This commit introduces a worker-based architecture for managing chat history to prevent blocking the main VS Code thread. It enhances the AgentService with asynchronous chat history operations using SQLite for persistent storage. - Implemented ChatHistoryWorker for non-blocking database operations - Integrated ChatHistoryWorker into AgentService for managing chat history - Added support for saving, retrieving, clearing, and adding chat messages asynchronously - Implemented optimized retrieval of recent chat history with limit - Added background cleanup operations for old chat history across all agents - Included comprehensive tests for worker operations, concurrency, and error handling - Added documentation for the new architecture in
…Documentation Refactor ChatHistoryWorker to use an enum (ChatHistoryWorkerOperation) for operation types, improving type safety. Add comprehensive JSDoc-style comments to ChatHistoryWorker, detailing its purpose, architecture, and usage. Create new documentation files (SETTIMEOUT_EXPLANATION.md and WEBWORKER_BLOCKERS_VSCODE.md) to explain the rationale behind using setTimeout and the limitations of web workers in VS Code extensions.
- Integrates WASM SQLite for chat history storage via chat history worker. - Adds sql-wasm.wasm file. - Implements fallback mechanism to file storage for backward compatibility. - Optimizes recent chat history retrieval using the worker.
