with_routing. This only affects our internal AP tests.

It was severely broken since it was ported to NewBase and is causing problems with normal exception catching. A replacement is coming soon.

This commit breaks all exception catching plugins like ExceptionNotifier. These plugins should be rewritten as middleware instead overriding Controller#rescue_action_in_public.

Memoize request accessors on the Rack env so other request objects have access to the same cache [#1668 state:resolved]

Signed-off-by: NJoshua Peek <josh@joshpeek.com>

Added ActiveSupport::BacktraceCleaner and Rails::BacktraceCleaner for cutting down on backtrace noise (inspired by the Thoughtbot Quiet Backtrace plugin) [DHH]

Note : If you're not using rescue_from, you should overrider rescue_action_without_handler() method
and not rescue_action(). Afterwards, you can set request.remote_addr to a non "0.0.0.0" value for testing the
overridden behavior.

Added Rails.public_path to control where HTML and assets are expected to be loaded from (defaults to Rails.root + "/public") #11581 [nicksieger]

Introduce ActionController::Base.rescue_from to declare exception-handling methods. Cleaner style than the case-heavy rescue_action_in_public. Closes #9449.

Make sure missing template exceptions actually say which template they were looking for.  Closes #8683 [dasil003]

Routing: respond with 405 Method Not Allowed status when the route path matches but the HTTP method does not. Closes #6953.

Added .erb and .builder as preferred aliases to the now deprecated .rhtml and .rxml extensions [Chad Fowler]. This is done to separate the renderer from the mime type. .erb templates are often used to render emails, atom, csv, whatever. So labeling them .rhtml doesn't make too much sense. The same goes for .rxml, which can be used to build everything from HTML to Atom to whatever. .rhtml and .rxml will continue to work until Rails 3.0, though. So this is a slow phasing out. All generators and examples will start using the new aliases, though.
