4. The changes to WQLCIMOperationRequestDispatcher and CQL... for handling

pull not completed so we feed the responses back to the EnmerationContext

queues

3. Lots of minor TODOs, diagnostics, etc. still in the code

this a separate bug. See bug 9819 for the changes to cover this.

of queue when converting (avoids the second move). This would mean

extending the output writers to allow the count field to be supplied

so they would only create output for up to the count supplied.

OpenEnumerateInstanceNames covered).

9. Could clean up the CIMOperationRequestDecoder.cpp rejectCIMException

Low priority because most of this except exact XML covered in other

tests. note that we can only add very limited tests since a) no

way to test multiple opertions in sequence(i.e. open/pull) and

cannot be sure how many responses will come back in all cases even

for open.

10. Could clean up the CIMOperationRequestDecoder.cpp rejectCIMException

further since there is some overlap. That is low priority.

timeout thread) and a place where not mutuxed, primarily the

timeout thread.

1 May 2014

1. Cleanup of code and variable names.

2. Removed namespace variable from EnumerationContext. It was never used.

3. Added test for max number of open enumerations. Right now it is fixed

and set about 100. Note that this is tied to the size of hash table

so that there is a issue with more dynamic setting of max and the

hash table size.

4. Removed several unused functions.

5. Found one possible issue causing thread conflict but not the core one

yet.

30 April

1. Added exception response to dispatcher for Limits exceeded on

CreateEnumerationContext. Returns Exceeded server limits CIMException.

2. Fixed possible deadlock where we were not unlocking EnumerationContext

under error condition

27 April - mergeout to head of tree

1. Mergeout of the code to the head of tree. Documented that mergeout in

the bug

27 April 2014

1. Clean up in a number of areas, mostly just code without changing

functionality.

2. Modified CIMMessage.h slightly to clarify names of the pull intermediate

messages (the common open and pull response);

3. Removed a number of diagnostics from CIMResponseData

4. Added new function to ResponseStressTestProvider to be able to terminate

output after a defined number of objects with a CIMException.

5. Removed a number of other TODOs

6. Corrected a couple of errors in the server message bundle.

7. Modified ResponseEncoder to only output the error for pull errors.

It was errounously outputting the EndOfSequence, EnumerationContext and

the error. This way, only the error is sent which is spec.

8. Removed number of TODOs and cleaned up a couple of others.

9. Added static tests for OpenEnumerateInstanceNames.

10. Modified a number of the temporary diagnostics to be permanent by

changing them to PEGASUS_DEBUG_ASSERTs

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.

1. Reorganized 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
