How can Git be integrated with automated build systems?
- By configuring build scripts to pull code from Git repositories
- By manually copying files from Git to the build server
- By disabling version control during the build process
- By relying solely on manual code deployment
Git can be integrated into automated build systems by configuring build scripts to pull the latest code from Git repositories, ensuring an automated and streamlined build process.
The command git _______ is used to view the commit history graphically, showing branches and merges.
- log
- history
- show
- graph
The command git log is used to view the commit history, but for a graphical representation showing branches and merges, the git log --graph command is used. This option helps visualize the branching and merging structure of the repository.
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 Git store data?
- Git stores data in a centralized database.
- Git stores data in a distributed manner.
- Git stores data in a local cache.
- Git stores data in a relational database.
Git stores data in a distributed manner. Each user's local repository contains the entire history and data, making it highly efficient and capable of functioning independently even without a network connection.
When a merge conflict occurs, which section of the conflict markers indicates the changes from the current branch?
- <<<<<<< HEAD
- =======
- >>>>>>> branch-name
- <<<<<<< branch-name
The section <<<<<<< HEAD indicates the changes from the current branch in a merge conflict. Developers should edit the content between this marker and ======= to resolve conflicts manually.
