Notes on Specific
OpenPegasus Functionality Changes
This section documents specific issues that the OpenPegasus team feels are
important to OpenPegasus users with the current release (and possibly
Add new RunTime Variables to control trace file size and Rotation(OpenPegasus
As of OpenPegasus 2.13.0, two new runtime variables have been added:
* traceFileSizeKBytes - Defines the size of the
tracefile in kilobytes. The trace file will be rolled once its size
exceeds the specified size.
* numberOfTraceFiles - Specifies the number of the tracefiles
for rolling where the default is 3.
Using GCC 4.7 Compiler on Linux OS (OpenPegasus 2.13.0)
As of 2.13.0, OpenPegasus has been updated to replace the custom atomic
operations with GCC built-in atomic operations if GCC version 4.7 or
greater is used as the compiler. It is recommended that if possible
this version of the GCC compiler be used since the change provides
significant performance improvements.
OpenPegasus and OpenSLP V 2.0 (OpenPegasus 2.13.0)
As of 2.13.0, OpenPegasus slp fully supports IPV6 and has been
tested with OpenSLP 2.0 (Recently released by OpenSlp.org
While testing OpenPegasus with OpenSLP 2.0 the OpenPegasus team found two
issues with this version of OpenSLP. The patches documented below
allow this version of OpenSLP to work with OpenPegasus
1) SLPReg used TCP connection previously, but it now uses UDP. Therefore,
a BUFFER_OVERFLOW exception occurs. This is because UDP cannot
handle attribute size greater than network MTU size. In such cases,
according to the specification, OpenSLP should automatically switch to
TCP. Since this has not been implemented in OpenSlp 2.0, the
workaround used by OpenPegasus to force use of TCP may be found at http://sourceforge.net/p/openslp/bugs/139/
2) On Windows, slpd service fails to start when IPV6 is enabled and throws
the error message "Error 1067: the process terminated unexpectedly". More
details and the fix for this issue are in the bug http://sourceforge.net/p/openslp/bugs/140/
Interop namespace name (OpenPegasus 2.13.0)
Effective with the release of OpenPegasus 2.13 the "interop"
namespace support for existing or
older repositories which used
"root/PG_InterOp" has been added via a new option in the "reupgrade"
utility. Users with existing repositories may use this option to migrate
the repository from "root/PG_InterOp" to
"interop" namespace. See bug
For this to work, the build option "PEGASUS_INTEROP_NAMESPACE" has
set to "interop". Only then will the "-i" option in repupgrade be enabled.
Once the repository is upgraded with "-i" , the namespace
will cease to exsist. Clients using "root/PG_InterOp" must now use
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 OpenPegasus
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. Support for forward-compatibility is a fundamental design
principle for the OpenPegasus project. As a community, our goal is for
well-behaved OpenPegasus providers or clients, using only the externally
defined OpenPegasus interface, to continue to work with each version
upgrade of OpenPegasus.
Effective OpenPegasus 2.12.0 a new build variable was 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. This is the logical
approach for implementations starting a new repository.
In order to supexport PEGASUS_CLIENT_TRACE=keyword:keywordport users with
existing repositories, in 2.13.0, migration of existing repositories
was integrated into the "repupgrade" utility to allow existing OpenPegasus
environments to smoothly move the server from use of the old name
for the interop namespace "root/PG_InterOp" to
the prefered name "interop".
If the interop namespace
name is redefined with PEGASUS_INTEROP_NAMESPACE clients using the
"root/PG_InterOp" namespace will not connect with the updated version of
OpenPegasus. The OpenPegasus team searched for a solution to the issue
supporting the old and new name at the same time and concluded that there
were so many issues that it could not effectively be done.
Configure Script to Control OpenPegasus Builds (OpenPegasus
OpenPegasus is moving from the use of environment variables to a configure
script to control build. This is both to make it easier to define
the build variables, etc. and to be more compatibile with the Linux/Unix
standard build environment. However, because OpenPegasus must build
on a number of platforms that do not support the full Linux/Unix
configuration tool set, this is an OpenPegasus defined configure
script. The first very experimental version is part of OpenPegasu
2.13.0 but this version has a number of limitations (see the OpenPegasus
Bugzilla) and will be expanded in the next versions of OpenPegasus.
The goal is to replace the setting of most of the OpenPegasus build
environment variable with options in the pegasus/configure script where
those options are comatible with the Linux standard for defining configure
options and those options control the entire build process including placement
of output and choice of build options.
Tracing Client Requests and Responses(OpenPegasus2.13.0)
long contained a hidden build controlled function to allow tracing at
the client through an environment variable
(PEGASUS_CLIENT_TRACE_ON). In 2.13.0 this was a) make a permanent
part of of the environment (Bug 9564) and the calling convention
to make it simpler to use.
