CHANGE LOG FOR PEGASUS

Version 1.10 - Started 8 June 2002

Code Freeze in Preperation for V2 Release
From here forward, We are fixing bugs.
TAG: Version_1_10

1. 10 June 2002 (KS) - Add new test function to use command line for
many commands. The command is CLI. Right now it has no documentation.

2. (Ramnath Ravindran - HP) 10 June 2002 - Commented out" #define
PEGASUS_HAVE_TEMPLATE_SPECIALIZATION" in Platform_TRU64_ALPHA_DECCXX.h.

3. (Carol Ann Krug Graves - HP) 17 July 2002 -
Modified test source and Makefiles to make it possible to run the test suite
specifying a location in which all temporary files (e.g. output files,
repository files, etc.) are created. This ability can be useful if you would
like, for example, on a test system, to nfs-mount the pegasus directory
without write access, and run the test suite.

The new functionality uses the PEGASUS_TMP environment variable. The TMP_DIR
variable is set from the PEGASUS_TMP environment variable, and used in the
Makefiles. If PEGASUS_TMP is not set, TMP_DIR defaults to ".", and the
behavior is the same as previously (creates files in the current directory).
Test programs use the value of the PEGASUS_TMP environment variable (or "." if
not set) to construct the path of a file or directory to be created.

When new tests are added that need to create files, directories, repository,
etc., please use the TMP_DIR variable in the Makefile, and the value of the
PEGASUS_TMP environment variable in the test program source file. For examples,
see the current test programs (e.g. pegasus/src/Pegasus/Repository/tests/*).

4. (Roger Kumpf - HP) 30 July 2002 - Changes from the Pegasus API review:

- Updated the CIMName class to a data type class
- Added CIMNamespaceName as a data type class
- Updated the client, provider, and common (CIM*) classes to use CIMName
and CIMNamespaceName in place of String when handing CIM names (class,
property, qualifier, method, and parameter names)
- Changed the CIMClass constructor to take a CIMName for the class name
instead of a CIMObjectPath
- Changed the CIMName::equal method to be non-static

5. (Ramnath Ravindran - HP) 15 August 2002 - Added the Tru64 platform to an existing ifdef in suballoc.cpp to prevent compilation errors.

-----------------------------------------------------------------
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 - Implemented SSL handling in
CIMClient.cpp for local connection and modified the CLIs to not to pass
SSLContext to the client api.

44. (Roger Kumpf - HP) 16 May 2002 - Reworked the Array template so that
each array has its own ArrayRep copy rather than Arrays sharing
ArrayReps and reference counting.

45. (Nag Boranna - HP) 17 May 2002 - Moved SSLContext class out of
TLS files, created SSLContextRep to hide members from the users of
SSLContext. Also included CertificateInfo in SSLContext files and
removed the CertificateInfo files, so that the client SDK can only
need to include SSLContext.h for the client apps to use.

46. (Sushma Fernandes - HP) 17 May 2002 - Fixed the CIMInstanceRep::resolve
method to return the correct class origin. Fixed SecurityPropertyOwner to
disallow passwordFilePath="".

47. (Nag Boranna - HP) 20 May 2002 - Modified CIM Server and Client
API to lookup port number from services. CIM Server uses default port
number (5988 for HTTP or 5989 for HTTPS) if no port number is configured
and no port is specified in the configuration file. CIMClient's connectLocal()
method is modified to try and connect to HTTP port, if failed then try and
connect to HTTPS port.

48. (Sushma Fernandes - HP) 21 May 2002: Fixed a problem in repository related
to rollback failure.

49. (MM) 23 May 2002 - Added ProviderAdapter support
The ProviderAdapterManager loads an additional Adapter library in
case of a non-default interfaceName. This Adapter library has to offer a
factory callback PegasusCreateProviderAdapter() in analogy to the
CIMBaseProvider - an example, the AdapterSkeleton, can be found in
src/Providers/generic/CMPIAdapter/

50. (MM) 23 May 2002 - New AtomicInt implementation using pthread_spinlocks.

51. (Nag Boranna - HP) 23 May 2002 - Added config properties
'enableHttpConnection' and 'enableHttpsConnection'. Renamed
'requireAuthentication' to 'enableAuthentication' and 'requireAuthorization'
to 'enableNamespaceAuthorization'. Removed few ATTN's in Authentication code.

52. (Roger Kumpf - HP) 28 May 2002 - Reworked the Array template so that
the implementation is hidden from clients and providers. This was
accomplished by using explicit instantiation of the array template for
each array type that is supported in the client and provider APIs.
The array template implementation is still available for use within
the Pegasus core, allowing implicit instantiation of additional array
types used internally.

53. KS 28 May 2002 - Added heiarchial subclass search of subclasses to
enumerateinstancenames and enumerateinstances. There is a problem
however with trashing of the requests messages so there is a
flag LIMIT_ENUM_TO_ONE_LEVEL in CIMOperationDispatcher.cpp that
causes it to go through all the motions except to request instances
only for the current level.

