rails--rails/railties/test/log_subscriber_test.rb
Justin George 731d4392e4 Change event namespace ordering to most-significant first [#4504 state:resolved]
More work still needs to be done on some of these names
(render_template.action_view and render_template!.action_view particularly)
but this allows (for example) /^sql/ to subscribe to all
the various ORMs without further modification
