#### Active Support
- Handle nil `backtrace_locations` in `ActiveSupport::SyntaxErrorProxy`.
*Eugene Kenny*
- Fix `ActiveSupport::JSON.encode` to prevent duplicate keys.
If the same key exist in both String and Symbol form it could
lead to the same key being emitted twice.
*Manish Sharma*
- Fix `ActiveSupport::Cache::Store#read_multi` when using a cache namespace
and local cache strategy.
*Mark Oleson*
- Fix `Time.now/DateTime.now/Date.today` to return results in a system timezone after `#travel_to`.
There is a bug in the current implementation of #travel_to:
it remembers a timezone of its argument, and all stubbed methods start
returning results in that remembered timezone. However, the expected
behaviour is to return results in a system timezone.
*Aleksei Chernenkov*
- Fix `:unless_exist` option for `MemoryStore#write` (et al) when using a
cache namespace.
*S. Brent Faulkner*
- Fix ActiveSupport::Deprecation to handle blaming generated code.
*Jean Boussier*, *fatkodima*
#### Active Model
- No changes.
#### Active Record
- Fix Migrations with versions older than 7.1 validating options given to
`add_reference`.
*Hartley McGuire*
- Ensure `reload` sets correct owner for each association.
*Dmytro Savochkin*
- Fix view runtime for controllers with async queries.
*fatkodima*
- Fix `load_async` to work with query cache.
*fatkodima*
- Fix polymorphic `belongs_to` to correctly use parent's `query_constraints`.
*fatkodima*
- Fix `Preloader` to not generate a query for already loaded association with `query_constraints`.
*fatkodima*
- Fix multi-database polymorphic preloading with equivalent table names.
When preloading polymorphic associations, if two models pointed to two
tables with the same name but located in different databases, the
preloader would only load one.
*Ari Summer*
- Fix `encrypted_attribute?` to take into account context properties passed to `encrypts`.
*Maxime Réty*
- Fix `find_by` to work correctly in presence of composite primary keys.
*fatkodima*
- Fix async queries sometimes returning a raw result if they hit the query cache.
`ShipPart.async_count` could return a raw integer rather than a Promise
if it found the result in the query cache.
*fatkodima*
- Fix `Relation#transaction` to not apply a default scope.
The method was incorrectly setting a default scope around its block:
```ruby
Post.where(published: true).transaction do
Post.count # SELECT COUNT(*) FROM posts WHERE published = FALSE;
end
```
*Jean Boussier*
- Fix calling `async_pluck` on a `none` relation.
`Model.none.async_pluck(:id)` was returning a naked value
instead of a promise.
*Jean Boussier*
- Fix calling `load_async` on a `none` relation.
`Model.none.load_async` was returning a broken result.
*Lucas Mazza*
- TrilogyAdapter: ignore `host` if `socket` parameter is set.
This allows to configure a connection on a UNIX socket via DATABASE_URL:
DATABASE_URL=trilogy://does-not-matter/my_db_production?socket=/var/run/mysql.sock
*Jean Boussier*
- Fix `has_secure_token` calls the setter method on initialize.
*Abeid Ahmed*
- Allow using `object_id` as a database column name.
It was available before rails 7.1 and may be used as a part of polymorphic relationship to `object` where `object` can be any other database record.
*Mikhail Doronin*
- Fix `rails db:create:all` to not touch databases before they are created.
*fatkodima*
#### Action View
- Better handle SyntaxError in Action View.
*Mario Caropreso*
- Fix `word_wrap` with empty string.
*Jonathan Hefner*
- Rename `ActionView::TestCase::Behavior::Content` to `ActionView::TestCase::Behavior::RenderedViewContent`.
Make `RenderedViewContent` inherit from `String`. Make private API with `:nodoc:`.
*Sean Doyle*
- Fix detection of required strict locals.
Further fix `render @collection` compatibility with strict locals
*Jean Boussier*
#### Action Pack
- Fix including `Rails.application.routes.url_helpers` directly in an
`ActiveSupport::Concern.`
*Jonathan Hefner*
- Fix system tests when using a Chrome binary that has been downloaded by
Selenium.
*Jonathan Hefner*
#### Active Job
- Do not trigger immediate loading of `ActiveJob::Base` when loading `ActiveJob::TestHelper`.
*Maxime Réty*
- Preserve the serialized timezone when deserializing `ActiveSupport::TimeWithZone` arguments.
*Joshua Young*
- Fix ActiveJob arguments serialization to correctly serialize String subclasses having custom serializers.
*fatkodima*
#### Action Mailer
- No changes.
#### Action Cable
- No changes.
#### Active Storage
- Fix N+1 query when fetching preview images for non-image assets.
*Aaron Patterson & Justin Searls*
- Fix all Active Storage database related models to respect
`ActiveRecord::Base.table_name_prefix` configuration.
*Chedli Bourguiba*
- Fix `ActiveStorage::Representations::ProxyController` not returning the proper
preview image variant for previewable files.
*Chedli Bourguiba*
- Fix `ActiveStorage::Representations::ProxyController` to proxy untracked
variants.
*Chedli Bourguiba*
- Fix direct upload forms when submit button contains nested elements.
*Marc Köhlbrugge*
- When using the `preprocessed: true` option, avoid enqueuing transform jobs
for blobs that are not representable.
*Chedli Bourguiba*
- Process preview image variant when calling `ActiveStorage::Preview#processed`.
For example, `attached_pdf.preview(:thumb).processed` will now immediately
generate the full-sized preview image and the `:thumb` variant of it.
Previously, the `:thumb` variant would not be generated until a further call
to e.g. `processed.url`.
*Chedli Bourguiba* and *Jonathan Hefner*
- Prevent `ActiveRecord::StrictLoadingViolationError` when strict loading is
enabled and the variant of an Active Storage preview has already been
processed (for example, by calling `ActiveStorage::Preview#url`).
*Jonathan Hefner*
- Fix `preprocessed: true` option for named variants of previewable files.
*Nico Wenterodt*
#### Action Mailbox
- No changes.
#### Action Text
- No changes.
#### Railties
- Make sure `config.after_routes_loaded` hook runs on boot.
*Rafael Mendonça França*
- Fix `config.log_level` not being respected when using a `BroadcastLogger`
*Édouard Chin*
- Fix isolated engines to take `ActiveRecord::Base.table_name_prefix` into consideration.
This will allow for engine defined models, such as inside Active Storage, to respect
Active Record table name prefix configuration.
*Chedli Bourguiba*
- The `bin/rails app:template` command will no longer add potentially unwanted
gem platforms via `bundle lock --add-platform=...` commands.
*Jonathan Hefner*

[Compare Source](https://togithub.com/rails/rails/compare/v7.1.1...v7.1.2)
##### Active Support
- Fix `:expires_in` option for `RedisCacheStore#write_multi`.
*fatkodima*
- Fix deserialization of non-string "purpose" field in Message serializer
*Jacopo Beschi*
- Prevent global cache options being overwritten when setting dynamic options
inside a `ActiveSupport::Cache::Store#fetch` block.
*Yasha Krasnou*
- Fix missing `require` resulting in `NoMethodError` when running
`bin/rails secrets:show` or `bin/rails secrets:edit`.
*Stephen Ierodiaconou*
- Ensure `{down,up}case_first` returns non-frozen string.
*Jonathan Hefner*
- Fix `#to_fs(:human_size)` to correctly work with negative numbers.
*Earlopain*
- Fix `BroadcastLogger#dup` so that it duplicates the logger's `broadcasts`.
*Andrew Novoselac*
- Fix issue where `bootstrap.rb` overwrites the `level` of a `BroadcastLogger`'s `broadcasts`.
*Andrew Novoselac*
- Fix `ActiveSupport::Cache` to handle outdated Marshal payload from Rails 6.1 format.
Active Support's Cache is supposed to treat a Marshal payload that can no longer be
deserialized as a cache miss. It fail to do so for compressed payload in the Rails 6.1
legacy format.
*Jean Boussier*
- Fix `OrderedOptions#dig` for array indexes.
*fatkodima*
- Fix time travel helpers to work when nested using with separate classes.
*fatkodima*
- Fix `delete_matched` for file cache store to work with keys longer than the
max filename size.
*fatkodima* and *Jonathan Hefner*
- Fix compatibility with the `semantic_logger` gem.
The `semantic_logger` gem doesn't behave exactly like stdlib logger in that
`SemanticLogger#level` returns a Symbol while stdlib `Logger#level` returns an Integer.
This caused the various `LogSubscriber` classes in Rails to break when assigned a
`SemanticLogger` instance.
*Jean Boussier*, *ojab*
##### Active Model
- Make `==(other)` method of AttributeSet safe.
*Dmitry Pogrebnoy*
##### Active Record
- Fix renaming primary key index when renaming a table with a UUID primary key
in PostgreSQL.
*fatkodima*
- Fix `where(field: values)` queries when `field` is a serialized attribute
(for example, when `field` uses `ActiveRecord::Base.serialize` or is a JSON
column).
*João Alves*
- Prevent marking broken connections as verified.
