      jqueue: Change model from per-job to per-opcode processing · be760ba8
      Michael Hanselmann authored
      
      
      In order to support priorities, the processing of jobs needs to be
      changed. Instead of processing jobs as a whole, the code is changed to
      process one opcode at a time and then return to the queue. See the
      Ganeti 2.3 design document for details.
      
      This patch does not yet use priorities for acquiring locks.
      
      The enclosed unittests increase the test coverage of jqueue.py from
      about 34% to 58%. Please note that they also test some parts not added
      by this patch, but testing them became only possible with some
      infrastructure added by this patch. For the first time, many
      implications and assumptions for the job queue are codified in these
      unittests.

      jqueue: Factorize code waiting for job changes · 989a8bee
      Michael Hanselmann authored
      
      
      By splitting the _WaitForJobChangesHelper class into multiple smaller
      classes, we gain in several places:
      
      - Simpler code, less interaction between functions and variables
      - Easy to unittest (close to 100% coverage)
      - Waiting for job changes has no direct knowledge of queue anymore (it
        doesn't references queue functions anymore, especially not private ones)
      - Activate inotify only if there was no change at the beginning (and
        checking again right away to avoid race conditions)
