-Change the return type of TTree::Fit and TTree::UnbinnedFit from Long64_t to Int_t
to be consistent with the return type of TH1::Fit and TGraqph::Fit.
-TTree::Fit and TTree::UnbinnedFit have now the following return status:
The function return the status of the fit in the following form
fitResult = migradResult + 10*minosResult + 100*hesseResult + 1000*improveResult
The fitResult is 0 is the fit is OK.
The fitResult is negative in case of an error not connected with the fit.
The number of entries used in the fit can be obtained via
mytree.GetSelectedRows();
If the number of selected entries is null the function returns -1

Change fSelectorUpdate from Bool_t to TSelector* to hold the value
of the selector being processed so that UpdateFormulaLeaves can update it
instead of blindly update the possibly
idle fSelector __and__ the possibly invalid (because of file reload)
fSelectorFromFile. (This resolves the crash in roottest/root/tree/selector)

From Anna:
Extend the functionality of TEntryList and add the following info in TTree::Draw
// Saving the result of Draw to a TEventList or a TEntryList
// =========================================================
// TTree::Draw can be used to fill a TEventList object (list of entry numbers)
// instead of histogramming one variable.
// If varexp0 has the form >>elist , a TEventList object named "elist"
// is created in the current directory. elist will contain the list
// of entry numbers satisfying the current selection.
// If option "entrylist" is used, a TEntryList object is created
// Example:
// tree.Draw(">>yplus","y>0")
// will create a TEventList object named "yplus" in the current directory.
// In an interactive session, one can type (after TTree::Draw)
// yplus.Print("all")
// to print the list of entry numbers in the list.
// tree.Draw(">>yplus", "y>0", "entrylist")
// will create a TEntryList object names "yplus" in the current directory
//
// By default, the specified entry list is reset.
// To continue to append data to an existing list, use "+" in front
// of the list name;
// tree.Draw(">>+yplus","y>0")
// will not reset yplus, but will enter the selected entries at the end
// of the existing list.
//
// Using a TEventList or a TEntryList as Input
// ===========================
// Once a TEventList or a TEntryList object has been generated, it can be used as input
// for TTree::Draw. Use TTree::SetEventList or TTree::SetEntryList to set the
// current event list
// Example1:
// TEventList *elist = (TEventList*)gDirectory->Get("yplus");
// tree->SetEventList(elist);
// tree->Draw("py");
// Example2:
// TEntryList *elist = (TEntryList*)gDirectory->Get("yplus");
// tree->SetEntryList(elist);
// tree->Draw("py");
// If a TEventList object is used as input, a new TEntryList object is created
// inside the SetEventList function. In case of a TChain, all tree headers are loaded
// for this transformation. This new object is owned by the chain and is deleted
// with it, unless the user extracts it by calling GetEntryList() function.
// See also comments to SetEventList() function of TTree and TChain.
//
// If arrays are used in the selection critera, the entry entered in the
// list are all the entries that have at least one element of the array that
// satisfy the selection.
// Example:
// tree.Draw(">>pyplus","fTracks.fPy>0");
// tree->SetEventList(pyplus);
// tree->Draw("fTracks.fPy");
// will draw the fPy of ALL tracks in event with at least one track with
// a positive fPy.
//
// To select only the elements that did match the original selection
// use TEventList::SetReapplyCut or TEntryList::SetReapplyCut.
// Example:
// tree.Draw(">>pyplus","fTracks.fPy>0");
// pyplus->SetReapplyCut(kTRUE);
// tree->SetEventList(pyplus);
// tree->Draw("fTracks.fPy");
// will draw the fPy of only the tracks that have a positive fPy.
//
// Note: Use tree->SetEventList(0) if you do not want use the list as input.

*****************WARNING*****************
With this mega patch, we introduce support for TTree/TChain with more than
2 billion entries. Several class data members have been changed from
Int_t (or Stat_t) to Long64_t.
==>Trees written with this new version cannot be read with older versions
******************************************
TBranch:
========
- replace the members with type Int_t or Stat_t by Long64_t
Long64_t fEntryNumber; // Current entry number (last one filled in this branch)
Long64_t fReadEntry; //! Current entry number when reading
Long64_t fEntries; // Number of entries
Long64_t fTotBytes; // Total number of bytes in all leaves before compression
Long64_t fZipBytes; // Total number of bytes in all leaves after compression
Long64_t *fBasketEntry; //[fMaxBaskets] Table of first entry in eack basket
- corresponding changes in the member functions
virtual Int_t GetEntry(Long64_t entry=0, Int_t getall = 0);
virtual Int_t GetEntryExport(Long64_t entry, Int_t getall, TClonesArray *list, Int_t n);

