gh-93033: Use wmemchr in stringlib (GH-93034)
Generally comparable perf for the "good" case where memchr doesn't
return any collisions (false matches on lower byte) but clearly faster
with collisions.

bpo-46670: Define all macros for stringlib (GH-31176)

macros used by stringlib, to avoid using undefined macros.
Fix "gcc -Wundef" warnings.

Antoine Pitrou ca5f91b888 Issue #14738: Speed-up UTF-8 decoding on non-ASCII data. Patch by Serhiy Storchaka. 2012-05-10 16:36:02 +02:00
Victor Stinner 41a863cb81 Issue #13706: Fix format(int, "n") for locale with non-ASCII thousands separator
* Decode thousands separator and decimal point using PyUnicode_DecodeLocale()
   (from the locale encoding), instead of decoding them implicitly from latin1
 * Remove _PyUnicode_InsertThousandsGroupingLocale(), it was not used
 * Change _PyUnicode_InsertThousandsGrouping() API to return the maximum
   character if unicode is NULL
 * Replace MIN/MAX macros by Py_MIN/Py_MAX
 * stringlib/undef.h undefines STRINGLIB_IS_UNICODE
 * stringlib/localeutil.h only supports Unicode
