Add copyright/license information
This doc-patch adds copyright and license information to (hopefully) allneeded files.
Cleanup an old function
Also replace a type with its synonim.
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.
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)...
Initial work on hail
This makes hail compile and get a request parsed via IAlloc, but nothingmore.
Generalize some Result function into monad ones
We don't really needed, but is more clean like this.
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 theextra constructs. Hopefully the code is also more clear....
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 the IAlloc module
We know have a working parseData function that returns the node andinstance data. This uncovered bad support for non-drbd instances ☹
Move the JSON utilities to Utils.hs
This patch moves the generic/reusable JSON functions to Utils.hs, sothat they're shared between RAPI/IAlloc.
hbal: Abort for invalid offline node names
Since it's easy to pass a wrong node name as offline, we should abortinstead of silently ignoring it.
Split common CLI functionality into a module
This patch moves the common CLI functionality (as much as currentlypossible) into a separate module. This means we only have one parseOptsand that Utils.hs doesn't keep this kind of functions anymore.
Introduce a namespace for the modules
The modules are moved from the ‘top’ namespace to ‘Ganeti.HTools’, incompliance with standard practices.
