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.

o PiecewiseInterpolation, RooAbsCachedReal, RooAbsCachedPdf
- Follow adjustment in RooCacheManager
o RooConvCoefVar, RooEffProd, RooResolutionModel, RooErrorVar, RooProjectedPdf, RooAbsHiddenReal
- Migrate to getValV
o RooProdPdf
- Follow adjustment in RooCacheManager
- Migrate to getValV
o RooVectorDataStore
- Various small fixes
- Allow storage of non-constant 'track-and-change' cache entries.
These are cached PDF nodes that are not constant, but need
to be recalculated when selected parameters change. A
RooChangeTracker data member is added to the vectors to
do this dependency checking, and recalculation (as needed)
is performed in method recalculateCache() to be called from
the test stat before looping of the data.
o RooAbsReal
- Introduce new non-virtual inline getVal() methods that handles
clean-cache state cases and delegates all other cases to a
virtual method getValV() that corresponds to the original
getVal() method
- Add 'ignore' more to eval error logging protocal
o RooAddPdf
- Follow adjustment in RooCacheManager
- Optimize control structure in evaluate() to be more efficient
(move conditional outside loop)
o RooAbsTestStatistic
- Add extra argument to constOptimizeTestStatistic to control
activation of track-and-change optimization
o RooRealMPFE
- Migrate to getValV()
- Add support for new track-and-change option argument in
transmission of const optimization request to servers
o RooRealVar
- Exploit new _fast flag of RooAbsReal to choose non-virtual
handling of getVal()
- Migrate to getValV() [ but still dummy ]
- Small fix in attachToVStore()
o RooNLLVar
- Add data member tracking first use
- After first use, trigger wiring of all caches in RooCacheManagers
to speed up trivial cache selection decisions (i.e those where
only a single cache entry exists)
- Add call to RooAbsDataStore::recalculateCache() to implement
track-and-change update prior to likelihood loop
o RooConstVar
- Migrate to getValV()
o RooAbsArg
- Eliminate flipACLean() protocol since no longer used
- Simplify method opermode() now that flipAClean is abandoned.
- In findConstantNodes() add support for change tracking
and include nodes with "ChangeTracking" atttribute in
list of constants. Mark all truly constant expressions
with attribute "ConstantExpression"
- Add extra argument to constOptimizeTestStatistic to control
activation of track-and-change optimization
- In printCompactTree() also print valueDirty state when in Auto mode
- Add method wireAllCaches() which propagates cache wiring request
to all registered cache nodes on all branches nodes
- Add transient data member with namereg pointer to string with
current object name. Overload SetName() and SetName() and title
to clear pointer whenever name changes.
o RooAbsPdf
- Migrate to getValV(). Eliminate handling of clean-cache cases
as this is now done in RooAbsReal::getVal()
- Disable use of RooAbsPdf::raiseEvalError() protocol as this
is now communicated through RooAbsReal::logEvalError()
o RooRealIntegral
- Migrate to getValV()
- Use setInhibitDirty() instead of flipAClean() in evaluate()
when performing numeric integrations
o RooTreeDataStore
- In cachArgs() add code to select only cache items with
label "ConstantExpression" as tree store is unable to
cache track-and-change items
o RooAbsCategory
- When printing also show index associated to label
o RooAbsOptTestStatistic
- Add extra argument to constOptimizeTestStatistic to control
activation of track-and-change optimization
- In optimizeConstantTerms() when trackChanges option is active
request change tracking for all component nodes of RooAddPdf
and RooRealSumPdf, unless these components are RooProdPdf/RooProducts
respectively in which case the components of these products are tracked
o RooRealProxy
- Use _fast attribute of RooAbsArg to directly return value cache
of RooAbsReals if that is allowed
o RooAbsCache
- Add virtual method wireCache()
o RooCacheManager
- Add new method getObj() that takes isetRangeName as 'const char*'
instead of 'const TNamed *' to be able to eliminate the conversion
when in wired mode
- Implement cache wiring - If at moment of the request only a single
cached entry exists - always return that one from here one.
o RooAbsDataStore
- Implement virtual method calculateCache()

operations
o RooBanner

o RooDataSet
- Introduce pool-based memory allocation scheme
- In ctor for composite datasets with Link() ensure that
order of observables is preserved to allow use of assignFast()
o RooRealSumPdf
- Use getNorm() in expectedEvents() rather than createIntegral()
o RooAbsCollection
- Do no allocate hash tables by default
- Introduce contents claim counter to counter 'foreign' ownership
claims of contents (needed for RooAbsOptTestStatistic::setData()
support)
- If collection is owning, only delete contents if claim count is also zero
- In snapshot() raise hash table threshold from 100 to 1000
o RooRefCountedList
- Disable hash tables by default
o RooStudyPackage
- Make study package own clone of incoming workspace
- Implement copy ctor
o RooAbsTestStatistic
- Implement 'master' setData() method. Forward to setDataSlave()
of self for monolithic likelihoods or forward data components
to likelihood components in case node is SimMaster. If data
is not fast-splittable, execute slow split.
o RooAbsData
- Implement 'live check' to be able to conclude if a given dataset
pointer points to a live or dead object
- Claim contents of _vars through new claim mechanism. Release
in dtor, allow _vars to delete contents if claim count is zero
- Add concept of owned component datasets to support fast-splitting
of dataset
- Add method canSplitFast() that indicate if fast split is available
(only possible if dataset was created as composite)
- Add method getSimData() that retrieves pointer to component
RooDataSet representation for a given index state
o RooObjCacheManager
- Add static mechanism that allows to deleted cached observables lists used for
cache optimization triggers to be deleted on a sterilize() action. This
is useful on toy studies with setData() operation, that would otherwise
collect very large lists of observable clones during the toy cycle.
o RooAbsPdf
- Set contraint term to ADirty to avoid synchronization problems when using
setData() in the likelihood
o RooAbsArg
- In clone operations set hash table threshold at 1000 nodes
- In getObservables() use pass-by-value iterators rather than heap iterators
to making this faster. Also make getObservables() non-virtual, as it is in
fact not overloaded in any subclass (anymore). Also remove looping over
branch nodes to call getObservablesHook() as no class implements method
anymore.
o RooAddition
- Implement a setData() method that forwards to its components. Allows transparent
operation of setData() on likelihood objects with constraint terms
o RooLinkedList
- Add method that returns iterator by value (simply forwards to similar implementation
in RooLinkedList)
o RooSimGenContext
- Move calculation of fraction table from ctor to dedicated updateFraction() method
- Before each generation sequence call updateFractions() so that multi-generation
sequence are robust against parameter changes between calls
- In createDataSet() always make a composite dataset if the index is present, as this
allows faster use in toymc operations
o RooAbsOptTestStatistic
- Initialize all variables in default ctor
- In dtor and ctor handle ownership of dataset observables, on which we put a claim
(i.e. we need to delete contents if the test statistics survives the dataset)
- Reimplement existing setData() as setDataSlave(), and add claim management on
dataset observables. When attached new data to function, request that object caches
clear full content in sterilize() operation to avoid buildup of cache objects in
long toy runs.
- In setData() adjust event count of test statistics, for correct functioning of extended
terms after update
o RooArgSet
- In ctor for list and a single object, only add object if not already in list
(is already checked, but new procedure preserves order of list elements in case
object was already present)
o LinkDef
- Add list<RooAbsData*> and map<string,RooAbsData*> to support streaming of composite datasets
o RooAbsStudy
- Implement clone method to support polymorphic array cloning
o RooAbsReal
- Add interface method setData()
o RooProfileLL
- When storing coordinates of absolute minimum, store only those that are non-constant.
Otherwise option to restart each minimization from known absmin may alter constant
parameters

