add akka-typed project with generic ActorRef This is the first step towards more type-safety in Actor interactions, comprising: * generic ActorRef[T] that only accepts T messages * generic ActorSystem[T] extends ActorRef[T] (sending to the guardian, whose Props[T] are provided for ActorSystem construction) * removed the Actor trait: everything in there has been made into messages and signals * new Behavior[T] abstraction that consumes messages (of type T) or Signals (lifecycle hooks, Terminated, ReceiveTimeout, Failed), producing the next Behavior[T] as the result each time * the ask pattern is provided and yields properly typed Futures * variants of ActorContext are provided for synchronous testing of Behaviors All of this is implemented without touching code outside akka-typed (apart from making guardianProps configurable), creating wrapper objects around ActorRef, ActorContext, ActorSystem, Props and providing an Actor implementation that just runs a Behavior. 2015-01-28 20:45:21 +01:00			`typed`

akka-persistence prototype The most prominent changes compared to eventsourced are: - No central processor and channel registry any more - Auto-recovery of processors on start and restart (can be disabled) - Recovery of processor networks doesn't require coordination - Explicit channel activation not needed any more - Message sequence numbers generated per processor (no gaps) - Sender references are journaled along with messages - Processors can determine their recovery status - No custom API on extension object, only messages - Journal created by extension from config, not by application - Applications only interact with processors and channels via messages - Internal design prepared for having processor-specific journal actors (for later optimization possibilities) Further additions and changes during review: - Allow processor implementation classes to use inherited stash - Channel support to resolve (potentially invalid) sender references - Logical intead of physical deletion of messages - Pinned dispatcher for LevelDB journal - Processor can handle failures during recovery - Message renamed to Persistent This prototype has the following limitations: - Serialization of persistent messages and their payload via JavaSerializer only (will be configurable later) - The LevelDB journal implementation based on a LevelDB Java port, not the native LevelDB (will be configurable later) The following features will be added later using separate tickets: - Snapshot-based recovery - Reliable channels - Journal plugin API - Optimizations - ... 2013-09-14 14:19:18 +02:00			`persistence`
