What is a common benefit observed when implementing Git in large projects?
- Enhanced collaboration among team members
- Improved version control and code history
- Better support for Agile development
- Increased code stability
Git in Large Projects
A developer needs to integrate their feature branch with the latest updates from the main branch, but wants to maintain a clean history. Should they use merge or rebase, and why?
- Merge
- Rebase
- Merge and then Rebase
- Rebase and then Merge
When integrating a feature branch with the main branch while maintaining a clean history, rebase is preferred over merge. Rebase allows for a linear and cleaner commit history by applying the feature branch's changes on top of the main branch, avoiding unnecessary merge commits. This promotes a more straightforward and readable history.
To revert to a particular commit, the command git revert ______ is used.
- commit
- revert
- reset
- restore
The correct option is "revert." When you want to revert to a particular commit in Git, you use the git revert command followed by the commit hash. This creates a new commit that undoes the changes introduced by the specified commit.
How do you check the current version of Git installed on your system?
- git version
- git show
- git status
- git check
To check the current version of Git, you can use the git version command. This will display the installed Git version on your system. The other options are not suitable for checking the Git version.
How does the Forking workflow model differ from the Feature Branch workflow?
- Both workflows involve separate branches, but in Forking, contributors clone the repository independently, while in Feature Branch, contributors create branches within the main repository.
- Forking creates a separate copy of the entire repository for each contributor, whereas Feature Branch allows contributors to work in their branches within the main repository.
- Forking requires merging pull requests to the upstream repository, while Feature Branch involves merging directly into the main branch.
- Feature Branch workflow allows more flexibility for individual contributors, while Forking workflow is more centralized.
The Forking model involves contributors creating a copy (fork) of the repository, making changes, and then issuing pull requests to merge changes back. Feature Branch involves creating branches within the main repository for each feature or bug fix.
What is the main purpose of using Git Submodules?
- Code sharing between repositories
- Version control for individual files
- Merging branches
- Creating lightweight branches
Git Submodules are used for integrating external repositories as a subdirectory within a main repository. The main purpose is code sharing between repositories, allowing you to include external projects while keeping them isolated.
The git ________ command provides a byte-wise comparison between two branches to diagnose corruption or discrepancies.
- git diff
- git compare
- git diagnose
- git verify
The correct option is git diff. This command is used to show the differences between two branches at a byte level, making it useful for diagnosing corruption or discrepancies in the branches.
What is a pull request in the context of Git?
- A way to request someone to pull your changes
- A command to pull the latest changes from the remote repository
- A request to merge two branches
- A request to undo the last commit
A pull request is a method used to propose changes to a repository. It allows collaborators to review and discuss the changes before merging them into the main branch. It typically includes details about the changes made and the reason for the changes. This is an essential part of the collaborative workflow in Git.
What is the purpose of the .gitignore file in a Git repository?
- Exclude specific files from version control
- Store sensitive data
- Track changes in the repository
- Create backups automatically
The .gitignore file is used to exclude specific files or patterns from being tracked by Git. This is helpful to avoid cluttering the repository with files that shouldn't be versioned, such as temporary files, build artifacts, or system-specific files.
When stashing changes, what happens to the staged and unstaged modifications in Git?
- Staged changes are preserved, unstaged changes are discarded
- Both staged and unstaged changes are preserved
- Staged changes are discarded, unstaged changes are preserved
- Both staged and unstaged changes are discarded
When you stash changes, Git saves both staged and unstaged changes. This allows you to switch branches without committing changes, and later apply the stash to continue working on the changes.
