New submission from STINNER Victor <victor.stin...@gmail.com>: It seems like that some methods of the io.TextIOWrapper class requires that its buffer object has the read1() method, whereas the constructor checks if the buffer has a read1() method and the TextIOWrapper _read_chunk() method is able to call buffer.read() if buffer doesn't have read1().
This issue may help to get fully unbuffered sys.stdin, at least when replaced manually: stdin = sys.stdin sys.stdin = open(0, "r", buffering=0, encoding=stdin.encoding, errors=stdin.errors, newline=stdin.newline) ---------- components: IO messages: 304250 nosy: haypo priority: normal severity: normal status: open title: Support unbuffered TextIOWrapper versions: Python 3.7 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue31775> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
