Diff to previous 24285


   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

   - Add parameters() method returning the tracked parameters


 o RooRealSumPdf

   - Implement component selection functionality in plotting as
     is available for RooAddPdf


 o RooEfficiency

   - Implement analytical integral over acceptance category
     (it is always 1.0)


 o RooHist

   - Implement ability to handle RooAbsData::None error bars
     (i.e no errors)

   - Expand functionality of constructor taking two TH1s
     to also represent the efficiency binomial in addition
     to the assymmetry binomial

   - Add addEfficiencyBin() method to handle calculation
     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.

   - In plotOn() support the new Slice() argument for categories
     that allow inline specification of of the slice position.

   - Also add support for the PrintEvalErrors(Int_t numErr) and
     EvalErrorValue(Double_t value) arguments to allow better control
     of evaluation error handlign during plotting.

   - Also add support for the MoveToBack() argument that immediately
     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


 o RooAbsTestStatistic

   - Reimplement copy constructor to initialize from scratch from
     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
     to take AutoBinning and AutoSymBinning arguments to
     automatically calculate the ranges of the output histogram
     with the specified number of bins.


   - Add a table() method that takes a set of RooCategories
     and returns a table of the output states of a RooSuperCategory

   - Add support for EvalErrorWall() named argument in fitTo
     to give user control of the 'NLL wall' feature used to
     force MINUIT to retreat from regions with evaluation errors

   - Enlarge default size of box created by paramOn()

 
 o RooAbsArg

   - 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

   - In constant term optimization, prevent addition of 
     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

   - Add Silence() named argument to ctor that will silence all
     RooFit messages during running below the PROGRESS level

   - Store generated number of events in fitParDataSet()

     fit and/or generator model used.


 o RooNumRunningInt

   - Fix bug in calculation of cdfs.
    

 o RooMinuit

   - Deprecate support for error handling mechanisms that are now
     phase out.

   - Implement option to ignore evaluation errors   

   - Improve the contour() method to return a RooPlot containing
     contour TGraphs, rather than drawing them directory on a canvas


 o RooDouble

   - Set name to string representation of value


 o RooGlobalFunc

   - Add various named argument constructors needed by other code


 o RooCintUtils

   - New name space with CINT interaction utilities

   - Add function to match a given functin pointer to a string with
     a function argument list specification to facilitate manual overloading
     of method on function pointer declarations, which is not supported
     directly by CINT

   - Introduce printAddress() method to print address


 o RooRandomizeParamMCSModule

   - Fix bug in init()


 o RooAcceptReject

   - Adjust code to make it work with observables with parameterized ranges

   - Add method to calculate confidence intervals for efficiency binomials.


 o RooSentinel

   - Add cleanup handler for expensive object cache global instance


 o RooBinningCategory

   - New real->cat function that represents binning associated with
     any given RooAbsRealLValue as category functions. Category states
     mapping to observable bins are automatically created and named


 o RooSimultaneous

   - Add support for new Slice() arguments that allow to specify the
     slice position for category observables.

Import changes from development branch

==== Date: Wed Feb 20 22:33:28 2008 =====

   o RooRealSumPdf

     - Do _not_ use normalization of RooAbsPdf input components
       in numerator of RooRealSumPdf expression since it is 
       already explicitly occurring in denominator of RooRealSumPdf.
       (Fixes wrong normalization reported by Tristan)


   o RooObjCacheManager

     - Register owner of cache with each cache elememt to
       facilitate callbacks


   o RooAbsCacheElement

     - Add storage for pointer to owner of cache and
       supply setOwner() function


   o RooAbsPdf

     - Use RooObjCacheManager callback mechanism to zero
       'last used normalization' pointer in RooAbsPdf
       when the cache-owned object pointed is about
       to be deleted. 


   o RooAbsArg

     - Make crc32 function static


   o RooWorkspace

     - Add CodeRepo nested class that allows to store C++ code
       of RooAbsArg derived classes that are not in ROOT distribution
       but are contained in workspace. When reading any missing
       class, code is compiled on the fly allowing for transparent
       reading of workspace object from file. Code is found in
       location pointed to from TClass objects. Additional search
       path for declaration and implementation files can be provided
       to be able to handle non-trivial cases.

