Sep 1, 2025September 2025: Build Environment Stabilization and OS Version Maintenance for topolvm/topolvm. Stabilized CI/test environments by reverting OS version from Ubuntu 24.04 to 22.04 and updating the Docker base image to Debian bookworm to ensure runtime parity. Established a maintenance process for OS version updates, prioritizing the oldest supported Ubuntu LTS in coordination with Kubernetes updates to reduce drift and upgrade risk. All changes are traceable to dedicated commits for reproducibility across CI and release pipelines.

Jun 1, 2025June 2025 monthly summary for topolvm/topolvm: Delivered a targeted cleanup to standardize volume size handling by removing deprecated size_gb fields from protobuf definitions and related logic, and standardizing on size_bytes for all size-related operations. This reduces legacy cruft, improves consistency across components, and lowers the risk of size representation inconsistencies. The change is a focused, low-risk refactor with a clear path for future API cleanups.

Jan 1, 2025Month: 2025-01 — Focused on strengthening test coverage and maintainability for VG service in topolvm/topolvm. Refactored VG Service tests to improve readability and reliability: GetFreeBytes now uses subtests for 'thick lv' and 'thin lv'; GetLVList tests converted to table-driven tests to cover multiple volumes across thick and thin device classes. Commits: 653eb072af738dfd539c46c6ea97a740bf6d0008, 8316c23ab1e379989e8e32c4f9fb6a12b90e978b. No major bug fixes were documented this month; primary focus was test architecture and quality. Impact: improved test reliability, faster validation of VG service changes, easier onboarding for new contributors. Technologies/skills: Go testing patterns (subtests, table-driven tests), test readability improvements, disciplined commit hygiene.
