the connection.handshake.address object is sometimes undefined

[thekiur]

io.sockets.on('connection', function(connection) {
  console.log(
    connection.handshake, // always present
    connection.handshake.address, // sometimes undefined
    connection.handshake.address.address // sometimes ReferenceError
  );
});

Thats pretty much it.
Im expecting connection.handshake.address.address to contain the IP address related to the client, but i sometimes randomly get a ReferenceError there, as connection.handshake.address seems to be undefined.

Node 0.8.x
Socket.IO latest

I have a same problem. And I use clusters + redis to sync sockets between processes. In app without it - this problem wasn't present.

I came up with a way to prevent:

var socket_ip = (socket.handshake != undefined && socket.handshake.address != undefined) ? socket.handshake.address.address : "IP_ERROR";

but it isn't a solution. sometimes my app has a dead-sockets in some processes, but in some other they aren't. So this is just a way to prevent crashing your app.

It may be because there are a lot "client not handshaken" so that's why socket.handshake is undefined?

hashi101, many thanks for this fix. Just giving it a try now, hopefully it will stop my app from crashing :-)

Worked like a charm. Thank you sir!
