* `ActiveSupport::TimeZone.country_zones(country_code)` looks up the
country's time zones by its two-letter ISO3166 country code, e.g.
>> ActiveSupport::TimeZone.country_zones(:jp).map(&:to_s)
=> ["(GMT+09:00) Osaka"]
>> ActiveSupport::TimeZone.country_zones(:uy).map(&:to_s)
=> ["(GMT-03:00) Montevideo"]
*Andrey Novikov*
* `Array#sum` compat with Ruby 2.4's native method.
Ruby 2.4 introduces `Array#sum`, but it only supports numeric elements,
breaking our `Enumerable#sum` which supports arbitrary `Object#+`.
To fix, override `Array#sum` with our compatible implementation.
Native Ruby 2.4:
%w[ a b ].sum
# => TypeError: String can't be coerced into Fixnum
With `Enumerable#sum` shim:
%w[ a b ].sum
# => 'ab'
We tried shimming the fast path and falling back to the compatible path
if it fails, but that ends up slower even in simple cases due to the cost
of exception handling. Our only choice is to override the native `Array#sum`
with our `Enumerable#sum`.
*Jeremy Daer*
* `ActiveSupport::Duration` supports ISO8601 formatting and parsing.
ActiveSupport::Duration.parse('P3Y6M4DT12H30M5S')
# => 3 years, 6 months, 4 days, 12 hours, 30 minutes, and 5 seconds
(3.years + 3.days).iso8601
# => "P3Y3D"
Inspired by Arnau Siches' [ISO8601 gem](https://github.com/arnau/ISO8601/)
and rewritten by Andrey Novikov with suggestions from Andrew White. Test
data from the ISO8601 gem redistributed under MIT license.
(Will be used to support the PostgreSQL interval data type.)
*Andrey Novikov*, *Arnau Siches*, *Andrew White*
* `Cache#fetch(key, force: true)` forces a cache miss, so it must be called
with a block to provide a new value to cache. Fetching with `force: true`
but without a block now raises ArgumentError.
cache.fetch('key', force: true) # => ArgumentError
*Santosh Wadghule*
* `ActiveSupport::Duration` supports weeks and hours.
[1.hour.inspect, 1.hour.value, 1.hour.parts]
# => ["3600 seconds", 3600, [[:seconds, 3600]]] # Before
# => ["1 hour", 3600, [[:hours, 1]]] # After
[1.week.inspect, 1.week.value, 1.week.parts]
# => ["7 days", 604800, [[:days, 7]]] # Before
# => ["1 week", 604800, [[:weeks, 1]]] # After
This brings us into closer conformance with ISO8601 and relieves some
astonishment about getting `1.hour.inspect # => 3600 seconds`.
Compatibility: The duration's `value` remains the same, so apps using
durations are oblivious to the new time periods. Apps, libraries, and
plugins that work with the internal `parts` hash will need to broaden
their time period handling to cover hours & weeks.
*Andrey Novikov*
* Fix behavior of JSON encoding for `Exception`.
*namusyaka*
* Make `number_to_phone` format number with regexp pattern.
number_to_phone(18812345678, pattern: /(\d{3})(\d{4})(\d{4})/)
# => 188-1234-5678
*Pan Gaoyong*
* Match `String#to_time`'s behaviour to that of ruby's implementation for edge cases.
`nil` is now returned instead of the current date if the string provided does
contain time information, but none that is used to build the `Time` object.
Fixes #22958.
*Siim Liiser*
* Rely on the native DateTime#<=> implementation to handle non-datetime like
objects instead of returning `nil` ourselves. This restores the ability
of `DateTime` instances to be compared with a `Numeric` that represents an
astronomical julian day number.
Fixes #24228.
*Andrew White*
* Add `String#upcase_first` method.
*Glauco Custódio*, *bogdanvlviv*
* Prevent `Marshal.load` from looping infinitely when trying to autoload a constant
which resolves to a different name.
*Olek Janiszewski*
* Deprecate `Module.local_constants`. Please use `Module.constants(false)` instead.
