Hey all,
This is the relevant part of my server:
def serve():
server = grpc.server(futures.ThreadPoolExecutor(max_workers=10))
users_service.add_UsersServicer_to_server(UsersService(), server)
res = server.add_insecure_port('127.0.0.1:50051')
server.start()
try:
while True:
time.sleep(_ONE_DAY_IN_SECONDS)
except KeyboardInterrupt:
server.stop(0)
On OS X, by mistake i started the server twice in different terminal
sessions and I expected it to fail the second time (address already bound,
etc). However, it didn't error out and this is what I see via lsof:
$ sudo lsof -iTCP:50051
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
Python 12120 amit 4u IPv6 0xffbffb1742aa0f0f 0t0 TCP
localhost:50051 (LISTEN)
Python 12157 amit 4u IPv6 0xffbffb1742aa144f 0t0 TCP
localhost:50051 (LISTEN)
Curiously enough, they both have the same FD.
(I verified it with a Flask application to see if it was something Python
specific, and i do see the expected error message when I try to start a
second instance of the same)
Thanks for any hints in advance.
Best Wishes,
Amit.
