<objective>
|
||||
Create the database schema definitions and migration 6 for multi-library support.
|
||||
|
||||
Purpose: This is the foundational schema change that all subsequent multi-library phases depend on. Fresh installs get the new schema directly; existing databases are migrated atomically with a pre-migration backup.
|
||||
|
||||
Output: Updated SQL schema files for fresh databases + migration 6 implementation in database.go

|
||||
Create the schema files that define the target state for fresh database installs. These files are executed via `go:embed` in `NewDB()` — they use `CREATE TABLE IF NOT EXISTS` / `CREATE VIEW IF NOT EXISTS` so they're idempotent.
|
||||
|
||||
**1. Create `libraries.sql` (NEW FILE):**
|
||||
```sql
|
||||
CREATE TABLE IF NOT EXISTS libraries (
|
||||
id INTEGER PRIMARY KEY,
|
||||
name TEXT NOT NULL,
|
||||
path TEXT NOT NULL UNIQUE,
|
||||
created_at DATETIME NOT NULL DEFAULT CURRENT_TIMESTAMP
|
||||
);
|
||||
```
|
||||
Per user decision: minimal table — name, path, created_at only. No scan metadata columns (Phase 11 adds those). No scan_concurrency column (global default fallback for now).
|
||||
|
||||
**2. Update `audio_files.sql`:**
|
||||
Add `library_id` column with FK to libraries table. For fresh databases the column should be `NOT NULL` with no DEFAULT (fresh installs always create a library first). However, since the CREATE TABLE runs before any libraries exist, use `DEFAULT 0` to allow the table creation to succeed — the migration and scan pipeline will always set the correct value.
|
||||
|
||||
Add after the `basename` column:
|
||||
```sql
|
||||
library_id int NOT NULL DEFAULT 0,
|
||||
```
|
||||
Add FK constraint:
|
||||
```sql
|
||||
FOREIGN KEY(library_id) REFERENCES libraries(id)
|
||||
```
|
||||
Add index after the table:
|
||||
```sql
|
||||
CREATE INDEX IF NOT EXISTS idx_audio_files_library_id
|
||||
ON audio_files(library_id);
|
||||
```
|
||||
|
||||
**3. Update `playlist_tracks.sql`:**
|
||||
Change `audio_file_id` from `NOT NULL` to nullable (remove NOT NULL). Change FK from `ON DELETE CASCADE` to `ON DELETE SET NULL`. Add phantom metadata columns with NULL defaults:
|
||||
```sql
|
||||
CREATE TABLE IF NOT EXISTS playlist_tracks (
|
||||
id INTEGER PRIMARY KEY,
|
||||
playlist_id INTEGER NOT NULL,
|
||||
audio_file_id INTEGER,
|
||||
position INTEGER NOT NULL,
|
||||
phantom_title TEXT,
|
||||
phantom_artist TEXT,
|
||||
phantom_album TEXT,
|
||||
phantom_duration_ms INTEGER,
|
||||
phantom_genre TEXT,
|
||||
phantom_cover_art_path TEXT,
|
||||
FOREIGN KEY(playlist_id) REFERENCES playlists(id) ON DELETE CASCADE,
|
||||
FOREIGN KEY(audio_file_id) REFERENCES audio_files(id) ON DELETE SET NULL
|
||||
);
|
||||
```
|
||||
Keep the existing indexes on playlist_id and audio_file_id.
|
||||
|
||||
**4. Update `track_metadata_view.sql`:**
|
||||
Add `af.library_id` to the SELECT list — insert it after `af.file_size` (last column). The JOIN structure stays identical:
|
||||
```sql
|
||||
af.file_size,
|
||||
af.library_id
|
||||
FROM audio_files af
|
||||
```
|
||||
|
||||
**IMPORTANT:** The `libraries.sql` file must sort BEFORE `audio_files.sql` alphabetically so it's executed first (the FK depends on it). Verify: "libraries" < "audio_files" — NO, "a" < "l" so audio_files runs first. This is a problem because audio_files references libraries. Solutions:
|
||||
- Rename to `001_libraries.sql` — but this changes naming convention
|
||||
- Use the migration to handle existing DBs and rely on SQLite's deferred FK check for fresh DBs — since `PRAGMA foreign_keys = ON` is set AFTER schema files run? No — PRAGMAs run BEFORE schemas in `NewDB()`.
|
||||
|
||||
Actually, check the code: `applyPRAGMAs()` runs `PRAGMA foreign_keys = ON` before schema files execute. So `audio_files.sql` will fail FK check if `libraries` table doesn't exist yet. The fix: name the file so it sorts before audio_files. Use `_libraries.sql` (underscore sorts before 'a' in ASCII). Or better: just create the libraries table inside audio_files.sql as a preceding statement? No, that's messy.
|
||||
|
||||
Best approach: Name the file so it executes first. Files are read from embedded FS sorted by `ReadDir` (alphabetical). Prefix: `00_libraries.sql` ensures it runs before any other schema. This is clean and explicit.
|
||||
|
||||
Actually — re-read the `NewDB()` code. It iterates `dirEntries` from `ReadDir` which returns entries sorted by name. So we need `libraries.sql` to sort before `audio_files.sql`. Since 'l' > 'a', we can't use `libraries.sql` directly. Use `_libraries.sql` (underscore = 0x5F sorts after uppercase letters in ASCII but before lowercase... actually in Go's `ReadDir`, entries are sorted case-sensitively). Since all existing files are lowercase, and '_' (0x5F) < 'a' (0x61), `_libraries.sql` will sort first.
|
||||
|
||||
Wait — there are other options. The simplest: just temporarily disable FK checks in `NewDB` during schema file execution, then re-enable. But that changes production behavior.
|
||||
|
||||
Simplest correct approach: just make the FK constraint on audio_files use a CREATE INDEX rather than inline FK, and handle the FK check in the migration. But that loses FK enforcement on fresh DBs.
|
||||
|
||||
Actually the cleanest fix: since `libraries.sql` needs to exist before `audio_files.sql`, and Go's `ReadDir` sorts alphabetically, and `_` < `a`: name it `_libraries.sql`. This runs before all other schema files.
|
||||
|
||||
Alternative: just don't add the FK constraint to the CREATE TABLE DDL and instead add it during migration / via a separate step. But SQLite doesn't support ALTER TABLE ADD CONSTRAINT.
|
||||
|
||||
Go with `_libraries.sql`. It's a minor naming convention change but ensures correct execution order.

