<H2>6. Items for migration of the user code</H2>
Some migrations may be necessary for advanced uses of features in Geant4
in order to upgrade from release 7.1 to release 8.0. Note that a full reinstallation
of libraries (or a full recompilation) and a recompilation of user applications
is required.
<P> </P>
<B>Creating and instantiating physics lists : impact of the revised, "non-static", particle
definitions</B>
<P> </P>
In this release, all particle-definition objects are instantiated dynamically
when the method <TT>ConstructParticle()</TT> of the user's <TT>G4VUserPhysicsList</TT> is
called.
This method is invoked when the user's physics list is assigned to the
<TT>G4RunManager</TT> (whereas previously it was called at the
time of
<TT>G4RunManager::Initialize()</TT>). The new scheme allows the
user to set a number physics quantities to alternative values (e.g. masses of
elementary particles) before particles are instantiated with the values provided by Geant4.
This new scheme creates some restrictions which can
affect on the existing users's codes, in particular when user-defined
physics lists are used:
<OL>
<LI>Physics processes and models must be instantiated in the
<TT>ConstructProcess()</TT> method of the user's physics list.<BR>
In particular physics processes or models <em>must not</em> be data members of a physics
list. The reason is that some existing physics processes and models require
that particles have been instantiated already. If a process is a data member
of the physics list, it is instantiated when the physics list's constructor
is called, and thus before the invocation of <TT>ConstructParticle()</TT>.<BR>
The "educated-guess" physics lists distributed with previous Geant4 releases
are affected by this change. The revised physics lists, which are distributed
with this release, should be used in their place.
A user adopting his/her own physics list, will need to perform a similar
revision in case a <TT>G4Exception</tt> with the following message occurs
when the physics list is instantiated:<BR>
<em>Error message</em>:
<PRE>
Access to G4ParticleTable for finding a particle or equivalent operation
occurs before G4VUserPhysicsList is instantiated and assigned to
G4RunManager. Such access is prohibited by Geant4 version 8.0.
To fix this problem, please make sure that your main() instantiates
G4VUserPhysicsList and set it to G4RunManager before instantiating
other user classes such as G4VUserPrimaryParticleGeneratorAction.
</PRE>
<em>Fix:</em>
All physics processes and models defined as data members of the physics
list must be moved to the <TT>ConstructProcess()</TT> method, and must be
explicitly instantiated by <TT>new</TT> operator. The revised physics lists
provide a reference for this revision.</LI>
<LI>User action classes (derived from <TT>G4VUserPrimaryGeneratorAction,
G4UserRunAction, G4UserEventAction, G4UserStackingAction,
G4UserTrackingAction</TT> and <TT>G4UserSteppingAction</TT>) must be
instantiated after the physics list is instantiated and after it is set to
<TT>G4RunManager</TT>. Please note that the user's detector construction
class is a user initialization class and thus is not affected by this
restriction.<BR>
The user should revise the <TT>main()</TT> function if the following
<TT>G4Exception</TT> occurs:<BR>
<em>Error message</em> (for <TT>G4VUserPrimaryGeneratorAction</TT>):
<PRE>
You are instantiating G4VUserPrimaryGeneratorAction BEFORE your
G4VUserPhysicsList is instantiated and assigned to G4RunManager.
Such an instantiation is prohibited by Geant4 version 8.0. To fix this
problem, please make sure that your main() instantiates G4VUserPhysicsList
AND set it to G4RunManager before instantiating other user action classes
such as G4VUserPrimaryParticleGeneratorAction.
</PRE>
<em>Fix:</em>
Edit <TT>main()</TT> to make sure all user action classes are
instantiated after the physics list is set to <TT>G4RunManager</TT>.</LI>
</OL>
<P> </P>
<B><TT>G4VProcess</TT> base class</B>
<P> </P>
A signature change is implemented in the <TT>G4VProcess</TT> base class.<BR>
The virtual method <TT>StartTracking()</TT> defined in <TT>G4VProcess</TT>
now takes <TT>const G4Track*</TT> as argument in its signature. Users
implementing their own physics process and making use of this virtual
method, will have to modify the signature accordingly.
