Rally v0.12.0

Release date

05/08/2018

Warning

It is friendly reminder about the future of in-tree OpenStack plugins. All further development is done in a separate project. In-tree plugins are deprecated and will be removed in next major release!

• Improve performance of rally task import command.

• Port internals of Verification component to support pip 10

• Extend plugins interface to provide config options to load. An example of setup.cfg/setup.py:

  Method list_opts in the above example, returns a dict where key is a category name, value is a list of options.

• Rework ResourceType plugin type. Previously, it was hard-coded for OpenStack resources only (initialization of OpenStack clients).

  An old interface looked like:

  from rally.common.plugin import plugin
  from rally.task import type
  
  @plugin.configure(name="glance")
  class GlanceResource(type.ResourceType):
      @classmethod
      def transform(cls, clients, resource_config):
          """Transform the resource config to id.
  
          :param clients: Initialized OpenStack clients
          :param resource_config: a dict with resource description
              taken from workload
          """
          pass
  

  The new one:

  from rally.common.plugin import plugin
  from rally.task import type
  
  @plugin.configure(name="glance")
  class GlanceResource(type.ResourceType):
      def __init__(self, context, cache=None):
          """init method
  
          :param context: A context object as like other plugins accept.
          :param cache: A global cache which can be used for listing
              the similar resources.
          """
          super(GlanceResource, self).__init__(context, cache)
          # NOTE #1: the next code is copy-pasted from
          #    *rally_openstack.types.OpenStackResourceType* class and
          #    there is no need to copy it to plugins itself, just inherit
          #    from the right parent.
          # NOTE #2: the following code is equal to what we have in
          #    an old ResourceType implementation. Property *self._clients*
          #    is what was transmitted to transform method as *clients*
          #    argument
          self._clients = None
          if self._context.get("admin"):
              self._clients = osclients.Clients(
                  self._context["admin"]["credential"])
          elif self._context.get("users"):
              self._clients = osclients.Clients(
                  self._context["users"][0]["credential"])
  
      def pre_process(self, resource_spec, config):
          """Pre process the resource config to id.
  
          :param resource_spec: a dict with resource description
              taken from workload
          :param config: A resource specification from scenario
              plugin. Usually it contains only *type* of resource.
          """
          #
          pass
  

Fixed bugs

• Fix deprecated –tasks argument of rally task report. Use –uuid instead.
• Fix printing warning of an old deprecated deployment configuration format.

Thanks

2 Everybody!
