- Implement context cleanup with sync.Once and io.Closer interface
- Add regex-based error classification for robust error handling
- Create ProcessManager with thread-safe process tracking
- Add disk space caching with 30s TTL for performance
- Implement metrics collection with structured logging
- Add config persistence (.dbbackup.conf) for directory-local settings
- Auto-save/auto-load configuration with --no-config and --no-save-config flags
- Successfully tested with 42GB d7030 database (35K large objects, 36min backup)
- All cross-platform builds working (9/10 platforms)
- Created internal/cleanup package for orphaned process management
- KillOrphanedProcesses(): Finds and kills pg_dump, pg_restore, gzip, pigz
- killProcessGroup(): Kills entire process groups (handles pipelines)
- Pass parent context through all TUI operations (backup/restore inherit cancellation)
- Menu cancel now kills all child processes before exit
- Fixed context chain: menu.ctx → backup/restore operations
- No more zombie processes when user quits TUI mid-operation
Context chain:
- signal.NotifyContext in main.go → menu.ctx
- menu.ctx → backup_exec.ctx, restore_exec.ctx
- Child contexts inherit cancellation via context.WithTimeout(parentCtx)
- All exec.CommandContext use proper parent context
Prevents: Orphaned pg_dump/pg_restore eating CPU/disk after TUI quit
- Removed workloadOption struct and workload-related fields from MenuModel
- Removed workload initialization and cursor tracking
- Removed keyboard handlers (Shift+←/→, 'w') for workload switching
- Removed workload selector display from main menu view
- Removed applyWorkloadSelection() function
- CPU workload type now only configurable via Configuration Settings
- Cleaner main menu focused on actions rather than configuration
Added interactive workload type selector similar to database type selector:
- Three workload options: Balanced | CPU-Intensive | I/O-Intensive
- Switch with Shift+←/→ arrows or 'w' key
- Automatically adjusts Jobs and DumpJobs based on selection:
* CPU-Intensive: More parallelism (2x physical cores)
* I/O-Intensive: Less parallelism (0.5x physical cores)
* Balanced: Standard parallelism (1x physical cores)
UI shows current selection with description:
- Balanced (General purpose)
- CPU-Intensive (More parallelism)
- I/O-Intensive (Less parallelism)
Real-time feedback shows adjusted Jobs/DumpJobs values.
Complements existing --cpu-workload CLI flag with interactive UX.
- PostgreSQL and MySQL support
- Interactive TUI with fixed menu navigation
- Line-by-line progress display
- CPU-aware parallel processing
- Cross-platform build support
- Configuration settings menu
- Silent mode for TUI operations
