159<H2>6. Items for migration of the user code</H2>
160
161Some migrations may be necessary for advanced uses of features in Geant4
162in order to upgrade from release 7.1 to release 8.0. Note that a full reinstallation
163of libraries (or a full recompilation) and a recompilation of user applications
164is required.
165
166<P> </P>
167<B>Creating and instantiating physics lists : impact of the revised, "non-static", particle
168definitions</B>
169<P> </P>
170In this release, all particle-definition  objects are instantiated dynamically
171when the method <TT>ConstructParticle()</TT> of the user's <TT>G4VUserPhysicsList</TT> is
172 called.
173This method is invoked when the user's physics list is assigned to the
174<TT>G4RunManager</TT> (whereas previously it was called  at the
175time of
176<TT>G4RunManager::Initialize()</TT>). The new scheme allows the
177user to set  a number physics quantities to alternative values (e.g. masses of
178elementary particles) before particles are instantiated with the values provided by Geant4.
179This new scheme creates some restrictions which can
180affect on the existing users's codes, in particular when user-defined
181physics lists are used:
182<OL>
183<LI>Physics processes and models must be instantiated in the
184    <TT>ConstructProcess()</TT> method of the user's physics list.<BR>
185    In particular physics processes or models <em>must not</em> be data members of a physics
186    list. The reason is that some existing physics processes and models require
187    that particles have been instantiated already. If a process is a data member
188    of the physics list, it is instantiated when the physics list's constructor
189    is called, and thus before the invocation of <TT>ConstructParticle()</TT>.<BR>
190    The "educated-guess" physics lists distributed with previous Geant4 releases
191    are affected by this change. The revised physics lists, which are distributed
192    with this release, should be used in their place.
193    A user adopting his/her own physics list, will need to perform a similar
194    revision in case a <TT>G4Exception</tt> with the following message occurs
195    when  the physics list is instantiated:<BR>
196    <em>Error message</em>:
197    <PRE>
198      Access to G4ParticleTable for finding a particle or equivalent operation
199      occurs before G4VUserPhysicsList is instantiated and assigned to
200      G4RunManager. Such access is prohibited by Geant4 version 8.0.
201      To fix this problem, please make sure that your main() instantiates
202      G4VUserPhysicsList and set it to G4RunManager before instantiating
203      other user classes such as G4VUserPrimaryParticleGeneratorAction.
204    </PRE>
205    <em>Fix:</em>
206    All physics processes and models defined as data members of the physics
207    list must be moved to the <TT>ConstructProcess()</TT> method, and must be
208    explicitly instantiated by <TT>new</TT> operator. The revised physics lists
209    provide a reference for this revision.</LI>
210<LI>User action classes (derived from <TT>G4VUserPrimaryGeneratorAction,
211    G4UserRunAction, G4UserEventAction, G4UserStackingAction,
212    G4UserTrackingAction</TT> and <TT>G4UserSteppingAction</TT>) must be
213    instantiated after the physics list is instantiated and after it is set to
214    <TT>G4RunManager</TT>. Please note that the user's detector construction
215    class is a user initialization class and thus is not affected by this
216    restriction.<BR>
217    The user should revise the <TT>main()</TT> function if the following
218    <TT>G4Exception</TT> occurs:<BR>
219    <em>Error message</em> (for <TT>G4VUserPrimaryGeneratorAction</TT>):
220    <PRE>
221      You are instantiating G4VUserPrimaryGeneratorAction BEFORE your
222      G4VUserPhysicsList is instantiated and assigned to G4RunManager.
223      Such an instantiation is prohibited by Geant4 version 8.0. To fix this
224      problem, please make sure that your main() instantiates G4VUserPhysicsList
225      AND set it to G4RunManager before instantiating other user action classes
226      such as G4VUserPrimaryParticleGeneratorAction.
227    </PRE>
228    <em>Fix:</em>
229    Edit <TT>main()</TT> to make sure all user action classes are
230    instantiated after the physics list is set to <TT>G4RunManager</TT>.</LI>
231</OL>
232
233<P> </P>
234<B><TT>G4VProcess</TT> base class</B>
235<P> </P>
236A signature change is implemented in the <TT>G4VProcess</TT> base class.<BR>
237The virtual method <TT>StartTracking()</TT> defined in <TT>G4VProcess</TT>
238now takes <TT>const G4Track*</TT> as argument in its signature. Users
239implementing their own physics process and making use of this virtual
240method, will have to modify the signature accordingly.