     - Add WSDir nested class that represents information contained
       in workspace as read-only TDirectory for easy interactive use. 
       Directory representation is created using makeDir() member function.


  o LinkDef3

     - Add nested classes in RooWorkspace

===== Date: Wed Mar 26 23:04:26 2008 =====

   o RooProdPdf

     - Fix typo in ctor documentaion

     - Improve error message in expectedEvents() when no extendable p.d.f.s are found

     - Implement getConstraints() function to retrieve constraint p.d.f terms from product
       expression given set of observables and set of parameters to be constrained.


   o RooMsgService

     - Add PROGRESS message level between INFO and WARNING

     - Add globalKill level for messages to be able to quickly eliminate all messages below
       a given level without interfering with the stream structore of RooMsgService


   o RooPrintable

     - Implement new printing interface with more details control over items printed trhough contents enum
       (multiple ORable options) and style of printing (inline, single line, (verbose) multiline) with style 
       enum (exclusive options). 

     - Introduce generic virtual functions for printing of name,title,value,arguments,
       and extras of each object. 

     - Each class can overload the default contents used for all printing
       uses (inline,verbose,standard) etc as well as the default printing style invoked by Print()


   o RooPlot,RooGenContext, RooAbsRealLValue,RooDataSet,RooNameSet,RooCustomizer, RooAbsGenContext, RooAddModel,
     RooFitResult,RooCurve,RooAbsAnaConv,RooHist,RooAbsReal,RooAbsCollection,RooAddPdf,RooTable,RooAbsData,
     RooMappedCategory,RooFormula,RooFormulaVar,RooCatType,RooRealVar,RooAbsArg,RooAbsPdf,RooPlotable,RooRealIntegral,
     RooAbsBinning,Roo1DTable,RooAddGenContext,RooGenericPdf,RooResolutionMode,RooAbsHiddenReal,RooMultiCategory,
     RooAbsString,RooSetProxy,RooProdGenContext,RooConvGenContext,RooGenCategory,RooGrid,RooSimGenContext,
     RooThresholdCategory,RooAcceptReject,RooSuperCategory,RooEllipse,RooNumIntConfig,RooAbsCategory,RooListProxy,
     RooLinearVar,RooTreeData,RooTreeData

     - Update to new RooPrintable interface


   o RooGenContext,RooAbsGenContext,RooAddGenContext,RooProdGenContext,RooConvGenContext,RooSimGenContext

     - Implement attach() function to simplify management of changing parameters during lifetime of context


   o RooAbsRealLValue

     - Eliminate inFitRange() warning message as it is gives too many false warnings when used with
       parameterized ranges


   o RooCustomizer

     - Make owning of contents optional to simplify release of created components
     

   o RooAbsReal

     - Implement new evaluation error logging mechanism. Rather than passing zero p.d.f values, push error message with
       details on a static stack (if logging is enabled by e.g. RooMinuit). 

     - Augment functionality of createIntegral: explicitly allow integration over ranges with bounds parameterized in 
       in terms of other integrated observables. Integrals of this type are automatically recognized and cast
       as recursive integrals in case of >1-D integrals to integrate over requested phase space. 

     - Add createIntObj() helper function for above functionaliy.

     - Eliminate a lot of commented out debug code from createPlotProjection()

     - Modify fillHistogram(): when plot observables are cloned, explicitly interconnect clones again to facilitate
       proper plotting of N-D integrals with entangled parameterized ranges

     - Add ScaleFactor() argument to fillHistogram to control use of histogram density correction scale factor in Z-scale
       of filled histogram


   o RooProduction

     - Fix bug for persistence


   o RooRealMPFE

     - Extend client/server protocol with message to retrieve RooAbsReal evaluation error log from server side and
       merge with error log on client side


   o RooRealVar

     - Introduced concept of non-shared alternative binnings(ranges) required to accommodate RooParamBinning ranges
       that cannot be shared across instances because of their client/server connection to other objects in p.d.f
       expression trees. Modify setBinning to automatically recognize non-shareable binnings and divert those to
       non-shared alternative binning container.

     - Add setRange([const char*,] RooAbsReal&,RooAbsReal&) methods to simplify creation of parameterized ranges.


   o RooAbsArg

     - Introduce concept of owned components with addOwnedComponents() interface to be able to make any RooAbsArg
       object own any number of others. This can be used to simplify the memory management of object trees 

     - Introduce prohibitServerRedirect mode that will trigger fatal assert if any server redirect is attempted
       to thus configured object. Useful as debugging tool to track faulty copy constructors that leave clone
       object tree unintentionally connected to the original object tree.

