        • in this current process, also allow the same following treatments for the new hit.
  • 2018-06-21 Markus Frank (PR#409)

    • Support out-of-source builds of DD4hep examples.
      Comes with an expense: A new environment DD4hepExamplesINSTALL.

    • Fix truncated tube shape
  • 2018-06-04 Markus Frank (PR#400)

    • Allow for world volumes other than boxes. See examples/ClientTests/compact/WorldVolume.xml how to set it up. The effective thing is that the top level volume must be set to the TGeoManager before Detector::init(). If a top level volume is set, it is implicitly assumed to be the world volume. Otherwise the already existing mechanism (box volume) is activated.
    • Add new basic shape tests.
  • 2018-06-01 Markus Frank (PR#399)

    • As discussed in issue #398 The use of TGeoUnits is inconvenient. The dd4hep units are now exposed in the python modules.
    • Basic shapes are now tested in the regular ctest executions. The mesh vertices of the shapes were
      saved to a reference file and are compared to in subsequent runs. The reference files reside in
      examples/ClienTests/ref. See examples/ClientTests/compact/Check_Shape_*.xml for details.
    • The ROOT UI and some dump plugins were enhanced to expose more information.
  • 2018-05-30 Markus Frank (PR#397)

    • Enable to start DDG4 using a saved detector description in a ROOT file.
      • Added corresponding test: Persist_CLICSiD_Geant4_LONGTEST
    • Fix shape constructors for Trap and PseudoTrap
    • The python module DD4hep.py is gone as discussed in the developers meeting use dd4hep.py instead.
      • on masOS : your "git pull" possibly deletes both files. you may have to checkout dd4hep.py again, due to fact that the filesystem is case-insensitive.

    Implementation of non-cylindrical tracking region (resolves #371)

    • It is possible to define volumes in a parallel world such as e.g. a tracking region. In principle any volume hierarchy may be attached to the parallel world. None of these volumes participate in the tracking as long as the "connected" attribute is set to false. The hierarchy of parallel world volumes can be accessed from the main detector object using
      dd4hep::Volume parallel = dd4hep::Description::parallelWorldVolume()

    This parallel world volume is created when the geometry is opened together (and with the same dimensions) as the world volume itself.

    • IF the NAME of the volumes is "tracking_volume" within the compact notation it is declared as the Detector's trackingVolume entity and is accessible as well:
      dd4hep::Volume trackers = dd4hep::Description::trackingVolume()
    • Although the concept is available in the DD4hep core, it's configuration from XML is only implemented for the compact notation. For details see the example examples/ClientTests/compact/TrackingRegion.xml.
    • If the volume should be connected to the world: connected="true". This is useful for debugging because the volume can be visualized else if the volume is part of the parallelworld: connected="false". The volume is always connected to the top level. The anchor detector element defines the base transformation to place the volume within the (parallel) world.
         <parallelworld_volume name="tracking_volume" anchor="/world" material="Air" connected="true" vis="VisibleBlue">

    Enhancement of assemblies, regions and production cuts (resolves #373)

    On request from FCC particle specific production cuts may be specified in the compact notation. These production cuts (Geant4 currently supports these for e+, e-, gammas and protons) are specified as "cut" entities in the limitset. (See the example examples/ClientTests/compact/Assemblies.xml).

    • The hierarchy of cuts being applied is:
      • If present particle specific production cuts for a region are applied.
      • else the "cut" attribute of the compact region specification is used
      • else the global Geant4 cut is automaticallly applied by Geant4.

          <!--
               These are particle specific limits applied to the region

    SensitiveDetector types not changed by Geant4SensDetActionSequence (resolves #378)

    The sensitive detector type defined in the detector constructors is no longer changed intransparently in the back of the users. This may have side-effects for creative detector constructor writers, who invent sd types out of the sky. These obviously will not work with Geant4, because in Geant4 a mapping of these types must be applied to supported sensitive detectors. Now the mapping of a sd type (e.g. "tracker") is strict in the python setup. The default factory to create any sensitive detector instance in Geant4 (ie. an object of type G4VSensitiveDetector, G4VSDFilter, Geant4ActionSD) is a property of the Geant4Kernel instance and defaults to:

     declareProperty("DefaultSensitiveType", m_dfltSensitiveDetectorType = "Geant4SensDet");
    • Since the actual behavior is defined in the sequencer instanciated therein this default should be sufficient for 99.99 % of all cases. Otherwise the factory named "Geant4SensDet" may be overloaded.
  • 2018-05-15 David Blyth (PR#379)

    • Geant4FieldTrackingConstruction now properly overrides constructField()
  • 2018-05-03 David Blyth (PR#377)

    • Geant4Handle unhandled reference to shared actions. This affected the destruction of shared actions.
  • 2018-05-03 Markus Frank (PR#375)

    • Development of a small user example on how to do analysis in DDG4.

