Hello All, I realize this has been discussed at some length, but the posts I found keep leading me back to the start, so I thought I'd try..
I currently have some python "worker" scripts that make great use pyInotify, an event based "watch" manager. When files arrive in a "hot folder", the correct actions proceed. These scripts use a forever loop while "watching". Historically, the processes were managed at the command line, and killed when no longer needed. There are many instances now, and I wish to manage these processes via a web app. The Django workflow is: base URL mapped to a central monitoring view. The model keeps the instance name, pid and status. When action is desired (creating, starting, stopping) , function buttons in the template call jQuery click handlers which in turn call an Ajax request back to the appropriate view function. The view function performs the required action and returns the name, PID and custom status, and updates the database and returns any appropriate data back to jQuery for DOM insertion. The worker script subclasses multiprocessing.Process so that I can get the pid and use the control methods The problem is, since these worker scripts just sit and wait on the watched folders, the view never returns and the page appears to "hang". I've investigated subprocess.Popen, os.system(), various spawns, and external modules such as celery, supervisor and and even god. - The latter seem more suited for the queueing of "short-term" tasks. What I require seems simple, just run the requested process in the background. The terminal equivalent would be: "nohup <process> <args> &" and return control to the view. Any ideas on how to achieve this? Many thanks, -heath carlisle -- You received this message because you are subscribed to the Google Groups "Django users" group.
