32 <h2>Summary</h2>
33 <p>
34 This document details my experiences getting CIM Indications to
35 work with the Pegasus CIMOM. It explains the changes I had to
36 make, the bugs I had to fix, and then makes some design
37 recommendations for integrating Indication support into the Open
38 Group CVS tree.
39 </p>
40 <h3>What Works? </h3>
41 <p>
42 I have Pegasus supporting Indications, subscriptions, and
43 mday 1.1.2.1 handlers. It works really well. All the CIM operations related
44 to indications and subscriptions work. I have tests and test
45 providers.
46 </p>
47
48 <h2>Proposal</h2>
49 <p>
50 Commit the changes outlined in this document to the
51 development (main) branch of the TOG CVS for Pegasus
52 for inclusion in Pegasus release 2.2
53 </p>
54
55 <h2>Terminology</h2>
56 <p>
57 Early feedback on this document has requested clarification of some
58 terms I use later.
59 </p>
60
61 <dl class="enumerated">
62 <dt>Response Handler</dt>
63 <dd>Callback class that receives operation results from Providers.
64 mday 1.1.2.1 This object heirarchy was designed specifically to support
65 asynchronous result delivery from providers, such as Indications.
66 Examples include <code>OperationResponseHandler</code> and
67 <code>EnableIndicationsResponseHandler</code></dd>
68
69 <dt>Indication Consumer Provider</dt>
70 <dd>The C++ object that receives the <code>CIMIndication</code> for
71 handling. This proposal defines a new type of provider that
72 supports the <code>CIMIndicationConsumer</code> interface
73 as defined by Chip Vincent. The <code>CIMIndicationConsumer</code>
74 replaces the <code>IndicationHandler</code> that is currently
75 in the source tree. However, the <code>IndicationHandler</code> can be
76 adjacent (post) to the <code>CIMIndicationConsumer</code> in the
77 indication processing path if required for compatibilty.</dd>
78
79 <dt>Indication Handler</dt>
80 <dd>Existing service in Pegasus for receiving indications and
81 dispatching them to applications. This service has never been
82 supported, and I propose to replace it with the Indication Consumer
83 Provider (above). It can be optionally layered upon the Indication Consumer
84 Provider if required.</dd>
85 mday 1.1.2.1
86 <dt>Export Server</dt>
87 <dd>Pegasus Service that exports <code>CIMIndication</code> instances
88 to other Pegasus instances. I do not refer to the Export Server in this
89 proposal. Its use is compatible with this proposal but optional.</dd>
90
91 <dt>Export Client</dt> <dd>Pegasus Service that listens for and
92 receives <code>CIMIndication</code> instances exported by other
93 Pegasus instances. I do not refer to the Export Client in this
94 proposal. Its use is compatible with this proposal but
95 optional.</dd>

117 <a name="plan_of_attack"><h3>My Plan of Attack</h3></a>
118 <p>
119 There is a ton of rich functionality in the existing Pegasus
120 code base for handling Indications and Subscriptions. The
121 problem is, none of it has been tested due to gating bugs in the
122 Pegasus core.
123 </p>
124 <p>
125 All of the subscription options, policies, and error handling is
126 fantastic code but causes real problems when all you want to do
127 mday 1.1.2.1 is get the underlying mechanisms to work. In fact, the
128 "commercial grade" features of the
129 <code>IndicationService</code> tend to obfuscate the underlying
130 breaks in the Pegasus core that are gating Indication
131 support. So I embarked on a simplification strategy.
132 </p>
133 <div class="notice">
134 <p>
135 Basic Indication Handling should be easy, and robust
136 Indication Handling should be possible. (Yes, I stole this
137 quote from Larry Wall.) To this end I removed some of the
138 functionality from the <code>IndicationService</code>, such as
139 enforcing the schema and implementing policy.
140 </p>
141 <p>
142 I wrote a basic <code>IndicationService</code> and
143 <code>ConsumerProvider</code> that stresses the core of
144 Pegasus and assures the functionality of Indications and
145 Subscriptions.</p>
146 <p>
147 If I need error handling policy and schema enforcement, I
148 mday 1.1.2.1 should be able to create or reactivate the more robust HP
149 Indication Service and substitute it for the simple one. Or I
150 can graft features from the HP service to the simple one. But
151 I shouldn't have to use the untested complex features to debug
152 the inner workings of Pegasus.

