  1. PyCool on ROOT6 status report Andrea Valassi (IT-SDC) Thanks to Axel, Benedikt, Danilo,Fons, Marco, Philippe, Wim…! ROOT6 planning meeting Wednesday 20thNovember 2013

  2. Progress this week (since Wed 13th) • Fixed: no more “JIT does not support inline ASM” • Rebuilt Boost with one more patch identified using strace • Reviewed status of all PyCool tests after applying this fix • Removed old pending issues, added new ones • New: unresolved template parameters • Fixed: CMT config to compile PyCool dict with c++11 • Fixed: PyCool vector payload issues with ROOT6 • Fixed in ROOT: methods within nested namespaces • Clarified: header lookup path for JIT

  3. Summary of pending issues • Blocker: JIT does not support inline ASM (bug #102771) • Workaround (new Boost) crashes in LHCb (ROOT-5623, ROOT-5699) • Blocker: unresolved template parameters (ROOT-5711) • Blocker: crashes and glibc memory corruptions (ROOT-5643) • High: typedef’d constants in namespace (ROOT-5658?) • High: problem with isinstance (ROOT-5718) • High: c++ exception propagation to Python (ROOT-5603) • Medium: assertions if LLVMDEV is enabled (ROOT-5697) • Low: why ROOT_INCLUDE_PATH in LCGCMT? (ROOT-5623)

  4. Testing PyCool on the “test” slot • Two differences in “test” with respect to “dev2”: • 1. Use ASM-free Boost in “test”: needed by PyCool • Otherwise “JIT does not support inline ASM” errors • Use standard Boost in “dev2”: ASM-free Boost crashes in LHCb • 2. Use ROOT_INCLUDE_PATH unset in “test”: why? • Days ago I thought this should be set for PyCool, now not sure • Not clear to me at this point which setting is better for PyCool… • A third difference was removed on Monday • 3. Use LLVMDEV disabledin “test”: needed by PyCool • Otherwise get a “Tok assertion” that still needs to be debugged • LLVMDEV was enabled in “dev2” instead, but it is now disabled too
