- Added 'Diagnose Backup File' as menu option in TUI
- Archive browser now supports 'diagnose' mode
- Allows users to run deep diagnosis on backups before restore
- Helps identify truncation/corruption issues in large backups
Features:
- restore diagnose command for backup file analysis
- Deep COPY block verification for truncated dump detection
- PGDMP signature and gzip integrity validation
- Detailed error reports with --save-debug-log flag
- Ring buffer stderr capture (prevents OOM on 2M+ errors)
- Error classification with actionable recommendations
TUI Enhancements:
- Automatic dump validity safety check before restore
- Press 'd' in archive browser to diagnose backups
- Press 'd' in restore preview for debug log toggle
- Debug logs saved to /tmp on failure when enabled
Documentation:
- Updated README with diagnose command and examples
- Updated CHANGELOG with full feature list
- Updated restore preview screenshots
Fixes Windows, OpenBSD, and NetBSD builds by extracting
EstimateBackupSize from disk_check.go (which has build tags
excluding those platforms) to a new estimate.go file.
Why wrap external tools when you can BE the tool?
New physical backup engines:
• MySQL Clone Plugin - native 8.0.17+ physical backup
• Filesystem Snapshots - LVM/ZFS/Btrfs orchestration
• Binlog Streaming - continuous backup with seconds RPO
• Parallel Cloud Upload - stream directly to S3, skip local disk
Smart engine selection automatically picks the optimal strategy based on:
- MySQL version and edition
- Available filesystem features
- Database size
- Cloud connectivity
Zero external dependencies. Single binary. Enterprise capabilities.
Commercial backup vendors: we need to talk.
- Add --dry-run/-n flag for backup commands with comprehensive preflight checks
- Database connectivity validation
- Required tools availability check
- Storage target and permissions verification
- Backup size estimation
- Encryption and cloud storage configuration validation
- Implement GFS (Grandfather-Father-Son) retention policies
- Daily/Weekly/Monthly/Yearly tier classification
- Configurable retention counts per tier
- Custom weekly day and monthly day settings
- ISO week handling for proper week boundaries
- Add notification system with SMTP and webhook support
- SMTP email notifications with TLS/STARTTLS
- Webhook HTTP notifications with HMAC-SHA256 signing
- Slack-compatible webhook payload format
- Event types: backup/restore started/completed/failed, cleanup, verify, PITR
- Configurable severity levels and retry logic
- Update README.md with documentation for all new features
- Add 'migrate cluster' command for full cluster migration
- Add 'migrate single' command for single database migration
- Support PostgreSQL and MySQL database migration
- Staged migration: backup from source → restore to target
- Pre-flight checks validate connectivity before execution
- Dry-run mode by default (--confirm to execute)
- Support for --clean, --keep-backup, --exclude options
- Parallel backup/restore with configurable jobs
- Automatic cleanup of temporary backup files
- Remove emoticons and bloated content
- Clean professional documentation
- Include all TUI screenshots
- Match actual application features
- Reduce from 1537 to ~380 lines
- The 'env GOOS=x GOARCH=y command' syntax fails on some systems
- Using 'export GOOS GOARCH' before go build for better compatibility
- Updated version to 3.1.0
- All 10 platform builds now succeed
- Fix format detection to read database_type from .meta.json metadata file
- Add ensureMySQLDatabaseExists() for MySQL/MariaDB database creation
- Route database creation to correct implementation based on db type
- Add TUI auto-forward in auto-confirm mode (no input required for debugging)
- All TUI components now exit automatically when --auto-confirm is set
- Fix status view to skip loading in auto-confirm mode
- Add WithField and WithFields methods to NullLogger to implement Logger interface
- Change MenuModel to use pointer receivers to avoid copying sync.Once
- Add .golangci.yml with minimal linters (govet, ineffassign)
- Run gofmt -s and goimports on all files to fix formatting
- Disable fieldalignment and copylocks checks in govet
The format detection now returns PostgreSQL Dump format for .dump files
when the file cannot be opened (e.g., when just checking filename pattern),
instead of falling back to SQL format.
This fixes the test that passes just a filename string without an actual file.
NullLogger now fully implements the Logger interface by adding:
- WithField(key string, value interface{}) Logger
- WithFields(fields map[string]interface{}) Logger
Both methods return the same NullLogger instance (no-op behavior),
which is appropriate for a null logger used in testing.
