|
6. Clean up code in Dispatcher. Want to at least reduce the code for the |
|
Open Operations to a set of templates so we know that the code is the |
|
same for all operations. Most of the common code for the enum, assoc, |
|
ref operations and their corresponding open/pull operations is now in a |
|
set of template functions so that it is largely common code. Used the |
|
templates where there is common code but not the same CIMMessage. However, |
|
we should be able to do some of it with common functions (i.e. not templates) |
|
by adding a layer to CIMMessage hiearchy and reduce code size. The |
|
pull is a single template for both pullInstances and pullInstancePaths. |
|
However, we might be able to reduce this to a single function by adding |
|
a new level to CIMMessage.h (CommonPullResponse) |

d. Find issue that is causing occasional failures under load. It |
|
is probably a threading issue between the 3 possible threads |
|
that use the EnumerationContext (request thread, provider thread, |
|
timeout thread) and a place where not mutuxed, primarily the |
|
timeout thread. |
|
|
|
22 April 2014 |
|
1. Clean up some messages. |
|
2. Still trying to find issue that randomly keeps messages in timeout |
|
queue long after they have been closed and returned. |
|
3. Fixed memory loss error. |
|
4. Added zero reject for OperationTimeout because that effectively disables |
|
the whole timeout mechanism so that enumerations could be started, never |
|
completed by the client and would just hang around in memory. That |
|
would be a significant DDOS attack (start very large enum with no |
|
timeout) and never do pulls after open. |
|
|
|
21 April 2014 |
|
1. Reorganizzed code in CIMOperationRequestDecoder.cpp ...Iparam classes. |
|
Cleaned up the rejectCIMException code. |
|
2. Cleanup some issues in the EnumerationContextTimeout Thread. |
|
3. Fixed issue in pullop where it was using zero as default for default |
|
operation timeout where it should have been NULL, the DMTF specified |
|
default. |
|
4. Enabled the test to reject 0 as operation timeout on a request and but |
|
controled by a #define in CIMOperationRequestDispatcher.cpp |
|
5. Added test for excessive new OperationContext entries in table. |
|
|
|
18 April 2014 |
|
1. Internationalize remaining messages in CIMOperationRequestDecoder.cpp and |
|
clean up the decoders for some of the messages so they use the |
|
...Iparam classes. Note that we did not clean up all of the old message |
|
decoders, just the new ones and we did not clean up the Count message |
|
since it is deprecated. TODO clean these up so the decoder is really |
|
consistent. |
|
2. Enabled the EnumerationContext Timer and removed code for alternate |
|
non-thread solution. |
|
|
|
17 April 2014 |
|
1. Reorganized the lock/unlock for handling the EnumerationContext because |
|
there were thread windows (i.e. using the context after it was released |
|
by other thread). |
|
2. Modified code for the InteroperationTimerThread and deleted old code that |
|
allowed this whole thread to by bypassed. |
|
3. Internationalized a number of CIMOperationRequestDispatcher CIMException |
|
response messages. |
|
4. Fixed stress tests in Client/tests/pullop that were getting timeout. The |
|
issue was not the pull code but that fact that the idle client timeout |
|
appears to be measureing to the end of the operation and the operation |
|
was taking more than 40 seconds which is the default timeout. The idle |
|
timeout takes no account of the fact that chunks are being regularly |
|
delivered. |
|
5. Several minor code changes. |
|
NOTE: At this point the code passes extensive tests of the pull operations |
|
both in OOP and none OOP mode (but with lots of diagnostics that may |
|
be affecting timing). |
|
|
|
10 April 2014 |
|
1. Fix issues causing failure with repeated pull operations. |
|
2. Consolidate some of the CIMOperationRequestDispatcher.cpp template code |
|

MergeOut of head of tree. |

|
7 April 2014 |
|
1. Permanently fixed issue with getting correct number of objects on response. |
|
This was introduced when did a temp fix to the OOP processing, in particular |
|
removed the condition variable wait in the CIMOperationDispatcher handle |
|
functions for opens and pulls. This moved the functionality to kick off |
|
open and pull responses to the provider threads if there are not enough |
|
objects when the handle is processed. Also added a variable to allow us to |
|
test with either a) responses are required to satisfy the original |
|
request size or) b, responses are required only to return some objects. |
|
We will add statistics to see which of these works best. |
|
2. Modified WsmProcessor EnumerationContext class since the name conflicts |
|
with the pull Operation EnumerationContext class. |
|
3. Created a new intermediate level of CIMMessage, the CIMPullResponseData |
|
Message so that all of the open and Pull responses can use common code |
|
since there are only two variables (endOfSequence and EnumerationContext) |
|
and they are common across all the open and pull responses. |
|
4. Removed a number of diagnostics. |
|
5. Cleaned up the Dispcatcher so that the open and pulls have common response |
|
code and that code can be used from the dispatcher handle functions and |
|
the provider response functions. |
|
|
|
31 March 2014 - Checkin |
|
1. Fixed issues in OOP processing of pull operations, in particular |
|
issues with cimxml output format when processed through the |
|
*InternalXmlEncoder functions. |
|
2. Clean up some of the internalXml functionality |
|
3. Found issues causing timeout with a particular provider. The issue |
|
is that the dispatcher and monitor end up using the same thread so the |
|
condition variable in the dispatcher thread stops the monitor. Turned |
|
off the conditionVariable in getCache for the moment which means that |
|
we get number of responses for open... with 0 objects before the |
|
providers can begin to respond. This is only for test. |
|
4. Added some statistics for enumerations and display the statistics |
|
when we close the server (same as cache statistics) |
|
|
|

|
|
|
18 November 2013 |
|
1. Cleanup of a bunch of minor errors and completion of all of the code for |
|
the openQueryInstances except for the PullInstances in Dispatcher and |
|
the aggregator function. |
|
2. OpenqueryInstances added to cimcli. |
|
|
|
13 October 2013 CVS branch update. |
|
1. Integrated bug 9786 into the branch. Note that we need to test the |
|
generated statistics. |
|
2. Mergeout executed to update to head of tree as of 8:00 am 13 October 2013. |
|
3. Cleaned up several errors in OOP processing. Note that there is at least |
|
one issue left when we to a pull on ManagedElement in at least one of the |
|
namespaces. |
|
4. Cleaned up some of the outstanding diagnostic code |
|
5. Generally passes all tests except for one test of pullop where it is trying |
|
to pull enum instances CIM_ManagedElement from a particular namespace. |
|
|
|
NOTE: I did not make comments here for changes in October despite the fact |
|
that I did 2 mergouts, number of fixes, and a mergein. |
