Software Releases

Gaudi (Marco Cl., Hubert)

  • Prerelease to be frozen on Friday, and the release made a week after (Friday, the 29th).
    Marco Ca. suggests to have a copy of the prerelease in LHCBDEV to simplify the testing (will be copied from the nightlies).
  • A bug and a patch still pending:
    • we agreed no to apply Patch #1675 (GaudiAlg::createAndPut)
    • Bug #33232 (EventCollectionSelector::rewind not implemented) cannot be fixed in time for Gaudi v19r8.
  • Hubert is implementing a pattern/document to install binary Python modules. To a void bloating the PYTHONPATH, he is also preparing a script to remove the non-existing directories from PATHs.

LHCb, Boole, Brunel (Marco Ca.)

  • Almost ready to go in DEV. Release due the 1st of March.

Gauss (Gloria)

  • Preparing configuration to allow to build Gauss with different version of Geant4.
    Doing it, Gloria noticed that the Geant4 library for pocesses is not complete in our build. This happens because there are a lot of subdirectories and not all of them are mentioned in the requirements file.

DaVinci (Juan)

  • Release last week. Without Loki on Win32 because it depends on the library KtJet, which does not compile on Win32 and is not supported anymore. Marco Ca. suggests we move to the new library (FastJet).

Online (Markus)

  • Online v4r6 released.
  • A new release already in the pipeline.

Panoramix (Thomas)

  • Guy is working on OpenScientist. He already solved few issues.

Release and Deployment (Hubert)

  • New release of Alignment.

Round Table

Discussed with Guy to have build of OpenScientist in the externals and based on the versions of the libraries that are there. The restructuring of Panoramix (scripts and python directories) have to be addressed too.
  • Problems with dictionary of std::map<std::pair<int,unsigned int>,unsigned int> >. Marco Cl. is investigating.
  • In GaudiPython evt.dump() produces a stack trace. Marco Cl. will have a look.
Marco Ca.
  • Somebody have to annonce the next Software Week and prepare the agenda (Thomas have already something). Thomas and Philippe will do it.
    • We have to defined the tutorials. A tutorial on configurables is needed (Marco Cl. will prepare it).
    • Ganga should present the status (about Configurables).
  • CCRC is proceding well. File transfer is OK, Brunel test jobs are working at all sites.
  • An outage of dCache at Lyon exposed a problem with ROOT/POOL/Gaudi: ROOT cannot read the file, and Brunel says "no more events" and exit successfully.
  • The printing of the time for each message, should use UTC instead of the local time. Hubert and Marco Cl. already had that discussion and the feature is available: it is enough to use "%u" insead of "%t" in the message format.
