Description Ben Beasley 2026-03-01 08:29:45 UTC
Spec URL: https://music.fedorapeople.org/python-discovery.spec
SRPM URL: https://music.fedorapeople.org/python-discovery-1.1.0-1.fc43.src.rpm
Description: Python interpreter discovery.
Fedora Account System Username: music

This is a new package from the tox-dev organization; it was split out from virtualenv into a standalone package. It is a new dependency for the latest release of Hatch, and will probably soon be needed for other things as well.

This is a trivial pure-Python package. I’ve chosen to use the provisional pyproject declarative buildsystem; see the README at https://src.fedoraproject.org/rpms/pyproject-rpm-macros for details.

Comment 1 Fedora Review Service 2026-03-01 08:31:44 UTC
Copr build:
https://copr.fedorainfracloud.org/coprs/build/10180551
(failed)

Build log:

Please make sure the package builds successfully at least for Fedora Rawhide.

- If the build failed for unrelated reasons (e.g. temporary network
  unavailability), please ignore it.
- If the build failed because of missing BuildRequires, please make sure they
  are listed in the "Depends On" field

The build failed due to ongoing COPR infrastructure issues.

Comment 5 Ben Beasley 2026-03-02 11:04:41 UTC
> - Package contains BR: python2-devel or python3-devel

See https://docs.fedoraproject.org/en-US/packaging-guidelines/Python/#_build_time_dependency_on_python3_devel: this requirement may be satisfied by any of:

- an explicit, manual BuildRequires: python3-devel
- use of %pyproject_buildrequires (c.f. the guidelines link above, as well as https://pagure.io/packaging-committee/pull-request/1384)
- use of BuildSystem: pyproject: not explicitly mentioned in the guidelines since the declarative buildsystem remains provisional, but see discussion in https://pagure.io/packaging-committee/pull-request/1379

This package has BuildSystem: pyproject, so an explicit BuildRequires would be redundant.

> b) Consider packaging the documentation. Happy to package missing dependencies,

As a general rule, I no longer package generated documentation in Python packages. I was once a proponent of doing so, but I’ve slowly come around to the view that the value of generated offline documentation is not worth the complexity, added dependencies, and various issues associated with producing it. HTML documentation has various issues with bundled CSS, JS, fonts, etc. and their licenses. PDF documentation mostly sidesteps these, but can be fussy and brittle, and brings in heavy build dependencies on TeX Live. Your method of building documentation in texinfo format and then converting to Docbook XML is clever, appears to comply with packaging guidelines, and can be useful for those who know what to do with it. However, the result is a somewhat unusual format that people are less likely to discover or know how to read, and which needs close inspection for usefulness since it’s very unlikely to be tested by upstreams, who are in most cases exclusively targeting HTML; and the added spec-file complexity is viable, but not insignificant. Perhaps if there were a distribution-wide consensus that this was “the” way to handle Python documentation, then I might view this format as more worthwhile to produce.

> c) Should the name be python-python-discovery?

> https://pypi.org/project/discovery/

In https://docs.fedoraproject.org/en-US/packaging-guidelines/Python/#_library_naming, the guidelines now explicitly state:

> The Fedora component (source package) name for a library should be formed by taking the canonical project name and prepending python- if it does not already start with python-. This may leads to conflicts (e.g. between bugzilla and python-bugzilla). In that case, ensure upstream is aware of the potentially confusing naming and apply best judgment.

Looking at https://pypi.org/project/discovery/#history, it was first released on June 2, 2015, and the final release was just three days later. The GitHub repository linked to by the PyPI page has been removed. It’s clear not only that this now is a dead project, but also that it never really got off the ground in the first place. It’s therefore vanishingly unlikely that the “other discovery package” will ever be submitted to Fedora. Considering this, and the above prescription quoted from the guidelines, I believe that python-discovery is the correct name.

Comment 6 Benson Muite 2026-03-02 14:06:10 UTC
The company that had the project still seems to be  active:
https://github.com/zymbit/
https://docs.zymbit.com/
but yes, it sems  unless the package name is given to another project,
that it will be unlikely to become a Fedora package.

Approved.

would be appreciated if time allows.
