- Delete scheduler.go and scheduler_test.go (no longer needed)
- Simplify App struct by removing Handler interface dependency
- Remove StartScheduler/StopScheduler from app lifecycle
- Update main.go to not pass handler to app constructor
- Remove scheduler mock from app tests, simplify test coverage
- Add libraryService dependency to CollectionHandler and OPDSHandler for centralized path resolution
- Create internal/utils/mediaurl.go with ResolveMediaURL() function as single source of truth
- Update GetMediaItem and ListMediaItems handlers to return resolved URLs in API responses
- Update collection handlers (GetCollection, TestRules, PreviewCollection) to use resolved cover URLs
- Update progress handler (GetAllProgress) to use resolved cover URLs
- Add library_id to GetCollectionItems SQL query to enable URL resolution
- Refactor media scanner to store relative paths instead of absolute filesystem paths
- Add ResolveMediaPath() to LibraryService for resolving relative paths to absolute paths
- Add ServeFile endpoint at /uploads/library-:id/* for authenticated file serving
- Add MimeTypes map to library_service.go for consistent MIME type handling
- Update DownloadBook handler to use resolved filesystem paths

This change enables the application to work with relative paths stored in the
database, making it portable across different server environments while
maintaining backward compatibility with existing absolute paths.
Add DashboardService and DashboardHandler to application configuration:
Router Config Updates (internal/router/router.go):
- Add services import for DashboardService type
- Add DashboardService field to Config struct
- DashboardService: Used by SSR routes in frontend.go for data fetching
- DashboardHandler: Used by API routes in dashboard.go for JSON endpoints
Server Initialization (cmd/server/main.go):
- Create dashboardService instance using services.NewDashboardService(queries)
- Keep dashboardHandler creation (already exists from Phase 4)
- Add DashboardService to routerConfig
- Both services now available for dependency injection
Test Helpers (cmd/server/tests/test_helpers.go):
- Create dashboardService instance for testing
- Create dashboardHandler instance for testing
- Add both DashboardService and DashboardHandler to routerConfig
- Ensures test environment matches production setup
Architecture Rationale:
- DashboardService: Service layer with business logic (reusable by SSR, mobile)
- DashboardHandler: HTTP handler layer (JSON API endpoints)
- Separation allows SSR templates to call service directly
- API routes use handler for proper HTTP response handling
- Mobile apps can use API endpoints via DashboardHandler
All three files updated consistently for complete integration.
Create dashboardHandler instance and add to router config:
- Initialize dashboardHandler using handlers.NewDashboardHandler(queries)
- Add dashboardHandler to router.Config for route registration
- All dashboard routes are now available at /api/dashboard/*
- Add LibraryTestData struct to TestDeviceSetup
- Implement CreateLibrary() for proper library creation in tests
- Implement CreateCollection() for test collection support
- Improve test isolation with dedicated library creation
This provides a more robust foundation for integration tests that need
proper library management support.
- Add schema initialization call after database connection
- Initialize schema before handler creation
- Fatal on failure (schema is critical for app to function)
- Clear log messages show initialization progress
Server startup flow:
1. Load config
2. Connect to database
3. Initialize schema (NEW - ensures all tables/functions exist)
4. Create handlers and services
5. Start server
Add SystemSettingsHandler initialization in main.go:
- Create systemSettingsHandler instance with queries
- Add to router.Config for route registration
- Properly wired with existing dependencies
This enables the system settings endpoints to be registered and functional.
- Check library has folders before creating media items
- Return HTTP 400 with clear error message if no folders
- Proper error code (400) instead of generic 500
- Improved user feedback for invalid operations
- Inject LibraryService into MediaHandler
Fixes: TestCollectionsBulkOperations HTTP 500 errors

