Getting returning True from eof_received() has no effect when using ssl

[thierryba]

Observed behavior

when I create a client with TLS on, it works but when I can drain, I am getting a message:
returning True from eof_received() has no effect when using ssl

Expected behavior

That message should not show.

Server and client version

nats-server: v2.10.12
nats_py-2.7.2

Host environment

macOS 14

Steps to reproduce

my code is really just doing this (contains TLS client certificate too):
nats_client = await nats.connect(**create_nats_options('FW Clients', err_cb))
await nats_client.drain()

and that shows the error.

Just wanted to add that we started getting this message when upgrading a project from python 3.10 to 3.11.

Same here: warning sslproto.py _call_eof_received():811: returning true from eof_received() has no effect when using ssl

Also seeing this when migrating from 3.10 to 3.11

Still an issue with python 3.12. This is a known issue with a known fix. The proposed solution solves the issue in nats.py as well, i.e. calling protocol.connection_made(transport) in TcpTransport.connect_tls().

@vetlesim Thank your very much. I change my local nats/aio/transport.py and it solve my problem

If you are brave enough you can also silence the asyncio warnings until the issue is solved

import logging

# Silence sslproto warning
logging.getLogger("asyncio").setLevel("ERROR")
