timothy	05542946ad	fix(668): reach accented facet values via a registered Unicode fold on SQLite ... SQLite's LOWER() folds ASCII only -- lower('Édith') is 'Édith' unchanged -- so the EF-sourced facet fields UNDER-matched any stored value whose prefix carries an uppercase non-ASCII character. An under-match is unrecoverable: no later stage can reintroduce a row SQL never returned. Adds a SECOND, ADDITIVE query taken only when the provider is SQLite and q contains a non-ASCII character: raw Dapper SQL folding through etv_upper(), a SqliteConnection.CreateFunction scalar implementing ToUpperInvariant. Every other case -- all-ASCII q, and MySQL for all q -- runs the existing EF query byte-identically. MySQL needed no change and gets none: verified on MySQL 8.4 that its LOWER() is Unicode-aware and its ci collation makes the predicate OVER-match, which the existing ordinal filter already discards. The fold is ToUpperInvariant because OrdinalIgnoreCase equality is a strict SUBSET of invariant-uppercase equality, so the SQL stage yields a superset of the final filter's matches and can never under-match. Note OrdinalIgnoreCase is NOT "invariant-upper then ordinal": ToUpperInvariant('ſ') is 'S', yet "ſweet".StartsWith("S", OrdinalIgnoreCase) is false. Tests pin that. No migration, no model change; both provider snapshots are untouched. Refs #668 Decisions-Edit: yes	2026-07-27 20:36:28 +02:00
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	8f7d240fc8	feat(api): REST foundation + Channels CRUD (#34) ... First slice of the REST API (ersatztv#2). Idiomatic REST over existing MediatR handlers; design in docs/rest-api.md. Foundation: NotFoundError : BaseError (Core) to split 404 from 422; ApiResults mapping helpers (Either/Option -> 201+Location / 200 / 204 / 404 / 422), additive (existing *ToActionResult untouched); ApiKeyAuthorizationFilter (optional X-Api-Key on mutating actions, gated by Api:WriteKey, no-op when unset) — independent of the IPTV JWT toggle so Jellyfin/Dispatcharr reads are unaffected, applied at controller-class level so every mutating action incl. ResetPlayout is covered fail-safe. Channels: POST /api/channels (201+Location), PUT/{id} (200/404), DELETE/{id} (204/404), GET/{id} (200/404). Request DTOs -> existing commands; responses reuse ChannelViewModel. Ported page-only validations into handlers (ShowInEpg-when-disabled, external-logo-URL, Group NotEmpty) + FFmpegProfile/Watermark/Filler existence on update for create-parity. Fixed a latent 500: the .Filter(c>0) existence pattern threw TaskCanceledException on not-found; rewritten to AnyAsync. Tests (NUnit, TZ=UTC): handler success/404/422, ApiResults mapping, API-key filter, controller status/Location/mapping, a controller-security regression net, and a create->read->delete EF integration test on a new in-memory SQLite harness. ErsatzTV.Tests 46/46, Architecture 5/5. Refs #34 Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>	2026-06-27 15:51:06 +02:00
