Reduce dependencies on python3-setuptools
Summary
We'll do two things to reduce the number of Python packages unnecessarily Requiring python3-setuptools:
- python3-devel will no longer Require python3-setuptools
- packages with console_scripts/gui_scripts entry points will no longer automatically Require python3-setuptools

Detailed Description
Historically, for over a decade, setuptools was omnipresent in Python packaging. For that reason, the python3-devel package required python3-setuptools. This is however changing, with PEP517- and PEP518-based upstream packaging, setuptools changed to a very popular yet only optional way of building packages, many upstreams switched to poetry or flit instead. Since we received multiple user reports about an unnecessary dependency, we wanted to get rid of the dependency, but it was not possible until now.
We'll do the two following changes (neither one depends on the other):
python3-devel will stop Requiring python3-setuptools
When we wanted to remove the dependency before, we have encountered a problem, which is best summarized in the Python spec file:
# This is not "API" (packages that need setuptools should still BuildRequire it) # However some packages apparently can build both with and without setuptools # producing egg-info as file or directory (depending on setuptools presence). # Directory-to-file updates are problematic in RPM, so we ensure setuptools is # installed when -devel is required. # See https://bugzilla.redhat.com/show_bug.cgi?id=1623914 # See https://fedoraproject.org/wiki/Packaging:Directory_Replacement Requires: (python3-setuptools if rpm-build)
To avoid this problem, python3-devel currently requires (python3-setuptools if rpmbuild)
for backwards compatibility.
Other than that, python3-setuptools was always brought into the buildroot transitively with python3-rpm-generators.
Since the generators no longer use setuptools but packaging we can finally remove the dependency.
Packages that don't BuildRequire python3-setuptools but use setuptools during the build will fall into one of the following three categories:
- They will fail to build from source with errors like:
ModuleNotFoundError: No module named 'setuptools'
. - They will successfully build from source because they will fallback to the standard library distutils module - their
.egg-info
directory will become a text file instead, causing errors when RPM tries to update the package (and they will possibly miss some runtime dependencies because the metadata generated by distutils is not complete). - They will continue to build unchanged because one or more packages they BuildRequire pulls in python3-setuptools transitively - at any point in the future, this can change and either (1) or (2) will happen.
We tested this change in the past when we asked other maintainers to explicitly BuildRequire python3-setuptools. Some of them responded, but many did not. Our analysis was based on grepping sources for any mention of setuptools, such as import setuptools
or from setuptools import
. Nowadays, the same grep-based query showed us roughly the same number (~350) of packages relying on python3-setuptools without BuildRequiring it. To see the direct impact, we have also briefly removed the Requires from python3-devel package used in testing python3.10 in COPR. It revealed only 140 packages that fail to build from the source because of the change, however many packages bring in python3-setuptools transitively. Some of the packages might build successfully even without python3-setuptools, because they fallback to distutils (from the Python standard library) if dependency on setuptools is not satisfied.
To avoid such problems we will:
- Mass update packages we analyzed as impacted to add the missing BuildRequires on python3-setuptools.
- Do the change while doing the update from Python 3.9 to Python 3.10 so the path of the
.egg-info
changes from/usr/lib(64)/python3.9/site-packages/...egg-info
to/usr/lib(64)/python3.10/site-packages/...egg-info
, hence no longer causing troubles on upgrades if some packages actually do change it from directory to file (and changing it the other way around in the future is safe).
How do we mass update the spec files
You can find the script we will use here. The script tries to detect what notation for BuildRequires definition each spec file uses.
Example of the most common occurrences:
BuildRequires: python%{python3_pkgversion}-setuptools BuildRequires: %{py3_dist setuptools} BuildRequires: python3-setuptools BuildRequires: python3dist(setuptools)
We will try to keep the added BuildRequires as much consistent as possible with the existing Python-related BuildRequires (including e.g. whitespace). We will not bump the release or add a changelog entry (the Python 3.10 rebuild will take care of it). To show how the proposed modifications will look like we plan to create a git repository with all the spec files and commit the change there. The diff was shared on the devel and python-devel mailing lists, so maintainers can easily see the upcoming change and can provide feedback to us. You can find changes done by the script here
When do we update the spec files
We plan to mass update the spec files in the middle of April 2021, if you wish to opt-out from the mass update, please let us know prior to 15th of April 2021.
What spec files we will update
Below is the list of packages we plan to add BuildRequires for python3-setuptools to. If you wish to opt-out of this update, please edit this page and move your package to the list of packages to be ignored (listed below this one).

