From 1910b96112bc20dd555682ceadfcb42f4ad00bf6 Mon Sep 17 00:00:00 2001 From: nioasoft Date: Fri, 23 Jan 2026 23:09:39 +0200 Subject: [PATCH 01/14] fix: add robust SQLite connection handling to prevent database corruption - Add WAL mode, busy timeout (30s), and retry logic for all SQLite connections - Create get_robust_connection() and robust_db_connection() context manager - Add execute_with_retry() with exponential backoff for transient errors - Add check_database_health() function for integrity verification - Update progress.py to use robust connections instead of raw sqlite3 - Add /api/projects/{name}/db-health endpoint for corruption diagnosis - Add DatabaseHealth schema for health check responses Fixes database corruption issues caused by concurrent access from multiple processes (MCP server, FastAPI server, progress tracking).
