rails--rails/actionpack/CHANGELOG.md

• Exclude additional flash types from ActionController::Base.action_methods.

  Ensures that additional flash types defined on ActionController::Base subclasses are not listed as actions on that controller.

  class MyController < ApplicationController
    add_flash_types :hype
  end
  
  MyController.action_methods.include?('hype') # => false

• Deleting an item from the Middleware stack will raise if the item is not found

  Previously, calling config.middleware.delete(ItemNotInMiddleware) would fail silently. Now it will raise, same as config.middleware.move(0, ItemNotInMiddleware) does.

  Alex Ghiculescu

• OpenSSL constants are now used for Digest computations.

  Dirkjan Bussink

• Remove IE6-7-8 file download related hack/fix from ActionController::DataStreaming module

  Due to the age of those versions of IE this fix is no longer relevant, more importantly it creates an edge-case for unexpected Cache-Control headers.

  Tadas Sasnauskas

• Configuration setting to skip logging an uncaught exception backtrace when the exception is present in rescued_responses.

  It may be too noisy to get all backtraces logged for applications that manage uncaught exceptions via rescued_responses and exceptions_app. config.action_dispatch.log_rescued_responses (defaults to true) can be set to false in this case, so that only exceptions not found in rescued_responses will be logged.

  Alexander Azarov, Mike Dalessio

• Ignore file fixtures on db:fixtures:load

  Kevin Sjöberg

• Fix ActionController::Live controller test deadlocks by removing the body buffer size limit for tests.

  Dylan Thacker-Smith

• New ActionController::ConditionalGet#no_store method to set HTTP cache control no-store directive.

  Tadas Sasnauskas

• Drop support for the SERVER_ADDR header

  Following up https://github.com/rack/rack/pull/1573 and https://github.com/rails/rails/pull/42349

  Ricardo Díaz

• Set session options when initializing a basic session.

  Gannon McGibbon

• Add cache_control: {} option to fresh_when and stale?

  Works as a shortcut to set response.cache_control with the above methods.

  Jacopo Beschi

• Writing into a disabled session will now raise an error.

  Previously when no session store was set, writing into the session would silently fail.

  Jean Boussier

• Add support for 'require-trusted-types-for' and 'trusted-types' headers.

  Fixes #42034

  lfalcao

• Remove inline styles and address basic accessibility issues on rescue templates.

  Jacob Herrington

• Add support for 'private, no-store' Cache-Control headers.

  Previously, 'no-store' was exclusive; no other directives could be specified.

  Alex Smith

• Expand payload of unpermitted_parameters.action_controller instrumentation to allow subscribers to know which controller action received unpermitted parameters.

  bbuchalter

• Add ActionController::Live#send_stream that makes it more convenient to send generated streams:

  send_stream(filename: "subscribers.csv") do |stream|
    stream.writeln "email_address,updated_at"
  
    @subscribers.find_each do |subscriber|
      stream.writeln [ subscriber.email_address, subscriber.updated_at ].join(",")
    end
  end
  

  DHH

• Add ActionController::Live::Buffer#writeln to write a line to the stream with a newline included.

  DHH

• ActionDispatch::Request#content_type now returned Content-Type header as it is.

  Previously, ActionDispatch::Request#content_type returned value does NOT contain charset part. This behavior changed to returned Content-Type header containing charset part as it is.

  If you want just MIME type, please use ActionDispatch::Request#media_type instead.

  Before:

  request = ActionDispatch::Request.new("CONTENT_TYPE" => "text/csv; header=present; charset=utf-16", "REQUEST_METHOD" => "GET")
  request.content_type #=> "text/csv"
  

  After:

  request = ActionDispatch::Request.new("Content-Type" => "text/csv; header=present; charset=utf-16", "REQUEST_METHOD" => "GET")
  request.content_type #=> "text/csv; header=present; charset=utf-16"
  request.media_type   #=> "text/csv"
  

  Rafael Mendonça França

• Change ActionDispatch::Request#media_type to return nil when the request don't have a Content-Type header.

  Rafael Mendonça França

• Fix error in ActionController::LogSubscriber that would happen when throwing inside a controller action.

  Janko Marohnić

• Allow anything with #to_str (like Addressable::URI) as a redirect_to location

  ojab

• Change the request method to a GET when passing failed requests down to config.exceptions_app.

  Alex Robbin

• Deprecate the ability to assign a single value to config.action_dispatch.trusted_proxies as RemoteIp middleware behaves inconsistently depending on whether this is configured with a single value or an enumerable.

  Fixes #40772

  Christian Sutter

• Add redirect_back_or_to(fallback_location, **) as a more aesthetically pleasing version of redirect_back fallback_location:, **. The old method name is retained without explicit deprecation.