From Philippe:
This patch implements support for TTree Friend in the new TTree Proxy
mechanism (See releases notes of ROOT 4.00/08).
For example with the result of tutorials/treefriend.C and the macro print.C:
void print() {
cout << "Entry #" << fChain->GetReadEntry()
<< " and #" << TF.GetReadEntry() << " \t"
<< x << " "; // from the main tree
if (TF.GetReadEntry()>=0) cout << TF.x; // from the friend tree
else cout << "N/A";
cout << endl;
}
You can simply create a Proxy based TSelector with
T->MakeProxy("withfriend","print.C","","nohist");
Then use the resulting file (withfriend.h) as anyother
TSelector script. For example:
T->Process("withfriend.h+","",20);
Or you can generate a simple histogram 2 files fill.C and fillCut.C
root [5] .! cat fill.C
double fill() {
return x - TF.x;
}
root [6] .! cat fillCut.C
Bool_t fillCut() {
return TF.GetReadEntry()>=0;
}
and you can just do:
T->Draw("fill.C+","fillCut.C");

From Philippe:
This introduces the implementation of MakeProxy and Draw of a C++ function which
is run in a context where the name of the branches can be used as a C++ variable.
In TTree, we added a method MakeProxy and modified the behavior of TTree::Draw
(by modifying TTreePlayer::DrawSelect).
In TTreePlayer we added TTreePlayer::MakeProxy and TTreePlayer::DrawScript
TTreeProxyGenerator is a new class implementing the generation of the skeleton.
(TBranchProxyDescriptor and TBranchProxyClassDescriptor are helper class).
A priori the tree parsing done by TTreeProxyGenerator could be used to
re-implement improved an improve MakeClass/MakeSelector.
TBranchProxy is the base class of a new hierarchy of classes implementing the
indirect access to the branch of a TTree. The main features are
- protection against array out-of-bound
- on-demand loading of branches
- ability to use the 'branchname' as if it was a data member.
For example with Event.root:
Double_t somepx = fTracks.fPx[2];
somepx is updated with the current fPx of the 3rd track.
TTree::Draw as been updated so that upon seeing
tree->Draw("h1analysis.C+","")
tree->Draw("h1analysis.C+","h1analysisCut.C")
If h1analysis.C (and h1analysisCut.C in the 2nd case) are readable files,
the new MakeProxy will be used __instead of__ TTreeFormula. Currently
TTreeFormula and 'TBranchProxy' can not be used together.
In which case the means of parameters to TTree::Draw are more like:
Int_t TTree::Draw(const char *filename, const char *cutfilename,
Option_t *option="",
Int_t nentries=1000000000, Int_t firstentry=0);
Both files are expected to be source file which contains at least a free
standing function with the signature:
x_t filename();
and
y_t cutfilename();
x_t and y_t needs to be type that can convert respectively to a double
and a bool (because the code does; if(cutfilename()) htemp->Fill(filename());
The 2 free standing function are run in a context such that the branch names
are available as locally avaiable variable of the correct (read-only) type.
If 'filename' is suffixes with an ACLiC mode, the ACLiC mode is inforced
(Note that at this time, interpreted mode is not supported and if no ACLiC
mode is specified, a '+' is used by default).
The generated script file (currently generatedSel.h but subject to change in
a future release) is intentionally __not__ deleted at the end of the processing.
Also if the file already exist, it is updated if and only if the new version
is different. In particular this means issues twice in a row:
tree->Draw("Script.C+");
does __not__ result in a second (useless) compilation.
For example to draw px in hsimple.root just have a hsimple.C file:
double hsimple() {
return px;
}
and do:
new TFile("hsimple.root")
tree = ntuple
draw(tree,"hsimple.C");
or
draw(tree,"hsimple.C+");
I attached a few examples, including a full port of the h1analysis tutorials.
To use the h1analysis do:
TChain chain("h42");
chain.Add("$H1/dstarmb.root"); // 21330730 bytes 21920 events
chain.Add("$H1/dstarp1a.root"); // 71464503 bytes 73243 events
chain.Add("$H1/dstarp1b.root"); // 83827959 bytes 85597 events
chain.Add("$H1/dstarp2.root"); // 100675234 bytes 103053 events
chain.Draw("h1analysis.C+","h1analysisCut.C");
h1analysis_Terminate();
I also have an example working of all the new Event files:
new TFile("Event.new.split9.root");
TTree * tree = (TTree*)file->Get("T");
tree->Draw("script.C");
script0.C needs to be used for Event.new.split0.root.
Also you can just generate the skeleton by doing:
tree->MakeProxy("mysel",scriptfilename,cutfilename,splitLevel);
Where the non-split branches, will be made to look as if there were
split up to 'splitLevel'. (i.e mean that their data members will
be syntactically available as if they were split).

