Owner

Current status

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 5.1 in Fedora 28 to 5.2 (latest version) in Fedora 29. 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 5.2 will bring new Active Storage framework, Redis Cache Store, HTTP/2 Early Hints, CSP support, opened credentials API. In addition update to Rails 5.2 contains hundreds of other fixes and improvements across all the frameworks.

Scope

  • Proposal owners:
    • The whole Rails stack has to be updated

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 5.2 from upstream

gem install rails -v 5.2.x
rails new app
cd app && rails s

To test only Rails itself

dnf install rubygem-rails
rails new app
cd app && rails s

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

dnf group install 'Ruby on Rails'
rails new app --skip-bundle && cd app
rails s

User Experience

  • New version of Ruby on Rails (5.2) available
  • The most significant Rails 5.2 features:
    • Active Storage
    • Redis Cache Store
    • HTTP/2 Early Hints
    • Credentials
    • Content Security Policy

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)
  • Following gems don't support Rails 5.2 right now and would be broken by the update:
    • (none)
  • As Rails requires Ruby >= 2.2.2, the platform less than the version can not use Rails 5.2.

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
  • Blocks product? No
