Victor Stinner 621ef3d84f Issue #15609: Optimize str%args for integer argument
- Use _PyLong_FormatWriter() instead of formatlong() when possible, to avoid
   a temporary buffer
 - Enable the fast path when width is smaller or equals to the length,
   and when the precision is bigger or equals to the length
 - Add unit tests!
 - formatlong() uses PyUnicode_Resize() instead of _PyUnicode_FromASCII()
   to resize the output string

Victor Stinner c9d369f1bf Optimize _PyUnicode_FastCopyCharacters() when maxchar(from) > maxchar(to) 2012-06-16 02:22:37 +02:00
Victor Stinner d3f0882dfb Issue #14744: Use the new _PyUnicodeWriter internal API to speed up str%args and str.format(args)
* Formatting string, int, float and complex use the _PyUnicodeWriter API. It
   avoids a temporary buffer in most cases.
 * Add _PyUnicodeWriter_WriteStr() to restore the PyAccu optimization: just
   keep a reference to the string if the output is only composed of one string
 * Disable overallocation when formatting the last argument of str%args and
   str.format(args)
 * Overallocation allocates at least 100 characters: add min_length attribute
   to the _PyUnicodeWriter structure
 * Add new private functions: _PyUnicode_FastCopyCharacters(),
   _PyUnicode_FastFill() and _PyUnicode_FromASCII()

The speed up is around 20% in average.

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

Victor Stinner fb9ea8c57e Don't check for the maximum character when copying from unicodeobject.c
* Create copy_characters() function which doesn't check for the maximum
   character in release mode
 * _PyUnicode_CheckConsistency() is no more static to be able to use it
   in _PyUnicode_FormatAdvanced() (in formatter_unicode.c)
 * _PyUnicode_CheckConsistency() checks the string hash

Victor Stinner 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.

Eric Smith 8c66326368 Implementation of PEP 3101, Advanced String Formatting.
Known issues:

The string.Formatter class, as discussed in the PEP, is incomplete.

Error handling needs to conform to the PEP.

Need to fix this warning that I introduced in Python/formatter_unicode.c:
Objects/stringlib/unicodedefs.h:26: warning: `STRINGLIB_CMP' defined but not used

Need to make sure sign formatting is correct, more tests needed.

Need to remove '()' sign formatting, left over from an earlier version of the PEP.
