* `Rails.application.executor` hooks are now called around every tests.
|
||
|
||
This helps to better simulate request or job local state being reset around tests and prevent state
|
||
to leak from one test to another.
|
||
|
||
However it requires the executor hooks executed in the test environment to be re-entrant.
|

|
||
|
||
* `ActiveSupport::DescendantsTracker` now mostly delegate to `Class#descendants` on Ruby 3.1
|
||
|
||
Ruby now provides a fast `Class#descendants` making `ActiveSupport::DescendantsTracker` mostly useless.
|
||
|
||
As a result the following methods are deprecated:
|
||
|
||
- `ActiveSupport::DescendantsTracker.direct_descendants`
|
||
- `ActiveSupport::DescendantsTracker#direct_descendants`
|
||
|
||
*Jean Boussier*
|
||
|
||
* Fix the `Digest::UUID.uuid_from_hash` behavior for namespace IDs that are different from the ones defined on `Digest::UUID`.
|
||
|
||
The new behavior will be enabled by setting the
|
||
`config.active_support.use_rfc4122_namespaced_uuids` option to `true`
|
||
and is the default for new apps.
|
||
|
||
The old behavior is the default for upgraded apps and will output a
|
||
deprecation warning every time a value that is different than one of
|
||
the constants defined on the `Digest::UUID` extension is used as the
|
||
namespace ID.
|
||
|
||
*Alex Robbin*, *Erich Soares Machado*, *Eugene Kenny*
|
||
|
||
* `ActiveSupport::Inflector::Inflections#clear(:acronyms)` is now supported,
|
||
and `inflector.clear` / `inflector.clear(:all)` also clears acronyms.

## Rails 7.0.0.alpha2 (September 15, 2021) ##
|
||
|
||
* No changes.

## Rails 7.0.0.alpha1 (September 15, 2021) ##
|
||
|
||
* `ActiveSupport::Dependencies` no longer installs a `const_missing` hook. Before this, you could push to the autoload paths and have constants autoloaded. This feature, known as the `classic` autoloader, has been removed.
|
||
|
||
*Xavier Noria*
|
||
|
||
* Private internal classes of `ActiveSupport::Dependencies` have been deleted, like `ActiveSupport::Dependencies::Reference`, `ActiveSupport::Dependencies::Blamable`, and others.
|
||
|
||
*Xavier Noria*
|
||
|
||
* The private API of `ActiveSupport::Dependencies` has been deleted. That includes methods like `hook!`, `unhook!`, `depend_on`, `require_or_load`, `mechanism`, and many others.
|
||
|
||
*Xavier Noria*
|
||
|
||
* Improves the performance of `ActiveSupport::NumberHelper` formatters by avoiding the use of exceptions as flow control.
|
||
|
||
*Mike Dalessio*
|
||
|
||
* Removed rescue block from `ActiveSupport::Cache::RedisCacheStore#handle_exception`
|
||
|
||
Previously, if you provided a `error_handler` to `redis_cache_store`, any errors thrown by
|
||
the error handler would be rescued and logged only. Removed the `rescue` clause from `handle_exception`
|
||
to allow these to be thrown.
|
||
|
||
*Nicholas A. Stuart*
|
||
|
||
* Allow entirely opting out of deprecation warnings.
|
||
|
||
Previously if you did `app.config.active_support.deprecation = :silence`, some work would
|
||
still be done on each call to `ActiveSupport::Deprecation.warn`. In very hot paths, this could
|
||
cause performance issues.
|
||
|
||
Now, you can make `ActiveSupport::Deprecation.warn` a no-op:
|
||
|
||
```ruby
|
||
config.active_support.report_deprecations = false
|
||
```
|
||
|
||
This is the default in production for new apps. It is the equivalent to:
|
||
|
||
```ruby
|
||
config.active_support.deprecation = :silence
|
||
config.active_support.disallowed_deprecation = :silence
|
||
```
|
||
|
||
but will take a more optimised code path.
|
||
|
||
*Alex Ghiculescu*
|
||
|
||
* Faster tests by parallelizing only when overhead is justified by the number
|
||
of them.
|
||
|
||
Running tests in parallel adds overhead in terms of database
|
||
setup and fixture loading. Now, Rails will only parallelize test executions when
|
||
there are enough tests to make it worth it.
