rewrite the parsing of field names to be more consistent wrt recursive expansion

2013-05-17T23:22:31+00:00

merge 3.3

2013-05-17T22:35:28+00:00

only recursively expand in the format spec (closes #17644)

Close #17694: Add minimum length to _PyUnicodeWriter

2013-04-17T21:02:17+00:00

 * Add also min_char attribute to _PyUnicodeWriter structure (currently unused)
 * _PyUnicodeWriter_Init() has no more argument (except the writer itself):
   min_length and overallocate must be set explicitly
 * In error handlers, only enable overallocation if the replacement string
   is longer than 1 character
 * CJK decoders don't use overallocation anymore
 * Set min_length, instead of preallocating memory using
   _PyUnicodeWriter_Prepare(), in many decoders
 * _PyUnicode_DecodeUnicodeInternal() checks for integer overflow

Add _PyUnicodeWriter_WriteSubstring() function

2013-04-02T23:48:39+00:00

Write a function to enable more optimizations:

 * If the substring is the whole string and overallocation is disabled, just
   keep a reference to the string, don't copy characters
 * Avoid a call to the expensive _PyUnicode_FindMaxChar() function when
   possible

Remove unused defines.

Issue #14993: Use standard "unsigned char" instead of a unsigned char bitfield

Issue #14744: Use the new _PyUnicodeWriter internal API to speed up str%args and str.format(args)

2012-05-29T10:57:52+00:00

 * 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.

Rename unicode_write_t structure and its methods to "_PyUnicodeWriter"

Issue #14744: Inline unicode_writer_write_char() and unicode_write_str()

2012-05-09T20:24:08+00:00

Optimize also PyUnicode_Format(): call unicode_writer_prepare() only once
per argument.
