Changelogs

New

• kleenex

  • Added process-safe coordination for parallel Clean workers, including readiness, completion, failure, and timeout handling.

  • Generated Clean coordination metadata is honored without requiring a clean_devices entry in the Clean configuration.

  • Clean now reports worker failures instead of silently omitting workers

Fix

• kleenex

  • Keep Clean stages declared with an empty body (e.g. connect:) as empty dicts instead of removing them, fixing “Stage ‘<name>’ has no configuration in clean.yaml” errors.

  • Remove None-valued entries from merged Clean configuration before it is displayed, saved, and applied to the testbed.

  • Added standalone xUnit reporting

    • Support –xunit and –xunit-include-logs with pyats clean, including an alternative output directory.

    • Keep xUnit generation disabled unless explicitly requested.

    • Finalize reporting when Clean engine initialization fails before any device section starts.

  • Easypy now reserves five minutes before an active runtime deadline and passes the remaining Clean budget through a private engine integration path.

  • Bounded that shared invocation timeout across parallel workers, sequential device groups, debug mode, and full-Clean recovery retries.

  • Added bounded worker and descendant termination with SIGKILL fallback when a runtime or per-device timeout expires.

  • Made worker-result publication atomic so deadline cleanup cannot block on a partially written result. The public timeout= API retains its per-worker behavior, including the existing timeout=0 fallback; zero on the private invocation path prevents a worker from starting.

  • Fixed coordinated Clean execution in debug mode and when a worker exits before coordination completes.

• easypy

  • Modified XunitPlugin

    • Generate requested xUnit reports after job reporter finalization when a pre-job plugin fails.

    • Add a standard JUnit testcase for unsuccessful top-level job plugins and include the OneDevX reference when available.

    • Exclude non-rollup sections from XML counts and time while retaining independently reportable children.

    • Retain testcases when optional logs cannot be read.

  • Updated xUnit reports to omit intermediate retry attempts and include the final result. Runs without retries are unchanged.

• kleenex / easypy

  • Improved Clean device-selection logging

    • Log --clean-devices selections separately from configuration defaults and effective device alias/name mappings, without changing Clean targets.

• cisco

  • Modified BringupSubcommand

    • pyats testbed bringup --clean-file no longer fails with an empty StopIteration error when the clean file only has a bringup section and no cleaners.
