• Student Name: Vikram Atreyapurapu
• GSoC Project: Implementing UNDO

   The project started with deciding which kind of undo to be implemented. Various implementations were thought about including a complete re-run approach, partial checkpoint, full checkpoint, etc as discussed in detail in my [[1]]. Using a version control system like libgit2 was also explored, but was found to be sub-optimal since it was occupying a lot of extra space and was also not very time efficient. 
   It was decided that the undo would be implemented using a partial checkpoint-like approach, where a change in an object at any step would be the only thing stored at that step instead of storing a full checkpoint of the .g file at that point.
