Hi, it’s Emmanuel Hayford. Here’s a look at the highlights from this week’s updates to the Rails codebase.
Allow retry_on wait procs to accept error as a second argument
This PR adds support for retry_on wait procs to optionally receive the error as a second argument, enabling dynamic retry strategies based on error properties.
class RemoteServiceJob < ActiveJob::Base
retry_on CustomError, wait: ->(executions, error) { error.retry_after || executions * 2 }
def perform
# ...
end
end
Procs with arity 0 or 1 continue to receive only the execution count, maintaining backwards compatibility.
Make CSRF header-only protection compatible with local installs using HTTP
This change allows requests with missing Sec-Fetch-Site headers if they happen over HTTP and the app is not configured to force SSL. The Origin check always happens in any case.
Remove X-XSS-Protection from default headers
The X-XSS-Protection header has been removed from the default headers as modern browsers no longer support it.
Deprecate protect_from_forgery without explicit strategy
When protect_from_forgery is called without arguments, it defaults to :null_session. However, when config.action_controller.default_protect_from_forgery is enabled, it uses :exception. This inconsistency is now deprecated to encourage explicit strategy declaration.
Wrap setting ActionController::Live config in load hook
This change wraps the ActionController::Live configuration setting in a load hook, ensuring proper initialization timing.
Add PostgreSQLAdapter.register_type_mapping
Gems adding types to PostgreSQL (like PostGIS or pgvector) previously had to monkey-patch the adapter. This PR adds a cleaner public interface for registering custom type mappings.
Override inspect in Combined, Env & Encrypted Configurations
Previously, inspecting configuration objects would expose all sensitive data including ENV variables and credentials. Now only key names are shown:
# Before
Rails.app.creds
#<ActiveSupport::CombinedConfiguration:0x... @configurations=[... "SOME_SECRET" => "secret_value" ...]>
# After
Rails.app.creds
#<ActiveSupport::CombinedConfiguration:0x... keys=[:rails_env, :some_secret, :secret_key_base]>
Memoize IAM client and set authorization to ADC for GCS Active Storage service
This PR restores the previous behaviour where Application Default Credentials (ADC) is used when iam: true is set, while avoiding excessive ADC calls by memoizing the client. Calls are only made at instantiation time and when credentials expire.
Make ActiveStorage::Service responsible for checksums
S3, GCS, and Azure all support file integrity checksums beyond MD5, which cannot be used in FIPS-compliant environments. This PR moves checksum calculation to the storage service class, enabling support for additional algorithms like SHA256 for the S3 service, including direct uploads.
Deprecate built-in ActiveJob backburner adapter
As part of the ongoing cleanup of legacy adapters from Active Job, the built-in Backburner adapter has been deprecated.
