OSG Software Team

  • Kubernetes hackathon today
  • AI (Mat): Package xrootd-tcp-stats plugin (SOFTWARE-4744)
  • AI (Mat): Convert osg-pki-tools to Python 3
  • AI (Brian): Build XRootD with Brian's patch
  • AI (Brian): Set osg-flock VOOverride to "osg"


The HTCondor OAuth Credmon's dependencies only have Python 2 versions on EL 7; we'll need a python-scitokens version for Python 2, even if it's security-fixes only.

Support Update

  • BNL (Mat): debug authentication issues when accessing an xrootd server using WebDAV
  • Lancium (BrianL): moved them over to Singularity-in-Singularity and had to adjust their bind mount settings
  • GATech (Derek): Gratia probe is reporting a lot of groups.
  • UConn (BrianL): job router config not correctly converted from old syntax to new syntax: extra quotes in the grid resource caused connection failure

OSG DevOps

  • Stashcp now supports recursive downloads. Release upcoming. How should we handle packaging of stashcache-client in OSG repos?
    • Some stashcp debugging is in order for proxy support.
  • xrootd-monitoring-shoveler running at UCSD and Florida (RPM) and UNL (K8s)
  • Go packaging:
    • No network for builds, so deps come from EPEL or from a dependency bundle.
    • Derek will investigate what dependencies are already in EPEL (likely all of them)
