Util 19.3.0

New Features

• util-core: Discard parent reader from Reader.flatten
  when child reader encounters an exception. 0cc640ac
• util-core: Added c.t.conversions.StringOps\#toSnakeCase,toCamelCase,toPascalCase
  implementations. b0a5d062

Util 19.2.0

New Features

• util-core: updated Reader#fromFuture to resolve its onClose when reading of end-of-stream.
  f2a05474
• util-core: Added Reader.flatten to flatten a Reader[Reader[_]] to Reader[_],
  and Reader.fromSeq to create a new Reader from a Seq. a49bab4d
• util-core: Added Duration.fromMinutes to return a Duration from a given number of minutes.
  eda0b390
• util-core: If given a Timer upon construction, c.t.io.Pipe will respect the close
  deadline and wait the given amount of time for any pending writes to be read. 0a142872
• util-core: Optimized ConstFuture.proxyTo which brings the performance of
  flatMap and transform of a ConstFuture in line with map. de4cebda
• util-core: Experimental toggle (com.twitter.util.BypassScheduler) for speeding up
  ConstFuture.map (transformTry). The mechanism, when turned on, runs map operations
  immediately (why not when we have a concrete value), instead of via the Scheduler, where it may
  be queued and potentially reordered, e.g.:
  f.flatMap { _ => println(1); g.map { _ => println(2) }; println(3) } will print 1 2 3,
  where it would have printed 1 3 2. aeafba1a
• util-security: Pkcs8KeyManagerFactory now supports a certificates file which contains multiple
  certificates that are part of the same certificate chain. 337e270f

Bug Fixes

• util-core: Fixed the behavior in c.t.io.Reader where Reader#flatMap fails to propagate
  parent reader's onClose. f2a05474

Runtime Behavior Changes

• util-core: Closing a c.t.io.Pipe will notify onClose when the deadline has passed whereas
  before the pipe would wait indefinitely for a read before transitioning to the Closed state.
  0a142872
• util-core: Don't allow AsyncSemaphore Permits to be released multiple times. Before it was
  possible to release a permit more than once and incorrectly remove waiters from the queue.
  With this change, the release permit operation is idempotent. ea24c951

Breaking API Changes

• util-core: Remove c.t.u.CountDownLatch which is an extremely thin shim around
  j.u.c.CountDownLatch that provides pretty limited value. To migrate to j.u.c.CountDownLatch,
  instead of c.t.u.CountDownLatch#await(Duration), please use
  j.u.c.CountDownLatch#await(int, TimeUnit), and instead of
  c.t.u.CountDownLatch#within(Duration), please throw an exception yourself after awaiting.

• util-core: Deprecated conversions in c.t.conversions have new implementations
  that follow a naming scheme of SomethingOps. df397f53
  • percent is now PercentOps
  • storage is now StorageUnitOps
  • string is now StringOps
  • thread is now ThreadOps
  • time is now DurationOps
  • u64 is now U64Ops
• util-collection: Delete util-collection. We deleted GenerationalQueue, MapToSetAdapter, and
  ImmutableLRU, because we found that they were of little utility. We deleted LruMap because it
  was a very thin shim around a j.u.LinkedHashMap, where you override removeEldestEntry. If you
  need SynchronizedLruMap, you can wrap your LinkedHashMap with
  j.u.Collection.synchronizedMap. We moved RecordSchema into finagle-base-http because it was
  basically only used for HTTP messages, so its new package name is c.t.f.http.collection.

• util-core: Rename BlacklistStatsReceiver to DenylistStatsReceiver. ed3f7069
• util-core: Buf.Composite is now private. Program against more generic, Buf interface instead.

Util 19.1.0

New Features

• util-core: Added Reader.map/flatMap to transform Reader[A] to Reader[B]. Added fromFuture()
  and value() in the Reader object to construct a new Reader. ac15ad8b

Breaking API Changes

• util-core: The implicit conversions classes in c.t.conversions.SomethingOps have been
  renamed to have unique names. This allows them to be used together with wildcard imports.
  See Github issue (#239). 2d5d6da9
• util-core: Both c.t.io.Writer.FailingWriter and c.t.io.Writer.fail were removed. Build your
  own instance should you need to. 63815225

Util 18.12.0

18.12.0

New Features

• util-core: Provide a way to listen for stream termination to c.t.util.Reader, Reader#onClose
  which is satisfied when the stream is discarded or read until the end. 3b1434e2
• util-core: Conversions in c.t.conversions have new implementations
  that follow a naming scheme of SomethingOps. Where possible the implementations
  are AnyVal based avoiding allocations for the common usage pattern.
  ee56e5f2
  • percent is now PercentOps
  • storage is now StorageUnitOps
  • string is now StringOps
  • thread is now ThreadOps
  • time is now DurationOps
  • u64 is now U64Ops

