Hello! Sorry to bother you in your busy schedule. As a git beginner, I have a few simple questions to ask you First, how to implement the algorithm when there is file renaming in Git directory? By comparing the SHA1 value of the file, and then calling the GIT MV command? Second, how to implement the algorithm when there is file movement in Git directory? How is the tree object updated? Third, when a commit event occurs, the current blob file stores the full amount of data, while the previous version stores the incremental data But I didn't find out how to (local git database) when I actually used it. When git clone is used, the results are close to the conclusion These are not found in the book, so I have to bother you. I hope you can help me solve my confusion when you are free thank you very much indeed
