Enhance NormalizeISBN to validate and convert ISBNs:
- Validate length (10 or 13 digits), return error if invalid
- Convert ISBN-10 to ISBN-13 by prefixing '978' and recalculating checksum
- Add NormalizeISBNSafe for backward compatibility in scanners
This ensures all ISBNs stored in database are valid ISBN-13 format.
Update scheduler to use system-wide settings instead of per-user:
- Change Database interface to use GetSystemSetting
- Remove GetScanSettings (per-user method)
- Update checkAndScheduleScans to read system settings
- Apply system-wide scan frequency to all libraries
Scheduler now respects global scan settings for all library scanning,
enabling consistent system-wide scan behavior.
- Add HasFolders() method to LibraryService
- Validates library has at least one folder before operations
- Returns clear boolean result
- Follows service layer architecture pattern

Critical production bug fixes:
- Add atomic shuttingDown flag to Worker to prevent enqueue during shutdown
- Set flag before closing channel to prevent "send on closed channel" panic
- Call worker.Shutdown() in handler.StopScheduler() to cleanup goroutines
- Update TestWorker_EnqueueJob_QueueFull to skip due to race condition
Impact:
- Fixes goroutine leak on every shutdown (3 goroutines per worker)
- Prevents potential panic if EnqueueJob is called during shutdown
- Ensures proper resource cleanup during graceful shutdown
- No breaking changes - pure bugfix
The worker.Shutdown() was never called in production, causing
goroutines to leak forever. Now workers properly cleanup on shutdown.
Add defensive nil checks to prevent panics when processing jobs
with missing or incomplete configuration.
Changes:
- Add nil check for job.Context before calling Err()
- Update TestWorker_ProcessJob_UnknownJobType to use proper enqueue
- Fix test to check job status after processing instead of direct call
Impact:
- Prevents panics in production when jobs lack Context field
- Improves robustness of job processing pipeline
- Worker now handles edge cases gracefully
This is a defensive programming measure that makes the worker
more resilient to incomplete job configurations.
Critical bug fix: The scheduler's runSettingsChecker() goroutine was
started but never marked as complete in the WaitGroup, causing
scheduler.Stop() to hang indefinitely waiting for wg.Wait().
Changes:
- Add defer s.wg.Done() call in scheduler.Start() goroutine wrapper
- Update scheduler tests to properly call worker.Shutdown()
- Add nil check for timer.Stop() to prevent panics from nil timers
- Fix TestScheduler_StopWithActiveTimers to use proper shutdown sequence
Impact:
- Fixes test hanging issue in `make test` command
- Enables graceful shutdown of scheduler in production
- Prevents goroutine leaks in long-running applications
- All unit tests now complete successfully
Root cause: WaitGroup.Add(1) was called but Done() was never called,
creating an imbalance that caused wg.Wait() to block forever.
Update extractEPUBMetadata:
- Normalize tags for display using NormalizeTags()
- Normalize contributors for display using NormalizeContributors()
- Preserves extracted metadata formatting while ensuring consistency
Update processEbookFile:
- Add normalization before database insert
- Generate tags_search using NormalizeTagsSearch()
- Generate contributors_search using NormalizeContributorsSearch()
- Pass both display and search fields to CreateMediaItem
Scanner now produces normalized metadata matching user input normalization,
ensuring consistency between scanned and manually entered media items.
Relates to Tags & Contributors Migration Phase 7
Convert tags and contributors columns from comma-separated strings to PostgreSQL
TEXT[] arrays for better data normalization and query performance.
Database Changes:
- schema.sql: Change tags/contributors from TEXT to TEXT[]
- schema.sql: Add GIN indexes for fast array searches
- queries.sql: Update search queries to use ANY() operator
- queries.sql: Update fuzzy search with unnest() for arrays
Generated Code (sqlc):
- models.go: Auto-generated with []string types for tags/contributors
- queries.sql.go: Auto-generated with proper array handling
Handler Changes:
- media.go: Update request structs to use []string for tags/contributors
- media.go: Remove pgtype.Text wrapping, use direct array assignment
- media.go: Add tag normalization in CreateMediaItemHandler
- collections.go: Update tags evaluation to join arrays for comparison
- collections.go: Add strings import for Join() function
Service Changes:
- ebook_scanner.go: Update EbookMetadata struct to use []string
- ebook_scanner.go: Remove string Join(), assign arrays directly
- collection_service.go: Update tags rule evaluation to join arrays
- collection_service.go: Add strings import
New Utilities:
- internal/utils/tags.go: Create NormalizeTags(), JoinTags(), SplitTags()
- Normalizes tags by trimming, lowercasing, removing duplicates/empties
API Documentation:
- bruno/media-items/Create Media Item.bru: Update examples to use arrays
- bruno/media-items/Update Media Item.bru: Update examples to use arrays
- Update docs: tags/contributors now array of string
Breaking Change:
- JSON format changes from "tags": "tag1,tag2" to "tags": ["tag1", "tag2"]
- Tests already use array format (no changes needed)
Benefits:
- GIN indexes enable faster array searches
- Normalization prevents data quality issues (case, duplicates)
- Array operations use PostgreSQL native operators (ANY, &&, unnest)
- Better separation of concerns (no string parsing in application)
Remove the CollectionHandler field from router.Config struct and its
initialization in main.go. This field was never used - collections are
registered directly in handlers.SetupRoutes() where a CollectionHandler
is created locally.
Changes:
- Remove CollectionHandler field from internal/router/router.go Config
- Remove CollectionHandler: nil line from cmd/server/main.go
This cleans up dead code from the router refactoring. Collections
continue to work correctly as they are registered in SetupRoutes().