*Daniel Colson*
- Don't mark Float::INFINITY as changed when reassigning it
When saving a record with a float infinite value, it shouldn't mark as changed
*Maicol Bentancor*
- `ActiveRecord::Base.table_name` now returns `nil` instead of raising
"undefined method `abstract_class?` for Object:Class".
*a5-stable*
- Fix upserting for custom `:on_duplicate` and `:unique_by` consisting of all
inserts keys.
*fatkodima*
- Fixed an [issue](https://togithub.com/rails/rails/issues/49809) where saving a
record could innappropriately `dup` its attributes.
*Jonathan Hefner*
- Dump schema only for a specific db for rollback/up/down tasks for multiple dbs.
*fatkodima*
- Fix `NoMethodError` when casting a PostgreSQL `money` value that uses a
comma as its radix point and has no leading currency symbol. For example,
when casting `"3,50"`.
*Andreas Reischuck* and *Jonathan Hefner*
- Re-enable support for using `enum` with non-column-backed attributes.
Non-column-backed attributes must be previously declared with an explicit
type. For example:
```ruby
class Post < ActiveRecord::Base
attribute :topic, :string
enum topic: %i[science tech engineering math]
end
```
*Jonathan Hefner*
- Raise on `foreign_key:` being passed as an array in associations
*Nikita Vasilevsky*
- Return back maximum allowed PostgreSQL table name to 63 characters.
*fatkodima*
- Fix detecting `IDENTITY` columns for PostgreSQL < 10.
*fatkodima*
##### Action View
- Fix the `number_to_human_size` view helper to correctly work with negative numbers.
*Earlopain*
- Automatically discard the implicit locals injected by collection rendering for template that can't accept them
When rendering a collection, two implicit variables are injected, which breaks templates with strict locals.
Now they are only passed if the template will actually accept them.
*Yasha Krasnou*, *Jean Boussier*
- Fix `@rails/ujs` calling `start()` an extra time when using bundlers
*Hartley McGuire*, *Ryunosuke Sato*
- Fix the `capture` view helper compatibility with HAML and Slim
When a blank string was captured in HAML or Slim (and possibly other template engines)
it would instead return the entire buffer.
*Jean Boussier*
##### Action Pack
- Fix a race condition that could cause a `Text file busy - chromedriver`
error with parallel system tests
*Matt Brictson*
- Fix `StrongParameters#extract_value` to include blank values
Otherwise composite parameters may not be parsed correctly when one of the
component is blank.
*fatkodima*, *Yasha Krasnou*, *Matthias Eiglsperger*
- Add `racc` as a dependency since it will become a bundled gem in Ruby 3.4.0
*Hartley McGuire*
- Support handling Enumerator for non-buffered responses.
*Zachary Scott*

*Hartley McGuire*
- Fix using Trix with Sprockets
*Hartley McGuire*
##### Railties
- Fix running `db:system:change` when app has no Dockerfile.
*Hartley McGuire*
- If you accessed `config.eager_load_paths` and friends, later changes to
`config.paths` were not reflected in the expected auto/eager load paths.
Now, they are.
This bug has been latent since Rails 3.
Fixes [#49629](https://togithub.com/rails/rails/issues/49629).

### [`v7.1.1`](https://togithub.com/rails/rails/releases/tag/v7.1.1): 7.1.1
[Compare Source](https://togithub.com/rails/rails/compare/v7.1.0...v7.1.1)
#### Active Support
- Add support for keyword arguments when delegating calls to custom loggers from `ActiveSupport::BroadcastLogger`.
*Jenny Shen*
- `NumberHelper`: handle objects responding `to_d`.
*fatkodima*
- Fix RedisCacheStore to properly set the TTL when incrementing or decrementing.
This bug was only impacting Redis server older than 7.0.
*Thomas Countz*
- Fix MemoryStore to prevent race conditions when incrementing or decrementing.
*Pierre Jambet*
#### Active Model

*fatkodima*
- Fix "ArgumentError: wrong number of arguments (given 3, expected 2)" when
down migrating `rename_table` in older migrations.
*fatkodima*
- Do not require the Action Text, Active Storage and Action Mailbox tables
to be present when running when running test on CI.
*Rafael Mendonça França*
#### Action View
- Updated `@rails/ujs` files to ignore certain data-\* attributes when element is contenteditable.
This fix was already landed in >= 7.0.4.3, < 7.1.0.
\[[CVE-2023-23913](https://togithub.com/advisories/GHSA-xp5h-f8jf-rc8q)]

### [`v7.1.0`](https://togithub.com/rails/rails/releases/tag/v7.1.0): 7.1.0
[Compare Source](https://togithub.com/rails/rails/compare/v7.0.8...v7.1.0)
#### Active Support
- Fix `AS::MessagePack` with `ENV["RAILS_MAX_THREADS"]`.
*Jonathan Hefner*
- Add a new public API for broadcasting logs
This feature existed for a while but was until now a private API.
Broadcasting log allows to send log message to difference sinks (STDOUT, a file ...) and
is used by default in the development environment to write logs both on STDOUT and in the
"development.log" file.
Basic usage:
```ruby
stdout_logger = Logger.new(STDOUT)
file_logger = Logger.new("development.log")
broadcast = ActiveSupport::BroadcastLogger.new(stdout_logger, file_logger)
broadcast.info("Hello!") # The "Hello!" message is written on STDOUT and in the log file.
```
Adding other sink(s) to the broadcast:
```ruby
broadcast = ActiveSupport::BroadcastLogger.new
broadcast.broadcast_to(Logger.new(STDERR))
```
Remove a sink from the broadcast:
```ruby
stdout_logger = Logger.new(STDOUT)
broadcast = ActiveSupport::BroadcastLogger.new(stdout_logger)
broadcast.stop_broadcasting_to(stdout_logger)
```
*Edouard Chin*
- Fix Range#overlap? not taking empty ranges into account on Ruby < 3.3
*Nobuyoshi Nakada*, *Shouichi Kamiya*, *Hartley McGuire*
- Use Ruby 3.3 Range#overlap? if available
*Yasuo Honda*
- Add `bigdecimal` as Active Support dependency that is a bundled gem candidate for Ruby 3.4.
`bigdecimal` 3.1.4 or higher version will be installed.
Ruby 2.7 and 3.0 users who want `bigdecimal` version 2.0.0 or 3.0.0 behavior as a default gem,
pin the `bigdecimal` version in your application Gemfile.
*Koichi ITO*
- Add `drb`, `mutex_m` and `base64` that are bundled gem candidates for Ruby 3.4
*Yasuo Honda*
- When using cache format version >= 7.1 or a custom serializer, expired and
version-mismatched cache entries can now be detected without deserializing
their values.
*Jonathan Hefner*
- Make all cache stores return a boolean for `#delete`
Previously the `RedisCacheStore#delete` would return `1` if the entry
exists and `0` otherwise. Now it returns true if the entry exists and false
otherwise, just like the other stores.
The `FileStore` would return `nil` if the entry doesn't exists and returns
`false` now as well.
*Petrik de Heus*
- Active Support cache stores now support replacing the default compressor via
a `:compressor` option. The specified compressor must respond to `deflate`
and `inflate`. For example:
```ruby
module MyCompressor
def self.deflate(string)
```
### compression logic...
end
def self.inflate(compressed)
### decompression logic...
end
end
config.cache_store = :redis_cache_store, { compressor: MyCompressor }
```
*Jonathan Hefner*
- Active Support cache stores now support a `:serializer` option. Similar to
the `:coder` option, serializers must respond to `dump` and `load`. However,
serializers are only responsible for serializing a cached value, whereas
coders are responsible for serializing the entire `ActiveSupport::Cache::Entry`
instance. Additionally, the output from serializers can be automatically
compressed, whereas coders are responsible for their own compression.
Specifying a serializer instead of a coder also enables performance
optimizations, including the bare string optimization introduced by cache
format version 7.1.
The `:serializer` and `:coder` options are mutually exclusive. Specifying
both will raise an `ArgumentError`.
*Jonathan Hefner*
- Fix `ActiveSupport::Inflector.humanize(nil)` raising ``NoMethodError: undefined method `end_with?' for nil:NilClass``.
*James Robinson*
- Don't show secrets for `ActiveSupport::KeyGenerator#inspect`.
Before:
```ruby
ActiveSupport::KeyGenerator.new(secret).inspect
"#"
```
After:
```ruby
ActiveSupport::KeyGenerator::Aes256Gcm(secret).inspect
"#"
```
*Petrik de Heus*
- Improve error message when EventedFileUpdateChecker is used without a
compatible version of the Listen gem
*Hartley McGuire*
- Add `:report` behavior for Deprecation
Setting `config.active_support.deprecation = :report` uses the error
reporter to report deprecation warnings to `ActiveSupport::ErrorReporter`.
Deprecations are reported as handled errors, with a severity of `:warning`.
Useful to report deprecations happening in production to your bug tracker.
*Étienne Barrié*
- Rename `Range#overlaps?` to `#overlap?` and add alias for backwards compatibility
*Christian Schmidt*
- Fix `EncryptedConfiguration` returning incorrect values for some `Hash`
methods
*Hartley McGuire*
- Don't show secrets for `MessageEncryptor#inspect`.
