Description

I have code which looks like

  /**
   * ModulemdModuleMetadata:buildrequires: (type GLib.HashTable(utf8,utf8)) (transfer full)
   */
  properties [PROP_BUILDREQUIRES] =
    g_param_spec_boxed ("buildrequires",
                        "Module BuildRequires",
                        "A dictionary property representing the required "
                        "build dependencies of the module. Keys are the "
                        "required module names (strings), values are their "
                        "required stream names (also strings).",
                        G_TYPE_HASH_TABLE,
                        G_PARAM_READWRITE | G_PARAM_STATIC_STRINGS);

I've tried all transfer methods (none, container, full), but if I do

foo.props.buildrequires["bar"] = "baz"

And then print(foo.props.buildrequires), it is not modified. In get_property() I return g_hash_table_ref (self->buildrequires), so I expect that really to work.

Let me know if I should provide some more details or this is a bug or I'm just dumb.
