Concrete5: File Chunking Uploader

[joe-meyer]

I think we should evaluate options for doing chunked file uploads. I'm not sure if it's feasible that this could be another service provider or not or if it just gets baked in but I think there are several advantages to doing it:

• High latency / Low Bandwidth users will experience less upload time in the event of a time out or network error as they would only have to re-upload the chunks that were missing
• No more having to worry about max_post_size or max_upload_size, we chunk at 2mb, and go from there

I wouldn't mind seeing http://www.plupload.com/examples/core implemented. I think it would be super straightforward to do and can run HTML5, silverlight, or flash based if it needs to fallback for browser support.

Thoughts?

Newest versions of Dropzone seems to support uploads in chunks (reference).
If #6417 gets merged, we can think of a solution for this.

Sorry, missed the link to the reference. Here it is: http://www.dropzonejs.com/#config-chunking

Just wanted to see about reviving this feature. We've got a current enough version of dropzone and having this would virtually eliminate uploading errors related to file size and prevent otherwise unnecessary raising of limits of the maximum post and upload limits. Even if we implement a separate "Large File Upload" piece for handling that specific scenario I think it would be worthwhile if it's difficult to revamp existing handling.

It's really interesting – I don't have much experience with this approach at all, but we'd certainly look to support it in the file manager if we could turn it on easily.