o RooAbsSelfCachedPdf
- Declare embedded RooHistPdf as self-normalized to prevent
superfluous calculation of unit normalization
o RooDataHist
- Add new named argument ctor that can collate multiple
TH[123] into a N+1 dimensional RooDataHist which has
an extra RooCategory to distinguish the source, as
well as import single a TH[123] objects
- Add ctor that can do the same, but specified from
a map<string,TH1> specification.
- Add new importTH1Set(),importTH1() utility methods to implement
common functionaly of both new ctors
- Add adjustBinning() method that encapsulates the functionality
to adjust the RooDataHist observable binning to match that
of a given (imported) TH1, which was formerly contained in the ctor
- Speed up code in interpolateDim() by reducing number of required
lookups of the observable binning definition.
o RooParamBinning
- Add tree printout of boundary functions, if defined in verbose
printing mode
o RooMsgService
- Add special handling of PROGRESS message level: automatically
insert newline when switching from a PROGESS to another message level.
o RooPlot
- In verbose printing, add index number to printout of each contained
plotable object
o RooGenContext
- Fix for handling of observables with parameterized ranges
- Eliminate forgotted debug print statement
o RooAbsRealLValue
- Implement new binning interface methods that take binning reference
rather than binning name, for faster use in internal operations
- Implement new RooAbsLValue methods with RooAbsBinning pointers
o RooDataSet
- Add new named argument constructor that can generically handle imports
of TTrees, RooDataSet and can collate multiple RooDataSets into
a N+1 dimensional RooDataSet with an extra RooCategory that labels
the source dataset
o RooDLLSignificanceModule
- Tune some of the names of the produced output observables
o RooChi2Var
- Set the default error type to RooAbsData::SumW2
o RooCustomizer
- Modify the sterile build() routine to make the returned
head node own all the created components rather than
the customizer itself.
o RooAbsCategoryLValue
- In copyCache(), check that the value copied is in fact
valid for the destination.
o RooFitResult
- Tune the line widths of the objects created in plotOn()
when creating the error ellipse.
- Add a method correlationHist() that returns a 2D histogram
with the correlation matrix element values, which is labeled
with the parameter names.
o RooCurve
- Add explicit handling for evaluation errors that can occur
when sampling the function being represented. New constructor
arguments control how evaluation errors are logged to
RooMsgService, in similar style to RooMinuit, and control
how the drawn output value is affected (as calculated, or
substituted with a user controlled value).
o RooFFTConvPdf
- Add automated handling of FFT sampling windows of the 'physics'
pdf and the 'resolution' pdf. In the new setup the second pdf
is always assumed to be a 'resolution' pdf and its sampling window
is chosen symmetrically around zero, regardless of the definition
of the range of the convolution observable. The width of the sampling
window, and the number of sampling bins is still tied to the "cache"
binning defined in the convolution observable. Added setShift()
modifiers allow the user to manually control the sampling window
shifts on both pdf. The shift introduced by sampling a shifted
window of the resolution effect is correct a posteriori by
performing a compensating rotation of the final FFT buffer.
- Modify FFTCacheElem to cache a functional clone of both pdf
with optional shift transformations applied through a RooLinearVar
substitution of the original convolution observable. Instruct
caching RooDataHist not to forward dirty state propagation calls
and set sampling pdf clones to AlwaysDirty to increased operational
efficiency.
o RooChangeTracker

o RooRealSumPdf
- Implement component selection functionality in plotting as
is available for RooAddPdf
o RooEfficiency
- Implement analytical integral over acceptance category

of efficiency bins.
o RooAbsReal
- Make named argument version of fitTo() default method
when invoked with no arguments
- In fitTo(), if pdf is extendable and no explicit Extended() argument
is given, automatically included extended likelihood term
- In fitTo(), disable default running of MINOS when invoked without
arguments
- Move component selection functionality from RooAbsPdf
to here so that it also works for RooRealSumPdf, which
takes RooAbsReals as components rather than RooAbsPdf
- Add simplified createHistogram() method that takes
string with comma separated observable names and
three optional bin numbers.
- Add createHistogram() method that takes a list of
RooCmdArgs that can serve as backend for all user
interface methods.

inserts the curve at the bottom of a RooPlot stack.
o RooProduct
- Remove erroneous assert()
o RooAbsCollection
- In snapshot(), only add "Snaphot of" to name if original
has a non-null name.
- In verbose printing mode, remove printing of 'extras' and
only print '(owning contents)' of collection has a non-null name
o RooAddPdf
- Fix logic of recursive fractions constructor. Recursive additions
happen start on the rightmost pair of pdfs, recursively adding
one more pdf to the left at each iteration. Coefficients describe
the fractions of the leftmost pdf in each recursive addition,
starting with the outermost addition of the 1st pdf to the
som of all other pdfs, continuing with the fraction of the
2nd pdf being added to the sum of pdf 3-n etc...
o RooAbsCachedPdf
- Degrade 'parameters have changed' message from INFO to DEBUG
- Interface cache histogram objects to RooExpensiveObjectCache
with associated parameters given by RooChangeTracker
- Fix bug in printing: only print normalization object of
cache if it actually exists

original contents, to support sane implemlementation of
copying of optimized test statistics with multi-process
calculations.
- Fix redirectServers method for objects implementing multi-process
test statistics
o RooRecursiveFraction
- Invert incoming list of plain fractions when filling internal
list in ctor so that last fraction is 'special' instead of first
to support improved handling of recursive fractions in RooAddPdf
o RooAbsData
- Fix client-server reconnect handling for dataset observables
with parameterized ranges in terms of other dataset observables
- Add simplified createHistogram() method that takes
string with comma separated observable names and
three optional bin numbers. If bin counts are negative,
the ranges of output histogram are automatically calculated.
If the bin counts are positive, the ranges of the observables
are used for the histogram, unless the observable has an
open-ended ranges, in which case the automatic calculation
is used.
- Add createHistogram() method that takes a list of
RooCmdArgs that can serve as backend for all user
interface methods.
- Extend createHistogram() method with named arguments

- Add pointer to expensive object cache to use for any expensive
objects to be cached in association with this object
- Add recurseNonDerived option to branchNodeServerList
- Overload printAddress() to so that RooAbsArg base address
is printed rather than RooPrintable base address, which
can be different due to multiple inheritance

observables with parameterized ranges to cache.
- Add interface methods to get and set the associated
expensive object cache
- Add flipAClean() accessor method for corresponding
static data member to solve windows linkage problems.
o RooRealIntegral
- Add support for cache values of >1D integrals in
expensive object cache
o RooExpensiveObjectCache
- New repository class that holds expensive components of RooAbsArg
function objects along with the parameters value for which the
stored expensive object is valid. All newly created objects
are associated with a default singleton instance in memory,
but objects in RooWorkspaces are associated with a cache in the
workspace.
o RooMCStudy

