Redrack::Session 1.0.0 and Redrails::Session 1.0.0

Hello, not sure what the convention(s)/requirement(s) are for posting
release annoucements but I’m going to just hold my breath here and click
“send” anyway… (hope no one is too offended).

The redrack-session gem is a redis-based session store for rack
applications while redrails-session is a simple “glue” or wrapper gem to
make it super-simple to use redrack-session in your rails apps.

Like others who’ve created similar gems, this is pretty much a
“translation” of the Memcached session store that comes with the rack
(Rack::Session::Memcached). This is a fresh, brand new gem and I’d love
get some feedback.

This gem requires a redis server, the redis gem (~> 2.2.2), and the
redis-namespace gem (~> 1.1.0). It’s a given that rack is required (~>
1.3.5). This gem is based on the latest 1.3.x version of rack and does
support the older 1.2.x version(s) of rack.

The redrails-session gem requires rails (~> 3.1.0) and the
gem (~> 1.0.0).

== redrack-session: (gem
install redrack-session)
== redrails-session: (gem
install redrails-session)

Example usage of redrack-session:

require ‘rack’
require ‘redrack-session’

class MyApp
def call(env)
session = env[“rack.session”]
session[“counter”] ||= 0
session[“counter”] += 1
[200, {“Content-Type” => “text/plain”}, [“Counter:

:app =>,
:Port => 9292

Example usage of redrails-session:


source :rubygems
gem “rails”, “3.1.1”
gem “redrails-session”, “~> 1.0.0”

… other gems …


require ‘redrails-store’
MyApp::Application.config.session_store :redrails_session_store

== Future Improvements

I plan to add clustering support to the redrack-session gem (using
Redis::HashRing?). I’d also like to make it so the redrails-session gem
can, by default, look for a ‘config/redrails-session.yml’ (or similar)
configuration file in a rails project in order to load
configuration settings. I may play with adding a railtie initializer to
redrails-session to support zero-configuration when using defaults,
obviating the need for ‘config/initializers/session_store.rb’.

Anyhow, I know there are already solutions out there but none quite met
demanding requirements of my personal OCD requirements. Plus, it’s been
fun learning opportunity. Hopefully others will find this useful too.