     - Migrate fixed--name-field management tool from RooAbsReal to RooAbsArg. Used to accomplish regular
       formatting in RooAbsCollection::printStream.

     - Add concept of transient boolean attributes that are not tranferred on copy construction. Mostly useful
       for debugging.

     - Extend leafNodeServerList and treeNodeServerList to distinguish to types of leaf-nodes: strict leaf modes
       in the sense of the client-server tree structure and 'physical' leaf nodes that do not recurse into
       nodes that have isDerived()==kFalse. The latter corresponds to the original concept of leaf nodes / variables,
       which the former mode, a new addition, explicitly exposes any shape servers contained in parameterized
       ranges of variables.

     - Fix logic error in recursiveServerRedirect: do not recurse into nodes that are in the replacement list themselves.

     - Fix bug in printCompactTree(): value/shape clients were not always properly indicated.

     - Add getAllConstraints() method that finds all RooProdPdfs in expression trees and harvest constraints from all
       of these from the getConstraint() method


   o RooAbsPdf

     - Implement new evaluation error logging mechanism for negative p.d.f values and zero normalization integrals

     - Add Constrain(const RooArgSet& pars) and ExternalConstraints(const RooArgSet& pdfs) arguments to fitTo() method.
       The Constrain() method retrieves any constraints p.d.f. on parameters multiplied in any RooProdPdf in the normal 
       p.d.f expression and adds those to the likelihood that is minimized. Only constraints on the listed parameters
       will be picked up. Multiple constraints per parameter may exist. The ExternalConstrains() argument implements
       similar functionality except that provided external constraint p.d.f.s are added rather than internal constraints.

     - Fix potentially fatal bug in print statement in getContext()

     - Add new method createCdf() to create a cumulative distribution function from given p.d.f. Given a set of observables x, 
       the returned c.d.f is implemented in terms of a RooRealIntegral of p.d.f(x') over a parameterized range from [ 0 - x ].


   o Roo1DIntegrator

     - Improve error message


   o RooRealIntegral

     - Fix bug in calculation of shape dependencies on observables.

     - Add handling of dependencies of integral value on values of objects representing parameterized ranges of
       integrated observables.     


   o RooMCStudy

      - Add Constrain(const RooArgSet& pars) and ExternalConstraints(const RooArgSet& pdfs) arguments to constructor.
        In addition to passing these arguments to the fitTo() call of the fit stage, modify event generation as
        follows: instead of sampling events from 'static' generator p.d.f, sample value of constrained parameters
        from joint constraints p.d.f and sample observables at those parameter settings. Save the generator parameters
        for each toy as these change per toy. Change the pull calculation such that it uses the per-event truth values
        rather than the per-study truth value if constraints are used.


   o RooAddition

     - Fix bug in evaluate() related to persistence


   o RooMinuit

     - Enable/disable new evaluation error logging mechanism prior to and just after each MINUIT call.

     - Print logged error messages, if any, in glue function


   o RooProjectedPdf

     - Fix important bug: normalization set should always include integration set for each configuration


   o RooGlobalFunc

     - Add definition of Scaling(),Constrain() and ExternalConstraints() helper functions 


   o RooUniformBinning
  
     - Remove dedicated print function as it output is identical to that of the generic print function in RooAbsBinningx

  
   o RooAbsBinning

     - Add virtual methods isParameterized(),lowBound() and highBound() to be to detect and analyze parameterized binnings
       through abstract interface

     - Add isShareable() method to be able to separate shareable and non-shareable binnings in RooRealVar.

     - Add insertHook() and removeHook() function to allow connection of possible proxies present in binning to
       owning RooAbsArg.


   o RooWorkspace

     - Improve code import facility by introducing a class->file mapping step in the CodeStore to correctly handle cases where 
       multiple classes are defined in a single file.

     - Add check that TClass interface actually yields file names.

     - Only require default constructor to be present for non-abstract classes. It should be there for abstract classes as
       well but current TClass::HasDefaultConstructor() method will not tell us.

   o RooTreeData

     - Improve renameVariable() method to not only rename the RooAbsArg branch buffer but also any TTree branches involved as well.
       While the tree branch names are generally invisible to the user, having branch names that are different from branch buffer names
       may cause branch naming conflicts in merge() that are not detectable as branch buffer naming conflicts.


   o RooParamBinning

     - New class implementing binning with low and high points defined by external RooAbsReal objects 


   o RooConstrainSum

     - Helper class for RooAbsPdf to represent likelihood of collection of constraint p.d.f.s.


