When using zeromq from c, req sockets don't allow sending twice.
The usage pattern is send, receive, send, receive ...
Receive is a blocking call.
Now, zeromq.node of course doesn't want to block and there isn't an explicit receive.
So it allows us to keep on sending. Because 0mq would normally throw an exception when sending twice before receiving, I'm assuming zeromq.node caches additional messages internally and waits for an answer before submitting the next.
This is nice, but I lose the ability to match an answer to a question.
Every reply will reach me through the same callback (socket.on('message', callback));
So I need to create queues where requesting code puts a callback in the queue, and the 1 on-message callback picks the first callback out of the queue and delegates there.
While this works, I don't think it's very nice to do this way.
How about something like:
var request = "3 + 3";
socket.send(request, function(reply) {
console.log(request, '=', reply);
});
Of course I can build a small wrapper lib myself, but I think this should be part of the zeromq.node api.
Do you agree? Or am I just doing something wrong here? :)
Hi -
Trying to use zeromq.node and while the install works fine I get an error as soon as a try and create a socket. I'm suing 0MQ v2.1.7 on OS X Lion.
Here's the code that's failing:
var zmq = require('zmq');
var socket = zmq.createSocket('req');
When I run it I get the following output:
$ node server.js
Starting server on port 8888
dyld: lazy symbol binding failed: Symbol not found: _zmq_init
Referenced from: /usr/local/lib/node_modules/zmq/binding.node
Expected in: flat namespace
dyld: Symbol not found: _zmq_init
Referenced from: /usr/local/lib/node_modules/zmq/binding.node
Expected in: flat namespace
Trace/BPT trap: 5
Any ideas?
Note that if I take out the createSocket() call it works so the module is being properly loaded, it just won't work if you try and interact with the context.
Thx
Mike
The samples in the readme still point to (possibly?) old naming?
Replacing require 'zeromq' to 'zmq' makes them work again.
The following code doesn't listen on the socket forever and should
var socket = zeromq.createSocket('pull');
socket.connect('tcp://127.0.0.1:45670');
socket.on('message', function(message) {
// do stuff with the message
});
util.puts('Ready to serve.');
The following code simply increments the currentSendBacklog
indefinitely
zeromq = require('zeromq');
util = require('util');
s = zeromq.createSocket('push');
// I would expect send to block after 3 messages
s['highWaterMark'] = 3
s['diskOffloadSize'] = 0
s.bind('tcp://127.0.0.1:5554', function(err) {
if (err) throw err;
setInterval(function() {
s.send('test')
util.puts("Current send backlog: " + s.currentSendBacklog())
}, 1000)
});
I can understand the motivation not to allow send to block the event loop, however this behaviour seems counter to the design of ZMQ. Am I missing something, or is this by design?
require('zeromq');
results in this error:
/libexec/ld-elf.so.1: /root/node_modules/zeromq/binding.node: Undefined symbol "_ZN2v811HandleScopeC1Ev"
OS:BSD, NODE V 0.4.8, zeromq.node version 0.5.0
Any thoughts? Would really like to use this in a production application,,, but cant seem to get things working.
npm install went off without a hitch, but cant require the lib without error.....
Thanks,
I'm seeing a lot of errors like this:
TypeError: Socket is closed
at [object Object]._ioevents (/data/nodeload/node_modules/zeromq/zeromq.js:79:22)
at [object Object]._flush (/data/nodeload/node_modules/zeromq/zeromq.js:181:21)
at [object Object].send (/data/nodeload/node_modules/zeromq/zeromq.js:160:8)
at Object.incr (/data/nodeload/lib/stats.js:25:17)
I have a hunch it has to do with a stat being incremented before the socket has connected properly. Will do some more digging.
The incr()
function sends data over a PUSH socket every time someone downloads a tarball from GitHub:
exports.incr = (data) ->
if !(data?.repo? and data.commitish?) or data.commitish == data.commit
return
now = new Date
prefix = "stats:nodeload"
key = "#{prefix}:#{now.getFullYear()}:#{now.getMonth()+1}:#{now.getDate()}"
repo = "repo:#{data.repo}"
field = "#{repo}:#{data.commitish}"
data = {}
data[prefix] = count: 1
data[key] = count: 1
data[prefix][repo] = 1
data[key][repo] = 1
data[key][field] = 1
socket.send JSON.stringify(data)
Since PKG_CONFIG_PATH="/usr/local/lib/pkgconfig"
is required on so many OSes (Ubuntu, MacOSX, Cygwin), is there any way to add this path to the wscript
?

