Bug 102889 – WebSocket's MessageEvent.origin attribute is an empty string

• Component: WebCore Misc.
• Status: RESOLVED FIXED

[Chris Dumez]

According to specification (http://www.w3.org/TR/2012/CR-websockets-20120920/#feedback-from-the-protocol), we should "initialize [message] event's origin attribute to the Unicode serialization of the origin of the URL that was passed to the WebSocket object's constructor.". However, the current implementation returns an empty string for the event's origin.

Firefox seems to populate MessageEvent.origin according to the specification.

[Ian 'Hixie' Hickson]

Note that that URL is out of date. The current spec for Web Sockets is at:
   http://www.whatwg.org/specs/web-apps/current-work/multipage/network.html#feedback-from-the-protocol

Basically you never want to be referring to /TR/ versions of specs because they're always going to be out of date, because they're just snapshots of the current work.

In this particular case the requirement in question hasn't changed since the W3C made that snapshot, though.

What's this? Why can't you write a layout test using the current layout test framework?

Is this copyright correct? If this is a new file, the copyright would be intel's one.

Nit: messageToSend. WebKit uses camelCase variables even for constants.

Nit: You can use ShouldBeEqualToString("origin", "ws://localhost:8880")

Well, this is basically a simplified version of LayoutTests/http/tests/websocket/tests/hybi/send_wsh.py, which expects 1 message instead of 2. Since the original file was with Google copyright and the code is mostly the same, I kept the copyright.
Anyway, it does not really matter since you prefer I use existing infrastructure. I guess I'll use LayoutTests/http/tests/websocket/tests/hybi/send_wsh.py and send 2 messages.

Sounds nicer.

Looks OK.

Sorry for nit-picking. WebKit uses camelCase even for constants. So this could be firstMessageToSend and secondMessageToSend.

My bad. I'll fix it.
