thread question

[Rolf Wester]

Hi,

I have an application that starts a second thread, that receives
messages via a socket-server and puts that messages into a queue. The
main thread is polling that queue for new messages. My problem is that
the main thread takes to much of the time polling the empty queue while
the socket-server thread doesn't get enough time for receiving the
messages. Is it possible to force the main threat to sleep for a certain
amount of time or give the socket-server thread a higher priority?
Thanks in advance.

Kind regards

Rolf Wester

The good answer to your question:
Use a Queue.Queue instance as your queue. The queue instance has
methods that block if the queue is empty.

The direct answer to your question:
import time
time.sleep(5) # sleeps 5 seconds

Hi,

You can also use threading.Condi tion()
This is useful for having some max. time and additionaly being able t
start processing earlier again via cond.notify()
