Convert the rest of the pipeline to ClusterData
This patch converts the backends and mergeData to the new ClusterDatatype.

Change the Node.group attribute
Currently, the Node.group attribute is the UUID of the group, as untilrecently Ganeti didn't export the node group properties. Since it doesso now, we make the following changes (again apologies for a bigpatch):
- we change the group attribute to be an index, similar to the way an...
Luxi: read the allocation policy from the cluster
Rework the data loader pipelines to read groups
This (invasive) patch changes all the loader pipelines to read the nodegroups data from the cluster, via the various backends. It is invasiveas it needs coordinated changes across all the loaders.
Note that the new group data is not used, just returned....
Rework the types used during data loading
This improves on the previous change. Currently, the node and instancelists shipped around during data loading are (again) association lists.For instances it's not a big issue, but the node list is rewrittencontinuously while we assign instances to nodes, and that is very slow....
Convert some leftovers to NameAssoc
The type alias NameAssoc has been introduced a long time ago, but thereare some few not-yet-converted cases. In preparation for changes to thattype, let's make sure we use it consistently.

Luxi: read the node uuid from the cluster
This makes the code incompatible with Ganeti pre-2.4.
Node: add the node group's UUID
This is not used anywhere yet, and the backend are all just adding thedefault UUID, not the real one.
The patch also allows displaying the group UUID in the node list.
Luxi loader: split parsing from loading
Ignore nodes which are not vm_capable
This break compatibility with Ganeti pre-2.3.
Change the Luxi operations structure
Currently, we define the LuxiOp type as a simple enumeration, and leavethe arguments structure to the users of the Ganeti.Luxi module. This issuboptimal for a couple of reasons: first, we decouple the operationtype from operation arguments, and that means we don't use the type...
A number of small fixes from hlint
Fix unused imports for ghc 6.12
GHC 6.12 has become more picky about unused imports, so we need toremove/tighten some of them.
Use the oper_ram field if available
For the RAPI and LUXI backends, we can get the actual memory usage (ifinstances are running) via the oper_ram, whereas backend/memory onlytell what the instance will use at the next boot.
Not using oper_ram means that the node model is flawed and we consider...
rapi, luxi: treat drained nodes as offline
Commit e97f211 changed the iallocator backend to handle drained nodes asoffline. This commit completes that change by making the rapi and luxibackend do the same (the text backend ignores any '?' values which are...
Fix typo breaking LUXI backend
This really shows the need for actual dist-time full testing (notunittests).
Read cluster tags in the LUXI backend
Introduce support for reading the cluster tags
While these are not actually populated from the backends, and all theprograms ignore them, this patch contains the changes in the functiontypes required.
Add a tags attribute to instances
… and read it in all the loaders. hscan is modified to save it to thefiles it generates.
The attribute is not yet used in any place.
Small change in some list arguments
This is simpler than the concat operator.
Enhance the error reporting for Rapi and Luxi
Currently the JSON conversion in Rapi and Luxi are giving somethinglike: Error: failed to load data. Details: Unable to read Double
This doesn't tell one where the error is (in a node specification? and...
Split the Luxi generic parts from the loader
The Luxi loader implements both a generic Ganeti Luxi client and theloader; it is better if these two are separated. The patch adds aGaneti/Luxi.hs (not under HTools!) since that is generic for Ganeti, andnot related necessarily to htools.
Turn on, and fix, more warnings
The Makefile was intented to be -Wall and not simply -W, but I missedthat. This enables more warnings and also enables -Werror (except forthe tests).
Fix luxi recvMsg for messages bigger than 4K
This patch fixes a logic bug in luxi that breaks receive of messagesbigger than 4096 bytes. The send message is not impacted as it uses adifferent algorithm.
Fix a few hlint errors
Initial commit of the luxi backend
This patch adds a luxi backend that allows direct query of the masterdaemon on the local node. This patch doesn't enable the backend to beused.
There are a couple of things still missing in the implementation: - we don't have a master timeout in reads and writes, only a...
