MessagePack-RPC over HTTP (Ruby)

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.

Usage

Server

confir.ru:

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

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

rackup:

% rackup config.ru -s thin
>> Thin web server (v1.5.0 codename Knife)
>> Maximum connections set to 1024
>> Listening on 0.0.0.0:9292, CTRL+C to stop

Client

client.rb:

require 'msgpack-rpc-over-http'
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
