GIT and its Extension TrainingEric Guo 2012-03-27
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 Users 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 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 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 ExtensionOpen Repopsitory Your not GIT init yet folder Initialize Repository
Add .gitignore for VS.NET intermediate filesForgot 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!
Push your repository to CVPSCMIP01You 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 alreadyhttp://cvpscmip01/usr/eric/MTtest-Assistant.git
More GIT tricks need SSH and console nowSetting 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" | sshgitolite@cvpscmip01 setdesc usr/eric/YieldLimits-ChangeEnter 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