Before:
```ruby
ActiveSupport::MessageEncryptor.new(secret, cipher: "aes-256-gcm").inspect
"#"
```
After:
```ruby
ActiveSupport::MessageEncryptor.new(secret, cipher: "aes-256-gcm").inspect
"#"
```
*Petrik de Heus*
- Don't show contents for `EncryptedConfiguration#inspect`.
Before:
```ruby
Rails.application.credentials.inspect
"#\"something secret\"} ... @key_file_contents=\"915e4ea054e011022398dc242\" ...>"
```
After:
```ruby
Rails.application.credentials.inspect
"#"
```
*Petrik de Heus*
- `ERB::Util.html_escape_once` always returns an `html_safe` string.
This method previously maintained the `html_safe?` property of a string on the return
value. Because this string has been escaped, however, not marking it as `html_safe` causes
entities to be double-escaped.
As an example, take this view snippet:
```html
<%= html_escape_once("this & that & the other") %>
```
Before this change, that would be double-escaped and render as:
```html
this & that & the other
```
After this change, it renders correctly as:
```html
this & that & the other
```
Fixes [#48256](https://togithub.com/rails/rails/issues/48256)
*Mike Dalessio*
- Deprecate `SafeBuffer#clone_empty`.
This method has not been used internally since Rails 4.2.0.
*Mike Dalessio*
- `MessageEncryptor`, `MessageVerifier`, and `config.active_support.message_serializer`
now accept `:message_pack` and `:message_pack_allow_marshal` as serializers.
These serializers require the [`msgpack` gem](https://rubygems.org/gems/msgpack)
(>= 1.7.0).
The Message Pack format can provide improved performance and smaller payload
sizes. It also supports round-tripping some Ruby types that are not supported
by JSON. For example:
```ruby
verifier = ActiveSupport::MessageVerifier.new("secret")
data = [{ a: 1 }, { b: 2 }.with_indifferent_access, 1.to_d, Time.at(0, 123)]
message = verifier.generate(data)
```
### BEFORE with config.active_support.message_serializer = :json
verifier.verified(message)
### => \[{"a"=>1}, {"b"=>2}, "1.0", "1969-12-31T18:00:00.000-06:00"]
verifier.verified(message).map(&:class)
### => \[Hash, Hash, String, String]
### AFTER with config.active_support.message_serializer = :message_pack
verifier.verified(message)
### => \[{:a=>1}, {"b"=>2}, 0.1e1, 1969-12-31 18:00:00.000123 -0600]
verifier.verified(message).map(&:class)
### => \[Hash, ActiveSupport::HashWithIndifferentAccess, BigDecimal, Time]
```
The `:message_pack` serializer can fall back to deserializing with
`ActiveSupport::JSON` when necessary, and the `:message_pack_allow_marshal`
serializer can fall back to deserializing with `Marshal` as well as
`ActiveSupport::JSON`. Additionally, the `:marshal`, `:json`, and
`:json_allow_marshal` serializers can now fall back to deserializing with
`ActiveSupport::MessagePack` when necessary. These behaviors ensure old
messages can still be read so that migration is easier.
*Jonathan Hefner*
- A new `7.1` cache format is available which includes an optimization for
bare string values such as view fragments.
The `7.1` cache format is used by default for new apps, and existing apps
can enable the format by setting `config.load_defaults 7.1` or by setting
`config.active_support.cache_format_version = 7.1` in `config/application.rb`
or a `config/environments/*.rb` file.
Cache entries written using the `6.1` or `7.0` cache formats can be read
when using the `7.1` format. To perform a rolling deploy of a Rails 7.1
upgrade, wherein servers that have not yet been upgraded must be able to
read caches from upgraded servers, leave the cache format unchanged on the
first deploy, then enable the `7.1` cache format on a subsequent deploy.
*Jonathan Hefner*
- Active Support cache stores can now use a preconfigured serializer based on
`ActiveSupport::MessagePack` via the `:serializer` option:
```ruby
config.cache_store = :redis_cache_store, { serializer: :message_pack }
```
The `:message_pack` serializer can reduce cache entry sizes and improve
performance, but requires the [`msgpack` gem](https://rubygems.org/gems/msgpack)
(>= 1.7.0).
The `:message_pack` serializer can read cache entries written by the default
serializer, and the default serializer can now read entries written by the
`:message_pack` serializer. These behaviors make it easy to migrate between
serializer without invalidating the entire cache.
*Jonathan Hefner*
- `Object#deep_dup` no longer duplicate named classes and modules.
Before:
```ruby
hash = { class: Object, module: Kernel }
hash.deep_dup # => {:class=>#, :module=>#}
```
After:
```ruby
hash = { class: Object, module: Kernel }
hash.deep_dup # => {:class=>Object, :module=>Kernel}
```
*Jean Boussier*
- Consistently raise an `ArgumentError` if the `ActiveSupport::Cache` key is blank.
*Joshua Young*
- Deprecate usage of the singleton `ActiveSupport::Deprecation`.
All usage of `ActiveSupport::Deprecation` as a singleton is deprecated, the most common one being
`ActiveSupport::Deprecation.warn`. Gem authors should now create their own deprecator (`ActiveSupport::Deprecation`
object), and use it to emit deprecation warnings.
Calling any of the following without specifying a deprecator argument is also deprecated:
- Module.deprecate
- deprecate_constant
- DeprecatedObjectProxy
- DeprecatedInstanceVariableProxy
- DeprecatedConstantProxy
- deprecation-related test assertions
Use of `ActiveSupport::Deprecation.silence` and configuration methods like `behavior=`, `disallowed_behavior=`,
`disallowed_warnings=` should now be aimed at the [application's deprecators](https://api.rubyonrails.org/classes/Rails/Application.html#method-i-deprecators).
```ruby
Rails.application.deprecators.silence do
```
### code that emits deprecation warnings
end
```
If your gem has a Railtie or Engine, it's encouraged to add your deprecator to the application's deprecators, that
way the deprecation related configuration options will apply to it as well, e.g.
`config.active_support.report_deprecations` set to `false` in the production environment will also disable your
deprecator.
```ruby
initializer "my_gem.deprecator" do |app|
app.deprecators[:my_gem] = MyGem.deprecator
end
```
*Étienne Barrié*
- Add `Object#with` to set and restore public attributes around a block

- Remove deprecated option to passing a format to `#to_s` in `Array`, `Range`, `Date`, `DateTime`, `Time`,
`BigDecimal`, `Float` and, `Integer`.
*Rafael Mendonça França*
- Remove deprecated `ActiveSupport::PerThreadRegistry`.
*Rafael Mendonça França*
- Remove deprecated override of `Enumerable#sum`.
*Rafael Mendonça França*
- Deprecated initializing a `ActiveSupport::Cache::MemCacheStore` with an instance of `Dalli::Client`.
Deprecate the undocumented option of providing an already-initialized instance of `Dalli::Client` to `ActiveSupport::Cache::MemCacheStore`. Such clients could be configured with unrecognized options, which could lead to unexpected behavior. Instead, provide addresses as documented.
*aledustet*
- Stub `Time.new()` in `TimeHelpers#travel_to`
```ruby
travel_to Time.new(2004, 11, 24) do
```
### Inside the `travel_to` block `Time.new` is stubbed
assert_equal 2004, Time.new.year
end
```
*fatkodima*
- Raise `ActiveSupport::MessageEncryptor::InvalidMessage` from
`ActiveSupport::MessageEncryptor#decrypt_and_verify` regardless of cipher.
Previously, when a `MessageEncryptor` was using a non-AEAD cipher such as
AES-256-CBC, a corrupt or tampered message would raise
`ActiveSupport::MessageVerifier::InvalidSignature`. Now, all ciphers raise
the same error:
```ruby
encryptor = ActiveSupport::MessageEncryptor.new("x" * 32, cipher: "aes-256-gcm")
message = encryptor.encrypt_and_sign("message")
encryptor.decrypt_and_verify(message.next)
```
### => raises ActiveSupport::MessageEncryptor::InvalidMessage
encryptor = ActiveSupport::MessageEncryptor.new("x" * 32, cipher: "aes-256-cbc")
message = encryptor.encrypt_and_sign("message")
encryptor.decrypt_and_verify(message.next)
### BEFORE:
### => raises ActiveSupport::MessageVerifier::InvalidSignature
### AFTER:
### => raises ActiveSupport::MessageEncryptor::InvalidMessage
```
*Jonathan Hefner*
- Support `nil` original values when using `ActiveSupport::MessageVerifier#verify`.
Previously, `MessageVerifier#verify` did not work with `nil` original
values, though both `MessageVerifier#verified` and
`MessageEncryptor#decrypt_and_verify` do:
```ruby
encryptor = ActiveSupport::MessageEncryptor.new(secret)
message = encryptor.encrypt_and_sign(nil)
encryptor.decrypt_and_verify(message)
```
### => nil
verifier = ActiveSupport::MessageVerifier.new(secret)
message = verifier.generate(nil)
verifier.verified(message)
### => nil
verifier.verify(message)
### BEFORE:
### => raises ActiveSupport::MessageVerifier::InvalidSignature
### AFTER:
### => nil
```
*Jonathan Hefner*
- Maintain `html_safe?` on html_safe strings when sliced with `slice`, `slice!`, or `chr` method.
