CRITICAL FIXES:
- Encryption detection false positive (IsBackupEncrypted returned true for ALL files)
- 12 cmd.Wait() deadlocks fixed with channel-based context handling
- TUI timeout bugs: 60s->10min for safety checks, 15s->60s for DB listing
- diagnose.go timeouts: 60s->5min for tar/pg_restore operations

Implements cluster cleanup option for CLI (matches TUI functionality).
Features:
- --clean-cluster flag drops all user databases before restore
- Preserves system databases (postgres, template0, template1)
- Shows databases to be dropped in dry-run mode
- Requires --confirm for safety
- Warns user with 🔥 icon when enabled
- Can combine with --workdir for full disaster recovery
Use cases:
- Disaster recovery scenarios (clean slate restore)
- Prevent database conflicts during cluster restore
- Ensure consistent cluster state
Examples:
# Disaster recovery
dbbackup restore cluster backup.tar.gz --clean-cluster --confirm
# Combined with workdir
dbbackup restore cluster backup.tar.gz \
--clean-cluster \
--workdir /mnt/storage/restore_tmp \
--confirm
Chef's kiss backup tool! 👨🍳💋
Sanitized all production-specific paths:
- /u01/dba/restore_tmp → /mnt/storage/restore_tmp
- /u01/dba/dumps/ → /mnt/backups/
Changed in:
- cmd/restore.go: Help text and flag description
- internal/restore/safety.go: Error message tip
- README.md: All documentation examples
- bin/*: Rebuilt all platform binaries
This ensures no production environment paths are exposed in public code/docs.
Replaced actual production database names with generic examples:
- test00, teststablekc, keycloak, stabledc → myapp_production, myapp_analytics, users_db, inventory_db, reports_db
- Updated archive filenames to generic examples
- Changed dates to generic future dates
- Adjusted database counts (7 → 5)
- Modified file sizes to be more generic
This ensures no production-specific information is exposed in public documentation.
Completed TUI documentation with missing screens:
- Database Status & Health Check:
* Connection status with checkmark
* Database info (type, host, port, user, version)
* Backup directory location
* Database count
* Health status indicator
- Backup Archive Manager (List & Manage):
* Total archives and size summary
* Sortable table with filename, format, size, date
* Status indicators (✓ valid, ⚠ old, ✗ invalid)
* Cursor navigation
* Keyboard shortcuts for restore/verify/info/delete/refresh
All TUI screens now documented accurately!
Replaced outdated backup progress view with actual TUI implementation:
- Backup Execution (in progress):
* Shows type, database, duration
* Spinner animation with status message
* Cancel instruction
- Backup Completed (success):
* Completion status with checkmark
* Backup details (filename, size, location, databases)
* SHA-256 verification confirmed
* Return to menu instruction
Removed old progress bar style (45%, ETA, Speed) that's not in current TUI.
Now accurately reflects the actual backup execution screen.
Added missing TUI screen examples for restore operations:
- Restore Preview screen showing:
* Archive information (file, format, size, date)
* Cluster restore options with existing databases list
* Safety checks with status indicators (✓/✗/⚠)
* Cleanup warning when enabled
* Keyboard shortcuts
- Restore Progress screen showing:
* Current phase and status with spinner
* Database being restored with size
* Elapsed time
* Cancel instruction
Both screens match actual TUI implementation.
Enhanced documentation for --workdir flag:
- Added to Cluster Restore command reference section
- Added example to restore examples with clear "special case" comment
- Explained use case: VMs with small system disk but large NFS mounts
- Clarified it's NOT needed for standard deployments
- Prevents confusion about when to use this flag
Updated to match actual TUI implementation:
- Shows all 13 configuration fields with current values
- Includes database type cycling (PostgreSQL/MySQL/MariaDB)
- Shows Current Configuration summary section
- Displays keyboard shortcuts (↑/↓ navigate, Enter edit, 's' save, 'r' reset, 'q' menu)
- Matches screenshot appearance
The interactive menu display was outdated. Updated to match current implementation:
- Shows database engine switcher (PostgreSQL/MySQL/MariaDB)
- Lists all 13 menu options with separators
- Includes new features: Sample backup, Cluster operations, Active operations, History
- Matches actual TUI appearance from screenshots
Solves disk space issues on VMs with small system disks but large NFS mounts.
Use case:
- VM has small / partition (e.g., 7.8G with 2.3G used)
- Backup archive on NFS mount (e.g., /u01/dba with 140G free)
- Restore fails: "insufficient disk space: 74.7% used - need at least 4x archive size"
Solution:
- Added --workdir flag to restore cluster command
- Allows specifying alternative extraction directory
- Interactive confirmation required for safety
- Updated error messages with helpful tip
Example:
dbbackup restore cluster backup.tar.gz --workdir /u01/dba/restore_tmp --confirm
This is environmental, not a bug. Code working brilliantly! 👨🍳💋
