Decentralized

Branching Strategy

Decentralization is the process of redistributing or dispersing functions, powers, people or things away from a central location

http://en.wikipedia.org/wiki/Decentralization

The plan

Instead of only having a master branch, we introduce a "develop" branch. this becomes the main branch AKA "the integration branch".

 

Any automatic nightly builds are built from this.

Supporting Branches

  • Feature
  • Release
  • HotFix
marcosp @ ~/Projects/www/www.hostelbookers.com
$ git checkout -b jira-1234 develop
$ git add <some-file> 
$ git commit
marcosp @ ~/Projects/www/www.hostelbookers.com
$ # many more commits
$ git pull origin develop
$ git checkout develop
$ git merge some-feature
$ git push
$ git branch -d some-feature

Commands

What have we done?

  • Enabled one or more developers to work on a feature
     
  • Allowed them to independently ship that feature
     
  • Allowed for hotfixes to exist at any time
     
  • Versioned our application to allow for continuous release

Where to go from here?
