Fix the issues with order in which global TROOT and LLVM globals are
initialized. TROOT was initializing Cling, but Cling could not be used
yet due to LLVM globals not being initialized yet. Solution, to delay
initializing the interpreter in TROOT till after main() when all LLVM
globals are initialized. Also the global gROOT is now defined to be
a function (ROOT::GetROOT()). Looks like it works correct on MacOS X
and Linux (ld and gold).

Introduce new function TROOT::CloseFiles to be used to insure that any
files or socket is closed and deleted before any library is unloaded and/or
CINT's shutdown is started. Use this function in the few places already
using the explicit alternative and add to TApplication handling of the .q
command (to avoid the order of deletion problem that was present there)

m Axel:
Introduce cling as a regular module to ROOT. It will only be built if
cint/cling exists; configure's output does not advocate its ability to
configure for cling. TCint's dictionary will now end up in G__TCint.cxx
instead of G__Meta to allow it to be swapped with the dictionary for
TCint from cling. In the near future, ROOT will be changed so that it
doesn't require the interpreter to be called "TCint"; at least friend
declarations in TROOT and TClass prevent that for now.

In include/RConfigOptions.h define a string with all features available
in this version of ROOT as found/set in configure. This string is the same
as the one returned by "root-config --features". At run-time this feature
string is available via gROOT->GetConfigFeatures(). Using a strstr() on
this string one can quickly find out if e.g. the alien plugin was built.

Use the DirectoryAutoAdd facility for the classes:
TTree, TH1, TEventList, TEntryList, TGraph2D
(and hence their derived classes).
The instances of those classes are now added automatically
to the current directory only when Constructe'd with arguments or Clone'd
and to the directory they are read from when their are stored
directly in a TKey. [Note: the default constructor never adds
the object to the current directory]
The directory auto add can still be disabled for instance
of TH1 and TGraph2D by setting TH1::AddDirectory.
Additionally one can disable the directory auto add for
a specific class by doing:
TClass::GetClass("myclass")->SetDirectoryAutoAdd(0)
However you might want to also be able to restore the
behavior in which case you ought to do:
TClass *cl = TClass::GetClass("myclass");
ROOT::DirAutoAdd_t func = cl->GetDirectoryAutoAdd();
cl->SetDirectoryAutoAdd(0);
TROOT::ReadingObject is marked as deprecated.. It is still
set (as it was) but is no longer used by the above mention
classes.
NOTE: One side effect of this change, is that instnace
of TTree, TH1, TEventList, TEntryList, TGraph2D that are
retrieved from a TMessage (i.e. from a socket) no longer
auto register themselves to the current ROOT directory.
Add a new optional parameter to TDirectory::Append: 'replace'
If replace is true (the default is false), the Append will
first remove from the directory any existing object and
print the message:
Replacing existing OldClass: thename (Potential memory leak).
Add a new option parameter to TDirectory::CloneObject: 'autoadd'
If autoadd is true (the default), CloneObject will call the
object 'DirectoryAutoAdd' function (if any)
In TDirectory::CloneObject add support for multiple inheritance
from TObject where TObject is not the left most base class.
Fix memory leak in TGraph2D::operator= (and add TGraph2D::Clear)
Cleanup some documentation

add plugin version checking. Each library contains a static initializer of
the new TVersionCheck class that registers its version number. This
version number is checked in TSystem::Load() against the version of the
ROOT Core. In case of mismatch Load() returns -2 and prints the error:
Error in <TUnixSystem::Load>: version mismatch, /Users/rdm/root/lib/libRIO.so = 51506, ROOT = 51507
(int)(-2)
The TVersionCheck.h is included via TObject.h so it works without change
of Makefiles. A number of Module.mk's were fixed because they were using
pre-compiled headers (which include TObject.h and hence TVersionCheck.h)
while they were not linking against libCore.

WARNING!!! This is an important change.
This is the continuation of the effort to structure libCore into
independent sub-packages.
A new class TDirectoryFile is introduced. It derives from TDirectory
and takes from TDirectory all the I/O functions.
All the classes (except TROOT) deriving from TDirectory are now derived
from TDirectoryFile. TDirectory keeps the previous API for back compatibility
with several functions made virtual.
This change should be back compatible, except if the user codes creates
a file sub-directory by direct invokation of the TDirectory constructor
instead of calling TDirectory::mkdir.
Note that TMapFile is not yet fully adapted to the new scheme.

