2022-11-24 Wouter Deconinck (PR#1012)
- DDG4: Geant4TCUserParticleHandler: Allow for asymmetric tracking region with tracker_region_zmin
2022-11-22 Markus Frank (PR#1023)
Take into account suggestions from PR #1021
2022-11-22 Markus Frank (PR#1021)
- Implemented issue #1010: Changing Geant4 physics flags
  o Extended the Geant4UIManager to support command queues at various stages of the program:
  -- configure
  -- initialize
  -- pre-run
  -- post-run
  -- terminate
  o Added interface function to directly communicate with the G4UI using string commands at any time
  from python.
  o Extended Geant4Kernel functionality to allow client actions to subscribe to stages of the program
  and perform dedicated actions on:
  -- configure
  -- initialize
  -- terminate
  As an example please see DDG4/src/Geant4UIManager.cpp
- Dropped issue #1004 after some tests and investigation:
  This issue cannot be resolved, because MC records may also be read without Geant4 and a physics list being initialized.
  Hence the event readers cannot implement such a feature if the event record does not support charge, but only the PDG code.
  Conclusion is to best update the charge of particles at the output stage using the PDG code or to implement an event action,
  which performs this actions right before the output stage.
- Simplified component properties.
- Improvements to DDDigi (work in progress)

Allow to set MeanExcEnergy, MeanEnergyPerIonPair and BirksConstant in G4Materials ionisation parameters.
Specify values in the compact description of the materials:

    <material name="Ice">
      <D type="density" value="1.0" unit="g/cm3"/>
      <composite n="2" ref="H"/>
      <composite n="1" ref="O"/>
      <constant name="BirksConstant"        value="123.456*mm/MeV"/>
      <constant name="MeanExcitationEnergy" value="79.7*eV"/>
      <constant name="MeanEnergyPerIonPair" value="50*eV"/>
    </material>

Units will be converted to Geant4 units in the converter.
See issue #890 for details.

If in DDG4 the the material debugging is enabled:

  # Configure G4 geometry setup
  seq, act = geant4.addDetectorConstruction("Geant4DetectorGeometryConstruction/ConstructGeo")
  act.DebugMaterials = True

this gives the following output:

On request from out LHC colleagues DD4hep supports channeling physics in Geant4.
To support channeling physics in Geant4 it is necessary to enable the transparent
creation of G4ExtendedMaterial and G4LogicalCrystalVolume instances.
This can be done in DD4hep with the supply of material and volume properties in DD4hep.

Material properties can be supplied in the compact description like here:
```
    <material name="Ice">
      <D type="density" value="1.0" unit="g/cm3"/>
      <composite n="2" ref="H"/>
      <composite n="1" ref="O"/>
      <constant name="Geant4-plugin:material"            option="ChannelingCrystalMaterial"/>
      <constant name="Geant4-ignore:crystal_data"        option="${DD4hepExamplesINSTALL}/examples/DDG4/data/Si220pl/Si220pl"/>
      <constant name="Geant4-ignore:crystal_orientation" option="(1,0,0)"/>
    </material>
```
The property starting with the tag Geant4-plugin is used to determine the proper plugin
preparing the G4ExtendedMaterial instance.
All properties with tags Geant4-ignore are not passed as material properties to Geant4.
Properties starting with this tag can be used by users to configure the G4ExtendedMaterial instance.

Volumes can as well have properties as this C++ example shows:
```
  Volume vol = Volume("Volume", solid, material);
  xml_elt_t ec = ...;
  vol.addProperty(ec.attr<std::string>(_U(name)), ec.attr<std::string>(_U(value)));
```
with values supplied by XML:
```
  <property name="Geant4-plugin" value="ChannelingCrystalVolume"/>
```
For more details see the example <DD4hep>/examples/DDG4/compact/Channeling.xml.
Again the property Geant4-plugin is used to call a plugin to create sub-classes
of G4LogicalVolume like G4LogicalCrystalVolume.

