Joshua Harlow 84b387f8bb Rework the in-memory backend 
This avoids storing direct copies of incoming objects and
makes sure that we always merge incoming objects (if a
saved object already exists) or create a copy of the
incoming object if it does not exist when storing.

On retrieval we also always return copies instead of
returning the data that is stored internally to avoid the
problems that can be hard to detect when users (engine
or other) modify those source objects.

Fixes bug 1365830

Also fixes a retry test case issue that was discovered due
to this more easily useable/understandable memory backend
changes...

TaskFlow

A library to do [jobs, tasks, flows] in a highly available, easy to understand and declarative manner (and more!) to be used with OpenStack and other projects.

Testing and requirements

Requirements

Because TaskFlow has many optional (pluggable) parts like persistence backends and engines, we decided to split our requirements into two parts: - things that are absolutely required by TaskFlow (you can't use TaskFlow without them) are put into requirements-pyN.txt (N being the Python major version number used to install the package); - things that are required by some optional part of TaskFlow (you can use TaskFlow without them) are put into optional-requirements.txt; if you want to use the feature in question, you should add that requirements to your project or environment; - as usual, things that required only for running tests are put into test-requirements.txt.

Tox.ini

Our tox.ini file describes several test environments that allow to test TaskFlow with different python versions and sets of requirements installed. Please refer to the tox documentation to understand how to make these test environments work for you.

Developer documentation

We also have sphinx documentation in docs/source.

To build it, run:

$ python setup.py build_sphinx
