txyam.client.NoServerError: No connected servers remaining. #7

Closed minskmaz closed 9 years ago

Yet here's my netstat:

(verymoody)vagrant@minskmaz:~/projects$ netstat -l | grep 11211 tcp 0 0 localhost:11211 : LISTEN
udp 0 0 localhost:11211 :

and I'm able to set and get from python-memcached.

Any suggestions warmly welcomed! Thank you

Are you able to connect at all? Or does it disconnect? Can you paste your connection code?

minskmaz commented 9 years ago

is there a debugging mode I can put it into ? 

def __setattr__(self, key, val):
    uid = str(uuid.uuid4())
    self._attrs[key] = uid
    hosts = ['localhost', ('127.0.0.1', 11211)]
    client = YamClient(hosts)
    client.set(uid, val).addCallback(self.handler)
minskmaz commented 9 years ago

it doesn't seem to connect at all - I will look at tcpflow to confirm if there's any activity

minskmaz commented 9 years ago

"sudo tcpflow -i lo -c port 11211" shows no activity

bmuller commented 9 years ago

Is your handler called? You just need to set up a logger, it logs messages via twisted.python.log.

minskmaz commented 9 years ago

no handler isn't called

bmuller commented 9 years ago

Have you added an errback?

minskmaz commented 9 years ago

no but I can I figured it was giving me the error anyhow - brb

minskmaz commented 9 years ago

I will try to insert into an existing project with a functional reactor. might be because I'm running code without rector present

bmuller commented 9 years ago

Yep, as a twisted lib a running reactor is a necessary prerequisite. I'll mark this one closed, then - though please do file another ticket if you run into any issues. Thanks!

It gives me the same error in a reactor:
