unable to reconnect when using feature/asyncio branch of websocket.py

[CyrilleBoullier]

Hello,

I'm using the branch feature/asyncio and it works well.

However, due to binance deconneciton of the websocket, I sometime recieved following messages:

• ERROR code = 1006 (connection closed abnormally [internal]), no reason
• websockets.protocol DEBUG client ! timed out waiting for pong

and it seems that the API does not reconnect correctly.

I tried to reproduce it using following snippet:

import asyncio

from binance import AsyncClient, BinanceSocketManager

import logging
from logs_management import logToConsole
logToConsole(logging.INFO)

loop = None

async def main():
global loop

# initialise the client
client = await AsyncClient.create()

# initialise socket manager
bsm = BinanceSocketManager(client, loop)

# setup async callback handler for socket messages
async def handle_evt(msg):
    pair = msg['s']
    print(f'{pair} : {msg}')

# create listener, can use the `ethkey` value to close the socket later
key = await bsm.start_aggtrade_socket('BTCUSDT', handle_evt)

while True:
    print("doing a sleep")
    await asyncio.sleep(20, loop=loop)

if name == "main":

loop = asyncio.get_event_loop()
loop.run_until_complete(main())

The API tries to reconnect, I see the following line in DEBUG mode:
'websocket btcusdt@aggTrade reconnecting 4 reconnects left'

but it never manages to reconnect and the loop continues to write "doing a sleep" with nothing else.

investing in the file websocket.py, it seems that the line

'asyncio.sleep(reconnect_wait)'

never finish.

Could you please inestigate and help me to fix this issue?

Thanks a lot,
Cyrille.

Environment (please complete the following information):

• Python version: python 3.7

Is the branch feature/asyncio still active with developments?

Hello!
I developed an async websocket lib for binance which reconnects automatic:
