This test was previously skipped because we didn't have new enough tox.
That's why it was never fixed for setuptools 70+.
This is a fixup for 20b7ac63f3
Keep the information about the requirement extras by storing the
Requirement instances in the list of the ignored requirements, rather
than the strings in the form they were initially read from metadata.
The requirements strings read from pyproject.toml don't contain the
extra information, we insert the extra marker only after converting them to
Requirement instances. When stored as the text, the information about
the extra went missing in the course of the script.
This adds a new flag, -p, to %pyproject_buildrequires.
When set, the runtime dependencies are read from the pyproject.toml's
[project] table.
See: https://bugzilla.redhat.com/2261939
pyproject_buildrequires.py already had a short `-p` option for
--python3_pkgversion (hidden from the macro users).
This change removes the one-letter option and leaves the long-one.
`-p` is now reused for reading dependencies from pyproject.toml
and made visible to the macro users.
This makes the tests work on EL 9 and Fedora 36.
- Move metadata to setup.cfg in self-referential extras tests
- Skip tests for pyproject.toml [project] metadata when setuptools < 60
Dependencies are recorded to a text file that is catted at the end.
This should prevent subtle bugs like https://bugzilla.redhat.com/2183519 in the future.
When the build backend prints to stdout via non-Python means,
for example when a setup.py script calls a verbose program via os.system(),
the output leaked to stdout of %pyproject_buildrequires was treated as generated BuildRequires.
Fore example, if the setup.py script has:
rv = os.system('/usr/bin/patch -N -p3 -d build/lib < lib/py-lmdb/env-copy-txn.patch')
(From https://github.com/jnwatson/py-lmdb/blob/py-lmdb_1.0.0/setup.py#L117)
The stdout of /usr/bin/patch leaked to stdout of %pyproject_buildrequires:
[lmdb-1.0.0]$ /usr/bin/python3 -Bs /usr/lib/rpm/redhat/pyproject_buildrequires.py --python3_pkgversion 3 2>/dev/null
python3dist(setuptools) >= 40.8
python3dist(wheel)
patching file lmdb.h
patching file mdb.c
python3dist(wheel)
patching file lmdb.h
patching file mdb.c
This resulted in DNF errors like this:
No matching package to install: 'lmdb.h'
No matching package to install: 'mdb.c'
No matching package to install: 'patching'
Moreover, it resulted in bogus BuildRequires that may have existed (e.g. "file").
By replacing the usage of contextlib.redirect_stdout
(which only redirects Python's sys.stdout)
with a custom context manager that captures stdout on file descriptor level
(in addition to Python's sys.stdout),
we avoid this leak.
File descriptor magic heavily inspired by the capfd pytest fixture.

Improve handling of > operator, preventing post-release from satisfying most rpm requirements.
Improve handling of < operator, preventing pre-release from satisfying rpm requirement.
Improve handling of != operator with prefix matching, preventing pre-release from satisfying rpm requirements.
%pyproject_buildrequires macro now accepts multiple file names to load
additional dependencies from them.
New option -N was added to disable automatical generation of requirements
in case package does not use build system. Option -N cannot be used in
combination with options -r, -e, -t, -x.

The macro checks if pyproject.toml exists and echoes the dependency early.
For projects with pyproject.toml, this saves one installation round.
Previously, the installation steps by %generate_buildrequires were:
1. (python3-devel +) pip + packaging
2. toml
3. parsed dependencies from pyproject.toml
4. ...
Now they are:
1. (python3-devel +) pip + packaging + toml
2. parsed dependencies from pyproject.toml
3. ...
For projects without pyproject.toml, the number of rounds remains the same:
1. (python3-devel +) pip + packaging
2. setuptools + wheel
3. ...
This is also more consistent:
The Python script now only outputs dependencies of the probed project,
it no longer partially outputs dependencies for itself.
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
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.
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}
