22.12.0

New Features

• scrooge-core: c.t.scrooge.StructBuilder.forStructClass API for retrieving
  the StructBuilder for a struct or union class that helps in building ThriftStruct. PHAB_ID=D934277

Breaking API Changes

• scrooge-generator: c.t.scrooge.ast.Field.hasValidationAnnotation field can no longer
  be set in the constructor, but it is now a property derived from the value in the
  Field.fieldAnnotations field; if any annotations have a name starting with validation.
  it is set to true, otherwise it is false. PHAB_ID=D912077

Runtime Behavior Changes

• scrooge-generator: Move ServerValidationMixin trait to be in the companion object of the service, this is to
  avoid ambiguities when calling the trait from inherited services. PHAB_ID=D943975
• scrooge-thrift-validation: custom annotations in ThriftValidator must have a
  name starting with validation. PHAB_ID=D912077
• scrooge-generator: Checks for reference equality in Scala structs before iterating over the fields, this is to
  reduce the cost of equals checks on large structs (many fields or deeply nested fields). PHAB_ID=D950010
• scrooge: Use the util-mock for testing which depends on the 3.12.4 "org.mockito", remove the
  "org.jmock" dependencies. 967d7ddf
• scrooge: c.t.scrooge.StructBuilder now accepts null values for non-primitive default-required fields. e35e1842

22.7.0

New Features

• scrooge-generator: Introduce a AnnotatedFieldType to abstract type annotations from
  FieldType definitions. Currently used to propagate thrift annotations inside of
  collection types. 59e91e64 2fa68351
• scrooge-core: c.t.scrooge.ThriftUnion.fieldInfoForUnionClass API for retrieving
  ThriftStructFieldInfo for a ThriftUnion member class without having to instantiate
  it. 19809c22
• scrooge-generator: Add @.generated annotation to Swift generated code 8fd6a089
• scrooge-generator: Provide a $STRUCT#unsetFields method to allow bulk unsets aef5029b
• scrooge-generator: support thrift validations on nested fields that are struct, union, and
  exception 8bad4dd7

22.4.0

No Changes

22.3.0

New Features

• scrooge-generator: for each method defined in a service in the Thrift IDL, if any request arg
  of a method has annotations started with validation., in Java template, generate a new trait
  ServerValidationMixin with a new API violationReturning<method_name> which validates incoming
  request (of Struct, Union, Exception types) and return any violations (as method parameters
  <request_variable>Violations) back to the users in the method API. aab91465

Breaking API Changes

• scrooge: ThriftUnion is now defined to extend ThriftStruct. In practice,
  this is not a significant change as all Scrooge-generated classes that
  implement ThriftUnion also implement ThriftStruct. We just made the
  invariant that unions are always structs explicit in the type system.

Runtime Behavior Changes

• scrooge: Bump version of Jackson to 2.13.2. b283d341

22.2.0

New Features

• scrooge-core: c.t.scrooge.ThriftStructCodec.forStructClassTag API for retrieving
  the codec for a struct or union class given a class tag or manifest and
  c.t.scrooge.ThriftStructMetadata.forStructClassTag for retrieving its metadata.
  ba1a97bc
• scrooge-core: c.t.scrooge.ThriftStructCodec.forStructClass API for retrieving codec
  for a struct or union class and c.t.scrooge.ThriftStructMetadata.forStructClass for
  similarly retrieving its metadata. PHAB_ID=_D825675
• scrooge-generator: for each method defined in a service in the Thrift IDL, if any request arg
  of a method has annotations started with validation., generate a new trait
  ServerValidationMixin with a new API violationReturning<method_name> which validates incoming
  request (of Struct, Union, Exception types) and return any violations (as method parameters
  <request_variable>Violations) back to the users in the method API. aa83a3f5

Breaking API Changes

• scrooge-generator: the c.t.scrooge.frontend.ThriftParser now always throws exceptions
  rather than warnings when a fieldname matches a reserved keyword. See
  c.t.scrooge.frontend.ThriftKeywords for the full list of disallowed
  keywords. 33767856

No Changes

21.12.0

No Changes

21.11.0

Runtime Behavior Changes

• scrooge-serializer: concrete implementations of the ThriftStructSerializer
  trait in the c.t.scrooge. package now cache the value of its maxReusableBufferSize
  flag for the duration of the application. This improves performance but also makes them
  not observe changes to the flag. The value of this flag typically does not change during
  run time of an application, so this is deemed an acceptable tradeoff. 064e1535

