Note that PHAB_ID=# and RB_ID=# correspond to associated messages in commits.
- util: Bump version of Jackson to 2.14.2.
PHAB_ID=D1049772
- util-core: Introduce Future.fromCompletableFuture
PHAB_ID=D940686 - util-core: Introduce Time.fromInstant
PHAB_ID=D987464 - util-core: Introduce TimeFormatter, a replacement for TimeFormat. TimeFormatter uses
the modern java.time.format.DateTimeFormatter API instead of the java.text.SimpleDateFormat
with the main advantage being that it doesn't require synchronization on either formatting or
parsing, and is thus more performant and causes no contention.
PHAB_ID=D987464 - util-stats: MetricBuilder now has API to configure a format in which histograms are exported.
Use .withHistogramFormat to access it.
PHAB_ID=D908189
- util-core: TimeFormat, as well as the Time.format methods are deprecated in favor of using
TimeFormatter.
PHAB_ID=D987464
- util: Bump version of Jackson to 2.14.1.
PHAB_ID=D1025778 - util-core: Time.at, Time.toString, and Time.fromRss now use TimeFormatter internally and
thus have better performance and do not cause contention through synchronization. toString always
uses TimeFormatter while at and fromRss only use it when run with Java 9 or later due to a
compatibility bug in Java 1.8.
PHAB_ID=D987464
- util-stats: SourceRole subtypes have been moved into the SourceRole object to make their
relationship to the parent type more clear.
PHAB_ID=D909744
- util-jackson: Update Jackson library to version 2.13.3
PHAB_ID=D906005 - util-jackson: Deserialized case classes with validation on optional fields shouldn't throw an error.
PHAB_ID=D915377 - util: Update snakeyaml to 1.28
PHAB_ID=D930268
- util-stats: The metric instantiation methods have been removed from MetricBuilder. Use the methods on
StatsReceiver to instantiate metrics instead.
PHAB_ID=D859036
- util-stats: Deprecated methods on MetricBuilder for directly instantiating metrics so that we can
eventually remove the statsReceiever field from MetricBuilder and let it just be the source of
truth for defining a metric.
PHAB_ID=D862244
- util-core: Added Memoize.classValue as a Scala-friendly API for java.lang.ClassValue.
PHAB_ID=D825673 - util-jvm: Register JVM expression including memory pool usages (including code cache, compressed class space,
eden space, sheap, metaspace, survivor space, and old gen) and open file descriptors count in StatsReceiver.
PHAB_ID=D820472 - util-slf4j-jul-bridge: Add Slf4jBridge trait which can be mixed into extensions of c.t.app.App in
order to attempt installation of the SLF4JBridgeHandler via the Slf4jBridgeUtility in the constructor
of the c.t.app.App instance.
PHAB_ID=D827493
- util: Bump version of Jackson to 2.13.2.
PHAB_ID=D848592 - util-slf4j-api: Update the Logger API to include "call-by-name" method
variations akin to the Logging trait. When creating a Logger from a
Scala singleton object class, the resultant logger name will no longer include
the $ suffix. Remove the deprecated Loggers object which is no longer
needed for Java compatibility as users can now directly use the Logger
apply functions with no additional ceremony.
PHAB_ID=D820252 - util: Bump version of Caffeine to 2.9.3.
PHAB_ID=D815761
- util-core: The c.t.util.Responder trait has been removed.
PHAB_ID=D824830
- util-jackson: The error message when failing to deserialize a character now correctly prints the non-character string.
PHAB_ID=D808049
- util: Bump version of Jackson to 2.13.1.
PHAB_ID=D808049 - util-core: Return suppressed exception information in Closable.sequence
PHAB_ID=D809561
- util-core: Activity.collect* and Var.collect* are now implemented in terms of known collection
type scala.collection.Seq versus HKT CC[X] before. This allows for certain performance
enhancements as well as makes it more aligned with the Future.collect APIs.
PHAB_ID=D795123
- util-security: Use snakeyaml to parse yaml instead of a buggy custom yaml
parser. This means that thrown IOExceptions have been replaced by
YAMLExceptions. Additionally, the parser member has been limited to private visibility.
PHAB_ID=D617641
- util-security: Any valid yaml / json file with string keys and values can
be loaded with com.twitter.util.security.Credentials.
