mem leak ?

gistfile1.js

require('webkit-devtools-agent')

var
  http = require('http'),
  done = 0, todo = 30, doing = todo;

console.log('We should do '+ todo +' requests');

http.createServer(function (req, res) {
  res.writeHead(200, {'Content-Type': 'text/plain'});
  res.end('Hello World\n');
}).listen(3000, '127.0.0.1', getall);

// show memused and progress while running
setInterval(status, 5000);status();

function getall() {
  // creates a big buffer
  var megabig = new Big();

  // this should not trigger a memory leak but it does when using http.get
  function cb() {
    done+=1;
    return megabig;
  }

  while(doing--) {
    http.get({
      hostname: 'localhost',
      pathname: '/index.html?' + Math.random(),
      port: 3000,
      protocol: 'http:'
    }, cb);
  }
}

function Big() {
  this.yo = (new Buffer(1 * 1024 * 1024 * 100)).toString();
}

function status() {
  var
    mem = process.memoryUsage(),
    rss = (mem.rss/1024/1024).toFixed(),
    heapUsed = (mem.heapUsed/1024/1024).toFixed(),
    heapTotal = (mem.heapTotal/1024/1024).toFixed();

  console.log('rss: %dMB, heapUsed: %dMB, heapTotal: %dMB',rss, heapUsed, heapTotal);
  console.log('Done: '+ done +'/'+ todo);
  if (done === todo) {
    console.log('All requests done, memory should be collected')
  }
}

url & request modules seem to be unused, you should remove them

thx :)

http.request + req.end() needs less memory ! see : https://gist.github.com/2503608
(but memory leak is still there ...)
