Socket.IO issue with control chars

Question

I am implementing an application that uses websockets and a console accessed via Telnet. There is a communication between the connection established via websockets and the console. I am experiencing a weird issue:

• If I send a string constant to an established socket when something is entered in the console it works ok.
• If I send a string received from the console scope It seems to open a new socket (not sure) because in the debug log I see it and in the browser side (websockets) it alerts me of a new connection.
• If I send a local string (instead of the one received from the other scope) it's sent correctly. (commented line: client.send(message) )

I share here the nodeJS code, take into account that this is now a test app so it's assumed only one socket and websockets connection:

// Sample based on: http://elegantcode.com/2011/05/04/taking-baby-steps-with-node-js-websockets/ // Changed for sockets.io 6.x => 7.x   var events = require('events'); var eventEmitter = new events.EventEmitter();  var http = require('http'); var socketIO = require('socket.io'); var static = require('node-static');  var port = 2000;  var clientFiles = new static.Server('./client');  var httpServer = http.createServer(     function(request, response) {         request.addListener('end', function() {              clientFiles.serve(request, response);        });     })  httpServer.listen(port); console.log("Server running at port: " + port);  var io = require('socket.io').listen(httpServer);  var webSocket = io.sockets;  webSocket.on('connection', function(client) {     client.send('Please enter a user name ...');     var userName;      eventEmitter.on('someOccurence', function(message) {         console.log("Received: " + message);         client.send('Line Received');         var s = 'popo';         client.send(s);         //client.send(message);     });       client.on('message', function(message) {         console.log(message);          if(!userName) {             userName = message;             client.broadcast.send(message + ' has entered the zone.');             return;         }          var broadcastMessage = userName + ': ' + message;         client.broadcast.send(broadcastMessage);         client.send("Repeated here: " + message);     });      client.on('disconnect', function() {         var broadcastMessage = userName + ' has left the zone.';         client.broadcast.send(broadcastMessage);     }); });   var lines = require('lines-adapter'); var net = require('net');  var server = net.createServer(function (socket) {     socket.write("Welcome to the Server\r\n");      lines(socket, 'utf8')     .on("data",         function(line) {             console.log("Line received: " + line);             eventEmitter.emit('someOccurence', line);         }     )     .end("end",         function() {             console.log("End of Stream");         }     ); });  server.listen(1337, "127.0.0.1");

UPDATE: I just tested with socket.io 0.8.6 and nodeJS 0.4.12 without this issue. I will keep this question here for future reference.

Answer 1

Fixed with socket.io v0.8.6. This q should be answered/closed.
