MessagePack-RPC over HTTP (JRuby)

This library provides MessagePack-RPC via HTTP as XML-RPC. The original MessagePack-RPC Server in Ruby is not good in some cases. It doesn't scale. It's incompatible with Thread. There is no decent termination processing...

We alreadly have various high perfomance HTTP servers. We can use these in MessagePack-RPC over HTTP.

CAUTION

There is no compatibility with other implementation of normal MessagePack-RPC (not over HTTP). So a normal RPC client can not connect a HTTP server.

PLATFORM NOTIFICATION

This branch is for JRuby, and protocol is comatible with the original gem (msgpack-rpc-over-http) for CRuby. Code is 100% same with msgpack-rpc-over-http by authorNari. See: https://github.com/authorNari/msgpack-rpc-over-http

Usage

Server

confir.ru:

require 'msgpack-rpc-over-http-jruby'
class MyHandler
  def add(x,y) return x+y end
end

run MessagePack::RPCOverHTTP::Server.app(MyHandler.new)

rackup:

% rackup config.ru -s mizuno
Mizuno 0.6.6 (Jetty 8.1.3.v20120416) listening on 0.0.0.0:9292

Client

client.rb:

require 'msgpack-rpc-over-http-jruby'
c = MessagePack::RPCOverHTTP::Client.new("http://0.0.0.0:9292/")
result = c.call(:add, 1, 2)  #=> 3

Extended futures

Support streaming response via Chunked Transfer-Encoding.

# server side
class Handler
  include MessagePack::RPCOverHTTP::Server::Streamer
  def log
    return stream do
      File.open('/var/log/syslog') do |f|
        while line = f.gets.chomp
          # write a chunked data
          chunk(line)
        end
      end
    end
  end
end

# client
client = MessagePack::RPCOverHTTP::Client.new("http://0.0.0.0:80/")
client.stream do |line|
  p line # => "Nov 3 ..."
end
