  26a2c3bd

Breaking API Changes

• finagle-core: c.t.f.dispatch.ClientDispatcher.wrapWriteException has been turned from a
  partial function instance into a static total function. 9a3c9070

• finagle-mux: ClientDiscardedRequestException now extends FailureFlags and is no longer
  a case class. fe8c6496

Runtime Behavior Changes

• finagle-core: Server-side rejections from c.t.f.filter.RequestSempahoreFilter.module are now
  captured by c.t.f.service.StatsFilter. They will roll up under "/failures",
  "/failures/rejected", and "/failures/restartable" in stats. 3b755c8a

• finagle-core: c.t.f.tracing.Trace.tracers now returns only distinct tracers stored in
  the local context (returned all tracers before). b96bb137

• finagle-http: HTTP param decoding is no longer truncated to 1024 params.
  24662bea

• finagle-mux: When mux propagates an interrupt started by BackupRequestFilter over the
  network, the FailureFlags.Ignorable status is propagated with it. fe8c6496

Finagle 18.6.0

Runtime Behavior Changes

• finagle-core: By default, the deterministic aperture load balancer doesn't expand
  based on the loadband. This is because the loadband is influenced by a degree of
  randomness, and this breaks the deterministic part of deterministic aperture and
  can lead to aggressive banding on backends. 3d84e297

• finagle-http2: Unprocessed streams are retryable in case of GOAWAY.
  2c89cb9e

New Features

• finagle-core: Add PropagateDeadlines Stack.Param to TimeoutFilter for
  disabling propagation of deadlines to outbound requests.
  8041fbb9

• finagle-core: Add toString implementations to c.t.finagle.Service and
  c.t.finagle.Filter. Update in Filter#andThen composition to expose a
  useful toString for composed Filters and a composed Service (a Filter chain
  with a terminal Service or ServiceFactory).

  The default implementation for Filter and Service is getClass.getName. When
  composing filters, the andThen composition method correctly tracks the composed
  parts to produce a useful toString, e.g.,

  package com.foo

  import com.twitter.finagle.{Filter, Service}
  import com.twitter.util.Future

  class MyFilter1 extends Filter[Int, Int, Int, Int] {
     def apply(request: Int, service: Service[Int, Int]): Future[Int] = ???
  }

  ...

  package com.foo

  import com.twitter.finagle.{Filter, Service}
  import com.twitter.util.Future

  class MyFilter2 extends Filter[Int, Int, Int, Int] {
    def apply(request: Int, service: Service[Int, Int]): Future[Int] = ???
  }

  val filters = (new MyFilter1).andThen(new MyFilter2)

filters.toString would emit the String "com.foo.MyFilter1.andThen(com.foo.MyFilter2)"

If a Service (or ServiceFactory) were then added:

  import com.twitter.finagle.{Filter, Service}
  import com.twitter.finagle.service.ConstantService
  import com.twitter.util.Future

  ...

  val svc: Service[Int, Int] = filters.andThen(new ConstantService[Int, Int](Future.value(2)))

Then, svc.toString would thus return the String:
"com.foo.MyFilter1.andThen(com.foo.MyFilter2).andThen(com.twitter.finagle.service.ConstantService(ConstFuture(2)))"

Filter implementations are permitted to override their toString implementations which would
replace the default of getClass.getName. 25474da1

• finagle-core: Make Filter.TypeAgnostic an abstract class for Java usability.
  6534e459

• finagle-core: c.t.f.filter.NackAdmissionFilter is now public. 1855566d

  with javax.net.ssl.KeyManagerFactory and javax.net.ssl.TrustManagerFactory respectively.
  c863ca0b

Breaking API Changes

• finagle-core: Rename DeadlineFilter.Param(maxRejectFraction) to
  DeadlineFilter.MaxRejectFraction(maxRejectFraction) to reduce confusion
  when adding additional params.

