* 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, so you can do this:
person.try { name.first }
instead of:
person.try { |person| person.name.first }
*DHH*
* 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.
