options.

then we must derive new types for representing object paths.

- Put cimserver back in the makefile.

- Many CIM operations interfaces are incorrect: GetInstance() for example

takes a namespace and a CIMReference (which also may contain the

namespace). According to the standard, it should take an "InstanceName".

- Resolve whether the backslash should be permitted int namespaces.

- Need way of signaling the cimserver so that it will reload the

class inheritance table (after a MOF compile).

- Work on developer's guidlines document.

- Revisit use of namespace v.s. objectName in all CIM operations.

No STL (or other third party software).

- What do we do when getInstance() is called and the nameSpace is

Indent by three.

Always run regression tests before committing and do cvs -q update.

- Add CIMOM handle to provider interface.

- ReferenceNames should return classes not just instances?

- Fix case sensitivity problems in repository (just add an _Open method

- Remove final const from const methods in non-const CIM element classes.

Repository).

- Add tracing of output HTTP messages.

- Change CIMReference to CIMObjectPath?

- Need CIMInstance::removeMethod() and CIMInstance::removeProperty().

- Finish associations.

- Add a exists namespace operation under the repository stuff. Maybe we

need more than this.

Topical To-Do List

- Provide CIMOM Context.

==================

- Sun uses string message-ids. Pegasus uses integer.

- Complete conventions document.

Sun uses 2000.5.12.... format. Changed Pegasus to

use string message-ids. DONE.

- Some clients send '\n\n' to terminate HTTP headers.

- The CIMServer.exe program should probably create the logs directory

We were only accepted '\r\n\r\n'. DONE.

respective files (to reduce the number of files).

- Observation of client/CIMMOM connections/disconnection.

- Validate arguments to CIMReference compound constructor and modifiers.

- Observation of client/CIMOM communication.

(namespaces, hosts, classnames, and keybindings)

- Be sure that escape sequences are handled inside of object names. For

- Observation of CIMOM/repository communication.

example:

X.key1="Hello \"You\""

- Observation of CIMOM/provider communication.

- Improve protocol tracing to show messages in both directions.

- Pegasus providers for Sun WBEM Services.

- The TCPChannel::writeN() method blocks when the client and server

- Sun WBEM Services providers for Pegasus.

- Provide ACE Channel implementation (for porting purposes)?

- CIM/HTTP Proxy for WMI.
