AIDASoft/DD4hep: v01-04

2017-10-17 Markus Frank (PR#248) ### 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.

• Fix C++11 pointer error by adding include <memory> for 'unique_ptr' (GCC 4.9).

2017-10-13 Marko Petric (PR#246) ### 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.

• Added helper function getAttrOrDefault (defined in DDCore/include/XML/Helper.h) This function getAttrOrDefault(xml::Element e, xml::XmlChar attr_name, T default_value) will return the attribute name, converted to to type T but if it is not found it will return default_value. When building new detectors supplying this is useful for supplying default attribute values.

2017-10-19 Markus Frank (PR#249)

• Improve the CMS tracker visualisation
• Add DDG4 simulation example to DDCMS
• Add some plugins to add visualisation attributes if required (not for the compact description)

• DDG4/python/DDG4.py: loadDDG4() changed to not raise exception if libraries are already loaded

• Added requirement of Python 2 in cmake/FindPYTHON.cmake. This makes clear the requirement of Python 2, and resolves the issue where CMake tries to build with Python 3 in a system where both exist.

2017-11-07 Frank Gaede (PR#256)

• bug fix in BitField64::operator[std::string]()
• make uses of TString in DocumentHandler.cpp compatible with clang9 (on Mac)
