asyncsrv.py problem, the example doesn't work about zguide

[hintjens]

Strange, I don't have an asyncsrv.pl example in the repository... did you write it?

[pmarques]

Sorry, my fault. is not the perl that i'm talking about, but the python that is in the repo. (I have also changed the issue title)

[felipecruz]

Sorry, I should tell that on my first post...
The client shouldn't receive any response? AFAICS the client doesn't receive any response.
The patch is what change to able the messages to be send to the clients. Actually i don't understand why the first change is needed (the change of while "scope" by the device call) but it doesn't work before it.

i'll take a look.. what zmq version are you using?

[pmarques]

the pyzmq is the last one from your repository and if 'm not wrong the ZMQv2.1.7 (I don't have access to the PC on i have done that)
EDIT:
The ZMQ version was confirmed, 2.1.7

Felipe, thanks for looking at Patrick's issue. If/when you have a new version of asyncsrv.py, give me a shout. :-)

[felipecruz]

Patrick.. sorry about so late reply

as far as i can see it is ok (i've also tested it). but.... I now understand why the while loop is not running before, (line 62) and in this version the problem persistes when the server frontend receive a message... you should use the same work flow there. This is the diff(erences):

65a66
>                     _id = frontend.recv()
67c68,69
<                     print 'Server received %s\n' % (msg)
---
>                     print 'Server received %s id %s\n' % (msg, _id)
>                     backend.send(_id, zmq.SNDMORE)

done.

pulling.

thanks man!
