Tox calls socket.getfqdn() and that call does a DNS query.
In mock with disabled networking, it takes a minute until that times out.
When a spec file uses %pyproject_buildrequires -t and %tox, it is a 3 minute delay.
Since 3.17, tox does not call socket.getfqdn() when HOSTNAME variable is set to a value:
https://github.com/tox-dev/tox/pull/1616
The value is only used in result log, so setting it to "rpmbuild"
actually makes the logs more reproducible as well.
Fixes https://bugzilla.redhat.com/show_bug.cgi?id=1856356
when tox is used in %pyproject_buildrequires -t or %tox.
With changes in PEP 610 there is new file direct_url.json created, since it is not useful
for us we prevent it's creation. This commit changes %pyproject_install macro to install wheel using
name instead of path.
This commit also includes new test to check if file direct_url.json wasn't created.
https://discuss.python.org/t/pep-610-usage-guidelines-for-linux-distributions/4012
This macro save generates file section to %pyproject_files. It should
simplify %files section and allow to build by some automatic machinery
Supposed use case in Fedora:
%install
%pyproject_install
%pyproject_save_files requests _requests
%files -n python3-requests -f %{pyproject_files}
%doc README.rst
%license LICENSE
Automatic build of arbitrary packages (e.g. in Copr):
%install
%pyproject_install
%pyproject_save_files * +bindir // save all modules with executables
%files -n python3-requests -f %{pyproject_files}

Falling back to setuptools.build_meta:__legacy__ is the standard behavior,
not setuptools.build_meta. See PEP 517:
https://www.python.org/dev/peps/pep-0517/
> If the pyproject.toml file is absent, or the build-backend key is missing,
> the source tree is not using this specification, and tools should revert
> to the legacy behaviour of running setup.py (either directly, or by
> implicitly invoking the setuptools.build_meta:__legacy__ backend).
Falling back to setuptools.build_meta had very similar results so far.,
but the behavior might change in the feature.
While working on this, I have uncovered a problem in our code.
It was not able to handle backends with ":". Looking at PEP 517 again:
> build-backend is a string naming a Python object that will be used to
> perform the build. This is formatted following the same module:object syntax
> as a setuptools entry point. For instance, if the string is "flit.api:main",
> this object would be looked up by executing the equivalent of:
>
> import flit.api
> backend = flit.api.main
>
> It's also legal to leave out the :object part, e.g.
>
> build-backend = "flit.api"
>
> which acts like:
>
> import flit.api
> backend = flit.api
We now handle such cases properly. Witch the change of the default backend,
we also test a backend with colon in our tests.
Previously, it wasn't possible to see why tox failed:

The `rm -v` command prints the output to stderr, polluting the generated buildrequires
$ rm -rfv pytest_harvest.dist-info/
removed 'pytest_harvest.dist-info/METADATA'
removed 'pytest_harvest.dist-info/LICENSE'
removed 'pytest_harvest.dist-info/top_level.txt'
removed 'pytest_harvest.dist-info/entry_points.txt'
removed directory 'pytest_harvest.dist-info/'
This can lead to RPM errors:
error: Dependency tokens must begin with alpha-numeric, '_' or '/': 'pytest_harvest.dist-info/METADATA'
Or bogus dependencies -- the SRPM requires "removed" and "directory".
