[Thierry Dumont]

On my ubuntu 20-04, migrating from beta6 to beta7:

-> compilation: no problem.
-> make ptestlong : all test passed !

Just this:

File "src/sage/tests/parigp.py", line 11, in sage.tests.parigp
Warning, slow doctest:
pari('K = bnfinit(y^4-52*y^2+26,1); pol =
rnfkummer(bnrinit(K,3,1),Mat(5)); L = rnfinit(K, pol);
polredabs(polredbest(L.polabs))') # long time
Test ran for 1100.94 s

(if this indivudual test really took 1100.94 s, it is really long for a
test !).

Yours
t.d.

Is this reproducible, and not just a flaky pexpect thing?

[Eric Gourgoulhon]

Upgrading from Sage 9.2.beta6, the Jupyter notebook is broken: opening a notebook results in a blank page, with the following error message in the console:

[W 12:43:20.344 NotebookApp] 404 GET /nbextensions/mathjax/MathJax.js?config=TeX-AMS-MML_HTMLorMML-full,Safe&delayStartupUntil=configured (127.0.0.1) 11.99ms referer=http://localhost:8888/notebooks/SM_Kerr.ipynb

This is certainly https://trac.sagemath.org/ticket/30123, but this time the "sage -b" trick mentioned in https://groups.google.com/d/msg/sage-devel/mWTD0_iBwKc/qZkOCqhgBgAJ did not work.

Eric.

[Emmanuel Charpentier]

ISTR that make build may unhose you, even if sage -b is (temporarily ?) broken.

Thanks for your suggestion. Unfortunately, "make build" did not help (same error message).

Eric.

A workaround is proposed in https://trac.sagemath.org/ticket/30123#comment:8

I could compile on Mac OS.10.15.6 without installing gcc@9.

Make ptestlong gives me an error 

[Samuel Lelièvre]

The failures all have to do with the locale.
Do we have a meta-ticket for locale-related problems?

[Emmanuel Charpentier]

On Debian testing running on core i7 + 16 GB RAM, upgrading from 9.2.beta5 + Trac#29441, configured to use as much system packages as possible, gives one (transient) timeout and three (permanent) failures, all already reported in previous betas :

----------------------------------------------------------------------
sage -t --long --random-seed=0 src/sage/tests/parigp.py  # Timed out
sage -t --long --random-seed=0 src/sage/rings/complex_arb.pyx  # 6 doctests failed
sage -t --long --random-seed=0 src/sage/tests/gap_packages.py  # 1 doctest failed
sage -t --long --random-seed=0 src/sage/rings/real_arb.pyx  # 2 doctests failed
----------------------------------------------------------------------

HTH,

[Emmanuel Charpentier]

Of note : I lost the ability to launch the Jupyter notebook, as reported in Trac#30123 ; the make build workaround doesn’t work around this bug anymore.

Indeed. But as mentioned in https://trac.sagemath.org/ticket/30123#comment:8, if you restore the broken symlinks in SAGE_ROOT/local/share/jupyter/nbextensions, the Jupyter notebook works again.

Eric.

[Thierry Dumont]

I ran the test again:

sage-t --long ./parigp.py

and this gives:

Warning, slow doctest:
pari('K = bnfinit(y^4-52*y^2+26,1); pol =
rnfkummer(bnrinit(K,3,1),Mat(5)); L = rnfinit(K, pol);
polredabs(polredbest(L.polabs))') # long time

Test ran for 500.40 s
[13 tests, 500.83 s]

Yours,

just running this in straight GP (version 2.11.2)

K = bnfinit(y^4-52*y^2+26,1);
pol = rnfkummer(bnrinit(K,3,1),Mat(5));
L = rnfinit(K, pol);
polredabs(polredbest(L.polabs))

finishes in few seconds. (but very slow in 2.11.4)

A regression in PARI/GP, not a Sage's problem, really.

Built from fresh clones of the 9.2.b7 branch, on three macOS systems: 10.13.6 (2019 iMac Pro, 18-core Xeon W); 10.14.6 (2017 MBP, Quad-core Core i7); and 10.15.6 (2019 MBP, 8-core Core i9).

No problems with the builds, and testing (‘ptestlong’) on each completed with no failures.

On my Raspberry Pi 4 8GB build fails on cvxopt

* package:         cvxopt-1.2.3

  last build time: Aug 17 14:34

  log file:        /home/pi/sagemath/sage-9.2.beta7/logs/pkgs/cvxopt-1.2.3.log

  build directory: /home/pi/sagemath/sage-9.2.beta7/local/var/tmp/sage/build/cvxopt-1.2.3

[Matthias Köppe]

cvxopt build is also known to fail on i386 (https://trac.sagemath.org/ticket/30052)

[Dima Pasechnik]

I've tracked it down to some weirdness in cvxopt's setup.py and opened
https://github.com/cvxopt/cvxopt/issues/174

cvxopt's setup tries to figure out exact paths to system libraries by
going through a fixed list,
which does not include the corresponding locations for ARM CPUs on
Debian/Raspberry Pi
These locations need not be set at all, as the linker knows them.

We already override many of these paths in our spkg-install script via environment variables
