NOTES On working with task branch.

Merge out Process

To keep our TASK branch in sync with the current head of tree we need

to do a regular merge out. the TaskMakefile contains the makefile

procedures to do this efficiently. NOTE: Following these procedures is

important in that you are merging out new material each time you do

the merge out. If you were just to repeatedly merge out, you would be

merging previously merged changes a second time causing a real mess.

Start with new directory and put TaskMakefile above pegasus (needed so you

have this file for the initial operations.

make -f TaskMakefile branch_merge_out BNAME=PEP317-pullop ## takes a long time

This checks out current head, merges it into task branch and sets tags

for the mergeout. Note that at the end of this step this work is

part of the TASK... branch.

NOW check for conflicts, errors, etc. that resulted from the merge.

Look for conflict flags, compare the results (I use linux merge as a

good graphic compare tool) and build and test. When you are satisfied

that the merge out is clean, you can commit the results to the TASK...

branch

To commit the work to this into Task branch

make -f mak/TaskMakefile branch_merge_out_commit BNAME=PEP317-pullop

or manually commit and finish as follows

cvs commit

make -f mak/TaskMakefile branch_merge_out_finish BNAME=PEP317-pullop

## This last step is important since it cleans up temporary tags to prepare

you for the next checkout

COMPARE TASKBRANCH WITH HEAD

In a new pegasus work space do same as above for merge out.

make -f TaskMakefile BNAME=PEP317-pullop

This produces a result which is all of the head merged into the branch.

A diff of this is all the new changes to the head of tree that you will

include into the merge.

TODO list:

1. Binary operation from OOP. Need to add counter to binary

protocol to be able to count objects in response. Generates

warnings in things like messageserializer and does not work with

OOP right now.

OOP right now. Corrected by converting to XML.

2. OpenExecQuery - Code is incorrect in that it used InstancesWithPath

2. OpenExecQuery - Code is incorrect in that it does not include the

where the spec is instances with no path. Need new function to wrap

return from the exec query function to the aggregator yet.

Alternate is to put flag on InstancesWith Path to say no path

3. Code for Pull part of OpenQueryInstancesRequest a) should be part of

the common CIMOperationRequestDispatcher execCommon code.

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.

4. External runtime variables. Decide this as part of PEP. The variables

ones to consider are:

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

a. System maxObjectCount. Setting some maximum size on what a pull

client can request (i.e. the maximum size of the maxObjectCount on

Open... and pull operations.

b. Pull interoperationTimeout (max times between operations). This is

the maximum number of seconds on the operationTimeout parameter of the

Open operations

c. Maximum size of the responseCache before it starts backing up

responses to the providers.

5. Decision on EnumerationContext timeout (separate thread or just

checks during other operations). Can we, in fact really keep the

enumeration context table and queue under control without monitoring

Line 34

b. We should protect against providers that no not every finish delivering

or take to long between deliveries. This does not exist in Pegasus

today

6. Clean up code in Dispatcher. The associators code is still real mess

6. Consider moving some of the code in dispatcher from templates to common

and the pull code is in a template. The Pull code is good now but

functions which would mean adding intermediate classes in CIMMessage but

must be duplicated. Look at creating new CIMMessage CIMPullResponseMessage

would reduce code size.

so that we can have common code. Everything is the same except what

goes into the CIMResponseData so it is logical to have completely

common processing

7. Extension to avoid double move of objects in CIMResponseData (one

into enumerationContext queue and second to new cimResponseData for

response. Want to avoid second move by extending Open/Pull response

messages to include count and CIMResponse data to count objects out

of queue when converting (avoids the second move). Big issue here

with binary data since need to extend format to count it.

8. Still using templates, etc. in code in the Dispatcher. This is for

sometimes.

21 November 2013

1. Mergeout from head of tree to 21 November 2013.

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.

30 September 2013 - CVS Update

Mergeout head of tree up to 29 September 2013.

29 September 2013. CVS update.

1. Modified calls to statisticalData.cpp to a) directly call with request

type, b) incorporate the open, pull, etc. messages. However, since these

are not part of the CIM class, we must do something special with them.

See bug 9785 for full solution to this issue.

2. Corrected OOP interface to enable new flag to indicate internal operations

and set host, etc.

3. Add code to CQLOperationsDispatcher and WQLOperationDispatcher to clean

up CIMResponseDataCounter after filtering.

4. Modified ProviderAgent to set Host info for some pull operations.

5. Added new flag to CIMBinMsgSerializer and Deserializer.

17 September 2013 CVS update (Actually two different updates over 3 days)

1. Clean up some issues in CIMMessage.h and CIMMessage.cpp

2. Extend OpenExecQuery to WQL and CQL processors but return not complete

3. Remove memory leak in EnumerationContext and EnumerationContextTable

handling.

4. Created template functions for much of the pull operations.

5. Reversed order of queryLanguage and query (and changed names to match

execQuery) in client and server. Note that these are the execQuery

WQL and CQL filters and NOT FQL filters.

6. Some code cleanup in dispatcher

7. Today, passes all tests in pullop but issue in alltests. For some reason

not finding CIMObjectManager instance. Also, leaves enumeration contexts

if client terminates since cleanup thread not operating.

8. XML from OOP not correctly processed.

14 September 2013 CVS update

Merged out up to 25 August. Cleaned up all operations and standardized code.

At this point the non pull operations code is in a set of templates but the

pull is not yet.

Fixed a significant number of problems so that it appears that the operations

except for OpenExecQuery run stably, at least with the pullop test program.

Note that there is a problem in that the Interop control provider is not

returning its singleton wbemserver object for some reason. Causes a test

failure

Fixed for 16 June CVS Update

1. Cleaned up the enumerationContext and Table release functions and tested

to confirm that we do not lose memory in either normal sequences or

sequences that close early. Cleaned up pullop and added more tests

Taged Before: PREAUG25UPDATE and after POSTAUG25UPDATE

Fixed for 9 June CVS update

1. Cleaned up code for OpenQueryInstances. Note that this is incomplete.

Issues - KS

1. have not installed the binary move in CIMResponseData. Please run

with OPP off.

2. Some problem in the processing so we are getting server crashes.

Right no I am guessing that this is in the binaryCodec and am going to

expand the test tools to allow testing through the localhost.

3. Still way to many TODO and KS comments and KS_TEMPS. Removing bit by bit.

4. Env variable connection for the config parameters not installed.

- Runtime variable connection for the config parameters not installed. That

has been made into a separate bug (see bug 9819)

5. Issue with the threaded timer. For some reason during tests it

eventually calls the timer thread with trash for the parm (which is
