A small change with lots of test progressions!  This is great, but r- because of a small unchecked pointer issue:

> Source/WebCore/Modules/fetch/DOMWindowFetch.cpp:42
>  void DOMWindowFetch::fetch(DOMWindow& window, FetchRequest* input, const Dictionary& dictionary, DeferredWrapper&& promise)
>  {
> +    ASSERT(input);

We should make input a FetchRequest&, then we should check the pointer before calling this.  Otherwise this could lead to null pointer issues.

> Source/WebCore/Modules/fetch/WorkerGlobalScopeFetch.cpp:43
> +void WorkerGlobalScopeFetch::fetch(WorkerGlobalScope& scope, FetchRequest* input, const Dictionary& dictionary, DeferredWrapper&& promise)
>  {
> -    promise.reject(ASCIILiteral("Fetch is not yet implemented"));
> +    ASSERT(input);

ditto

Changing that requires updating the binding generator.
I agree this would be a good move.
I 'd like if possible to ship that patch before updating the binding generator.

Then add null checks, early returns, and fixme comments.  Loading code with unchecked null pointers causes scary problems.

These null checks would be redundant with binding generated code.
Let's fix the binding generator then.

Mac HTTP backend seems to add a Content-Length: 0 header, while soup backend does not.
I added a specific GTK baseline for that test in the landing patch.