==== Date: Fri Mar 28 10:04:57 2008 =====

   o RooRecursiveFraction

     - Helper function for RooAddPdf that calculates recursive fraction 
       f1*(1-f2)*(1-f3) from a given set of plain fractions


   o RooAddPdf

     - Add flag to ctor to optionally interpret fractions as recursive fractions.
       If activated it constructs the recursive fractions using RooRecursiveFraction
       from the original fractions


   o LinkDef3.h, Module.mk

     - Add new class RooRecursiveFraction

==== Date: Tue Apr  1 22:42:19 2008 ====

   o RooDataWeightedAverage

     - New implementation of RooAbsOptTestStatistics that calculates data weighted
       average of any RooAbsReal. This class serves as successor of RooDataProjBinding
       that no longer complies with new optimization scheme. 

   o RooRealBinding

     - Implement name() function for more useful error messaging in integration


   o RooChi2Var,RooNLLVar

     - Follow changes in base class


   o RooAbsReal

     - In plotOn() support binning flag in ProjWData(). Reimplement data-weighted projections
       using new RooDataWeightedAverage class instead of RooDataProjBinding which does not
       work with new generic function optimization scheme. 

     - Add support for NumCPU() argument
       in plotOn() to facilitate multi-processor calculation of projections. Extend NumCPU()
       argument to pass interleaving option in MP splitting mode of RooAbsTestStatistic

     - Move fixAddCoefNormalization() and fixAddCoefRange() from RooAbsPdf to RooAbsReal
  

   o RooAbsTestStatistic

     - Generalize functionality: allow RooAbsReals as input arguments instead of RooAbsPdfs only.
       Also add virtual globalNormalization() function that allows to apply a global normalization
       term after combinedValue() operation to facilitate functionality of RooDataWeightedAverage.

     - Add option to split data in multiprocessor mode in interleave mode instead of in bulk mode.
       Interleave mode is useful for parallel processing of histogram data where bulk partitions
       may not contain equal amount of non-zero data points leading to non-optimal load balancing
       between processes.

   o RooAbsCache

    - New abstract base class for cache objects associated with RooAbsArgs.
      Caches register themselves with the owning RooAbsArg and propagate
      all necessary state changes and meta information to objects in the cache


   o RooCacheManager

    - Concrete template implementation of RooAbsCache with an interface
      and functionality styled after RooNormListManager. The template class
      provide no special handling for cache contents that includes RooAbsArg
      objects and does not forward hook calls. It is thus mostly intended
      to cache basic types indexed on a normalization/integration configuration


   o RooObjCacheManager

    - Class derived from RooCacheManager<RooAbsCacheElement> that implements
      all proper call forwarding and handling of state and other meta information
      to RooAbsArg objects embedded in the cache elements. To facilitate this
      functionality the RooAbsCacheElement defines a pure virtual method
      containedArgs() that must be implemented to expose its contents to
      the cache manager. The default behavior on a serverRedirect hook is
      to sterilize the cache. OperMode changes are not forwarded by default
      to the cache contents as cached objects do not necessarily have the
      same operation mode (e.g. if the cache contains an integral of its owner).
      Any calls to optimizeCacheMode(), printCompactTreeHook(), and findConstantNodes()
      are forwarded. Moreover, optimizeCacheMode() calls are remembered and
      any objects inserted in the cache after such a call was received will be
      optimized upon insertion in the cache

   o RooAbsCacheElement

    - Abstract base class for objects to be managed by RooObjCacheManager. Each
      object must in addition to its payload implement the containedArgs()
      member function that exposes the RooAbsArg object content to the manager
      for processing. The argument passed to containedArgs() indicates the use
      case for the returned list of objects, allowing the cache payload to
      return different lists depending upon use. This is for most applications
      not required.


   o RooAbsCachedPdf

    - Abstract base class derived from RooAbsPdf for p.d.f.s that implement 
      value caching in a grid over the entire domain of the observables. 
      The base class implements the overall caching logistics and manages
      the RooDataHists and RooHistPdfs that respresent the cached contents.
      Derived classes must inputBaseName() defined a unique name prefix for
      all cache objects, actualObservales() and actualParameters() to
      determined the actual observables and parameters given a set of 
      available observables and fillCacheObject() which should fill the
      RooDataHist cache for a given obs/params configuration with the
      p.d.fs values.


