[webkit-dev] starting implementation of postMessage tranferables
*Summary*: Implementing postMessage with transferable support as webkitPostMessage. *Details*: *Spec*: http://www.whatwg.org/specs/web-apps/current-work/multipage/comms.html#posting-messages This describes window.postMessage and the same is true for Message Ports and Worker Context. It doesn't mention Array Buffers but that will be mentioned soon and is in the spec that talks about Array Buffers. Tracking bug: https://bugs.webkit.org/show_bug.cgi?id=64629 *Plan*: 1. Add webkitPostMessage to all of these places to isolate us from possible spec changes. It will have the same functionality as postMessage. 2. Add the ability to transfer Message Ports. 3. Add the ability to transfer Array Buffers. We don't plan to put ifdef's around this as we'll do an implementation for all ports and js engines and each patch is complete by itself. (Even when using webkitPostMessage, one has to be careful to verify that the items being transfered may be transfered. After step 1, the answer is no to everything.) I didn't send this earlier because we were doing this in postMessage and it was in the spec but it would have been good to send out the email even then. dave ___ webkit-dev mailing list webkit-dev@lists.webkit.org http://lists.webkit.org/mailman/listinfo.cgi/webkit-dev

I think we should wait and see -- spec changes have caused issues for us in the past (eg. localStorage :-/ ) There is not any substantive harm in prefixing, whereas there can be real problems down the road if we don't prefix. --Oliver -- Ian Hickson U+1047E)\._.,--,'``.fL http://ln.hixie.ch/ U+263A/, _.. \ _\ ;`._ ,.
