<h2>Functionality of This Release</h2>

Pegasus overall status by release is defined by  a

<a href="http://www.openpegasus.org/page.tpl?ggid=799">Feature Status WEB Page</a>

that is available on the OpenPegasus web site .  That

web page shows the Pegasus users and developers

the status of the various features found in Pegasus using a simple color coded

key (white, red, yellow, green).  Pegasus 2.5.1 is a minor release, extending Pegasus 2.5.0 in selected

areas primarily for bug fixes.  However, there were some signification

changes in the feature status for selected functions in 2.5.1 (moving selected

functions closer to production-capable status).The following paragraphs list the functionality in this release.   In many cases these features  and interfaces

are conditionally compiled with special environment variables.

provides more detailed information on how to enable

functionality that is conditionally compiled in this release.

NOTE: For current information and history on the status of each feature,

please access the

OpenPegasus Feature Status WEB Page</a>.  Please see

the Feature status page for the quality/status of each feature because not all

of the features listed below are production ready.

<h3>CIM Server Functionality</h3>

<h4>CIM Operations over HTTP support</h4>

<ol>

<li>Class Operations (getClass, deleteClass, modifyClass,

enumerateClass, enumerateClassNames)</li>

<li>Qualifier Operations (getQualifier, setQualifier,

deleteQualifier) </li>

<li>Instance Operations (getInstance, deleteInstance, modifyInstance,

enumerateInstance, enumerateInstanceNames, getProperty,

setProperty)</li>

<li>Association Operations (references, referencenames,

associators, associatornames)</li>

<li>Methods Operations (invokeMethod)</li>

<li>Query operation - Support for ExecQuery was added in 2.4 with

WQL as query language and is defined in PEP 119. This feature is

considered at alpha quality because it has only been contributor

tested.  Additional tests have been added in 2.5 for ExecQuery. Pegasus

today does not support the ExecuteQuery operation defined as the Query

operation for CQL.

<h4>Query Language</h4>

Pegasus includes the  WQL  query language which is implemented and

used for filters and in version 2.4 for execQuery.

CQL Stage 1 has been added for Pegasus 2.5.  PEPs 138, 193, 205

NOTE: OpenPegasus releases are categorized as follows:

combine to describe the CQL  functionality supported.

<ul>

<h4>Object Normalization</h4>

Normalizer code slowed performance. These issues are now addressed by

compatibility,

moving the Object Normalizer from the Dispatcher to the Response

Handler (or equivalent) and optimizing the existing implementation. The

move allows errors to be reported to the provider at the point of

delivery and ensures that only a single copy is made to preserve the

CIMOM/provider boundary.

<h4>Embedded Object Support</h4>

Pegasus 2.5 provides embedded object support. The proposed solution

is restricted to the following:<ul>

<li>The only representation for embedded objects supported by this

PEP is CIM-XML (i.e. id does not support MOF encoded objects). </li>

<li>CIMObject is implemented as a new CIMValue type. This type will be used

internally to represent embedded objects. When externalized (via

CIM-XML) these objects will be converted to strings representing valid

INSTANCE or CLASS elements, in accordance with the CIM Infrastructure

Specification.  Embedded instances will also carry the

EmbeddedObject attribute with

the value "object", as specified by CR Interop-00217.001.

</li>

<li>3rd number changes (2.12.0 to 2.12.1) - Revision(also called point

release) release and only includes bug fixes.</li>

Status WEB Page</a>.

<h3>Information on Interop namespace name (root/PG_InterOp) for

OpenPegasus 2.12

</h3>

Prior to version 2.12 OpenPegasus used an OpenPegasus internal variable

to define "root/PG_InterOp" as the name for the OpenPegasus namespace

with no defined way to change this variable.  Note that an

unsupported method involving editing one file and rebuilding OpenPegasus

was defined as a workaround in the <a href="%20https://wiki.opengroup.org/pegasus-wiki/doku.php?id=faq:openpegasus_build_and_installing">OpenPegasus

wiki faq</a>s.

