[John H Palmieri]

Broken with a Python 2 build. Do we care?

In particular, SageNB is not built with Python 2, but the doctester thinks it should be:

./sage -t -p --all --long --logfile=logs/ptestlong.log

Here’s another one, just like the other one :-}
Built from a fresh clone of the develop branch on two macOS systems: 10.13.6 (2017 iMac Pro, 18-core Xeon W); and 10.15.6 (2017 MBP, Quad Core i7). No problems with the builds, and all tests (‘ptestlong’) passed!

Yes. sagenb is no a real optional package even with python2. We overlooked
the test suite when we made some test depending on it just “# py2”.
That was in https://trac.sagemath.org/ticket/28805.
We probably really should have introduced `# sagenb` in insight.
But honestly I don’t care that much about python2 anymore.
In 30 days it will be best efforts at best for python2.

[Samuel Lelièvre]

I think we should maintain Python2 compatibility at least for this version.

[Dima Pasechnik]

the easiest might be to build pythonX if --with-python=X is specified.

Can I please get a review on https://trac.sagemath.org/ticket/28258 ?

This issue has been holding me up for weeks, making testing difficult.

Dear Madison,

Does this ticket address a Windows-specific issue, or does testiong it is meaningful under Linux/Mac Os ?

On Debian testing running on Core i5 + 8 GB RAM, (after removal of gap_packages, problematic on this machine, see reports on 9.0.beta7), ptestalllong gets me the usual suspects:10 transient issues (i. e. all tests pass when ran standalone), and no permanent issue :

I guess my real question is: do we automatically build SageNB when `./configure --with-python=2` is used, or do we drop the SageNB doctests? I propose dropping the doctests and at some point creating an spkg-check script for sagenb that runs its tests.

Of note: those results are obtained when this machine is directly connect to the Internet. When stuck behind our corporate-firewall-done-wrong, I get the catastrophic failure reported in this post and diagnosed in further posts.

This, and the fact (reported in the post immediately above this one) that a machine stuck behind this firewall but without gap_packages passes ptestalllong without permanent failures proves, IMHO, that our corporate firewall is incompatible with the needs of gap_packages.

How should I ticket this ?

We do care: Support for Python 2 is not being dropped yet.  Please
open a blocker ticket.

I guess my real question is: do we automatically build SageNB when `./configure --with-python=2` is used, or do we drop the SageNB doctests? I propose dropping the doctests and at some point creating an spkg-check script for sagenb that runs its tests.

I opened https://trac.sagemath.org/ticket/28834

Thanks Volker (who reviewed). With that ticket, plus
https://trac.sagemath.org/ticket/28829 (needed to actually
successfully build) all tests pass on Windows+Cygwin on Python 3.
Testing Python 2 next.

this may be fixed by upgrading gap_packages (specifically, GAP packages Semigroups and Digraphs must be upgraded)

Or we can just wait fot GAP 4.11, where it's fixed by these updates.
