rails/actionpack/CHANGELOG.md

• Deprecate poltergeist and webkit (capybara-webkit) driver registration for system testing (they will be removed in Rails 7.1). Add cuprite instead.

  Poltergeist and capybara-webkit are already not maintained. These usage in Rails are removed for avoiding confusing users.

  Cuprite is a good alternative to Poltergeist. Some guide descriptions are replaced from Poltergeist to Cuprite.

  Yusuke Iwaki

• Add Middleware#remove to delete middleware or raise if not found.

  Middleware#remove works just like Middleware#delete but will raise an error if the middleware isn't found.

  Alex Ghiculescu, Petrik de Heus

• 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
  

  Gavin Morrice

• 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.
