Those objects are intentionally not integrated into the database code so
far. This is to quicken access to their definitions to implement
push-notifications for networks.
Segments are part of the network object. Since we need to reduce the
number of SQL queries executed per resource, and we want to include
segmentation information for networks, Network model was extended with
segments relationship that makes the information available on every
network resource fetch from the database. This change required some
change in test_dhcp_agent_scheduler to expire a session used in the
tests to avoid obsolete segment state to be reused to validate
scheduling.
This implementation of the object is not complete for the job of
updating the resource in database. For example, tags are not yet exposed
on the object; also attributes like availability_zones, or external
network attributes, are not covered. Those attributes are hopefully
needed on server side only, so until we adopt the object for server
side, it should be ok to live without them.
Another database related thing still missing in this patch is lack of
RBAC support for the object. To complete this support,
a real get_bound_tenant_ids should be put onto the object, instead of
the current no-op stub.
This patch also includes some rearrangements that simplified the work.
Specifically, all network related objects are consolidated in the
neutron.objects.network module, instead of being scattered through the
code base. Also, some setup code from test_policy relevant to RBAC was
moved into the base test class so that it can be utilized by other RBAC
enabled objects, like network.
