Sage 10.4.beta7 released

[Volker Braun]

As always, you can get the latest beta version from the "develop" git branch. Alternatively, the self-contained source tarball is at http://www.sagemath.org/download-latest.html

[Enrique Artal]

In Fedora 40 I encountered one error building the documentation, because it did not find libflint.so.18 (it is now libflint.so.19). I got two solutions: symbolic link of libflint.so.19 to libflint.so.19, or complete rebuild.

The test passed for src/sage/libs/gap/element.pyx and had the following errors:

----------------------------------------------------------------------

----------------------------------------------------------------------

The error for cmdline.py is old and related to sage_sws2rst.

For tests.py:

**********************************************************************
File "src/sage/calculus/tests.py", line 126, in sage.calculus.tests
Failed example:
   integrate(x^x,x)
Expected:
   integrate(x^x, x)
Got:

; _Alloc = std::allocator<long long int>; reference = long long int&; size_type = long unsigned int]: Assertion '__n < this->size()' failed.
   integrate(x^x, x)
**********************************************************************

For real_mpfr.pyx is a fricas failure. For giac.py, maybe it comes from the system package as for maxima_abstract.py

This one seems cosmetic (a deprecation warning not accoulted for in the expected response, which is correct).

Note the huge difference in timing.

I regularly  follow beta releases (as in https://github.com/void-linux/void-packages/pull/49571) and I don't remember seeing so many regressions in a single prerelease in the past. What is going on with CI?

Best,

Gonzalo

[Gonzalo Tornaría]

Apologies. I was despaired by the number of failures, but mostly everything is fixed by https://github.com/sagemath/sage/pull/38081, except for:

- The segfault in sage/matrix/matrix_integer_dense.pyx has been happening for a while. It seems to be happening more often now (but that may be perception only). I still haven't found a deterministic way to reproduce it.

- The timeout in sage/stats/distributions/discrete_gaussian_lattice.py is a real thing that happens randomly, it's just that in 10.4.beta7 it happens much more often (always?) and #38081 brings it back to the fail randomly state.

As for the last one: see https://github.com/sagemath/sage/pull/36581#issuecomment-2071297439.

It seems to me the code in the PR is incorrect, but the doctest is wrong and it's being fooled with very high probability. Very occasionally, the test works and it timeouts (because the code is incorrect). I hope this can either be fixed before 10.4 or reverted, because giving wrong answers is IMHO worse than not having a feature.

Best,

Gonzalo
