[kiwifb]

I have seen that before but have no fix apart from downgrading your mpmath to a lower version.

[yamabiiko]

I confirm that after downgrading mpmath from 1.4.0_alpha1 to 1.3.0-r1 the build is successful

[kiwifb]

Of course, it will have to be fixed properly. But the new mpmath is alpha1 which means there could be many changes before the final release, making it a potentially fast moving target.

[narodnik]

I tried to downgrade but I get this issue:

sphinx 8 just got to stable and I have not checked it yet. But I am expecting it is the one giving you troubles. Most major bump in sphinx resulted in that kind of troubles.

[kiwifb]

Not stable actually but 8.0.0_rc1 is in the tree in unstable.

[kiwifb]

Testing a fix for sphinx8. Looks kind of ridiculous.

[kiwifb]

Plot twist. After I remove the offending import and the related code, there is another failure with sphinx-8.0.0_rc1. There are complaints that inspect.isNewType cannot be found in sphinx.util. And yes it appears to be present in 7.4.7 and gone in 8.0.0_rc1. The problem is that I cannot see it on https://www.sphinx-doc.org/en/master/extdev/deprecated.html - so officially it should still be there.

[kiwifb]

Complaining at sphinx-doc/sphinx#12646

[kiwifb]

The old clone of ext/autodoc.py strikes again. This is an internal API so it should not have been used, and adapting to it will strictly tie us up to sphinx 8.0.0. which is OK.

[narodnik]

Ah great, lmk once it's patched. We're awaiting your orders ;)

[kiwifb]

Don't expect quick service on that one. It is more complicated than I want. If you want the doc quick, just mask >=dev-python/sphinx-8.0.0_rc1.

[narodnik]

fyi this worked! Thanks!

[kiwifb]

I have stuff brewing slowly, should I backport support for mpmath 1.4 and sphinx 8 into sage 10.4? I will probably draw the line at python 3.13 unless it turns out easy..

[kiwifb]

OK, I am going to merge stuff that's been included upstream shortly. Support for sphinx 8 is included same story than #794 about patching.
mpmath is not coming yet, I am discussing support with upstream (mpmath that is not sagemath) a number of fixes are needed but not merged yet in mpmath. And there is one outstanding problem.

[strogdon]

This is the latest sage-doc-9999 for sagemath-10.5.beta3. I have sphinx-8.0.2 installed as well as mpmath-1.3.0-r1. So I get:

I'm not sure where these imports are

[reference] Warning: Sage imports in libelefun failed
[reference] Warning: Sage imports in libmpc failed

[kiwifb]

I am going to guess some python libraries need rebuild after the upgrade to numpy 2. I would rebuild gmpy and fpylll and see if that helps.

[kiwifb]

Both libelefun and libmpc are from mpmath. But I cannot find a call to libmpc inside sage.

[kiwifb]

Some of the mpmath stuff may be too much. I may have to back-pedale until mpmath-1.4 gets into shape.

[kiwifb]

OK pushed to master, you'll need to rebuild sagemath-standard-9999 as I removed the patch from PR38113 which causes problems (but should not).

[strogdon]

sage-doc-9999 now builds as of commit 3e185c1
