! 20010706 GaudiKernel v10

- Changes in interfaces needed for improved interactivity support :
  IService.h   : Added new method reinitialize() to allow services to 
                 take into account changes after the first time initialization
  IAlgorithm.h : Added beginRun() and endRun() methods. These are called each time
                 the event loop is executed.
  IEventProcessor.h : Added executeRun() and nextEvent() methods. This is to 
                      eliminate the need to use the IAppMgrUI interface in the
                      EventLoopMgr components.
  IAppMgrUI.h  : Renamed method state() to stateName().
  IScriptingSvc.h : Deleted
 
- Changes in support classes for transient data stores 

  Bootstrap.h/cpp : Allow to set the instance of the service locator
                    in case several ApplicationMgr instances are present.
  ObjectVector.h,
  ObjectList.h    : Add forward typedefs for pointer and const_pointer
                    (Requested by P.Calafiura/LBL)
  RefTable.h      : Implement serialize methods
  RegistryEntry.h/cpp,
  DataSvc.h/cpp   : Implement several bug-fixes
                     - allow for objects in locations like /AA/BB/BB/BB/...
                     - allow to access objects with omission of the root
                       directory: "/Event/MC" is equivalent to "MC"
                     - execution optimization
  SmartDataObjectPtr.h : Fix annoying compiler warning
  SmartRefBase.h,
  SmartRef.h      : operator==() was badly implemented (Found by O.Callot)
  strcasecmp.h    : WIN32 needs an additional #include <cstring> 

- Added remote properties functionality. Changed PropertyMgr and base classes Service
  and Algorithm
- Added MsgStream::endmsg with same functionality as endreq. (Request from ATLAS)
- Using AIDA Historams instead of LHCb private ones. The existing include files 
  include the new ones but generating a warning. The IAnnotation interface is added
  because it does not exists in the used AIDA release

- Fixed bug reported by M. Cattaneo. The OutputLevel of AlgTools was not
  set correctly if the parent Algorithm didn't set it explicitely.

- Allow access to data store items without specification of the top level
  directory. It is equivalent to specify an histogram like "/stat/simple/1"
  or simply "simple/1". Note that the the entire prefix "/stat/" must be 
  omitted. The use is backwards compatible.

- Added a qualifier ALWAYS to the message service specifying that a given 
  message should always be printed.
  ie.
  MsgStream log (msgSvc(), "Name")
  log << MSG::ALWAYS << "Hello." << endreq;
  will result in
  Name      SUCCESS Hello.
  and will not be omitted.

- Bug fixes:
  GaudiKernel/DllMain.icpp WINNT: Processhandle should no longer be closed
                           since the handle is shared for all DLLs.
  GaudiKernel/INTuple.h    Interface extended to directly use NTuple pointer
                           to write/read n-tuple. It is no longer necessary to
                           use the n-tuple service for these actions.
  NTupleImplementation.h/cpp dto.
  GaudiKernel/SmartDataPtr.h        Bug fix: 
                                    SmartDataPtr<Object> obj (...)
                                    if ( obj ) {...}
                                    Check succeeded if object is present however
                                    had bad type. Now this check checks for the
                                    presence of the object AND the data type.
                                    Moved pointer to object from SmartDataObjectPtr
                                    to SmartDataStorePtr (template class).
                                    Also moved corresponding check operators.

! 20010706 GaudiSvc v6

- Bug Fix in JobOptions. Scientific notation in floats/doubles is now working correctly
- Fixed problem "Gaudi jobs do not fail if the job options service fails 
  to set an option" CT0000000060711 by M. Cattaneo
- Fixed bug on Histograms projections introduced when going to AIDA

- Minor bug fixes to logic for the interactivity support (scripting).
- Minor tweaks to avoid warning messages with gcc 2.95.2.

