     - CMake configuration changes to build Gaudi with optional externals missing

       In the last days I experimented a bit with teaching Gaudi how to build when
       only ROOT, Boost and TBB are available to it. This is the result. As far as I
       can tell the code builds in the same way as the current master branch when
       all possible externals are available. (All the ones available in a full ATLAS
       offline build at least.) And I'm also able to build the project in these
       modes:
         * On Ubuntu 16.04 with the system provided Boost and TBB versions, against
       a privately built ROOT 6 version.
         * On macOS Sierra against privately built Boost, ROOT and TBB versions.
       Both when building the project completely on its own, and when building it
       against an ATLAS externals project.
        Some notes:
         * The code uses C++14 expressions in quite a few places by now. So I raised
       the default C++ standard to C++14. This is the default in ATLAS builds since
       a while, I only saw this as an issue when building Gaudi "on its own" with a
       very minimal configuration command.
         * While the code advertises that it still has support for ROOT 5, it's not
       able to build against it since a wile. Since the updates I put in for TLS
       variables on macOS. (The macros used there are ROOT 6 only.) And this update
       makes things even worse. As the code now relies on not providing the
       definition of some classes to the dictionary generator in GaudiPython that
       are not available. (Because AIDA or XercesC is missing.) While ROOT 6 handles
       this with just a build warning, ROOT 5's genreflex treats this with an ERROR
       message. That I was unable to get rid of.
        So, extended testing is clearly necessary, the configuration code could
       definitely be fine tuned as I probably turned off the build of more source
       files than absolutely necessary, but I think we should move ahead with such a
       configuration organisation.

    ! 2016-10-27 - Gerhard Raven, Marco Clemencic (commit b111898)

     - modernization of Property

       This is a major rewrite of the system of `Property` classes. Started as  the
       implementation of GAUDI-1214, it continued as a review of
       `IProperty` and `PropertyMgr`, to end up in a complete rewrite
       (and optimization) of `PropertyWithValue`.

       * Fixes GAUDI-1214
        - added missing `declareProperty` signature
        - added `PropertyHolder` (an updated `PropertyMgr`)
        - adapted all properties in Gaudi
       * improved use of `PropertyHolder`
        - use inheritance instead of composition
        - removed ~200 (duplicated) lines of code in GaudiKernel
       * optimization of Property (fixes GAUDI-1229)
        - use templates and automatic code generation to handle efficiently
          both value and reference properties
          - avoid creation of values on the heap (see GAUDI-1229)
          - removed the *owned* boolean flag
          - improved usability of properties (e.g. begin/end wrappers for
            C++11 loops, increment/decrement operators...)
          - deprecated use of C arrays as properties
        - merged features of `PropertyWithVerifier`, `SimpleProperty` and
          `SimplePropertyRef` into `PropertyWithValue`
        - deduplication of name and doc strings via

       [`boost::string_ref`](http://www.boost.org/doc/libs/1_61_0/libs/utility/doc/html/string_ref.html)

          and a static storage  (see GAUDI-1229)
       * Fixes GAUDI-1205
       * add deprecation warnings in service accessors of `Algorithm` (@graven)
       * renamed `Property` base class to `Gaudi::Details::PropertyBase` and
       `PropertyWithValue` to `Gaudi::Property`
        - added backward compatibility type aliases (but not compatible with
          forward declarations of `class Property`, which should be replaced
          by `#include "GaudiKernel/PropertyFwd.h"`)
       * added macro `GAUDI_PROPERTY_v2` to allow easy implementation of
        backward compatible changes in derived projects (e.g. when user code
        relied on `DoubleProperty` having a verifier)
       * Fixes GAUDI-1268
        The changes are as backward compatible as much as possible (except if you
       explicitly inherit from `SimpleProperty`, or you forward declared
       `class Property`, which now are typedefs), but must be validated in the
       experiment frameworks.

    ============================= GaudiPython v14r0 ==============================

    ! 2015-09-25 - commit 35dd00c

     - Merge branch 'dev-smartif-use' into 'master'

       Provide (and use) C++11 smart pointer 'look and feel' for SmartIF

       The aim of this branch is to confine, for everything that inherits from
       IInterface, the calls to addRef(), release() and queryInterface() to the
       SmartIF implementation. Exceptions are a few places where interfaces
       (currently) return bare pointers (instead of SmartIF...) and where one thus
       has to addRef() explicitly to avoid returning a dangling pointer. This can be
       avoided by changing the relevant interface to return a SmartIF instead of a
       bare pointer.