Previously, `html_safe?` was only maintained when the html_safe strings were sliced
with `[]` method. Now, `slice`, `slice!`, and `chr` methods will maintain `html_safe?` like `[]` method.
```ruby
string = "
test
".html_safe
string.slice(0, 1).html_safe? # => true
string.slice!(0, 1).html_safe? # => true
```
### maintain html_safe? after the slice!
string.html_safe? # => true
string.chr.html_safe? # => true
```
*Michael Go*
- Add `Object#in?` support for open ranges.
```ruby
assert Date.today.in?(..Date.tomorrow)
assert_not Date.today.in?(Date.tomorrow..)
```
*Ignacio Galindo*
- `config.i18n.raise_on_missing_translations = true` now raises on any missing translation.
Previously it would only raise when called in a view or controller. Now it will raise
anytime `I18n.t` is provided an unrecognised key.
If you do not want this behaviour, you can customise the i18n exception handler. See the
upgrading guide or i18n guide for more information.
*Alex Ghiculescu*
- `ActiveSupport::CurrentAttributes` now raises if a restricted attribute name is used.
Attributes such as `set` and `reset` cannot be used as they clash with the
`CurrentAttributes` public API.
*Alex Ghiculescu*
- `HashWithIndifferentAccess#transform_keys` now takes a Hash argument, just
as Ruby's `Hash#transform_keys` does.
*Akira Matsuda*
- `delegate` now defines method with proper arity when delegating to a Class.
With this change, it defines faster method (3.5x faster with no argument).
However, in order to gain this benefit, the delegation target method has to
be defined before declaring the delegation.
```ruby
```
### This defines 3.5 times faster method than before
class C
def self.x() end
delegate :x, to: :class
end
class C
### This works but silently falls back to old behavior because
### `delegate` cannot find the definition of `x`
delegate :x, to: :class
def self.x() end
end
```
*Akira Matsuda*
- `assert_difference` message now includes what changed.
This makes it easier to debug non-obvious failures.
Before:
"User.count" didn't change by 32.
Expected: 1611
Actual: 1579
After:
"User.count" didn't change by 32, but by 0.
Expected: 1611
Actual: 1579
*Alex Ghiculescu*
- Add ability to match exception messages to `assert_raises` assertion
Instead of this
```ruby
error = assert_raises(ArgumentError) do
perform_service(param: 'exception')
end
assert_match(/incorrect param/i, error.message)
```
you can now write this
```ruby
assert_raises(ArgumentError, match: /incorrect param/i) do
perform_service(param: 'exception')
end
```
*fatkodima*
- Add `Rails.env.local?` shorthand for `Rails.env.development? || Rails.env.test?`.
*DHH*
- `ActiveSupport::Testing::TimeHelpers` now accepts named `with_usec` argument
to `freeze_time`, `travel`, and `travel_to` methods. Passing true prevents
truncating the destination time with `change(usec: 0)`.
*KevSlashNull*, and *serprex*
- `ActiveSupport::CurrentAttributes.resets` now accepts a method name
The block API is still the recommended approach, but now both APIs are supported:
```ruby
class Current < ActiveSupport::CurrentAttributes
resets { Time.zone = nil }
resets :clear_time_zone
end
```
*Alex Ghiculescu*
- Ensure `ActiveSupport::Testing::Isolation::Forking` closes pipes
Previously, `Forking.run_in_isolation` opened two ends of a pipe. The fork
process closed the read end, wrote to it, and then terminated (which
presumably closed the file descriptors on its end). The parent process
closed the write end, read from it, and returned, never closing the read
end.
This resulted in an accumulation of open file descriptors, which could
cause errors if the limit is reached.
*Sam Bostock*
- Fix `Time#change` and `Time#advance` for times around the end of Daylight
Saving Time.
Previously, when `Time#change` or `Time#advance` constructed a time inside
the final stretch of Daylight Saving Time (DST), the non-DST offset would
always be chosen for local times:
```ruby
```
### DST ended just before 2021-11-07 2:00:00 AM in US/Eastern.
ENV["TZ"] = "US/Eastern"
time = Time.local(2021, 11, 07, 00, 59, 59) + 1
### => 2021-11-07 01:00:00 -0400
time.change(day: 07)
### => 2021-11-07 01:00:00 -0500
time.advance(seconds: 0)
### => 2021-11-07 01:00:00 -0500
time = Time.local(2021, 11, 06, 01, 00, 00)
### => 2021-11-06 01:00:00 -0400
time.change(day: 07)
### => 2021-11-07 01:00:00 -0500
time.advance(days: 1)
### => 2021-11-07 01:00:00 -0500
```
And the DST offset would always be chosen for times with a `TimeZone`
object:
```ruby
Time.zone = "US/Eastern"
time = Time.new(2021, 11, 07, 02, 00, 00, Time.zone) - 3600
### => 2021-11-07 01:00:00 -0500
time.change(day: 07)
### => 2021-11-07 01:00:00 -0400
time.advance(seconds: 0)
### => 2021-11-07 01:00:00 -0400
time = Time.new(2021, 11, 8, 01, 00, 00, Time.zone)
### => 2021-11-08 01:00:00 -0500
time.change(day: 07)
### => 2021-11-07 01:00:00 -0400
time.advance(days: -1)
### => 2021-11-07 01:00:00 -0400
```
Now, `Time#change` and `Time#advance` will choose the offset that matches
the original time's offset when possible:
```ruby
ENV["TZ"] = "US/Eastern"
time = Time.local(2021, 11, 07, 00, 59, 59) + 1
### => 2021-11-07 01:00:00 -0400
time.change(day: 07)
### => 2021-11-07 01:00:00 -0400
time.advance(seconds: 0)
### => 2021-11-07 01:00:00 -0400
time = Time.local(2021, 11, 06, 01, 00, 00)
### => 2021-11-06 01:00:00 -0400
time.change(day: 07)
### => 2021-11-07 01:00:00 -0400
time.advance(days: 1)
### => 2021-11-07 01:00:00 -0400
Time.zone = "US/Eastern"
time = Time.new(2021, 11, 07, 02, 00, 00, Time.zone) - 3600
### => 2021-11-07 01:00:00 -0500
time.change(day: 07)
### => 2021-11-07 01:00:00 -0500
time.advance(seconds: 0)
### => 2021-11-07 01:00:00 -0500
time = Time.new(2021, 11, 8, 01, 00, 00, Time.zone)
### => 2021-11-08 01:00:00 -0500
time.change(day: 07)
### => 2021-11-07 01:00:00 -0500
time.advance(days: -1)
### => 2021-11-07 01:00:00 -0500
```
*Kevin Hall*, *Takayoshi Nishida*, and *Jonathan Hefner*
- Fix MemoryStore to preserve entries TTL when incrementing or decrementing
This is to be more consistent with how MemCachedStore and RedisCacheStore behaves.
*Jean Boussier*
- `Rails.error.handle` and `Rails.error.record` filter now by multiple error classes.
```ruby
Rails.error.handle(IOError, ArgumentError) do
1 + '1' # raises TypeError
end
1 + 1 # TypeErrors are not IOErrors or ArgumentError, so this will *not* be handled
```
*Martin Spickermann*
- `Class#subclasses` and `Class#descendants` now automatically filter reloaded classes.
Previously they could return old implementations of reloadable classes that have been
dereferenced but not yet garbage collected.
They now automatically filter such classes like `DescendantTracker#subclasses` and
`DescendantTracker#descendants`.
*Jean Boussier*
- `Rails.error.report` now marks errors as reported to avoid reporting them twice.
In some cases, users might want to report errors explicitly with some extra context
before letting it bubble up.
This also allows to safely catch and report errors outside of the execution context.
*Jean Boussier*
- Add `assert_error_reported` and `assert_no_error_reported`
Allows to easily asserts an error happened but was handled
```ruby
report = assert_error_reported(IOError) do
```
### ...
end
assert_equal "Oops", report.error.message
assert_equal "admin", report.context[:section]
assert_equal :warning, report.severity
assert_predicate report, :handled?
```
*Jean Boussier*
- `ActiveSupport::Deprecation` behavior callbacks can now receive the
deprecator instance as an argument. This makes it easier for such callbacks
to change their behavior based on the deprecator's state. For example,
based on the deprecator's `debug` flag.
3-arity and splat-args callbacks such as the following will now be passed
the deprecator instance as their third argument:
- `->(message, callstack, deprecator) { ... }`
- `->(*args) { ... }`
- `->(message, *other_args) { ... }`
2-arity and 4-arity callbacks such as the following will continue to behave
the same as before:
- `->(message, callstack) { ... }`
- `->(message, callstack, deprecation_horizon, gem_name) { ... }`
- `->(message, callstack, *deprecation_details) { ... }`
*Jonathan Hefner*
- `ActiveSupport::Deprecation#disallowed_warnings` now affects the instance on
which it is configured.
