Wed Mar 26 14:32:40 2003  Balachandran Natarajan  <bala@isis-server.isis.vanderbilt.edu>

	* tao/ORB_Core.h:
	* tao/ORB_Core.cpp: Removed methods initialize_collocated_object
	  () and create_collocated_object (). Added a new method
	  is_collocation_enabled () which abstracts the common code in the
	  above two methods. 

	* tao/Object.cpp: Cosmetic fixes!

	* tao/PortableServer/Object_Adapter.cpp:
	* tao/PortableServer/Object_Adapter.h: Added a new method
	  get_collocated_servant (), which houses the common code in
	  create_collocated_object () and initialize_collocated_object
	  (). 
	
Tue Mar 25 18:16:05 2003  Balachandran Natarajan  <bala@isis-server.isis.vanderbilt.edu>

	* tao/Profile.cpp: Missed a definition of a constructor during the
	  merge.

Tue Mar 25 17:14:22 2003  Balachandran Natarajan  <bala@isis-server.isis.vanderbilt.edu>

	* tao/Domain/DomainS.cpp: Fixed compile errors.

Tue Mar 25 16:11:39 2003  Balachandran Natarajan  <bala@isis-server.isis.vanderbilt.edu>

	Merged with main trunk!

Mon Mar 24 13:57:09 2003  Balachandran Natarajan  <bala@isis-server.isis.vanderbilt.edu>

	* tao/Object.h:
	* tao/Object.cpp (_is_local): 
	* tao/Object.i: Cosmetic fixes like improved documentation, making
	  most of the member variables private instead of protected
	  etc. Changed the member initializations to suit the above
	  cosmetic fix. 
	
	* tao/PortableServer/Collocated_Object.cpp: Cosmetic fixes.

Mon Mar 24 09:16:11 2003  Balachandran Natarajan  <bala@isis-server.isis.vanderbilt.edu>

	* tao/Object.cpp: The return value from the call to
	  initialize_object () is voided since not much can be done at
	  that point if failures occur. We will do error checking later to
	  throw the right exceptions. 

Fri Mar 21 17:07:11 2003  Balachandran Natarajan  <bala@isis-server.isis.vanderbilt.edu>

	* tao/Adapter.h:
	* tao/Adapter.cpp: Added a method initialize_collocated_object ()
	  in the TAO_Adapter_Factory and TAO_Adapter.

	* tao/ORB_Core.pp: Implemented the initialize_collocated_object ()
	  which basically calls the
	  TAO_Adapter_Registry::initialize_collocated_object (). 

	* tao/PortableServer/Object_Adapter.cpp:
	* tao/PortableServer/Object_Adapter.h: Added a new method
	  initialize_collocated_object (). The implementation is pretty
	  much similar to the create_collocated_object (), but instead of
	  creating a new object, initializes an existing object. 

	* tao/Object.h: 
	* tao/Object.cpp:
	* tao/Object.i:

	  Added the following methods 
	  
	  - set_collocated_servant () which helps to initialize the
	    CORBA::Object with TAO_Abstract_ServantBase

	  - Accessors for orb_core () and IOP::IOR

	  Added initialization of collocated objects in
	  tao_initialize_object (). 

	  The above checkin has lots of duplicated code. Need to refactor
	  them in the next round. 
	  
Fri Mar 21 16:37:12 2003  Balachandran Natarajan  <bala@isis-server.isis.vanderbilt.edu>

	* TAO_IDL/be/be_interface.cpp: Added a new argument to the
	  constructor of stub objects. This change is made to make sure
	  that stub objects have constructors similar to the
	  CORBA::Object. 

	* TAO_IDL/be/be_visitor_interface/interface_ch.cpp: Added a new
	  constructor as required by the latest changes to the
	  CORBA::Object. 
	
	* TAO_IDL/be/be_visitor_interface/interface_ci.cpp: Definition of
	  the above constructor. 
	
	* TAO_IDL/be/be_visitor_interface/interface_cs.cpp: In
	  _unchecked_narrow () we create a interface pointer object if the
	  IOR is lazily evaluated by giving it the IOP::IOR and the
	  ORB_Core. 
	
	* TAO_IDL/be/be_visitor_operation/operation_cs.cpp: In the
	  code generation for operation, initialize the object completely
	  ie. evaluate the IOR completely and setup collocation if they
	  have not been setup before (which is possible if the IOR's are
	  evaluated lazily) proceeding with the operation. 
	