*Yuichiro Kaneko*
* Publish `ActiveSupport::Executor` and `ActiveSupport::Reloader` APIs to allow
components and libraries to manage, and participate in, the execution of
application code, and the application reloading process.
*Matthew Draper*
## Rails 5.0.0.beta3 (February 24, 2016) ##
* Deprecate arguments on `assert_nothing_raised`.
`assert_nothing_raised` does not assert the arguments that have been passed
in (usually a specific exception class) since the method only yields the
block. So as not to confuse the users that the arguments have meaning, they
are being deprecated.
*Tara Scherner de la Fuente*
* Make `benchmark('something', silence: true)` actually work.
*DHH*
* Add `#on_weekday?` method to `Date`, `Time`, and `DateTime`.
`#on_weekday?` returns `true` if the receiving date/time does not fall on a Saturday
or Sunday.
*Vipul A M*
* Add `Array#second_to_last` and `Array#third_to_last` methods.
*Brian Christian*
* Fix regression in `Hash#dig` for HashWithIndifferentAccess.
*Jon Moss*
## Rails 5.0.0.beta2 (February 01, 2016) ##
* Change `number_to_currency` behavior for checking negativity.
Used `to_f.negative` instead of using `to_f.phase` for checking negativity
of a number in number_to_currency helper.
This change works same for all cases except when number is "-0.0".
-0.0.to_f.negative? => false
-0.0.to_f.phase? => 3.14
This change reverts changes from https://github.com/rails/rails/pull/6512.
But it should be acceptable as we could not find any currency which
supports negative zeros.
*Prathamesh Sonpatki*, *Rafael Mendonça França*
* Match `HashWithIndifferentAccess#default`'s behaviour with `Hash#default`.
*David Cornu*
* Adds `:exception_object` key to `ActiveSupport::Notifications::Instrumenter`
payload when an exception is raised.
Adds new key/value pair to payload when an exception is raised:
e.g. `:exception_object => #<RuntimeError: FAIL>`.
*Ryan T. Hosford*
* Support extended grapheme clusters and UAX 29.
*Adam Roben*
* Add petabyte and exabyte numeric conversion.
*Akshay Vishnoi*
## Rails 5.0.0.beta1 (December 18, 2015) ##
* Add thread_m/cattr_accessor/reader/writer suite of methods for declaring class and module variables that live per-thread.
This makes it easy to declare per-thread globals that are encapsulated. Note: This is a sharp edge. A wild proliferation
of globals is A Bad Thing. But like other sharp tools, when it's right, it's right.
Here's an example of a simple event tracking system where the object being tracked needs not pass a creator that it
doesn't need itself along:
module Current
thread_mattr_accessor :account
thread_mattr_accessor :user
def self.reset() self.account = self.user = nil end
end
class ApplicationController < ActionController::Base
before_action :set_current
after_action { Current.reset }
private
def set_current
Current.account = Account.find(params[:account_id])
Current.user = Current.account.users.find(params[:user_id])
end
end
class MessagesController < ApplicationController
def create
@message = Message.create!(message_params)
end
end
class Message < ApplicationRecord
has_many :events
after_create :track_created
private
def track_created
events.create! origin: self, action: :create
end
end
class Event < ApplicationRecord
belongs_to :creator, class_name: 'User'
before_validation { self.creator ||= Current.user }
end
*DHH*
* Deprecated `Module#qualified_const_` in favour of the builtin Module#const_
methods.
*Genadi Samokovarov*
* Deprecate passing string to define callback.
*Yuichiro Kaneko*
* `ActiveSupport::Cache::Store#namespaced_key`,
`ActiveSupport::Cache::MemCachedStore#escape_key`, and
`ActiveSupport::Cache::FileStore#key_file_path`
are deprecated and replaced with `normalize_key` that now calls `super`.
`ActiveSupport::Cache::LocaleCache#set_cache_value` is deprecated and replaced with `write_cache_value`.
