Always clear
CurrentAttributesinstances.Previously
CurrentAttributesinstance would be reset at the end of requests.Meaning its attributes would be re-initialized.
This is problematic because it assume these objects don't hold any state
other than their declared attribute, which isn't always the case, and
can lead to state leak across request.
Now
CurrentAttributesinstances are abandoned at the end of a request,and a new instance is created at the start of the next request.

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
parallelizemethod:or via the application configuration:

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 CASCADEforeign keys, ActiveRecord would silently delete alldata 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_integrityinside a transaction, butPRAGMA foreign_keyscannot 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_integritynow wraps the transaction insteadof 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

db_test, instead of the numbered parallel worker database,i.e.
db_test_{n}.Adam Maas

Fix time attribute dirty tracking with timezone conversions.
Time-only attributes now maintain a fixed date of 2000-01-01 during timezone conversions,

due to timezone conversion causing internal date shifts.

Add ability to change transaction isolation for all pools within a block.
This functionality is useful if your application needs to change the database
transaction isolation for a request or action.
Calling
ActiveRecord.with_transaction_isolation_level(level) {}in an around filter ormiddleware will set the transaction isolation for all pools accessed within the block,
but not for the pools that aren't.
This works with explicit and implicit transactions:

an error has been deprecated with the aim of removing the configuration option in Rails 8.2.

Mike Dalessio
Allow signed ID verifiers to be configurable via
Rails.application.message_verifiersPrior to this change, the primary way to configure signed ID verifiers was
to set
signed_id_verifieron each model class:And if the developer did not set
signed_id_verifier, a verifier would beinstantiated with a secret derived from
secret_key_baseand the followingoptions:
Thus it was cumbersome to rotate configuration for all verifiers.
This change defines a new Rails config: [
config.active_record.use_legacy_signed_id_verifier][].The default value is
:generate_and_verify, which preserves the previousbehavior. However, when set to
:verify, signed ID verifiers will useconfiguration from
Rails.application.message_verifiers(specifically,Rails.application.message_verifiers["active_record/signed_id"]) togenerate and verify signed IDs, but will also verify signed IDs using the
older configuration.
To avoid complication, the new behavior only applies when
signed_id_verifier_secretis not set on a model class or any of its ancestors. Additionally,
signed_id_verifier_secretis now deprecated. If you are currently settingsigned_id_verifier_secreton a model class, you can setsigned_id_verifierinstead:

Allow bypassing primary key/constraint addition in

Support disabling indexes for MySQL v8.0.0+ and MariaDB v10.6.0+
MySQL 8.0.0 added an option to disable indexes from being used by the query
optimizer by making them "invisible". This allows the index to still be maintained
and updated but no queries will be permitted to use it. This can be useful for adding
new invisible indexes or making existing indexes invisible before dropping them
to ensure queries are not negatively affected.
See https://dev.mysql.com/blog-archive/mysql-8-0-invisible-indexes/ for more details.
MariaDB 10.6.0 also added support for this feature by allowing indexes to be "ignored"
in queries. See https://mariadb.com/kb/en/ignored-indexes/ for more details.
Active Record now supports this option for MySQL 8.0.0+ and MariaDB 10.6.0+ for
index creation and alteration where the new index option
enabled: true/falsecan bepassed to column and index methods as below:

Introduce versions formatter for the schema dumper.
It is now possible to override how schema dumper formats versions information inside the
structure.sqlfile. Currently, the versions are simply sorted in the decreasing order.Within large teams, this can potentially cause many merge conflicts near the top of the list.
Now, the custom formatter can be provided with a custom sorting logic (e.g. by hash values
of the versions), which can greatly reduce the number of conflicts.
fatkodima
Serialized attributes can now be marked as comparable.
A not rare issue when working with serialized attributes is that the serialized representation of an object
can change over time. Either because you are migrating from one serializer to the other (e.g. YAML to JSON or to msgpack),
or because the serializer used subtly changed its output.
One example is libyaml that used to have some extra trailing whitespaces, and recently fixed that.
When this sorts of thing happen, you end up with lots of records that report being changed even though
they aren't, which in the best case leads to a lot more writes to the database and in the worst case lead to nasty bugs.
The solution is to instead compare the deserialized representation of the object, however Active Record
can't assume the deserialized object has a working
==method. Hence why this new functionality is opt-in.Jean Boussier

Argument errors related to strict locals in templates now raise an
ActionView::StrictLocalsError, and all other argument errors are reraised as-is.Previously, any
ArgumentErrorraised during template rendering was swallowed during strictlocal error handling, so that an
ArgumentErrorunrelated to strict locals (e.g., a helpermethod invoked with incorrect arguments) would be replaced by a similar
ArgumentErrorwith anunrelated backtrace, making it difficult to debug templates.
Now, any
ArgumentErrorunrelated to strict locals is reraised, preserving the originalbacktrace for developers.
Also note that
ActionView::StrictLocalsErroris a subclass ofArgumentError, so any existingcode that rescues
ArgumentErrorwill continue to work.Fixes #52227.

Optimize
ActionDispatch::Http::URL.build_host_urlwhen protocol is included in host.When using URL helpers with a host that includes the protocol (e.g.,
{ host: "https://example.com" }),skip unnecessary protocol normalization and string duplication since the extracted protocol is already
in the correct format. This eliminates 2 string allocations per URL generation and provides a ~10%
performance improvement for this case.

Add support for
rack.response_finishedcallbacks in ActionDispatch::Executor.The executor middleware now supports deferring completion callbacks to later

rack.response_finishedcallbacksthat may rely on state that would be cleaned up by the executor's completion callbacks.
