# Summary This PR is the next update to the persistency subsystem. The goal of this PR is to provide more framework like functions to allow more types of content to be made persistent. Currently only volatile game objects created during a round can be (*in a [clean](https://www.youtube.com/watch?v=rZ3ETK7-ZM8) way*) saved and made persistent. This update attempts to provide methods to make *everything*¹ persistent. This introduces persistent generics and history. ## Database The following things are going to be changed and added in the database (open in new tab for better visibility, PNG file includes the drawIO code): <img width="1692" height="1041" alt="aurora_persistency_db drawio" src="https://github.com/user-attachments/assets/ea53f419-f9aa-4592-af8f-3a8d5edf3177" /> **Deviations on database implementation from diagram:** - Removed unique constraint on history table - Prevented adding multiple records per round per attribute. ## Framework surface changes - MC/VV: Moved global object track register to subsystem var space. - MC/VV: Point of interest: Added history_cache and generic_cache to subsystem var space. - MC/VV: Updated subsystem stat entry message, now providing information on cache sizes of new types. - Added `singleton/persistent_type` defines (Type, clean-up rules, finalization hook) and macros allowing new definitions of said types. - Added cache structures that are also used for returns on public procs in generics and history persistent types. - Major new framework features: Persistent history (example: Mining yield records) and persistent generics (example: Persistent Horizon overmap position). See documentation for more information. DrawIO diagram for documentation, includes source in it (open in new tab): <img width="200" height="200" alt="Persistence-subsystem-flowchart drawio" src="https://github.com/user-attachments/assets/51f28331-f999-49a2-a7cc-58278f7ae416" /> ## Tasks (These lists are not comprehensive.) **General** - [x] Update DB - Write SQL scripts. - [x] Add subsystem modular files for generics and history. - [x] Add type definition logic, macros. - [x] Add type-DB init logic. - [x] Logging. - [x] A lot of testing. *A lot.* - [x] Changelog. - [x] Self-Review. - [x] Update documentation on the persistence subsystem. **"Persistent history"** - [x] Add init logic. - [x] Add finalize logic. - [x] Add framework surface procs. - [x] Get last record. - [x] Get last X records. - [x] Add record. - [x] Add character ID related validation. - [x] Add initial example mechanic. **"Persistent generics"** - [x] Add init logic. - [x] Add finalize logic. - [x] Add framework surface procs. - [x] Save. - [x] Load. - [x] Add initial example mechanic. ## Changes Too many changes to be listed here - Check changelog and actual changes. ## Warning There are certain use/test cases that *cannot* be tested locally due to missing preexisting data in the database. This should only affect new data structures (new persistent types), not existing data. ¹ _Large scale persistent mapping is excluded for this version._ --------- Co-authored-by: Copilot <copilot@github.com>
