Overview

An implementation of the Stomp protocol for Ruby. See:

• [STOMP 1.0, 1.1, and 1.2] (http://stomp.github.com/index.html)

Hash Login Example Usage (this is the recommended login technique):

    hash = {
        :hosts => [
        # First connect is to remotehost1
        {:login => "login1", :passcode => "passcode1", :host => "remotehost1", :port => 61612, :ssl => true},
        # First failover connect is to remotehost2
        {:login => "login2", :passcode => "passcode2", :host => "remotehost2", :port => 61613, :ssl => false},
        ],
        # These are the default parameters and do not need to be set
        :reliable => true,                  # reliable (use failover)
        :initial_reconnect_delay => 0.01,   # initial delay before reconnect (secs)
        :max_reconnect_delay => 30.0,       # max delay before reconnect
        :use_exponential_back_off => true,  # increase delay between reconnect attpempts
        :back_off_multiplier => 2,          # next delay multiplier
        :max_reconnect_attempts => 0,       # retry forever, use # for maximum attempts
        :randomize => false,                # do not radomize hosts hash before reconnect
        :connect_timeout => 0,              # Timeout for TCP/TLS connects, use # for max seconds
        :connect_headers => {},             # user supplied CONNECT headers (req'd for Stomp 1.1+)
        :parse_timeout => 5,                # IO::select wait time on socket reads
        :logger => nil,                     # user suplied callback logger instance
        :dmh => false,                      # do not support multihomed IPV4 / IPV6 hosts during failover
        :closed_check => true,              # check first if closed in each protocol method
        :hbser => false,                    # raise on heartbeat send exception
        :stompconn => false,                # Use STOMP instead of CONNECT
        :usecrlf => false,                  # Use CRLF command and header line ends (1.2+)
        :max_hbread_fails => 0,             # Max HB read fails before retry.  0 => never retry
        :max_hbrlck_fails => 0,             # Max HB read lock obtain fails before retry.  0 => never retry
        :fast_hbs_adjust => 0.0,            # Fast heartbeat senders sleep adjustment, seconds, needed ...
                                            # For fast heartbeat senders.  'fast' == YMMV.  If not
                                            # correct for your environment, expect unnecessary fail overs
        :connread_timeout => 0,             # Timeout during CONNECT for read of CONNECTED/ERROR, secs
        :tcp_nodelay => true,               # Turns on the TCP_NODELAY socket option; disables Nagle's algorithm
        :start_timeout => 0,                # Timeout around Stomp::Client initialization
        :sslctx_newparm => nil,             # Param for SSLContext.new
        :ssl_post_conn_check => true,       # Further verify broker identity
      }

      # for a client
      client = Stomp::Client.new(hash)

      # for a connection
      connection = Stomp::Connection.new(hash)

Positional Parameter Usage:

    client = Stomp::Client.new("user", "pass", "localhost", 61613)
    client.publish("/queue/mine", "hello world!")
    client.subscribe("/queue/mine") do |msg|
        p msg
    end

Stomp URL Usage:

A Stomp URL must begin with 'stomp://' and can be in one of the following forms:

    stomp://host:port
    stomp://host.domain.tld:port
    stomp://login:passcode@host:port
    stomp://login:[email protected]:port
    
    # e.g. c = Stomp::Client.new(urlstring)

Failover + SSL Example URL Usage:

    options = "initialReconnectDelay=5000&randomize=false&useExponentialBackOff=false"
    # remotehost1 uses SSL, remotehost2 doesn't
    client = Stomp::Client.new("failover:(stomp+ssl://login1:passcode1@remotehost1:61612,stomp://login2:passcode2@remotehost2:61613)?#{options}")
    client.publish("/queue/mine", "hello world!")
    client.subscribe("/queue/mine") do |msg|
        p msg
    end
