python3 patchbot

Is it possible to set up a patchbot for running tests of SageMath on
Python3?

Yes, I believe so. Frédéric would know the specifics since I think he
made it work. According to the docs you have to put

"tested_files": "py3"

in the patchbot config file (see
https://wiki.sagemath.org/patchbot#Configuration)

But one would also have to ensure that sage is configure with
`--with-python=3` when doing builds, and I'm not exactly sure how best
to force the patchbot to do that. Certainly one way would be to
export the non-obvious environment variable

export PREREQ_OPTIONS="--with-python=3"

as that is passed to `./configure` by the main Makefile.

Ok, thank you. I've set something up which is testing its base right
now. So let's see if this works out :)

What do you expect to do ?

(1) run all the tests and see the 94 remaining failing files ?

(2) or run only python3-certified tests and check that they pass on your machine ?

I am doing (1) after almost every beta release. I have never tried (2), although I vaguely remember that Samuel Lelievre once asked for something like that, and I may have prepared the ground for it (I forgot about that), but never for any feedback.

It is not clear to me whether or not the "--with-python=3" in configure is robust enough to survive all patchbots cleaning operations.

I see that you tried option (2). Not quite successful, it seems.

Your patchbot shows a failure in

sage -t --long src/sage/modular/pollack_stevens/padic_lseries.py

Does it pass when you run it manually ?

Yes, I was asking about that a while ago, and it took me

a while to experiment and to set things up. I think I now

have two patchbots trying out tickets:

- one for Python2-based SageMath,

- one for Python3-based SageMath.

Let me know if you spot anything wrong with my setup.