However, since the definition of a standard name for this namespace in

DMTF and SNIA specifications ("interop" or "root/interop" with "interop"

being the preferred alternative) the use of  "root/PG_InterOp" has

become an issue.

Effective OpenPegasus 2.12.0 a new build variable has been

defined  (PEGASUS_INTEROP_NAMESPACE) which allows an OpenPegasus

builder to define an alternate name for the Interop namespace to either

"interop" or "root/interop" (ex. PEGASUS_INTEROP_NAMESPACE =

interop).  Once this build variable is defined and OpenPegasus

compiled, the actual name of the interop namespace is what was defined

in this varaible and all components of OpenPegasus use this as the

interop namespace name include the complete OpenPegasus test

suite.  The only name for the interop namespace will be the name

defined through this build variable.

However, today OpenPegasus is committed to the single namespace defined

at build "(root/PG_InterOp", "interop", or "root/interop"). However, a

number of OpenPegasus  installations are committed to the

"root/PG_InterOp" name and must maintain their repositories through

updates of OpenPegasus. While we are working on this issue today (which

means that a running version of OpenPegasus must accept both the and new

names and not confuse clients, listeners or providers that would use

either name) the OpenPegasus team did not complete that work for this

release. See bug <a href="http://bugzilla.openpegasus.org/show_bug.cgi?id=9250">9250</a>

for more information about possible solutions and our progress on a

solution.

NOTE: If you redefine the interop namespace name with

PEGASUS_INTEROP_NAMESPACE clients using the "root/PG_InterOp" namespace

will not connect with the updated version of OpenPegasus.

must support IPv6 or you will get a build failure (missing header

files), a run-time bind() failure, or possibly some other failure. This

applies to both the CIM Server and Listener components. For more

information on IPv6 support for your specific platform, refer to the

documentation for that platform.

All OpenPegasus externals that support either a hostname or an IP

address as input have been updated to allow an IPv6 address to be

specified. If the required input is just an IP address (eg. no optional

or required port number), then the IPv6 address must be specified

without brackets. For example, the OpenPegasus osinfo client (which

returns information about the OS running on a host system) takes

separate host and port options. In this case a host with an

IPv6-configured network interface would be specified as:

<div style="margin-left: 40px; color: rgb(153, 51, 153); font-family: monospace;"><big><font

color="#000000">osinfo -h 3ffe:1:2:1 -p 5988</big></div>

But the cimcli command, which takes an optional "location" option

including an optional port number, requires the IPv6 address to be

delimited with brackets, for example:

<div style="margin-left: 40px; font-family: monospace;"><big>cimcli ns -l

[3ffe:1:2:1]</big></div>

or

<div style="margin-left: 40px;"><big>cimcli

<h4>SLP Discovery</h4>

SLP support is included but is conditionally compiled in or out on

a platform basis. <a href="http://www.openpegasus.org/pp/uploads/40/8502/PEP200_RecommendedReleaseOptions.htm">

PEP 237</a> describes the  environment variable (PEGASUS_ENABLE_SLP) to

enable or disable this code.  Effective with Pegasus 2.5.1, support has

been added for the use of OpenSLP as the Service Agent (SA) in addition to the

internal to the Service Agent.  This is controlled through an additional

environment variable (PEGASUS_HAS_OPENSLP)  Once compiled, SLP

support is enabled with the slp configuration parameter (slp=true). SLP

support includes an SLP service agent in the Pegasus CIM sever (either the

internal agent or OpenSLP)  and

generates SLP advertisements compatible with the DMTF slp template

specification. The SLP support also includes  extensions to the

CIM Client libraries to execute SLP User Agent requests and analyze the

results (note that these interfaces are not yet part of the Pegasus

public SDK).

Note: Pegasus on Windows is built with SLP support on by default.

