Deployment Platform/Software

Deployment Platform version cycle: | 1.0 | 1.1 | 2.0 |

Software Map

The whole software within the Harmonic Distribution is structured as: Base software Provided from Sweets Distribution in form of native packages. Base software is separated by targeted audience: Using oriented For regular usage. This kind of software exists in two dimensions: By purpose: Client side Desktop - Desktop Environment for Sugar Learning Platform. Server side Server Kit - to form school servers. By the supporting time: Short-term support (STS) Targeting to individual usage and based on Sucrose six months release cycle. Long-term support (LTS) Targeting to Sugar deployments that can't switch between Sucrose releases every six months. Development oriented Doers' Kit - targeting to developers who code within the Sugar Learning Platform. Community software The rest of software created on top of the Base one. In contrast to the Base, this kind of software is being provided via Sugar Network.

Sweets Distribution

This is a 3rd party repository with Base Software packages built against all supported platforms. These packages are being built on Sugar Labs instance of Open Build Service and formed in several projects:

• SweetsDistribution
  Contains all supported platforms as OBS repositories and system packages for upstream projects (not Base software) that are not well packages in supported platforms.

• SweetsDistribution:Factory
  OBS project with development packages that are intended for testing only.

• SweetsDistribution:<SUCROSE-RELEASE>
  Stable STS/LTS releases of Harmonic Distribution.

After building, OBS uploads resulting packages to download.sugarlabs.org site. Follow Sweets Distribution instructions to setup them for individual usage.

Desktop

Components:

For detailed information, see Server Kit's home page.

Doers' Kit

Sugar Doers Kit (SDK) is a set of tools and libraries to help people code in Sugar.

Components:

• Sweets, Zero Install based Package Management System for Sugar.
• sugar-lint, utility to lint various source files.
• gatch, support long or ever standing, all time being on top, downstream patchset for the base branch in a Git repository.
• Sugar via Sweets, several Sucrose versions via Sweets.

Sources:

• SDK project.

Sugar Network

Components:

• sugar-network.
• Web UI.
• Contributor Hub.

Sources:

• Network project.

Distribution via Sugar Network

The high-level overview is looks like:

• software creators
  upload source bundles to the Sugar Network; only sources, even if it is binary based activities;
• Sugar Network
  if uploaded software needs building, it will send it to OBS;
• on users side
  Sweets library will:
  • read Sugar Network to find out information about implementations of software that user requested to launch;
  • according to the local environment, it will download proper implementation;
  • if there is no proper binary implementation, it will download sources and will build them in local environment.
