# Category proc-biasgen History
See `CONTRIBUTING.rst` for details of **required** info/format for each entry,
which **must** added in reverse chronological order (newest at the top).
It must **not** be used as a substitute for writing good git commit messages!
-------------------------------------------------------------------------------
## 2025-11-01 John Apostolakis (proc-biasgen-V11-03-00)
- Fixed initialistion in G4ParticleChangeForNothing, responsible for crash
when enabling track verbosity.
## 2024-07-18 Gabriele Cosmo (proc-biasgen-V11-02-01)
- Fixed reported Coverity defects, to use 'const G4String&' for avoiding
implicit copies.
- Basic C++11 corrections (use of nullptr, auto, etc...); code formatting.
## 2022-07-17 Vladimir Ivanchenko (proc-biasgen-V11-02-00)
- G4BOptnChangeCrossSection - fix Coverity warning
## 2022-11-23 Gabriele Cosmo (proc-biasgen-V11-00-02)
- Fixed compilation warnings for implicit type conversions on macOS/XCode 14.1.
## 2022-08-31, Gabriele Cosmo (proc-biasgen-V11-00-01)
- Fixed defects reported by Coverity in G4BOptnLeadingParticle, to use auto&.
## 2021-12-10 Ben Morgan (proc-biasgen-V11-00-00)

# History entries prior to 11.0
August 4, 2021 A. Ribon
- G4BOptrForceCollision : migrated to the new version of G4PhysicsModelCatalog
- proc-biasgen-V10-07-01
April 16th, 2021 B. Morgan
- Migrate build to modular CMake API
- proc-biasgen-V10-07-00
November 15th, 2019 M. Verderi
- Introduce leading particle biasing proc-biasgen-V10-05-00
This is made implementing the new biasing operation:
include/G4BOptnLeadingParticle.hh
src/G4BOptnLeadingParticle.cc
- G4BOptnChangeCrossSection:
add argument to:
void SetBiasedCrossSection(G4double xst);
as option to update the interaction length when
setting a new cross-section value:
void SetBiasedCrossSection(G4double xst, bool updateInteractionLength = false);
default value makes the change backward compatible.
November 24th, 2017 M. Verderi
- Fix G4BiasingProcessInterface for wrong setting of first/last
GPIL/DoIt flags in case charged particles. As the msc became
a pure along, this broke the initial logic based on the fact
that, before, physics processes always had a PostStepDoIt method.
- proc-biasgen-V10-03-00
November 15th, 2016, M. Verderi
- Fix one Coverity warning in G4ParallelGeometriesLimiterProcess.
- proc-biasgen-V10-02-06
November 3rd, 2016, M. Verderi
- Remove reference to obsolete G4BiasingAppliedCase BAC_DenyInteraction enum value
and related logic. DenyProcessPostStepDoIt(..) method in G4BOptnForceFreeFlight
was concerned by this logic change. (The related case has been merged and
is handled by ApplyFinalStateBiasing(...) in a more general manner since
proc-biasgen-V10-00-00.)
- proc-biasgen-V10-02-05
October 26th, 2016, M. Verderi
- Development tag for introducing parallel geometry capability in generic biasing:
- G4BiasingProcessInterface : checks for biasing operator in mass and parallel geometries
- G4ParallelGeometriesLimiterProcess : a new process that limits the step on the boundaries
of the parallel geometries (one instance handles all parallel geometries)
- G4BiasingProcessSharedData : data shared among biasing processes related to a same
G4ParticleDefinition ; extended to cary information related to parallel geometries.
G4BiasingProcessSharedData now also holds the static map of shared data and process
managers, this was held before by G4BiasingProcessInterface.
- G4BiasingHelper : extended to handle addition of G4ParallelGeometriesLimiterProcess
to process manager.
- proc-biasgen-V10-02-04
March 8th, 2016, M. Verderi
- Clean up for unused variable fParticleChange in G4BiasingProcessInterface
- proc-biasgen-V10-02-03
March 7th, 2016, M. Verderi
- Fix coverity warnings in src/G4BiasingProcessInterface.cc
- proc-biasgen-V10-02-02
January 20th, 2016, M. Verderi
- fix compilation warning in order initialization of data members
in src/G4BiasingProcessInterface.cc.
- proc-biasgen-V10-02-01
January 19th, 2016, M. Verderi
- fix various coverity warnings (unitialized variables). Should have no
effect. Fixes in:
src/G4BOptnChangeCrossSection.cc
src/G4BOptnCloning.cc
src/G4BOptnForceCommonTruncatedExp.cc
src/G4BOptnForceFreeFlight.cc
src/G4BOptrForceCollision.cc
src/G4BiasingProcessInterface.cc
include/G4BiasingProcessSharedData.hh
and minor cosmetics in:
include/G4BOptnCloning.hh
include/G4BOptnForceFreeFlight.hh
- proc-biasgen-V10-02-00
November 6th, 2015, M. Verderi
- fix non initialization of model IDs in MT mode.
- prevent "over initialization" of operators (each
first process of process managers were calling
these initializations).
- proc-biasgen-V10-01-01
November 6th, 2015, M. Verderi
- adaptation to using G4VAuxiliaryTrackInformation:
o creation of G4BOptrForceCollisionTrackData
o quite rewriting of G4BOptrForceCollision biasing operator,
removing many state variables used for bookeeping of tracks
which is now achieved much simplier by the aux. track info.
Comes together with related logic re-writting.
o Removal of dependencies to management/G4BiasingTrackData
now deleted since proc-biasmng-V10-01-00 .
- proc-biasgen-V10-01-00
November 14th, 2014 M.Verderi
- Serious fix in G4InteractionLawPhysical::
UpdateInteractionLengthForStep(...)
- proc-biasgen-V10-00-03
November 13th, 2014 M.Verderi
- Tentative fix of crach in optimized mode
missing initialization in second constructor of G4BiasingProcessInterface.
- proc-biasgen-V10-00-02
November 11th, 2014 M.Verderi
- fix Coverity bugs
- proc-biasgen-V10-00-01
November 11th, 2014 M.Verderi
- Introduce anticipated call to PostStepGPIL of wrapped processes
by G4BiasingProcessInterface. This allows to collect all
physics cross-sections at the first call to biasing operator.
- Adaptation to change of G4VBiasingOperation (suppression of
DenyProcessPostStepDoIt(...) ).
- tag : proc-biasgen-V10-00-00 .
October 10th, 2013 A.Howard
- Subdirectory and history file created.
