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

• 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)

• 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

• 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. Fixes #36752.

  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
  p "Main is debug? #{logger.debug?}"
  
  Fiber.new {
    logger.local_level = 0
    p "Thread is debug? #{logger.debug?}"
  }.resume
  
  p "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

• 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