From Axel:
This patch forwards the return value for TROOT::ProcessLine*(),
implements it as a return value to TMacro::Exec(), and fixes the
constructor for TMacro(filename). The old algorithm failed e.g. for
./whatever.C ("whatever.C" would have been the file name). Make doc a
bit more explicit.

From Federico Carminati:
"I have implemented all copy and equal operators needed to silence all
warnings in AliRoot, as requested. I have implemented shallow copies as
would do the default operators synthetized by the compiler.
Most operators are protected. If users complain, you just have to move
them into the public area, but class derivation is of course supported.
It has been a terrible job, I have modified 278 files, but the changes
are backward compabile, and this goes a long way to permitting user to
use the effc++ flag with root headers."

From Gerri:
Big patch supporting query queueing on the PROOF master, interogation and
interaction with the queue. Retrieval, finalization and archival of query
results and multiple PROOF sessions. Some other fixes:
- TMacro.h, .cxx
add method Checksum to get the MD5 of the current context
(needed for optimized selector reinitialization)
- Changes needed to create and fill the list of data sets (TROOT,
TDSet, TChain, TChainProof)
- A new method TSelector::IsStandardDraw() to check if a selector
is for standard draw actions
- TEventIter: fix for the missing last update (see above)
- Few protections in TPacketizers destructors
- Fix for code conventions in TPerfStats (the other will follow)
- Occasional missing last update of the progress bar (systematically
reproduced with SetParallel(1)): all this part is quite involved
and I have found a solution which does not harm but perhaps is not
the most elegant.
- SetParallel(0): the progress bar was not working at all in such a
case, since no packetizer is involved. Still it is useful to see
that things are not stuck, so I have added some progress messages
there too. The problem is that I have not found a way to get the total
number of entries from a data set without doing all the machinery
done in the packetizer.

From valeriy Onuchin:
- new class TImagePlugin is introduced;
To add possibility to read/write new image format one needs to create
a derived class and to override two methods:
virtual unsigned char *ReadFile(const char *filename, UInt_t &w,UInt_t &h)
virtual Bool_t WriteFile(const char *filename, unsigned char *argb,
UInt_t w, UInt_t h)
... and to specify it in the root resource file:
Plugin.TImagePlugin: ps TASPluginGS ASPluginGS "TASPluginGS(const char*)"
the name of plugin file extension DLL containing an implementation of
TImagePlugin subclass
- new class TASImagePlugin that is a subclass of TImagePlugin with ASImage
specific implementations;
- new class TASPluginGS - an image plugin class that allows to create images from
PS/EPS/PDF files and to display them in TCanvas/TPad. In addition, it allows to
browse PS/EPS/PDF files with the ROOT browser.
New files:
asimage/inc/LinkDefGS.h
asimage/inc/TASImagePlugin.h
asimage/inc/TASPluginGS.h
asimage/src/TASPluginGS.cxx
graf/inc/TImagePlugin.h
icons/pdf.xpm
icons/tb_find.xpm
libAfterImage.tar.gz

