rails/actionpack/CHANGELOG.md

• 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
