What is the fundamental difference between git merge and git rebase?
Git merge combines two branches by creating a new 'merge commit' that preserves the chronological history of both lines of development. In contrast, git rebase rewrites the project history by moving the entire current branch to begin on the tip of the target branch, resulting in a linear sequence of commits.
When should a developer choose rebase over merge?
Rebasing is ideal for cleaning up local feature branches before integrating them into a shared main branch to avoid unnecessary merge commits. However, it should never be used on public or shared branches, as rewriting history can disrupt other collaborators' local repositories.
How do you resolve a complex merge conflict in Git?
Resolve conflicts by identifying the markers (<<<<<<<, =======, >>>>>>>) in the affected files and manually selecting the desired code. Once the conflicts are resolved, you must stage the files using 'git add' and complete the process with 'git commit' to finalize the integration.
What is a 'detached HEAD' state and how do you fix it?
A detached HEAD occurs when you check out a specific commit or tag rather than a branch, meaning any new commits will not belong to any branch. To fix this, you can either return to a named branch using 'git checkout [branch-name]' or save your work by creating a new branch from the current state.
What is the purpose of git stash and when should it be used?
Git stash temporarily shelves uncommitted changes (both staged and unstaged) to clean the working directory without losing progress. This is most useful when you need to switch branches urgently to fix a bug but are not yet ready to commit your current work.
How does git cherry-pick function in a professional workflow?
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 directly into a production release branch.
What is the difference between a soft reset and a hard reset?
A soft reset ('--soft') moves the HEAD pointer back to a previous commit but keeps your changes staged in the index. A hard reset ('--hard') wipes the working directory and the index entirely, reverting the project to the exact state of the specified commit.
How can you recover a deleted commit or lost work in Git?
Most lost commits can be recovered using 'git reflog', which records every time the HEAD of a branch is updated. By finding the SHA-1 hash of the lost commit in the reflog, you can restore it using 'git checkout' or 'git merge'.
What are the best practices for writing commit messages?
Professional commit messages should feature a short, imperative summary line (e.g., 'Fix memory leak in API') followed by a blank line and a detailed body explaining the 'why' behind the change. This ensures the project history remains searchable and understandable for other engineers.
What is the role of a .gitignore file in a software project?
A .gitignore file tells Git which files or directories to ignore and never track, such as build artifacts, local environment variables, and dependency folders like node_modules. This prevents sensitive data and redundant files from bloating the remote repository.
