- Don't add extra weight variable when split()-ting binned datasets
(Savannah #93867)
o RooLinearVar
- In getBinning(), always create bin mappings on the fly (even
even createOnTheFly=kFALSE), just don't create ranges in the
input variable in the latter case (Savannah #82087)

Remove
using namespace std;
from Riostream.h, which has huge consequences for all of ROOT.
Riostream.h is now a simple wrapper for fstream, iostream, iomanip for backward compatibility; Riosfwd.h simply wraps iosfwd.
Because of templates and their inline functions, Riostream.h needed to be included in headers, too (e.g. TParameter.h), which violated the assumption that Riostream.h is not exposing its using namespace std to headers.
ROOT now requires R__ANSISTREAM, R__SSTREAM, which does not change the set of supported compilers.
Without "using namespace std", several identifiers are now prefixed by std::; e.g. roofit/* source files now have a using namespace std to keep their coding style.
TFile::MakeProject() now generates "using namespace std" to convert the CINT-style class names into C++ ones.

Import changes from development branch
==== Date: Wed Feb 20 22:33:28 2008 =====
o RooRealSumPdf
- Do _not_ use normalization of RooAbsPdf input components
in numerator of RooRealSumPdf expression since it is
already explicitly occurring in denominator of RooRealSumPdf.
(Fixes wrong normalization reported by Tristan)
o RooObjCacheManager
- Register owner of cache with each cache elememt to
facilitate callbacks
o RooAbsCacheElement
- Add storage for pointer to owner of cache and
supply setOwner() function
o RooAbsPdf
- Use RooObjCacheManager callback mechanism to zero
'last used normalization' pointer in RooAbsPdf
when the cache-owned object pointed is about
to be deleted.
o RooAbsArg
- Make crc32 function static
o RooWorkspace
- Add CodeRepo nested class that allows to store C++ code
of RooAbsArg derived classes that are not in ROOT distribution
but are contained in workspace. When reading any missing
class, code is compiled on the fly allowing for transparent
reading of workspace object from file. Code is found in
location pointed to from TClass objects. Additional search
path for declaration and implementation files can be provided
to be able to handle non-trivial cases.
- Add WSDir nested class that represents information contained
in workspace as read-only TDirectory for easy interactive use.
Directory representation is created using makeDir() member function.
o LinkDef3
- Add nested classes in RooWorkspace
===== Date: Wed Mar 26 23:04:26 2008 =====
o RooProdPdf
- Fix typo in ctor documentaion
- Improve error message in expectedEvents() when no extendable p.d.f.s are found
- Implement getConstraints() function to retrieve constraint p.d.f terms from product
expression given set of observables and set of parameters to be constrained.
o RooMsgService
- Add PROGRESS message level between INFO and WARNING
- Add globalKill level for messages to be able to quickly eliminate all messages below
a given level without interfering with the stream structore of RooMsgService
o RooPrintable
- Implement new printing interface with more details control over items printed trhough contents enum
(multiple ORable options) and style of printing (inline, single line, (verbose) multiline) with style
enum (exclusive options).
- Introduce generic virtual functions for printing of name,title,value,arguments,
and extras of each object.
- Each class can overload the default contents used for all printing
uses (inline,verbose,standard) etc as well as the default printing style invoked by Print()
o RooPlot,RooGenContext, RooAbsRealLValue,RooDataSet,RooNameSet,RooCustomizer, RooAbsGenContext, RooAddModel,
RooFitResult,RooCurve,RooAbsAnaConv,RooHist,RooAbsReal,RooAbsCollection,RooAddPdf,RooTable,RooAbsData,

RooLinearVar,RooTreeData,RooTreeData
- Update to new RooPrintable interface
o RooGenContext,RooAbsGenContext,RooAddGenContext,RooProdGenContext,RooConvGenContext,RooSimGenContext
- Implement attach() function to simplify management of changing parameters during lifetime of context
o RooAbsRealLValue
- Eliminate inFitRange() warning message as it is gives too many false warnings when used with
parameterized ranges
o RooCustomizer
- Make owning of contents optional to simplify release of created components
o RooAbsReal
- Implement new evaluation error logging mechanism. Rather than passing zero p.d.f values, push error message with
details on a static stack (if logging is enabled by e.g. RooMinuit).
- Augment functionality of createIntegral: explicitly allow integration over ranges with bounds parameterized in
in terms of other integrated observables. Integrals of this type are automatically recognized and cast
as recursive integrals in case of >1-D integrals to integrate over requested phase space.
- Add createIntObj() helper function for above functionaliy.
- Eliminate a lot of commented out debug code from createPlotProjection()
- Modify fillHistogram(): when plot observables are cloned, explicitly interconnect clones again to facilitate
proper plotting of N-D integrals with entangled parameterized ranges
- Add ScaleFactor() argument to fillHistogram to control use of histogram density correction scale factor in Z-scale
of filled histogram
o RooProduction
- Fix bug for persistence
o RooRealMPFE
- Extend client/server protocol with message to retrieve RooAbsReal evaluation error log from server side and
merge with error log on client side
o RooRealVar
- Introduced concept of non-shared alternative binnings(ranges) required to accommodate RooParamBinning ranges
that cannot be shared across instances because of their client/server connection to other objects in p.d.f
expression trees. Modify setBinning to automatically recognize non-shareable binnings and divert those to
non-shared alternative binning container.
