EofStream and autoclose

[thomaszdxsn]

Long story short

Hi, I meet a problem with websocket's client message, sometimes I will receive EofStream object instead of bytes or str(so broken my program).I don't now what's this object.But I guess it means EOF right?

async for msg in self._ws_conn:
    msg_data = json.loads(msg_data)  # msg_data maybe EofStream

Expected behaviour

If EofStream meaning EOF, Why not just close this websocket connection, beacuase I see ws_connect() have a argument named 'autoclose', it default to True?

Or EofStream has other meaning?

Is it aiohttp 3.0?

[thomaszdxsn]

"version": "==3.0.6"

It's my pipfile.lock's content

[asvetlov]

This is a bug, iteration over websocket messages should be stopped without returning stop marker to user.
Would you work on bugfix?

[thomaszdxsn]

yeah, i should take time to read contribute guide

Fixed by #2814, released by aiohttp 3.1

aiohttp 3.8.1

await websocket.receive_json() Will die with TypeError on WSMsgType.CLOSED.

 async def __anext__(self) -> WSMessage:
        msg = await self.receive()
        if msg.type in (WSMsgType.CLOSE, WSMsgType.CLOSING, WSMsgType.CLOSED):
            raise StopAsyncIteration
        return msg

Yes, bug is fixed in iterator but NOT fixed for websocket.receive_* functions, like receive_json()

I would raise RuntimeError or so if corresponding message "type" (like bytes, str, or json) can not be received.
