  • Distributed Apps: The Joys of Testing and Debugging

    One tough problem in debugging distributed applications is understanding what happened on a client that later caused an exception on a server. I'll discuss the nature of Clojure stack traces and demonstrate a library that can extend a stack trace from where it was thrown, back across multiple thread or server boundaries to the client that initiated it. Even with more helpful stack traces, however, testing for the handling of race conditions is still very challenging. I'll demonstrate a technique that we've used at LonoCloud in our test suite to consistently reproduce and guard against race conditions.
