Changelog

Release history and changelog for Godwit Sync.

0.2.3

Verify observability and drain timeout

Released on 2026-04-02

New features

  • Verify metrics in plan verify server. The /status endpoint now exposes verify counts alongside sync progress, giving dashboards and monitoring tools a single source of truth for both operations.
  • Verify resume pre-seeding. When resuming a verify operation, previously completed counts are loaded from the task repository so progress starts from where it left off.
  • --drain-timeout flag. Controls how long the process waits for in-flight operations to complete before shutting down. Also available as a config field.
  • Full observability lifecycle for verify. The verify command now emits the same Prometheus metrics, status-server updates, and console events as the sync command.
  • Live stats and object gauges during sync. Real-time object-level gauges are emitted during sync operations, improving visibility in Prometheus and Grafana dashboards.
  • Pre-initialized Prometheus metric labels. Dashboard panels no longer show "No data" on startup; all metric labels are registered with zero values at initialization.

Fixes

  • Tracker Reset semantics. Corrected the counter reset behavior and added pending counts to the progress tracker.
  • License limit reached event. The brief console output now reports when the license object limit is reached, instead of silently stopping.

0.2.2

Verify fix for versioned buckets

Released on 2026-03-30

Fixes

  • Exclude delete markers from verification. The verify command no longer attempts to verify S3 delete markers, which caused false failures when verifying versioned bucket migrations.

0.2.1

Version-aware S3 migration

Released on 2026-03-21

New features

  • Version-aware S3 bucket migration. Godwit Sync can now migrate all object versions from a versioned S3 bucket, not just the latest version. Version IDs are tracked on both source and destination, and partial version history is reported during the operation.
  • Object lock migration. Retention policies and legal holds are preserved when migrating objects between S3-compatible storage systems.
  • --config flag for plan commands. Plan, sync, and verify commands can now read settings from a YAML configuration file instead of requiring all options as CLI flags.
  • --unsupported-key-action=warn mode. Objects with keys that the destination does not support are logged with per-object events instead of failing the entire operation.
  • --case-conflict and --unsupported filters. The plan list-objects command can now filter its output to show only objects with case-conflicting keys or unsupported key characters.
  • Post-upload version tag replication. After uploading each version, a PutVersionTags call confirms that the destination has recorded the correct version ID, catching replication mismatches early.

Changes

  • Match config moved to policy section. The match configuration block has moved from the versioning section to the policy section in the config file.

0.1.4

Config file support and extended plan list

Released on 2026-03-11

New features

  • Config file support for verify. The verify command now accepts configuration from a YAML file, matching the config support already available in plan and sync.
  • Read config from file. All commands that accept --config can now load settings from a file path.

Fixes

  • Brief plan output shows zero counters. Fixed a bug where the non-UI console output displayed zero for all object and byte counters. The TTY message factory was reading flat payload keys instead of the nested objectStats struct.

0.1.2

Retry support and cross-platform build fixes

Released on 2026-03-06

New features

  • --retry and --retry-backoff flags. Failed object transfers are now retried automatically. Configure the maximum number of attempts with --retry and the backoff interval with --retry-backoff.
  • Sync direction in header. The console output header now shows the sync direction (e.g., s3→fs, fs→s3, s3→s3) for easier identification.
  • New Prometheus counters. Additional metrics for monitoring transfer operations.

Fixes

  • CGO enabled for SQLite. Previous builds were compiled with CGO_ENABLED=0, causing runtime crashes because go-sqlite3 requires CGO. All release binaries are now built with CGO enabled.
  • ARM64 Docker builds stabilized. Fixed intermittent failures in ARM64 Docker builds running under QEMU emulation.
  • SQLite atomic alignment warnings suppressed. Eliminated noisy compiler warnings on ARM targets.

0.1.1

Initial release

Released on 2026-02-27

Features

  • S3-to-filesystem, filesystem-to-S3, and S3-to-S3 sync. Transfer objects between any combination of local filesystem and S3-compatible storage (AWS S3, MinIO, and other S3-compatible providers).
  • Plan-based architecture. Every sync operation starts with a plan that inventories source and destination, calculates the diff, and records what needs to be transferred. Plans can be inspected before execution.
  • Resume interrupted transfers. If a sync operation is interrupted, resume from where it left off without re-transferring completed objects.
  • Verify after sync. A dedicated verify command compares source and destination after a sync to confirm all objects were transferred correctly.
  • Interactive terminal UI. A Bubble Tea terminal interface shows real-time progress with object counts, byte counters, and transfer speed.
  • Brief console mode. Run with --ui=false for a non-interactive log-style output suitable for scripts and CI pipelines.
  • Prometheus metrics. Built-in metrics endpoint for monitoring sync operations with Prometheus and Grafana.
  • License validation. Commercial license support via the Godwit license server.
  • Multi-platform binaries. Pre-built binaries for Linux (amd64, arm64, armv6), macOS (amd64, arm64), Windows (amd64), and a Docker image.
