Runtime Behavior Changes

  • finagle-core: GenSerialClientDispatcher fails pending and subsequent requests when
    its underlying transport closes. RB_ID=807590

New Features

  • finagle-core: Include upstream/downstream addresses/client ids and request trace id
    in exceptions that extend c.t.f.HasRemoteInfo (including c.t.f.SourcedException),
    accessible via the remoteInfo value. RB_ID=797082
  • finagle-core: Introduce c.t.f.service.ResponseClassifier for HTTP servers,
    which allows developers to give Finagle the additional application specific knowledge
    necessary in order to properly classify responses.RB_ID=800179
  • finagle: Export two new histograms: request_payload_bytes and response_payload_bytes
    for the following protocols: HTTP (non-chunked), Mux, ThriftMux and Thrift. RB_ID=797821
  • finagle-core: Define c.t.f.Address to represent an endpoint's physical location.
    Resolvers and namers may attach metadata such as weight to individual endpoint addresses.
    RB_ID=792209
  • finagle-http: Introduce convenience extractors to pattern match c.t.f.http.Response.status
    against the different categories. RB_ID=802953
  • finagle-http: Add toBoolean method in StringUtil to parse strings to boolean consistently.
    RB_ID=804056

Breaking API Changes

  • finagle-core: c.t.f.Codec.prepareConnFactory(ServiceFactory) is marked final, override
    c.t.f.Codec.prepareConnFactory(ServiceFactory, Stack.Params) instead. RB_ID=797821

  • finagle-core: c.t.f.Codec.newClientDispatcher(Transport) is marked final, override
    c.t.f.Codec.newClientDispatcher(Transport, Stack.Params) instead. RB_ID=797821

  • finagle-core: Removed deprecations: RB_ID=800974

    • Removed c.t.f.Service.release, replace usage with Service.close().
    • Removed c.t.f.ServiceFactory.make, replace usage with ServiceFactory.apply.
    • Removed c.t.f.ProxyServiceFactory, replace usage with ServiceFactoryProxy.
    • Removed deprecated c.t.f.service.FailureAccrualFactory constructor.
    • Removed c.t.f.netty3.ChannelBufferBuf.apply, replace usage with ChannelBufferBuf.Owned.apply.
    • Removed c.t.f.util.InetAddressUtil.Loopback, replace usage with java.net.InetAddress.getLoopbackAddress.
    • Removed c.t.f.tracing.TracingFilter, replace usage with TraceInitializationFilter and (Client|Server)TracingFilter.

  • finagle-core: c.t.f.Addr.Bound.addr type changed from Set[SocketAddress] to
    Set[c.t.f.Address]. We provide a migration guide below for the most common cases.

    Callers of c.t.f.Addr.Bound.addr must handle Set[c.t.f.Address] instead of
    Set[SocketAddresses]. If you do something with the SocketAddress and expect the underlying
    type to be InetSocketAddress, use c.t.f.Address.Inet.addr to get the underlying
    InetSocketAddress.

    c.t.f.Addr constructors and c.t.f.Name.bound method now accept c.t.f.Address instead
    of SocketAddress. For most cases, wrapping the InetSocketAddress in an Address.Inet
    will fix the compile error.

    Any other SocketAddress subclass is currently incompatible with c.t.f.Address. Instead,
    you should encode any additional information in the metadata field of c.t.f.Address.Inet
    or c.t.f.exp.Address.ServiceFactory.

    RB_ID=792209

  • finagle-core: Delete c.t.f.ServiceFactorySocketAddress and replace usages with
    c.t.f.exp.Address.ServiceFactory. RB_ID=792209

  • finagle-core: Delete c.t.f.WeightedSocketAddress and instead use
    c.t.f.addr.WeightedAddress to represent address weights. RB_ID=792209

  • finagle-core: c.t.f.builder.ClientBuilder.hosts takes a Seq of InetSocketAddress instead of
    SocketAddress. If you get a compile error, change the static type to InetSocketAddress if
    you can. Otherwise, cast it at runtime to InetSocketAddress. RB_ID=792209

  • finagle-core: c.t.f.client.Transporter.EndpointAddr takes a c.t.f.Address as its
    parameter instead of SocketAddress. RB_ID=792209

  • finagle-core: c.t.f.service.FauilureAccrualFactory.Param(FailureAccrualPolicy) is removed -
    it's not safe to configure Failure Accrual with a shareable instance of the policy, use
    () => FailureAccrualPolicy instead. RB_ID=802953

  • finagle-core: $Client.withSessionQualifier.failureAccrualPolicy has been removed from the API
    since it enables an experimental feature (use Stack's .configured API instead). RB_ID=802953

  • finagle-core: c.t.f.service.exp.FailureAccrualPolicies (Java-friendly API) has bee removed -
    use c.t.f.service.exp.FailureAccrualPolicy instead.

  • finagle-memcached: c.t.f.memcached.protocol.text.Memcached no longer takes a StatsReceiver,
    pass it to a (Client/Server)Builder instead. RB_ID=797821

  • finagle-redis: c.t.f.redis.Redis no longer takes a StatsReceiver, pass it to a
    (Client/Server)Builder instead. RB_ID=797821