An example was prepared in <DD4hep>/examples/DDG4 containing:
- a compact description: compact/Channeling.xml
- an example factory for the G4ExtendedMaterial: src/ChannelingCrystalMaterial.cpp
- an example factory for the G4LogicalCrystalVolume: src/ChannelingCrystalVolume.cpp
- A script invoking Geant4 to test this setup: scripts/Channeling.py

- DDSim: restore the fixed momentum behaviour of --gun.energy, independent of the isotrop setting for the particle gun. If gun.energy is set, the momentum will have this value. If it is not set, momentumMin and momentumMax will be used to pick a value.

2022-07-19 Markus Frank (PR#933)
The fast simulation handling in Geant4 includes the GFlash interface
as implemented in <geant40-source>/source/parameterisations/gflash
and a fast simulation interface as provided by
<geant40-source>/source/processes/parameterisation

This MR allows to handle both mechanisms using the same callbacks
in the Geant4SensitiveActions using the callback specialization:
```
      /// GFLASH/FastSim interface: Method for generating hit(s) using the information of the fast simulation spot object.
      virtual bool processFastSim(const Geant4FastSimSpot* spot, G4TouchableHistory* history)  final;
```
in addition to the regular callback for full simulation:
```
      /// G4VSensitiveDetector interface: Method for generating hit(s) using the G4Step object.
      virtual bool process(const G4Step* step,G4TouchableHistory* history)  final;
```
The Geant4FastSimSpot is inspired by the G4GFlashSpot, but avoids the specialization towards GFlash
given that the G4FastHit and the G4GFlashEnergySpot are equivalent.
Together with the helper class Geant4FastSimHandler simple sensitive detector callbacks
can be implemented like:
```
    /// GFlash/FastSim interface: Method for generating hit(s) using the information of Geant4FastSimSpot object.
    template <> bool
    Geant4SensitiveAction<Geant4Tracker>::processFastSim(const Geant4FastSimSpot* spot,
							 G4TouchableHistory* /* hist */)
    {
      typedef Geant4Tracker::Hit Hit;
      Geant4FastSimHandler h(spot);
      Hit* hit = new Hit(h.trkID(), h.trkPdgID(), h.deposit(), h.track->GetGlobalTime());
      hit->cellID        = cellID(h.touchable(), h.avgPositionG4());
      hit->energyDeposit = h.deposit();
      hit->position      = h.avgPosition();
      hit->momentum      = h.momentum();
      hit->length        = 0e0;

Callbacks with this signature are called both for GFlash and the G4 fast simulation.

To simplify the user defined construction of fast simulation shower models
the helper class Geant4FastSimShowerModel is implemented as a Geant4Action
and hence allows to have options to be set by the user (including python).

As an illustration two fast simulation shower models were implemented in
<dd4hep>/DDG4/plugins/Geant4P1ShowerModel.cpp which were directly deduced