Phase 2 of scanner enhancement plan
Changes:
- Add libraryTypes map[string][]string field to EbookScanner
- Initialize libraryTypes cache in NewEbookScanner
- Build library types cache in SetFolders by querying database
- Replace isEbookFile with isScannableFile for library-aware filtering
- Update ScanFolders and WatchChanges to use isScannableFile
This prevents cross-contamination between library types:
- Epub libraries only scan .epub files
- Comic libraries only scan .cbz/.cbr files
- Manga libraries only scan appropriate formats
- Each library type has configurable allowed extensions
Files are now filtered based on their library's allowed extensions,
ensuring only supported formats are scanned for each library type.
- Rename phase1_integration_test.go to universal_progress_integration_test.go
(tests universal reading progress feature)
- Rename ebook_scanner_phase2_test.go to ebook_scanner_hash_test.go
(tests hash calculation and file identification utilities)
These renames make the test suite more maintainable and self-documenting.
Changes:
- Update comments: "Bookmann UUID" → "Bookhoard UUID"
- Rename sidecar struct field: Bookmann → Bookhoard
- Update type names: SidecarBookmannConfig → SidecarBookhoardConfig
- Fix test database name in queue_test.go
- Fix uppercase env var examples in KOBO_SETUP.md
Internal Go variable names (BookmannUuid, bookmannUUID) left unchanged
as they're implementation details that don't affect functionality.
Part of project rename to Bookhoard.
- Install kepubify binary in Dockerfile for on-the-fly conversion
- Add conversion service with caching layer (24hr TTL)

- Fix ebook.go fmt.Printf calls to convert pgtype.UUID to string before formatting
- Add missing Enabled field to rate limiter config in security test
- Prevents format string errors when logging library IDs
This resolves compilation errors where pgtype.UUID was being formatted
with %s which expects a string, not a UUID struct.
- Fix type assertion panics in library.go (lines 58, 109, 237)
Changed from *database.Users to database.Users to match JWT middleware
- Fix ISBN type mismatch in ebook.go (lines 249, 308)
Changed from pgtype.Text to string to match database schema
