Hi all, I have a python gui app that launches multiple applications using subprocess.Popen class and prints their output in the gui (using PIPEs, threads and wxPython). Everything works great but the problem is that some applications should run in the background (ie they don't close when the gui closes) so next time when you start the gui it will not have a handle on those processes that are still running and therefore won't be able to print their output.
So, I was wondering if there is any way to "preserve" the Popen object of those background processes and reload them when the gui is restarted? Ideally I would like to have the whole Popen object preserved but I could also get by with just the Popen.stdout file object. I can save the Popen.stdout.fileno() integer because that's what I use in os.read() to read the output anyway but that doesn't work. I have doubts that this could even conceptually work but I thought I'd try asking anyway. I don't have a full understanding of how processes and pipes work on the system level...