Add migration 6 to the `runMigrations()` function in `database.go`. This is the most complex migration yet — follow the established patterns from migration 5 (table rebuild with FK OFF).
|
||||
|
||||
**Step 1: Add backup function.**
|
||||
|
||||
Create `backupDatabase()` function that copies the database file before migration 6 runs. Per user decision: timestamp-based naming (e.g., `yj.db.bak.20260309`), no automatic cleanup, logged at INFO level.
|
||||
|
||||
```go
|
||||
// backupDatabase copies the database file to a timestamped backup
|
||||
// before running a destructive migration. Returns the backup path.
|
||||
func backupDatabase(
|
||||
dbPath string, logger *slog.Logger,
|
||||
) (string, error) {
|
||||
backupPath := dbPath + ".bak." + time.Now().Format("20060102")
|
||||
// Use io.Copy from source to destination
|
||||
// Log at INFO: "database backup created", "path", backupPath
|
||||
// Return backupPath, nil on success
|
||||
}
|
||||
```
|
||||
|
||||
The `dbPath` must be passed to `runMigrations`. Update the signature:
|
||||
```go
|
||||
func runMigrations(ctx context.Context, db *sql.DB, logger *slog.Logger, dbPath string) error
|
||||
```
|
||||
Update the call site in `NewDB()` to pass `sqliteDBFilePath`.
|
||||
|
||||
**Step 2: Add migration 6 block in runMigrations.**
|
||||
|
||||
After the `version < 5` block, add:
|
||||
|
||||
```go
|
||||
// Migration 6: multi-library support.
|
||||
if version < 6 {
|
||||
if err := migration6MultiLibrary(
|
||||
ctx, db, logger, dbPath,
|
||||
); err != nil {
|
||||
return err
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
**Step 3: Implement `migration6MultiLibrary()` function.**
|
||||
|
||||
This is a large function — follow migration 5's pattern. The steps MUST execute in this exact order inside a single transaction (DATA-04: atomic):
|
||||
|
||||
```go
|
||||
func migration6MultiLibrary(
|
||||
ctx context.Context,
|
||||
db *sql.DB,
|
||||
logger *slog.Logger,
|
||||
dbPath string,
|
||||
) error {
|
||||
logger.Info("applying migration 6: multi-library support")
|
||||
|
||||
// 1. Backup database BEFORE any changes.
|
||||
backupPath, err := backupDatabase(dbPath, logger)
|
||||
// Handle error — if backup fails, abort migration.
|
||||
logger.Info("pre-migration backup created", "path", backupPath)
|
||||
|
||||
// 2. Read TOML config to get existing library directory.
|
||||
// Use system.GetUserConfigDirPath() to find config.toml.
|
||||
// Parse ONLY the [Library] section to get DirectoryPath.
|

// If no config or no DirectoryPath, existingDir = "" (fresh install).
|
||||
configDir, err := system.GetUserConfigDirPath()
|
||||
// Read config.toml, decode [Library].DirectoryPath
|
||||
// Use a minimal struct: struct{ Library struct{ DirectoryPath string } }
|
||||
|
||||
// 3. Disable FK checks for table rebuild.

}
|
||||
```
|
||||
|
||||
**Step 4: Implement `removeLibraryDirFromTOML()` helper.**
|
||||
|
||||
Read the TOML file, set DirectoryPath to empty string, write back. Use the same `os.WriteFile` with `0o644` permissions pattern from the config package. If the file doesn't exist or the section is missing, no-op (per user decision: old config key ignored).
|
||||
|
||||
**IMPORTANT notes for the executor:**
|
||||
- Import `path/filepath` for `filepath.Base()` and `time` for backup timestamp.
|
||||
- Import `io` for `io.Copy` in backup function.
|
||||
- Import `os` for file operations.
|
||||
- Import `github.com/BurntSushi/toml` for TOML read/write in migration.
|
||||
- Add `// SAFETY:` comments on all hand-crafted SQL (consistent with Phase 6 convention).
|
||||
- The backup runs OUTSIDE the transaction (you can't copy a file inside a SQL transaction). The migration SQL steps should be wrapped in a transaction for atomicity. Use `db.BeginTx()` around steps 3-12.
|
||||
- Actually, PRAGMA foreign_keys cannot run inside a transaction. Structure: backup → PRAGMA FK OFF → BEGIN TX → steps 4-11 → COMMIT → PRAGMA FK ON → PRAGMA user_version = 6.
|
||||
- Wait — PRAGMA user_version also can't run inside a transaction reliably on all SQLite versions. Follow migration 5's pattern: no explicit transaction, just sequential statements with PRAGMA FK OFF/ON wrapping.
|
||||
- For fresh installs with no TOML config: existingDir="" and defaultLibID=0. The ALTER TABLE ADD COLUMN with DEFAULT 0 is fine — there are no audio_files rows on a fresh install anyway. The schema files handle fresh DB creation.
|
||||
- The `library_id NOT NULL DEFAULT 0` on audio_files in the schema file means fresh-install audio_files don't require a library to exist yet. The scan pipeline (Phase 11) will set library_id correctly. DEFAULT 0 is a placeholder that won't satisfy the FK constraint, but since `PRAGMA foreign_keys` only checks on INSERT/UPDATE, and the CREATE TABLE runs before any data, this is safe.
|
||||
|
||||
Actually, that FK constraint with DEFAULT 0 is problematic. If FK checks are on and someone inserts a row without a library, it'll fail. For fresh installs the scan pipeline (Phase 11) will always set a real library_id. But to be safe, DON'T add a FK constraint in the CREATE TABLE for audio_files — add it only via the migration where we control the value. Wait, no — we want FK enforcement on fresh DBs too.
|
||||
|
||||
Better approach: Use `DEFAULT 1` in the schema file — but library ID 1 may not exist on fresh installs. Actually for fresh installs per user decision: "empty libraries table, user adds their first library when they want to scan." So there's no library to FK-reference. The scan pipeline in Phase 11 will create a library first, then scan.
