Flakey and Crap.py

These are just a couple of very short applications (scripts almost?) that I used for experimenting with temporal failure and retry modes. Keeping them around just for reference.

Crap.py

Run with python3. Don't forget to install flask. This just exposes a couple of http endpoints for tests. Apply the "@maybe" decorator to any of the functions to make it error some percentage of the time.

GET /

Returns a color:

{"color": <color>}

<color> is either "red" or "blue".

GET /color/

Returns a list of "steps".

{"steps": [<step>, ...]}

<step> is a string, e.g. "one"

GET /step/

Returns a "word" that equals whatever was passed in.

{"word": <step>}

POST /done

Accepts the following json:

{
    "color": <color>,
    "data": <data>
}

<color> is either "red" or "blue".
<data> is a string.

Returns nothing

If the data received is equal to the concatenated step strings associated with the color, it logs a successful entry. Otherwise it logs a failure.

Flakey

Flakey is a simple workflow that just calls all of the endpoints of Crap.py. Activities in the workflow are as follows:

• First, call / to get a color.
• Then call /color/<color> to get a list of steps.
• Call /step/<step> once for each step and concatenate the resulting strings.
• Post the results to /done.
