The comment says we use a custom binding, but it looks like we're not? It looks
the same as the other methods.

[gavinp, 2014/08/06 02:00:05]

It's not quite custom, just generic. The use "any..." required upstream changes
to V8Binding.h, you can see those in https://codereview.chromium.org/440243003/
, but, because the API keeps changing, we no longer need "any..." arguments, so
that upstream CL is now closed.

[falken, 2014/08/06 04:46:28]

Ah I see. "custom binding" made me think of Blink IDL's [Custom] attribute.

+  // [CallWith=ScriptState] Promise add((Request or ScalarValueString)... requests);
+  [CallWith=ScriptState] Promise add(any... requests);

[falken, 2014/07/31 15:28:21]

The spec has add and addAll. Why are we different?

[gavinp, 2014/08/06 02:00:05]

Because the spec has been changing many times per day, and I wrote this IDL at
the beginning of writing this CL. I'll update to the most recent spec.

+
+  // [CallWith=ScriptState] Promise put((Request or ScalarValueString) request, Response response);
+  [CallWith=ScriptState] Promise put(Request request, Response response);
+  [CallWith=ScriptState] Promise put(ScalarValueString request, Response response);
+
+  // [CallWith=ScriptState] Promise delete((Request or ScalarValueString) request, optional Dictionary queryParams);
+  [CallWith=ScriptState, ImplementedAs=deleteFunction] Promise delete(Request request, optional Dictionary queryParams);
+  [CallWith=ScriptState, ImplementedAs=deleteFunction] Promise delete(ScalarValueString request, optional Dictionary queryParams);
+
+  // [CallWith=ScriptState] Promise keys(optional (Request or ScalarValueString) request, optional Dictionary queryParams);
+  [CallWith=ScriptState] Promise keys(optional Request request, optional Dictionary queryParams);
+  [CallWith=ScriptState] Promise keys(ScalarValueString request, optional Dictionary queryParams);
+
+  [CallWith=ScriptState] Promise batch(sequence<Dictionary> batchOperations);

[falken, 2014/07/31 15:28:21]

batch doesn't seem in the spec, what's up?

[gavinp, 2014/08/06 02:00:05]

Ditto
