Geant4 9.6 - patch-04 Release Notes
-----------------------------------
30 January 2015
List of fixes included in this public patch since the public release 9.6.p03:
o Geometry:
--------
+ navigation:
o G4Navigator: corrected saving/restoring of 'navigator state'.
o G4PathFinder: added EndTrack() method, to reset internal state
and inform G4TransportationManager to use 'ordinary' Navigator.
o Fix in G4MultiNavigator to properly set 'fIdNavLimiting' index to
navigator limiting the step, if only one navigator limits the step.
+ solids/specific:
o Fixed triangularisation method AddGeneralPOlygoneFacets() in
G4ExtrudedSolid by avoiding flat triangles. Added warning message to
G4TriangularFacet constructor if Area is 0; i.e., case of flat triangle.
Addressing problem report #1703.
o Get rid of deprecated 'register' storage class specifier in source files.
+ volumes
o Avoid post-increment in G4NavigationLevelRep::AddAReference().
o Global:
------
+ Fix in G4SimplexDownhill header to proper define header guard.
+ Updated date and version for 9.6.p04.
o Generic Processes:
-----------------
+ Management:
o Fixed logic in G4ProcessManager::SetProcessOrderingToSecond() to make
sure the process is always set before the process that has ordering
index 1.
+ Transportation:
o Fix in G4CoupledTransportation to message G4PathFinder for resetting
to the default navigator as the 'standard' Mass navigator at end of
tracking. Avoid use of multi-navigator when it should not be used.
o Fix in G4Transportation to save pointer to particle change as required
by G4VProcess interface.
o Hadronic Processes:
------------------
+ management:
o G4HadronicProcess::CheckResult(): added check for dynamic mass
to correspond to PDG mass within ~10%.
+ models/binary_cascade:
o G4BinaryCasacde: improved calculation of mass, and of correction for
outgoing particles by always using GetIon() method; addresses potential
crash for p+d seen in d+H in BIC.
o G4{Proton,Neutron}Field: protect against negative index into buffer.
+ models/cascade:
o G4CascadeInterface: fixed possible infinite-loop condition where
(nTries >= maxTries) and momentum balance fails.
o G4InuclNuclei: fix case of floating-point exception in
setExcitationEnergy() for zero Ekin.
o Fix for memory leak in secondaries in G4IntraNucleiCascader.
Addressing problem report #1584.
+ models/parton_string:
o Fix for rare crash in G4LundStringFragmentation in the case of
anti-sigma+ capture at rest on hydrogen.
+ stopping:
o G4MuMinusCapturePrecompound: added simplified model for capture in
deuterium and in He4; reduced number of trials to find neutrino
4-momentum from 1000 to 100; added protection 1 keV for negative
excitation energy, and substituted FatalException by JustWarning.
Addressing rare cases of infinite loop reported by ATLAS.
o G4AntiProtonAnnihilationAtRest: fixed bug related to a wrong target
sampling (always the last element of the element vector was sampled
as target).
o G4HadronStoppingProcess, G4MuonMinusBoundDecay: fixed time of muon
nuclear capture secondaries. Addressing problem report #1695.
o Fix for Coverity defects in G4MuonMinusCaptureAtRest.
o Intercoms:
---------
+ G4GenericMessenger: fixed case of core dump when GetCurrentValue()
method is invoked for a command defined by DeclareMethod().
+ Corrected inclusion protection flag in G4GenericMessenger.hh.
Addressing old problem report #1527.
+ Fixed treatment of double-quotes in G4UImanager::ForeachS().
Addressing problem report #1614.
o Interfaces:
----------
+ Explicitly set the LC_NUMERIC locale to "C" in G4Qt.
Addressing problem report #1487.
Fixed problem with resizing the QGLwidget when scene is opened from UI.
o Persistency:
-----------
+ ascii:
o Corrected dump of 'phi' and 'theta' for G4Trap and G4Para in dumper.
Addressing problem report #1602.
+ gdml:
o Fixed typo in G4GDMLWriteSolids::BooleanWrite() for the case of repeated
displacements of the reference solid in the same Boolean operation (issue
reported by ATLAS).
o Correction to G4GDMLReadMaterials::MixtureRead() to revert order of
reading (first elements then materials) for mixtures by fraction;
corrects referencing for cases when elements and materials may carry
the same name (case reported by ATLAS).
o Correction to G4GDMLRead::Read() for the case when schema validation
is turned off, to disable initialisation of validation machinery in the
parser and allow for standalone parsing off-network.
Added better description to fatal exception in case document content
imported happens to be empty in G4GDMLRead::Read().
o Corrected minor Coverity defect in G4GDMLParser for uninitialised
'strip' flag in constructors.
o Corrected potential memory leak in G4GDMLReadSolids.
o Corrected dump of 'phi' and 'theta' for G4Trap and G4Para in writer.
Addressing problem report #1602.
o Get rid of deprecated 'register' storage class specifier in source files.
o Added comparison operator for 3-vector key in 'vertexMap' in
G4GDMLWriteSolids for export of tessellated solid.
Addressing problem report #1573.
o Examples:
--------
+ Updated reference outputs.
----------------------------------------------------------------------------