      • See examples/DDG4/src/HitTupleAction.cpp
      • Simply collect the energy deposits of hits and write an N-tuple with them.
      • The example shows how to access the hit collections and to extract the data in order to write other more sophisticated analyses.
    • This DDG4 action is used in one of the Minitel examples: examples/ClientTests/srcipts/MiniTelEnergyDeposits.py

  • 2018-05-02 Markus Frank (PR#374)

    • recommission the multithreaded SiD example
      • DDG4/examples/SiDSim_MT.py vs. DDG4/examples/SiDSim.py
  • 2018-04-19 Markus Frank (PR#370)

    • Allow to disable building the documentation cmake option BUILD_DOCS. By default ON and backwards compatible. If set to OFF no doc shall be built. (not everybody has biber installed)
    • Move from DD4hep.py to dd4hep.py, since DD4hep.py has to disappear due to conflicts on MAC.
  • 2018-04-13 Markus Frank (PR#367)

    • resolves #361
      The Detector object has a state Detector::state() with three values:

        /// The detector description states
        enum State   {
          /// The detector description object is freshly created. No geometry nothing.
          NOT_READY = 1<<0,
          /// The geometry is being created and loaded. (parsing ongoing)
          LOADING   = 1<<1,
          /// The geometry is loaded.
          READY     = 1<<2
        };

      It starts with NOT_READY, moves to LOADING once the geometry is opened and goes to READY once the geometry is closed. As suggested in the developers meeting: the initial field object is invalid and gets created only once the geometry is opened. As a corollary, the field may not be accessed before. Geometry parsers must take this behavior into account!

    • Address some compiler warnings.

      • Mainly add override/final statements in header files.
    • Implement a module to invoke python as a DD4hep plugin:
      invoked e.g. by: geoPluginRun -plugin DD4hep_Python -dd4hep -prompt

      geoPluginRun -plugin DD4hep_Python -help
      Usage: -plugin <name> -arg [-arg]                                                  
         name:   factory name     DD4hep_Python                                        
         -import  <string>        import a python module, making its classes available.
         -macro   <string>        load a python script as if it were a macro.          
         -exec    <string>        execute a python statement (e.g. import ROOT.    
         -eval    <string>        evaluate a python expression (e.g. 1+1)          
         -prompt                  enter an interactive python session (exit with ^D)   
         -dd4hep                  Equivalent to -exec "import dd4hep"                
         -help                    Show this online help message.                       
      
         Note: entries can be given multiple times and are executed in exactly the     
               order specified at the command line!                      
      

      Implementation wise the plugin is a simple CLI wrapper for TPython.

    • DDCore: Add interface to allow URI blocking during file parsing. Default is as now.
    • DDCMS: Add conversion of new shapes.
  • 2018-04-10 Markus Frank (PR#359)

    • Bunch of fixes. Mostly in examples/DDDB
    • Only build examples/DDDB if XercesC is present.
    • Only build examples/DDCMS if CLHEP is present
  • 2018-04-09 Markus Frank (PR#357)

    • Add configuration options for loading DDDB
  • 2018-04-05 Markus Frank (PR#351)

    • To avoid unwanted disappearing conditions sub pools, a conditions slice may be instructed to collect shared references to the used pools in the slice.
    • For python:
      • Move DDG4/SystemOfUnits.py to DDG4/g4units.py
        Keep SystemOfUnits.py with deprecation warning
      • move DD4hep.py to dd4hep.py.
        import dd4hep also imports all TGeoUnit units into its namespace.
        Hence: import dd4hep; print dd4hep.m gives: "100.0"
      • DD4hep.py is kept for backwards compatibility issuing a deprecation warning
      • DDG4.py: imports g4units as G4Units: DDG4.G4Units.m etc.
      • DDG4.py: imports TGeoUnit as TGeo4Units: DDG4.TGeoUnits.m etc.
      • Some problem with replacing DD4hepUnits.h with TGeoSystemOfUnits.h
        Surface test complains. To be investigated. Keep old DD4hepUnits for the time being.
  • 2018-04-05 Markus Frank (PR#350)