I have node 0.4.7 installed from a git clone, and libzmq 2.1.7 verified to work by using other bindings (like Python). The system is Linux Ubuntu 11.04 Server.
Any ideas? Thanks in advance!
Support all the changes in zeromq 3.0. Hopefully it wouldn't take too long.
Thanks
Ollie
Updated to 0.4.0 and get the follow error. I have reinstalled zeromq mulitple times and also rebuilt node-zeromq. Any ideas?

Hi Justin,
Would you be willing to make a pub/sub example?
I've had no luck in getting this to work with the latest zmq and node versions.
Thanks
Seem that I can't set options on send as reported by zmq documentation. Looking at the code seems that all paramenters of the send are treated as message parts, while the last one should be the options for the send.
Can you confirm this? Is a design decision?

Hello,
I've taken the liberty of adding a link to your project's github page to this page: https://github.com/joyent/node/wiki/Modules since when people were asking me where they can find the bindings and I landed up asking them to check the node.js modules page and they came back empty handed. Hope you don't mind. Let me know if you do - I'll remove it.
I have 0MQ 2.1.0 installed, and node.js 3.2, but this node.js binding isn't working for me:
> require('zeromq')
Error: libzmq.so.1: cannot open shared object file: No such file or directory

To be fair, I've gotten a very similar error message when trying to use the Ruby zmq bindings. However, chicken-scheme bindings work fine for me, so I can confirm that 0MQ 2.1.0 itself has definitely installed fine on my system.
Issue with npm install zmq.
libzmq was installed under /usr/local/lib,
/usr/local/lib/pkgconfig/libzmq.pc exists.
PKG_CONFIG_PATH sets to /usr/local/lib/pkgconfig
mac osx 10.5
npm install zeromq also could not find libzmq, but went through and everything worked.

Howdy,
What kind of message per second speed do you normally see with zeromq on nodejs? I was doing some testing with your binding and cannot seem to get above a few hundred per second. Is this what you normally see? I was using publish
see below for my publish server

Hey,
I'm getting an error while connected to a zmq socket, so after a given time I'm getting
Assertion failed: (socket_ == NULL), function ~Socket, file ../zeromq.cc, line 475.
Abort trap
Not sure what's causing it, and the time until I get it varies. I'm unable to catch and treat this exception.
I try to install zmq on windows, however, it reports some error:

do you mind releasing one? are they the same thing? (look to be)
The new hotness is uv_async, not eio_custom. This is future-proof and windows-compatible.
I have a xrep
server which does the bind. When 1 xreq
client connects to the server it works fine. Adding one more crashes the process with this stack trace. Only happens in zmq 2.0.0. Works on zmq 1.0.3.

Hi Justin,
A minor point, but the convention for language bindings is to use the 'zmq' name instead of 'ZeroMQ', to match the library name ('libzmq'). We use 'ZeroMQ' more and more to describe the whole community of projects.
We renamed the library from zeromq to libzmq for this reason. Any chance you can rename the node to zmq.node?
Cheers
Pieter
Hello,
I just wanted to know if the library supports the many-many pattern. Was checking the code (not very familiar with either 0mq or C++ bindings for node.js), but was wondering what Socket._fd would return for a many-many 0mq socket? I mean if the IOWatcher can watch just a single FD, and data can come in on multiple sockets (can it?), how will the events be triggered?
I'd like to use zeromq.node for a project I'm working on, but even the minimal script in the gist below causes node to spin up 100% CPU on two of my boxes I have handy:
Code: http://gist.github.com/581780

