This change introduces code from pyreq2rpm, a tested set of
requirement conversion functions used in pyp2rpm and rpm's
pythondistdeps.
This adds support for the '~=' operator and wildcards.
Pros:
- projects without pyproject.toml will have 1 less dependency
- toml will be buildable with pyproject-rpm-macros out of the box
- easier bootstrap sequence (in theory)
Cons:
- projects with pyproject.toml will have 1 more %generate_buildrequires round
In %pyproject_buildrequires, don't run python with -I but -s.
This allows projects used by the script itself, such as packaging or toml,
to be packaged using the macros, using "self" -- i.e. the code from $PWD.
%pyproject_install currently has:
`pathfix%{python3_version}.py -pni "%{__python3}" -k%{?py3_shbang_opts: -a%{py3_shbang_opts_nodash}} %{buildroot}%{_bindir}/*`
We should replace it with `%py3_shebang_fix %{buildroot}%{_bindir}/*` which expands to:
~~~~
if [ -f /usr/bin/pathfix%{python3_version}.py ]; then
pathfix=/usr/bin/pathfix%{python3_version}.py
else
# older versions of Python don't have it and must BR /usr/bin/pathfix.py from python3-devel explicitly
pathfix=/usr/bin/pathfix.py
fi
$pathfix -pni %{__python3} -k%{?py3_shebang_flags:a %py3_shebang_flags}} %{buildroot}%{_bindir}/*
~~~~
Mainly so that we:
- switch to %py3_shebang_flags
- have only one place to fix the invocation

There is a slight problem when reporting that a dependency with extra is satisfied.
In fact, we only check the "base" dependency.
This can lead to a problem when a dependency is wrongly assumed as present
and the script proceeds to the "next stage" without restarting --
if the next stage tries to use (import) the missing dependency,
the script would crash.
However, that might be a very unlikely set of events and if such case ever happens,
we'll workaround it or fix it.

- Explain what "provisional" means
- Say what kinds of projects the macros handle
- Tell people to BuidRequire python*-devel
- Say %pyproject_buildrequires is needed for the other macros
- Note that %pyproject_buildrequires generates `exit 11` messages
- Note that most buildsystems have prepare-metadata-for-build-wheel
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.

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.
- drop stuff that we don't need to test this
- use macros where possible
- use explicit test command when testing stuff
- make sure dist-info is a directory
