12. What is Git?

13. Git is an open source, distributed version control system designed for speed and efﬁciency

14. version control

15. mercurial (hg) bazaar subversion (svn) version control concurrent version system (cvs) perforce visual source safe

16. SoS mercurial (hg) bazaar subversion (svn) version control concurrent version system (cvs) perforce visual source safe

17. SoS mercurial (hg) “not bad” bazaar subversion (svn) version control concurrent version system (cvs) perforce visual source safe

18. SoS mercurial (hg) bazaar subversion (svn) version control concurrent version system (cvs) perforce visual source safe “kill self”

19. git mercurial (hg) bazaar subversion (svn) version control concurrent version system (cvs) perforce visual source safe

21. git-scm.com

23. Fully Distributed

24. (almost) everything is local

25. which means everything is fast every clone is a backup work ofﬂine

26. No Network Needed Performing a diff Viewing ﬁle history Committing changes Merging branches Obtaining other revisions of a ﬁle Switching branches

29. Immutable

30. (almost) never removes data

31. Snapshots, not Patches

47. Basic Git

48. First Steps

49. $ git config --global user.name “Scott Chacon” $ git config --global user.email “schacon@gmail.com”

50. Getting a Repo

51. Create One

52. git init

53. $ touch hello_world.rb $ git init $ git add . $ git commit -m ‘first commit’

63. Clone One

64. git clone

65. $ git clone git://github.com/schacon/ticgit.git Initialized empty Git repository in /private/tmp/ticgit/.git/ remote: Counting objects: 591, done. remote: Compressing objects: 100% (267/267), done. remote: Total 591 (delta 253), reused 587 (delta 252) Receiving objects: 100% (591/591), 73.05 KiB, done. Resolving deltas: 100% (253/253), done. $ cd ticgit/ $ ls LICENSE! ! Rakefile! examples! note! ! ticgit.gemspec README! ! bin! lib! spec ! ! $

68. $ git clone git://github.com/schacon/ticgit.git Initialized empty Git repository in /private/tmp/ticgit/.git/ remote: Counting objects: 591, done. remote: Compressing objects: 100% (267/267), done. remote: Total 591 (delta 253), reused 587 (delta 252) Receiving objects: 100% (591/591), 73.05 KiB, done.

69. A Basic Workﬂow

70. A Basic Workﬂow Edit ﬁles Stage the changes Review your changes Commit the changes

71. working directory git add index git commit repository

72. a working copy working directory of your project git add index git commit repository

73. working directory git add index git commit object database repository

74. working directory git add index “staging” git commit repository

104. You have to stage a ﬁle after you edit it

107. $ git add app.yaml main.py $ git status # On branch master # Changes to be committed: # (use "git reset HEAD <file>..." to unstage) # # modified: app.yaml # modified: main.py #

109. git commit

112. $ git commit # Please enter the commit message for your changes.

192. Why is this cool?

193. non-linear development

194. • clone the code that is in production • create a branch for issue #53 (iss53) • work for 10 minutes • someone asks for a hotﬁx for issue #102 • checkout ‘production’ • create a branch (iss102) • ﬁx the issue • checkout ‘production’, merge ‘iss102’ • push ‘production’ • checkout ‘iss53’ and keep working

195. production origin/master C1 C0 git clone

196. production origin/master C1 iss53 C0 git checkout -b iss53

197. iss53 production C2 origin/master C1 C0 git commit
