📝 Summary

Summary by CodeRabbit

  • New Features

    • Added REST-based hostname management for setting, replacing, gathering, and deleting the system hostname.
    • Added check-mode command reporting, configuration persistence, save-status reporting, and post-change verification.
    • Added idempotent deletion behavior and clearer errors for hostname retrieval or verification failures.
  • Bug Fixes

    • Corrected the hostname bugfix changelog wording.
  • Documentation

    • Updated hostname workflows, examples, supported operations, parameters, and return values.
    • Removed documentation for unsupported connection parameters and rendered/parsed states.
  • Tests

    • Expanded unit and integration coverage for hostname lifecycle, validation, check mode, and idempotency.

Walkthrough

Changes

The vyos_hostname module now manages the system host-name path through VyOSModule and REST API command tuples. It supports hostname configuration states, check mode, saving, readback, and explicit REST errors. Tests and documentation reflect the new interface.

Hostname REST API rework

Layer / File(s) Summary
Shared REST helper updates
plugins/module_utils/vyos.py
VyOSModule.get_value retrieves scalar values through the REST client. Integer casting preserves lists with more than one element.
Hostname module execution flow
plugins/modules/vyos_hostname.py, docs/vyos.rest.vyos_hostname_module.rst, changelogs/fragments/t8989_hostname_rework.yml
The module uses REST retrieval, command tuples, save status, response data, readback, and command-aware check mode. Documentation and the changelog describe the supported states and return values.
Hostname validation and integration coverage
tests/unit/modules/test_vyos_hostname.py, tests/integration/targets/vyos_hostname/tests/httpapi/*
Tests cover command generation, gathered output, supported arguments, deletion, idempotency, overrides, and hostname round trips.

Priority: ➖ Normal

Merge Risk: 🟡 Moderate · up to 63cf2

A malformed or unexpectedly multi-valued integer REST response can fail configuration normalization. Resolve or explicitly accept this remaining shared-helper risk before merge.

Pull request overview

Reworks the vyos_hostname Ansible module in the vyos.rest collection to better align with the REST API model (treating system host-name as a scalar leaf), simplifying supported states and updating tests/docs accordingly.

Changes:

  • Refactors vyos_hostname to use the shared VyOSModule helper and introduces a dedicated get_value() API for scalar leaf retrieval.
  • Updates/extends unit + integration coverage for gathered/merged/replaced/overridden/deleted behaviors.
  • Refreshes module docs/README entries and adds a changelog fragment for the hostname rework.

154-156: 🩺 Stability & Availability | 🟠 Major | ⚡ Quick win

Preserve multi-value integer lists before casting.

When entry[key] contains multiple values, Line 154 leaves the list in val, but Line 156 still calls int(val). This raises TypeError instead of preserving the list. Skip the scalar cast for lists longer than one element and add a regression test.

Proposed fix
             val = entry[key]
-            if isinstance(val, list) and len(val) <= 1:
+            if isinstance(val, list):
+                if len(val) > 1:
+                    continue
                 val = val[0] if val else None
             entry[key] = int(val) if val is not None else None
