Development ModelΒΆ

The DIRACGrid Project is a pure open source project, advanced collectively by a distributed team of developers working in parallel on the core software as well as on various extensions. Everybody is welcome to participate.

The DIRACGrid project includes several repositories, all hosted in Github:

  • DIRAC is the main repository: contains the client and server code
  • WebAppDIRAC is the repository for the web portal
  • Pilot is not a DIRAC extension, but a new version of the DIRAC pilots (dubbed Pilots 3.0)
  • DIRACOS is the repository for the DIRAC dependencies
  • Externals is the OLD repository for the DIRAC dependencies, going to be superseded by DIRACOS
  • VMDIRAC is a DIRAC extension for using cloud sites
  • COMDIRAC is a DIRAC extension of its CLI
  • RESTDIRAC is a DIRAC extension that creates a REST layer for DIRAC services
  • DB12 is not a DIRAC extension, but a self-contained quick benchmark

The content of the other repositories at https://github.com/DIRACGrid have either been included in those above, or became obsolete.

This work must be supported by a suitable development model which is described in this chapter.

The DIRAC code development is done with the help of the Git code management system. It is inherently distributed and is well suited for the project. It is outlined the Managing Code with Git subsection.

The DIRAC Development Model relies on the excellent Git capability for managing code branches which is mandatory for a distributed team of developers. The DIRAC branching model is following strict conventions described in Branching Model subsection.

The DIRAC code management is done using the Github service as the main code repository. The service provides also facilities for bug and task tracking, Wiki engine and other tools to support the group code development. Setting up the Git based development environment and instructions to contribute new code is described in Contributing code subsection.

The DIRAC releases are described using a special configuration file and tools are provided to prepare code distribution tar archives. The tools and procedures to release the DIRAC software are explained in Making DIRAC releases subsection.
