Move the Journey code underneath the ActionDispatch namespace so
that we don't pollute the global namespace with names that may
be used for models.

Fixes rails/journey#49.

Removes support for :encode, :replace_at, and :replace_dot
options from the mail_to helper. Support for these options
has been extracted to the 'actionview-encoded_mail_to' gem.

cache_if(condition, option, &block) and cache_unless(condition, option, &block).

In the PR #8371 was introduced  conditional options :if and :unless in
the cache method.

    Example:

      <%= cache @model, if: some_condition(@model) do %>
        ...
      <%end%>

This is a good feature but *cache_if* and and *cache_unless*
are more concise and close to the standard of rails view helpers
(ex: link_to_if and link_to_unless).

    Example:

      <%= cache_if condition, @model do %>
      ...
      <%end%>

Remove all the old url helper methods when clear! is called on the
route set because it's possible that some routes have been removed.

If env['RAW_POST_DATA'] is nil, #raw_post will attempt to set it to
the result of #body (which will return env['rack.input'] if
env['RAW_POST_DATA'] is nil). #raw_post will then attempt to rewind
the result of another call to #body. Since env['RAW_POST_DATA'] has
already been set, the result of #body is not env['rack.input'] anymore.
This causes env['rack.input'] to never be rewound.

Such request can happen on Internet Explorer. When we redirect
after multipart form submission, the request type is changed
to GET, but Content-Type is preserved as multipart. GET request
cannot have multipart body and that caused Rails to fail.

It's similar fix to Rack's one:
https://github.com/chneukirchen/rack/blob/8025a4ae9477d1e6231344c2b7d795aa9b3717b6/lib/rack/request.rb#L224

This reverts commit c59734f7.

This commit inverts the precedence in ActionDispatch::Static so that
dynamic content will be served before static content. This is so that
precompiled assets do not inadvertently get included when running in
development mode - it should have no effect in production where static
files are usually handled by the web server.

Closes #6421

be ignored. A regular expression constraint gets overwritten when the
routes.rb file is processed. Changed the overwriting to an ||= instead
of an = assignment.

Override <%== to always behave as literal text rather than toggling based on whether escaping is enabled. Fixes that existing plaintext email templates using <%== unexpectedly flipped to *escaping* HTML when #8235 was merged.

Move the routes for each test inside the test method so that
it's easier to see which routes are applicable to which test.

To ensure that each test wasn't invalidated the changes were
done by first removing all of the routes, ensuring that all
of the tests failed and then adding the routes back to each
test one by one. One test for `assert_recognizes` was
removed as it wasn't actually testing the defined routes and
is now tested more thoroughly in routing_assertions_test.rb.

One downside is that the test suite takes about 1s longer
due to having to using `method_missing` for handling the url
helpers as using `include url_helpers` isn't isolated
for each test.

This add support for sending an explicit opt-out of the "Russian-doll"
cache digest feature on a case-by-case basis. This is useful when cache-
expiration needs to be performed manually and it would be otherwise
difficult to know the exact name of a digested cache key.

For instance, it prevents false positive in this case:

    file = nil
    get :index
    assert_template("#{file}")

Was surprising found that this example doesn't work:

  scope :api do
    resources :users
  end

and the right form to use it is:

  scope 'api' do
    resources :users
  end

I think this should work similary as `namespace` where both are allowed.
These two are equivalent:

  namespace :api do
    resources :users
  end

  namespace 'api' do
    resources :user
  end

Merge url for tests and add changelog entry for #8233.

With a "params" argument, the following error is raised:

    undefined method `reject!` for "":String

This resolves issues when rendering nested partials.
Previously the `PartialRenderer` was reused which led to
situations where the state of the renderer was reset.

Closes #8197

Introduced in 4a4de567.

This is a list of mime types where template text is not html escaped
by default. It prevents `Jack & Joe` from rendering as
`Jack & Joe` for the whitelisted mime types. The default whitelist
contains text/plain.

This follows a whitelist approach where plain text templates are
not escaped, and all the others (json, xml) are. The mime type is
assumed to be set by the abstract controller.
