Resolved target branch behind current branch

To resolve the situation where the source branch is behind the target branch and you need to merge changes into the master branch, follow these steps. This guide assumes you are using Git as your version control system:

1. Update Your Local Repository: First, ensure your local repository is up-to-date with the remote repository.

   git fetch origin

2. Checkout the Source Branch: Switch to the source branch that you are working on.

   git checkout source-branch

3. Rebase or Merge the Target Branch: Since the source branch is 30 commits behind the target branch, you need to either rebase or merge the target branch into your source branch. This will help in resolving any conflicts before merging into master.

   • Rebase (preferred if you want a cleaner history):

     git rebase origin/target-branch

     Resolve any conflicts that arise. After resolving conflicts, continue the rebase:

     git rebase --continue

     Repeat until the rebase is complete. You can test and review the branch:

   git log --oneline
   git status
   git push origin qa --force

   • Merge:

     git merge origin/target-branch

     Resolve any conflicts, then commit the merge:

     git commit -am "Merge target-branch into source-branch"

4. Test Your Changes: After merging or rebasing, thoroughly test your changes to ensure that the integration of the new commits from the target branch hasn’t broken any functionality.

5. Push Changes to Remote Source Branch (if needed): If others are using the same source branch or you need to preserve the changes on the remote repository, push your changes:

   git push origin source-branch

6. Merge into Master: Once your source branch is updated and tested, you can merge it into the master branch. Since you mentioned squashing the commits, you can use the following commands:

   git checkout master
   git merge --squash source-branch
   git commit -m "Your commit message"

   This will squash all the changes into a single commit.

7. Push Master to Remote: Finally, push the changes to the master branch on the remote repository:

   git push origin master

By following these steps, you ensure that your source branch is up-to-date with the target branch, and you cleanly integrate the changes into the master branch with a squash merge.