- Number of changes needed for the interactivity support (scripting)
  the ApplicationMgr and EventLoopMgr make use of the newly added method 
  reinitialize()  to take into account changes in the configuration done
  by the user interaction like adding new services or algorithms. These
  new components are initialized in the reinitialize() method.
- Deleted GaudiEventLoopMgr class and moved its functionality to EventLoopMgr.
- Implemented IEventProcessor::executeRun() in ApplicationMgr and EventLoopMgr
  to call beginRun() and endRun() to all Algorithms.
- Callbacks (handlers) in AppicationMgr to support scripting have been simplified.
- HistogramSvc implements reinitialize()

- ChronoStatSvc : modification for improved printout 

- Dll/GaudiSvc_Load.cpp : Add new factory for event tag collections
  NTuples/*             : update to separate event tag collections from 
                          NTuples. NTuple persistency is now completely 
                          steered by the option 
                          ApplicationMgr.HistogramPersistency 
                          See mail of D.Rousseau in GAUDI_DEVELOPERS
- PersistencySvc/EvtCollectionStream.cpp
                          Update for separation of NTuples and
                          event tag collections

- Modified HistogramSvc to use the AIDA interfaces (1.0). This required quite a lot 
  of changes due to the fact that setTitle() method was not definied. Instead the
  IAnnotation has been used.

- Allow Histograms and N-tuples to be booked without the top level directory
  ie. without always specifying "/stat/....". The specification of an histogram
  such as "/stat/simple/1" is now equivalent to "simple/1". The use of 
  histograms and N-tuples is backwards compatible.

- NTupleSvc/NTupleSvc.cpp                    Simplification using changes in
                                             GaudiKernel v10
- EventSelector/EventSelectorDataStream.cpp  Recognize SICB file type also for
                                             specs like:
                                             "DATAFILE='xxx.dat' TYP='SICB'"
                                             is now equivalent to 
                                             "FILE='xxx.dat'"

- Fixed bug concerning histograms being saved to disk before Algoritms are 
  finalized, reported by Stefan Piperov (HARP). Changed GaudiEventLoopMgr.cpp

! ============================================================================
! 20010706 HbookCnv v10

- Introduced new option to Hbook histogram persistency service
  to steer the handling of row-wise N-tuples, because many people 
  complained about the additional column in the N-tuple.
  The following options are possible:
  Note: New DEFAULT is FLOAT_ONLY.

  // Old style (uses the additional column - backwards compatible)
  HistogramPersistencySvc.RowWiseNtuplePolicy = "USE_DATA_TYPES";
  // Save and retrieve all variables as NTuple::Item<float> ONLY
  HistogramPersistencySvc.RowWiseNtuplePolicy = "FLOAT_ONLY";
  // Fortran: IMPLICIT REAL*4 A-H,O-Z
  //          IMPLICIT INTEGER*4 I-N
  HistogramPersistencySvc.RowWiseNtuplePolicy = "FORTRAN_STYLE";
  // Hungarian notation: Use variable name to determine type
  // (first and possibly second char)
  // Bxxx -> bool
  // Cxxx -> char
  // Ixxx -> int
  // UIxxx-> unsigned int
  // Fxxx -> float etc.
  HistogramPersistencySvc.RowWiseNtuplePolicy = "HUNGARIAN_STYLE";

- Fixed problem that histogras and NTuples could not have the same ID
  HbookDef.h             Add declaration for HRESET
  HConverter.h/cpp       Common base class now for NTuples & Histograms.
                         Proper RZ directory handling for both
                         RZ and //PAWC objects. Histograms now 
                         temporarily go to the //PAWC/stat/... directory
                         instead of being created in //PAWC, which caused
                         clashes.
  H1DCnv.h/cpp
  H1DVarCnv.h/cpp
  H2DCnv.h/cpp           Adjusted to make use of base class HConverter, 
                         including proper directory handling.
  DirectoryCnv.h/cpp     Nearly dummy; uses base class HDirectoryCnv
  PersSvc.cpp            Cosmetics

- Changed to use the AIDA interfaces. The IAnnotation is used to obtain the histogram
  title and histogram id.

! 20010706 GaudiDb v4

- DbBaseConverter.cpp : Enhanced error printing in case of failures

! ============================================================================
! 20010706 GaudiRootDb v4

- Updated for use of ROOT version 3.01

! ============================================================================
! 20010706 SIPython v2

- Modify logic to only execute the AppMgr.JobOptionsPath script
  if none is explicitly specified _and_ the AppMgr.JobOptionsType
  is set to NONE.
- Changed to use the IRunable interface. 
- Getting the startup script from the ApplicationMgr options

! ============================================================================
! 20010706 RootHistCnv v4

- Changed to use AIDA interfaces
- Modified to not create a directory (/stat) if histograms are at top level
- Updated for use of ROOT version 3.01
