zmq-recv.py: demo zmq receiver
2025-01-22, v1.0, ed <irc.rizon.net>, MIT-Licensed
https://github.com/9001/copyparty/blob/hovudstraum/bin/zmq-recv.py
basic zmq-server to receive events from copyparty; try one of
the below and then "send a message to serverlog" in the web-ui:
1) dumb fire-and-forget to any and all listeners;
run this script with "sub" and run copyparty with this:
--xm zmq:pub:tcp://*:5556
2) one lucky listener gets the message, blocks if no listeners:
run this script with "pull" and run copyparty with this:
--xm t3,zmq:push:tcp://*:5557
3) blocking syn/ack mode, client must ack each message;
run this script with "rep" and run copyparty with this:
--xm t3,zmq:req:tcp://localhost:5555
note: to conditionally block uploads based on message contents,
use rep_server to answer with "return 1" and run copyparty with
--xau t3,c,zmq:req:tcp://localhost:5555
