Examples: bind to a random port. Connects the socket to a formatted endpoint. Retrieves the value of the given socket option. Receives a frame from the socket. Receives a message from the socket. Sends the given message over the socket; the message is consumed by this call. Example: zsock. Sends one or more strings or binary data objects over the socket. Sends a zero-length message over the socket. Sets the socket identity string.
Sets the given socket option to the given value. Sets the receive high water mark. Sets the receive timeout in milliseconds. Sets the send timeout in milliseconds. Sets the send and receive timeout in milliseconds. Take a look if you like. There are two predefined actions: "send", which sends a specific protocol message, and "terminate", which ends the client connection.
Other actions map to functions in your own code, e. Superstates are a shorthand to reduce the amount of error-prone repetition in a state machine. Here is the same state machine using a superstate:. For example:. If you define an "expired" event anywhere in your dialog, the server will automatically expire idle clients after a timeout, which defaults to 60 seconds.
It's smart to put this into a superstate:. The server timeout can also come from a configuration file, see below. Do not heartbeat from the server to clients; that is fragile. You can call the 'configure' method on the server object to configure it, and you can also call the 'set' method later to change individual configuration options. The generated engine offers zloop integration so you can monitor your own sockets for activity and execute callbacks when messages arrive on them.
Use this API method:. The engine invokes the handler with the 'server' as the argument. Here is the general style of using such a handler. Similarly you can tell the engine to call a 'monitor' function at some specific interval, e. The zproto project lets you generate full asynchronous client stacks in C to talk to the server engines. Overall the model and toolchain is similar to that used for servers.
The main differences is that:. Your input to the code generator is two XML files that defines a set of 'states', and the protocol messages as used to generate the codec. Plus one message for each method defined in the model, including the pre-defined "constructor" and "destructor" methods called after, and before construction and destruction respectively. Names are case insensitive. By convention however we use uppercase for protocol events and methods.
There are two predefined actions: "send", which sends a specific protocol message, and "terminate", which ends the client. The server needs to respond with a PONG. Then, set an expiry timeout of 2 or 3 times the heartbeat interval, and use this to detect a dead server.
As another way to reduce error-prone repetition, it is possible to add actions to be executed for any event that transitions to or from a given state. This is modelled with a before or after element containing one or more action elements inside of a state element.
The given actions will be executed only when the state of the machine changes to or from that state due to an event that has the "next" attribute defined. The expired event will repeat whenever there is no activity from the server, until you set a expiry of zero which ends it. To simplify the delivery of a conventional non-actor API, you can define methods in your state machine.
Here are some examples taken from real projects:. This generates an event in the client state machine, corresponding to the method name. Wait for one of a set of replies from the actor, and store reply properties in the client object. These are defined by one or more tags. All possible replies are defined as objects. The actor's replies are always several frames. The first is the reply name, and the following are the reply fields.
Within your state model you can include another XML file with custom hand-written methods to easily extend the state maschine. To do so include the following:. This section covers some learned experience designing protocols, using zproto and more generally:. A good expiry timeout is perhaps 3 to 10 seconds. The minimum allowed is milliseconds. The client heartbeats the server by sending a PING heartbeat every second if there is no other activity.
The server accepts OPEN in all external states and always treats this as a request to start a new protocol session. This approach resolves stale TCP connections, as well as dead clients and dead servers. It makes the heartbeating interval a client-side decision, and client expiry a server-side decision this seems best in both cases.
Though the Libero documentation is quite old now, it's useful as a guide to what's possible with state machines. The Libero model added superstates, substates, and other useful ways to manage larger state machines. You can find GSL on Github and there's a old backgrounder for the so-called "model oriented programming" we used at iMatix.

Build and test using the usual commands:. Then run these commands: cd src make code check To use zproto as the base for your own projects, create a new project with zproject which nicely integrates with zproto. The Codec Generator Goals of the codec generator: Best performance on high-volume low-complexity data.
Full flexibility on often-changing data headers. Portable to any programming language. Built for ZeroMQ. Easy to use. Add the generated. Don't modify generated codecs. Change the model, and regenerate. The Server Generator While ZeroMQ gives you a powerful communications engine to use in many different ways, building a conventional server is still fairly heavy work.
Quick Background By Pieter Hintjens. The State Machine Model State machines are a little unusual, conceptually. The Libero model is fairly simple and high level, meant to be designed and understood by humans: The machine exists in one of a number of named states. The generated server manages clients automatically. The trace option shows all protocol messages received and sent. Cancels any wakeup alarm on that client. You can also configure other abitrary properties. Server Configuration File You can call the 'configure' method on the server object to configure it, and you can also call the 'set' method later to change individual configuration options.
CZMQ Reactor Integration The generated engine offers zloop integration so you can monitor your own sockets for activity and execute callbacks when messages arrive on them. The zproto Client Model Your input to the code generator is two XML files that defines a set of 'states', and the protocol messages as used to generate the codec. The state machine must handle the "heartbeat" event.
A value of zero means leave the OS default unchanged. The following outlines the different behaviours:. This allows for exponential backoff strategy.

In order to develop and test the library, you'll need the tools required to build from source see above. Socket and context options can be set at runtime, even if they are not implemented by this library. By design, this requires no recompilation if the built version of ZeroMQ has support for them. This allows library users to test and use options that have been introduced in recent versions of ZeroMQ without having to modify this library.
Of course we'd love to include support for new options in an idiomatic way. The test suite will validate and fix the coding style, run all unit tests and verify the validity of the included TypeScript type definitions.
Wait for continuous integration to finish. Prebuilds will be generated for all supported platforms and attached to a Github release. Documentation is automatically generated and committed to gh-pages. Finally, a new NPM package version will be automatically released. Previous versions of ZeroMQ.

If the boost unittest framework is installed, check and installcheck can be run for sanity checking. The CXX prefix should be used on all targets as the compiler version is used in the build path. Building requires a recent version of CMake 2.
You can install chumak from hex. Z is one of the release versions. For more info on rebar3 dependencies see the rebar3 docs. So you need to have ZeroMQ installed, including its development files. The CZMQ library includes experimental classes that are not built by default, but can be built by passing --enable-drafts to configure. Support for these draft classes are being added to goczmq.
To build these features against a CZMQ that has been compiled with --enable-drafts , use go build -tags draft. Note : CZMQ 4. If a prebuilt binary is not available for your platform, installing will attempt to start a build from source. If a prebuilt binary is unavailable or if you want to pass certain options during build, you can build this package from source.
If you want to link against a shared ZeroMQ library, you can build skip downloading libzmq and link with the installed library instead as follows:. You can also get the latest source code from our GitHub repository, but building from the repository will require that you install recent Cython.
For more detail on building pyzmq, see our Wiki. When compiling pyzmq e. If this is not available, pyzmq will try to build libzmq as a Python Extension, though this is not guaranteed to work. If the gem installation complains that it cannot find libzmq or headers, simply pass the location of your libzmq installation to the gem install command:. Users should add this to their Cargo.
As rust-zmq is a wrapper around libzmq , you need a build of libzmq version 4. There are several options available:. This is probably the preferred method when you are running a recent Unix-like OS that has support for pkg-config. For example, on recent Debian-based distributions, you can use the following command to get the prerequiste headers and library installed:.
When building on Windows, using the MSCV toolchain, consider the following when trying to link dynamically against libzmq :. Starting with the upcoming release 0. In your Cargo. When you have a cross-compiled version of libzmq installed, you should be able to cross-compile rust-zmq, assuming a platform supporting pkg-config. Library libzmq czmq.