Big authentication patch by Gerri:
General purpose:
Add support for 'authenticated' sockets on client side
and prepare for support of server authenticated sockets.
Main changes:
o TSocket, TPsocket:
Added support of 'authenticated' sockets: authentication
is delegated to TSocket by calling a static method
CreateAuthSocket() returning a TSocket*.
TSocket is now the only class calling TAuthenticate.
o TFTP, TNetFile, TSlave:
modified to cope with new socket authentication scheme.
o TAuthDetails replaced by TSecContext containing:
- local authentication info
- expiration time
- pointer to a security context for the method (if any)
- information for cleanup (via TSecContextCleanup)
o A list of valid TSecContext has been added to TROOT,
accessible via gROOT->GetListOfSecContexts().
o THostAuth rewritten using arrays to avoid multiple use
of 'new'; functionality extended by the addition of
several new methods.
o TAuthenticate:
- Loading of information from .rootauthrc has been optimized;
this allowed to simplify method signatures and drop several
methods. Also collection and transmission of authentication
information from TSlave to TProofServ gets simplified by the
new scheme.
- Added support for server dependent directives in .rootauthrc
- Added check for changes in .rootauthrc each time a new
TAuthenticate is instantiated, so that changes in the file
are picked-up interactively.
- Checking for an existing TSecContext (previously TAuthDetails)
has been improved
- Improved diagnostics for SshAuth
- Enlarged support for authentication method indication in protocol:
UsrPwd: rootup/proofup
SRP: roots/proofs (already supported)
Krb5: rootk/proofk (already supported)
Globus: rootg/proofg
SSH: rootsh/proofsh
UigGid: rootug/proofug
o GlobusAuth.cxx, Krb5Auth.cxx, SRPAuth.cxx
- Adapted to new class TSecContext
- Added support for improved search for reusable TSecContext
- Drop globals used to store established security contexts
(saved in TSecContext) and related methods
o Automatic creation of <RootDir>/etc/system.rootauthrc from
compilation flags; this has priority on old envs
'Rootd.Authentication' and 'Proofd.Authentication' and is
superseded by $HOME/.rootauthrc
o Automatic creation of <RootDir>/etc/system.authdaemonrc from
compilation flags; this is superseded by $HOME/.rootauthrc

From Philippe:
This patches improves the consistency of the naming convention for the TClass
of STL containers. Previous, std::vector<float>, vector<float>, etc. could be
considered as 2 different entities by part of the ROOT code. This rationalizes these
cases. It should fix all reported related bugs.

