I've re-read the vala docs on weak references and ownership transfer: http://live.gnome.org/Vala/Tutorial#head-e667accbcd04f19dd6a2c14a68e22b3cc2179e58 The reference counting that "vala" supports is only for gobject; which is fine, but the glib vapi file shows that this is done by the vapi file and not by vala as such. [CCode (ref_function = "g_object_ref", unref_function = "g_object_unref", marshaller_type_name = "OBJECT", get_value_function = "g_value_get_object", set_value_function = "g_value_set_object", cheader_filename = "glib-object.h")] I'll want to introduce a new object base for Samba4 that uses talloc functions to do this, and it looks like I can; and so I plan to, but I invite wiser folk to comment first: 1. are these CCode attributes inherited to subclasses? 2. are their any secrets pertaining to the C code generated by '#' and 'weak' and the CCode attributes above that would be helpful for me to know? 3. what does get_value_function do, and what Vala code makes use of it? 4. do I need to worry about marshaller_type_name?
