way to ensure the connection is complete

[dzen]

Hello,

we've got an error when the conection / initialization is still ongoing: https://github.com/jonathanslenders/asyncio-redis/blob/master/asyncio_redis/protocol.py#L832

we cannot be sure that this task is finished before starting to talk to redis (for instance, reading a pubsub), so our code ends at https://github.com/jonathanslenders/asyncio-redis/blob/master/asyncio_redis/protocol.py#L664.

Is there a way to not set an asyncio.sleep() and let us know if we're correctly connected to redis ?

Thank you.

What I have been using so far to make sure I connect to services like Redis is asyncio.wait_for.

Here is an example of how I make sure I'm connected:

async def connect():
  connection_made = False

  while not connection_made:
    try:
      connection = await asyncio.wait_for(asyncio_redis.Pool.create(
          host='localhost', port=6379, poolsize=20, db=0), 3.0)
      connection_made = True
    except asyncio.TimeoutError:
      print('having trouble connecting to redis')
      # let's try again
      continue

  print('connected to redis')

Well, Pool.create has the same pattern, that uses asyncio.async or such, which is the same pattern :(

Still, the future will be never consumed.
