- Implement KeyConfirmationQueue.delete_expired_queue_items to delete items
older than a given number of hours.
- Introduce configuration parameter to specify maximum number of hours. It
defaults to 1 hour.
- Update documentation to explain that we never assign ST_TO_BE_DELETED.
- Provide a new reuqired parameter: [database]pooling_mode and use it during
SQLAlchemy engine initialisation.
- Update tests and configuration (including sample configuration).
- Adjust repository unit test to load config during setup.
- Pass an engine instance to repository constructors instead of connections.
Engine keeps a connection pool and we rely on it.
- Don't pass table definitions to repository constructors.
- Keep an internal reference to Engine in lacre.repository.
- Implement KeyConfirmationQueue.count_keys.
- Keep only one class to provide access to identities stored in the database.
- Remove old code and its tests.
- Align KeyRing and IdentityRepository APIs.
- Implement a (very) simple unit test for IdentityRepository.
Introduce new Python modules:
- lacre.notify -- to send notifications from the cron script;
- lacre.dbschema -- to keep database schema definition as code (SQLAlchemy);
- lacre.repositories -- to define key and identity repositories with high
level APIs that we can then use elsewhere.
Also:
- rework GnuPG.add_key to return fingerprint so we can use it in the cron
script;
- rename cron-job's logger name, replacing dash with an underscore as logging
module doesn't like dashes.