from the Geant4 example <geant4-source>/examples/extended/parameterisations/Par01.
Please see the source files for details.

To execute GFlash or fast simulation to simple python examples are provided
using simple silicon blocks as sensitive volumes:
- GFlash <dd4hep-dir>/examples/ClientTests/scripts/SiliconBlockGFlash.py
- Fast simulation <dd4hep-dir>/examples/ClientTests/scripts/SiliconBlockFastSim.py
To enable either the following actions are required:
1. Enable fast simulation for certain particles in the physics list:
```
  phys = geant4.setupPhysics('FTFP_BERT')
  ph = DDG4.PhysicsList(kernel, str('Geant4FastPhysics/FastPhysicsList'))
  ph.EnabledParticles = ['e+', 'e-']
  ph.enableUI()
  phys.adopt(ph)
```
This step is identical for GFlash and fast simulation physics.
2. Enable the shower mode:
```
  # Mandatory model parameters
  model.RegionName = 'SiRegion'
  model.Material = 'Silicon'
  model.ApplicableParticles = ['e+', 'e-']
  model.Etrigger = {'e+': 0.1 * GeV, 'e-': 0.1 * GeV}
  model.Enable = True
  model.enableUI()
```
Here the options must be set according to the parameters required by the shower models.

The G4 fast simulation interface is only functional for Geant4 version >= 10.07.
For lower versions of Geant4 missing classes are stubbed to allow the compilation.

First attempt to implement GFlash parametrization for DDG4

Example is in examples/ClientTests/scripts/SiliconBlockGFlash.py
Relevant code changes are for the detector construction:

seq, act = geant4.addDetectorConstruction('Geant4DetectorGeometryConstruction/ConstructGeo')
....
# Enable GFlash shower model
model = DDG4.DetectorConstruction(kernel, str('Geant4GFlashShowerModel/ShowerModel'))
model.Parametrization = 'GFlashHomoShowerParameterisation'
# Mandatory model parameters
model.RegionName = 'SiRegion'
model.Material = 'Silicon'
model.Enable = True
# Energy boundaries are optional
model.Emin  = {'e+': 0.1*GeV, 'e-': 0.1*GeV }  # Units in GeV
model.Ekill = {'e+': 0.1*MeV, 'e-': 0.1*MeV }
model.enableUI()
seq.adopt(model)

and the physics list.

# Now build the physics list:
phys = geant4.setupPhysics('FTFP_BERT')
ph = DDG4.PhysicsList(kernel, str('Geant4FastPhysics/FastPhysicsList'))
ph.EnabledParticles = ['e+', 'e-']
ph.BeVerbose = True
ph.enableUI()
phys.adopt(ph)

The setup of the regions is crucial for GFlash to work, because it applies to regions.
For concrete detector constructors the proper regional setting are mandatory, but do not affect
this implementation.

Easy possibility to store condition payloads as std::any.
- Use of specialized handle class dd4hep::ConditionAny to support the functionality.
  The payload is automatically bound to an object of type std::any.
  Example code of constructor and how to access data:
```
/// Emplacement construction
std::vector<int> value;
... // fill data
ConditionAny c2("name", "type", std::move(value));