This means that individual `ActiveSupport::Deprecation` instances can be
configured with their own disallowed warnings, and the global
`ActiveSupport::Deprecation.disallowed_warnings` now only affects the global
`ActiveSupport::Deprecation.warn`.
**Before**
```ruby
ActiveSupport::Deprecation.disallowed_warnings = ["foo"]
deprecator = ActiveSupport::Deprecation.new("2.0", "MyCoolGem")
deprecator.disallowed_warnings = ["bar"]
ActiveSupport::Deprecation.warn("foo") # => raise ActiveSupport::DeprecationException
ActiveSupport::Deprecation.warn("bar") # => print "DEPRECATION WARNING: bar"
deprecator.warn("foo") # => raise ActiveSupport::DeprecationException
deprecator.warn("bar") # => print "DEPRECATION WARNING: bar"
```
**After**
```ruby
ActiveSupport::Deprecation.disallowed_warnings = ["foo"]
deprecator = ActiveSupport::Deprecation.new("2.0", "MyCoolGem")
deprecator.disallowed_warnings = ["bar"]
ActiveSupport::Deprecation.warn("foo") # => raise ActiveSupport::DeprecationException
ActiveSupport::Deprecation.warn("bar") # => print "DEPRECATION WARNING: bar"
deprecator.warn("foo") # => print "DEPRECATION WARNING: foo"
deprecator.warn("bar") # => raise ActiveSupport::DeprecationException
```
Note that global `ActiveSupport::Deprecation` methods such as `ActiveSupport::Deprecation.warn`
and `ActiveSupport::Deprecation.disallowed_warnings` have been deprecated.
*Jonathan Hefner*
- Add italic and underline support to `ActiveSupport::LogSubscriber#color`
Previously, only bold text was supported via a positional argument.
This allows for bold, italic, and underline options to be specified
for colored logs.
```ruby
info color("Hello world!", :red, bold: true, underline: true)
```
*Gannon McGibbon*
- Add `String#downcase_first` method.
This method is the corollary of `String#upcase_first`.
*Mark Schneider*
- `thread_mattr_accessor` will call `.dup.freeze` on non-frozen default values.
This provides a basic level of protection against different threads trying
to mutate a shared default object.
*Jonathan Hefner*
- Add `raise_on_invalid_cache_expiration_time` config to `ActiveSupport::Cache::Store`
Specifies if an `ArgumentError` should be raised if `Rails.cache` `fetch` or
`write` are given an invalid `expires_at` or `expires_in` time.
Options are `true`, and `false`. If `false`, the exception will be reported
as `handled` and logged instead. Defaults to `true` if `config.load_defaults >= 7.1`.
*Trevor Turk*
- `ActiveSupport::Cache:Store#fetch` now passes an options accessor to the block.
It makes possible to override cache options:
Rails.cache.fetch("3rd-party-token") do |name, options|
token = fetch_token_from_remote
### set cache's TTL to match token's TTL
options.expires_in = token.expires_in
token
end
*Andrii Gladkyi*, *Jean Boussier*
- `default` option of `thread_mattr_accessor` now applies through inheritance and
also across new threads.
Previously, the `default` value provided was set only at the moment of defining
the attribute writer, which would cause the attribute to be uninitialized in
descendants and in other threads.
Fixes [#43312](https://togithub.com/rails/rails/issues/43312).
*Thierry Deo*
- Redis cache store is now compatible with redis-rb 5.0.
*Jean Boussier*
- Add `skip_nil:` support to `ActiveSupport::Cache::Store#fetch_multi`.
*Daniel Alfaro*
- Add `quarter` method to date/time
*Matt Swanson*
- Fix `NoMethodError` on custom `ActiveSupport::Deprecation` behavior.
`ActiveSupport::Deprecation.behavior=` was supposed to accept any object
that responds to `call`, but in fact its internal implementation assumed that
this object could respond to `arity`, so it was restricted to only `Proc` objects.
This change removes this `arity` restriction of custom behaviors.
*Ryo Nakamura*
- Support `:url_safe` option for `MessageEncryptor`.
The `MessageEncryptor` constructor now accepts a `:url_safe` option, similar
to the `MessageVerifier` constructor. When enabled, this option ensures
that messages use a URL-safe encoding.
*Jonathan Hefner*
- Add `url_safe` option to `ActiveSupport::MessageVerifier` initializer
`ActiveSupport::MessageVerifier.new` now takes optional `url_safe` argument.
It can generate URL-safe strings by passing `url_safe: true`.
```ruby
verifier = ActiveSupport::MessageVerifier.new(url_safe: true)
message = verifier.generate(data) # => URL-safe string
```
This option is `false` by default to be backwards compatible.
*Shouichi Kamiya*
- Enable connection pooling by default for `MemCacheStore` and `RedisCacheStore`.
If you want to disable connection pooling, set `:pool` option to `false` when configuring the cache store:
```ruby
config.cache_store = :mem_cache_store, "cache.example.com", pool: false
```
*fatkodima*
- Add `force:` support to `ActiveSupport::Cache::Store#fetch_multi`.
*fatkodima*
- Deprecated `:pool_size` and `:pool_timeout` options for configuring connection pooling in cache stores.
Use `pool: true` to enable pooling with default settings:
```ruby
config.cache_store = :redis_cache_store, pool: true
```
Or pass individual options via `:pool` option:
```ruby
config.cache_store = :redis_cache_store, pool: { size: 10, timeout: 2 }
```
*fatkodima*
- Allow #increment and #decrement methods of `ActiveSupport::Cache::Store`
subclasses to set new values.
Previously incrementing or decrementing an unset key would fail and return
nil. A default will now be assumed and the key will be created.
*Andrej Blagojević*, *Eugene Kenny*
- Add `skip_nil:` support to `RedisCacheStore`
*Joey Paris*
- `ActiveSupport::Cache::MemoryStore#write(name, val, unless_exist:true)` now
correctly writes expired keys.
*Alan Savage*
- `ActiveSupport::ErrorReporter` now accepts and forward a `source:` parameter.
This allow libraries to signal the origin of the errors, and reporters
to easily ignore some sources.
*Jean Boussier*
- Fix and add protections for XSS in `ActionView::Helpers` and `ERB::Util`.
Add the method `ERB::Util.xml_name_escape` to escape dangerous characters
in names of tags and names of attributes, following the specification of XML.
*Álvaro Martín Fraguas*
- Respect `ActiveSupport::Logger.new`'s `:formatter` keyword argument
The stdlib `Logger::new` allows passing a `:formatter` keyword argument to
set the logger's formatter. Previously `ActiveSupport::Logger.new` ignored
that argument by always setting the formatter to an instance of
`ActiveSupport::Logger::SimpleFormatter`.
*Steven Harman*
- Deprecate preserving the pre-Ruby 2.4 behavior of `to_time`
With Ruby 2.4+ the default for +to_time+ changed from converting to the
local system time to preserving the offset of the receiver. At the time Rails
supported older versions of Ruby so a compatibility layer was added to assist
in the migration process. From Rails 5.0 new applications have defaulted to
the Ruby 2.4+ behavior and since Rails 7.0 now only supports Ruby 2.7+
this compatibility layer can be safely removed.
To minimize any noise generated the deprecation warning only appears when the
setting is configured to `false` as that is the only scenario where the
removal of the compatibility layer has any effect.
*Andrew White*
- `Pathname.blank?` only returns true for `Pathname.new("")`
Previously it would end up calling `Pathname#empty?` which returned true
if the path existed and was an empty directory or file.
That behavior was unlikely to be expected.
*Jean Boussier*
- Deprecate `Notification::Event`'s `#children` and `#parent_of?`
*John Hawthorn*
- Change the default serializer of `ActiveSupport::MessageVerifier` from
`Marshal` to `ActiveSupport::JSON` when using `config.load_defaults 7.1`.
Messages serialized with `Marshal` can still be read, but new messages will
be serialized with `ActiveSupport::JSON`. For more information, see
https://guides.rubyonrails.org/v7.1/configuring.html#config-active-support-message-serializer.
*Saba Kiaei*, *David Buckley*, and *Jonathan Hefner*
- Change the default serializer of `ActiveSupport::MessageEncryptor` from
`Marshal` to `ActiveSupport::JSON` when using `config.load_defaults 7.1`.
Messages serialized with `Marshal` can still be read, but new messages will
be serialized with `ActiveSupport::JSON`. For more information, see
https://guides.rubyonrails.org/v7.1/configuring.html#config-active-support-message-serializer.
*Zack Deveau*, *Martin Gingras*, and *Jonathan Hefner*
- Add `ActiveSupport::TestCase#stub_const` to stub a constant for the duration of a yield.
*DHH*
- Fix `ActiveSupport::EncryptedConfiguration` to be compatible with Psych 4
*Stephen Sugden*
- Improve `File.atomic_write` error handling
*Daniel Pepper*
- Fix `Class#descendants` and `DescendantsTracker#descendants` compatibility with Ruby 3.1.
[The native `Class#descendants` was reverted prior to Ruby 3.1 release](https://bugs.ruby-lang.org/issues/14394#note-33),
but `Class#subclasses` was kept, breaking the feature detection.
