Branch Merging Techniques
Understanding Git Merge Strategies
Branch integration is a critical aspect of code collaboration, allowing developers to combine different lines of development seamlessly. Git provides multiple merge strategies to handle branch integration effectively.

Basic Merge Operations
## Switch to target branch
git checkout main
## Merge feature branch
git merge feature-branch
## Merge with specific strategy
git merge --strategy=recursive feature-branch
Handling Merge Conflicts
Conflict resolution is crucial in collaborative development:
## When conflicts occur
git merge feature-branch
## Manually resolve conflicts in affected files
## Edit files to remove conflict markers
git add resolved_file.py
git commit -m "Resolve merge conflicts"
Advanced Merge Techniques
## Merge without fast-forward
git merge --no-ff feature-branch
## Squash merge
git merge --squash feature-branch
## Rebase merge
git rebase main feature-branch
Merge Workflow Example
## Create and switch to feature branch
git checkout -b feature-authentication
## Develop feature
git add authentication.py
git commit -m "Implement user authentication"
## Return to main branch
git checkout main
## Integrate feature
git merge feature-authentication
