[zeromq-dev] Pub/Sub problem using sleep

I have recently started to evaluate 0MQ, and as part of this evaluation I was trying the Pub/Sub example (Weather update client & server) from the guide. I compiled the C++ version and everything appeared to work fine. I then tried updating the server, to slow down its rate of transmission. I a

Give us a link (use pastie.org, gist.github.com, etc) of the *exact same* code you are compiling and running. We need to see what you are doing. cr On Oct 29, 2012, at 3:18 AM, Ineil wrote: > I have recently started to evaluate 0MQ, and as part of this evaluation I was > trying the Pub/Sub exa

Re: [zeromq-dev] Pub/Sub problem using sleep

The server code is available at: https://gist.github.com/3972502 The server code does not work as posted, but does work with the sleep commented out. The client code comes straight from the zeromq guide. Regards, Dave. On 29 Oct 2012, at 08:22, Chuck Remes wrote: > Give us a link (use pas

[zeromq-dev] zmq_abort called from clean_pipes - is this a bug?

I managed to make the zeromq library (3.2.1-rc2) crash due to a programming error from outside the library. I know someone is going to ask for a small test case which may take me a little while to come up with, so for now a problem description. The library crashed like this: #0 0x00304b63

[zeromq-dev] CTRL+C

Hi, I have difficulties implementing a proper CTRL+C handling in my delphi binding. In the guide I read that : 'If your code is blocking in zmq_msg_recv(3) , zmq_poll(3) , or zmq_msg_send(3)

Re: [zeromq-dev] epgm performance numbers

Steve Throttling definitely helps. I reduced the HWM to 200 and added a 200 ms sleep every 50 samples and that brought down average round-trip times massively... So why is throttling helping?  -              Performance Report            

Re: [zeromq-dev] Pub/Sub problem using sleep

The server is sending approximately 10 Million messages for the 100 that need to be filtered on the client side [specific zipcode selected randomly among 100,000. The client waits for 100 of them]. If you sleep 1 second in the main server loop it will take forever. If you want to see what is going

[zeromq-dev] troubleshooting

Hello! First of all Thanks for the fantastic library! It's been a pleasure to use and I'm thinking about releasing my "zmq server builder" ruby code if I can get it more stable. Think Rack for zmq with some goodies like hmac msg auth and throttling. Anyway on to my dilemma. I'm working on a ne
