Closes#21230 by following the indication of @rafaelfranca:
> I think the output change would be simpler.
> What is really important to show is the class of the middleware, so we should change the output to show that.
The configuration for `config.static_cache_control`, and its replacement
`config.public_file_server.headers` are implemented in Railties.
People would configure this in environment files, which is Railties domain too.
When a request is made with AJAX and an error occurs, Rails will render
a text-template for the exception instead of the HTML error page
(#11960).
The `.text.erb` variant of the `_source` template is currently missing,
causing HTML to be rendered in the response. This commit adds the text
template.
To keep the page scannable we only only show the first three source
extracts.
Related to #14745.
Before:
```
~/testing-exceptions ᐅ curl 'http://localhost:3000/' -H
'X-Requested-With: XMLHttpRequest'
RuntimeError in PostsController#index
<div class="source " id="frame-source-0">
<div class="info">
Extracted source (around line <strong>#3</strong>):
</div>
<div class="data">
<table cellpadding="0" cellspacing="0" class="lines">
<tr>
```
After:
```
~/testing-exceptions ᐅ curl 'http://localhost:3000/' -H
'X-Requested-With: XMLHttpRequest'
RuntimeError in PostsController#index
Extracted source (around line #3):
*3 raise
```
It used to behave like this:
url_for(controller: 'x', action: 'y', q: {})
# -> "/x/y?"
We previously avoided empty query strings in most cases by removing
nil values, then checking whether params was empty. But as you can
see above, even non-empty params can yield an empty query string. So
I changed the code to just directly check whether the query string
ended up empty.
(To make everything more consistent, the "removing nil values"
functionality should probably move to ActionPack's Hash#to_query, the
place where empty hashes and arrays get removed. However, this would
change a lot more behavior.)
rather than an action name and *args. The *args were not being used in regular
applications outside tests. This causes a backwards compatibility
issue, but reduces array allocations for most users.
`dispatch` sets the request and response on the controller for us
automatically, so the test harness doesn't need to know the internals of
how request / response is set.

For ActionController::Base we write the cookies in a middleware if it
was not yet committed no matter if the response was committed or not. [1]
For ActionController::Live we write the cookies before the response is
committed. [2]
We already mimic ActionController::Live in
ActionController::TestCase but we don't mimic the ActionController::Base
behavior because we were checking if the response was committed before
writing the cookies.
Now we are matching the behavior of the middleware and writing the
cookies if it was not written before.

This commit follows up of ea9bc06c9a47b839d5e2db94ba6bf7e29c8f0ae9.
To check `@response.content_type.to_s` is ended with `"xml"`,
to use `\z` is sufficient.
Prior to this change, given a route:
# config/routes.rb
get ':a' => "foo#bar"
If one pointed to http://example.com/%BE (param `a` has invalid encoding),
a `BadRequest` would be raised with the following non-informative message:
ActionController::BadRequest
From now on the message displayed is:
Invalid parameter encoding: hi => "\xBE"
Fixes#21923.
When an application has multiple root entries with different
constraints, the current solution is to use `get '/'`. Example:
**Currently I have to do:**
```ruby
get '/', to: 'portfolio#show', constraints: ->(req) { Hostname.portfolio_site?(req.host) }
get '/', to: 'blog#show', constraints: ->(req) { Hostname.blog_site?(req.host) }
root 'landing#show'
```
**But I would like to do:**
```ruby
root 'portfolio#show', constraints: ->(req) { Hostname.portfolio_site?(req.host) }
root 'blog#show', constraints: ->(req) { Hostname.blog_site?(req.host) }
root 'landing#show'
```
Other URL matchers such as `get`, `post`, etc, already allows this, so I
think it's fair that `root` also allow it since it's just a shortcut for
a `get` internally.
When generating the url for a mounted engine through its proxy, the path should be the sum of three parts:
1. Any `SCRIPT_NAME` request header or the value of `ActionDispatch::Routing::RouteSet#relative_url_root`.
2. A prefix (the engine's mounted path).
3. The path of the named route inside the engine.
Since commit 44ff0313c1, this has been broken. Step 2 has been changed to:
2. A prefix (the value of `ActionDispatch::Routing::RouteSet#relative_url_root` + the engine's mounted path).
The value of `ActionDispatch::Routing::RouteSet#relative_url_root` is taken into account in step 1 of the route generation and should be ignored when generating the mounted engine's prefix in step 2.
This commit fixes the regression by having `ActionDispatch::Routing::RouteSet#url_for` check `options[:relative_url_root]` before falling back to `ActionDispatch::Routing::RouteSet#relative_url_root`. The prefix generating code then sets `options[:relative_url_root]` to an empty string. This empty string is used instead of `ActionDispatch::Routing::RouteSet#relative_url_root` and avoids the duplicate `relative_url_root` value in the final result.
This resolves#20920 and resolves#21459
Rails 4.x and earlier didn't support `Mime::Type[:FOO]`, so libraries
that support multiple Rails versions would've had to feature-detect
whether to use `Mime::Type[:FOO]` or `Mime::FOO`.
`Mime[:foo]` has been around for ages to look up registered MIME types
by symbol / extension, though, so libraries and plugins can safely
switch to that without breaking backward- or forward-compatibility.
Note: `Mime::ALL` isn't a real MIME type and isn't registered for lookup
by type or extension, so it's not available as `Mime[:all]`. We use it
internally as a wildcard for `respond_to` negotiation. If you use this
internal constant, continue to reference it with `Mime::ALL`.

