Hi Jon,
that's the second version of the patch series which converts
sphinx-pre-install to Python.
The core patches are basically the same as on v1, but it has lots of
fixes over the original script after testing sphinx-install on 22
distros.
Please notice that I have a separate patch series addressing issues
that are specific to PDF generation.
Test Results Summary:
====================
PASSED - AlmaLinux release 9.6 (Sage Margay) (4 tests)
PASSED - Amazon Linux release 2023 (Amazon Linux) (4 tests)
PASSED - Arch Linux (4 tests)
PASSED - CentOS Stream release 9 (4 tests)
PASSED - Debian GNU/Linux 12 (4 tests)
PASSED - Devuan GNU/Linux 5 (4 tests)
PASSED - Fedora release 42 (Adams) (4 tests)
PASSED - Gentoo Base System release 2.17 (4 tests)
PASSED - Kali GNU/Linux 2025.2 (4 tests)
PASSED - Mageia 9 (4 tests)
PASSED - Linux Mint 22 (4 tests)
PASSED - openEuler release 25.03 (4 tests)
PARTIAL - OpenMandriva Lx 4.3 (4 tests)
ensurepip package doesn't exist there. So, venv install failed.
Installed via package worked
PASSED - openSUSE Leap 15.6 (4 tests)
PASSED - openSUSE Tumbleweed (4 tests)
PASSED - Oracle Linux Server release 9.6 (4 tests)
FAILED - Red Hat Enterprise Linux release 8.10 (Ootpa) (4 tests)
I couldn't test properly, as it requires a repository under
paywall. I suspect It should work fine
PARTIAL - Rocky Linux release 8.9 (Green Obsidian) (4 tests)
Install via package didn't work. Instaling via venv works.
PASSED - Rocky Linux release 9.6 (Blue Onyx) (4 tests)
PARTIAL - Springdale Open Enterprise Linux release 9.2 (Parma) (4 tests)
Failed to install ImageMagick (affects pdf only)
PASSED - Ubuntu 24.04.2 LTS (4 tests)
PASSED - Ubuntu 25.04 (4 tests)
In short, I expect that, for all the above, the script will properly
recommend the right packages to have sphinx-build working.
A more detailed list of tests that passed/failed and detected Sphinx
versions can be seeing below:

The minimal version requirements we have is 3.9. Yet, the
script which detects it is this one. So, let's try supporting
an old version here, as we may want to suggest to upgrade
Python version to build the docs.

The scripts/sphinx-pre-install is used to detect problems at
the system environment and adjust it to build the Kernel
documentation. If the version is too old, it won't run, though.
Check if the version which started the script is valid. If not,
seek for a new one that is compatible with documentation
build.

Up to Python 3.2, the virtual environment were created
via virtualenv binary.
As we dropped support for such old version, clean up the code.

On openSUSE Leap 15.6, which is the current LTS version, has two
Sphinx packages. The normal one requires Python 3.6, which we
don't support anymore. However, it also has Python 3.11 with a
newer Sphinx version (7.2.6).
Suggest the newer version:
Detected OS: openSUSE Leap 15.6.
ERROR: at least python 3.7 is required to build the kernel docs
Warning: python version is not supported.
Warning: better to also install "convert".
Warning: better to also install "dot".
ERROR: please install "yaml", otherwise, build won't work.
You should run:
sudo zypper install --no-recommends ImageMagick graphviz python311-pyyaml
Sphinx needs to be installed either:
1) via pip/pypi with:
Currently not possible.
Please upgrade Python to a newer version and run this script again
2) As a package with:
sudo zypper install --no-recommends python311-Sphinx
Please note that Sphinx >= 3.0 will currently produce false-positive
warning when the same name is used for more than one type (functions,
structs, enums,...). This is known Sphinx bug. For more details, see:
https://github.com/sphinx-doc/sphinx/pull/8313
Can't build as 2 mandatory dependencies are missing

Rhel < 8.0 is not supported anymore. Drop support for it.
Rhel 8 is problematic: at least on the tests I did with a
docker repo, it didn't work, but it could be due to the issue
that it is actually different than a real One.

I forgot one f-string marker, with turned to be affecting 3
lines, because of cut-and-paste ;-)
Use the proper f-string marker to print Sphinx version at
the hint lines. Yet, we don't want to print as a tuple, so
call ver_str() for it.
Ideally, we would be placing it directly at the f-string, but
Python 3.6 f-string support was pretty much limited. Only
3.12 (PEP 701) makes it similar to Perl, allowing expressions
inside it. It sounds that function call itself was introduced
on 3.7.
As we explicitly want this one to run on 3.6, as latest Leap

There is a test logic meant to be for Leap, renaming rsvg-convert
package. Well, at least on latest Leap releases, this is wrong,
causing install to fail. Drop it.

According with its website: https://scientificlinux.org/
Scientific Linux reached end of life in June 30, 2024.
Also, it was based on RHEL 7, which is not compatible with
our build system anymore.
So, drop support for it.

