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.