*Jean Boussier*
#### Active Model
- Remove change in the typography of user facing error messages.
For example, “can’t be blank” is again “can't be blank”.
*Rafael Mendonça França*
- Support composite identifiers in `to_key`
`to_key` avoids wrapping `#id` value into an `Array` if `#id` already an array
*Nikita Vasilevsky*
- Add `ActiveModel::Conversion.param_delimiter` to configure delimiter being used in `to_param`
*Nikita Vasilevsky*
- `undefine_attribute_methods` undefines alias attribute methods along with attribute methods.
*Nikita Vasilevsky*
- Error.full_message now strips ":base" from the message.
*zzak*
- Add a load hook for `ActiveModel::Model` (named `active_model`) to match the load hook for
`ActiveRecord::Base` and allow for overriding aspects of the `ActiveModel::Model` class.
*Lewis Buckley*
- Improve password length validation in ActiveModel::SecurePassword to consider byte size for BCrypt
compatibility.
The previous password length validation only considered the character count, which may not
accurately reflect the 72-byte size limit imposed by BCrypt. This change updates the validation
to consider both character count and byte size while keeping the character length validation in place.
```ruby
user = User.new(password: "a" * 73) # 73 characters
user.valid? # => false
user.errors[:password] # => ["is too long"]
user = User.new(password: "あ" * 25) # 25 characters, 75 bytes
user.valid? # => false
user.errors[:password] # => ["is too long"]
```
*ChatGPT*, *Guillermo Iguaran*
- `has_secure_password` now generates an `#{attribute}_salt` method that returns the salt
used to compute the password digest. The salt will change whenever the password is changed,
so it can be used to create single-use password reset tokens with `generates_token_for`:
```ruby
class User < ActiveRecord::Base
has_secure_password
generates_token_for :password_reset, expires_in: 15.minutes do
password_salt&.last(10)
end
end
```
*Lázaro Nixon*
- Improve typography of user facing error messages. In English contractions,
the Unicode APOSTROPHE (`U+0027`) is now RIGHT SINGLE QUOTATION MARK
(`U+2019`). For example, "can't be blank" is now "can’t be blank".
*Jon Dufresne*
- Add class to `ActiveModel::MissingAttributeError` error message.
Show which class is missing the attribute in the error message:
```ruby
user = User.first
user.pets.select(:id).first.user_id
```
### => ActiveModel::MissingAttributeError: missing attribute 'user_id' for Pet
```
*Petrik de Heus*
- Raise `NoMethodError` in `ActiveModel::Type::Value#as_json` to avoid unpredictable
results.
*Vasiliy Ermolovich*
- Custom attribute types that inherit from Active Model built-in types and do
not override the `serialize` method will now benefit from an optimization
when serializing attribute values for the database.
For example, with a custom type like the following:
```ruby
class DowncasedString < ActiveModel::Type::String
def cast(value)
super&.downcase
end
end
ActiveRecord::Type.register(:downcased_string, DowncasedString)
class User < ActiveRecord::Base
attribute :email, :downcased_string
end
user = User.new(email: "FooBar@example.com")
```
Serializing the `email` attribute for the database will be roughly twice as
fast. More expensive `cast` operations will likely see greater improvements.
*Jonathan Hefner*
- `has_secure_password` now supports password challenges via a
`password_challenge` accessor and validation.
A password challenge is a safeguard to verify that the current user is
actually the password owner. It can be used when changing sensitive model
fields, such as the password itself. It is different than a password
confirmation, which is used to prevent password typos.
When `password_challenge` is set, the validation checks that the value's
digest matches the *currently persisted* `password_digest` (i.e.
`password_digest_was`).
This allows a password challenge to be done as part of a typical `update`
call, just like a password confirmation. It also allows a password
challenge error to be handled in the same way as other validation errors.
For example, in the controller, instead of:
```ruby
password_params = params.require(:password).permit(
:password_challenge,
:password,
:password_confirmation,
)
password_challenge = password_params.delete(:password_challenge)
@password_challenge_failed = !current_user.authenticate(password_challenge)
if !@password_challenge_failed && current_user.update(password_params)
```
### ...
end
```
You can now write:
```ruby
password_params = params.require(:password).permit(
:password_challenge,
:password,
:password_confirmation,
).with_defaults(password_challenge: "")
if current_user.update(password_params)
### ...
end
```
And, in the view, instead of checking `@password_challenge_failed`, you can
render an error for the `password_challenge` field just as you would for
other form fields, including utilizing `config.action_view.field_error_proc`.
*Jonathan Hefner*
- Support infinite ranges for `LengthValidator`s `:in`/`:within` options
```ruby
validates_length_of :first_name, in: ..30
```
*fatkodima*
- Add support for beginless ranges to inclusivity/exclusivity validators:
```ruby
validates_inclusion_of :birth_date, in: -> { (..Date.today) }

*fatkodima*
- Fix casting long strings to `Date`, `Time` or `DateTime`
*fatkodima*
- Use different cache namespace for proxy calls
Models can currently have different attribute bodies for the same method
names, leading to conflicts. Adding a new namespace `:active_model_proxy`
fixes the issue.
*Chris Salzberg*
#### Active Record
- Remove -shm and -wal SQLite files when `rails db:drop` is run.

### [`v7.2.100`](https://togithub.com/rails/rails/compare/v7.2.0...a11f0a63673d274c59c69c2688c63ba303b86193) [Compare Source](https://togithub.com/rails/rails/compare/v7.2.0...a11f0a63673d274c59c69c2688c63ba303b86193) ### [`v7.2.0`](https://togithub.com/rails/rails/compare/v7.1.3.4...v7.2.0) [Compare Source](https://togithub.com/rails/rails/compare/6f57590388ca38ed2b83bc1207a8be13a9ba2aef...v7.2.0) ### [`v7.1.400`](https://togithub.com/rails/rails/compare/v7.1.3...6f57590388ca38ed2b83bc1207a8be13a9ba2aef) [Compare Source](https://togithub.com/rails/rails/compare/v7.1.3...6f57590388ca38ed2b83bc1207a8be13a9ba2aef) ### [`v7.1.3`](https://togithub.com/rails/rails/releases/tag/v7.1.3): 7.1.3 [Compare Source](https://togithub.com/rails/rails/compare/v7.1.2...v7.1.3) #### Active Support - Handle nil `backtrace_locations` in `ActiveSupport::SyntaxErrorProxy`. *Eugene Kenny* - Fix `ActiveSupport::JSON.encode` to prevent duplicate keys. If the same key exist in both String and Symbol form it could lead to the same key being emitted twice. *Manish Sharma* - Fix `ActiveSupport::Cache::Store#read_multi` when using a cache namespace and local cache strategy. *Mark Oleson* - Fix `Time.now/DateTime.now/Date.today` to return results in a system timezone after `#travel_to`. There is a bug in the current implementation of #travel_to: it remembers a timezone of its argument, and all stubbed methods start returning results in that remembered timezone. However, the expected behaviour is to return results in a system timezone. *Aleksei Chernenkov* - Fix `:unless_exist` option for `MemoryStore#write` (et al) when using a cache namespace. *S. Brent Faulkner* - Fix ActiveSupport::Deprecation to handle blaming generated code. *Jean Boussier*, *fatkodima* #### Active Model - No changes. #### Active Record - Fix Migrations with versions older than 7.1 validating options given to `add_reference`. *Hartley McGuire* - Ensure `reload` sets correct owner for each association. *Dmytro Savochkin* - Fix view runtime for controllers with async queries. *fatkodima* - Fix `load_async` to work with query cache. *fatkodima* - Fix polymorphic `belongs_to` to correctly use parent's `query_constraints`. *fatkodima* - Fix `Preloader` to not generate a query for already loaded association with `query_constraints`. *fatkodima* - Fix multi-database polymorphic preloading with equivalent table names. When preloading polymorphic associations, if two models pointed to two tables with the same name but located in different databases, the preloader would only load one. *Ari Summer* - Fix `encrypted_attribute?` to take into account context properties passed to `encrypts`. *Maxime Réty* - Fix `find_by` to work correctly in presence of composite primary keys. *fatkodima* - Fix async queries sometimes returning a raw result if they hit the query cache. `ShipPart.async_count` could return a raw integer rather than a Promise if it found the result in the query cache. *fatkodima* - Fix `Relation#transaction` to not apply a default scope. The method was incorrectly setting a default scope around its block: ```ruby Post.where(published: true).transaction do Post.count # SELECT COUNT(*) FROM posts WHERE published = FALSE; end ``` *Jean Boussier* - Fix calling `async_pluck` on a `none` relation. `Model.none.async_pluck(:id)` was returning a naked value instead of a promise. *Jean Boussier* - Fix calling `load_async` on a `none` relation. `Model.none.load_async` was returning a broken result. *Lucas Mazza* - TrilogyAdapter: ignore `host` if `socket` parameter is set. This allows to configure a connection on a UNIX socket via DATABASE_URL: DATABASE_URL=trilogy://does-not-matter/my_db_production?socket=/var/run/mysql.sock *Jean Boussier* - Fix `has_secure_token` calls the setter method on initialize. *Abeid Ahmed* - Allow using `object_id` as a database column name. It was available before rails 7.1 and may be used as a part of polymorphic relationship to `object` where `object` can be any other database record. *Mikhail Doronin* - Fix `rails db:create:all` to not touch databases before they are created. *fatkodima* #### Action View - Better handle SyntaxError in Action View. *Mario Caropreso* - Fix `word_wrap` with empty string. *Jonathan Hefner* - Rename `ActionView::TestCase::Behavior::Content` to `ActionView::TestCase::Behavior::RenderedViewContent`. Make `RenderedViewContent` inherit from `String`. Make private API with `:nodoc:`. *Sean Doyle* - Fix detection of required strict locals. Further fix `render @collection` compatibility with strict locals *Jean Boussier* #### Action Pack - Fix including `Rails.application.routes.url_helpers` directly in an `ActiveSupport::Concern.