Hi, whenever I use rails (on Ubuntu) with ruby -w option, I get lots of warnings, e.g. …/vendor/rails/activerecord/lib/active\_record/validations.rb:313: warning: `*' interpreted as argument prefix .../vendor/rails/activerecord/lib/active_record/callbacks.rb:200: warning: `_’ interpreted as argument prefix …/vendor/rails/activerecord/lib/active\_record/dirty.rb:40: warning: `*' interpreted as argument prefix .../vendor/rails/actionpack/lib/action_controller/routing/ routing_ext.rb:2: warning: method redefined; discarding old to_param .../vendor/rails/actionpack/lib/action_controller/routing/ recognition_optimisation.rb:55: warning: method redefined; discarding old recognize_path .../vendor/rails/actionpack/lib/action_view/base.rb:282: warning: method redefined; discarding old template .../vendor/rails/actionpack/lib/action_view/helpers/ translation_helper.rb:16: warning: `_’ interpreted as argument prefix …/vendor/rails/actionpack/lib/action\_controller/cgi\_ext/session.rb: 24: warning: method redefined; discarding old create\_new\_id …/vendor/rails/actionpack/lib/action\_controller/cgi\_ext/session.rb: 31: warning: method redefined; discarding old initialize …/vendor/rails/actionpack/lib/action\_controller/session/ active\_record\_store.rb:186: warning: method redefined; discarding old connection …/vendor/rails/actionpack/lib/action\_controller/rack\_process.rb:267: warning: `*' interpreted as argument prefix .../vendor/rails/actionpack/lib/action_controller/translation.rb:4: warning: `\*’ interpreted as argument prefix …/vendor/rails/actionpack/lib/action\_controller/translation.rb:9: warning: `*' interpreted as argument prefix .../vendor/rails/activerecord/lib/active_record/observer.rb:35: warning: instance variable @observers not initialized .../vendor/rails/actionpack/lib/action_controller/routing/route_set.rb: 247: warning: instance variable @routes_last_modified not initialized .../vendor/rails/activerecord/lib/active_record/observer.rb:35: warning: instance variable @observers not initialized .../vendor/rails/actionpack/lib/action_view/paths.rb:74: warning: instance variable @loaded not initialized .../vendor/rails/actionpack/lib/action_view/paths.rb:48: warning: instance variable @eager_load_templates not initialized .../vendor/rails/actionpack/lib/action_view/paths.rb:48: warning: instance variable @eager_load_templates not initialized .../vendor/rails/actionpack/lib/action_view/paths.rb:48: warning: instance variable @eager_load_templates not initialized .../vendor/rails/actionpack/lib/action_view/paths.rb:48: warning: instance variable @eager_load_templates not initialized .../vendor/rails/actionpack/lib/action_view/paths.rb:48: warning: instance variable @eager_load_templates not initialized .../vendor/rails/actionpack/lib/action_view/paths.rb:48: warning: instance variable @eager_load_templates not initialized .../vendor/rails/actionpack/lib/action_view/paths.rb:48: warning: instance variable @eager_load_templates not initialized .../vendor/rails/actionpack/lib/action_view/paths.rb:48: warning: instance variable @eager_load_templates not initialized .../vendor/rails/actionpack/lib/action_view/paths.rb:48: warning: instance variable @eager_load_templates not initialized .../vendor/rails/actionpack/lib/action_view/paths.rb:48: warning: instance variable @eager_load_templates not initialized .../vendor/rails/actionpack/lib/action_view/paths.rb:48: warning: instance variable @eager_load_templates not initialized .../vendor/rails/actionpack/lib/action_view/paths.rb:48: warning: instance variable @eager_load_templates not initialized .../vendor/rails/actionpack/lib/action_view/paths.rb:48: warning: instance variable @eager_load_templates not initialized .../vendor/rails/actionpack/lib/action_view/paths.rb:48: warning: instance variable @eager_load_templates not initialized .../vendor/rails/actionpack/lib/action_view/paths.rb:48: warning: instance variable @eager_load_templates not initialized .../vendor/rails/actionpack/lib/action_view/paths.rb:48: warning: instance variable @eager_load_templates not initialized .../vendor/rails/actionpack/lib/action_view/paths.rb:48: warning: instance variable @eager_load_templates not initialized .../vendor/rails/activerecord/lib/active_record/connection_adapters/ abstract_adapter.rb:102: warning: instance variable @active not initialized .../lib/feed_interpreter.rb:38:in `parse’ …/app/models/feed.rb:59:in `fetch_feed' .../app/models/feed.rb:36:in `refresh’ That’s annoying.
