Description Luke Zarko 2011-07-15 14:32:34 PDT
Typed arrays should become Transferable (ref. http://www.whatwg.org/specs/web-apps/current-work/complete/common-dom-interfaces.html#transferable-objects)-- that is, it should be possible to pass a typed array using postMessage such that control of the data is sent but the array's data is not copied.
Comment 1 Kenneth Russell 2011-11-03 11:29:25 PDT
After more discussion on public-webapps, only the ArrayBuffer type will be Transferable -- the typed array views will not be.

Note, though, that transfer of an ArrayBuffer necessitates side-effects on the views that refer to it, in order to cause their lengths to go to zero. However, this is essentially an implementation detail.

I suspect that this bug should be closed, and the work done under Issue 66578.

This is just the master bug for the feature. I suspect there will be no patches for it directly, and it will be resolved after all bugs that it depends on have been resolved.

I see. I wasn't sure which was the umbrella bug.

Done.