From Philippe:
This mega patch introduces a new implementation of the STL I/O
which is backward and forward compatible. In addition this is more
exactly a new implementation or an extension of the container I/O.
We are introducing a new abstract interface:
"TVirtualContainerProxy", which can be implemented to present a
proxy to any collection which the I/O (and TTreeFormula) can use
then transparently.
The TVirtualContainerProxy interface allows to the I/O system to
request some information and to execute some essential function of
the container:
what kind of object/data does it contain
does it contain pointers
how to insert data into the container
how to retrieve an array of pointer to the elements inside
how to create a collection object
how to clear the collection
how to resize the collection
how to streamer the collection (if needed)
how to calculate the sizeof the collection
how to calculate the number of elements of the collection.
Using those primitives, the I/O and TTreeFormula should be able to
access any collection. The I/O should also be able to handle the
splitting of collections that can be split (i.e. contains a single
type of object/data).
The current compromise selected between code duplication,
performance of the I/O of TClonesArray and vector of pointers and
the performance of the I/O of other containers, was to have on
function handle all collection as if they were a C-style array of
pointers to data. This implies for example that the I/O of vector
of object current passes via the construction of temporary array
of pointer. The cost of this construction is usually ~Qjust~R the
cost of calculating the addresses of the elements and assigning it
to an array element.
Registering a collection proxy will be similar to
static int dummy = GenerateInitInstance((CollectType*)0x0)-
>AdoptCollectionProxy(new CollectTypeProxy));
Follows a few details on the modifications made to some of the
files and classes.
Bytes.h:
Work around a problem in the MSVC++ 6.0 optimizer. This should
not affect other compilers.
String:
Included the std::string dictionary into G__Base2.cxx, this
insures its presence at all time.
Added a new file string.cxx holding the streamer for
std::string.
RConfig.h
Added proper ansi stream configuration for AIX, KCC
Added template specialization defect for MSVC
TBrowser
Start adding the ability to browser non TObject classes
TBuffer
To handle the reading and writing array of objects, added:
Int_t CheckByteCount(UInt_t startpos, UInt_t bcnt, const
TClass *clss, const char* classname);
Int_t CheckByteCount(UInt_t startpos, UInt_t bcnt, const
char *classname);
void ReadFastArray(void *start , TClass *cl, Int_t n=1,
TMemberStreamer *s=0);
void ReadFastArray(void **startp, TClass *cl, Int_t n=1,
Bool_t isPreAlloc=kFALSE, TMemberStreamer *s=0);
void WriteFastArray(void *start, TClass *cl, Int_t n=1,
TMemberStreamer *s=0);
Int_t WriteFastArray(void **startp, TClass *cl, Int_t n=1,
Bool_t isPreAlloc=kFALSE, TMemberStreamer *s=0);
TROOT
Enhancement to make the access to gROOT not dependent for the
library loading order. In particular we added:
ROOT::GetROOT()
which should be used instead of gROOT.
Improve support for STL. In particular, now STL containers do
have a corresponding TClass object
TRealData
Replace SetStreamer by AdoptStreamer that allow to use not only
a streamer function but also streamer object (allowing streamer
with a state for Foreign classes)
TString:
Improve streamer performance
TSystem:
More consistency of the return value of TSystem::CompileMacro
build/unix/makecintdlls.sh
Stop making the string.dll
config:
enhance sgicc makefiles
cont:
fix TBits::operator=
TClassTable now warns for duplicate only for non stl classes
TClonesArray fix a typo
gpad:
Add a new class TInspectObject to enable inspect non TObject
classes
TRootBrowser : enable inspect non TObject classes
TFormula/TTreeFormula
To enhance performance switch from using one array fOper which
contained the operation code and its arguments to using 2 arrays
fActions and fActionParams to store respectively the operation and
its parameters.
A new function Convert is used to convert old version from the
fOper to fActions. This allows cleaner coding and offer
optimization opportunities.
TTreePlayer
Start adding support in MakeClass for STL containers.
TRint/TProofServ
Insure the loading of the string support
Event.cxx
make sure to avoid memory over-write
stress.cxx
Add new parameters
stress <nevent> <style> <subbench> <portion>
if <subbench> is 1 or higher, print the benchmark results after
each test. This allows understand
which test is affect by a performance change.
portion is a binary field to indicate which test to run. This
allows to focus on a particular test.
TVirtualCollectionProxy
Abstract interface used to access any type of containers from
the I/O system and TTreeFormula. See TVectorProxy and
TEmulatedVectorProxy for examples.
TEmulatedVectorProxy
Implementation of a std::vector proxy to be able to read a
std::vector without any libraries.
TVectorProxy
Implementation of TVirtualCollectionProxy for a std::vector for
which we have the library.
TStreamerInfo.cxx
Split in 3 files: TStreamerInfo.cxx
TStreamerInfoReadBuffer.cxx TStreamerInfoWriteBuffer.cxx
All the ReadBuffer, ReadBufferClones and the new ReadBufferSTL
(similarly for WriteBuffer) have been factorized into one
function and 2 short wrappers. The new main function expect an
array of pointer to the objects (this array is most often of size
one).
TClonesArray objects pass GetObjectRef(0) to the common
ReadBuffer
vector<bla*> v pass &(v[0])
vector<bla> needs to create an intermediary array to hold the
address
This mechanism is sometimes not optimal (vector<blah>) but
allows extremely flexibly and extension. Basically, to add
support for a new container type using the StreamerInfo mechanism
(in particular allows splitting), one 'just' need to implement a
TVirtualCollectionProxy, which, in particular, will return an
array of address to the object it contains. Even std::map can be
handled with this mechanism, since, for I/O purposes, it can be
consider as a container of pairs.
Add a few optimization, including more caching via a new array
of a new struct (fComp).
Fixed a problem (re)introduced while implementing the Foreign
class CheckSum. Doing:
class Event;
f = new TFile("Event.root");
resulted in errors.
TCint
Add proper support for TClass of STL containers. Fix a memory
leak.
Add support for load TClass via a typedef.
Fix a problem with multiple inheritance
TClass
Fixed a problem (re)introduced while implementing the Foreign
class CheckSum. Doing:
class Event;
f = new TFile("Event.root");
resulted in errors.
Add a
TClass/TGenericClassInfo/TDataMember
Add support for a new interface (TVirtualCollectionProxy)
useable for STL containers or any user defined containers.
Add support for streamer with are objects (as opposed to free
standing function or methods). This allows the user a greater
flexibility in writing a streamer.
Add a few optimizations
Add CanSplit to answer the question for a whole Class (for
example some collection can not be splitted).
TClassStreamer
New class to wrap a class wide streamer
ClassStreamerFunc_t
typedef for a class wide streamer function
TMemberStreamer
New class to wrap a specific class member streamer
MemberStreamerFunc_t
typedef for a specific class member streamer function
RootStreamer
Macro to specify a free standing streamer object or function
for a class
For example:
RootStreamer(string,std_string_streamer);
TStreamerElement:
A couple of optimization/simplification.
Add support for the new STL I/O
Extend the useful
TBranchElement:
add a connection to the proper TVirtualCollectionProxy
add support for STL containers (non-split and split mode)
TTree
Make the function TTree::GetMakeClass NON-virtual for better
efficiency
Add support for STL containers
TBasket
Left (in comment) a yet unproved improvement proposed by
Victor. The preliminary tests were inconclusive performance wise
and it had (seemingly) problem with backward and forward
compatibility.
TBranch
Performance improvements
metautils
This is a new package for C++ files shared between rootcint and
meta.
It contains TClassEdit a class to help determine some property
of a class given its class name (stl, template, etc).
utils
Introduced a new file RStl.cxx to start separating rootcint in
modules.
Modified rootcint to support the new STL I/O methods.
In particular a new class RStl is in charge of doing the
generating of code for STL containers.

