Repository Management

This document attempts to record everything there is to know about repository management for the OSG.

Public repositories

We host four public-facing repositories at repo.opensciencegrid.org:

  • development: This repository is the bleeding edge. Installing from this repository may cause the host to stop functioning, and we will not assist in undoing any damage.

  • testing: This repository contains software ready for testing. If you install packages from here, they may be buggy, but we will provide limited assistance in providing a migration path to a fixed verison.

  • release: This repository contains software that we are willing to support and can be used by the general community.

  • contrib: RPMs contributed from outside the OSG.

These repos are updated by the mash script running on repo.opensciencegrid.org.

Internal repositories

In addition to the public repositories above, we host two repositories on koji.opensciencegrid.org. These are updated shortly after jobs are built into them or tagged into them. They are technically publicly accessible, but we discourage the public from using them.

  • minefield: This repository is a copy of development above.

  • prerelease: This repository is a staging area for software that is slated to be in the next release.

These repos are updated by the kojira daemon running on koji.opensciencegrid.org.

Build repositories

Warning

this section is out of date; the tags it references no longer exist.

The koji task in osg-build uses the osg-3.4-el6-build/osg-3.4-el7-build repo, which is the union of the following repositories:

  • Minefield a.k.a. osg-3.4-el6-development / osg-3.4-el7-development
  • The osg-el6-internal / osg-el7-internal tag (containing build dependencies we do not want to make public)
  • The dist-el6-build / dist-el7-build tag (consisting of the appropriate macros for %dist)
  • CentOS and EPEL

Koji will work from its internal cache of the above repositories (downloading the packages from the source), and will not update until the build repository is regenerated. By default, Koji does a groupinstall of the build group, then resolves the BuildRequires dependencies.

The tarball creation scripts use the osg-3.4-el6-release-build / osg-3.4-el7-release-build repo, which is the union of the following repositories:

  • Release a.k.a. osg-3.4-el6-release / osg-3.4-el7-release
  • The dist-el6-build / dist-el7-build tag (consisting of the appropriate macros for %dist)
  • CentOS and EPEL
