Title:
notification.info_from_instance should use get()
Status in OpenStack Compute (Nova):
Opinion
Bug description:
notification.info_from_instance() reads many values from the instance
structure, including capacity vales that are populated from the
instance_system_metadata table. However there are cases where these
values are not present - for example if a deleted instance is passed
in then the DB queries do not always do the joins. This results in a
KeyError exception.
Whilst such cases are triggered by bugs the notification code should
be more robust and use .get() methods instead.
