      Change the Node.group attribute · 10ef6b4e
      Iustin Pop authored
      Currently, the Node.group attribute is the UUID of the group, as until
      recently Ganeti didn't export the node group properties. Since it does
      so now, we make the following changes (again apologies for a big
      - we change the group attribute to be an index, similar to the way an
        Instance.pnode and snode attributes point to the parent node(s)
      - on load, we read the group.uuid attribute and we use that to lookup
        the actual group index, from previously-loaded groups info
      - this means that we now first read groups, then read nodes using the
        group info, and then read instances using the node info
      This patch leaves a few functions showing the group index (ugly since
      it's htools internal), will be converted later.

      Rework the data loader pipelines to read groups · a679e9dc
      Iustin Pop authored
      This (invasive) patch changes all the loader pipelines to read the node
      groups data from the cluster, via the various backends. It is invasive
      as it needs coordinated changes across all the loaders.
      Note that the new group data is not used, just returned.

      Rework the types used during data loading · 99b63608
      Iustin Pop authored
      This improves on the previous change. Currently, the node and instance
      lists shipped around during data loading are (again) association lists.
      For instances it's not a big issue, but the node list is rewritten
      continuously while we assign instances to nodes, and that is very slow.
      The code was originally written for small (10-20 node) clusters, and
      today with multinodes… :)
      Rewriting to use Node.List/Instance.List makes a bit of a messy patch,
      but it allows to remove some custom functions for assoc. list
      processing, and also some custom unittests.
      At the end, the load time is almost halved, and we spend time now just
      in the string parsing code (which is, as we know, slow…).

      Convert some leftovers to NameAssoc · 6ff78049
      Iustin Pop authored
      The type alias NameAssoc has been introduced a long time ago, but there
      are some few not-yet-converted cases. In preparation for changes to that
      type, let's make sure we use it consistently.

      Use the oper_ram field if available · 6402a260
      Iustin Pop authored
      For the RAPI and LUXI backends, we can get the actual memory usage (if
      instances are running) via the oper_ram, whereas backend/memory only
      tell what the instance will use at the next boot.
      Not using oper_ram means that the node model is flawed and we consider
      wrong values for the instance's memory (resulting sometimes in hilarious
      values such as x_mem = -700 MB).

      Change the Utils.fromObj signature · 262f3e6c
      Iustin Pop authored
      Currently the fromObj function takes a JSON object which is then
      converted into a list of (String, JSValue) in which we make a lookup.
      However, most of the callers of this function call it repeatedly on the
      same object, which means we do the object→list conversion repeatedly.
      This patch converts it to take directly the list, and converts its
      callers to do the conversion themselves (and only once).
      While this is not in the hot-path today, it would be if we ever were to
      process much data over Luxi (or RAPI), and is a good cleanup in any

      then modifies Rapi.hs to use them as the connect and general curl
      Rapi could be improved more, as currently we wait double the total

      Allow overriding the RAPI port/scheme · e015b554
      Iustin Pop authored
      This patch adds a very dumb way to override the port and scheme for
      RAPI: if the master string doesn't contain a colon, we consider it a
      simple hostname specification, and thus prepend ‘https://’ and append
      ‘:5080’, (the default RAPI port); otherwise, we consider it a fully
      specified URL, and don't do any mangling to it.
      This allows to use saved RAPI responses in testing, with the “file://”
      scheme, or to use another port or non https mode with an actual RAPI

      Switch from hand-written monads to a real one · 942403e6
      Iustin Pop authored
      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.
      Many of the functions could now be written in a generic-monad style,
      instead of Result specifically, but that will come in future patches.
      IAlloc.hs also has some unrelated patches.
