April 2025

1 Commits

Apr 1, 2025

April 2025 monthly summary for grafana/shared-workflows focused on reliability and maintainability of the shared-workflows module. Key achievement this month was stabilizing the test suite by ensuring the main() function does not execute during import, preventing unintended side effects during import and flaky test failures. The final fix was implemented in the commit that refactors the lint-pr-title behavior to guard main execution with an entry-point check. This work reduces CI churn and makes tests deterministic, enabling smoother future iterations. No new user-facing features released this month; core emphasis was on code quality, test reliability, and alignment with Python linting practices.