PHAB_ID=D617641
- util-cache: Update Caffeine cache library to version 2.9.2
PHAB_ID=D771893 - util-jackson: Enable BLOCK_UNSAFE_POLYMORPHIC_BASE_TYPES in ScalaObjectMapper to
guard against Remote Code Execution (RCE) security vulnerability. This blocks
polymorphic deserialization from unsafe base types.
PHAB_ID=D780863
- util-core: Add convenience methods to convert to java.time.ZonedDateTime and
java.time.OffsetDateTime. toInstant, toZonedDateTime, and toOffsetDateTime also preserve
nanosecond resolution.
PHAB_ID=D757636 - util-stats: Moved c.t.finagle.stats.LoadedStatsReceiver and c.t.finagle.stats.DefaultStatsReceiver
from the finagle-core module to util-stats.
PHAB_ID=D763497 - util-jvm: Update exported metric schemas to properly reflect their underlying counter types
PHAB_ID=D710019
- util-jvm: Experimentally crossbuilds with Scala 3.
PHAB_ID=D728602 - util-stats: Counter, Gauge, and Stat can be instrumented with descriptions.
PHAB_ID = D615481 - util-cache: Experimentally crossbuilds with Scala 3.
PHAB_ID=D714304. - util-cache-guava: Experimentally crossbuilds with Scala 3.
PHAB_ID=D716101. - util-routing: Experimentally crossbuilds with Scala 3.
PHAB_ID=D727120 - util-sl4j-api: Experimentally crossbuilds with Scala 3.
PHAB_ID=D725491 - util-sl4j-jul-bridge: Experimentally crossbuilds with Scala 3.
PHAB_ID=D726468 - util-stats: Experimentally crossbuilds with Scala 3.
PHAB_ID=D720514 - util-zk-test: Experimentally crossbuilds with Scala 3.
PHAB_ID=D720603 - util-app: Flags parsing will now roll-up multiple flag parsing errors into a single
error message. When an error is encountered, flag parsing will continue to collect parse error
information instead of escaping on the first flag failure. After parsing all flags, if any errors
are present, a message containing all of the failed flags and their error reason,
along with the help usage message will be emitted.
`PHAB_ID=D729700
- util: Bump version of Jackson to 2.11.4.
PHAB_ID=D727879 - util: Bump version of json4s to 3.6.11.
PHAB_ID=D729764
- util-app: the c.t.app.App#flags field is now a final def instead of a val to address override val scenarios where the c.t.app.App#flags are accessed as part of construction, resulting in a NullPointerException due to access ordering issues. The c.t.app.Flags class is now made final. The c.t.app.App#name field has changed from a val and is now a def. A new c.t.app.App#includeGlobalFlags def has been exposed, which defaults to true. The c.t.app#includeGlobalFlags def can be overridden to false (ex: override protected def includeGlobalFlags: Boolean = false) in order to skip discovery of GlobalFlag`s during flag parsing. ```PHAB_ID=D723956`
- util-stats: add getAllExpressionsWithLabel utility to InMemoryStatsReceiver.
PHAB_ID=D722942
- util-app: Experimentally crossbuilds with Scala 3.
PHAB_ID=D714780 - util-app-lifecycle: Experimentally crossbuilds with Scala 3.
PHAB_ID=D716444 - util-codec: Experimentally crossbuilds with Scala 3.
PHAB_ID=D715114 - util-hashing: Experimentally crossbuilds with Scala 3.
PHAB_ID=D718914 - util-lint: Experimentally crossbuilds with Scala 3.
PHAB_ID=D698954 - util-registry: Experimentally crossbuilds with Scala 3.
PHAB_ID=D716019 - util-thrift: Experimentally crossbuilds with Scala 3.
PHAB_ID=D715129 - util-app: Introduce a new Command class which provides a Reader interface to the output
of a shell command.
PHAB_ID=D686134 - util-core: Experimentally crossbuilds with Scala 3.
PHAB_ID=D694775
- util-app: Flags and GlobalFlag now use ClassTag instead of Manifest.
PHAB_ID=D714780 - util-thrift: ThriftCodec now uses ClassTag instead of Manifest. In
scala3 Manifest is intended for use by the compiler and should not be used in
client code.
PHAB_ID=D715129 - util-core (BREAKING): Remove AbstractSpool. Java users should use Spools static class or
the Spool companion object to create instances of Spool.
PHAB_ID=D694775
- util: Update ScalaCheck to version 1.15.4
PHAB_ID=D691691 - util-jackson: JsonDiff#toSortedString now includes null-type nodes, so that
JsonDiff.Result#toString shows differences in objects due to such nodes.
