RubyRunTracer__ is the module for tracing a line of data     #
in the output destination.                                   #
                                                             #            
The source of the trace can be data from forward-tracing     #
or data collected from a stack trace.			                  #

Instance Method Details

#back_trace_all(th_data_hash) ⇒ Object

The stack trace global hash is printed out in the rubyrun log in thread id order, also showing the top stack of all these threads before they were interrupted.

#enter_trace(tid, type, obj, invoker, klass, mid, *args) ⇒ Object

  1. If arguments are required to trace, try using kernel inspect to print it

  2. If obejct is required to trace, try using kernel inspect to print it.

Otherwise print class name, The inspect can cause recursion and blow up ruby. Rescue only delays the issue hence not used here.

  1. Show the last caller and line