    • Merge DDCMS and DDCMSTests to DDCMS
    • Move DDDB to the examples/
    • Add tests DDDB_DeVelo and DDDB_DeVelo_Gaudi missing from #349
  • 2018-04-05 Markus Frank (PR#349)

    • Resolves #339
    • DDDB conditions had a bug when loading from file base. The IOV was not handled properly. Now the resulting IOV is configurable using properties.
    • Added Gaudi like example use case for options handling with the DeVelo detector elements.
    • Configuration improvement in DDG4 action Output2ROOT:
      • New property "DisableParticles" allows to suppress the MCParticle record from being written to the ROOT file.
      • dto. the option "DisabledCollections" allows to NOT write any hit collection.
      • Unit tests for these options are not (yet) present.
    • DDCond: allow for user defined conditions cleanup policies. Base class dd4hep::cond::ConditionsCleanup. Callbacks are issued to the class for IOV type pools and IOV dependent pools asking if the pools should be processed.
  • 2018-04-05 Marko Petric (PR#344)

    • Move DDCMS into examples as it is not core functionality

    DDG4 enhancements

    • Enable framework support in DDG4. The Geant4Context is the main thread specific accessor to the dd4hep, DDG4 and the user framework.

      • The access to the dd4hep objects is via the Geant4Context::detectorDescription() call,
      • the access to DDG4 as a whole is supported via Geant4Context::kernel() and
      • the access to the user gframework using a specialized implementation of:
        template <typename T> T& userFramework() const;

      A user defined implementations must be specialized somewhere in a compilation unit of the user framework, not in a header file. The framework object could host e.g. references for histogramming, logging, data access etc.

      This way any experiment/user related data processing framework can exhibit it's essential tools to DDG4 actions.

      A possible specialized implementations would look like the following:

        struct Gaudi  {
          IMessageSvc*   msg;
          IHistogramSvc* histos;
          ....
        };
        template<> Gaudi& Geant4Context::userFramework<Gaudi>()  const  {
          UserFramework& fw = m_kernel->userFramework();
          if ( fw.first && &typeid(T) == fw.second ) return *(T*)fw.first;
          throw std::runtime_error("No user specified framework context present!");
        }

      To access the user framework then use the following call:

      Gaudi* fw = context->userFramework<Gaudi>();

      of course after having initialized it:

        Gaudi * fw = ...;
        GaudiKernel& kernel = ...;
        kernel.setUserFramework(fw);
    • G4RunManager is now a plugin. To enable user defined run managers in DDG4, the run manager is encapsulated in a Geant4Action. See DDG4/plugins/Geant4RunManagers.cpp how to implement such plugins. Currently there are to factories implemented:

      • G4RunManager -> factory invokes the single threaded G4RunManager
      • G4MTRunManager -> factory invokes the multi threaded G4MTRunManager

      The factory names here are identical to the names of the native G4 classes.

    VolumeManager Implementation

    A possibly important bug was fixed for the lookup of top level subdetectors in the VolumeManager by volume identifers of (sensitive) volumes. Due to a bug in the de-masking possible wrong top level subdetectors were returned. The default use cases typically do not use this call and hence should not be affected.

    DDCMS:

    • Improve the CMS excercise. New examples etc.
    • Support for simulation using DDG4 (at least partially - since not all subdetector volumes are accepted by Geant4).

    DDG4:

    • Event reader returns EVENT_READER_EOF if EOF is detected rather than a generic IO error.
    • Add generator status word to the Geant4Particle object. Remove the extension mechanism, which is very heavy to just add one integer.

    General:

    • We need to distinguish the plugins using some namespace mechanism. I started to introduce the namespace separator "_". Hence all DD4hep plugins start with DD4hep_<plugin>. I hope this does not break everything. If it does, please notify me and we can undo.

    Implement ROOT persistency mechanism for detector descriptions (continuation of #202).

    Object extensions are now persistent.

    This is however not for free: it requires a dictionary for the extension itself and it requires a dictionary for the class holding the extension. These are:

    • dd4hep::DetElement::DetElementExtension<IFACE,CONCRETE> for DetElement extensions.
    • dd4hep::SimpleExtension<IFACE,CONCRETE> for simple extension managed by the user framework (user calls explicitly destructor).
    • dd4hep::DeleteExtension<IFACE,CONCRETE> for simple extension managed by dd4hep (dd4hep calls automatically destructor on hosting object destruction).
    • dd4hep::CopyDeleteExtension<IFACE,CONCRETE>. As above, but these extensions support calling the copy constructor of the embedded object and hence allow to copy also the hosting objects.

