Detailed Description

python3-devel currently requires python3-setuptools if rpmbuild is used. This was needed for RPM generators but since it adapted packaging, this is not needed anymore hence we are removing it. We tested this change in the past when we asked other maintainers to explicitly BuildRequire python-3setuptools. Some of them responded, some not. Our analysis was based on greping 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 (about 335 + 72 that failed to be analysed) of packages relying on python3-setuptools. To see direct impact we removed this Require from python-devel package used in testing python3.10 COPR. It showed us 140 packages affected by this change. Even though it is fewer than expected 300+ packages, to avoid any breakages we plan to do a mass spec update on all of them to explicitly BuildRequire python3-setuptools. Some of them might build because they fallback to distutils if dependency on python3-setuptools is not satisfied.

Below is the list of packages we plan to update with mass spec rebuild. 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.

Feedback

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.

Scope

We will coordinate the work in a side tag and merge when ready.

Proposal owners:
1. Test affected packages in Copr.
2. Do the mass spec update to introduce missing BuildRequire to them.

Other developers: There should be no additional work for other developers. BuildRequiring setuptools might not be enough for all packages, but we will take care of them manually if it happens.

Release engineering: #Releng issue number

Policies and guidelines: N/A (not needed for this Change)

Trademark approval: N/A (not needed for this Change)

Alignment with Objectives: N/A

Upgrade/compatibility impact

All affected packages needs rebuild after the mass spec update.

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.

Dependencies

140 packages will need to BuildRequire setuptools explicitly. This will be done by the mass spec update.

Contingency Plan

Contingency mechanism: Commit removing Requires on python-setuptools will be reverted.
Contingency deadline: mass rebuild
Blocks release? No
