[Sébastien Labbé]

On Ubuntu 16.04, the command

sage -t --all --optional=sage,optional,external

tests the following optional and external doctests:

Using --optional=bliss,cbc,ccache,cmake,dot2tex,external,gmpy2,lrslib,memlimit,mpir,normaliz,notedown,pandoc_attributes,pycosat,pynormaliz,python2,rst2ipynb,sage

External software detected for doctesting: ffmpeg,graphviz,gurobi,imagemagick,internet,latex,pandoc

and gives All tests passed except the following ones:

The findstat doctest is a trivial fix (remove the first useless ellipsis), if you open a ticket, I'll fix it immediately.

Thank you for noticing!

On Ubuntu 18.04 running on Xeon E5-2623 + 16 GB RAM:

- python2:

  - incremental build (-j16) from 8.5.beta3 OK

  - all tests from ptestlong passed

 

- python3:

  - incremental build (-j16) from 8.5.beta3 OK

  - threejs viewer, tested with "sphere(viewer='threejs')", works from the console, but not in a Jupyter notebook: the following error occurs in line 572 of src/sage/repl/rich_output/

backend_ipython.py;

TypeError: a bytes-like object is required, not 'str'

I might have missed it, but have you ever mentioned if there is a
target release date and/or cutoff date for non-critical issues for
this version?

Thanks! Sounds good. Sounds like we probably won't have GAP 4.10 in
time for that then, most likely... :(

Perhaps we can make a 8.6 relatively quicker after... I'll do what I
can in the meantime, but I have my doubts.