previous 23538
o RooAbsSelfCachedPdf
- Follow changes in RooAbsCachedPdf
o RooCachedPdf
- Add option to override default choice of cache observables
(the normalization observables) with a specific set of variables
to make it possible to also cache p.d.f values for all values
of given parameters as well.
- Forward analytical integration capabilities to actual cache p.d.f
- Forward calls on preferred observable order to cached p.d.f
o RooDataHist
- Add option to bin dataset in alternate binning configuration, as
specified by binning name in constructor.
- Add feature to weight() function to enforce special boundaries
when interpolating a histogram representing a cumulative distribution function.
If so, lower-side bounds are forced to zero and upper-side bounds are
forced to 1.0 instead of the default mirroring strategy
o RooMsgService
- Add new topic NumericIntegration
- Show PROGRESS level messages by default
o RooAbsSelfCachedReal
- New base class for self-caching RooAbsReal objects analoguous
to RooAbsSelfCachedPdf
o RooCachedReal
- New class to cache arbitrary RooAbsReal function objects,
analogous to RooAbsCachedPdf
o RooRealBinding
- Add feature to save and restore values of input variables,
used by RooRealIntegral to restore observable values after numeric
integration to original values.
o RooLinearMorph
- New operator p.d.f class implementing using the algorithm described
by Alex Read in NUM A 425 (1999) 357-369 'Linear interpolation of histograms'.
This class implements a generalization for continuous p.d.f
o RooAbsRealLValue
- Following changes in RooAbsLValue
o RooHistFunc
- Real-valued function modeled by external RooDataHist object, analoguous to RooHistPdf,
but without normalization support and allowing negative histogram values
o RooAbsCachedReal
- New abstract base class for caching functions, analoguous to RooAbsCachedPdf.
o RooFracRemainder
- New dedicated helper class to calculate the remainder fraction of a RooAddPdf, i.e. 1-sum(i)x_i
for a given RooArgSet x
o RooCustomizer
- Fix memory management issue for sterile use
o RooAbsCategoryLValue
- Follow changes in RooAbsLValue
o RooNumCdf
- Specialization of RooNumRunningInt to calculate running integrals of p.d.f.s:
the running integral is by construction normalized to one exactly, taking out
any possible imprecisions in the regular integral calculation and by imposing
special constraints on the RooHistFunc that models the output so that the boundaries
are constrained to exactly 0 and 1 when interpolation is used.
o RooFFTConv
- Fix bug in cache naming algorithm
- Follow changes in RooAbsCachedPdf
o RooChangeTracker
- New special purpose object that tracks changes in a given set of variables, used
to determine if cached p.d.fs in RooAbsCachedPdf and RooAbsCachedReal need to
be recalculated due to parameter changes. In addition to valueDirty tracking,
an explicit comparison can be made to stored reference values of variables,
to avoid recalculation of expensive quantities in case a valueDirty is propagated
even if the value did not change (this can e.g. happen when you step though
a RooDataHist where usually only one of the observables changes value, but
all observables propagate a valueDirty every time)
o RooHist
- Bug fix in makeResidual()
o RooAbsReal
- Fix small memory leak in createIntegral
- Expand functionality of fillDataHist: optional correction for binVolume
when filling, and optional progress indication.
- Modify logEvalError() so that when cumulative logging for Minuit is disabled
that messages are printed through the standard message logging service.
- Modify error logging so that name of objects are stored in addition to
pointers so that delayed logging of errors of (cache) objects that no
longer exists can be performed correctly.
- Add virtual function preferredObservableScanOrder() to indicate preferred
order in which multi-dimensional functions should be scanned into a
RooHistPdf, which may matter greatly for the performance of certain
p.d.f.s like RooFFTConvPdf and RooLinearMorph
- Add new function createRunningIntegral() which constructs for a given F(x,y)
a Int[xlo,x] F(x',y) dx. The default strategy is to construct the underlying
integral with createIntegral() and adapt it with a RooCustomizer and a RooParamBinning
to a running integral. In case it concerns a one-dimensional numeric running
integral, the running integral is represented by a dedicated class RooNumRunningInt
which scans the integrand and numerically integrates the scanned histogram
o RooAbsCollection
- Bug fix in nameFieldLength handling of print routine
o RooAbsCachedPdf
- Introduce explicitly the strategy that the cache contains the _normalized_ p.d.f. values,
so that no postior normalization integral is required. This has the added advantages that
the cache p.d.f can be instructed to consider itself normalized skipping an explicit
normalization step in the RooHistPdf.
- Add utility function getCachePdf() and getCacheHist() to retrieve cache p.d.f and histogram
for a given choice of normalization set
- Clean up structure of CacheElem nested class by making guts private and providing accessor
function for derived CacheElem classes. Virtualize cache creation with a new member function
createCache that will allow derived classes to create a derived CacheElem.
- Forward integration handling to cache pdf actually being used
o RooDataHistSliceIter
- Follow changes in RooDataHist for alternate binning
o RooRealMPFE
- Follow changes in eval error logging in RooAbsReal
o RooAbsPdf
- Add createCdf() function to create cumulative distribution functions from p.d.f.s. This is
quite similar to RooAbsReal::createRunningIntegral() but with some c.d.f specific features
related to constraints on normalization
o RooAbsArg
- Fix bug in optimizeCacheMode()
o RooBrentRootFinder
- Improve error messaging through RooMsgService interface.
o RooCmdArg
- Expand payload from 2 to 3 strings
o RooSimWSTool
- Complete rewrite of RooSimPdfBuilder integrated with RooWorkspace for object storage.
o RooNumRunningInt
- New dedicated class to calculate running integral of any function that does not have
an analytical integral implementation. This class scans such a function in a histogram
and then numerically integrates the histogram. The filling of the histogram is performed
adaptively using a recursion division strategy with a precision cutoff to save time
of the filling of smooth functions in finely binned histograms
o RooMultiCategory, RooSuperCategory
- Minor tweak in name of proxies
o RooAbsIntegrator
- Deploy save and restore functionality of RooAbsFunc/RooRealBinding to restore observable
values to prior values after an intergration step.
o RooMinuit
- Fix gcc 4.3 compiler warning
o RooWorkspace
- Add bulk import() function taking a const RooArgSet instead of a RooAbsArg
- Add RecycleConflictNodes() option to ignore conflicts and simply recycle internal
nodes when a different external node is encountered.
- Add new accessors catfunc() for category functions, arg() for generic RooAbsArgs,
and funcArg() for fundamental arguments of any type.
- Add separate section for category functions in Print()
o RooHistPdf
- Add option to declare contents unit normalized. When activated, the analytical
integral is hardwired to 1.
- Add option to propagate cdfBoundaries mode to the underlying RooDataHist.
o RooAbsOptTestStatistic
- Optimize handling of empty rangeName specification (from Alfio)
o RooSimultaneous
- Tune proxy names
- Make p.d.f return zero, in case index category is in state where no p.d.f is assigned,
rather that assert(0)
o LinkDef3.h, Module.mk
- Add new class definitions

- 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.

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

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

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

- Adapt code to make it work with both RooAbsAnaConv objects and
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

Integrals and normalizations of constructed on the fly from the original and
multiple sequential projections steps are automatically consolidated into a single
step (i.e. creating a projection of a RooProjectedPdf will result in the same
integrator configuration as creating the same projection immediately from
the original p.d.f.). Intelligent handling/forwarding of internal generator
techniques is not implemented yet.

i.e. p.d.f.s. functions variables and datasets. Objects imported in the
workspace are automatically cloned and internally connected to provide a
consistent working environment. Workspace also serve to persist complete
analysis projects