	* TAO_IDL/be/be_visitor_component/component_ch.cpp:
	* TAO_IDL/be/be_visitor_component/component_ci.cpp:
	* TAO_IDL/be/be_visitor_component/component_cs.cpp: Retrofit the
	  above changes for components too.  

Wed Mar 19 16:05:11 2003  Balachandran Natarajan  <bala@isis-server.isis.vanderbilt.edu>

	* TAO_IDL/be/be_visitor_component/component_cs.cpp:Added a check
	  for is_evaluated () before creating a new CORBA::Object () in
	  _unchecked_narrow (). If the call is_evaluated fails, we just
	  reinterpret cat the CORBA::Object to the right type of object.

Wed Mar 19 15:35:16 2003  Balachandran Natarajan  <bala@isis-server.isis.vanderbilt.edu>

	* TAO_IDL/be/be_visitor_interface/interface_cs.cpp: Added a check
	  for is_evaluated () along with _is_local () before creating a
	  new CORBA::Object () in _unchecked_narrow ().
	
Wed Mar 19 14:30:43 2003  Balachandran Natarajan  <bala@isis-server.isis.vanderbilt.edu>

	* tao/Connector_Registry.cpp: Removed preconnect () completely
	  from the code.

	* tao/ORB_Core.cpp: Implemented the initialize_object () for
	  non-local and non-collocated cases. 

	* tao/Object.h:
	* tao/Object.cpp (Object): 
	* tao/Object.i: Made the following changes

	  - Changed the constructor that took a const IOP::IOR_var to take
	    a pointer to IOP::IOR. The pointer would be owned by
	    CORBA::Object class and released at the end of its
	    lifetime. It may be possible for us to release the memory
	    owned by IOR_var if needed after the complete evaluation is
	    done. At this point of time it is future work. 

	  - Added a new method is_evaluated () which returns the status of
	    the evaluation done on the IOR.

	  - Added a non-const version of _stubobj ().

	  - In the main constructor we set the ORB_Core if it is null
	    before calling the resource factory to create the refcount
	    lock. 

	  - In the method is_nil_i () we now use the ORB_Core to access
	    new definitions instead of going through the stub object. This
	    would prevent accidental evaluation of IOR while calling
	    is_nil () from the stubs or skeletons. 

	  - Completed implementation of tao_object_initialize () for
	    non-local and non-collocated objects. 

	  With this checkin the Hello test and IORsize test work fine. 

	
Fri Mar  7 13:29:43 2003  Balachandran Natarajan  <bala@isis-server.isis.vanderbilt.edu>

	* tao/Object.cpp:
	* tao/IOP_CodecC.h:
	* tao/IOP_IORC.h:
	* tao/Makefile.tao:
	* tao/IOPC.h: Fixed compile errors with g++.

Fri Mar 07 09:49:35 2003  Balachandran Natarajan  <bala@isis-server.isis.vanderbilt.edu>

	* TAO_IDL/be/be_codegen.cpp:
	* TAO_IDL/be_visitor_operation/thru_poa_proxy_impl_ss.cpp: Changed
	  the generated code to call object_key () on the stub object
	  within the CORBA::Object instead of calling _object_key (). 

Mon Mar 03 14:07:10 2003  Balachandran Natarajan  <bala@isis-server.isis.vanderbilt.edu>

	This is just a temporary checkin to test it on another box.
	
	* tao/IOP_Codec.pidl:
	* tao/IOP_IOR.pidl: New files. 
	
	* tao/IOP.pidl: Split the IOP.pidl into two pidl files. 

	* tao/IOPC.cpp
	* tao/IOPC.h:
	* tao/IOPC.i: New generated files. 
	
	* tao/Buffering_Constraint_Policy.cpp: Initialized the base
	  classes properly. 
	
	* tao/ORB_Core.cpp:
	* tao/ORB_Core.h: Incomplete changes to initialize the CORBA
	  object. 

	* tao/Object.cpp:
	* tao/Object.h:
	* tao/Object.i: Added partial support for delayed creation of
	  CORBA::Objects. This included adding a new static method
	  tao_object_initialize (). The extraction operator will extract
	  out to a IOP::IOR if lazy evaluation is used. Removing
	  _object_key () since it serves very less purpose in this object
	  but for just accessing the Stub to get the key. The lazy
	  evaulation would be happy with this scenario!
	
