Make intentions a tuple (to denote immutability)

2014-06-18T06:18:41+00:00

Since the atom intentions are not meant to be mutable
we should make sure that we create the object as a type
which is not mutable. This helps with those looking over
the code to understand its desired usage which is not to
be a mutable collection.

Upgrade hacking version and fix some of the issues

2014-06-14T02:27:17+00:00

Update hacking to the new requirements version and
fix about half of the new reported issues. The other
hacking issues are for now ignored until fixed by
adjusting our tox.ini file.

This commit fixes the following new hacking errors:

H405 - multi line docstring summary not separated
       with an empty line
E265 - block comment should start with '# '
F402 - import 'endpoint' from line 21 shadowed by
       loop variable

Implement run iterations

2014-05-07T21:41:17+00:00

Instead of blocking the caller when they call run()
allow there to be a new api run_iter() that will yield
back the engine state transitions while running. This
allows for a engine user to do alternate work while an
engine is running (and come back to yield on there own
time).

Implements blueprint iterable-execution

Reuse already defined variable

2014-04-14T17:05:58+00:00

The REVERTING variable is already defined as flow state. Reuse
it for the task state.

Merge "Move state link to developer docs"

2014-03-31T20:31:08+00:00

Move state link to developer docs

2014-03-30T03:16:30+00:00

The state wiki has been moved/deprecated and the
developer docs at http://docs.openstack.org/developer
are now the better source of this information.

Update the code to follow the new and improved link.

Adjust the exception hierachy

2014-03-25T03:42:30+00:00

Group the exceptions into the following groups
  * Storage
  * Jobs
  * Execution
  * Other (wrapped failure here)

This grouping makes it easier to understand where
one type of exception should be used vs using another
type of exception.

Backwards incompatible changes:
  * StorageError -> StorageFailure
  * AlreadyExists -> Duplicate
  * WrappedFailure now inherits from Exception
    and not directly from TaskFlowException since it
    wraps arbitrary other exceptions and is not
    specific to taskflow.

Cleanups:
  * JobNotFound -> NotFound
  * EmptyFlow -> Empty
  * JobAlreadyExists -> AlreadyExists
  * InvariantViolation (X)
  * ConnectionFailure (X)
