dotnet/orleans v1.5.0-beta1

on GitHub

Improvements and bug fixes since 1.4.1.

• Breaking changes
  • Upgraded minimum framework dependency to .NET 4.6.1 #2945
  • Support for non-static client via ClientBuilder (although static GrainClient still works but will be removed in a future version). You can now start many clients in the same process, even if you are inside a Silo #2822.
    There are a few differences though:
    • Several changes to SerializationManager, mainly to make it non-static #2592
      • When deserializing a GrainReference from storage, you might need to re-bind it to the runtime by calling grain.BindGrainReference(grainFactory) on it or you would get GrainReferenceNotBoundException when attempting to use it #2738
      • Removed RegisterSerializerAttribute (and corresponding static Register method for registering a custom serializer). If you were using that, please read https://dotnet.github.io/orleans/Documentation/Advanced-Concepts/Serialization.html#writing-custom-serializers for alternative ways to register your custom serializer #2941
  • Better serialization of Type values (but can cause compatibility issues if these were persisted by using the Serialization Manager) #2952
  • Automatically deactivate a grain if it bubbles up InconsistentStateException (thrown when there is an optimistic concurrency conflict when writing to storage) #2959
  • Providers are now constructed using Dependency Injection. The result is that custom providers must have a single public constructor with either no arguments or arguments which can all be injected, or they need to be explicitly registered in the ServiceCollection. #2721 #2980
  • Change default stream subscription faulting to false in EventHub and Memory stream providers, as is in other providers #2974
  • Bug fix: Azure storage providers now throw InconsistenStateException instead of StorageException when eTags do not match #2971
• Non-breaking improvements
  • Grain interface versioning to enable no-downtime upgrades #2837 2837
  • Programmable stream subscribe API #2741 #2796 #2909
  • Support for custom placement strategies and directors #2932
  • Improvements to GrainServices API #2839
  • Replace CallContext.LogicalSetData with AsyncLocal #2200 #2961
  • Ability to configure FabricClient when deploying to Service Fabric #2954
  • Added extension points to EventHubAdapterFactory #2930
  • Added SlowConsumingPressureMonitor for EventHub streams #2873
  • Dispose all registered services in the container when shutting down #2876
  • Try to prevent port collisions when starting in-memory TestCluster #2779
  • Deprecated TestingSiloHost in favor of TestCluster (although the former is still available for this version) #2919
• Non-breaking bug fixes
  • Change how message expiration is handled to account for server clock skew #2922
  • Several minor bug fixes and perf improvements, as well as reliability in our test code
