Abstract instance running states into a list

This removes some manual checks from a few places in the code with a
single list defined once.

Add a 'movable' flag on instances

This will be used instead of checking for no secondary and for
simplifying 'do not touch' instances.

Add a tags attribute to instances

… and read it in all the loaders. hscan is modified to save it to the
files it generates.

The attribute is not yet used in any place.

Change the default dynamic usage to baseUtil

This fixed the unbalanced secondary instances on partially empty
clusters, and helps in general for the cases where real utilisation data
is not available.

hspace: show tiered-alloc stats in the output

This is a first attempt to get a readable output of tiered allocation
stats in hspace's output. Not very nice, but it should be somewhat

Add support for shrinking instance specs

This patch adds a function that, for some given failure modes, shrinks a
given instance in the hope that allocation will succeed when retried
with the new spec.

Some small style fixes

Add initial structure for utilisation balancing

This patch adds the datatypes and modifies the nodes and instance types to have
such attributes. They are not used yet in any way.

181d4e04 10/15/2009 11:49 am Iustin Pop

Add an explicit export list to Instance.hs

This exports all functions, but it's still good to have.

Style change: node and instance attributes

This changes from a_b to aB in all node and instance attributes, to
match the standard Haskell style. Also attributes that should have been
camel-cased but weren't were changed (e.g. plist → pList, pnode →

Add a new vcpus attribute to instances

This patch adds reading of vcpu count for instances, in preparation for
using the vcpu ratio in cluster scoring.

Small doc change

And an alignment issue.

e2fa2baf 06/01/2009 12:55 pm Iustin Pop

Add copyright/license information

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

Lots of documentation updates

This patch does only doc build changes, doc changes and function move
around (for more logical documentation). It should have no impact at all
on the code.

Add type synonyms for the node/instance indices

This is a first step towards full datatype renaming. That requires more
changes, so at first we only want to document clearly what is a node
index, what is an instance index, and what is a plain Int.

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.

Add a small class for Nodes and Instances

Since both nodes and instances support some common functionality (names
and indices), we add a class so that we can access these attributes in a
generic way.

Add back names to nodes/instances

In order to simplify the data structures, we add back the name on the
node and instance objects. We still keep the index for, well, indexing,
but we will use the name directly from the object, in order to get rid
of the ktn/kti arguments which are passed around everywhere.

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...

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...

Pass actual types to node/instance constructors

This patch changes the parameters passed to the node and instance
constructors from generic Strings (which are then parsed via “read”) to
the actual used types, by converting them earlier in Cluster.loadData.

Introduce a namespace for the modules

The modules are moved from the ‘top’ namespace to ‘Ganeti.HTools’, in
compliance with standard practices.