|
||||
|
||||
The safest approach: keep the FK constraint and `NOT NULL DEFAULT 0` in the schema file. Since `PRAGMA foreign_keys = ON` is set, any INSERT into audio_files without a valid library_id will fail — which is correct behavior. The DEFAULT 0 only matters for the ALTER TABLE ADD COLUMN during migration where it backfills existing rows. We immediately set all rows to the correct library_id in the same migration.
|
||||
|
||||
Wait — for the ALTER TABLE ADD COLUMN in migration 6, the DEFAULT value must match the actual library ID. That's `defaultLibID` (dynamic). So the schema file's DEFAULT 0 is fine for CREATE TABLE (fresh DBs), and the migration uses a dynamic DEFAULT.
|
||||
|
||||
One more thing: on fresh DBs, audio_files will have `library_id INTEGER NOT NULL DEFAULT 0` with a FK to libraries. If someone tries to INSERT an audio_file with library_id=0 and no library with id=0 exists, the FK check will fail. This is actually CORRECT — you must create a library first. Good.
|
||||
|
||||
Let the executor figure out the exact DEFAULT handling. The key instruction is clear.

# Phase 10 Plan 1: Schema & Migration Summary
|
||||
|
||||
**Libraries table, audio_files.library_id FK, playlist_tracks phantom columns with SET NULL FK, migration 6 with pre-backup and TOML config cleanup**
|
||||
|
||||
## Performance
|
||||
|
||||
- **Duration:** 11 min
|
||||
- **Started:** 2026-03-09T13:29:50Z
|
||||
- **Completed:** 2026-03-09T13:41:26Z
|
||||
- **Tasks:** 2
|
||||
- **Files modified:** 10
|
||||
|
||||
## Accomplishments
|
||||
- Created libraries table schema with name, path, created_at columns
|
||||
- Added library_id FK to audio_files with index for filter performance
|
||||
- Rebuilt playlist_tracks with nullable audio_file_id (SET NULL FK) and 6 phantom metadata columns
|
||||
- Implemented migration 6 with 14-step process: backup, TOML read, FK OFF, create table, insert default library, add column, rebuild playlist_tracks, backfill phantom metadata, recreate VIEW, FK ON, TOML cleanup, version bump
|
||||
- Updated track_metadata VIEW to include library_id
|
||||
- Regenerated sqlc code and fixed all callers for nullable AudioFileID
|
||||
|
||||
## Task Commits
|
||||
|
||||
Each task was committed atomically:
|
||||
|
||||
1. **Task 1: Update SQL schema files for fresh installs** - `535855b` (feat)
|
||||
2. **Task 2: Implement migration 6 and pre-migration backup** - `1179f56` (feat)
|
||||
|
||||
## Files Created/Modified
|
||||
- `backend/database/sql/schemas/_libraries.sql` - New libraries table DDL
|
||||
- `backend/database/sql/schemas/audio_files.sql` - Added library_id column and FK
|
||||
- `backend/database/sql/schemas/playlist_tracks.sql` - Nullable audio_file_id, SET NULL FK, 6 phantom columns
|
||||
- `backend/database/sql/schemas/track_metadata_view.sql` - Added af.library_id to SELECT
|
||||
- `backend/database/database.go` - migration6MultiLibrary(), backupDatabase(), TOML helpers
|
||||
- `backend/database/sql/sqlcgen/models.go` - Library struct, updated AudioFile and PlaylistTrack
|
||||
- `backend/database/sql/sqlcgen/audio_files.sql.go` - Updated queries for library_id column
|
||||
- `backend/database/sql/sqlcgen/playlists.sql.go` - sql.NullInt64 for AudioFileID, phantom fields
|
||||
- `backend/database/testhelper.go` - Sentinel library row, updated runMigrations call
|
||||
- `backend/playlist/playlist.go` - sql.NullInt64 wrapping for AddPlaylistTrack calls
|
||||
|
||||
## Decisions Made
|
||||
- Used underscore prefix `_libraries.sql` to ensure correct embedded FS sort order (libraries must exist before audio_files FK reference)
|
||||
- Sentinel library row at id=0 in NewTestDB for backward compatibility with existing test data using DEFAULT library_id=0
|
||||
- TOML config cleanup uses generic `map[string]any` decode to preserve all config sections when removing only DirectoryPath
|
||||
- Backup function skips for in-memory databases (`:memory:` path check) to support test environments
|
||||
|
||||
## Deviations from Plan
|
||||
|
||||
### Auto-fixed Issues
|
||||
|
||||
**1. [Rule 3 - Blocking] Regenerated sqlc code and fixed compilation errors**
|
||||
- **Found during:** Task 1 (SQL schema updates)
|
||||
- **Issue:** Pre-commit hook auto-ran `sqlc generate` which updated generated code — AudioFileID changed from `int64` to `sql.NullInt64`, breaking 4 call sites in playlist.go
|
||||
- **Fix:** Added `database/sql` import to playlist.go and wrapped all AudioFileID assignments with `sql.NullInt64{Int64: id, Valid: true}`
|
||||
- **Files modified:** backend/database/sql/sqlcgen/{models,audio_files.sql,playlists.sql}.go, backend/playlist/playlist.go
|
||||
- **Verification:** `go build ./...` passes
|
||||
- **Committed in:** 535855b (Task 1 commit)
|
||||
|
||||
**2. [Rule 3 - Blocking] Fixed test FK constraint failures**
|
||||
- **Found during:** Task 2 (migration implementation)
|
||||
- **Issue:** Existing tests insert audio_files with DEFAULT library_id=0 but no library with id=0 exists after schema changes — FK constraint violated
|
||||
- **Fix:** Added sentinel library row (id=0, name='Test', path='/test') in NewTestDB() so all tests have a valid FK target
|
||||
- **Files modified:** backend/database/testhelper.go
|
||||
- **Verification:** `go test ./backend/database/... -count=1` passes (all 10+ test functions)
|
||||
- **Committed in:** 1179f56 (Task 2 commit)
|
||||
|
||||
**3. [Rule 1 - Bug] Fixed unchecked error returns on file Close()**
|
||||
- **Found during:** Task 2 (linter pre-commit check)
|
||||
- **Issue:** `src.Close()` and `dst.Close()` in backupDatabase() had unchecked error returns, caught by errcheck linter
|
||||
- **Fix:** Changed to `defer func() { _ = src.Close() }()` pattern (explicit discard)
|
||||
- **Files modified:** backend/database/database.go
|
||||
- **Verification:** `golangci-lint` passes with 0 issues
|
||||
- **Committed in:** 1179f56 (Task 2 commit)
|
||||
|
||||
---
|
||||
|
||||
**Total deviations:** 3 auto-fixed (2 blocking, 1 bug)
|
||||
**Impact on plan:** All fixes necessary for correctness and build health. No scope creep — sqlc regeneration and test fixes are direct consequences of the schema changes.
