Revert "log at debug level what line caused the redirect_to"

This reverts commit 3fa00070047b5d019d39e691598ee2890283d052.

Reason: This message is usually not accurate and annoying:

Revert "Merge pull request #8930 from cordawyn/ordered_railties"

This reverts commit 8348f9ea72c9b50fc4d4462fd9ebe3bba932c783, reversing
changes made to 9dfe2d6f9fabddf9a451a995678a9648c8aaf401.

Reason: this broke railties tests as explained in the issue, and the
author is going to review and report back.

Update guides/source/active_record_validations.md

Duplicated `update`
Raise correct exception now Journey is integrated.

Now that Journey has been integrated into ActionDispatch we can raise
the exception ActionController::UrlGenerationError directly rather than
raising the internal Journey::Router::RoutingError and then have
ActionDispatch::Routing::RouteSet#generate re-raise the exception.
Ensure port is set when passed via the process method
Add support for other types of routing constraints

This now allows the use of arrays like this:

  get '/foo/:action', to: 'foo', constraints: { subdomain: %w[www admin] }

or constraints where the request method returns an Fixnum like this:

  get '/foo', to: 'foo#index', constraints: { port: 8080 }

Note that this only applies to constraints on the request - path
constraints still need to be specified as Regexps as the various
constraints are compiled into a single Regexp.
Change the behavior of route defaults

This commit changes route defaults so that explicit defaults are no
longer required where the key is not part of the path. For example:

  resources :posts, bucket_type: 'posts'

will be required whenever constructing the url from a hash such as a
functional test or using url_for directly. However using the explicit
form alters the behavior so it's not required:

  resources :projects, defaults: { bucket_type: 'projects' }

This changes existing behavior slightly in that any routes which
only differ in their defaults will match the first route rather
than the closest match.

Closes #8814

allow :dirs option for .enumerate

  SourceAnnotationExtractor.enumerate 'TODO|FIXME', dirs: %w(app lib), tag: true