       In addition, make SmartIF 'look and feel' like a smart pointer.

       - use explict bool conversion instead of .isValid()
       - add SmartIF::as<IFace>(), to return a SmartIF<IFace> to an alternate
          interface -- which (together with move) encourages the use of auto
       - add ISvcLocator::as<IFace>(), to return a SmartIF<IFace> to the current
       ISvcLocator.
       - add ServiceManager::service<IFace>() which return SmartIF<IFace> which
       encourages
          the use of auto

       And add a few other C++11 modernizations (eg. prefer STL over raw loop)

       Fixes GAUDI-1094

     - Normalization of white-spaces in Python files.
       (using http://svn.python.org/projects/python/tags/r254/Tools/scripts/reindent.py)

    ! 2009-10-12 - Vanya Belyaev
     - Patch #3328: iDataSvc.findObject
       - GauidPython::Helper
         1. add method findobject (wrapper for IDataProviderSvc::findObject)
         to get object from Transient store without trying to load or
         use on-demand actions
         2. add method getobject with allows total control over access
         object in Transient Store : retrieve versus find, and allows
         temporarily disable on-demand actions. Thus one can allow loading
         the object from tape, but switch off on-demand actions
       - GaudiPyton/Bindings.py
         1. iDataSvc      : add methods findObject and getObject
         2. PropertyEntry : for properties with missing dictionaries
            (essentially,  missing "value" attribute) use the
            "toString"-result as self._value.
     - Patch #2978: GaudiKernel/StringKey.h
       Added dictionary and support in Pythonizations.py and Bindings.py

    ! 2009-10-09 - Eoin Smith
     - Patch #3297: Support for GaudiPython Parallel in gaudirun.py
       Added scatter-gather parallel model to python/GaudiPython/Parallel.py
       Consists of 1reader-Nworkers-1writer, for event-parallel execution using
       Python processing package, forking and unix queues/pipes.
       Execute gaudirun.py with flag --parallel=N (N>=1)

       Two new methods in python/GaudiPython/Bindings.py
       iDataSvc().getList() returns a list of all paths present on a local
       file.  For example, all local TES paths for one event.  Links to external
       files are ignored (by checking the address() property)
       iDataSvc().getHistoNames() returns a list of all paths in a Transient Store
       without checking File ID

       Modified src/Lib/TESSerializer.cpp : method dumpBuffer now takes a
       TBufferFile pointer as an argument.  Previously, dumpBuffer was creating
       its own new TBufferFiles for each call, which led to an error where new
       calls reset the buffer of previous calls. loadBuffer also modified to
       use data directly from TBufferFile to rebuild Transient Event Store
       (instead of intermediate buffer)

       Modified GaudiPython/TESSerializer.h to reflect these changes.

    ! 2009-10-09 - Marco Clemencic
     - Disabled the dictionary for GaudiAlg::HistoBinEdges (a typedef to vector<double>)
       because it triggers the presence of vector<double> in the rootmap file, which
       produces a warning in ROOT > 5.24.00a.

    ! 2009-10-08 - Vanya Belyaev
     - Patch #3311: Add ASCII dump for 1D-profile histograms
       Extension of patch #3261 to 1D-profile histograms
     - Patch #3223: Add some more "Extended" property types to Gaudi
       Fix to use the new properties.

    ! 2009-10-07 - Vanya Belyaev
     - Patch #3261: Utility for ASCII dump of 1D-histograms
       Added the bindings for function Gaudi::Utils::Histo::histoDump.

    ! 2009-10-02 - Vanya Belyaev
     - Patch #3157: Remove redundant duplicated  maps from GaudiHistos/GaudiTuples
       Adapted HistoDecorator to the changes in GaudiHistos.

    ! 2009-10-02 - Marco Clemencic
     - Fixed bug #56358: Algorithms crashing in finalize are finalized a second time
       - Added a protection to avoid that AppMgr.exit() can be called twice.
       - Removed the "atexit" handler and replaced it with a specialized destructor
         for AppMgr. Note that it may not be called in case of circular dependencies
         between Python objects, in which case AppMgr.exit() have to be called
         explicitely.

