Allow choosing list of HTTP codes vaurien.behaviors.error.Error uses

[peritus]

First: Thanks for this monkey! Writing fault-tolerant services is fun again!

However:

https://github.com/mozilla-services/vaurien/blob/master/vaurien/behaviors/error.py

isn't particularly configurable or extension-friendly. I'd like to choose the list of http error codes (perhaps by subclassing the behavior).

BTW: Docs aren't telling me how to add a custom behaviour once I have written one. How do I tell the vaurien-command to Behavior.register() it ? Some entry_point magic ? Is there an example maybe ?

so long,

We're sending back a random http error from the 5xx list: https://github.com/mozilla-services/vaurien/blob/master/vaurien/behaviors/error.py#L89

but yeah, we could add an option to let the user pick one!

Docs aren't telling me how to add a custom behaviour once I have written one.

as shown here: https://vaurien.readthedocs.org/en/1.7/#using-vaurien-from-the-command-line

you can specify a --behavior option in the command line or the ini file

Thanks for the docs pointer!

My reasoning behind this is, I want to test a service that should behave differently for 502/503 (retry with exponential backoff) than for 500 (log the error, abort the job).

Yeah that makes total sense. If you're building a plugin derived from the http for this, we can merge it in the http one once it's ready
