[issue30755] locale.normalize() and getdefaultlocale() convert C.UTF-8 to en_US.UTF-8
Gordon Messmer added the comment: As an example, let's consider dnf's i18n setup: try: dnf.pycomp.setlocale(locale.LC_ALL, '') except locale.Error: # default to C.UTF-8 or C locale if we got a failure. try: dnf.pycomp.setlocale(locale.LC_ALL, 'C.UTF-8') os.environ['LC_ALL'] = 'C.UTF-8' except locale.Error: dnf.pycomp.setlocale(locale.LC_ALL, 'C') os.environ['LC_ALL'] = 'C' If setting the environment-specified locale fails, dnf will attempt to set the locale to C.UTF-8, and if that fails it will set the locale to C. This seems like an ideal process. If the expected locale is missing, dnf will attempt to at least use UTF-8, before falling back to the C locale. Unfortunately, because of the alias, this process will be unable to set the 'C.UTF-8' locale on systems which do not have the 'en_US' locale installed. This renders system support for 'C.UTF-8' unusable when no locales are installed. -- ___ Python tracker <https://bugs.python.org/issue30755> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue30755] locale.normalize() and getdefaultlocale() convert C.UTF-8 to en_US.UTF-8
Gordon Messmer added the comment: > I agree we shouldn't be aliasing C.UTF-8 to en_US.UTF-8 though What can we do about reverting that change? Python's current behavior causes unexpected exceptions, especially in containers. I'm currently debugging test failures in a Python application that occur in Fedora rawhide containers. Those containers don't have any locales installed. The test software saves its current locale, changes the locale in order to run a test, and then restores the original. Because Python is incorrectly reporting the original locale as "en_US", restoring the original fails. -- ___ Python tracker <https://bugs.python.org/issue30755> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue30755] locale.normalize() and getdefaultlocale() convert C.UTF-8 to en_US.UTF-8
Gordon Messmer added the comment: > 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 That can't happen. The "C" locale describes the behavior defined in the ISO C standard. It's built-in to glibc (and should be for all other libc implementations). All other locales require external support (i.e. /usr/lib/locale/) https://www.gnu.org/software/libc/manual/html_node/Standard-Locales.html#Standard-Locales -- nosy: +gordonmessmer ___ Python tracker <https://bugs.python.org/issue30755> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue34138] imaplib RFC 6855 issue
Gordon Messmer added the comment:
PR 9436 should resolve the issue.
Since the RFC requires the "UTF8 (" prefix in the "data" and not in the
literal, that had to be moved into the _command function.
This change should only affect the append() use, as that is currently the only
function that sets self.literal to a value that is not a function. The
authenticate() use is not affected, and no other functions set self.literal.