` *Jonathan Hefner* - Fix system tests when using a Chrome binary that has been downloaded by Selenium. *Jonathan Hefner* #### Active Job - Do not trigger immediate loading of `ActiveJob::Base` when loading `ActiveJob::TestHelper`. *Maxime Réty* - Preserve the serialized timezone when deserializing `ActiveSupport::TimeWithZone` arguments. *Joshua Young* - Fix ActiveJob arguments serialization to correctly serialize String subclasses having custom serializers. *fatkodima* #### Action Mailer - No changes. #### Action Cable - No changes. #### Active Storage - Fix N+1 query when fetching preview images for non-image assets. *Aaron Patterson & Justin Searls* - Fix all Active Storage database related models to respect `ActiveRecord::Base.table_name_prefix` configuration. *Chedli Bourguiba* - Fix `ActiveStorage::Representations::ProxyController` not returning the proper preview image variant for previewable files. *Chedli Bourguiba* - Fix `ActiveStorage::Representations::ProxyController` to proxy untracked variants. *Chedli Bourguiba* - Fix direct upload forms when submit button contains nested elements. *Marc Köhlbrugge* - When using the `preprocessed: true` option, avoid enqueuing transform jobs for blobs that are not representable. *Chedli Bourguiba* - Process preview image variant when calling `ActiveStorage::Preview#processed`. For example, `attached_pdf.preview(:thumb).processed` will now immediately generate the full-sized preview image and the `:thumb` variant of it. Previously, the `:thumb` variant would not be generated until a further call to e.g. `processed.url`. *Chedli Bourguiba* and *Jonathan Hefner* - Prevent `ActiveRecord::StrictLoadingViolationError` when strict loading is enabled and the variant of an Active Storage preview has already been processed (for example, by calling `ActiveStorage::Preview#url`). *Jonathan Hefner* - Fix `preprocessed: true` option for named variants of previewable files. *Nico Wenterodt* #### Action Mailbox - No changes. #### Action Text - No changes. #### Railties - Make sure `config.after_routes_loaded` hook runs on boot. *Rafael Mendonça França* - Fix `config.log_level` not being respected when using a `BroadcastLogger` *Édouard Chin* - Fix isolated engines to take `ActiveRecord::Base.table_name_prefix` into consideration. This will allow for engine defined models, such as inside Active Storage, to respect Active Record table name prefix configuration. *Chedli Bourguiba* - The `bin/rails app:template` command will no longer add potentially unwanted gem platforms via `bundle lock --add-platform=...` commands. *Jonathan Hefner* ### [`v7.1.2`](https://togithub.com/rails/rails/releases/tag/v7.1.2): 7.1.2 [Compare Source](https://togithub.com/rails/rails/compare/v7.1.1...v7.1.2) ##### Active Support - Fix `:expires_in` option for `RedisCacheStore#write_multi`. *fatkodima* - Fix deserialization of non-string "purpose" field in Message serializer *Jacopo Beschi* - Prevent global cache options being overwritten when setting dynamic options inside a `ActiveSupport::Cache::Store#fetch` block. *Yasha Krasnou* - Fix missing `require` resulting in `NoMethodError` when running `bin/rails secrets:show` or `bin/rails secrets:edit`. *Stephen Ierodiaconou* - Ensure `{down,up}case_first` returns non-frozen string. *Jonathan Hefner* - Fix `#to_fs(:human_size)` to correctly work with negative numbers. *Earlopain* - Fix `BroadcastLogger#dup` so that it duplicates the logger's `broadcasts`. *Andrew Novoselac* - Fix issue where `bootstrap.rb` overwrites the `level` of a `BroadcastLogger`'s `broadcasts`. *Andrew Novoselac* - Fix `ActiveSupport::Cache` to handle outdated Marshal payload from Rails 6.1 format. Active Support's Cache is supposed to treat a Marshal payload that can no longer be deserialized as a cache miss. It fail to do so for compressed payload in the Rails 6.1 legacy format. *Jean Boussier* - Fix `OrderedOptions#dig` for array indexes. *fatkodima* - Fix time travel helpers to work when nested using with separate classes. *fatkodima* - Fix `delete_matched` for file cache store to work with keys longer than the max filename size. *fatkodima* and *Jonathan Hefner* - Fix compatibility with the `semantic_logger` gem. The `semantic_logger` gem doesn't behave exactly like stdlib logger in that `SemanticLogger#level` returns a Symbol while stdlib `Logger#level` returns an Integer. This caused the various `LogSubscriber` classes in Rails to break when assigned a `SemanticLogger` instance. *Jean Boussier*, *ojab* ##### Active Model - Make `==(other)` method of AttributeSet safe. *Dmitry Pogrebnoy* ##### Active Record - Fix renaming primary key index when renaming a table with a UUID primary key in PostgreSQL. *fatkodima* - Fix `where(field: values)` queries when `field` is a serialized attribute (for example, when `field` uses `ActiveRecord::Base.serialize` or is a JSON column). *João Alves* - Prevent marking broken connections as verified. *Daniel Colson* - Don't mark Float::INFINITY as changed when reassigning it When saving a record with a float infinite value, it shouldn't mark as changed *Maicol Bentancor* - `ActiveRecord::Base.table_name` now returns `nil` instead of raising "undefined method `abstract_class?` for Object:Class". *a5-stable* - Fix upserting for custom `:on_duplicate` and `:unique_by` consisting of all inserts keys. *fatkodima* - Fixed an [issue](https://togithub.com/rails/rails/issues/49809) where saving a record could innappropriately `dup` its attributes. *Jonathan Hefner* - Dump schema only for a specific db for rollback/up/down tasks for multiple dbs. *fatkodima* - Fix `NoMethodError` when casting a PostgreSQL `money` value that uses a comma as its radix point and has no leading currency symbol. For example, when casting `"3,50"`. *Andreas Reischuck* and *Jonathan Hefner* - Re-enable support for using `enum` with non-column-backed attributes. Non-column-backed attributes must be previously declared with an explicit type. For example: ```ruby class Post < ActiveRecord::Base attribute :topic, :string enum topic: %i[science tech engineering math] end ``` *Jonathan Hefner* - Raise on `foreign_key:` being passed as an array in associations *Nikita Vasilevsky* - Return back maximum allowed PostgreSQL table name to 63 characters. *fatkodima* - Fix detecting `IDENTITY` columns for PostgreSQL < 10. *fatkodima* ##### Action View - Fix the `number_to_human_size` view helper to correctly work with negative numbers. *Earlopain* - Automatically discard the implicit locals injected by collection rendering for template that can't accept them When rendering a collection, two implicit variables are injected, which breaks templates with strict locals. Now they are only passed if the template will actually accept them. *Yasha Krasnou*, *Jean Boussier* - Fix `@rails/ujs` calling `start()` an extra time when using bundlers *Hartley McGuire*, *Ryunosuke Sato* - Fix the `capture` view helper compatibility with HAML and Slim When a blank string was captured in HAML or Slim (and possibly other template engines) it would instead return the entire buffer. *Jean Boussier* ##### Action Pack - Fix a race condition that could cause a `Text file busy - chromedriver` error with parallel system tests *Matt Brictson* - Fix `StrongParameters#extract_value` to include blank values Otherwise composite parameters may not be parsed correctly when one of the component is blank. *fatkodima*, *Yasha Krasnou*, *Matthias Eiglsperger* - Add `racc` as a dependency since it will become a bundled gem in Ruby 3.4.0 *Hartley McGuire* - Support handling Enumerator for non-buffered responses. *Zachary Scott* ##### Active Job - No changes. ##### Action Mailer - No changes. ##### Action Cable - No changes. ##### Active Storage - No changes. ##### Action Mailbox - No changes. ##### Action Text - Compile ESM package that can be used directly in the browser as actiontext.esm.js *Matias Grunberg* - Fix using actiontext.js with Sprockets *Matias Grunberg* - Upgrade Trix to 2.0.7 *Hartley McGuire* - Fix using Trix with Sprockets *Hartley McGuire* ##### Railties - Fix running `db:system:change` when app has no Dockerfile. *Hartley McGuire* - If you accessed `config.eager_load_paths` and friends, later changes to `config.paths` were