    Please note: to persistify these objects it was necessary to no longer use the type-info of the objects as an identifier, but rather a 64-bit-hash of the raw type-info-name. This relies that this name is identical across platforms. This typically is true for linux, but not enforced by any standard.

  • 2017-08-11 Andre Sailer (PR#213)

    • CMake:: dd4hep_generate_rootmap: use CMAKE_INSTALL_LIBDIR if it is set. If the macro is called from other libraries this variable might be set and should be used for consistency. Fixes #212
  • 2017-07-13 Markus Frank (PR#202)

    Implement ROOT persistency mechanism for detector descriptions

    The following commits allow to save and restore Detector objects (ie. the full detector description) to/from ROOT. Most changes affected the usage of void pointers.

    It is NOT possible to:

    • save object extensions. Another usage of void pointers and type-info objects, which both cannot be saved.
    • save callback objects. Callbacks store in memory pointers to member functions. These depend on the loading of libraries at run-time and hence may differ from application to application.
    • save conditions slices. This shall be a futute extension. There should be no fundamental problem doing so - it was simply not yet done.

    In the example area a new slot call "Persistency" was created with various tests:

    • Save and restore simple conditions
    • Save and restore the MiniTel detector (examples/ClientTests/compact/MiniTel.xml)
    • Save and restore the CLICSiD detector (examples/CLICSiD/compact/compact.xml)

    The detector examples also have a set of tests associated to check the validity of the restored information.

    Integrate DDSegmentatation into DDCore

    As a first step to start the cleanup of DDSegmentation the code was integrated into DDCore. For backwards compatibility a dummy library libDDSegmentation.so is kept, so that client cmake files directly referring DDSegmentation still work. This tough is only a temporary measure and users should remove references to the DDSegmentation library. Include files can be accessed as before. These are part of the DDCore include directory.

  • 2017-08-15 Yorgos Voutsinas (PR#216)

    • Adding variable "nocore" for beam pipe (with default value = false) In case the variable appears in the BP xml file as "true", the BP sections will have no core of beam material, in order that someone might add various BP walls made of different materials while avoiding G4 overlaps. Example of use:
    <detector name="BeBeampipe" type="DD4hep_Beampipe_o1_v01" insideTrackingVolume="true" nocore="true" vis="BeamPipeVis">

    Enhance ROOT Detector Description Persistency

    Conditions slices from the DD4hep conditions store can now be saved to ROOT files ans named objects. Conditions persistency examples are added to the examples/Conditions section.
    The examples are derived from the Telescope and CLICSiD example:

    • Conditions_Telescope_root_save
    • Conditions_Telescope_root_load_iov
    • Conditions_Telescope_root_load_pool
    • Conditions_CLICSiD_root_save_LONGTEST
    • Conditions_CLICSiD_root_load_iov_LONGTEST
    • Conditions_CLICSiD_root_load_usr_LONGTEST
    • Conditions_CLICSiD_root_load_cond_LONGTEST

    Fix Handle Problem when Accessing Materials from Volumes

    A cast problem was not spotted in the last commit, which manifested itself in accessing invalid materials from volumes. This commit resolves #211 , reported by @jhrdinka.

    A set of tests checks this behaviour in the ClientTests: ClientTests_volume_materials_<text>, where the volume tree is scanned and for all sensitive volumes and access the corresponding materials/TGeoMedium entities from the volume object.

    Implement ROOT persistency mechanism for the conditions

    Conditions pools can now be made persistent provided all the dictionaries for the payload objects are provided. A new class ConditionsRootPersistency allows to save and re-load conditions pools to/from a ROOT file. Such pools can either be:

    • Simple ConditionsPool objects
    • The entire IOV indexed pool set (class ConditionsIOVPool) or
    • A the pool used by a ConditionsSlice (class UserPool).
    • A std::vector which belong all to the same IOV

    In any case the restoration of the saved conditions is performed through the ConditionsManager interface in order to ensure proper management of the added condition objects.

    Some example plugin tasks were added in examples/Conditions:

    • DD4hep_ConditionExample_save to save conditions to a ROOT file.
    • DD4hep_ConditionExample_load to restore conditions from file.

    Others to come.

    Split of dictionary files

    The ROOT dictionary creation in DDCore was getting increasingly large. Now the ROOT dictionaries are created in several files, what firstly allows them to be produced in parallel and secondly eases the compilation due to smaller generated file sizes.
