timothyandClaude Opus 4.8	2281f2e764	fix(308): idempotent concurrent Add*ToCollection instead of a composite-PK 500 ... Two concurrent adds of the same item both membership-check it absent, both insert the CollectionItem composite key, and the loser's SaveChangesForcingVersion threw an uncaught DbUpdateException (SQLite 19 / MySQL 1062) -> 500. Now the loser is an idempotent no-op. - ConcurrencyExtensions.TrySaveChangesForcingVersion: bool-returning sibling that catches only a classified unique/PK violation and returns false. - 10 single-item Add*ToCollection handlers: return Unit.Default (no-op, skip fan-out) on false — the racing winner already inserted + rotated + rebuilt. - Bulk AddItemsToCollection: retry on a fresh context against recomputed membership so a partial-overlap collision doesn't drop the non-colliding items (bounded loop; common no-collision path runs once). - Provider detection via a TvContext.IsUniqueConstraintViolation static delegate (matches the existing IsSqlite/LastInsertedRowId provider seam), wired from Startup to SqliteErrorClassifier / MySqlErrorClassifier. - Add*ToPlaylist is NOT affected (PlaylistItem has its own identity PK; a playlist may legitimately contain the same item more than once). Tests: a negative-control anchor proves the race genuinely throws a classified exception; end-to-end handler tests reproduce a real cross-connection race via a shared-cache SQLite harness + a SavingChanges interceptor (the single-conn in-memory fixture cannot). Every fix-dependent test verified to fail with the catch disabled.

timothyandClaude Opus 4.8	83f753b211	fix(api): #269 rotate aggregate ETag on Collection/Playout config siblings ... Complete the #253 optimistic-concurrency contract's cross-editor ETag rotation tail. The non-If-Match config siblings mutated editor-visible state without bumping Version, so a concurrent editor of the same root never invalidated. Now the Collection Add*/Remove handlers bump Collection.Version, and UpdateCollection / UpdatePlayout / the three ScheduleFile writers (which already force-wrote past a concurrent bump) now bump too — all via SaveChangesForcingVersion (no If-Match → force write, never 412/500). No-op idempotence (Fable-caught trap): these gate reindex/BuildPlayout fan-out on SaveChanges()>0, so an unconditional bump would fire spurious rebuilds on an idempotent re-add / same-value re-submit. Each now short-circuits a genuine no-op before the bump — Add handlers by an explicit membership check (also fixing a latent duplicate-CollectionItem insert), scalar writers by ChangeTracker.HasChanges(). Corrects #269's framing: the Add*ToCollection family is not repository-mediated (IMediaCollectionRepository is read-only); each handler writes via its own dbContext, so the scanner's separate membership path is unaffected (a background scan does not rotate the editor ETag). Tests: CollectionEtagRotationTests + PlayoutScheduleFileEtagRotationTests (rotation, no-op-without-bump-or-rebuild, force-write-past-concurrent-bump), no-op guard proven non-vacuous by inverting the membership check. Docs: api-conventions §7a + decisions.md. No new status codes / no OpenAPI change (these endpoints take no If-Match, never 412). The #265 RFC-7232 If-Match parser refinement is a separate PR. fixes #269 Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>	2026-07-12 19:40:32 +02:00
