Git is a source control management system like SVN or CVS but with additional features making it faster and more powerful. It allows for offline work, distributed workflows across multiple repositories, and easy branching and merging of code. Key commands include git add to stage files, git commit to commit changes, and git push to push commits to a remote repository. Additional features include stashing work, rebasing branches, and bisecting to find bugs. While more powerful, Git can also be more complicated than other systems.

An intro to Git Source Control Management

2. Say what?
Source Control Management
like SVN, CVS,.. but better!
Linus Throvalds (april 2005)
Linux Kernel
Junio Hamano (july 2005)
a stupid person!

3. Ok, but why?
Offline
Distributed
Branching
Because it’s fucking fast, that’s why!

4. How git works Offline
world
local

5. How git works Distributed
server
local
local local

6. How git works Branching
feature commit
master commit commit commit merge
feature commit commit

7. Repository
unstaged
git add <files>
local remote
staged
repository repository
git commit git push

8. Our Workflow
git checkout -b cool_feature
do some fun code stuff, drink a mojito
git fetch master
git rebase origin/master
git checkout master
git merge cool_feature

9. Useful commands and files
git init ‣ repository setup
git add ‣ add files to queue for next commit
git commit ‣ commit queued files
git push ‣ push commit(s) to remote repository
git pull ‣ fetch changes from remote repository
git clone ‣ clone repository into a local directory
.gitignore ‣ ignore specific files by adding them here

10. Cool features
Uhm.. Okay...

11. Cool features stash
do some cool stuff
git stash
fix an irritating bug
git commit -a -m “Farewell, you bug!”
git stash apply
do some more cool stuff

12. Cool features rebase
fetch changes from another branch
feature commit 3
master commit 1 commit 2 commit 4

13. Cool features rebase
fetch changes from another branch
1234
feature commit 3
master commit 1 commit 2 commit 4
124

14. Cool features bisect
Find the code change that introduced a bug
git bisect start ‣ start bisect session
git bisect bad ‣ mark current revision as bad
git log ‣ search a working revision
git bisect good revision ‣ mark the working one as good
git bisect good/bad ‣ bisect until you find the bug

15. Cool features cherry-pick
Apply a change from another commit into current branch
git log ‣ search the right commit
git checkout branch ‣ checkout the branch you want
git cherry-pick revision ‣ apply commit into branch

17. Git vs SVN
Git SVN
Distributed Single Repository
Branches partial checkout
Performance Access Control
Repository size Shorter revision numbers
Powerful,
more GUI tools
little more complicated

18. git-svn
using git local if you have a remote svn repository
use git on your local machine
staging
seperate commits
branches
push your commits to your svn repository
