Oct 1, 20252025-10 Monthly Summary for axoflow/axosyslog: Delivered Valgrind CI integration and reporting enhancements to boost memory-leak detection reliability, accelerate triage, and provide actionable failure data. Implemented a dedicated Makefile target for Valgrind tests, a nightly GitHub Actions workflow, and a Python script to parse Valgrind output, with workflow naming adjustments to avoid conflicts and a focused test subset to fit runtime constraints. These changes collectively shorten feedback loops, reduce production risk, and improve long-term stability of memory-related defects.

May 1, 2025In May 2025, delivered observability enhancements for the axosyslog component that enable reliable monitoring and analysis of Loggen performance. Implemented get_loggen_stats() in the Loggen class to retrieve runtime statistics and introduced a LoggenStats class to parse and hold these metrics. Statistics are parsed from the last line of the Loggen stderr file, ensuring robust data extraction for dashboards and alerting. This work provides a foundation for data-driven performance optimization and proactive issue detection.

Apr 1, 2025April 2025 — axoflow/axosyslog: Config and Test Version Management Enhancements focused on centralizing version handling, improving test reliability, and enabling reproducible deployments. Introduced a dedicated config_version fixture and integrated it into config fixtures, refactored version retrieval into a shared helper, and updated SyslogNgConfig to store config_version instead of a generic version. Note: major feature work with alignments to release processes and future environment-scoped versioning.

Jan 1, 2025January 2025: Implemented automated Docker image tagging and versioning for axosyslog, deriving tags from Git tags and prior image tags with automatic version increments for new releases and rebuilds, including warnings when a lower Git tag is used to maintain correct versioning. Updated the axosyslog-docker workflow's merge-and-push job to integrate the tagging/versioning logic, enabling streamlined, auditable releases. No major bugs fixed this month.
