Raw Blame History

* 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.
