Bug 30417 – Need to properly disable applicationCache at runtime

• Component: WebCore JavaScript
• Status: RESOLVED FIXED

[Andrew Wilson]

This if statement should evaluate to false if applicationCache is disabled at
runtime:

if ('applicationCache' in window)

You can look at https://bugs.webkit.org/show_bug.cgi?id=30240 for an example of
how this was done for window.Audio(). We probably need to move this setting out
of WebCore::Settings and into a global static so it's easily accessible from
the V8 bindings.

There is a TAB in the changelog that needs to be removed.

Nice start, but this is incomplete as discussed.

I think you have not really changed the visible functionality so no new tests.

> Index: WebCore/bindings/v8/custom/V8CustomBinding.h
>  #if ENABLE(OFFLINE_WEB_APPLICATIONS)
> +	DECLARE_ACCESSOR_RUNTIME_ENABLER(DOMApplicationCache);

Another TAB to remove.

I can fix this on landing.
