Hi, all! strdup implementation inside cpython/Python/strdup.c is not the best one. It calls strlen + strcpy, which is the same as calling strlen twice + memcpy. So I replaced it by the call of strlen + memcpy. It is easy to look any implementation in any library. Here for example: https://code.woboq.org/userspace/glibc/string/strdup.c.html So I fixed it here: https://github.com/python/cpython/pull/21544 ---------- components: C API messages: 373955 nosy: fj92f3jj923f923 priority: normal severity: normal status: open title: Not very good strcpy implementation in cpython/Python/strdup.c type: performance versions: Python 3.10 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue41340> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
