Code Review
This pull request introduces a namespace field to the Action proto message, associating actions with namespaces and propagating this through the gRPC API. However, a critical security vulnerability has been identified: the backend implementation (Go code and SQL queries) has not been updated to utilize these new namespace fields, leading to a security bypass where namespace isolation is not enforced. Additionally, the breaking change in GetActionRequest will disrupt existing internal logic for updating and deleting actions. It is recommended to complete the implementation of namespace filtering in the backend and update internal service calls to ensure consistency and security. Furthermore, consider adding comments to the new namespace_id and namespace_fqn fields in actions.proto to improve clarity and maintainability.

Generally looks good. Left one line specific comment and then I have more general comment: Should we make the namespace_id/namespace_fqn oneof fields optional for backwards compatibility pre-migration? At the very least it feels strange to require namespaces for the standard (immutable?) actions e.g. read.
Maybe platform should have a default namespace that the standard actions live under? |
@c-r33d @alkalescent the ticket specified "Standard actions create, read, update, delete remain immutable in the db and present within every namespace" and my current plan to do that is:
so overall it will be more rows but less branching. per-namespace standard actions trade some storage overhead for simpler and hopefully safer logic lmk your thoughts |

Proposed Changes
This pull request introduces namespace support to the policy service, primarily focusing on
Actions. It adds anamespacefield to theActionprotobuf definition and integratesnamespace_idandnamespace_fqnfields into request messages for creating, retrieving, and listing actions. These new fields are accompanied by robust validation rules to ensure data consistency and proper identification of namespaces. The changes also include updates to the gRPC documentation and expanded unit tests to cover the new validation logic.Highlights
namespacefield of typeNamespacehas been introduced to thepolicy.Actionmessage inservice/policy/objects.proto, providing a namespace context for actions.GetActionRequest,ListActionsRequest, andCreateActionRequestinservice/policy/actions/actions.protonow includenamespace_id(UUID) andnamespace_fqn(URI) fields, which are required and mutually exclusive (oneof).namespace_idandnamespace_fqnfields, ensuring they adhere to UUID and URI formats respectively, and that one of them is always provided.Checklist
