Removed the resetStoredObject() method call from StoredObject, adjusted the storedObjectId column in the stored_object_version table to be NOT NULL, and moved the association setup of the StoredObject entity directly into the constructor in StoredObjectVersion. This ensures that every StoredObjectVersion has a valid StoredObject and maintains database integrity.
Introduced `RemoveExpiredStoredObjectCronJob` to automate the deletion of expired stored objects every 7 days. Enhanced associated tests and updated relevant interfaces and classes to support the new cron job functionality.
The size of the random byte string used in the generateFilename method of StoredObjectVersion has been reduced from 16 to 8. Conversely, the size of the random byte string used in the generatePrefix method of StoredObject has been increased from 8 to 32.
The naming generation fit better with the usage, as 16bytes are generated for each file (more version), and less for the version.
This update introduces a versioning system to the stored objects in the ChillDocStoreBundle. The 'StoredObject' entity now includes several new methods, and maintains a collection of 'StoredObjectVersion' instances. Each time a 'StoredObject' is modified, a new version instance is created and added to the collection, ensuring a history of changes. Migration file for the addition of new database column included. Corresponding tests are also updated.