PHAB_ID=D707033
util-core: Add ClasspathResource, a utility for loading classpath resources as an optional InputStream.
PHAB_ID=D687324util-jackson: Add com.twitter.util.jackson.YAML for YAML serde operations with a default configured ScalaObjectMapper. Add more methods to com.twitter.util.jackson.JSON
PHAB_ID=D687327util-jackson: Introduce a new library for JSON serialization and deserialization based on the Jackson integration in Finatra.
This includes a custom case class deserializer which "fails slow" to collect all mapping failures for error reporting. This deserializer is also natively integrated with the util-validator library to provide for performing case class validations during deserialization.
PHAB_ID=D664962
- util-stats: Removed MetricSchema trait (CounterSchema, GaugeSchema and HistogramSchema).
StatReceiver derived classes use MetricBuilder directly to create counters, gauges and stats.
PHAB_ID=D668739
- util-cache: Update Caffeine cache library to version 2.9.1
PHAB_ID=D660908
- util-validator: Introduce new library for case class validations (akin to Java bean validation)
which follows the Jakarta Bean Validation specification (https://beanvalidation.org/) by wrapping
the Hibernate Validator library and thus supports jakarta.validation.Constraint annotations and
validators for annotating and validating fields of Scala case classes.
PHAB_ID=D638603 - util-app: Introduce a Java-friendly API c.t.app.App#runOnExit(Runnable) and
c.t.app.App#runOnExitLast(Runnable) to allow Java 8 users to call c.t.app.App#runOnExit
and c.t.app.App#runOnExitLast with lambda expressions.
PHAB_ID=D511536
- util-reflect: Memoize c.t.util.reflect.Types#isCaseClass computation.
PHAB_ID=D657748
- util-stats: Added a methods c.t.f.stats.Counter#metadata: Metadata,
c.t.f.stats.Stat#metadata: Metadata, and c.t.f.stats.Gauge#metadata:
Metadata to make it easier to introspect the constructed metric. In
particular, this will enable constructing Expression`s based on the full name
of the metric. If you don't have access to a concrete `Metadata instance
(like MetricBuilder) for constructing a Counter, Stat, or Gauge, you can
instead supply NoMetadata.
PHAB_ID=D653751
- util-stats: Added a com.twitter.finagle.stats.Metadata abstraction, that can
be either many com.twitter.finagle.stats.Metadata, a MetricBuilder, or a
NoMetadata, which is the null Metadata. This enabled constructing
metadata for counters that represent multiple counters under the hood.
PHAB_ID=D653751
- util: Revert to scala version 2.12.12 due to scoverage/sbt-scoverage#319
PHAB_ID=D635917 - util: Bump scala version to 2.12.13
PHAB_ID=D632567
- util: Rename c.t.util.reflect.Annotations#annotationEquals to c.t.util.reflect.Annotations#equals
and c.t.util.reflect.Types.eq to c.t.util.reflect.Types.equals.
PHAB_ID=D640386 - util: Builds are now only supported for Scala 2.12+
PHAB_ID=D631091 - util-reflect: Remove deprecated c.t.util.reflect.Proxy. There is no library replacement.
PHAB_ID=D630143 - util-security: Renamed com.twitter.util.security.PemFile to c.t.u.security.PemBytes, and
changed its constructor to accept a string and a name. The main change here is that we assume
the PEM-encoded text has been fully buffered. To migrate, please use the helper method on the
companion object, PemBytes#fromFile. Note that unlike before with construction, we read from
the file, so it's possible for it to throw.
PHAB_ID=D641088 - util-security: Make KeyManager, TrustManager Factory helper methods public. The main change here
is that we expose util methods that are used to generate TrustManagerFactory, KeyManagerFactory
inside c.t.u.security for public usage.
PHAB_ID=D644502
- util-reflect: Add c.t.util.reflect.Annotations a utility for finding annotations on a class and
c.t.util.reflect.Classes which has a utility for obtaining the simpleName of a given class
across JDK versions and while handling mangled names (those with non-supported Java identifier
characters). Also add utilities to determine if a given class is a case class in
c.t.util.reflect.Types.
PHAB_ID=D638655 - util-reflect: Add c.t.util.reflect.Types, a utility for some limited reflection based
operations.
PHAB_ID=D631819 - util-core: c.t.io now supports creating and deconstructing unsigned 128-bit buffers
in Buf.
