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

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

Critical Bug Fixes

  1. Restored missing handle_wal_files() function - Critical for backup WAL operations
  2. Fixed typo in --disable-auto-repair option - Was setting incorrect value
  3. Fixed Unicode display issues - Proper ASCII character usage in plex.sh
  4. 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.
