ALT_DIGITS is a glibc specific item. It is supported by Python (there is an explicit list of supported items), but the result is not correct.

From The GNU C Library Reference Manual:

ALT_DIGITS

The return value is a representation of up to 100 values used to represent the values 0 to 99. As for ERA this value is not intended to be used directly, but instead indirectly through the strftime function. When the modifier O is used in a format which would otherwise use numerals to represent hours, minutes, seconds, weekdays, months, or weeks, the appropriate value for the locale is used instead.

This value is only defined in few locales: az_IR, fa_IR, ja_JP, lzh_TW, my_MM, or_IN, shn_MM.

But Python returns only one digit.

>>> import locale
>>> locale.setlocale(locale.LC_TIME, 'ja_JP')
'ja_JP'
>>> locale.setlocale(locale.LC_CTYPE, 'ja_JP')
'ja_JP'
>>> locale.nl_langinfo(locale.ALT_DIGITS)
'〇'

This is because nl_langinfo(ALT_DIGITS) in C returns a string with embedded null characters.

How should we fix it?

  • return a single string with 99 embedded null characters
  • return a 100-tuple of strings

What should we return if the value is not defined (in most locales) -- empty string (current behavior), empty tuple or None?

    @freakboy3742: this fix broke the iOS buildbot. You might have opinions on how to handle this on non-glibc platforms :)

    It is interesting that ALT_DIGITS is a FreeBSD extension. And was inherited on Apple platforms. I wonder whether it is not set only for Japanese or for other locales (not installed on buildbots) too? fa_IR, lzh_TW, my_MM, or_IN, shn_MM?

    @serhiy-storchaka AFAICT, jp_JP is the only locale in test test set that is defined, and it isn't defining a value for ALT_DIGITS. The others fall back as an unrecognised locale. Whether that can be fixed by installing something else on the buildbot/test machine, I can't say - but I haven't explicitly installed a JP locale on my machine.

    Thank you for pointing on this @kulikjak. It was used in Python sources as optionally defined, and it was not even documented in Linux manpages, so I thought that it is a unofficial extension.

    Does it mean that locale.nl_langinfo(locale.ALT_DIGITS) now crashes on Solaris? What was the output of the following script on still working Python?

    import locale, subprocess
alllocales = subprocess.check_output(['locale', '-a']).decode().split()
for loc in alllocales:
    if '.' in loc or '@' in loc:
        continue
    try:
        _ = locale.setlocale(locale.LC_ALL, loc)
    except locale.Error:
        continue
    alt_digits = locale.nl_langinfo(locale.ALT_DIGITS)
    if alt_digits:
        print(loc, len(alt_digits), alt_digits)

    On Linux I now get

    ... I thought that it is a unofficial extension.

    Oh I get that - I didn't even know it existed before the test started failing :).

    Does it mean that locale.nl_langinfo(locale.ALT_DIGITS) now crashes on Solaris? What was the output of the following script on still working Python?

    It doesn't crash, only the test fails with:

    Traceback (most recent call last):
  File "/..../Lib/test/test__locale.py", line 214, in test_alt_digits_nl_langinfo
    self.assertEqual(len(alt_digits), count)

    I ran your script (with the '.' check removed as most of our locales have .UTF-8 or other suffix) on latest 3.13 and the output is:

    Thank you. Indeed, this looks like semicolon separated correct values.

    locale.nl_langinfo(locale.ALT_DIGITS) always returned an empty result on *BSD and macOS, and on Windows it just is not implemented, so Linux was the only tier 1 platform on which it worked, but was broken. But since the POSIX specification says that values should be semicolon separated, it seems, that glibc is broken. I understand why they did this, it is more convenient for the C code. On Python side, it would be more convenient to return a tuple, but this is breaking change on Solaris, the only platform that implemented it right. So I think that we should fix the glibc implementation and return a semicolon separated string. I hope that no locale uses semicolon as an alternative digit or in the ERA items.

    Makes sense, although I think that if we want the tuple (which is indeed nicer on the Python side), we can implement alternative parsing (for Solaris and possibly other more compliant platforms) that uses ; rather than \0 as a separator as well.

    It is interesting that a similar issue was fixed in Perl at the beginning of this year (Perl/perl5#21833). They return a single string, replacing null characters with semicolons. Actually, they support also other separators, but I do not think there is a reason to do this.