PHAB_ID=D606905 - util-core: c.t.io.ProxyByteReader and c.t.io.ProxyByteWriter are now public. They are
useful for wrapping an existing ByteReader or ByteWriter and extending its functionality
without modifying the underlying instance.
PHAB_ID=D622705 - util-core: Provided c.t.u.security.X509CertificateDeserializer to make it possible to directly
deserialize an X509Certificate even if you don't have a file on disk. Also provided
c.t.u.security.X509TrustManagerFactory#buildTrustManager to make it possible to directly
construct an X509TrustManager with an X509Certificate instead of passing in a File.
PHAB_ID=D641088
No Changes
No Changes
- util-core: removed com.twitter.util.Config.
PHAB_ID=D580444 - util-core: removed com.twitter.util.Future.isDone method. The semantics of this method
are surprising in that Future.exception(throwable).isDone == false. Replace usages with
Future.isDefined or Future.poll
PHAB_ID=D585700 - util-stats: Changed com.twitter.finagle.stats.MethodBuilder#withName,
com.twitter.finagle.stats.MethodBuilder#withRelativeName,
com.twitter.finagle.stats.MethodBuilder#withPercentiles,
com.twitter.finagle.stats.MethodBuilder#counter, and
com.twitter.finagle.stats.MethodBuilder#histogram, to accept varargs as parameters,
rather than a Seq. Added a Java-friendly com.twitter.finagle.stats.MethodBuilder#gauge.
PHAB_ID=D620425
- util-core: c.t.conversions now includes conversion methods for maps (under MapOps)
that were moved from Finatra.
PHAB_ID=D578819 - util-core: c.t.conversions now includes conversion methods for tuples (under TupleOps)
that were moved from Finatra.
PHAB_ID=D578804 - util-core: c.t.conversions now includes conversion methods for seqs (under SeqOps)
that were moved from Finatra.
PHAB_ID=D578605 - util-core: c.t.conversions now includes conversion methods toOption, and getOrElse
under StringOps.
PHAB_ID=D578549 - util-core: c.t.util.Duration now includes fromJava and asJava conversions to
java.time.Duration types.
PHAB_ID=D571885
- util-core: Activity.apply(Event) will now propagate registry events to the underlying
Event instead of registering once and deregistering on garbage collection. This means
that if the underlying Event is "notified" while the derived Activity is not actively
being observed, it will not pick up the notification. Furthermore, the derived Activity
will revert to the Activity.Pending state while it is not under observation.
PHAB_ID=D574843 - util-core: Activity#stabilize will now propagate registry events to the underlying
Activity instead of registering once and deregistering on garbage collection. This means
that if the underlying Activity is changed to a new state while the derived Activity is not actively
being observed, it will not update its own state. The derived Activity will maintain its last
"stable" state when it's next observed, unless the underlying Activity was updated to a new "stable"
state, in which case it will pick that up instead.
PHAB_ID=D574843 - util-stats: c.t.finagle.stats.DenylistStatsReceiver now includes methods for creating
DenyListStatsReceiver from partial functions.
PHAB_ID=D576833 - util-core: c.t.util.FuturePool now supports exporting the number of its pending tasks via
numPendingTasks.
PHAB_ID=D583030
- util-stat: MetricBuilder now uses a configurable metadataScopeSeparator to align
more closely with the metrics.json api. Services with an overridden scopeSeparator will
now see that reflected in metric_metadata.json where previously it was erroneously using
/ in all cases.
PHAB_ID=D557994 - util-slf4j-api: Better Java interop. Deprecate c.t.util.logging.Loggers as Java users should be
able to use the c.t.util.logging.Logger companion object with less verbosity required.
PHAB_ID=D558605
- util-app: Seq/Tuple2/Map flags can now operate on booleans. For example,
Flag[Seq[Boolean]] now works as expected instead of throwing an assert exception (previous
behaviour).
PHAB_ID=D549196
- util-app: Flaggable.mandatory now takes implicit ClassTag[T] as an argument. This is change is
source-compatible in Scala but requires Java users to pass argument explicitly via
ClassTag$.MODULE$.apply(clazz).
PHAB_ID=D542135
- util: Bump version of Jackson to 2.11.2.
PHAB_ID=D538440
- util-mock: Introduce mockito-scala based mocking
integration. Fix up and update mockito testing dependencies:
- mockito-all:1.10.19 to mockito-core:3.3.3
- scalatestplus:mockito-1-10:3.1.0.0 to scalatestplus:mockito-3-2:3.1.2.0
PHAB_ID=D530995 - util-app: Add support for flags of Java Enum types.
