Version Control

The Genoviz project uses Git for version control and managing the release cycle. Note that for many years, Genoviz used Subversion for version control. We migrated from Subversion to Git in 2014.

IGB code base

IGB uses several libraries and sub-projects within the genoviz repository, including:

  • genometryImpl genomic data models shared by DAS server code and IGB
  • genoviz_sdk graphics framework that handles zooming, user interactions with data, etc.
  • igb the core IGB application
  • plugins functions added via plug-in interface, plug-ins are also called bundles (uses OSGi)
  • common - common classes used by the other projects

Structure of the repository

The repository has a master branch which is used as the "stable" development line.  The master branch is intended to reflect the latest released code or the latest release candidate code (i.e. minor bug fixes which will be included in the next minor release version).  The repository also has one or more active development branches.  These development branches follow the conventional naming structure of igb_version (e.g. igb_8_2).  Only when creating a major release will the active development branches be merged with the stable (master) branch.  Once merged with the master branch, the development branch is discarded and a new development branch is created with the next major release version.

Release Tags

When creating a release, a Git tag is created to annotate the point at which the release was built.
