  #13: TemporalRepository save — stable-live + historical-copy semantics

  u.schuster released this 2026-04-30 00:10:03 +02:00 | 8 commits to main since this release

  The decorator's save() flow now preserves the live row's id PK across
  updates and captures each prior version as a fresh row with a new id.
  This unblocks fewo-webapp#459: the consumer's composite-FK schema needs
  stable child references to the live row (UNIQUE(entity_id, valid_until)
  with ON UPDATE CASCADE on every child FK), which the previous
  close-then-insert flow couldn't provide.

  New flow on update (when a live row exists for entity_id):

  1. Clone the live row in memory (cloneDto via oatpp reflection),
     assign a fresh id and set valid_until=now, save → INSERT historical.
  2. Set the new dto's id=live.id (preserve PK), valid_from=now,
     valid_until=SENTINEL, save → inner UPDATEs the live row in place by
     PK.

  Inner adapter contract changes from "upsert keyed by (entity_id,
  valid_from)" to "upsert keyed by id (per-row PK)". TemporalFieldTraits
  gains an id() accessor; OATPP_AUTHKIT_REGISTER_TEMPORAL grows from 4 to
  5 args (Dto + IdMember + EntityIdMember + FromMember + UntilMember).

  Tests: test_repository_decorators asserts livePk stability across saves
  and fresh historicalPk per version; remaining decorator tests updated to
  the 5-arg macro form. README's TemporalRepository.hpp row rewritten to
  describe the new write semantics.

  Bumped CMake version 0.7.0 → 0.8.0 (semantic break — save() no longer
  reallocates the live PK; consumers depending on the old contract need
  audit).

  Closes #13
