Oct 1, 2025October 2025 — psleng/vyos-1x: Reinstated core stability and baseline boot behavior with targeted feature delivery and bug fixes. This month focused on re-establishing correct BGP VRF/system-AS behavior, ensuring reliable first-boot initialization, and restoring logging and debugging capabilities to support faster troubleshooting and safer deployments. Key outcomes include: improved routing stability with per-VRF system-AS restoration, a safer and more predictable first-boot experience, reduced runtime instability from airbag handling, regression-free image installation due to removal of unnecessary CLI kernel options calls, and enhanced diagnostic visibility via restored logs.

May 1, 2025May 2025 highlights: The VyOS 1x project delivered a focused set of Vyconf integration, testing, interoperability, and reliability improvements that enhance configuration safety, testing coverage, and deployment agility. Key features delivered include Vyconf-backed Config initialization from VyconfSession with session population and mode separation, plus test-harness compatibility. A new Vyconf smoketests utility enables running Vyconf-backed tests across Vyconf-enabled configurations. To improve interoperability with older deployments, a startup option to load legacy config on start was added. On the robustness front, we introduced existence checks for critical paths/tables, migrated to PCRE2 for regex processing, clarified error phases in configd (verify vs apply), ensured a default version string on init from internal cache, and added an automatic rollback utility for apply-stage errors. Deployment and API agility were enhanced with HTTP API support for passing config strings in load and merge requests, and new commit-confirm endpoints, complemented by config-management defaults improvements. Technical competencies demonstrated include Vyconf integration, PCRE2 migration, test harness alignment, Python-based CLI tooling, environment variable ergonomics (vyconf_bin_dir), and security-conscious privilege checks. Business value: reduced risk during config changes, faster validation and rollout of Vyconf capabilities, legacy interoperability, and improved developer experience and security.

Jan 1, 2025January 2025 performance summary for psleng/vyos-1x: Delivered foundational enhancements to improve runtime reliability, developer productivity, and diagnostics. Implemented enhancements to reference tree cache management, enabling efficient cache merging and JSON rendering, with a cleaner addon cache directory and updated dependencies. Added end-user and developer-facing visibility to configuration changes via Show Commit Data data binding and CLI, facilitating quick comparison of changes across two configuration trees. Introduced XML Include Globbing to simplify XML composition through wildcard patterns. Refactored the VyOS-1x Config Tree Library for consistency with formatting standards, type hints, and improved error handling, reducing maintenance burden. Strengthened configd reliability by introducing an Enum for response codes and correcting misleading debug messages, aligning behavior with shim error codes. These changes collectively improve stability, troubleshooting speed, and development velocity, setting the stage for full vyconfd support and broader automation readiness.

Nov 1, 2024In November 2024, the team delivered three targeted updates for psleng/vyos-1x focused on reliability, determinism, and maintainability. The inter-component communication protocol between configd and vyshim was overhauled to use a single multipart message, reducing race conditions and improving throughput. Build reproducibility was achieved by pinning specific versions of required packages vyos1x-config and vyconf in build.sh, ensuring consistent builds across environments. The UI/CLI was simplified by removing the 'show configuration files' node and its script, reclaiming resources for future features. These changes collectively reduce operational risk, accelerate deployments, and improve developer experience.
