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).

39. (Roger Kumpf - HP) 13 May 2002 - Removed operator int() methods from

all CIM* classes. These methods had been causing a number of difficult

to find defects, including the use of the wrong versions of the methods

in Memory.h by the Array template (leading to major memory leaks).

In general, it is dangerous to define a casting operator method that

loses so much information, because the compiler will apply the cast

at will in an effort to match types. I've replaced all instances of

the int cast operator with isNull() methods.

40. (Nag Boranna - HP) 14 May 2002 - HP-Nag: Added SSL Certificate verification

code in TLS.cpp, created a new class CertificateInfo to pass certificate

information to the client's call back function. Modified CIMServer.cpp and

the Command lines that are using SSLContext to pass a call back function.

Fixed few display messages in CIMConfigCommand.cpp to show meaningfule

messages when CIM server is not running.

41. (Roger Kumpf - HP) 15 May 2002 - Moved CIM*::toXml() methods to

XmlWriter::append*Element(). Moved CIM*::print() methods to

XmlWriter::print*Element(). Putting this function in XmlWriter

instead of the CIM* classes keeps those internal methods out of

the published client and provider APIs.

42. (Roger Kumpf - HP) 15 May 2002 - Moved CIM*::toMof() methods to

a new MofWriter class as MofWriter::append*Element(). Moved

CIM*::printMof() methods to MofWriter::print*Element().

43. (Nag Boranna - HP) 16 May 2002 - HP-Nag: Implemented SSL handling in

CIMClient.cpp for local connection and modified the CLIs to not to pass

SSLContext to the client api.

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

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.

Line 235

Line 510

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.