157 <h3>What Did I Have to Do to get Indications Working?</h3></a>
158 <p>
159 A little bit of everything. This is an area of Pegasus that has
160 never been completed nore tested. The table below shows the
161 steps I had to take, in order, to get this work completed.

163 <ol class="enumerated">

176 <li>Rewrite the <code>IndicationService</code> to redirect
177 Indications to the <code>ProviderManager</code> (see items 3-5
178 and above).
179 <li>Modify the <code>ProviderManager</code> to treat
180 <code>CIMConsumerProvider</code> modules differently because
181 they are asynchronous by definition.</li>
182 <li>Instantiate the new Providers in a compiled Schema. (I
183 piggy-backed on the existing repository build scripts.)</li>

188 <h3>Where is the source code?</h3></a>
189 <p>
190 mday 1.1.2.1 IBM has, out of necessity, maintained a version of Pegasus that
191 has the original C++ provider interfaces. We did this to support
192 existing providers that we shipped prior to the interface
193 changes this past fall.
194
195 I did the work necessary to support indications on IBM's
196 "classic" snapshot of the source repository. That's where the
197 source code is. Most of the changes were not related to provider
198 interfaces so merging indication support into the Open Group CVS
199 is feasible.
200 </p>
201 <p>
202 Consider this document as a design proposal for indication
203 support; and also as a proposal for checking the source code
204 into the Open Group CVS.
205 </p>
206 <p>
207 I also anticipate making this available as a snapshot on an ftp
208 server.

212 <h3>What is the status of Indication Support in the Open Group
213 CVS?</h3></a>
214 <p>
215 Indications in the Open Group Pegasus 2.x do not work and are
216 not close to working. There are bugs that need to be fixed and
217 design changes that need to be made. They are fairly completely
218 discussed in this document.
219 </p>
220
221 <a name="consumer_provider">
222 <h3>Indication Consumer Provider</h3></a>
223 <p>
224 Chip Vincent and I have long preferred to use Pegasus providers
225 to handle indications. Doing so removes the need for a separate
226 <code>IndicationHandler</code> service. Instead, the handler can
227 reuse all the infrastructure that exists for Providers.
228 </p>
229 <p>
230 Another benefit of using Pegasus providers to handle indications
231 is that developers do not need to learn another service
232 mday 1.1.2.1 interface. The provider interface is sufficient. Also, this
233 means that we (Pegasus developers) do not need to provide
234 separate developer support for handling indications and
235 generating indications.
236 </p>
237 <p>
238 Once a <code>CIMIndicationProvider</code> routine generates a
239 <code>CIMIndication</code>, the modified
240 <code>OperationResponseHandler</code> creates a
241 <code>CIMConsumeIndication</code> message and passes the
242 indication to the <code>ProviderManagerService</code>; the
243 provider manager then finds the "handler," which is really a
244 provider, and calls <code>provider.handleIndication()</code>.
245 </p>
246 <p>
247 There is no need for a separate handler service, which makes
248 error handling and debugging simpler.
249 </p>

252 <h4>Tasks to Support Indication Consumer Providers</h4>
253 mday 1.1.2.1 <p>
254 This was not as simple as activiating the
255 <code>CIMIndicationConsumer</code> code that has been in the
256 source tree for quite some time. I had to ensure that this new
257 type of provider was supported throughout Pegasus.

289 <h4>Indication Response Handler allocated on stack</h4></a>
290 <p>
291 The <code>ProviderManagerService</code> was creating an indication
292 response handler within a local code block and passing that to
293 the Indication Provider with an <code>EnableIndication</code>
294 message. After the ProviderManagerService returned from enabling
295 mday 1.1.2.1 the indication, response handler went out of scope and was
296 destroyed. When the Indication Provider called
297 <code>handler.deliver(indication)</code>, it was using a
298 reference to an object that was destroyed. The result was a
299 core dump.

484 mday 1.1.2.1 <h4>Response Handler Created with Reference to Transient Messages</h4></a>
485 <p>
486 The <code>OperationResponseHandler</code> and derivative classes
487 are constructed with a reference to <code>CIMRequest</code> and
488 <code>CIMResponse</code> messages (i.e., the request/response
489 pair related to the operation). These references were stored and
490 used during the processing of responses. These references
491 pointed to message that were deleted when the thread of
492 execution left the dispatcher. For most CIM operations this is
493 not a problem. However, in the case of indications the responses
494 occur asynchronously. This caused the message references to
495 point to deleted memory. Even this did not manifest a problem until the
496 response handler was destroyed, which occured when the
497 <code>DisableIndications</code> message made its way to the
498 <code>ProviderManagerService</code>.
499 </p>
500 <div class="source">
501 <h5>The fix - copy the messages passed to the response handler.</h5>
502 <p>
503 The lines that implement the fix are <a href="#2_line14">14 and 15</a>
504 and <a href="#2_line102">102 and 103</a>.
505 mday 1.1.2.1 </p>
506 <p>
507 This is a fix that, in my opinion, should be generally applied
508 to all response handlers.

