In migrating a large codebase to Git, what factors influence the choice of using a monorepo versus multiple smaller repositories?
- Easier management of dependencies in a monorepo compared to smaller repositories.
- Facilitates better code isolation and release management in smaller repositories.
- Monorepo is always preferred for large codebases, irrespective of other factors.
- Multiple smaller repositories lead to improved build and deployment processes.
Choosing Between Monorepo and Multiple Repositories in Git
What are the challenges of using Git in conjunction with build automation tools?
- Managing dependencies and ensuring consistent builds.
- Difficulty in integrating Git with Continuous Integration (CI) systems.
- Limited support for parallel builds.
- Inability to version control build artifacts.
Challenges of using Git with build automation tools include managing dependencies and ensuring consistent builds. Versioning build artifacts and integrating with CI systems can also pose difficulties.
How does splitting a large repository into smaller ones affect Git performance?
- Improved performance
- No impact on performance
- Reduced performance
- Performance varies based on file types
Splitting a large repository into smaller ones can improve Git performance. Smaller repositories result in faster cloning, fetching, and overall better performance, as Git operations are more streamlined with reduced data to handle.
In terms of secure Git practices, what is the significance of signed commits?
- It speeds up commit operations
- It encrypts the commit messages
- It ensures the integrity and authenticity of commits
- It restricts commit access
Signed commits ensure the integrity and authenticity of commits by associating them with a GPG key. This helps verify that the commits come from a trusted source and haven't been tampered with.
In a code review, what should be the primary focus when evaluating a pull request?
- Syntax and coding style, Functional correctness, Performance optimization, Documentation
- Ignore syntax errors, Focus only on coding style, Prioritize performance over functionality, Neglect documentation
- Ignore functional correctness, Ignore performance issues, Focus only on documentation, Prioritize syntax over coding style
- Prioritize documentation over functionality, Focus only on syntax, Ignore performance and coding style, Neglect functional correctness
The primary focus in a code review should be on functional correctness. Ensuring that the code behaves as intended is crucial. While other aspects like coding style, performance, and documentation are important, they are secondary to the core functionality of the code.
How do pull requests in platforms like GitHub and GitLab facilitate code collaboration?
- Enable developers to propose changes, discuss modifications, and ensure seamless integration of new code.
- Manage access controls and user permissions for repositories.
- Automatically merge all changes without any review.
- Only available in GitLab, not GitHub.
Pull requests in platforms like GitHub and GitLab serve as a collaborative mechanism for proposing changes. Developers can discuss modifications, ensuring seamless integration of new code into the main branch.
For high performance in large-scale Git operations, setting the git __________ configuration can significantly reduce latency.
- git config --optimize
- git config --pack
- git config --large
- git config --delta
Setting the pack configuration in Git (git config --pack) helps in optimizing storage and improving performance by packing objects efficiently. This is especially beneficial for large-scale Git operations.
For an open source project on GitHub, what is the standard method for contributing changes?
- Cloning the repository and directly making changes
- Sending an email with code changes
- Creating a new repository
- Forking the repository and submitting a pull request
The standard method for contributing to an open source project on GitHub is to fork the repository, create a new branch, make changes, and then submit a pull request to the original repository.
In what way does integrating Git with an IDE assist in resolving merge conflicts?
- Visual Conflict Resolution
- Automated Conflict Resolution
- Conflict Ignoring
- Merge Conflict Alerts
Integrating Git with an Integrated Development Environment (IDE) provides visual tools for conflict resolution. Developers can easily view and resolve conflicts, making the process more intuitive and efficient.
What Git command would you use to discard changes in a specific file before it has been staged?
- git checkout -- filename
- git reset HEAD filename
- git restore filename
- git revert filename
The correct option, git checkout -- filename, discards changes in a specific file before staging. It reverts the file to the last committed state. git reset HEAD filename unstages changes, git restore filename is used after staging, and git revert filename is for creating a new commit to undo changes.
A team is transitioning a large legacy codebase to Git. They encounter issues with large binary files. What Git feature should they consider using?
- Git LFS
- Git submodules
- Git cherry-pick
- Git rebase
Large binary files can be efficiently managed using Git LFS (Large File Storage). Git LFS is an extension that replaces large files in a repository with tiny pointer files while storing the actual file contents on a separate server. This helps in handling binary files more effectively.
A company is transitioning from SVN to Git. They want to ensure their historical branches and tags are preserved. What migration strategy should they use?
- Fast-Forward Merge
- Rebase
- Submodule
- git-svn
The git-svn option allows for a smooth transition from SVN to Git, preserving historical branches and tags. It maintains compatibility during migration.
