commandPort doesn't work in mayapy?

[Paul Molodowitch]

Just wanted to confirm that I'm not doing something wrong, or that there isn't something in our startup process that's making this fail... but is it True that the commandPort command doesn't work if run from inside of mayapy?  (Note that it DOES work from "maya -prompt")...

Here's the code I was using to test:

To start:

port = XXX

import pymel.core  # just to startup maya

import maya.cmds as cmds

cmds.commandPort(n=":%s" % port, sourceType='python')

print "socket opened on port %s" % port

To connect:

import socket

port = XXX

mayaSock = socket.socket()

mayaSock.settimeout(.5)

mayaSock.connect(('localhost', port))

try:

    mayaSock.send(r'print "hello from the outside world!\n";')

    mayaSock.send(r'polyCube();')

finally:

    mayaSock.close()

It looks like the different between maya -prompt and the mayapy standalone environment is that the event loop isn't started. mayapy does open the port and accept clients, but the client requests hang because they aren't being services.

Check this out. Start a request from your client, and then in your mayapy "server" process do this:

import maya.utils as mu

mu.processIdleEvents()

Your client should get a reply :-)

Looks like you will have to do the old pumpThread approach!

Huh, interesting...hadn't even thought of that as a possible solution.  In this case, I can use maya -prompt - just means have to write some MEL... but the manual idle-thread-processing approach could help in some cases where I wanted to have an on-idle callback in mayapy. Thanks!
