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}
