Present: A.Sailer, M.Frank, T.Madlehner
Link to minutes of previous meeting
1) ISSUE1199: Persist hepmc vertex status code into output
==> Should we eliminate Geant4EventReaderHepMC
==> Decision: Geant4EventReaderHepMC will be removed
2) ISSUE1285: Memory Consumption of Sensitive Detectors
==> Should be handled as illustrated in PR1288. Intrinsic problem of the Geant4VolumeManager;
3) ISSUE1296: DetectorImp::endDocument() called twice for some geometries?
==> Unsure if it is a problem wrongly configuring multiple xml inputs.
4) ISSUE1297: Possible to dump all available readout elements?
==> Possibly a copy of unsolved ISSUE580 from Valentin about enumerating all sensitive cells.
5) ISSUE1305: Get proper hit/MCParticle relations from Geant4Output2EDM4hep
==> Bit misleading: hits are sometimes not attached to output particle.
==> Problem od Geant4UserParticleHandler ?
1) PR1286 Fix a few compiler warnings (Juan Carceller)
2) PR1287 Update to global alignment: Fix global alignment for assemblies (Markus)
==> reported by Ben, required ROOT HEAD
3) PR1288, ISSUE1285: Geant4 sensitive assignment action depending on regex rather
than brute force Geant4VolumeManager (Markus)
==> Do not enforce volumes entering the Geant4VolumeManager (Memory issue)
==> Assign sensitive detectors based on regular expressions when scann volume trees
==> Example BoxOfStraws
4) PR1289: See https://github.com/AIDASoft/DD4hep/pull/1288 Add example for illustration (Markus)
==>Addendum to PR 1288:
==>Add Geant4Action printing resource consumption during detector construction
5) PR1290: Fix compiling with Clang 18 and a few warnings (Juan Carceller)
6) PR1293 superseded by PR1301: Revert change from #1288 (Juan Carceller, Markus)
==> Revert change in DDG4.py causing problems in Key4hep nightly builds.
7) PR1299: CI: use alma9 stack for pylint check (Andre)
8) PR1298, ISSUE1291: Improve lookup speed of GeoHandler (Sang Yun Ko)
9) PR1294: Adding CylindricalGridPhiZ files (Yan Bedfer)
==> Added new segmentation.
10) PR1303: Add Geant4TVUserParticleHandler (Leonhard Reichenbach)
==> Allow for arbitrary tracking volumes in DDG4 rather than only the standard cylinder.
Andre: Nothing else than described above. A new tag supposedly will come soon.
Markus: NTR. Issue 1305 will have to be treated.
Thomas: NTR
