* | Optimize backslashreplace error handlerVictor Stinner2015-10-081-2/+16
| | | | | | | | | | | | | | | | | | | | Issue #25318: Optimize backslashreplace and xmlcharrefreplace error handlers in UTF-8 encoder. Optimize also backslashreplace error handler for ASCII and Latin1 encoders. Use the new _PyBytesWriter API to optimize these error handlers for the encoders. It avoids to create an exception and call the slow implementation of the error handler.
* | Issue #25318: Add _PyBytesWriter APIVictor Stinner2015-10-081-63/+21
| | | | | | | | | | | | | | | | | | | | | | Add a new private API to optimize Unicode encoders. It uses a small buffer allocated on the stack and supports overallocation. Use _PyBytesWriter API for UCS1 (ASCII and Latin1) and UTF-8 encoders. Enable overallocation for the UTF-8 encoder with error handlers. unicode_encode_ucs1(): initialize collend to collstart+1 to not check the current character twice, we already know that it is not ASCII.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The utf-16* and utf-32* encoders no longer allow surrogate code points (U+D800-U+DFFF) to be encoded. The utf-32* decoders no longer decode byte sequences that correspond to surrogate code points. The surrogatepass error handler now works with the utf-16* and utf-32* codecs. Based on patches by Victor Stinner and Kang-Hao (Kenny) Lu.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Remove an unused early-out test from the critical path for dict and set lookups. When the strings already have matching lengths, kinds, and hashes, there is no additional information gained by checking the first characters (the probability of a mismatch is already known to be less than 1 in 2**64).
