CHANGE LOG FOR PEGASUS

Version 1.1.1 - 3 August 2001 - Development Branch (Work in Progress)

current working dev branch of build

1. (Karl) 6 Aug - extend ToMof functions. The MOF for a class can now be

seen as part of CGIclient class displays.

2. (Karl) 7 Aug - Update CIM25 Schema from the "preliminary" version

to the final version in Schemas\CIM25. This included minor

corrections, etc and a couple of file changes. This is the

official final CIM 25 schema relesed by the DMTF. This change

should not affect any current work.

3. (Karl) 7 Aug 2001 - Added CIM Schema 2.6 (preliminary) to the Schemas

directorys. Note however that today the make repository still

loads the 2.5 schema.

4. (Karl) 8 Aug 2001 - Change cimmofparser.cpp to put header and trailers

on XML output.

5. (Denise Eckstein - HP) 13 Aug 2001 - Fixed an HP-UX compile problem

in various src/utils/mu commands (MoveCmd.cpp, PrependCmd.cpp, RmCmd.cpp,

RmDirHierCmd.cpp, StripCmd.cpp, TouchCmd.cpp). aCC scopes variable

declarations in for loop initializers outside the loop, so multiple

"for (int i=0; i<10; i++);" statements cause a compile error.

6. (Nag Boranna - HP) 15 Aug 2001 - Modified Config framework to remove

dependency on the config files at the start of the cimserver. Now the

cimserver will use in-memory default values in the absence of config files

and command line options. Fixed a few defects in the config framework that

were causing cimom to crash under certain conditions. Changed the config

provider class name to 'PG_ConfigSetting' in the mof file and modified

provider implementation files accordingly. Also modified the config CLI

to show user friendly error/status messages.

7. (Carol Ann Krug Graves - HP) 16 Aug 2001 - Fixed a bug in wbemexec CLI

(reported incorrect line number on error in XML request if input redirected).

Enhanced the -d debug command line option to allow more flexibility in

generating debug output.

8. Karl 17 Aug 2001) - Extended CIMMOF compiler to put pegasus comment line in

xml when it generates xml output.

9. (Roger Kumpf - HP) 20 Aug 2001 - Combine instances of each class into

a common file to reduce the number of files required by the default

repository implementation.

10. (Mike Brasher) - Fixed minor bug in repository implementation.

11. (Mike Brasher) - Committed fix to missing PARAMETER.REFERENCE XML element.

12. (Mike Brasher) - Committed rework of server into queue approach.

13. (Mike Brasher) - New webserver and webclient examples.

14. (Sushma Fernandes - HP) 21 Aug 2001 - Fixed a bug that was creating an empty file when trace was not enabled. Changed the Tracer test program's executable file name to TracerTest instead of Tracer.

15. (Mike Brasher) - Initial work on refactorying client into modules.

CIMOperationRequestEncoder and partial CIMOperationResponseDecoder.

16. (Mike Brasher) - queue-based clients now complete.

17. (Jim Chou - HP) 12 Sep 2001 - Initial contribution of wbemexec test directory and make infrastructure. This submittal also includes an initial set of test scripts.

18. (Markus Mueller - IBM) 13 Sep 2001 - Initial support for z/OS on z/Series, the successor of OS/390 and MVS.

19. (Warren Otsuka - HP) 14 Sep 2001 - Implementation of servlet web server

interface to CIMServer.This is for the PEGASUS CIM Server to coexist with

a web server. See doc/Servlet for more information.

20. (Yi Zhou - HP) 20 Sep 2001 - Added tracing in files

CIMOperationRequestDecoder.cpp and CIMOperationResponseEncoder.cpp so XML

input and output can be written in a trace file.

21. (Markus Mueller - IBM) 25 Sep 2001 - Initial Signal Handler support

Created new class SignalHandler that allow registration, activation and

deactivation of signal handler functions (Linux only !).

22. (Nitin Upasani - HP) 27 Sep 2001 - Modification of ExportServer and

ExportClient to support ExportIndication. DisplayConsumer, a sample

consumer is added which will consume (by displaying on screen) the

indication exported by CIMExportRequestDispatcher. This complete

implementation is based on CIM_EXPORT_INDICATION_REQUEST and

RESPONSE messages. CIMMessage.h, Message.cpp and Message.h files

are modified to implement above messages.

XmlIndicationDispatcher test program is modified to test complete

operation. It now creates a consumer, handler and indication

instance and then calls CIMExportRequestDispatcher to export the

indication to consumer. This program needs

src/Pegasus/Server/tests/XmlIndicationDispatcher/TestSoftwarePkg.mof

and Schemas/Pegasus/PG_ConsumerRegistration.mof files to be loaded

in the repository to complete the test successfully. This test

program also needs Handler qualifier defined in repository and

modify CIM_Event25.mof for CIM_IndicationHandlerXMLHTTP class as

below:

//====================================================================

// CIM_IndicationHandlerXMLHTTP

//====================================================================

[Description (

"CIM_IndicationHandlerXMLHTTP describes the destination for "

"Indications to be delivered via HTTP, using a cimXML "

"representation."), Handler ("CIMxmlIndicationHandler") ]

23. (Sushma Fernandes - HP) 27 Sep 2001 - Added tracing code in

ProviderTable.cpp and SystemUnix.cpp to indicate progress of loading

a provider library.

