Bug 154038 – [Web IDL] interface objects should be Function objects

• Component: Bindings
• Status: RESOLVED FIXED

[Chris Dumez]

interface objects should be Function objects as per Web IDL:
- http://heycam.github.io/webidl/#interface-object
- http://heycam.github.io/webidl/#es-interfaces

So window.Event should be a Function object for e.g. but in WebKit it is a regular EventConstructor JSObject.
Firefox and Chrome match the specification.

This should also impact the "constructor" properties on prototype objects (e.g. Event.prototype.constructor) as their value in a reference to the interface object:

The style checker is correct that there’s no need for the argument name “global object” here.

> Source/WebCore/bindings/js/JSDOMConstructor.h:69
> +    static JSC::JSValue prototypeForStructure(JSC::VM&, const JSDOMGlobalObject& globalObject);

Ditto.

> Source/WebCore/bindings/js/JSDOMConstructor.h:115
> +    static JSC::JSValue prototypeForStructure(JSC::VM&, const JSDOMGlobalObject&);

Ditto.

Yes yes, this was just a "Work In Progress" patch that I will polish because marking as r?

No problem. Sometimes I review those by accident, sometimes intentionally. And sometimes people review mine. Sorry to waste your time replying to say something you were already planning to do!
