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.
What is a common challenge when transitioning a legacy codebase to Git?
- Handling large files
- Maintaining commit history
- Limited branching and merging capabilities
- Lack of user interface
Transitioning a legacy codebase to Git can be challenging due to the need to maintain commit history, ensuring a smooth transition without losing valuable information about the codebase's evolution.
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'.
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.
How do you update a Git Submodule to the latest commit in its repository?
- git submodule update --remote
- git submodule sync
- git submodule fetch
- git submodule pull
To update a Git Submodule to the latest commit in its repository, you use the command git submodule update --remote. This command fetches the latest changes from the submodule's repository and updates the working directory to the new commit.
In DevOps practices, how is Git typically used for source code management?
- Version Control
- Continuous Integration
- Continuous Deployment
- All of the Above
Git is primarily used as a Version Control System in DevOps practices to track changes, collaborate, and maintain a history of codebase modifications.
What is the primary purpose of a version control system?
- A version control system is used for code collaboration.
- A version control system is used for debugging code.
- A version control system is used for file backup.
- A version control system is used for tracking changes in code.
The primary purpose of a version control system, like Git, is to track changes in code and manage different versions of files. It allows developers to collaborate, review changes, and revert to previous versions if needed.
Your team decides to enforce a linear history on the main branch. Which Git feature would be most appropriate to achieve this?
- merge
- rebase
- squash
- cherry-pick
The correct option is rebase. Rebasing helps create a linear history by incorporating changes from one branch onto another, eliminating unnecessary merge commits. This promotes a cleaner and more straightforward history, especially on the main branch.
