is a message protocol and that the same code can be used on both the

differences. There are still a few TODOs in the code, but none should
be a show stopper. Many pylint warnings have been fixed, too.

Convert rpc results to a custom type
For a long time we had the problem that both RPC-layer errors and
results from the remote node share the same "valuespace". This is
because we shouldn't raise an exception when only one node failed
(and lose the results from the other nodes).
This patch attempts to address this problem by returning a special
object from RPC calls, which separates the rpc-layer status and the
remote results into different attributes.
All the users of rpc (mainly cmdlib, but also bootstrap and the
HooksMaster in mcpu) have been converted to this new model. The code has
changed from, e.g. for boolean return types:
if not self.rpc.call_...
to
result = self.rpc.call_
if result.failed or not result.data:
^ rpc-layer error |
- result payload
While this is slightly more complicated, it will allow cleaner checks in
the future; right now the code is just a plain port, without
optimizations.
There's also a "result.Raise()" which raises an OpExecError if the
rpc-layer had errors.
One side-effect of the patch is that now all return types from the
rpc.call_ functions are of either RpcResult (single-node) or dicts of
(node name, RpcResult); previously, some functions were returning
different object types based on error status.
The code passes burnin (after many retries :).

jqueue: Log progress and load jobs one by one
By logging more information, a user can see how far it is in inspecting
the queue. This can be useful with a large number of jobs. Also, instead
of loading all jobs in one go, load only the list of job IDs and then
load jobs one by one.

Implement support for multi devices changes
This big patch adds support for:
- changing NIC/disks in the multi-device model
- adding/removing NICs
- adding/removing disks
The patch is big and not very nice; the error checking paths are not
very clear.
The biggest problem is that from a simple instance.ATTR=VAL change
(which didn't throw errors before) now we are creating and removing
disks in this LU.

Slight change to the LU initialization code
This patch adds support for a separate LU.CheckArguments() method which
should do syntactic checks without holding locks and without polluting
the ExpandNames which is a lock-related function. See for example the
FIXME in LUSetInstanceParams.CheckPrereq.
The patch also removes the REQ_MASTER and IsCluster checks since with
the current architecture, inside LU code we are always in a valid
cluster and we are always running on the master node.
