Previously if you were looking for a given key, the header may incorrectly tell you that it did not exist even though it would return a valid value:
```ruby
env = { "CONTENT_TYPE" => "text/plain" }
headers = ActionDispatch::Http::Headers.new(env)
headers["Content-Type"]
# => "text/plain"
headers.key?("Content-Type")
# => false
```
This PR fixes that behavior by converting the key before checking for presence

When requesting a controller with the following code with a unknown format:
def my_action
respond_to do |format|
format.json { head :ok }
format.any { render text: 'Default response' }
end
end
we should render the default response instead of raising ActionController::UnknownFormat

avoid freezing the headers until the web server has actually read data
from the body proxy. Once the webserver has read data, then we should
throw an error if someone tries to set a header

when streaming responses, we need to make sure the cookie jar is written
to the headers before returning up the stack. This commit introduces a
new method on the response object that writes the cookie jar to the
headers as the response is committed. The middleware and test framework
will not write the cookie headers if the response has already been
committed.

`render :body` should just not set the `Content-Type` header. By
removing the header, it breaks the compatibility with other parts.
After this commit, `render :body` will returns `text/html` content type,
sets by default from `ActionDispatch::Response`, and it will preserve
the overridden content type if you override it.
Fixes #14197, #14238
This partially reverts commit 3047376870d4a7adc7ff15c3cb4852e073c8f1da.

Setting this attribute to `true` will remove the content type header
from the request. This is use in `render :body` feature.

This is an option for sending a raw content back to browser. Note that
this rendering option will unset the default content type and does not
include "Content-Type" header back in the response.
You should only use this option if you are expecting the "Content-Type"
header to not be set. More information on "Content-Type" header can be
found on RFC 2616, section 7.2.1.
Please see #12374 for more detail.

Allow setting `request.variant` as an array - an order in which they will be
rendered.
For example:
request.variant = [:tablet, :phone]
respond_to do |format|
format.html.none
format.html.phone # this gets rendered
end
|
| |
|
|
|
|
| |
Returning `self` from within the array returned by `to_ary`
caused this. Instead, we can just substitute another object.
It provides the `each` behavior required by the rack spec.

TLDR: always return an object that responds to the query methods from
request.format, and do not touch Mime::Type[] lookup to avoid bugs.
---
Long version:
The initial issue was about being able to do checks like
request.format.html? for request with an unknown format, where
request.format would be nil.
This is where the issue came from at first in #7837 and #8085
(merged in cba05887dc3b56a46a9fe2779b6b228880b49622), but the
implementation went down the path of adding this to the mime type
lookup logic.
This unfortunately introduced subtle bugs, for instance in the merged
commit a test related to send_file had to be changed to accomodate the
introduction of the NullType.
Later another bug was found in #13064, related to the content-type being
shown as #<Mime::NullType:...> for templates with localized extensions
but no format included. This one was fixed in #13133, merged in
43962d6ec50f918c9970bd3cd4b6ee5c7f7426ed.
Besides that, custom handlers were not receiving the proper template
formats anymore when passing through the rendering process, because of
the NullType addition. That was found while migrating an application
from 3.2 to 4.0 that uses the Markerb gem (a custom handler that
generates both text and html emails from a markdown template).
---
This changes the implementation moving away from returning this null
object from the mime lookup, and still fixes the initial issue where
request.format.zomg? would raise an exception for unknown formats due to
request.format being nil.

Return Nil is implicit in a method and this syntax is used in the others

By default, variants in the templates will be picked up if a variant is set
and there's a match. The format will be:
app/views/projects/show.html.erb
app/views/projects/show.html+tablet.erb
app/views/projects/show.html+phone.erb
If request.variant = :tablet is set, we'll automatically be rendering the
html+tablet template.
In the controller, we can also tailer to the variants with this syntax:
class ProjectsController < ActionController::Base
def show
respond_to do |format|
format.html do |html|
@stars = @project.stars
html.tablet { @notifications = @project.notifications }
html.phone { @chat_heads = @project.chat_heads }
end
format.js
format.atom
end
end
end
The variant itself is nil by default, but can be set in before filters, like
so:
class ApplicationController < ActionController::Base
before_action do
if request.user_agent =~ /iPad/
request.variant = :tablet
end
end
end
This is modeled loosely on custom mime types, but it's specifically not
intended to be used together. If you're going to make a custom mime type,
you don't need a variant. Variants are for variations on a single mime
types.

The previous implementation of this functionality could be accidentally
subverted by instantiating a raw Rack::Request before the first Rails::Request

After some discussion on Twitter with @skud, the documentation on ActionDispatch::Response is
a bit sparse. This class is useful when you're writing tests, as often you want to assert various
things about the response that's coming back. Better docs would make this easier for people new
to testing in Rails.
I only added some descriptions for various properties that were defined, and mostly just a sentence
or two. Most of these things are familliar if you're working with HTTP, but some words is better
than no words at all.
Hopefully further commits will fix up things that aren't just documentation.

ActionDispatch::Request#deep_munge was introduced as a private method,
but was turned into a public one for the use of
ActionDispatch::ParamsParser.
I have extracted it into ActionDispatch::Request::Utils, so it does not
get mixed up with the Request public methods.
