Subjects

Issues from last meeting

Solved

  • Test Vidyo during Core Software Meetings
    • it is possible since there is a phone bridge (+41225330322)
    • a registration is required
  • Nightly build on gcc 4.6
    • running
    • we need the optimized version for testing
    • minor changes needed to compile
  • xrootd debug messages issue fixed
  • LHCbNightliesConfiguration updated (Thomas)
    • added scripts to automate the procedure

Pending

  • Proposal for split of GaudiSvc
  • DataQuality filtering by run
  • Warning when calling "SetupProject Dirac"
  • New version of Coverity analyzer
  • ICC builds (licensing)

News

Round Table

Gloria

  • gauss-dev is needed with some special configuration
    • will send a list of the requirements for the related LCG nightly slot
  • Rush release during the day
  • Clean up of AppConfig?
    • agreed to create a v3b for backward compatibility and start from scratch in the trunk (to be announced at the PAC)

Marco Cl.

  • Improvements to tag_package: it can create tags from branches and tag projects (project.cmt)
    • the twiki page must be updated
    • the script to create branches is missing: the code is essentially the same as tag_package, but it is better to have a different name (branch_package)
  • Discussed with Marco Ca. the possibility of hiring an ISIMA student to work on a "Release Manager Workbench"
    • description to be prepared

Joel

  • Migration of LHCbDirac to Dirac v6
    • use the next two weeks (before large MC11 production)

Hubert

  • Deployed LbScripts v6r6p1 (dev)
  • Philippe had a problem with the CRLs (Certificate Revocation Lists) on CERNVM
    • documentation problem (he used the wrong directory): fixed (CernVM)
  • Problem with Python 2.6 on SLC6 (conflicts between the system library and the distributed one)
    • a solution has been proposed to be included in LCGCMT
    • shell we move to Python 2.7? -> let's test it

Ben

  • Testing the compilation with '-O3' on gcc 4.3 (next will be 4.6).
  • Working on the gcc plugin to replace gccxml (from Stefan's code).
  • Preparing XML to describe the list of known projects/packages, instead of the current hard-coded one in LbScripts.

Illya

  • New distribution model of SQLite
    • couple of minor changes (no need to release them yet)
    • Marco Cl.: few test needed before going in production
    • Marco Ca.: once we are sure that the system works, we can back-port the changed to the v6 series

Alex

  • New release of Rivet
    • includes the first LHCb analysis
  • Preparing a new analysis
  • New Pythia8: fixed the conversion to HepMC (units mismatch)

Thomas

  • Problem starting the nightlies by hand in with gcc46 (wrong Python). Under investigation.
  • Working to get warnings in the nightlies summary when running out of space in the on AFS.
    • it should not be a problem for a while because now the .o and .a files are not copied
