What is the fundamental difference between GitFlow and Trunk-based development?
GitFlow utilizes a strict branching model with dedicated branches for features, releases, and hotfixes, making it ideal for scheduled release cycles. Trunk-based development requires developers to merge small, frequent updates into a single core branch, prioritizing continuous integration and faster deployment cycles.
How should a team resolve a merge conflict in Git?
To resolve a merge conflict, a developer must manually open the affected files, identify the conflicting code blocks marked by Git, and choose which changes to keep. Once the conflicts are manually reconciled, the developer stages the resolved files and completes the merge with a commit.
When should a developer use 'git rebase' instead of 'git merge'?
Git rebase is preferred when a developer wants to maintain a linear project history by moving their local commits to the tip of the main branch. In contrast, git merge preserves the complete chronological history and the context of when a feature branch was joined back into the main line.
What is the purpose of a .gitignore file in a collaborative project?
A .gitignore file tells Git which files or directories to ignore and exclude from version tracking. This prevents sensitive information, such as API keys, and environment-specific files, like node_modules or build artifacts, from being committed to the shared repository.
How does 'git stash' help in a multi-tasking development environment?
Git stash allows a developer to temporarily shelve uncommitted changes to a clean working directory without creating a formal commit. This is useful when a developer needs to switch branches quickly to address a high-priority bug without losing their current progress.
What is the difference between a 'git fetch' and a 'git pull'?
Git fetch downloads the latest metadata and commits from a remote repository but does not integrate them into the local working files. Git pull performs a git fetch and immediately follows it with a git merge, updating the local branch to match the remote state.
What are the best practices for writing a commit message in a professional team?
Professional commit messages should use the imperative mood (e.g., 'Fix bug' instead of 'Fixed bug') and provide a concise summary in the first line. If the change is complex, a blank line should separate the summary from a detailed body explaining the 'why' behind the change.
How can a team recover a deleted commit or a lost branch?
Teams can use the 'git reflog' command to view a history of all recent movements of the HEAD pointer, including commits that are no longer reachable by any branch. Once the commit hash is identified from the reflog, the developer can use 'git checkout' or 'git merge' to restore the lost state.
What is a 'cherry-pick' in Git and when is it used?
Git cherry-pick allows a developer to apply a specific commit from one branch onto another without merging the entire branch. This is typically used to port a critical bug fix from a development branch into a production release branch without including unfinished features.
What is the role of a Pull Request (PR) in the version control workflow?
A Pull Request is a mechanism for developers to notify team members that a feature is complete and ready for review. It provides a forum for code review, automated testing, and discussion before the changes are formally merged into the main codebase.
