+
+	This set of changes comes with complete revamping of the previous
+	design. The flaws with the previous design were as follows
+	(1) We were unnecessarily penalising large data blocks. We were
+	    trying to read a particular size of data till the data was
+	    completely removed from the socket. This was totally
+	    ridiculous because we were doing more reads than required.
+
+	(2) The message block that was constructed on the stack with a
+	    buffer from stack never did what we wanted. It was allocating
+	    a data block on the heap and was thus spoiling whatever
+	    optimization that we had tried putting in.
+
+	(3) The incoming message Queue is now managed by the TAO_Transport
+	    object instead of the GIOP classes.
+
+	* tao/GIOP_Message_Base.cpp:
+	* tao/GIOP_Message_Base.h: Removed the references to the incoming
+	  message queue. Implemention for two methods missing_data () and
+	  byte_order (). Added an extra argument to the methods
+	  process_request_message () and process_reply_message (). Used
+	  the incoming message block to create a input CDR with the
+	  DONT_DELETE flag so that the data block is not deleted after
+	  request processing.
+
+	* tao/GIOP_Message_State.cpp: Removed the inclusion of
+	  Transport.h.
+
+	* tao/Incoming_Message_Queue.h:
+	* tao/Incoming_Message_Queue.cpp:
+	* tao/Incoming_Message_Queue.inl: Added an argument to the
+	  add_message (). Further the implementation of add_message () has
+	  changed a bit. It now adds only a new message to the queue. It
+	  doesn't modify a half filled queue. The TAO_Transport object
+	  does that job. So declared the TAO_Transport as the friend class
+	  of the Incoming_Message_Queue.
+
+	  Changed the name of the methods complete_message () as
+	  is_complete_message (). Removed the methods current_message ()&
+	  current_byte_order ().
+
+	  Added a new method copy_message () which copies messages into
+	  the half empty nodes.
+
+	  Added a method wr_ptr () to access the write pointer of the tail
+	  node that has halfempty message.
+
+	* tao/Transport.cpp:
+	* tao/Transport.h: The Incoming Message Queue is now managed by
+	  this class. Added the following methods
+	  - missing_data ()
+	  - parse_incoming_messages ()
+	  - check_message_integrity ()
+	  - consolidate_message ()
+	  - conslodate_message_queue ()
+
+	* tao/Pluggable_Messaging.h: Added two new virtual functions
+	  missing_data () and byte_order ().
+
+	* tao/ORB_Core.h:
+	* tao/ORB_Core.cpp:
+	* tao/ORB_Core.i: Added an accessor for the locking_strategy used
+	  for the CDR blocks.
+
+	* tao/Synch_Reply_Dispatcher.cpp:
+	* tao/Asynch_Reply_Dispatcher.cpp:
+	* tao/DynamicInterface/DII_Reply_Dispatcher.cpp: Changed the
+	  exchange_data_block () to clone_from () which is a new method in
+	  ACE_InputCDR.
+
+	* tao/LIST_OF_TODO: Updated the list

+
+	* tao/Incoming_Message_Queue.cpp:
+	* tao/Incoming_Message_Queue.inl: Fixed a bad way to use the tail
+	  of the circular linked list. This is now replaced by the size of
+	  the linked list. This fixes quite a few errors.
+
+	* tao/Transport.cpp: On read () if we get errno === EWOULDBLOCK we
+	  were closing the connection prematurely. This is not right. We
+	  should only return a 0 to the reactor, so that it can call us
+	  back when there is data in the socket.
+
+Wed Jun 13 10:45:24 2001  Balachandran Natarajan  <bala@cs.wustl.edu>
+
+	* tao/GIOP_Message_Base.cpp (process_reply_message): Fixed the
+	  reply parsing and generation of the CDR stream that is passed on
+	  to the higher layers of the ORB.
+
+Wed Jun 13 07:25:24 2001  Balachandran Natarajan  <bala@cs.wustl.edu>
+

+
+	* tao/GIOP_Message_State.h:
+	* tao/GIOP_Message_State.inl: The message_size () now returns the
+	  payload size + the GIOP header length. Added a new method
+	  payload_size () that returns the payload size alone.
+
+	* tao/GIOP_Message_Base.cpp: Fixed a warning with g++ builds.
+
+	* tao/Connection_Handler.h:
+	* tao/Connection_Handler.cpp: The svc_i () method now calls
+	  handle_input_i () on the transport instead of the method in the
+	  same class. The handle_input_i () in the TAO_Connection_Handler
+	  class has been removed as it is no longer used.
+
+	* tao/IIOP_Connection_Handler.h:
+	* tao/IIOP_Connection_Handler.cpp: Removed the implementation of
+	  handle_input_i ().
+
+	* tao/Incoming_Message_Queue.cpp: When trying to make a new data
+	  block we dont add the size of GIOP header. The message_size ()
+	  now returns with that value.
+
+	* tao/Incoming_Message_Queue.inl: Fixed a link error in g++
+	  builds.