From Philippe:
This update makes any selector created by the TTreePlayer directly from a source file local to the current TTreePlayer
object (instead of being a static).
It also insures that TProofPlayer and TTreePlayer do not call delete for an object of
a class which library was unloaded (since the code is gone, this would lead to a core
dump).

Implement support for 4 dimensions in TTree::Draw.
When doing tree.Draw("x:y:z:u"), the variable "u" is mapped to a color number.
A 3-d scatter plot is generated with ncolors TPolymarker3D objects attached
to the produced histogram list of functions.

From Philippe:
This patch solves 2 problems.
If a simple tree was made the friend of a chain, the simple tree was loaded using the 'entry in the tree (inside the
chain)' instead of the 'entry in the chain'. This resulted in ONLY the first part of the simple tree to be used (over
and over again)!
TTree::Scan (Query and CopyTree) could not handle the case where a TChain was made a friend of a TTree (and problably
more cases of uneven length chain friends). This was
because, it never detected that a new file was open since it only looked a the main Tree (and none of its friend). In
consequence the formula were not updated when they should.

Important restructuring of the TTreePlayer class in view of PROOF.
In particular TTree::DrawSelect is reduced to a few lines to use
the new TSelectorDraw class via TTreePlayer::Process.
More changes are foreseen to use the same mechanism for TTree::Scan
and TTree::Query.

This pacth from Philippe adds:
- Support for 2D graphical Cuts for TClonesArray members
- Support for 1D graphical Cuts by using their X minimum and
maximum as ( Xmin <= Formula <= Xmax ).
- Support for the following TTreeFormula special functions.
Entry$ : return the current entry number (== TTree::GetReadEntry())
Entries$ : return the total number of entries (== TTree::GetEntries())
Length$ : return the total number of element of this formula for this
entry (==TTreeFormula::GetNdata())
Iteration$: return the current iteration over this formula for this
entry (i.e. varies from 0 to LENGTH$).
- Synchronization of the dimensions of all the formulas involved in
a Draw call.
For example for (with fMatrix[4][4] and fTracks[fNtrack].fVertex[3]
T->Draw("fMatrix","fVertex>=2");
The corrected result is histogram use something like:
if (fTracks[0].fVertex[0]>=2) fMatrix[0][0];
if (fTracks[0].fVertex[1]>=2) fMatrix[0][1];
if (fTracks[0].fVertex[2]>=2) fMatrix[0][2];
if (fTracks[1].fVertex[0]>=2) fMatrix[1][0];
if (fTracks[1].fVertex[1]>=2) fMatrix[1][1];
if (fTracks[1].fVertex[2]>=2) fMatrix[1][2];
....
The old behavior was:
if (fTracks[0].fVertex[0]>=2) fMatrix[0][0];
if (fTracks[0].fVertex[1]>=2) fMatrix[0][1];
if (fTracks[0].fVertex[2]>=2) fMatrix[0][2];
if (fTracks[1].fVertex[0]>=2) fMatrix[0][3]; // note the extra step here.
if (fTracks[1].fVertex[1]>=2) fMatrix[1][0];
if (fTracks[1].fVertex[2]>=2) fMatrix[1][1];
....

W A R N I N G !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
==================================================================
A very long list of changes in this pre-release of version 3.00.
We have modified the signature of many functions (in particular TObject)
to introduce more constness in the system.
You must change your code if your class derives from TObject and uses
one of the modified functions such as ls, Print, Compare, Hash, etc.
The modified functions in TObject have the following signature:
virtual TObject *Clone() const;
virtual Int_t Compare(const TObject *obj) const;
virtual void Delete(Option_t *option=""); // *MENU*
virtual void DrawClass() const; // *MENU*
virtual void DrawClone(Option_t *option="") const; // *MENU*
virtual void Dump() const; // *MENU*
virtual TObject *FindObject(const TObject *obj) const;
virtual char *GetObjectInfo(Int_t px, Int_t py) const;
virtual ULong_t Hash() const;
virtual void Inspect() const; // *MENU*
virtual Bool_t IsEqual(const TObject *obj) const;
virtual void ls(Option_t *option="") const;
virtual void Print(Option_t *option="") const;
A similar operation has been done with classes such as TH1, TVirtualPad,
TTree, etc.