    ================ GaudiPython v10r4 ====================================
    ! 2009-07-30 - Marco Clemencic
     - Fixed some doxygen warnings.

    ! 2009-07-23 - Pere Mato
     - Patch #3152: Adapting GaudiPython to new null pointer semantic of ROOT 5.22.00c
       The new patched version of ROOT 5.22.00c returns 'typed null pointers' instead
       of None. Form the point of view of python this is different than None and
       therefore tries to call _repr_ when ever the object is evaluated interactively.
       For this reason we need to protect the generic implementation of __repr__ for
       DataObject and ContainedObject.
       At the same time tried to load the necessary ostream and stringstream from
       the beginning avoiding some spurious problems (fixes bug #28426).

    ! 2009-07-22 - Vanya Belyaev
     - Fixed bug #53514: The local symbol "HID" is not defined.

    ! 2009-07-20 - Marco Clemencic
     - Added '-no_static' to the declaration of the libraries (implemented since CMT
       v1r20p20081118).

    ! 2009-07-17 - Juan Palacios
     - Patch #3091: Class for easy saving of GaudiPython histograms
       Add HistoFile, a class for easy writing of ROOT and AIDA histograms
       to a file.

    ! 2009-07-16 - Vanya Belyaev
     - Patch #3134:
       - Some polishing of GaudiPython.GaudiAlgs module and related modules
       - More handles for interactive algorithm inspection (GaudiPython)
       Detailed description in GaudiAlg/doc/patch_3134.html

    ================ GaudiPython v10r3 ====================================

    ! 2009-04-08 - Pere Mato
     - Patch #2958: New runSelectedEvents() method in GaudiPython.AppMgr
       Added new method runSelectedEvents(self, pfn, events) on AppMgr class
       This method allows to execute the event loop on a specific event(s) for a given input (POOL)
       file (physical file name).
       It requires new version of GaudiUtils including the dictionary for IFileCatalog interface

    ! 2009-04-07 - Marco Clemencic

       for interactive histogram manipulation.

    ! 2009-03-13 - Marco Clemencic
     - Task #9061: Introduction of component managers
       - Adapted to use the changes in the ISvcLocator, ISvcManager and IAlgManager
         interfaces.

    ! 2009-02-19 - Marco Clemencic

     - Symbol visibility
       - Decorated all the classes and functions that needs to be exported (see
         GaudiKernel release.notes).
       - Added a hack to force the export of the symbols of AIDA interfaces to allow
         the dynamic_cast (see GaudiSvc release.notes).

    ! 2009-01-22 - Marco Clemencic
     - Adapted to the new IInterface functionalities (see GaudiKernel release.notes)
     - Replaced the usage of TimePoint with Gaudi::Time.

    ================ GaudiPython v9r4 ====================================
    ! 2008-12-16 - Marco Clemencic
     - Fixed bug #45392: gaudrun.py returns status code 0 even if the application

     - Fixed the dependency for the serialization functions.

    ! 2008-10-31 - Vanya Belyaev
     - Fixed a typo in Bindings.iDataSvc (it was "self.dict" instead of
       "self.__dict__").

    ! 2008-10-30 - Marco Clemencic
     - Modified AppMgr to ensure that GaudiKernel.Configurable.applyConfigurableUsers()
       is called before configuring the application (needed for GaudiPython scripts).

    ! 2008-10-29 - Charles Leggett

                    representation
       "Draw" and "plot" member functions are added to the AIDA histogram interfaces
       at import time. They are implemented forwarding the call to the internal
       ROOT instances.

     - requirements: tweak test_GPyTest_rootmap macro to work with GAUDI_ATLAS tag

    ! 2008-06-25 - Marco Clemencic
     - Fixed GaudiPython/Bindings.py to work with the HEAD version of ROOT too.

    ================ GaudiPython v9r1 ====================================

    ! 2008-04-24 - Stefan Roiser
     - Fixed compilation problem on MacOS Leopard.

    ================ GaudiPython v8r19 ====================================
    ! 2008-02-27 - Marco Clemencic
     - Hack to avoid a conflict in the way Configurables are used in Athena and
       Gaudi.  In GaudiPython they are used in the AppMgr constructor, while in
       Athena they are used in a different moment (and not even all of them are
       needed).
       The conflict is resolved by using a function to return the needed
       configurables, implemented to return the keys of allConfigurables for Gaudi
       and and empty list for Athena.

