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.

Summary


This chapter showed us the various ways of exploring project history: finding relevant revisions, selecting and filtering revisions to display, and formatting the output.

We started with the description of the conceptual model of project history: the Directed Acyclic Graph (DAG) of revisions. Understanding this concept is very important because many selection tools refer directly or indirectly to the DAG.

Then, you learnt how to select a single revision and the range of revisions. We can use this knowledge to see what changes were made on a branch since its divergence from the base branch, and to find all the revisions which were made by the given developer.

We can even try to find bugs in the code by exploring the history: finding when a function was deleted from the code with a pickaxe search, examining a file for how its code came to be and who wrote it with git blame, and utilizing semi-automatic or automatic searches through the project history to find which version introduced...