*Michael Grosser*
* Implements an evented file watcher to asynchronously detect changes in the
application source code, routes, locales, etc.
This watcher is disabled by default, applications my enable it in the configuration:
# config/environments/development.rb
config.file_watcher = ActiveSupport::EventedFileUpdateChecker
This feature depends on the [listen](https://github.com/guard/listen) gem:
group :development do
gem 'listen', '~> 3.0.5'
end
*Puneet Agarwal* and *Xavier Noria*
* Added `Time.days_in_year` to return the number of days in the given year, or the
current year if no argument is provided.
*Jon Pascoe*
* Updated `parameterize` to preserve the case of a string, optionally.
Example:
parameterize("Donald E. Knuth", separator: '_') # => "donald_e_knuth"
parameterize("Donald E. Knuth", preserve_case: true) # => "Donald-E-Knuth"
*Swaathi Kakarla*
* `HashWithIndifferentAccess.new` respects the default value or proc on objects
that respond to `#to_hash`. `.new_from_hash_copying_default` simply invokes `.new`.
All calls to `.new_from_hash_copying_default` are replaced with `.new`.
*Gordon Chan*
* Change Integer#year to return a Fixnum instead of a Float to improve
consistency.
Integer#years returned a Float while the rest of the accompanying methods
(days, weeks, months, etc.) return a Fixnum.
Before:
1.year # => 31557600.0
After:
1.year # => 31557600
*Konstantinos Rousis*
* Handle invalid UTF-8 strings when HTML escaping.
Use `ActiveSupport::Multibyte::Unicode.tidy_bytes` to handle invalid UTF-8
strings in `ERB::Util.unwrapped_html_escape` and `ERB::Util.html_escape_once`.
Prevents user-entered input passed from a querystring into a form field from
causing invalid byte sequence errors.
*Grey Baker*
* Update `ActiveSupport::Multibyte::Chars#slice!` to return `nil` if the
arguments are out of bounds, to mirror the behavior of `String#slice!`
*Gourav Tiwari*
* Fix `number_to_human` so that 999999999 rounds to "1 Billion" instead of
"1000 Million".
*Max Jacobson*
* Fix `ActiveSupport::Deprecation#deprecate_methods` to report using the
current deprecator instance, where applicable.
*Brandon Dunne*
* `Cache#fetch` instrumentation marks whether it was a `:hit`.
*Robin Clowers*
* `assert_difference` and `assert_no_difference` now returns the result of the
yielded block.
Example:
post = assert_difference -> { Post.count }, 1 do
Post.create
end
*Lucas Mazza*
* Short-circuit `blank?` on date and time values since they are never blank.
Fixes #21657.
*Andrew White*
* Replaced deprecated `ThreadSafe::Cache` with its successor `Concurrent::Map` now that
the thread_safe gem has been merged into concurrent-ruby.
*Jerry D'Antonio*
* Updated Unicode version to 8.0.0
*Anshul Sharma*
* `number_to_currency` and `number_with_delimiter` now accept custom `delimiter_pattern` option
to handle placement of delimiter, to support currency formats like INR
Example:
number_to_currency(1230000, delimiter_pattern: /(\d+?)(?=(\d\d)+(\d)(?!\d))/, unit: '₹', format: "%u %n")
# => '₹ 12,30,000.00'
*Vipul A M*
* Deprecate `:prefix` option of `number_to_human_size` with no replacement.
*Jean Boussier*
* Fix `TimeWithZone#eql?` to properly handle `TimeWithZone` created from `DateTime`:
twz = DateTime.now.in_time_zone
twz.eql?(twz.dup) => true
Fixes #14178.
*Roque Pinel*
* ActiveSupport::HashWithIndifferentAccess `select` and `reject` will now return
enumerator if called without block.
Fixes #20095.
*Bernard Potocki*
* Removed `ActiveSupport::Concurrency::Latch`, superseded by `Concurrent::CountDownLatch`
from the concurrent-ruby gem.
