Sharing a lock between gunicorn workers

Question

Is there a good way to share a multiprocessing Lock between gunicorn workers? I am trying to write a json API with Flask. Some of the API calls will interact a python class

Answer 1

I tried something, and it seems to work. I put preload_app = True in my gunicorn.conf and now the lock seems to be shared. I am still looking into exactly what's happening here but for now this is good enough, YMMV.
