You obviously need some sort of protocol. Here is some code (taken
from a real project and modified a bit) which returns \r\n seperated
lines from a socket as they arrive which is a very simple (but
widespread) protocol.
self.rx_buf is set to "" in the initialisation
self.sock is the socket
def rx_line(self):
message = None
while 1:
pos = self.rx_buf.find("\r\n")
if pos >= 0:
message = self.rx_buf[:pos]
self.rx_buf = self.rx_buf[pos+2:]
break
try:
rx = self.sock.recv(4096)
except socket.error, e:
self.sock = None
raise ServerNetworkException(e)
if len(rx) == 0:
self.sock = None
raise ServerDisconnectedException()
self.rx_buf += rx
return message
Sorry I mis-understood your original post!
