2. GIT Repository

The source code of DATAGERRY is managed in a GIT repository on GitHub:

2.1. Branches

We use several branches in our GIT repository:


The development of DATAGERRY is done in this branch. Every new feature, bugfix, … should be commited to that branch.


Branch with a stable version of DATAGERRY. All integration tests and CircleCI should have been passed before merging the development branch into master. A merge of development to master will usually be done at the end of a sprint.


Version branches should be created for every minor version, e.g. version-1.2 or version-1.5. It should branch from master. For each released version (e.g. 1.2.1), a tag should be set on a version branch. Bugfixes can be added to a version branch to prepare for a new bugfix release (e.g. 1.2.2)

2.2. Creating a Release

Releases should be versioned using Semantic Versioning.

To create a release, do the following steps:

  1. create a version-<minorversion> (e.g. version-1.2) branch from master

  2. set a tag with the full version number (e.g. 1.2.1) on the last commit on that branch

To create a bugfix release of an existing version, do the following steps:

  1. merge bugfixes in an exitsing version-<minorversion> branch

  2. set a tag with the full version number (e.g. 1.2.1) on the last commit on that branch

A tag should be set by creating a release in the GitHub WebUI. CircleCI will start automatically after setting a new tag and will create binaries, Docker images and documentation. Add the built tar.gz and binary to the GitHub release.


On our two plattforms files.datagerry.com and docs.datagerry.com, the latest symlink should be set to new tag.
