Created Shared Database Repair Script +- **File**: `/home/acedanger/shell/plex/plex-database-repair.sh` +- **Features**: + - Centralized database integrity checking and repair logic + - Multiple repair strategies (dump/restore, schema recreation, backup recovery) + - Proper WAL file handling for repair operations + - File ownership correction after repairs + - Command-line interface with check/repair/force-repair modes + - Comprehensive logging and error handling + +### ✅ 2. Updated Main Plex Management Script +- **File**: `/home/acedanger/shell/plex/plex.sh` +- **Changes**: + - Added `repair_plex()` function that uses the shared repair script + - Added user-facing `repair` command + - Fixed Unicode/ASCII display issues in output + - Integrated shared repair script for all database operations + - Maintained backward compatibility with existing functionality + +### ✅ 3. Refactored Backup Script +- **File**: `/home/acedanger/shell/plex/backup-plex.sh` +- **Major Changes**: + - **Removed duplicate repair functions**: + - `attempt_dump_restore()` + - `attempt_schema_recreation()` + - `attempt_backup_recovery()` + - `recover_table_data()` + - `cleanup_repair_files()` + - `handle_wal_files_for_repair()` + - `check_database_integrity_with_wal()` + - **Updated integrity and repair functions**: + - `check_database_integrity()` now calls shared repair script + - `repair_database()` now calls shared repair script + - **Fixed critical issue**: Restored missing `handle_wal_files()` function for backup operations + - **Fixed typo**: Corrected `AUTO_REPAIR=false.service` to `AUTO_REPAIR=false` + +### ✅ 4. Code Validation and Testing +- **Syntax validation**: All scripts pass `bash -n` syntax checks +- **Functional testing**: + - Help systems work correctly + - Database repair command integration successful + - Backup script operations functioning properly + - WAL file handling restored and working +- **Error checking**: No remaining references to removed functions + +### ✅ 5.
