[Debian-astro-maintainers] Bug#923437: gnudatalanguage: flaky autopkgtest: TEST_L64: Array requires more memory than available

[Paul Gevers]

Source: gnudatalanguage
Version: 0.9.9-8
Severity: important
User: debian-ci at lists.debian.org
Usertags: flaky

Dear maintainers,

With a recent upload of python3.7 the autopkgtest of gnudatalanguage
fails in testing when that autopkgtest is run with the binary packages
of python3.7 from unstable. I looked at the error (which I copied below)
and noticed that the same error appears (randomly it seems) on the
ci.debian.org infrastructure. Hence, I deduced that your test is flaky.

I see multiple solutions for this, I have no idea how complicate some of
them are:
1) don't run (skip) this test if it can be determined that there is not
enough memory
2) don't fail this specific test if the amount of memory is not available
3) add the flaky restriction to the test-gdl test, but than any other
failure will also not be detected anymore.

Paul