Implement interface between trees and the principal components analysis class
TPrincipal.
The user interface is in TTree::Principal that calls the TTreePlayer::Principal
function. The specs of this interface are:

{
//*-*-*-*-*-*-*-*-*Interface to the Principal Components Analysis class*-*-*

Implement the new function TTree::Process and the corresponding function(s)
in TTreePlayer.
The main function in TTreePlayer is
TTreePlayer::Process(TSelector *selector, Int_t nentries, Int_t firstentry)
This new function exploits the new class TSelector to initialize, select,
analyze and terminate the user code referenced by the selector.
This function is now called by
TTreePlayer::Process(const char *filename, Int_t nentries, Int_t firstentry)
The code in the class derived from TSelector may be interpreted or compiled.

virtual Int_t Process(const char *filename, Option_t *option=""
,Int_t nentries=1000000000, Int_t firstentry=0); // *MENU*
virtual Int_t Project(const char *hname, const char *varexp, const char *selection="", Option_t *option=""

virtual Int_t Scan(const char *varexp="", const char *selection="", Option_t *option=""
,Int_t nentries=1000000000, Int_t firstentry=0); // *MENU*
The function TTree::Process is a new function:
// The code in filename is loaded (interpreted or compiled , see below)
// filename must contain a valid class implementation derived from TTreeProcess.
// where TTreeProcess has the following member functions:
// void TTreeProcess::Begin(). This function is called before looping on the
// events in the Tree. The user can create his histograms in this function.
//
// Bool_t TTreeProcess::Select(Int_t entry). This function is called
// before processing entry. It is the user's responsability to read
// the corresponding entry in memory (may be just a partial read).
// The function returns kTRUE if the entry must be processed,
// kFALSE otherwise.
// void TTreeProcess::Analyze(Int_t entry). This function is called for
// all selected events. User fills histograms in this function.
// void TTreeProcess::Finish(). This function is called at the end of
// the loop on all events.
//
// if filename is of the form file.C, the file will be interpreted.
// if filename is of the form file.C++, the file file.C will be compiled
// and dynamically loaded. The corresponding binary file and shared library
// will be deleted at the end of the function.
// if filename is of the form file.C+, the file file.C will be compiled
// and dynamically loaded. The corresponding binary file and shared library
// will be kept at the end of the function. At next call, if file.C
// is older than file.o and file.so, the file.C is not compiled, only
// file.so is loaded.
//
// The function returns the number of processed entries. It returns -1
// in case of an error.
The correesponding modifications have been made in TChain, TVirtualTreePlayer
and TTreePlayer

- Mods in TTreePlayer to reflect the numerous changes in TGraph,
TVirtualPad, TView, TLego. Most internal variables changed from
Float_t to Double_t. In particular the members, fVmin, fVmax, fV1, fV2, fV3
are now double precision arrays. The corresponding getter functions have
their return type changed accordingly. This is a backward incompatibility.

// 29 May
- Add the following note in the TPave, TPaveLabel and TPaveText constructors:
IMPORTANT NOTE:
Because TPave objects (and objects deriving from TPave) have their
master coordinate system in NDC, one cannot use the TBox functions
SetX1,SetY1,SetX2,SetY2 to change the corner coordinates. One should use
instead SetX1NDC, SetY1NDC, SetX2NDC, SetY2NDC.
28 May
- Modify THistPainter::PaintStat and PaintStat2 to use the TLatex character #pm
instead of +-
// 27 May
- Add new member functions:
Int_t TVirtualTreePlayer::GetDimension()
Int_t TTreePlayer::GetDimension()
GetDimension returns the number of dimensions in the TTree::Draw expression.
- Add new function in TTree;
void TTree::UnbinnedFit(const char *funcname ,const char *varexp, const char *selection="",Option_t *option=""
,Int_t nentries=1000000000, Int_t firstentry=0);
This function (origin Stephen Bailey) performs an unbinned fit to the
variable(s) given in varexp.
- Remove unused data member fDimension from class TTree.
- Introduce support for "Virtuality" in TLeafObject.
New data member fVirtual added and corresponding IsVirtual/SetVirtual functions.
By default, fVirtual is kTRUE.
This change allows new interesting possibilities in split mode. For example
if a member is TShape *fShape, a real object may be now of any type
derived from TShape (eg, TTUBE, TBRIK, etc).
With the previous version, the fShape object had to be of the declared
type TShape only.
When writing a TLeafObject, the class name of the object is now written in
the branch buffer by TLeafObject::FillBasket. When TLeafObject::ReadBasket
is called, an instance of the real class is built and its Streamer function
called.
This change is backward compatible. Old files can still be processed.
It is possible to set the virtuality for the branch to kFALSE via
TLeafObject::SetVirtual. Setting the virtuality to kFALSE makes
writing and reading faster and the file slightly smaller. In this case,
a TLeafObject must be of the type declared only.
- New minor changes in TGaxis (Damir Buskulic) for date/time format
in case the start time is not an integer value.
- Modify tutorial psexam.C to set the TPaveText TextFont to 61 instead of 62.
Font precision 1 bypass the TLatex logic.
- Mods in TLatex to remove the special treatment for characters ' and ".
Strings like l'#acute{e}toile are now correctly processed.
- Fix a bug in TGraph::GetFunction. (thanks Damon Spayde). The test
if (fFunctions) return 0; replaced by
if (!fFunctions) return 0;
