* docs: drop the version constraints for sphinx and dependenciesLukas Bulwahn2024-03-031-5/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As discussed (see Links), there is some inertia to move to the recent Sphinx versions for the doc build environment. As first step, drop the version constraints and the related comments. As sphinx depends on jinja2, jinja2 is pulled in automatically. So drop that. Then, the sphinx-pre-install script will fail though with: Can't get default sphinx version from ./Documentation/sphinx/requirements.txt at ./scripts/sphinx-pre-install line 305. The script simply expects to parse a version constraint with Sphinx in the requirements.txt. That version is used in the script for suggesting the virtualenv directory name. To suggest a virtualenv directory name, when there is no version given in the requirements.txt, one could try to guess the version that would be downloaded with 'pip install -r Documentation/sphinx/requirements.txt'. However, there seems no simple way to get that version without actually setting up the venv and running pip. So, instead, name the directory with the fixed name 'sphinx_latest'. Finally update the Sphinx build documentation to reflect this directory name change.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The 'alabaster' theme dropped support for Sphinx < v3.4: 0.7.14 – 2024-01-08 * Dropped support for Python 3.8 and earlier. * Dropped support for Sphinx 3.3 and earlier. [...] (Source: https://alabaster.readthedocs.io/en/latest/changelog.html) This manifests as an error when running 'make htmldocs' in a virtualenv constructed from Documentation/sphinx/requirements.txt: Sphinx version error: The alabaster extension used by this project needs at least Sphinx v3.4; it therefore cannot be built with this version. Raising the Sphinx version is not really a good option at this point, since 3.x through 6.x have horrible performance regressions (7.x still does, but not quite as bad). Instead, constrain the 'alabaster' package to versions that still support Sphinx 2.4.4.

|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit f061c9f7d058 ("Documentation: Document each netlink family") added a new Python script that is invoked during 'make htmldocs' and which reads the netlink YAML spec files. Using the virtualenv from scripts/sphinx-pre-install, we get this new error wen running 'make htmldocs': Traceback (most recent call last): File "./tools/net/ynl/ynl-gen-rst.py", line 26, in <module> import yaml ModuleNotFoundError: No module named 'yaml' make[2]: *** [Documentation/Makefile:112: Documentation/networking/netlink_spec/rt_link.rst] Error 1 make[1]: *** [Makefile:1708: htmldocs] Error 2 Fix this by adding 'pyyaml' to requirements.txt. Note: This was somehow present in the original patch submission: <https://lore.kernel.org/all/20231103135622.250314-1-leitao@debian.org/> I'm not sure why the pyyaml requirement disappeared in the meantime.

| | | | | | | | | | | | | | | jinja2 release 3.1.0 (March 24, 2022) broke Sphinx<4.0. This looks like the result of deprecating Python 3.6. It has been tested against Sphinx 4.3.0 and later. Setting an upper limit of <3.1 to junja2 can unbreak Sphinx<4.0 including Sphinx 2.4.4.

| | | | | | | | | | | | | | | | | | sphinx_rtd_theme 0.5.2 has "docutils<0.17" in its requirements. docutils 0.17 released this April caused regression in sphinx_rtd_theme 0.5.1 [1]. By removing docutils and moving sphinx_rtd_theme before Sphinx in requirements.txt, the requirement of "docutils<0.17" can be met naturally.

| | | | | | | | | The kernel build system as a whole is dropping support for Python 2, so we should do the same.

* docs: update requirements to install six moduleJaeSang Yoo2020-12-101-0/+1
| | | | | | | | | | | | | | | | | On the update of Sphinx version to 2.4.4, the "six" library won't be installed automatically. (which is required by kfigure.py) Main reason of this issue were occurred by the requirements changed from the sphinx library. In Sphinx v1.7.9, six was listed on the install_requires, but it has been removed since 2.x The kfigure.py uses six library explicitly, adding six to requirements.txt seems reasonable Signed-off-by: JaeSang Yoo <jsyoo5b@gmail.com> Reviewed-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org> Link: https://lore.kernel.org/r/20201208014628.GA1361@JSYoo5B-Base.localdomain Signed-off-by: Jonathan Corbet <corbet@lwn.net>
* docs: update recommended Sphinx version to 2.4.4Mauro Carvalho Chehab2020-04-201-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are some docs that have nested tables. While this was always part of the spec, only Sphinx version 2.4.x can translate it to LaTeX. In other words, if someone is using a Sphinx version < 2.4, the LaTeX and PDF output won't work for some of the docs. So, it seems that it is time to raise the bar again for the recommented version. The Sphinx check script is already smart enough to keep working, with older versions, warning the users that an upgrade is recommended (and explaining how): Sphinx version 1.7.9 Warning: It is recommended at least Sphinx version 2.4.4. Detected OS: Fedora release 31 (Thirty One).
