• Add public API for before_fork_hook in parallel testing.

  Introduces a public API for calling the before fork hooks implemented by parallel testing.

  parallelize_before_fork do
      # perform an action before test processes are forked
  end

• Implement ability to skip creating parallel testing databases.

  With parallel testing, Rails will create a database per process. If this isn't desirable or you would like to implement databases handling on your own, you can now turn off this default behavior.

  To skip creating a database per process, you can change it via the parallelize method:

  parallelize(workers: 10, parallelize_databases: false)

  or via the application configuration:

  config.active_support.parallelize_databases = false

• Allow to configure maximum cache key sizes

  When the key exceeds the configured limit (250 bytes by default), it will be truncated and the digest of the rest of the key appended to it.

  Note that previously ::ActiveSupport::Cache::RedisCacheStore allowed up to 1kb cache keys before truncation, which is now reduced to 250 bytes.

  config.cache_store = :redis_cache_store, { max_key_size: 64 }

• Use UNLINK command instead of DEL in ::ActiveSupport::Cache::RedisCacheStore for non-blocking deletion.

  Aron Roh

• Add Cache#read_counter and Cache#write_counter

  Rails.cache.write_counter("foo", 1)
  Rails.cache.read_counter("foo") # => 1
  Rails.cache.increment("foo")
  Rails.cache.read_counter("foo") # => 2

• Introduce ActiveSupport::Testing::ErrorReporterAssertions#capture_error_reports

  Captures all reported errors from within the block that match the given error class.

  reports = capture_error_reports(IOError) do
    Rails.error.report(IOError.new("Oops"))
    Rails.error.report(IOError.new("Oh no"))
    Rails.error.report(StandardError.new)
  end
  
  assert_equal 2, reports.size
  assert_equal "Oops", reports.first.error.message
  assert_equal "Oh no", reports.last.error.message

  Andrew Novoselac

• Introduce ActiveSupport::ErrorReporter#add_middleware

  When reporting an error, the error context middleware will be called with the reported error and base execution context. The stack may mutate the context hash. The mutated context will then be passed to error subscribers. Middleware receives the same parameters as ErrorReporter#report.

  Andrew Novoselac, Sam Schmidt

• Change execution wrapping to report all exceptions, including Exception.

  If a more serious error like SystemStackError or NoMemoryError happens, the error reporter should be able to report these kinds of exceptions.

  Gannon McGibbon

• ActiveSupport::Testing::Parallelization.before_fork_hook allows declaration of callbacks that are invoked immediately before forking test workers.

  Mike Dalessio

• Allow the #freeze_time testing helper to accept a date or time argument.

  Time.current # => Sun, 09 Jul 2024 15:34:49 EST -05:00
  freeze_time Time.current + 1.day
  sleep 1
  Time.current # => Mon, 10 Jul 2024 15:34:49 EST -05:00

• ::ActiveSupport::JSON now accepts options

  It is now possible to pass options to ::ActiveSupport::JSON:

  ActiveSupport::JSON.decode('{"key": "value"}', symbolize_names: true) # => { key: "value" }

• ::ActiveSupport::Testing::NotificationAssertions's assert_notification now matches against payload subsets by default.

  Previously the following assertion would fail due to excess key vals in the notification payload. Now with payload subset matching, it will pass.

  assert_notification("post.submitted", title: "Cool Post") do
    ActiveSupport::Notifications.instrument("post.submitted", title: "Cool Post", body: "Cool Body")
  end

  Additionally, you can now persist a matched notification for more customized assertions.

  notification = assert_notification("post.submitted", title: "Cool Post") do
    ActiveSupport::Notifications.instrument("post.submitted", title: "Cool Post", body: Body.new("Cool Body"))
  end
  
  assert_instance_of(Body, notification.payload[:body])

• Deprecate String#mb_chars and ::ActiveSupport::Multibyte::Chars.

  These APIs are a relic of the Ruby 1.8 days when Ruby strings weren't encoding aware. There is no legitimate reasons to need these APIs today.

  Jean Boussier

• Deprecate ::ActiveSupport::Configurable

  Sean Doyle

• nil.to_query("key") now returns key.

  Previously it would return key=, preventing round tripping with Rack::Utils.parse_nested_query.

  Erol Fornoles

• Avoid wrapping redis in a ConnectionPool when using ::ActiveSupport::Cache::RedisCacheStore if the :redis option is already a ConnectionPool.

  Joshua Young

• Alter ERB::Util.tokenize to return :PLAIN token with full input string when string doesn't contain ERB tags.

  Martin Emde

• Fix a bug in ERB::Util.tokenize that causes incorrect tokenization when ERB tags are preceded by multibyte characters.

  Martin Emde

• Add ::ActiveSupport::Testing::NotificationAssertions module to help with testing ::ActiveSupport::Notifications.

  Nicholas La Roux, Yishu See, Sean Doyle

• ActiveSupport::CurrentAttributes#attributes now will return a new hash object on each call.

  Previously, the same hash object was returned each time that method was called.

  fatkodima

• ActiveSupport::JSON.encode supports CIDR notation.

  Previously:

  ActiveSupport::JSON.encode(IPAddr.new("172.16.0.0/24")) # => "\"172.16.0.0\""

  After this change:

  ActiveSupport::JSON.encode(IPAddr.new("172.16.0.0/24")) # => "\"172.16.0.0/24\""

• Make ::ActiveSupport::FileUpdateChecker faster when checking many file-extensions.
