Serhiy Storchaka added the comment: The patch slows down decoding up to 20%.
$ ./python -m timeit -s 'b = b"\xc4\x80"*10000' -- 'b.decode()' Unpatched: 10000 loops, best of 3: 50.8 usec per loop Patched: 10000 loops, best of 3: 63.3 usec per loop And I'm not sure that fixing only for the surrogatepass handler is enough. Other standard error handlers look working, but what if a user handler consumes more then one byte? ---------- components: +Interpreter Core priority: normal -> high _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue24214> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
