Summary	0004454: fault injection for all GNU Taler APIs
Description	All HTTP endpoints that are not directly viewed in the browser should (via a configuration setting?) sometimes return one of the transient error code. Probably it is better to not implement this in the services directly, but in some layer between them and nginx. Having a non-zero probability of getting transient errors even for components that are completely functional forces us (and other developers) to write code that is resistant against these failures, by using appropriate error handling strategies.

Christian Grothoff 2018-03-27 15:32 manager ~0012908	The existence of Twister means that the fault injection logic is now in place. Details of using it (or enhancing it) will be separate bugs.
