zeromq / cljzmq Goto Github PK

Hi there, I notice that there hasn't been any activity on this library in some time. Is it still maintained? If not should the readme be updated with a disclaimer?

The following sample doesnt work without the sleep statement, i have excluded jzmq and using jeromq. moreover i dont see any error.

(ns exp.distributed
  (:use [clojure.tools.logging :only (warn info error)])
  (:require [zeromq.zmq :as zmq]
            [clojure.core.async :as async :refer :all]))

(defn start-subs []
  (future
    (let [ctx (zmq/context 1)]
      (with-open [sub (doto (zmq/socket ctx :sub)
                        (zmq/connect "tcp://127.0.0.1:5556")
                        (zmq/subscribe "topic"))]
        (dotimes [i 10]
          (info (zmq/receive-str sub)))))
    (info "listeners quits.")))

(defn start-pubs []
  (future
    (let [ctx (zmq/context 1)]
      (with-open [pub (doto (zmq/socket ctx :pub)
                        (zmq/bind "tcp://*:5556"))]
        (Thread/sleep 1000);removing this doesnt works
        (dotimes [i 10]
          (zmq/send-str pub (format "topic %d" i)))))
    (info "publisher quits.")))

(do
    (start-subs)
    (start-pubs))

1. It seems there have been no commits for the past 1.5 years (latest commit 7a84f43 on Jan 6, 2015 as of this writing, July 13, 2016).
2. There were 19 commits (including merges) since 0.1.4
3. I'd be happy to do it myself, but I don't have the clojars permissions for this package.

Thank you.

I think we just need another multimethod.

(defmethod close org.zeromq.ZMQ$Context
  [^org.zeromq.ZMQ$Context zctx]
  (.term zctx))

Although i am little confused why doesnt cljzmq's context match with JeroMQ's ZContext.

if I create a project and add the cljzmq dep and try to require it, it fails trying to load jzmq, if I add it to the deps with something like:

:dependencies [[org.clojure/clojure "1.5.1"]                                 
             [org.zeromq/jzmq "2.2.1"]                                     
             [org.zeromq/cljzmq "0.1.1"]] 

it fails in the repl with

user=> (require '[zeromq.zmq :as zmq])

UnsatisfiedLinkError no jzmq in java.library.path  java.lang.ClassLoader.loadLibrary (ClassLoader.java:1856)

which is the recommended way to make it work?

I am a newbie so forgive my naive question in advance.

deftest send-str-timeout-test in zmq-test.clj returns the following exception:

clojure.lang.Compiler$CompilerException: java.lang.RuntimeException: No such var: zmq/set-send-timeout, compiling:(/Users/spaceshuttle/Documents/FP/Clojure/source_code/my-code/second-jzmq/test/second_jzmq/zmq-test.clj:26:20)

is this what I should be expecting? or did I go wrong somewhere? Thanks for your help in advance.

A few short examples would go a long way

I get the following reflection warning for cljzmq:
Reflection warning, zeromq/zmq.clj:161:6 - call to method send on org.zeromq.ZMQ$Socket can't be resolved (no such method).

Hello, trying to get the examples working, but am getting a java.lang.UnsatisfiedLinkError error. Here's my steps:

I installed the latest zeromq via brew:

joker:~ dan.young$ brew install zeromq
==> Downloading http://download.zeromq.org/zeromq-4.0.4.tar.gz
Already downloaded: /Library/Caches/Homebrew/zeromq-4.0.4.tar.gz
==> ./configure --prefix=/usr/local/Cellar/zeromq/4.0.4
==> make
==> make install
==> Caveats
To install the zmq gem on 10.6 with the system Ruby on a 64-bit machine,
you may need to do:

ARCHFLAGS="-arch x86_64" gem install zmq -- --with-zmq-dir=/usr/local/opt/zeromq

Here's my project.clj:

(defproject zero-mq "0.1.0-SNAPSHOT"
:description "zero mq"
:url "http://example.com/FIXME"
:license {:name "Eclipse Public License"
:url "http://www.eclipse.org/legal/epl-v10.html"}

[org.zeromq/cljzmq "0.1.4"]]
:jvm-opts ["-Djava.library.path=/usr/lib:/usr/local/lib"]
:main zero-mq.rrbroker)

in my zero-mq.rrbroker

ns zero-mq.rrbroker
(:require [zeromq.zmq :as zmq]
))

(println (. System getProperty "java.library.path"))

then try to run lein repl

Exception in thread "main" java.lang.UnsatisfiedLinkError: no jzmq in java.library.path

at java.lang.System.loadLibrary(System.java:1044)

Any idea on what I'm doing wrong?

Presently, receive-str will raise a NullPointerException if a timeout occurs after (.setReceiveTimeOut socket timeout). I believe that it should return nil. What is the correct behavior?

I am getting the dreaded unsatisfied link error. I spent some time chasing it today. I notice that ldconfig does not create a softlink pointing libzmq.so.0 to blahblah/libmq.so.3 . Should it?
Why is cljzmq 0.1.4 looking for .0?
