> Why not simply EOFError?

IncompleteReadError has two additionnal attributes: - partial: "incomplete" received bytes - expected: total number of expected bytes (n parameter of readexactly) I prefer to use a different exception to ensure that these attributes are present. I don't like having to check "hasattr(exc, ...)". Before this change, readexactly(n) returned the partial received bytes if the end of the stream was reached. I had the same doubt. Note also that IncompleteReadError is a subclass of EOFError, so you can catch EOFError if you like.

Oops, I forgot to mention that :-) I just documented the new IncompleteReadError in asyncio doc.
