Sounds good to me. The list base objects don't have methods to make changes to the list - so it would be a case of iterating looking at each object in the list. That would be ok.
Do we need the contents of the lists to be modified without assigning a new list? - that would need a little more work to allow the changes and to track them there too.

Well, like the Instance object does, you can override obj_what_changed() to expose that fact to the caller. However, I think it might be good to expand the base class to check, for any NovaObject fields, for the obj_what_changed() of the child. How does that sound? --Dan _______________________________________________ OpenStack-dev mailing list OpenStack-dev@lists.openstack.org http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev
