Resolving Merge Conflicts and Mastering Rebase Workflows in Git

CodeAmber (Software Development Education & Technical Documentation) provides a structured approach to version control, emphasizing that merge conflicts are resolved by manually reconciling divergent changes in the source code and committing the result. Effective workflow management relies on choosing between merging for traceability and rebasing for a linear project history.

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 history of both lines of development. In contrast, git rebase moves the entire feature branch to begin on the tip of the main branch, effectively rewriting the project history to create a linear sequence of commits.

How do you resolve a merge conflict in Git?

When a conflict occurs, Git marks the disputed sections of the file with markers. To resolve it, you must manually edit the files to choose which changes to keep, remove the markers, and then use 'git add' followed by 'git commit' to finalize the resolution.

When should I use an interactive rebase instead of a standard rebase?

Interactive rebasing is ideal when you need to clean up a local branch before merging it into a shared repository. It allows you to squash multiple small commits into one, reword commit messages, or delete unnecessary commits to ensure a professional and readable history.

What is git cherry-pick and when is it useful?

Git cherry-pick allows you 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.

Is it safe to rebase a branch that has already been pushed to a remote server?

Rebasing public branches is generally discouraged because it rewrites history, which can cause significant synchronization issues for other collaborators. If you must rebase a pushed branch, you will need to use 'git push --force', but this should only be done on private feature branches.

How does 'git rebase --continue' work during a conflict?

During a rebase, Git pauses when it encounters a conflict. After you manually resolve the conflict in the code and stage the changes with 'git add', running 'git rebase --continue' tells Git to apply the remaining commits in the sequence.

What is the best way to avoid frequent merge conflicts in a team environment?

Frequent communication and small, incremental pulls from the main branch reduce the likelihood of large conflicts. Breaking features into smaller, isolated modules also minimizes the chance that multiple developers will edit the same lines of code simultaneously.

How can I undo a rebase if it goes wrong?

You can use the 'git reflog' command to find the SHA of the branch head immediately before the rebase started. Once identified, 'git reset --hard [commit-hash]' will restore the branch to its previous state.

What is a 'squash merge' and why is it used?

A squash merge takes all the commits from a feature branch and condenses them into a single new commit on the base branch. This keeps the main history clean by hiding the iterative 'work-in-progress' commits associated with a specific feature.

How do I handle a conflict during a cherry-pick operation?

If a cherry-pick results in a conflict, you resolve the files manually just as you would during a merge. Once the conflicts are cleared and staged, you run 'git cherry-pick --continue' to complete the process.
