STINNER Victor <victor.stin...@haypocalc.com> added the comment: textiowrapper_interlaced_read_write.patch: TextIOWrapper.write() calls self.seek(self.tell()) if it has a decoder or if snapshot is not None.
I suppose that we can do better, but at least it does fix this issue. "read(); write(); write()" only calls self.seek(self.tell()) once, at the first write. So I don't think that it changes anything with performances. In which case snapshot can be not different than None, whereas decoder is None? ---------- keywords: +patch Added file: http://bugs.python.org/file22192/textiowrapper_interlaced_read_write.patch _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue12215> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
