DatabaseManager.ts (new file): - Singleton pattern with auto-initialization - State management (INITIALIZING, INITIALIZED, FAILED) - Windows compatibility fixes (empty file detection, intMode: 'number') - Simplified waitForInitialization() logic 2. BaseService.ts: - Removed static initialize() and ensureInitialized() methods - Simplified database/rawClient getters to use DatabaseManager 3. Service classes (AgentService, SessionService, SessionMessageService): - Removed all initialize() methods - Removed all ensureInitialized() calls - Services now work out of the box 4. Main entry points (index.ts, server.ts): - Removed explicit database initialization calls - Database initializes automatically on first access Benefits: - Fixes Windows libsql crashes by removing dangerous retry logic - Simpler API - no need to remember to call initialize() - Better separation of concerns - Cleaner codebase with 36% less code 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com> * fix: wait for database initialization on app startup Issue: "Database is still initializing" error on startup Root cause: Synchronous database getter was called before async initialization completed Solution: - Explicitly wait for database initialization in main index.ts - Import DatabaseManager and call getDatabase() to ensure initialization is complete - This guarantees database is ready before any service methods are called Changes: - src/main/index.ts: Added explicit database initialization wait before API server check 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com> * refactor: use static import for getDatabaseManager - Move import to top of file for better code organization - Remove unnecessary dynamic import 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com> * refactor: streamline database access in service classes - Replaced direct database access with asynchronous calls to getDatabase() in various service classes (AgentService, SessionService, SessionMessageService). - Updated the main index.ts to utilize runAsyncFunction for API server initialization, ensuring proper handling of asynchronous database access. - Improved code organization and readability by consolidating database access logic. This change enhances the reliability of database interactions across the application and ensures that services are correctly initialized before use. * refactor: remove redundant logging in ApiServer initialization - Removed the logging statement for 'AgentService ready' during server initialization. - This change streamlines the startup process by eliminating unnecessary log entries. This update contributes to cleaner logs and improved readability during server startup. * refactor: change getDatabase method to synchronous return type - Updated the getDatabase method in DatabaseManager to return a synchronous LibSQLDatabase instance instead of a Promise. - This change simplifies the database access pattern, aligning with the current initialization logic. This refactor enhances code clarity and reduces unnecessary asynchronous handling in the database access layer. * refactor: simplify sessionMessageRepository by removing transaction handling - Removed transaction handling parameters from message persistence methods in sessionMessageRepository. - Updated database access to use a direct call to getDatabase() instead of passing a transaction client. - Streamlined the upsertMessage and persistExchange methods for improved clarity and reduced complexity. This refactor enhances code readability and simplifies the database interaction logic. --------- Co-authored-by: Claude <noreply@anthropic.com>	2025-11-22 09:12:11 +08:00
