actionview 7.1.0.rc1

on Ruby Gems

Active Support

• 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)

• 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

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

Active Record

• Better naming for unique constraints support.

  Naming unique keys leads to misunderstanding it's a short-hand of unique indexes.
  Just naming it unique constraints is not misleading.

  In Rails 7.1.0.beta1 or before:

  add_unique_key :sections, [:position], deferrable: :deferred, name: "unique_section_position"
  remove_unique_key :sections, name: "unique_section_position"

  Now:

  add_unique_constraint :sections, [:position], deferrable: :deferred, name: "unique_section_position"
  remove_unique_constraint :sections, name: "unique_section_position"

• Fix duplicate quoting for check constraint expressions in schema dump when using MySQL

  A check constraint with an expression, that already contains quotes, lead to an invalid schema
  dump with the mysql2 adapter.

  Fixes #42424.

  Felix Tscheulin

• Performance tune the SQLite3 adapter connection configuration

  For Rails applications, the Write-Ahead-Log in normal syncing mode with a capped journal size, a healthy shared memory buffer and a shared cache will perform, on average, 2× better.

• Allow SQLite3 busy_handler to be configured with simple max number of retries

  Retrying busy connections without delay is a preferred practice for performance-sensitive applications. Add support for a database.yml retries integer, which is used in a simple busy_handler function to retry busy connections without exponential backoff up to the max number of retries.

  Stephen Margheim

• The SQLite3 adapter now supports supports_insert_returning?

  Implementing the full supports_insert_returning? contract means the SQLite3 adapter supports auto-populated columns (#48241) as well as custom primary keys.

  Stephen Margheim

• Ensure the SQLite3 adapter handles default functions with the || concatenation operator

  Previously, this default function would produce the static string "'Ruby ' || 'on ' || 'Rails'".
  Now, the adapter will appropriately receive and use "Ruby on Rails".

  change_column_default "test_models", "ruby_on_rails", -> { "('Ruby ' || 'on ' || 'Rails')" }

  Stephen Margheim

• Dump PostgreSQL schemas as part of the schema dump.

  Lachlan Sylvester

Action View

• Introduce ActionView::TestCase.register_parser

  register_parser :rss, -> rendered { RSS::Parser.parse(rendered) }
  
  test "renders RSS" do
    article = Article.create!(title: "Hello, world")
  
    render formats: :rss, partial: article
  
    assert_equal "Hello, world", rendered.rss.items.last.title
  end

  By default, register parsers for :html and :json.

Action Pack

• Add support for #deep_merge and #deep_merge! to
  ActionController::Parameters.

  Sean Doyle

Active Job

• Set scheduled_at attribute as a Time object instead of epoch seconds, and serialize and deserialize the value
  when enqueued. Assigning a numeric/epoch value to scheduled_at= is deprecated; use a Time object instead.

  Deserializes enqueued_at as a Time instead of ISO8601 String.

  Ben Sheldon

• Clarify the backoff strategy for the recommended :wait option when retrying jobs

  wait: :exponentially_longer is waiting polynomially longer, so it is now recommended to use wait: :polynomially_longer to keep the same behavior.

  Victor Mours

Action Mailer

• Introduce ActionMailer::FormBuilder

  Use the default_form_builder method in mailers to set the default form builder
  for templates rendered by that mailer. Matches the behaviour in Action Controller.

  Alex Ghiculescu

Action Cable

• No changes.

Active Storage

• Add expires_at option to ActiveStorage::Blob#signed_id.

  rails_blob_path(user.avatar, disposition: "attachment", expires_at: 30.minutes.from_now)
  <%= image_tag rails_blob_path(user.avatar.variant(resize: "100x100"), expires_at: 30.minutes.from_now) %>

  Aki

• Allow attaching File and Pathname when assigning attributes, e.g.

  User.create!(avatar: File.open("image.jpg"))
  User.create!(avatar: file_fixture("image.jpg"))

  Dorian Marié

Action Mailbox

• No changes.

Action Text

• No changes.

Railties

• Require concurrent-ruby in config/puma.rb so that Puma can boot in
  production when WEB_CONCURRENCY is not explicitly specified.

  Fixes #49323.

  Matt Brictson

• Raise error when generating attribute with dangerous name.

  The following will now raise an error as save and hash are already
  defined by Active Record.

  $ bin/rails generate model Post save
  $ bin/rails generate model Post hash
