Browser Client Minification breaks Payload encoding/decoding #422
Description
The minified browser client breaks the encoding/decoding of Payloads in the browser when using XHR-Polling.
Here is the code to reproduce the bug:
var io = io.listen(8080);
io.enable('browser client minification'); // send minified client
io.set('transports', ['xhr-polling']);
io.sockets.on('connection', function(client){
client.on('message',function(msg){
//Send messages in succession to create a payload
client.send("Hello");
client.send("Hello!");
client.send("Hello!!");
client.send("Hello!!!");
client.send("Hello!!!!");
console.log(msg);
});
});Code on the client side:
<html>
<head>
<script src="http://localhost:11027/socket.io/socket.io.js"></script>
<script>
var socket = io.connect('http://localhost:11027');
socket.on('message', function (msg) {
document.getElementById('out').innerHTML = "<div>"+msg+"</div>" + document.getElementById('out').innerHTML;
});
function sendPayload() {
//Send messages in succession to create a payload
socket.send("Hello");
socket.send("Hello!");
socket.send("Hello!!");
socket.send("Hello!!!");
socket.send("Hello!!!!");
}
</script>
</head>
<body>
<button onClick="sendPayload();">Send Payload</button>
<div id="out"></div>
</body>
</html>Upon clicking "Send Payload" button on the web page, we expect 5 "hello" on the server console and 25 "hello" on the client output. Only one arrives on each side.
Removing the client minification string from server side fixes the problem.
Tested on socket.io version 0.7.7, installed using NPM.
