ROOT Planning Meeting

Present: The ROOT Team, Marco, Benedikt, Andrea, Valeri (R), Bill (R)

o Pere about the slides of Axel - Delayed symbols: Why can't we have rootmaps?
  - Philippe: it might not be a general solution. In case for example one has the same symbol in n libraries.

o Valeri:
  - Could not inject changes in root in the Atlas builds yet: the build was broken for other reasons. Will do that today.
  - Probably reduce committment to ROOT6 because of duties in the visualisation area.

o Marco
  - Exception specification problem: tests do not fail, but there is a printout more wrt the ref. Workaround might be
    tried, no time to do that yet.
  - TF1 integration: the new precision did not solve this. The developers will try to use the cdf and marco may try to
    further debug.
  - Infinite loop when trying to use a map<string,string> triggers an infinite loop in PyRoot.
  - Hard to say more w/o solving these 3 issues.
  - Will report a performance issue to see if this is header parsing, PyROOT or something else.

o Bill
  - Callfunc table issue solved for the conditions, but more encountered.
  - Speed issue: the load of libs are still slow (minutes).

o Andrea
  - Report about current issues: see slides.
  - News: go for the interpreter only dictionary with empty selection file and explicit load of libPyCool.
There are minutes attached to this event. Show them.
