Finagle v22.7.0 Release Notes

    • finagle-thrift: Changing visibility of InputBuffer and OutputBuffer from [finagle] to [twitter]. PHAB_ID=D938475

    🆕 New Features

    * 🔧 finagle-core: Introduce panic mode in load balancers. Configure the threshold for
  panic mode to start using `withLoadBalancer.panicMode`. ``PHAB_ID=D879034``

* finagle-core: Provide `ServerParamsInjector`, a class that will be service-loaded at run-time
  by Finagle servers, and will allow generic configuration of all sets of parameters.
  ``PHAB_ID=D897484``

* finagle-memcached: Add new function, `newLoadBalancedTwemcacheClient`, to create a TwemcacheClient
  that doesn't use a partitioning service.
  ``PHAB_ID=D911789`

🐛 Bug Fixes
    • finagle-core: fix issue where Trace.traceLocal and Trace.traceLocalFuture nested traces mistakenly annotate to the parent span. PHAB_ID=D912760

    💥 Breaking API Changes

    
* 🚚 finagle-core: Remove unused `DeterministicAperture` along with pathways to use weight-unaware 
  aperture loadbalancers. ``PHAB_ID=D933405``

* finagle-base-http: Methods for getting/setting `Accept`, `Authorization`, `Host`, `Referer`,
  `User-Agent`, `X-Forwarded-For` headers were moved from `c.t.f.http.Message` class to
  `c.t.f.http.Request` as these headers are only valid on requests and not on responses.
  Methods for getting/setting `Location`, `Retry-After`, `Server`, and `WWW-Authenticate` headers
  were moved from `c.t.f.http.Message` class to `c.t.f.http.Response` as they are only valid
  on responses and not on requests.

* ⚡️ finagle-core: Update OffloadFilter.Param API to encourage recommended construction.
  ``PHAB_ID=D882210``

* finagle-core: `Trace.recordLocalSpan` is `private[this]` and no longer `protected`. ``PHAB_ID=D912760``

* finagle-core: "ServiceFactory#status" is abstract and requires implementation in the inherited
  classes. ``PHAB_ID=D933288``

* finagle-core: `StackTransformer` has been renamed to `ServerStackTransformer` and the symmetric
  client equivalent (`ClientStackTransformer`) has been added. For those using the older `StackTransformer`
  API you will both need to change the code (fix the extends) __and__ rename the META-INF file from
  `resources/META-INF/services/com.twitter.finagle.StackTransformer` to
  `resources/META-INF/services/com.twitter.finagle.ServerStackTransformer` in order to have your
  transformer continue to service-load correctly. ``PHAB_ID=D937634``
