Thanks, fixed.

[Eric Gourgoulhon]

From a fresh git clone + pull develop on Ubuntu 16.04 x86_64 i7-6700HQ + 16 MB RAM, parallel (-j8) build OK and make ptestlong successful.

Eric.

Fresh clone on Linux Mint 17.3, make ptestlong brings up:

Due to the still not fixed https://trac.sagemath.org/ticket/20270:

sage -t --long src/sage/interfaces/expect.py # 1 doctest failed
sage -t --long src/sage/repl/interpreter.py # 3 doctests failed
sage -t --long src/sage/repl/interface_magic.py # 3 doctests failed
sage -t --long src/sage/repl/ipython_tests.py # 4 doctests failed

Some time out (why do we get these so often???):

sage -t --long src/sage/modular/abvar/torsion_subgroup.py # Timed out

Full timeoutlog below.

Built from a clone/checkout of the develop branch, on macOS 10.11.6 (Quad-core Core i7), without problems (-j6). Testing (‘ptestlong’) yielded two timeouts:

----------------------------------------------------------------------
sage -t --long --warn-long 80.6 src/sage/geometry/cone.py # Timed out
sage -t --long --warn-long 80.6 src/sage/modular/modsym/space.py # Timed out
----------------------------------------------------------------------

I reran the full “make” (no rebuilding), and got another two timeouts.

----------------------------------------------------------------------
sage -t --long --warn-long 79.1 src/sage/graphs/matchpoly.pyx # Timed out
sage -t --long --warn-long 79.1 src/sage/doctest/external.py # Timed out
———————————————————————————————————

Logs available for each run, if interested.

[Volker Braun]

This is sed on OSX crapping out since you have a locale that doesn't mesh with ru. Does 

LC_ALL=C make doc-pdf

work? 

[John H Palmieri]

Yes, that seems to take care of that problem, although now I'm having other problems with the PDF docs. If I figure it out and if it's not something I did, I'll post here again.