Just a slight refactor that delegates file sending to the response
object. This gives us the advantage that if a webserver (in the future)
provides a response object that knows how to do accelerated file
serving, it can implement this method.
* Introduce `ActionDispatch::Http::Headers#add` to add a value to
a multivalued header.
* Move `Response#add_header` upstream: https://github.com/rack/rack/pull/957
* Match upstream `Response#have_header?` -> `#has_header?` name change.
By [this commit](0b476de445)
`Journey::Route#verb` need not to return verb as regexp.
The returned value is used by inspector, so change it to be a string.
Add inspect_with_multiple_verbs test case to keep the behavior of
inspector correctly.
* first test is for `default_charset` i.e `ActionDispatch::Response.default_charset = “utf-8”`
* In below test we are passing `ActionDispatch::Response.default_charset = 'utf-16’` so name of the test is irrelevant — “read content type without charset”
I want to move the header hash to the super request object in order to
consolidate behavior. We should be switching out buffering strategies
rather than header strategies since things like "mutating headers after
send" is an error in both cases (buffering vs streaming).
rather than calling methods on the controller. We should test the
values returned by the controller rather than assuming that the
internals are implemented in a certain way.
I'm making this change so that I can construct response objects that
*don't* have the default headers applied. For example, I would like to
construct a response object from the return value of a controller.
If you need to construct a response object with the default headers,
then please use the alternate constructor:
`ActionDispatch::Response.create`
It doesn't make sense to access the response object before a request is
made (how was a response object created without making a request?) This
commit splits testing default headers and default header mutation tests
and removes access to the pre-request response object.
When the response object is `to_a`'d, that means it's been written to
the socket. It doesn't make sense to mutate the response object after
it's been written (and this may raise an exception in the future).
Changes `Mimes` to compose a set rather than inherit from array. With
this change we don't need to define as many methods, so ISEQ memory is
saved. Also it is clear which methods break the set cache.
We don't want to manage a list of constants on `Mime::`. Managing
constants is strange because it will break method caches, not to mention
looking up by a constant could cause troubles. For example suppose
there is a top level constant `HTML`, but nobody registers the HTML mime
type and someone accesses `Mime::HTML`. Instead of getting an error
about how the mime type doesn't exist, instead you'll get the top level
constant.
So, instead of directly accessing the constants, change this:
Mime::HTML
To this:
Mime::Type[:HTML]
As both `redirect_to_nil` and `redirect_to_params` are raising same `ActionController::ActionControllerError` so it’s good to assert error messages as well
we don't actually need a param parser middleware instance since the
request object will take care of parsing parameters for us. For now,
we'll just configure the parameter parsers on the request in this class.
The middleware stack is a singleton in the application (one instance is
shared for the entire application) which means that there was only one
opportunity to set the parameter parsers. Since there is only one set
of parameter parsers in an app, lets just configure them on the request
class (since that is where they are used).
we need to be more specific about exception handling when dealing with
the parse strategies. The calls to `return yield` can also raise an
exception, but we don't want to handle that in *this* code.
This changes the renderer class to store the controller and defaults as
an instance variable rather than allocating a new class. You can create
a new renderer with an new env by calling `Renderer#new` or use new
defaults by calling `Renderer#with_defaults` and saving the return value
somewhere.
Also I want to keep the `env` private since I would like to change the
keys in the future. This commit only translates particular keys that
the user requested.
In c546a2b this was changed to mimic how the browser behaves in a real
situation but left out types that were registered.
When this was changed it didn't take `text/plain` or `text/html` content
types into account. This is a problem if you're manipulating the
`Content-Type` headers in your controller tests, and expect a certain
result.
The reason I changed this to use `to_sym` is because if the
`Content-Type` is not registered then the symbol will not exist. If it's
one of the special types we handle that specifically (:json, :xml, or
:url_encoded_form). If it's any registered type we handle it by setting
the `path_parameters` and then the `request_parameters`. If the `to_sym`
returns nil an error will be thrown.
If the controller test sets a `Content-Type` on the request that `Content-Type`
should remain in the header and pass along the filename.
For example:
If a test sets a content type on a post
```
@request.headers['CONTENT_TYPE'] = 'text/plain'
post :create, params: { name: 'foo.txt' }
```
Then `foo.txt` should be in the `request_parameters` and params related
to the path should be in the `path_parameters` and the `Content-Type`
header should match the one set in the `@request`. When c546a2b was
committed `text/plain` and `text/html` types were throwing a "Unknown
Content-Type" error which is misleading and incorrect.
Note: this does not affect how this is handled in the browser, just how
the controller tests handle setting `Content-Type`.
If someone sets just a charset, but depends on the implicit type from
rendering, this will store a strange content type header that looks like
this: `; charset=blah`. This is so that when the content type header
is parsed again, it will return nil for the actual type.
