Active Support

• Fix inflections to better handle overlapping acronyms.

  ```ruby ActiveSupport::Inflector.inflections(:en) do |inflect| inflect.acronym "USD" inflect.acronym "USDC" end

  "USDC".underscore # => "usdc" ```

  Said Kaldybaev

• Silence Dalli 4.0+ warning when using ActiveSupport::Cache::MemCacheStore.

  zzak

• Make delegate and delegate_missing_to work in BasicObject subclasses.

  Rafael Mendonça França

• Fix ActiveSupport::Inflector.humanize with international characters.

  ruby ActiveSupport::Inflector.humanize("áÉÍÓÚ") # => "Áéíóú" ActiveSupport::Inflector.humanize("аБВГДЕ") # => "Абвгде"

Active Model

• No changes.

Active Record

• Fix insert_all and upsert_all log message when called on anonymous classes.

  Gabriel Sobrinho

• Respect ActiveRecord::SchemaDumper.ignore_tables when dumping SQLite virtual tables.

  Hans Schnedlitz

• Restore previous instrumenter after execute_or_skip

  FutureResult#execute_or_skip replaces the thread's instrumenter with an EventBuffer to collect events published during async query execution. If the global async executor is saturated and the caller_runs fallback executes the task on the calling thread, we need to make sure the previous instrumenter is restored or the stale EventBuffer would stay in place and permanently swallow all subsequent sql.active_record notifications on that thread.

  Rosa Gutierrez

• Fix Ruby 4.0 delegator warning when calling inspect on ActiveRecord::Type::Serialized.

  Hammad Khan

• Fix support for table names containing hyphens.

  Evgeniy Demin

• Fix column deduplication for SQLite3 and PostgreSQL virtual (generated) columns.

  Column#== and Column#hash now account for virtual? so that the Deduplicable registry does not treat a generated column and a regular column with the same name and type as identical. Previously, if a generated column was registered first, a regular column on a different table could be deduplicated to the generated instance, silently excluding it from INSERT/UPDATE statements.

  Jay Huber

• Fix merging relations with arel equality predicates with null relations.

  fatkodima

• Fix SQLite3 schema dump for non-autoincrement integer primary keys.

  Previously, schema.rb should incorrectly restore that table with an auto incrementing primary key.

  Chris Hasiński

• Fix PostgreSQL schema_search_path not being reapplied after reset! or reconnect!.

  The schema_search_path configured in database.yml is now correctly reapplied instead of falling back to PostgreSQL defaults.

  Tobias Egli

• Ensure batched preloaded associations accounts for klass when grouping to avoid issues with STI.

  zzak, Stjepan Hadjic

• Fix ActiveRecord::SoleRecordExceeded#record to return the relation.

  This was the case until Rails 7.2, but starting from 8.0 it started mistakenly returning the model class.

  Jean Boussier

• Improve PostgreSQLAdapter resilience to Timeout.timeout.

  Better handle asynchronous exceptions being thrown inside the reconnect! method.

  This may fixes some deep errors such as:

  undefined method `key?' for nil:NilClass (NoMethodError) if !type_map.key?(oid)

  Jean Boussier

• Fix eager_load when loading has_many assocations with composite primary keys.

  This would result in some records being loaded multiple times.

  Martin-Alexander

Action View

• Fix encoding errors for string locals containing non-ASCII characters.

  Kataoka Katsuki

• Fix collection caching to only forward expires_in argument if explicitly set.

  Pieter Visser

• Fix file_field to join mime types with a comma when provided as Array

  ruby file_field(:article, :image, accept: ['image/png', 'image/gif', 'image/jpeg'])

  Now behaves likes:

  file_field(:article, :image, accept: 'image/png,image/gif,image/jpeg')

  Bogdan Gusiev

• Fix strict locals parsing to handle multiline definitions.

  Said Kaldybaev

Action Pack

• Add config.action_controller.live_streaming_excluded_keys to control execution state sharing in ActionController::Live.

  When using ActionController::Live, actions are executed in a separate thread that shares state from the parent thread. This new configuration allows applications to opt-out specific state keys that should not be shared.

  This is useful when streaming inside a connected_to block, where you may want the streaming thread to use its own database connection context.

  ```ruby

  config/application.rb

  config.action_controller.live_streaming_excluded_keys = [:active_record_connected_to_stack] ```

  By default, all keys are shared.
