## Rails 4.2.4 (August 24, 2015) ## * Fix a `SystemStackError` when encoding an `Enumerable` with `json` gem and with the Active Support JSON encoder loaded. Fixes #20775. *Sammy Larbi*, *Prathamesh Sonpatki* * Fix not calling `#default` on `HashWithIndifferentAcess#to_hash` when only `default_proc` is set, which could raise. *Simon Eskildsen* * Fix setting `default_proc` on `HashWithIndifferentAccess#dup` *Simon Eskildsen* ## Rails 4.2.3 (June 25, 2015) ## * Fix a range of values for parameters of the Time#change *Nikolay Kondratyev* * Add some missing `require 'active_support/deprecation'` *Akira Matsuda* ## Rails 4.2.2 (June 16, 2015) ## * Fix XSS vulnerability in `ActiveSupport::JSON.encode` method. CVE-2015-3226. *Rafael Mendonça França* * Fix denial of service vulnerability in the XML processing. CVE-2015-3227. *Aaron Patterson* ## Rails 4.2.1 (March 19, 2015) ## * Fixed a problem where String#truncate_words would get stuck with a complex string. *Henrik Nygren* * Fixed a roundtrip problem with AS::SafeBuffer where primitive-like strings will be dumped as primitives: Before: YAML.load ActiveSupport::SafeBuffer.new("Hello").to_yaml # => "Hello" YAML.load ActiveSupport::SafeBuffer.new("true").to_yaml # => true YAML.load ActiveSupport::SafeBuffer.new("false").to_yaml # => false YAML.load ActiveSupport::SafeBuffer.new("1").to_yaml # => 1 YAML.load ActiveSupport::SafeBuffer.new("1.1").to_yaml # => 1.1 After: YAML.load ActiveSupport::SafeBuffer.new("Hello").to_yaml # => "Hello" YAML.load ActiveSupport::SafeBuffer.new("true").to_yaml # => "true" YAML.load ActiveSupport::SafeBuffer.new("false").to_yaml # => "false" YAML.load ActiveSupport::SafeBuffer.new("1").to_yaml # => "1" YAML.load ActiveSupport::SafeBuffer.new("1.1").to_yaml # => "1.1" *Godfrey Chan* * Replace fixed `:en` with `I18n.default_locale` in `Duration#inspect`. *Dominik Masur* * Add missing time zone definitions for Russian Federation and sync them with `zone.tab` file from tzdata version 2014j (latest). *Andrey Novikov* ## Rails 4.2.0 (December 20, 2014) ## * The decorated `load` and `require` methods are now kept private. Fixes #17553. *Xavier Noria* * `String#remove` and `String#remove!` accept multiple arguments. *Pavel Pravosud* * `TimeWithZone#strftime` now delegates every directive to `Time#strftime` except for '%Z', it also now correctly handles escaped '%' characters placed just before time zone related directives. *Pablo Herrero* * Corrected `Inflector#underscore` handling of multiple successive acroynms. *James Le Cuirot* * Delegation now works with ruby reserved words passed to `:to` option. Fixes #16956. *Agis Anastasopoulos* * Added method `#eql?` to `ActiveSupport::Duration`, in addition to `#==`. Currently, the following returns `false`, contrary to expectation: 1.minute.eql?(1.minute) Adding method `#eql?` will make this behave like expected. Method `#eql?` is just a bit stricter than `#==`, as it checks whether the argument is also a duration. Their parts may be different though. 1.minute.eql?(60.seconds) # => true 1.minute.eql?(60) # => false *Joost Lubach* * `Time#change` can now change nanoseconds (`:nsec`) as a higher-precision alternative to microseconds (`:usec`). *Agis Anastasooulos* * `MessageVerifier.new` raises an appropriate exception if the secret is `nil`. This prevents `MessageVerifier#generate` from raising a cryptic error later on. *Kostiantyn Kahanskyi* * Introduced new configuration option `active_support.test_order` for specifying the order in which test cases are executed. This option currently defaults to `:sorted` but will be changed to `:random` in Rails 5.0. *Akira Matsuda*, *Godfrey Chan* * Fixed a bug in `Inflector#underscore` where acroynms in nested constant names are incorrectly parsed as camelCase. Fixes #8015. *Fred Wu*, *Matthew Draper* * Make `Time#change` throw an exception if the `:usec` option is out of range and the time has an offset other than UTC or local. *Agis Anastasopoulos* * `Method` objects now report themselves as not `duplicable?