CHANGE LOG FOR PEGASUS

Version 1.09 - Started 5 April 2002

TAG: Version_1_09.

1. 5 April 2002 (KS) Update version to 1.09. TAG, and took snapshot.

2. (Roger Kumpf - HP) 5 Apr 2002 - Modified the CIMOperationResponseMessage

class and its subclasses to contain a CIMException instead of a

CIMStatusCode and String description. This allows extra information in

a CIMException, such as file name and line number, to be carried

internally throughout the system.

This change creates a single place where CIMExceptions are converted

to an error code and description to be written out in XML. This

single place controls the ability to tune what gets included in the

error description, as well as providing a convenient place to trace

errors that get returned to clients. In particular, client applications

currently see messages that contain redundant error code information,

such as:

CIM_ERR_INVALID_PARAMETER: One or more parameter values passed

to the method were invalid: "CIM_ERR_INVALID_PARAMETER: One

or more parameter values passed to the method were invalid:

"Unrecognized parameter "Bogus"""

The CIMOperationResponseMessage change will allow the redundant

information to be eliminated from the messages.

3. (KS) 7 April 2002- Minor really bad hack to systemwindows.cpp getcurrenttime

after roger fixed timevalue.

4. (DME) 7 April 2002 Added support for HPUX running on IA64 hardware.

5. (DME) 7 April 2002 Update master result file for MOF Compiler CLI tests.

Update master result file of wbemexec CLI tests.

6. (Ramnath Ravindran - Compaq) 8 Apr 2002 - Modified a libraries.mak file in the src/Pegasus/Security/Authentication/tests directory in order to fix the

build on Tru64.

7. (Roger Kumpf - HP) 8 Apr 2002 - The RETURNVALUE and IRETURNVALUE elements

of the XML encoding of operation responses had been treated as mandatory.

The client response decoder has been updated to make those elements

optional for operations that do not require a return value. The server

response encoder has been updated not to include those elements when the

request does not include a return value.

8. (Roger Kumpf - HP) 9 Apr 2002 - Updated the Instance, Association, and

Class provider interfaces to use CIMPropertyList instead of Array<String>

for the propertyList parameters. All providers that implement a method

with a propertyList parameter must be modified in accordance with this

change. All providers linked into the Pegasus build have been updated.

9. (Roger Kumpf - HP) 11 Apr 2002 - Defined an HTTP error message to be

returned to the CIMClient when an HTTP error response is returned.

Added a method to parse the status line of an HTTP response.

10. (Roger Kumpf - HP) 11 Apr 2002 - Changed the MessageQueue::getQueueName()

method from virtual to non-virtual, and removed that method definition

from all the subclasses. To make sure that the MessageQueue class gets

the queue name value, the default value for the queue name parameter to

the MessageQueue constructor was removed. Constants were defined in

Constants.h for all the queue names currently used in Pegasus. The

places where those queue names were being used for lookup were also

changed to use the constants.

11. (Roger Kumpf - HP) 12 Apr 2002 - Defined an HTTPError exception to

report non-200-OK HTTP responses back to client applications. Added

an HTTPErrorMessage class to hold information about an HTTP error

response. Added support in the CIMOperationResponseDecoder to

process HTTP error responses and turn them into HTTPErrorMessages.

Added support in CIMClient to process HTTPErrorMessages and throw an

HTTP error. This functionality required fundamental changes in the

way CIMClient processes messages. It can no longer search its queue

for a message of the expected type. Instead, is assumes that no

messages should be on its queue unless it has sent a request to the

encoder. In that case, it assumes that any message on its queue is

the response to that request.

12. (Denise Eckstein - HP) 12 Apr 2002 - Extended versioning strategy

to allow platform-specific version strings.

13. (Denise Eckstein - HP) 14 Apr 2002 - Renamed shared library for

ManagedSystem/OperatingSystem provider so that it would not

conflict with library name of generic/OperatingSystem provider.

14. (Denise Eckstein - HP) 14 Apr 2002 - Added compile flags _REENTRANT and RWSTD_MULTI_THREAD flags for platform_HPUX_PARISC_ACC.

15. (Nag Boranna - HP) 15 Feb 2002 - HP-Nag: Added PAM based user

authentication module. The implementation is available only on Unix

platforms. The PAM module is optional and it can be built by setting

the environment variable PEGASUS_PAM_AUTHENTICATION."

16. (Sushma Fernandes - HP) 15 Apr 2002 - Implemented static methods

Uint64 getDifference(CIMDateTime, CIMDateTime), to get the difference

between two CIMDateTimes and CIMDateTime getCurrentDateTime(), to return

the current date time as CIMDateTime in the CIMDateTime class. Also added

method Boolean isInterval(), to check if the CIMDateTime object is an

interval.

