| Urgent |
|
| ====== |
|
| | |
| - Fix problem with cimserver not running properly when run without |
- Need meta-client API. |
| options. |
|
| | |
| - Put cimserver back in the makefile. |
- Do we need strings to represent NULL and empty (what if the standard |
| |
adds something where a string parameter can be null distinguished from |
| |
an empty value). |
| | |
| - Resolve whether the backslash should be permitted int namespaces. |
- Expose repository inheritance tree. |
| | |
| - Work on developer's guidlines document. |
- Look at not passing HTTP header to CIM request decoder queue. |
| | |
| No STL (or other third party software). |
- Propagate message key for all messages pertaining to a particular |
| Indent by three. |
request. |
| Braces on the next line. |
|
| Always run regression tests before committing and do cvs -q update. |
|
| | |
| - Add CIMOM handle to provider interface. |
- Run Purify on all sources (port to Sun first). |
| | |
| - Fix case sensitivity problems in repository (just add an _Open method |
- Rework Pegasus to use asynchronous I/O. |
| that ignores the case of the file). |
|
| | |
| - Add newly implemented repository operations to protocol and to |
- Finalize export client/server: |
| dispatcher. |
|
| | |
| - Change INVALID_CLASS exceptions to NOT_FOUND (they're wrong in |
- Covert GetClass operation to DeliverIndication operation. |
| Repository). |
|
| | |
| - Add tracing of output HTTP messages. |
- Rework export-client to asynchronously process responses |
| |
(instead of the RPC style used now). |
| | |
| - Need CIMInstance::removeMethod() and CIMInstance::removeProperty(). |
- Need meta-export-client (with connection management). |
| - Add a exists namespace operation under the repository stuff. Maybe we |
|
| need more than this. |
|
| | |
| Topical To-Do List |
- Implement disconnect() logic. |
| ================== |
|
| | |
| - Sun uses string message-ids. Pegasus uses integer. |
- Remove keys from messages? |
| Sun uses 2000.5.12.... format. Changed Pegasus to |
|
| use string message-ids. DONE. |
|
| | |
| - Some clients send '\n\n' to terminate HTTP headers. |
- Get rid of unused source code (dealing with channels and TCP). |
| We were only accepted '\r\n\r\n'. DONE. |
|
| | |
| - Provide way of printing out command line options help from cimserver. |
- Rethink the useage of queue-ids in messages and how requests and |
| |
responses are matched up. Queue-ids are only used on the server |
| |
side. Perhaps a more general mechanism can be found. |
| | |
| - GetInstances() and GetClasses() need to use iterators on |
- Fix bug in which the messageId is calculated inside the XmlWriter. |
| provider and repository end. Otherwise, all classes or instance |
It should be calculated by the caller. |
| to be enumerated, must be sucked into memory. |
|
| | |
| - Template bloat reduction. |
- Delete CIMOperations.h. |
| | |
| - Use YACC on Linux. |
- Get rid of message keys? They don't seem to be used. |
| | |
| - Need a tool to say which features are supported by a compiler. |
- Fix bug in src/Pegasus/Client/tests/Client in which associators() |
| |
fails and says class does not exist (seems to happen in debug mode |
| |
only). Disappears when I/O is enabled. |
| | |
| - Support unloading of dynamic libraries (presently only load() is |
- Replace old headers with new ones (co-ordinate with team). |
| supported). |
|
| | |
| - Instances: |
- Get rid of usage of System (use since it |
| | |
| - Implement CIMRepository::getProperty() |
- Migrate to use of Linkage.h files. |
| | |
| - Implement CIMRepository::setProperty() |
- Document that lex and yacc are no longer a requirement to build |
| |
Pegasus. |
| | |
| - Implement CIMRepository::deleteInstance() |
- Figure out how to handle very large CIM respones and possibly |
| |
requests too. |
| | |
| - Implement CIMRepository::modifyInstance() |
- Integrate client/server tests into make system somehow. |
| | |
| - Implement CIMRepository::enumerateInstances() |