   o RooAbsSelfCachedPdf

    - Abstract base class derived from RooAbsCachedPdf that implements
      all of the required logistics in RooCachedPdf and only require
      derived classes from RooAbsSelfCachedPdf to implement evaluate().
      Any class derived from RooAbsPdf can thus be trivially switched
      to derived from RooAbsSelfCachedPdf and gain the caching functionality.
      

   o RooCachedPdf

    - Concrete class derived from RooAbsCachedPdf that implements
      the caching of an externally provided p.d.f in the constructor.


   o RooFFTConvPdf

    - Concrete class derived from RooAbsCachedPdf that implement generic
      numeric convolution of two input p.d.f.s using FFT technique
      and convolution theorem. Actual FFTs are calculated by FFTW
      through TVirtualFFT interface in ROOT. Present implementation only supports 
      convolution in one dimension, but this will be extended later
      as there are no fundamental limitations in RooAbsCachedPdf nor FFTW.
 

   o RooHistPdf

    - Moved from RooFit to RooFitCore because it is used by caching classes


   o RooProdPdf

     - Use new RooObjCacheManager to store partial objects

     - Fix memory leak (already patched in 15.0.14h)


   o RooDataHist

     - Use new RooCacheManager template to cache partial bin volumes

     - Add new set(),setAllWeights() method to update current weight and all weights
       respectively, for use in cached p.d.f.s

     - Add sliceIterator() that iterates over all bins in a lower dimensional 
       slice of the dataset


   o RooDataHistSliceIter

    - Class derived from TIterator that implements the iteration
      over a slice in a reduced number of dimensions in a RooDataHist


   o RooMsgService

     - Speed up processing of debug streams in cases where no debug streams are active

     - add macros series oocoutX and oocxcoutX that allow to associate message with
       a different object than *this

   o RooRealBinding

     - Interface new setValue method that allows value to be set outside default
       domain, but inside given alternate named range. For use in numeric integrator
       bindings


   o RooAbsRealLValue

     - Add new inRange() method with range name specifier to check against chosen
       range instead of default range


   o RooCmdConfig

     - Fix dangling return pointer problem in decodeStringOnTheFly() method


   o RooNameSet

     - Fix bug in refoll()


   o RooChi2Var, RooNLLVar

     - Add processing of AddCoefRange() named argument


   o RooConvCoefVar

     - Hold p.d.f in proxy without value/shape state propagation to obtain
       correct dependency of RooConvCoefVar through separate set proxy
       with parameters that do have state propagation

     - In getAnalyticalIntegral() ask for integration coefficient specific
       to coefficient (following interface change in RooAbsAnaConv)


   o RooEfficiency

     - Follow interface change in RooCategoryProxy


   o RooAbsAnaConvPdf

    - Use new RooObjCacheManager to hold normalization and coefficient representations

    - Extend getCoefAnalyticalIntegral() interface so that each coefficient
      can have a separate integration configuration

    - Modify makeCoefVars() such that it constructs the RooConvCoefVars with
      actual dependents for each coefficients, rather than inserting dependencies
      of any of the coefficients in each coefficient. This logic requires support
      from the implementation class that is interface through a new member function
      coefVars()


   o RooAbsReal 

    - Add Boolean data member treeVar that indicates is value buffer is also
      branch buffer of a tree. This information is already present in the RooAbsReal
      but is relatively expensive to retrieve and is always needed in the inner
      loop of data set operations. This extra member significantly speeds up operations

    - Remove superfluous _norm[] token in name returned by integralNameSuffix() if 
      no normalization set is supplied.

    - Add a fillDataHist() method that fills a given RooDataHist with a sampling
      of the given function. Added for support of caching p.d.f.s


    - Downgrading warning on non-dependent projection variables in plotOn() to
      a debug level message

    - Remove function optimizeDirty(),doConstOpt(),undoConstOpt(),findCacheableBranches()
      findUnusedDatasetVariables() and findRedundantCacheServers() as part of reorganization
      of optimization functionality.


   o RooAbsCollection

    - Use iterator semantics instead of vector semantics to process RooLinkedList
      contents in assignment operator

    - Add utility function contentsString() returning stl string with names
      of contents


   o RooAddPdf

    - Rewrite cache management using new RooObjCacheManager that holds projection
      integrals, range integrals and supplemental normalization lists


   o RooAbsOptGoodnessOfFit

    - Improve handling of normalization ranges and reference ranges for test statistics
      containing RooAddPdfs. New named argument in fitTo() and RooNllVar::ctor() pass
      reference range for fractions in RooAddPdf components that do not have an explicit
      fixed definition already. Name all normalization ranges explicitly after the
      subrange to which the're applied to avoid name clashes and conflicts if multiple
      normalization ranges are involved.

