Geant4 7.1 - patch-01 Release Notes
-----------------------------------
25 October 2005
List of fixes included in this public patch since the public release 7.1:
o Configuration:
-------------
+ Excluded usage of unnecessary 'ranlib' at creation of the libraries
for WIN32-VC system. Fixes an observed problem of debug-symbols
corruption.
+ Synchronized CXXFLAGS warning options of WIN32-g++ with Linux-g++.
+ Fixed Configure script for --incflags and --ldflags options.
o Event:
-----
+ Corrected typo in printout in G4GeneralParticleMessenger.
Addresses problem report #786.
o Geometry:
--------
+ navigation
o G4DrawVoxels: removed unnecessary 'panic' message in
ComputeVoxelPolyhedra() and some code cleanup.
+ solids/BREPS
o Fixed problem of double-deletion in G4BREPSolidPolyhedra and
G4BREPSolidPCone destructors.
+ solids/CSG
o Fixed bug in G4Sphere::DistanceToOut(p,v): added check for
intersection with double cone.
o Fixed bug in G4Para::DistanceToOut(p,v) for the case v.x()<0.
Following problem report from user posted on Hypernews (#452).
o Improved implementation for DistanceToIn/Out() in G4Torus to make use
of G4JTPolynomialSolver for precise calculation of the intersections.
+ solids/specific:
o Fixed compilation warning on WIN32-VC for G4VSurface.cc.
o Global:
------
+ G4Allocator: initialise esplicitely data in copy-ctor.
+ G4AllocatorPool: added default dummy argument to ctor to allow for
default-ctor
o Parameterisations:
-----------------
+ Added overflow protection in method GenerateRadius() for
GFlashHomoShowerParamterisation in the 'gflash' module.
o Particles:
---------
+ Fix to prohibit creation of ions in 'PreInit' state to make sure
that proper processes will be attached to the ions.
o Electromagnetic processes:
-------------------------
+ high-energy:
o Fix a misprint in G4BetheBlochNoDeltaModel and minor cleanup.
+ muons:
o In all energy loss models return protection against the case
tmin>tmax (fixes bug report).
o Fix angular distributions of secondaries and 4-momentum balance
in G4MuBremsstrahlungModel and G4MuPairProductionModel.
o Added protection in G4MuPairProductionModel needed for sampling
of pair energy in the case of low cuts.
+ standard:
o In all energy loss models return protection against the case
tmin>tmax (fixes bug report).
o Fix for initialisation of G4eBremsstrahlungModel.
o Fix a bug in calculation of chemical correction in G4BraggIonModel
and fix in G4BraggModel for problem observed when increasing
precision using standard model and chemical effect.
+ utils:
o G4VEnergyLossProcess: return number protections against numerical
imprecision, which were used in version 7.0 and removed in 7.1
(fixes bug report)
o Set default lambdaFactor to 0.8 for integral mode (improvement in
CPU performance for low cuts).
o G4VEmProcess: use integral mode only for charged particles.
o G4EmModelManager: fix a cut calculation for the e+e- pair
production physics process.
o G4VMultipleScattering: fixed error in a protection in
GetContinuousStepLimit().
+ xrays:
o Changed variable name 'MeanNumPhotons' to 'MeanNumberOfPhotons' in
G4Scintillation and G4Cerenkov to conform with the documentation in
the Application Developers Guide.
o Added G4ProcessType identifier to all processes constructors.
o Hadronic Processes:
------------------
+ management:
o Correctly set the type of a hadronic process.
Fixes problem report #744.
+ models/chiral_inv_phase_space/body:
o Memory leak fix for nuclear mass management in G4QPDGCode to use
G4 masses of nuclear fragments.
+ models/low_energy:
o Fix in elastic scattering for the case of target hydrogen: use
relativistic kinematic for the generation of the final state.
Fix tested in HARP.
+ stopping:
o Fixed bug in time of e- produced in bound decay of mu-.
o Management of processes:
-----------------------
+ Added forward declaration of G4UImessenger in G4ProcessTable header.
Fixes problem report #768.
o Optical Processes:
-----------------
+ Added G4ProcessType identifier to all processes constructors.
o Run:
---
+ Removed unnecessary usage of G4Allocator for allocation of a run.
o Tracking:
--------
+ Fix in G4SteppingManager::InvokeAlongStepDoItProcs() for problem
report #761.
+ Fix in G4SteppingManager::DefinePhysicalStepLength() for the order
of execution of 'ExclusivelyForced' processes like Fast-Simulation.
Problem reported and fixed in CMS and ATLAS.
o Physics lists:
-------------
+ hadronic: corrected text for the installation in README.
o Examples:
--------
+ Updated reference outputs.
+ extended/electromagnetic/TestEm9
o Fixed problem for changing cuts between runs.
+ extendedeventgenerator/exgps
o Fixed GNUMakefile for linking with AIDA on WIN32-VC.
Fixes problem report #767.
+ extended/medical/GammaTherapy
o Added vis.mac and histogram type (aida, root, hbook).
o Use standard angular distribution for low-energy PhotoElectric.
+ extended/persistency
o Added missing EXTRALIBS to link list for specialised setup.
+ extended/radioactivedecay/exrdm
o Fixed GNUMakefile for linking with AIDA on WIN32-VC.
Fixes problem report #767.
+ novice/N03
o RunAction: compute and print statistic at the end of the run.
