The plan is to enable merging every time. If/when we can, we can try one of the more aggressive solutions.

Round Table

Thomas

  • Problems in the nightlies
    • inconsistency in AFS causing random errors (see INC176408).
    • problem with missing symbols due to bad LD_LIBRARY_PATH triggered by gcc46 client processes that were picking up gcc43 builds.
      Modified the code to avoid mixing of platforms.
  • lhcb-patches4 to be used for testing -pedantic builds. Problems due to misconfiguration: the documentation of the nightly build system needs some fixing.

Joel

  • Reprocessing running well.
  • Triggered the guy to replace the old lxbuild machines.
  • Finalizing the ISIMA requests. Send the project to the school and ask the students to register to ERT.

Marco Cl.

  • CMake configuration
    • introduced prototype of support for data packages
    • built up to Brunel v44r0 (on Gaudi HEAD) and tested successfully, including the build of a private partial project
    • working on the integration with getpack and SetupProject, followed by nightlies, mkproject, etc.

Stefan

  • Working on the visualization of the results of the profiling.
  • Will go to CSC in two weeks.

Alex

  • Committed QMTests (working on 32bits, at least).
  • Start to work on MC FSRs.

Ben

  • LbScript v7r2 tested as much as possible. Waiting for a test by Joel, then it can bydeclared 'prod'.

Liang

  • New global tag.

Gloria

  • Would like to distribute all the PDF data instead of only an extract (as we do now).
  • Should we start testing productions for upgrade in a centralized way? yes, if it's reasonable.
