# 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.