|
||||
|
||||
## Issues Encountered
|
||||
None — migration 6 follows established patterns from migration 5.
|
||||
|
||||
## User Setup Required
|
||||
None - no external service configuration required.
|
||||
|
||||
## Next Phase Readiness
|
||||
- Schema foundation complete for multi-library support
|
||||
- Ready for Plan 02 (sqlc query updates, if applicable) or Phase 11 (per-library scan pipeline)
|
||||
- All existing tests pass with new schema

|
||||
**1. Create `backend/database/sql/queries/libraries.sql` (NEW FILE):**
|
||||
|
||||
Define the core CRUD queries for the libraries table. These will be consumed by Phase 12 (Library CRUD API) but the type-safe generated code is needed now for migration tests and any early usage.
|
||||
|
||||
```sql
|
||||
-- name: CreateLibrary :one
|
||||
INSERT INTO libraries (name, path) VALUES (?, ?)
|
||||
RETURNING *;
|
||||
|
||||
-- name: GetLibrary :one
|
||||
SELECT * FROM libraries WHERE id = ? LIMIT 1;
|
||||
|
||||
-- name: GetLibraryByPath :one
|
||||
SELECT * FROM libraries WHERE path = ? LIMIT 1;
|
||||
|
||||
-- name: GetAllLibraries :many
|
||||
SELECT * FROM libraries ORDER BY name;
|
||||
|
||||
-- name: UpdateLibraryName :exec
|
||||
UPDATE libraries SET name = ? WHERE id = ?;
|
||||
|
||||
-- name: DeleteLibrary :exec
|
||||
DELETE FROM libraries WHERE id = ?;
|
||||
|
||||
-- name: CountLibraries :one
|
||||
SELECT COUNT(*) AS count FROM libraries;
|
||||
```
|
||||
|
||||
**2. Update `backend/database/sql/queries/playlists.sql`:**
|
||||
|
||||
The existing queries need updates for the new playlist_tracks schema:
|
||||
|
||||
a) **`AddPlaylistTrack`** — Add phantom metadata columns to the INSERT. The caller populates phantom data eagerly on every insert (per user decision):
|
||||
```sql
|
||||
-- name: AddPlaylistTrack :one
|
||||
INSERT INTO playlist_tracks (
|
||||
playlist_id, audio_file_id, position,
|
||||
phantom_title, phantom_artist, phantom_album,
|
||||
phantom_duration_ms, phantom_genre, phantom_cover_art_path
|
||||
) VALUES (?, ?, ?, ?, ?, ?, ?, ?, ?)
|
||||
RETURNING *;
|
||||
```
|
||||
|
||||
b) **`GetPlaylistTracks`** — Change JOIN to LEFT JOIN on audio_files (audio_file_id is now nullable). Include phantom columns in output so callers can display either live or phantom data:
|
||||
```sql
|
||||
-- name: GetPlaylistTracks :many
|
||||
SELECT pt.id, pt.playlist_id, pt.audio_file_id, pt.position,
|
||||
COALESCE(af.file_path, '') AS file_path,
|
||||
pt.phantom_title, pt.phantom_artist, pt.phantom_album,
|
||||
pt.phantom_duration_ms, pt.phantom_genre, pt.phantom_cover_art_path
|
||||
FROM playlist_tracks pt
|
||||
LEFT JOIN audio_files af ON pt.audio_file_id = af.id
|
||||
WHERE pt.playlist_id = ?
|
||||
ORDER BY pt.position;
|
||||
```
|
||||
|
||||
c) **`GetPlaylistTracksWithMetadata`** — Same LEFT JOIN change, and include phantom fallback columns. When audio_file_id is NULL (phantom), the live metadata JOINs return NULL and callers use phantom_* columns instead:
|
||||
```sql
|
||||
-- name: GetPlaylistTracksWithMetadata :many
|
||||
SELECT
|
||||
pt.id,
|
||||
pt.playlist_id,
|
||||
pt.audio_file_id,
|
||||
pt.position,
|
||||
COALESCE(af.file_path, '') AS file_path,
|
||||
COALESCE(af.length_milliseconds, 0) AS length_milliseconds,
|
||||
COALESCE(r.name, pt.phantom_title, '') AS title,
|
||||
COALESCE(ac.text, pt.phantom_artist, '') AS artist,
|
||||
COALESCE(rg.name, pt.phantom_album, '') AS album,
|
||||
COALESCE(ca.file_path, pt.phantom_cover_art_path, '') AS cover_art_path,
|
||||
CASE WHEN pt.audio_file_id IS NULL THEN 1 ELSE 0 END AS is_phantom
|
||||
FROM playlist_tracks pt
|
||||
LEFT JOIN audio_files af ON pt.audio_file_id = af.id
|
||||
LEFT JOIN recordings r ON af.recording_id = r.id
|
||||
LEFT JOIN artist_credit ac ON r.artist_credit_id = ac.id
|
||||
LEFT JOIN (
|
||||
SELECT recording_id, MIN(release_group_id) AS release_group_id
|
||||
FROM release_group_recordings
|
||||
GROUP BY recording_id
|
||||
) rgr ON r.id = rgr.recording_id
|
||||
LEFT JOIN release_groups rg ON rgr.release_group_id = rg.id
|
||||
LEFT JOIN cover_art ca ON rg.cover_art_id = ca.id
|
||||
WHERE pt.playlist_id = ?
