terminates, the init process (pid = 1) will "adopt" the child, which can be detected with os.getppid(). It works now, but It has a side effect: Blender can not be closed from the GUI, but with SIGTERM. It is funny becuse blender is the most badass software when it comes to closing :) .
My questions: 1. Why is this hapenning? 2. Are there any more suitable ways for IPC or socket closing?
I use 2.76b offical build on Gentoo Linux(kernel version 3.18.12)
I am not an expert programmer so maybe I miss something important
