* | Close #17694: Add minimum length to _PyUnicodeWriterVictor Stinner2013-04-171-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | * 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

| | | | | | | | | | | | | | efficient machine code. Patch written by Antoine Pitrou. Without this change, str.find() was 10% slower than str.rfind() in the worst case.
* | Add _PyUnicodeWriter_WriteSubstring() functionVictor Stinner2013-04-021-12/+6
| | | | | | | | | | | | | | | | | | 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

| | | | | | | | | | | | | | | | | 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.