    - Rewrite informational messages through RooMsgService

    - Implement new constOptimizeTestStatistic() function that signals all test statistic
      components of a RooAbsArg expression tree to perform their constant term optimization

    - Implement new optimizeCaching() driver function that changes default lazy-evaluation-with-caching
      scheme to test statistic scheme where only parameters objects propagate state changes and
      where all components that depend directly or indirectly on observables have lazy evaluation
      disabled. Changes to p.d.f objects are delegated to RooAbsPdf::optimizeCacheMode(). Changes
      to dataset are delegated to RooAbsData::optimizeReadingWithCaching()

    - Implement new optimizeConstantTerms() function that is back end for constOptimizeTestStatistic
      implementation. 


  o RooAICRegistry, RooNormSetCache

    - Remove tracking of allocation cycles of RooArgSets as this scheme is superseded by
      memory pool mechanism for RooArgSet allocation


  o RooMappedCategory

    - Follow interface change in RooCategoryProxy.


  o RooRealMPFE

    - Follow reorganization of optimization functionality: implement new constOptimizeTestStatistic
      function for forwarding to slave processes.


  o RooRealVar

    - Add new setVal() function with range name to facilite setting of values that are outside
      default range, but inside specified alternate range. Needed for numeric integration and
      certain RooAddPdf coefficient projection.


  o RooAbsArg

    - Make state management functions public [is/set][Value/ShapeDirty](), setOperMode90
  
    - Add static _flipAClean boolean to support setACleanAdirty() static method.

    - Implement mechanism for registration of cache objects with base class RooAbsCache.
      Forward all calls to operModeHook(), redirectServersHook(), optimizeCacheMode()
      and printCompactTreeHook() to all caches for further processing
   
    - Define constOptimize() function and provide default implementation that forwards
      to all servers 

    - Implement optimizeCacheMode() function that puts expression tree in optimized
      caching for test-statistics operations (only cache/lazy evaluate nodes that
      do not (indirectly) depend on observables

    - Implement findConstantNodes() function that identifies all nodes that depend
      exclusively on constant observables and >0 observables that are eligible
      for precalculation and caching in test statistics operations by 
      RooAbsOptTestStatistic::optimizeConstantTerms()

    - Define constOptimizeTestStatistics that signal an expression tree that any
      embedded test statistic objects should perform their constant term optimization.
      Default implementation in RooAbsArg forwards call to all servers.


  o RooAbsPdf

    - Use new RooObjCacheManager to manage normalization integrals cache.

    - Process new SumCoefRange() option in fitTo() that sets the coeffient
      interpretation range for all embedded RooAddPdf objects of which
      the interpretation range was not explicitly set

    - Extend interface of fixAddCoefNormalizationSet(): add extra argument
      that controls if AddCoef normalization set are forcibly overruled
      for objects that already have an explicit range setting.

  
   o RooRealIntegral 

    - Add some informational messaging through RooMsgService, rewrite existing ones

    - Speed up numeric summations by precreating the involved RooSuperCategory
      in the ctor rather than in evaluate().

    - Fix bug in dependency insertion: explicitly require servers to be value
      server to avoid pulling in fake dependents.
    
    - Remove obsolete data members

    - Implement new setACleanADirty() function that atomically flips state of
      all AClean objects to ADirty for the duration of the integration step.
      Replaces the much more expensive prepareACleanFunc() that did this
      only for the objects involved.

