Raises exception when respond_to called multiple times in incompatible way

Nesting respond_to calls can lead to unexpected behavior, so it should be
avoided. Currently, the first respond_to format match sets the content-type
for the resulting response. But, if a nested respond_to occurs, it is possible
to match on a different format. For example:
respond_to do |outer_type|
outer_type.js do
respond_to do |inner_type|
inner_type.html { render body: "HTML" }
end
end
end
Browsers will often include */* in their Accept headers. In the above example,
such a request would result in the outer_type.js match setting the content-
type of the response to text/javascript, while the inner_type.html match will
cause the actual response to return "HTML".
This change tries to minimize potential breakage by only raising an exception
if the nested respond_to calls are in conflict with each other. So, something
like the following example would not raise an exception:
respond_to do |outer_type|
outer_type.js do
respond_to do |inner_type|
inner_type.js { render body: "JS" }
end
end
end
While the above is nested, it doesn't affect the content-type of the response.

* Add implicit to path conversion to uploaded file
Ruby has a few implicit conversion protocols (e.g. `to_hash`, `to_str`,
`to_path`, etc.). These are considered implicit conversion protocols
because in certain instances Ruby (MRI core objects) will check if an
argument responds to the appropriate protocol and automatically convert
it when it does; this is why you can provide a `Pathname` instance into
`File.read` without having to explicitly call `to_s`.
```ruby
a_file_path = 'some/path/file.ext'
File.write a_file_path, 'String Path Content'
File.read a_file_path
a_pathname = Pathname(a_file_path)
File.write core_file, 'Pathname Content'
File.read a_file_path
core_file = File.new(a_pathname)
File.write core_file, 'File Content'
File.read core_file
tmp_file = Tempfile.new('example')
File.write tmp_file, 'Tempfile Content'
File.read tmp_file
```
So how does an uploaded file work in such cases?
```ruby
tmp_file = Tempfile.new('example')
File.write tmp_file, 'Uploaded Content'
uploaded_file = ActionDispatch::Http::UploadedFile.new(tempfile: tmp_file)
File.read uploaded_file
```
It fails with a `TypeError`:
no implicit conversion of ActionDispatch::Http::UploadedFile into String
In order to make an uploaded file work it must be explicitly converted
to a file path using `path`.
```ruby
File.read uploaded_file.path
```
This requires any code that expects path/file like objects to either
special case an uploaded file, re-implement the path conversion protocol
to use `path`, or forces the developer to explicitly cast uploaded files
to paths. This last option can sometimes be difficult to do when such
calls are deep within the inner workings of libraries.
Since an uploaded file already has a path it makes sense to implement
the implicit "path" conversion protocol (just like `File` and
`Tempfile`). This change allows uploaded file content to be treated more
closely to regular file content, without requiring any special case
handling or explicit conversion for common file utilities.
* Note uploaded file path delegation in CHANGELOG

When a `get` method called with `as: :json` and `params: nil` or
`params: false` (explicitly or implicitly)
`RequestEncoder#encode_params` converts it into a `null` or `false`
value which includes a unexpected `null=` or `false` query string into
request URL. From now on `RequestEncoder#encode_params` checks whether
`params` is nil or not otherwise returns.

- There was an issue inside controller tests where order params were not respected, the reason
was because we were calling `Hash#to_query` which sorts the results lexicographically.
1e4e1b62 fixed that issue by not using `to_query` but instead a utility function provided by rack.
- However with the fix came another issue where it's now no longer possible to do this
```
post :foo, params: { user: User.first }
# Prior to the patch the controller will receive { "user" => "1" }
# Whereas now you get { "user": "#<User: ...>" }
```
The fix in this PR is to modify `Hash#to_query` to sort only when it
doesn't contain an array structure that looks something like "bar[]"

* Allow get arguments for follow_redirect
Now all arguments passed to `follow_redirect!` are passed to the
underlying `get` method. This for example allows to set custom headers
for the redirection request to the server.
This is especially useful for setting headers that may, outside of the
testing environment, be set automatically on every request, i.e. by a
web application firewall.

From <https://tools.ietf.org/html/rfc5861>:
> The stale-if-error HTTP Cache-Control extension allows a cache to
> return a stale response when an error -- e.g., a 500 Internal Server
> Error, a network segment, or DNS failure -- is encountered, rather
> than returning a "hard" error. This improves availability.
>
> The stale-while-revalidate HTTP Cache-Control extension allows a
> cache to immediately return a stale response while it revalidates it
> in the background, thereby hiding latency (both in the network and on
> the server) from clients.
These are useful, fully standardized parts of the HTTP protocol with
widespread support among CDN vendors. Supporting them will make it
easier to utilize reverse proxies and CDNs from Rails.

