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 complete chronological history of both paths. Git rebase instead moves the entire feature branch to begin on the tip of the main branch, effectively rewriting history to create a linear sequence of commits.
When should a developer choose git rebase over git merge?
Rebasing is ideal for cleaning up local feature branches before they are merged into a shared main branch, as it eliminates unnecessary merge commits. This results in a cleaner, linear project history that is easier to navigate during audits or debugging.
What is the primary risk associated with using git rebase on public branches?
Because rebasing rewrites commit hashes, using it on a public or shared branch can confuse other collaborators and cause significant synchronization issues. This often leads to duplicate commits and complex conflicts that require manual intervention to resolve.
How does git cherry-pick work in a professional workflow?
Git cherry-pick allows a developer to select a specific commit from one branch and apply it to another without merging the entire branch. This is particularly useful for porting critical bug fixes from a development branch directly into a production release.
What is the best strategy for resolving complex merge conflicts?
The most effective approach is to resolve conflicts incrementally by merging the target branch into the feature branch frequently. Using a dedicated merge tool or an IDE with a three-way merge view helps developers visualize the base, local, and remote changes to make informed decisions.
What is an interactive rebase and how is it used for clean code?
An interactive rebase allows developers to modify their commit history by squashing multiple small commits into one, renaming commit messages, or deleting unnecessary changes. This process ensures that the final pull request is concise and logically structured for reviewers.
How do you recover a lost commit after a failed rebase or reset?
Developers can use the 'git reflog' command to view a history of all movements of the HEAD pointer. By identifying the commit hash prior to the error, the developer can use 'git reset --hard' to restore the branch to its previous state.
What is the purpose of a 'squash merge' in a CI/CD pipeline?
A squash merge condenses all commits from a feature branch into a single commit on the main branch. This keeps the main history streamlined and prevents the production log from being cluttered with minor 'work-in-progress' commits.
How does git stash assist in managing context switching?
Git stash temporarily shelves uncommitted changes in a local stack, allowing a developer to switch branches without committing incomplete work. Once the urgent task is finished, the developer can apply the stashed changes back to their original branch.
What is the difference between a fast-forward merge and a three-way merge?
A fast-forward merge occurs when the target branch has no new commits since the feature branch diverged, allowing Git to simply move the pointer forward. A three-way merge is required when both branches have diverged, necessitating a new merge commit to tie the histories together.
