I'm trying to understand why we have both DOMWindow.webkitPostMessage
and DOMWindow.postMessage. I'm also trying to understand the
following comment in {JS,V8}DOMWindowCustom.cpp:
// This function has variable arguments and can be:
// Per current spec:
// postMessage(message, targetOrigin)
// postMessage(message, targetOrigin, {sequence of transferrables})
// Legacy non-standard implementations in webkit allowed:
// postMessage(message, {sequence of transferrables}, targetOrigin);
Specifically:
1) Can we remove webkitPostMessage? If we can't remove it now, is
there a time in the future at which we can remove it?
2) Can we adopt the behavior in the specification (and drop the
non-standard behavior)? If not, should we change the specification to
match our behavior?
Many thanks,
Adam
