[New-bugs-announce] [issue34975] start_tls() difficult when using asyncio.start_server()

[Ian Good]

New submission from Ian Good <icgood at gmail.com>:

There does not seem to be a public API for replacing the transport of the StreamReader / StreamWriter provided to the callback of a call to asyncio.start_server().

The only way I have found to use the new SSL transport is to update protected members of the StreamReaderProtocol object, e.g.:

    async def callback(reader, writer):
        loop = asyncio.get_event_loop()
        transport = writer.transport
        protocol = transport.get_protocol()
        new_transport = await loop.start_tls(
            transport, protocol, ssl_context, server_side=True)
        protocol._stream_reader = StreamReader(loop=loop)
        protocol._client_connected_cb = do_stuff_after_start_tls
        protocol.connection_made(new_transport)

    async def do_stuff_after_start_tls(ssl_reader, ssl_writer): ...
