Summary

  • Clear open Dependabot alerts on uv.lock for filelock, Pillow, and dnspython by pinning patched versions (filelock>=4.2.1, pillow>=13.0.0, dnspython>=2.9.0) via tool.uv.constraint-dependencies and refreshing the lockfile.
  • Raise requires-python to >=3.11 because fixed releases of those packages no longer publish wheels for Python 3.10; the universal lock previously kept vulnerable 3.10 resolution forks (e.g. filelock 4.1.0, pillow 12.3.0, dnspython 2.8.0), which Dependabot continued to flag.
  • Align tooling with the new floor: drop the 3.10 Trove classifier, bump mkdocs-ansible to >=26.4.0, and update tox lower bound, CI lint default Python, mypy/ruff targets, and Sonar Python versions.

Test plan

  • uv lock --check
  • tox -e lint
  • tox -e py (or CI matrix)
  • Confirm GitHub Dependabot alert count drops after merge (may lag briefly)

Breaking change

Python 3.10 is no longer supported for installing Molecule from this branch. Users on 3.10 must upgrade to 3.11+.

Summary by CodeRabbit

  • Compatibility

    • The minimum supported Python version is now 3.11; Python 3.10 is no longer supported. Development and quality-checking tools now target Python 3.11 and newer.
  • Dependency Updates

    • Minimum versions for several dependencies have been raised, including filelock, dnspython, and pillow. Documentation tooling requirements have also been updated.

Patched filelock, Pillow, and dnspython require Python 3.11+, so raise
requires-python and constrain transitive deps before re-locking.

Walkthrough

The project now requires Python 3.11 or newer. CI, linting, type-checking, and Sonar settings align with that minimum. Several dependency minimums increase. Source typing and lint directives also change.

Changes: Python baseline and tooling

Layer / File(s) Summary
Set Python 3.11 as the target
.github/workflows/tox.yml, pyproject.toml, sonar-project.properties
The declared minimum Python version changes to 3.11. Linting, type-checking, tox, and Sonar configuration no longer target Python 3.10.
Update dependency minimums
pyproject.toml
The minimum versions for filelock and mkdocs-ansible increase. UV constraints add minimum versions for dnspython, filelock, and pillow.
Adjust typing and lint directives
src/molecule/ansi_output.py, src/molecule/api.py, src/molecule/compatibility.py
Self is imported from typing. The PERF203 suppression is removed, and UP042 is added to the suppression list.

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

Change: Bug fix

Suggested reviewers: cidrblock, ssbarnea

Merge Risk: Minimal · up to c4ce9

The change is mergeable; replacing the vendored StrEnum is an optional cleanup.

Full details: Title check

Explanation

The title says the PR resolves Dependabot alerts in uv.lock. The changeset does add minimum version constraints for filelock, Pillow, and dnspython and refreshes the lock state. It also raises the Python floor to 3.11 and updates tooling. The title covers the security motivation but omits the main breaking change (dropping Python 3.10). That makes it a partial match, which still passes under the criteria.

Minor · Functional Correctness · Quick win

Use Python 3.11 in both documented CI recipes.

The package requires Python >=3.11, but the GitHub Actions matrix still runs its installation job on Python 3.10. The Azure example also selects Python 3.10 before installing molecule[lint]. Following either recipe can fail because the current package cannot be installed on Python 3.10.

Suggested fix
-        python-version: ["3.10", "3.11"]
+        python-version: ["3.11"]
-          versionSpec: "3.10"
+          versionSpec: "3.11"

filelock 4.2+ requires Python 3.11; set min_python for CI and satisfy
ruff after dependency updates on the security lock refresh.

Use the standard-library enum.StrEnum.

The package now requires Python 3.11, so the vendored Python 3.10 implementation is unnecessary. Import StrEnum from enum and remove the copied class. This also removes the need to suppress UP042 while preserving the module-level name.

In the compatibility module, replace the vendored StrEnum implementation with
StrEnum imported from the standard-library enum module, preserving the
module-level StrEnum name. Remove the now-unneeded UP042 suppression while
leaving the other lint suppressions unchanged.
