During migration to Git, what is the best strategy to preserve the commit history from the previous version control system?
- Create a mapping between old and new commits, ensuring each commit is accounted for.
- Discard the old commit history for simplicity.
- Convert all old commits into a single initial commit in Git.
- Use a third-party tool to import commits directly.
When migrating to Git, it's crucial to establish a mapping between old and new commits to preserve the commit history accurately. Discarding history or converting all commits into one may result in loss of valuable information. Using third-party tools can help in importing commits seamlessly.
What Git feature is particularly useful for managing different releases in open source projects?
- Git Branching
- Git Forking
- Git Merging
- Git Cloning
Git branching is particularly useful for managing different releases in open source projects. Each branch can represent a different version or release, allowing for parallel development and easy maintenance of multiple code bases.
The git _______ command is used to change a commit message that hasn't been pushed yet.
- commit --amend
- commit --modify
- commit --edit
- commit --change
The correct option is commit --amend. This command allows you to modify the last commit's message. It's useful when you need to make small changes or corrections to the commit message before pushing it to the remote repository.
When setting up a new remote repository, the command git remote add origin _______ is used.
- https://github.com/user/repo.git
- origin
- master
- git remote
The correct option is a. https://github.com/user/repo.git. This option represents the URL of the remote repository, and 'origin' is a common name given to the remote. While 'origin' is used in the command, it is not a placeholder for the repository URL. It's important to correctly specify the remote repository's URL when adding a remote to your local repository to establish a connection for pushing and pulling changes.
What is a common use of git stash in Git?
- Discarding changes
- Storing changes temporarily
- Applying changes to the remote repository
- Deleting the entire repository
Git stash is commonly used to temporarily store changes that are not ready to be committed. This is useful when you need to switch to a different branch or address an urgent issue, allowing you to save your work without committing it.
To see a graphical representation of the commit history, you can use git log --_______.
- graph
- oneline
- pretty
- graphoneline
The correct option is git log --graph. This option provides a graphical representation of the commit history, showing branches and merges.
What is the impact of having a large number of branches in a Git repository on its performance?
- A large number of branches has no impact on Git repository performance.
- More branches lead to faster Git operations due to parallel processing.
- Having many branches can slow down Git operations like cloning and fetching.
- Git performance is not affected by the number of branches in a repository.
Having a large number of branches in a Git repository can negatively impact performance, especially during operations like cloning and fetching. Each branch adds overhead, and repositories with excessive branches may experience slower operations.
In a project with multiple contributors, two developers have made different changes to the same file. What Git feature will help resolve this when merging?
- Cherry-pick
- Merge Conflict Resolution
- Stash
- Bisect
When there are conflicting changes in the same file, Git's merge conflict resolution feature helps developers manually resolve conflicts and merge the changes successfully.
The git ________ command can be particularly useful in IDEs for exploring code history.
- log
- status
- diff
- commit
The "git log" command displays the commit history of the repository. In an IDE, this can be useful for developers to understand the chronological order of changes, who made them, and the associated commit messages. It aids in exploring the code history and tracking changes over time.
A developer wants to temporarily save changes without committing them to maintain a clean project history. What Git feature should they use?
- git stash
- git branch
- git commit --amend
- git tag
The correct option is a. git stash. This command allows the developer to save changes without committing them and revert the working directory to the last commit. It's useful for switching to a different branch or applying changes later. git branch is used to create, list, or delete branches. git commit --amend is used to modify the last commit, and git tag is used to create tags.
