mpir removal was not complete, as a result ./bootstrap etc may complain. Fix is here:

I got two doctest failures on a freshly compiled sage on Debian
bullseye (see below). The first one looks similar to
https://trac.sagemath.org/ticket/27477. The second one is
plausibly dependent on the version of gmp used.

Best
Vincent

I actually observed the second one in sage-on-gentoo but it didn’t persist after re-running twice the doctest.
I still have the failure in my logs but cannot reproduce it anymore.

On my mac OS 11.6, the first compilation worked and ``make ptestlong’’ passed.

Starting with this release, doctests will be run with a random seed chosen at random. This can be reproduced as indicated by the output

sage -t --random-seed=1234

Most of the doctests should be ready for this. I opened

https://trac.sagemath.org/ticket/32544

to collect further failures due to fuzzing the doctests. Also it now makes sense to test your algorithm on random instances (previously this would test exactly one object).

is there a way to control the seed via, say, an env. variable?

Dear Jonathan,

Thanks for pushing this forward. Just one thing: in case of test
failure, is the random seed available in the log to be able to
reproduce that failure?

Best regards,
Nicolas

Hi Nicolas,
since a while, you see the random seed prominently shown in the output:

sage -t --random-seed=0 src/sage/calculus/transforms/dwt.pxd

In particular, the failure with projective_ds.py does not reproduce, but is new so I copy it below. Also graph.py has 3 doctests failed and 2 doctests failed on the second run. So I copy both of them below. However, the three failing tests are not new.

A new failure is with dimacs.py related to the glucose SAT solver, which I copy below.

Other failures were already reported. Follow up at : https://trac.sagemath.org/ticket/25536

Thanks for this new development release!

On Cygwin, failed to build SciPy.
I might try #32746 which fixes a similar problem on Fedora.

I have updated my Mac OS to Monterey 12.0.1 and it compiled from the first build.

That worked.

On Cygwin 3.2.0 in Windows 10 on an ACER laptop,
for SageMath 9.5.beta4 + ticket #32746, the command
`make -s V=0 ptestlong` succeeds: "All tests passed!"

Looking forward to Sage 9.5.beta6, hopefully with that
ticket merged in, since it didn't make it into beta5.

On other platforms, for Sage 9.5.beta4 (no extra ticket):

- Debian 10 buster with many apt packages,
`make -s V=0 ptestlong` gives "All tests passed!".

- macOS 10.14.6 Mojave with Homebrew packages,
`make -s V=0 ptestlong` gives "All tests passed!".

On to test 9.5.beta5. Cheers, --Samuel
