📝 Walkthrough

Walkthrough

The pull request introduces modifications to the backup and restore functionality in the Home Assistant Supervisor. The changes focus on enhancing the control and flexibility of the Home Assistant container management during restore operations. Key modifications include adding a new parameter to control container removal, updating job stage handling, and introducing a mechanism to pass restore job IDs to the Home Assistant container. The changes span multiple files in the supervisor and test directories, affecting core system components like backup management, job handling, and Docker container interactions.

    • I pushed a fix in commit <commit_id>, please review it.
    • Generate unit testing code for this file.
    • Open a follow-up GitHub issue for this discussion.
  • Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
    • @coderabbitai generate unit testing code for this file.
    • @coderabbitai modularize this function.
  • PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
    • @coderabbitai gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.
    • @coderabbitai read src/utils.ts and generate unit testing code.

864-916: LGTM! Well-structured test implementation.

The test effectively verifies the addition of the SUPERVISOR_RESTORE_JOB_ID environment variable during Home Assistant restore operations. Good use of parametrization to cover both partial and full backup scenarios.

Consider adding the following test cases to improve coverage:

  1. Negative test case: Verify the environment variable is not added when Home Assistant is not being restored
  2. Validation test case: Ensure the job UUID format in the environment variable matches the expected pattern

Example negative test case:

@pytest.mark.parametrize(
    ("backup_type", "postbody"),
    [("partial", {"folders": ["share"]}), ("full", {"homeassistant": False})]
)
async def test_restore_without_homeassistant_no_env(
    api_client: TestClient,
    coresys: CoreSys,
    docker: DockerAPI,
    backup_type: str,
    postbody: dict[str, Any],
):
    """Test restoring without home assistant does not add env to container."""
    # Test implementation...
    assert "SUPERVISOR_RESTORE_JOB_ID" not in docker.containers.create.call_args.kwargs["environment"]

18-22: LGTM!

The new imports are correctly placed and necessary for the new test functionality.

supervisor/core.py (2)

336-336: LGTM! Well-designed parameter addition.

The new keyword-only parameter with a descriptive name and safe default value maintains backward compatibility while enabling the new functionality.


347-349: Verify error handling in Home Assistant core stop method.

The implementation correctly forwards the container removal parameter. Since errors are suppressed here, ensure the core.stop() method properly handles container removal failures.

✅ Verification successful

Error handling for container removal is properly implemented

The stop() method implementations across the codebase show appropriate error handling:

  • Base implementation suppresses DockerNotFound errors
  • Container manager handles NotFound exceptions
  • Errors are handled at both caller and implementation levels
🏁 Scripts executed

The following scripts were executed for the analysis:

Script:

#!/bin/bash
# Description: Check error handling in Home Assistant core stop method
# Look for error handling around container removal in the Home Assistant core implementation

# Search for the core.stop() method implementation
ast-grep --pattern 'async def stop($$$) { $$$ }' | grep -A 10 'async def stop'

# Look for error handling around container removal
rg -A 5 'remove_container.*=.*True'

864-916: Well-structured test with comprehensive coverage!

The test effectively verifies that the Home Assistant container receives the correct restore job ID during both partial and full restores. The implementation includes proper mocking, event handling, and assertions.

Consider renaming the test to be more specific about what it's testing, e.g., test_restore_adds_job_id_to_ha_container_env.
