## Rails 4.0.0 (unreleased) ##
+* Fix calculation of `db_runtime` property in
+ `ActiveRecord::Railties::ControllerRuntime#cleanup_view_runtime`.
+ Previously, after raising `ActionView::MissingTemplate`, `db_runtime` was
+ not populated.
+ Fixes #9215.
+
+ *Igor Fedoronchuk*
+
* Do not try to touch invalid (and thus not persisted) parent record
for a `belongs_to :parent, touch: true` association
