[issue21057] TextIOWrapper does not support reading bytearrays or memoryviews

[Martin v. Löwis]

Martin v. Löwis added the comment:

Nikolaus, can you please restate from scratch what the issue is? If the issue is still the one you posed in msg214776, I think the issue should be closed as "invalid" - it's *not* the case that there is no good reason for TextIOWrapper not accepting any bytes-like object. Or, to drop the double negation: as Serhiy states, read1() should return bytes, and it's perfectly fine to rely on that. Your MyByteStream ought to fail, so it is correct behaviour that it does fail.