- Add setRange([const char*,] RooAbsReal&,RooAbsReal&) methods to simplify creation of parameterized ranges.
o RooAbsArg
- Introduce concept of owned components with addOwnedComponents() interface to be able to make any RooAbsArg
object own any number of others. This can be used to simplify the memory management of object trees
- Introduce prohibitServerRedirect mode that will trigger fatal assert if any server redirect is attempted
to thus configured object. Useful as debugging tool to track faulty copy constructors that leave clone
object tree unintentionally connected to the original object tree.
- Migrate fixed--name-field management tool from RooAbsReal to RooAbsArg. Used to accomplish regular
formatting in RooAbsCollection::printStream.
- Add concept of transient boolean attributes that are not tranferred on copy construction. Mostly useful
for debugging.
- Extend leafNodeServerList and treeNodeServerList to distinguish to types of leaf-nodes: strict leaf modes
in the sense of the client-server tree structure and 'physical' leaf nodes that do not recurse into
nodes that have isDerived()==kFalse. The latter corresponds to the original concept of leaf nodes / variables,
which the former mode, a new addition, explicitly exposes any shape servers contained in parameterized
ranges of variables.
- Fix logic error in recursiveServerRedirect: do not recurse into nodes that are in the replacement list themselves.
- Fix bug in printCompactTree(): value/shape clients were not always properly indicated.
- Add getAllConstraints() method that finds all RooProdPdfs in expression trees and harvest constraints from all
of these from the getConstraint() method
o RooAbsPdf
- Implement new evaluation error logging mechanism for negative p.d.f values and zero normalization integrals
- Add Constrain(const RooArgSet& pars) and ExternalConstraints(const RooArgSet& pdfs) arguments to fitTo() method.
The Constrain() method retrieves any constraints p.d.f. on parameters multiplied in any RooProdPdf in the normal
p.d.f expression and adds those to the likelihood that is minimized. Only constraints on the listed parameters
will be picked up. Multiple constraints per parameter may exist. The ExternalConstrains() argument implements
similar functionality except that provided external constraint p.d.f.s are added rather than internal constraints.
- Fix potentially fatal bug in print statement in getContext()
- Add new method createCdf() to create a cumulative distribution function from given p.d.f. Given a set of observables x,
the returned c.d.f is implemented in terms of a RooRealIntegral of p.d.f(x') over a parameterized range from [ 0 - x ].
o Roo1DIntegrator
- Improve error message
o RooRealIntegral
- Fix bug in calculation of shape dependencies on observables.
- Add handling of dependencies of integral value on values of objects representing parameterized ranges of
integrated observables.
o RooMCStudy
- Add Constrain(const RooArgSet& pars) and ExternalConstraints(const RooArgSet& pdfs) arguments to constructor.
In addition to passing these arguments to the fitTo() call of the fit stage, modify event generation as
follows: instead of sampling events from 'static' generator p.d.f, sample value of constrained parameters
from joint constraints p.d.f and sample observables at those parameter settings. Save the generator parameters
for each toy as these change per toy. Change the pull calculation such that it uses the per-event truth values
rather than the per-study truth value if constraints are used.
o RooAddition
- Fix bug in evaluate() related to persistence
o RooMinuit
- Enable/disable new evaluation error logging mechanism prior to and just after each MINUIT call.
- Print logged error messages, if any, in glue function
o RooProjectedPdf
- Fix important bug: normalization set should always include integration set for each configuration
o RooGlobalFunc
- Add definition of Scaling(),Constrain() and ExternalConstraints() helper functions
o RooUniformBinning
- Remove dedicated print function as it output is identical to that of the generic print function in RooAbsBinningx
o RooAbsBinning
- Add virtual methods isParameterized(),lowBound() and highBound() to be to detect and analyze parameterized binnings
through abstract interface
- Add isShareable() method to be able to separate shareable and non-shareable binnings in RooRealVar.
- Add insertHook() and removeHook() function to allow connection of possible proxies present in binning to
owning RooAbsArg.
o RooWorkspace
- Improve code import facility by introducing a class->file mapping step in the CodeStore to correctly handle cases where
multiple classes are defined in a single file.
- Add check that TClass interface actually yields file names.
- Only require default constructor to be present for non-abstract classes. It should be there for abstract classes as
well but current TClass::HasDefaultConstructor() method will not tell us.
o RooTreeData
- Improve renameVariable() method to not only rename the RooAbsArg branch buffer but also any TTree branches involved as well.
While the tree branch names are generally invisible to the user, having branch names that are different from branch buffer names
may cause branch naming conflicts in merge() that are not detectable as branch buffer naming conflicts.
o RooParamBinning
- New class implementing binning with low and high points defined by external RooAbsReal objects
o RooConstrainSum
- Helper class for RooAbsPdf to represent likelihood of collection of constraint p.d.f.s.
==== Date: Fri Mar 28 10:04:57 2008 =====
o RooRecursiveFraction
- Helper function for RooAddPdf that calculates recursive fraction
f1*(1-f2)*(1-f3) from a given set of plain fractions
o RooAddPdf
- Add flag to ctor to optionally interpret fractions as recursive fractions.
If activated it constructs the recursive fractions using RooRecursiveFraction
from the original fractions
o LinkDef3.h, Module.mk
- Add new class RooRecursiveFraction
==== Date: Tue Apr 1 22:42:19 2008 ====
o RooDataWeightedAverage
- New implementation of RooAbsOptTestStatistics that calculates data weighted
average of any RooAbsReal. This class serves as successor of RooDataProjBinding
that no longer complies with new optimization scheme.
o RooRealBinding
- Implement name() function for more useful error messaging in integration
o RooChi2Var,RooNLLVar
- Follow changes in base class
o RooAbsReal
- In plotOn() support binning flag in ProjWData(). Reimplement data-weighted projections
using new RooDataWeightedAverage class instead of RooDataProjBinding which does not
work with new generic function optimization scheme.