The original format for the
environment variable was:
so that the normal setup for a console output trace would be
Information on IPV6 Support and OpenPegasus(PEP 291)(OpenPegasus
This functionality was incorporated in OpenPegasus 2.7.0 but
it was felt that the information below was worth repeating in subsequent
IPv6 Support for OpenPegasus is documented in
The IPv6 support in OpenPegasus is controlled by the PEGASUS_ENABLE_IPV6
build variable. The default for this variable is "true"; setting this to
'false' before building OpenPegasus will disable the IPv6 support.
The following subsections provide some information on IPv6 support for the
Linux and Windows platforms. Note that in the 2.6.1 release there is no
automatic run-time detection of IPv6 support on a platform by OpenPegasus.
If you build with PEGASUS_ENABLE_IPV6=true, your platform 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 eitcompilerher 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:
osinfo -h 3ffe:1:2:1 -p 5988
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:
cimcli ns -l
ns -l [3ffe:1:2:1]:5989
For more information on specifying IPv6 addresses, refer to IETF
2373 - IP Version 6 Addressing Architecture
RFC 2732 - Format for Literal IPv6 Addresses in URL's
IPv6 on Linux
Modern Linux distributions already contain IPv6-ready kernels, the IPv6
capability is generally compiled as a module, but it's possible that this
module is not loaded automatically on startup.
you shouldn't use
kernel series 2.2.x, because it's not IPv6-up-to-date anymore. Also the
IPv6 support in series 2.4.x is no longer improved according to
definitions in latest RFCs. It's recommend to use series 2.6.x now.
To check whether your current running kernel supports IPv6, take a look
into your /proc filesystem. The entry /proc/net/if_inet6 must exist. A
short automated test looks like:
test -f /proc/net/if_inet6 && echo "Running
kernel is IPv6 ready"
For more iSchema version default update to CIM 2.36nformation on enabling
IPv6 in the Linux kernel and configuring network interfaces, refer to The Linux
Documentation Project's IPv6 HOWTO
: There is currently an
open issue with RedHat to address a problem that is seen intermittently on
RHEL5 and SLES10 systems. This problem is described in
and manifests itself as an intermittent IPv6
socket failure. You should be aware that OpenPegasus with IPv6 enabled may
be significantly impacted in these environments.
IPv6 on Windows
Microsoft provides supported IPv6 implementations for Windows Server 2003,
Windows XP with Service Pack 1 (SP1), Windows XP with Service Pack 2
(SP2), and Windows CE .NET 4.1 and later.
On Windows XP, you can use the ipv6.exe
tool to install, uninstall, and query your IPv6 configuration. For
Windows Vista and Windows Server 2008 support an integrated IPv4 and IPv6
implementation known as the Next Generation TCP/IP stack. Note that the
OpenPegasus IPv6 support has not yet been tested on Windows Vista or
Windows Server 2008.
For more information on installing, configuring, and using IPv6 on Windows
platforms, refer to the document IPv6 for Microsoft Windows: Frequently Asked Questions
Testing OpenPegasus IPv6 support
As part of the OpenPegasus automated tests, the TestClient, g11ntest, and
IndicationStressTest test clients were modified to run tests using the
IPv6 loopback address (::1) if PEGASUS_ENABLE_IPV6=true.
You can also perform manual tests using the IPv6 loopback or a real
IPv6-configured network interface. For example, using the IPv6 loopback on
a system with OpenPegasus running on the WBEM standard http port of 5988:
osinfo -h ::1
Support for forward-compatibility is a fundamental design principle for
the OpenPegasus project. As a community, our goal is for well-behaved
OpenPegasus providers or clients, using only the externally defined
OpenPegasus interface, to continue to work with a minor version upgrade of
OpenPegasus. However, there are certain classes of errors (e.g.,
non-compliance with a standard that significantly affects
interoperability) that may require the community to make potentially
incompatible changes. The following table contains a list of defects/fixes
that MAY impact, even well-behaved, OpenPegasus providers or clients when
upgrading to this OpenPegasus release.
with OpenPegasus 2.11.0 the requirement for providers (CMPI and C++) to
filter properties from instances has been relieved. The server will do
the filtering at the protocol adapter level. To avoid a negative impact
on performance the CIMInstance::filter() and
CMPIInstanceFT.setPropertyFilter() functions have been changed to a
NOP. This may be a change in behavior for provider relying in some
unknown way on the instance being filtered through these functions. To
allow users to actually filter properties from an instance in a
provider, a new function (CIMInstance::filterInstance()) will actually
filter properties from an instance exactly as the CIMInstance::filter()
did in previous versions of Pegasus. This is not required since the
CIMServer will do the filtering but allows the provider to prefilter
properties if it so desires, in particular where properties might be
very large or there would be a significant number of properties.
|NOTE: This bug
fixed in OpenPegasus 2.13.0. Reregistering of an
indication provider requires that the cimserver be restarted
to send the enableIndication request to the providers. This issue
has existed starting with OpenPegasus 2.10 to version 2.12.
