Notes: Additional “urgent” releases may be scheduled for the 4th Tuesday of each month. The Testing date is when acceptance testing will be scheduled for releasable packages; if a package is added after this date, it may not be possible to schedule adequate testing time, thereby forcing it into the next release.

OSG Software Team

  • Two weeks until August development freeze
  • Major LCMAPS VOMS plugin issues plaguing multiple sites, causing extensive downtime

Discussions

  • The root cause of the LCMAPS VOMS segfaults appear to be due to memory issues in the proxy verification module. BrianB hopes to have a fix by the end of the day.

Support Update

  • Clemson, IIT, UConn (BrianL) - LCMAPS VOMS plugin issue above

OSG Release Team

  • Tim Theisen is handling the July 11th release
  • Release tomorrow

Discussions

  • Operations will be adopting a more flexible release schedule, at least for changes transparent to the user
  • Cert update incoming; Edgar will help test it while Suchandra is at PEARC. In the future, it may make more sense to test cert packages in an automated fashion \minus; perhaps with rpmdiff.

OSG Investigations Team

This Week

  • Derek at PEARC this week and the OSG User School next week
  • Contributing to CVMFS and looking at he LIGO use case again