*Jerry D'Antonio*
* Fix not calling `#default` on `HashWithIndifferentAccess#to_hash` when only
`default_proc` is set, which could raise.
*Simon Eskildsen*
* Fix setting `default_proc` on `HashWithIndifferentAccess#dup`.
*Simon Eskildsen*
* Fix a range of values for parameters of the Time#change.
*Nikolay Kondratyev*
* Add `Enumerable#pluck` to get the same values from arrays as from ActiveRecord
associations.
Fixes #20339.
*Kevin Deisz*
* Add a bang version to `ActiveSupport::OrderedOptions` get methods which will raise
an `KeyError` if the value is `.blank?`.
Before:
if (slack_url = Rails.application.secrets.slack_url).present?
# Do something worthwhile
else
# Raise as important secret password is not specified
end
After:
slack_url = Rails.application.secrets.slack_url!
*Aditya Sanghi*, *Gaurish Sharma*
* Remove deprecated `Class#superclass_delegating_accessor`.
Use `Class#class_attribute` instead.
*Akshay Vishnoi*
* Patch `Delegator` to work with `#try`.
Fixes #5790.
*Nate Smith*
* Add `Integer#positive?` and `Integer#negative?` query methods
in the vein of `Fixnum#zero?`.
This makes it nicer to do things like `bunch_of_numbers.select(&:positive?)`.
*DHH*
* Encoding `ActiveSupport::TimeWithZone` to YAML now preserves the timezone information.
Fixes #9183.
*Andrew White*
* Added `ActiveSupport::TimeZone#strptime` to allow parsing times as if
from a given timezone.
*Paul A Jungwirth*
* `ActiveSupport::Callbacks#skip_callback` now raises an `ArgumentError` if
an unrecognized callback is removed.
*Iain Beeston*
* Added `ActiveSupport::ArrayInquirer` and `Array#inquiry`.
Wrapping an array in an `ArrayInquirer` gives a friendlier way to check its
contents:
variants = ActiveSupport::ArrayInquirer.new([:phone, :tablet])
variants.phone? # => true
variants.tablet? # => true
variants.desktop? # => false
variants.any?(:phone, :tablet) # => true
variants.any?(:phone, :desktop) # => true
variants.any?(:desktop, :watch) # => false
`Array#inquiry` is a shortcut for wrapping the receiving array in an
`ArrayInquirer`.
*George Claghorn*
* Deprecate `alias_method_chain` in favour of `Module#prepend` introduced in
Ruby 2.0.
*Kir Shatrov*
* Added `#without` on `Enumerable` and `Array` to return a copy of an
enumerable without the specified elements.
*Todd Bealmear*
* 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*
* Enable `number_to_percentage` to keep the number's precision by allowing
`:precision` to be `nil`.
*Jack Xu*
* `config_accessor` became a private method, as with Ruby's `attr_accessor`.
*Akira Matsuda*
* `AS::Testing::TimeHelpers#travel_to` now changes `DateTime.now` as well as
`Time.now` and `Date.today`.
*Yuki Nishijima*
* Add `file_fixture` to `ActiveSupport::TestCase`.
It provides a simple mechanism to access sample files in your test cases.
By default file fixtures are stored in `test/fixtures/files`. This can be
configured per test-case using the `file_fixture_path` class attribute.
*Yves Senn*
* Return value of yielded block in `File.atomic_write`.
*Ian Ker-Seymer*
* Duplicate frozen array when assigning it to a `HashWithIndifferentAccess` so
that it doesn't raise a `RuntimeError` when calling `map!` on it in `convert_value`.
Fixes #18550.
*Aditya Kapoor*
* Add missing time zone definitions for Russian Federation and sync them
with `zone.tab` file from tzdata version 2014j (latest).
*Andrey Novikov*
* Add `SecureRandom.base58` for generation of random base58 strings.
*Matthew Draper*, *Guillermo Iguaran*
* Add `#prev_day` and `#next_day` counterparts to `#yesterday` and
`#tomorrow` for `Date`, `Time`, and `DateTime`.
