Sage 9.5 released

[Volker Braun]

The "master" git branch has been updated to Sage-9.5. 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

On Ubuntu 21-10:
-upgrading from 9.4

compilation ok in both cases.

Thanks, Volker, for the new release!

I have prepared the 9.5 changelog at https://github.com/sagemath/website/pull/232/files

 

 

[François Bissey]

Can we have a sage-9.5 tarball on GitHub soon? It is the only place I can find the “src/doc” folder needed to build the documentation in sage-on-gentoo currently.

You can find it on the mirrors
https://www.sagemath.org/download-source.html e.g.
http://www-ftp.lip6.fr/pub/math/sagemath/src/sage-9.5.tar.gz

Ciao,

That page is still listing 9.4 and not all mirrors have 9.5 yet. aarnet which would be my closest mirror is not yet updated at the time of writing.
I guess I’ll wait a few hours.

[Emmanuel Charpentier]

FWIW, rebuilding (make distclean & configure <...> && make) 9.5 and running ptestlong on Debian testing running on core i7 + 16 GB RAM gets me two permanent failures already reported on previous versions :

sage -t --long --warn-long 261.6 --random-seed=336852289013645786488965399190997684269 src/sage/algebras/quantum_groups/quantum_group_gap.py  # 1 doctest failed
sage -t --long --warn-long 261.6 --random-seed=336852289013645786488965399190997684269 src/sage/functions/min_max.py  # 2 doctests failed

In other words, rebuilding Sage solved my recently reported giac problem ; running system’s giac 1.7.0 solves the integration problem recently reported wit Sages giac 1.6.0 version.

On the other hand, my problem with eigenvalues of algebraic matrices remains unsolved.

HTH,

[François Bissey]

I just remember while downloading one of these tarballs why I prefer the GitHub one. It is much smaller since it doesn’t have the “upstream” folder which is otherwise irrelevant to my packaging. Downloading one of these for my purpose is a waste of bandwidth for me and the users.

[Kenji Iohara]

On my Mac OS 12.1 with intel core i5 , it compiled from the first built. 

But  ``make ptest’’ failed; here is the log file.

Thank you Volker and all the authors and reviewers for the release of 9.5!

[Eric Gourgoulhon]

Thank you Volker for the release!

On Ubuntu 20.04 running on Xeon E5-2623 + 16 GB RAM:

- parallel build (-j16) from a fresh git clone, with system python (3.8.10): OK

- make ptestlong: passed, except for 2 doctests in src/sage/game_theory/parser.py

This failure is the lrslib issue dealt with in https://trac.sagemath.org/ticket/33101

Eric.

[John Cremona]

I just successfully built 9.5 from a fresh tarball. After completing
the build I installed (as I usually do) an optional package with the
command-line "./sage -i database_cremona_ellcurve" and now it is
rebuilding gmp. What is going on here? Has the way of installing
optional packages changed -- in which case, surely the use of "sage
-i" should tell you what to do instead, instead of doing the 'wrong'
thing?

On a different machine (core i5, 8 GB RAM, Debian testing), upgrading 0.5.beta9 to 9.5 and running ptestlong gave me one transient failure :

Sage uses system’s giac, which is 1.7.0.

These results (and those observed on the other machine) seem to point to some unrecorded dependencies of the giac interface. They also point to some deficiency in giac’s handling of large integers and in signal management in Cythonized code…

Thanks Volker for this new release!

On Debian 10 buster, `make -s V=0 ptestlong` fails on two files:
```
... src/sage/features/interfaces.py # Timed out
... src/sage/game_theory/parser.py # 2 doctests failed
```

Ticket #33101 takes care of `src/sage/game_theory/parser.py`.
Ticket #33248 takes care of `src/sage/features/interfaces.py`.

After applying these two tickets on top of Sage 9.5, "All tests passed!".

Ticket #33101 has been closed, which likely means it will be part
of Sage 9.6.beta0. Please consider including #33248 too. That way
my "pascaline" patchbot can be restarted. --Samuel

In Cygwin in Windows 10, the build fails for me
on `sagemath_doc_html`, as has been the case
on that machine since Sage 9.5.beta7.
