    Jean Boussier

  • Work around a Ruby bug that can cause a VM crash.

    This would happen if using TaggerLogger with a Proc formatter on which you called object_id.

    [BUG] Object ID seen, but not in mapping table: proc

    Jean Boussier

  • Fix ActiveSupport::Notifications.publish_event to preserve units.

    This solves the incorrect reporting of time spent running Active Record asynchronous queries (by a factor 1000).

    Jean Boussier

  • Revert "Fix ActiveSupport::JSON.encode to prevent duplicate keys." introduced in 7.1.3

    If the same key exist in both String and Symbol form, json encoder again emits the same key twice. Reaseon

    ActiveSupport 7.1.3

    {a: 1, "a" => 2}.to_json
# gives: "{\"a\":2}"

    ActiveSupport 7.1.4

    {a: 1, "a" => 2}.to_json

    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

Rails 7.1.2 (November 10, 2023)

  • 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  • Fix ActiveSupport::Cache to handle outdated Marshal payload from Rails 6.1 format.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

Rails 7.1.1 (October 11, 2023)

  • Add support for keyword arguments when delegating calls to custom loggers from ActiveSupport::BroadcastLogger.

    Edouard Chin

  • 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

Rails 7.1.0 (October 05, 2023)

  • No changes.

Rails 7.1.0.rc2 (October 01, 2023)

  • Fix AS::MessagePack with ENV["RAILS_MAX_THREADS"].

    Jonathan Hefner

Rails 7.1.0.rc1 (September 27, 2023)

  • 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:

    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:

    broadcast = ActiveSupport::BroadcastLogger.new
broadcast.broadcast_to(Logger.new(STDERR))

    Remove a sink from the broadcast:

    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

Rails 7.1.0.beta1 (September 13, 2023)

  • 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:

    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:

    ActiveSupport::KeyGenerator.new(secret).inspect
"#<ActiveSupport::KeyGenerator:0x0000000104888038 ... @secret=\"\\xAF\\bFh]LV}q\\nl\\xB2U\\xB3 ... >"

    After:

    ActiveSupport::KeyGenerator::Aes256Gcm(secret).inspect
"#<ActiveSupport::KeyGenerator:0x0000000104888038>"

    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:

    ActiveSupport::MessageEncryptor.new(secret, cipher: "aes-256-gcm").inspect
"#<ActiveSupport::MessageEncryptor:0x0000000104888038 ... @secret=\"\\xAF\\bFh]LV}q\\nl\\xB2U\\xB3 ... >"

    After:

    ActiveSupport::MessageEncryptor.new(secret, cipher: "aes-256-gcm").inspect
"#<ActiveSupport::MessageEncryptor:0x0000000104888038>"

    Petrik de Heus

  • Don't show contents for EncryptedConfiguration#inspect.

    Before:

    Rails.application.credentials.inspect
"#<ActiveSupport::EncryptedConfiguration:0x000000010d2b38e8 ... @config={:secret=>\"something secret\"} ... @key_file_contents=\"915e4ea054e011022398dc242\" ...>"

    After:

    Rails.application.credentials.inspect
"#<ActiveSupport::EncryptedConfiguration:0x000000010d2b38e8>"

    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:

    <p><%= html_escape_once("this & that &amp; the other") %></p>

    Before this change, that would be double-escaped and render as:

    <p>this &amp;amp; that &amp;amp; the other</p>

    After this change, it renders correctly as:

    <p>this &amp; that &amp; the other</p>

    Fixes #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 (>= 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:

    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:

    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 (>= 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:

    hash = { class: Object, module: Kernel }
hash.deep_dup # => {:class=>#<Class:0x00000001063ffc80>, :module=>#<Module:0x00000001063ffa00>}

    After:

    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.

    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.

    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

    client.timeout # => 5
client.with(timeout: 1) do
  client.timeout # => 1
end
client.timeout # => 5

    Jean Boussier

  • Remove deprecated support to generate incorrect RFC 4122 UUIDs when providing a namespace ID that is not one of the constants defined on Digest::UUID.

    Rafael Mendonça França

  • Deprecate config.active_support.use_rfc4122_namespaced_uuids.

    Rafael Mendonça França

  • Remove implicit conversion of objects into String by ActiveSupport::SafeBuffer.

    Rafael Mendonça França

  • Remove deprecated active_support/core_ext/range/include_time_with_zone file.

    Rafael Mendonça França

  • Deprecate config.active_support.remove_deprecated_time_with_zone_name.

    Rafael Mendonça França

  • Remove deprecated override of ActiveSupport::TimeWithZone.name.

    Rafael Mendonça França

  • Deprecate config.active_support.disable_to_s_conversion.

    Rafael Mendonça França

  • 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

    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:

    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:

    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.

    string = "<div>test</div>".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.

    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.

    # 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

    error = assert_raises(ArgumentError) do
  perform_service(param: 'exception')
end
assert_match(/incorrect param/i, error.message)

    you can now write this

    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:

    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:

    # 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:

    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)

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:

    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)

  • 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.

    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

    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?

  • 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

    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

    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.

  • 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.

    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.

    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.

    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:

    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:

    config.cache_store = :redis_cache_store, pool: true

    Or pass individual options via :pool option:

    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, but Class#subclasses was kept, breaking the feature detection.
