A Go interface to [ZeroMQ](http://www.zeromq.org/) version 4.

|
||
|
|
This requires ZeroMQ version 4.0.1 or above. To use CURVE security in
|
||
|
|
versions prior to 4.2, ZeroMQ must be installed with
|
||
|
|
[libsodium](https://github.com/jedisct1/libsodium) enabled.
|
||
|
|
|
||
|
|
Partial support for ZeroMQ 4.2 DRAFT is available in the alternate
|
||
|
|
version of zmq4 `draft`. The API pertaining to this is subject to
|
||
|
|
change. To use this:
|
||
|
|
|
||
|
|
import (
|
||
|
|
zmq "github.com/pebbe/zmq4/draft"
|
||
|
|
)
|
||
|
|
|
||
|
|
For ZeroMQ version 3, see: http://github.com/pebbe/zmq3
|
||
|
|
|
||
|
|
For ZeroMQ version 2, see: http://github.com/pebbe/zmq2
|
||
|
|
|
||
|
|
Including all examples of [ØMQ - The Guide](http://zguide.zeromq.org/page:all).

## API change
|
||
|
|
|

|

There has been an API change in commit
|
||
|
|

|
|
in the functions `AuthAllow` and `AuthDeny`.
|
||
|
|
|
||
|
|
Old:
|
||
|
|
|
||
|
|
func AuthAllow(addresses ...string)
|
||
|
|
func AuthDeny(addresses ...string)
|
||
|
|
|
||
|
|
New:
|
||
|
|
|
||
|
|
func AuthAllow(domain string, addresses ...string)
|
||
|
|
func AuthDeny(domain string, addresses ...string)
|
||
|
|
|
||
|
|
If `domain` can be parsed as an IP address, it will be interpreted as
|
||
|
|
such, and it and all remaining addresses are added to all domains.
|
||
|
|
|
||
|
|
So this should still work as before:
|
||
|
|
|
||
|
|
zmq.AuthAllow("127.0.0.1", "123.123.123.123")
|
||
|
|
|
||
|
|
But this won't compile:
|
||
|
|
|
||
|
|
a := []string{"127.0.0.1", "123.123.123.123"}
|
||
|
|
zmq.AuthAllow(a...)
|
||
|
|
|
||
|
|
And needs to be rewritten as:
|
||
|
|
|
||
|
|
a := []string{"127.0.0.1", "123.123.123.123"}
|
||
|
|
zmq.AuthAllow("*", a...)
|
||
|
|
|
||
|
|
Furthermore, an address can now be a single IP address, as well as an IP
|
||
|
|
address and mask in CIDR notation, e.g. "123.123.123.0/24".
