* | | Issue #15609: Optimize str%args for integer argumentVictor Stinner2012-10-011-67/+101
|/ / | | | | | | | | | | | | | | | | | | - 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

* | Issue #14744: Use the new _PyUnicodeWriter internal API to speed up str%args ↵Victor Stinner2012-05-291-97/+265
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
