New submission from STINNER Victor <vstinner at redhat.com>:
AMD64 Fedora Rawhide Clang Installed 3.7:
https://buildbot.python.org/all/#/builders/195/builds/104
FAIL: test_env_var (test.test_utf8_mode.UTF8ModeTests)
----------------------------------------------------------------------
Traceback (most recent call last):
File "/home/buildbot/buildarea/3.7.cstratak-fedora.installed/build/target/lib/python3.7/test/test_utf8_mode.py", line 93, in test_env_var
self.assertEqual(out, '0')
AssertionError: '1' != '0'

On the buildbot:
vstinner at python-builder-rawhide$ env|grep -E 'LC_|LANG'
LANG=en_US.UTF-8
vstinner at python-builder-rawhide$ locale
locale: Cannot set LC_CTYPE to default locale: No such file or directory
locale: Cannot set LC_MESSAGES to default locale: No such file or directory
locale: Cannot set LC_ALL to default locale: No such file or directory
LANG=en_US.UTF-8
LC_CTYPE="en_US.UTF-8"
(...)
LC_ALL=
Extract of the test:
# Cannot test with the POSIX locale, since the POSIX locale enables
# the UTF-8 mode
if not self.posix_locale():
# PYTHONUTF8 should be ignored if -E is used
out = self.get_output('-E', '-c', code, PYTHONUTF8='1')
self.assertEqual(out, '0')
The problem seems to be posix_locale() which fails if the C locale has been coerced by PEP 538:
POSIX_LOCALES = ('C', 'POSIX')
def posix_locale(self):
loc = locale.setlocale(locale.LC_CTYPE, None)
return (loc in POSIX_LOCALES)
This code doesn't work if LC_CTYPE is already coerced.