|
||||
ORDER BY pt.position;
|
||||
```
|
||||
|
||||
d) **`GetAllPlaylistTracksWithMetadata`** — Same LEFT JOIN and phantom fallback pattern, without WHERE clause.
|
||||
|
||||
e) **`IsTrackInPlaylist`** — Change JOIN to LEFT JOIN (audio_file_id may be NULL for phantom tracks).
|
||||
|
||||
f) **`RemovePlaylistTrackByPath`** — Change subquery JOIN to handle nullable audio_file_id.
|
||||
|
||||
g) **`GetPlaylistTrackFilePaths`** — Change to LEFT JOIN, filter out NULLs:
|
||||
```sql
|
||||
-- name: GetPlaylistTrackFilePaths :many
|
||||
SELECT COALESCE(af.file_path, '') AS file_path
|
||||
FROM playlist_tracks pt
|
||||
LEFT JOIN audio_files af ON pt.audio_file_id = af.id
|
||||
WHERE pt.playlist_id = ? AND pt.audio_file_id IS NOT NULL
|
||||
ORDER BY pt.position;
|
||||
```
|
||||
|
||||
**3. Update `backend/database/sql/queries/audio_files.sql`:**
|
||||
|
||||
Add a query to get audio files filtered by library:
|
||||
```sql
|
||||
-- name: GetAudioFilesByLibrary :many
|
||||
SELECT * FROM audio_files WHERE library_id = ?;
|
||||
|
||||
-- name: CountAudioFilesByLibrary :one
|
||||
SELECT COUNT(*) AS count FROM audio_files WHERE library_id = ?;
|
||||
```
|
||||
|
||||
**4. Regenerate sqlc code:**
|
||||
|
||||
Run from `backend/database/`:
|
||||
```bash
|
||||
go generate ./...
|
||||
```
|
||||
|
||||
This regenerates all files in `sql/sqlcgen/` from the updated schemas and queries.
|
||||
|
||||
**5. Fix any compilation errors** in the generated code or in callers of the changed query signatures (particularly `AddPlaylistTrack` which now has 9 parameters instead of 3). Check all callers:
|
||||
- `backend/playlist/playlist.go` — calls `AddPlaylistTrack`. Update to pass phantom metadata.
|
||||
- Any other callers of changed queries.
|
||||
|
||||
For `AddPlaylistTrack` callers: pass the phantom metadata alongside the audio_file_id. The caller should resolve the metadata at insert time (eager population per user decision). Look at how `playlist.go` currently calls it and add the phantom fields. For now, populate phantom data from the track metadata that the caller already has available.
|
||||
|
||||
**IMPORTANT:** The playlist package's `AddTrack`/`AddTracks` methods need to resolve phantom metadata before inserting. Look at how `GetPlaylistTracksWithMetadata` resolves metadata — the same JOIN pattern should be used to fetch phantom data before insert. Or simpler: the caller already has the file path → look up metadata from DB → pass as phantom columns.
|
||||
|
||||
Create a helper query to resolve phantom metadata for a given audio_file_id:
|
||||
```sql
|
||||
-- name: GetTrackPhantomMetadata :one
|
||||
SELECT
|
||||
COALESCE(r.name, '') AS title,
|
||||
COALESCE(ac.text, '') AS artist,
|
||||
COALESCE(rg.name, '') AS album,
|
||||
af.length_milliseconds AS duration_ms,
|
||||
CAST(COALESCE(
|
||||
(SELECT GROUP_CONCAT(g.name, '||')
|
||||
FROM recording_genres rg_sub
|
||||
JOIN genres g ON rg_sub.genre_id = g.id
|
||||
WHERE rg_sub.recording_id = r.id),
|
||||
''
|
||||
) AS TEXT) AS genre,
|
||||
COALESCE(ca.file_path, '') AS cover_art_path
|
||||
FROM audio_files af
|
||||
LEFT JOIN recordings r ON af.recording_id = r.id
|
||||
LEFT JOIN artist_credit ac ON r.artist_credit_id = ac.id
|
||||
LEFT JOIN (
|
||||
SELECT recording_id, MIN(release_group_id) AS release_group_id
|
||||
FROM release_group_recordings
|
||||
GROUP BY recording_id
|
||||
) rgr ON r.id = rgr.recording_id
|
||||
LEFT JOIN release_groups rg ON rgr.release_group_id = rg.id
|
||||
LEFT JOIN cover_art ca ON rg.cover_art_id = ca.id
|
||||
WHERE af.id = ?;
|
||||
```
|
||||
|
||||
Add this to `playlists.sql`.
|
||||
|
||||
After regenerating, verify compilation:
|
||||
```bash
|
||||
cd backend && go build ./...
|
||||
```
|
||||
|
||||
Fix any broken callers of `AddPlaylistTrack` — the signature change from 3 args to 9 args will cause compile errors in the playlist package. Update each caller to:
|
||||
1. Look up phantom metadata via `GetTrackPhantomMetadata` query
|
||||
2. Pass all 9 params to `AddPlaylistTrack`

Write integration tests that verify migration 6 works correctly on both fresh and existing databases. Also update `NewTestDB` for the new schema.
|
||||
|
||||
**1. Update `testhelper.go`:**
|
||||
|
||||
The `NewTestDB` helper runs all schemas + migrations. Since migration 6 reads a TOML config file, and the test helper uses `:memory:` database with no file path, the migration will skip the TOML reading (existingDir = ""). The test helper needs to handle the updated `runMigrations` signature that now takes `dbPath`:
|
||||
|
||||
```go
|
||||
// Pass empty string for dbPath — in-memory DBs don't need backup.
|
||||
if err := runMigrations(ctx, db, slog.Default(), ""); err != nil {
|
||||
t.Fatalf("could not run migrations: %v", err)
|
||||
}
|
||||
```
|
||||
|
||||
The backup function should no-op when dbPath is empty. Verify this is handled in the migration 6 code (Plan 01 should have handled it — if not, add a guard).
|
||||
|
||||
Also add a `NewTestDBWithLibrary` helper that creates a test DB with a pre-populated library, useful for tests in other packages:
|
||||
|
||||
```go
|
||||
// NewTestDBWithLibrary returns a test DB with a library row pre-inserted.
|
||||
// Returns the DB and the library ID.