17. (Nitin Upasani - HP) 15 Apr 2002 - Improved Consumer interface with

indications. Now indications can be displayed using sample

DisplayConsumer. To test, create Handler with destination as

localhost:5988/logicalname. Create a file consumer_list.dat in your

PEGASUS_HOME directory and then ass entry as follows:

logicalname = DisplayConsumer

This will help ConsumerTable to load the DisplayConsumer to consume

the indication passed through ExportServer (CIMExportRequestDispathcer).

18. (Yi Zhou - HP) 15 Apr 2002 - Implemented sending message of provider

registration notification to subscription service.

19. (Roger Kumpf - HP) 16 Apr 2002 - Defined an exception hierarchy for

CIMClient API users. All exceptions thrown by CIMClient are now

subclasses of CIMClientException. The CIMClient methods are defined

as throwing CIMClientException, which will allow the actual exceptions

thrown to change without changing the method signatures. It also makes

it more clear to the client application which exceptions need to be

handled.

A new message type, ClientExceptionMessage has been defined as well.

This message is used to communicate client exceptions from the CIM

operation response decoder to the CIMClient. Previously, several

classes of exceptions were being dropped in the decoder. New

CIMClientException subclasses have been defined to model these

exceptions. These changes allow decoding exceptions to be passed

back to the client application. Examples are unparsable HTTP

responses, malformed XML, and mismatched CIM responses (message ID,

message type).

The CIM clients that are linked into the Pegasus build have been

updated to catch CIMClientException instead of CIMException.

20. (KS) 18 Apr 2002 -Incorporated tomof client into the build. Includes

usage and help.

This program outputs mof or xml from repository either as a client

or direct to the repository.

21. (KS) 18 Apr 2002 - Changed all FIXME, etc. in compiler to ATTN with

priorities.

22. (MM) 18 Apr 2002 - Associator provider handling

23. (MM) 18 Apr 2002 - HiRes pegasus_gettimeofday() for Windows needed

for performance statistics.

24. (Roger Kumpf - HP) 18 Apr 2002 - Removed the "match" code in the

String class which had a dependency on the TCL license. Where this

code was being used to match HTTP headers, I replaced the call to

String::matchNoCase() with specific logic to check for the namespace

in an HTTP extension header. For example, if the allowNamespacePrefix

argument is true and the search tag is "Tag", HTTPMessage::lookupHeader

will match "Tag" and "45-Tag", but not "abcTag". This behavior more

closely models the intent of the String match in this case and is

therefore more correct.

25. (Denise Eckstein - HP) 20 Apr 2002 - Added an instance of

PegasusVersion.h to each product component. This was done

to support component level version tracking.

26. (MM) 22 Apr 2002 - Performance Measurement Implementation

27. (Susan Campbell - HP) 22 Apr 2002 - Various enhancements and bug fixes

to the Managed System OS provider. Rolled in the Linux support from

the Linux-specific OS provider and added properties to the HP-UX and

Windows OS providers.

28. (Roger Kumpf - HP) 24 Apr 2002 - Overhauled the configuration property

"unset" functionality. cimconfig now uses modifyInstance with a

property list to specify whether the current or planned value (or both)

are to be updated. It uses a "null" value to indicate that the value

should be unset (reset to default).

29. (Roger Kumpf - HP) 24 Apr 2002 - Restructured the configuration

property owners to remove redundant code.

30. (Warren Otsuka - HP) 26 Apr 2002 - Reimplement wbemexec to use a

new WbemExecClient interface based on HTTPConnection instead of the

obsolete Channel code. Also add SSL option to wbemexec.

31. (Roger Kumpf - HP) 26 Apr 2002 - Added copy constructors to the

CIMMessage subclasses.

32. (Denise Eckstein - HP) 27 Apr 2002 - Fixed several defects

in MOF compiler associated with the handling the initialization

of array values.

33. (KS) 30 April 2002 - Added Namespace Control Provider. Note that it is

not completely tested today and only enumeratenames is guaranteed.

34. (Roger Kumpf - HP) 6 May 2002 - Reworked the String class. Fixed the

places where StrLen() was reading off the end of arrays. Removed the

Cat() functions. Moved Open(), OpenAppend(), and GetLine() functions

to the FileSystem module. Removed the EmptyStringArray() method.

Moved method implementations from header file to source file. Marked

the _CString class for internal use only.

35. (Sushma Fernandes - HP) 9 May 2002 - Updated the Logger to log to

syslog on the HP-UX platform.

36. (Sushma Fernandes - HP) 9 May 2002 - Fixed the method

CIMDateTime::getCurrentDateTime() to return local time instead of UTC.

Updated the CIMDateTime::getDifference() method to compute the difference

between two local times. Also updated the getDifference to compute the

difference between two intervals.

