Thanks, Volker, for the new release.

Tests are running at https://github.com/sagemath/sage/actions, first results:

Debian/Ubuntu systems – mostly clean, with the following exceptions:

ubuntu-trusty-minimal (https://github.com/sagemath/sage/runs/1450539640)

sage -t --random-seed=0 src/sage/graphs/connectivity.pyx  # 2 doctests failed

sage -t --random-seed=0 src/sage/doctest/test.py  # Timed out

sage -t --random-seed=0 src/sage/rings/polynomial/plural.pyx  # 2 doctests failed

The first one is new, I think. File "src/sage/graphs/connectivity.pyx", line 2686, in sage.graphs.connectivity._Component.__init__

Failed example:

         for(mp_bitcnt_t i = 0; i < limbs; i++){

The last one, plural.pyx, is likely the same as https://trac.sagemath.org/ticket/29528

Likewise on ubuntu-trusty-standard, debian-jessie-minimal, debian-jessie-standard

Homebrew:

https://trac.sagemath.org/ticket/30929 needs review so that Big Sur and more Xcode variations are tested in the next beta.

I opened https://trac.sagemath.org/ticket/30958 for the C99 thing that caused the following:

Hints ?

[Sébastien Labbé]

On Ubuntu 18.04, running tests with various optional and external packages, I get:

Using --optional=4ti2,cbc,ccache,cryptominisat,database_jones_numfield,debian,dot2tex,e_antic,external,fricas,glucose,latte_int,libnauty,lidia,lrslib,memlimit,normaliz,notedown,pandoc_attributes,pip,pycosat,pynormaliz,rst2ipynb,sage,sage_numerical_backends_coin,sage_spkg

sage -t --long --warn-long 56.3 --random-seed=0 src/sage/interfaces/singular.py  # Killed due to segmentation fault
----------------------------------------------------------------------
External software detected for doctesting: ffmpeg,graphviz,imagemagick,internet,latex,octave,pandoc

I can reproduce it when running the command:

sage -t --long --warn-long 73.3 --random-seed=0 src/sage/interfaces/singular.py

[Dima Pasechnik]

Looks like your ./configure is stale.
build/bin/sage-system-python is gone now, and you need to run

./bootstrap

first

I confirm the seg fault on Ubuntu 20.04 (Sage 9.3.beta2 built with the system Python = 3.8.5, but with Sage's singular = 4.1.1p2).

On the same computer (Intel Core i7-8665U + 32 GB RAM), the issue is already there with Sage 9.2, but not with Sage 9.1.

Yes, exactly.

I have updated to Mac OS 11.0.1 and the compilation from the first built done without problem !

However, for make ptestlong, there are several errors:

[Dima Pasechnik]

A number of tests in your case fail due to a Japanese locale problem, e.g.

Failed example:
sage.misc.sageinspect.sage_getargspec(r.lm)
Expected:
ArgSpec(args=['self'], varargs='args', keywords='kwds', defaults=None)
Got:
起動準備中です - 警告メッセージ:
1: Setting LC_COLLATE failed, using "C"
2: Setting LC_TIME failed, using "C"
3: Setting LC_MESSAGES failed, using "C"
4: Setting LC_MONETARY failed, using "C"
ArgSpec(args=['self'], varargs='args', keywords='kwds', defaults=None)

I am not sure what's going on there. It looks like these are coming from
a non-Sage python module, such as re.
What is the output of

sage: import locale
sage: locale.setlocale(locale.LC_ALL, '')

on your system?

oops, sorry, there is " there, but it should be two ' characters one after another.

Dima is suggesting the command locale.setlocale(locale.LC_ALL,''), where just before the parenthesis should be two single quotes. No quotes after the parenthesis. Or if you prefer: locale.setlocale(locale.LC_ALL,"") with two double quotes just before the parenthesis.

the 2nd line should be

locale.setlocale(locale.LC_ALL,'')

(I don't know why you ended up with " instead of '' in the first
place, probably your keyboard has a setting that automatically
converts '' into ")

HTML email is evil, too - I think it's clearly visible in
my original message that it was '', if viewed with a normal
terminal font :-)

OK, thanks.  It gives me

sage: import locale                                                             

sage: locale.setlocale(locale.LC_ALL,'')                                        

'C/UTF-8/C/C/C/C’

Does this tell you something ?

this does not look like a valid locale description.
E.g. for me the output is

'en_GB.utf8'

What is the output of locale command in the terminal you start Sage from?
E.g. for me it is

dima@hilbert ~ $ locale
LANG=en_GB.utf8
LC_CTYPE="en_GB.utf8"
LC_NUMERIC="en_GB.utf8"
LC_TIME="en_GB.utf8"
LC_COLLATE="en_GB.utf8"
LC_MONETARY="en_GB.utf8"
LC_MESSAGES="en_GB.utf8"
LC_PAPER="en_GB.utf8"
LC_NAME="en_GB.utf8"
LC_ADDRESS="en_GB.utf8"
LC_TELEPHONE="en_GB.utf8"
LC_MEASUREMENT="en_GB.utf8"
LC_IDENTIFICATION="en_GB.utf8"
LC_ALL=

(this is on Linux, on macOS it looks very similar)

Too late for this time, but next time this information is needed,
one could ask to run this command (no trouble with quotes!):
```
sage: import locale
sage: locale.setlocale(locale.LC_ALL, str())
```

[Dima Pasechnik]

I've managed to (sort of) reproduce this issue, by doing

export LANG=""
locale
export LANG="en_GB.utf8"

in the shell, then I see

% locale
LANG="en_GB.utf8"
LC_COLLATE="C"
LC_CTYPE="C"

LC_MESSAGES="C"
LC_MONETARY="C"
LC_NUMERIC="C"
LC_TIME="C"
LC_ALL=

And same error in plain Python3, and in /usr/bin/python (Python 2 from macOS)

This is all on macOS 10.15.7 with Homebrew.

To wit: terminal locale is fragile and weird. If it's broken then
Python has issues with it.
If your terminal locale is broken, fixing it is a good idea, but we
don't really know how.
Internet searches suggest to fiddle with "Set locale environment
variables on startup"
settings in the Terminal app (in Terminal, open
Preferences->Profiles->Advanced, look at "International" there)

Surely in Japan Python users on macOS must have figured out what to do.