<h4>Indication Handlers</h4>

<h5>System Log Indication Handler

</h5>

The SysLog Indication Handler is a new

for 2.5

type of Indication Handler which allows CIM Indications to be delivered

to the system syslog file. It has following features:

Each syslog file entry has a tag 'CIM Indication' to distinguish

an entry made by Syslog Indication Handler.

If a subscriber includes PerceivedSeverity property in the SELECT

list of the filter condition for the indication, the PerceivedSeverity

will be mapped to syslog error severity. Otherwise, syslog error

severity 'LOG_INFO' is used.

for 2.5

type of Indication Handler that allows CIM Indications to be delivered

to a specified e-mail address.   See

<h4>Pegasus Provider Interfaces</h4>

Pegasus is designed to support multiple Provider Managers to allow

multiple provider interfaces to the CIMOM.  The two default

provider managers are the Pegasus C++ Interface and Common

Manageability Programming Interface (CMPI) Interface.

<h5>C++ Provider Interface</h5>

This is the original

interface defined for OpenPegasus Providers.  It provides an interface

for both operations and indications. Many of the sample and test providers are

written to this interface.  This interface includes a callback into the

CIMOM (CIMOMHandle).

<h5>CMPI C interface Provider Manager<o:p></o:p></h5>

To check whether your current running kernel supports IPv6, take a look

short automated test looks like:

result of a project by the IBM SBLIM team (see 

http://sblim.sourceforge.net) and is written to the Common

Manageability Programming Interface, which is an OpenGroup standard.

The CMPI

specification is available at:

http://www.opengroup.org/bookstore/catalog/c051.htm. This provides a

standardized C level interface for creating providers that can be

registered with the Pegasus CIM Server in the same manner as the

current C++ providers.  The

ability for CMPI providers to do user authorization is now available in

Pegasus 2.5.1.

Information on writing providers with the CMPI interface is available

in the specification today (see above) and in the following documents

(http://sblim.sourceforge.net/whitepaper.html and

http://sblim.sourceforge.net/presentations.html) and readme.cmpi in the

Pegasus source root directory.

NOTE: See the Feature status page

for exact status of the CMPI provider manager for different Pegasus

platforms.

<h4>Server Statistics Provider

</h4>

CIM Server statistics, based on the DMTF 'CIM_StatisticalData' class,

are implemented in this release. The statistics gathering is compiled

by default but it is disabled through a property in the singleton

CIM_ObjectManager class. It may be enabled or disabled by performing a

ModifyInstance operation on the 'CIM_ObjectManager instance

in the 'PG_InterOp' namespace to set the GatherStatisticalData property

to 'true' or 'false'. This property setting is persistent across CIM

Server restarts. A statistics display test tool, cimperf, is available

from the Pegasus CVS repository. <h4>SLP Provider</h4>

This provider acts as the definer of

SLP information for SLP registration and also controls the Pegasus SLP

Service Agent. It is treated as a normal provider rather than a control

provider because it does not use internal functions of the CIMOM to

generate any of its information today. (conditionally compiled today)

<h2>Pegasus Indication Listeners</h2>

The generic components for a CIM Listener and a

listener API are operational.  This includes the functions for

HTTP, XML indication input and response, and consumers of indications.

This code can be used to define a separate listener package and is used

as an indication listener in the Pegasus server.

Pegasus includes 3 separate Indication Listeners.

<h4>Testing  OpenPegasus IPv6 support</h4>

<h3>Embedded CIMListener</h3>

IPv6 loopback address (::1) if PEGASUS_ENABLE_IPV6=true.

<h3>Standalone Static CIMListener</h3>

This is a standalone listener that combines the functions

of listener and consumer into a single element.

<h3>Standalone Dynamic Listener</h3>

Pegasus 2.5

includes a new standalone dynamic listener that is separate

from the current standalone CIMListener and the ExportServer listener

in the CIM server.

