This actually runs a request through the system, using the actual
routing methods as we would use in production, then tests the
path_parameters set on the request object. The `recognize_path` method
isn't actually used in production, so testing what it returns isn't
useful.
`ActionDispatch::ShowExceptions` overwrites `PATH_INFO` with the status code
for the exception defined in `ExceptionWrapper`, so the path the user was
visiting when an exception occurred was not previously available to any custom
exceptions_app.
The original `PATH_INFO` is now stashed in
`env["action_dispatch.original_path"]`.
Although the cookie values happens to be ASCII strings because they are
Base64 encoded, it is semantically incorrect to check for the number of the
characters in the cookie, when we actually want to check for the number of the
bytes it consists of.
Furthermore it is unecessary coupling with the current implementation that
uses Base64 for encoding the values.
`render nothing: true` or rendering a `nil` body no longer add a single
space to the response body.
The old behavior was added as a workaround for a bug in an early version of
Safari, where the HTTP headers are not returned correctly if the response
body has a 0-length. This is been fixed since and the workaround is no
longer necessary.
Use `render body: ' '` if the old behavior is desired.
Because URI paths may contain non US-ASCII characters we need to force
the encoding of any unescaped URIs to UTF-8 if they are US-ASCII.
This essentially replicates the functionality of the monkey patch to
URI.parser.unescape in active_support/core_ext/uri.rb.
Fixes#16104.
Prior to this commit shallow resources would only generate paths for
non-direct children (with a nested depth greater than 1).
Take the following routes file.
resources :blogs do
resources :posts, shallow: true do
resources :comments do
resources :tags
end
end
end
This would generate shallow paths for `tags` nested under `posts`,
e.g `/posts/:id/tags/`, however it would not generate shallow paths
for `comments` nested under `posts`, e.g `/posts/:id/comments/new`.
This commit changes the behaviour of the route mapper so that it
generate paths for direct children of shallow resources, for example
if you take the previous routes file, this will now generate
shallow paths for `comments` nested under `posts`, .e.g
`posts/:id/comments/new`.
This was the behaviour in Rails `4.0.4` however this was broken in
@jcoglan's fix for another routes related issue[1].
This also fixes an issue[2] reported by @smdern.

The latter has the same speed as the former in the worst case
and faster in general, because it is always better to sort less items.
Unfortunately, `routes.select!{...}.sort_by!{...}` is not possible here
because `select!` returns `nil`, so select! and sort! must be done
in two steps.
Because it is more natural way to test substring inclusion. Also, in
this particular case it is much faster.
In general, using `Regexp.new str` for such kind of things is dangerous.
The string must be escaped, unless you know what you're doing. Example:
Regexp.new "\\" # HELLO WINDOWS
# RegexpError: too short escape sequence: /\/
The right way to do this is escape the string
Regexp.new Regexp.escape "\\"
# => /\\/
Here is the benchmark showing how faster `include?` call is.
```
require 'benchmark/ips'
Benchmark.ips do |x|
x.report('include?') { !"index".to_s.include? File::SEPARATOR }
x.report(' !~ ') { "index" !~ Regexp.new(File::SEPARATOR) }
end
__END__
Calculating -------------------------------------
include? 75754 i/100ms
!~ 21089 i/100ms
-------------------------------------------------
include? 3172882.3 (±4.5%) i/s - 15832586 in 5.000659s
!~ 322918.8 (±8.6%) i/s - 1602764 in 4.999509s
```
Extra `.to_s` call is needed to handle the case when `action_name` is
`nil`. If it is omitted, some tests fail.
