What was wrong with the way it was before?

[sashab, 2013/02/04 05:09:27]

The old code did stuff like:

(for a single schema)
    type_generator = cpp_type_generator.CppTypeGenerator(
        root_namespace, namespace, namespace.unix_name)
    for referenced_namespace in api_model.namespaces.values():
      if referenced_namespace == namespace:
        continue
      type_generator.AddNamespace(
          referenced_namespace,
          referenced_namespace.unix_name)

(for a bundle schema)
  type_generator = cpp_type_generator.CppTypeGenerator(root_namespace)
  for referenced_namespace in api_model.namespaces.values():
    type_generator.AddNamespace(
        referenced_namespace,
        referenced_namespace.unix_name)

(see https://codereview.chromium.org/12041098/patch/3003/5006)

This just allows you to write this the second way, but also set the ._namespace
variable (which is used by the cpp-generator later). I'm guessing the bundle
generator doesn't use ._namespace, so it was still working even though it wasn't
being set.

+    if self._namespace is None:
+      self._namespace = namespace
+
     self._cpp_namespaces[namespace] = cpp_namespace
     for type_name in namespace.types:
       # Allow $refs to refer to just 'Type' within namespaces. Otherwise they