Hi Justin, I have a app used zeroMQ module and Socket.Io module.
I want to implement from use input keyword transfer to controller and to zmq.
but in example, scoket.send only just in socket.bind.
I want to run one time the scoket.bind function, and abstract scoket.send function.
But I don't know do that.
For example:
---controller.js(express)
exports.search = function(req, res, next) {
var key = req.params.key;
// send msg to ZMQ (request-reply partten)
-- But When run this, App Error: "TypeError: Socket is busy."
xreply(key);
res.redirect('result/' + service + '/' + encodekey);
};
Do you have this simple example for this?
exports.xreply = function(msg) {
var socketMQ = zeromq.createSocket('xreply');
socketMQ.identity = "server";
socketMQ.bind("tcp://127.0.0.1:5502", function(err) {
if (err)
throw err;
console.log("------zmq server has bound!---------");
socketMQ.on('message', function(envelope, blank, data) {
console
.log("Received: " + envelope + " - "
+ data.toString('utf8'));
});
socketMQ.on('error', function(err) {
console.log("Error: " + err);
});
});
var serviceList = config.service_list;
return function(sendMsg) {
if (msg !== null && msg !== 'undefined') {
// send service list
for ( var index in serviceList) {
this.socketMQ.send(serviceList[index], '' + msg);
}
}
}
};
Thank you very much. Please help me.
I understand if you consider this low prio, especially until the whole procedure around node/npm on windows is settled, but it would be a great way to interop between node and .Net applications.
Segfault at 2.0.8 ZeroMQ and 0.2 NodeJS if run test script (after new zmq.Socket call)
Hi!
it's impossible to npm install this repo unless you have got system wide libzmq-dev installed (debian-ly speaking) or you've root privileges to sudo make install
libzmq from scratch.
While it's easy to override libzmq headers location by running PKG_CONFIG_PATH=/path/of/your/local/libzmq/build/src CXXFLAGS="-I/path/of/your/local/libzmq/build/include" node-waf configure build
, node-waf
seems to not honor passed LINKFLAGS=/path/of/your/local/libzmq/build/src/.libs
to specify custom libraries location, which results in failing by not finding -lzmq
.
Please, consider adding maybe a special target which could download and use libzmq sources locally.
TIA,
--Vladimir
I don't know if this is an issue with the driver, with zeromq or if I'm doing something wrong. Anyway, the pub/sub within an 'inproc' is not working at all, however if I change address to an tcp address it does work, also xrep andrep works perfectly fine with 'inproc'.
var ZMQ = require('zeromq');
var Broadcast = ZMQ.createSocket('pub');
var address = 'inproc://foobar';
Broadcast.bind(address, function(err) {
if (err) {
throw err;
}
var repeater = ZMQ.createSocket('sub');
repeater.connect(address);
repeater.subscribe('');
repeater.on('message', function (message) {
console.log(message.toString());
});
setInterval(function() {
Broadcast.send('foo');
}, 1000);
});
Am I doing something wrong?
Cheers,
We changed ""main": "zeromq"," to ""main": "zmq", on package.json and it worked.
Had no problems on a 32 bit 10.04 box using this tutorial: http://johanharjono.com/archives/633. I can run 'server.js' and get a listener who pulls. Everything installs fine on a 32 bit 10.10 box, but when I run 'node client.js', I get this error:
node: symbol lookup error: /usr/local/lib/node/.npm/zeromq/0.4.0/package/binding.node: undefined symbol: zmq_init

Trace/BPT trap
It would be nice if I could send objects directly across the wire. The JSON.stringify and JSON.parse is pretty slow. Any thoughts here?
There is no error when I call send on a PULL socket, even though this is not allowed (http://api.zeromq.org/2-1-1:zmq-socket#toc13)
The message appears to be buffered by the node code since s.currentSendBacklog()
is incremented.
Would it not make sense to raise error when calling send in this case?
Hi,
I am trying to write a test client and I am getting the following output:
SlowBuffer 59 6f 75 20 61 72 65 20 63 6f 6e 6e 65 63 74 65 64 20 74 6f 20 74 68 65 20 73 6f 63 6b 65 74 20 73 65 72 76 65 72
Here is my client:
var context = require('zeromq'); console.log('Connecting...'); var requester = context.createSocket('req'); requester.on('message', function(response){ console.log('RESPONSE', response); }); requester.on('error', function (response){ console.log('ERROR', response); }); requester.connect("tcp://localhost:5555"); //requester.sendBufferSize = 2408; console.log('[INFO]', requester.sendBufferSize); /* * You must convert the JSON object to a string */ requester.send(new Buffer("Test")); process.on('SIGINT', function() { requester.close() })
Here is my server:
bind('tcp://*:5555'); while (true) { $request = $responder->recv(); $responder->send("You are connected to the socket server"); } ?>
I have a PHP client thats working correctly so I am pretty confident the underlying systems are working properly.
node version = 0.4.9
omq version = 2.1.9
php version = 5.2
Any ideas or suggestions would be appreciated.
Thanks
Steve
I have a strange issue with a pub/sub pattern of mine.
This example works just fine...
https://gist.github.com/4183916c432d4ba32a5a
