Overview of this book

Git is one of the most popular types of Source Code Management (SCM) and Distributed Version Control System (DVCS). Despite the powerful and versatile nature of the tool enveloping strong support for nonlinear development and the ability to handle large projects efficiently, it is a complex tool and often regarded as “user-unfriendly”. Getting to know the ideas and concepts behind the architecture of Git will help you make full use of its power and understand its behavior. Learning the best practices and recommended workflows should help you to avoid problems and ensure trouble-free development. The book scope is meticulously designed to help you gain deeper insights into Git's architecture, its underlying concepts, behavior, and best practices. Mastering Git starts with a quick implementation example of using Git for a collaborative development of a sample project to establish the foundation knowledge of Git operational tasks and concepts. Furthermore, as you progress through the book, the tutorials provide detailed descriptions of various areas of usage: from archaeology, through managing your own work, to working with other developers. This book also helps augment your understanding to examine and explore project history, create and manage your contributions, set up repositories and branches for collaboration in centralized and distributed version control, integrate work from other developers, customize and extend Git, and recover from repository errors. By exploring advanced Git practices, you will attain a deeper understanding of Git’s behavior, allowing you to customize and extend existing recipes and write your own.

Chapter 7. Merging Changes Together

The previous chapter, Advanced Branching Techniques, described how to use branches effectively for collaboration and development.

This chapter will teach you how to integrate changes from different parallel lines of development (that is, branches) together by creating a merge commit, or by reapplying changes with the rebase operation. Here, the concepts of merge and rebase are explained, including the differences between them and how they both can be used. This chapter will also explain the different types of merge conflicts, and teach how to examine them, and how to resolve them.

In this chapter, we will cover the following topics:

  • Merging, merge strategies, and merge drivers

  • Cherry-picking and reverting a commit

  • Applying a patch and a patch series

  • Rebasing a branch and replaying its commits

  • Merge algorithm on file and contents level

  • Three stages in the index

  • Merge conflicts, how to examine them, and how to resolve them

  • Reusing recorded [conflict] resolutions with...
