rails--rails/actionpack/CHANGELOG.md

• Separate Action View completely from Action Pack.

  Łukasz Strzałkowski

• Development mode exceptions are rendered in text format in case of XHR request.

  Kir Shatrov

• Fix an issue where :if and :unless controller action procs were being run before checking for the correct action in the :only and :unless options.

  Fixes #11799

  Nicholas Jakobsen

• Fix an issue where assert_dom_equal and assert_dom_not_equal were ignoring the passed failure message argument.

  Fixes #11751

  Ryan McGeary

• Allow REMOTE_ADDR, HTTP_HOST and HTTP_USER_AGENT to be overridden from the environment passed into ActionDispatch::TestRequest.new.

  Fixes #11590

  Andrew White

• Fix an issue where Journey was failing to clear the named routes hash when the routes were reloaded and since it doesn't overwrite existing routes then if a route changed but wasn't renamed it kept the old definition. This was being masked by the optimised url helpers so it only became apparent when passing an options hash to the url helper.

  Andrew White

• Skip routes pointing to a redirect or mounted application when generating urls using an options hash as they aren't relevant and generate incorrect urls.

  Fixes #8018

  Andrew White

• Move MissingHelperError out of the ClassMethods module.

  Yves Senn

• Fix an issue where rails raise exception about missing helper where it should throw LoadError. When helper file exists and only loaded file from this helper does not exist rails should throw LoadError instead of MissingHelperError.

  Piotr Niełacny

• Fix ActionDispatch::ParamsParser#parse_formatted_parameters to rewind body input stream on parsing json params.

  Fixes #11345

  Yuri Bol, Paul Nikitochkin

• Ignore spaces around delimiter in Set-Cookie header.

  Yamagishi Kazutoshi

• Remove deprecated Rails application fallback for integration testing, set ActionDispatch.test_app instead.

  Carlos Antonio da Silva

• Remove deprecated page_cache_extension config.

  Francesco Rodriguez

• Remove deprecated constants from Action Controller:

  ActionController::AbstractRequest  => ActionDispatch::Request
  ActionController::Request          => ActionDispatch::Request
  ActionController::AbstractResponse => ActionDispatch::Response
  ActionController::Response         => ActionDispatch::Response
  ActionController::Routing          => ActionDispatch::Routing
  ActionController::Integration      => ActionDispatch::Integration
  ActionController::IntegrationTest  => ActionDispatch::IntegrationTest
  

  Carlos Antonio da Silva

• Fix Mime::Type.parse when bad accepts header is looked up. Previously it was setting request.formats with an array containing a nil value, which raised an error when setting the controller formats.

  Fixes #10965

  Becker

• Merge :action from routing scope and assign endpoint if both :controller and :action are present. The endpoint assignment only occurs if there is no :to present in the options hash so should only affect routes using the shorthand syntax (i.e. endpoint is inferred from the path).

  Fixes #9856

  Yves Senn, Andrew White

• ActionView extracted from ActionPack

  Piotr Sarnacki, Łukasz Strzałkowski

• Fix removing trailing slash for mounted apps #3215