37. (Mary Hinton) 10 May 2002 - Fixed the problem in the new version of

pegasus_gettimeofday(struct timeval *tv)function for the Windows

platform. The new implementation was implemented for higher resolution

for performance statistics. However, it was causing an intermittent

hang in the ThreadPool test on the Windows platform.When (long int)

is changed to (__int64), the tv_usec variable of timeval struct has

the correct value.

38. (Roger Kumpf - HP) 13 May 2002 - To eliminate the possibility of

collisions (and subsequent corruption) when different threads

concurrently update the ArrayRep reference count, I added a Mutex

to the ArrayRep structure. This Mutex gets locked in the inc()

and dec() methods that manage the reference count.

After adding the Mutex, the "mysterious" memory problems seemed to clear

up. This seems like a very good thing. However, note that the addition

of the Mutex adversely affects performance (nearly 2:1). I tried using

an AtomicInt for the reference count, but that seemed to yield even worse

performance on my system.

Anyone should feel free to optimize the performance of the locking in

the ArrayRep structure. Since I believe this locking is required for

proper operation, I've added the Mutex for all platforms. Note that I

had to comment out the assert statements in internal_dq.h to avoid a

circular header file dependency (Array.h->IPC.h->internal_dq.h->

Exception.h->String.h->Array.h).

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

Version 1.08 working towards 1.1 - Started 27 March 2002

TAG: Version_1_08. Note that the tagging was not all simultaneous because

of problems with the CVS repository

1. KS 27 March 2002 - Updaded pegasus version to 1.08. Took snapshot.

Tagged CVS 1_08.

2. KS 2 April 2002 -Add better qualifier testfunctions to cimclass,

qualifierlist, etc. and start to add specific qualifier tests on creates.

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

Version 1.07 working towards 1.1 - Started 4 Feb 2002

Started just before cutover to the new dispatcher, etc.

TAG: VERSION_1_07

1. KS - Updated pegsusversion to 1.07 and tagged file.

2. (Markus Mueller) 05 Feb 2002 - AIX support.

3. (Sushma Fernandes - HP) 13 Feb 2002 Implemented FileSystemPropertyOwner

class to support PEGASUS_HOME dependent properties like Repository

location, Provider location and Consumer location.

The default location for these properties continue to be the same

as before. Added support to the Config Manager to own the

Pegasus Home variable and implemented method (getHomedPath) to

return absolute paths based from Pegasus Home.

For more information look in to the following files:

pegasus/src/Pegasus/Config/ConfigManager.h

pegasus/src/Pegasus/Config/ConfigManager.cpp

pegasus/src/Pegasus/Config/FileSystemPropertyOwner.h

pegasus/src/Pegasus/Config/FileSystemPropertyOwner.cpp

4. KS - 18 Feb 02 Add changes to test for and set the NULL value for CIMValues.

This forces new CIMValues to have a NULL attributes that is only

reset when a value is "set" or copied into them. the XML and MOF

also deliver a NULL value back when the state of the CIMValue is NULL.

There is a remaining addition to put an exception on CIMValue gets when

the NULL attribute is set that we will install later.

5. KS - 19 Feb 2002 Extended testclient slightly and cleaned up numerous bugs.

6. KS - 19 Feb 2002 - Add workpaper in doc/workpaper defining the Pegasus Qualifiers.

Note that this version of the paper still needs work.

7. (Nag Boranna - HP) 20 Feb 2002 - Modified HTTPAcceptor to optionally bind to

loopback host. Modified CIMClient to connect to loopback host when connectLocal()

method is used. Added a new method lookupPort() in System.h to return the system

configured wbem port number. Modified cimuser, cimauth and cimconfig CLI's to use

modified CIMClient connectLocal() interface.

8. (KS- 21 Feb 2002) - Modified Makefile for repository load so located in

schema directory. The one in src/pegasus/compiler/load is deprecated and

will be deleted.

9. KS-21 Feb 2002 - Added new constructor to CIMValue and associated tests

10. RK-20 Feb 2002 - Add Array reference to CIMValue and added tests

11. (Sushma Fernandes - HP, Nag Boranna - HP) 22 Feb 2002 Implemented

checks for privileged user when performing authorization.

Added a configuration property enableRemotePrivilegedUserAccess.

This property needs to be set to true to enable privileged user access

for remote clients.

12. (Roger Kumpf - HP) 22 Feb 2002 - Added type information to extrinsic

method (InvokeMethod) operations. This change involves the addition

of PARAMTYPE attributes to PARAMVALUE and RETURNVALUE tags. This tag

allows the server to determine the type of a parameter value without

having to look up the method definition in the schema. It also allows

the client API to do the same for output parameters as well as return

values.

