Mar 1, 2026March 2026 – Delivered reliability and CI/CD improvements for quay/quay with a focus on parallel test stability and faster release cycles. Implemented a critical deadlock fix in test_has_garbage under pytest-xdist, and enhanced the quay frontend CI/CD to build on every commit while eliminating port collisions by using ephemeral ports. These changes reduce flaky tests, improve deployment tempo, and optimize resources in parallel environments. Key techniques included transaction-aware retry logic, per-repo GC adjustments for test isolation, and ephemeral port handling in tests.

Feb 1, 2026February 2026 (2026-02) highlights focused feature delivery and security-oriented test coverage for quay/quay. Key enhancement delivered action logging improvements to support ESS Events of Interest (EOI) with detailed request context and redaction of sensitive query parameters, plus addition of new logging fields for richer observability. Tests updated to use non-credential tokens for basic authentication, increasing security and coverage. No major defects fixed this month; primary impact comes from improved observability, compliance alignment, and security posture.

May 1, 2025May 2025: Focused dashboard maintenance for quay/quay, delivering a Grafana SLO dashboard cleanup to reduce noise and keep metrics relevant. Specifically removed unused panels from the Grafana SLO dashboard, including panels related to 'Push Operations ALB (SLO 99.5%)' and 'Pull Operations Derived from ALB (SLO 99.9%)', streamlining the monitoring surface and improving signal quality for SLO reporting. Implementation tied to commit 5839b5f84fb2829e1a5cd065cc47ae1e6a7f105f (dashboard: removed unused panels from slo dashboard (PROJQUAY-8881) (#3847)).
