New submission from Matthew Woodcraft:
I have a system where the default locale is C.UTF-8, and en_US.UTF-8 is
not installed.
But locale.normalize() unhelpfully converts "C.UTF-8" to "en_US.UTF-8".
So the following crashes for me:
python3.6 -c "import locale;locale.setlocale(locale.LC_ALL, ('C', 'UTF-8'))"
Similarly getdefaultlocale() returns ('en_US', 'UTF-8'), so this crashes too:
export LANG=C.UTF-8
unset LC_CTYPE
unset LC_ALL
unset LANGUAGE
python3.6 -c "import locale;locale.setlocale(locale.LC_ALL,
locale.getdefaultlocale())"
This behaviour is caused by a locale_alias entry in Lib/locale.py .
https://bugs.python.org/issue20076 documents its addition but doesn't
provide a rationale.
I can see that it might be helpful to provide such a conversion if
C.UTF-8 doesn't exist and en_US.UTF-8 does, but the current code is
breaking modern correctly-configured systems for the benefit of old
misconfigured ones (C.UTF-8 shouldn't really be in the environment if it
isn't available on the system, after all).
