8.0.2

Active Support

• Fix setting to_time_preserves_timezone from new_framework_defaults_8_0.rb.

  fatkodima

• Fix Active Support Cache fetch_multi when local store is active.

  fetch_multi now properly yield to the provided block for missing entries
  that have been recorded as such in the local store.

  Jean Boussier

• Fix 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

• Fix RedisCacheStore and MemCacheStore to also handle connection pool related errors.

  These errors are rescued and reported to Rails.error.

  Jean Boussier

• Fix ActiveSupport::Cache#read_multi to respect version expiry when using local cache.

  zzak

• Fix ActiveSupport::MessageVerifier and ActiveSupport::MessageEncryptor configuration of on_rotation callback.

  verifier.rotate(old_secret).on_rotation { ... }

  Now both work as documented.

  Jean Boussier

• Fix ActiveSupport::MessageVerifier to always be able to verify both URL-safe and URL-unsafe payloads.

  This is to allow transitioning seemlessly from either configuration without immediately invalidating
  all previously generated signed messages.

  Jean Boussier, Florent Beaurain, Ali Sepehri

• Fix cache.fetch to honor the provided expiry when :race_condition_ttl is used.

  cache.fetch("key", expires_in: 1.hour, race_condition_ttl: 5.second) do
    "something"
  end

  In the above example, the final cache entry would have a 10 seconds TTL instead
  of the requested 1 hour.

  Dhia

• Better handle procs with splat arguments in set_callback.

  Radamés Roriz

• Fix String#mb_chars to not mutate the receiver.

  Previously it would call force_encoding on the receiver,
  now it dups the receiver first.

  Jean Boussier

• Improve ErrorSubscriber to also mark error causes as reported.

  This avoid some cases of errors being reported twice, notably in views because of how
  errors are wrapped in ActionView::Template::Error.

  Jean Boussier

• Fix Module#module_parent_name to return the correct name after the module has been named.

  When called on an anonymous module, the return value wouldn't change after the module was given a name
  later by being assigned to a constant.

  mod = Module.new
  mod.module_parent_name # => "Object"
  MyModule::Something = mod
  mod.module_parent_name # => "MyModule"

  Edouard Chin

• Fix inverting drop_table without options.

  fatkodima

• Fix count with group by qualified name on loaded relation.

  Ryuta Kamizono

• Fix sum with qualified name on loaded relation.

  Chris Gunther

• The SQLite3 adapter quotes non-finite Numeric values like "Infinity" and "NaN".

  Mike Dalessio

• Handle libpq returning a database version of 0 on no/bad connection in PostgreSQLAdapter.

  Before, this version would be cached and an error would be raised during connection configuration when
  comparing it with the minimum required version for the adapter. This meant that the connection could
  never be successfully configured on subsequent reconnection attempts.

  Now, this is treated as a connection failure consistent with libpq, raising a ActiveRecord::ConnectionFailed
  and ensuring the version isn't cached, which allows the version to be retrieved on the next connection attempt.

  Joshua Young, Rian McGuire

• Fix error handling during connection configuration.

  Active Record wasn't properly handling errors during the connection configuration phase.
  This could lead to a partially configured connection being used, resulting in various exceptions,
  the most common being with the PostgreSQLAdapter raising undefined method key?' for nilorTypeError: wrong argument type nil (expected PG::TypeMap)`.

  Jean Boussier

• Fix a case where a non-retryable query could be marked retryable.

  Hartley McGuire

• Handle circular references when autosaving associations.

  zzak

• PoolConfig no longer keeps a reference to the connection class.

  Keeping a reference to the class caused subtle issues when combined with reloading in
  development. Fixes #54343.

  Mike Dalessio

• Fix SQL notifications sometimes not sent when using async queries.

  Post.async_count
  ActiveSupport::Notifications.subscribed(->(*) { "Will never reach here" }) do
    Post.count
  end

  In rare circumstances and under the right race condition, Active Support notifications
  would no longer be dispatched after using an asynchronous query.
  This is now fixed.

  Edouard Chin

• Fix support for PostgreSQL enum types with commas in their name.

  Arthur Hess

• Fix inserts on MySQL with no RETURNING support for a table with multiple auto populated columns.

  Nikita Vasilevsky

• Fix joining on a scoped association with string joins and bind parameters.

  class Instructor < ActiveRecord::Base
    has_many :instructor_roles, -> { active }
  end
  
  class InstructorRole < ActiveRecord::Base
    scope :active, -> {
      joins("JOIN students ON instructor_roles.student_id = students.id")
      .where(students { status: 1 })
    }
  end
  
  Instructor.joins(:instructor_roles).first

  The above example would result in ActiveRecord::StatementInvalid because the
  active scope bind parameters would be lost.

  Jean Boussier

• Fix a potential race condition with system tests and transactional fixtures.

