Moshe Elisha commented on TOSCA-207:
------------------------------------

The possibilities are:

1. Leave things as they are:

tosca.interfaces.node.lifecycle.Standard:
  create
  configure
  start
  postconfigure
  stop
  delete

This makes the "postconfigure" operation name confusing as according to the docs it runs after the "start" operation and not after the "configure" operation.

2. Rename the operation to "post_start":

tosca.interfaces.node.lifecycle.Standard:
  create
  configure
  start
  post_start (was postconfigure)
  stop
  delete

This makes the name a lot more clearer but I don't see a real value here if the "post_start" always runs after the "start" and there is no way to intervene. The user can just place the content of the "post_start" in the "start".

3. I propose to leave it "post_configure" but run it between the "post_configure" and the "start":

tosca.interfaces.node.lifecycle.Standard:
  create
  configure
  post_configure
  start
  stop
  delete

This has value in case the node has a relationship. In that case the order (on a certain node) will be:

  Standard.create
  Configure.pre_configure_[source/target]
  Standard.configure
  Configure.post_configure_[source/target]
  Standard.post_configure
  Standard.start
  Standard.stop
  Standard.delete

This allows the user to have one more point to manipulate the deploy time execution.
I think this has the most value.

> That will be much more clear (simple if it was called poststart as this is actually a poststart operation).
