Bug 22355 – Systematize code for replacing global constructors

• Component: WebCore JavaScript
• Status: RESOLVED FIXED

[Alexey Proskuryakov]

JSDOMWindow implements global constructor replacement in setJSDOMWindowXXX functions; JSDOMWindowBase has special cases in put(), and JSWorkerContext is just broken.

Probably easiest to make all code match generated one; patch forthcoming.

Can we autogenerate this code?

How about a helper function for this idiom? I can't think of any good reason to write this out explicitly 8 times instead of using a function.

I like that these look as close as possible to JSDOMWindow auto-generated ones. Lately, I've spent considerable time digging through minor differences in how the same things are implemented, so I think that consistency is important here.

What we really need is to auto-generate these, and move them to DOMWindow from JSDOMWindowBase.
