 Project Readme

actory

Actor model like, concurrent and distributed framework for Ruby.

Installation

gem install actory

Setup

path_to_actory="/PATH/TO/GEMS/actory-0.0.1"
export PATH=$PATH:$path_to_actory/bin
  • /PATH/TO/GEMS above means the path to the directory of gem files. e.g. $HOME/.rvm/gems/ruby-2.0.0-p247@global/gems

System-wide setup with the root permission

sudo mkdir -p /etc/actory
sudo cp -p $path_to_actory/config/receiver.yml.example /etc/actory
sudo cp -p $path_to_actory/config/sender.yml.example /etc/actory

System-wide setup under the RubyGems

cd $path_to_actory/config
cp receiver.yml.example receiver.yml
cp sender.yml.example sender.yml
sed -i '' "s/\/etc\/actory/\.\.\/\.\.\/\.\.\/config/g" global.yml

Setup inside of each indivisual project

echo "gem actory" >> Gemfile
bundle install --path vendor/bundle
cp ./vendor/bundle
path_to_actory="vendor/bundle/ruby/2.0.0/gems/actory-0.0.1"
cp $path_to_actory/config/receiver.yml.example $path_to_actory/config/receiver.yml
cp $path_to_actory/config/sender.yml.example $path_to_actory/config/sender.yml
sed -i '' "s/\/etc\/actory/\.\.\/\.\.\/\.\.\/config/g" $path_to_actory/config/global.yml

Architecture

  • Actor model like message passing API
  • Dynamically loaded plugins
  • High concurrency
  • Low overheads

System-wide

Sending a message to each receiver to make it deal with the message.

    • timeout
      • Authentication timeout with each receiver.
  • show_progress
    • If it is true, the sender shows you a progress bar.
  • reload_receiver_plugins
    • If it is true, the sender force each receiver reload plugins even in running.
  • log

Usage

Receiver

Foreground

actory-receiver

Background

actory-receiver -d

Sender

require 'actory'
dispacher = Actory::Sender::Dispatcher.new
res = dispatcher.message(METHOD, ARGS)

You can specify an actor or actors with an argument with actors keyword.

require 'actory'
dispacher = Actory::Sender::Dispatcher.new(actors: ["localhost:18800"])
res = dispatcher.message(METHOD, ARGS)
require 'actory'
actors = ["192.168.1.1:18800", "192.168.1.2:18800", "192.168.1.3:18800"]
dispacher = Actory::Sender::Dispatcher.new(actors: actors)
res = dispatcher.message(METHOD, ARGS)

Plugin

You can create your own plugin(s) to be executed by the receiver.

module Actory
module Receiver

class Plugin < Base

  def hello(arg)
    return "Hello #{arg}."
  rescue => e
    msg = Actory::Errors::Generator.new.json(level: "ERROR", message: e.message, backtrace: $@)
    raise StandardError, msg
  end

end

end
end

If you have created a plugin, put it just under the lib/actory/receiver/plugin directory. Then it will be automatically loaded even in the receiver running.

And then, you can call the method from a sender like following:

require 'actory'
dispacher = Actory::Sender::Dispatcher.new
res = dispatcher.message("hello", ["world", "actory"])

The response in an array will be like following:

p res
[{"127.0.0.1:18800"=>["Hello world."]}, {"192.168.1.1:18800"=>["Hello actory."]}]
