Bump activerecord from 8.0.3 to 8.1.0

[dependabot]

Bumps activerecord from 8.0.3 to 8.1.0.

Release notes

Sourced from activerecord's releases.

8.1.0

Active Support

• Remove deprecated passing a Time object to Time#since.

  Rafael Mendonça França

• Remove deprecated Benchmark.ms method. It is now defined in the benchmark gem.

  Rafael Mendonça França

• Remove deprecated addition for Time instances with ActiveSupport::TimeWithZone.

  Rafael Mendonça França

• Remove deprecated support for to_time to preserve the system local time. It will now always preserve the receiver timezone.

  Rafael Mendonça França

• Deprecate config.active_support.to_time_preserves_timezone.

  Rafael Mendonça França

• Standardize event name formatting in assert_event_reported error messages.

  The event name in failure messages now uses .inspect (e.g., name: "user.created") to match assert_events_reported and provide type clarity between strings and symbols. This only affects tests that assert on the failure message format itself.

  George Ma

• Fix Enumerable#sole to return the full tuple instead of just the first element of the tuple.

  Olivier Bellone

• Fix parallel tests hanging when worker processes die abruptly.

  Previously, if a worker process was killed (e.g., OOM killed, kill -9) during parallel test execution, the test suite would hang forever waiting for the dead worker.

  Joshua Young

• Add config.active_support.escape_js_separators_in_json.

  Introduce a new framework default to skip escaping LINE SEPARATOR (U+2028) and PARAGRAPH SEPARATOR (U+2029) in JSON.

  Historically these characters were not valid inside JavaScript literal strings but that changed in ECMAScript 2019. As such it's no longer a concern in modern browsers: https://caniuse.com/mdn-javascript_builtins_json_json_superset.

Changelog

Sourced from activerecord's changelog.

Rails 8.1.0 (October 22, 2025)

• Fix SQLite3 data loss during table alterations with CASCADE foreign keys.

  When altering a table in SQLite3 that is referenced by child tables with ON DELETE CASCADE foreign keys, ActiveRecord would silently delete all data from the child tables. This occurred because SQLite requires table recreation for schema changes, and during this process the original table is temporarily dropped, triggering CASCADE deletes on child tables.

  The root cause was incorrect ordering of operations. The original code wrapped disable_referential_integrity inside a transaction, but PRAGMA foreign_keys cannot be modified inside a transaction in SQLite - attempting to do so simply has no effect. This meant foreign keys remained enabled during table recreation, causing CASCADE deletes to fire.

  The fix reverses the order to follow the official SQLite 12-step ALTER TABLE procedure: disable_referential_integrity now wraps the transaction instead of being wrapped by it. This ensures foreign keys are properly disabled before the transaction starts and re-enabled after it commits, preventing CASCADE deletes while maintaining data integrity through atomic transactions.

  Ruy Rocha

• Add replicas to test database parallelization setup.

  Setup and configuration of databases for parallel testing now includes replicas.

  This fixes an issue when using a replica database, database selector middleware, and non-transactional tests, where integration tests running in parallel would select the base test database, i.e. db_test, instead of the numbered parallel worker database, i.e. db_test_{n}.

  Adam Maas

• Support virtual (not persisted) generated columns on PostgreSQL 18+

  PostgreSQL 18 introduces virtual (not persisted) generated columns, which are now the default unless the stored: true option is explicitly specified on PostgreSQL 18+.

  create_table :users do |t|
    t.string :name
    t.virtual :lower_name,  type: :string,  as: "LOWER(name)", stored: false
    t.virtual :name_length, type: :integer, as: "LENGTH(name)"
  end
