Anastasia Karpinska 75eac61a06 Flow smart revert with retry controller 
- Remove flow REVERTING state. Now flow can be running and reverting simultaneously.
  Until flow isn't finished it is in RUNNING state.

- Add RETRYING state for the retry controller.

- Implement smart revertion and flow retries and retries resumption.

- Default retry controllers: Times, ForEach and ParameterizedForEach.

- Example and unit tests.

Implements: blueprint subgraph-execution
Implements: blueprint reversion-strategies
Implements: blueprint smart-revert

TaskFlow

A library to do [jobs, tasks, flows] in a HA manner using different backends to be used with OpenStack 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 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