  Sjoerd Lagarde

• Fix autosave associations to no longer validated unmodified associated records.

  Active Record was incorrectly performing validation on associated record that
  weren't created nor modified as part of the transaction:

  Post.create!(author: User.find(1)) # Fail if user is invalid

  Jean Boussier

• Remember when a database connection has recently been verified (for
  two seconds, by default), to avoid repeated reverifications during a
  single request.

  This should recreate a similar rate of verification as in Rails 7.1,
  where connections are leased for the duration of a request, and thus
  only verified once.

  Matthew Draper

Action View

• Respect html_options[:form] when collection_checkboxes generates the
  hidden <input>.

  Riccardo Odone

• Layouts have access to local variables passed to render.

  This fixes #31680 which was a regression in Rails 5.1.

  Mike Dalessio

• Argument errors related to strict locals in templates now raise an
  ActionView::StrictLocalsError, and all other argument errors are reraised as-is.

  Previously, any ArgumentError raised during template rendering was swallowed during strict
  local error handling, so that an ArgumentError unrelated to strict locals (e.g., a helper
  method invoked with incorrect arguments) would be replaced by a similar ArgumentError with an
  unrelated backtrace, making it difficult to debug templates.

  Now, any ArgumentError unrelated to strict locals is reraised, preserving the original
  backtrace for developers.

  Also note that ActionView::StrictLocalsError is a subclass of ArgumentError, so any existing
  code that rescues ArgumentError will continue to work.

  Fixes #52227.

  Mike Dalessio

• Fix stack overflow error in dependency tracker when dealing with circular dependencies

  Jean Boussier

Action Pack

• Improve with_routing test helper to not rebuild the middleware stack.

  Otherwise some middleware configuration could be lost.

  Édouard Chin

• Add resource name to the ArgumentError that's raised when invalid :only or :except options are given to #resource or #resources

  This makes it easier to locate the source of the problem, especially for routes drawn by gems.

  Before:

  :only and :except must include only [:index, :create, :new, :show, :update, :destroy, :edit], but also included [:foo, :bar]
  

  After:

  Route `resources :products` - :only and :except must include only [:index, :create, :new, :show, :update, :destroy, :edit], but also included [:foo, :bar]
  

  Jeremy Green

• Fix url_for to handle :path_params gracefully when it's not a Hash.

• A Blob will no longer autosave associated Attachment.

  This fixes an issue where a record with an attachment would have
  its dirty attributes reset, preventing your after commit callbacks
  on that record to behave as expected.

  Note that this change doesn't require any changes on your application
  and is supposed to be internal. Active Storage Attachment will continue
  to be autosaved (through a different relation).

  After this change:

  { 1 => 2 }.with_indifferent_access.stringify_keys["1"] # => 2

  This change can be seen as a bug fix, but since it behaved like this for a very long time, we're deciding
  to not backport the fix and to make the change in a major release.

  Jean Boussier

  end
  
  class Right < ActiveRecord::Base

• Properly handle lazily pinned connection pools.

  Fixes #53147.

  When using transactional fixtures with system tests to similar tools

  "Cannot expire connection, it is owned by a different thread" errors.

  Jean Boussier

  The above now works as expected.

• Ensure ActiveRecord::Encryption.config is always ready before access.

  Previously, ActiveRecord::Encryption configuration was deferred until ActiveRecord::Base
  was loaded. Therefore, accessing ActiveRecord::Encryption.config properties before
  ActiveRecord::Base was loaded would give incorrect results.

  ActiveRecord::Encryption now has its own loading hook so that its configuration is set as
  soon as needed.

  When ActiveRecord::Base is loaded, even lazily, it in turn triggers the loading of
  ActiveRecord::Encryption, thus preserving the original behavior of having its config ready
  before any use of ActiveRecord::Base.

  Previously, using .left_outer_joins with the same child association would only join one of the parents.

  Now it will correctly join both parents.

  Fixes #41498.

• Ensure ActiveRecord::Encryption.config is always ready before access.

  Previously, ActiveRecord::Encryption configuration was deferred until ActiveRecord::Base
  was loaded. Therefore, accessing ActiveRecord::Encryption.config properties before
  ActiveRecord::Base was loaded would give incorrect results.

  ActiveRecord::Encryption now has its own loading hook so that its configuration is set as
  soon as needed.

  When ActiveRecord::Base is loaded, even lazily, it in turn triggers the loading of
  ActiveRecord::Encryption, thus preserving the original behavior of having its config ready
  before any use of ActiveRecord::Base.

• The db:prepare task no longer loads seeds when a non-primary database is created.

  Previously, the db:prepare task would load seeds whenever a new database
  is created, leading to potential loss of data if a database is added to an
  existing environment.

  Introduces a new database config property seeds to control whether seeds
  are loaded during db:prepare which defaults to true for primary database
  configs and false otherwise.

  Fixes #53348.
