Rails on Rack Rails guide: indicate that Metal pieces now require an "X-Cascade" header with a value of "pass" to continue the Metal chain execution instead of a HTTP 404 response. Also removed reference to old code.

In the event a migration already exists with that number, the new migration's timestamp will be incremented by 1.

Make i18n fallbacks configurable and fallback to the default locale by default in production [#4428 state:resolved]

Allows to configure locale fallbacks through config.i18n.fallbacks. The default setting
config.i18n.fallbacks = true in production.rb will make I18n.t lookup fallback to the
I18n.default_locale if a translation could not be found for the current or given locale.

config.fallbacks = true

config.fallbacks.map = { :ca => :es }
config.fallbacks.defaults = [:'es-ES', :es]

config.fallbacks = [:'es-ES', :es]

config.fallbacks = { :ca => :es }

config.fallbacks = [:'es-ES', :es, { :ca => :es }]

They can be bundled. Just the git repos can't. Use rails/rack-mount for that.

This reverts commit ef6cdc97.

Instead of using a single `notify_observers` call for every callback type,
each observer now registers a unique callback for itself. Example:

  before_save :_notify_user_observer_for_before_save

  def _notify_user_observer_for_before_save
    observer.update(:before_save, self)
  end

Benefit: "before" callbacks halt when `observer.update` returns false.
This way, ActiveRecord observers can prevent records from saving.

`Observable#notify_observers` from Ruby always returns false (which halts ActiveRecord
callback chains) and has extra features (like `changed`) that were never used.

Benefits: test able to run independently, subclassing instead of changing the original Comment model
