[PATCH] scripts: Allow sha512 in clean_functional_cache.py, too
Posted by Thomas Huth 2 weeks, 3 days ago
From: Thomas Huth <thuth@redhat.com>

The functional testing frameworks also supports assets that are
identified by their sha512 checksum (instead of only using sha25),
and at least one of the tests (tests/functional/ppc64/test_fadump.py)
is already using such a checksum, so adjust the clean_functional_cache
script to support these checksums, too.

I wrote this code to match what we had in Avocado, but now I'm really
struggling to justify why we should choose different checksum algorithms
per asset. With only 1 test diverging from sha256, I'd rather we just
dropped sha512 support

Fine for me, too ... could you suggest a patch, or want me to do it?
