Peter Wood 2bc9e91229 Refactor Plex Database Repair Logic

- Created a centralized database repair script (`plex-database-repair.sh`) to handle all database integrity checks and repairs for Plex Media Server.
- Updated the main Plex management script (`plex.sh`) to integrate the new repair functionality and fixed Unicode/ASCII display issues.
- Refactored the backup script (`backup-plex.sh`) to remove duplicate repair functions and ensure it utilizes the new repair script.
- Conducted thorough code validation and functional testing to ensure all scripts operate correctly with the new changes.
- Enhanced documentation for the new repair script, detailing usage, features, and integration points with other scripts.
- Fixed critical bugs related to WAL file handling and corrected typos in script options.

Plex Database Repair Refactoring - Completion Summary

Task Description

Refactor Plex Media Server management scripts to centralize database repair logic in a shared script (plex-database-repair.sh), remove duplicate/legacy repair logic from other scripts, and fix Unicode/ASCII display issues.

Completed Work

✅ 1. 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. Documentation

File: /home/acedanger/shell/docs/plex-database-repair.md
Content: Complete documentation of the shared repair script usage and features

Key Benefits Achieved

1. Code Deduplication

Eliminated duplicate repair logic across multiple scripts
Centralized repair strategies in single, well-tested script
Reduced maintenance burden and potential for inconsistencies

2. Improved Maintainability

All repair logic in one place for easier updates
Consistent repair behavior across all scripts
Single source of truth for database repair procedures

3. Enhanced User Experience

Fixed Unicode/ASCII display issues
Consistent repair interface across scripts
Clear command-line interface for repair operations

4. Better Error Handling

Centralized error handling and logging
Consistent return codes across scripts
Proper file ownership correction after repairs

5. Preserved Functionality

All existing backup and management functionality maintained
Backward compatibility preserved
No breaking changes to existing workflows

Files Modified

Created: /home/acedanger/shell/plex/plex-database-repair.sh
Updated: /home/acedanger/shell/plex/plex.sh
Updated: /home/acedanger/shell/plex/backup-plex.sh
Created: /home/acedanger/shell/docs/plex-database-repair.md

Critical Bug Fixes

Restored missing handle_wal_files() function - Critical for backup WAL operations
Fixed typo in --disable-auto-repair option - Was setting incorrect value
Fixed Unicode display issues - Proper ASCII character usage in plex.sh
Corrected function references - All calls now use shared repair script

Verification Status

✅ All scripts pass syntax validation
✅ Help systems functioning correctly
✅ Database repair integration working
✅ Backup script operations successful
✅ WAL file handling restored
✅ No orphaned function references
✅ All error handling preserved

Final State

The refactoring is complete and fully functional. All Plex management scripts now use the centralized database repair system while maintaining their individual responsibilities:

plex.sh: Service management and user interface
backup-plex.sh: Backup operations with integrity checking
plex-database-repair.sh: Specialized database repair operations

The system is ready for production use with improved maintainability and reduced code duplication.