o RooAbsAnaConvPdf
- Throw away cache of convCoef objects in serverRedirect (solves generator
problem reported by Gerhard)
- Follow interface change of getNormObj()
o RooAbsArg
- Add option pattern string argument to printCompactTree() that causes only
the components with names that match the pattern to be printed
- Add getCloningAncestors() utility function that returns list of pointers
to ancestors in the objects cloning history
o RooAbsGenContext
- Add auxiliary prototype variables to the _theEvent (solves generator problem
reported by Gerhard)
o RooAbsPdf
- Change getNormObj() to take both nset and iset argument so that it can
also cache fractional integrals. This is needed to support the use of
RooAddPdf objects in RooExtendPdf as fractional range intergrals of
RooAddPdfs cannot be represented as a ratio of two integrals in
a the restricted and full range divided by each other
o RooAbsReal
- Change const declaration in one of the createIntegral() declarations
o RooAddGenContext
- Follow interface change in RooAddPdf::updateCoefCache()
o RooAddPdf
- Pass both supplemental and regular normalization set to updateCoefCache() to
be able to deal with situations arising from using RooExtendPdf where the
former is a null pointer.
o RooConvGenContext
- Add auxiliary prototype variables in constructor to list of variables of model
and pdf.
- In initGenerator() resync observable lists _pdfVars and _modelVars to those
in the event that is passed to initGenerator(). Fixes generator problem reported
by Gerhard.
o RooExtendPdf
- Change way fractional integral factor is calculated in expectedEvents(): use
1-step createIntegral() procedure available through new getNormObj() interface.
This fixes a problem calculating the number of expected events in a range
of a RooAddPdf.
o RooGenContext
- Use createIntegral() interface to construct AcceptReject input function rather
than direct call of RooRealIntegral constructor.
o RooProdGenContext
- Small fix in handling of imported dependents in product parsing phase of generator context
o RooProdPdf
- Add forgotten handling of extended PDF term in selected constructors
o RooProduct
- Extend functionality so that product input terms can include RooAbsCategories as well
o RooRealVar
- Introduce concept of 'shared properties' among clones of RooRealVars. This simplifies
user handling of certain RooRealVar properties that are synchronous among all clones
of a RooRealVar. A simple demonstration:
RooRealVar x("x","x",-10,10) ;
RooRealVar* x2 = x->Clone() ;
x.setRange("signal",-1,1) ;
x2->getMin("signal") // returns -1 ;
x2->setMax("signal",5) ;
x.getmax("signal") // returns 5 ;
The sharing is explicitly through cloning and not by name, so two independently
created objects with identical names will not share properties. The sharing
of properties is retained throughout persistence and unpersistence of objects.
For now the definition of the named ranges has been moved into the
shared properties part of RooRealVar and simplifies certain common uses cases such as
RooRealVar x("x","x",-10,10) ;
RooRealVar y("y","y",-10,10) ;
// lots of code
RooAbsPdf* F ; // constructed somewhere
// more code
RooDataSet* D ; // constructed somewhere
y.setRange("signal",-1,1) ;
RooPlot* xframe = x.frame() ;
D->plotOn(xframe,CutRange("signal")) ; // RRV 'y' inside 'D' knows about "signal" through sharing
F->plotOn(xframe,ProjectionRange("signal")) ;
- Increment of RooRealVar schema version number from 2 to 4
- Explicit streamer of RooRealVar has been extended to be able to stream RooRealVar v3 objects
properly and automatically eliminate/reconnect multiple instances of identical shared property
objects that may have been created in ROOT persistence. The streamer is also capable of
reading in v1 and v2 RooRealVars for backward compatibility
o RooSimultaneous
- Modify behaviour of expectedEvents(): if index category is included in normalization set,
return sum of expectedEvents() of all components, otherwise return value of expectedEvents()
of currently selected p.d.f. (the 'old' behavior)
o RooSharedProperties
- Base class for implementation of shared property objects such as RooRealVarSharedProperty
used in RooRealVar. This class embeds a UUID that allows reconnection of multiple RooAbsArgs
to a single instance of a shared property in the unpersistance phase.
o RooSharedProperiesList
- Container class for RooSharedProperties objects that serves as repository for shared properties.
Concrete implementations of RooAbsArg that implement the shared properties concept, such as
RooRealVar, have a an instance of RooSharedPropertiesList as a static data member. This container
class owns all shared properties objects and performs their memory management through reference
counting and automatically eliminates duplicate copies of unique shared properties that many
occur on unpersisting objects

This round of updates achieves two major goals
- Large (O(10-100)) speedup in handling of very
complex PDFS (>10000 nodes) by pervasive use
of self-expanding hash tables
- Fix outstanding problems with RooProdPdf
through new strategy to deal with cached
objects in cloning/server redirect operations
There is also a handful of minor fixes
------------------------------------------------
o RooSetPair
- New auxiliary class to store pair of RooArgSet pointers
o Roo1DTable
- Don't fill entries with zero weight
o RooAbsArg
- Add optional 2nd arg to printCompactTree() to store
output to file
o RooAbsCollection
- Initialize RooLinkedLists with hashing size threshold of 43
o RooAbsGoodnessOfFit, RooAbsOptGoodnessOfFit, RooProdPdf
- Follow changes in printCompactTree() syntax
o RooAbsOptGoodnessOfFit
- Remove all methods that implement dirty state optimization
and constant term caching (migration to RooAbsReal)
o RooAbsReal
- Various fixes in plotAsymOn fix plotting of asymmetries
in conjunction with ProjWData() and Slice()
- Add methods that implement dirty state optimization
and constant term caching (migration from RooAbsOptGoodnessOfFit)
o RooDataProjBinding
- Remove some old debug code
o RooHashTable
- New constructor option allow to choose hashing by name,
pointer or objects Hash() value
- Switch to using TMath::Hash() fast hashing method
using 'especially selected random numbers' (!)
- Add kludgy support for storage of RooLinkedListElem
and RooSetPair objects, which do not inherit from TObject.
(A full redesign of RooLinkedList and RooHashTable is needed
at some point)
o RooHist
- Fix print statement
o RooHistError
- Lower (n,m) threshold for calculation of approximate binomial
error to avoid factorial overflow problems.
o RooLinkedList
- Introduce automatically activated hashing by name and pointer
to speed up handling of long lists beyond size threshold
given in ctor (zero threshold disables this features)
- Automatically rehash tables when #entries becomes greater
than hash table size
o RooNameSet
- Sort contents upon insertion. This fixes broken operator==
for certain set comparisons
o RooNormListManager
- Add support for 'sterile' operation. If contents is sterilized
via new sterilize() member function or use of sterile copy
ctor RooNormSetCache information is retained (and thus
ordering and slot indeces used by client classes) but
stored contents associated with given iset/nset pairs
is deleted. A 'setNormList()' call that maps to a
sterilized slot will recycle that slot. Optional new argument
in getNormList will tell client that requested information
has been sterilized rather than not being there.
o RooNormSetCache
- Store set pair information in hash table of RooSetPair objects
rather than two fixed size arrays of RooArgSet pointers.
This greatly improves lookup speed (indexed by set pointers)
and automatically expands the capacity of the set cache
as is needed for very complex fits.
o RooProdPdf
- Abandon strategy to forward redirectServer requests to
cached product configurations. This strategy has turned
out to be flawed as insufficient information is available
in the redirectServers context to do the right thing
under all circumstances. Invocation of redirectServerHook()
will now sterilize the cache, using new RooNormListManager
feature
- Modify getAnalyticalIntegralWN(), which looks up cached
product configurations by index to recognize sterilized
entries. If such an entry is encountered, it is reconstituted
on the fly.
o RooRealIntegral
- Store owned clones of factorizing observables instead of linking
to instances provided in ctor as ownership related of those
turns out not to be well defined.
o RooRefCountedList
- Set hashing threshold of underlying RooLinkedList at 17
o RooSimPdfBuilder
- Increase buffer sizes of RooStringVars in set returned by
createProtoBuildConfig() to accomodate requests for ever
more complex pdf configurations.