    - Process factorizing terms in integral only if the list is not empty

    - Process Jacobian terms in integral only if the list is not empty


  o RooAddGenContext

   - Adapt to cache management chanches in RooAddPdf


  o RooNumIntFactory

   - Use STL classes for internal memory management


  o RooSetProxyy

   - Implement operator new() and operator() delete as required because
     RooArgSet implements them 


  o RooAbsGoodnessOfFit

   - Store and forward AddCoefRange information for embedded RooAddPdf objects

   - Implement constOptimizeTestStatistic() and forward to components


  o RooErrorVar

   - Follow inRange() interface change in RooAbsRealLValue


  o RooConvGenContext

    - 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

  o RooAbsFunc

    - Make resetNumCall() const

  o RooAbsIntegrator

    - Add calculate() method that wrape integral() between
      profiling code the track the number of integrand
      function calls

    RooSegmentedIntegrator2D,RooMCIntegrator

   - Change interface to take RooNumIntConfig class instead
     of now deprecated RooIntegratorConfig class

   - Add member function that advertise capability of the integrator:
     canIntegrate1D,2D,ND,OpenEnded()

  o RooAbsReal

   - Change normalization integral management classes
     (createIntegral(), (set)defaultIntegratorConfig(),
     (set)specialIntegratorConfig()) to work with new
     RooNumIntConfig class.

  o RooArgSet

   - Add new convenience functions get/setRealValue(),
     get/setCatLabel/Index(), get/setStringValue() to
     manage common content of RooArgSet.

  o RooConvCoefVar, RooConvGenContext

   - Support class name change RooConvolutedPdf -> RooAbsAnaConfPdf

  o RooCustomizer

   - Add function setCloneBrancSet() that allows to specify
     an external set that takes ownership of the cloned branch
     nodes so that customized objects can live beyond the lifetime
     of the RooCustomizer instance

  o RooImproperIntegrator1D

   - Add code to handle limit scenario changes (closed to open ended
     and vice versa) on the fly

  o RooIntegrator1D

     fixed number of steps w/o extrapolation. This is more robust
     for certain types of integrals

  o RooRealIntegral

   - Change interface to take RooNumIntConfig class instead of
     RooIntegratorConfig class

   - Delegate instantiation of numeric integration engines to
     new class RooNumIntFactory

  o RooNumIntConfig

   - New class to store configuration of numeric integator engines.
     This class has a brief common section with common properties
     like absolute and relative precision convergence criteria,
     and a section with implementation specific details for each
     engine in the form of a RooArgSet. The default settings for
     each existing engine are automatically added to the defaultConfig()
     instance during run-time initialization

  o RooNumIntFactory

   - Factory class for numeric integration engines. Each existing
     integrator engine automatically registers with the factory
     stating its capabilities (1D,2D,ND / Open-ended). The
     createIntegrator() function instantiates an integrator
     appropriate for a given problem. In case more than one
     integration engine can solve the given problem the (user
     changable) information in the RooNumIntConfig passed along
     with the call is used.

  o RooGaussKronrodIntegrator1D

   - New integrator engine based on Gaussian quadrature techniques.
     This implementation, taken from GSL 1.5 implements the Gauss-Kronrod
     techniques where the error on the integral is take from the difference
     between the Gauss and Kronrod techniques. These techniques share common
     sampling points allowing to calculate the error without additional cost.
     This integrator applies the 10,21,43, and 87 point rules in succession
     until the desired accuracy is reached. Open-ended integrals are
     automatically handled through a x -> 1/x coordinate transformation

  o RooAdaptiveGaussKronrodIntegrator1D

   - New integrator engine based on Gaussian quadrature techniques.
     This implementation, taken from GSL 1.5 implements the Gauss-Kronrod
     techniques where the error on the integral is take from the difference
     between the Gauss and Kronrod techniques. These techniques share common
     sampling points allowing to calculate the error without additional cost.
     This integrator applies the 10,21,31,41,51 or 61 point rule and
     recursively subdivides the integration domain until the desired accuracy
     is reached. For integrands with integrable singulaties the Wynn epsilon
     rule can be selected to speed up the converges of these integrals. Open
     ended integrals are automatically handles through a x -> 1/x
     coordinate transformation

  o RooNumConvPdf

    - New operator PDF class that implements numeric convolution of
      any two PDFs. The calculation of the convolution integrand
      is implemented in the auxiliary class RooConvIntegrandBinding,
      which in turn can be integrated with any 1-D numeric integration
      engine. The default integration method for convolution integrals
      is the adaptive Gauss-Kronrod method, which appears to give the
      most stable results. By default the integration is performed
      from -inf to +inf, but can optionally be restricted to a sliding
      window using the setConvolutionWindow class, useful for relatively
      narrow resolution PDFs.

  o RooAbsAnaConvPdf

    - New name of RooConvolutedPdf to clearly distinguish its functionality
      from RooNumConvPdf

  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.
