 Version management with git makes branching and merging much easier than older versioning systems such as SVN.
 This allows a wide variety of branching strategies and workflows.

 Frequently the reaction to this problem is to adopt a standardized pattern such as [git flow](http://nvie.com/posts/a-successful-git-branching-model/) and [GitHub flow](http://scottchacon.com/2011/08/31/github-flow.html)
 We think there is still room for improvement and will detail a set of practices we call GitLab flow.

 In GitLab it is common to protect the long-lived branches (e.g. the master branch) so that normal developers [can't modify these protected branches](https://gitlab.com/gitlab-org/gitlab-ce/blob/master/doc/permissions/permissions.md).
 So if you want to merge it into a protected branch you assign it to someone with master authorizations.

 Martin Fowler, in [his article about feature branches](http://martinfowler.com/bliki/FeatureBranch.html) talks about this Continuous Integration (CI).
 At GitLab we are guilty of confusing CI with branch testing. Quoting Martin Fowler: "I've heard people say they are doing CI because they are running builds, perhaps using a CI server, on every branch with every commit.
 That's continuous building, and a Good Thing, but there's no integration, so it's not CI.".

+If your feature branches commonly take more than a day of work, look into ways to create smaller units of work and/or use [feature toggles](http://martinfowler.com/bliki/FeatureToggle.html).
 As for the long running branches that take more than one day there are two strategies.
 In a CI strategy you can merge in master at the start of the day to prevent painful merges at a later time.
 In a synchronization point strategy you only merge in from well defined points in time, for example a tagged release.
