2 Commits • 2 Features
Feb 1, 2026February 2026 (openSUSE/open-build-service): Delivered two reliability-focused enhancements that strengthen the build and upload pipeline. Implemented chunked transfer encoding for uploads to bs_rekor, and added automatic abortion of stuck build jobs after 30 minutes of vCPU inactivity. These changes improve upload reliability, prevent indefinite hangs, and shorten feedback loops, delivering measurable business value in reliability and efficiency.

Jan 1, 2026In 2026-01, the team delivered a stability-focused bug fix in the bs_publish backend of openSUSE/open-build-service. A defensive check was added to ensure embargo_date exists before applying a regex, preventing undefined runtime errors during embargo processing. This addresses a critical reliability risk in embargo-based publishing workflows and reduces potential production issues. Commit 9650b07f68bf7ab9fdfa6247ab25ea0bc42a6be0 implements the change with the message "[backend] silence undefined warning in bs_publish".

Dec 1, 2025December 2025 monthly summary for openSUSE/open-build-service: Implemented a backend SBOM discovery enhancement for ISO installable images, improving reliability and SBOM compliance in the publish workflow. The change ensures SBOMs are correctly located in the ISO subdirectory even when the ISO filename includes the .install suffix, reducing publishing errors and manual intervention.

May 1, 2025For 2025-05, the team delivered a focused backend reliability fix for openSUSE/open-build-service, addressing WSL Build Artifacts Publishing. Major bug fixed: backend now correctly handles WSL files by recognizing the .wsl extension and implementing explicit path handling to ensure WSL build artifacts are processed and published. This reduces failed artifact publishing in WSL CI runs, improves consistency across environments, and strengthens Windows Subsystem for Linux support. The change improves artifact visibility in publish pipelines and reduces manual re-publishing efforts. Technologies/skills demonstrated include backend logic updates, path handling, file extension filtering, and CI/CD artifact publishing workflows; commits show targeted backend work.

Jan 1, 2025Month 2025-01 — Open Build Service: delivered a critical bug fix improving SLSA provenance handling when debugsplit is enabled. The change ensures provenance files are correctly moved with RPMs and that the filtering logic properly includes/excludes provenance data, maintaining build reproducibility and security compliance. This work reduces the risk of mismatched provenance in RPM-based artifacts and strengthens the overall security posture of the build system. Tech focus included build system internals, RPM packaging, and SLSA provenance.
