0002 Geant4 9.6 - patch-04 Release Notes
0003 -----------------------------------
0004
0005 30 January 2015
0006
0007 List of fixes included in this public patch since the public release 9.6.p03:
0008
0009 o Geometry:
0010 --------
0011 + navigation:
0012 o G4Navigator: corrected saving/restoring of 'navigator state'.
0013 o G4PathFinder: added EndTrack() method, to reset internal state
0014 and inform G4TransportationManager to use 'ordinary' Navigator.
0015 o Fix in G4MultiNavigator to properly set 'fIdNavLimiting' index to
0016 navigator limiting the step, if only one navigator limits the step.
0017 + solids/specific:
0018 o Fixed triangularisation method AddGeneralPOlygoneFacets() in
0019 G4ExtrudedSolid by avoiding flat triangles. Added warning message to
0020 G4TriangularFacet constructor if Area is 0; i.e., case of flat triangle.
0021 Addressing problem report #1703.
0022 o Get rid of deprecated 'register' storage class specifier in source files.
0023 + volumes
0024 o Avoid post-increment in G4NavigationLevelRep::AddAReference().
0025
0026 o Global:
0027 ------
0028 + Fix in G4SimplexDownhill header to proper define header guard.
0029 + Updated date and version for 9.6.p04.
0030
0031 o Generic Processes:
0032 -----------------
0033 + Management:
0034 o Fixed logic in G4ProcessManager::SetProcessOrderingToSecond() to make
0035 sure the process is always set before the process that has ordering
0036 index 1.
0037 + Transportation:
0038 o Fix in G4CoupledTransportation to message G4PathFinder for resetting
0039 to the default navigator as the 'standard' Mass navigator at end of
0040 tracking. Avoid use of multi-navigator when it should not be used.
0041 o Fix in G4Transportation to save pointer to particle change as required
0042 by G4VProcess interface.
0043
0044 o Hadronic Processes:
0045 ------------------
0046 + management:
0047 o G4HadronicProcess::CheckResult(): added check for dynamic mass
0048 to correspond to PDG mass within ~10%.
0049 + models/binary_cascade:
0050 o G4BinaryCasacde: improved calculation of mass, and of correction for
0051 outgoing particles by always using GetIon() method; addresses potential
0052 crash for p+d seen in d+H in BIC.
0053 o G4{Proton,Neutron}Field: protect against negative index into buffer.
0054 + models/cascade:
0055 o G4CascadeInterface: fixed possible infinite-loop condition where
0056 (nTries >= maxTries) and momentum balance fails.
0057 o G4InuclNuclei: fix case of floating-point exception in
0058 setExcitationEnergy() for zero Ekin.
0059 o Fix for memory leak in secondaries in G4IntraNucleiCascader.
0060 Addressing problem report #1584.
0061 + models/parton_string:
0062 o Fix for rare crash in G4LundStringFragmentation in the case of
0063 anti-sigma+ capture at rest on hydrogen.
0064 + stopping:
0065 o G4MuMinusCapturePrecompound: added simplified model for capture in
0066 deuterium and in He4; reduced number of trials to find neutrino
0067 4-momentum from 1000 to 100; added protection 1 keV for negative
0068 excitation energy, and substituted FatalException by JustWarning.
0069 Addressing rare cases of infinite loop reported by ATLAS.
0070 o G4AntiProtonAnnihilationAtRest: fixed bug related to a wrong target
0071 sampling (always the last element of the element vector was sampled
0072 as target).
0073 o G4HadronStoppingProcess, G4MuonMinusBoundDecay: fixed time of muon
0074 nuclear capture secondaries. Addressing problem report #1695.
0075 o Fix for Coverity defects in G4MuonMinusCaptureAtRest.
0076
0077 o Intercoms:
0078 ---------
0079 + G4GenericMessenger: fixed case of core dump when GetCurrentValue()
0080 method is invoked for a command defined by DeclareMethod().
0081 + Corrected inclusion protection flag in G4GenericMessenger.hh.
0082 Addressing old problem report #1527.
0083 + Fixed treatment of double-quotes in G4UImanager::ForeachS().
0084 Addressing problem report #1614.
0085
0086 o Interfaces:
0087 ----------
0088 + Explicitly set the LC_NUMERIC locale to "C" in G4Qt.
0089 Addressing problem report #1487.
0090 Fixed problem with resizing the QGLwidget when scene is opened from UI.
0091
0092 o Persistency:
0093 -----------
0094 + ascii:
0095 o Corrected dump of 'phi' and 'theta' for G4Trap and G4Para in dumper.
0096 Addressing problem report #1602.
0097 + gdml:
0098 o Fixed typo in G4GDMLWriteSolids::BooleanWrite() for the case of repeated
0099 displacements of the reference solid in the same Boolean operation (issue
0100 reported by ATLAS).
0101 o Correction to G4GDMLReadMaterials::MixtureRead() to revert order of
0102 reading (first elements then materials) for mixtures by fraction;
0103 corrects referencing for cases when elements and materials may carry
0104 the same name (case reported by ATLAS).
0105 o Correction to G4GDMLRead::Read() for the case when schema validation
0106 is turned off, to disable initialisation of validation machinery in the
0107 parser and allow for standalone parsing off-network.
0108 Added better description to fatal exception in case document content
0109 imported happens to be empty in G4GDMLRead::Read().
0110 o Corrected minor Coverity defect in G4GDMLParser for uninitialised
0111 'strip' flag in constructors.
0112 o Corrected potential memory leak in G4GDMLReadSolids.
0113 o Corrected dump of 'phi' and 'theta' for G4Trap and G4Para in writer.
0114 Addressing problem report #1602.
0115 o Get rid of deprecated 'register' storage class specifier in source files.
0116 o Added comparison operator for 3-vector key in 'vertexMap' in
0117 G4GDMLWriteSolids for export of tessellated solid.
0118 Addressing problem report #1573.
0119
0120 o Examples:
0121 --------
0122 + Updated reference outputs.
