chore: Map a declared license for PyPI::pytest-cov

[brunopacheco1]

The library is licensed under MIT, but according to
this Pull Request,
the project metadata was mistakenly stating BSD License.
All versions below 2.12.0 are impacted by this issue.
Current (4.1.0) license: https://github.com/pytest-dev/pytest-cov/blob/2c9f2170d8575b21bafb6402eb30ca7de31e20b9/LICENSE
Current project metadata: https://github.com/pytest-dev/pytest-cov/blob/2c9f2170d8575b21bafb6402eb30ca7de31e20b9/setup.py
License at 2.12.0: https://github.com/pytest-dev/pytest-cov/blob/9692bad8c3501b77cf950d0732ae9cb5c8bb0bd4/LICENSE
Project metadata at 2.12.0: https://github.com/pytest-dev/pytest-cov/blob/9692bad8c3501b77cf950d0732ae9cb5c8bb0bd4/setup.py
License before 2.12.0: https://github.com/pytest-dev/pytest-cov/blob/5e1913e013eb06d5bd1357695349d0a75fbf0503/LICENSE
Project metadata before 2.12.0: https://github.com/pytest-dev/pytest-cov/blob/5e1913e013eb06d5bd1357695349d0a75fbf0503/setup.py

That's an interesting case. What's your take on this @willebra? Does this really make past releases MIT- instead of BSD-licensed?

PS: I've asked the maintainers to be explicit on that.

[willebra]

@sschuberth I think this looks quite a genuine error at the project side, and I don't have doubts based on the history and the linked commits. The license-file has remained MIT all the time. And setup.py had internally conflicting statements in history, i.e. MIT and BSD License statements, both at the same time, prior to the correction. After correction, it is MIT in every place.

Also any risk is quite low, considering the very similar obligations of these licenses, of course the BSD-ststement has been quite vague.

I could treat all the historical versions also as MIT.

Please make this a full, clickable link. And better link the PR, which has some additional background information, i.e https://github.com/pytest-dev/pytest-cov/pull/467.

Done.

[sschuberth]

I was meaning to actually replace the link with only the link to the PR, which already contains the diff for the commit, so there is not need to link the commit as well.

Ah, yes, no problem, just fixed the commit.
