 Urgent  
 ======  
  
     -   Add CIMOM handle to provider interface.      -   Get rid of usage of System (use since it
  
     -   Fix case sensitivity problems in repository (just add an _Open method      -   Migrate to use of Linkage.h files.
         that ignores the case of the file).  
  
     -   Add newly implemented repository operations to protocol and to      -   Document that lex and yacc are no longer a requirement to build
         dispatcher.          Pegasus.
  
     -   Change INVALID_CLASS exceptions to NOT_FOUND (they're wrong in      -   Figure out how to handle very large CIM respones and possibly
         Repository).          requests too.
  
     -   Add tracing of output HTTP messages.      -   Integrate client/server tests into make system somehow.
  
     -   Need CIMInstance::removeMethod() and CIMInstance::removeProperty().      -   Note that it is possible to remove an class and still have association
           classes which refer to it.
  
 Topical To-Do List      -   Class inheritance not taken into consideration when resolving the
 ==================          AssocClass
  
     -   Provide way of printing out command line options help from cimserver.      -   It seems that associatios() will fail when AssocClass is a super
           class of the class which is in the association instance table.
  
     -   GetInstances() and GetClasses() need to use iterators on      -   Should there be a single associations table for the entire repository
         provider and repository end. Otherwise, all classes or instance          or should there be one per namespace as there is now?
         to be enumerated, must be sucked into memory.  
  
     -   Template bloat reduction.      -   If it is the case that a reference may only refer to an instance,
           then we must derive new types for representing object paths.
     -   Use YACC on Linux.  
   
     -   Need a tool to say which features are supported by a compiler.  
  
     -   Support unloading of dynamic libraries (presently only load() is      -   Many CIM operations interfaces are incorrect: GetInstance() for example
         supported).          takes a namespace and a CIMReference (which also may contain the
           namespace). According to the standard, it should take an "InstanceName".
  
 -   Instances:      -   Need way of signaling the cimserver so that it will reload the
           class inheritance table (after a MOF compile).
  
     -   Implement CIMRepository::getProperty()      -   Revisit use of namespace v.s. objectName in all CIM operations.
  
     -   Implement CIMRepository::setProperty()      -   What do we do when getInstance() is called and the nameSpace is
           provided both as an argument and as part of the instance name?
  
     -   Implement CIMRepository::deleteInstance()      -   ReferenceNames should return classes not just instances?
  
     -   Implement CIMRepository::modifyInstance()      -   Remove final const from const methods in non-const CIM element classes.
  
     -   Implement CIMRepository::enumerateInstances()      -   Null vs. empty CIM/HTTP parameters.
  
     -   Implement CIMRepository::enumerateInstanceNames()      -   Resolve constness problems. (get rid or Const classes?)
  
     -   Handle inheritance in all instance operations.      -   Change CIMReference to CIMObjectPath?
  
     -   Double check that all these operations work across protocol.      -   Finish associations.
  
     -   Check that they have keys during validation.      -   Provide CIMOM Context.
  
 -   Associations:      -   Complete conventions document.
  
     -   Implement CIMRepository::referencesOf()      -   The CIMServer.exe program should probably create the logs directory
           under PEGASUS_HOME.
  
     -   Implement CIMRepository::associatorsOf()      -   Clean up exceptions.
  
     -   Implement protocol stubs for these operations.      -   Resolve redundancy in which the namespace is passed to certain methods
           (getClass) and the CIMReference itself may contain a namespace arguent.
  
 -   Exceptions:      -   Implement consistency and constraint checking on classes and instances.
  
     -   Force __FILE__ and __LINE__ argument on every usage of CIMException.      -   Implement filtering (using includeQualifiers, localOnly, etc.)
  
     -   Clean up and consolidate exception classes.      -   Consider eliminating const CIM element classes.
  
     -   Propagate underlying error messages across the CIM protocol.      -   Support for NULL property lists (in interface and protocol).
  
 -   References:      -   Rename tests (prepend "Test" to each test).
  
     -   Validate arguments to CIMReference compound constructor and modifiers.      -   Fix bug with cimserver.exe causing it to fail to start without te
         (namespaces, hosts, classnames, and keybindings)          "-l" option.
  
     -   Be sure that escape sequences are handled inside of object names. For      -   Resolve whether the backslash should be permitted in namespaces.

     -   The TCPChannel::writeN() method blocks when the client and server      -   Develop BinaryEncodings module.
         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.      -   Develop MOFEncodings module.
  
     -   Provide ACE Channel implementation (for porting purposes)?      -   Employ BinaryEncodings module in repository (reduce disk usage).
