What is a Git alias?
- A shortcut for a Git command
- A unique identifier for a Git repository
- A branch in a Git repository
- A tool for creating Git repositories
A Git alias is a custom shortcut for a Git command. It allows users to create their own shorthand notation for frequently used Git commands, making the command-line interface more efficient and user-friendly. For example, you can create an alias 'co' for 'checkout' to save typing time.
A DevOps pipeline often uses git _______ to trigger automated builds and tests.
- COMMIT
- PUSH
- HOOKS
- TAG
Git hooks are scripts that can be triggered at different points in the Git workflow. The post-receive hook, in particular, is commonly used in DevOps pipelines to initiate automated processes like builds and tests after receiving new code.
What are the implications of detaching a Git Submodule?
- No impact
- Submodule becomes independent of the parent repository
- Changes in the submodule are reflected in the parent
- Submodule is deleted from the parent repository
Detaching a Git Submodule means it becomes independent, allowing changes without affecting the parent repository. However, it also implies that the submodule is no longer tied to a specific commit, making it susceptible to unintended changes. Managing submodule detachment is crucial for version consistency.
Open source projects typically use git _______ to manage and review contributions from various developers.
- CLONE
- BRANCH
- FORK
- MERGE
In open source development, developers typically fork a repository to create their copy, make changes, and then submit pull requests. This process allows project maintainers to review and merge contributions systematically.
What is the difference in handling merge requests in GitLab versus pull requests in GitHub?
- Terminology
- Functionality
- Repository hosting
- Collaboration features
While both GitLab and GitHub facilitate code collaboration, understanding the terminology and functionality differences in handling merge requests (GitLab) and pull requests (GitHub) is essential. GitLab uses the term "merge request" while GitHub uses "pull request," and there are nuanced differences in how they handle code reviews, approvals, and merging changes into the main branch.
How can you cherry-pick a commit from another branch into your current branch in Git?
- git pick -c
- git cherry-pick
- git apply
- git merge
The correct option is git cherry-pick . This command allows you to apply the changes introduced by the specified commit to your current branch. Cherry-picking is useful for selectively bringing in specific changes.
A team is facing an issue where a feature that previously worked is now broken. How can git bisect be used to identify the problematic commit?
- Start the bisect using git bisect start and specify a good and bad commit. Git will automatically check out a commit between them. Run tests, and based on results, mark the commit as good or bad using git bisect good or git bisect bad.
- Manually check out a commit, run tests, and mark the commit as good or bad using git bisect mark.
- Use git bisect log to view the history and identify the problematic commit manually.
- Execute git bisect run
to automate the testing process and identify the faulty commit.
Option 1 correctly describes the process of using git bisect to systematically find the commit introducing the issue by marking commits as good or bad based on test results. Other options either involve manual methods or incorrect usage of git bisect.
How can you protect sensitive data from being committed in Git?
- Use environment variables
- Encrypt the entire repository
- Add sensitive files to the .gitignore
- Use the git secure command
To protect sensitive data from being committed, you should add the sensitive files or patterns to the .gitignore file. This ensures that Git ignores these files, preventing them from being included in the version control system and shared with others.
How does the 'shallow clone' feature in Git help with large repositories?
- A shallow clone reduces the repository's size by fetching only the latest commit history.
- Shallow clones improve network efficiency by fetching less data during cloning.
- Shallow clones allow for faster cloning of repositories by skipping unnecessary history.
- Shallow clones only fetch the latest commit, excluding any historical data.
The 'shallow clone' feature in Git allows users to clone a repository with a limited history, reducing the time and bandwidth required for cloning. Shallow clones are useful when dealing with large repositories where fetching the entire history may be unnecessary.
To maintain a clean project history, the ________ strategy can be used to combine a series of commits into a single cohesive commit.
- Squash
- Rebase
- Amend
- Reset
To maintain a clean project history, the rebase strategy can be used to combine a series of commits into a single cohesive commit. Rebasing involves moving, combining, or modifying commits to create a linear and more readable project history. This helps in presenting a cleaner and more organized timeline of changes, making it easier to understand the development history and trace back specific features or bug fixes.
