Module: DiverDown::Trace::RedefineRubyMethods

Defined in:
lib/diver_down/trace/redefine_ruby_methods.rb

Overview

Tracepoint traces only ruby-lang calls because tracing c-lang calls is very slow. In this case, methods such as new will not be traceable under normal circumstances, so at a minimum, redefine them in ruby and hack them so that they can be traced.

Do not use this in a production environment.
