• Include the content of the flash in the auto-generated etag. This solves the following problem:

  1. POST /messages
  2. redirect_to messages_url, notice: 'Message was created'
  3. GET /messages/1
  4. GET /messages

  Step 4 would before still include the flash message, even though it's no longer relevant, because the etag cache was recorded with the flash in place and didn't change when it was gone.

• SSL: Changes redirect behavior for all non-GET and non-HEAD requests (like POST/PUT/PATCH etc) to http:// resources to redirect to https:// with a 307 status code instead of 301 status code.

  307 status code instructs the HTTP clients to preserve the original request method while redirecting. It has been part of HTTP RFC since 1999 and is implemented/recognized by most (if not all) user agents.

  # Before
  POST http://example.com/articles (i.e. ArticlesContoller#create)
  redirects to
  GET https://example.com/articles (i.e. ArticlesContoller#index)
  
  # After
  POST http://example.com/articles (i.e. ArticlesContoller#create)
  redirects to
  POST https://example.com/articles (i.e. ArticlesContoller#create)

• Add :as option to ActionController:TestCase#process and related methods.

  Specifying as: mime_type allows the CONTENT_TYPE header to be specified in controller tests without manually doing this through @request.headers['CONTENT_TYPE'].

• Show cache hits and misses when rendering partials.

  Partials using the cache helper will show whether a render hit or missed the cache:

  Rendered messages/_message.html.erb in 1.2 ms [cache hit]
  Rendered recordings/threads/_thread.html.erb in 1.5 ms [cache miss]
  

  This removes the need for the old fragment cache logging:

  Read fragment views/v1/2914079/v1/2914079/recordings/70182313-20160225015037000000/d0bdf2974e1ef6d31685c3b392ad0b74 (0.6ms)
  Rendered messages/_message.html.erb in 1.2 ms [cache hit]
  Write fragment views/v1/2914079/v1/2914079/recordings/70182313-20160225015037000000/3b4e249ac9d168c617e32e84b99218b5 (1.1ms)
  Rendered recordings/threads/_thread.html.erb in 1.5 ms [cache miss]
  

  Though that full output can be reenabled with config.action_controller.enable_fragment_cache_logging = true.

• Don't override the Accept header in integration tests when called with xhr: true.

  Fixes #25859.

  David Chen

• Fix defaults option for root route.

  A regression from some refactoring for the 5.0 release, this change fixes the use of defaults (default parameters) in the root routing method.

  Chris Arcand

• Check request.path_parameters encoding at the point they're set.

  Check for any non-UTF8 characters in path parameters at the point they're set in env. Previously they were checked for when used to get a controller class, but this meant routes that went directly to a Rack app, or skipped controller instantiation for some other reason, had to defend against non-UTF8 characters themselves.

• Don't raise ActionController::UnknownHttpMethod from ActionDispatch::Static.

  Pass Rack::Request objects to ActionDispatch::FileHandler to avoid it raising ActionController::UnknownHttpMethod. If an unknown method is passed, it should pass exception higher in the stack instead, once we've had a chance to define exception handling behaviour.

  Grey Baker

• Handle Rack::QueryParser errors in ActionDispatch::ExceptionWrapper.

  Updated ActionDispatch::ExceptionWrapper to handle the Rack 2.0 namespace for ParameterTypeError and InvalidParameterError errors.