	* tao/Resource_Factory.cpp:
	* tao/Resource_Factory.h: Added the follwoing virtual methods
	  - create_corba_object_lock (), which creates a SYNCH_MUTEX or a
	    NULL_MUTEX as the case may be for CORBA::Object. 
	  - resource_usage_strategy (), a strategy for advising whether
	    the resources are used actively or lazily within the ORB. This
	    strategy is not useful through out the ORB right away. There
	    is atleast one place where this might be used now and it is in
	    CORBA::Object. The >> of a CORBA::Object from a TAO_InputCDR
	    will use this strategy.

	* tao/default_resource.cpp:
	* tao/default_resource.h: Concrete implementations for the above
	  pure virtual methods within the default factory.
	
	* tao/TAO.dsp: Added new files in to the project files. 
	
	* tao/PortableServer/Collocated_Object.cpp:
	* tao/PortableServer/ImR_LocatorS.cpp:
	* tao/PortableServer/ImplRepoS.cpp:
	* tao/PortableServer/PolicyS.cpp:
	* tao/PortableServer/ThruPOA_Object_Proxy_Impl.cpp: Use the stub
	  object on the CORBA::Object to access the ObjectKey instead of
	  calling _object_key (). The  method _object_key () is going to
	  be removed.

Sat Feb 22 22:30:25 2003  Balachandran Natarajan  <bala@isis-server.isis.vanderbilt.edu>

	* Merged with the main trunk.

Thu Feb 20 12:48:16 2003  Balachandran Natarajan  <bala@isis-server.isis.vanderbilt.edu>

	* ace/Connector.cpp: Added a const to regulate the size of the map
	  that is being used inside this class. A size of 1024 seems too
	  excessive for runtime memory.

Thu Feb 20 12:29:17 2003  Balachandran Natarajan  <bala@isis-server.isis.vanderbilt.edu>

	* tao/Profile.h:
	* tao/Profile.cpp:
	* tao/Profile.i: Moved the ObjectKey from the inherited classes
	  to the base class. Added a new protected constructor which can
	  be used by the inherited classes to initialize the ObjectKey
	  properly. Also added a new method set_tagged_components () which
	  is a helper method useful for creating Tagged_Components of an
	  IOR from a CDR stream. Uninlined the constructor, destructor and
	  the methods for refcounted memory management.

	* tao/IIOP_Profile.h:
	* tao/IIOP_Profile.cpp:
	* tao/Strategies/DIOP_Profile.h:
	* tao/Strategies/DIOP_Profile.cpp:
	* tao/Strategies/UIOP_Profile.h:
	* tao/Strategies/UIOP_Profile.cpp:
	* tao/Strategies/SHMIOP_Profile.h:
	* tao/Strategies/SHMIOP_Profile.cpp: Removed the ObjectKey from
	  the following classes since it has now been moved to the base
	  class. 
	  
	  Used the protected constructor in the base class while base
	  member initializations.  

	  Call the set_tagged_componets () to place a list of
	  IIOPEndpoints in the Tagged_Components contained in the profile.
	
Thu Feb 20 12:10:13 2003  Balachandran Natarajan  <bala@isis-server.isis.vanderbilt.edu>

	* tao/Tagged_Components.h:
	* tao/Tagged_Components.cpp:
	* tao/Tagged_Components.i (TAO_Tagged_Components): Reverted the
	  change "Wed Feb 12 15:40:46 2003  Balachandran Natarajan
	  <bala@isis-server.isis.vanderbilt.edu>" since it was counter
	  productive. 

	* tao/ClientRequestInfo_i.cpp: Reverted the changes made to
	  accomodatethe above change.

Thu Feb 13 17:53:44 2003  Balachandran Natarajan  <bala@isis-server.isis.vanderbilt.edu>

	* tao/IIOP_Endpoint.h (TAO_IIOP_Endpoint): 
	* tao/IIOP_Profile.h:
	* tao/Strategies/DIOP_Endpoint.h:
	* tao/Strategies/SHMIOP_Endpoint.h: Cosmetic changes like removing
	  ORB.h  inclusion etc.

Wed Feb 12 18:15:24 2003  Balachandran Natarajan  <bala@isis-server.isis.vanderbilt.edu>

	* Merged in changes from the main trunk.