618 <h4>Converting References to CIMInstances</h4></a>
619 <p>
620 References stored in subscriptions and providers were sometimes
621 being handled incorrectly in the <code>IndicationService</code>
622 and the <code>ProviderRegistrationManager</code>, at least when
623 the relationship between class names, class properties, and
624 reference properties was concerned. Reference handling in
625 general could use a library of helper routines. It is too error
626 prone right now to extract a reference and turn it into a
627 <code>CIMInstance</code>.</p>
628 <p>
629 As I was reviewing the <code>IndicationService</code> I noticed
630 that a lot of the "dereferencing" of references was done in
631 mday 1.1.2.1 fairly long code segments that repeated themselves several times
632 with only slight differences. I decided to distill that code
633 into some more compact helper routines. I started on this but
634 haven't finished yet.
635 </p>
636
637 <div class="source">
638 <h5>Partial Fix: helper routines</h5>
639 <div class= "comment">
640 <p>
641 I started working on some helper routines in my re-written
642 <code>IndicationService</code>. Distilling a few routines into
643 lower-level helpers allowed my to jettison a lot of code. As
644 far as I could tell the code in the original Indication
645 Service that I replaced should work just fine but I couldn't
646 get it to. I felt that distilling the code would give me an
647 edge in fixing underlying Pegasus bugs. I still think the bugs
648 were elsewhere (not in the <code>IndicationService</code>)
649 but I can't prove it.
650 </p>
651
652 mday 1.1.2.1 <p>
653 In general I think that Pegasus could benefit greatly from a
654 library of similar, more general, static helper routines to deal
655 with name spaces and the conversion between references and the
656 instances they refer to.
657 </p>
658 <p>
659 I also did some similar rewrites in the
660 <code>ProviderRegistrationManager</code>.

819 <h4>Pegasus Array Template and Virtual Base Classes in Provider Heirarchy</h4></a>
820 mday 1.1.2.1 <p>
821 I think this bug is pretty well understood among Pegasus
822 developers. The problem is in the <code>Array</code> and the way
823 it moves elements that are inserted or deleted from to or from
824 an existing array. The problem only manifests itself when arrays
825 store objects that have a virtual base class, such as
826 <code>Provider</code>.
827 </p>
828 <div class="source">
829 <h5><a href="#array_fix">Fix</a> - only store pointers to dynamically allocated objects
830 in hashtables - when those objects have a virtual base. </h5>
831 <div class="comment">
832 <p>
833 The source of the problem is in lines <a
834 href="#4_line17">17</a> and <a href="#4_line47">47</a>.
835 </p>
836 <p>
837 Classes like <code>Provider</code>, which has a virtual base
838 class, stores a pointer to that virtual base class within
839 its object. When the <code>Array</code> moves the memory
840 upon an insert or delete, it moves the class object but does
841 mday 1.1.2.1 not reinitialize the object's pointer to its virtual
842 base. The object is then corrupt because its vtable has a
843 bad pointer to the object's virtual base class.
844 </p>
845 <p>
846 The problem is related to indications because the
847 <code>IndicationService</code> needs to load Indication
848 providers when an indication is enabled. Typically this
849 happens after Pegasus is up and running for a while and
850 therefore the <code>memmove</code> is more likely to corrupt
851 vtables as described above. The <a href="#array_fix">fix</a>
852 is below.

911 <p>
912 <a name="array_fix">To fix</a> the problem with
913 <code>Array</code> and classes having a virtual base, you must
914 store a pointer to the object instead of a reference. An example
915 of the fix in the <code>ProviderManager</code> is in <a
916 href="#5_line10">lines 10-11</a>, and lines <a
917 href="#5_line33">33</a> and <a href="#5_line45">45</a>.
918 </p>
919 <p>
920 These lines cause pointer to <code>Provider</code> objects
921 to be stored in the <code>ProviderManager</code>'s hash
922 table, instead of the objects themselves. This avoids the
923 problem with vtable corruption but requires management of
924 dynamically allocated objects.

