rails/activesupport/CHANGELOG.md

• Allow Range#=== and Range#cover? on Range

  Range#cover? can now accept a range argument like Range#include? and Range#===. Range#=== works correctly on Ruby 2.6. Range#include? is moved into a new file, with these two methods.

  Requiring active_support/core_ext/range/include_range is now deprecated. Use require "active_support/core_ext/range/compare_range" instead.

• Add index_with to Enumerable.

  Allows creating a hash from an enumerable with the value from a passed block or a default argument.

  %i( title body ).index_with { |attr| post.public_send(attr) }
  # => { title: "hey", body: "what's up?" }
  
  %i( title body ).index_with(nil)
  # => { title: nil, body: nil }
  

  Closely linked with index_by, which creates a hash where the keys are extracted from a block.

• Fix bug where ActiveSupport::Timezone.all would fail when tzinfo data for any timezone defined in ActiveSupport::TimeZone::MAPPING is missing.

  Dominik Sander

• Redis cache store: delete_matched no longer blocks the Redis server. (Switches from evaled Lua to a batched SCAN + DEL loop.)

  Gleb Mazovetskiy

• Fix bug where ActiveSupport::Cache will massively inflate the storage size when compression is enabled (which is true by default). This patch does not attempt to repair existing data: please manually flush the cache to clear out the problematic entries.

  Godfrey Chan

• Fix bug where URI.unscape would fail with mixed Unicode/escaped character input:

  URI.unescape("\xe3\x83\x90")  # => "バ"
  URI.unescape("%E3%83%90")  # => "バ"
  URI.unescape("\xe3\x83\x90%E3%83%90")  # => Encoding::CompatibilityError

• Add before? and after? methods to Date, DateTime, Time, and TimeWithZone.

• ActiveSupport::Inflector#ordinal and ActiveSupport::Inflector#ordinalize now support translations through I18n.

  # locale/fr.rb
  
  {
    fr: {
      number: {
        nth: {
          ordinals: lambda do |_key, number:, **_options|
            if number.to_i.abs == 1
              'er'
            else
              'e'
            end
          end,
  
          ordinalized: lambda do |_key, number:, **_options|
            "#{number}#{ActiveSupport::Inflector.ordinal(number)}"
          end
        }
      }
    }
  }

• Add :private option to ActiveSupport's Module#delegate in order to delegate methods as private:

  class User < ActiveRecord::Base
    has_one :profile
    delegate :date_of_birth, to: :profile, private: true
  
    def age
      Date.today.year - date_of_birth.year
    end
  end
  
  # User.new.age  # => 29
  # User.new.date_of_birth
  # => NoMethodError: private method `date_of_birth' called for #<User:0x00000008221340>
  

  Tomas Valent

• String#truncate_bytes to truncate a string to a maximum bytesize without breaking multibyte characters or grapheme clusters like 👩‍👩‍👦‍👦.

  Jeremy Daer

• String#strip_heredoc preserves frozenness.

  "foo".freeze.strip_heredoc.frozen?  # => true
  

  Fixes that frozen string literals would inadvertently become unfrozen:

  # frozen_string_literal: true
  
  foo = <<-MSG.strip_heredoc
    la la la
  MSG
  
  foo.frozen?  # => false !??

• Rails 6 requires Ruby 2.4.1 or newer.
