Changelogs

New

• kleenex

  • Retry a device’s complete Clean workflow when its cleaner reports that device recovery succeeded. The retry budget defaults to one and can be configured with --clean-retries (or -clean_retries for the legacy command) using a non-negative integer. Set it to zero to disable retries; successful recovery then leaves the unretried failure as the final Clean result.

  • Preserve the superseded attempt in results.json without including it in result rollup, and report a successful retry as PASSX.

  • Add structured Clean retry attempt, trigger, and status metadata for future UI consumers.

• reporter

  • Exclude sections stopped with result_rollup=False from summaries and mark them as ignored in serialized reports.

Fix

• topology

  • Modified topology lookup and link collection

    • Detects duplicate link names in a single pass without maintaining an incremental link registry

    • Uses keyed lookups before alias scans while preserving device object membership after a device name change

• utils

  • Modified entry-point discovery

    • Caches entry-point lookups for the lifetime of the process

  • Modified Schemaengine

    • Fixed required-key rendering so Required("key", description=...) reports the wrapped key name in missing-key errors instead of the schema wrapper text.

  • Preserve the legacy requirement project_name alias without mutating packaging.Requirement objects, adding compatibility with packaging 26.3 and later.

• ci

  • Modified pull request package builds

    • Builds both regular and Cythonized public alpha packages

• easypy

  • Modified TaskManager

    • Loads reservation end time deadlines from testbed custom data in core task handling.

    • Logs runtime deadline details before task start.

    • Reports runtime deadline task termination as an errored task.

• reporter

  • Modified stop_testsuite

    • Finalize any section that was started but never stopped (e.g. a forked worker was force-terminated before reporting) so it shows a runtime and an errored result in the reports/UI instead of appearing blank with only a start time.

    • Roll the synthetic errored result up through the parent section, task, and suite summaries so reports no longer advertise a passing run while a descendant section is errored.

    • Publish a stop_section update for each finalized section so subscribers that already received the start_section get the matching runtime/result without needing a full reload.

• devat

  • Added lab-compliance reporting for PDUs without a management IP address.

• cisco

  • Modified version update

    • Include ats.cisco and ats.devat when looking up and reinstalling the latest internal package versions.

  • Modified the default SMTP configuration

    • Enabled STARTTLS for outbound.cisco.com because the Cisco SMTP relay now requires TLS connections.

• kleenex

  • Modified clean template merging

    • Preserves user-defined clean stages omitted from template order.

    • Keeps numbered and unnumbered instances of the same stage adjacent.

    • Excludes non-stage clean metadata from the execution order.
