While investigating some REST API updates I've discovered that there is a
lot of duplicated code across the various OpenStack components.
For example, the paginate_query function exists in all these locations and
there are a few slight differences between most of them:
https://github.com/openstack/ceilometer/blob/master/ceilometer/openstack/common/db/sqlalchemy/utils.py#L61
https://github.com/openstack/cinder/blob/master/cinder/openstack/common/db/sqlalchemy/utils.py#L37
https://github.com/openstack/glance/blob/master/glance/openstack/common/db/sqlalchemy/utils.py#L64
https://github.com/openstack/heat/blob/master/heat/openstack/common/db/sqlalchemy/utils.py#L62
https://github.com/openstack/keystone/blob/master/keystone/openstack/common/db/sqlalchemy/utils.py#L64
https://github.com/openstack/neutron/blob/master/neutron/openstack/common/db/sqlalchemy/utils.py#L61
https://github.com/openstack/nova/blob/master/nova/openstack/common/db/sqlalchemy/utils.py#L64
Does anyone know if there is any work going on to move stuff like this into
oslo and then deprecate these functions? There are also many functions
that process the REST API request parameters (getting the limit, marker,
sort data, etc.) that are also replicated across many components.
If no existing work is done in this area, how should this be tackled? As a
blueprint for Juno?