241
242<P> </P>
243<B>Multiple Scattering electromagnetic process</B>
244<P> </P>
245In the electromagnetic standard package major changes have been introduced
246concerning the Multiple Scattering process. To improve the behaviour of low
247energy particles (electrons in particular, but affecting also hadrons),
248the Multiple Scattering now limits the step size for the particles. This
249restriction is undertaken using several criteria, and is applied systematically,
250in all volumes and materials. In addition a model of the correlation between
251lateral displacement and final direction has been implemented (see the
252Physics Reference Manual for further information).<BR>
253As a result, most physical observables become more stable when varying
254production cuts (i.e. less &quot;cut dependent&quot;). There is a corresponding
255cost, a CPU-time penalty, when utilising the same value of the production
256thresholds. This penalty can be significant, depending on the user's setup and
257the cut values. For many use cases the increased stability will allow the choice
258of higher production thresholds, recovering computing performance while
259maintaining physics performance.<BR>
260To enable the user to investigate its benefits, a mechanism is provided to
261deactivate this step limitation. The new method <TT>MscStepLimitation(bool)</TT>
262of <tt>G4MultipleScattering</tt> disables these new step limitations.
263In addition, in order to help the transition, the old version is available for
264this release 'frozen' in the class <TT>G4MultipleScattering71</TT>.
265Several examples (in extended/electromagnetic) provide sample physics lists
266which use this older version.
267
268<P> </P>
269<B>Geometry modeler</B>
270<P> </P>
271For setups including parameterised geometries by material, an interface
272extension is introduced in <TT>G4VPVParameterisation</TT> base class for the
273<TT>ComputeMaterial()</TT> method. An optional argument has been added, that
274provides a constant pointer to the touchable of the parent of the current
275volume, enabling access to its copy number and other properties, and those of
276all its ancestor volumes.
277User code making use of this feature will have to be updated accordingly.
278A compilation warning should flag to take into account this interface change.
279<P></P>
280Internal classes implementing the framework for twisted solids have been
281renamed. User code depending on this framework will have to be modified
282accordingly.
283
284<P> </P>
285<B>Fast parameterisation</B>
286<P> </P>
287The concept of "envelope" and "ghost-volume" for fast-parameterisation has
288been merged with the <TT>G4Region</TT> in this release. Therefore, a
289logical-volume no longer acts directly as an "envelope", since this attribute
290now assigned to <TT>G4Region</TT>. Please refer to the User Guide for
291Application Developers for the detailed information. The relevant modules have
292migrated accordingly. See <TT>exampleN05</TT> which has been revised to
293demonstrate this new mechanism.
294<P></P>
295A design iteration has taken place for the GFlash fast shower parameterisation
296model and some classes were renamed to follow the new implementation and
297design for envelopes. User code making use of the GFlash tool should migrate
298accordingly.
299<P></P>
300TRD models for cluster parameterisation have been retired. The functionality
301is now provided directly as physics processes and included in the
302<TT>electromagnetic</TT> packages.
303
304<P> </P>
305<B>Migration to <TT>&lt;sstream&gt;</TT> from deprecated
306   <TT>&lt;strstream&gt;</TT></B>
307<P> </P>
308<TT>&lt;strstream&gt;</TT> types are no longer in use by the Geant4 kernel in
309this release. Also any protection from compilation warnings by the compiler
310for deprecation of such header are no longer implicitely included. User code
311therefore will be exposed to implement such migration to
312<TT>&lt;sstream&gt;</TT>, if not already done.
313
314<P> </P>
315<B>System of Units and Physical Constants</B>
316<P> </P>
317Geant4 8.0 can be used either with version 1.9.2.2 of CLHEP or 2.0.2.2.
318Explicit usage of the <TT>CLHEP</TT> and <TT>HepGeom</TT> namespaces is
319made in the Geant4 code. However, for what concerns Units and Physical
320Constants, these are still kept available in the global namespace for
321convenience and backward-compatibility.

851    <LI>Added <em>enhanced trajectory drawing</em> to let interactively change
852        how trajectories are modeled. Initial options are
853        <TT>/vis/modeling/trajectories/create/drawByCharge</TT> and
854        <TT>/vis/modeling/trajectories/create/drawByParticleID</TT>, with
855        additional commands to set specific colors.
856        Coming in the next release will be <TT>drawByMomentum</TT>,
857        <TT>drawByOriginLogicalVolume</TT>, etc.
858        There is also a mechanism to let define a user's own <tt>drawBy</tt>
859        class and then invoke it from the command line. More information can
