Mauro says:
This series increases the minimal requirements for Sphinx and Python, and
drop some backward-compatible code from Sphinx extension.
Looking at Sphinx release dates:
Release 2.4.0 (released Feb 09, 2020)
Release 2.4.4 (released Mar 05, 2020) (current minimal requirement)
Release 3.4.0 (released Dec 20, 2020)
Release 3.4.3 (released Jan 08, 2021)
(https://www.sphinx-doc.org/en/master/changes/index.html)
And Python release dates, we have:
Python Release date
3.5 2015-09-13 (current minimal requirement)
3.6 2016-12-23
3.7 2018-06-27
3.8 2019-10-14
3.9 2020-10-05
3.10 2021-10-04
(according with https://en.wikipedia.org/w/index.php?title=History_of_Python)
The new minimal requirements are now compatible with the toolset available on Jan, 2021,
e.g.:
- Sphinx 3.4.3;
- Python 3.9
The new Sphinx minimal requirement allows dropping all backward-compatible code
we have at kernel-doc and at Sphinx extensions.
The new Python minimal requirement also matches the current required level for
almost all scripts (*).
Those matches a 4-years old toolchain, which sounds a reasonable period
of time, as Python/Sphinx aren't required for the Kernel build.
(*) Except for a couple scripts inside tools that require python 3.10:
$ vermin -v $(git ls-files '*.py')|grep 3.10
!2, 3.10 tools/net/sunrpc/xdrgen/generators/__init__.py
!2, 3.10 tools/net/sunrpc/xdrgen/generators/program.py
!2, 3.10 tools/net/sunrpc/xdrgen/subcmds/source.py
!2, 3.10 tools/net/sunrpc/xdrgen/xdr_ast.py
!2, 3.10 tools/perf/scripts/python/mem-phys-addr.py
!2, 3.10 tools/power/cpupower/bindings/python/test_raw_pylibcpupower.py
Such scripts aren't required for Kernel builds, so it should be OK to set minimal
python version to 3.9.
