Coalesce related bits and give them definition. - These are a stepping stone toward future growth & refactoring. - - When to move on from an inline concern: - * Encapsulating state? Extract collaborator object. - * Encompassing more public behavior or implementation? Move to separate file. - * Sharing behavior among classes? Move to separate file. - - *Jeremy Kemper* - -* Fix file descriptor being leaked on each call to `Kernel.silence_stream`. - - *Mario Visic* - -* Added `Date#all_week/month/quarter/year` for generating date ranges. - - *Dmitriy Meremyanin* + Time.zone.now.end_of_day - Time.zone.now.beginning_of_day + #=> 86399.999999999 -* Add `Time.zone.yesterday` and `Time.zone.tomorrow`.

The new encoder will always - encode BigDecimals as `String`s and ignore any custom `encode_json` methods. + Replacements: - The old encoder has been extracted into the `activesupport-json_encoder` gem. Installing that - gem will bring back the ability to encode `BigDecimal`s as numbers as well as `encode_json` - support. + 5.ago => 5.seconds.ago + 5.until => 5.seconds.until + 5.since => 5.seconds.since + 5.from_now => 5.seconds.from_now - Setting the related configuration `ActiveSupport.encode_big_decimal_as_string` without the - `activesupport-json_encoder` gem installed will raise an error. + See #12389 for the history and rationale behind this. *Godfrey Chan* -* Add `ActiveSupport::Testing::TimeHelpers#travel` and `#travel_to`. These methods change current - time to the given time or time difference by stubbing `Time.now` and `Date.today` to return the - time or date after the difference calculation, or the time or date that got passed into the - method respectively. - - Example for `#travel`: - - Time.now # => 2013-11-09 15:34:49 -05:00 - travel 1.day - Time.now # => 2013-11-10 15:34:49 -05:00 - Date.today # => Sun, 10 Nov 2013 - - Example for `#travel_to`: - - Time.now # => 2013-11-09 15:34:49 -05:00 - travel_to Time.new(2004, 11, 24, 01, 04, 44) - Time.now # => 2004-11-24 01:04:44 -05:00 - Date.today # => Wed, 24 Nov 2004 +* DateTime `advance` now supports partial days. - Both of these methods also accept a block, which will return the current time back to its - original state at the end of the block: - - Time.now # => 2013-11-09 15:34:49 -05:00 - - travel 1.day do - User.create.created_at # => Sun, 10 Nov 2013 15:34:49 EST -05:00 - end - - travel_to Time.new(2004, 11, 24, 01, 04, 44) do - User.create.created_at # => Wed, 24 Nov 2004 01:04:44 EST -05:00 - end - - Time.now # => 2013-11-09 15:34:49 -05:00 - - This module is included in `ActiveSupport::TestCase` automatically. - - *Prem Sichanugrist*, *DHH* + Before: -* Unify `cattr_*` interface: allow to pass a block to `cattr_reader`. + DateTime.now.advance(days: 1, hours: 12) - Example: + After: - class A - cattr_reader(:defr) { 'default_reader_value' } - end - A.defr # => 'default_reader_value' + DateTime.now.advance(days: 1.5) - *Alexey Chernenkov* + Fixes #12005. -* Improved compatibility with the stdlib JSON gem. + *Shay Davidson* - Previously, calling `::JSON.{generate,dump}` sometimes causes unexpected - failures such as intridea/multi_json#86. +* `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!`. - `::JSON.{generate,dump}` now bypasses the ActiveSupport JSON encoder - completely and yields the same result with or without ActiveSupport. This - means that it will **not** call `as_json` and will ignore any options that - the JSON gem does not natively understand. To invoke ActiveSupport's JSON - encoder instead, use `obj.to_json(options)` or - `ActiveSupport::JSON.encode(obj, options)`. + *OZAWA Sakuro* - *Godfrey Chan* +* Fixed confusing `DelegationError` in `Module#delegate`. -* Fix Active Support `Time#to_json` and `DateTime#to_json` to return 3 decimal - places worth of fractional seconds, similar to `TimeWithZone`. + See #15186. - *Ryan Glover* + *Vladimir Yarotsky* -* Removed circular reference protection in JSON encoder, deprecated - `ActiveSupport::JSON::Encoding::CircularReferenceError`. +* Fixed `ActiveSupport::Subscriber` so that no duplicate subscriber is created + when a subscriber method is redefined. - *Godfrey Chan*, *Sergio Campamá* + *Dennis Schön* -* Add `capitalize` option to `Inflector.humanize`, so strings can be humanized without being capitalized: +* Remove deprecated string based terminators for `ActiveSupport::Callbacks`. - 'employee_salary'.humanize # => "Employee salary" - 'employee_salary'.humanize(capitalize: false) # => "employee salary" + *Eileen M. Uchitelle* - *claudiob* +* Fixed an issue when using + `ActiveSupport::NumberHelper::NumberToDelimitedConverter` to + convert a value that is an `ActiveSupport::SafeBuffer` introduced + in 2da9d67. -* Fixed `Object#as_json` and `Struct#as_json` not working properly with options. They now take - the same options