[Twisted-Python] Twisted hangs when using pyapns

[Ni Wesley]

I got the point.
server.py:
def write(self, notifications):
    "Connect to the APNS service and send notifications"
    if True: #not self.factory:
      log.msg('APNSService write (connecting)')
      with open('/tmp/wniapns.log','a') as f:
          f.write("#"*20+"\n")
          f.write("apns server1\n")
          f.write("#"*20+"\n")
      server, port = ((APNS_SERVER_SANDBOX_HOSTNAME
                      if self.environment == 'sandbox'
                      else APNS_SERVER_HOSTNAME), APNS_SERVER_PORT)
      self.factory = self.clientProtocolFactory()
      context = self.getContextFactory()
      reactor.connectSSL(server, port, self.factory, context)

    client = self.factory.clientProtocol
   * if client:*
      with open('/tmp/wniapns.log','a') as f:
          f.write("#"*20+"\n")
          f.write("apns server2\n")
          f.write("#"*20+"\n")
      return client.sendMessage(notifications)
    else:
Problem is for twice push to one device, client is not None the second
time, code goes here and error then.

BTW, what I wanna ask is where is the default log file? I didn't see any
exception raised.

I haven't used pyapns and twisted before, I see twisted has lines like
log.msg("xx"), where is the default log file?

Thanks.
Wesley
