• Update asm, cglib, jmock dependencies 688cd29e

18.12.0

• scrooge-generator: Set a LocalContext value with the current Thrift method in the
  generated Java and Scala code such that the application Service[-R, +R] being executed has
  access to information about the current Thrift method being invoked. 09da3397

• scrooge-generator: Allow for Filter.TypeAgnostic filters to be applied to a generated
  Java Service via a new constructor that takes an additional argument of a Filter.TypeAgnostic.
  This filter is then applied per generated method service. 19c7d58b

• scrooge: Add type annotations to public members in generated code.
  5cad1005

• scrooge: Finally remove maven.twttr.com as a dependency or plugin repository. With
  the update to a more recent libthrift dependency, this should no longer be necessary.

18.9.0

New Features

• scrooge-generator: Scala and Java generated Thrift exceptions now
  implement c.t.f.FailureFlags. This allows exceptions to carry
  Finagle metadata such as non-retryable. 438599b0

18.8.0

• scrooge-core: Add interface for Scala generated Enum objects. c27d13ef

• scrooge-core: Trait c.t.scrooge.ThriftService is now c.t.finagle.thrift.ThriftServiceMarker.
  Scrooge generated service objects now all inherit from c.t.finagle.thrift.ThriftService. Also,
  the AsClosableMethodName string was formerly part of c.t.finagle.thrift.ThriftService, but
  now is defined in the c.t.scrooge package object.
  125e955e

• scrooge-generator: Thrift service objects now contain unsafeBuildFromMethods, which constructs
  a ReqRepServicePerEndpoint from a map of
  ThriftMethod -> ThriftMethod.ReqRepServicePerEndpointServiceType. It is unsafe because the
  types are not checked upon service construction, only when a request is attempted.

• scrooge-adaptive: Turn the scrooge-adaptive back on as default in ScroogeRunner. 633e0f26

No Changes

• scrooge-generator: Add cocoa initializer for each field in union. 904f5981

• scrooge-generator: Add support for empty struct in cocoa. 2c9dcde2

• scrooge-generator: Fix setter bug for non-primitive type in cocoa. 04d654fc

• scrooge-adaptive: Turn the scrooge-adaptive off as default in ScroogeRunner due to

• scrooge-generator: Add support for construction_required fields. Add a validateNewInstance method
  to all generated scala companion objects. cbde3312

• scrooge-core: Check for corruption in size meta field of container and throw
  an exception if size is found corrupted. 75392161

• scrooge: Upgrade libthrift to 0.10.0. 997f2464

• scrooge-generator: Add support for mutually recursive structs. 2a731bbc

• scrooge-generator: Add asClosable method to ServicePerEndpoint and
  ReqRepServicePerEndpoint interfaces as well. 597864ac

• scrooge-generator: Remove unused functionToService and serviceToFunction
  methods along with ServiceType and ReqRepServiceType type aliases in
  order to simplify code generation.

  NOTE: This functionality can be manually replicated by users if/when needed
  to convert between a Function1 and a Finagle Service. 2d25eb25

• scrooge-generator: Scala generated client now has a asClosable method returns c.t.u.Closable,
  client now can be closed by calling client.asClosable.close. Note that asClosable won't be
  generated if it is also defined by the user. 1fa4f0c6

• scrooge-generator: Renamed subclasses of com.twitter.scrooge.RichResponse:
  ProtocolExceptionResponse, SuccessfulResponse, and ThriftExceptionResponse.
  These case classes are for representing different response types and should be only
  used by the generated code. 2194e77d

• scrooge-generator: Update c.t.fingale.thrit.service.MethodPerEndpointBuilder
  to build MethodPerEndpoint types. Add new ThriftServiceBuilder for
  building the higher-kinded form from a ServicePerEndpoint. Users should
  prefer using the MethodPerEndpointBuilder. PHAB_ID=D127538

• scrooge-generator: Add more metadata to generated java objects PHAB_ID=D122997
  Includes:

  • struct and field annotations from the idl files
  • which fields have default values
  • which field values of TType.STRING are actually binary fields

• scrooge: Add support for scrooge.Request and scrooge.Response
  types in generated ThriftMethod code. PHAB_ID=D122767