24. (Nitin Upasani - HP) 05 Oct 2001 - implementation of InvokeMethod

interface for the provider. InvokeMethod currently uses CIMValue as

type for inParameters and outParameters, which are unable to give

information about param name, type and value. This should be changed

to CIMParamValue which will help providers to know details of the

parameter name and type along with value passed through InvoleMethod

call. Current implementation uses CIMParamValue as parameters while

travelling through message queues and converts it back to array of

CIMValue before calling Provider API (which needs to be changed

later).

Also added are two test programs:

src/Pegasus/Common/tests/ParamValue - which demonstrate use of

CIMParamValue class.

src/Pegasus/Client/tests/InvokeMethod - which makes call to

InvokeMethod and displays the return value. Current

implementation assumes that provider had returned true value

and outParameters (which are now hard coded in

CIMOperationRequestDispatcher to implement functionality)

which are passed as response of InvokeMethod to client.

25. (Nag Boranna - HP) 05 Oct 2001 - Added first level implementation of

authentication to the pegasus code. Created an Authentication Manager

and authenticator interfaces. The file based local authentication

module has been modified to implement the local authenticator

interface, to generate the challenge for the unauthorized requests

and to verify the authentication.

A skeleton program has been created for the Basic Authenticator.

This code is in the Security/Authentication directory which is not

yet linked into the build.

26. (Nitin Upasani - HP) 08 Oct 2001 - Changes to Operation and Export

Decoders. Earlier decoders were sending requests and responses

before finishing complete Xml parse. This was prone to send

request/response even the Xml is wrong after the MethodCall.

New changes collects the Message* as return value from the

appropriate functions while parsing the Xml and sends on

_outputQueue only when Xml is parsed successfully.

27. (Nag Boranna - HP) 11 Oct 2001 - Modified ProviderModule.cpp to

fix the problem with constructing provider name and loading the

providers for unix platforms. Also moved the shared library name

construction (appending .sl or .so) from

CIMOperationRequestDispatcher.cpp/SystemUnix.cpp to

ProviderModule.cpp and included it in a method that returns

provider file path name.

28. (Nitin Upasani - HP) 12 Oct 2001 - Implementation of SNMP Indication

Handler. This handler extracts MappingStrings qualifier from class

definition and converts it into SNMP specific trap data. The trap

structure is defined in a abstract class in snmpDeliverTrap.h file.

Every one has his or her own SNMP agent, which will talk with master

agent to deliver the trap or may have some other mechanism.

Extending snmpDeliverTrap class and deliverTrap method will help to

implement specific trap delivery mechanism.

29. (Yi Zhou - HP) 09 Oct 2001 - Changed cimconfig to allow setting property to

be NULL. Also, if -u -p specified in the cimconfig, instead of updating

property value to be default in the plan file, remove the property from the

plan file. Converted ConfigSettingProvider to use provider2 library.

30. (Sushma Fernandes - HP) 24 Oct 2001 - Added an interface to the tracer

to allow tracing of a specific number of bytes in a given

string. Also modified the XmlIO trace code to use the new interface.

Changed the config file defaults for tracing.

31. (Rudy Schuet - Compaq) 28 Oct 2001 - Added "make" support for Compaq

NonStop platform (NSK) in directory pegasus/mak. The following files

were added: platform_NSK_NONSTOP_NMCPLUS.mak, objects-nsk.mak,

library-nsk.mak, config-nsk.mak, program-nsk.mak, program-windows.mak,

program-unix.mak. The original program.mak which previously covered

all platforms was split into platform-specific make files, and now

only contains conditionals. Files config.mak, objects.mak, and

library.mak were changed to include the NSK files.

File platform_NSK_NONSTOP_NMCPLUS.mak includes config-nsk.mak.

32. (Jenny Yu - HP) 29 Oct 2001 - Fixed CIMReference constructor to allow

commas (,) in the string values of key properties.

33. (Karl Schopmeyer) 30 October 2001- Move the repository load to CIM schema 2.6

34. (Rudy Schuet - Compaq) 30 Oct 2001 - Fixed a problem in

pegasus/mak/program-windows.mak that prevented program builds for

the windows platform (related to change from 28 Oct). Replaced

leading whitespace in front of commands with tabs as required

in make files.

35. (K Schopmeyer 2 Nov 2001)Temporarily moved repository back to CIM25

because getting an error in 26

35. (Roger Kumpf - HP) 30 Oct 2001 - Association classes have keys

whose types are references. These reference values must be

treated specially in the XML encoding, using the VALUE.REFERENCE

tag structure.

