* close #3173 - fixed issue with XUnit project packing * restored nuget command
* ported Chat sample to MSBUILD 15 * added back copyright header for ChatClient * set chat sample to run on .NET Core 1.1
* converted Akka.Cluster samples to MSBuild15 * rebased on ChatClient merge and fixed SLN file merge conflicts

Having maxSimultaneousRebalance > rebalanceThreshold in LeastShardAllocationStrategy caused shards "flapping" (deallocation of excessive shards followed by their immediate allocation on the same node)
* DDataShard + reorganized shard coordinators * DDataShardCoordinator * joined ddata cluster sharding * refactor of shard logic to trait-based * HOCON config for cluster-sharding ddata * working cluster sharding for both DData and Persistence * cluster-sharding DData replicator per role * fixed mntk tests * fixed GetState tests * replicated cluster-sharding mntk specs between persistent and ddata variants * fixed some of the mntk specs * fixed replicator for non-role settings * removed remember-entities from cluster sharding DData specs
ported from akka/akka#21306 closes 3222
Ask deadlock - proof of concept
- Address serilog colored console requirement. - Remove requirement for "SerilogLogMessageFormatter" as code examples appear to run without specifying the formatter. - Add an example of how an output template is configured for the extensions demo. - Remove use of serilog application configuration in code from the hocon example, but mention it as a feature of serilog.
* Cluster.JoinAsync / Cluster.JoinSeedNodesAsync * Cluster.JoinAsync: updated API approvals * added Cluster.JoinAsync exceptions * removed API approvals received.txt * added test cases for failure scenarios * added double checks for success/failure scenarios
* Fix exception that can occur when remaining and unreachable variables both have zero elements
Improve type safety for custom graph stages
If remaining and unreachable lists are empty an exception will be encountered as soon as .First() is executed to try to find the oldest node
Fixed weaklyup nodes stuck at joining

1.3.3 January 19 2019
Maintenance Release for Akka.NET 1.3
The largest changes featured in Akka.NET v1.3.3 are the introduction of Splint brain resolvers and
WeaklyUpmembers in Akka.Cluster.Akka.Cluster Split Brain Resolvers
Split brain resolvers are specialized
IDowningProviderimplementations that give Akka.Cluster users the ability to automatically downUnreachablecluster nodes in accordance with well-defined partition resolution strategies, namely:You can learn more about why you may want to use these and which strategy is right for you by reading our Splint brain resolver documentation.
Akka.Cluster
WeaklyUpMembersOne common problem that occurs in Akka.Cluster is that once a current member of the cluster becomes
Unreachable, the leader of the cluster isn't able to allow any new members of the cluster to join until thatUnreachablemember becomesReachableagain or is removed from the cluster via aCluster.Downcommand.Beginning in Akka.NET 1.3.3, you can allow nodes to still join and participate in the cluster even while other member nodes are unreachable by opting into the
WeaklyUpstatus for members. You can do this by setting the following in your HOCON configuration beginning in Akka.NET v1.3.3:This will allow nodes who have joined the cluster when at least one other member was unreachable to become functioning cluster members with a status of
WeaklyUp. If the unreachable members of the cluster are downed or become reachable again, allWeaklyUpnodes will be upgraded to the usualUpstatus for available cluster members.Akka.Cluster.Sharding and Akka.Cluster.DistributedData Integration
A new experimental feature we've added in Akka.NET v1.3.3 is the ability to fully decouple Akka.Cluster.Sharding from Akka.Persistence and instead run it on top of Akka.Cluster.DistributedData, our library for creating eventually consistent replicated data structures on top of Akka.Cluster.
Beginning in Akka.NET 1.3.3, you can set the following HOCON configuration option to have the
ShardingCoordinatorreplicate its shard placement state using DData instead of persisting it to storage via Akka.Persistence:This setting only affects how Akka.Cluster.Sharding's internal state is managed. If you're using Akka.Persistence with your own entity actors inside Akka.Cluster.Sharding, this change will have no impact on them.
