What is the best practice for maintaining a clean Git history when merging branches?
- Regularly force-push to keep the history linear and easy to follow.
- Merge frequently to avoid conflicts and maintain a linear history.
- Rebase branches before merging to create a clean, linear history.
- Always create a new branch for each feature and never merge branches.
Rebasing is a technique to maintain a clean and linear Git history by incorporating changes from one branch into another. It helps avoid unnecessary merge commits and keeps the commit history more readable and logical.
How does Git's branching model facilitate better integration with code quality tools compared to other VCS?
- Enables parallel development with feature branches, allowing isolated code quality checks.
- Discourages the use of branches, minimizing interference with code quality tools.
- Prioritizes a linear development workflow, hindering code quality integration.
- Only integrates with specific code quality tools, limiting flexibility.
Git Branching Model and Code Quality Integration
A new branch in Git can be created and switched to using the git _______ command.
- branch
- checkout
- merge
- commit
The 'git checkout' command is used to switch branches in Git. This command is also used to create a new branch and switch to it. The correct option is 'checkout'.
What are the implications of squashing commits when merging a feature branch into the main branch?
- Preserve individual commit history
- Combine multiple commits into one
- Increase repository size
- Create conflicts in the main branch
Squashing commits combines multiple commits into a single commit, providing a cleaner history. It helps maintain a more organized and readable history but can result in the loss of individual commit details.
The command git _______ is used to integrate changes from one branch to another.
- Checkout
- Merge
- Pull
- Push
The command git **merge** is used to integrate changes from one branch to another in Git. It combines changes from different branches.
A developer finds that some commits are missing from the Git history, suggesting a corrupted repository. What steps should they take to investigate and restore the repository?
- Use the git fsck command to check for object integrity and attempt to recover the missing commits.
- Clone a fresh copy of the repository from a backup.
- Delete the local repository and create a new one to start fresh.
- Run git blame on affected files to identify the missing commits and manually reapply them.
The git fsck command is used to check the integrity of objects in the Git database. Running this command can help identify and potentially recover missing commits. Restoring from a backup or recreating the repository may lead to data loss, making git fsck a more appropriate first step.
What is the role of Git hooks in securing a repository?
- Customizing pre-commit actions
- Implementing access control
- Enforcing coding standards
- Automating deployment
Git hooks are scripts that run automatically before or after events in Git. By implementing access control in hooks, you can secure the repository by controlling who can push changes and under what conditions.
To handle large codebases in enterprise environments, Git can be integrated with ________ for enhanced performance.
- Jenkins
- Docker
- Bitbucket
- GitLab
Git can be integrated with Docker for enhanced performance in handling large codebases. Docker provides containerization, allowing consistent environments across different stages of the development lifecycle. This integration aids in efficient deployment and scalability.
What command is used to start a new branch in Git?
- git branch
- git init
- git new-branch
- git checkout -b
The 'git checkout -b' command is used to create and switch to a new branch in one step. It is a convenient shortcut for creating feature branches.
git _______ is used to view the specific changes introduced in a commit.
- log
- show
- diff
- inspect
The correct option is "c) diff." The git diff command is used to show the changes between the working directory and the specified commit. It provides a line-by-line comparison of what was added, modified, or deleted.
