* The scenario was that previous leader left. * The problem was that the new leader got MemberRemoved before it got the HandOverDone and therefore missed the hand over data. * Solved by not changing the singleton to leader when receiving MemberRemoved and instead do that on normal HandOverDone or in failure cases after retry timeout. * The reason for this bug was the new transition from Down to Removed and that there is now no MemberDowned event. Previously this was only triggered by MemberDowned (not MemberRemoved) and that was safe because that was "always" preceeded by unreachable. * The new solution means that it will take longer for new singleton to startup in case of unreachable previous leader, but I don't want to trigger it on MemberUnreachable because it might in the future be possible to switch it back to reachable. |

h1. Akka We believe that writing correct concurrent, fault-tolerant and scalable applications is too hard. Most of the time it's because we are using the wrong tools and the wrong level of abstraction. Akka is here to change that. Using the Actor Model together with Software Transactional Memory we raise the abstraction level and provide a better platform to build correct concurrent and scalable applications. For fault-tolerance we adopt the "Let it crash" model which the telecom industry has used with great success to build applications that self-heal and systems that never stop. Actors also provide the abstraction for transparent distribution and the basis for truly scalable and fault-tolerant applications. Akka is Open Source and available under the Apache 2 License.
