Current status

• Targeted release: Fedora 25
• Last updated: 2016-06-28
• Tracker bug: #1184910 TODO

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 4.2 in Fedora 24 to 5.0 (latest version) in Fedora 25. 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, update to Rails 5.0 will bring ActionCable (A new framework that seamlessly integrates WebSockets with the rest of your Rails application), API mode (You can create a new Rails application using rails new backend --api), ActionRecord attributes that can override, and exclusive use of rails CLI over Rake.

• Other developers: Update Rails dependent packages to be working with Ruby on Rails 5.0

• Release engineering: Not needed.

• Policies and guidelines: Not needed

• Trademark approval: N/A (not needed for this Change)

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 5.0 from upstream:

gem install rails -v 5.0.x
rails new app
cd app && rails s

• Go to http://127.0.0.1:3000/ and make sure you are running Rails 5.0.x
• To test only Rails itself

dnf install rubygem-{rails,sqlite3}
rails new app
cd app && rails s

• To test the complete feature including generating a new Rails app using RPM

su -c "dnf install rubygem-{rails,sqlite3,coffee-rails,sass-rails,uglifier,jquery-rails,turbolinks,jbuilder,sdoc,spring,byebug,web-console} nodejs"
rails new app --skip-bundle && cd app
rails s

• Go to http://127.0.0.1:3000/ and make sure you are running Rails 5.0.x

User Experience

• New version of Ruby on Rails (5.0) available
• The most significant Rails 5.0 features:
  • ActionCable: user can use WebSockets with the rest of your Rails application.
  • API mode: uesr can create a Rails application for API server easily with API mode.
  • Exclusive use of rails CLI over Rake. Add bin/rails test, bin/rails db:migrate. Now bin/rails is the one master command to rule them all.
  • ActionRecord attributes: user can override ActiveRecord attributes if needed.

Dependencies

• There are several packages, which depends on Ruby on Rails framework. All need to be tested an updated:
• These needs to be surely updated:
  • none now
• openshift-origin-broker and any of rubygem-openshift-origin* gems might need to be updated and tested against Rails 5.0
  • Contact person: Krishna Raman <kraman@redhat.com> from OpenShift Origin team
• Following gems don't support Rails 5.0 right now and would be broken by the update:
  • none now
• As Rails requires Ruby >= 2.2.2, the platform less than the version can not use Rails 5.0.

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 core packages (and their dependencies).
• Contingency deadline: N/A
• Blocks release? No
