846135 - Wrong upload progress if the file is large

Status: RESOLVED INCOMPLETE

(Core :: DOM: Core & HTML, defect)

Description

[Dongwei]

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_6_8) AppleWebKit/537.22 (KHTML, like Gecko) Chrome/25.0.1364.99 Safari/537.22

Steps to reproduce:

Upload a big file over 800M, and the network is slow.


Actual results:

I see the progress bar shows the percentage is larger than 100%. And I debug to find evt.loaded gives the wrong percentage.


Expected results:

By any means, evt.loaded should give the right percentage.

Dongwei, would you have a testcase?

Comment 2

[Dongwei]

Mounir,  if you have a testcase on upload's "progress“ event, e.g.

xhr.upload.addEventListener("progress", uploadProgress, false);

function uploadProgress(evt) {
  if (evt.lengthComputable) {
    var percentComplete = Math.round(evt.loaded * 100 / evt.total);
    document.getElementById('progressNumber').innerHTML = percentComplete.toString() + '%';
  }
  else {
    document.getElementById('progressNumber').innerHTML = 'unable to compute';
  }
}

If the file to upload is big, my file is about 800M, and my bandwidth is about 20k/s. almost every time, I can see percentComplete is > 100%. And when it became to 200%, it showed upload failed.

Is this a dup of the one where .total tells the compressed size and .loaded the uncompressed?

By Firebug, I can see if the upload takes a long time, the request will be aborted, and the progress will became 100%. But immediately, it will restart to upload.. I do not know Firefox has retry mechanism or it relates to this bug.

Olli, is there a bug number for the .total issue ? I want to read and confirm if this is the same issue we are seeing in our production environment.
