Thanks, Massimo. I'm using web2py as an interface to an industrial process controller. The default rocket server and sqlite3 db are fine for this app as it will never be serving pages to more than 2 or 3 clients at time (usually just one via localhost). The process I want to label needs to be the same one your startup message advises to kill with SIGTERM. That's the one that runs the model and controller on each page request, right?
Your suggestion to paste web2py.py into the body of my top-level process is intriguing. Looking at the code in web2py.py and considering that 1) my code will never run as a frozen exe on Windows and 2) I can ignore at least for now the coverage import, it appears I could reduce it to: import os import sys path = os.path.dirname(os.path.abspath(__file__)) # alter to make sure we point toplevel web2py dir. os.chdir(path) sys.path = [path] + [p for p in sys.path if not p == path] # important that this import is after the os.chdir import gluon.widget # Start Web2py (without cron service) ! #TODO fix up sys.args to match my use case #TODO call setproctitle here gluon.widget.start(cron=True) So if I wrap all the above in a function, would I be able to launch it successfully with multiprocessing.Process? That would be a real help as I could then dispense with a top-level shell script that's now launching web2py separately from my other processes. And would the setproctitle() call give the desired result or would I need to push that down into gluon.widget? Thanks!