- Add support for NumCPU() argument
in plotOn() to facilitate multi-processor calculation of projections. Extend NumCPU()
argument to pass interleaving option in MP splitting mode of RooAbsTestStatistic
- Move fixAddCoefNormalization() and fixAddCoefRange() from RooAbsPdf to RooAbsReal
o RooAbsTestStatistic
- Generalize functionality: allow RooAbsReals as input arguments instead of RooAbsPdfs only.
Also add virtual globalNormalization() function that allows to apply a global normalization
term after combinedValue() operation to facilitate functionality of RooDataWeightedAverage.
- Add option to split data in multiprocessor mode in interleave mode instead of in bulk mode.
Interleave mode is useful for parallel processing of histogram data where bulk partitions
may not contain equal amount of non-zero data points leading to non-optimal load balancing
between processes.
o RooAbsPdf
- Move fixAddCoefRange() and fixAddCoefNormalization to RooAbsReal to support operation of
new generalized RooAbsTestStatistic
o RooIntegrator1D
- Use name() of RooAbsFunc() to clarify warning and error messages.
o RooRealIntegral
- Rename _operMode to _intOperMode to avoid shadowing of equally named data member in RooAbsArg
- Fix bug in recursive printing
o RooSetProxy
- Fix bug in print()

=== Date: Tue Apr 15 17:57:32 2008 ===
o RooMsgService
- Add option to prefix streamed messages with process ID to simplify
debugging of parallel fits
o RooAbsProxy
- Add optional addContents flag to print()
o RooArgProxy, RooSetProxy, RooListProxy
- Implement addContents flag in print()
o RooAbsReal
- Reimplement stack of logged error messages in terms of custom EvalError class.
A separate list<EvalError> is now kept for each object that reports an error.
In addition to the given error message a record is constructed of the proxy
values at the time of reporting.
- In printEvalErrors() add option to restrict number of reported items per node.
If number is zero, only number of errors per node is shown (without details)
o RooRealMPFE
- Adjust ReportErrors message to changes EvalError implementation in RooAbsReal.
- Make sure to synchronize remote error logging state with state of parent process
before each evaluate()
o RooRealVar
- Move printing of error from printValue() to printExtras()
o RooNLLVar
- Fix bug in setting of interleave parameter of base class in certain ctors
o RooAbsPdf
- Improve passing of eval error messsages by make separate messages for NaN
and negative values and including details in the error message
- Add PrintEvalError(Int_t nErr) option to fitTo() to control new eval error
message control system
- Int printValue show both value (raw from evaluate()) as well as most recently
used normalization value (if available)
o RooMinuit
- Interface new eval error logging control by adding setPrintEvalErrors(Int_t numEvalErrors)
=== Date: Thu Apr 24 15:11:59 2008 ===

o RooAbsCache
- New abstract base class for cache objects associated with RooAbsArgs.
Caches register themselves with the owning RooAbsArg and propagate
all necessary state changes and meta information to objects in the cache
o RooCacheManager
- Concrete template implementation of RooAbsCache with an interface
and functionality styled after RooNormListManager. The template class
provide no special handling for cache contents that includes RooAbsArg
objects and does not forward hook calls. It is thus mostly intended
to cache basic types indexed on a normalization/integration configuration
o RooObjCacheManager
- Class derived from RooCacheManager<RooAbsCacheElement> that implements
all proper call forwarding and handling of state and other meta information
to RooAbsArg objects embedded in the cache elements. To facilitate this
functionality the RooAbsCacheElement defines a pure virtual method
containedArgs() that must be implemented to expose its contents to
the cache manager. The default behavior on a serverRedirect hook is
to sterilize the cache. OperMode changes are not forwarded by default
to the cache contents as cached objects do not necessarily have the
same operation mode (e.g. if the cache contains an integral of its owner).
Any calls to optimizeCacheMode(), printCompactTreeHook(), and findConstantNodes()
are forwarded. Moreover, optimizeCacheMode() calls are remembered and
any objects inserted in the cache after such a call was received will be
optimized upon insertion in the cache
o RooAbsCacheElement
- Abstract base class for objects to be managed by RooObjCacheManager. Each
object must in addition to its payload implement the containedArgs()
member function that exposes the RooAbsArg object content to the manager
for processing. The argument passed to containedArgs() indicates the use
case for the returned list of objects, allowing the cache payload to
return different lists depending upon use. This is for most applications
not required.
o RooAbsCachedPdf
- Abstract base class derived from RooAbsPdf for p.d.f.s that implement
value caching in a grid over the entire domain of the observables.
The base class implements the overall caching logistics and manages
the RooDataHists and RooHistPdfs that respresent the cached contents.
Derived classes must inputBaseName() defined a unique name prefix for
all cache objects, actualObservales() and actualParameters() to
determined the actual observables and parameters given a set of
available observables and fillCacheObject() which should fill the
RooDataHist cache for a given obs/params configuration with the
p.d.fs values.
o RooAbsSelfCachedPdf
- Abstract base class derived from RooAbsCachedPdf that implements
all of the required logistics in RooCachedPdf and only require
derived classes from RooAbsSelfCachedPdf to implement evaluate().
