v6.50.27 — Unit Test Coverage Expansion

Unit Test Coverage Expansion

7 new test files (1,862 lines) covering pure/deterministic functions across 5 packages:

Package	Before	After
notify	22%	44.2%
dedup	5.4%	23.6%
pitr	13.5%	21.3%
performance	29.3%	36.6%
wal	9.5%	11.8%

All tests pass on Go 1.24.0 and PostgreSQL 18.2.

v6.50.24: Fix pipe race condition in globals backup, Enterprise section

v6.50.24: Fix pipe race condition in globals backup, Enterprise section

Fixed

• Pipe race condition in globals backup — cmd.Wait() closes the stdout pipe; if io.ReadAll() hasn't finished reading, it crashes with read |0: file already closed. Fixed by draining the pipe completely BEFORE calling Wait(). Affected both backupGlobals (PostgreSQL/pg_dumpall) and backupMySQLGlobals (mysqldump). Triggered on mysql01 where mysqldump exits quickly due to LOCK TABLES warning on ejabberd database.

Added

• Enterprise & Consulting section in README — UUXO background, service offerings (backup strategy, DR planning, deployment, support contracts, training), contact info

Changed

• License section clarified — Apache 2.0, explicitly free for everyone including enterprises

v6.50.23: SFTP cloud storage backend

v6.50.23: SFTP cloud storage backend

Added

• internal/cloud/sftp.go (NEW) — SFTPBackend implementing cloud.Backend interface for remote backup-to-server via SSH/SFTP
  • Upload() — Streaming upload with auto-mkdir on remote, retry, bandwidth throttling, progress tracking
  • Download() — Streaming download with context cancellation, bandwidth throttling
  • List() — sftp.ReadDir() with prefix filtering, skips directories
  • Delete() — sftp.Remove() with path prefix
  • Exists() / GetSize() — sftp.Stat() with os.IsNotExist() handling
  • Lazy SSH+SFTP connection (first operation triggers connect)
  • SSH auth chain: explicit key → default keys (~/.ssh/id_ed25519, id_rsa, id_ecdsa) → password
  • Host key verification via known_hosts or --sftp-insecure to skip
• internal/cloud/sftp_test.go (NEW) — Unit tests: validation, buildFilePath, parseSFTPEndpoint, buildSSHAuthMethods, buildHostKeyCallback
• CLI flags: --sftp-key (DBBACKUP_SFTP_KEY), --sftp-key-passphrase, --sftp-password, --sftp-known-hosts, --sftp-insecure on all cloud commands
• URI schema: sftp://user@host:port/path (e.g., sftp://backup@nas.local/mnt/backups)
• Config persistence: sftp_key, sftp_key_passphrase, sftp_password, sftp_known_hosts, sftp_insecure in [cloud] section of .dbbackup.conf

Changed

• internal/cloud/interface.go — Added SFTPKeyPath, SFTPKeyPassphrase, SFTPPassword, SFTPKnownHostsPath, SFTPInsecure to Config; "sftp" case in NewBackend() factory; Validate() skips bucket requirement for sftp provider
• internal/cloud/uri.go — sftp:// in validProviders, IsCloudURI(), SFTP-specific parsing (user@host:port from URI userinfo+host, path as prefix)
• internal/config/config.go — Added CloudSFTP* fields
• internal/config/persist.go — LocalConfig extended, load/save/apply for SFTP fields
• cmd/cloud.go — SFTP flags, getCloudBackend() wiring, bucket validation skip for sftp
• internal/backup/engine.go — uploadToCloud() now passes HMAC and SFTP config fields to cloud.Config (was missing for both)

Notes

• 7th cloud provider — purely additive, no breaking changes to existing S3/MinIO/B2/Azure/GCS/HMAC backends
• Only requires SSH credentials — no S3/NFS/SMB infrastructure needed
• Dependency added: github.com/pkg/sftp v1.13.10 (uses existing golang.org/x/crypto/ssh)

v6.50.17: Refactor engine.go — split into 7 focused modules

Split internal/restore/engine.go (3,855 lines) into 7 focused files. Purely organizational refactoring — no functional changes, no renamed functions, no signature changes. Test coverage unchanged at 20.1%.

New files:

• engine_util.go — Utility functions
• engine_exec.go — Command execution, decompression pipeline
• engine_tuning.go — PostgreSQL server tuning
• engine_mysql.go — MySQL restore methods
• engine_postgresql.go — PostgreSQL restore methods
• engine_cluster.go — Cluster restore, globals, metadata