*George Claghorn*
* Add `same_time` option to `#next_week` and `#prev_week` for `Date`, `Time`,
and `DateTime`.
*George Claghorn*
* Add `#on_weekend?`, `#next_weekday`, `#prev_weekday` methods to `Date`,
`Time`, and `DateTime`.
`#on_weekend?` returns `true` if the receiving date/time falls on a Saturday
or Sunday.
`#next_weekday` returns a new date/time representing the next day that does
not fall on a Saturday or Sunday.
`#prev_weekday` returns a new date/time representing the previous day that
does not fall on a Saturday or Sunday.
*George Claghorn*
* Change the default test order from `:sorted` to `:random`.
*Rafael Mendonça França*
* Remove deprecated `ActiveSupport::JSON::Encoding::CircularReferenceError`.
*Rafael Mendonça França*
* Remove deprecated methods `ActiveSupport::JSON::Encoding.encode_big_decimal_as_string=`
and `ActiveSupport::JSON::Encoding.encode_big_decimal_as_string`.
*Rafael Mendonça França*
* Remove deprecated `ActiveSupport::SafeBuffer#prepend`.
*Rafael Mendonça França*
* Remove deprecated methods at `Kernel`.
`silence_stderr`, `silence_stream`, `capture` and `quietly`.
*Rafael Mendonça França*
* Remove deprecated `active_support/core_ext/big_decimal/yaml_conversions`
file.
*Rafael Mendonça França*
* Remove deprecated methods `ActiveSupport::Cache::Store.instrument` and
`ActiveSupport::Cache::Store.instrument=`.
*Rafael Mendonça França*
* Change the way in which callback chains can be halted.
The preferred method to halt a callback chain from now on is to explicitly
`throw(:abort)`.
In the past, callbacks could only be halted by explicitly providing a
terminator and by having a callback match the conditions of the terminator.
* Add `ActiveSupport.halt_callback_chains_on_return_false`
Setting `ActiveSupport.halt_callback_chains_on_return_false`
to `true` will let an app support the deprecated way of halting Active Record,
and Active Model callback chains by returning `false`.
Setting the value to `false` will tell the app to ignore any `false` value
returned by those callbacks, and only halt the chain upon `throw(:abort)`.
When the configuration option is missing, its value is `true`, so older apps
ported to Rails 5.0 will not break (but display a deprecation warning).
For new Rails 5.0 apps, its value is set to `false` in an initializer, so
these apps will support the new behavior by default.
*claudiob*, *Roque Pinel*
* Changes arguments and default value of CallbackChain's `:terminator` option
Chains of callbacks defined without an explicit `:terminator` option will
now be halted as soon as a `before_` callback throws `:abort`.
Chains of callbacks defined with a `:terminator` option will maintain their
existing behavior of halting as soon as a `before_` callback matches the
terminator's expectation.
*claudiob*
* Deprecate `MissingSourceFile` in favor of `LoadError`.
`MissingSourceFile` was just an alias to `LoadError` and was not being
raised inside the framework.
*Rafael Mendonça França*
* Add support for error dispatcher classes in `ActiveSupport::Rescuable`.
Now it acts closer to Ruby's rescue.
Example:
class BaseController < ApplicationController
module ErrorDispatcher
def self.===(other)
Exception === other && other.respond_to?(:status)
end
end
rescue_from ErrorDispatcher do |error|
render status: error.status, json: { error: error.to_s }
end
end
*Genadi Samokovarov*
* Add `#verified` and `#valid_message?` methods to `ActiveSupport::MessageVerifier`
Previously, the only way to decode a message with `ActiveSupport::MessageVerifier`
was to use `#verify`, which would raise an exception on invalid messages. Now
`#verified` can also be used, which returns `nil` on messages that cannot be
decoded.
Previously, there was no way to check if a message's format was valid without
attempting to decode it. `#valid_message?` is a boolean convenience method that
checks whether the message is valid without actually decoding it.
*Logan Leger*
