%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.

This allows users to do:
%build
cd somewhere
%pyproject_wheel
cd -
cd somewhere_else
%pyproject_wheel
cd -
%install
%pyproject_install
Without a need to copy paste the wheels to a common location.
This is in fact a breaking change, I'll make sure to adapt the affected packages in Fedora.
The macro already checks if pyproject.toml exists and echoes the dependency
on python3dist(toml) early. This adds an else branch to echo the default backend.
For projects without pyproject.toml, the number of installation rounds
is reduced. Previously:
1. (python3-devel +) pip + packaging
2. setuptools + wheel
3. ...
Now:
1. (python3-devel +) pip + packaging + setuptools + wheel
2. ...
This duplicates the information about the default build backend,
because the script still needs to handle projects with pyproject.toml without
an explicit build backend option.
Hence, the script was not adapted (except a comment).
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 is done to avoid troubles with %lang files listed as duplicated.
1. It gets rid of a warning
2. It fixes a problem described in:
http://lists.rpm.org/pipermail/rpm-list/2020-November/002041.html
This is a backwards incompatible change,
packages that rename or remove the installed files after %pyproject_install
might no longer be compatible with %pyproject_save_files.
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.
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.
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.
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.
