Add copyright/license information
This doc-patch adds copyright and license information to (hopefully) allneeded files.
Lots of documentation updates
This patch does only doc build changes, doc changes and function movearound (for more logical documentation). It should have no impact at allon the code.
Finish removal of unused params from PeerMap
This completes the removal started earlier byt removeing the need topass the number of nodes to Node.buildPeers, which is now unused.
Add test infrastructure and initial tests
This patch adds a QuickCheck-based test infrastructure and initial testsbased on it. The PeerMap module has a 100% coverage ☺
Side-note: one has to read the source of QuickCheck to see how to use it(especially the Batch submodule), the docs are not enough…
Remove unused parameters from PeerMap creation
We remove some unused arguments (added way back for compatibility withArrays, which we didn't use in the end). This makes the code clearer(and doesn't need the Ndx type to be an instance of Num).
Add type synonyms for the node/instance indices
This is a first step towards full datatype renaming. That requires morechanges, so at first we only want to document clearly what is a nodeindex, 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 onesimport it, from the previous (opposite) situation. This will allow inthe future to use newtypes for the index and name types.
Remove some extraneous uses of ktn/kti
Since we have Node/Instance.name, we can now simplify a few constructs.
Add a small class for Nodes and Instances
Since both nodes and instances support some common functionality (namesand indices), we add a class so that we can access these attributes in ageneric way.
Add back names to nodes/instances
In order to simplify the data structures, we add back the name on thenode 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 ridof the ktn/kti arguments which are passed around everywhere.
More code reorganizations
This new big patch does a couple of more cleanups in the loading of datachapter: - 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 commonformat” 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 support for 'offline' nodes
This patch drops compatiblity with Ganeti 1.2 and adds support foroffline nodes in the cluster. When reading from RAPI, the drained nodesare considered offline so that we don't allocate on them too.
Update all needed node fields on f_mem change
This fixes the setFmem function which didn't compute other relatedfields after free memory change. Ideally, this should be abstracted sothat add/remove Pri and similar functions could reuse it instead ofduplicating code.
Fix interaction between down instances and nodes
If an instance is down, it's memory is not reflected in the node usedmemory, and thus the node free memory is higher than the actual value.This patch deducts the memory for such instances from the node free...
Show the x_mem/i_mem in node list
This patch adds checking of cluster data in the binaries and display ofnode's x_mem/i_mem in the node list.
Add a new node filed x_mem
Nodes can have some memory unaccounted for, due to (e.g.) hypervisoroverhead, rounding errors in reporting, etc.
It is better if we model this memory explicitly instead of hiding it,and actually since the n_mem addition it is actually required to do so....
Remove unused and obsolete function
The Node.str function is very old and is not useful since the nodeobjects have much more fields today. This patch removes it, and ifneeded a full node display can be done via ‘show’.
Add node memory field to Node objects
This patch adds a new n_mem field to the node objects, and implementsread/save/show support for it. The field is not currently used (exceptin the node list) but will be used for checking data consistency andinstance up/down status.
Pass actual types to node/instance constructors
This patch changes the parameters passed to the node and instanceconstructors from generic Strings (which are then parsed via “read”) tothe actual used types, by converting them earlier in Cluster.loadData.
Some small changes in preparation for hscan
This patch does some small changes: - fixes a comment - export more node functions (unneeded now, but hscan will use them) - fixes Makefile rule for building the programs
Show offline nodes in the node status list
This patch adds a new ‘-’ flag for the node status which denotes offlinenodes.
Add a new 'offline' Node attribute
This patch adds a new node attribute - offline - which will serve toskip nodes from the target candidate list.
Small doc update in Node.hs
Introduce a namespace for the modules
The modules are moved from the ‘top’ namespace to ‘Ganeti.HTools’, incompliance with standard practices.
