Problem description (quoted from @rafaelfranca's excellent explanation in https://github.com/rails/jquery-ujs/issues/318#issuecomment-88129005):
> Let say that we requested /tasks/1 using Ajax, and the previous page has the same url. When we click the back button the browser tries to get the response from its cache and it gets the javascript response. With vary we "fix" this behavior because we are telling the browser that the url is the same but it is not from the same type what will skip the cache.
And there's a Rails issue discussing about this problem as well https://github.com/rails/rails/issues/25842
Also, according to [RFC 7231 7.1.4](https://tools.ietf.org/html/rfc7231#section-7.1.4)
> An origin server SHOULD send a Vary header field when its algorithm
> for selecting a representation varies based on aspects of the request
> message other than the method and request target
we should add `Vary: Accept` header when determining content based on the `Accept` header.
Although adding such header by default could cause unnecessary cache invalidation. But this PR only adds the header if:
- The format param is not provided
- The request is a `xhr` request
- The request has accept headers and the headers are valid
So if the user
- sends request with explicit format, like `/users/1.json`
- or sends a normal request (non xhr)
- or doesn't specify accept headers
then the header won't be added.
See the discussion in https://github.com/rails/rails/issues/25842 and
https://github.com/rails/rails/pull/36213 for more details.

We sometimes say "✂️ newline after `private`" in a code review (e.g.
https://github.com/rails/rails/pull/18546#discussion_r23188776,
https://github.com/rails/rails/pull/34832#discussion_r244847195).
Now `Layout/EmptyLinesAroundAccessModifier` cop have new enforced style
`EnforcedStyle: only_before` (https://github.com/rubocop-hq/rubocop/pull/7059).
That cop and enforced style will reduce the our code review cost.

Since Rails 6.0 will support Ruby 2.4.1 or higher
`# frozen_string_literal: true` magic comment is enough to make string object frozen.
This magic comment is enabled by `Style/FrozenStringLiteralComment` cop.
* Exclude these files not to auto correct false positive `Regexp#freeze`
- 'actionpack/lib/action_dispatch/journey/router/utils.rb'
- 'activerecord/lib/active_record/connection_adapters/sqlite3_adapter.rb'
It has been fixed by https://github.com/rubocop-hq/rubocop/pull/6333
Once the newer version of RuboCop released and available at Code Climate these exclude entries should be removed.
* Replace `String#freeze` with `String#-@` manually if explicit frozen string objects are required

ActiveStorage::BaseController subclasses ActionController::Base.
ActionController::Base has an "inherited" hook set that includes the
routing helpers to any subclass of AC::Base. Since
ActiveStorage::BaseController is a subclass of AC::Base, it will get
routing helpers included automatically. Unfortunately, when the
framework is eagerly loaded, ActiveStorage::BaseController is loaded
*before* the applications routes are loaded which means it attempts to
include an "in flight" module so it gets an exception.
This commit allows a class that's interested in being extended with
routing helpers register itself such that when the routes are finalized,
it will get the helpers included. If the routes are already finalized,
then the helpers get included immediately.

Instead of using a splat on the head and tail we can mutate the array by flattening 1 level. We get further savings by not allocating another via `compact` but instead by using `compact!`

Execution of `to_set` below should remove duplicated elements.

Instead of creating new arrays for `uniq` and `map` we can instead modify the array in place.

It is important for users to know that a render or redirect in a "before"
filter causes the action to be cancelled. This was addressed in the guide, but
not the API docs
(http://guides.rubyonrails.org/action_controller_overview.html#filters).

`:api:` tag was removed in 5349f231 since RDoc doesn't support `:api:`
tag. But those methods are not private API, they are public API for
renderers. The renderers should be able to know that they can override
this method.
|

Currently `:api:` tag has leaked on the doc directly since RDoc doesn't
support `:api:` tag directive.
http://api.rubyonrails.org/v5.1/classes/AbstractController/Rendering.html
So `:api: private` doesn't work as expected. We are using `:nodoc:` for
the purpose.
Related #13989.

ActionMailer::Base#instrument_name and
ActionController::Base#instrument_name will be frequently called once
caching is enabled. So it's better to freeze them instead of create new
string on every call.
Also, the instrument name in #instrument_fragment_cache will usually
be "write_fragment.action_controller" or
"read_fragment.action_controller". So freezing them might also gain some
performance improvement. We have done something like this in other places:
https://github.com/rails/rails/blob/master/actionview/lib/action_view/template.rb#L348

Erubi offers the following advantages for Rails:
* Works with ruby's --enable-frozen-string-literal option
* Has 88% smaller memory footprint
* Does no freedom patching (Erubis adds a method to Kernel)
* Has simpler internals (1 file, <150 lines of code)
* Has an open development model (Erubis doesn't have a
public source control repository or bug tracker)
* Is not dead (Erubis hasn't been updated since 2011)
Erubi is a simplified fork of Erubis that contains just the
parts that are generally needed (which includes the parts
that Rails uses). The only intentional difference in
behavior is that it does not include support for <%=== tags
for debug output. That could be added to the ActionView ERB
handler if it is desired.
The Erubis template handler remains in a deprecated state
so that code that accesses it directly does not break. It
can be removed after Rails 5.1.

Provide an API interface similar to how format is handled in
Controllers. In situations where variants are not needed (ex: in
Action Mailer) the method will simply trigger a no-op, and will not
affect end users.

A few have been left for aesthetic reasons, but have made a pass
and removed most of them.
Note that if the method `foo` returns an array, `foo << 1`
is a regular push, nothing to do with assignments, so
no self required.
