Deprecations

sphinx-hoverxref uses some interfaces removed in sphinx 9.0. However, sphinx-hoverxref is it itself deprecated, so we should drop it anyhow.

Depends on

#1341, which limits docs to only being typechecked on the version it runs on.

Are you planning on dropping hoverxref in this or in a separate PR?

Planning to drop hoverxref on another PR.

This one is also blocked by needing to figure out pyright 3.8-3.10 overrides

Looks good overall! A couple things:

• Could we just filter the sphinx 9.0 deprecation warning for the time being, until we replace hoverxref properly?
• Low priority, but this info log is pretty noisy, could potentially filter it
• Similarly, Converting `source_suffix = '.rst'` to `source_suffix = {'.rst': 'restructuredtext'}`. - we could update this in conf.py as well. It's always been doing this conversion, but the log was only added recently
• On subsequent autobuild runs, I'm getting Aborted attempted copy from rendered template _templates/api_redirect.js_t [...]. As far as I can tell, we now need a force=True here: https://github.com/DisnakeDev/disnake/blob/e93670d6480018a8344fd555ffdcb71019e966c3/docs/extensions/redirects.py#L40-L44
  • Somewhat related, since the copy_redirect_script hook here takes Exception instead of Exception | None, type checkers consider most of that function dead code

A couple more things I noticed:

• Sphinx added the classic purple coloring to visited links, the contrast with the documentation's background color is awful (contrast ratio of 1.05): I think the best solution would be to override that selector and remove the highlight, visited link tracking for a documentation website seems fairly pointless to me anyway.
• Maybe it's just the PR preview build, but search is pretty broken outside of the indexed results; it requests pages like https://disnake--1325.org.readthedocs.build/en/1325/undefinedext/tasks/index.html, which obviously don't resolve. ~~Haven't really investigated why, yet.~~
  • edit: data-content_root is missing on the root element, see https://github.com/sphinx-doc/sphinx/issues/11608#issuecomment-1684410476
• Redirects from the old api.html#ref to api/page.html#ref are broken, since URL_ROOT no longer exists (see previous point). We should use document.documentElement.dataset.content_root instead.

(also, thanks for including links to all the changelogs <3)