Any class derived from RooAbsPdf can thus be trivially switched
to derived from RooAbsSelfCachedPdf and gain the caching functionality.
o RooCachedPdf
- Concrete class derived from RooAbsCachedPdf that implements
the caching of an externally provided p.d.f in the constructor.
o RooFFTConvPdf
- Concrete class derived from RooAbsCachedPdf that implement generic
numeric convolution of two input p.d.f.s using FFT technique
and convolution theorem. Actual FFTs are calculated by FFTW
through TVirtualFFT interface in ROOT. Present implementation only supports
convolution in one dimension, but this will be extended later
as there are no fundamental limitations in RooAbsCachedPdf nor FFTW.
o RooHistPdf
- Moved from RooFit to RooFitCore because it is used by caching classes
o RooProdPdf
- Use new RooObjCacheManager to store partial objects
- Fix memory leak (already patched in 15.0.14h)
o RooDataHist
- Use new RooCacheManager template to cache partial bin volumes
- Add new set(),setAllWeights() method to update current weight and all weights
respectively, for use in cached p.d.f.s
- Add sliceIterator() that iterates over all bins in a lower dimensional
slice of the dataset
o RooDataHistSliceIter
- Class derived from TIterator that implements the iteration
over a slice in a reduced number of dimensions in a RooDataHist
o RooMsgService
- Speed up processing of debug streams in cases where no debug streams are active
- add macros series oocoutX and oocxcoutX that allow to associate message with
a different object than *this
o RooRealBinding
- Interface new setValue method that allows value to be set outside default
domain, but inside given alternate named range. For use in numeric integrator
bindings
o RooAbsRealLValue
- Add new inRange() method with range name specifier to check against chosen
range instead of default range
o RooCmdConfig
- Fix dangling return pointer problem in decodeStringOnTheFly() method
o RooNameSet
- Fix bug in refoll()
o RooChi2Var, RooNLLVar
- Add processing of AddCoefRange() named argument
o RooConvCoefVar
- Hold p.d.f in proxy without value/shape state propagation to obtain
correct dependency of RooConvCoefVar through separate set proxy
with parameters that do have state propagation
- In getAnalyticalIntegral() ask for integration coefficient specific
to coefficient (following interface change in RooAbsAnaConv)
o RooEfficiency
- Follow interface change in RooCategoryProxy
o RooAbsAnaConvPdf
- Use new RooObjCacheManager to hold normalization and coefficient representations
- Extend getCoefAnalyticalIntegral() interface so that each coefficient
can have a separate integration configuration
- Modify makeCoefVars() such that it constructs the RooConvCoefVars with
actual dependents for each coefficients, rather than inserting dependencies
of any of the coefficients in each coefficient. This logic requires support
from the implementation class that is interface through a new member function
coefVars()
o RooAbsReal
- Add Boolean data member treeVar that indicates is value buffer is also
branch buffer of a tree. This information is already present in the RooAbsReal
but is relatively expensive to retrieve and is always needed in the inner
loop of data set operations. This extra member significantly speeds up operations
- Remove superfluous _norm[] token in name returned by integralNameSuffix() if
no normalization set is supplied.
- Add a fillDataHist() method that fills a given RooDataHist with a sampling
of the given function. Added for support of caching p.d.f.s
- Downgrading warning on non-dependent projection variables in plotOn() to
a debug level message
- Remove function optimizeDirty(),doConstOpt(),undoConstOpt(),findCacheableBranches()
findUnusedDatasetVariables() and findRedundantCacheServers() as part of reorganization
of optimization functionality.
o RooAbsCollection
- Use iterator semantics instead of vector semantics to process RooLinkedList
contents in assignment operator
- Add utility function contentsString() returning stl string with names
of contents
o RooAddPdf
- Rewrite cache management using new RooObjCacheManager that holds projection
integrals, range integrals and supplemental normalization lists
o RooAbsOptGoodnessOfFit
- Improve handling of normalization ranges and reference ranges for test statistics
containing RooAddPdfs. New named argument in fitTo() and RooNllVar::ctor() pass
reference range for fractions in RooAddPdf components that do not have an explicit
fixed definition already. Name all normalization ranges explicitly after the
subrange to which the're applied to avoid name clashes and conflicts if multiple
normalization ranges are involved.
- Rewrite informational messages through RooMsgService
- Implement new constOptimizeTestStatistic() function that signals all test statistic
components of a RooAbsArg expression tree to perform their constant term optimization
- Implement new optimizeCaching() driver function that changes default lazy-evaluation-with-caching
scheme to test statistic scheme where only parameters objects propagate state changes and
where all components that depend directly or indirectly on observables have lazy evaluation
disabled. Changes to p.d.f objects are delegated to RooAbsPdf::optimizeCacheMode(). Changes
to dataset are delegated to RooAbsData::optimizeReadingWithCaching()
- Implement new optimizeConstantTerms() function that is back end for constOptimizeTestStatistic
implementation.
o RooAICRegistry, RooNormSetCache
- Remove tracking of allocation cycles of RooArgSets as this scheme is superseded by
memory pool mechanism for RooArgSet allocation
o RooMappedCategory
- Follow interface change in RooCategoryProxy.
o RooRealMPFE
- Follow reorganization of optimization functionality: implement new constOptimizeTestStatistic
function for forwarding to slave processes.
o RooRealVar
- Add new setVal() function with range name to facilite setting of values that are outside
default range, but inside specified alternate range. Needed for numeric integration and
certain RooAddPdf coefficient projection.
o RooAbsArg
- Make state management functions public [is/set][Value/ShapeDirty](), setOperMode90
- Add static _flipAClean boolean to support setACleanAdirty() static method.
- Implement mechanism for registration of cache objects with base class RooAbsCache.