54. (Sushma Fernandes - HP) 28 May 2002 - Replaced getenv("PEGASUS_TRACE")
with Tracer calls. Fixed UserAuthProvider and ConfigSettingProvider to
check for user credentials. UserAuthProvider checks whether the user
is a privileged user for all operations. ConfigSettingProvider checks
whether the user is a privileged user only for write operations.

55. (Carol Ann Krug Graves - HP) 30 May 2002 -
Removed the CIMNamedInstance and CIMObjectWithPath classes. The CIMObject
and CIMInstance classes now include a setPath (CIMObjectPath) method.
These changes will affect Clients and Providers. A call to the
CIMNamedInstance constructor with a CIMObjectPath and a CIMInstance should
be replaced with a call to the setPath () method on the CIMInstance,
passing the same CIMObjectPath. A call to the CIMNamedInstance
getInstance () method should be replaced with the CIMInstance, and a call
to the CIMNamedInstance getInstanceName () method should be replaced with a
call to the getPath () method on the CIMInstance. A call to the
CIMObjectWithPath constructor with a CIMObjectPath and a CIMObject, should
be replaced with a call the setPath () method on the CIMObject, passing the
same CIMObjectPath. A call to the CIMObjectWithPath getObject () method
should be replaced with the CIMObject, and a call to the CIMObjectWithPath
getReference () method should be replaced with a call to the CIMObject
getPath () method.

56. (Jenny Yu - HP) 31 May 2002 - Implemented a cimserver_kill() method
to kill the CIMServer process if the CIM Server is still running after
the shutdown timeout has expired during shutdown. The CIMServer process
Id is saved in a file after CIMServer starts up. This file is removed
after CIMServer terminates normally. Only added code for the HPUX
platform.

57. (Jenny Yu - HP) 03 Jun 2002 - Removed all cimserver command line options
except for: -v (version), -h (help), -D (home), -s (shutdown), and
-install and -remove (for Windows only). All other options can be set
using the <configProperty=value> command line syntax.
========================================================================

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.

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

Version 1.1.1 - 3 August 2001 - Development Branch (Work in Progress)
current working dev branch of build

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

1. (Mike Brasher) Fixed bug with XML generation (was not generating
PARAMETER.REFERENCE constructs for references).

2. (Mike Brasher) Reworked server communication into new module scheme.
=======
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.

36. (Sushma Fernandes - HP) Modified tracer to return invalid components
in case of error in setting trace components. Modified the property owner
init and update methods. Submitted the pegasus/mak/Buildmakefile with
cleanbuild, rebuild and trace configuration options.

37. (Yi Zhou - HP) 05 Nov 2001 - Fixed createInstance to return a CIMReference
(instanceName).

38. (Roger Kumpf - HP) 08 Nov 2001 - Implemented encoding/decoding of
GetProperty/SetProperty/EnumerateInstances request/response messages.
Added encoding and decoding of PropertyList parameters on all
relevant intrinsic methods.

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&quot;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 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.

60. (Bapu Patil - HP) Updated makefiles to support HP-UX IA64 bits O.S.

---------------------------------------------------------------------------
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.

Version 0.97.4 - Tag Created for 0.97.4 and snapshot 7 July 2001

1. Deamonizaiton added to CIMServer.cpp by Mike Day. This includes code bothe
for NT and Linux platforms.

2. KS Changed the namespace cimv20 to cimv2 and the default port from 888 to
5988.
NOTE: 5988 is now the officially recognized preferred port for a CIMServer by
the DMTF.

3. KS Corrected some errors found in interoperability testing during the DMTF
Fusion event. THis included a) extended the test for end of HTTP header from
CR/LF/CR/LF to also allow LF/LF. Not strictly legal but widely used. b).
Extended the HTTP message ID to allow for non-numeric message IDs.

4. Broke out RepositoryDeclContext class from Repository/CIMRepository.cpp
and created RepositoryDeclContext.{cpp,h}. This is the first step in
revamping the compiler to work independently of the repository (grb).

5. Created new makefile Compiler/Makefile.grammar and modified
Compiler/Makefile; and added cimmof_tab.{cpp,h} and cimmof_lex.cpp.
Now when you build normally, you will get the committed grammar and parser
files instead of generating your own for a particular platform. This should
prevent back-level lex and yacc implementations from generating troublesome
code. The committed files are generated from flex 2.5.4 and bison 1,28.
(grb)

6. Added Compiler/compilerDeclContext.{cpp,h} and makefile changes.
This change paves the way for upcoming changes that will allow the compiler
to work indepently of the repository. (grb)

7. Extend testclient (clients/testclient) tests and functions. ks 19 June 2001

8. CV added const to CIMOperations modifyInstance, createInstance,
modifyClass,
createClass to protect caller's object.

9. CV added CIMQueryProvider and CIMAssociationProvider to the Provider2
directory. These
interfaces allow very smart providers to perform advances operations.
CIMProviderStub has
been updated to support the new interfaces. Needs testing.

