f = flask.request.files[input_name]

Files smaller than 1024 * 500 bytes are written to a StringIO object, while files greater than that threshold are written to temporary files.

It's part of Werkzeug's testing framework, but that function isn't part of the online documentation:

def stream_encode_multipart(values, use_tempfile=True, threshold=1024 * 500,
                            boundary=None, charset='utf-8'):
    """Encode a dict of values (either strings or file descriptors or
    :class:`FileStorage` objects.) into a multipart encoded string stored
    in a file descriptor.
    """

    ...