The use model that this listener fits is the following:

<ul>

<li> The listener may be packaged as

part of the CIMOM or it may be packaged independently as part of

another application. </li>

<li> Consumers

are developed independently of the listener and may be shipped with the

listener or added to an installed listener at a future time. </li>

</ul>

This

dynamic listener provides a solution for the above use model. It

is essentially a lightweight, pluggable listener that

provides a small set of management features. The DynamicListener can be

run inside a daemon or a service. It is easily configurable and

bypasses traditional registration procedures.  See

<a href="http://www.openpegasus.org/pp/protected/upreviews/20/1303/PEP195_CIMListenerEnhancementsv1_6.htm" style="color: blue; text-decoration: underline;">PEP 195</a>  for

details.

</blockquote>

<h3>CIM_Schema</h3>

The default CIM_Schema loaded with this

release is

the DMTF CIM 2.9, final release.  In addition, Pegasus includes

a number of

local classes defined for Pegasus.  These are defined in the pegasus/Schemas

directory.   There are also a

number of older schema available in the CVS.  Further, the CIM 2.10 and CIM

2.11 schemas are available in the CVS repository and the Pegasus is compatible

with these Schemas.

The mechanism to install other schemas than the default is defined

in the mak/config.mak

NOTE: The CIM 2.5 schema is

maintained in the

CVS repository because it remains the basis for parts of the Pegasus

test

environment.

<h3>Pegasus Interface APIs</h3>

Details of the Pegasus public interfaces for this release are listed

in PEP 209

available from the web site(<a href="http://www.openpegasus.org/pp/uploads/40/Administrator/My%20Documents/processes/www.openpegasus.org">www.openpegasus.org</a>).

That document is the authorative source for the list

of publicly supported Pegasus APIs.   The Client and Provider API were

originally frozen at the Pegasus version 2.1 release. The interfaces in the

release of Pegasus 2.1 are forward compatible to this release. Well-behaved

clients and providers compiled to the Pegasus 2.1 or 2.2 interfaces should be

compatible with this release without compilation.  There have been

extensions and new interfaces added for this release.

  The Pegasus public

interfaces includes the following major functions

<li class="MsoNormal" style="color: black;">Client APIs<o:p></o:p></li>

<li class="MsoNormal" style="color: black;">Provider APIs<o:p></o:p></li>

<li class="MsoNormal" style="color: black;">CIM Object and System

function APIs</li>

</ol>

In addition, there are other client interfaces which are not today

in the public SDK including:

<li class="MsoNormal" style="color: rgb(0, 0, 0);">CIM Listener APIs</li>

<li class="MsoNormal">CIM Listener

is a component that can be used to consume indications without a

dependency on the Pegasus CIMOM. In environments where no CIMOM is

running or a physical separation between the indication listener and

the CIMOM is desired, CIM Listener fits the bill. Still, there are

several enhancements that are necessary to make CIM Listener scalable. Enhancements were deemed significant

enough to propose a new listener that builds off CIMListener's

basic capabilities, yet allows the existing CIMListener to remain the

same.</li>

<ul>

<li>New CIM Listener now provides selective

indication delivery.

</li>

<li>New CIM Listener

keeps all consumer libraries in memory for the duration of its

execution.

</li>

<li>New CIM Listener

is now pluggable.</li>

<li>New CIM Listener

now provides reliable indication delivery.</li>

</ul>

<li class="MsoNormal" style="color: black;">SLP

Client (User Agent) APIs which are extensions to the Client APIs</li>

</ol>

<o:p> </o:p>

The APIs are

documented in

their respective header files and  in HTML documentation based on

the information

in the header files extracted with the doc++ tool will be available on

the

OpenPegasus web site.