Wed Feb 12 15:40:46 2003  Balachandran Natarajan  <bala@isis-server.isis.vanderbilt.edu>

	* tao/Tagged_Components.h:
	* tao/Tagged_Components.cpp:
	* tao/Tagged_Components.i (TAO_Tagged_Components): Create
	  IOP::MultipleComponentProfile lazily, instead of creating
	  actively on the stack and increase the runtime footprint. If we
	  do this we only pay when TAO gets something that TAO doesnt
	  understand. This changed forced us to change the signature of
	  the components (). Instead of returning a reference we now
	  return a pointer to the underlying
	  IOP::MultipleComponentProfile. 

Thu Feb  6 17:51:06 2003  Balachandran Natarajan  <bala@isis-server.isis.vanderbilt.edu>

	* tao/Tagged_Components.cpp: Removed some vague print statements. 
	* tao/Strategies/SHMIOP_Connector.cpp: Fixed some debug
	  statements. 

Thu Feb  6 16:37:32 2003  Balachandran Natarajan  <bala@isis-server.isis.vanderbilt.edu>

	* tao/Stub.cpp (ior_info_): 
	* tao/Invocation.cpp:
	* tao/ClientRequestInfo_i.cpp: Added error checks to the last
	  checkins. 

Sun Jan 26 23:50:17 2003  Balachandran Natarajan  <bala@isis-server.isis.vanderbilt.edu>

	* tao/Profile.cpp:
	* tao/Profile.h:
 	* tao/Profile.i: Added a new method create_tagged_profile
	  (). Infact, this method existed in the derived classes returning
	  a reference to the underlying IOP::TaggedProfile. Since the
	  method existed in all the derived classes and was doing similar
	  things it has now been moved to the base class with a slight
	  signature change. This now returns a pointer to the underlying
	  IOP:TaggedProfile. The signatuer change has been needed because
	  of the change mentioned below.

	  We will henceforth hold a pointer to the IOP::TaggedProfile
	  instead of an instance in the Profile classes. We will create an
	  instance when needed, (heard of lazy evaluation?). This change
	  is forced on us due to the runtime memory consumed by
	  IOR's. Holding a pointer instead of the actual object instance
	  gets us approximately 24 bytes per IOR on Linux on a 32 bit
	  processor. 

	* tao/IIOP_Profile.h:
	* tao/IIOP_Profile.cpp: 
	* tao/Strategies/UIOP_Profile.cpp:
	* tao/Strategies/UIOP_Profile.h:
	* tao/Strategies/SHMIOP_Profile.cpp:
	* tao/Strategies/SHMIOP_Profile.h:
	* tao/Strategies/DIOP_Profile.cpp:
	* tao/Strategies/DIOP_Profile.h: Removed create_tagged_profile ()
	  and the instance of IOP::TaggedProfile.
	  
	* tao/Invocation.cpp:
	* tao/Stub.cpp:
	* tao/ClientRequestInfo_i.cpp: Changes forced on us due to the
	  signature change above.
	
Sun Jan 26 21:41:26 2003  Balachandran Natarajan  <bala@isis-server.isis.vanderbilt.edu>

	* Mering with the main trunk and moving to a new branch. 

Sun Jan 26 21:16:14 2003  Balachandran Natarajan  <bala@isis-server.isis.vanderbilt.edu>

	* docs/Options.html: documented the new option.

Mon Jan 20 09:00:55 2003  Balachandran Natarajan  <bala@isis-server.isis.vanderbilt.edu>

	The aim of this checkin is to provide an option to configure the
	size of the dispatcher table in the Muxed_Transport_Strategy. 
	
	* tao/Client_Strategy_Factory.cpp: 
	* tao/Client_Strategy_Factory.h: Added a new virtual method to
	  fetch the dispatcher table size

	* tao/default_client.cpp:
	* tao/default_client.h: Concrete implementation for the new
	  virtual method. The default value for the dispatcher table size
	  is set to TAO_RD_TABLE_SIZE which is defined in orbconf.h. The
	  table size can also be changed at runtime using a -ORB option
	  which is explained below. 

	  We now have an option called -ORBReplyDispatcherTableSize which
	  will parse and set a user provided value as the dispatcher table 
	  size. This gives extra flexibility to the user.
	  
	* tao/orbconf.h: Added TAO_RD_TABLE_SIZE and set the value to be
	  16.
	
	* tao/Muxed_TMS.cpp:
	* tao/Muxed_TMS.h: All the above changes were motivated to reduce
	  the size of the hash table that this class creates increasing
	  the run-time footprint. The default value of 1024 was probably
	  an over kill for this class.
