Thanks alot for the info. Using a mule, I have "hello world" with UDP
working as follows:
$ cat example.ini
[uwsgi]
plugins = python
socket = /tmp/app.sock
no-default-app = true
udp = true
mule = /<path>/app.py
show-config = true
vacuum = true
$ cat /<path>/app.py
import uwsgi
import socket
print('\n\n --- Using {} ---\n\n'.format(globals()['__file__']))
UDP_IP = '127.0.0.1'
UDP_PORT = 5000
sock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
sock.bind((UDP_IP, UDP_PORT))
while True:
data, addr = sock.recvfrom(1024)
print('MULE #{0} received message: {1}'.format(uwsgi.mule_id(), data))
$ uwsgi --ini example.ini
...Thanks again!
