docs: kernel_include.py: Cope with docutils 0.21

2024-05-25T14:17:18+00:00

commit d43ddd5c91802a46354fa4c4381416ef760676e2 upstream.

Running "make htmldocs" on a newly installed Sphinx 7.3.7 ends up in
a build error:

    Sphinx parallel build error:
    AttributeError: module 'docutils.nodes' has no attribute 'reprunicode'

docutils 0.21 has removed nodes.reprunicode, quote from release note [1]:

  * Removed objects:

    docutils.nodes.reprunicode, docutils.nodes.ensure_str()
        Python 2 compatibility hacks

Sphinx 7.3.0 supports docutils 0.21 [2]:

kernel_include.py, whose origin is misc.py of docutils, uses reprunicode.

Upstream docutils removed the offending line from the corresponding file
(docutils/docutils/parsers/rst/directives/misc.py) in January 2022.
Quoting the changelog [3]:

    Deprecate `nodes.reprunicode` and `nodes.ensure_str()`.

    Drop uses of the deprecated constructs (not required with Python 3).

Do the same for kernel_include.py.

Tested against:
  - Sphinx 2.4.5 (docutils 0.17.1)
  - Sphinx 3.4.3 (docutils 0.17.1)
  - Sphinx 5.3.0 (docutils 0.18.1)
  - Sphinx 6.2.1 (docutils 0.19)
  - Sphinx 7.2.6 (docutils 0.20.1)
  - Sphinx 7.3.7 (docutils 0.21.2)

docs: Fix the docs build with Sphinx 6.0

2023-01-18T10:42:01+00:00

commit 0283189e8f3d0917e2ac399688df85211f48447b upstream.

Sphinx 6.0 removed the execfile_() function, which we use as part of the
configuration process.  They *did* warn us...  Just open-code the
functionality as is done in Sphinx itself.

Tested (using SPHINX_CONF, since this code is only executed with an
alternative config file) on various Sphinx versions from 2.5 through 6.0.

tweewide: Fix most Shebang lines

2021-05-22T09:38:30+00:00

commit c25ce589dca10d64dde139ae093abc258a32869c upstream.

Change every shebang which does not need an argument to use /usr/bin/env.
This is needed as not every distro has everything under /usr/bin,
sometimes not even bash.

Documentation: sphinx: Don't parse socket() as identifier reference

2019-08-12T20:55:30+00:00

With the introduction of Documentation/sphinx/automarkup.py, socket() is
parsed as a reference to the in-kernel definition of socket. Sphinx then
decides that struct socket is a good match, which is usually not
intended, when the syscall is meant instead. This was observed in
Documentation/networking/af_xdp.rst.

Prevent socket() from being misinterpreted by adding it to the Skipfuncs
list in automarkup.py.

Documentation: sphinx: Add missing comma to list of strings

2019-08-12T20:54:22+00:00

In Python, like in C, when a comma is omitted in a list of strings, the
two strings around the missing comma are concatenated.

docs: load_config.py: ensure subdirs end with "/"

2019-07-19T11:49:27+00:00

The logic with seeks for a subdir passed via SPHINXDIRS is
incomplete: if one uses something like:

	make SPHINXDIRS=arm pdfdocs

It will find both "arm" and "arm64" directories. Worse than
that, it will convert "arm64/index" to "4/index".

docs: load_config.py: avoid needing a conf.py just due to LaTeX docs

2019-07-17T09:57:52+00:00

Right now, for every directory that we need to have LaTeX output,
a conf.py file is required.

That causes an extra overhead and it is actually a hack, as
the latex_documents line there are usually a copy of the ones
that are there already at the main conf.py.

So, instead, re-use the global latex_documents var, just
adjusting the path to be relative ones.

docs: automarkup.py: ignore exceptions when seeking for xrefs

2019-07-08T20:35:47+00:00

When using the automarkup extension with:
	make pdfdocs

without passing an specific book, the code will raise an exception:

	  File "/devel/v4l/docs/Documentation/sphinx/automarkup.py", line 86, in auto_markup
	    node.parent.replace(node, markup_funcs(name, app, node))
	  File "/devel/v4l/docs/Documentation/sphinx/automarkup.py", line 59, in markup_funcs
	    'function', target, pxref, lit_text)
	  File "/devel/v4l/docs/sphinx_2.0/lib/python3.7/site-packages/sphinx/domains/c.py", line 308, in resolve_xref
	    contnode, target)
	  File "/devel/v4l/docs/sphinx_2.0/lib/python3.7/site-packages/sphinx/util/nodes.py", line 450, in make_refnode
	    '#' + targetid)
	  File "/devel/v4l/docs/sphinx_2.0/lib/python3.7/site-packages/sphinx/builders/latex/__init__.py", line 159, in get_relative_uri
	    return self.get_target_uri(to, typ)
	  File "/devel/v4l/docs/sphinx_2.0/lib/python3.7/site-packages/sphinx/builders/latex/__init__.py", line 152, in get_target_uri
	    raise NoUri
	sphinx.environment.NoUri

This happens because not all references will belong to a single
PDF/LaTeX document.

Better to just ignore those than breaking Sphinx build.

Docs: An initial automarkup extension for sphinx

2019-06-26T17:14:09+00:00

Rather than fill our text files with :c:func:`function()` syntax, just do
the markup via a hook into the sphinx build process.

docs: requirements.txt: recommend Sphinx 1.7.9

2019-05-30T16:42:05+00:00

As discussed at the linux-doc ML, while we'll still support
version 1.3, it is time to recommend a more modern version.

So, let's switch the minimal requirements to Sphinx 1.7.9,
as it has the "-jauto" flag, with makes a lot faster when
building documentation.