PROVIDER IMPLICATIONS:

Method providers ARE affected by this change. Previously, all input

parameters to invokeMethod were sent to the provider as String type

regardless of what the client actually specified or how the method

was defined. With this change, providers will now receive input

parameters of the type that was actually specified by the client

application (regardless of how the method was defined in the schema).

However, parameters coming from clients other than the Pegasus client

API may omit the PARAMTYPE attribute. In this case, the operation

processor (currently dispatcher) will find these "typeless" parameters

and convert them to the correct type based on the method definition.

The result is that if the client specifies the parameter type in the

XML encoding (as the Pegasus client API does), the method provider

will receive the type specified by the client; if the client does not

specify the parameter type, the method provider will see the type

specified in the method definition.

CLIENT IMPLICATIONS:

Clients ARE affected by this change. Any output parameters that are

returned from Pegasus (or other CIM servers using the PARAMTYPE

attribute) will now be received by Pegasus clients as the same type

sent by the server. Previously, they would have always been of

String type. In addition, the return value will be received as the

correct type rather than as a String.

Parameters coming from servers other than Pegasus may omit the

PARAMTYPE attribute. In this case, the client will see a

CIMParamValue with type==CIMType::NONE, with a CIMValue of type

String. Similarly, return values coming from other servers that omit

PARAMTYPE will be seen by the client as String type. These return

values will NOT have the CIMType::NONE hint that parameters get,

because they are CIMValues rather than CIMParamValues.

This behavior will remain for the forseeable future (through

Pegasus version 2), as it is not possible to require that other

implementations use the PARAMTYPE attribute.

SIDE EFFECTS:

In the process of implementing this functionality, I discovered

that there was no way to set a CIMValue to be an array of

CIMReferences. This appeared to be an oversight, since method

parameters are permitted to be arrays of CIMReferences. I've

added the necessary functionality to the CIMValue class.

I also found that the CIMParamValue class needed significant

clean-up, which I completed.

SETPROPERTY CHANGES:

A similar problem in SetProperty operations was addressed by

"typing" the specified property value in the operation processor

(currently dispatcher). This is achieved by looking up the

relevant schema to get the property definition, and then converting

the specified value to that property's type.

The SetProperty operation encoding has not changed to accomodate

inclusion of type information that would obviate the need for this

extra processing. However, clients can avoid this overhead by using

ModifyInstance operations (with a property list) instead of SetProperty.

The GetProperty operation also has NOT been updated with type

information. Client applications using the Pegasus client API will

always receive String or reference values when calling GetProperty

against any server (Pegasus or not). Clients that require properties

to be returned as the correct type must use GetInstance (perhaps with

a property list) rather than GetProperty.

13. (Roger Kumpf - HP) 22 Feb 2002 - Reworked the CIMParamValue class.

Instead of being composed of a CIMParameter and a CIMValue, this

class is now composed of a String (parameter name) and a CIMValue.

This change removes the redundancy of having the type, isArray,

and arraySize members in both the CIMParameter and the CIMValue.

The new CIMParamValue definition is more consistent with the XML

encoding of parameter values.

An isTyped member was also added to CIMParamValue to support the

behavior outlined in item 12 above. Clients should use the isTyped()

method to determine whether the output parameters returned from

InvokeMethod operations are of the correct type, or whether they

have defaulted to String type.

14. (KS) 4 March 2002 - Corrections for NULL value and the XML code.

Corrections to compiler for Null values input (parser and valuectory)

15. (Nag Boranna - HP) 04 March 2002 - Modified CIMClient API to accept

username and password as parameters to connect() method, added a new

method diconnect() that closes the open connection with the server

and added code to handle HTTP Basic authentication challenges from

the server.

16 (KS) 4 March 2002 - Correct problem with array constants not picking up

all of the entires in the array. Bugzilla bug # 6.

17. (Yi Zhou - HP) 4 March 2002 - Implemented provider registration manager

to perform efficient lookup of instance provider, method provider, and

indication provider. Also, implemented provider registration instances

operations.

Modified registration provider to use latest provider registration schema.

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.

21. (KS) 7 March 2002 - Correct error in qualifier propagation processing in

qualifierlist.resolve. Temporarily remove the DEFAULT setup on the

Compiler qualifier generation. Add tests for resolve processing.

22. (Roger Kumpf - HP) 8 Mar 2002 - Simplified CIMClient API construction.

Previously, the client application constructed a client API using:

Monitor* monitor = new Monitor;

HTTPConnector* connector;

connector = new HTTPConnector(monitor);

Uint32 timeoutMillis = 60 * 1000; // optional

CIMClient client(monitor, connector, timeoutMillis);

With this change, the client application now looks like:

Uint32 timeoutMillis = 60 * 1000; // optional

CIMClient client(timeoutMillis);

The old style allowed an SSL context to be specified in the HTTPConnector

constructor. It seems that the SSL context is really a property of a

connection rather than of the client API. So instead of adding an SSL

context parameter to the CIMClient constructor, I added it to the CIMClient

connect() method. There are now forms of the connect() method with and

without an SSL context. Similar changes were made in the HTTPConnector

class to allow specification of an SSL context in the connect() method

rather than in the constructor.