    ! 2008-01-29 - Marco Clemencic
     - Fixed Bug #32854. (MessageSvc options ignored in Python)
       Modified the constructor of GaudiPython.AppMgr to set explicitly the
       properties of MessageSvc just after the ApplicationMgr configuration.
       (It does not work for MessageSvc.loggedStreams because the update handler is
       missing)
     - Lock the configurables setting Configurable.__configurationLocked (if it
       exists) after the configuration of AppMgr, to avoid that users try to change
       the configuration when it is too late.

    ================ GaudiPython v8r18 ====================================
    ! 2008-01-18 - Marco Clemencic
     - Fixed a problem with python options: the ApplicationMgr output level was not
       set.

    ! 2008-01-17 - Pere Mato
     - Fixed macro for  test_GPyTestDict needed after change in the reflex test dictionary pattern

    ! 2008-01-16 - Wim Lavrijsen
     - Fixed a bug in Pythonization._loadDict. Missing "import sys".

    ! 2008-01-15 - Wim Lavrijsen
     - AthenaCommon does not have Configurable.PropertyReference and this must be
       considered in GaudiPython.Bindings.

    ! 2008-01-11 - Marco Clemencic
     - Implemented correct handling of late-bound options.

    ! 2007-12-18 - Marco Clemencic
     - Fixed a compilation bug with Python 2.5 (backward compatible).

    ! 2007-11-30 - Marco Clemencic
     - Fix for bug #31677.
       Move GaudiHandles.py from GaudiPython to GaudiKernel. Added a fake module for
       backward compatibility.

    ! 2007-11-30 - Pere Mato
     - Fix for bug #31819: Reduce GaudiPython dictionaries to strict minimum.
       Removed common STL classes (9 in total) from the rootmap file using
       the attribute rootmap="false" in the selection file.

    ! 2007-11-28 - Paolo Calafiura & Sebastien Binet
     - patch #1550.
       Fix to compile with Python 2.5 (backward compatible).

     - Remove the dependency of GaudiPython/__init__.py from Gaudi.Configuration.
     - Use GaudiKernel.Proxy to get the correct version of Configurable.

    ! 2007-10-29 - Pere Mato
     - Changed the structure of the package.
       decribed at:  https://twiki.cern.ch/twiki/bin/viewfile/LHCb/GaudiPython?rev=1;filename=GaudiPython_20071017.pdf

    ! 2007-10-24 - Marco Clemencic
     - Fixed a problem in the generation of rootmap files for GaudiPython test
       dictionaries (target "tests").

       - Improve doxygen comments.
       - Add dictionaries for ITupleTool and IHistoTool.
       - New module TupleUtils.py: allow manipulation of tuples from
         outside algorithms or tools.
     - patch 1263.
       - Allow "smart and friendly" manipulation of AIDA::IProfile[1D,2D]
         objects from Python.
       - Added few dictionaries and few new helpers.
       - Improvements in iProperty: raise AttributeError in __getattr__
         and __setattr__ if the property does not exist (instead of the
         internal C++ exception).
       - Improved the documentation strings of few functions.
       - Improvements to GaudiAlgo, HistoAlgo and TupleAlgo as for
         iProperty.
       - Added module HistoUtils containing "script-friendly" functions
         to manipulate histograms.

    ! 2007-07-16 - Hubert Degaudenzi
     - remove the explicit Dlls options from gaudimodule.py (not needed
       any more)

    ! 2007-04-05 - Martin Woudstra
     - Patch #1103. The attached 2 patches (one for GaudiPython and one
       for GaudiKernel) contain the changes needed to support
       ToolHandleArray's (a 'vector' of ToolHandles). This is a new
       feature, and is already in use in ATLAS. In addition to the
       ToolHandleArray and its associated base classes, there is the
       GaudiHandleArrayProperty, and an update to genconf to support it

    ! 2007-04-04 - Pere Mato

      Patch #1106. possible solution for Savannah bug #25109 and patch
      #1024 (wrongly closed)
     - dict/selection_kernel.xml
        add the dictionary for GaudiHandleProperty class
     - python/gaudimodule.xml
        a) PropertyEntry
          1) reimplement constructor in a way to
          set the data member _value to be valid python type for
          LHCbproperties and to keep the previousl behaviour for ATLAS
          GaudiHandleProperty
          2) add local data mamber PropertyEntry._property and
           function PropertyEntry.property() to access to the original
           property. (Useful to perform the second try, if the
           failure occurs in constructor)
        b) minor modification of iProperty.__getattr__
           to avoid the sad printout of numerous warning messages:
         "Warning in <TClass::TClass>: no dictionary for class
         vector<pair<double,double> > is available "..

