[New-bugs-announce] [issue12197] non-blocking SSL write in Windows sends large data but raises exception

[David Siroky]

New submission from David Siroky <siroky at dasir.cz>:

Trying to send large bulk of data in MS Windows via non-blocking SSLSocket raises an exception but part of the data is delivered.

E.g.

ssl_socket.write(b"a" * 200000)

raises

ssl.SSLError: [Errno 3] _ssl.c:1126: The operation did not complete (write)

There is no way to get the sent bytes count which is essential in non-blocking communication.

ssl_socket.send() returns 0. This should be unified with posix behavior.
