Finagle v6.26.0 Release Notes

  • 🗄 Deprecations

    
* 🚚 finagle-memcached: Deprecated in favor of finagle-memcachedx and now removed.

🆕 New Features
    • 👍 finagle-httpx: Support nacks between Finagle Http clients and servers. When a server fails with retryable exceptions (exceptions wrapped by Failure.rejected), it sends back a "Nack" response, i.e. 503 Response code with a new "finagle-http-nack" header. This allows clients to safely retry failed requests, and keep connections open. RB_ID=670046

    💥 Breaking API Changes

    * 🚚 finagle-core: Moved netty3 specific things into a netty3 namespace. For
  these symbols, the namespace translation follows this pattern:
  `c.t.f.$MODULE._ => c.t.f.netty3.$MODULE._.` ``RB_ID=691746``

* finagle-core: Define `WeightedSocketAddress` as a case class. Add
  `WeightedSocketAddress.extract` method to extract weight. ``RB_ID=614228``

* finagle-core: Constructing a new Balancer that can be injected into a Finagle client
  was unnecessarily complex and non-uniform. We removed the legacy constructors around
  defining the collection of endpoints and simplified the interface to `LoadBalancerFactory`.
  Now, `com.twitter.finagle.loadbalancer.Balancers` defines the collection of balancer
  constructors. ``RB_ID=660730``

* 🔧 finagle-core: Aperture can no longer be enabled via command line flags. Configuring
  per-client settings globally is generally not a good idea and we're working to remove
  these flags from Finagle. Use the constructors in `com.twitter.finagle.loadbalancer.Balancers`
  to create an instance that can be injected into a client. ``RB_ID=663194``

* 0️⃣ finagle-core: The default load balancer has changed to p2c from heap. ``RB_ID=693450``

* finagle-core: `Service.isAvailable` and `ServiceFactory.isAvailable` is finalized.
  `Service.status` and `ServiceFactory.status` supersedes `isAvailable` usage since 6.24.0 release.
  ``RB_ID=678588``

* 🚚 finagle-core: `ClientBuilder.failureAccrual` method is removed. Use `ClientBuilder.failureAccrualFactory`
  instead. ``RB_ID=689076``

* 🚚 finagle-core: Stack param `ClientBuilder.ClientConfig.FailureAccrualFac` is removed.
  Use `ClientBuilder.failureAccrualFactory` instead. ``RB_ID=689076``

* 👻 finagle-exception: `com.twitter.finagle.exception.ExceptionReporter` is no longer used
  as the default `com.twitter.finagle.util.ReporterFactory`. ``RB_ID=674646``

* 📦 finagle-kestrel: Replace deprecated finagle-kestrel package with finagle-kestrelx.
  ``RB_ID=667920``

* finagle-core: Add new method `noFailureAccrual` on `ClientBuilder` that completely disables
  `FailureAccrualFactory` in the underlying stack. ``RB_ID=689076``
