10. Outline
● What is GIT?
● Why GIT?
● 15mins Tutorial
● Advanced Topic(s)

11. What is GIT?
● Distributed revision control and source code
management (SCM) system
● Designed to handle everything from small to
very large projects
● Designed and developed by Linus Torvalds for
Linux kernel development in 2005

13. Why GIT?
● Manage code changes by rename file will soon
reach its limitation, e.g.
– mycode-20140308.php
– mycode-201403080930.php
● Archive entire folder will make case even worse
– Need to extract before compare the changes
● Share progress with co-workers become
nightmare

14. Why GIT? (cont.)
● CVS
– Manage revision per file (rename not support)
– Remote repository server required (no local folder
offline management)
– Single commit management (other else contribute
by submit patches)
– TOOOOO OLD (well...)
● Used by Drupal during 7.x development cycle
● After Drupal 7 released, soon migrated to GIT

15. Why GIT? (cont.)
● SVN
– Manage revision per folder
– Remote repository server required
– Single commit management
– A bit better than CVS, but branching model still
looks crazy
● At least, we now have GIT, why still using SVN?

16. Why GIT? (cont.)
● GIT
– Manage revision per entire project
– Remote/local repository supported
● git init
● git add --all .
● git commit -am 'Initial commit'
● git log
● git status
– Distributed workflows
– Used by https://drupal.org/ since Drupal 7
– You also know https://github.com/, isn't it?

18. 15mins Tutorial
● Installation
– Debian/Ubuntu
● apt-get install git git-flow
– Mac
● brew install git git-flow
– Windows
● https://msysgit.github.io/

19. 15mins Tutorial (cont.)
● Basic commands
– git init
– git status
– git add
– git rm
– git commit
– git log

20. 15mins Tutorial (cont.)
● Remote commands
– git remote
– git push
– git pull

21. 15mins Tutorial (cont.)
● Advanced commands
– git diff
– git reset
– git checkout
– git branch
– git merge

23. Advanced Topic(s)
● Gitflow Workflow
● Continuous Integration (CI)
● Migrate to GIT from SVN
● Dropbox-like File Sharing

24. Gitflow Workflow
● The Gitflow Workflow defines a strict branching
model designed around the project release
● Developers work locally and push branches to
the central repo
● The only difference is the branch structure of
the project

29. Continuous Integration (CI)
● Test-Driven Development (TDD) or Behavior-
Driven Development (BDD)
● Combination with automated unit tests, e.g.
running phpunit per each GIT commit
– GitHub → Travis CI
– Stash → Bamboo

33. Migrate to GIT from SVN
● Prepare your environment for the migration.
● Convert the SVN repository to a local GIT repository.
● Synchronize the local GIT repository when the SVN
repository changes.
● Share the GIT repository with your developers via
Bitbucket.
● Migrate your development efforts from SVN to GIT.

35. Dropbox-like File Sharing
●
Dropbox
– Public cloud-based file hosting service
●
GIT
– Repository management with history
● SparkleShare
– GIT-based file hosting solution with history
– Just manage share and permission as normal GIT repository
– Support public (e.g. GitHub, BitBucket) or private (e.g. Stash, GitLab) GIT
repository
– Suitable for small size file sharing
– Dropbox-like operation, NO GIT command is required!!

38. Dropbox-like File Sharing (cont.)
● BitTorrent Sync
– Peer-to-peer file synchronization
– Over the Internet via secure, distributed P2P technology
● Unlike GIT-based solution:
– Suitable for large-size binary file hosting
– No complete history support
● How we use SparkleShare and BitTorrent Sync?
– BitTorrent Sync: Short-term working copy sharing
– SparkleShare: Long-lasting archive with history
