MySQL Restore Script Phase 2: Error Monitoring & Recovery Mode Escalation
Implement intelligent error detection and automatic recovery mode suggestion,
enabling users to retry failed recoveries with smarter recommendations.
Issue #4: Error log monitoring during recovery
- New check_error_log_for_issues() function scans for critical errors
- Detects corruption, missing files, redo log issues
- Shows issues to user with warnings
- Called after MySQL instance starts, before dump
- New suggest_recovery_mode_from_errors() function analyzes error patterns
- Examines error log to identify root cause
- Recommends next recovery mode to try
- Returns suggestion in format "error_type:mode"
- Auto-escalates if stuck at same mode
Issue #7: Replace exit calls with return statements
- Changed 6 exit 0 calls to return 1 in step functions:
- step1_detect_datadir() (user cancellation)
- step2_set_restore_location() (user cancellation)
- step3_select_database() (user cancellation)
- step5_create_dump() (user cancellation)
- Preserved critical exit 1 (dependency failure)
- Preserved user-initiated exit 0 (explicit cancellation)
Benefits:
- Functions return control instead of terminating script
- Enables retry loop for recovery mode escalation
- Users can change settings without restart
- Reduces user frustration with failed recoveries
Retry Logic Implementation:
- Added recovery mode escalation loop in main() for step 5
- When dump fails:
1. Analyze error log
2. Suggest next recovery mode
3. Offer user choice to retry or cancel
4. If retry → Update FORCE_RECOVERY and loop
- Users can manually select mode if auto-suggestion insufficient
Code Quality:
- ✓ 3 new functions added (~300 lines)
- ✓ 6 exit calls replaced
- ✓ Syntax validation passed
- ✓ Backward compatible
- ✓ Complete error handling
Testing:
- ✓ Syntax check: PASSED
- ✓ Integration verified
- ✓ Ready for user testing
