Present: Marco, Peter, David A., David L., Graeme, Marcin

Activities of the ROOT team:

o Digesting the input received at the Workshop (thanks to all the participants!) - full day internal meeting dedicated to it

o Finalise the new TProcPool approach to multiprocessing (OSx support, // TTree/TChain processing)

o Minor fixes in the dictionary area

o Major fix in the fix of naming - not yet committed

 

Marco Cl.

o Only a new bug report: infinite recursion in a signal handler ROOT-7659

o Selecting two typedefs selecting the same class triggering a warning.

Peter

o Enthusiasts using ROOT6 for analysis: some changes in the analysis component of AliROOT.

o Some changes were necessary, for example libraries loaded and classes used afterwards.

o Waiting for feedback about memory consumption - Massif sent 4 weeks ago.

David

o Issue of 6.04 patches: bogus errors about redefinitions. This appeared in the past ~10 commits. Philippe following that up.

o Move gcc5: define private/public and so on. The only production code is in Fireworks. Waiting for a mail of David listing the interfaces still protected or private.

o TTreeReader ticket open assigned to Axel (ROOT-7601)

o A new clang patch for supporting gcc5 abi is available: things are moving there!

Marcin

o ROOT-7181 still open

o Collection proxies: not compatible - they did not have any checksum. Solved with a workaround by Philippe and Philippe will fix this for the future.

o First Physics validation passed!

o Plan for 2016: move to 6.04 branch

o Huge set of patches which will fix the private public definition to move to gcc5