<P> </P>
<B>Multiple Scattering electromagnetic process</B>
<P> </P>
In the electromagnetic standard package major changes have been introduced
concerning the Multiple Scattering process. To improve the behaviour of low
energy particles (electrons in particular, but affecting also hadrons),
the Multiple Scattering now limits the step size for the particles. This
restriction is undertaken using several criteria, and is applied systematically,
in all volumes and materials. In addition a model of the correlation between
lateral displacement and final direction has been implemented (see the
Physics Reference Manual for further information).<BR>
As a result, most physical observables become more stable when varying
production cuts (i.e. less &quot;cut dependent&quot;). There is a corresponding
cost, a CPU-time penalty, when utilising the same value of the production
thresholds. This penalty can be significant, depending on the user's setup and
the cut values. For many use cases the increased stability will allow the choice
of higher production thresholds, recovering computing performance while
maintaining physics performance.<BR>
To enable the user to investigate its benefits, a mechanism is provided to
deactivate this step limitation. The new method <TT>MscStepLimitation(bool)</TT>
of <tt>G4MultipleScattering</tt> disables these new step limitations.
In addition, in order to help the transition, the old version is available for
this release 'frozen' in the class <TT>G4MultipleScattering71</TT>.
Several examples (in extended/electromagnetic) provide sample physics lists
which use this older version.
<P> </P>
<B>Geometry modeler</B>
<P> </P>
For setups including parameterised geometries by material, an interface
extension is introduced in <TT>G4VPVParameterisation</TT> base class for the
<TT>ComputeMaterial()</TT> method. An optional argument has been added, that
provides a constant pointer to the touchable of the parent of the current
volume, enabling access to its copy number and other properties, and those of
all its ancestor volumes.
User code making use of this feature will have to be updated accordingly.
A compilation warning should flag to take into account this interface change.
<P></P>
Internal classes implementing the framework for twisted solids have been
renamed. User code depending on this framework will have to be modified
accordingly.
<P> </P>
<B>Fast parameterisation</B>
<P> </P>
The concept of "envelope" and "ghost-volume" for fast-parameterisation has
been merged with the <TT>G4Region</TT> in this release. Therefore, a
logical-volume no longer acts directly as an "envelope", since this attribute
now assigned to <TT>G4Region</TT>. Please refer to the User Guide for
Application Developers for the detailed information. The relevant modules have
migrated accordingly. See <TT>exampleN05</TT> which has been revised to
demonstrate this new mechanism.
<P></P>
A design iteration has taken place for the GFlash fast shower parameterisation
model and some classes were renamed to follow the new implementation and
design for envelopes. User code making use of the GFlash tool should migrate
accordingly.
<P></P>
TRD models for cluster parameterisation have been retired. The functionality
is now provided directly as physics processes and included in the
<TT>electromagnetic</TT> packages.
<P> </P>
<B>Migration to <TT>&lt;sstream&gt;</TT> from deprecated
<TT>&lt;strstream&gt;</TT></B>
<P> </P>
<TT>&lt;strstream&gt;</TT> types are no longer in use by the Geant4 kernel in
this release. Also any protection from compilation warnings by the compiler
for deprecation of such header are no longer implicitely included. User code
therefore will be exposed to implement such migration to
<TT>&lt;sstream&gt;</TT>, if not already done.
<P> </P>
<B>System of Units and Physical Constants</B>
<P> </P>
Geant4 8.0 can be used either with version 1.9.2.2 of CLHEP or 2.0.2.2.
Explicit usage of the <TT>CLHEP</TT> and <TT>HepGeom</TT> namespaces is
made in the Geant4 code. However, for what concerns Units and Physical
Constants, these are still kept available in the global namespace for
convenience and backward-compatibility.
<P> </P>
<B>New Installation flags</B>
<P> </P>
New installation flags have been introduced:
<UL>
<LI><TT>G4VIS_BUILD_RAYTRACERX_DRIVER, G4VIS_USE_RAYTRACERX</TT>:
