           (namespaces, hosts, classnames, and keybindings)
   
       -   Be sure that escape sequences are handled inside of object names. For
           example:
   
               X.key1="Hello \"You\""
   
   -   Protocol:
   
       -   Improve protocol tracing to show messages in both directions.
  
     -   The TCPChannel::writeN() method blocks when the client and server     -   The TCPChannel::writeN() method blocks when the client and server

         anything as long as writeN() is blocked on a synchronous write.         anything as long as writeN() is blocked on a synchronous write.
  
     -   Should ChannelHandler::handleOpen() do the registration with the

     -   Figure out how to handle getProperty() return type.     -   Figure out how to handle getProperty() return type.
  
     -   Having problems with reference on Repository::createInstance() and      -   Provide ACE Channel implementation (for porting purposes)?
         Repository::getInstance(). References not always in standard form.  
         Also, resolve() fails when instance has properties of difference  
         case.  
   
     -   Super class name does not seem to be set in enumerateClasses  
         operation.  
   
     ------------------------------------------------------------------------  
   
     -   Remove "std::" qualifiers and use a macro and use #define for  
         PEGASUS_NAMESPACE_STD.  
   
     -   Change getLength() to length() or size()?  
   
     -   Change find<Object> to find<Object>ByIndex().  
   
     -   Need get by name.  
   
     Now:  
   
     -   Add convenience functions: addProperty().  
     -   Change CimException to CIMException  
     -   Get ACE working on Tandem (or remove ACE from Pegasus).  
     -   Port Pegasus to Tandem (look for Tandem machine at BMC).  
     -   Instance repository.  
     -   Delete namespace.  
     -   Finalize provider interface.  
     -   Associations (basic).  
     -   Provider registration (by the standard).  
     -   MOF compiler (finalize).  
     -   Write short paper on Pegasus data objects.  
     -   Integrate DOC++ with make system.  
     -   Compaq requested SQL level-1 description.  
     -   Get rid of ACE (required if no ACE on Tandem).  
     -   Need query capability for Compaq.  
     -   Threading (and process forking).  
     -   Implement protocol module (the default uses ACE).  
     -   Package up pegasus in Install Shield application.  
  
       -   Handle PARAMETER.REFARRAY in Procotol?
  
     ------------------------------------------------------------------------      -   Ignore extraneous XML elements (loosely valid).
  
     (A) Install shield install of Pegasus.  -   Porting:
  
     (A) Handle escaping of strings inside object names. Example:      -   Replace "std::something" with "STD(something)"
  
                 X.key1="Hello \"You\""      -   Replace "using namespace std" with "USING_NAMESPACE_PEGASUS"
   
   -   Aesthetics/Consistency/Usability:
   
       -   Change getLength() and getSize() to just size(): "Brevity is the soul
           of genius and of Lingerie".
   
       -   Add methods to get objects by their names, in addition to index. For
           example:
   
               CIMProperty CIMClass::getProperty(const String& name);
   
       -   Perform walkthrough to expose consistency problems.
   
       -   Distinguish between private and public classes (otherwise, users may
           come to depend on classes with unstable interfaces).
   
   -   Documentation:
   
       -   Suggest newlines after methods.
   
       -   Suggest use of "/** ... */" instead of "///"
   
       -   Refine header file documentation.
   
       -   Write Pegasus Architecture Paper.
  
     (A) Notice that there is a bug where you select Scope::REFERENCE and      -   Integrate DOC++ with make system (put all docs in doc tree):
         and the validation routines still say the scope is wrong for  
         qualifiers applied actual references (they are checking for  
         property instead).  
  
     (A) There is an odering problem when applying the qualifiers with  -   Namespaces:
         association scope to classes. If the association qualifier does not  
         come first, then application of prior qualifiers fail.  
         Checking this should be moved to class resolution.  
  
     ------------------------------------------------------------------------      -   Implement create and destroy namespace (according to the standard).
  
     (B) Hide setPropagated() and setClassOrigin() methods (only the resolve  -   Providers
         method should touch these).  
  
     (B) Change make system to rename dll's before link so that they      -   Add CIM-Server handles to provider interface.
         can be used by the server.  
  
     (B) Finish other CIM/HTTP protocol operations.      -   Implement MOF provider registration scheme (according to the standard).
  
     (B) Use the description that comes back with an error code in the XML  -   WBEM Query Language
         protocol. Perhaps it should become an extra message field of  
         XmlException.  
  
     (B) Source documentation.      -   Find someone to work on standard.
   
       -   Implement leve-1 parser.
   
   -   MOF compiler:
   
       -   Work with Bob to identify work items.

           provider).
   
       -   Implement queuing.
   
       -   Make reference counted objects thread safe (Mutexing and atomic
           increments).
   
   -   Connectors
   
       -   Work out basic concepts (write paper).
   
       -   Package up pegasus in Install Shield application.
  
     (B) Put README in each directory.  
  
     (B) Handle UCS2 characters in XML (parsing and writing).  -   Install
  
     (B) Check for overflow on the number of attributes in XML.      -   Need install mechanism for Unix and Windows.

     (C) Develop XML repository importation mechanism.  -   Constraint hanlding
  
     (C) Move internal headers to ./internal directory      - Enforce constraint qualifiers.

     (C) Devise a way to detect whether a class has instances.      -   Shrink object sizes.
  
     (C) Cleanup of execeptions.      -   Use lighter I/O system (than C++ streams).
  
     (C) Verify that fixed length arrays are properly handled.      -   Run Purify on all sources (port to Sun first).
  
     (C) Check for null string pointers in String class.      -   Optimize clear method on arrays (to not release memory).
  
     (C) Verify that instances are property keyed (during validation).  -   Porting
  
     (C) Thread safety.      -   Port to Solaris

     (C) Purify source.      -   Run CIM/XML test suite.
  
     (C) Improve the representation of fixed arrays (is that pesky fixed-array  -   Server
         flag really necessary?)  
  
     (C) Modify clear() methods on Array and String so that they don't      -   Use Service class in cimserver
         release the old resource (more efficient for GetLine()). Add  
         a resize() method.  
  
       -   Implement Service class on Unix (daemonization from Comer book).