976 <h4>Double Deletes in Redirected Message Pathways</h4></a>
977 <p>
978 There were a couple of double deletes of
979 <code>asyncOpNodes</code> in message paths that were two or
980 three steps removed from the shortest path. These were in
981 code that had never been exersized.

985 <h4>Untested code</h4>
986 <p>
987 The <code>IndicationService</code>, the
988 mday 1.1.2.1 <code>IndicationHandlerService</code>,
989 and the <code>ProviderRegistrationManager</code> each contained
990 code paths that were untested. Really, they were blocked from
991 running successfully due to <i>elusive bugs</i> (see above).
992 </p>
993 <p>
994 In the case of the <code>ProviderRegistrationManager</code>, most of
995 that code was tested so I only needed to step through a few
996 cases.
997 </p>
998 <p>
999 Most of the <code>IndicationService</code> and <i>all</i> of
1000 the <code>IndicationHandler</code> were untested to my knowledge
1001 and they each comprise a lot of code.

1006 <h3>Indication Consumer Support Code</h3></a>

1008 Chip Vincent defined the <code>CIMIndicationConsumer</code>
1009 mday 1.1.2.1 interface during the definition of the original C++ provider
1010 manager. It is not used in the Open Group CVS right now, but I
1011 use it to support Indication handling.

1281 <h3>Provider Registration Manager Modifications</h3></a>
1282 mday 1.1.2.1
1283 <p>
1284 After creating a new type of provider, I needed to modify the
1285 <code>ProviderRegistrationManager</code> to load, find, and
1286 dispatch the new provider type. This was pretty simple. I wrote
1287 some additional routines that are basically copies of what is
1288 already there.

1293 Here is one of the new routines I wrote for the <code>
1294 ProviderRegistrationManager</code>. There are several others.

1413 <h3>Instantiating the Modified Schema and Providers</h3></a>
1414 <p>
1415 This was also pretty simple. I piggybacked off the compilation and
1416 installation scripts that are already part of the project.
1417 </p>
1418 <p>
1419 A couple of items to note in the MOF below. <a
1420 href="#9_line47">Line 47</a> shows a <code>Type 6</code>
1421 provider, which is an Indication Consumer provider. Also, the
1422 Indication provider and the Indication Consumer provider are both
1423 part of the same module.
1424 </p>
1425
1426 <p>
1427 Here is the registration mof:

1431 <p >
1432 You can see that I simplified the <code>PG_Subscription</code> class
1433 in <a href="#9_line53">line 53</a> below. There are no policy attributes,
1434 no attribute list, and no filter.
1435 </p>
1436 <p>
1437 To get things working, I assumed that every subscription
1438 includes all attributes every time it is fired. I assumed that
1439 the subscription was created with valid class references and
1440 that providers were registered correctly.
1441 </p>
1442 <p>
1443 In the schema, however, I left the filter in the
1444 Subscription definition. I just didn't make it a required
1445 attribute. I think it is viable to want to test Indication
1446 delivery without having to have filters defined and working.

1511 <h3>Indication Provider</h3></a>
1512 <p>
1513 mday 1.1.2.1 To test Indications, I modified the provider in
1514 <code>$(PEGASUS_HOME)/src/Providers/sample/ProcessIndicationProvider</code>.
1515 The biggest mod is the <code>_monitor</code> routine, which runs
1516 as an independent thread.
1517 </p>
1518 <h4>Independent Indication Thread</h4>
1519 <p>
1520 Most providers that generate indications will need to have an
1521 independent thread. I chose to start and stop the thread in the
1522 <a href="#10_line17"><code>enableIndications</code></a> and
1523 <a href="#10_line36"><code>disableIndications</code></a>
1524 methods, respectively.

1607 <h4>Delivering the Indication</h4>
1608 <p>
1609 To deliver the indication, the <code>_monitor</code> thread
1610 calls <a href="#11_line45"><code>deliver(CIMInstance)</code></a>
1611 using its response handler.
1612 </p>
1613 <p>
1614 The importance of allocating the response handler on the heap in
1615 the <code>ProviderManagerService</code> and preserving it for the
1616 life of the indication thread is demonstrated pretty clearly in the
1617 code below. It should be obvious that the response handler must
1618 mday 1.1.2.1 not be destroyed after the subscription is enabled.