    ! 2005-08-17 - Vanya BELYAEV
     - modifications for updated GaudiAlg to incorporate
      very attractive feature: "universal" (numeric or
      alphanumeric) histogram/ntuple identifier, introduced
      by Chris into GaudiAlg

      Now major methods of Python's HistoAlgo and Tuple Algo
      from now could accept both numerical identifier,
      string identifier or "universal identifier:

      e.g. for N-Tuples :

        t1 = self.nTuple( 1             , 'My first  NTuple'     )
        t1 = self.nTuple( 'BLAH'        , 'My second NTuple'     )
        t1 = self.nTuple( TID ( 16 )    , 'My third NTuple # 16' )
        t1 = self.nTuple( TID ( 'XXX' ) , 'My fourth NTuple '    )
        t1 = self.nTuple( 'SUBDIR/AA'   , 'My fifth NTuple in subdirectory')

      similar for (1D,2D,3D)-histograms:

        self.plot1D( mass ,          ' This is 1st histogram ' , 1 , 10 )
        self.plot1D( mass , 2      , ' This is 2nd histogram ' , 1 , 10 )
        self.plot1D( mass , 'MASS' , ' This is 3rd histogram ' , 1 , 10 )
        self.plot1D( mass , 'subdir/MASS' , ' This is 4th histogram ' , 1 , 10 )
        self.plot1D( mass , HID( 44)  , ' This is 5th histogram ' , 1 , 10 )
        self.plot1D( mass , HID('M')  , ' This is 6th histogram ' , 1 , 10 )

      for profiles, one need to use HID explicitly:

         self.profile1D ( x , y ,                  ' title1 ' , 0 , 10 )
         self.profile1D ( x , y , HID(25)        , ' title2 ' , 0 , 10 )
         self.profile1D ( x , y , HID('x%y')     , ' title3 ' , 0 , 10 )
         self.profile1D ( x , y , HID('dir/x%y') , ' title4 ' , 0 , 10 )

    ! 2005-08-07 - Vanya BELYAEV
     - few major (*BACKWARD COMPATIBLE*) modifications to simplify
       the interactive analysis. Namely the useful base classes from
       GaudiAlg package are imported into the Python.
       Also major reshuffling of existing codes is performed to allow
       the reuse of code outside the GaudiPython package (e.g.
       in the context of Bender or Panoramix projects) without
       multiple explicit code duplicated (as it is now... :-((( )

       From now package builds also linker library GaudiPythonLib
       The dictionary is renamed to GaudiPythonDict (to avoid the
       masking of GaudiKernelDict built by GaudiKernel package)
       As a result the package now builds 3 library:
         1) component library  GaudiPython
         2) linker library     GaudiPythonLib
         3) dictionary library GaudiPythonDict

       New module GaudiAlgs.py is added into $GAUDIPYTHONROOT/python
       directory. This module contains essentially the base classes
       GaudiAlgo, HistoAlgo and TupleAlgo and the extensive documentations

       GaudiPython/kernel.h and GaudiPython/selection_kernel.xml
       now contains *ALL* abstract interfaces from GaudiKernel and
       GaudiAlgs packages

       $GAUDIPYTHON/python/gaudimodule.py file gets "atexit" function,
       making the exit statement optional (it is VERY convenient
       for scripts which is supposed to work both interactively and
       "as batch")

         New files:
         ==========
         $GAUDIPYTHONROOT/python/GaudiAlgs.py
         $GAUDIPYTHONROOT/GaudiPython/GaudiPython.h

           rb  = evt['DAQ/RawBuffer']
           raw = gaudimodule.toIntArray( rb.buffer(), rb.currentSize() )
           for i in raw :  print i