Pegasus had been passing reference values simply as String values.

For example, EnumerateInstanceNames returned KEYVALUEs of string

type rather than VALUE.REFERENCEs.

I've modified the XmlReader::getKeyBindingElement() and

CIMReference::instanceNameToXml() methods to read and write the

XML in the proper format. However, making that change required

that a CIMReference object be able to distinguish between a key

of String type and a key of reference type.

I've modified the String format of CIMReferences slightly to

allow efficient processing of references whose keys are also of

reference type. The "official" form uses the same encoding for

key values of String type and of reference type, and so it

would be necessary to retrieve the class definition and look up

the types of the key properties to determine how to treat the

key values. This is clearly too inefficient for internal

transformations between CIMReferences and String values.

The workaround is to encode a 'R' at the beginning of the value

for a key of reference type (before the opening '"'). This allows

the parser to know a priori whether the key is of String or

reference type.

In this example:

MyClass.Key1="StringValue",Key2=R"RefClass.KeyA="StringA",KeyB=10"

Property Key1 of class MyClass is of String type, and so it gets

the usual encoding. Key2 is a reference property, so the extra 'R'

is inserted before its encoded value. Note that this algorithm is

recursive, such that RefClass could include KeyC of reference type,

which would also get encoded with the 'R' notation.

The toString() method inserts the 'R' to provide symmetry. A new

KeyBinding type (REFERENCE) has been defined to denote keys in a

CIMReference that are of reference type. This KeyBinding type must

be used appropriately for CIMReference::ttoString() to behave

correctly.

The files that have been modified to make this change are

CIMReference.h, CIMReference.cpp, and CIMInstanceRep.cpp.

A result of this change is that instances names in the instance

repository will include this extra 'R' character. Thus, you will

need to repopulate your repository when you download the latest

CIMOM version.

Note that for user-facing uses of the String encoding of instance

names (such as might appear in MOF for static association

instances or in the CGI client), this solution is non-standard and

therefore unacceptable. It is likely that these points will need

to process the more expensive operation of retrieving the class

definition to determine the key property types.

Version 1.1 - July 2001 Development branch (Work in PRogress)

Version 1.1 - July 2001 Development branch

Tagged as version_1_01 on 3 August 2001 (sorry should have been

1.1

1. (Nitin Upasani - HP) Implementation of handleIndication() to deliver

indication by defining IndicationDispatcher, HandlerTable, CIMHandler

and ExportClient classes. the indication.

Also implemented CIMxmlIndicationHandler and sendmailIndicationHandler to

make the delivery of indications over Xml-HTTP and email respectively.

Provided examples for HandlerTable, XmlIndicationDelivery and

SendMailIndicationDelivery to support this implementation.

2. (Markus Mueller - IBM) Implementation of a Linux specific threading

library and a thread-safe message queue (first stage). Classes defined

are Mutex, Condition, Semaphore, AtomicInt, ReadWriteSem, cleanup_handler

and SimpleThread.

3. (Carol Ann Krug Graves - HP) Implementation of wbemexec CLI. Please refer

to the man page in pegasus/src/Clients/wbemexec/doc/wbemexec.html for more

information on using wbemexec. A simple test script is included. Please

see pegasus/src/Clients/wbemexec/tests/readme for information on running

the test script.

4. (Sushma Fernandes - HP) Implementation of Trace Framework. Please

refer to the documentation in src/Pegasus/Common/doc/TracingDevGuide.pdf

and

src/Pegasus/Common/doc/TracingUserGuide.pdf for more information on using

the Trace framework. Classes defined are src/Pegasus/Common/Tracer.cpp and

src/Pegasus/Common/TraceFileHandler.cpp.

5. (Nag Boranna - HP) Implementation of Config Framework, Config Provider and

Config CLI. Please refer to the documentation

in pegasus/doc/WorkPapers/CIMOMConfigurationWorkPaper.pdf and the man page

in pegasus/src/Clients/cimconfig/doc/cimconfig.html for more information on

using the config framework and cimconfig CLI. Make sure to load the config

mof (src/gmake config) before starting the cimserver. A simple test script

is included. Please see pegasus/src/Clients/wbemexec/tests/readme for

information on running the test script.

6. (Karl Schopmeyer 31 July 2001) - Add toMof functions to the CIM objects

(changed the H and CPP files for the major CIM objects. These

functions generate CIM MOF output for the objects.

7. (Bapu Patil - HP) Implementation of Local Channel Authentication. Local

Authentication provides security mechanism to authenticates CIM clients

that

connect to CIM Server on the same system without having to specify a

password.

Please refer to "doc/LocalCIMSecurity.pdf" for more information on design.

This component only works on unix and it's not linked in with the main

build.

When authentication framework is defined this component may need to be

modified to integrate with the framework.

8. (Sushma Fernandes - HP) Removed the ltoa() function call from Tracer.cpp.

Added a constant to define the maximum length of uint32.
