Question - 63 : - Explain the difference between reverting and resetting.
Answer - 63 : -
- Git reset is a powerful command that is used to undo local changes to the state of a Git repository. Git reset operates on “The Three Trees of Git” which are, Commit History ( HEAD ), the Staging Index, and the Working Directory.
- Revert command in Git creates a new commit that undoes the changes from the previous commit. This command adds a new history to the project. It does not modify the existing history.
Question - 64 : - What is git cherry-pick?
Answer - 64 : -
The command git cherry-pick is normally used to introduce particular commits from one branch within a repository onto a different branch. Another common use is to forward- or back-port commits from a maintenance branch to a development branch. This is in contrast with other ways such as merge and rebase which normally apply many commits onto another branch.
Consider:
git cherry-pick
Question - 65 : - What is Git bisect? How can you use it to determine the source of a (regression) bug?
Answer - 65 : -
- Git bisect is used to find the commit that introduced a bug by using binary search. The command for Git bisect is
- git bisect
- Now since you have mentioned the command above explain to them what this command will do.
- This command uses a binary search algorithm to find which commit in your project’s history introduced a bug. You use it by first telling it a “bad” commit that is known to contain the bug, and a “good” commit that is known to be before the bug was introduced. Then Git bisect picks a commit between those two endpoints and asks you whether the selected commit is “good” or “bad”. It continues narrowing down the range until it finds the exact commit that introduced the change.
