New submission from INADA Naoki <songofaca...@gmail.com>: flags exposed by re module are IntFlag from Python 3.4.
Since it is passed to underlying sre_parse and sre_compile, tests in loop (e.g. `flags & SRE_FLAG_IGNORECASE`) calls IntFlag.__and__ and creates new instance everytime. It makes re.compile() slower. ---------- components: Library (Lib) messages: 303594 nosy: inada.naoki priority: normal severity: normal status: open title: IntFlag makes re.compile slower versions: Python 3.7 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue31671> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
