Merges the "Upgrades" section from production/maintain-secure-upgrade.md
with production/modifying-zulip.md.
Contains significant textual changes by tabbott to read more clearly.
We have lots of documentation for Zulip developers; but previously
didn't have a nice top-level page for Zulip server administrators to
learn how to manage patches to Zulip.
- Added warning block to dev docs using _templates/layout.html
- Removed copy-pasted warning from install.md and requirements.md
- Removed unreleased tag in docs/conf.py that's no longer used
Useful ref: https://www.sphinx-doc.org/en/master/templating.htmlFixes#13056.
Now that we have `eval_rst` and can explicitly exclude pages from the
toctree completely, we no longer need to set `includehidden`, and we
can return to using upstream's template.
(Meanwhile, our feature request upstream was successful! See
rtfd/sphinx_rtd_theme#485, which upstream implemented just a week
after we requested it. So that would have been another option.)
This reverts commit 11b8b8f48 "docs: Add rtd layout template."
Sphinx was displaying "WARNING: document isn't included in any toctree"
for files we just don't want in the TOC. We can hide them from the index,
but the rtd theme defaults to display hidden index entries in the nav bar.
This commit excludes these files from such warnings, and patches layout.html
so that hidden index entries stay hidden from the navigation sidebar.
This commit also moves password-strength.md under docs/production and
adds it as a hidden entry in production/index.rst.
Fixes#7417.
The readthedocs theme overrides a few settings in their layout template.
We might want to change some settings back to their default values.
This commit copies the original readthedocs layout file from
https://github.com/rtfd/sphinx_rtd_theme/blob/master/sphinx_rtd_theme/layout.html
to _templates/layout.html, and excludes it from lint and template checks.
Addresses #7417.
