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.
Add a copy of Rapi.HS as IAlloc.hs
This will be used in two ways: - format the response to Ganeti (easy, implemented) - parse the input data and build the node/instance lists (hard :)
hbal: Add a new min-score option
This new parameter causes the algorithm to finish (or even not start atall) if we reach/have a score better than it.
hbal: Change hardcoded tests to monadic composition
In some case we manually do “if isNothing … then Nothing else …”, whichcan be very easily replaced with a monadic construct in the Maybe monad.
Increase allowed missing memory to 512MB
Since Xen seems to “steal” some amounts of memory (depending on totalnode memory), we increase the maximum allowed missing memory to 512MB,based on gathered data from multiple machines.
Add reading the file names from env vars
This patch adds support for selecting the instance/node file names viatwo environment variables (HTOOLS_NODES, HTOOLS_INSTANCES).
Unfortunately we still have lots of duplicated code, since the optionsare not unified.
Implement writing the command list to a script
This patch adds support in hbal for writing the command list to a shellscript, with error checking and allowing for early exit.
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.
More documentation updates
This removes most of the content of the README file (obsoleted by newalgorithm and man pages), modifies the Makefile to include the builtdocumentation in the source archive (so that haddock/hscolour are notneeded) and updates the haddock-prologue with current information.
