ROOT Review planning
Root Planning Meeting 11-09-2013
Present: the Root team, Daniel Funke, John Harvey, Andreas (R), Bill (R), Valeri (R)
Executive Summary:
o ACTION Valeri: Run the script of Axel to check which libs in Atlas use Reflex in order not to miss dependencies in the future
o ACTION Danilo&Bill: Follow up the genreflex crash iterating to achieve a fix
o ACTION Danilo: Follow up the CMS builds with CMS SDT experts (Giulio Eulisse, Shahzad Muzaffar and David Abdurachmanov)
Axel
o Import of new LLVM: the priority of this is lower than the bug fixes. After those, the import will happen and THtml will be fixed (this latter also depends on the progress of Vassil)
Wim
o Axel: What is the link between cppyy and ROOT6?
- For Cool: we can lift the dependency on ROOT
- For Atlas: very desirable according to the chief architect
We conclude that we wait a test of this new feature by CMS. If the test is successful, given that the change is very transparent and allows for better scalability in the future, we will proceed with the inclusion in v6.
Valeri
o Four weeks at cern from 12th of October
o 1 Month is needed to make the final test of Atlas_Reflex_free against ROOT5
o ACTION: Run the script of Axel to check which libs in Atlas use Reflex
Bill
o CMS FW Core built against ROOT6: some issues, many of which expected.
o Genreflex: crashed in many places, segmentation fault.
- ACTION: Danilo&Bill Follow this up iterating to reach a solution
o Reflex still used in some places: under control, will be fixed
o Some interfaces changed, easy to fix
o Shazhad, Giulio, David are at cern and taking care of the build
- ACTION: Danilo follow this up with the CMS team
o Absent in one week for 2 weeks, Paul will probably be the person reporting at the meeting
