      Pass environment explicitly · 3fcf2f50
      Kamil Iskra authored
      When invoking 'argo_nodeos_config run', we were passing the job
      environment implicitly.  This wasn't very clean and was also causing
      problems with variables such as LD_PRELOAD, which were being filtered
      out because argo_nodeos_config is suid root.

      [feature] Use argo_nodeos_config --exec · edeb413b
      Swann Perarnau authored
      Use the new argo_nodeos_config --exec feature in development.
      Allow us to delegate fork+attach+exec to argo_nodeos_config, and
      simplifying the create command as a result.
      
      We use tornado.process to wrap this command, as we want to able to
      stream stdout/stderr in the future.
      
      This patch also misuse, the 'pid' field of the container namedtuple to
      save the tornado.process.Subprocess object itself, so some functions
      need to be adapted.

      [refactor] Use globally configured logger · b66c88ec
      Swann Perarnau authored
      The logging module allow us to configure logging facilities once per
      process using basicConfig, and then to use globally defined, named,
      logger objects. This simplifies access to logger objects, their
      configuration and remove pointers from all objects.
      
      This patch refactor all the logging calls to use a single 'nrm' logger
      object, using those facilities.

      [feature] Implement simple RM for containers · 1c4645cc
      Swann Perarnau authored
      This patch refactor the resource management and hwloc code into a
      working, albeit very simple scheduling policy. Indeed, the previous code
      contained strong assumptions about the output of hwloc matching an Argo
      NodeOS configuration used during the previous phase of the project, that
      always contained enough CPUs and Mems to perform exclusive scheduling.
      
      The current version is simpler, but should work on more regular systems.
      The patch also improves code organization so that introducing more
      complex scheduling algorithms will be simpler.
      
      The testing of this code resulted in the discovery of simple bugs in the
      daemon children handling code, which should work now.

      [feature] Pull the Argus code into the NRM · 92290b22
      Swann Perarnau authored
      The Argus (globalos) launcher had prototype code to read a container
      manifest, create a container using Judi's code, and map resources using
      hwloc.
      
      This patch brings that code, almost intact, into the NRM repo. This code
      is quite ugly, and the resource mapping crashes if the kernel
      configuration isn't right. But it's still a good starting point, and we
      should be able to improve things little by little.
      
      One part in particular needs attention: SIGCHLD handling. We should
      think of using ioloop-provided facilities to avoid this mess.
      
      The patch also contains the associated CLI changes.
      
      Note: the messaging format is starting to be difficult to keep in check,
      as there's conversions and field checks all over the code. See #3 for
      a possible solution.
