Merge `:action` from routing scope and assign endpoint if both `:controller`
and `:action` are present. The endpoint assignment only occurs if there is
no `:to` present in the options hash so should only affect routes using the
shorthand syntax (i.e. endpoint is inferred from the the path).
Fixes#9856
Backport of 37b4276
Backport #9361.
Closes#7554.
This patch determines the `controller#action` directly
in the `match` method when the shorthand syntax is used.
this prevents problems with namespaces and scopes.
Ruby 1.9 freezes Hash string keys by default so where a route is
defined like this:
get 'search' => 'search'
then the Mapper will derive the action from the key. This blows up
later when the action is added to the parameters hash and the
encoding is forced.
Closes#3429
Optional segments with a root scope need to have the leading slash
outside of the parentheses, otherwise the generated url will be empty.
However if the route has non-optional elements then the leading slash
needs to remain inside the parentheses otherwise the generated url
will have two leading slashes, e.g:
Blog::Application.routes.draw do
get '/(:category)', :to => 'posts#index', :as => :root
get '/(:category)/author/:name', :to => 'posts#author', :as => :author
end
$ rake routes
root GET /(:category)(.:format) posts#index
author GET (/:category)/author/:name(.:format) posts#author
This change adds support for optional segments that contain a slash,
allowing support for urls like /page/2 for the root path, e.g:
Blog::Application.routes.draw do
get '/(page/:page)', :to => 'posts#index', :as => :root
end
$ rake routes
root GET /(page/:page)(.:format) posts#index

(cherry picked from commit d8745decaf59aad32aa2f09abdba99b8d0e48b31)
A callable object passed as a constraint for a route may access the request
parameters as part of its check. This causes the combined parameters hash
to be cached in the environment hash. If the constraint fails then any subsequent
access of the request parameters will be against that stale hash.
To fix this we delete the cache after every call to `matches?`. This may have a
negative performance impact if the contraint wraps a large number of routes as the
parameters hash is built by merging GET, POST and path parameters.
Fixes#2510.

This differs from route recognition where first recognized route wins.
This will not be supported in Rails 4.0 so that route recognition and
generation rules are consistent.
After a long list of discussion about the performance problem from using varargs and the reason that we can't find a great pair for it, it would be best to remove support for it for now.
It will come back if we can find a good pair for it. For now, Bon Voyage, `#among?`.
This removes all deprecated classes in ActionController related to
Routing, Abstract Request/Response and Integration/IntegrationTest.
All tests and docs were changed to ActionDispatch instead of ActionController.
