  1. Code Migration James N. Bellinger University of Wisconsin at Madison 18 August 2010 18 August 2010 1

  2. Summary • No major problems • Continuing series of non-.m release questions • Problem committing to online cvs, seems to be solved • But, uninitialized variables are showing up! • Test of fixing warnings in a library • Glitches: perl_dbd_oracle has oracle_client 9 references built in • Still have 13% of libraries with no responsible party • How do we deal with/flag obsolete cvs libraries? 18 August 2010 2

  3. Uninitialized memory • Uninitialized memory in MuonCalorCalculator.cc was causing jobs to crash—fixed. • Still tracing a problem in CosmicsMods • Lynn suggested using -Wuninitialized -O2 • Ed Rogers found 115 such in BottomMods • I found 51 in Muon • I attempted to fix all the warnings in Muon: • It is not automate-able and it took over 2 hours • Many are trivial, most are from libraries it depends on • Over 300 libraries... 16 August 2010 3

  4. Outstanding Issues Include • Crash in CosmicMods • Still investigating • perl_dbd_oracle has oracle_client 9 references in it • Need a different version? • “boost” package version questions • “uint” usage Fixed last night 16 August 2010 4

  5. Library Maintenance • Of main 302 libraries, 40 do not yet have a (semi) active CDF member who has replied that they are still associated with it • BaBar looks trivial, Panic is empty • Electron, ElectronMods, ElectronObjects have nobody left on the list at all in CDF • Others just have no answers yet. 16 August 2010 5

UtilPatterns jbk stager lammel Some of these I know are here; I just haven't gotten a formal reply. 16 August 2010 6

  7. Obsolete Libraries • Homer Wolfe expressed an interest in getting rid of some obsolete cvs directories. • I think code should be treated like data and like our logbooks—never deleted, though we can flag it as useless • Proposal: • Add a file AAAOBSOLETE containing a description of whodunit and what it was for and when • Empty the allowed file in that directory of check_access.d • Scripts ignore directory trees with AAAOBSOLETE 16 August 2010 7
