Can't upload file to s3 when file size is 0

[clues]

When file size is 0,i can't upload file to s3,Use wireshark tools i found sdk not send http request to s3.
my code:
s3obj.upload({Body: body}).send(cb);

i modify two code in l lib/s3/managed_upload.js file and it't work:

/**

• @api private
  */
  fillStream: function fillStream() {
  var self = this;
  if (self.activeParts >= self.queueSize) return;

  var buf = self.body.read(self.partSize - self.partBuffer.length) ||
  self.body.read();
  if (buf) {
  self.partBuffer = AWS.util.Buffer.concat([self.partBuffer, buf]);
  self.totalChunkedBytes += buf.length;
  }

  if (self.partBuffer.length >= self.partSize) {
  self.nextChunk(self.partBuffer.slice(0, self.partSize));
  self.partBuffer = self.partBuffer.slice(self.partSize);
  } else if (self.isDoneChunking) {
  self.totalBytes = self.totalChunkedBytes;
  if (self.partBuffer.length >= 0) { // change self.partBuffer.length > 0 to self.partBuffer.length >= 0
  self.numParts++;
  self.nextChunk(self.partBuffer);
  }
  self.partBuffer = new AWS.util.Buffer(0);
  }

  self.body.read(0);
  }

  /**

• @api private
  */
  adjustTotalBytes: function adjustTotalBytes() {
  var self = this;
  try { // try to get totalBytes
  self.totalBytes = byteLength(self.body);
  } catch (e) { }

  // try to adjust partSize if we know payload length
  if (self.totalBytes) {
  var newPartSize = Math.ceil(self.totalBytes / self.maxTotalParts);
  if (newPartSize > self.partSize) self.partSize = newPartSize;
  }else if(self.totalBytes ==0){ //When self.totalBytes is 0, it's not boolean false; so care of here
  self.totalBytes =0;
  }
  else {
  self.totalBytes = undefined;
  }
  }

Please update to github source files

It's hard to know what's changed here. Would you mind packaging this up as a pull request? That way you can also get credit for your work!

@lsegal :OK

Oh no, my code can upload empty file, but will lead to new problem: file size more than (4~5)mb seem will dead chunk and send large http request to s3.So i expect new solution.