|
||
|
||
This threshold is 50 by default, and is configurable via config setting in
|
||
your test.rb:
|
||
|
||
```ruby
|
||
config.active_support.test_parallelization_threshold = 100
|
||
```
|
||
|
||
It's also configurable at the test case level:
|
||
|
||
```ruby
|
||
class ActiveSupport::TestCase
|
||
parallelize threshold: 100
|
||
end
|
||
```
|
||
|
||
*Jorge Manrubia*
|
||
|
||
* OpenSSL constants are now used for Digest computations.
|
||
|
||
*Dirkjan Bussink*
|
||
|
||
* `TimeZone.iso8601` now accepts valid ordinal values similar to Ruby's `Date._iso8601` method.
|
||
A valid ordinal value will be converted to an instance of `TimeWithZone` using the `:year`
|
||
and `:yday` fragments returned from `Date._iso8601`.
|
||
|
||
```ruby
|
||
twz = ActiveSupport::TimeZone["Eastern Time (US & Canada)"].iso8601("21087")
|
||
twz.to_a[0, 6] == [0, 0, 0, 28, 03, 2021]
|
||
```
|
||
|
||
*Steve Laing*
|
||
|
||
* `Time#change` and methods that call it (e.g. `Time#advance`) will now
|
||
return a `Time` with the timezone argument provided, if the caller was
|
||
initialized with a timezone argument.
|
||
|
||
Fixes [#42467](https://github.com/rails/rails/issues/42467).
|
||
|
||
*Alex Ghiculescu*
|
||
|
||
* Allow serializing any module or class to JSON by name.
|
||
|
||
*Tyler Rick*, *Zachary Scott*
|
||
|
||
* Raise `ActiveSupport::EncryptedFile::MissingKeyError` when the
|
||
`RAILS_MASTER_KEY` environment variable is blank (e.g. `""`).
|
||
|
||
*Sunny Ripert*
|
||
|
||
* The `from:` option is added to `ActiveSupport::TestCase#assert_no_changes`.
|
||
|
||
It permits asserting on the initial value that is expected not to change.
|
||
|
||
```ruby
|
||
assert_no_changes -> { Status.all_good? }, from: true do
|
||
post :create, params: { status: { ok: true } }
|
||
end
|
||
```
|
||
|
||
*George Claghorn*
|
||
|
||
* Deprecate `ActiveSupport::SafeBuffer`'s incorrect implicit conversion of objects into string.
|
||
|
||
Except for a few methods like `String#%`, objects must implement `#to_str`
|
||
to be implicitly converted to a String in string operations. In some
|
||
circumstances `ActiveSupport::SafeBuffer` was incorrectly calling the
|
||
explicit conversion method (`#to_s`) on them. This behavior is now
|
||
deprecated.
|
||
|
||
*Jean Boussier*
|
||
|
||
* Allow nested access to keys on `Rails.application.credentials`.
|
||
|
||
Previously only top level keys in `credentials.yml.enc` could be accessed with method calls. Now any key can.
|
||
|
||
For example, given these secrets:
|
||
|
||
```yml
|
||
aws:
|
||
access_key_id: 123
|
||
secret_access_key: 345
|
||
```
|
||
|
||
`Rails.application.credentials.aws.access_key_id` will now return the same thing as
|
||
`Rails.application.credentials.aws[:access_key_id]`.
|
||
|
||
*Alex Ghiculescu*
|
||
|
||
* Added a faster and more compact `ActiveSupport::Cache` serialization format.
|
||
|
||
It can be enabled with `config.active_support.cache_format_version = 7.0` or
|
||
`config.load_defaults 7.0`. Regardless of the configuration Active Support
|
||
7.0 can read cache entries serialized by Active Support 6.1 which allows to
|
||
upgrade without invalidating the cache. However Rails 6.1 can't read the
|
||
new format, so all readers must be upgraded before the new format is enabled.
|
||
|
||
*Jean Boussier*
|
||
|
||
* Add `Enumerable#sole`, per `ActiveRecord::FinderMethods#sole`. Returns the
|
||
sole item of the enumerable, raising if no items are found, or if more than
|
||
one is.
|
||
|
||
*Asherah Connor*
|
||
|
||
* Freeze `ActiveSupport::Duration#parts` and remove writer methods.
|
||
|
||
Durations are meant to be value objects and should not be mutated.
|
||
|
||
*Andrew White*
|
||
|
||
* Fix `ActiveSupport::TimeZone#utc_to_local` with fractional seconds.
