[PATCH 0 of 2] SD: check client given object path
by Heidi Eckhart 05 Feb '08

05 Feb '08

To enable the check of the client's given object path for Devices, the first tiny reorg in the Device provider is necessary. Thereby the get_device() function is made available for external use. The second patch fixes the missing check of the client's given object in SystemDevice provider - for both directions.

[PATCH 0 of 4] #3 - RPCS and RPCC ignores supported hypervisor type and wrong object path, adopt changes to HS
by Heidi Eckhart 05 Feb '08

05 Feb '08

This patch set is now the combination of the one patch against RPCS and the two patches against RPCC, I sent out on friday. The reason to combine these three patches in one patch set is, that both provider - RPCS and RPCC - look very similar now. This brought me to the idea, that it is possible to also define a common interface for instances providers - as this is already done for associations -, where the common functions could do a main part of the error handling (which is currently done again and again in each single provider itself). In addition patch 4 updates HS (thanks to Kaitlin) with the new interface of RPCS. diff to patch set 2: - renamed parameter getInstance to is_get_inst for style conformance

[PATCH 0 of 2] [CU] Migration Indication related libcmpi changes
by Jay Gagnon 05 Feb '08

05 Feb '08

These provide libcmpiutil support copying instances and raising indications, which are required by the new MigrationIndication provider.

[PATCH 0 of 2] MigrationIndications
by Jay Gagnon 05 Feb '08

05 Feb '08

These two patches together are dependent on some libcmpiutil changes I'll be sending out shortly; one for dup_instance, and another for raise functionality. The four patches together give us Migration Indications. Any time VSMigrationService is used to trigger a migration, the appropriate indications will be fired. The big caveat for these patches is that migration is still a bit flaky on my system, so while I have tested that the "started" and "failed" indications work I haven't had a chance to see "succeeded" fire. I have no reason to believe it won't, because of the way the raising happens, but it would be good to confirm.