21.10.0

No Changes

Breaking API Changes

• scrooge-generator: Dropped the generic (higher-kinded-types) service interface in scala-gen,
  users are recommended to use YourService.MethodPerEndpoint, YourService.ServicePerEndpoint
  and YourService.ReqRepServicePerEndpoint to represent Thrift service endpoints. Note,
  -finagle option is required to generated finagle binding code. 8d768ca6

• scrooge-generator: Removed YourService.FutureIface and YourService[Future] in scala-gen,
  use $YourService.MethodPerEndpoint instead. Correspondingly, YourService$FinagleService and
  related constructors taking MethodPerEndpoint as parameters. 8d768ca6

• Scrooge-generator: Dropped ThriftServiceBuilder.build and MethodIfaceBuilder.newMethodIface.
  8d768ca6

• scrooge-generator: Add reserved keywords to ThriftParser. If your field names match
  these keywords, you may need to modify them. This change should not affect backwards
  and forwards compatiblility if using binary protocol for serde. 884f3603

Runtime Behavior Changes

• scrooge: Update ScalaCheck to version 1.15.4. scrooge-sbt-plugin and
  scrooge-generator still use the older version 1.14.3 because they compile
  with Scala 2.10. ad063665

No Changes

• scrooge-generator: Modify struct field names when they match Java keywords by adding
  an underscore prefix to the field name. a33de276

No Changes but the version update

Runtime Behavior Changes

• scrooge: Revert to scala version 2.12.12 due to https://github.com/scoverage/sbt-scoverage/issues/319
  e67edc0c
• scrooge: Bump scala version to 2.12.13 3864106d

Breaking API Changes

• scrooge: Builds are now only supported for Scala 2.12+ 72f5a0a0

No Changes

• scrooge: Scrooge uses better size estimate for Map/Set containers in read()
  to improve performance in Java. b1ebce81

20.12.0

New Features

• finagle-core: Add a new stat (histogram) that reports how long a task has been sitting in the
  offload queue. This instrumentation is sampled at the given interval (100ms by default) that
  can be overridden with a global flag com.twitter.finagle.offload.statsSampleInterval.
  a7ebf2e1
• finagle-core: Add a new experimental flag com.twitter.finagle.offload.queueSize that allows to
  put bounds on the offload queue. Any excess work that can't be offloaded due to a queue overflow
  is run on IO (Netty) thread instead. Put this way, this flag enables the simplest form of
  backpressure on the link between Netty and OffloadFilter. af228ca6
• finagle-netty4: Add ExternalClientEngineFactory to the open source version of Finagle. This
  SslClientEngineFactory acts as a better example of how to build custom client and server engine
  factories in order to reuse SSL contexts for performance concerns. 931785d9
• finagle-core: Provide com.twitter.finagle.naming.DisplayBoundName for configuring how to
  display the bound Name for a given client in metrics metadata. 67be8e1e
• finagle-core: Provide ClientParamsInjector, a class that will be service-loaded at run-time
  by Finagle clients, and will allow generic configuration of all sets of parameters.
  b7bb5afc

Breaking API Changes

• finagle-core: Move DarkTrafficFilter and AbstractDarkTrafficFilter from the experimental
  finagle-exp to supported finagle-core. The package containing these classes changed from
  c.t.finagle.exp to c.t.finagle.filter. 0ecaa5e7
• finagle-core, finagle-thrift: Move ForwardingWarmUpFilter and ThriftForwardingWarmUpFilter
  from the experimental finagle-exp to supported finagle-core, and finagle-thrift, respectively.
  The package containing ForwardingWarmUpFilter changed from c.t.finagle.exp to
  c.t.finagle.filter, and the package containing ThriftForwardingWarmUpFilter changed from
  c.t.finagle.exp to c.t.finagle.thrift.filter. e725bc86
• finagle-core: FailureAccrualFactory.isSuccess has been replaced with the method
  def classify(ReqRep): ResponseClass to allow expressing that a failure should be ignored.
  d586bd24

Runtime Behavior Changes

• finagle-core: Use Scala default implementation to calculate Hashcode and equals method for
  ServiceFactoryProxy. c473b395
• finagle: Update build.sbt to get aarch64 binaries and try the fast path acquire up to 5 times
  before failing over to the AbstractQueuedSynchronizer slow path in NonReentrantReadWriteLock
  for Arm64. d45dfb02

Bug Fixes

• finagle-core: Users should no longer see the problematic
  java.lang.UnsupportedOperationException: tail of empty stream when a c.t.f.s.RetryPolicy
  is converted to a String for showing. e7ec247d
