Geant4 10.4 - patch-03 Release Notes
|
|
------------------------------------
|
|
|
|
8 February 2019
|
|
|
|
List of fixes included in this public patch since the public release 10.4.p02:
|
|
|
|
o Configuration:
|
|
-------------
|
|
+ CMake:
|
|
o Corrected URLs for data installation to use https; added -L flag to curl
|
|
to follow redirects when accessing a dataset URL.
|
|
o Geant4MakeRules_cxx.cmake: added -DGL_SILENCE_DEPRECATION to
|
|
CMAKE_CXX_FLAGS_INIT for clang to silence GL deprecation compilation
|
|
warnings on MacOS 10.14 Mojave.
|
|
+ GNUMake:
|
|
o Fixed setting of G4RUNPATHOPTION in Darwin/Linux-clang/g++ and binmake.cmk.
|
|
Addressing problem report #2086.
|
|
o Cleanup settings for GL in Darwin-clang.gmk and Darwin-g++.gmk.
|
|
Added -DGL_SILENCE_DEPRECATION to CPPFLAGS to silence GL deprecation
|
|
compilation warnings on MacOS 10.14 Mojave.
|
|
|
|
o Analysis:
|
|
--------
|
|
+ Fixed a deadlock issue with G4RootPNtupleManager where the mutex
|
|
was locked before being passed to Root.
|
|
+ Fixed compilation warnings on gcc-8.1.0.
|
|
|
|
o Geometry:
|
|
--------
|
|
+ management:
|
|
o Use reverse_iterator in G4SolidStore::DeRegister() in order to speedup
|
|
partial deregistration on setups with many solids instances.
|
|
o G4Region: added possibility to disable search in the tree in
|
|
AddRootLogicalVolume() for speeding up process in complex flat geometries.
|
|
|
|
o Global:
|
|
------
|
|
+ G4PhysicsVector, G4Physics2DVector: fixed possible out-of-bound access
|
|
in FindBin() method. Addressing problem report #2087.
|
|
+ Updated date and version for 10.4.p03.
|
|
|
|
o Interfaces:
|
|
----------
|
|
+ G4Xt: fixed compilation warnings for casts on gcc-8.1.
|
|
+ Fixed compilation warnings for not used return parameters.
|
|
|
|
o Persistency - gdml
|
|
------------------
|
|
+ Clear auxiliary map information in G4GDMLReadStructure::Clear().
|
|
Addressing problem report #2064.
|
|
+ Added stripping of invalid characters for names generation in writer classes
|
|
to prevent invalid NCName strings in exported GDML files. Adopt properly
|
|
stripped generated strings for exporting names of optical surfaces.
|
|
|
|
o Processes - Electromagnetic:
|
|
---------------------------
|
|
+ dna:
|
|
o Fixed header guards in G4ITFinder and G4AllITFinder.
|
|
Addressing problem report #2084.
|
|
+ standard:
|
|
o G4GoudsmitSaundersonTable: fixed gcc-8.1.0 compilation warnings.
|
|
+ utils:
|
|
o G4EmElementSelector: optimisation of element selection for compound
|
|
materials.
|
|
+ xrays:
|
|
o G4Cerenkov, G4Scintillation: correctly reset number of photons
|
|
to 0 each step. Addressing problem report #2056.
|
|
Added protection against infinite loops due to very small steps.
|
|
Addressing problem report #1992.
|
|
|
|
o Processes - Hadronic:
|
|
--------------------
|
|
+ management:
|
|
o G4HadronicProcess: added check if secondary particle is on the mass
|
|
shell; if its mass differ from the PDG mass more for 1.5 MeV then mass
|
|
is forced to the mass shell, energy conserved, but momentum is changed.
|
|
Use correct return type when calling CheckResult() from PostStepDoIt():
|
|
fixes case when the value of pointer 'result' does not get properly
|
|
reset to NULL in case a non-conservation is detected, thus "bad"
|
|
interaction does not get re-sampled.
|
|
Fixed compilation warnings on gcc-8.1.0 regarding catching polymorphic
|
|
type by value, instead of by reference.
|
|
o G4HadronicProcess, G4VLeadingParticleBiasing, G4HadLeadBias: fixed
|
|
compilation warning with gcc-7.
