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.

Data recovery and troubleshooting


It is almost impossible to never make any mistakes. This applies also to using Git. The knowledge presented in this book, and your experience with using Git, should help in reducing the number of mistakes. Note that, Git tries quite hard not to make you lose your work; many mistakes are recoverable.

Recovering a lost commit

It may happen that you accidentally lost a commit. Perhaps, you force-deleted an incorrect branch that you were to be working on, or you rewound the branch to an incorrect place, or you were on an incorrect branch while starting an operation. Assuming something like this happened, is there any way to get your commits back and to undo the mistake?

Because Git does not delete objects immediately, but keeps them for a while, and only deletes them if they are unreachable during the garbage collection phase, the commit you lost will be there; you just need to find it. The garbage collection operation has, as mentioned, its own safeties; though...
