Result of test_remove_cells_boundary() is hardware-dependent

[sanvila]

Hello. This issue was discovered while building all Debian packages from source.

In some systems, test_remove_cells_boundary() from tests/test_remove_cells.py always fails:

    def test_remove_cells_boundary():

tests/test_remove_cells.py:104: AssertionError

The outcome seems to be hardware-dependent. On AWS instances of type c7a.large and c7i.large, the test always fails. These are the specs:

https://aws.amazon.com/es/ec2/instance-types/c7a/ https://aws.amazon.com/es/ec2/instance-types/c7i/

We (Debian) will probably disable the test in the meantime, as we want everybody to be able to build Debian packages from source.

Thanks.

What version of meshplex?

[sanvila]

Version 0.17.1

Edit: Oh, I see there is version meshplex 0.19.7 in pypi.org. We could try to update the package first, assuming it still has a license which is compatible with the Debian Free Software Guidelines. I'll ask the usual maintainer (as I'm just doing general Debian QA work).

[nschloe]

We no longer support that version.

It doesn't.