Preparation for V1.04 -- RooProdPdf maintance and upgrade
---------------------------------------------------------
o LICENSE, RooBanner
- Update to year 2004
o RooAbsArg
- Add DeleteWatch debug feature: verbal notification
if an object with this flag is beign deleted
o RooAbsGenContext, RooGenContext, RooAddGenContext,
RooConvGenContext, RooSimGenContext, RooMCStudy
- Introduce concept of auxiliary proto variables, which are
generated by other PDF components rather than an external dataset
o RooAbsPdf,RooConvolutedPdf,RooSimultaneous,RooAddPdf
- Modify genContext() to allow optional specification of auxiliary
proto variables
o RooCmdArg
- Add RooProdPdf as friend
o RooGenProdProj
- Modify so that it will work without a denominator term as well
- Fix in memory management that created hidden links between deep
cloned trees that involved RooProdPdf nodes with cached information
o RooProdGenContext
- Enhance functionality so that it can correctly and optimally
generate events for 'correlated product' PDFS. Now, irriducible
PDF terms are generated in a dependency order: 'imported
dependents', i.e. dependents over which a PDF doesn't normalize
are always guaranteed to have been generated by another term
before the importing term is generated. Left over terms wich are
cross importing cannot be disentangled with a linear dependency
scheme and are generated as a monolithic PDF. The ProdGen
context uses the new auxiliary proto variables to correctly
generate the correlation between imported and normalizing
observables.
o RooProdPdf
- Fix some outstanding link management problems
- Add new ctor with named arguments that allows to specify
correlated products
- Adjust product factorization to understand concept of 'imported'
dependents, which allows to split composite terms that would
otherwise be irriducible
- Add term grouping algorithm that groups together irriducible terms that
share dependents in mixed roles (normalizing vs imported) over which is
integrated. Such integrals can only be calculated properly if the
entire product of such terms is integrated rather than the terms
individually.
- Reorganize code a bit: break factorization, term grouping and
prefabrication of partial integral lists into several functions.

Generalization of RooProdPdf
----------------------------
Requirement that observables of component PDFs do not overlap is eliminated.
Non-factorizing terms in normalization and projection are calculated
explicitly. The event generator is modified similarly
o RooAbsArg
- Add RooGenProdProj as friend
o RooAbsPdf
- In isDirectGenSafe() add check that observable is direct
server of pdf.
o RooGenContext
- Delegate check that internally generable observable is direct
dependent of pdf to RooAbsPdf::isDirectGenSafe()
o RooNormListManager
- Bug fix in copy ctor: When owning list is copied, also copy
contents
o RooProdGenContxt
- Modify generator context so that it can handle non-factorizing
PDF terms. These terms are now represented as sub products
that are delegated to a RooProdPdf instance that used the
generic generator context
o RooProdPdf
- Modify class so that it can handle non-factorizing PDF groups.
In calculation, irreducible non-factorizing terms are isolated
and calculated by in instance of the RooGenProdProj auxiliary class.
- Add internal generator interface for the benefit of RooProdGenContext.
Advertise direct generator capability of component PDFs for observables
that appear in only one of component PDFs.
o RooGenProdProj
- New auxiliary class for RooProdPdf to calculate normalization and
normalized projections for non-factorizing product terms.
For these groups the numerator and the denominator of the
projection are integrated before division, instead of the
other way around. Analytical integrals are used whereever possible.
o RooProduct
- New class representing the product of RooAbsReal objects,
analogyous to RooProdPdf. This version doesn't do any handling
of (partial) analytical integrals

- Add missing return in evaluate()
o RooAbsPdf
- Implement redirectServersHook() to forward server redirection
to all cached normalization integrals
- Disable listing of indirectly selected components in plotCompOn()
(not that useful, and potentially very verbose)
o RooAddPdf
- Revert to version with single coefficient projection integral
(instead of ratio of integrals). Add supplemental normalization
term to coefficient projection integrals to handle projection
of RooAddPdfs where the set of dependents of the components
do not overlap (i.e. F(x,y) + G(y,z))
- Add operModeHook() and redirectServersHook() to forward
either operation to the cahced coefficient projection integrals
o RooNormManager
- Add getNormByIndex() and cacheSize() to facilitate server
redirection.
o RooProdGenContext,RooProdPdf
- Back out experimental version that allowed overlapping discrete dependents
due to unsolved problems
- Implement redirectServersHook() to forward operation to cached
projection lists
o RooRealIntegral

lists to correctly handle server changes on the fly
- Change getDependents() to only return value-server dependents
(so that Int(gauss(x,m,s))dx doesn't list x as a dependent)
o RooAbsOptGoodnessOfFit
- Instead of switching all nodes to ADirty opermode, only
switch those that depend on the observables. (This will
leave integrals over all observables in Auto mode)
o RooRefCountList

CPUs and calculation of GOFs from simulatenous PDFs.
o New class RooAbsOptGoodnessOfFit
- Abstract base class for goodness-of-fit variables
that calculate the PDF value at each data point in the
given dataset. It implements various optimizations:
caching of constant terms, elimination of unused variables etc.

to cache multiple normalization integrals for a PDF.
This greatly increases the efficiency for certain situations
where PDFs are alternatingly called with 2 or more different
normalization choices
- Reimplement fitTo() in terms of RooNLLVar and RooMinuit.
- Reimplement plotNLLOn() in terms of RooNLLVar and plotOn()

parallelized goodness-of-fit calculations. On linux
hosts, these processes don't exit when the parent process
exits. This class sends termination signals when this
singleton class is deleted
o RooMath
- Activate CERF disk caching by default
o New class RooMinuit
- New seamless interface between RooFit objects and MINUIT
Class propagates information forth and back between RooAbsArg
objects and minuits internal memory buffer (e.g. parameter
values, errors, step sizes, constant status)
- This class minimizes any RooAbsReal function (doesn't need to
be a NLL or Chi2)
o Removed class RooNLLBinding
- Obsolete after introduction of RooNLLVar
o New class RooNLLVar
- Implementation for NLL of RooAbsOptGoodnessOfFit
o RooNameSet
- Fix memory leak
o New class RooNormManager
- New manager class for normalization/projection integrals for PDFs
This class matches RooArgSet pointer pairs to the integration
and normalization sets to previously registered integrals.
Multiple pointer pairs can point to the same integral (e.g.
pointer to different RooArgSets with the same contents) and
multiple integrals can be cached. This class doesn't create
the normalization integrals. It merely indicates if it has
one or not, and leaves it up to the owning class to create
and register new normalizations
o New class RooNormListManager
- Similar to RooNormManager, except that RooArgLists of normalization
integrals are caches instead of single integrals
o RooNormSetCache
- Rework functionality. This class, used by RooNorm(List)Manager
manages multiple redundant RooArgSet pointer pairs that represent
the same projection/normalization configuration
o RooProdPdf
- Almost complete rewrite in terms of RooNormListManager
o RooRealConstant
- Minor const changes
o RooRealIntegral
- Streamline iterator use: Create various interator in ctor
and reuse them in evaluate() instead of creating and deleting
them on the fly
o New class RooRealMPFE
- Front end for MultiProcessor calculations. Class RooRealMPFE
takes a RooAbsReal as argument and calculates it in separate
process. Calculations can be started asynchronously with
the calculate() call. The rest of the interface (and behaviour)
is identical to that of the original RooAbsReal.
o RooResolutionModel
- Deprecate getNormSpecial - superceded by RooNormManager
o RooSetProxy
- Implement addClone(const RooAbsCollection&,...)
o Removed class RooSimFitContext
- Obsolete - replaced by RooMinuit/RooNLLVar
o RooSimGenContext
- Fix memory leak
o RooSimultaneous
- remove obsolete fitContext() method
o RooTreeData
- Reimplement caching. Cached functions are now stored in
a separate tree in the dataset. Main benefit of the new
implementation is that caches can efficiently be reset
and refilled on the fly
o makedocs
- Add stanzas for new tutorial macros

