What is the primary difference between git merge and git rebase?
Git merge combines two branches by creating a new 'merge commit' that preserves the complete chronological history of both lines of development. Git rebase moves the entire feature branch to begin on the tip of the main branch, effectively rewriting project history to create a linear sequence of commits.
How should developers handle merge conflicts efficiently?
Merge conflicts occur when Git cannot automatically reconcile differences between two commits. To resolve them, developers should identify the conflicting files, manually select the desired code changes in a text editor or IDE, stage the resolved files using 'git add', and complete the process with a final commit.
What is the Gitflow workflow and when should it be used?
Gitflow is a strict branching model that utilizes dedicated branches for features, releases, and hotfixes, orbiting a permanent 'develop' and 'main' branch. It is best suited for projects with scheduled release cycles and a need for rigorous quality assurance before code reaches production.
What are the best practices for writing commit messages?
Effective commit messages should start with a concise summary line in the imperative mood, such as 'Fix bug in authentication logic' rather than 'Fixed bug'. For complex changes, a blank line should separate the summary from a detailed body explaining the 'why' behind the change.
When is it appropriate to use git stash?
Git stash is used when a developer needs to switch contexts or branches quickly without committing incomplete or unstable work. It temporarily shelves current changes in a local stack, allowing the working directory to be cleaned before the changes are later reapplied using 'git stash pop'.
What is the difference between a soft reset and a hard reset in Git?
A soft reset moves the HEAD pointer back to a previous commit but keeps all changes staged in the index. A hard reset moves the HEAD pointer and wipes all changes from both the index and the working directory, permanently deleting uncommitted work.
How does git cherry-pick work and when is it useful?
Git cherry-pick allows a developer to apply a specific commit from one branch onto another without merging the entire branch. This is particularly useful for porting a critical bug fix from a development branch directly into a production release branch.
What is the purpose of a .gitignore file?
A .gitignore file tells Git which files or directories to ignore and exclude from version tracking. This is essential for preventing sensitive data, such as API keys, or environment-specific files, like node_modules or .DS_Store, from being committed to the repository.
What is the advantage of using feature branches over working directly on the main branch?
Feature branches isolate new development from the stable production code, allowing multiple developers to work on different tasks simultaneously without introducing instability. This workflow enables the use of Pull Requests for peer review and automated testing before integration.
How can developers recover a lost commit after a hard reset?
Lost commits can often be recovered using the 'git reflog' command, which records every movement of the HEAD pointer. By identifying the SHA-1 hash of the commit prior to the reset, a developer can restore the state using 'git reset --hard [hash]'.
