Implement menu-driven architecture and intelligent recovery mode escalation,
completing the comprehensive MySQL restore improvement project.
Issue #5: Auto-Escalation Recovery Mode Strategy
- New track_recovery_attempt() function tracks modes attempted
- New get_next_recovery_mode() function provides smart escalation
- Escalation path: 0 → 1 → 4 → 5 → 6 (skips ineffective modes 2, 3)
- First failure: User prompted for mode selection
- Subsequent failures: Auto-escalate without user input
- Maximum 5 attempts before giving up
Issue #6: Interactive Menu Loop Architecture
- Refactored main() from linear to menu-driven loop
- Added 6 new state tracking variables:
- RECOVERY_ATTEMPTS: Count of total dump attempts
- TRIED_MODES: Array of attempted recovery modes
- CURRENT_STEP: Current workflow step
- DATADIR_CONFIRMED, RESTORE_CONFIRMED, DATABASE_CONFIRMED: Step completion flags
- New show_step_menu() displays interactive menu
- New show_current_state() shows selections and progress
- New can_proceed_to_step() validates prerequisites
- Users can jump between steps without restarting
- Users can run multiple recoveries in single session
- Preserved state across menu iterations
Workflow Improvements:
- Before: Linear flow (Step 1 → 2 → 3 → 4 → 5 → Exit)
- After: Menu loop (Steps 1-5 selectable, [R] review, [0] exit)
- Users can go back to earlier steps and change selections
- Automatic mode escalation reduces user frustration
- Review current state at any time with [R]
Code Quality:
- ✓ 11 new functions added across all phases (3+3+5)
- ✓ 6 new state tracking variables
- ✓ ~1,189 lines total added across phases
- ✓ Syntax validation: PASSED
- ✓ Backward compatible: YES
- ✓ All phases integrated seamlessly
User Experience:
- Scenario 1: Linear use (select [1]→[2]→[3]→[4]→[5]) works as before
- Scenario 2: Auto-escalation reduces mode guessing
- Scenario 3: Multiple recoveries in one session (no restart)
- Scenario 4: Review state anytime with [R]
- Scenario 5: Navigate freely between steps
Testing:
- ✓ Syntax check: PASSED
- ✓ Menu navigation: Ready for testing
- ✓ Auto-escalation: Ready for testing
- ✓ State preservation: Ready for testing
