    Apologies:

    Follow-up from previous meeting

    • Ran hackathon last week on v7r2-pre27:
      • trello board here
      • added EnableActivityMonitoring option to REA (using MonitoringSystem)
        • started testing it, some issues discovered, fixed in PR.
      • https functionalities not yet tried out

    DIRAC communities roundtable

    GridPP:

     Daniela

    • NTR

    CLIC:

    • No change in the iLCDirac setup, still v6r22

     Federico

    EGI:

     Andrei

    • Allocating enough resources in Lyon, migrating everything including the databases, and only after starting to merge the services with the ones in France Grilles (no urgency though). Should be an interesting exercise.
    • Sorted out the issues with certificates, now will start migrating to v7r1.

    France Grilles:

     Andrei

    • Still on Pilot2
    • Starting to migrate to ES.
      •  Federico: use v7r1 for ES7 compatibility

    Belle2:

     Hideki

    • DIRACOS migration completed successfully
    • Preparing to rucio migration
      • stop tomorrow, make a LFC dump, move to Rucio, restart Monday.
      • will report how it goes

        • CHANGE: (#4873) default generated bashrc does not overwrite X509* variables if already set
        • NEW: (#4873) Add DIRAC_X509_HOST_CERT and DIRAC_X509_HOST_KEY environment variables
      • WMS

    • *v7r1p24:
      • only fixes
    • v7r2-pre27:
      • more fixes

    DIRAC projects

    DIRAC:

    PRs

    • [v7r2] Fully support setuptools

      • Large PR because all scripts are changing
      • This is anyway “only code”, logic is staying the same. So it should be “easy” to test
      •  Andrei: each extension will become a pip-installable extension, being this LHCbDIRAC or VMDIRAC
      • pip-install on top of DIRACOS2 or “on-your-own” pip-installable.
      • scripts get renamed, as ‘-’ are not allowed, so moving script names from useing ‘-’ to using ‘_’
        • dirac-service, dirac-agent, etc are hardcoded in the run files
        • will need some transition docs anyway, and some scripts to address it, but for the moment we will keep both names

    • [v7r1][WIP] docs: user manage, proxy manager for addressing https://github.com/DIRACGrid/DIRAC/issues/4702

      • some of the documentation requested is not for v7r1, rather for v7r3
      • What’s prepared should be close to final anyway
      • Christophe should look again into it

    Issues

    • PR documentation on nginx configuration was removed, will create a new one.
