Hi, Wojtek here. Let’s see a huge list of this week’s changes in the Rails codebase.
Action Cable server adapterization
Extract low-level Action Cable server responsibilities into ActionCable::Server abstractions.
This refactoring separates socket handling, concurrency primitives, and other transport-specific behavior from application-level connections and channels. It makes Action Cable more flexible as a framework and opens the door to alternative server implementations without changing user-facing channel and connection code.
Active Storage Guide update
Can be read on Edge Guides already.
Add shims for Ractor shareability methods
Adds new core extension to Kernel ractor_shareable?, ractor_make_shareable, ractor_shareable_proc, and ractor_shareable_lamda. In environments where those are available, it forwards them to the Ractor method, otherwise they are a no-op.
Make exception wrapper Ractor safe
Adds a configuration for ActionDispatch::ExceptionWrapper silent_exceptions and wrapper_exceptions to silence noisy framework exceptions and be able to decide which exceptions should unwrap to the original cause when reporting.
Support for default order
Adds default_order query method and association option which can be used to order records when no other order is specified.
This extends the functionality offered by implicit_order_column to scopes and associations.
Reject malformed Action Mailbox original recipients
Return 422 Unprocessable Content for malformed Mailgun, Postmark, and SendGrid raw email parameters.
Follow up improvements to Action Mailbox added in pull requests #57495, #57494, #57463, #57452, #57335.
Refactor ActiveJob::TestHelper to no longer walk descendants
Store the overrides in a couple data structures that can be easily cleared in constant time during teardown.
Pass a job to stopping? for fine-grained control over interruption
Allow queue adapters to inspect a job when deciding whether to interrupt at a checkpoint, and to optionally return a specific interruption reason.
Fix number_to_delimited mangling non-finite floats
Returns the underlying string representation Infinity, -Infinity, NaN for non-finite floats.
Another change fixes the number_to_rounded in similar manner.
Fix HTML-aware ERB compiler errors in bundled templates so they pass strict validations
Verified by running Herb gem.
Improve insert_all error message to show key mismatch
Includes the mismatched keys in the error raised by insert_all / upsert_all when the inserted objects have inconsistent attributes.
Book.insert_all [{ name: "Rework", author_id: 1 }, { name: "Remote", author_id: 1, isbn: "x" }]
# ArgumentError: All objects being inserted must have the same keys (extra: [:isbn])
Include valid values in Active Record Enum invalid-value error
Includes the list of valid values in the error raised when assigning an invalid value to an enum attribute.
Book.new(status: "bogus")
# ArgumentError: 'bogus' is not a valid status. Valid values are: "proposed", "written", "published"
Add missing docs for Rails.autoloaders
The interface available from Rails.autoloaders was documented in the autoloading guide. This patch adds missing documentation for the API docs.
Validate subcommand in rails plugin command
Command rails plugin foo bar silently ignored the invalid subcommand “foo” and proceeded to create a plugin named “bar”. Now it prints an error and exits with status 1.
Fix Active Record Pool Reaper thread leak
After parallelized test runs, the parent process leaked the Active Record Pool Reaper thread, holding open connection pools and file descriptors for up to reaping_frequency seconds (or indefinitely if never reaped).
Fix NoMethodError for malformed multiparameter attribute keys
Raise ActiveRecord::MultiparameterAssignmentErrors when assigning a malformed multiparameter attribute name.
Allow create_join_table to accept a primary key
This is useful for databases like PostgreSQL where logical replication requires primary keys on all tables.
Fix crash when trying to attach a Blob to a Record
Prevent ActiveStorage.touch_attachment_records = false from crashing the attachment of a Blob.
Respect reject in Action Cable before_subscribe callbacks
It doesn’t call subscribed if a before_subscribe callback calls reject.