- Note that it is possible to remove an class and still have association |
| |
classes which refer to it. |
| | |
| - Implement CIMRepository::enumerateInstanceNames() |
- Class inheritance not taken into consideration when resolving the |
| |
AssocClass |
| | |
| - Handle inheritance in all instance operations. |
- It seems that associatios() will fail when AssocClass is a super |
| |
class of the class which is in the association instance table. |
| | |
| - Double check that all these operations work across protocol. |
- Should there be a single associations table for the entire repository |
| |
or should there be one per namespace as there is now? |
| | |
| - Check that they have keys during validation. |
- If it is the case that a reference may only refer to an instance, |
| |
then we must derive new types for representing object paths. |
| | |
| - Associations: |
- Many CIM operations interfaces are incorrect: GetInstance() for example |
| |
takes a namespace and a CIMReference (which also may contain the |
| |
namespace). According to the standard, it should take an "InstanceName". |
| | |
| - Implement CIMRepository::referencesOf() |
- Need way of signaling the cimserver so that it will reload the |
| |
class inheritance table (after a MOF compile). |
| | |
| - Implement CIMRepository::associatorsOf() |
- Revisit use of namespace v.s. objectName in all CIM operations. |
| | |
| - Implement protocol stubs for these operations. |
- What do we do when getInstance() is called and the nameSpace is |
| |
provided both as an argument and as part of the instance name? |
| | |
| - Exceptions: |
- ReferenceNames should return classes not just instances? |
| | |
| - Force __FILE__ and __LINE__ argument on every usage of CIMException. |
- Remove final const from const methods in non-const CIM element classes. |
| | |
| - Clean up and consolidate exception classes. |
- Null vs. empty CIM/HTTP parameters. |
| | |
| - Propagate underlying error messages across the CIM protocol. |
- Resolve constness problems. (get rid or Const classes?) |
| | |
| - References: |
- Change CIMReference to CIMObjectPath? |
| | |
| - Validate arguments to CIMReference compound constructor and modifiers. |
- Finish associations. |
| (namespaces, hosts, classnames, and keybindings) |
|
| | |
| - Be sure that escape sequences are handled inside of object names. For |
- Provide CIMOM Context. |
| example: |
|
| | |
| X.key1="Hello \"You\"" |
- Complete conventions document. |
| | |
| - Protocol: |
- The CIMServer.exe program should probably create the logs directory |
| |
under PEGASUS_HOME. |
| | |
| - Improve protocol tracing to show messages in both directions. |
- Clean up exceptions. |
| | |
| - The TCPChannel::writeN() method blocks when the client and server |
- Resolve redundancy in which the namespace is passed to certain methods |
| are in the same process. That is because the client cannot read |
(getClass) and the CIMReference itself may contain a namespace arguent. |
| anything as long as writeN() is blocked on a synchronous write. |
|
| | |
| - Figure out how to handle getProperty() return type. |
- Implement consistency and constraint checking on classes and instances. |
| | |
| - Provide ACE Channel implementation (for porting purposes)? |

| | |
| - Handle PARAMETER.REFARRAY in Procotol? |
- Consider eliminating const CIM element classes. |
| | |
| - Ignore extraneous XML elements (loosely valid). |
- Support for NULL property lists (in interface and protocol). |
| | |
| - Porting: |
- Rename tests (prepend "Test" to each test). |
| | |
| - Replace "std::something" with "STD(something)" |
- Fix bug with cimserver.exe causing it to fail to start without te |
| |
"-l" option. |
| | |
| - Replace "using namespace std" with "USING_NAMESPACE_PEGASUS" |
- Resolve whether the backslash should be permitted in namespaces. |
| | |
| - Aesthetics/Consistency/Usability: |
- Create CIMOMContext (interface to CIMOM used b the provider). |
| | |
| - Change getLength() and getSize() to just size(): "Brevity is the soul |
