A successful branch management

• http://nvie.com/posts/a-successful-git-branching-model/
  • Japanese

Why git?

• Subversion is dead.
• Branching and merging are no longer something to be afraid of

Two main branches

• Master
  • A production-ready state
• Develop
  • for the next release

Supporting three topic branches

• Feature
• Release
• Hotfix

Feature branches

branch off	merge back
delevelp	develop

Release branches

branch off	merge back
develop	develop and master

Hotfix branches

branch off	merge back
master	develop and master

git-flow

Git extensions to provide high-level repository operations for the branching model

https://github.com/nvie/gitflow

$ brew install git-flow

Init

$ git checkout -b develop origin/master
$ git flow init

Feature branches

• Start feature branch

    $ git flow feature start smartphone-version
  

  This means:

    $ git checkout -b feature/smartphone-version develop
  

• Finish feature branch

    $ git flow feature finish smartphone-version
  

  This means:

    $ git checkout develop
    $ git merge --no-ff feature/smartphone-version
    $ git branch -d feature/smartphone-version
  

Release branches

• Start release branch

    $ git flow release start 1.0
  

  This means:

    $ git checkout -b release/1.0 develop
  

• Finish release branch

    $ git flow release finish 1.0
  

  This means:

    $ git checkout master
    $ git merge --no-ff release/1.0
    $ git tag -a 1.0
    $ git checkout develop
    $ git merge --no-ff release/1.0
    $ git branch -d release/1.0
  

Hotfix branches

• Start hotfix branch

    $ git flow start 1.1
  

  This means:

    $ git checkout -b hotfix/1.1
  

• Finish hotfix branch

    $ git flow finish 1.1
  

  This means:

    $ git checkout master
    $ git merge --no-ff hotfix/1.1
    $ git tag -a 1.1
    $ git checkout develop
    $ git merge --no-ff hotfix/1.1
    $ git branch -d hotfix/1.1
  

Some problems

git-flow dose not concern for remote repository. Therefore, you need to sync to remote repository with hands.

Solution

Add -R | --remote option

https://github.com/iwata/gitflow

$ brew install https://github.com/iwata/gitflow/raw/master/git-flow.rb

Feature branches

• Start feature branch

    $ git flow feature start -R smartphone-version2
  

  This means:

    $ git checkout -b feature/smartphone-version2 develop
    $ git push -u origin feature/smartphone-version2
  

• Finish feature branch

    $ git flow feature finish -R smartphone-version2
  

  This means:

    $ git checkout develop
    $ git merge --no-ff feature/smartphone-version2
    $ git branch -d feature/smartphone-version2
    $ git push origin develop
    $ git push origin :feature/smartphone-version2
  

Release branches

• Start release branch

    $ git flow release -R start 2.0
  

  This means:

    $ git checkout -b release/2.0 develop
    $ git push -u origin release/2.0
  

• Finish release branch

    $ git flow release finish -R 2.0
  

  This means:

    $ git checkout master
    $ git merge --no-ff release/2.0
    $ git tag -a 2.0
    $ git checkout develop
    $ git merge --no-ff release/2.0
    $ git branch -d release/2.0
    $ git push origin master
    $ git push origin develop
    $ git push --tags
    $ git push origin :release/2.0
  

Hotfix branches

• Start hotfix branch

    $ git flow start -R 2.1
  

  This means:

    $ git checkout -b hotfix/2.1
    $ git push -u origin hotfix/2.1
  

• Finish hotfix branch

    $ git flow finish -R 2.1
  

  This means:

    $ git checkout master
    $ git merge --no-ff hotfix/2.1
    $ git tag -a 2.1
    $ git checkout develop
    $ git merge --no-ff hotfix/2.1
    $ git branch -d hotfix/2.1
    $ git push origin master
    $ git push origin develop
    $ git push --tags
    $ git push origin :hotfix/20111201-1234
  

Conclusion

1. Subversion is dead.
2. git-flow is very useful.
   • But it has some problems.
3. To use advanced git-flow is the solution.
   • Add -R | --remote option

One more thing

git-now is a command-line tool for light and temporary commit. It commits with a log message from time now and diff.