|
||
|
||
When `utc_to_local_returns_utc_offset_times` is false and the time
|
||
instance had fractional seconds the new UTC time instance was out by
|
||
a factor of 1,000,000 as the `Time.utc` constructor takes a usec
|
||
value and not a fractional second value.
|
||
|
||
*Andrew White*
|
||
|
||
* Add `expires_at` argument to `ActiveSupport::Cache` `write` and `fetch` to set a cache entry TTL as an absolute time.
|
||
|
||
```ruby
|
||
Rails.cache.write(key, value, expires_at: Time.now.at_end_of_hour)
|
||
```
|
||
|
||
*Jean Boussier*
|
||
|
||
* Deprecate `ActiveSupport::TimeWithZone.name` so that from Rails 7.1 it will use the default implementation.
|
||
|
||
*Andrew White*
|
||
|
||
* Deprecates Rails custom `Enumerable#sum` and `Array#sum` in favor of Ruby's native implementation which
|
||
is considerably faster.
|
||
|
||
Ruby requires an initializer for non-numeric type as per examples below:
|
||
|
||
```ruby
|
||
%w[foo bar].sum('')
|
||
# instead of %w[foo bar].sum
|
||
|
||
[[1, 2], [3, 4, 5]].sum([])
|
||
# instead of [[1, 2], [3, 4, 5]].sum
|
||
```
|
||
|
||
*Alberto Mota*
|
||
|
||
* Tests parallelization is now disabled when running individual files to prevent the setup overhead.
|
||
|
||
It can still be enforced if the environment variable `PARALLEL_WORKERS` is present and set to a value greater than 1.
|
||
|
||
*Ricardo Díaz*
|
||
|
||
* Fix proxying keyword arguments in `ActiveSupport::CurrentAttributes`.
|
||
|
||
*Marcin Kołodziej*
|
||
|
||
* Add `Enumerable#maximum` and `Enumerable#minimum` to easily calculate the maximum or minimum from extracted
|
||
elements of an enumerable.
|
||
|
||
```ruby
|
||
payments = [Payment.new(5), Payment.new(15), Payment.new(10)]
|
||
|
||
payments.minimum(:price) # => 5
|
||
payments.maximum(:price) # => 15
|
||
```
|
||
|
||
This also allows passing enumerables to `fresh_when` and `stale?` in Action Controller.
|
||
See PR [#41404](https://github.com/rails/rails/pull/41404) for an example.
|
||
|
||
*Ayrton De Craene*
|
||
|
||
* `ActiveSupport::Cache::MemCacheStore` now accepts an explicit `nil` for its `addresses` argument.
|
||
|
||
```ruby
|
||
config.cache_store = :mem_cache_store, nil
|
||
|
||
# is now equivalent to
|
||
|
||
config.cache_store = :mem_cache_store
|
||
|
||
# and is also equivalent to
|
||
|
||
config.cache_store = :mem_cache_store, ENV["MEMCACHE_SERVERS"] || "localhost:11211"
|
||
|
||
# which is the fallback behavior of Dalli
|
||
```
|
||
|
||
This helps those migrating from `:dalli_store`, where an explicit `nil` was permitted.
|
||
|
||
*Michael Overmeyer*
|
||
|
||
* Add `Enumerable#in_order_of` to put an Enumerable in a certain order by a key.
|
||
|
||
*DHH*
|
||
|
||
* `ActiveSupport::Inflector.camelize` behaves expected when provided a symbol `:upper` or `:lower` argument. Matches
|
||
`String#camelize` behavior.
|
||
|
||
*Alex Ghiculescu*
|
||
|
||
* Raises an `ArgumentError` when the first argument of `ActiveSupport::Notification.subscribe` is
|
||
invalid.
|
||
|
||
*Vipul A M*
|
||
|
||
* `HashWithIndifferentAccess#deep_transform_keys` now returns a `HashWithIndifferentAccess` instead of a `Hash`.
|
||
|
||
*Nathaniel Woodthorpe*
|
||
|
||
* Consume dalli’s `cache_nils` configuration as `ActiveSupport::Cache`'s `skip_nil` when using `MemCacheStore`.
|
||
|
||
*Ritikesh G*
|
||
|
||
* Add `RedisCacheStore#stats` method similar to `MemCacheStore#stats`. Calls `redis#info` internally.
|
||
|
||
