      Improve the gnt-* list field selection · 48c4dfa8
      Iustin Pop authored
      This patch allows the '-o' option to the list subcommands to add more
      fields to the default list instead of replacing the default list by
      prefixing the fields list with '+'.
      
      The patch also moves the listing (in the help output) of the default
      field list from hardcoded to built at runtime from the actual list.

      Wrap exception in _DistributeConfig code · 9ff994da
      Guido Trotter authored
      nodelist.remove(X) could potentially raise a ValueError (even if the chance
      that the current node is not in the list are pretty scarce, and its absence
      should raise a red flag anyway). If this happens let things go on, as that's
      what the code which previously distributed the config did.

      Currently we get the list of nodes, and for each one extract all its info, and
      just to exclude it if the name matches ours. Since the list of nodes is a list
      of names just use .remove() to exclude ourself from it, and use that list
      directly.

      Add a LU Hooks notification function · 1fce5219
      Guido Trotter authored
      Previously LUs could be failed by pre-hooks, and post-hooks just had effects by
      themselves. This patch allows a LU to define the HooksCallBack function if it
      wants to know about its hooks' results and alter its results in response.
      
      The ChainOpCode execution path contains some commented out hooks code, which
      this patch modifies to run the HooksCallBack function, so this is not forgot if
      it ever gets uncommented out.

      Since NoHooksLU defines HPATH as None, BuildHooksEnv will never be called (as

      Convert cli.SubmitOpCode to use the master · 685ee993
      Iustin Pop authored
      This patch converts the cli.py SubmitOpCode method to use the unix
      protocol and thus execute the opcodes via the master.
      
      The patch allows a partial burnin to work with the master. Currently the
      query opcodes, since they are executed via the SubmitOpCode, are
      executed inside a job too, which is suboptimal, but they work fine.
      
      The cmd lock has been removed from the master, but the cli.py still
      takes the lock. This is ok for this in-progress patch (since the master
      still has only one executor thread). This will be fixed in a future
      patch.

      Move iallocator script execution to ganeti-noded · 8d528b7c
      Iustin Pop authored
      Currently the iallocator execution takes place in the master, which is a
      violation of the current architecture, and will create problems with a
      threaded master daemon.
      
      This patch moves the execution to the backend, similar to the hooks
      runner, by:
        - introducing a new class that handles the execution in the backend
          (and could be used also for listing the allocators, etc.)
        - introducing a new rpc call
        - replacing the actual execution in IAllocator.Run() with a rpc call
      
      This passes burnin with the dumb allocator

      Implement replace secondary via the iallocator · b6e82a65

      This patch implements secondary replace via the iallocator. The new
      opcode parameter 'iallocator' behaves like this: if passed, it will
      always compute and assign a new secondary, behaving in effect as if the
      secondary node has been passed. It conflicts with actually giving the
      secondary too.
      
      [Note: not tested with remote_raid1, but the code should behave the
      same, we only touch CheckPrereq and we assign a node.]
