18 (KS) 6 March 2002 - Implemented changes to compiler and flavors to correct the

definition of CIMFlavors.

19. (Roger Kumpf - HP) 1 Mar 2002 - Reworked the XmlWriter class to

eliminate many of the redundant memory copies that resulted from the

nested method call structure. Now, instead of having a method at

each level that adds a begin tag, contents, and an end tag, there

are separate methods to add the begin and end tags. At the top

level, each of the begin tag methods are called, then the message

"body" is added, followed by calls to the end tag methods.

The message body is currently still copied twice, once into the XML

payload and then again when the HTTP header is added. (Since the

HTTP header contains a content length field, the header cannot be

constructed until the payload is complete.) It is possible to

remove these extra copies as well, but that would require additional

changes elsewhere in the code. For example, the HTTPMessage class

would need to hold the headers and payload separately rather than in

a single buffer.

Along with these changes, I did a lot of cleanup. Much of the XML

formatting code has been moved from CIMReference to XmlWriter. Also,

error message formatting has been consolidated in XmlWriter from the

various encoders and decoders, etc.

20. (Roger Kumpf - HP) 5 Mar 2002 - Added checks in the

CIMOperationRequestDecoder and CIMExportRequestDecoder to validate

that the information in the HTTP headers of a request is consistent

with what is encoded in the XML request itself.

Specifically, the CIMOperation, CIMProtocolVersion, CIMMethod,

CIMObject, CIMBatch, CIMExport, and CIMExportBatch headers are

validated.