Forward all calls to operModeHook(), redirectServersHook(), optimizeCacheMode()
and printCompactTreeHook() to all caches for further processing
- Define constOptimize() function and provide default implementation that forwards
to all servers
- Implement optimizeCacheMode() function that puts expression tree in optimized
caching for test-statistics operations (only cache/lazy evaluate nodes that
do not (indirectly) depend on observables
- Implement findConstantNodes() function that identifies all nodes that depend
exclusively on constant observables and >0 observables that are eligible
for precalculation and caching in test statistics operations by
RooAbsOptTestStatistic::optimizeConstantTerms()
- Define constOptimizeTestStatistics that signal an expression tree that any
embedded test statistic objects should perform their constant term optimization.
Default implementation in RooAbsArg forwards call to all servers.
o RooAbsPdf
- Use new RooObjCacheManager to manage normalization integrals cache.
- Process new SumCoefRange() option in fitTo() that sets the coeffient
interpretation range for all embedded RooAddPdf objects of which
the interpretation range was not explicitly set
- Extend interface of fixAddCoefNormalizationSet(): add extra argument
that controls if AddCoef normalization set are forcibly overruled
for objects that already have an explicit range setting.
o RooRealIntegral
- Add some informational messaging through RooMsgService, rewrite existing ones
- Speed up numeric summations by precreating the involved RooSuperCategory
in the ctor rather than in evaluate().
- Fix bug in dependency insertion: explicitly require servers to be value
server to avoid pulling in fake dependents.
- Remove obsolete data members
- Implement new setACleanADirty() function that atomically flips state of
all AClean objects to ADirty for the duration of the integration step.
Replaces the much more expensive prepareACleanFunc() that did this
only for the objects involved.
- Process factorizing terms in integral only if the list is not empty
- Process Jacobian terms in integral only if the list is not empty
o RooAddGenContext
- Adapt to cache management chanches in RooAddPdf
o RooNumIntFactory
- Use STL classes for internal memory management
o RooSetProxyy

the newly introduced RooFFTConvPdf
o RooMinuit
- Follow reorganization of optimization functionality
o RooProjectedPdf
- Store projection using new RooObjCacheManager
o RooGlobalFunc
- Add RooFit::SumCoefRange() named argument for RooAbsPdf::fitTo()
and RooNLLVar::ctor() and RooChi2Var::ctor()
o RooClassFactory
- Extend existing makePdf(),makeFunction and makeClass() functions
to also accept RooAbsCategory arguments, to accept an optional string
inserted as the return value expression inserted in the
evaluate() method of the class created, as well as as option string
specifying one or more analytical integrations of the given function
expression that will be advertised in the generated getAnalyticalIntegral()
code and implemented in the generated analyticalIntegral() code
- Add makeAndCompileFunction() and makeAndCompilePdf methods that
generate the code and immediate compile it through ROOTs ACliC interface.
These functions have a simpler interface because the list of arguments
of the function to be created can be specified as a const RooArgSet&
rather than a string with a list of names, thus making it easier
for on-the-fly definition of compiled objects.
- Add defineFunction() and definePdf() methods define and compile
a function/pdf using the above functions and immediately instantiate
an object of the given type passing the specified RooArgSet arguments
to the constructor of the object. These functions make a compiled
equivalent of RooFormulaVar based on the TFormula interpreter, i.e.
RooAbsReal* f = new RooFormulaVar("f","D(1-2w)",RooArgSet(D,w)) ;
becomes
RooAbsReal* f = RooClassFactory::defineFunction("f","D(1-2w)",RooArgSet(D,w)) ;
o RooAbsCategory
- Add Boolean data member treeVar that indicates is value buffer is also
branch buffer of a tree. This information is already present in the RooAbsReal
but is relatively expensive to retrieve and is always needed in the inner
loop of data set operations. This extra member significantly speeds up operations
- Construct explit clean name for TBranch name if node is cached, equivalent
to what is done in RooAbsReal. Needed because new constOptimizer can also
cache RooAbsCategory objects
o RooArgSet
- Implement operator new() and operator delete() to implement memory pool scheme
for RooArgSets. The goal of this implementation is to insure that two RooArgSet
pointers are _never_ the same. This allows to RooNormSet cache manager to safely
and quickly index integration and normalization configurations by evaluating
the contents of a RooArgSet only the first time it sees it.
o RooSimultaneous
- Implement caching of partial integrals using new RooObjCacheManager
- Following interface change in RooCategoryProxy ;
o RooAbsData
- Defined pure virtual methods optimizeReadingWithCache() and allClientsCached()
o RooTreeData
- Implement optimizeReadingWithCache() which determines given a p.d.f to be
evaluated and a list of the nodes that are cached for it, which observables
in the dataset are no longer required because they are either not an observable
of the p.d.f, or they exclusively feed nodes that are cached. Reading of these
observables is disabled through SetBranchStatus().
- Move allClientsCached() utility function here from RooAbsReal.
o RooCategoryProxy
- Remove const char*() conversion operator in favor of a const char* label() method
to remove possibly ambiguities in C++ math expressions involving category proxies.
o LinkDef3.h
- Add newly defined classes

introduced by the BaBar IOstream migration utilities
o Several class
- Initializion order changes, removal of unused variables,
addition of missing return statements to make all code
compile cleanly with '-Wall -Wno-parentheses'
o RooAbsFunc
- Make resetNumCall() const
o RooAbsIntegrator
- Add calculate() method that wrape integral() between
profiling code the track the number of integrand
function calls
o RooIntegrator1D,RooImproperIntegrator1D,RooSegmentedIntegrator1D,
RooSegmentedIntegrator2D,RooMCIntegrator
- Change interface to take RooNumIntConfig class instead
of now deprecated RooIntegratorConfig class
- Add member function that advertise capability of the integrator:
canIntegrate1D,2D,ND,OpenEnded()
o RooAbsReal
- Change normalization integral management classes
(createIntegral(), (set)defaultIntegratorConfig(),
(set)specialIntegratorConfig()) to work with new
RooNumIntConfig class.