/// Construct conditions object with empty std::any	 
ConditionAny c2("name", "type");
/// Assign data (empty vector<int>) to the payload:
c2.get() = vector<int>();

/// Access data:
vector<int>& data = c2.as<vector<int> >();
```
  as a corollary to this approach these conditions can only be stored and retrieved from ROOT storage
  if the requirement for ROOT are satisfied. Otherwise no other restrictions are imposed.
  The corresponding grammar instance is part of the library.
- Add example to illustrate the functionality in example/conditions:
  o examples/Conditions/src/ConditionAnyExampleObjects.cpp
  o examples/Conditions/src/ConditionAnyExampleObjects.h
  o plugin: examples/Conditions/src/ConditionAnyExample_populate.cpp
  Invocation:
```
   $> geoPluginRun  -destroy -plugin DD4hep_ConditionAnyExample_populate \
        -input ../../DD4hep/examples/AlignDet/compact/Telescope.xml -iovs 1
```
- Plugin example to test basic functionality and verify proper assignment works
  o examples/Conditions/src/Conditions_any_basic.cpp
  Invocation:
```
$> geoPluginRun -destroy -volmgr -plugin DD4hep_Conditions_any_basic
```

See for the example
-- /examples/ClientTests/src/MaterialTester_geo.cpp
-- /examples/OpticalSurfaces/compact/ReadMaterialProperties.xml
-- /examples/OpticalSurfaces/scripts/ReadMaterialProperties.py

The python file is only there to show that the G4 simulation does not get screwed.....
Otherwise: to define properties, which do not participate in Geant4:

    <material name="Water">
      <D type="density" value="1.0" unit="g/cm3"/>
      <composite n="2" ref="H"/>
      <composite n="1" ref="O"/>
      <!-- Properties used by Geant4    -->
      <property name="RINDEX"        ref="RINDEX__0x123aff00"/>
      <property name="ABSLENGTH"     ref="ABSLENGTH__0x123aff00"/>
      <property name="FASTCOMPONENT" ref="FASTCOMPONENT__0x123aff00"/>
      <property name="SLOWCOMPONENT" ref="SLOWCOMPONENT__0x123aff00"/>
      <!-- Properties ignored by Geant4 -->
      <property name="Property_of_mine" ref="Water__0x123aff00"/>
      <constant name="BirksConstant"    ref="Birk__Water|Geant4-ignore"/>
      <!-- Constants  ignored by Geant4 -->
      <constant name="Constant_of_mine" ref="Water__Mine|Geant4-ignore"/>
    </material>

where:

  <properties>
    <constant name="Birk__Water|Geant4-ignore" value="12.345678"/>
    <constant name="Water__Mine|Geant4-ignore" value="87.654321"/>
  </properties>

and

    <matrix name= "Water__0x123aff00" option="Geant4-ignore" coldim="1" values="  
              2.034*eV 
              2.068*eV 
              2.103*eV 
              2.139*eV 
              2.177*eV 
              2.216*eV 
    "/>
  </properties>

For non-const properties you have to set the option to "Geant4-ignore",
otherwise you append the string to the name. The "ref" string in the material
and the property must match.
In the program you can then access the propertiers by name like this:

Material material(...)
double v = material->GetConstProperty("BirksConstant");
TGDMLMatrix* m = material->GetProperty("Property_of_mine");

like any other property. See for details:

- Rework the EDM4hep output action. The major reason is the renaming of the default types in AIDASoft/podio#205 and its effects on EDM4hep (key4hep/EDM4hep#132). These changes are:

  - Switch to range-based for-loops where possible
  - Keep an internal map of the collections to get rid of the const_casts that were used before.
- EDM4hep output: Make sure that the daughter relations are also set, because that is not done automatically in EDM4hep but is in LCIO.

Support for multiple readouts or (G4VUserParallelWorld equivalent)
Issue #861
Example:
examples/CLICSiD/compact/SiD_ECAL_Parallel_Readout.xml +
examples/CLICSiD/scripts/SiD_ECAL_Parallel_Readout.py

For a given subdetector the sequence of sensitive actions can be enhanced
having multiple sensitive actions where each one can have its own Readout
definition. Hence each action can produce its own set of hits depending on the
readout geometry (segmentation).
in XML these readout structures must first be defined:

  <readouts>
    <readout name="EcalBarrelHits">
      <segmentation type="CartesianGridXY" grid_size_x="3.5" grid_size_y="3.5" />
      <id>system:8,barrel:3,module:4,layer:6,slice:5,x:32:-16,y:-16</id>
    </readout>        

    <readout name="EcalBarrelHits_0">
      <segmentation type="CartesianGridXY" grid_size_x="1" grid_size_y="1" />
      <id>system:8,barrel:3,module:4,layer:6,slice:5,x:32:-16,y:-16</id>
    </readout>        
 ....
  </readouts>

and can then be assigned to the sensitive actions in the python setup:

  typ = sid.geant4.sensitive_types['calorimeter']
  seq = DDG4.SensitiveSequence(sid.kernel, str('Geant4SensDetActionSequence/') + det)
  seq.enableUI()
  act = DDG4.SensitiveAction(sid.kernel, str(typ + '/EcalBarrelHandler'), det)
  act.enableUI()
  seq.add(act)
  # Add extra parallel readout action with readout EcalBarrelHits_0
  act = DDG4.SensitiveAction(sid.kernel, str(typ + '/EcalBarrelHandler_0'), det)
  act.ReadoutName = 'EcalBarrelHits_0'
  act.enableUI()
  seq.add(act)
  # Add extra parallel readout action with readout EcalBarrelHits_1
  act = DDG4.SensitiveAction(sid.kernel, str(typ + '/EcalBarrelHandler_1'), det)
  act.ReadoutName = 'EcalBarrelHits_1'
