 Urgent  
 ======  
  
     -   Add CIMOM handle to provider interface.      -   Figure out how to handle very large CIM respones and possibly
           requests too.
  
     -   Fix case sensitivity problems in repository (just add an _Open method      -   Integrate client/server tests into make system somehow.
         that ignores the case of the file).  
  
     -   Add newly implemented repository operations to protocol and to      -   Note that it is possible to remove an class and still have association
         dispatcher.          classes which refer to it.
  
     -   Change INVALID_CLASS exceptions to NOT_FOUND (they're wrong in      -   Class inheritance not taken into consideration when resolving the
         Repository).          AssocClass
  
     -   Add tracing of output HTTP messages.      -   It seems that associatios() will fail when AssocClass is a super
           class of the class which is in the association instance table.
  
     -   Need CIMInstance::removeMethod() and CIMInstance::removeProperty().      -   Should there be a single associations table for the entire repository
     -   Add a exists namespace operation under the repository stuff.  Maybe we          or should there be one per namespace as there is now?
     need more than this.  
  
 Topical To-Do List      -   If it is the case that a reference may only refer to an instance,
 ==================          then we must derive new types for representing object paths.
  
     -   Sun uses string message-ids. Pegasus uses integer.      -   Many CIM operations interfaces are incorrect: GetInstance() for example
         Sun uses 2000.5.12.... format. Changed Pegasus to          takes a namespace and a CIMReference (which also may contain the
         use string message-ids. DONE.          namespace). According to the standard, it should take an "InstanceName".
  
     -   Some clients send '\n\n' to terminate HTTP headers.      -   Need way of signaling the cimserver so that it will reload the
         We were only accepted '\r\n\r\n'. DONE.          class inheritance table (after a MOF compile).
  
     -   Provide way of printing out command line options help from cimserver.      -   Revisit use of namespace v.s. objectName in all CIM operations.
  
     -   GetInstances() and GetClasses() need to use iterators on      -   What do we do when getInstance() is called and the nameSpace is
         provider and repository end. Otherwise, all classes or instance          provided both as an argument and as part of the instance name?
         to be enumerated, must be sucked into memory.  
  
     -   Template bloat reduction.      -   ReferenceNames should return classes not just instances?
  
     -   Use YACC on Linux.      -   Remove final const from const methods in non-const CIM element classes.
  
     -   Need a tool to say which features are supported by a compiler.      -   Null vs. empty CIM/HTTP parameters.
  
     -   Support unloading of dynamic libraries (presently only load() is      -   Resolve constness problems. (get rid or Const classes?)
         supported).  
  
 -   Instances:      -   Change CIMReference to CIMObjectPath?
  
     -   Implement CIMRepository::getProperty()      -   Finish associations.
  
     -   Implement CIMRepository::setProperty()      -   Provide CIMOM Context.
  
     -   Implement CIMRepository::deleteInstance()      -   Complete conventions document.
  
     -   Implement CIMRepository::modifyInstance()      -   The CIMServer.exe program should probably create the logs directory
           under PEGASUS_HOME.
  
     -   Implement CIMRepository::enumerateInstances()      -   Clean up exceptions.
  
     -   Implement CIMRepository::enumerateInstanceNames()      -   Resolve redundancy in which the namespace is passed to certain methods
           (getClass) and the CIMReference itself may contain a namespace arguent.
  
     -   Handle inheritance in all instance operations.      -   Implement consistency and constraint checking on classes and instances.
  
     -   Double check that all these operations work across protocol.      -   Implement filtering (using includeQualifiers, localOnly, etc.)
  
     -   Check that they have keys during validation.      -   Consider eliminating const CIM element classes.
  
 -   Associations:      -   Support for NULL property lists (in interface and protocol).
  
     -   Implement CIMRepository::referencesOf()      -   Rename tests (prepend "Test" to each test).
  
     -   Implement CIMRepository::associatorsOf()      -   Fix bug with cimserver.exe causing it to fail to start without te
           "-l" option.
  
     -   Implement protocol stubs for these operations.      -   Resolve whether the backslash should be permitted in namespaces.
  
 -   Exceptions:      -   Create CIMOMContext (interface to CIMOM used b the provider).
  
     -   Force __FILE__ and __LINE__ argument on every usage of CIMException.      -   Define Encoding module interface.
  
     -   Clean up and consolidate exception classes.      -   Develop XMLEncodings module.

 -   References:      -   Develop MOFEncodings module.
  
     -   Validate arguments to CIMReference compound constructor and modifiers.      -   Employ BinaryEncodings module in repository (reduce disk usage).
         (namespaces, hosts, classnames, and keybindings)  
  
     -   Be sure that escape sequences are handled inside of object names. For      -   Combine repository instances, classes, and qualifiers  into their
         example:          respective files (to reduce the number of files).
  
             X.key1="Hello \"You\""      -   Employ an efficient indexing scheme in repository (B-trees or hashing).
  
 -   Protocol:      -   Develop module manager: interface, lookup scheme, and loading scheme.
  
     -   Improve protocol tracing to show messages in both directions.      -   Package Encodings classes as a module.
  
     -   The TCPChannel::writeN() method blocks when the client and server      -   Finalize repository assocations.
         are in the same process. That is because the client cannot read  
         anything as long as writeN() is blocked on a synchronous write.  
  
     -   Figure out how to handle getProperty() return type.      -   Add association CIM/HTTP operations.
  
     -   Provide ACE Channel implementation (for porting purposes)?      -   Design association provider infrastructure.
  
     -   Handle PARAMETER.REFARRAY in Procotol?      -   Implement missing CIM protocol operations.