• scrooge: Introduce scrooge.Request and scrooge.Response envelopes which
  are used in ReqRepServicePerEndpoint interfaces and associated code. The
  scrooge Request and Response allow for passing "header" information (via
  ThriftMux Message contexts) between clients and servers. For instance, a
  server can implement a ReqRepServicePerEndpoint, and set response headers
  along with a method response, e.g.,

  class MyService extends MyService.ReqRepServicePerEndpoint {
  
    def foo: Service[Request[Foo.Args], Response[Foo.SuccessType]] = {
      Service.mk[Request[Foo.Args], Response[Foo.SuccessType]] { request: Request[Foo.Args] =>
        val result = ... // computations
        Future
          .value(
            Response(
              headers = Map("myservice.foo.header" -> Seq(Buf.Utf8("value1"))),
              result)
      }
    }
  }
  

  This ServicePerEndpoint can then be served using ThriftMux:

  ThriftMux.server.serveIface(":9999", new MyService().toThriftService)
  

  These response headers will be transported as Mux#contexts to the client. If
  the client is using the client-side ReqRepServicePerEndpoint it will be able
  to read the headers from the returned Response directly. E.g.,

  val client = ThriftMux.client.reqRepServicePerEndpoint[MyService.ReqRepServicePerEndpoint]
  
  val response: Response[Foo.SuccessType] = Await.result(client.foo(..))
  
  if (response.headers.contains("myservice.foo.header")) {
    ...
  

  Users can also choose to wrap the ReqRepServicePerEndpoint with a MethodPerEndpoint
  via ThriftMux.client.reqRepMethodPerEndpoint(reqRepServicePerEndpoint) in order to
  deal with methods instead of services. See the scrooge documentation for more information.

• scrooge-generator: Deprecated some scala generated classes and use new ones
  FutureIface -> MethodPerEndpoint,
  MethodIface -> MethodPerEndpoint.apply(),
  MethodIfaceBuilder -> MethodPerEndpointBuilder,
  BaseServiceIface -> ServicePerEndpoint,
  ServiceIface -> ServicePerEndpoint,
  ServiceIfaceBuilder -> ServicePerEndpointBuilder.
  To construct a client use c.t.f.ThriftRichClient.servicePerEndpoint instead of
  newServiceIface, to convert ServicePerEndpoint to MethodPerEndpoint use
  c.t.f.ThriftRichClient.methodPerEndpoint instead of newMethodIface. 26f86b2b

• scrooge-generator: (BREAKING API CHANGE) Change the java generator to no longer
  generate files with org.slf4j imports and remove limited usage of org.slf4j
  Logger in generated services. bf5364be

• From now on, release versions will be based on release date in the format of
  YY.MM.x where x is a patch number. 2645da60

• scrooge-generator: For generated scala $FinagleService, moved per-endpoint statsFilter to the
  outermost of filter chain so it can capture all exceptions, added per-endpoint response
  classification in statsFilter. 853323dc

• scrooge-generator: Generated scala $FinagleClient takes a RichClientParam for all
  configuration params, such as TProtocolFactory, ResponseClassifier, maxReusableBufferSize,
  and StatsReceiver, $FinagleService takes a RichServerParam. 8bdf36cb

Updated dependencies to Finagle 7.1.0 and Util 7.1.0

• scrooge-generator: Generated scala/java code now is using serviceMap instead of functionMap
  for Finagle services' method implementation. PHAB_ID=D73619 for scala and
  PHAB_ID=D76129 for java

• scrooge-generator: Generated Java code now is using c.t.s.TReusableBuffer to reduce
  object allocations. This in turn adds scrooge-core as dependency for generated
  java code. PHAB_ID=D60406

• scrooge-generator: Support for thrift struct field doccomments for scala
  generated code RB_ID=918179

• scrooge-generator: The MethodIface in generated Scala code implements
  FutureIface. It already "was" that type in practice but did not implement
  that trait. PHAB_ID=D67289

• scrooge-generator: Generated Cocoa code now supports modular frameworks and
  removes some compiler warnings about implicit casts. PHAB_ID=D74200