From valeriy Onuchin:
I updated several base and win32gdk classes.
The goals of these changes are:
- providing thread safety for CINT and canvas graphics
- improve perforamnce
The list of the changes.
win32gdk:
- new TGWin32Interpreter class introduced. Along with
redefinition of gInterpreter global that allows to have thread-safe
interface to CINT functions and methods.
- TGWin32Proxy class renamed to TGWin32VirtualXProxy and
modified in "not-radical way".
- TGWin32ProxyBase.cxx contains "howto create proxy class".
canvas thread-safety:
- locking methods added to TCanvasImp, TRootCanvas and TCanvas
classes. That prevents from simultanious canvas updating from
different threads.
The results:
- overall improvement of thread safety and stability of win32gdk version
- improved performance. benchmarks.C 15-20%, some cases (3D graphics)
more than 30%.

From Andreas Peters:
updated TGrid and related classes, and updated TAlien plugin for the AliEN grid.
To build the TAlien plugin one needs to install the AliEn client API lib.
How the basic TGrid class works with AliEn is described in the file
README/README.ALIEN.
Also provided is a Grid/AliEn controlled distribtution and startup system
for PROOF. This uses the TGridProof/TAlienProof classes and the LFN/PFN
information in the TDSet to find the AliEn sites where the data resides.
On these sites PROOF daemons (proofd) are started by AliEn (using an
interactive submission queue). Once the proofd's are running standard
PROOF is started which then connects to these proofd's. After that the
user performs his analysis, like on a local PROOF cluster.

new features in the plugin manager: constructors can now be global functions.
In the rootrc file a global function is specified by starting the ctor with
"::". Also added support for plugin macros, instead of the lib name just
use the macro name (typically myplugin.C). The macro will be searched for in
the standard macro path.
Added new default argument to TROOT::LoadMacro() to check for the macros
existence (symmetric with LoadClass()). Used by the plugin manager to check
if a macro exists.

This patch from Philippe gives the user access to the cint error code after an
attempt to 'interpret'.
In particular the following methods have one more optional
parameter:
TApplication::ProcessLine
TApplication::ProcessFile
TObject::Execute
TROOT::ProcessLine
TROOT::ProcessLineFast
TROOT::ProcessLineSync
TROOT::LoadMacro
TROOT::Macro
and
TInterpreter::Execute
TInterpreter::LoadMacro
TInterpreter::ProcessLine
TInterpreter::ProcessLineAsync
TInterpreter::ProcessLineSync
TInterpreter::ExecuteMacro
TInterpreter::Calc
and the corresponding method in TCint.
The extra parameter is a pointer to an int (or a TInterpreter::EErrorCode
when available). If this pointer is not zero, it will be used to pass
back information on the CINT error status. The result are defined
in the enum TInterpreter::EErrorCode.
This is the best method of passing the information, because some
of the methods are already returning a result and using a global
variable (i.e. TInterpreter::GetLastErrorStatus) would lead to
indescriptible confusion (remember that there can be several
nested call to ProcessLine including one 'implied' call resulting
from the command line interpretation).
In the asynchronous case, the error status is set to kProcessing until
completion. The windows part, which consist of reseting the error status
to the proper value upon completion will be implemented in a future patch.
Also LoadMacro and Macro were updated to be able to use ACLiC and
to be able to run named macro.

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.
