New submission from anon01 <swsfi...@sharklasers.com>:
When I run this code (on a UNIX system with temporary directory `/tmp/`): ``` from multiprocessing import connection import threading key=b"1" def run(): c=connection.Client("/tmp/xxx", authkey=key) c.send("data") l=connection.Listener("/tmp/xxx", authkey=key) threading.Thread(target=run).start() c=l.accept() print("receive", c.recv()) ``` it prints out "receive data" normally. However, in the special case that `key=b""` the doesn't print anything, and can only be interrupted with Ctrl+C. `key=None` doesn't have that issue. Note that this issue does happen when the client uses the key `b""` and the server uses the key `None`, but the program works normally if the reverse situation.
