      Improve the standard deviation computation · 7570569e
      Iustin Pop authored
      
      
      This does just two passes, instead of three, over the list. This reduces
      the overall runtime well enough (~25%) in some tests, but it's not
      reproducible using profiling, so I don't know how much the function
      itself is being sped-up.
      
      Note: this is written via `seq`s, and not BangPatterns. Since it's just
      one case, adding BangPatterns just for it wasn't a big gain.
      
      Thanks to Lécz Balázs for the impetus to improve this!

      hbal: change handling of signal · 543e859d
      Iustin Pop authored
      
      
      Currently, hbal does a one-two signal handling, where the first signal
      causes graceful termination, and the second one an immediate on (either
      SIGINT or SIGTERM can be used, interchangeably). However, this poses a
      timing problem: if two programs want to send a graceful termination
      request, they cannot do that without careful coordination.
      
      To fix this, we change to code to handle the signal separately: SIGINT
      (^C) sends graceful termination, while SIGTERM sends immediate
      termination. This should allow easier controlling of hbal.

      Fix tag exclusion weight · 306cccd5
      Iustin Pop authored
      Currently, the tag exclusion metric has a weight of one, which means
      there might be cases where we won't move instances around because it
      upsets the cluster metrics. However, we do want to make a higher effort
      for cleaning up tag collisions, so we increase the weight to an
      empirically-determined value of 2.

      Force UTF-8 locale for pandoc invocation · 718f135d
      Iustin Pop authored
      Pandoc 1.5.x uses the locale information to parse its input files (only
      1.5, pre and post version use always UTF-8). Hence we need to enforce a
      UTF-8 locale for proper parsing of input files.

      hbal: implement user-friendly termination requests · 03cb89f0
      Iustin Pop authored
      Currently, hbal will abort immediately when requested (^C, or SIGINT,
      etc.). This is not nice, since then the already started jobs need to be
      tracked manually.
      
      This patch adds a signal handler for SIGINT and SIGTERM, which will, the
      first time, simply record the shutdown request (and hbal will then exit
      once all jobs in the current jobset finish), and at the second request,
      will cause an immediate exit.

      Add some more debugging functions · adc5c176
      Iustin Pop authored
      These are just variations of the standard debug, but are provided for
      simpler code, since lazyness is something causing non-computation of
      debug statements.

      Fix ReplaceSecondary moves for offline nodes · 74e89a14
      Iustin Pop authored
      The addition of a new secondary on a node is doing two memory tests:
      - in strict mode, reject if we get into N+1 failure
      - reject if the new instance memory is greater than the free memory (not
        available memory) on the node
      
      The last check is designed to ensure that, irrespective of the other
      secondary instances on this node, we are able to failover/migrate the
      newly-added instance.
      
      However, we should allow this, if the instances comes from an offline
      node, which doesn't offer anything (not even disk replication).
      Therefore this patch makes this check conditional on the strict mode.
