+title: Interactive Differential Debugging - Intelligent Auto-Stepping and Tab-Completion
+layout: gsoc_proposal
+project: CppInterOp
+year: 2025
+difficulty: medium
+duration: 350
+mentor_avail: June-October
+organization:

+
+## Description
+
+Differential debugging is a time-consuming task that is not well supported by existing tools. Existing state-of-the-art tools do not consider a baseline(working) version while debugging regressions in complex systems, often leading to manual efforts by developers to achieve an automatable task.
+
+The differential debugging technique analyzes a regressed system and identifies the cause of unexpected behaviors by comparing it to a previous version of the same system. The idd tool inspects two versions of the executable – a baseline and a regressed version. The interactive debugging session runs both executables side-by-side, allowing the users to inspect and compare various internal states.
+
+This project aims to implement intelligent stepping (debugging) and tab completions of commands. IDD should be able to execute until a stack frame or variable diverges between the two versions of the system, then drop to the debugger. This may be achieved by introducing new IDD-specific commands. IDD should be able to tab complete the underlying GDB/LLDB commands. The contributor is also expected to set up the necessary CI infrastructure to automate the testing process of IDD.
+
+## Expected Results
+
+* Enable stream capture
+* Enable IDD-specific commands to execute until diverging stack or variable value.
+* Enable tab completion of commands.
+* Set up CI infrastructure to automate testing IDD.
+* Present the work at the relevant meetings and conferences.
+
+## Requirements
+
+* Python & C/C++ programming
+* Familiarity debugging with GDB/LLDB
