This makes it easy to track all the places that use config.yml, and
hopefully makes things feel cleaner. This also standardizes all places
where config.yml is written out to use UTF-8 as the file encoding.
This also includes a lot of black code format fixes.
This name always confuses me, since there is also test_common.py. And this
module is not actually a test suite, even though it starts with "test".
This also makes for better tab completion, e.g.
python3 -m unittest tests/te[Tab] -> tests/test_
ZipFile.namelist() produces a string per file. The filename could contain
newline chars, including at the beginning and end. ^$ in regex matches
around newline chars. \A\Z matches the beginning/end of the full string.
This is exactly the same as obfusk's r'\AMETA-INF/(?s:.)*\.(DSA|EC|RSA)\Z'
but in a readable format that is also easily searchable, and standard for
this code base.