Bug Fixes

• finagle-http2: StreamTransportFactory now marks itself as dead/closed when it runs out of
  HTTP/2 stream IDs instead of stalling. This allows the connection to be closed/reestablished in
  accordance with the spec c5554673

• finagle-netty4: SslServerSessionVerifier is now supplied with the proper peer address
  rather than Address.failing. 263e9786

• finagle-thrift/thriftmux: Disabled client side per-endpoint stats by default for client
  ServicePerEndpoint. It can be set via c.t.f.thrift.RichClientParam or a with-method
  as Thrift{Mux}.client.withPerEndpointStats. 0f1ff3eb

• finagle-netty4: Avoid NoClassDefFoundError if netty-transport-native-epoll is not available
  on the classpath. 940809af

• finagle-serversets: Zk2Session's AsyncSemaphore which controls the maximum
  concurrent Zk operations is configurable (GlobalFlag c.t.f.serverset2.zkConcurrentOperations).
  [3160a815](https://github.com/twitter/finagle/commit/3160a815c2552773a67d834841b029dca5ba0122)

  removed the need for the optimized c.t.f.Mux.Netty4RefCountingControl
  MuxImpl, which has been removed. 35980463

• finagle-mysql: c.t.f.mysql.Client.ping now returns a Future[Unit]
  instead of the broad Future[Result] ADT. 2f3650cf

• finagle-toggle: Changed ToggleMap.Mutable from a trait to an abstract class, and
  ToggleMap.Proxy no longer extends ToggleMap, but now has a self-type that conforms to
  ToggleMap instead. 16dbe170

Runtime Behavior Changes

• finagle-core: Add c.t.f.SslException to better model exceptions related to SSL/TLS.
  The c.t.f.ChannelException.apply method will now wrap javax.net.ssl.SSLExceptions in
  c.t.f.SslException. 955a0b3e

• finagle-core: MethodBuilder metrics now include failures.
  f58ab46f, f58ab46f

• finagle-http: ServerAdmissionControl is circumvented for HTTP requests that have
  a body unless the request contains the header 'finagle-http-retryable-request' since
  it cannot be known whether the client can actually retry them, potentially resulting
  in depressed success rates during periods of throttling. 4377f02a

• finagle-http2: Clients and servers no longer attempt a cleartext upgrade if the
  first request of the HTTP/1.1 session has a body. bf09dd4c

• finagle-thriftmux: The push-based client muxer is now the default muxer implementation.
  The push-based muxer has better performance and a simpler architecture. cc333151

  result in an infinite loop due to HashMap corruption. Access is now synchronized to avoid
  the infinite loop. aa73d24d

• finagle-core: FailureFlags that have their flags set modified will now
  retain the original stack trace, suppressed Throwables, and cause when possible.

  changed from 0 to -1. 61c7a711

• finagle-thrift: Move "stateless" methods in c.t.finagle.thrift.ThriftRichClient
  to c.t.finagle.thrift.ThriftClient. Then mix the ThriftClient trait into the
  ThriftMux and Thrift Client companions to make it clearer that these stateless methods
  are not affected by the changing state of the configured client instance but are instead
  simply utility methods which convert or wrap the incoming argument. 7a175a98

• finagle-base-http: With the intention to make c.t.f.http.Cookie immutable,
  set methods on c.t.f.http.Cookie have been deprecated:

  • comment_=
  • commentUrl_=
  • domain_=
  • maxAge_=
  • path_=
  • ports_=
  • value_=
  • version_=
  • httpOnly_=
  • isDiscard_=
  • isSecure_=

  Use the c.t.f.http.Cookie constructor to set domain, maxAge, path, value, httpOnly,
  and secure. comment, commentUrl, ports, version, and discard have been removed
  per RFC-6265. 71760096.

  Alternatively, use the domain, maxAge, path, httpOnly, and secure methods to create a
  new Cookie with the existing fields set, and the respective field set to a given value.

• finagle-base-http: c.t.f.http.Cookie.isSecure and c.t.f.http.Cookie.isDiscard
  have been deprecated. Use c.t.f.http.Cookie.secure for c.t.f.http.Cookie.isSecure.
  isDiscard has been removed per RFC-6265. 71760096

Breaking API Changes

• finagle-mysql: Moved Cursors.cursor method to Client trait, and removed Cursors trait.
  This allows cursor queries to used with transactions. 1224721c

• finagle-mux: Expose transport contexts in mux.Request and mux.Response. f0f46785

• finagle-mux: The "leased" gauge has been removed from the mux client implementation since the
  metric is reported as the sum of the value over all clients which is unlikely to be useful.
