In my ongoing curiosity about websockets, I'm noticing a trend: The "hello world" of the websocket universe, at least at the moment, seems to be "echo" functionality. That is, the demonstrated application is typically, "I send something, I receive something." While aptly demonstrating that the protocol is functional, this example only actually demonstrates the same type of communication that the traditional request / response cycle enables. For example, the only demonstration (on the server side) that I can find of twisted.web.websockets is the following: import sys from twisted.python import

I'm working on writing a Python client for Direct Connect P2P networks. Essentially, it works by connecting to a central server, and responding to other users who are searching for files. Occasionally, another client will ask us to connect to them, and they might begin downloading a file from us. This is a direct connection to the other client, and doesn't go through the central server. What is the best way to handle these connections to other clients? I'm currently using one Twisted reactor to connect to the server, but is it better have multiple reactors, one per client, with each one

I'v learned twisted for somewhile and would like to do some network communication and local db operation as well.BTW, MySQL DB adopted, non-blocking required and perferred. Someone told me that sqlalchemy is just great. But as far as I have known from the Internet, the two may not work together perfectly(http://twistedmatrix.com/pipermail/twisted-python/2009-March/019359.html ). So I would like to know if anyone has this kind of experience(either successful or a failure is welcomed) to make both of them work together? And Could anyone tell why there is no way for them to work together? Thank

I would like to implement a TCP/IP network client application that sends requests to a Python SocketServer and expects responses in return. I have started out with the official Python SocketServer sample code : server.py: #!/usr/bin/env python # encoding: utf-8 import SocketServer class MyTCPHandler(SocketServer.StreamRequestHandler): def handle(self): request = self.rfile.readline().strip() print "RX [%s]: %s" % (self.client_address[0], request) response = self.processRequest(request) print "TX [%s]: %s" % (self.client_address[0], response) self.wfile.write(response) def processRequest(self,

Going through the twisted finger tutorial and seen the SO questions: Question-1 Question-2 However, I can't (yet) write a twisted program that can read & write from multiple serial ports, especially where the protocol involves reading single or multiple lines, and writing back to the device accordingly. What I am trying to do is open 2 pairs (i.e. total of 4) serial ports, for 2 modems. Communication with modems is using Hayes AT command set. While most of the command/response exchanges with modem is via the command-port, there are few diagnostic information that are available only via the

I am developing a networked application in Twisted, part of which consists of a web interface written in Django. I wish to use Twisted's WSGI server to host the web interface, and I've written a working "tap" plugin to allow me to use twistd . When running the server with the -n flag (don't daemonize) everything works fine, but when this flag is removed the server doesn't respond to requests at all, and there are no messages logged (though the server is still running). There is a bug on Twisted's Trac which seems to describe the problem exactly, and my plugin happens to be based on the code
