AIX uses iso8859-1 in the C locale, not ASCII
AIX doesn't currently provide any of the locale
coercion locales, but we leave locale coercion
enabled in case one gets added in the future.
- On some versions of FreeBSD, setting the "UTF-8" locale
succeeds, but a subsequent "nl_langinfo(CODESET)" fails
- adding a check for this in the coercion logic means that
coercion will happen on systems where this check succeeds,
and will be skipped otherwise
- that way CPython should automatically adapt to changes in
platform behaviour, rather than needing a new release to
enable coercion at build time
- this also allows UTF-8 to be re-enabled as a coercion
target, restoring the locale coercion behaviour on Mac OS X
- removes PY_WARN_ON_C_LOCALE build time flag
- locale coercion and compatibility warnings are now always compiled
in, but are off by default
- adds PYTHONCOERCECLOCALE=warn runtime option to aid in
debugging potentially locale related compatibility problems
Due to not-yet-resolved test failures on *BSD systems (including
Mac OS X), this also temporarily disables UTF-8 as a locale coercion
target, and skips testing the interpreter's behavior in the POSIX locale.
In the C locale on Mac OS X, the default filesystem encoding
used for operating system interfaces is UTF-8, but the
default encoding used on the standard streams is still ASCII.
Setting the POSIX locale also behaves differently from setting
other locales on Mac OS X, so skip that in the test suite for now.
When checking for reference leaks, test_c_locale_coercion is run
multiple times and so _LocaleCoercionTargetsTestCase.setUpClass() is
called multiple times. setUpClass() appends new value at each call,
so it looks like a reference leak.
Moving the setup from setUpClass() to setUpModule() avoids
this, eliminating the false alarm.
- new PYTHONCOERCECLOCALE config setting
- coerces legacy C locale to C.UTF-8, C.utf8 or UTF-8 by default
- always uses C.UTF-8 on Android
- uses `surrogateescape` on stdin and stdout in the coercion
target locales
- configure option to disable locale coercion at build time
- configure option to disable C locale warning at build time