|
||||
func NewTestDBWithLibrary(t *testing.T, name, path string) (*DB, int64) {
|
||||
t.Helper()
|
||||
db := NewTestDB(t)
|
||||
lib, err := db.Queries.CreateLibrary(db.Ctx, sqlcgen.CreateLibraryParams{
|
||||
Name: name,
|
||||
Path: path,
|
||||
})
|
||||
if err != nil {
|
||||
t.Fatalf("could not create test library: %v", err)
|
||||
}
|
||||
return db, lib.ID
|
||||
}
|
||||
```
|
||||
|
||||
**2. Create/update `database_test.go`:**
|
||||
|
||||
Write these test cases:
|
||||
|
||||
a) **TestMigration6FreshDB** — Verify that a fresh database (no prior data) creates all expected tables including libraries, and that the schema matches expectations:
|
||||
```go
|
||||
func TestMigration6FreshDB(t *testing.T) {
|
||||
db := NewTestDB(t)
|
||||
|
||||
// Verify libraries table exists
|
||||
var tableCount int
|
||||
err := db.QueryRow("SELECT COUNT(*) FROM sqlite_master WHERE type='table' AND name='libraries'").Scan(&tableCount)
|
||||
// assert tableCount == 1
|
||||
|
||||
// Verify audio_files has library_id column
|
||||
// Query PRAGMA table_info(audio_files), check for library_id
|
||||
|
||||
// Verify playlist_tracks has phantom columns and nullable audio_file_id
|
||||
// Query PRAGMA table_info(playlist_tracks), check columns
|
||||
|
||||
// Verify track_metadata VIEW includes library_id
|
||||
// Query PRAGMA table_info(track_metadata), check for library_id — wait, VIEWs don't work with table_info
|
||||
// Instead: SELECT sql FROM sqlite_master WHERE name='track_metadata'
|
||||
// Assert contains 'library_id'
|
||||
|
||||
// Verify user_version is current (>= 6)
|
||||
var version int
|
||||
err = db.QueryRow("PRAGMA user_version").Scan(&version)
|
||||
// assert version >= 6
|
||||
|
||||
// Verify libraries table is empty on fresh DB
|
||||
count, err := db.Queries.CountLibraries(db.Ctx)
|
||||
// assert count == 0
|
||||
}
|
||||
```
|
||||
|
||||
b) **TestMigration6LibraryQueries** — Verify CRUD operations on libraries table work:
|
||||
```go
|
||||
func TestMigration6LibraryQueries(t *testing.T) {
|
||||
db := NewTestDB(t)
|
||||
|
||||
// Create a library
|
||||
lib, err := db.Queries.CreateLibrary(db.Ctx, sqlcgen.CreateLibraryParams{
|
||||
Name: "Music",
|
||||
Path: "/home/user/Music",
|
||||
})
|
||||
// assert lib.Name == "Music", lib.Path == "/home/user/Music"
|
||||
// assert lib.ID > 0
|
||||
|
||||
// Get by ID
|
||||
got, err := db.Queries.GetLibrary(db.Ctx, lib.ID)
|
||||
// assert got matches lib
|
||||
|
||||
// Get by path
|
||||
gotByPath, err := db.Queries.GetLibraryByPath(db.Ctx, "/home/user/Music")
|
||||
// assert gotByPath matches lib
|
||||
|
||||
// Unique path constraint
|
||||
_, err = db.Queries.CreateLibrary(db.Ctx, sqlcgen.CreateLibraryParams{
|
||||
Name: "Duplicate",
|
||||
Path: "/home/user/Music",
|
||||
})
|
||||
// assert IsUniqueViolation(err)
|
||||
|
||||
// List libraries
|
||||
libs, err := db.Queries.GetAllLibraries(db.Ctx)
|
||||
// assert len(libs) == 1
|
||||
|
||||
// Update name
|
||||
err = db.Queries.UpdateLibraryName(db.Ctx, sqlcgen.UpdateLibraryNameParams{
|
||||
Name: "My Music",
|
||||
ID: lib.ID,
|
||||
})
|
||||
// Verify name changed
|
||||
|
||||
// Delete
|
||||
err = db.Queries.DeleteLibrary(db.Ctx, lib.ID)
|
||||
count, _ := db.Queries.CountLibraries(db.Ctx)
|
||||
// assert count == 0
|
||||
}
|
||||
```
|
||||
|
||||
c) **TestMigration6PhantomPlaylistTracks** — Verify playlist tracks work with phantom columns:
|
||||
```go
|
||||
func TestMigration6PhantomPlaylistTracks(t *testing.T) {
|
||||
db, libID := NewTestDBWithLibrary(t, "Test", "/test/music")
|
||||
|
||||
// Create prerequisite data: file_type, recording, audio_file
|
||||
// (use pattern from existing seedSearchData or seedAudioFiles)
|
||||
|
||||
// Create playlist
|
||||
playlist, _ := db.Queries.CreatePlaylist(db.Ctx, "Test Playlist")
|
||||
|
||||
// Add track with phantom metadata (eager population)
|
||||
track, err := db.Queries.AddPlaylistTrack(db.Ctx, sqlcgen.AddPlaylistTrackParams{
|
||||
PlaylistID: playlist.ID,
|
||||
AudioFileID: sql.NullInt64{Int64: audioFileID, Valid: true},
|
||||
Position: 0,
|
||||
PhantomTitle: sql.NullString{String: "Test Song", Valid: true},
|
||||
PhantomArtist: sql.NullString{String: "Test Artist", Valid: true},
|
||||
PhantomAlbum: sql.NullString{String: "Test Album", Valid: true},
|
||||
PhantomDurationMs: sql.NullInt64{Int64: 180000, Valid: true},
|
||||
PhantomGenre: sql.NullString{String: "Rock", Valid: true},
|
||||
PhantomCoverArtPath: sql.NullString{String: "", Valid: false},
|
||||
})
|
||||
// assert track created
|
||||
|
||||
// Delete the audio_file — should SET NULL on audio_file_id
|
||||
// (not CASCADE delete the playlist_track)
|
||||
_, err = db.ExecContext("DELETE FROM audio_files WHERE id = ?", audioFileID)
|
||||
|
||||
// Verify playlist track still exists with NULL audio_file_id
|
||||
tracks, _ := db.Queries.GetPlaylistTracksWithMetadata(db.Ctx, playlist.ID)
|
||||
// assert len(tracks) == 1
|
||||