`. This allows hashes and arrays containing `Method` objects to be `deep_dup`ed. *Peter Jaros* * `determine_constant_from_test_name` does no longer shadow `NameError`s which happens during constant autoloading. Fixes #9933. *Guo Xiang Tan* * Added instance_eval version to Object#try and Object#try!, so you can do this: person.try { name.first } instead of: person.try { |person| person.name.first } *DHH*, *Ari Pollak* * Fix the `ActiveSupport::Duration#instance_of?` method to return the right value with the class itself since it was previously delegated to the internal value. *Robin Dupret* * Fix rounding errors with `#travel_to` by resetting the usec on any passed time to zero, so we only travel with per-second precision, not anything deeper than that. *DHH* * Fix DateTime comparison with `DateTime::Infinity` object. *Rafael Mendonça França* * Added Object#itself which returns the object itself. Useful when dealing with a chaining scenario, like Active Record scopes: Event.public_send(state.presence_in([ :trashed, :drafted ]) || :itself).order(:created_at) *DHH* * `Object#with_options` executes block in merging option context when explicit receiver in not passed. *Pavel Pravosud* * Fixed a compatibility issue with the `Oj` gem when cherry-picking the file `active_support/core_ext/object/json` without requiring `active_support/json`. Fixes #16131. *Godfrey Chan* * Make `Hash#with_indifferent_access` copy the default proc too. *arthurnn*, *Xanders* * Add `String#truncate_words` to truncate a string by a number of words. *Mohamed Osama* * Deprecate `capture` and `quietly`. These methods are not thread safe and may cause issues when used in threaded environments. To avoid problems we are deprecating them. *Tom Meier* * `DateTime#to_f` now preserves the fractional seconds instead of always rounding to `.0`. Fixes #15994. *John Paul Ashenfelter* * Add `Hash#transform_values` to simplify a common pattern where the values of a hash must change, but the keys are left the same. *Sean Griffin* * Always instrument `ActiveSupport::Cache`. Since `ActiveSupport::Notifications` only instruments items when there are attached subscribers, we don't need to disable instrumentation. *Peter Wagenet* * Make the `apply_inflections` method case-insensitive when checking whether a word is uncountable or not. *Robin Dupret* * Make Dependencies pass a name to NameError error. *arthurnn* * Fixed `ActiveSupport::Cache::FileStore` exploding with long paths. *Adam Panzer*, *Michael Grosser* * Fixed `ActiveSupport::TimeWithZone#-` so precision is not unnecessarily lost when working with objects with a nanosecond component. `ActiveSupport::TimeWithZone#-` should return the same result as if we were using `Time#-`: Time.now.end_of_day - Time.now.beginning_of_day # => 86399.999999999 Before: Time.zone.now.end_of_day.nsec # => 999999999 Time.zone.now.end_of_day - Time.zone.now.beginning_of_day # => 86400.0 After: Time.zone.now.end_of_day - Time.zone.now.beginning_of_day # => 86399.999999999 *Gordon Chan* * Fixed precision error in NumberHelper when using Rationals. Before: ActiveSupport::NumberHelper.number_to_rounded Rational(1000, 3), precision: 2 # => "330.00" After: ActiveSupport::NumberHelper.number_to_rounded Rational(1000, 3), precision: 2 # => "333.33" See #15379. *Juanjo Bazán* * Removed deprecated `Numeric#ago` and friends Replacements: 5.ago => 5.seconds.ago 5.until => 5.seconds.until 5.since => 5.seconds.since 5.from_now => 5.seconds.from_now See #12389 for the history and rationale behind this. *Godfrey Chan* * DateTime `advance` now supports partial days. Before: DateTime.now.advance(days: 1, hours: 12) After: DateTime.now.advance(days: 1.5) Fixes #12005. *Shay Davidson* * `Hash#deep_transform_keys` and `Hash#deep_transform_keys!