10. Added rpm packaging support and shell script based build process. MM

11. Changed Make so make tests no longer rebuilds repository. To rebuild
repository you make world, make rebuild or make repository. ks

12. Added associators() and associatorNames() operations to CIM repository.
(MEB)

13. More on association implementation (all four operations supported).
Need to handle deletion of associations and protocol stubs still.
Need to test class associations (rather than just instance associations).
Need to handle deleteInstance().
(MEB)

14. slp client code integrated as pegasus-style c++ library. (MDD)

15. (Karl)Update CGI Client to correct number of errors and install
AssociationName
and ReferenceName functions. This included extensive update to the HTML
pages.

16. (Denise E.) Changes to slp client support code for HPUX (

17. (Markus Mueller) Additional changes to support dynamic libraries. Fixed
ProviderTable tests. Fixed build process (slp with PEGASUS_SUPPORTS_DYNLIB).
Made cimserver accept the -D flag to eliminate the need for environment
variables.

18. (Mike Brasher) Added support for Associators(), AssociatorNames(),
References() and ReferenceNames() CIM operations. These only operate
on instances at this time. They will operate on classes soon.

19. (Mike Glantz) Extended and modified dynamic support
changes to (1) work on HP-UX and (2) have all images and libraries
buildable per the value of PEGASUS_SUPPORTS_DYNLIB. The biggest
change is to program.mak and library-unix.mak, removing specific
lists of dynamic library specs and putting them in the Makefile
and libraries.mak files that build the actual targets (lots of
these now have DYNAMIC_LIBRARIES defined).

20. (Karl) added basic Queue function to common (based on array) and added
tests for stack and queue.

Version 0.97.3 - Released 5 June 2001

1. (KS)OptionManager (CPP and H), Logger (CPP and H), Handler (CPP and H),
CIMServer (both)
Functions added include:
a. Enable trace to log file.
b. Add option so that you can trace to console or trace to logfile (-l
is
trace to log, -t is trace to console).
c. add parameter in optionsrow for help message and enable the capture
of these messages in Options class. Also added help print that
prints these things out. However, format not to beautiful.
d. Eliminate a couple of messages coming from __Namespace provider.
e. Extend the Clients\testclient so he does tests on Namespace.
2. (KS)Extended Log to show time, severity.

3. (KS)Added getCurrentASCIITime functions to System.x

4. (KS)Extended options on CIMServer including 1. option to determine where
logs
are put

5. (KS)Added TestClient that executes a series of tests against a server.
This is a preliminary version.

6. (KS)Corrected problem with acceptor.bind where failure was being lost. Now
throws CannotBind exception.

7. (KS)Added logger entry to XMLParser for errors. NOTE: At this point it may
not
print out all of the message. At the least it prints out the error message
and components of the message causing the problem.

8. (KS)Added clean option to server but temprarily disabled.

9. (KS)Fixed problem where logs were not created unless logs directory already
existed.

10. (Mike Brasher) Added "Test" prefix to all test program names.

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

Version 0.97.2

1. Extend HP UX port to correctly load Dynamic Load Libraries.
2. Extend Formatter for Boolean and Uint32 types.
3. Change CIM Server to use Trace (-t) flag. This also changed
Handler.h to work off of flag.
4. Minor corrections to __Namespace Provider.
5. Extend tests for Formatter, String, and other modules.
6. Correct errors in documentation.
7. New working papers (provider interface).
8. Add Providerreg.exe tool.
9. Add trace output for messages sent from the Server.

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

23 May 2001 Version 0.97.1 Tags as version_0_971

1. Add PEG_NOT_FOUND symbol to replace Uint32(-1) in any of the object
find functions. Note: This symbol is defined in config.h. (ks).

2. Port To HP UX. This required a number of changes particularly in the area
of dynamic lib loaading.

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

21 May 2001 Version 0.97 - Tagged as version_0_97

1. Added methods in CIMClass, CIMInstance, for existance of properties,
qualifiers, methods.
2. Add methods in CIMClass, CIMInstance to remove properties, qualifier,
methods.
3. Added CIMmethod and CIMProperty in CIMMethod to text for existance of
qualifiers and to
remove qualifiers.
4. Ported to AIX. NOTE: This port was done using an earlier version of the AIX
compiler. It probably imposed more limitations than would be required with
the current compiler. This version of the port produces an excessively large
common module due to template bloat. That problem will be fixed in a future
change to the port. Also there are a log of duplicate symbol warnings generate
by the AIC compiler but these cause no problems. The port has been tested
with the complete unit test and client/server test successfully.

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

23 May 2001

1. Ported to HPUX

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

29 May 2001

1. Implemented CIMRepository::setProperty() and CIMRepository::getProperty().
