Add copyright/license information

This doc-patch adds copyright and license information to (hopefully) all
needed files.

Change the module import hierarchy

This patch makes the Types module a base module, and Node/Instance ones
import it, from the previous (opposite) situation. This will allow in
the future to use newtypes for the index and name types.

Remove the ktn/kti from second half of loading

This removes the return of ktn/kti from Loader.mergeData and associated
functions.

Remove most uses of ktn/kti

This patch removes all uses of ktn/kti from the past-loader stages.

Remove some extraneous uses of ktn/kti

Since we have Node/Instance.name, we can now simplify a few constructs.

Move checkData from Cluster to Loader

This moves the remaining loading function to Loader (together with its
associated support functions).

Introduce a class for CLI options

This patch generalizes a little the CLI handling by not passing in a
special function for help and such, but instead requiring that the
options object supports some common functionality.

More code reorganizations

This new big patch does a couple of more cleanups in the loading of data
chapter:
- introduce a Types module that holds most types (except the base
Node/Instance/etc.) so that multiple other modules can use these
(instead of only Cluster and its users)...

Rework the loader model

This big patch changes the loader model from “string data as common
format” to actual object structures as common format.

The text loading function move from Cluster.hs to a new Text.hs module,
some common functions are moved to a new Loader.hs module, and the...

Convert Cluster.loadData to Result return

This patch changes Cluster.loadData to return a Result, instead of
directly the values; this will allow us to return meaningful error
values (e.g. when an instances lives on unknown node) rather than simply
abort. Currently the result is always an Ok, the actual signalling of...

Allow hscan to save data for fully-spec'd URLs

In case we pass a fully-specified URL to hscan, currently it will use as
is and that means the directory in which we want to save the status
files changes from what we mean. This patch changes hscan to replace all...

Switch from hand-written monads to a real one

This big patch converts from our home-grown monad-like constructs
(the Either stuff) to a real, Either-like-but-another-name monad.

We introduce a “Result a” monad, and this allows dropping many of the
extra constructs. Hopefully the code is also more clear....

Add support for 'offline' nodes

This patch drops compatiblity with Ganeti 1.2 and adds support for
offline nodes in the cluster. When reading from RAPI, the drained nodes
are considered offline so that we don't allocate on them too.

Fix interaction between down instances and nodes

If an instance is down, it's memory is not reflected in the node used
memory, and thus the node free memory is higher than the actual value.
This patch deducts the memory for such instances from the node free...

Add a new instance field denoting run status

This patch modifies Rapi, the Cluster.loadData and hscan serialization to load
and save the instance run status. At instance level, we add both a boolean
field denoting the true/false run status, and a string field which holds the...

Show the x_mem/i_mem in node list

This patch adds checking of cluster data in the binaries and display of
node's x_mem/i_mem in the node list.

Split common CLI functionality into a module

This patch moves the common CLI functionality (as much as currently
possible) into a separate module. This means we only have one parseOpts
and that Utils.hs doesn't keep this kind of functions anymore.

Add node memory field to Node objects

This patch adds a new n_mem field to the node objects, and implements
read/save/show support for it. The field is not currently used (except
in the node list) but will be used for checking data consistency and
instance up/down status.

Small change in hscan

This fixes a mistake between Int/Integer. Should be more careful :)

Add the hscan tool

This patch adds an hscan tool that loads data from clusters via RAPI and
writes it to files that can be later used offline.