If the cimserver is not restarted the indication will not be
enabled for the reregistered provider.
OpenPegasus Relationship to CIM/WBEM Standards

specifications The following table defines the level of the DMTF
specifications to which this version of Pegasus aims to conform today.

Today OpenPegasus includes support for several DMTF profiles including:
- DMTF ProfileRegistration Version DSP 1033, Version 1.0.0
- DMTF Indications DSP 1054, Version 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
- SNIA Profile Registration 1.0.0
- SNIA Server 1.1.0 & 1.2.0
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:
- 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 really a deviation from the specifications since there is no
specification or profile for provider registration today but is a
different method of registration than many CIM Servers and means that
the the provider qualifier is unused in Pegasus.
- Lifecycle Indications -Today Pegasus supports process
iPegasusndications 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.
information see the Pegasus CVS file:
on Instance Operations
- The DMTF specifications have deprecated the use of qualifiers on
instance operations with the 1.2 CIM Operations Over HTTP Specification (DSP0200) 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.
- 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
- MultiRequest CIM/XML Option
- Pegasus does not support the DMTF defined MultiRequest
Operation option (See DSP0200).
- MOF Namespace Pragma -The
Pegasus compiler does not support the namespace pragma defined in DSP
0004. Namespaces for the OpenPegasus repository are defined through
arguments for the MOF Compiler
- 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 6760
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
- 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 8773
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 "3.0_TARGET".
- 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 8752
for more information.
- 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 2.12.0
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". Effective with OpenPegasus 2.13.0 the reupgrade utility has been extended to allow existing repositories to be converted from the use of "root/PG_Interop" to "interop" (See discussion above). The default in the CVS source code is still "root/PG_InterOp".
- OpenPegasus WSMAN protocol on windows does not handle NaN, INF,
or -INFHowever, t (bug 8836)
- 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.
- OpenPegasus outputs Nan, INF, -INF special values for Real32 and
Real64 property and Parameter types for the CIM/XML protocol -
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,
- OpenPegasus does not handle covered properties - (bug 3571)
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
Each OpenPegasus release lists as 'active' platforms those
hardware/software platforms that have recognized ports for the Pegasus
code base including a maintainer for the platform that will be willing to
regularly document issues and/or fix defects as the Pegasus code base is
changed. Pegasus may be operable on other platforms (ex. Windows 98)
but without a group to provide the role of test and maintenance, correct
operation of Pegasus cannot be assured. In all cases,
including the active platforms, it is the responsibility of the entity
that packages and/or compiles OpenPegasus for shipment or deployment, to
read, and actively monitor the Pegasus Bugzilla database for a list of
relevant defects that affect their platform. The platforms
that are considered ported are shown in the two tables below. The
first table represents platform for which testing is done on a regular
basis and reported to the Pegasus Nightly Build Test WEB Page. Those
platforms which have been ported but do not have test results that are
current at the time of the release are reported in the second table.

The OpenPegasus Bugzilla database documents defects found in Pegasus
and is available through the following link: OpenPegasus
. Effective with the start of the
OpenPegasus 2.6 work, ALL changes to the OpenPegasus CVS tree are
documented through bugs. Therefore all source code changes to OpenPegasus
are documented through bugs providing a complete history of changes and
the reasons for those changes. Bugs reports are filed not only for
bugs and their corresponding fixes but also as part of the process of
committing new code representing the work on PEPs done for OpenPegasus 2.6
and all subsequent versions. Therefore, a search of the OpenPegasus
Bugzilla base for bugs with the tag for a particular version (ex. 2.6.0_APPROVED
etc) will yield all changes to the Pegasus CVS tree for that OpenPegasus

The OpenPegasus project is controlled largely through the CVS repository
and a set of documents (PEPs) that serve both as the definition and review
mechanism for new and modified Pegasus functionality and for the
definition and documentation of releases.
The following documentation defines the characteristics of this Pegasus
release. The documents are available in the OpenPegasus CVS
- OpenPegasus Release Definition/Status - (See Wiki Section OpenPegasus
Release Status) - A
section in the Pegasus wiki is used throughout the development of
this version as the control point for functionality that will go
into the release and points to all of the PEPs that represent the
Pegasus functionality changes for this version of Pegasus.