Journey's scanner tokenizes the `|` (:OR) operator when scanning route
urls such as `"/:foo|*bar"`. However, the current scanner test does not
have any test cases for the `|` operator. This commit adds a test case

`to_query` sorts parameters before encoding them. This causes a round
tripping issue as noted here:
https://github.com/rails/rails/issues/23997#issuecomment-328297933
https://github.com/rails/rails/issues/10529#issuecomment-328298109
https://github.com/rails/rails/pull/30558
Unfortunately, that method is being used to generate cache keys, so its
results need to be stable:
https://github.com/rails/rails/commit/10dec0e65e1f4d87f411b4361045eba86b121be9
However, the test harness is only using `to_query` to encode parameters
before sending them to the controller so the "cache key" usecase doesn't
apply here.
This commit adds a test that demonstrates the round trip problems and
changes the serialization strategy to use Rack for encoding the
parameters rather than `to_query`.

If a POST request is followed by a GET request in a controller test, the
`rack.input` and `RAW_POST_DATA` headers from the first request will be
reset but the `CONTENT_LENGTH` header will leak, leading the request
object in the second request to incorrectly believe it has a body.

`RAW_POST_DATA` is derived from the `rack.input` header, which changes
with each test request. It needs to be cleared in `scrub_env!`, or all
requests within the same test will see the value from the first request.

Plugins interacting with the exceptions caught and displayed by
ActionDispatch::DebugExceptions currently have to monkey patch it to get
the much needed exception for their calculation.
With DebugExceptions.register_interceptor, plugin authors can hook into
DebugExceptions and process the exception, before being rendered. They
can store it into the request and process it on the way back of the
middleware chain execution or act on it straight in the interceptor.
The interceptors can be play blocks, procs, lambdas or any object that
responds to `#call`.

Fixes StrongParameters `permit!` to work with nested arrays

`permit!` is intended to mark all instances of `ActionController::Parameters` as permitted, however nested arrays of params were not being marked permitted because the method did shallow iteration.
This fixes that by flattening the array before calling `permit!` on all each item.

### Summary
The `session` object is not a real Hash but responds to many methods of Hash
such as `[]`, `[]`, `fetch`, `has_key?`.
Since Ruby 2.3, Hash also supports a `dig` method.
This commit adds a `dig` method to `ActionDispatch::Request::Session` with the
same behavior as `Hash#dig`.
This is useful if you store a hash in your session, such as:
```ruby
session[:user] = { id: 1, avatar_url: "http://example.org/nyancat.jpg" }
```
Then you can shorten your code from `session[:user][:avatar_url]` to `session.dig :user, :avatar_url`.
### Other Information
I cherry-picked a commit from https://github.com/rails/rails/pull/23864, and modify a bit.
The changes are below:
* Converts only the first key to a string adjust to the `fetch` method.
* Fixes a test case because we cannot use the indifferent access since ee5b621e2f8fde380ea4bc75b0b9d6f98499f511.

Make mutating params#dig return value mutate underlying params

| | |
| | |
| | |
| | |

When #dig was called on a params object and return either a Hash or an
Array, and that value was subsquently mutated, it would not modify the
containing params object. That means that the behavior of
`params.dig(:a, :b)[:c] = 1` did not match either `params[:a][:b][:c] =
1` nor `hash.dig(:a, :b)[:c] = 1`. Similarly to
`ActionController::Parameters#[]`, use `#convert_hashes_to_parameters`
to pre-convert values and insert them in the receiving params object
prior to returning them.

Today there are two common ways for Rails developers to force their
applications to communicate over HTTPS:
* `config.force_ssl` is a setting in environment configurations that
enables the `ActionDispatch::SSL` middleware. With this middleware
enabled, all HTTP communication to your application will be redirected
to HTTPS. The middleware also takes care of other best practices by
setting HSTS headers, upgrading all cookies to secure only, etc.
* The `force_ssl` controller method redirects HTTP requests to certain
controllers to HTTPS.
As a consultant, I've seen many applications with misconfigured HTTPS
setups due to developers adding `force_ssl` to `ApplicationController`
and not enabling `config.force_ssl`. With this configuration, many
application requests can be served over HTTP such as assets, requests
that hit mounted engines, etc. In addition, because cookies are not
upgraded to secure only in this configuration and HSTS headers are not
set, it's possible for cookies that are meant to be secure to be sent
over HTTP.
The confusion between these two methods of forcing HTTPS is compounded
by the fact that they share an identical name. This makes finding
documentation on the "right" method confusing.
HTTPS throughout is quickly becomming table stakes for all web sites.
Sites are expected to operate over HTTPS for all communication,
sensitive or otherwise. Let's encourage use of the broader-reaching
`ActionDispatch::SSL` middleware and elminate this source of user
confusion. If, for some reason, applications need to expose certain
endpoints over HTTP they can do so by properly configuring
`config.ssl_options`.
