Summary

  • Extract common action-plugin setup into BaseResourceActionPlugin._prepare_action()
  • Add _build_resource() as an extension hook for non-CRUD action plugins
  • Preserve the existing CRUD state machine while adding focused unit coverage

Validation

  • Syntax checks passed.
  • git diff --check passed.
  • Local pytest execution was unavailable because the workspace environment does not have pytest/Ansible installed.

This is intended as a prerequisite refactor for migrating ad_hoc_command without duplicating the base setup pipeline.

Summary by CodeRabbit

  • New Features

    • Action plugins now share consistent preparation and resource-construction support across workflows.
  • Bug Fixes

    • Preparation failures now preserve and return the original error message instead of triggering an additional internal error.

📝 Walkthrough

Walkthrough

_prepare_action() now has expanded documentation. Unit tests cover its preparation workflow and verify that preparation errors preserve their original messages.

Changes

Action preparation contract

Layer / File(s) Summary
Preparation contract and validation
plugins/action/base_action.py, tests/unit/plugins/action/test_base_action.py, changelogs/fragments/base_action_preparation.yml
The _prepare_action() documentation describes its arguments and dictionary return value. Tests cover documentation loading, argument validation, manager acquisition, data separation, facts, deprecations, resource construction, and missing documentation.
Preparation error preservation
tests/unit/plugins/action/test_base_action.py
A regression test verifies that failed preparation results retain the original error message.

Priority: ⬇️ Low

Estimated code review effort: 2 (Simple) | ~10 minutes

Change: Refactor

Merge Risk: 🔵 Low · up to 140b3

The implementation is otherwise ready, but the hook's runtime dispatch should be covered before relying on this refactor for non-CRUD action plugins.

1108-1108: 🎯 Functional Correctness | 🟠 Major | 🏗️ Heavy lift

Use _build_resource() for the enforced update path.

When state is enforced and find returns a resource, line 1231 constructs self.MODEL_CLASS directly. This bypasses a subclass _build_resource() override. A subclass that removes control-only fields or maps input values can fail during an enforced update, although its create path works.

Replace the direct construction in the enforced branch with _build_resource().

Contributor Author

Addressed the in-scope review feedback in 09add7c: initialized the fallback Ansible result before action preparation and added regression coverage so preparation failures preserve their original message instead of being masked by an unbound result error. The other comments concern files not changed by this focused base-action refactor PR and are intentionally left for the ad hoc command/client follow-up.

69-72: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick win

Test an actual _build_resource() override.

test_build_resource_is_overridable calls the inherited implementation on ExampleAction; it does not define an override or exercise BaseResourceActionPlugin.run(). The test would pass if the run path stopped dispatching this hook. Add a subclass override and assert that the run path invokes it.
