  • require_dependency has been documented to be obsolete in :zeitwerk mode. The method is not deprecated as such (yet), but applications are encouraged to not use it.

    In :zeitwerk mode, semantics match Ruby's and you do not need to be defensive with load order. Just refer to classes and modules normally. If the constant name is dynamic, camelize if needed, and constantize.

    Xavier Noria

  • Add 3rd person aliases of Symbol#start_with? and Symbol#end_with?.

    :foo.starts_with?("f") # => true
    :foo.ends_with?("o")   # => true
    

    Ryuta Kamizono

  • Add override of unary plus for ActiveSupport::Duration.

    + 1.second is now identical to +1.second to prevent errors where a seemingly innocent change of formatting leads to a change in the code behavior.

    Before:

    +1.second.class
    # => ActiveSupport::Duration
    (+ 1.second).class
    # => Integer
    

    After:

    +1.second.class
    # => ActiveSupport::Duration
    (+ 1.second).class
    # => ActiveSupport::Duration
    

    Fixes #39079.

    Roman Kushnir

  • Add subsec to ActiveSupport::TimeWithZone#inspect.

    Before:

    Time.at(1498099140).in_time_zone.inspect
    # => "Thu, 22 Jun 2017 02:39:00 UTC +00:00"
    Time.at(1498099140, 123456780, :nsec).in_time_zone.inspect
    # => "Thu, 22 Jun 2017 02:39:00 UTC +00:00"
    Time.at(1498099140 + Rational("1/3")).in_time_zone.inspect
    # => "Thu, 22 Jun 2017 02:39:00 UTC +00:00"
    

    After:

    Time.at(1498099140).in_time_zone.inspect
    # => "Thu, 22 Jun 2017 02:39:00.000000000 UTC +00:00"
    Time.at(1498099140, 123456780, :nsec).in_time_zone.inspect
    # => "Thu, 22 Jun 2017 02:39:00.123456780 UTC +00:00"
    Time.at(1498099140 + Rational("1/3")).in_time_zone.inspect
    # => "Thu, 22 Jun 2017 02:39:00.333333333 UTC +00:00"

  • Calling ActiveSupport::TaggedLogging#tagged without a block now returns a tagged logger.

    logger.tagged("BCX").info("Funky time!") # => [BCX] Funky time!
    

    Eugene Kenny

  • Align Range#cover? extension behavior with Ruby behavior for backwards ranges.

    (1..10).cover?(5..3) now returns false, as it does in plain Ruby.

    Also update #include? and #=== behavior to match.

    Michael Groeneman

  • Update to TZInfo v2.0.0.

    This changes the output of ActiveSupport::TimeZone.utc_to_local, but can be controlled with the ActiveSupport.utc_to_local_returns_utc_offset_times config.

    New Rails 6.1 apps have it enabled by default, existing apps can upgrade via the config in config/initializers/new_framework_defaults_6_1.rb

    See the utc_to_local_returns_utc_offset_times documentation for details.

    Phil Ross, Jared Beck

  • Add Date and Time #yesterday? and #tomorrow? alongside #today?.

    Aliased to #prev_day? and #next_day? to match the existing #prev/next_day methods.

    Jatin Dhankhar

  • Add Enumerable#pick to complement ActiveRecord::Relation#pick.

    Eugene Kenny

  • [Breaking change] ActiveSupport::Callbacks#halted_callback_hook now receive a 2nd argument:

    ActiveSupport::Callbacks#halted_callback_hook now receive the name of the callback being halted as second argument. This change will allow you to differentiate which callbacks halted the chain and act accordingly.

      class Book < ApplicationRecord
        before_save { throw(:abort) }
        before_create { throw(:abort) }
    
        def halted_callback_hook(filter, callback_name)
          Rails.logger.info("Book couldn't be #{callback_name}d")
        end
    
        Book.create # => "Book couldn't be created"
        book.save # => "Book couldn't be saved"
      end

  • Support prepend with ActiveSupport::Concern.

    Allows a module with extend ActiveSupport::Concern to be prepended.

    module Imposter
      extend ActiveSupport::Concern
    
      # Same as `included`, except only run when prepended.
      prepended do
      end
    end
    
    class Person
      prepend Imposter
    end
    

    Class methods are prepended to the base class, concerning is also updated: concerning :Imposter, prepend: true do.

    Jason Karns, Elia Schito

  • Deprecate using Range#include? method to check the inclusion of a value in a date time range. It is recommended to use Range#cover? method instead of Range#include? to check the inclusion of a value in a date time range.

    Vishal Telangre

  • Support added for a round_mode parameter, in all number helpers. (See: BigDecimal::mode.)

    number_to_currency(1234567890.50, precision: 0, round_mode: :half_down) # => "$1,234,567,890"
    number_to_percentage(302.24398923423, precision: 5, round_mode: :down) # => "302.24398%"
    number_to_rounded(389.32314, precision: 0, round_mode: :ceil) # => "390"
    number_to_human_size(483989, precision: 2, round_mode: :up) # => "480 KB"
    number_to_human(489939, precision: 2, round_mode: :floor) # => "480 Thousand"
    
    485000.to_s(:human, precision: 2, round_mode: :half_even) # => "480 Thousand"

  • Array#to_sentence no longer returns a frozen string.

