I have a Flask application that uses a messaging library that is NOT process safe (multiple processes using the same pointer results in a panic: not fork-reentrant error)
I've noticed that there is a large difference between the options on this flask page: http://flask.pocoo.org/docs/1.0/deploying/wsgi-standalone/
Gevent works for my application. I never get into a panic.
UWSGI does not work for my application; it panics as soon as the second request comes in.
Is the following understanding correct then?
Gevent works using greenlet which is a coutourtine library, but it executes all within a single process.
UWSGI launches a new process for each incoming request, so upon the second request, a process is launched and the shared memory is access which causes the panic.
I guess my high level question is what the exact difference between uwsgi and gevent.pywsgi is>?
python flask gevent