Packages to be ignored
- fontforge - false positive
- gaupol - false positive: setuptools import is in setup-aeidon.py, which is unused; aeidon is instead built with setup.py using distutils only
- poetry - has the setuptools imports in integration tests only, will add the requirement to test buildrequires manually if needed
- python-poetry-core - seems like a false positive, will investigate
- qemu - false positive
- xrootd - false positive
Packages with console_scripts/gui_scripts entry points will no longer automatically Require python3.Xdist(setuptools)
Packages that use the console_scripts
or gui_scripts
entry points used to generate scripts for them that imported pkg_resources
(from setuptools) on runtime and thus all such packages needed to Require setuptools on runtime. This is an example of such generated script from Fedora 32:
#!/usr/bin/python3 # EASY-INSTALL-ENTRY-SCRIPT: 'fedpkg==1.40','console_scripts','fedpkg' __requires__ = 'fedpkg==1.40' import re import sys from pkg_resources import load_entry_point if __name__ == '__main__': sys.argv[0] = re.sub(r'(-script\.pyw?|\.exe)?$', , sys.argv[0]) sys.exit( load_entry_point('fedpkg==1.40', 'console_scripts', 'fedpkg')() )
The Python dist RPM dependency generator (/usr/lib/rpm/fileattrs/pythondist.attr
) hence generated a Requires on python3.Xdist(setuptools)
for all packages with scripts like the one above.
Starting from Python 3.8 and setuptools 47, this is no longer required, because the scripts will use importlib.metadata
from the standard library instead of pkg_resources
from setuptools. The scripts now looks like this:
#!/usr/bin/python3 # EASY-INSTALL-ENTRY-SCRIPT: 'fedpkg==1.40','console_scripts','fedpkg' import re import sys # for compatibility with easy_install; see #2198 __requires__ = 'fedpkg==1.40' try: from importlib.metadata import distribution except ImportError: try: from importlib_metadata import distribution except ImportError: from pkg_resources import load_entry_point ...
Since the scripts are generated during build, the packages no longer need to Require setuptools on runtime.
The Python dist RPM dependency generator will no longer generate the Requires on python3.Xdist(setuptools)
.
The change is prepared in a pull request (https://src.fedoraproject.org/rpms/python-rpm-generators/pull-request/38). We plan to merge it as soon as it is ready. It only changes the behavior for Python 3.10 or newer, hence it will take affect in the Python 3.10 copr only, until Python is updated to 3.10 in Fedora proper.
Packages that actually import from the setuptools
or pkg_resources
module on runtime should explicitly require setuptools, but some of the upstreams may not do that. We don't expect many packages negatively affected by this, but since this is not strictly backwards compatible, we are only planning to do it in Fedora 35+.

Benefit to Fedora
From Fedora Packaging Guidelines: It is important that your package list all necessary build dependencies using the BuildRequires: tag. As our testing showed, this is not true for many packages. Some of them can successfully build either with or without setuptools (they use try-except import and fallback to distutils from the standard library). Such packages are especially dangerous when not BuildRequiring setuptools -- they can produce different results depending on the presence of setuptools: either an .egg-info metadata directory (w/setuptools) or .egg-info text file (w/distutils). RPM has troubles when upgrading directories to files.
More Python applications will be installable without setutpools, hence contributing to the general minimization objective.
Scope
Some packages use distutils as a fallback in case setuptools is unavailable. The problem is that setuptools generates egg.info directory and distutils creates egg.info file. This would lead to failures caused by the known issue of RPM that cannot change directory to file. To avoid this we plan to do a mass spec update before we upgrade Python to version 3.10. This way we ensure that path will be correct after the mass rebuild.
- Proposal owners:
- Test affected packages in Copr.
- Do the mass spec update to introduce missing BuildRequire to them.
- Other developers: If your package requires setuptools on runtime, make sure it specifies it explicitly. There should be no additional work for developers other than that. There is a possibility that some packages will slip through our grep based query and fail to build, but we'll detect this in our testing Copr and fix them.
- Release engineering: not needed for this Change
- Policies and guidelines: already exist
- Trademark approval: not needed for this Change
- Alignment with Objectives: minimization
Upgrade/compatibility impact
All affected packages needs rebuild after the mass spec update but since we plan to do it with the upgrade to Python 3.10 we will rebuild it altogether. Users should not be affected by upgrades in any way.
How To Test
Interested testers can push explicit BuildRequire on setuptools to the distgit and see in our Python 3.10 COPR whether the package starts to build again. Webhook should trigger rebuild automatically on new commit in rawhide branch.
User Experience
Regular distro users shouldn't notice any change in system behaviour, except for packages that use setuptools or pkg_resources on runtime and fail to specify that dependency. Such packages will fail to run with ModuleNotFoundErrors and should be fixed by their maintainers.
Dependencies
300+ packages will need to BuildRequire setuptools explicitly. This will be done by the mass spec update.
Contingency Plan
- Contingency mechanism: Commit removing python3-devel Requires on
(python3-setuptools if rpmbuild)
will be reverted. The change in Python dist RPM dependency generator will be reverted (Each of the contingency mechanisms can be applied independently.) - Contingency deadline: mass rebuild
- Blocks release? No
