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... Change-Id: I2afdda7beb71e35f7e12d9fd7ccf90b6c5447274

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
