question about python and sockets.. as the accept line() exacutes program hangs

xskycamefalling · 02-10-2010, 05:00 PM

ok so my question here is i wrote a simple chat type like thing to just see if what i read was working.. anyway

on the server side once it hits the

Code:

clientsocket, address = serversocket.accept()

pythonwin dosent respond untill i actually connect with the client
its a TCP based socket SOCK_STREAM

it doest the same thing when i do it under linux as well

so i guess im just wonder is it because im using TCP that its hanging? is it waiting for the connection? could this be eliminated using udp or is their a way that i could check if a client was trying to connect and if not exacute more commands and then come back to check again after so long like a compare a count variable in a loop or something
any help is much appreciated

You need to make the socket nonblocking. After you have created it, use

Code:

socket.setblocking(0)

And it should work better. Then you need to select() or any other method to find out when the client actually connects.
