TypeError: Object has no method packet

[nicholasrq]

Hello. Faced with problem with global emitting events.
That's the server-side error btw instead of #489.

Cases when error occur

nsp = io.of('/namespace');
nsp.emit('hello', 'there');

io.emit('hello', 'there');

io.sockets.emit('hello', 'there');

var needed_namespace = '/my_namespace';
io.nsps[needed_namespace].emit('hello', 'there');

In every case i have the following error:

TypeError: Object function (key) {
  if (!this[key]) {
    return this[key] = 1;
  } else {
    return this[key] += 1;
  }
} has no method 'packet'

Actual code where error occur (it compiled from CoffeeScript, sorry for readability):

  deliver: function(message, channel, namespace, socket) {
    var err;
    socket = this.get_namespace(namespace, socket);
    message = this.prepage_message(message);
    try {
      if (channel != null) {
        //error occur here (line 125:28 from error stack)
        return socket.emit(channel, message);
      }
      //also error will be here when 'channel' not passed to '.deliver()'
      return socket.emit(message);
    } catch (_error) {
      err = _error;
      return console.warn('Something may be wrong: ' + err.stack);
    }
  },
  get_namespace: function(ns, socket) {
    var namespace, _ref;
    if (socket != null) {
      return socket;
    }
    namespace = null;
    if ((namespace = this.namespaces[ns]) != null) {
      return namespace;
    } else if ((namespace = (_ref = this.io.nsps) != null ? _ref[namespace] : void 0) != null) {
      return this.namespaces[ns] = namespace;
    } else {
      return this.create_namespace(ns);
    }
  },
  create_namespace: function(ns) {
    var socket;
    if (ns == null) {
      ns = '/';
    }
    socket = this.io;
    if (ns !== '/') {
      socket = socket.of(ns);
    }
    this.namespaces[ns] = socket;
    return socket;
  }

Any solutions? Or may be i doing it wrong?
Btw two of these cases are listed in official docs on http://socket.io.

UPD:

One more stack-trace with Socket.IO debug out:

  socket.io-parser encoding packet {"type":2,"data":["hello","world"],"nsp":"/"} +0ms
  socket.io-parser encoded {"type":2,"data":["hello","world"],"nsp":"/"} as 2["hello","world"] +0ms

        if (socket) socket.packet(encodedPackets, true, flags.volatile);
                           ^

  } has no method 'packet'

Problem solved. It was modified prototype of Object. I think it's really good practice to use hasOwnProperty in for ... in loops like this one:

It's part of socket.io-adapter/index.js

      for (var id in self.sids) {
        if (~except.indexOf(id)) continue;
        socket = self.nsp.connected[id];
        if (socket) socket.packet(encodedPackets, true, flags.volatile);
      }

Otherwise somebody like me may have problems with such code when using libraries like Sugar.js.
