There are several changes here:
1) Adds some MutableThis methods to Optional, Nullable, and dictionaries to
effectively allow doing a const_cast without knowing the actual type being
templated over. I needed this because I do not in fact know that type in
the relevant code. I'm open to suggestions for a better name for this
method.
2) Adds some operator& to RootedJSValue to make it look more like a JS::Value,
and in particular so I can JS_WrapValue the thing in it.
3) Adds a Slot() method to NonNullLazyRootedObject, just like NonNull has.
4) Adds an operator& to LazyRootedObject to make it look more like JSObject* so
I can JS_WrapObject the thing in it.
5) Implements the actual rewrapping of the arguments into the content compartment.
6) Fixes a small preexisting bug in which we didn't look at named constructors
in getTypesFromDescriptor (this was causing my tests to not compile).
7) Changes Xrays to not enter the content compartment when calling a WebIDL
constructor.
8) Adds some friend API to report things as not being functions.
The big block in getRetvalDeclarationForType is just direct cut/paste from CGCallGenerator plus the addition of the sequence case. The IDL parser changes were OKed by khuey; they're needed so that we don't have to worry about the ordering of sequence with conversions for strings and primitives.
In the new setup, all per-interface DOM binding files are exported into
mozilla/dom. General files not specific to an interface are also exported into
mozilla/dom.
In terms of namespaces, most things now live in mozilla::dom. Each interface
Foo that has generated code has a mozilla::dom::FooBinding namespace for said
generated code (and possibly a mozilla::bindings::FooBinding_workers if there's
separate codegen for workers).
IDL enums are a bit weird: since the name of the enum and the names of its
entries all end up in the same namespace, we still generate a C++ namespace
with the name of the IDL enum type with "Values" appended to it, with a
::valuelist inside for the actual C++ enum. We then typedef
EnumFooValues::valuelist to EnumFoo. That makes it a bit more difficult to
refer to the values, but means that values from different enums don't collide
with each other.
The enums with the proto and constructor IDs in them now live under the
mozilla::dom::prototypes and mozilla::dom::constructors namespaces respectively.
Again, this lets us deal sanely with the whole "enum value names are flattened
into the namespace the enum is in" deal.
The main benefit of this setup (and the reason "Binding" got appended to the
per-interface namespaces) is that this way "using mozilla::dom" should Just
Work for consumers and still allow C++ code to sanely use the IDL interface
names for concrete classes, which is fairly desirable.
