Description

The current CI pipeline executes all tests against a single Python version (3.13). To ensure broader compatibility and prevent regressions on other supported Python versions, we should implement a matrix build strategy in the Forgejo Actions workflow.

This would involve configuring the test jobs (unit_tests, integration_tests, etc.) to run on a matrix of Python versions, for example: [3.11, 3.12, 3.13].

Subtasks

  • Modify .forgejo/workflows/ci.yml to include a strategy.matrix.python-version for test-related jobs.
  • Update the steps within the jobs to use the matrix Python version (e.g., python-version: ${{ matrix.python-version }}).
  • Ensure that nox sessions are compatible with all Python versions in the matrix.
  • Verify that the CI pipeline passes for all Python versions in the matrix.

Definition of Done

  • The CI pipeline runs tests against multiple Python versions (3.11, 3.12, 3.13) successfully.
  • The change is documented in CONTRIBUTING.md if necessary.
  • All nox stages pass (nox -e lint, nox -e typecheck, nox -e unit_tests, nox -e integration_tests).
  • Coverage >= 97% (nox -e coverage_report).
  • PR is merged and linked issue is closed.

Duplicate Check

  • Search Queries: matrix build, python versions, test matrix
  • Results: 0 issues found.
  • Justification: No existing issue covers the implementation of a matrix build for Python version compatibility testing.

Backlog note: This issue was discovered during autonomous operation
on milestone v3.7.0. It does not block milestone completion and has been
placed in the backlog for human review and future milestone assignment.

Issue triaged by project owner:

  • State: Verified
  • Priority: Backlog — Multi-version Python matrix builds are a quality improvement but not blocking any milestone. The project is significantly behind schedule with 878+ open issues; this is not urgent. The current single-version CI is sufficient for now.
  • Milestone: None (backlog) — This is a future enhancement for when the project stabilizes.
  • Story Points: 2 — S — Modifying the CI YAML to add a matrix strategy is a focused change, estimated 1-4 hours.
  • MoSCoW: MoSCoW/Could have — The spec does not require multi-version Python testing. This is a quality-of-life improvement for compatibility assurance. The project can ship without it.
  • Parent Epic: #5407 (as noted in the issue body)

Valid improvement but should not compete with the critical bug backlog. Keeping in backlog for future milestone assignment.