o RooArgSet
- Add new convenience functions get/setRealValue(),
get/setCatLabel/Index(), get/setStringValue() to
manage common content of RooArgSet.
o RooConvCoefVar, RooConvGenContext
- Support class name change RooConvolutedPdf -> RooAbsAnaConfPdf
o RooCustomizer
- Add function setCloneBrancSet() that allows to specify
an external set that takes ownership of the cloned branch
nodes so that customized objects can live beyond the lifetime
of the RooCustomizer instance
o RooImproperIntegrator1D
- Add code to handle limit scenario changes (closed to open ended
and vice versa) on the fly
o RooIntegrator1D
- Add fixSteps option to terminate integral calculation after
fixed number of steps w/o extrapolation. This is more robust
for certain types of integrals
o RooRealIntegral
- Change interface to take RooNumIntConfig class instead of
RooIntegratorConfig class
- Delegate instantiation of numeric integration engines to
new class RooNumIntFactory
o RooNumIntConfig
- New class to store configuration of numeric integator engines.
This class has a brief common section with common properties
like absolute and relative precision convergence criteria,
and a section with implementation specific details for each
engine in the form of a RooArgSet. The default settings for
each existing engine are automatically added to the defaultConfig()
instance during run-time initialization
o RooNumIntFactory
- Factory class for numeric integration engines. Each existing
integrator engine automatically registers with the factory
stating its capabilities (1D,2D,ND / Open-ended). The
createIntegrator() function instantiates an integrator
appropriate for a given problem. In case more than one
integration engine can solve the given problem the (user
changable) information in the RooNumIntConfig passed along
with the call is used.
o RooGaussKronrodIntegrator1D
- New integrator engine based on Gaussian quadrature techniques.
This implementation, taken from GSL 1.5 implements the Gauss-Kronrod
techniques where the error on the integral is take from the difference
between the Gauss and Kronrod techniques. These techniques share common
sampling points allowing to calculate the error without additional cost.
This integrator applies the 10,21,43, and 87 point rules in succession
until the desired accuracy is reached. Open-ended integrals are
automatically handled through a x -> 1/x coordinate transformation
o RooAdaptiveGaussKronrodIntegrator1D
- New integrator engine based on Gaussian quadrature techniques.
This implementation, taken from GSL 1.5 implements the Gauss-Kronrod
techniques where the error on the integral is take from the difference
between the Gauss and Kronrod techniques. These techniques share common
sampling points allowing to calculate the error without additional cost.
This integrator applies the 10,21,31,41,51 or 61 point rule and
recursively subdivides the integration domain until the desired accuracy
is reached. For integrands with integrable singulaties the Wynn epsilon
rule can be selected to speed up the converges of these integrals. Open
ended integrals are automatically handles through a x -> 1/x
coordinate transformation
o RooNumConvPdf
- New operator PDF class that implements numeric convolution of
any two PDFs. The calculation of the convolution integrand
is implemented in the auxiliary class RooConvIntegrandBinding,
which in turn can be integrated with any 1-D numeric integration
engine. The default integration method for convolution integrals
is the adaptive Gauss-Kronrod method, which appears to give the
most stable results. By default the integration is performed
from -inf to +inf, but can optionally be restricted to a sliding
window using the setConvolutionWindow class, useful for relatively
narrow resolution PDFs.
o RooAbsAnaConvPdf
- New name of RooConvolutedPdf to clearly distinguish its functionality
from RooNumConvPdf

- Minor modification in verbose dirty state messaging
o RooAbsCategory
- Recognize integer branches in non-RooDataSet trees
and attach to those in a special mode (similar to how
single precision flaots are treated in RooAbsReal)
- Modify copyCache() to recognize when copying from a
special mode RooAbsCategory. In such cases the index
is copied from the source and the label is then restored
from the destinations state list
o RooAbsCollection,RooSetProxy,RooListProxy
- Add option to remove() to match arg(s) to be removed
only by name and not by pointer in addition
o RooAbsPdf
- Modify syncNormalization() so that it accepts LValue branch
nodes in the normalization set specification.
o RooAbsReal
- Modify createProjection() to properly construct projections
with LValue dependents
- Modify plotOn() to allow plotting of LValues
o RooArgProxy,RooRealProxy,RooCategoryProxy
- Add option in ctor for proxy to take ownership of proxied object
o RooCurve
- Modify ctor to allow plotting of LValues
o RooLinearVar
- Set initial value of plot range and bins from
those of the dependent
o RooRealIntegral
- Some adjustments to LValue substitution algorithm in ctor
o RooTreeData
- Modify all ctors to use new createTree() member function
to instantiate the TTree. createTree() will cd to memory
directory during TTree ctor so that RooDataSet tree will
be memory resident regardless of the current directory
- Warn user when loading invalid values from non-RDS TTrees

o RooRealIntegral
- Introduce LValue detection in tree structure analysis.
An iterative algorithm determines if there is a non-empty
set of LValue branch nodes suitable for analytical integration
and a set of leaf nodes to be integrated, that exclusively
relate to each other (i.e. set of leafs serves only exactly one
element of the set of LV branches; LV branches only depend on
that set of leafs). If such sets can be found, the LV branches
are substituted for the leafs in the list of dependents to be
integrated.