WMI Mapper

The WBEM to WMI Mapper provides a way

to access

WMI data from Windows platform systems. It converts incoming XML/CIM

requests

to Microsoft WMI requests, executes the requests, converts the results

XML/CIM and returns the results to the client. WMI Mapper

receives an HTTP message containing the XML/CIM request. It decodes the

XML

message and extracts from the HTTP message header the user credentials

provided

on the connection (username and password). The WMI Mapper

authenticates these credentials, verifying if the provided credentials

have

access to the desired WMI data. This is done because the WMI Mapper runs as a service, logged on using an

account with

administrative rights (which has all access to WMI data). Because of

this, the

WMI Mapper impersonates the user

credentials provided

on the HTTP message to ensure that the calling user has rights to

browse WMI

data. Hence, ALL requests made to the WMI Mapper

MUST

contain user credentials.

<h2><a name="Supported Platforms">Supported

<h2><a name="Conformance with DMTF Specifications"></a>DMTF/SNIS SMI

Profiles Supported</h2>

Today OpenPegasus includes support for several DMTF profiles including

the ones defined below:

<ol>

<li>DMTF ProfileRegistration Version 1.0.0</li>

<li>DMTF Indications 1.1.0. Since this is effectively the same as the

SNIA SMI Indication profile it also supports this profile. This

profile is enabled by compiling OpenPegasus with the buld variable

PEGASUS_ENABLE_DMTF_INDICATION_SUPPORT.

</li>

<li>SNIA Profile Registration 1.0.0</li>

<li>SNIA Server 1.1.0 & 1.2.0

</li>

</ol>

<h2><a name="Conformance with DMTF Specifications">Conformance Exceptions

to DMTF Specifications</a></h2>

It is a major goal of the OpenPegasus project to both drive and utilize

the DMTF CIM/WBEM specifications.  However, today there are a

number of known differences.  As of this release, some of the

differences include the following:

<ol>

<li>Provider Registration - Pegasus supports registration through

a set of Pegasus Provider registration classes rather than support the

DMTF defined Provider Qualifier. Pegasus will not support this

qualifier in the future. See the readme for more information on

provider registration.  This is not a deviation from the

specifications but is a different method of registration than many CIM

Servers and means that the the provider qualifier is unused in

Pegasus.</li>

<li>Lifecycle Indications -Today Pegasus supports process

indications and lifecycle indications when defined specifically by

providers. Pegasus does not support lifecycle indications if they are

not defined by the provider or for changes to CIM Classes.

For more

information see the Pegasus CVS file:<a name="comtag_137">

pegasus/src/Unsupported/LifecycleIndicationProvider/README.LifecycleIndications.htm</a><font

size="2">.</li>

<li>

IncludeQualifiers

option

on Instance Operations

- The DMTF specifications have deprecated the use of qualifiers on

instance operations with the 1.2 CIM Operations Specification and

stated specifically that the client should NOT depend on the

includeQualifiers parameter of the CIM/XML instance operations

returning qualifiers.  Some CIM Client implementations expect

instances returned from the CIM Server to include the qualifiers

defined in the class definition (such as KEY qualifiers on

properties).   Pegasus today expects the

provider to complete the qualifiers on instances in accordance with

the specification and generally the interpretation is that Pegasus

applies class level qualifiers when the includeInstance parameter is

supplied on instance operations.  However, Pegasus today is

inconsistent in the return of qualifiers so that the user should NOT

depend on Pegasus accurately honoring the includeQualifier parameter

for instance operations.  In the future it is expected that

Pegasus will deprecate the use of qualifiers on instance operations

completely.  When Pegasus uses object normalization, the

normalizer does apply qualifiers to returned instances if the

includeQualifiers operation parameter is set.

</li>

<li>LocalOnly option on instance Operations - With the 1.1

version of Specification for CIM Operations over HTTP, the definition

of the LocalOnly parameter for the GetInstance and Enumerate Instances

operations was modified. This change was incorrect, resulted in

reduced functionality and introduced a number of backward

compatibility issues. As a result of issues introduced by this change,

we strongly recommend that CIM Clients set LocalOnly = false and do

not rely on the use of this parameter to filter the set of set of

properties returned. See Appendix C of this specification for more

information.</li>

<li>

MultiRequest Operations - Pegasus does not

support the DMTF defined MultiRequest Operation option.

