  • Update String#camelize to provide feedback when wrong option is passed

    String#camelize was returning nil without any feedback when an invalid option was passed as a parameter.

    Previously:

    'one_two'.camelize(true)
    => nil
    

    Now:

    'one_two'.camelize(true)
    => ArgumentError: Invalid option, use either :upper or :lower.

  • Fix modulo operations involving durations

    Rails 5.1 introduced ActiveSupport::Duration::Scalar as a wrapper around numeric values as a way of ensuring a duration was the outcome of an expression. However, the implementation was missing support for modulo operations. This support has now been added and should result in a duration being returned from expressions involving modulo operations.

    Prior to Rails 5.1:

    5.minutes % 2.minutes
    => 60
    

    Now:

    5.minutes % 2.minutes
    => 1 minute
    

    Fixes #29603 and #29743.

  • Fix division where a duration is the denominator

    PR #29163 introduced a change in behavior when a duration was the denominator in a calculation - this was incorrect as dividing by a duration should always return a Numeric. The behavior of previous versions of Rails has been restored.

    Fixes #29592.

  • Add purpose and expiry support to ActiveSupport::MessageVerifier & ActiveSupport::MessageEncryptor.

    For instance, to ensure a message is only usable for one intended purpose:

    token = @verifier.generate("x", purpose: :shipping)
    
    @verifier.verified(token, purpose: :shipping) # => "x"
    @verifier.verified(token)                     # => nil
    

    Or make it expire after a set time:

    @verifier.generate("x", expires_in: 1.month)
    @verifier.generate("y", expires_at: Time.now.end_of_year)
    

    Showcased with ActiveSupport::MessageVerifier, but works the same for ActiveSupport::MessageEncryptor's encrypt_and_sign and decrypt_and_verify.

  • Make the order of Hash#reverse_merge! consistent with HashWithIndifferentAccess.

  • Add freeze_time helper which freezes time to Time.now in tests.

  • Default ActiveSupport::MessageEncryptor to use AES 256 GCM encryption.

    On for new Rails 5.2 apps. Upgrading apps can find the config as a new framework default.

  • Cache: write_multi

    Rails.cache.write_multi foo: 'bar', baz: 'qux'
    

    Plus faster fetch_multi with stores that implement write_multi_entries. Keys that aren't found may be written to the cache store in one shot instead of separate writes.

    The default implementation simply calls write_entry for each entry. Stores may override if they're capable of one-shot bulk writes, like Redis MSET.

  • Add default option to module and class attribute accessors.

    mattr_accessor :settings, default: {}
    

    Works for mattr_reader, mattr_writer, cattr_accessor, cattr_reader, and cattr_writer as well.

  • Add Date#prev_occurring and Date#next_occurring to return specified next/previous occurring day of week.

  • Add default option to class_attribute.

    Before:

    class_attribute :settings
    self.settings = {}
    

    Now:

    class_attribute :settings, default: {}

  • #singularize and #pluralize now respect uncountables for the specified locale.

  • Add ActiveSupport::CurrentAttributes to provide a thread-isolated attributes singleton. Primary use case is keeping all the per-request attributes easily available to the whole system.

  • Fix implicit coercion calculations with scalars and durations

    Previously, calculations where the scalar is first would be converted to a duration of seconds, but this causes issues with dates being converted to times, e.g:

    Time.zone = "Beijing"           # => Asia/Shanghai
    date = Date.civil(2017, 5, 20)  # => Mon, 20 May 2017
    2 * 1.day                       # => 172800 seconds
    date + 2 * 1.day                # => Mon, 22 May 2017 00:00:00 CST +08:00
    

    Now, the ActiveSupport::Duration::Scalar calculation methods will try to maintain the part structure of the duration where possible, e.g:

    Time.zone = "Beijing"           # => Asia/Shanghai
    date = Date.civil(2017, 5, 20)  # => Mon, 20 May 2017
    2 * 1.day                       # => 2 days
    date + 2 * 1.day                # => Mon, 22 May 2017
    

    Fixes #29160, #28970.

  • Add support for versioned cache entries. This enables the cache stores to recycle cache keys, greatly saving on storage in cases with frequent churn. Works together with the separation of #cache_key and #cache_version in Active Record and its use in Action Pack's fragment caching.

    DHH

  • Pass gem name and deprecation horizon to deprecation notifications.

    Willem van Bergen

  • Add support for :offset and :zone to ActiveSupport::TimeWithZone#change

    Andrew White

  • Add support for :offset to Time#change

    Fixes #28723.

  • Add fetch_values for HashWithIndifferentAccess

    The method was originally added to Hash in Ruby 2.3.0.
