    ! 2017-02-08 - Charles Leggett (commit 09859bd)

     - add sysExecute(EventContext) and extract errorCount from Algorithm base class

       We need to extract the `m_errorCount` variable from the Algorithm base class,
        as it's not important on a per-instance basis, but rather on a job level.
       This is moved to the AlgExecStateSvc.
        This merge request also adds an explicit `IAlgorithm::sysExecute(const
       EventContext&)`, which should become the standard entry point to
       `Algorithm::execute`. This sets the local m_event_context variable, so
       derived classes can get quick access to the current context instead of going
       through the slower thead local `Gaudi::Hive::currentContext()`.
        Note that `IAlgorithm::sysExecute()` has been removed, to avoid "overloaded
       virtual" compiler errors, and should be replaced in all clients with
       `IAlgorithm::sysExecute(EventContext)`, or if the context is not immediately
       available, with `IAlgorithm::sysExecute(Gaudi::Hive::currentContext())`.
        All this is being done in preparation to re-introduce the ReEntrantAlgorithm
       class from merge !177 (see also !274)
        See merge request !273

    ! 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.

    ! 2016-10-24 - Marco Clemencic (commit a8d6605)

     - hidden/fixed "missing override" warnings exposed after !192

       - warnings from external headers are hidden declaring the include directories
       as `-system`
       - warnings from a couple of new files have been fixed
       - warnings in `HistogramSvc` are hidden because unavoidable (see f83c3d8e)
       - warnings related to CLHEP-136 have been hidden with a special trick (see
       0a238135)

    ! 2016-10-19 - Charles Leggett (commit 958570b)

     - Algorithm Execution State Service

       Introduction of AlgExecStateSvc
        All event state information removed from Algorithm base class
       (m_filterPassed, m_isExecuted) as it will cause difficulties with re-entrant
       Algorithms.
        event success/fail flag removed from EventContext
        These flags are moved to be under control of a new service, the
       AlgExecStateSvc, which keeps track of the execution state of all Algorithms,
       and the Event as a whole.
        Algorithm status kept in a new class ```AlgExecState``` which has
       ```
           bool m_filterPassed  {true};
           bool m_isExecuted    {false};
           StatusCode m_execStatus  {StatusCode::FAILURE};
       ```
        AlgExecStateSvc holds an AlgExecState for each Algorithm in each Event
       Slot, as well as an overall ```EventStatus``` for each EventSlot, which can
       be one of

       ```
         Invalid = 0,
         Success = 1,
         AlgFail = 2,
         AlgStall = 3,
         Other = 4
       ```
        Algorithms add themselves to the AlgExecStateSvc upon initialization, but
       the Service's initialization of  the data structures is deferred until the
       first time ```AlgExecStateSvc::reset()``` is called, at which point it's
       probably safe to figure out if there's a WhiteBoard, and the number of slots
       to allocate.
        The EventLoopMgr should call ```AlgExecStateSvc::reset()``` at the start of
       each event. If it's a concurrent EventLoopMgr, it should be
       ```AlgExecStateSvc::reset(EventContext)```, after the EventContext object
       has been updated to reflect the new event.
        Also added an EventContext object to the MinimalEventLoopMgr, so that
       serial/concurrent behaviour is similar.
        Concurrent queries to the AlgExecStateSvc must contain the EventContext, so
       the correct EventSlot can be determined. Serial access is via methods that
       don't have the EventContext as a parameter. For access from Algorithm base
       class (eg from setFilterPassed, isExecuted, etc), if the EventContext ptr
       (m_event_context) in the Algorithm is null, we assume we're running
       serially.

     - Adding concurrent incident support and example utilization.

       `GaudiExamples/options/AsyncIncidents.py` demonstrates example utilization of
       asynchronous incident mechanism.

        See merge request !181

    ! 2016-05-31 - Charles Leggett (commit d79ce22)

     - use std::list for ListenerList in IncidentSvc

       Using std::list instead of std::vector allows the possibility of listeners
       being added during the handling of an incident, which cannot be forbidden
       because a handler may trigger instantiation of a component that wants to be
       registered.

    ! 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)

           app = ApplicationMgr()
           app.AlgTypeAliases['MyAlg'] = 'MyNewAlg'

       instruct the AlgorithmManager to create instances of MyNewAlg whenever it is
       requested to create a MyAlg.
       The aliasing can be bypassed by prefixing the string 'unalias:' to the class
       name.

     - Improvements to DataOnDemandSvc:
       - do not load the ToolSvc if not needed
       - ensure that the tools are not released if the ToolSvc is already finalized

    ! 2012-01-16 - Marco Clemencic
     - Modified DataOnDemandSvc to accept tools to map paths to node types
       (IDODNodeMapper) and to algorithms (IDODAlgMapper).
       Note: the mapping is cached in the usual internal structures so the
             implementation of the tools must always return the same answer for the
             same path.
     - Added a basic IDODNodeMapper and IDODAlgMapper (DODBasicMapper) implementing
       the minimal DataOnDemandSvc static mapping.
