Merged PRs

Closed PRs, closed issues and fixed problems


Pending Problems


  • ISSUE1285:  Memory Consumption of Sensitive Detectors
                          ==> Should be handled as illustrated in PR1288. Intrinsic problem of the Geant4VolumeManager;
  • ISSUE1297:  Possible to dump all available readout elements?
                          ==> Possibly a copy of unsolved ISSUE580 from Valentin about enumerating all sensitive cells.
  • ISSUE1319:  Problem with regexSensitiveDetector and volume IDs
                          ==> Interesting use case for reg-ex sensitive detectors
                                 having a VolumeMgr equivalent.
  • ISSUE1320:  Replacing a Handle<Segmentation> which contains a MultiSegmentation with the underlying Segmentation
                          ==> Unclear what he really means.
  • ISSUE1335:   Uniform random picking of points on detector surfaces for noise studies
                           This problem is linked to #1297 and #580.

  • ISSUE1373:  Add GeneratorInfo to EDM4hepReader (Andre)
  • ISSUE1443:  Make user particle handler extensible
                           ---> Maybe we should take advantage and re-collect requirements.
  • ISSUE1458: XML file vs TGeoStored geometry in GenFit


  • New issues:
  • ISSUE1469: Memory leak in Compact2Objects / Detector concerning Headerbug
  •
