Geant4 4.0 - patch-01 Release Notes
3+
-----------------------------------
4+
5+
31st January 2002
6+
7+
List of fixes included in this public patch to release 4.0:
8+
9+
o Event:
10+
-----
11+
- G4PrimaryTransformer: removed check whether the primary vertex is
12+
inside the world volume. The check has been moved to G4SteppingManager.
13+
14+
o Geometry:
15+
--------
16+
- Magnetic field:
17+
o Activated G4DEBUG_FIELD in GNUmakefile.
18+
o G4MagHelicalStepper.cc: renamed local variables "*Momentum*"
19+
to "*Velocity*".
20+
- Management:
21+
o G4AffineTransform.icc: fixed trivial compilation warning for gcc-2.95.2.
22+
- Volumes:
23+
o G4AuxiliaryNavServices: critical fix, to only consider whether a
24+
'ray' (Point,Direction) is on the surface (it was erroneously also
25+
checking for those inside volumes). This erroneous condition occurred
26+
frequently in the new usage of Locate with Direction to initialise a
27+
step.
28+
o G4Navigator: reset blocked volume when locating 'within volume',
29+
after ensuring that it does not get called when ComputeSafety() is at
30+
a boundary. Fixes cases of longstanding 'Point P is Inside' errors.
31+
o Activated mechanism in GNUmakefile for allowing compilation with
32+
G4DEBUG_FIELD or G4DEBUG_NAVIGATION flags.
33+
- solids/Boolean:
34+
o Moved all verbosity mode warnings to G4BOOLDEBUG.
35+
o Activated G4BOOLDEBUG mechanism in GNUmakefile.
36+
- solids/BREPS:
37+
o G4BREPSolidPCone: bugfix for problem report #320.
38+
Fixed missing use-case in constructor when RMAX and RMIN have been
39+
changed for 2 consecutive equal z-values. Now it creates correctly
40+
2 planar surfaces as expected.
41+
Added private method ComputePlanarSurface() gained
42+
by refactoring of some part of the code in the constructor.
43+
o G4FPlane: fixed first constructor adding new argument for setting
44+
explicitly the sense of a surface if required.
45+
Fixed G4FPlane::Intersect() method which incorrectly ignored a special
46+
case of a hit on surface point with ray direction opposite to surface
47+
normal.
48+
- solids/CSG:
49+
o G4Sphere.cc: fixed a problem with tolerances in the case of large Radius.
50+
o Moved all verbosity mode warnings to G4CSGDEBUG.
51+
o Activated G4CSGDEBUG mechanism in GNUmakefile.
52+
53+
o Global:
54+
------
55+
- G4strstreambuf: plugged memory leak in destructor for buffer deletion.
56+
Temporary fix to G4strstream::overflow(c) for GNU gcc-3.X compilers
57+
(also problem report #342), which require returning of character 'c' in
58+
case of buffer flushing for <CR>.
59+
- Replaced 'NULL' with '0' in G4Allocator.hh, G4strstreambuf.icc
60+
and G4Timer.cc.
61+
- Removed obsolete inline definitions in g4std/wrappers/DEC-cxx/cmath.
62+
63+
o Materials:
64+
---------
65+
- Fixed G4MaterialPropertyVector::AddElement() to consider ordering
66+
of elements.
67+
68+
o Track & Tracking:
69+
----------------
70+
- track:
71+
o G4Track: corrected initialization of fStepLength in constructors.
72+
Fixed bug in assignment operator for fStepLength.
73+
- tracking:
74+
o G4SteppingManager:
75+
- fix safe comparison between floating numbers
76+
- added check for primary track outside of the world
77+
- bug fix for particles below threshold to avoid double steps
78+
79+
o Visualization:
80+
-------------
81+
- Corrected handling for already open file in HepRepXMLWriter.
82+
83+
o Examples:
84+
--------
85+
- Novice: syncronised files with CVS HEAD. No functional changes to code.
86+
87+

16+
- sys/HP-aCC.gmk: removed include path to
17+

18+
necessary.
19+

32+
33+
o Event:
34+

46+
o G4GeometryMessenger.cc: fixed local variable name not to clash with
47+

50+
o G4ReflectedSolid[.hh.cc]:

52+
for defining/accessing the reflected transformation.
53+

o G4RepresentationRelationshipCreator.cc: fixed unsafe usage of
79+
'<' operator.
80+
81+
o Hadronic processes:
82+
------------------
83+
o Fixes in pre-equilibrium and de-excitation generator models.
84+
o Fixed bug in doppler broadening in neutron-transport model:
85+
- Fixed sign error in calculation of effective luminosity.
86+
o Stopping: trivial bug-fix in pi-absorption at rest.
87+
o Util:
88+
- Trivial bug-fix, affecting K-absorption at rest.
89+
- G4Nucleus: moved definition of constructors/destructor from header to

91+
time on SUN-CC for static constants used to initialise members in
92+
inline constructors.
93+
o CHIPS model: fixed accuracy problem.
94+
o Optimised implementation in G4Fancy3DNucleus.cc to allow porting on

104+
G4Element and G4Isotope.
105+
106+
o Particles:
107+
---------
108+
- Fixed bug in the decay table for G4KaonMinus.
109+
110+
o Track & Tracking:
111+
----------------
112+
- track:
113+
o Added G4Track::CopyTrackInfo().
114+
o Optimised G4ParticleChange::AddSecondary() to properly use touchable
115+
handles.
116+
o Fixed a bug of changing parent weight in
117+
G4ParticleChange::UpdateStepForAlongStep().
118+
o Optimised implementation in G4Track::GetVelocity().
119+
- tracking:
120+
o G4SteppingManager2.cc:
121+
- fix for extra steps when the ApplyCuts flag is set
122+
- G4SteppingManager.hh: changed scope for 'SizeOfSelectedDoItVector'
123+
to allow porting on WIN-VC compiler.
124+

126+
o Visualization:
127+
-------------
128+
- HepRep: added check for missing hierarchy layers in HepRepXMLWriter.
129+
- Bug fix in modeling: removed Begin/EndPrimitives from G4HitsModel and
130+
G4TrajectoriesModel. This was causing nested calls to Begin/EndPrimitives
131+
(and thus to glNewList/EndList in OpenGL stored mode), since the
132+
trajectories and hits Draw methods themselves have Begin/EndPrimitives.
133+
134+
o Examples:
135+
--------
136+
- extended/electromagnetic/testem1,3,4,5:
137+

138+
- novice/N03:
139+
o New macros for tutorials/exercises.
