* Remove unused SSLProtocol._closing attribute
* test_sslproto: skip test if ssl module is missing
* Python issue #23208: Don't use the traceback of the current handle if we
  already know the traceback of the source. The handle may be more revelant,
  but having 3 tracebacks (handle, source, exception) becomes more difficult to
  read. The handle may be preferred later but it requires more work to make
  this choice.

Remove unneeded dummy test from the set search loop (when the hashes match we know the key is not a dummy).

Instead of masking and shifting every loopup, move the wrap-around
test outside of the inner-loop.

There was a bug which was fixed. The unit test was also wrong.

If ReadFile() fails with ERROR_BROKEN_PIPE, the operation is not pending: don't
register the overlapped.

I don't know if WSARecv() can fail with ERROR_BROKEN_PIPE. Since
Overlapped.WSARecv() already handled ERROR_BROKEN_PIPE, let me guess that it
has the same behaviour than ReadFile().

If UnregisterWaitEx() fais with ERROR_IO_PENDING, it doesn't mean that the wait
is unregistered yet. We still have to wait until the wait is cancelled.

Explicitly cast the long to char.

PyUnicode_EncodeCodePage() now raise an exception if the object is not an
Unicode object. For PyUnicode_EncodeFSDefault(), it was already the case on
platforms other than Windows. Patch written by Campbell Barton.

Use a coroutine with asyncio.sleep() instead of call_later() to ensure that the
schedule call is cancelled.

Add also a unit test cancelling connect_pipe().

If a client connected before the server was closed: drop the client (close the
pipe) and exit.

non-seekable streams.

threadsafe now.