as `Hash#as_json`: + See #15064. - struct = Struct.new(:foo, :bar).new - struct.foo = "hello" - struct.bar = "world" - json = struct.as_json(only: [:foo]) # => {foo: "hello"} + *Mark J. Titorenko* - *Sergio Campamá*, *Godfrey Chan* +* `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`. -* Added `Numeric#in_milliseconds`, like `1.hour.in_milliseconds`, so we can feed them to JavaScript functions like `getTime()`. + *Ulysse Carion* - *DHH* +* `humanize` strips leading underscores, if any. -* Calling `ActiveSupport::JSON.decode` with unsupported options now raises an error. + Before: - *Godfrey Chan* + '_id'.humanize # => "" -* Support `:unless_exist` in `FileStore`. + After: - *Michael Grosser* + '_id'.humanize # => "Id" -* Fix `slice!` deleting the default value of the hash. + *Xavier Noria* - *Antonio Santos* +* Fixed backward compatibility isues introduced in 326e652. -* `require_dependency` accepts objects that respond to `to_path`, in - particular `Pathname` instances. + Empty Hash or Array should not present in serialization result. - *Benjamin Fleischer* + {a: []}.to_query # => "" + {a: {}}.to_query # => "" -* Disable the ability to iterate over Range of AS::TimeWithZone - due to significant performance issues. + For more info see #14948. *Bogdan Gusiev* -* Allow attaching event subscribers to ActiveSupport::Notifications namespaces - before they're defined. Essentially, this means instead of this: +* Add `Digest::UUID::uuid_v3` and `Digest::UUID::uuid_v5` to support stable + UUID fixtures on PostgreSQL. - class JokeSubscriber < ActiveSupport::Subscriber - def sql(event) - puts "A rabbi and a priest walk into a bar..." - end + *Roderick van Domburg* - # This call needs to happen *after* defining the methods. - attach_to "active_record" - end +* Fixed `ActiveSupport::Duration#eql?` so that `1.second.eql?(1.second)` is + true. - You can do this: + This fixes the current situation of: - class JokeSubscriber < ActiveSupport::Subscriber - # This is much easier to read! - attach_to "active_record" + 1.second.eql?(1.second) #=> false - def sql(event) - puts "A rabbi and a priest walk into a bar..." - end - end - - This should make it easier to read and understand these subscribers. + `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: - *Daniel Schierbeck* + 1.eql?(1.0) #=> false + 1.0.eql?(1) #=> false -* Add `Date#middle_of_day`, `DateTime#middle_of_day` and `Time#middle_of_day` methods. + 1.second.eql?(1) #=> false (was true) + 1.eql?(1.second) #=> false - Also added `midday`, `noon`, `at_midday`, `at_noon` and `at_middle_of_day` as aliases. + { 1 => "foo", 1.0 => "bar" } + #=> { 1 => "foo", 1.0 => "bar" } - *Anatoli Makarevich* + { 1 => "foo", 1.second => "bar" } + # now => { 1 => "foo", 1.second => "bar" } + # was => { 1 => "bar" } -* Fix ActiveSupport::Cache::FileStore#cleanup to no longer rely on missing each_key method. + And though the behavior of these hasn't changed, for reference: - *Murray Steele* + 1 == 1.0 #=> true + 1.0 == 1 #=> true -* Ensure that autoloaded constants in all-caps nestings are marked as - autoloaded. + 1 == 1.second #=> true + 1.second == 1 #=> true - *Simon Coffey* + *Emily Dobervich* -* Add `String#remove(pattern)` as a short-hand for the common pattern of - `String#gsub(pattern, '')`. +* `ActiveSupport::SafeBuffer#prepend` acts like `String#prepend` and modifies + instance in-place, returning self. `ActiveSupport::SafeBuffer#prepend!` is + deprecated. - *DHH* + *Pavel Pravosud* -* Adds a new deprecation behaviour that raises an exception. Throwing this - line into +config/environments/development.rb+ +* `HashWithIndifferentAccess` better respects `#to_hash` on objects it's + given. In particular, `.new`, `#update`, `#merge`, `#replace` all accept + objects which respond to `#to_hash`, even if those objects are not Hashes + directly. - ActiveSupport::Deprecation.behavior = :raise + *Peter Jaros* - will cause the application to raise an +ActiveSupport::DeprecationException+ - on deprecations. +* Deprecate `Class#superclass_delegating_accessor`, use `Class#class_attribute` instead. - Use this for aggressive deprecation cleanups. - - *Xavier Noria* + *Akshay Vishnoi* -* Remove 'cow' => 'kine' irregular inflection from default inflections. +* Ensure classes which `include Enumerable` get `#to_json` in addition to + `#as_json`. - *Andrew White* + *Sammy Larbi* -* Add `DateTime#to_s(:iso8601)` and `Date#to_s(:iso8601)` for consistency. +* Change the signature of `fetch_multi` to return a hash rather than an + array. This makes it consistent with the output of `read_multi`. - *Andrew White* + *Parker Selbert* -* Add `Time#to_s(:iso8601)` for easy conversion of times to the iso8601 format for easy Javascript date parsing. +* Introduce `Concern#class_methods` as a sleek alternative to clunky + `module ClassMethods`.
