Sending mail asynchronously in Rails using Workling

Sending mail asynchronously in Rails using Workling

If you want to send mail asynchronously in your rails app, but don’t want to bother with using a queue server like Starling, then have a go at this…

First, run this:

./script/plugin install git://github.com/purzelrakete/workling.git
./script/plugin install git://github.com/langalex/workling_mailer.git
./script/plugin install git://github.com/matthewrudy/rudeq.git
rake queue:setup
rake db:migrate

    rake queue:setup

    now add this to your environment: 

    Workling::Clients::MemcacheQueueClient.memcache_client_class = RudeQ::Client
    Workling::Remote.dispatcher = Workling::Remote::Runners::ClientRunner.new

    Finally, add this into the body of your mailer classes:

    include AsynchMail

    now start the workling client: 

    ./script/workling_client start

    done!

Description: A rails DB-based queue plugin

async rails ruby starling rudeq

  • RudeQ
    =============
    A simple DB based queue,
    designed for situations where a server based queue is unnecessary.

Simple AMQP Library for Ruby

    • AMQP model does have some nice benefits:



      • It is designed for highly scalable deployment scenarios, so it will give you room to grow without having to re-architect your software;
      • It defines a language-neutral wire format, so you can use it to integrate with other languages;
      • It incorporates a robust and generalized message routing infrastructure.

  • It's been around for a while now, but Starling is a "light-weight persistent queue server that speaks the MemCache protocol." Starling makes it ridiculously easy to set up a network-accessible queue (or many queues) for, say, asynchronous job processing between multiple processes and machines. It was developed by Twitter to handle the heavy amount of queueing necessary to keep their service ticking over.
  • FiveRuns have even created their own fork that, they say, is significantly faster.

ruby rails workflow engine

  • Ruote is a workflow engine written in Ruby. It’s a runtime for long running [business] processes.

  • There is a small quickstart available, it focuses on the ruote ‘gem’. For an example integration in Rails there is an online demo (though it’s still running an old version)




    Processes are explicitely defined and may be explicitely handled (start, pause, cancel, update).




    A process is started by handing a [business] process definition to the engine. A process definition is expressed in ruote’s own process definition language, which comes in two flavours : XML and a Ruby DSL.




    A process definition will describe the flow of work among participants.




    A ruote engine can handle simultaneously multiple process instances, created from one or more different process definitions. A process instance can be modified on the fly.

SIP Servlets - SIp vs Jain

JRuby/Rails Integration with Torquebox Telco Framework

www.mobicents.org/...index.html - Preview

jruby ruby rails tips voip jain sip telco

  • Mobicents Sip Servlets is compatible with the Torquebox Telco Framework JRuby on Rails integration. The framework allows you to create powerful, pure or converged VoIP JRuby on Rails applications.


    JRuby features a powerful and well deployed scripting language that allows you to modify your application at runtime (this is true even for the SIP and Media part that Mobicents Sip Servlets offer) without restarting the server. In addition, TorqueBox is a new kind of Ruby application platform that integrates popular technologies such as Ruby-on-Rails, while extending the footprint of Ruby applications to include support for Job Scheduling, Task Queues, SOAP Handling, and other capabilities.


    To obtain more information about building pure JRuby-Rails applications that leverage Mobicents SIP Servlets SIP and mediat capabilities, refer to the Torquebox User Documentation.


    Check this blog post to help you create your first pure Torquebox JRuby Telco application and our pure JRuby on Rails TorqueBox Telco example showcasing this integration.

  • Sip Servlets

    JAIN SLEE

    Application Architecture

    Based on HTTP Servlets. Unit of logic is the SIP Servlets

    Component based, Object Orientated architecture. Unit of logic is the Service Building Block

    Composition through Application Router

    Composition through parent-child relationship

    Application State

    Servlets are stateless

    SBBs may be stateful.

    Shared state stored in a session and visible to all Servlets with access to the session

    SBB state is transacted and a property of the SBB itself. Shared state may be stored in a separate ActivityContext via a type safe interface

    Concurrency Control

    Application managed : use of Java monitors

    System Managed : isolation of concurrent transactions

    Facilities (Utilities for Applications)

    Timer, Listeners

    Timer, Trace, Alarm, Statistics, Profiles.

    Protocol Support

    SIP and HTTP

    Protocol agnostic. Consistent event model, regardless of protocol/resource

    Availability Mechanisms

    Container managed state (session object) that can be replicated

    Container managed state (SBB CMP, Facility, ActivityContext) that can be replicated

    No transaction context for SIP message processing

    Transaction context for event delivery

    Non transacted state operations

    Container managed state operations are transacted

    Facilities are non transacted

    Facilities, timers, are transacted

    No defined failure model

    Well defined and understood failure model via transactions

    Management

    No standard management mechanisms defined

    JMX Interface for managing applications, life cycle, upgrades, ...

Deploying a Rails app without a database using Capistrano

So you’ve got a simple-but-devastatingly-clever Rails app that doesn’t use a database, you’ve dutifully added the line to config/environment.rb to disable the ActiveRecord framework, and now you’re ready to unleash it to the world, using Capistrano for deployment. But when you run ‘cap deploy:cold’, it merrily tries to run database migrations and fails with “uninitialized constant ActiveRecord”. How do you make Capistrano behave?

A simple question, with a simple answer, but one which is curiously absent from the internet. Googlejuice ahoy!

Stick this at the bottom of config/deploy.rb:

namespace :deploy do
desc "Override deploy:cold to NOT run migrations - there's no database"
task :cold do
update
start
end
end
