- 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.