|
|
+ models/binary_cascade
|
|
o G4GeneratorPrecompoundInterface: fixed printout typo.
|
|
+ models/cascade:
|
|
o G4GDecay3: fixed problem reported by CMS due to wrong kinematics in
|
|
the final state by removing loop check; adding protection for low value
|
|
of mother mass.
|
|
+ models/de_excitation:
|
|
o G4LevelReader: fixed initialisation of 'fAlphaMax' from 1.e+6 to 1.e+15;
|
|
needed for correct IC probability of some isotopes.
|
|
Addresses problem reports #1986 and #2076, by change of handling of
|
|
internal conversion data.
|
|
+ models/particle_hp
|
|
o G4ParticleHPCaptureFS::ApplyYourself(): Lorentz boost of neutron into
|
|
target frame was backwards; reversed it. Also replaced SetDefinition()
|
|
with SetDefinitionAndUpdateE(). Addresses problem report #1919.
|
|
o Fixed definition of singletons for G4ParticleHPManager and
|
|
G4ParticleHPThreadLocalManager and some code cleanup.
|
|
Made G4ParticleHPThreadLocalManager a G4ThreadlLocalSingleton to avoid
|
|
memory leaks generated each time a thread creates the instance.
|
|
o Fixed bug for double allocation of G4ParticleHPReactionWhiteBoard in
|
|
G4ParticleHPThreadLocalManager::OpenReactionWhiteBoard().
|
|
o G4ParticleHPElementData: removed unnecessary inheritance from
|
|
G4HadronicCrossSection.
|
|
o Fixed incorrect sampling of isotropic distribution.
|
|
Addressing problem report #1745.
|
|
o Fixed gamma level mismatch in G4ParticleHPInelasticCompFS.
|
|
Not a complete fix because gamma data comes from ENSDF and does not
|
|
necessarily match excitations in ENDF.
|
|
Addressing problem report #1789.
|
|
o Fixed memory leaks in G4ParticleHPContEnergyAngular::Sample() and
|
|
G4ParticleHPContAngularPar::cacheInit().
|
|
Addressing problem report #2026.
|
|
o G4ParticleHPElasticFS::ApplyYourself(): use correct reference frames for
|
|
calculation of projectile and target momenta. Correction made for cases
|
|
when cos(Theta) is given in lab frame and in center of momentum frame.
|
|
Partial fix of momentum non-conservation for problem report #1918.
|
|
o Fixed potential leaks in G4ParticleHPPhotonDist, G4ParticleHPContAngularPar
|
|
and G4ParticleHPFinalState for use of pointers cached in G4Cache.
|
|
o G4ENDFTapeRead, G4FissionProductYieldDist: fixed compilation warnings
|
|
on gcc 8.1.0, regarding catching polymorphic type by value, instead of
|
|
by reference.
|
|
o Minor code cleanup and formatting.
|
|
+ models/parton_string/diffraction
|
|
o G4FTFAnnihilation: fix to get flat cos(theta) and phi distributions for
|
|
antiproton annihilation at rest.
|
|
+ models/rpg
|
|
o G4RPGAntiKZeroInelastic, G4RPGInelastic: fixed compilation warnings on
|
|
gcc-8.1.0, regarding catching polymorphic type by value, instead of by
|
|
reference.
|
|
+ processes:
|
|
o G4HadronElasticProcess, G4NeutrinoElectronProcess: fixed compilation
|
|
warnings on gcc 8.1.0, regarding catching polymorphic type by value,
|
|
instead of by reference.
|
|
+ stopping:
|
|
o G4HadronStoppingProcess, G4MuonicAtomDecay: fixed compilation warnings
|
|
on gcc 8.1.0, regarding catching polymorphic type by value, instead of
|
|
by reference.
|
|
|
|
o Processes - Scoring:
|
|
-------------------
|
|
o G4ParallelWorldProcess: fixed track velocity of optical photons for the
|
|
first step in a layered mass geometry.
|
|
|
|
o Examples:
|
|
--------
|
|
+ extended/fieldBlineTracer:
|
|
o Fixed compilation error for missing header inclusion.
