Git concepts: bisecting

Rebasing in Git is a method for integrating changes from one branch to another. It's similar to merging, but instead of incorporating all the new commits from one branch into another via a merge commit, rebasing re-writes the commit history by creating new commits for each existing commit in the original branch.

Here's a basic workflow of how rebasing works:

You start with a base branch (often 'master' or 'main') and a feature branch that you want to base onto the base branch.

You checkout to your feature branch and execute the command 'git rebase master'.

Git finds the common ancestor of the two branches, takes the diff introduced by each commit of the feature branch, and re-applies them on the base branch.

One major benefit of rebasing is that it can make your feature branch up to date with the latest code from the base branch without polluting your Git history with unnecessary merge commits. This results in a cleaner, linear project history.

However, rebasing isn't always the right choice. Since it rewrites the commit history, it can be dangerous if you're collaborating with others on a branch. It's generally a good practice to only rebase your local branches that haven't been pushed to the remote repository.

In case conflicts arise during rebasing, Git will pause and allow you to resolve those conflicts before continuing. After resolution, you can continue the rebase with 'git rebase --continue'.

In summary, rebasing is a Git technique that allows you to integrate changes from one branch into another by creating new commits for each existing commit in the original branch. It helps to maintain a clean, linear project history.
