Detailed Description

pytest-runner has been considered deprecated upstream since 2019 and the repo upstream was archived over a year ago (December 3, 2023).

Per upstream,

pytest-runner depends on deprecated features of setuptools and relies on features that break security mechanisms in pip. For example setup_requires and tests_require bypass pip --require-hashes. See also https://github.com/pypa/setuptools/issues/1684.

How to migrate to pytest

• Remove 'pytest-runner' from your 'setup_requires', preferably removing the setup_requires option.
• Remove 'pytest' and any other testing requirements from 'tests_require', preferably removing the setup_requires option.
• See our guidelines for how to specify test dependencies
• Invoke tests with pytest
• Another good option is to configure a tox.ini next to your setup.cfg. https://tox.readthedocs.io/en/latest/

Benefit to Fedora

The security benefits mostly do not apply to us, as we install dependencies from RPM packages. But preventing additional packages from depending on a package with a dead upstream that might increasingly become incompatible with newer setuptools releases would avoid us accumulating tech debt and having to deal with potential test runner failures in the future.

Scope

• Proposal owners:
  • Mark python-pytest-runner as deprecated in rawhide
  • Send PRs to affected packages to remove dependencies on this package
• Other developers:
  • If your package depends on {{package|python-pytest-runner}, adjust it to drop the dependency
• Release engineering: no impact anticipated

• Policies and guidelines: N/A (not needed for this Change)

• Trademark approval: N/A (not needed for this Change)

• Alignment with the Fedora Strategy: N/A

Upgrade/compatibility impact

N/A. This just deprecates the package, and stops it from being used in new dependencies.

Do you require 'QA Blueprint' support? N