NOTE: Client applications are affected and must be updated with this

change. I've already updated all the clients that are checked in and

included in the Pegasus build.

23. (KS) 8 March 2002 - Correct error in compiler that caused length field

of fixed length arrays to be lost.

24. (Jenny Yu - HP) 8 March 2002 - Modified the CIMException class to NOT

include the source filename and line number in the exception message.

However, for anyone who wishes to include such information in the

CIM Exception message, a compile option DEBUG_CIMEXCEPTION can be used

for that purpose.

A couple of changes have been made to the Tracer class:

- CIMException messages can now be put in a trace file using the Tracer.

A new interface has been added to the Tracer to accept a CIMException

as input and writes the exception message in the CIMException to the

trace file. This message will include the source filename and the

line number of the CIMException originator.

Tracer::traceCIMException(traceComponent, traceLevel, cimException);

- Strings can now be traced using the Tracer class:

A new interface has been added to the Tracer to accept a String as

input and writes the String to the trace file.

(ex.)

You can issue the following method call:

Tracer::trace(TRC_CONFIG, Tracer::LEVEL2, "Operation Failed.");

or use the following new macro:

PEG_TRACE_STRING(TRC_CONFIG, Tracer::LEVEL2, "Operation Failed.");

25. (Ramnath Ravindran - Compaq) 11 March 2002 - added IPCTru64.h and modified

several files so that Pegasus could build and run on Tru64 unix. Added

one macro in ConfigUnix and ConfigWindows (PEGASUS_OR_IOS_BINARY) in

the case where std::ios::binary is present with a bitwise OR operator.

This macro only works when the std::ios::binary is NOT the first

operator to be "OR"ed.

26. (Ramnath Ravindran - Compaq) 12 March 2002 - modified more files so that

Pegasus could build and run on Tru64 unix. Finished replacing instances

of ios::binary with the macros PEGASUS_IOS_BINARY and

PEGASUS_OR_IOS_BINARY. Also modified some code that dealt with file

streams. Tru64 does not support the use of the " != " operator on a

fstream object. Instances of such were either modified or an ifdef

block detecting a build on Tru64 was used. Added cstdarg and ctime in

pegasus/src/stdcxx/cwrappers/ directory.

27. (Mary Hinton) 16 March 2002 - fixed the CIMServer so that it could once

again be installed as a Windows service. The repositoryRootPath could

not be found, because the pegasusHome variable was not being set properly

in the Windows service work thread.

28. (Bob Blair by KS) 17 March 2002 - Modified repository so there is both a

local repository (cimmofl) and a client interface repository (cimmof)

executable

29. (KS ) 18 March 2002 - Modified schema makefiles to use the cimomfl respository

executable.

30. (Roger Kumpf - HP) 19 Mar 2002 - Added range checking for Uint* and

Sint* values in XmlReader.cpp. Previously, values that were out of

range were simply truncated to fit the given integer size. An

exception is now thrown when the given string can not be parsed into

an integer of the specified size.

31. (Roger Kumpf - HP) 20 Mar 2002 - Added support for hexadecimal integers

in XmlReader.cpp.

32. (Nag Boranna - HP) 21 March 2002 - Implemented server side Basic

Authentication handling code and cleaned up ATTN's in the authentication

releated files. Implemented a new AuthenticationInfoRep class and modified

the related files. Added more test cases to test the authentication classes.

33. (Ramnath Ravindran - Compaq) 21 March 2002 - replaced instances of "| ios::binary"

with PEGASUS_OR_IOS_BINARY in 3 files: System.cpp, InstanceIndexFile.cpp, and

InstanceDataFile.cpp

34. (KS) 25 March 2002 - Extended qualifier resolution to correctly handle Flavors nad

enabled the scope and flavors testing. Had been pretty much blocked before.

35. (Roger Kumpf - HP) 26 Mar 2002 - Created a class to map CIM operation

request messages to provider API calls. Cleaned up the dispatcher and

added the ability to pass requests to control providers through the

ModuleController. Integrated the ConfigSettingProvider with the

ModuleController and set up the structure for getting the control

providers working. Moved the ConfigSettingProvider from the

Providers tree to the Pegasus tree, since it really is statically

linked into the server.

36. (Roger Kumpf - HP) 27 Mar 2002 - Integrated the UserAuthProvider with

the ModuleController as a control provider. Moved the UserAuthProvider

from the Providers tree to the Pegasus tree.

