Python 3.8 is planned to be released at 2019-10-20. It's just before 2.7 EOL. My current thought is: * In 3.8, we make sure deprecated API emits warning (compile time if possible, runtime for others). * If the deprecation is adopted smoothly, drop them in 3.9 (Mid 2021). Otherwise, removal is postponed to 3.10 (Late 2023). > > There are other functions which expect that data is aligned to sizeof(long) > or 8 bytes. > > Siphash hashing is special because it is called not just for strings and > bytes, but for memoryview, which doesn't guarantee any alignment. > Oh, I'm sad about hear that... > Note that after removing the wchar_t* field the gap will not gone, because > the size of the structure should be a multiple of the alignment of the first > field (which is a pointer). Of course, we need hack for packing. -- INADA Naoki <songofaca...@gmail.com> _______________________________________________ Python-Dev mailing list Python-Dev@python.org https://mail.python.org/mailman/listinfo/python-dev Unsubscribe: https://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
