For what it's worth, I found it by going to the module documentation on an earlier version and using the dropdown to navigate to 3.10. If you go to the dataclasses docs and select a version where it doesn't exist yet (e.g., 3.6), it redirects to https://docs.python.org/3.6/. That feels like the right behavior here too. ---------- _______________________________________ Python tracker <report@bugs.python.org> <https://bugs.python.org/issue44006> _______________________________________

Julien Palard <julien+python@palard.fr> added the comment: This is interesting! Also notice the footer: Last updated on Jul 26, 2020. I checked on the docsbuild server and found the `symbol.html` file was marked as modified today (probably by the build cron) (and it contains the "Last updated on Jul 26, 2020" string, yes). I think the explanation may be that Sphinx does not remove a file from the html output when it's rst counterpart is removed (which may be legitimate, Sphinx can't guess the rst was there before, so it can't distinguish if it's a human generated file that should be kept, or an old file to delete). There's however no links pointing to it (apart when switching version from 3.9 to 3.10 using the version switcher). I'm removing the files manually as is: docsbuild@docs:/srv/docsbuild/3.10$ rm cpython-*/Doc/build/html/library/symbol.html I'll let the daily cron update docs.python.org (to ensure it does the job). ---------- _______________________________________ Python tracker <report@bugs.python.org> <https://bugs.python.org/issue44006> _______________________________________

Jelle Zijlstra <jelle.zijlstra@gmail.com> added the comment: Thanks Julien! I noticed two other libraries in the same situation: https://docs.python.org/3.10/library/formatter.html and https://docs.python.org/3.10/library/parser.html. The RST files for both are also gone from master. Could you purge the cache for them too, or would you prefer I open a new issue? ---------- _______________________________________ Python tracker <report@bugs.python.org> <https://bugs.python.org/issue44006> _______________________________________