</li>

<li>

MOF Compiler namespace pragma - The

Pegasus compiler does not support the namespace pragma.

</li>

<li>CIMOperation Trailer - Pegasus implements chunking based on

the DSP0200 1.2.0 preliminary spec. including the operation trailer

defined in that specification Refer to bug <a href="http://cvs.opengroup.org/bugzilla/show_bug.cgi?id=6760">6760</a>

for more details. This trailer was completely removed from the DSP0200

1.2 final specification as a non-compatible change so that if chunking

is used Pegasus is returning a noncompliant response to enumerate type

requests. </li>

<li>Whitespace in XML value Element

- Pegasus trims the leading and trailing whitespace from XML value

elements that are of the Type String.  This behavior is

documented in Pegasus bug <a href="http://bugzilla.openpegasus.org/show_bug.cgi?id=8773">8773</a>

and there is a patch available for users.  However, since the

change is considered a change to behavior this will not be patched

until pegasus does a major version update. NOTE: There are some

documented bugs in Pegasus such as this that the OpenPegasus team

feels cannot be incorporated into the code until a major version

update.  These bugs are documented with the Bugzilla tag <big style="font-weight: bold;"><samp>"3.0_TARGET".</samp></big></li>

<li>modifyInstance operation behavior

in the Pegasus repository does not match the DMTF specification.

Under some conditions (ex. if no propertyList is supplied) it modifies

all properties rather than just the properties supplied with the

request thereby Nulling out existing values. See bug <a href="http://bugzilla.openpegasus.org/show_bug.cgi?id=8752">8752</a>

for more information.</li>

<li>OpenPegasus Interop Namespace - The default interop namespace

name in OpenPegasus is "root/PG_Interop".  In versions of

OpenPegasus prior to 2.12.0 this could be changed during build by

modifying a string definition in the code. Effective version 2.12

this  has become a build option with the build configuraton

environment variable PEGASUS_INTEROP_NAMESPACE = <name for this

namespace> however, the default if built without this change is

still "root/PG_InterOp"

</li>

<li>OpenPegasus WSMAN protocol on windows does not handle NaN, INF,

or -INF (bug  <a href="http://bugzilla.openpegasus.org/show_bug.cgi?id=8836">8836</a>)

- If requests or responses include properties or parameters with

floating point property types (Real32 or Real64) with the special

states NaN, INF, or -INF on a Windows platform, the input is not

accepted because these special strings are not understood by the

decoder on Windows.</li>

<li>OpenPegasus outputs Nan, INF, -INF special values for Real32 and

Real64 property and Parameter types for the CIM/XML protocol -

(bug <a href="http://bugzilla.openpegasus.org/show_bug.cgi?id=9392">9392</a>).

Today the DMTF Specification DSP0201 allows only numeric information

in the format definition for this type and does not all the special

strings Nan, etc. However, OpenPegasus actually outputs the special

strings if  that is what is defined in the internal values. 

OpenPegasus does not allow these special Strings on input however,</li>

<li>OpenPegasus does not handle covered properties - (bug <a href="http://bugzilla.openpegasus.org/show_bug.cgi?id=3571">3571</a>)

Covered properties (properties which have the same name in a

superclass and subclass without overridding the property in the

superclass) are not allowed in OpenPegasus. While the requirement for

this functionality was added to DSP0004 subsequent to version 2.4, the

general agreement is that the requirement itself is not supportable

and particularly not with the existing OpenPegasus APIs. 

Further, the requirement is expected to be removed in the future (i.e

CIM 3.0).

