April 2026 (vllm-ascend): Delivered a robust improvement to nightly test artifact uploads by introducing OBS-based artifact upload as an additional mechanism alongside the existing GitHub Actions uploads. Implemented across three reusable nightly workflows to enhance reliability on self-hosted runners with limited connectivity to GitHub artifact storage. Maintained both upload paths with continue-on-error to ensure CI resilience and avoid blocking workflows. Restored the artifact merge step with continue-on-error to preserve stable nightly results. Added OBS credentials (OBS_ACCESS_KEY, OBS_SECRET_KEY) to repository secrets and wired them into the workflows for secure access to Huawei Cloud OBS. What changed at a glance: - Dual-path artifact uploads: actions/upload-artifact and OBS uploads - Self-hosted runner resilience: continue-on-error on uploads and merge steps - Secrets and configuration: OBS keys added to repo secrets and propagated to 3 nightly workflows - No user-facing changes: CI infrastructure only; artifacts now stored in GitHub Actions and Huawei Cloud OBS Testing and validation: - Controllers configured with required OBS secrets; nightly workflows triggered to verify parallel uploads without blocking on failures.