37. (Roger Kumpf - HP) 27 Mar 2002 - Integrated the

ProviderRegistrationProvider with the ModuleController as a control

provider. Moved the ProviderRegistrationProvider to the Pegasus

ControlProviders directory. Obsoleted and removed the

Server/ConfigurationManager class and files.

38. (KS) 27 march 2002 - Modifications to common functions and the compiler to

extend the processing of class creation and correct the flavors and their

use. This allows flavors to be inherited with rules for override, etc.

-------------------------------------------------------------------

Version 1.06 working towards 1.1 Started 13 December 2001

1. Merged back to Main branch. All general development will be in main branch

in the future with releases in side branches. Special side developments

may temporarily be in side branches.

Changed cimversion to 1.06. We will do 1.1 based on functionality.

2. (Karl) 18 December 2001 - Added new directory repositories where repository

implementations will be kept to separate them from the

repository interface defintion. Initial implementation is genericfile

which is the current file based repository.

Added new build variable RMREPOSITORY which is a generic MAKE command

to remove an existing repository. It simply substitutes for the RMDIRHIER

command at this point but we will make this a generic part of system

in the future.

3. (Roger Kumpf - HP) 18 Dec 2001 - Updated the CIMOperationRequestDecoder

to check that all required parameters for intrinsic methods are

present. If a required parameter is missing, a CIM_ERR_INVALID_PARAMETER

exception is thrown. Also added checks for duplicate parameters in the

intrinsic methods. If a parameter is specified more than once, a

CIM_ERR_INVALID_PARAMETER exception is thrown.

4. (Nag Boranna - HP) 14 Jan 2002 - Created CIMOperationRequestAuthorizer queue

and moved Authorization verification code from CIMOperationRequestDecoder

queue to this new queue. Modified CIMServer.cpp to create

CIMOperationRequestAuthorizer queue only when authorization is enabled.

Also modified CIMRequestMessagesin CIMMessage.h to include userName to make

it available to the CIMOperationRequestDispatcher.

5. (Mary Hinton - Jan 17, 2002) Fixed the problem with the CIMserver when it

runs as a Windows service. The work thread was exiting instead of running

forever. The problem was noticed when the TestClient program and CIMserver

service were both running. The service wasn't accessible to the TestClient

program.

6. (Nitin Upasani - Jan 25, 2002) Operations on CIM_IndicationSubscription,

CIM_IndicationHandlerCIMXML and CIM_IndicationFilter classes will be now processed

in new queue, IndicationService which will get invoked from dispatcher.

CIM_CREATE_INSTANCE_REQUEST_MESSAGE

CIM_MODIFY_INSTANCE_REQUEST_MESSAGE

CIM_DELETE_INSTANCE_REQUEST_MESSAGE

CIM_GET_INSTANCE_REQUEST_MESSAGE

CIM_ENUMERATE_INSTANCES_REQUEST_MESSAGE

CIM_ENUMERATE_INSTANCE_NAMES_REQUEST_MESSAGE

This new service will also take care of processing the indications on receiving

CIM_PROCESS_INDICATION_REQUEST_MESSAGE. This message should come from

IndicationProvider or some other mechanism which is not yet clear.

IndicationService will also receive following messages from PG_ProviderRegistration

when a new IndicationProvider will get registered.

CIM_NOTIFY_PROVIDER_REGISTRATION_REQUEST_MESSAGE

CIM_NOTIFY_PROVIDER_TERMINATION_REQUEST_MESSAGE

I had also defined new Indication Provider APIs, enableIndication, disableIndication

and modifyIndication with more parameters passed and eventually planning to terminate

old APIs (provideIndication, cancelIndication and updateIndication). Also there is a

plan to implement one more call as startIndication and will be done soon.

There are three new test programs in IndicationService directory, which will create

Filter, Indication and Subscription instances using IndicationService.

Also modified sample IndicationProvider code with the new APIs introduced.

39. (Markus Mueller - IBM) 09 Nov 2001 - Added Associator calls to CIMBase

ProviderFacade.cpp; fixed Provider unloading in CIMProviderManager.cpp

40. (Rudy Schuet - Compaq) 12 Nov 2001 - Common module: added the following

files for nsk platform support: TraceFileHandlerNsk.cpp, ThreadNsk.cpp,

TCPChannelNsk.cpp, SystemNsk.cpp, ServiceNsk.cpp, SelectorNsk.cpp,

IPCNsk.cpp, DirNsk.cpp. Most of these files (with the exception of

SystemNsk.cpp) contain stubs. The associated control files

(TraceFileHandler.cpp, Thread.cpp, etc) have been updated to include

nsk platform links.

