A problem with reconnect

[bofm]

When a Tarantool instance I am connected to with asynctnt crashes the Connection.connect() method blocks forever despite connect_timeout is set.

# pip install asynctnt

import asynctnt
import asyncio
import logging
from asynctnt.exceptions import TarantoolNotConnectedError

logging.basicConfig()


async def main():
    c = asynctnt.Connection(
        host='localhost',
        port=3301,
        connect_timeout=5,
        request_timeout=5,
        reconnect_timeout=0,
    )
    try:
        while True:
            if not c.is_connected:
                await c.connect()  # <------------- Hangs here after the Tarantool instance crashes
                print('connected')
            try:
                input('press any key to segfalt...')
                await c.eval('''require('ffi').cast('char *', 0)[0] = 48''')
            except TarantoolNotConnectedError as e:
                print('EXCEPTION:', e.__class__.__name__, e)
    finally:
        await c.disconnect()
        print('disconnected')


asyncio.run(main())

Output

$ python t.py
connected
press any key to continue...
EXCEPTION: TarantoolNotConnectedError Lost connection to Tarantool
