- Instead of formatting the exception by creating a storage error instance we can just let the already included cause make this formatting occur. - Handle cases in impl_dir which were not catching and raising storage errors. - Unify usage of 'backend internal error' messaging. - Pass the cause to storage errors where applicable.

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 to
requirements.txt; - things that are required by some optional part of TaskFlow (you
can use TaskFlow without them) are put to
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
to
test-requirements.txt.
Tox.ini
Our tox.ini describes several test environments that allow to test TaskFlow with different python versions and sets of requirements installed.
To generate tox.ini, use the toxgen.py script by first installing
toxgen and then provide that script
as input the tox-tmpl.ini file to generate the final tox.ini file.
For example:
$ toxgen.py -i tox-tmpl.ini -o tox.ini
