PUB/SUB example has compilation errors
- using send and recv should be changed to send_string and recv_string
- The scenario of having multiple pubs/subs at the same time should be covered explicitly, I recommend.
Could you add a rst file about dealer router?
I found there are code for dealer router, but lack rst
Devices Section in Tutorial missing deprecated tag and new examples
http://learning-0mq-with-pyzmq.readthedocs.io/en/latest/pyzmq/devices/devices.html
It should be noted that using devices is deprecated since zmq version 3.2.
In light of this, the examples would need to be updated as well.
issue with server-client example
@ashishrv thanks for this documentation.
I was trying to run the client-server example, but after I run the two scripts pairserver.py and pairclient.py I can't see the messages printed in the shell. Nothing is printed. The scripts are:
pairserver.py
import zmq
import random
import sys
import time
port = "5556"
if len(sys.argv) > 1:
port = sys.argv[1]
int(port)
context = zmq.Context()
socket = context.socket(zmq.PAIR)
socket.bind("tcp://*:%s" % port)
while True:
socket.send_string("Server message to client3")
msg = socket.recv()
print(msg)
time.sleep(1)
pairclient.py
import zmq
import random
import sys
import time
port = "5556"
if len(sys.argv) > 1:
port = sys.argv[1]
int(port)
context = zmq.Context()
socket = context.socket(zmq.PAIR)
socket.connect("tcp://localhost:%s" % port)
while True:
msg = socket.recv()
print(msg)
socket.send_string("client message to server1")
socket.send_string("client message to server2")
time.sleep(1)
My python and pyzmq versions are:
Python 3.6.1 (default, Apr 4 2017, 09:40:21)
[GCC 4.2.1 Compatible Apple LLVM 8.1.0 (clang-802.0.38)] on darwin
>>> import zmq
>>> zmq.__version__
'16.0.2'
Name issue in patterns/pushpull.rst
under "consumer.py" it starts the sentence with "Producers are created with ZMQ.PULL" where it should start with "Consumers".
Pub/Sub is written incorrectly in scenario 2 image
https://github.com/ashishrv/pyzmqnotes/blob/master/source/pyzmq/patterns/pubsub.rst
Change the scenario2 image, a subscriber socket cannot send data to the publisher socket.
