In the attached multiprocessing.connection simple client script, the poll() method is always returning false. If I force the temp variable to 1, the recv()method happily gets the incoming data. I had hoped to use the poll() method to implement a timeout error, to avoid the blocking nature of the client. |

Thanks for the report.
It seems to only affect Windows, and only when using sockets rather than pipes.
Till this is fixed you could use
temp = bool(multiprocessing.connection.wait([cl], 1))
instead of
temp = cl.poll(1)
As I mentioned on the other issue, I would not advise use of Listener() and Client() without using authentication -- you are probably better off using raw sockets and select().

Hi Rchard: Thanks very much. The wait() method works fine. Regards, John Brearley 613-259-5622 (H) |
