How to check when python-memcached server could not be connected

I was using python-memcached, and the process was going on even though the server I was connecting to was dead, so I was a little troubled.

Cause

memcache.py

    def _set(self, cmd, key, val, time, min_compress_len = 0):
        self.check_key(key)
        server, key = self._get_server(key)
        if not server:
            return 0

When set, 0 is returned even if there is no server.

memcache.py

    def _get(self, cmd, key):
        self.check_key(key)
        server, key = self._get_server(key)
        if not server:
            return None

None will come back even if you get it or there is no server.

With this, I don't know if the value is not actually set and it is None, or if there is no server and it is None.

Solution

I don't think this is correct, but it seemed to be identifiable, so for the time being.

client = memcache.Client(['192.168.1.1:11211'])
		
if len(client.get_stats()) == 0:
	raise Exception('Kestrel server not connected.')

The stats () function fetches each server status, but it doesn't seem to fetch it unless it's connected.

I thought it would be okay to set a value that shortened the lifespan and check if 0 was returned ... Isn't that better in terms of the number of server connections? w
