Geant4 4.0 - patch-01 Release Notes
|
|
-----------------------------------
|
|
|
|
31st January 2002
|
|
|
|
List of fixes included in this public patch to release 4.0:
|
|
|
|
o Event:
|
|
-----
|
|
- G4PrimaryTransformer: removed check whether the primary vertex is
|
|
inside the world volume. The check has been moved to G4SteppingManager.
|
|
|
|
o Geometry:
|
|
--------
|
|
- Magnetic field:
|
|
o Activated G4DEBUG_FIELD in GNUmakefile.
|
|
o G4MagHelicalStepper.cc: renamed local variables "*Momentum*"
|
|
to "*Velocity*".
|
|
- Management:
|
|
o G4AffineTransform.icc: fixed trivial compilation warning for gcc-2.95.2.
|
|
- Volumes:
|
|
o G4AuxiliaryNavServices: critical fix, to only consider whether a
|
|
'ray' (Point,Direction) is on the surface (it was erroneously also
|
|
checking for those inside volumes). This erroneous condition occurred
|
|
frequently in the new usage of Locate with Direction to initialise a
|
|
step.
|
|
o G4Navigator: reset blocked volume when locating 'within volume',
|
|
after ensuring that it does not get called when ComputeSafety() is at
|
|
a boundary. Fixes cases of longstanding 'Point P is Inside' errors.
|
|
o Activated mechanism in GNUmakefile for allowing compilation with
|
|
G4DEBUG_FIELD or G4DEBUG_NAVIGATION flags.
|
|
- solids/Boolean:
|
|
o Moved all verbosity mode warnings to G4BOOLDEBUG.
|
|
o Activated G4BOOLDEBUG mechanism in GNUmakefile.
|
|
- solids/BREPS:
|
|
o G4BREPSolidPCone: bugfix for problem report #320.
|
|
Fixed missing use-case in constructor when RMAX and RMIN have been
|
|
changed for 2 consecutive equal z-values. Now it creates correctly
|
|
2 planar surfaces as expected.
|
|
Added private method ComputePlanarSurface() gained
|
|
by refactoring of some part of the code in the constructor.
|
|
o G4FPlane: fixed first constructor adding new argument for setting
|
|
explicitly the sense of a surface if required.
|
|
Fixed G4FPlane::Intersect() method which incorrectly ignored a special
|
|
case of a hit on surface point with ray direction opposite to surface
|
|
normal.
|
|
- solids/CSG:
|
|
o G4Sphere.cc: fixed a problem with tolerances in the case of large Radius.
|
|
o Moved all verbosity mode warnings to G4CSGDEBUG.
|
|
o Activated G4CSGDEBUG mechanism in GNUmakefile.
|
|
|
|
o Global:
|
|
------
|
|
- G4strstreambuf: plugged memory leak in destructor for buffer deletion.
|
|
Temporary fix to G4strstream::overflow(c) for GNU gcc-3.X compilers
|
|
(also problem report #342), which require returning of character 'c' in
|
|
case of buffer flushing for <CR>.
|
|
- Replaced 'NULL' with '0' in G4Allocator.hh, G4strstreambuf.icc
|
|
and G4Timer.cc.
|
|
- Removed obsolete inline definitions in g4std/wrappers/DEC-cxx/cmath.
|
|
|
|
o Materials:
|
|
---------
|
|
- Fixed G4MaterialPropertyVector::AddElement() to consider ordering
|
|
of elements.
|
|
|
|
o Track & Tracking:
|
|
----------------
|
|
- track:
|
|
o G4Track: corrected initialization of fStepLength in constructors.
|
|
Fixed bug in assignment operator for fStepLength.
|
|
- tracking:
|
|
o G4SteppingManager:
|
|
- fix safe comparison between floating numbers
|
|
- added check for primary track outside of the world
|
|
- bug fix for particles below threshold to avoid double steps
|
|
|
|
o Visualization:
|
|
-------------
|
|
- Corrected handling for already open file in HepRepXMLWriter.
|
|
|
|
o Examples:
|
|
--------
|
|
- Novice: syncronised files with CVS HEAD. No functional changes to code.
|
|
