[SOLVED] Python packaging with setuptools - easy_install vs. pip

A user has encountered a problem with one of my python pacakges in the AUR.
After some tinkering, I finally was able to reproduce this issue in my build environment.
It seems, that, if python-pip is not installed, distutils falls back to easy_install to setup the python package and builds it just fine:

$ makechrootpkg -cr /var/build

In the Wiki, however, the guidelines suggest to refrain from using pip.
So I am uncertain how to correctly specify the build dependencies in the package?
PKGBUILD does not provide something like "makeconflicts" where I could add python-pip to force distutils to fall back to easy_install.
Consequentially I suspect, that I am doing something wrong regadring my package setup, but I cannot see what it might be.
Am I to add python-pip and python-wheel as dependencies or do I somehow need to rewrite my package() function?
What's the recommended way to go here?

Re: [SOLVED] Python packaging with setuptools - easy_install vs. pip

This is an easy one to solve. Your setup.py requires the use of this pypi module: https://pypi.org/project/setuptools-git-version/

But you have a makedepends on the Arch community package for this one: https://pypi.org/project/setuptools-git/

This is obviously terribly broken -- the PKGBUILD does not install the needed makedepends, so the python build system tries to download it unchecksummed over the internet in order to make use of it. In various circumstances it tries different things, too...

The number of different modules performing the exact same "get a version number by executing git describe" is astounding. They breed like rabbits.

What's even the point of all this? Much better to use tarball sources and have a trivial release rule to update setup.py with the version. Or even better, migrate to setup.cfg: https://setuptools.readthedocs.io/en/la … ing-values (note "attr:" and "file:" directives. Then you could set the version number from the common convention of the program's internal __version__ value in __init__.py (unless of course your program doesn't know its version when running progname --help of course).

Re: [SOLVED] Python packaging with setuptools - easy_install vs. pip

Thank you for your review and the suggestions.
The discrepancy between the git package required and actually used, made me actually facepalm.

The reason I'm using such a thing in the first place is, that I have had bad experience with manual version tracking.
Manually updating the version has proven to be error prone, since I frequently forget to update it in all necessary places on a version bump i.e. new release.
I found that just adding an appropriate git tag and let software do the magic for me is more reliable, but I am open for new suggestions.

My software also does not know about its version. I never found that to be useful, since this was one of those places, where I frequently forgot to bump the version number, so that there would be an actual discrepancy between the package version and the version the program reports.
If a user wants to know the version of my python packages, they can ask pacman or pip respectively.

Another reason that I use the versioning automation is, that I use the same PKGBUILD base for all my python packages, some of which I also publish on pypi, since they are not Arch-specific (unlike speculum, of course).
So to update a package on PyPI I can just run "make pypi" (see Makefile) and after providing my credentials, it will also update the package on the PyPI to the latest tagged version.

If you think that this is an unfeasible approach, I am open to suggestions. I however would like to have the option to just update the package version in one place only, preferably in the git tags.

PS: The community package setuptools-git does not provide the versioning magic, that setuptools-git-version provides.
Luckily I just found python-setuptools-scm, which seems to work nicely on first tests.

Re: [SOLVED] Python packaging with setuptools - easy_install vs. pip

Ah, well, there's definitely a bunch of modules to do it even if setuptools-git isn't one of them. tongue

Anyway, the nice thing about setup.cfg attributes is, like I said, you can use one file in your repository to track this info for multiple uses. I honestly don't see the point of deferring to git describe though. Just add a Makefile rule that bumps both at the same time. There are also a few different python projects to do this for you specific to bumping version strings everywhere in your codebase.
