I can imagine myself using this locally when some test dependencies are missing
(e.g. in RHEL). I hope it's possible to
use this with `mock --install` and not just as BuildRequires. It is not clear
from the linked GH wiki page.
I did not thought about this. Should be easy to implement. Tracked here:
https://github.com/rpm-software-management/mock/issues/671
1) Can I specify version ranges? Do I use RPM or Python syntax?
Version of module? Or version of python?
Version of the buildrequired PyPI package. E.g. "external:pypi:dnspython < 2".
(I assume this is what you've meant by "version of module".)
Python version will be whatever Python version pip is for. That's fine.
If support for multiple Python versions (e.g. for RHEL) is desired, passing
custom pip package / command needs to be supported, e.g. via
config_opts['external_buildrequires_pypi_required_packages'] and
config_opts['external_buildrequires_pypi_install_command'].
No. You cannot. Neither of them.
Can you point me to differences between RPM and Python syntax of version ranges?
It's complicated :)
See https://github.com/gordonmessmer/pyreq2rpm/ for a best-effort conversion
from Python package version specifiers to the RPM ones. The dependency generator
uses this.
2) I've read that a temporary RPM package is created:
To satisfy rpm dependencies Mock calls create-fake-rpm and creates a fake rpm
package that provides external:pypi:foo and installs it in chroot.
Does the fake RPM provide pytohn3.9dist(foo)?
No. It does not. The fake rpm is there only to provide the string
"external:pypi:*' so rpmbuild will proceed with building.
I can enhance it to provide pytohn3.9dist(foo). How can I get that 3.9 number?
I tried to look through existing macros and I tried to fiddle with
/usr/lib/rpm/pythondistdeps.py but it does not ring
the bell.
If you can get the list of files installed by pip (pip knows them), you could
run the dependency generator directly upon them.
This somehow gives the files, except you need to join Location and Files.
$ python -m pip show -f appdirs
Running the generator is:
$ echo /usr/lib/python3.9/site-packages/appdirs-1.4.3.dist-info/* | \
/usr/lib/rpm/pythondistdeps.py --provides \
--normalized-names-format pep503 --normalized-names-provide-both \
--majorver-provides-versions 2.7,3.9
python3.9dist(appdirs) = 1.4.3
python3dist(appdirs) = 1.4.3
However, since the buildrequired pypi packages can also bring in other packages,
it's not that simple.
Also, that command's options will differ from buildroot to buildroot.
Should it?
I do not know. Should? :) I think it should. As it is build requirements it is
welcomed and safe. Run time requirement
would be different case.

Thank you for the feedback.