41. (Roger Kumpf - HP) 14 Nov 2001 - Changed the behavior of the CIMValue

toString() method for CIMValues of String type. The old behavior

returned an XML encoding of the String with special characters

replaced by their UTF-8 equivalents. For example, a CIMValue of a"b

would be returned as a"b. The new behavior just returns the

String value directly with no translation. (Note that

CIMValue.toXml() may still be used to get the XML-encoded value.)

This change was necessary in part to correct the behavior of the

repository. CreateInstance stores the instance name returned by

CIMInstance.getInstanceName(), which is built using calls to

CIMValue.toString(). GetInstance searches for the instance name

without UTF-8 encoding of special characters. For GetInstance to

be successful, CreateInstance must have stored the instance name

in that same form, without special character encoding.

42. (Roger Kumpf - HP) 15 Nov 2001 - Added a toXml(void) method to

the CIMValue class. Eliminated improper use of CIMValue.toString(),

often replacing with CIMValue.get(String&) or CIMValue.toXml().

Also added some error handling in the indication handlers.

43. (Sushma Fernandes - HP) 16 Nov 2001 - Added a function

localObjectPathtoXml(Array<Sint8>& out) to the CIMReference class

to handle local instance path and local classpath. Modified the

CIMOperationRequestDecoder to handle <LOCALCLASSPATHELEMENT ...>.

Changed the CIMOperationRequestEncoder to call the localObjectPathtoXml.

44. (Roger Kumpf - HP) 19 Nov 2001 - Added a CIMNamedInstance class

to hold the argument to ModifyInstance and the return values

from EnumerateInstances. The client and provider APIs need to

be updated to use this class.

45. (Sushma Fernandes - HP) 19 Nov 2001 - Added the cimuser command line

source files. This CLI allows addition, modification, removal and listing

of CIM users. The CLI is not linked to the main makefile as the Provider

functionality is yet to be implemented. Added the function

String getPassword(char* prompt) to the System.h and cpp files.

46. (Nag Boranna - HP) 20 Nov 2001 - Implemented Authentication code on

the server to challenge the unauthorized requests, authenticate

the challenge responses, and verify the subsequent authorized requests.

Implemented authentication mechanism on the Client api to send

responses to the challenges from the server. Current implementation

supports only 'local' authentication mechanism.

47. (Roger Kumpf - HP) 20 Nov 2001 - Commited the following set of changes:

- Changed the return value of EnumerateInstances from Array<CIMInstance>

to Array<CIMNamedInstance>

- Changed the parameter to ModifyInstance from CIMInstance to

CIMNamedInstance

- Added an optional PropertyList parameter to ModifyInstance

- Changed all handling of PropertyList parameters to use the

CIMPropertyList class instead of Array<String>

Each of these changes was required to comply with the DMTF specification.

These changes were made throughout the system except for in the provider

API. For now, the CIMProviderHandle and CIMBaseProviderHandle hide the

differences from providers, so older providers will continue to function.

However, this means that clients can not yet take advantage of the added

functionality.

When the provider API is updated, the following changes will be visible:

- Providers will get a PropertyList parameter to ModifyInstance which

they are required to respect. Providers that can not process the

PropertyList must throw a NOT_SUPPORTED exception whenever the

list is not null. Clients can take advantage of this change by

issuing a ModifyInstance request against a selected set of

properties in an instance, rather than being required to replace

the entire instance.

- Providers will be required to return instance names along with

instances in the EnumerateInstances method. Clients will receive

these instance names, as the standard dictates.

- Providers will receive a CIMPropertyList argument containing the

PropertyList instead of an Array<String>. This change allows

providers to distinguish between an empty list and a null list.

Note that the repository also does not yet handle the PropertyList in

ModifyInstance correctly.

48. (Roger Kumpf - HP) 21 Nov 2001 - I have updated the Provider2 instance

provider API to match the changes made to the EnumerateInstances and

ModifyInstance operations. These changes were made to comply with

the DMTF specification.

The original Provider API has not been updated, and I have no

plans to do so. Providers written to the original API will

continue to function, but they will not have the opportunity

to take advantage of the features that have been added.

The significant changes to the Provider2 API are:

- Providers will get a PropertyList parameter to ModifyInstance which

they are required to respect. Providers that can not process the

PropertyList must throw a NOT_SUPPORTED exception whenever the

list is not null. Clients can take advantage of this change by

issuing a ModifyInstance request against a selected set of

properties in an instance, rather than being required to replace

the entire instance.

- Providers will get an IncludeQualifiers parameter to ModifyInstance

which they are required to respect. If IncludeQualifiers is

false, the qualifiers on the modified instance provided must not

be used to update the instance.

- Providers will be required to return instance names along with

instances in the EnumerateInstances method. Clients will receive

these instance names, as the standard dictates.

The providers that are in the Pegasus build have all been updated.

However, whenever the PropertyList is not null, the providers throw

a NOT_SUPPORTED exception.