Actual use of these LV branches in analytical integration
still depends on capability of integrated function. If not,
numerical integration will be performed on LValue.
Caveats: currently the algorithm does not optimize scenarios
like 'server a -> LVnodes (A,B), server b ->LVnodes(A,B), i.e.
multi-dimensional coordinate rotations. Although the
iterative algorithm could easily identify the potential replacement
(a,b) -> (A,B), such substitutions would have to be reviewed
after interaction with the integrated functions' getAnalyticalIntl().
If it turns out the function can only analytically integrate A or B
but not both, the entire substitution would have to be backed out
as an integral over (A,a,b) or (B,a,b) has a redundant dimension.
o RooArgSet,RooArgList
- Add ctor from TCollection. RooArgSet ctor will skips and warns about
eventual duplicate entries by name.
o RooAbsPdf
- Remove obsolete fitTo(TH1*,...) dummy entry point.
o RooLinearVar
- Remove debug print statement

Binned data reorganization
--------------------------
o RooAbsArg,RooAbsCategory,RooAbsReal,RooAbsRealLValue,RooAbsCategoryLValue,RooAbsLValue,RooRealVar
- Introduce the concept of 'fit bins' for the purpose of binned fits
So far we have been abusing the plot bins for this purpose but this
will ultimately lead to confusion
RooAbsLValue now defines 5 abstract methods to access the fit bin interface
setFitBin(), getFitBin(), numFitBins(), getFitBinWidth(), createFitBinIterator()
which are implemented in RooAbsCategoryLValue and RooAbsRealLValue
RooRealVar holds the fitBins data member.
o RooDataHist
- Change to use fit bins and range instead of plot bins and range for
binning a dataset
- Add new sum() methods implementing full and partial summation of
of the dataset contents, optionally accounting for bin volume correction
o RooHistPdf
- New PDF constructed from a RooDataHist implements n-dimensional
PDFs constructed from an equivalent histogram. All dimensions can
be either real of discrete
- All partial and full integrations are implemented using the new
RooDataHist::sum() methods.
Plotting reorganization (part 1)
--------------------------------
o RooPlot,RooHist,RooCurve,RooPlotable
- Store the two components of the normalization #events and binWidth
seperately
- Replace getFitRangeNorm() method with getFitRangeNEvt() and getFitRangeBinW()
methods
- Adapt updateFitRangeNorm() to store components of normalization separately
o RooAbsReal ( & RooSimultaneous)
- Add extra enum to plotOn() indicating interpretation of given scalefactor
Raw -> Apply scale factor without any other adjustments
Relative -> Apply scale factor after default normalization adjustment (old implementation)
NumEvent -> Interpret scale factor as number of events to normalize to
For RooAbsReals that are not a RooAbsPdf, the Raw procedure is always applied
Some more reorganization will follow in this area
o RooFormulaVar
- Take out dummy analytical integration definition now that plotOn will do the
right thing by default
Misc. fixes
-----------
o RooAbPdf
- Fix normalization bug in analytical integration by introducing overloaded
analyticalIntegralWN, which returns analyticalIntegral()/getNorm()
instead of just analyticalIntegral()
o RooAddPdf
- Eliminate now obsolete addPdf() and addLastPdf() member functions

o All RooAbsArg derived classes
- Change clone() to clone(const char* newname=0) to facilitate cloning with alternate names.
o RooAbsArg
- Add another layer to link management: operMode. If operMode=auto, all behaves
as before. If operMode=AClean, the arg assumes the cache is always clean and
getValueDirty() will always return false. If operMode=ADirty, the arg assumes
the cache is always dirty and isValueDirty will always return true.
The ADirty and AClean modes are used by the optimizer in the fit context
to shut down link management (and save time) for cases where the arg is
always dirty after a dirty state propagation from one of the dependents.
The AClean mode is used similarly for args that are cached in the dataset
The setOperMode() member is protected as care should be taken in switching modes.
It is the callers responsability to ensure that the claimed state (especially
in case of AClean) is indeed correct.
- Split setValueDirty(Bool_t flag) in setValueDirty() and clearValueDirty().
The latter is trivial and can be inlined to save time.
- redirectServers() now has an optional nameChange flag that allows to reconnect
to servers with different names. If the option is enabled, a link will be reconnected
to the server with a 'ORIGNAME:<servername>' attribute instead of a server with <servername>
This feature is used by RooPdfCustomizer.
- Added recursive printDirty() member that listed dirty state of arg and all its servers.
- Add sorting capability by implementing IsSortable() and CompareTo() members.
Sorting will result in alphabetical ordering by object name.
o RooAbsCategory
- Change tree attachement: store both label and index fields in tree instead of
just the index field. Looking up the corresponding label turns out to be rather
expensive, especially if many state are defined.
- The postTreeLoadHook() mechanism that formerly implemented the index lookup
has been abandoned completely (save 1 virtual function call per data set load).
o RooAbsPdf
- Change function call structure of eval tracing a bit to reduce the number
of calls per trace from virtual calls to 1 concrete call.
- In syncNormalization, if the data sets are different, first check if they
also have a different contents before processing the change. (Save multiple
identical normalization calculations for cases were a resolution model is
shared by >1 RooConvolutedPdf. (WVE Caveat: this has some problems: code will
die if cached data set is deleted before pdf. Will fix this soon)
Install pre- and postSyncNormalizationHook functions that can be used to customize
the call. Used by RooConvolutedPdf to create/update dummy data sets used to
push down partial integrations to the convolution integrals.
