Changelogs

New

  • topology

    • Added support for generic Global Servers requests with server attributes and service fields and attributes dictionaries, while retaining scope/selection and legacy direct service keys including service_area.

    • Added the device.management.wireless testbed schema for C9800 WMI uplink, addressing, routes, AP profile, RMI, and redundancy-port data.

    • Added compatibility handling that normalizes wireless route next-hop keys to next_hop.

    • Added validation that rejects boolean VLAN IDs and empty wireless route next-hop values.

    • Added unit coverage for wireless management, HA data, route aliases, and cross-field validation.

  • kleenex

    • Added a serializable testbed configuration collector for Clean stages.

    • Transport generated testbed fragments from Clean workers to the parent engine while retaining support for legacy worker result formats.

    • Aggregate successful worker output deterministically and discard it when Clean fails or times out.

    • Overlay generated devices and topology on the effective post-bringup testbed, warn when generated values replace existing values, and validate the result with the topology loader before updating the runtime testbed.

    • Write testbed.clean.generated.yaml and testbed.clean.merged.yaml artifacts for Easypy and standalone Kleenex, with task-specific filenames for task-scope Clean.

  • easypy

    • Made the runtime deadline guard configurable through the easypy.runtime_deadline.guard_seconds pyATS configuration value, with a default of 1800 seconds.

    • Limited the guard to the remaining reservation runtime.

Fix

  • easypy
    • Improved manifest job interrupt handling

      • Ctrl-C is forwarded to all processes in the job so normal cleanup and reporting can complete.

      • A repeated Ctrl-C or a cleanup timeout forcibly terminates any remaining job processes.

      • Fixed interactive job cleanup when the signal relay exits unexpectedly.

    • Modified manifest execution

      • Forward SIGTERM to the job process group when a manifest run is terminated.

      • Terminate the job process group if SIGTERM shutdown does not finish within the shutdown timeout.

    • Modified Task

      • Record pre-registration task timeouts as ERRORED in Reporter.

  • kleenex

    • Apply images supplied by CLI device, group, platform, model, and OS selectors before YAML callable markup processing so replaced image lookup callables are not evaluated.

    • Preserve the clean_devices execution plan when a generated clean.extra.yaml file is merged as JIT clean content.

  • utils

    • Preserve exceptions raised by YAML callables instead of treating them as argument parsing failures and invoking the callable again with different arguments, while retaining legacy raw-string argument handling.

  • pyats

    • Normalized C9800-CL as model: c9800 with submodel: c9800_cl.

  • connections
    • Modified ConnectionManager.instantiate

      • Recreates a disconnected cached connection or connection pool when explicitly supplied constructor inputs differ, including via, positional and keyword arguments, pool size, and pool timeout.

      • Preserves existing connection reuse when arguments are unchanged or omitted.

  • reporter
    • Modified ReportServer

      • Create and close missing task records during forced termination.
