Package Review
==============

Legend:
[x] = Pass, [!] = Fail, [-] = Not applicable, [?] = Not evaluated
[ ] = Manual review needed


Issues:
=======
- Package installs properly.
  Note: Installation errors (see attachment)
  See: https://docs.fedoraproject.org/en-US/packaging-guidelines/

  The actual error looks like:
  Error:
   Problem: conflicting requests
     - nothing provides python3.9dist(mypy) = 0.790 needed by
python3-build+typing-0.1.0-2.fc34.noarch

  This is because the typing extension requires mypy==0.790. Consider something
  like this in %prep:

    # Loosen exact-version mypy requirement for typing extra:
    sed -r -i 's/(mypy)==/\1>=/' setup.cfg

  Note that only Fedora 34 provides a mypy >= 0.790. If you want to package for
  older Fedoras, you need to lower or eliminate the minimum version and then
  test it. For example:

    # Drop exact-version mypy requirement for typing extra
    sed -r -i 's/(mypy)==.*/\1/' setup.cfg

  If you do that (and maybe if you don’t) you could change 
    %pyproject_buildrequires -x test
  to
    %pyproject_buildrequires -x test,typing
  and then, in %check:

    %{python3} -m mypy %{buildroot}%{python3_sitelib}/{pypi_name}

  to verify it works as expected.

- Once you do the above, you will get an error from mypy like:

    Module 'importlib' has no attribute 'metadata'

  I have filed an upstream bug https://github.com/pypa/build/issues/211 and
  attached a patch corresponding to my accepted PR
  https://github.com/pypa/build/pull/213.

- You can build the docs even without the furo theme.
    %pyproject_buildrequires -x test,typing,doc
  and in %prep,
    # Build docs with alternative theme since python-furo is not packaged
    # (https://bugzilla.redhat.com/show_bug.cgi?id=1910798):
    sed -r -i "s/(html_theme[[:blank:]]*=[[:blank:]]*['])furo'/\1alabaster'/" \
        docs/source/conf.py
    sed -r -i '/^[[:blank:]]*furo[[:blank:]]*$/d' \
        setup.cfg docs/requirements.txt
  then add the appropriate -doc subpackage.

- The %python_provides macro is obsolete. Remove it entirely; or, if you are
  packaging for Fedora 32, you may replace it with:

    # Obsolete after Fedora 32 EOL:
    %py_provides python3-%{pypi_name}

  See:
 
https://docs.fedoraproject.org/en-US/packaging-guidelines/Python/#_the_py_provides_macro

  EPEL does need python_provides, but lacks support for the
  pyproject-rpm-macros, so I know you are not targeting it with this spec file.

- You should run the test suite by adding the following under the %check
section:

    %tox

  For the generated BR’s, you will now need:

    %pyproject_buildrequires -t -x typing,doc

  to get the BR’s from the tox configuration, and to include tox itself.

  You will have to skip one test. I am honestly not sure what is going on here.
