The technique of _______ in Git allows the separation of large binary files from the codebase, ideal for database backups.
- cloning
- stashing
- LFS (Large File Storage)
- purging
The technique of LFS (Large File Storage) in Git allows the separation of large binary files from the codebase, making it ideal for managing database backups and other large assets. Git LFS replaces large files with text pointers, reducing the overall repository size and improving performance. This is particularly beneficial when dealing with large binary files commonly found in database backups.
In Git, what does the 'master' branch represent by default?
- The main development branch
- A branch for experimental changes
- A branch for emergency fixes
- A backup branch
By default, the 'master' branch in Git represents the main development branch. It is the default branch that is created when you initialize a new Git repository. Developers often use this branch for ongoing development and feature integration.
For complex project histories, the git ________ command is essential to filter and modify historical commits during migration.
- filter
- amend
- rebase
- cherry-pick
The rebase command is used to filter and modify historical commits during migration, allowing for a more organized and streamlined project history. This is crucial for complex project timelines.
How does cherry-picking affect the commit history in Git?
- It creates a new branch with the cherry-picked commit.
- It rewrites the commit history by applying the changes of the selected commit.
- It deletes the cherry-picked commit from the history.
- It merges the cherry-picked commit into the current branch.
Cherry-picking involves selecting a specific commit and applying its changes onto the current branch. It essentially rewrites the commit history, maintaining the selected changes without merging the entire branch. This can be useful for incorporating specific features or bug fixes from one branch to another without merging the entire commit history.
What is a common challenge when migrating from a centralized version control system to Git?
- Compatibility issues with existing repositories
- Lack of branching and merging capabilities
- Difficulty in learning Git commands
- Limited support for large codebases
When migrating from a centralized VCS to Git, compatibility issues with existing repositories often arise. Git's distributed nature may pose challenges in adapting to a different workflow, and ensuring a smooth migration is crucial.
After making several commits, a developer realizes they need to combine these commits into a single commit. What Git process should they follow?
- Use "git merge" to combine the commits
- Use "git squash" to merge the commits into a single commit
- Use "git combine" to merge the commits
- Use "git rebase" to combine the commits
The correct option is to use "git rebase" to combine the commits into a single commit. Rebase allows the developer to reapply commits on top of another base commit, effectively combining them into a single commit. Squash is used during interactive rebase to merge commits.
In a situation where multiple teams are working on different features simultaneously, how should merge conflicts be addressed to maintain a stable main branch?
- Prioritize conflicts based on team seniority
- Use feature branches and conduct regular merges to main
- Delay conflict resolution until the end of the project
- Create a separate unstable branch for each team
Using feature branches and regularly merging them into the main branch helps detect and resolve conflicts early. It ensures that the main branch remains stable, as conflicts are addressed incrementally. Options 1, 3, and 4 suggest approaches that are not recommended for maintaining a stable main branch in a collaborative environment.
What are the implications of using git rebase in a collaborative environment?
- It simplifies collaboration
- It makes collaboration complex
- It preserves the commit history
- It discards commit history
Git rebase rewrites commit history, which can lead to conflicts for collaborators who have already pulled the changes. It's important to use it carefully in a shared repository to avoid disrupting others' work.
How does the 'pre-receive' Git Hook differ from the 'post-receive' Hook?
- They both trigger before and after receiving data
- 'pre-receive' runs before updates are accepted, and 'post-receive' runs after updates are accepted
- 'pre-receive' runs after updates are accepted, and 'post-receive' runs before updates are accepted
- 'pre-receive' runs only for specific branches, 'post-receive' runs for all branches
The 'pre-receive' hook is invoked before any references are updated, allowing rejection of updates. In contrast, 'post-receive' is invoked after all refs have been updated, making it useful for triggering actions after the update. Understanding their timing is crucial for implementing custom Git workflows.
In a complex project workflow, a __________ Git hook can enforce commit message standards.
- Pre-commit
- Post-commit
- Pre-push
- Post-merge
In a complex project, a "Pre-commit" Git hook can be set up to enforce commit message standards before the actual commit is made. This ensures consistency in commit messages and helps maintain a clean commit history.