o RooAbsArg
- Keep track of cloning with attributes. add isCloneOf()
method to test if objects are clones
o RooAbsCollection
- Implement check of 'unique-name rule' in snapshot() method.
Disabled for the moment as we violate this rule in benign ways
in several places in the core code. This needs to be fixed first
o RooAbsPdf
- Add methods to specify numerical integrator configuration to be
used in normalization
There is one global default configuration (RooIntegratorConfig object)
and each PDF can optionally have a private configuration that
overrules the default one.
o RooAddPdf
- Add on-the-fly transformations for coefficients between
normalization sets. Users can now specify a
'reference normalization' via fixCoefNormalization() in
which the fractions will always be interpreted.
If no such reference set is specified the default behaviour
will prevail: the interpretation depends on the current normalization.
o RooAbsReal
- Change plotOn() such that when a PDF containing RooAddPdfs
is projected with data, an appropriate reference normalization
is set for each, if no user-supplied reference normalization
was set. This ensures intuitive behaviour of plotOn() for RooAddPdfs
- Add easy-to-use wrapper function for createProjection()
o RooErrorVar
- Add readFromStream/writToStream()
- Declare fundamental
o RooImproperIntegrator1D,RooIntegrator1D
- Add constructors from RooIntegratorConfig
o RooMCIntegrator
- Add constructor from RooIntegratorConfig
- Make #iterations and #call per iteration for grid refinement
and integration configurable parameters
o RooProdPdf
- Complete rewrite. Now _all_ permutations of integration/normalization
are correctly performed. New implementation uses a product
of partial integrals created with pdf->createIntegral()
o RooRealIntegral
- Add optional RooIntegratorConfig to ctor and pass to numerical
integrator ctors in various places
o RooSetProxy
- Fix server management for owning set proxies
o Many classes
- Anticipate potential failure of snapshot() due to unique-name
rule enforcement and handle such situations appropriately

A large number of small fixes and improvements
o Roo1DTable
- Modify Print() behaviour. Standard print will
only show non-empty fields, verbose shows all fields
o RooAbsArg
- Change getParameters so that it can accept 0 as
dataset pointer (implies no dependents)
o RooAbsPdf
- Follow plotOn() changes in RooAbsReal
o RooAbsReal
- Add optional const RooArgSet* projData argument to
plotOn(). Projected dependents that appears in this
dataset, if specified, will be projection via summation
over data instead of integration.
- Add clipInvalid option to bindVars() and propagate to
RooRealBinding
- Modify cleanBranchName() to truncate 'clean names'
(which are used for the TTree branch) to 63 chars
as cannot handle such cases (SEGV). In case name
is longer than 63 chars, truncate name at 46 chars
and suffix with _crc followed by hex representation
of CRC32 checksum of the full name.
- Add crc32() method to calculate the checksum of a string
o RooAddModel,RooAddPdf
- Do not evaluate PDF components multiplied by a zero coefficient
o RooAddPdf
- Fix DIV0 in analyticalIntegral if number of expected events
for all PDFs combined totals zero
o RooArgSet
- Add ability to readFromStream and readFromFile to optionally
flag read arguments with a user specified attribute
(Mostly useful to determine which elements have _not_ been read)
o RooConvolutedPdf
- Change declareBasis() signature from a RooArgSet& to a RooArgList&
to correctly handle cases where the names of parameters are identical
(e.g. tau=zero and dm=zero for prompt background models)
- Expand logic in RooGenContext. Add additional requirement for
use of optimized generator context: both the physics pdf and
the resolution model must support direct generation of the
convolution variable.
(Still have to fix RooAddModel/Pdf for cases where all components
can do direct generation)
o RooCurve
- Deploy RooRealBinding::clipInvalid feature to zero plotted functions
outside the validity range of their dependents
- Add extra points at (xlo,0) and (xhi,0) to obtain correct filling
pattern when using the 'F' draw option.
o RooCustomizer
- Add warnings for multiple split or replace rules on the same leaf
o RooDataSet
- Make read() take a const RooArgList& instead of a RooArgList&
and immediately make temporary copy for internal use.
- All constructors with string based cut: add default empty cut.
o RooFitContext
- Ctor: Compare limits on dependents in PDF and dataset if limits
of PDF are smaller and fully contained in those of the dataset,
adjust the dataset ranges in the internal copy and reject events
outside the PDF limits. If PDF ranges are not identical or fully
contained in dataset limits, give error message and abort.
- In fit() fix handling of parameters handed to TMinuit: set pmin/pmax
to the parameter value for constant parameters. For floating parameters
with open limits and without error, use 1/10 of the plot range
instead of 1/10 of the fit range.
o RooFormula,RooFormulaVar
- Change RooArgSet to RooArgList to pass formula parameters.
This allows construction of formulas with ordinal references
for list of parameters with multiple occurrences of the same
variable.
o RooRealBinding
- Add clipInvalid option, specified in ctor. If set, loadValues()
will first check if the values to be loaded are in the limits
of the bound objects dependents. If not the values are not loaded
and an invalid flag is set. If the invalid flag is set operator()
will return 0.
o RooRealVar
- Add various 'named parameter' functions on a trial basis
o RooSimFitContext
- Gracefully handle RooSimultaneous PDFs with missing PDFs.
o RooSimGenContext
- Forgot to set index state in theEvent RooArgSet when generating
the index category
- Remove forced normalization of index state in evaluate()
- Remove dummy plotOn() method and specialized plotOn() with data
method as projection over the index state can now be handled
the regular plotOn method. Overload RooAbsPdf::plotOn to
force caller to specify projection dataset for the index category
if projection over the index category is requested
o RooTable
- Remove print(), add default Print(Option_t *), and reimplement
printing via inheritance from RooPrintable
o RooTreeData
- In loadValues(RooTreeData*) explicitly check isValid() of
each element of _vars after copying. If any is invalid,
reject the event.
- In table() change simple clone of tableVar to deep clone.
Implement use of optional cut string (accidentally omitted sofar)
o RooTruthModel
- Add highly trivial direct generator for the convolution variable
o RooDataProjBinding
- New lightweight binding between an RooAbsReal and a dataset
that returns the projection of the real over the dataset
via summation. If the dataset only contains category variables
an supercategory of all the datasets categories is created
and the data is summed (with appropriate weights) over the
supercategory states instead of over every event.

o RooAbsPdf
- Remove obsolete dummy functions Scan(),Parameters(),ContourPlot()
- Fix printing of PDFs in 'Standard' mode
- Add plotNLLOn(RooPlot*,...) method implementing RFTs Scan() functionality
- Add paramOn(RooPlot*,...) method implementing RFTs Parameters() functionality
- Add contourPlot() plotNLLContours method, implementing RFTs PlotContour()
functionality. Implementation is deferred to RooFitContext.
o RooAbsReal
- Add checks in frame() method that plot range is neither infinite nor zero
o RooAddModel
- Replace all existing constructors (except copy ctor) with a single
list based constructor (as done in RooAddPdf).
- addModel(), addLastModel() methods removed.
- Implement analytical integration technique performed in RooAddPdf
when model is used as an unconvoluted PDF. Implementation introduces
getAnalyticalIntegralWN(),analyticalIntegralWN(),forceAnalyticalInt(),

o RooAddPdf
- Add new constructor with PDF list only. Builds an extended sum PDF
from a list of extendable components. Coefficients of the PDFs
are calculated from each PDFs contribution to the total number
of expected events.
o RooFitContext

in TMinuit::Contour, a fast minimization (Migrad only, strategy 0) is
performed on the PDF before the contour plots are made.
o RooNLLBinding
- Lightweight binding objects combines a PDF and a data set and returns
the resulting negative log likelihood as function of one or more
of the PDFs parameters
o RooNorm
- Port of RFT RooNorm class
o RooCutNorm
- Port of and extension of RFT RooCutNorm class. RFC implementation
supports cuts in an arbitrary number of dimensions.
o RooProdPdf
- Introduce support for extended likelihood fits. If exactly one
of the component PDFs can be extended, that the product can be
too (returning the extendable components expected number of events)
o RooSimultaneous
- Introduce support for extended likelihood fits. If all of the
component PDFs can be extended, than the simultaneous PDF can be too
(returning the number of expected events of the active PDF)

