Overview

This section (overview and subchapters) was made possible by the work of Paolo Venturi and Davide Giudici: it is strongly based on their training course about Git.

Git is a version-control system created in 2005.

It is very versatile as far as it regards branches and reposoitories, rollbacks and so on.

It is supported by many clients and IDEs, and it is used by a very active community.

Basic concepts

  • A GIT project is an indivisible unit

    • Git works always with the entire source code of the project
    • There is no checkout of a single file or directory

  • Peer to peer system

    • Git works on a local copy of the entire repository
    • The network architecture is customizable (we can choose a distributed or a centralized network model)

  • Storage integrity

    • Git stores files in their entirety
    • Git does not memorize the changes of a file: it creates a "smart" snapshot of the repository state at a given commit

  • Ramifications

    • Strong orientation towards non-linear development