// assert tracks[0].AudioFileID is NULL/invalid
|
||||
// assert tracks[0].Title == "Test Song" (from phantom)
|
||||
// assert tracks[0].IsPhantom == 1
|
||||
}
|
||||
```
|
||||
|
||||
d) **TestMigration6AudioFilesLibraryFK** — Verify library_id FK enforcement:
|
||||
```go
|
||||
func TestMigration6AudioFilesLibraryFK(t *testing.T) {
|
||||
db, libID := NewTestDBWithLibrary(t, "Test", "/test")
|
||||
|
||||
// Insert audio_file with valid library_id — should succeed
|
||||
// Insert audio_file with invalid library_id (999) — should fail FK check
|
||||
|
||||
// Count files by library
|
||||
count, _ := db.Queries.CountAudioFilesByLibrary(db.Ctx, libID)
|
||||
// assert count == 1
|
||||
}
|
||||
```
|
||||
|
||||
e) **TestMigration6TrackMetadataViewHasLibraryID** — Verify the VIEW includes library_id:

**Test patterns to follow:**
|

- Use `NewTestDB(t)` or `NewTestDBWithLibrary(t, ...)` for setup
|

- Use `t.Helper()` in helpers
|

- Use `t.Context()` — NOT `context.Background()`
|
||||
- Table-driven subtests where appropriate
|
||||
- Use `database.IsUniqueViolation(err)` for constraint checks
|
||||
- Follow existing test naming convention: `Test{Feature}{Behavior}`

# Phase 10 Plan 2: sqlc Queries & Migration Tests Summary
|
||||
|
||||
**Library CRUD queries, phantom-aware playlist queries with LEFT JOIN + COALESCE fallback, and 5 migration 6 integration tests**
|
||||
|
||||
## Performance
|
||||
|
||||
- **Duration:** 5 min
|
||||
- **Started:** 2026-03-09T13:45:05Z
|
||||
- **Completed:** 2026-03-09T13:50:34Z
|
||||
- **Tasks:** 2
|
||||
- **Files modified:** 9
|
||||
|
||||
## Accomplishments
|
||||
- Created 7 library CRUD queries (create, get, get-by-path, list, update, delete, count) with sqlc-generated Go code
|
||||
- Updated all playlist track queries to use LEFT JOIN for nullable audio_file_id, with COALESCE fallback chain from live metadata to phantom metadata
|
||||
- Added GetTrackPhantomMetadata helper query for eager phantom population at insert time
|
||||
- Added is_phantom computed column to GetPlaylistTracksWithMetadata and GetAllPlaylistTracksWithMetadata
|
||||
- Added GetAudioFilesByLibrary and CountAudioFilesByLibrary queries
|
||||
- Created 5 comprehensive migration 6 integration tests covering fresh DB, CRUD, phantom tracks, FK enforcement, and VIEW validation
|
||||
- Added NewTestDBWithLibrary helper for downstream test usage
|
||||
|
||||
## Task Commits
|
||||
|
||||
Each task was committed atomically:
|
||||
|
||||
1. **Task 1: Add sqlc queries for libraries and update playlist queries** - `02548dd` (feat)
|
||||
2. **Task 2: Migration integration tests and NewTestDB update** - `bc15189` (feat)
|
||||
|
||||
## Files Created/Modified
|
||||
- `backend/database/sql/queries/libraries.sql` - 7 CRUD queries for libraries table
|
||||
- `backend/database/sql/queries/playlists.sql` - Updated with phantom support, LEFT JOINs, GetTrackPhantomMetadata
|
||||
- `backend/database/sql/queries/audio_files.sql` - Added GetAudioFilesByLibrary, CountAudioFilesByLibrary
|
||||
- `backend/database/sql/sqlcgen/libraries.sql.go` - Generated Go code for library queries
|
||||
- `backend/database/sql/sqlcgen/playlists.sql.go` - Regenerated with phantom columns, is_phantom, LEFT JOINs
|
||||
- `backend/database/sql/sqlcgen/audio_files.sql.go` - Regenerated with library filter queries
|
||||
- `backend/database/database_test.go` - 5 migration 6 integration tests
|
||||
- `backend/database/testhelper.go` - Added NewTestDBWithLibrary helper
|
||||
|
||||
## Decisions Made
|
||||
- COALESCE fallback chain: live data → phantom data → empty string ensures callers always get usable values regardless of whether a track is phantom or not
|
||||
- Added `is_phantom` as a computed column (`CASE WHEN pt.audio_file_id IS NULL THEN 1 ELSE 0 END`) to eliminate null-checking logic in callers
|
||||
- GetPlaylistTrackFilePaths now filters `WHERE audio_file_id IS NOT NULL` to exclude phantom tracks from file path lists
|
||||
|
||||
## Deviations from Plan
|
||||
|
||||
### Auto-fixed Issues
|
||||
|
||||
**1. [Rule 1 - Bug] Fixed NewTestDBWithLibrary path collision with sentinel library**
|
||||
- **Found during:** Task 2 (migration tests)
|
||||
- **Issue:** Tests using `NewTestDBWithLibrary(t, "Test", "/test")` collided with the sentinel library at `(0, 'Test', '/test')` from NewTestDB, causing UNIQUE constraint violation
|
||||
- **Fix:** Changed test paths to unique values (`/test/music`, `/test/fk-lib`, `/test/view-lib`) to avoid collision with sentinel
|
||||
- **Files modified:** backend/database/database_test.go
|
||||
- **Verification:** All 5 TestMigration6 tests pass
|
||||
- **Committed in:** bc15189 (Task 2 commit)
|
||||
|
||||
---
|
||||
|
||||
**Total deviations:** 1 auto-fixed (1 bug)
|
||||
**Impact on plan:** Minor path collision fix in tests. No scope creep.
|
||||
|
||||
## Issues Encountered
|
||||
None
|
||||
|
||||
## User Setup Required
|
||||
None - no external service configuration required.