<h2><a name="Conformance with DMTF Specifications">Conformance with

DMTF Specifications</a></h2>

It is a major goal

of the OpenPegasus project to both drive and utilize the DMTF CIM/WBEM

specifications.  However, today there are a number of known

differences. 

As of this release, some of the differences include the following:

<ol>

<li>Provider Registration - Pegasus supports registration

through a set of Pegasus Provider registration classes rather than

support the DMTF defined Provider Qualifier. Pegasus will not support

this qualifier in the future. See the readme for more information on

provider registration.</li>

<li> Indications -Today Pegasus supports process

indications but does not

include any specific support for lifecycle indications.</li>

<li>

IncludeQualifiers

option on Instance Operations

The DMTF specifications are unclear regarding the inclusion of

qualifiers on

CIM instances.  Some CIM Client implementations expect instances

returned

from the CIM Server to include the qualifiers defined in the class

definition (such as KEY qualifiers on properties).   Pegasus

today expects the provider to complete the qualifiers on instances in

accordance with the specification and generally the interpretation is

that Pegasus applies class level qualifiers when the includeInstance

parameter is supplied on instance operations.  However, Pegasus

today is inconsistent in the return of qualifiers so that the user

should NOT depend on Pegasus accurately honoring the includeQualifier

parameter for instance operations.  In the future it is expected

that Pegasus will deprecate the use of qualifiers on instance

operations completely.

</li>

<li>LocalOnly option on instance

Operations - With the 1.1 version of Specification for CIM

Operations over HTTP, the definition of the LocalOnly parameter for the

GetInstance and EnumerateInstances operations was modified. This change

was incorrect, resulted in reduced functionality and introduced a

<h2><a name="Changes in This Release">Changes in This Release</a></h2>

The development and release of each version of Pegasus is defined

and

controlled through Pegasus PEP documents.  PEP 180 is the

controlling document  for Pegasus 2.5.0 and PEP 239 is the controlling

document for this release. These PEPs list the original set of changes proposed and the

status of

each of those changes. Note that not all of the originally defined

functionality was completed for this release.

In general, the areas of development for release 2.5.0 were:

Addition of CQL

stage 1 support

</li>

Refactoring of

Object Normalizer function to improve performance.

</li>

Out of Process

Provider user level request.

</li>

support.

</li>

enhancements

</li>

Completion of

AutoPtr enhancements.

</li>

Certificate

management and user-based certificate authentication

</li>

Completion of HTTP

chunking. Pegasus

now supports HTTP V1.1 transfer encoding otherwise known as chunking .<a href="http://www.openpegasus.org/pp/uploads/40/5097/PEP140_ChunkedEncoding_4.3.html">

PEP 140</a> describes the implementation details.

<li class="MsoNormal" style="color: black;">Email Indication handler.</li>

<li class="MsoNormal" style="color: black;">Port to OpenVMS.</li>

</ol>

For release 2.5.1, a number of additional changes were made( See PEP 239 for

more details):.

<li>Significant performance improvements ( better than 10 to 1 for operations

and 3 to 1 for indications). (bug 4225)</li>

<li>Improved support for the several platforms (Solaris, MacOS, HardHat Linux)</li>

<li>Modified Makefile targets for easier usage.</li>

<li>Extended and reorganized unit and end-end tests.</li>

<li>Completed implementation of statistics gathering for operations.</li>

<li>Further integrated CMPI and added additional tests.</li>

<li>Consolidate some of the compile-time variables. Largely this meant moving

from separate variables for DISABLE and ENABLE to a single variable where the

value representes the state.</li>

<li>Corrected error where Pegasus could not maintain general whitespace in

strings (bug 4624).</li>

<li>SLP extended to allow optional use of OpenSLP as the Service Agent (SA) in place of

the Pegasus internal SA.</li>

<li>Changes to align OpenPegasus and Red Hat RPM packaging and configuration

options.</li>

<li>Additonal testing and integration of the  JMPI provider manager.</li>
