Do we plan to distribute also a python3-version of sage 8.8 (binaries) ? Of course, some tests are still not passing, but sage works nevertheless.

IMHO it is too early.
Some parts of python3 version produce patently incorrect results, e.g.
graph automorphisms/isomorphisms.
It would not be a good idea to distribute such a binary without big
warnings printed to that effect.

Then how about distributing it with big warnings.

There is Python 3 impatience in part of Sage's user base.
Distributing an experimental Python 3 version would send
a good signal.

We could call the binaries "SageMath-py3-experimental"
and include a big warning in the banner, with a link to the

"Migration to Python 3" page on the Sage wiki.

Having a binary distribution with py3 would also be very valuable also for user packages that run automated tests on CI systems, such as those based on https://github.com/sagemath/sage_sample

Built from fresh clone of the develop tree, with no problems, on three macOS platforms. Testing (‘ptestlong’) went as follows:

10.11.6 (mid-2015 MBP, Quad-core Core i7): one transient failure (succeeded when run singly):
File "src/sage/matrix/matrix_space.py", line 1981, in sage.matrix.matrix_space.MatrixSpace._an_element_
Failed example:
M.density()
Expected:
99/1000000
Got:
49/500000

10.13.6 (2017 iMac Pro, 18 core Xeon W): all tests passed!

10.14.5 (2017 MBP, Quad-core Core i7): one transient failure (succeeded when run singly):
sage -t --long --warn-long 76.2 src/sage/parallel/map_reduce.py
Timed out

Justin

PS: timeouts on the MBP’s may be due to their habit of sleeping if ignored for too long. I have yet to figure out why, and persuade them to knock it off. (I have them on power when testing, and settings off that induce sleeping [AFAICT]).

Have you unchecked the "Put hard disks to sleep when possible"
checkbox in the "Energy Saver" settings of "System Preferences"?

Thanks for the reply.

Yes, I do have that unchecked. There are two checked items for “Power Adapter":
- Prevent computer from sleeping…
- Wake for wi-fi access

After fixing the pynormaliz issue myself, I may run optional and external doctests, and I get:

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

sage -t --long src/sage/combinat/designs/ext_rep.py # 1 doctest failed
sage -t --long src/sage/databases/findstat.py # 8 doctests failed
