compat: initialize LC_CTYPE locale on all Python versions and platforms...
compat: initialize LC_CTYPE locale on all Python versions and platforms Previously, the LC_CTYPE locale was not initialized according to user settings on all Python versions (e.g. never on Python 2) and platforms (e.g. not on some Python < 3.8 on Windows). This broke e.g. non-ASCII filenames passed to the Subversion bindings on Python 2, resulting in error messages like "file:///tmp/a%C3%A4 does not look like a Subversion repository to libsvn version 1.14.0". The following command could be used to test this functionality. Adding it to the test suite would be pointless, as the locale is always set to "C" during test runs. @command(b'check_initial_codeset', norepo=True) def check_initial_codeset(ui): codeset1 = locale.nl_langinfo(locale.CODESET) locale.setlocale(locale.LC_ALL, '') codeset2 = locale.nl_langinfo(locale.CODESET) assert codeset1 == codeset2