|
||||
|
||||
## Next Phase Readiness
|
||||
- Phase 10 complete: schema files, migration 6, sqlc queries, and migration tests all in place
|
||||
- Ready for Phase 11 (per-library scan pipeline) — libraries table and library_id queries available
|
||||
- Ready for Phase 12 (library CRUD API) — all 7 library queries generated and tested
|
||||
- Ready for Phase 13 (library views & phantom tracks) — phantom metadata queries with is_phantom column available

# Phase 10: Schema & Migration - Context
|
||||
|
||||
**Gathered:** 2026-03-09
|
||||
**Status:** Ready for planning
|
||||
|
||||
<domain>
|
||||
## Phase Boundary
|
||||
|
||||
The database supports multiple libraries and phantom tracks — existing users upgrade seamlessly. Delivers: `libraries` table, `audio_files.library_id` FK, `playlist_tracks` phantom metadata columns, config migration from TOML to SQLite, and atomic migration guarantees. No UI, no CRUD API, no scan pipeline changes — just schema and migration.
|
||||
|
||||
Requirements: DATA-01, DATA-04, LIB-04, LIB-05, LSCAN-05
|
||||
|
||||
</domain>
|
||||
|
||||
<decisions>
|
||||
## Implementation Decisions
|
||||
|
||||
### Migration experience
|
||||
- Silent auto-migrate on startup — no user interaction, no progress indicator, no confirmation dialog
|
||||
- Migration runs automatically when the app detects the schema version is behind
|
||||
- On migration failure: show error dialog and refuse to start — no degraded/read-only mode
|
||||
- Automatic database backup before migration runs (copy .db file before any schema changes)
|
||||
- Schema version tracked via integer (SQLite `user_version` pragma or schema_version table) — app checks on startup, runs pending migrations sequentially
|
||||
|
||||
### Default library identity
|
||||
- Migrated library name derived from the directory name (e.g., `/home/user/Music` becomes "Music")
|
||||
- `music_directory` key removed from TOML config after successful migration — libraries table is the sole source of truth
|
||||
- Old config key ignored if still present (no crash on stale config)
|
||||
- Fresh installs start with an empty libraries table — no default library auto-created, user adds their first library when they want to scan
|
||||
- Libraries table is minimal: name, path, created_at — no scan metadata columns yet (Phase 11 can add those)
|
||||
|
||||
### Phantom track schema
|
||||
- Rich cached metadata on `playlist_tracks`: title, artist, album, duration, genre, cover art path
|
||||
- Eager population: metadata columns filled on every playlist_tracks insert (not lazily on library removal)
|
||||
- Phantom tracks identified by NULL `audio_file_id` — no separate `is_phantom` boolean column needed
|
||||
- Migration adds new columns via ALTER TABLE ADD COLUMN (not table rebuild) — existing playlist_tracks rows get NULL metadata columns, backfilled from audio_files data
|
||||
|
||||
### Migration rollback strategy
|
||||
- One-way migration — downgrade to pre-multi-library versions is unsupported
|
||||
- Pre-migration backup is the user's safety net for rollback
|
||||
- Backup file naming is timestamp-based (e.g., `yellowjacket.db.bak.20260309`) — multiple backups can coexist
|
||||
- No automatic backup cleanup — user manages old backup files
|
||||
- Migration events (start, success, backup path, errors) logged at INFO level to standard app log
|
||||
|
||||
### Claude's Discretion
|
||||
- Exact column types and constraints for the libraries table
|
||||
- Index strategy for library_id FK on audio_files
|
||||
- Whether to use SQLite `user_version` pragma vs a dedicated schema_version table
|
||||
- Migration transaction boundaries (single transaction vs per-step)
|
||||
- Backfill query strategy for populating phantom metadata on existing playlist_tracks rows

| LIB-05 | 10-02 | Existing single-directory config is migrated seamlessly to the libraries table on first run after upgrade | ✓ SATISFIED | `readLibraryDirFromTOML` reads existing config; `migration6MultiLibrary` step 5 creates default library; `removeLibraryDirFromTOML` cleans up config |
|
||||
|
||||
No orphaned requirements found — all 5 requirement IDs (DATA-01, DATA-04, LIB-04, LIB-05, LSCAN-05) are claimed by plans and satisfied.

### Anti-Patterns Found
|
||||
|
||||
| File | Line | Pattern | Severity | Impact |
|
||||
|------|------|---------|----------|--------|
|
||||
| — | — | — | — | No anti-patterns found |
|

|
||||
No TODO/FIXME/PLACEHOLDER/HACK/XXX markers found in any database package files. No empty implementations or stub patterns detected.
|

|
||||
### Human Verification Required
|
||||
|
||||
### 1. Migration on Real v5 Database
|
||||
|
||||
**Test:** Run the application against a real existing v5 database with audio files and playlists
|
||||
**Expected:** Migration 6 runs silently — backup file created, libraries table populated from TOML config, all audio_files get correct library_id, playlist_tracks rebuilt with phantom metadata backfilled, app starts normally
|
||||
**Why human:** In-memory test DBs skip backup and TOML reading; real filesystem paths, file permissions, and TOML parsing edge cases can only be verified with a real database
|
||||
|
||||
### 2. TOML Config Cleanup
|
||||
|
||||
**Test:** After migration, check that `config.toml` no longer has `DirectoryPath` under `[Library]` section
|
||||
**Expected:** DirectoryPath removed, other config sections preserved intact
|
||||
**Why human:** TOML marshaling with `map[string]any` may reorder keys or change formatting — verify config file is still valid and readable
|
||||
|
||||
### Gaps Summary
|
||||
|
||||
No gaps found. All 14 must-have truths verified, all 9 artifacts exist and are substantive, all 4 key links are wired, and all 5 requirements are satisfied. The build compiles cleanly (`go build ./...`), all tests pass (`go test ./backend/database/... ./backend/playlist/...`), and no anti-patterns were detected.
|
||||
|
||||
The migration implementation is thorough: 14-step migration function with SAFETY comments, pre-migration backup, TOML config read/cleanup, table rebuild with FK OFF/ON wrapping, phantom metadata backfill, and VIEW recreation. The sqlc queries are properly generated with LEFT JOINs, COALESCE fallback chains, and is_phantom computed columns.
