[PATCH] SD doesn't return instances in all cases

# HG changeset patch # User Kaitlin Rupert <karupert(a)us.ibm.com> # Date 1196460977 28800 # Node ID 1776beb36f5cffcfad4e581a8841f77f20bc3927 # Parent d5af3e219c22e8b32de64c69a29aea970ab6a9a4 SD doesn't return instances in all cases. Virt_SystemDevice doesn't return instances when CIM_ManagedElement is passed as a result class argument. This only applies to the VM to device case (see failint query below). The problem is that we use the result class to determine which device type to return. If no result class is specified, we return all associated devices. However, if CIM_ManagedElement is specified, we are unable to match the device type, and we return nothing. I think all of this can be removed because filter_results() in libcmpiutil should remove the need for this kind of checking.

[PATCH 0 of 9] Reorganized association provider registration
by Heidi Eckhart 05 Dec '07

05 Dec '07

The association provider was registered for each subclass with a different name. That caused duplicated instances as the same provider gets called twice, but has no chance to figure out for which registration. This patch set tries to fix it. Please review. Thanks. Based on: - #2 Fix (again) VSMCaps and ElementCap - Remove devid-style InstanceID support from ELEC and EC

Hi, I try to test VirtualSystemManagementCapabilities and get results as follows: "wbemcli ein http://root:password@localhost:5988/root/virt:Xen_ResourcePoolConfiguration…" localhost:5988/root/virt:Xen_ResourcePoolConfigurationCapabilities.InstanceID="" As a property of ResourcePoolConfigurationCapabilities, is InstanceID need to set in provider?

[PATCH 00 of 12] #3 - Adoption of changes to std_assoc struct in std_association for all associations
by Heidi Eckhart 04 Dec '07

04 Dec '07

Sorry saw Kaitlin's comments too late :(. This is the follow up patch to the API changes made in std_association. The struct std_assoc does now take lists for source, target and assoc classnames. Diff tp patch set #1: - fixed SD: former patch specified HostSystem as group_component instead of ComputerSystem - fixed HS: class ResourcePoolConfigurationService was missing for dependent - fixed SDC: fixed check against CMPIRc in alloc_cap_to_rasd; this still needs to be fixed in another patch, as ResourceType is no key property but is handled as one Diff to patch set #2: - fixed RAFP: need to specify subclasses of ResourceAllocationSettingData - fixed: SDS: need to specify subclasses of ResourceAllocationSettingData - fixed VSSDC: need to specify subclasses of ResourceAllocationSettingData

[PATCH 0 of 2] Remove devid-style InstanceID support from ELEC and EC.
by Kaitlin Rupert 04 Dec '07

04 Dec '07

Removed devid-style InstanceID support from ELEC - this class now uses just the name of domain. This caused a needed update in EC - cap_to_cs() no longer needs to parse devid-style InstanceIDs.

[PATCH 0 of 2] #2 Fix (again) VSMCaps and ElementCaps
by Dan Smith 03 Dec '07

03 Dec '07

There was a lot of cruft in both VSMCaps and ElementCaps around generating a dynamic InstanceID with the HostSystem.Name in it that is really not necessary. This set just changes to a static InstanceID for VSMCaps and removes all the supporting code that it obviates. Changes: - Just a rebase on tip