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

Major cleanup in integration of normalization functions
Miscellaneous small improvements and fixes
o Roo1DTable
- Add get(),getFrac() methods to retrieve contents
o RooAbsCollection
- Add selectCommon() method to create new collection
containing args common to two sets
o RooAbsData
- Minor const-correctness changes
o RooAbsReal
- Rearrangement of getAnalyticalIntegral/analyticalIntegral entry points.
Both functions now exist with and without a 'const RooArgSet* normSet'
The functions with normSet are used by RooRealIntegral, and its default
implementation handle the pass-through scenario (code 0 = getVal(normSet))
and defers other codes to the non-normSet variant.
Simple PDFs should implement the non-normSet variants, as they used
to do sofar, except they no longer should (or are able to) process
the passthrough scenario.
Advanced PDFs such as RooAdd,ProdPdf, RooConvolutedPdf that implement
complex integration schemes that depend on the exact normSet configuration
reimplement the getAI,aI functions with normSet.
o RooResolutionModel, RooAddModel
- Implement (or forward in case of RooAddModel) new getNormSpecial method.
This function is identical in functionality to RooAbsPdf::getNorm()
except that it caches a separate copy of the normalization integral.
This member is introduced for the benefit of RooConvolutedPdf::analyticalIntegral
which, in case of a normalized integration, alternatingly calls two different
normalizations. In the original single cache code, this would lead to
100% caching failure and 300% slowdown of the code. getNormSpecial is
protected for access by RooConvolutedPdf only.
o RooAddPdf,RooProdPdf,RooSimultaneous,RooConvolutedPdf
- Re-implement distributed analytic integration bookkeeping using
the auxiliary RooAICRegistry class, which keeps track of multiple
analytical integration codes (hence AIC)
o RooAICRegistry
- New auxiliary class to faciliate the management of distributed analytic
integration.
o RooArgSet
- Minor printing fix
o RooConvolutedPdf
- Complete rewrite of handling of analytical integrations. For RCP objects
analytical integrations are not all necesarily analytic, but include
integrations deferred to convolution objcts. Analytical integrations
are split off for coefficient terms. Complete double bookkeeping introduced
for 'integration' part of analytic integration and 'normalization' part
of integration, each of which can have a different argSet to defer
to the convolution objects and a different coefficient analytical integration
code. Current implementation is believed to be complete.
o RooFormulaVar
- Follow signature change of getAnalyticalIntegral/analyticalIntegral
o RooMath
- Implement file cacheing scheme for complex error function lookup table.
To invoke persistent caching, call RooMath::cacheCERF(kTRUE) prior to
use
o RooRealAnalytic
- Store and forward normalization set to analyticalIntegral call of
bound RooAbsReal
o RooSimultanous
- Implement new plotOn() method, taking a dataSet which can correctly
project a RooSimultaneous. The code is mostly copied from RooAbsReal::
plotOn, except that the plotted pdf is constructed as a RooAddPdf
of the RooSimultaneous components, weighted by the fractions found
in the passed dataset
o RooTreeData
- Small const-correctness fixes

and corresponding proxy. Introduce RooArgList where appropriate
as replacement of a TList of proxies, eliminate all use of TList
inherited functions in RooArgSet/List.
Some optimizations implemented following profiling studies
Various fixes for compilation with Solaris CC 5.0
o RooAbsArg
- Change signature of server management function to use RooAbsCollection
instead of RooArgSet
- Add proxy management support for new RooListProxy class
o RooAbsPdf

o RooAddPdf, RooConvolutedPdf, RooFitContext, RooSimFitContext,
RooFitResult, RooPdfCustomizer, RooProdPdf,
- Change implementation from using TList to using RooArgList
o RooAbsCollection
- New abstract base class for collections of RooAbsArgs. This
class contains mostly code from the former RooArgSet implementation
o RooArgSet
- Re-implement as derived class of RooAbsCollection. A RooArgSet
cannot contain duplicates (as before), but also doesn't give
random access (by index) to its member elements
o RooArgList
- New implementation of RooAbsCollection that allows duplicates
in the list, allows sorting and lookup by index.
o RooListProxy
- Proxy version of RooArgList, similar to RooSetProxy. To be used
as data member of RooAbsArg implementation to hold external
RooAbsArg references.

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.

o RooAbsArg
- Increase (temporary) verbosity of proxy manipulations
o RooAbsPdf
- add matchArgs(....,RooArgSet) to allow matching of non-proxied
RooAbsArgs
o RooConvolutedPdf
- Skip evaluation of convolution terms if coefficient is zero
o RooFormulaVar, RooFormula
- add getParameter(index), getParameter(name) functions
to access pointers of ordinal or named references in formula
(needed by resolution models for basis functions)
o RooResolutionModel
- Store convolution dependent
- Require that primary variable of basis function for convolution
is the resolution models convolution dependent.
- Add servers of basis function as servers to resolution model
instead of basis function itself. The latter confuses the
integration logic, since we don't really use the basis function
object
- Add support for basis function enumeration via the pure
virtual basisCode() function.
- Make isBasisSupported() concrete, calling basisCode(),
- Modify clone() operator of resolution model to name as
argument as sterile cloning and subsequent name change
doesn't work: it breaks the client-server links after
a server redirect. This change should be propagated to
all classes.
- Make changeBasis() virtual because RooTruthModel needs a slightly
different behaviour
o RooTruthModel
- Unlike other resolution models, the basis function must be
a server of this model, as RooTruthModel actually evaluates
the object. Not doing so causes a disconnect between
the basis and the resolution model after a recursive server
redirect. An overloaded changeBasis() supports this non-standard
behaviour

o Overhaul new RooSetProxy
- RooSetProxy is a derived class of RooArgSet, so it can be
treated as an ArgSet by the user
Contents is automatically updated on redirectServers
and contents can be automatically declared as value/shape
server. The default server link behaviour is controlled
in the SetProxy constructor, and can be overridden, if necessary
with a special ::add() member function.
o RooRealIntegral, RooSuperCategory
- Adapt to use new RooSetProxy for their list management

Reorganize analytical/numerical integration structure
o RooAbsArg
- Back out 'integration dependents' option in getDependents()
(logic moved to RooRealIntegral)
- checkDependents is by default always OK
o RooAbsRealLValue
- Add isSafeForIntegation(const RooArgSet& depList) method
in which an LValue can indicate if it is OK to use the
object as LValue in integration fo the present
parameter/dependent configuration is
o RooRealIntegral
- Move all logic to decide what to integrate numerically/analytically
and where to use LValue and depth-expanded RValue into RRI ctor.
Summary of logic:
For every server of function that is to be integrated
if (RealLValue && isSafeForIntegration && noOverlapWithOtherServers)
Integrate of LValue
else if (CategoryLValue && noOverlapWithOtherServers)
Sum over LValue
else
Integrate/Sum over leafNode dependents of server
Now, all details of integration technique are completely contained
in RooRealIntegral, which can _always_ be performed (if N-dimensional
numerical integration is implemented)
Other changes
o RooFormulaVar
Allow new variable names in formula expression (@0, @1, ... @n)
that reference the nth object in the given RooArgSet.
(e.g. "@0 + @1 * @2")

o RooAbsArg
- In destructor, only print out warnings about live clients
that get cut off in verboseDirty() mode.
For automatically declared RooAbsArg this error condition
never occurs, but for client/server links in lists, the
order of deletion doesn't take these link directions into account.
o RooCategory
- Disallow defineType("") with a semicolon in the name.
This would confuse the reverse mapping of
RooSuperCategory::setIndex()/setLabel()
o RooArgSet
- Make default clone/copy ctor not copy the contents of the
list (Some core classes changed that used this feature)
- Extend snapshot function to ::snapshot(Bool_t deepCopy)
which allows to make both shallow (only list contents copied)
and deep snapshots (also all dependents of list contents
copied and added to list)
- Modify replace() to use AddBefore();Remove() instead
of Remove();Add() so that a replace call doesn't interfere
with an iterator over the RooArgSet
o RooRealIntegral
- Change dependent type checking from RooRealVar/RooCategory
to RooAbsRealLValue/RooAbsCategoryLValue
o RooSuperCategory
- Add MakeIterator() function which returns a RooMultiCatIter
on the super categories servers.
- Implement setIndex/setLabel(), which decodes the composite super
label into labels of the input categories
- Make use of new RooSetProxy which proxies the RooArgSet list
of input categories
- Enhance verbose printing
o RooGenCategory
- Port/rewrite from RooFitTools. User method scanned for all states
and translated into a
'SuperCategory type-index -> GenCategory type-index'
map (int-to-int via a simple array), making the class substantially
faster. The mapping is revised upon a shapeDirty() which is
propagated from all the input categories
o RooAbsCategory
- New abstract common base for RooArgProxy and RooSetProxy
o RooSetProxuy
- Proxies a RooArgSet. Essential service provided: upon a
redirectServers the list contents is replaced with the
new pointers from the redirection list.

