Follow-up from previous meeting

• Previous meeting was mostly dedicated to discussing 2 projects done by our student:
  • Move to logging
    • Works very well, already fully available from DIRAC v6r19
    • Also logs centralization looks like working OK (has to be seen in a production setup)
  • Move to JSON as serialization
    • a PR made, but broken. Developer left, we asked him to made it better

Current situation

DIRAC:

• v6r17p31 is the last production version
• v6r19-pre9 is out
  • Still problems with RSS
    • Fully re-implemented ResourceManagementDB (in a PR, should be reviewed and then merged straight away)
    • ResourceStatusDB should also be updated, but not for v6r19
  • Using externals v6r6p3 and lcgBundle v12r5
  • Today we'll make v6r19-pre10

WebApp:

• NTR

Pilot:

• We can introduce Pilot3 as optional from the SiteDirectors from next version

Externals:

• v6r6p3 still the latest (for v6r19) for both SLC6 and CC7

LCG bundles:

• New Version v12r8 compiled, it will be in testing with DIRAC v6r19 pre versions
  • CC7 version should be also OK, but librarians of GFAL2 won't make a statically compiled version, so it will need to use the local one.
  • We discourage its use for now

PyGSI:

• NTR

Release planning, tests and certification

Release planning:

• v6r17 series
  • NTR
• v6r19 series
  • v6r19-pre10 will be created including PRs already reviewed OK
  • It should use lcgBundle v12r8 and it should work also on CC7

Certification process: 

• One more certification hackhathon will be done tomorrow morning
  • Using trello and slack as usual

Weekly development(s) focus

• Deployment of DIRAC tarballs and of lcgBundle tarballs
  • lcgBundle creation should be moved to github [Joel]
    • Simple list of packages (RPMs) included in a file
    • Instructions and deployment tools should be added to the git repo too
    • other VOs if they want they can extend the package too
  • deploy on CVMFS:
    • it's unclear who as of today governs the dirac.egi,eu. We anyway think that all DIRAC versions should be deployed there
      • as of now it's just another place where the DIRAC tarball is dumped
      • we should investigate how to deploy a full release there
    • lcgBundle should be also uploaded to CVMFS
  • Move out of AFS: 
    • process need to be started to move tarballs and cfg files outside of AFS
    • EOSWeb is the advised solution but now it doesn't seem to be yet at production quality
    • http://lhcbproject.web.cern.ch/lhcbproject/dist/DIRAC3/globalDefaults.cfg still used by dirac-install.
    • We can't simply move the website above to EOS, as of now it hosts several websites. So a new one, dedicated to DIRAC has to be made. 

DIRAC: current PRs and tasks being worked on

• Some PRs need now to be reviewed and then we can prepare v6r19-pre10

AOB

• Next BiLD-Dev meeting will be held in 2 weeks (September 28)

LHCbDIRAC

• lb-run should always be called from an environment that is clean (saved within the pilot just after lbLogin)
  • This can be done even now [Federico]
• Philippe: before having a non-lb-run installation of LHCbDIRAC we need to have an intermediate solution
• Ganga should always call -c best
• All tasks have been added to https://its.cern.ch/jira/browse/LBCORE-1410