    Before:

    ['one', 'two'].to_sentence.frozen?
    # => true
    

    After:

    ['one', 'two'].to_sentence.frozen?
    # => false

  • When an instance of ActiveSupport::Duration is converted to an iso8601 duration string, if weeks are mixed with date parts, the week part will be converted to days. This keeps the parser and serializer on the same page.

    duration = ActiveSupport::Duration.build(1000000)
    # 1 week, 4 days, 13 hours, 46 minutes, and 40.0 seconds
    
    duration_iso = duration.iso8601
    # P11DT13H46M40S
    
    ActiveSupport::Duration.parse(duration_iso)
    # 11 days, 13 hours, 46 minutes, and 40 seconds
    
    duration = ActiveSupport::Duration.build(604800)
    # 1 week
    
    duration_iso = duration.iso8601
    # P1W
    
    ActiveSupport::Duration.parse(duration_iso)
    # 1 week

  • Add block support to ActiveSupport::Testing::TimeHelpers#travel_back.

    Tim Masliuchenko

  • Update ActiveSupport::Messages::Metadata#fresh? to work for cookies with expiry set when ActiveSupport.parse_json_times = true.

    Christian Gregg

  • Support symbolic links for content_path in ActiveSupport::EncryptedFile.

    Takumi Shotoku

  • Improve Range#===, Range#include?, and Range#cover? to work with beginless (startless) and endless range targets.

    Allen Hsu, Andrew Hodgkinson

  • Don't use Process#clock_gettime(CLOCK_THREAD_CPUTIME_ID) on Solaris.

    Iain Beeston

  • Prevent ActiveSupport::Duration.build(value) from creating instances of ActiveSupport::Duration unless value is of type Numeric.

    Addresses the errant set of behaviours described in #37012 where ActiveSupport::Duration comparisons would fail confusingly or return unexpected results when comparing durations built from instances of String.

    Before:

    small_duration_from_string = ActiveSupport::Duration.build('9')
    large_duration_from_string = ActiveSupport::Duration.build('100000000000000')
    small_duration_from_int = ActiveSupport::Duration.build(9)
    
    large_duration_from_string > small_duration_from_string
    # => false
    
    small_duration_from_string == small_duration_from_int
    # => false
    
    small_duration_from_int < large_duration_from_string
    # => ArgumentError (comparison of ActiveSupport::Duration::Scalar with ActiveSupport::Duration failed)
    
    large_duration_from_string > small_duration_from_int
    # => ArgumentError (comparison of String with ActiveSupport::Duration failed)
    

    After:

    small_duration_from_string = ActiveSupport::Duration.build('9')
    # => TypeError (can't build an ActiveSupport::Duration from a String)
    

    Alexei Emam

  • Add ActiveSupport::Cache::Store#delete_multi method to delete multiple keys from the cache store.

    Peter Zhu

  • Support multiple arguments in HashWithIndifferentAccess for merge and update methods, to follow Ruby 2.6 addition.

    Wojciech Wnętrzak

  • Allow initializing thread_mattr_* attributes via :default option.

    class Scraper
      thread_mattr_reader :client, default: Api::Client.new
    end
    

    Guilherme Mansur

  • Add compact_blank for those times when you want to remove #blank? values from an Enumerable (also compact_blank! on Hash, Array, ActionController::Parameters).

    Dana Sherson

  • Make ActiveSupport::Logger Fiber-safe.

    Use Fiber.current.__id__ in ActiveSupport::Logger#local_level= in order to make log level local to Ruby Fibers in addition to Threads.

    Example:

    logger = ActiveSupport::Logger.new(STDOUT)
    logger.level = 1
    puts "Main is debug? #{logger.debug?}"
    
    Fiber.new {
      logger.local_level = 0
      puts "Thread is debug? #{logger.debug?}"
    }.resume
    
    puts "Main is debug? #{logger.debug?}"
    

    Before:

    Main is debug? false
    Thread is debug? true
    Main is debug? true
    

    After:

    Main is debug? false
    Thread is debug? true
    Main is debug? false
    

    Fixes #36752.

    Alexander Varnin

  • Allow the on_rotation proc used when decrypting/verifying a message to be passed at the constructor level.

    Before:

    crypt = ActiveSupport::MessageEncryptor.new('long_secret')
    crypt.decrypt_and_verify(encrypted_message, on_rotation: proc { ... })
    crypt.decrypt_and_verify(another_encrypted_message, on_rotation: proc { ... })
    

    After:

    crypt = ActiveSupport::MessageEncryptor.new('long_secret', on_rotation: proc { ... })
    crypt.decrypt_and_verify(encrypted_message)
    crypt.decrypt_and_verify(another_encrypted_message)

  • delegate_missing_to would raise a DelegationError if the object delegated to was nil. Now the allow_nil option has been added to enable the user to specify they want nil returned in this case.

    Matthew Tanous

  • truncate would return the original string if it was too short to be truncated and a frozen string if it were long enough to be truncated. Now truncate will consistently return an unfrozen string regardless. This behavior is consistent with gsub and strip.

    Before:

    'foobar'.truncate(5).frozen?
    # => true
    'foobar'.truncate(6).frozen?
    # => false
    

    After:

    'foobar'.truncate(5).frozen?
    # => false
    'foobar'.truncate(6).frozen?
    # => false
