Describe the bug

In the pytest-checkdocs project, I'm running tox -e docs and the run fails with this output:

The issue is new to Sphinx 4.2. If I run the tests on Python 3.9 and Sphinx 4.1.2, the docs build, though with a warning:

/Users/jaraco/code/main/pytest-checkdocs/pytest_checkdocs/__init__.py:docstring of pytest_checkdocs.CheckdocsItem:1: WARNING: py:class reference target not found: _pytest.nodes.Item

That warning is just a nitpick.

Docs are building on other projects, so there must be something unique about this project that's triggering the failure.

How to Reproduce

$ git clone https://github.com/jaraco/pytest-checkdocs
$ cd pytest-checkdocs
$ git checkout b4153a403388c4944c5a4f883b68bfa5531b1617
$ tox -e docs

Expected behavior

Docs should build or provide an actionable error message.

That's strange. How did you install docutils-0.18? Sphinx-4.2.0 depends docutils < 0.18. So it seems your environment is inconsistent. Please downgrade docutils to 0.17.1.

I installed everything using tox. Tox is using pip to install .[docs,testing].

When I create my own virtualenv and install .[docs,testing], it works fine.

WARNING: You are using pip version 21.2.4; however, version 21.3.1 is available.
You should consider upgrading via the '/Users/jaraco/code/main/pytest-checkdocs/.tox/docs/bin/python -m pip install --upgrade pip' command.

Aha, so the clue is in the message:

ERROR: pip's legacy dependency resolver does not consider dependency conflicts when selecting packages. This behaviour is the source of the following dependency conflicts.
sphinx 4.2.0 requires docutils<0.18,>=0.14, but you'll have docutils 0.18 which is incompatible.

So pip is telling me it knows it's installed incompatible versions and it can't do anything about it. But why does it do that only when invoked by tox?

Strangely, even when I run those same commands on my own, I'm unable to replicate the behavior that I see when running under tox.

My best guess at this point is virtualenv is passing parameters to pip in secret (such as through environment variables) that are somehow triggering the use of the legacy resolver.

Perhaps the fact that the project under test (pytest-checkdocs) depends on docutils is a factor.

In any case, thanks for pointing to the cause and helping me discover the issue. I'll follow up with the tox project to figure out why the legacy resolver is being used.

confirm - update lib to sphinx==4.3.0 version - it will fix your issue

While working on another PR I ran into this bug on my test website. I had a test document with only an HTML code block and found out unescaped HTML was added to the meta tag: ```html <meta property="og:description" content="<meta property="og:image" content="_images/normal.jpg" /> <img alt="_images/normal.jpg" src="_images/normal.jpg" />" /> <meta property="og:image" content="_images/normal.jpg" /> ``` Fixing this by skipping literal blocks. Also fixed docs build. I was getting the exception: `AttributeError: 'Values' object has no attribute 'section_self_link'` This was caused by sphinx-doc/sphinx#9825. Updating dependencies fixed the issue.