- Move nLogLikelihood to RooFitContext
o RooAbsReal
- in attachToTree(), mangle name of object in tree to exclude math symbols that
are interpreted by root in certain circumstances
o RooAddModel
- Store coef and proxy iterators in class instead of creating them on the fly each
time in evaluate()
- Release ownership of proxied resolution models in the copy constructor. If the
AddModel is copied, the proxied components will be owned by the list created
by RooArgSet::snapshot().
- Include name of AddModel owner in component resolution model to avoid multiple
identically named object in certain PDF configurations
- Export 'master list' of combined normalization leaf node servers of all components.
The convolutedPdf needs this for it's own dependency calculation
o RooArgSet
- Add silent option to remove()
o RooCatType
- Store name in char[] instead of in TNamed::fName (a TString) so that
the name can be attached to a Tree. (A TString is not a TObject)
o RooConvolutedPdf
- Push integration of all dependents that do not overlap with the coefficients
to the convolution integrals, instead of just the convolution variable
o RooDataSet
- Add new constructor that allows to specify the cut as a RooFormulaVar object
instead of a string. This allows to cut on function arguments that are not
part of the data set
- Allow to switch off dirty state propagation after a row-load operation
(can be used in certain optimization scenarios)
o RooFitContext
- Add option to not clone either dataset or pdf on construction
- Remove non-RooRealVar parameters from master parameter list to prevent that
MINUIT chokes on them
- Sort minuit parameter list alphabetically
- Add cache optimization option, which shuts down all link management for the
all pdf value components (not normalization). This can save a significant amount
of time, especially for very complex PDFs as the number dirty propagations scales
with the square of the number of nodes. Use newly introduces AClean and ADirty
modes to ensure proper evaluation of PDF nodes
- Add option to execute migrad with 'strategy 0', which skips the evaluation of
the error matrix. (Saves time if you do that later with HESSE anyway)
- Move nLoglikelihood() function from RooAbsPdf to here.
- Improve readability of messages in fitting in log-mode: print on screen only value
and name of parameters that change instead of dumping all their values all the time.
The old format has been retained in the log file, to allow automated processing of such files.
o RooFormulaVar
- Also update _origList on a serverRedirect
- Export ok() function of RooFormula (indicates if expression compiled ok)
o RooMath
- Add fast, interpolated, complex error function. Upon first use separate lookup tables
are filled for the im and re part of the complex error function. New functions will
do a 2nd or 3rd order 2D interpolation (depending on z) of the lookup table for either
the re part, the im part or both. Precision is better that 1e-6 in ~99% of covered
phase space. Imprecise regions are in problematic part of cErf where giant fluctuations
occur. Typical likelihood calculated with interpolated cErf agrees in the first 10
significant digits. Interpolation function is ~3.5 times faster than original CWERF
implementation, when only 1 component (im/re) of cErf is needed (most cases).
Interpolation function taken from Numerical Recipes and further optimized for
fixed grid assumption
o RooMappedCategory
- Clone also MapCatEntries in RooMappedCategory copy ctor
o RooProdPdf
- Store coef and proxy iterators in class, instead of instantiating them on the fly
in evaluate()
- Add optional cutoff parameter. If running PDF product goes below cutoff, product
calculation is terminated (default value=0, very small values like 1e-15 can be
benificial in case of wide window calculations a Gaussian + something flattish)
o RooRealIntegral
- Allow and perform integration over variables that input function doesn't depend
on (multiply integral by product of ranges of such variables)
o RooResolutionModel
- In convolution(): append name of owner to convolution, to avoid non-identical
convolutions with the same name in certain PDF configurations
- Forward redirectServers to basis function
o RooSimultaneous
- Overload fitTo() to create a RooSimFitContext instead of a RooFitContext
which allows certain additional optimizations specific to RooSimultaneous
- Normalize by the number of registered PDFs instead of the number of types
defined by the index category (allows to to partial fits)
o RooStreamParser
- Take '}' and ';' out of the default punctuation list so that RooSuperCategory
state names do not get broken up into multiple tokens
o RooThresholdCategory
- New category class that applies a series of thresholds on a RooRealVar to
define its state.
o RooThreshEntry
- Support class for RooThresholdCategory
o RooPdfCustomizer
- Utility class that serves a factory to build multiple PDFs from a single prototype
that have slightly different leaf nodes.
The class takes a proto type and a master index category in the constructor.
A series of splitting rules determines how given leaf nodes are to be 'split'
over the master index category or a subset of the master index (in case the master
index is a RooSuperCategory)
The instiated 'split' leaf nodes are put in an argset referenced in the constructor.
and the owner of the argset is responsible for deleting them (or passing them on
to another RooPdfCustomizer). The instantiated branch nodes are owned by the customizer.
o RooSimFitContext
- Specialized fit context, derived from RooFitContext, that optimizes the likelihood
calculation in case the top level pdf is a RooSimultaneous. The original data
set is broken into pieces, corresponding to a single state of the RooSimultaneous
index category and those data subsets are combined with the corresponding PDF branches
of the RooSimultaneous to form an array of regular RooFitContexts. The total likelihood
is calculated as the sum of the likelihoods from the array of fit contexts.
The NLL output from each subcontext is cached and only recalculated if a parameter
that the PDF of that subcontexts depends on, is changed.
This form of calculation is very efficient for fits where the correlation matrix has
a block diagonal form. The CPU time in RooSimFitContext scales (approximately) with
the number of elements in the block diagonal elements instead of with the total number
of elements.
o Nearly all classes
- A large number of minor bugs has been fixed and many functions
that are called very frequently have been inlined, made non-virtual or
have been eliminated, following the result of repeated profiler studies.