Critical fixes to prevent goroutine leaks during application shutdown:
1. Sync Queue Processor:
- Changed StartCleanupTask() to return context.CancelFunc
- Modified to accept and watch cancellable context
- Added queue context/cancel to Handler struct
- Created StartBackgroundTasks() method for main handler instance
- Cancel queue processor during shutdown in StopScheduler()
2. Connection Manager:
- Modified StartCleanupTask() to use cancellable context
- Returns cancel function that can be called during shutdown
- Goroutine now properly exits when context is cancelled
3. Handler Lifecycle:
- Added StartBackgroundTasks() to Handler
- Only main handler instance starts background goroutines
- Temporary handler instances (library/sync routes) don't start tasks
- StopScheduler() now properly shuts down all background goroutines
4. Router Integration:
- Updated SetupRoutes to accept queueProcessor parameter
- Main scanner handler starts background tasks after creation
- Library and sync route handlers don't start duplicate tasks
Impact:
- Fixes 2 major goroutine leaks (queue processor + connection cleanup)
- Application now properly shuts down all goroutines on exit
- No more resource leaks from long-running goroutines
- Test added to detect future goroutine regressions
Test: TestGoroutineCleanup verifies background services can be stopped.
- Create worker for background tasks (3 concurrent workers)
- Create CollectionHandler for collection endpoints
- Create MediaHandler with worker for media CRUD operations
- Create SearchHandler for query operations
- Create MatchingHandler for book matching/linking operations
- Update routerConfig to include new handlers instead of EbookHandler
All handlers properly initialized and passed to router package.
System is fully operational with new handler architecture.
This is Phase 6 of the ebook.go refactoring plan.
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 5: Application Lifecycle Management
Creates internal/app package for proper lifecycle management, signal
handling, and graceful shutdown of all services.
Changes:
- Create internal/app/app.go with App lifecycle manager
- Handles SIGINT, SIGTERM, SIGQUIT signals
- Graceful shutdown with 30-second timeout
- Manages HTTP server shutdown
- Manages scheduler start/stop
- Update cmd/server/main.go to use app lifecycle manager
- Replace defer-based cleanup with proper signal handling
- Server starts in background goroutine
- Blocks on app.Start() until shutdown signal
- Clean shutdown of all services
Benefits:
- Proper signal handling (Ctrl+C, kill, docker stop)
- Graceful shutdown prevents data corruption
- No more os.Exit(1) bypassing defer cleanup
- All services stopped in correct order
- Server stops accepting new connections first
- Then scheduler and background services stopped
Technical details:
- Uses sync.Mutex for shutdown safety
- Context with timeout for shutdown operations
- Channel-based coordination for shutdown completion
- Logs all lifecycle events for debugging
Fixes issue where e.Logger.Fatal() would call os.Exit(1)
immediately, skipping defer cleanup and causing unclean shutdown.
Phase 1 of scanner restoration plan
Changes:
- cmd/server/main.go: Capture ebookHandler from router.RegisterRoutes
- cmd/server/main.go: Start scheduler in background goroutine
- cmd/server/main.go: Defer StopScheduler() for graceful shutdown
- cmd/server/main.go: Start watch mode for all libraries after 2-second delay
- internal/router/router.go: Return ebookHandler from RegisterRoutes
This restores critical functionality that was removed during router refactor:
- Auto-scanning now works again
- Watch mode starts automatically for all libraries
- Graceful shutdown properly stops scheduler
Fixes issue where scheduler and watch mode were not starting on server boot.
Health check endpoint:
- Add /health endpoint that pings database with 2-second timeout
- Returns 200 when DB connected, 503 when unavailable
- Provides true end-to-end health verification
Frontend routes restoration (routes removed in c5f327b):
- Add public routes: /, /login, /register with smart auth detection
- Add redirect routes: /bookshelf, /dashboard
- Add admin routes: /admin, /admin/profile, /admin/library
- Add SSR routes: /api/devices-page, /api/conflicts-page
- Add 'FRONTEND ROUTES - DO NOT DELETE' comment block to prevent future removal
Docker Compose healthcheck:
- Update to use curl on /health endpoint (pg_isready not in Alpine)
- Add 10s start_period for app initialization
- Accurately reflects app + database health status
All changes maintain backward compatibility and existing API behavior.
- Add LibraryData type to templates/types.go
- Update bookshelf template to accept libraries parameter
- Render libraries server-side for faster initial page load
- Libraries now populated from server data instead of AJAX fetch
- JavaScript still uses API for dynamic content (bookshelf items)
- Update /bookshelf route to fetch libraries server-side before render
- Properly handle UUID and pgtype.Text conversions
- Maintain API endpoint compatibility for JavaScript calls
This improves initial page load performance while preserving
dynamic functionality via API calls.
Phase 4 part 1: Add search infrastructure
- Add SearchDoc struct and GenerateSearchIndex to docs handler
- Add stripHTML helper for plain text extraction
- Add ServeSearchIndex endpoint to http handler

- Table of contents for each page
- Breadcrumb navigation
- Full-text search (client-side JavaScript, API endpoint ready)
- Syntax highlighting for code blocks
- Mobile-friendly with hamburger menu
All documentation is served from /docs route, no authentication required.
Markdown files are rendered using goldmark with GFM extensions and syntax highlighting.
Implement real-time collection updates when books are added/removed:
Backend Changes:

- Updated constructor to accept ConnectionManager
- Updated all NewCollectionHandler() calls in ebook.go and main.go
- Added WebSocket broadcasts in AddBooks() handler
- Added WebSocket broadcasts in BulkRemoveBooks() handler
- Broadcasts collection_updated events with:

- book_ids: Array of affected book IDs
- count: Number of books changed
Frontend Changes:
- Added WebSocket connection in collections UI
- connectWebSocket() establishes connection to /ws/sync
- Listens for collection_updated events
- Shows toast notification on collection change
- Auto-reloads page after 1 second to show updated book list
- Auto-reconnect on disconnect (5s delay)
- Error handling for WebSocket failures
WebSocket Event Format:
{
"type": "collection_updated",
"timestamp": "2026-02-01T12:00:00Z",
"data": {
"collection_id": "uuid",
"action": "books_added",
"book_ids": ["uuid1", "uuid2"],
"count": 2
}
}
User Experience:
- When another user adds books to a collection, all connected clients see:
1. Toast notification: "Collection updated: books_added (2 books)"
2. Page auto-refreshes after 1 second
3. Updated book list displays
- Same for book removal
- Works across multiple browser tabs/devices
- No manual refresh needed
Technical Notes:
- Broadcasts to ALL connected WebSocket clients
- Client-side filtering by collection_id
- Existing progress/conflict broadcasts continue to work
- Connection manager handles broadcast distribution
Resolves Limitation #4: Real-time Collection Updates
Add SSR routes for collections, progress, and devices pages:
Progress Page (/api/progress):
- Fetches all user progress with device sync sources
- Maps device types to icons (Kobo, KOReader, Web, Mobile)
- Server-renders progress visualization with real data
Collections Pages (/api/collections):
- GET /collections: List all user collections with SSR
- GET /collections/🆔 Collection detail page with books SSR
- Fetches collection metadata and book listings
- Converts database models to template data structures
Helper Functions:
- getTemplateUserWithTheme: Fetches user with theme preference
- Proper error handling for missing data
All routes use JWT authentication and fetch data server-side
for better SEO and initial page load performance. Client-side
enhancements can be added via HTMX for interactive features.