49. (Rudy Schuet - Compaq) 25 NOV 2001 - To support the NSK platform,

files Platform_NSK_NONSTOP_NMCPLUS.h and ConfigNsk.h were added to

the Common module. File Config.h was modified to include the NSK

platform and a new option PEGASUS_HAVE_NO_STD that allows compilation

without the standard (std) namespace.

50. (Roger Kumpf - HP) 26 Nov 2001 - Added two new configuration

properties to support alternate behavior of the Pegasus repository:

repositoryIsDefaultInstanceProvider and repositoryProviderName.

Using the first one, the repository can be enabled/disabled as the

default provider for instance (and association) operations. The default

setting is "true", so the default behavior has not been changed. To

disable the repository as the default instance provider, issue the

following command before starting cimserver:

cimconfig -s repositoryIsDefaultInstanceProvider=false -p

The repositoryProviderName configuration property specifies what

provider name is used to explicitly register the repository as a

provider. This is necessary when the repository needs to serve

instances of a class and repositoryIsDefaultInstanceProvider is set

to "false". The default value is "repository". To register the

repository as an instance provider for a class, add a

'Provider("repository")' qualifier to the class definition.

51. (Roger Kumpf - HP) 26 Nov 2001 - Added a new ServiceCIMOMHandle to

pass to providers that act as services. This handle provides

service providers with access to the CIMServer data structures.

52. (Roger Kumpf - HP) 28 Nov 2001 - Implemented ModifyInstance in

the repository so that it respects the IncludeQualifiers and

PropertyList parameters. Updated SetProperty in the repository

so that it uses ModifyInstance correctly. The repository now

supports GetProperty and SetProperty in addition to ModifyInstance.

Implemented GetProperty and SetProperty in the Dispatcher and

Provider2 so that they get translated to GetInstance and

ModifyInstance calls (respectively) in the provider. Providers

written to the Provider2 API that correctly process the new

ModifyInstance parameters will automatically support SetProperty

operations. Note that GetProperty and SetProperty currently only

work for String properties because of an XML encoding limitation.

53. (Nag Boranna - HP, Sushma Fernandes - HP) 30 Nov 2001 - Implemented the

Security components for authentication and authorization.

Authentication and User Management:

cimuser CLI : This CLI is used for addition, modification, removal

and listing of CIM Users. The CIM user password is encrypted and stored

in a file. The password file format is compatible with Apache's htpasswd

generated password file.

cimauth CLI implement the authorization managment functionality by letting

to add/remove/list user authorizations.

User Manager and User Manager Provider components implement the user

management and authorization functionality.

54. (Mike Brasher - BMC) 3 Dec 2001 - Added support for WQL-1. New directory

under src/Pegasus/WQL which contains library and BNF.

55. (Yi Zhou - HP) 03 Dec 2001 - Implemented Pegasus registration provider

which does provider registration, block, unblock, and stop a provider.

It also alert Subscription Service of any provider registration changes.

56. (Rudy Schuet - Compaq) 04 Dec 2001 - Replaced _min macro in String.h

and String.cpp with PEG_min. The _min macro caused problems on the

NSK platform because of a duplicate definition in a standard file.

57. (Carol Ann Krug Graves - HP) 04 Dec 2001 - Implemented Pegasus indication

subscription service provider that serves as the instance provider for the

CIM_IndicationSubscription, CIM_IndicationFilter and CIM_IndicationHandler

classes (from CIM_Events27.mof). The service also takes appropriate action

in response to startup, shutdown of the cimom, termination of a provider,

or change in provider registration.

58. (Jenny Yu - HP) 05 Dec 2001 - Implemented Pegasus Shutdown Service

and the command line interface for shutting down cimom gracefully.

For more information, refer to the CIMOM Shutdown working paper

in pegasus/doc/WorkPapers/CIMOMShutdown.pdf.

59. (Markus Mueller - IBM) 06 Dec 2001 - Implemented SSL support (Linux only).

It consists the new classes SSL_Context, SSLSocket and MP_Socket defined

in TLS.h. HTTPAcceptor and HTTPConnector are extended with an additional

constructor to set a pointer to the server-, resp. client wide SSL_Context

structure. The Socket field in HTTPConnection is substituted with an

MP_Socket pointer, a class that is designed to hide the differences

between Socket and SSLSocket. The MP_Socket (multipurpose socket) class

is defined even in a non-ssl environment.

How to use it in a Server or Client:

1. Just create an SSL_Context once per Server/Client address space

2. Construct every HTTPConnector/Acceptor with a pointer to this

SSL_Context if you want to enable SSL; construct Connectors/Acceptors

without SSL_Context for conventional connections.

The Configuration data was extended with the boolean SSL property, and

cimserver and TestClient now understand the -SSL, resp. -ssl flag.
