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
