Pull Request Overview

This PR addresses the "Candidate Not Iterable Error" by adding comprehensive safety checks to ensure that candidate objects are iterable before processing. The changes include adding a type guard (isIToolRelease) to validate manifest entries, introducing a safeguard to check for empty release file arrays, and updating tests and workflow configurations to align with these modifications.

  • Added a type guard function to confirm manifest entries adhere to IToolRelease.
  • Introduced an explicit check for empty release.files in installCpythonFromRelease.
  • Updated unit tests and workflow configuration to support validation and error scenarios.

src/install-python.ts:124

  • Ensure that there are corresponding tests covering the scenario where release.files is empty to confirm this safety check behaves as expected.
if (!release.files || release.files.length === 0) {

src/install-python.ts:35

  • Consider adding tests to cover edge cases for the isIToolRelease function, especially when manifest objects contain incomplete or unexpected data.
function isIToolRelease(obj: any): obj is IToolRelease {

tests/install-python.test.ts:30

  • Add tests verifying that an invalid manifest (e.g., missing required properties) correctly triggers the error thrown in getManifest.
