Training Agenda
• Version Control History, GIT Design Goal
• GIT Extension Installation and Setup
• GIT Concept and Terminology
• GIT Daily Usage in SVN way
• Create your own GIT repo (local &
remote)
• New GIT feature and further more manual

Version Control History
 manually keep track of versions of code! (1960s)
 keep lots of versions in one file! (1972, SCCS)
 You can each have your own copy checked out! (1982,
RCS)
 version multiple files at once! (1986, CVS, atomic by
Subversion 2000)
 shared repository can be on a remote machine! (1994,
CVS with )
 open source version control hosting! (1999,
SourceForge)
 no central repository! (2005, GIT)
 When you checkout that’s a fork too, and you can do
that in public! (2008, GIThub)

GIT & GitHub History
 Torvalds wanted a distributed system that he could
use like BitKeeper, but none of the available free
systems met his needs, particularly his performance
needs. From an email he wrote on 7 April 2005 while
writing the first prototype.
 GitHub is a web-based hosting service for software
development projects that use the Git revision
control system. GitHub offers both commercial plans
and free accounts for open source projects.
According to the Git User's Survey in 2009, GitHub is
the most popular Git hosting site.

GIT Design Goal
• Take CVS as an example of what not to do; if in
doubt, make the exact opposite decision.
• Support a distributed, BitKeeper-like workflow
• Very high performanc and strong safeguards
against corruption, either accidental or malicious

GIT Extension Design Goal
• GitExtensions is a shell extension, a Visual Studio
2008 / 2010 plug-in and a standalone GIT
repository tool.
• Great tools enable you think and work in Unix style
gradually

GIT Extension Installation – All User
 http://code.google.com/p/gitextensions/ (download
URL)

GIT Extension Installation – Both

GIT Extension Installation - Integration

GIT Extension Installation - PuTTY

GIT Extension Installation - KDiff3

GIT Extension Installation – MsysGIT

GIT Extension Installation – Bash only

GIT Extension Installation – cross-platform

GIT Extension Setup
GIT Extension  Settings  Settings to fill:
 User Name
 eMail

GIT Email your Public key to Admin
• Copy selection text
and email to your
Admin
• Save private key
because you need
private key to login
latter
• Loss private key
need regenerate
private key and resent
public key to Admin

GIT clone your first repositories to test

Repository to clone: gitolite@cvpscmip01:testing

GIT Commit your first change to test

GIT Daily Usage in SVN way
 Clone (SVN Checkout)
 Commit (in Local!)
 Push (SVN Commit)
 Pull (SVN Update All)
 gitK (SVN History)

gitK – a commit viewer for git

GIT Key Sales Point

• Very fast and user friendly
• Source Code Repository is
distributed, isolated, history
complete
• All action can run in Local except
pull and push
• Submit and rollback always success
(until pull and push)
• Can fix last submit very easily

Create your GIT repository in GIT Extension
Open Repopsitory  Your not GIT init yet folder  Initialize Repository

Add .gitignore for VS.NET intermediate files
Forgot any add ignore file and pattern in Subversion, now it’s a One-click only!
But don’t forgot to add ignore files
when you initial the repository!

Commit initial version of files

Push your repository to CVPSCMIP01
You can to put any repository to: (no need inform GIT admin!)
gitolite@cvpscmip01:/usr/[yourname]/[your_repository_name]

Your repository is also visible at Web!
Suggestion:
1. Work as own at first in your usr folder. (No need to inform GIT Admin)
2. Rise your project to root folder if it is company widely used and relatively stable. (Need GIT
Admin help)
3. Old Subversion project will moved to root folder by GIT Admin already

More GIT tricks need SSH and console now
Setting more description for your own repository:

6749@SHE127731 /d/git
$ echo "A semi-auto MES Yield Limit Batch setting tools used in SPAS 125-001" | ssh
gitolite@cvpscmip01 setdesc usr/eri
c/YieldLimits-Change
Enter passphrase for key '/c/Users/6749/.ssh/id_rsa':
New description is:
A semi-auto MES Yield Limit Batch setting tools used in SPAS 125-001