not reflected in the expected auto/eager load paths. Now, they are. This bug has been latent since Rails 3. Fixes [#49629](https://togithub.com/rails/rails/issues/49629). *Xavier Noria* ### [`v7.1.1`](https://togithub.com/rails/rails/releases/tag/v7.1.1): 7.1.1 [Compare Source](https://togithub.com/rails/rails/compare/v7.1.0...v7.1.1) #### Active Support - Add support for keyword arguments when delegating calls to custom loggers from `ActiveSupport::BroadcastLogger`. *Jenny Shen* - `NumberHelper`: handle objects responding `to_d`. *fatkodima* - Fix RedisCacheStore to properly set the TTL when incrementing or decrementing. This bug was only impacting Redis server older than 7.0. *Thomas Countz* - Fix MemoryStore to prevent race conditions when incrementing or decrementing. *Pierre Jambet* #### Active Model - No changes. #### Active Record - Fix auto populating IDENTITY columns for PostgreSQL. *fatkodima* - Fix "ArgumentError: wrong number of arguments (given 3, expected 2)" when down migrating `rename_table` in older migrations. *fatkodima* - Do not require the Action Text, Active Storage and Action Mailbox tables to be present when running when running test on CI. *Rafael Mendonça França* #### Action View - Updated `@rails/ujs` files to ignore certain data-\* attributes when element is contenteditable. This fix was already landed in >= 7.0.4.3, < 7.1.0. \[[CVE-2023-23913](https://togithub.com/advisories/GHSA-xp5h-f8jf-rc8q)] *Ryunosuke Sato* #### Action Pack - No changes. #### Active Job - Don't log enqueuing details when the job wasn't enqueued. *Dustin Brown* #### Action Mailer - No changes. #### Action Cable - No changes. #### Active Storage - No changes. #### Action Mailbox - No changes. #### Action Text - No changes. #### Railties - Ensures the Rails generated Dockerfile uses correct ruby version and matches Gemfile. *Abhay Nikam* ### [`v7.1.0`](https://togithub.com/rails/rails/releases/tag/v7.1.0): 7.1.0 [Compare Source](https://togithub.com/rails/rails/compare/v7.0.8...v7.1.0) #### Active Support - Fix `AS::MessagePack` with `ENV["RAILS_MAX_THREADS"]`. *Jonathan Hefner* - Add a new public API for broadcasting logs This feature existed for a while but was until now a private API. Broadcasting log allows to send log message to difference sinks (STDOUT, a file ...) and is used by default in the development environment to write logs both on STDOUT and in the "development.log" file. Basic usage: ```ruby stdout_logger = Logger.new(STDOUT) file_logger = Logger.new("development.log") broadcast = ActiveSupport::BroadcastLogger.new(stdout_logger, file_logger) broadcast.info("Hello!") # The "Hello!" message is written on STDOUT and in the log file. ``` Adding other sink(s) to the broadcast: ```ruby broadcast = ActiveSupport::BroadcastLogger.new broadcast.broadcast_to(Logger.new(STDERR)) ``` Remove a sink from the broadcast: ```ruby stdout_logger = Logger.new(STDOUT) broadcast = ActiveSupport::BroadcastLogger.new(stdout_logger) broadcast.stop_broadcasting_to(stdout_logger) ``` *Edouard Chin* - Fix Range#overlap? not taking empty ranges into account on Ruby < 3.3 *Nobuyoshi Nakada*, *Shouichi Kamiya*, *Hartley McGuire* - Use Ruby 3.3 Range#overlap? if available *Yasuo Honda* - Add `bigdecimal` as Active Support dependency that is a bundled gem candidate for Ruby 3.4. `bigdecimal` 3.1.4 or higher version will be installed. Ruby 2.7 and 3.0 users who want `bigdecimal` version 2.0.0 or 3.0.0 behavior as a default gem, pin the `bigdecimal` version in your application Gemfile. *Koichi ITO* - Add `drb`, `mutex_m` and `base64` that are bundled gem candidates for Ruby 3.4 *Yasuo Honda* - When using cache format version >= 7.1 or a custom serializer, expired and version-mismatched cache entries can now be detected without deserializing their values. *Jonathan Hefner* - Make all cache stores return a boolean for `#delete` Previously the `RedisCacheStore#delete` would return `1` if the entry exists and `0` otherwise. Now it returns true if the entry exists and false otherwise, just like the other stores. The `FileStore` would return `nil` if the entry doesn't exists and returns `false` now as well. *Petrik de Heus* - Active Support cache stores now support replacing the default compressor via a `:compressor` option. The specified compressor must respond to `deflate` and `inflate`. For example: ```ruby module MyCompressor def self.deflate(string) ``` ### compression logic... end def self.inflate(compressed) ### decompression logic... end end config.cache_store = :redis_cache_store, { compressor: MyCompressor } ``` *Jonathan Hefner* - Active Support cache stores now support a `:serializer` option. Similar to the `:coder` option, serializers must respond to `dump` and `load`. However, serializers are only responsible for serializing a cached value, whereas coders are responsible for serializing the entire `ActiveSupport::Cache::Entry` instance. Additionally, the output from serializers can be automatically compressed, whereas coders are responsible for their own compression. Specifying a serializer instead of a coder also enables performance optimizations, including the bare string optimization introduced by cache format version 7.1. The `:serializer` and `:coder` options are mutually exclusive. Specifying both will raise an `ArgumentError`. *Jonathan Hefner* - Fix `ActiveSupport::Inflector.humanize(nil)` raising ``NoMethodError: undefined method `end_with?' for nil:NilClass``. *James Robinson* - Don't show secrets for `ActiveSupport::KeyGenerator#inspect`. Before: ```ruby ActiveSupport::KeyGenerator.new(secret).inspect "#<%= html_escape_once("this & that & the other") %>
``` Before this change, that would be double-escaped and render as: ```htmlthis & that & the other
``` After this change, it renders correctly as: ```htmlthis & that & the other
``` Fixes [#48256](https://togithub.com/rails/rails/issues/48256) *Mike Dalessio* - Deprecate `SafeBuffer#clone_empty`. This method has not been used internally since Rails 4.2.0. *Mike Dalessio* - `MessageEncryptor`, `MessageVerifier`, and `config.active_support.message_serializer` now accept `:message_pack` and `:message_pack_allow_marshal` as serializers. These serializers require the [`msgpack` gem](https://rubygems.org/gems/msgpack) (>= 1.7.0). The Message Pack format can provide improved performance and smaller payload sizes. It also supports round-tripping some Ruby types that are not supported by JSON. For example: ```ruby verifier = ActiveSupport::MessageVerifier.new("secret") data = [{ a: 1 }, { b: 2 }.with_indifferent_access, 1.to_d, Time.at(0, 123)] message = verifier.generate(data) ``` ### BEFORE with config.active_support.message_serializer = :json verifier.verified(message) ### => \[{"a"=>1}, {"b"=>2}, "1.0", "1969-12-31T18:00:00.000-06:00"] verifier.verified(message).map(&:class) ### => \[Hash, Hash, String, String] ### AFTER with config.active_support.message_serializer = :message_pack verifier.verified(message) ### => \[{:a=>1}, {"b"=>2}, 0.1e1, 1969-12-31 18:00:00.000123 -0600] verifier.verified(message).map(&:class) ### => \[Hash, ActiveSupport::HashWithIndifferentAccess, BigDecimal, Time] ``` The `:message_pack` serializer can fall back to deserializing with `ActiveSupport::JSON` when necessary, and the `:message_pack_allow_marshal` serializer can fall back to deserializing with `Marshal` as well as `ActiveSupport::JSON`. Additionally, the `:marshal`, `:json`, and `:json_allow_marshal` serializers can now fall back to deserializing with `ActiveSupport::MessagePack` when necessary. These behaviors ensure old messages can still be read so that migration is easier. *Jonathan Hefner* - A new `7.1` cache format is available which includes an optimization for bare string values such as view fragments. The `7.1` cache format is used by default for new apps, and existing apps can enable the format by setting `config.load_defaults 7.1` or by setting `config.active_support.cache_format_version = 7.1` in `config/application.rb` or a `config/environments/*.rb` file. Cache entries written using the `6.1` or `7.0` cache formats can be read when using the `7.1` format. To perform a rolling deploy of a Rails 7.1 upgrade, wherein servers that have not yet been upgraded must be able to read caches from upgraded servers, leave the cache format unchanged on the first deploy, then enable the `7.1` cache format on a subsequent deploy. *Jonathan Hefner* - Active Support cache stores can now use a preconfigured serializer based on `ActiveSupport::MessagePack` via the `:serializer` option: ```ruby config.cache_store = :redis_cache_store, { serializer: :message_pack } ``` The `:message_pack` serializer can reduce cache entry sizes and improve performance, but requires the [`msgpack` gem](https://rubygems.org/gems/msgpack) (>= 1.7.0). The `:message_pack` serializer can read cache entries written by the default serializer, and the default serializer can now read entries written by the `:message_pack` serializer. These behaviors make it easy to migrate between serializer without invalidating the entire cache. *Jonathan Hefner* - `Object#deep_dup` no longer duplicate named classes and modules. Before: ```ruby hash = { class: Object, module: Kernel } hash.deep_dup # => {:class=>#Configuration
