Hi Pythonistas.
Regarding our Python 3 C.UTF-8 locale coercing [1], aka PEP 538 [2].
As you probably know, we build RPM packages with the C locale. So
everytime we use python3 in the spec file, the coercing message is
shown. This can be more problematic than just spamming the build logs,
see for example the related rpmlint bug [3][4].
Our macros, such as %{python3_sitelib}, %{python3_version} etc. all call
python3 and generate the warning. Should we "fix" our macros to set the
LANG to C.UTF-8?
If we change the %{__python3} macro entirely, we might get rid of all of
those warnings and we will workaround the fact that we build RPM
packages with the C locale. On the other hand the packager would not be
able to set a desired locale because it will always be overwritten:
# The crazy test suite needs Czech locale
LANG=cs_CZ.utf8 %{__python3} -m pytest
Will become:
LANG=cs_CZ.utf8 LANG=C.utf8 /usr/bin/python3 -m pytest
So I would not do that.
But we can change all other macros in
/usr/lib/rpm/macros.d/macros.python3 to set the UTF-8 locale. Would that
be wise? Desired?
Any thoughts?
