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.
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.
