Temporal Debugging using URDB

Understand

A new style of temporal debugging is proposed.

• The new URDB debugger can employ such techniques as temporal search for finding an underlying fault that is causing a bug.
• This improves on the standard iterative debugging style, which iteratively re-executes a program under debugger control in the search for the underlying fault.
• URDB acts as a meta-debugger, with current support for four widely used debuggers: gdb, MATLAB, python, and perl.
