Brian Leonard presents at Tech Days, Hyderabad, March 2010.
Source Juicer (http://jucr.opensolaris.org) is a recently deployed Opensolaris website who's purpose it is to encourage community porting efforts for the solaris platform. Opensolaris now has two community governed IPS package respoitories, /pending and /contrib and Source Juicer delivers software into these repos. Source Juicer has two main components, the first is a web application that is responsible for accepting and managing community initiated package submissions. When a submission is made, a review thread is created allowing for community members comments and review of the package. At the same time as generating the review thread, the system attempts to build the package and if successful, it is published into the /pending repository. Once the submission has received two positive votes from designated approvers the package is promoted to the /contrib repository, where it is available as a community supported package. The second component is called BuildGrid, which builds and publishes packages. BuildGrid uses a number of Opensolaris technologies, namely ZFS, Zones, IPS & Pkgbuild to build the packages. The BuildGrid requires at least one spec file and one copyright file to successfully build a package. Its scalable and robust architecture allows for the continuous and simultaneous building of packages for different releases and different architectures. Included in the future plans of the Source Juicer development team is the goal to migrate the current release engineering process for the desktop consolidation to the Source Juicer application. This will provide the twin advantages of enhancing community involvement with the Desktop components of Opensolaris and moving away from the existing lengthy and cumbersome nightly builds to a continuous package-by-package build. Also covered in the talk will be a a look at the origination of the project, a detailed look at the architecture and a brief walk-through of the creating and reviewing of a submission, plus the building and installing of a package.