It took me a lot of time, but I guess understand now what it
takes to install a package on Gentoo.
Handling dependencies is a nightmare, as Gentoo refuses to emerge
some packages if there's no package.use file describing them.
To make it worse, compilation flags shall also be present there
for some packages. If USE is not perfect, error/warning messages
like those are shown:
gnome-base/librsvg dev-texlive/texlive-xetex media-fonts/dejavu dev-python/pyyaml
...
!!! The following binary packages have been ignored due to non matching USE:
=media-gfx/graphviz-12.2.1-r1 X pdf -python_single_target_python3_13 qt6 svg
=media-gfx/graphviz-12.2.1-r1 X pdf python_single_target_python3_12 -python_single_target_python3_13 qt6 svg
=media-gfx/graphviz-12.2.1-r1 X pdf qt6 svg
=media-gfx/graphviz-12.2.1-r1 X pdf -python_single_target_python3_10 qt6 svg
=media-gfx/graphviz-12.2.1-r1 X pdf -python_single_target_python3_10 python_single_target_python3_12 -python_single_target_python3_13 qt6 svg
=media-fonts/noto-cjk-20190416 X
=app-text/texlive-core-2024-r1 X cjk -xetex
=app-text/texlive-core-2024-r1 X -xetex
=app-text/texlive-core-2024-r1 -xetex
=dev-libs/zziplib-0.13.79-r1 sdl
If emerge is allowed, it will simply ignore the above packages,
creating an incomplete installation, which will later fail when
one tries to build docs with images or build PDFs.
After the fix, command line commands to produce the needed USE
chain will be emitted, if they don't exist yet.
sudo su -c 'echo "media-gfx/graphviz" > /etc/portage/package.use/graphviz'
sudo su -c 'echo "media-gfx/imagemagick" > /etc/portage/package.use/imagemagick'
sudo su -c 'echo "media-libs/harfbuzz icu" > /etc/portage/package.use/media-libs'
sudo su -c 'echo "media-fonts/noto-cjk" > /etc/portage/package.use/media-fonts'
sudo su -c 'echo "app-text/texlive-core xetex" > /etc/portage/package.use/texlive'
sudo su -c 'echo "dev-libs/zziplib sdl" > /etc/portage/package.use/zziblib'
The new logic tries to be smart enough to detect for missing files
and missing arguments. Yet, as Gentoo seems to require users to
manage those package.use files by hand, the logic isn't perfect:
users may still need to verify for conflicts on different use
files.

Currently, if Python < 3.7, package install will fail. That happens
with OpenSuse Leap and RHEL-based ver 8 distros.
OpenSuse allows installing Sphinx with Python 3.11, but RHEL-based
distros don't.
Prepare to recomend only venv on such cases. For now, just split
the recomendation on a new function that will check for a
paramtere to be called.

When is_optional was added in Perl, it was a boolean. With
time, it ended becoming a sort of enum, which makes the
module harder to maintain.
Convert it to a enum-like class and add more options to it.

Better implement support for RHEL-based distros. While here,
get rid of a Fedora 28 support which cause troubles with
server distros. Also, get rid of yum, as RHEL8 already
suppords dnf, and this is not the minimal version we may
still support.

The code there are just a bunch of static functions that are used by
the main class. group them altogether to better organize the code.

Better organize the code by moving the more generic methods
to MissingCheckers. Such class contain only binary and package
dependent missing checkers, but no distro-specific data or code.
All distro-specific data/code remains at SphinxDependencyChecker
class.

The code at get_system_release() is actually a helper function,
independent from the actual Sphinx verification checker. Move
it to MissingCheckers class, where other checkers are present.
With that, the entire distro-specific handler logic, with
all its complexity is confined at SphinxDependencyChecker
class.

This program is somewhat complex. Add some docstring documentation,
explaining what each function and class is supposed to do.
Most of the focus here were to describe the ancillary functions used
to detect dependency needs.
The main SphinxDependencyChecker still requires a lot of care,
and probably need to be reorganized to clearly split the 4 types
of output it produces:
- Need to upgrade Python binary;
- System install needs;
- Virtual env install needs;
- Python install needs via system packages, to run Sphinx
natively.
Yet, for now, I'm happy of having it a lot better documented
than its Perl version.
-
While here, rename a parameter to have its usage better
documented.
No functional changes.

While nothing was really needed for virtualenv to work on most
distros, we had an issue with OpenMandriva.
While checking for it, it was noticed that there was no check if
python-virtualenv was installed.
This didn't solve the issues we faced there: at least with
the half-broken OpenMandriva Lx 4.0 docker container we used,
ensurepip was not available anywhere, causing venv to fail.
Add a distro-specific note about that.
Note: at least at the time we did our tests, OpenMandriva Lx 4.0
docker was shipped with wrong dnf repositories. Also, there
was no repos available for it anymore. So, we had to do some
hacks to upgrade to 4.3 before being able to run any tests.

Whee ... I've applied the set, thanks.