Bug Fixes

• util-core: Fixed a bug where tail would sometimes return Some empty AsyncStream instead of None.
  1dc614bc

Deprecations

• util-core: Conversions in c.t.conversions have been deprecated in favor of SomethingOps
  versions. Where possible the implementations are AnyVal based and use implicit classes
  instead of implicit conversions. ee56e5f2
  • percent is now PercentOps
  • storage is now StorageUnitOps
  • string is now StringOps
  • thread is now ThreadOps
  • time is now DurationOps
  • u64 is now U64Ops

Breaking API Changes

• util-core: Experimental c.t.io.exp.MinThroughput utilities were removed. d9c5e4a3
• util-core: Deleted c.t.io.Reader.Null, which was incompatible with Reader#onClose semantics.
  c.t.io.Reader#empty[Nothing] is a drop-in replacement. 3b1434e2
• util-core: Removed c.t.util.U64 bits. Use c.t.converters.u64._ instead. 8034e557

Util 18.11.0

Breaking API Changes

• util-core: c.t.u.Future.raiseWithin methods now take the timeout exception as a call-by-name
  parameter instead of a strict exception. While Scala programs should compile as usual, Java
  users will need to use a scala.Function0 as the second parameter. The helper
  c.t.u.Function.func0 can be helpful. 9bde57ca
• util-core: Rename c.t.io.Reader.ReaderDiscarded to c.t.io.ReaderDiscardedException.
  a970c5b5

Runtime Behavior Changes

• util-core: Made Stopwatch.timeNanos monotone. 8d35b496

Util 18.10.0

Breaking API Changes

• util-core: c.t.io.Reader.Writable and c.t.Reader.writable() are removed. Use c.t.io.Pipe
  instead. 5ef6a0dc

• util-core: c.t.util.TempFolder has been moved to c.t.io.TempFolder. 2f8ee904

• util-core: Removed the forwarding types c.t.util.TimeConversions and
  c.t.util.StorageUnitConversions. Use c.t.conversions.time and
  c.t.conversions.storage directly. 0c83ebc0

• util-core: c.t.concurrent.AsyncStream.fromReader has been moved to
  c.t.io.Reader.toAsyncStream. 6c3be47d

New Features

• util-core: c.t.io.Reader.fromBuf (BufReader), c.t.io.Reader.fromFile,
  c.t.io.Reader.fromInputStream (InputStreamReader) now take an additional parameter,
  chunkSize, the upper bound of the number of bytes that a given reader emits at each read.
  719f41a6

Runtime Behavior Changes

• util-core: c.t.u.Duration.inTimeUnit can now return
  j.u.c.TimeUnit.MINUTES. 0daac8d7

Util 18.9.1

Breaking API Changes

• util-core: c.t.io.Writer now extends c.t.util.Closable. c.t.io.Writer.ClosableWriter
  is no longer exist. 9cc7025c

Bug Fixes

• util-slf4j-api: Moved slf4j-simple dependency to be a 'test' dependency, instead of a
  compile dependency, which was inaccurate. 3d6d7457

Util 18.9.0

18.9.0

New Features

• util-logging: New way to construct ScribeHandler for java interoperability.
  845620b4
• util-core: Added Reader#fromAsyncStream for consuming an AsyncStream as a Reader.
  39ec9849
• util-core: Introducing Reader.chunked that chunks the output of a given reader.
  1a7c54f9

  SSLSessions. 12de479f

Breaking API Changes

• util-core: c.t.io.Reader and c.t.io.Writer are now abstracted over the type
  they produce/consume (Reader[A] and Writer[A]) and are no longer fixed to Buf.
  7718fa29

• util-core: InMemoryStatsReceiver now eagerly creates the mappings for Counters
  and Stats instead of waiting for the first call to Counter.incr and Stat.add.
  97f0f0fa

• util-core: c.t.io.Reader.Writable is now c.t.io.Pipe. Both Writable type and
  its factory method are deprecated; use new Pipe[A] instead. cbff9760

• util-slf4j-api: Ensure that marker information is used when determining if log
  level is enabled for methods which support markers. 02d80820

• util-slfj4-api: Finalize the underlying logger def in the Logging trait as it is not
  expected that this be overridable. If users wish to change how the underlying logger is
  constructed they should simply use the Logger and its methods directly rather than
  configuring the the underlying logger of the Logging trait.

  Add better Java compatibility for constructing a Logger. 56569b9f

Util 18.8.0

18.8.0 2018-08-06

Bug Fixes:

• util-core: Fixed an issue with Future.joinWith where it waits for
  completion of both futures even if one has failed. This also affects
  the join method, which is implemented in terms of joinWith. 9b598f3f

Util 18.7.0

API Changes

• util-core: Local.Context used to be a type alias for Array[Option[_]], now it is
  a new key-value liked structure. faaf0f2f
