No keyboard interrupt with PyZMQ 23.3.0.dev with PYthon 3.10 (windows)

It seems that the keyboard interrupt with python 3.10 and pyzmq 23.3.0 does not work anymore (windows).

I remember it working, but now it does not.

I used the example in https://zguide.zeromq.org/docs/chapter2/#Handling-Interrupt-Signals

import signal
import time
import zmq

context = zmq.Context()
socket = context.socket(zmq.REP)
socket.bind("tcp://*:5558")

# SIGINT will normally raise a KeyboardInterrupt, just like any other Python call
try:
    socket.recv()
except KeyboardInterrupt:
    print("W: interrupt received, stopping...")
finally:
    # clean up
    socket.close()
    context.term()

to no avail... I read this solution Stop pyzmq receiver by KeyboardInterrupt and indeed, signal.signal(signal.SIGINT, signal.SIG_DFL); works, but it does not execute the print statement, nor does it run the finally. Is this just me?

Solution

  • Actually, the best solution which is recommended in the documentation is to use green.

    import zmq.green as zmq