` now transform hashes in nested arrays. This change also applies to `Hash#deep_stringify_keys`, `Hash#deep_stringify_keys!`, `Hash#deep_symbolize_keys` and `Hash#deep_symbolize_keys!`. *OZAWA Sakuro* * Fixed confusing `DelegationError` in `Module#delegate`. See #15186. *Vladimir Yarotsky* * Fixed `ActiveSupport::Subscriber` so that no duplicate subscriber is created when a subscriber method is redefined. *Dennis Schön* * Remove deprecated string based terminators for `ActiveSupport::Callbacks`. *Eileen M. Uchitelle* * Fixed an issue when using `ActiveSupport::NumberHelper::NumberToDelimitedConverter` to convert a value that is an `ActiveSupport::SafeBuffer` introduced in 2da9d67. See #15064. *Mark J. Titorenko* * `TimeZone#parse` defaults the day of the month to '1' if any other date components are specified. This is more consistent with the behavior of `Time#parse`. *Ulysse Carion* * `humanize` strips leading underscores, if any. Before: '_id'.humanize # => "" After: '_id'.humanize # => "Id" *Xavier Noria* * Fixed backward compatibility issues introduced in 326e652. Empty Hash or Array should not be present in serialization result. {a: []}.to_query # => "" {a: {}}.to_query # => "" For more info see #14948. *Bogdan Gusiev* * Add `Digest::UUID::uuid_v3` and `Digest::UUID::uuid_v5` to support stable UUID fixtures on PostgreSQL. *Roderick van Domburg* * Fixed `ActiveSupport::Duration#eql?` so that `1.second.eql?(1.second)` is true. This fixes the current situation of: 1.second.eql?(1.second) # => false `eql?` also requires that the other object is an `ActiveSupport::Duration`. This requirement makes `ActiveSupport::Duration`'s behavior consistent with the behavior of Ruby's numeric types: 1.eql?(1.0) # => false 1.0.eql?(1) # => false 1.second.eql?(1) # => false (was true) 1.eql?(1.second) # => false { 1 => "foo", 1.0 => "bar" } # => { 1 => "foo", 1.0 => "bar" } { 1 => "foo", 1.second => "bar" } # now => { 1 => "foo", 1.second => "bar" } # was => { 1 => "bar" } And though the behavior of these hasn't changed, for reference: 1 == 1.0 # => true 1.0 == 1 # => true 1 == 1.second # => true 1.second == 1 # => true *Emily Dobervich* * `ActiveSupport::SafeBuffer#prepend` acts like `String#prepend` and modifies instance in-place, returning self. `ActiveSupport::SafeBuffer#prepend!` is deprecated. *Pavel Pravosud* * `HashWithIndifferentAccess` better respects `#to_hash` on objects it receives. In particular, `.new`, `#update`, `#merge`, and `#replace` accept objects which respond to `#to_hash`, even if those objects are not hashes directly. *Peter Jaros* * Deprecate `Class#superclass_delegating_accessor`, use `Class#class_attribute` instead. *Akshay Vishnoi* * Ensure classes which `include Enumerable` get `#to_json` in addition to `#as_json`. *Sammy Larbi* * Change the signature of `fetch_multi` to return a hash rather than an array. This makes it consistent with the output of `read_multi`. *Parker Selbert* * Introduce `Concern#class_methods` as a sleek alternative to clunky `module ClassMethods`. Add `Kernel#concern` to define at the toplevel without chunky `module Foo; extend ActiveSupport::Concern` boilerplate. # app/models/concerns/authentication.rb concern :Authentication do included do after_create :generate_private_key end class_methods do def authenticate(credentials) # ... end end def generate_private_key # ... end end # app/models/user.rb class User < ActiveRecord::Base include Authentication end *Jeremy Kemper* Please check [4-1-stable](https://github.com/rails/rails/blob/4-1-stable/activesupport/CHANGELOG.md) for previous changes.
