Round Table

Marco Cl.

  • Coverity
    • started the web interface after the upgrade of the defects database, but the defects are not visible/searchable
    • let's wait to see what happens when we resurrect the analysis jobs before trying to re-migrate the DB
  • CMake
    • fixes for relocatability (lb-run + Gaudi), requires Gaudi and LbScripts
  • Gaudi
    • added warning for duplicated properties (in derived classes)
    • quick boot without GaudiPython (GAUDI-986), exposing problems hidden by PyROOT
  • Git mirrors (LBCORE-729)
    • added more projects
    • need to define merge policies

Markus: can we have a debug build with -O0?
After some discussion, we agreed to add one platform (id) that is built with "-g -O0" (only for the Online use case). This platform will only be built in the release (not in the nightlies).
(LHCBPS-1394)

Given the timescale for the release of the LHCb software stack we scheduled the release of Gaudi for the end of next week (with new LCG).

Marco Ca.: what is the status of LoKi functors cache?
Still not integrated with the build system, and unlikely Marco Cl. can work on it before after the workshop.

Joel

  • Build machines 161-163, 171-173 will be retired on Friday

Marco Ca.: can we still use build machines for private builds/tests?
Yes, but we should investigate other possibilities, like lxbatch or private VMs.

Ben

  • Issue with SFT JIRA: cannot add watchers (if you do not know the user name)
  • IT circulated a poll about usage of Trac, with suggestions to move to Git
  • Release of LbScripts soon

Marco Ca.

  • Computing Workshop in two weeks
  • CHEP paper dead line the 15th

Markus

  • Still problems triggering a release.

Illya

  • Working on task scheduling on
  • Submitted to IEEE an abstract

Liang

  • Patches on DDDB and LHCBCOND for the split Hlt
