Follow-up from previous meeting

  • DUW 4 weeks ago
    • feedbacks in https://docs.google.com/forms/d/1C67pOX0UwulLsh-LZeDFq4IaJlmcCmRlTSqtYmTSdeM/
  • PR (#3713) for fixing the infamous "invalid action proposal" by speeding up the handshake and not looking up the user/group in the baseStub: backported to v6r19, working as expected. In production for many now.
  • does the OSCompatibility section in CS need to be kept up-to-date? Not sure, to be checked.

Current situation

DIRACOS:

Documentation

  • At the DUW we agreed on putting more technical info in the docstrings of the DIRAC components
    • Andre' has added in PR #3723 the technical documentation to start/administer two TS agents. 
    • Anyway we agreed to not use the tabular format, but rather to add some snippets of the CS
    • This PR will "set the tone (the format)" on how to write this technical documentation.

DB12:

  • NTR

Release planning, tests and certification

Release planning:

  • v6r19 series

  • v6r20 series
    • v6r20p3 created today, ready for v6r20p4
      • #3726, #3725, #3722
  • v6r21 series
    • v6r21-pre1 is out
    • for this series, we agreed that DIRACOS will be used
    • also WebApp 4.0 can be used
    • this takes us to name this release v7r0
    • the list of feature request is already getting closed

Certification process: 

  • v6r21 certification: 
    • v6r21-pre1 installed already in DIRAC certification setup
    • https://jenkins-dirac.web.cern.ch/ is open to registrations for who needs it or wants it

Weekly development(s) focus

  • dirac-install ++ follow-up
    • based on task #3517
    • ongoing PR: #3678
    • we need to be careful to keep the backward compatibility, as many instructions point to use the version found in integration branch.

DIRAC: current PRs and tasks being worked on, or topics from Google forum

  • PRs:
    • #3703 on new production system: several comments, not for today (Luisa not present). Won't be merged, for now
    • #3724: can be merged anyway, the actual deployment should anyway be done by hand (DB operation)
    • #3723: Multi-VO transformation system. Not much code, actually. No need for changes at the DB level 
  • Forum:
    • GridPP installing the transformation system. Quite some work to actually fix the CS correctly. Interested in #3273.

DIRAC communities roundtable

  • BES: 
    • Moving to v6r20 next week
  • CLIC:
    • mostly testing multiVO TS
  • LHCb: 
    • NTR

      • Chris submitted a staging transformation that showed few issues, PR coming today

        • we need to keep the "old way" of installing because anyway this https://its.cern.ch/jira/browse/LBCORE-1410 is not completed
