Ruby on Rails 4.0

Summary

Ruby on Rails 4.0 is the latest version of well know web framework written in Ruby.

Owner

Current status

  • Targeted release: Fedora 20
  • Last updated: 2013-07-31
  • Tracker bug: <will be assigned by the Wrangler>

Detailed Description

The Ruby on Rails stack is evolving quickly and Fedora needs to keep pace with it. Therefore the whole Ruby on Rails stack should be updated from 3.2 in Fedora 19 to 4.0 (latest version) in Fedora 20. This will ensure that all the Ruby developers using Fedora have the latest and greatest RPM-packaged Ruby on Rails.

Benefit to Fedora

This update will keep Fedora up-to-date and will ensure that the current Ruby on Rails developers stay with us as they will get support for system-packaged Ruby on Rails of the latest version. Apart from that, Rails 4.0 also bring improved functionality, speed. security and better modularization.

Scope

  • Proposal owners:
  • The whole Rails stack has to be updated
  • New additional gems will have to be packaged
  • Some dependencies of the Rails stack will need update

The packages need to be created/updated (this is probably not an exhaustive list):

  • Other developers: Update Rails dependent packages to be working with Ruby on Rails 4.0
  • Release engineering: Not needed.
  • Policies and guidelines: Not needed

Upgrade/compatibility impact

Web applications build above Ruby on Rails framework might need to be updated. Official upstream upgrade guide might come handy: http://guides.rubyonrails.org/upgrading_ruby_on_rails.html

How To Test

  • No special hardware is needed.
  • To test Rails 4.0 before they actually get into Rawhide, use:
gem install rails
rails new app
cd app && rails s
  • Go to http://127.0.0.1:3000/ and make sure you are running Rails 4.0.x
  • When all packages land in Rawhide, use:
yum install rubygem-{rails,sqlite3}
rails new app
cd app && rails s

User Experience

  • New version of Ruby on Rails (4.0) available

Dependencies

  • There are several packages, which depends on Ruby on Rails framework. All need to be tested an updated.
  • openshift-origin-broker and any of rubygem-openshift-origin* gems might need to be updated and tested against Rails 4.0
    • Contact person: Krishna Raman <kraman@redhat.com> from OpenShift Origin team

Contingency Plan

  • Contingency mechanism: None needed. Rails stack won't be updated until all its dependencies are in Rawhide. After that, it will be a simple matter of updating the 8 core packages (and their dependencies).
  • Contingency deadline: N/A
  • Blocks release? No
