Hi Chris,
Bit hard to comment on the actual code, as it was in attachments, but the
important bit is here:
class Handler(SocketServer.BaseRequestHandler): #the handler
'''A handler which calls %s in the handle method.'''%handle_func
def handle(self): #the handle method
self.data = self.request.recv(1024) #the data
self.client = self.request #the client
handle_func(self) #call the handle method giving self
(I did a bit of reformatting, since I had to try the code myself, because I
didn't spot the error immediately.)
In essence, your server accepts the client connection, then proceeds to the
handle function, where it performs the necessary actions. It will *not* call
the handle function for each set of data it receives, it just stays there.
So you'll need a while loop in your handle function that keeps on processing
the client data, until there is not client data anymore (EOF or similar), then
return.
