Stopping / Restarting upload of Big Data about b2share

[huwmorris]

Looking at this now. First task: when an upload is stopped, need to add an "Abort button". This would clear the chunks from the upload directory and remove the upload from the list.

So progress so far:

I've added an "Abort" button which only shows when the upload is stopped.

I'm trying to understand how to do anything with the button.

In simplestore-deposit.js are the following lines for dealing with the Start and Stop buttons.
$('#uploadfiles').click(function(e) {

$('#stopupload').click(function(d) {

Can anyone explain what 'd' and 'e' are in this context? How would I use this to call a python function which would clear the upload folder of the unwanted chunks?

I looked at the plupload documentation regarding chunks, and not having to upload a file in full if some of the chunks had already been uploaded. It says:
"In real world scenario you might want to store the chunks as separate files and combine them only after all of them are uploaded. This way you will be able to monitor the state of each chunk, request reuploading of the failed one, resume paused or failed uploads, etc.

There is an effort currently to build a convenient server-side handler class, that will handle it all. We are going to translate it into various server-side languages once it's ready. You can contribute if you want and are proficient in - some :)"

I couldn't find any other way to resume an upload, so if it is possible at all, it looks like it will have to be done the hard way.

The javascript code in question is a jQuery call to bind an event handler for any click event generated on the DOM elements with the id 'uploadfiles' and 'stopupload'. The e and d are parameters to the event handler function, and in this case are eventObject. More to be found at http://api.jquery.com/click/ and http://api.jquery.com/category/events/event-object/

There is a quite good system for uploading and sharing big data. They have an HTML5 upload with stop and resume feature and support for big files. I don't know whether their architecture is such that we could integrate the upload part from them: http://filesender.org

Just came across a jQuery File Upload widget that looks very similar to what we are using, but it supports resuming uploads by using chunked upload (like we do) and remembering uploaded bytes.
