reporting on Sage.9.0.beta4

[Sébastien Labbé]

I am reporting on the following release from 3 days ago (I am creating a new thread since it has not been created yet).

┌────────────────────────────────────────────────────────────────────┐
│ SageMath version 9.0.beta4, Release Date: 2019-11-02               │
│ Using Python 2.7.15. Type "help()" for help.                       │
└────────────────────────────────────────────────────────────────────┘

Running tests with optional + external packages, I get:

Using --optional=awali,cbc,ccache,cryptominisat,dot2tex,e_antic,external,glucose,memlimit,normaliz,notedown,openssl,pandoc_attributes,pycosat,pynormaliz,python2,rst2ipynb,sage

----------------------------------------------------------------------

sage -t --long src/sage/databases/findstat.py  # 52 doctests failed
sage -t --long src/sage/symbolic/integration/external.py  # 1 doctest failed
sage -t --long src/sage/geometry/polyhedron/base_QQ.py  # 3 doctests failed
----------------------------------------------------------------------
External software detected for doctesting: ffmpeg,graphviz,imagemagick,internet,latex,pandoc

Rerunning failed tests, I get:

----------------------------------------------------------------------

sage -t --long src/sage/geometry/polyhedron/base_QQ.py  # 3 doctests failed
sage -t --long src/sage/databases/findstat.py  # 62 doctests failed
----------------------------------------------------------------------
External software detected for doctesting: internet

The transient error is:

sage -t --long src/sage/symbolic/integration/external.py

Got:

It seems the following 3 tests are missing the latte optional tag:

The base_QQ.py errors are likely to be linked to

https://trac.sagemath.org/ticket/18957

It should be easily fixed, I created ticket:

https://trac.sagemath.org/ticket/28700

for that.
