History of Git'a
2005 - Linus Torvalds starts Git
2006 - Proof-of-concept, quite unusable
2007 - Index reader, quickdiff
2008 - Add history view, commit, push/fetch
2009 - Eclipse decides on Git; moved to Eclipse.org
3/2010 - Released 0.7.0
Diff/Merge
Automatic IP Logs
Preliminary merge algorithm implementation (not really usable for now on)
6/2010 - Released 0.8.0
Usability Improvements

Git vs. CVS/SVN
● Distributed (but …) ● Centralized
● Ability to work off-line ● no
● Full local history ● no
● Versions are described ● Numerically described
using SHA-1 versions
● Fast and lightweight ● Every branch is a full copy
branches of repository
● Checkout on repository ● Checkout on file/catalog
level level
● Complex tag's ● Simple tag's

How Git works?
Structure of .git
extensions
global exclude file
record branch changes
object storage
local branches
default main branch
remote tracking branches, divided by repository
default remote repository
default remote branch
configuration for this repository
tip of current branch
cache for staging changes for next commit

Demo Time!
15

First demo
Create and share project locally.
16

Second Demo
Working with remote project.
We'll use gitosis as a Git server and CGit for on-line
project presentation.
17

Third demo
Benefiting from distributed VCS.
Using Git and Gerrit for keeping project in good
shape.
