Essentially, my question is, should ArrayBufferView *replace* ArrayBuffer in the existing constructor, or should it be an additional optional invocation parameter? 66728 2 zcorpan 2012-04-16 04:58:09 +0000 The XHR discussion ended up replacing ArrayBuffer with ArrayBufferView for send(). I think one argument is that authors may have a sliced view and then pass .buffer and not realize that it contains the whole data, which results in buggy code. If we support only ArrayBufferView, we prevent the buggy case from happening (at the cost of making authors create a view). 67374 3 arun 2012-05-07 05:06:53 +0000 Marking this fixed. http://dev.w3.org/2006/webapi/FileAPI/#dfn-Blob
