Title:
get_all_flavor cannot return all flavors if the deleted flavor has
same name
Status in OpenStack Compute (Nova):
Fix Released
Bug description:
Now it is allowed that the flavor with specified name was deleted, and
later a new flavor is created with the same name, by this way, you can
there are two records in the DB (table "instance_types") with the same
name but different id/flavorid.
But if you are going to retrieve all flavors via
nova.compute.flavors:get_all_flavors(inactive=True), you would find
that only the last flavor which has the same name can be fetched. This
is because that all instance types retrieved from DB will be set into
a dict and the 'name' is used as the key.
