Unreleased

0.1.0-alpha-3 - 2024.09.11

Changed

• Updated dependencies to latest stable versions.

• Catch SQL exceptions due to constraint violations locally, instead of letting them bubble up to the application.

• [BREAKING CHANGE] Use namespaced keywords to grant and deny permissions.

• [BREAKING CHANGE] The context hierarchy model has changed. Previously it was implemented as a regular tree, and a given context could only have a single parent context (ancestor), and there was a single root context (represented by a context whose parent context was nil). Now the implementation is a full Directed Acyclic Graph (DAG), where each context can have zero or more parent contents. This means that we can also have multiple independent root contexts (contexts that don't have any ancestors).

  As a consequence, the underlying database model has changed. A new table is used (rbac_context_parent), and the parent-child relationship information needs to be moved from the rbac_context table to the new rbac_context_parent table. Something like the following SQL queries should be enough:

  BEGIN;
  -- ;;
  CREATE TABLE IF NOT EXISTS rbac_context_parent
    (child_id UUID NOT NULL,
     parent_id UUID NOT NULL,
     PRIMARY KEY (child_id, parent_id),
     CONSTRAINT rbac_context_parent_child_id_fk FOREIGN KEY(child_id) REFERENCES rbac_context(id),
     CONSTRAINT rbac_context_parent_parent_id_fk FOREIGN KEY(parent_id) REFERENCES rbac_context(id));
  -- ;;
  INSERT INTO rbac_context_parent (child_id, parent_id)
    (SELECT
         id AS child_id,
         parent AS parent_id
     FROM
         rbac_context
     WHERE parent IS NOT NULL);
  -- ;;
  ALTER TABLE rbac_context DROP COLUMN parent;
  -- ;;
  COMMIT;
  

0.1.0-alpha-2 - 2023.04.24

Changed

• Rename has-permission to has-permission? to better convey the fact that this is a predicate function.

0.1.0-alpha-1 - 2023.04.24

• First public release. This is alpha quality software.
