UnixDatagramServer

[Jim Dennis]

 What part am I missing:

#!/usr/bin/env python2.2
import SocketServer, sys, os, socket

class USrvr(SocketServer.UnixDatagramServer): pass

class RHandler(SocketServer.BaseRequestHandler):
	num = 0 
	def handler(self):
		conn = self.request
		msg = [] 
		while 1:
			data = conn.recv(65535)
			if not data: break
			msg.append(data)
		self.messages.append(msg)
		self.wfile.write("%s\r\n" % self.num)
		self.num += 1


if __name__ == "__main__":

	try: 		os.unlink("/tmp/svr.socket")
	except: 	pass

	svr = USrvr("/tmp/svr.socket", RHandler)
	svr.serve_forever()


  I'm just trying to write a server (Unix domain sockets) that
  will be a blackhole for any text send to it and return an 
  incremented integer for every new connection/transaction.

  It runs, it seems to bind to the socket and accept connections 
  on it. (I can see the socket open in lsof and I can run the following
  commands from an interactive session:

from socket import *
a = socket(AF_UNIX, SOCK_DGRAM)
a.connect('/tmp/svr.socket')
a.send('tst')
3
a.recv(1)

   ... and it simply blocks.

   So, the question is how to I get a response back!
