Repository Control System using Git Prepared By

What is version control ?Version control is a system that records changes to a file or set of files over time so that you can recall specific versions later.

2

Local Version Control SystemsMany people’s version-control method of choice is to copy files into another directory (perhaps a time-stamped directory, if they’re clever).

This approach is very common because it is so simple, but it is also incredibly error prone.

Local Version Control Systems

4

Centralized Version Control Systems❖ These systems, such as CVS, Subversion, and Perforce, have a single server that contains all the versioned files,

and a number of clients that check out files from that central place.

❖ This setup offers many advantages, especially over local VCSs. For example, everyone knows to a certain degreewhat everyone else on the project is doing.

❖ Local VCS systems suffer from this same problem – whenever you have the entire history of the project in asingle place, you risk losing everything.

Distributed Version Control Systems❖ This is where Distributed Version Control Systems (DVCSs) step in. In a DVCS (such as Git, Mercurial, Bazaar or

Darcs), clients don’t just check out the latest snapshot of the files: they fully mirror the repository. Thus if anyserver dies, and these systems were collaborating via it, any of the client repositories can be copied back up tothe server to restore it.

❖ if any server dies, and these systems were collaborating via it, any of the client repositories can be copied backup to the server to restore it. Every clone is really a full backup of all the data.

Repository❖ Generically refers to a central place where data is stored and maintained.

❖A repository can be a place where multiple databases or files are located for distribution over a network, or arepository can be a location that is directly accessible to the user without having to travel across a network.

❖Example : Git, Mercurial, Bazaar or Darcs

About Git❖Git is a version control system that is widely used for software development and other version control tasks.

❖ It is a distributed revision control system with an emphasis on speed, data integrity, and support for distributed, non-linear workflows.

10

A Short History of Git❖ In 2002, the Linux kernel project began using a proprietary DVCS called BitKeeper.

❖ In 2005, the relationship between the community that developed the Linux kernel and the commercial companythat developed BitKeeper broke down, and the tool’s free-of-charge status was revoked.

❖Since its birth in 2005, Git has evolved and matured to be easy to use and yet retain these initial qualities.

11

Working Mechanism in GitThe three main sections of a Git project: the Git directory, the working directory, and the staging area.

12

How to use Git❖Almost Every IDE support git plugin . Installing this plugin we perform git operation through UI console their

Like Android Studio, Eclipse, Netbeans etc.

❖Using Command we can perform following operation . In this slide we perform git operation using Git console .

Bonobo Git Server❖Bonobo Git Server for Windows is a web application you can install on your IIS. It provides an easy management

tool and access to your git repositories that are self hosted on your server.

❖Bonobo Git Server is an open-source project as it is licensed with a MIT License.

❖Bonobo Git Server is a free git server for Windows and it should stay free.
