All notable changes to FairRoot will be documented in this file.
The format is based on Keep a Changelog,
- The output folder name changed from 'folderName_0' to 'folderName'. In the MT mode of Geant4 the folder names changed from 'folderName_1' and 'folderName_2' to 'folderName'.
- Check the return value of
source->InitUnpackers()
/source->ReinitUnpackers()
inFairRunOnline
. Stop run iffalse
returned. - Remove sink from Tutorial3/MQ/sampler.cxx.
- Allow running without output sink. In this case even persistent branches would not be stored anywhere.
- Move online related code into the new Online library
- The special steering class FairRunOnline was moved from the Base into the Online library.
- Also the MBS/LMD related source classes were moved to the new Online library.
- If one of these classes are used in your code, you need
to link against new target
FairRoot::Online
.
- Dropped
CheckCXX11Features
(This was also released in 18.6.8 and 18.4.8)- FairRoot assumes a recent compiler that fully supports C++17.
- Remove the following things from your
CMakeLists.txt
:-
Set(CheckSrcDir "${FAIRROOTPATH}/share/fairbase/cmake/checks")`
-
include(CheckCXX11Features)
-
IF(HAS_CXX11_SHAREDPOINTER) Add_Definitions(-DHAS_SHAREDPOINTER) ENDIF(HAS_CXX11_SHAREDPOINTER)
-
- If your C++ code depends on
HAS_SHAREDPOINTER
being set, rewrite it accordingly. - If any of your CMake code depends on
HAS_CXX11_*
being set, rewrite it accordingly. - If your code has specific C++ needs, consider CMake's
target_compile_features()
.
- Dropped
CHECK_EXTERNAL_PACKAGE_INSTALL_DIR
- Just remove it from your
CMakeLists.txt
.
- Just remove it from your
- Dropped
USE_PATH_INFO
CMake option. It was an anti-pattern. Don't use it! - Dropped
ROOT_GENERATE_ROOTMAP
. It was used on ROOT 5.x.- Rewrite your build system, if you still use it.
FairRootManager::Get{Tree,Folder}Name()
now returnconst char *
. Do NOTdelete
the returned pointer!FairRunSim::SetSimulationConfig()
now takes aunique_ptr
instead of a raw pointer with unknown ownership.- Some headers were cleaned up and now
#include
fewer other headers. You might have to add some#includes
s in your code. - Added a new build switch
BUILD_BASEMQ
for controlling whetherFairRoot::BaseMQ
and dependent targets are built (FairRoot::FairMQ
andFairRoot::ParMQ
). It is enabled by default and will now require its external package dependencies FairMQ and Boost. - Boost serialization support for
FairTimeStamp
,FairHit
, andFairMCPoint
has been moved to theFairRoot::BaseMQ
target to haveFairRoot::Base
no longer depend on Boost.Serialization. The user must opt-in to the previously baseline Boost serialization support by including one of the new headers, e.g. forFairHit
:There is also a convenience header#include <FairHit.h> #include <FairHitBoostSerializationSupport.h>
<FairBoostSerializationSupport.h>
which includes all class-based support headers currently offered.
This release of FairRoot deprecates many APIs for various reasons. If you think you really require some API, please file an issue, so that we can see how to handle this.
- Deprecating MbsAPI
- This release deprecates MbsAPI.
- It will be disabled by default in FairRoot 19.
- We plan to remove it completely in FairRoot 20.
- If you need it, speak up NOW.
- This release deprecates MbsAPI.
- Deprecate some singleton-like APIs:
FairRunAnaProof::Instance()
- keep a pointer to the object after instantiating it in your code.FairRadGridManager::Instance()
- Consider using theGetRadGridMan()
method onFairMCApplcation
.FairRadMapManager::Instance
,FairRadLenManager::Instance
FairGeaneApplication::Instance
- Deprecated some other APIs
FairGeoVector::round
was nonfunctional and never did anything.FairTask::*InputPersistance
: There's no getter forfInputPersistance
, no other code in FairRoot uses the setters, we're not aware of anyone using it.FairFieldFactory::fCreator
points tothis
.FairRootManager::FillEventHeader
is only a wrapper aroundFairSource::FillEventHeader
.FairModule::ConstructASCIIGeometry(T*, TString, U*)
, useFairModule::ConstructASCIIGeometry(TString)
instead.
- Many items were already deprecated in prior versions. Marked them with proper C++14 deprecation warnings. Scheduled them for removal in v20.
- Deprecated DataMatch library
- Contact the developers should you need it.
- Scheduled to remove without replacement in a future major release of FairRoot.
-
CMake targets for libraries are now exported. Some have names different from the filesystem library name.
Old Library Name Target Name TrkBase FairRoot::TrackBase
FairDataMatch FairRoot::DataMatch
FairTools FairRoot::Tools
FairFastSim FairRoot::FastSim
FairMCStepLogger FairRoot::MCStepLogger
All those not listed here have the library name prefixed with
FairRoot::
as the target name. -
Note that the library filesystem name is scheduled to be changed in 19.2 to a
fairroot-trackbase
style naming. For those using the targets this change will not be visible. -
Tests using Geant3 have been disabled by default, because those tests have a probability > 0 for failing. If you want to run them anyways, pass
-DENABLE_GEANT3_TESTING=ON
to CMake. -
Undeprecate
FairRootManager::GetOut{File,Tree}
It has been deprecated since 18.0.0.
