34 Commits • 12 Features
Jun 1, 2026June 2026 focused on strengthening cluster resilience, automation of evacuation-related topology changes, and improved developer experience. Key work delivered includes an evacuated-member rebalancing framework with helper funcs, quorum checks, leader-triggered rebalances, and raft rebalances after evacuation/restoration (plus heartbeat checks and action constants); a new ProjectReplicaModeUpdate operation type to support per-project replica mode changes; and visibility improvements for cluster links via a UsedBy field and related API extensions. Fixes included restoring path support for unclustered standby clusters and preventing duplicate replicators targeting the same cluster link. The period also encompassed documentation and tooling enhancements (Swagger refresh, API anchors, metadata updates, AGENTS.md/COMMITS.md, and new tests) to improve reliability, governance, and developer productivity.

Jan 1, 2026January 2026 (2026-01) delivered meaningful business value across LXD's cluster governance, migration reliability, and storage capabilities. Key changes include cluster-wide evacuation exclusivity with fixed references, conflict-aware insertion via CreateOperation, stabilization and backwards-compatibility for stateless migrations, server-side force-delete support, and expanded volume snapshot capabilities. In addition, error handling and messaging were standardized, test infrastructure was enhanced to reduce flakiness and accelerate validation, and REST API/docs were refreshed to reflect changes. These outcomes reduce upgrade risk, prevent operational contention, and enable faster, safer deployments in production clusters.

Jun 1, 2025June 2025 focused on strengthening context handling, cluster API reliability, and post-migration workflows, while boosting test coverage and maintainability. End-to-end context propagation for remote certificate retrieval was implemented across core components (shared, lxd, lxd-migrate, and lxd/instance initialization), improving traceability and cancellation behavior in distributed operations. Cluster API hardening included evacuateInstances mode validation, cleanup of evacuateMigrateFunc API signature, and documentation of valid ClusterMemberStatePost.Mode values to prevent misconfigurations. Post-migration workflow enhancements introduced postMigrateSendCommon and its wiring into MigrateSend, along with clusterMoveSourceName support in PostMigrateSend, ensuring correctness during cluster moves and reducing post-migration errors. Reliability and maintainability improvements covered unix socket handling (removal of stale sockets, host-bind removal policy, and renaming UnixSocket to GetUnixSocket), plus refreshed Swagger YAML and formatting tooling. Testing and tooling enhancements added is_backend_available, expanded clustering_move tests, a VM memory-percentage test, and tests for bridging NIC snapshots to localhost remote, strengthening release confidence across scenarios.
