Description (last modified by saraedum)

The patchbots time out with some lattice precision tests I have also seen the same issues with GitLab? CI tests.

The test suite takes too much time, more precisely _test_matrix_smith.

sage: R = QpLC(7, label='init')
sage: %time TestSuite(R).run(skip='_test_teichmuller')
Wall time: 2min 59s
sage: %time R._test_matrix_smith()
Wall time: 2min 56s

I have launched my patchbot having the timeout issue, to see if the branch brings any progress.

comment:7 Changed 7 months ago by chapoton

This indeed seems to fix the timeout issue (see petibonum report)

Note: my patchbot has found some pyflakes errors in the modified files, see the pyflakes plugin.

FYI: short doctests should take at most 1 second or so and long doctests at most 30 seconds (unless for exceptional reasons).

As noted on the mailing list, I am also getting

sage -t src/sage/rings/padics/
    Timed out (with segmentation fault after interrupt)

on cygwin. I will test this patch and see if the tests at least pass with these tests skipped by default (and I will also test with --long)