*** Changes to allow a dataset to cache of derived objects ***
o RooAbsReal, RooAbsCategory and RooAbsString
Now each implements a protected method attachToTree, which allows to
connect the cache of any RooAbsArg to a TTree column
All other implementations (RooRealVar etc) removed
o Most classes
Type-blind assignment RooAbsArg* <...>::operator(const RooAbsArg*)
has been replaced by RooAbsArg::copyCache(RooAbsArg *), which is
needed for data set copy operations.
A new method RooAbsArg::syncCache(RooDataSet *)
can be used force to update the cache before a copyCache call.
o RooDataSet
- Holds a list of _cacheVars in addition to _vars, which are not
owned by the data set, but are updated nevertheless.
The cache list is not copied in a Clone() or copy operation.
- New methods cacheArg(RooAbsArg&) and cacheArgs(RooArgSet&)
register derived objects for caching in the dataset.
The values for these derived objects for each row of the tree
will be calculated and stored as a new column in the tree.
The cache of the derived object is attached to that tree column.
On a RooDataSet:get() row-load call, a setDirty(kTRUE) is called
for each cached (and uncached) object to propagate a value change
to the cached objects clients. Then immediately a setDirty(kFALSE)
is performed on the cached objects, to impose that the tree-loaded
value of the cache is correct and doesn't need to be recalculated.
o RooFitContext
- Optimizer not uses cacheArgs instead of addColumn, which
is integration-safe and can now be used on any derived object
with constant parameters
o RooAbsPdf
- Another iteration in the structure of getVal.
To make data set attachement work, the normalized value is
now stored in the cache instead of the raw value.
*** Cleanup of assignment operator ***
o RooAbsRealLValue/RooAbsCategoryLValue
- Implements assignment to Double_t/(Int_t,const char*)
o RooRealVar/RooCategory
- Implemements assignment to RooRealVar/RooCategory
o All other assignment operators deprecated
- No more assignment of derived types to each other
(conceptually unclear)

o Another major round of const-correctness improvements
o Add RooDerivedReal as an intermediates class between
RooAbsReal and RooRealFormula,RooRealIntegral,RooUnblind*
the getVal() -> cache check -> traceEval() -> evaluate()
chain has been moved into this class.
Derived Classes of RooDerivedReal only need to implement
evaluate() for contents definition. The getVal() of RooAbsReal
return the straight contents of _value.
o Added RooRealIntegral class, which represents the integal and/or sum
over various RooRealVar/RooCategory dependents of a generic RooDerivedReal
Integral value is cached and updated when the value of one of the
non-integrated dependents of the integrated functions changes
(detected via valueDirty bit propagation), or if the integration ranges
of one of the integrated dependents change (detected via shapeDirty
bit propagation).
If the RooDerivedReal supports analytical integration (implemented
via the getAnalyticalIntegral/analyticalIntegral functions) it's
analytical integrator is used. Otherwise a numerical integration algorithm
is used (currently limited to 1-dimensional integrations)
Summation of an arbitrary number of category dependents is supported
but not implemented yet, pending the port of RooSuperCategory, which
will support a trivial implementation.
Analytical integation interface: Each RooDerivedReal has 2 functions
implemented
- getAnalyticalIntegral(RooArgSet& integrandList),
which determines if analytical integration is supported
for the given list of integrands. If not, it returns
code 0. If yes, it returns a positive code, which RooRealIntegral
will pass to analyticalIntegral().
- analyticalIntegral(Int_t code) Performs or dispatches the
analytical integral represented by the code assigned by
getAnalyticalIntegral()
In theory, the above scheme could be implemented with just one
function, returning a pointer to a member function, but
pointer-to-members are not supported by ROOT due to portability
problems. The current scheme is inspired on the TFormula implementation
of referencing external parameters.
A default implementation in RooDerivedReal handles the default
(no analytical integration available) case.

o Add blinding support
- RooDataSet can now read mixed blind/unblind data, if the
blinding string (if present) is always the same.
The data set dynamically adds a 'blindState' category to
it's internal variable list which indicates if a given event
is blinded or not.
- Imported RooFitTools/RooBlind as RooBlindTools
- Created two unblinder engines RooUnblindCPDeltaTVar and
RooUnblindCPAsymVar. To perform blinding to do
RooRealVar deltat(...)
RooCategory tag(...)
RooCategory blindStat(...) // All these should come from a RooDataSet
RooUnblindCPDeltaTVar deltat_ub("deltat_ub","DeltaT unblind",
"Blinding String",deltat,tag,blindsStat)
OR
RooRealVar sin2b(...)
RooUnblindCPAsymVar sin2b_ub("sin2b_ub","Sin2Beta unblind",
"Blinding String",sin2b)
Then feed deltat_ub and sin2b_ub in the PDF.
the print() and read/write methods of the unblinders show some
configuration information, but don't reveal the unblinded value
The getVal() of the unblinders is 'protected' and can only be
accessed by RooDataSet
o Some cleanup in dirty flag propagation code
o Optional indexing category in RooDataSet::read that tells from which file
a given event is coming. A dummy category should be appended to the varlist
and it's name should be given as the last argyment in the RooDataSet ctor.
If the filespec is "fileA,fileB,fileC", for each file a new index type
is created with values 0,1,2 etc.. and labels ('file000','file001' etc).
One can also explicitly assign index labels to each file using the
following file spec string: "fileA:Dstar,fileB:Dstar,fileC:Jpsi".
In this example fileA and fileB will have index label Dstar (value 0)
and file C has label "Jpsi" (value 1)
Finally it is also possible to predefine label types in the index
category. RooDataSet::read will use the existing label/values defined
and assign new ones where undefined.
o Fix type in RooAbsArg::Print()

o Extend RooFormula to understand RooCategory labels '<catName>:<catLabel>'
so you can e.g. do (tagCat==tagCat::Kaon)
o Transplant and rework most advanced reading options from RFT/RooVarList
to RFC/RooArgSet
- Nested if statements
if (conditional)
else if (conditional)
else
endif
Conditionals are evaluated by a RooFormula object that can use the
entire arglist as variables
- Recursive include statements
include <filepath>
- Some useful other commands for configuration file use
echo "message" -> Print message while processing
abort -> Force termination of read with error status
Handling of errors in the input file format is fairly exhaustive.
o Some reworking of the RooStreamParser in the way newlines are handled.
Some of the clients of RSP have been changed accordingly.
Main new feature is a RSP::atEOL() member that determines if there is
a newline between the last read token and the next token to be read.
o Temporarily made RooAbsArg::Print/printToStream non-const as the
implementation in some subclasses call a non-const getVal()
This problem must be fixed for good in all classes soon.
