- Increase timeout from 60 to 180 minutes for very large archives
- Use streaming pipes instead of buffering entire tar listing
- Only mark as corrupted for clear corruption signals (unexpected EOF, invalid gzip)
- Prevents false CORRUPTED errors on valid large archives
- CheckDiskSpace now uses GetEffectiveWorkDir() instead of BackupDir
- Dynamic timeout calculation based on file size:
- diagnoseClusterArchive: 5 + (GB/3) min, max 60 min
- verifyWithPgRestore: 5 + (GB/5) min, max 30 min
- DiagnoseClusterDumps: 10 + (GB/3) min, max 120 min
- TUI safety checks: 10 + (GB/5) min, max 120 min
- Timeout vs corruption differentiation (no false CORRUPTED on timeout)
- Streaming tar listing to avoid OOM on large archives
For 119GB archives: ~45 min timeout instead of 5 min false-positive
- verifyArchiveCmd now uses restore.Safety and restore.Diagnoser
- Same validation logic in backup manager verify and restore safety checks
- No more discrepancy between verify showing valid and restore failing
- Service templates now use WorkingDirectory for config loading
- Config is read from .dbbackup.conf in /var/lib/dbbackup
- Updated SYSTEMD.md documentation to match actual CLI
- Removed non-existent --config flag from ExecStart
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
- Panic recovery added to parallel backup/restore goroutines
- Variable shadowing fix in restore/engine.go
These bugs caused pg_dump backups to fail through TUI for months.
This is a critical bugfix release addressing multiple hardcoded temporary directory paths
that prevented proper use of the WorkDir configuration option.
PROBLEM:
Users configuring WorkDir (e.g., /u01/dba/tmp) for systems with small root filesystems
still experienced failures because critical operations hardcoded /tmp instead of respecting
the configured WorkDir. This made the WorkDir option essentially non-functional.
FIXED LOCATIONS:
1. internal/restore/engine.go:632 - CRITICAL: Used BackupDir instead of WorkDir for extraction
2. cmd/restore.go:354,834 - CLI restore/diagnose commands ignored WorkDir
3. cmd/migrate.go:208,347 - Migration commands hardcoded /tmp
4. internal/migrate/engine.go:120 - Migration engine ignored WorkDir
5. internal/config/config.go:224 - SwapFilePath hardcoded /tmp
6. internal/config/config.go:519 - Backup directory fallback hardcoded /tmp
7. internal/tui/restore_exec.go:161 - Debug logs hardcoded /tmp
8. internal/tui/settings.go:805 - Directory browser default hardcoded /tmp
9. internal/tui/restore_preview.go:474 - Display message hardcoded /tmp
NEW FEATURES:
- Added Config.GetEffectiveWorkDir() helper method
- WorkDir now respects WORK_DIR environment variable
- All temp operations now consistently use configured WorkDir with /tmp fallback
IMPACT:
- Restores on systems with small root disks now work properly with WorkDir configured
- Admins can control disk space usage for all temporary operations
- Debug logs, extraction dirs, swap files all respect WorkDir setting
Version: 3.42.1 (Critical Fix Release)
- Add install/uninstall and metrics commands to command table
- Add Systemd Integration section with install examples
- Add Prometheus Metrics section with textfile and HTTP exporter docs
- Update Features list with systemd and metrics highlights
- Rebuild all platform binaries
