Previously, we have used `grep -v` to assert something is *not* there.
However, that doesn't work. See for example this file:
$ cat TEST
line1
line2
line3
$ grep -v line4 TEST
line1
line2
line3
$ echo $?
0
This gives a false sense of correctness, however it exits will 0 with anything:
$ grep -v line3 TEST
line1
line2
$ echo $?
0
Instead, we use `! grep` now:
$ ! grep line4 TEST
$ echo $?
0
$ ! grep line3 TEST
line3
$ echo $?
1
Additionally, remove a trailing slash from one of the checks to match both cases
(with or without the slash).
The PEP 517 shows an example backend-path like this:
[build-system]
# Defined by PEP 518:
requires = ["flit"]
# Defined by this PEP:
build-backend = "local_backend"
backend-path = ["backend"]
https://www.python.org/dev/peps/pep-0517/#source-trees
See that backend-path is a list. Our code previously only supported string path.
Obviously a string path is wrong, but we keep it to support projects that have
made the mistake, such as flit-core.
Add a small integration test for both cases.
Note that the new spec files deliberately don't do much, to save CI time.
An empty line happens when there are not deps:
Handling from tox --print-deps-only: <toxname>
WARNING: Skipping invalid requirement:
Parse error at "''": Expected W:(abcd...)
According to PEP 627, the RECORD file is optional and
doesn't make sense to keep it for system packages. Moreover,
its absence should indicate to other tools like pip that
they should not touch such packages.
Now, we process content of all RECORD files to one
pyproject-record (JSON) which is then used in
%pyproject_save_files. That way, we can remove the original
files in %pyproject_install and keep their content for
later.

If not checked, installing runtime requirements might fail.
When a requirement is specified in setuptools' setup_requires:
setup(
...
setup_requires=["pytest-runner"],
)
It is part of the get_requires_for_build_wheel hook output.
When runtime requirements are parsed with setuptools without all setup_requires
present, it tries to get them from the internet (at least on Fedora 33).
By checking the requirements after installing "requires_for_build_wheel",
we make sure all setup_requires are already installed.
When runtime requirements are not installed, this adds an unneeded check,
but the script would end at that point anyway, so there is no real difference.
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.
Fixes: https://bugzilla.redhat.com/show_bug.cgi?id=1868346
- 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
