[issue21363] io.TextIOWrapper always closes wrapped files

[eryksun]

eryksun added the comment:

It works if you detach the buffer beforehand:

    >>> import io, sys
    >>> stdin = sys.stdin
    >>> stdin.flush()
    >>> correct_stdin = io.TextIOWrapper(stdin.buffer, 'utf-8')
    >>> correct_stdin.readline()
    foobar
    'foobar\n'

    >>> correct_stdin.detach()
    <_io.BufferedReader name='<stdin>'>

    >>> del correct_stdin
    >>> stdin.readline()
    foobar
    'foobar\n'
