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

6099a03202 Issue #13624: Write a specialized UTF-8 encoder to allow more optimization

f8eac00779 Issue #13623: Fix a performance regression introduced by issue #12170 in 
bytes.find() and handle correctly OverflowError (raise the same ValueError than
the error for -1).

0a3229de6b Issue #13417: speed up utf-8 decoding by around 2x for the non-fully-ASCII case. 
This almost catches up with pre-PEP 393 performance, when decoding needed
only one pass.

7931d9a951 Replace PyUnicodeObject type by PyObject 
* _PyUnicode_CheckConsistency() now takes a PyObject* instead of void*
 * Remove now useless casts to PyObject*
 2011-11-04 00:22:48 +01:00
Victor Stinner
9db1a8b69f Replace PyUnicodeObject* by PyObject* where it was irrevelant 
A Unicode string can now be a PyASCIIObject, PyCompactUnicodeObject or
PyUnicodeObject. Aliasing a PyASCIIObject* or PyCompactUnicodeObject* to
PyUnicodeObject* is wrong

4574e62c6e Fix massive slowdown in string formatting with str.format. 
Example:
./python -m timeit -s "f='{}' + '-' * 1024 + '{}'; s='abcd' * 16384" "f.format(s, s)"

-> before: 547 usec per loop
-> after: 13 usec per loop
-> 3.2: 22.5 usec per loop
-> 2.7: 12.6 usec per loop

c3cec7868b Add asciilib: similar to ucs1, ucs2 and ucs4 library, but specialized to ASCII 
ucs1, ucs2 and ucs4 libraries have to scan created substring to find the
maximum character, whereas it is not need to ASCII strings. Because ASCII
strings are common, it is useful to optimize ASCII.