+
+	First set of checkins for big two ways.
+
+	* tao/Connection_Handler.h: Added #define for the default
+	  buffer size . Not sure yet whether this is the right place for
+	  it.
+
+	* tao/Incoming_Message_Queue.h:
+	* tao/Incoming_Message_Queue.cpp:
+	* tao/Incoming_Message_Queue.inl: Queue up the incoming
+	  messages. We form a circular linked list of messages that are
+	  bigger than a particular buffer size. During processing we take
+	  messages of the queue to pass it onto the higher layers of the
+	  ORB.
+
+	* tao/GIOP_Message_Base.cpp:
+	* tao/GIOP_Message_Base.h: Added support for big two way
+	  requests. If the message has only been partially read we add the
+	  message in the queue and then go for the next read. During
+	  processing we check if the queue has messages before processing
+	  the message on hand.
+
+	* tao/GIOP_Message_State.h:
+	* tao/GIOP_Message_State.cpp:
+	* tao/GIOP_Message_State.inl: Added accessor methods.
+
+	* tao/Transport.cpp: Added support for bigger two ways. If we
+	  receive a two way bigger than a particular size we read and
+	  queue the message and do a further read to retrieve the rest of
+	  the message.
+
+	* tao/TAO.dsp: Added new files.
+	* tao/default_resource.cpp: For single threaded configuration we
+	  have been creating a locked data block and that seems to defy
+	  logic. We now should create a lock free datablock for single
+	  threaded configurations.
+
+Sat Jun  2 12:02:55 2001  Balachandran Natarajan  <bala@cs.wustl.edu>
+
+	* tao/* : Merged with the main trunk.
+
+Fri Jun  1 17:22:29 2001  Balachandran Natarajan  <bala@cs.wustl.edu>
+
+	* tao/GIOP_Message_State.cpp (parse_message_header_i):
+	* tao/Connection_Handler.cpp:
+	* tao/GIOP_Message_Base.cpp:
+	* tao/Makefile:
+	* tao/Transport.cpp: Fixed warnings and errors in Linux g++.
+
+Thu Jun 01 13:39:02 2001  Balachandran Natarajan  <bala@cs.wustl.edu>
+
+	* tao/Transport.cpp:
+	* tao/Transport.h:  Added the following methods -- handle_input_i
+	  (), process_parsed_message (). The handle_input_i () creates a
+	  buffer on the stack. It uses the buffer to read the
+	  messages. Any errors in read () or dealt here directly. The read
+	  message is then parsed and processed by the GIOP classes. Moved
+	  most of the code for processing here as they seem to be common
+	  between different transport protocols. Once we have received a
+	  full message, we just resume the handler and go ahead with
+	  processing the message.
+
+	* tao/IIOP_Connection_Handler.cpp (handle_input ()): Calls
+	  handle_input_i () on the transport.
+
+	* tao/Connection_Handler.h:
+	* tao/Connection_Handler.cpp:  The svc_i () calls the
+	  handle_input_i () on the transport instead of the same call on
+	  the connection handler. This way we should be able to share the
+	  same code among different protocol objects.
+
+	* tao/GIOP_Message_State.h:
+	* tao/GIOP_Message_State.cpp: Much of the message parsing and
+	  state information is stored here.
+
+	* tao/GIOP_Message_Base.h:
+	* tao/GIOP_Message_Base.cpp:
+	* tao/Pluggable_Messaging.h: made some changes to suit the
+	  above. But more changes could come in, to suit different
+	  protocols. We may want to change the interfaces in
+	  Pluggable_Messaging to give a much cleaner interface to the
+	  world.
+
+	* tao/Wait_On_Read.cpp: Used the handle_input_i () on the
+	  transport for processing the incoming data.
+
+	* tao/TAO.dsp:
+	* tao/PortableServer/TAO_PortableServer.dsp: Added new files and
+	  removed files from GIOP_Lite in the first round.
+
+	* tao/GIOP_Message_Reactive_Handler.cpp:
+	* tao/GIOP_Message_Reactive_Handler.h: Looks like these files
+	  would be removed during the final merge.
+
+	The above checkins works for simple two way calls. The
+	BiDirectional_NestedUpcall test works with the TP_Reactor. This
+	works on Win32.
+
+
+Thu May 24 12:19:02 2001  Balachandran Natarajan  <bala@cs.wustl.edu>
+
+	* tao/Transport.h: Added some design forces for the input data
+	  path.
