Hi all,
I’d like something like this.
1. Maya is launched
2. A child process is launched; via e.g. subprocess.Popen
3. Upon exiting Maya, I’d like the child process to be killed
Ideally, it dies no matter how the parent died; be it normally or when
crashing. And ideally, it’d be cross-platform, and not rely on third-party
module(s), though that’s flexible.
Here’s what I’ve got at the moment.
import atexitimport subprocess
proc = subprocess.Popen(["python"], creationflags=subprocess.CREATE_NEW_CONSOLE)
def kill_child():
proc.kill()
atexit.register(kill_child)
This works standalone, and in Nuke, but not in Maya. It also doesn’t run
when a process is force-quitted/crashed.
So I went a little deeper, looking into OS-specific methods of doing it and
found this for Windows.

Which works, but relies on a library 25mb in size and quite elaborate
bundling requirements.
So then I came across this, which provides an example (at the end) that I
can’t quite wrap my head around, but seems to do what I want.

But, I can’t successfully adapt it; mainly because I simply don’t
understand it well enough. So I was hoping to get some pointers here,
either about how to adapt it to my scenario or suggest alternatives.
Any ideas?
Best,
Marcus
