In order to deliver debug information to dev team
instead of display error message to end user
Implemented strict validation concept
that suppose to define validation that always raise exception when fails

fix misleading comment (originally made by Tate Johnson, we lost this commit while porting to the rails repo)

This breaks #6448, you should use :"module/class" as key for namespacing

This is required because the JSON gem is incompatible with Rails behavior and was not allowing ActiveModel::Errors to be serialized.
So we need to ensure Rails implementation is the one triggered. [#4890 state:resolved]

Regression with how base errors messages are added to a model. Works correctly for both string error messages and symbol translated messages.

Make ActiveModel::Errors#add_on_blank and #add_on_empty accept an options hash and make various Validators pass their (filtered) options.

This makes it possible to pass additional options through Validators to message generation. E.g. plugin authors want to add validates_presence_of :foo, :format => "some format".

Also, cleanup the :default vs :message options confusion in ActiveModel validation message generation.

Also, deprecate ActiveModel::Errors#add_on_blank(attributes, custom_message) in favor of ActiveModel::Errors#add_on_blank(attributes, options).

Also, refactoring of ActiveModel and ActiveRecord Validation tests. Test are a lot more DRY now. Better test coverage as well now.

The first four points were reapplied from an older patch of Sven Fuchs which didn't apply cleanly anymore and was not complete yet.