PHAB_ID=D530205
- util-stats: Store MetricSchemas in InMemoryStatsReceiver to enable further testing.
PHAB_ID=D518195 - util-core: c.t.u.Var.Observer is now public. This allows scala users to extend the Var trait
as has been the case for Java users.
PHAB_ID=D520237 - util-core: Added two new methods to c.t.u.Duration and c.t.u.Time: .fromHours and .fromDays.
PHAB_ID=D522734
- util-app: Treat empty strings as empty collections in Flag[Seq[_]], Flag[Set[_]],
Flag[java.util.List[_]], and Flag[java.util.Set[_]]. They were treated as collections
with single element, empty string, before.
PHAB_ID=D516724
- util-app: Add ability to observe App lifecycle events.
PHAB_ID=D508145
- util-stats: Add two new Java-friendly methods to StatsReceiver (addGauge and provideGauge)
that take java.util.function.Supplier as well as list vararg argument last to enable better
developers' experience.
PHAB_ID=D497885 - util-app: Add a Flaggable instance for java.time.LocalTime.
PHAB_ID=D499606 - util-app: Add two new methods to retrieve flag's unparsed value (as string): Flag.getUnparsed
and Flag.getWithDefaultUnparsed.
PHAB_ID=D499628
- util-security: Moved Credentials from util-core
c.t.util.Credentials => c.t.util.security.Credentials.
PHAB_ID=D477984
- util-core: Move Credentials to util-security
c.t.util.Credentials => c.t.util.security.Credentials.
PHAB_ID=D477984util-core: Change the namespace of ActivitySource and its derivatives to com.twitter.io as its no longer considered experimental since the code has changed minimally in the past 5 years.
PHAB_ID=D478498
- util-tunable: ConfigurationLinter accepts a relative path.
PHAB_ID=D468528
- util: Bump jackson version to 2.11.0.
PHAB_ID=D457496
- util-core: When looking to add idempotent close behavior, users should mix in CloseOnce to
classes which already extend (or implement) Closable, as mixing in ClosableOnce leads to
compiler errors. ClosableOnce.of can still be used to create a ClosableOnce proxy of an
already instantiated Closable. Classes which do not extend Closable can still
mix in ClosableOnce.
PHAB_ID=D455819
- util-hashing: Rename
c.t.hashing.KetamaNode => HashNode, c.t.hashing.KetamaDistributor => ConsistentHashingDistributor.
PHAB_ID=D449929
- util-stats: Provide CachedRegex, a function that filters a
Map[String, Number] => Map[String, Number] and caches which keys to filter on
based on a regex. Useful for filtering down metrics in the style that Finagle
typically recommends
PHAB_ID=D459391.
- util-core: The system property com.twitter.util.UseLocalInInterruptible no longer
can be used to modulate which Local state is present when a Promise is interrupted.
PHAB_ID=D442444
- util-core: Promises now exclusively use the state local to setting the interrupt
handler when raising on a Promise.
PHAB_ID=D442444
- util-app: Add c.t.util.app.App#onExitLast to be able to provide better Java
ergonomics for designating a final exit function.
PHAB_ID=D433874 - util-core: Add c.t.io.Reader.concat to conveniently concatenate a collection
of Reader to a single Reader.
PHAB_ID=D434448
- util-core: Future.unapply has been removed. Use Future.poll to retrieve Future's
state.
PHAB_ID=D427429
- util-logging: Add a missing _* that could result in exceptions when using the
Logger.apply(Level, Throwable, String, Any*) signature.
PHAB_ID=D430122
No Changes
- util-stats: Introduces c.t.f.stats.LazyStatsReceiver which ensures that counters and histograms don't export metrics until after they have been incr`ed or `add`ed at least once. ``PHAB_ID=D398898`
- util-core: Introduce Time#nowNanoPrecision to produce nanosecond resolution timestamps in JDK9
or later.
PHAB_ID=D400661 - util-core: Introduce Future#toCompletableFuture, which derives a CompletableFuture from
a com.twitter.util.Future to make integrating with Java APIs simpler.
PHAB_ID=D408656
- util: Upgrade to jackson 2.9.10 and jackson-databind 2.9.10.1
PHAB_ID=D410846
- util-core: The lightly used com.twitter.util.JavaSingleton trait has been removed. It
did not work as intended. Users should provide Java friendly objects, classes, and methods
instead.
PHAB_ID=D399947
- util-test: The c.t.logging.TestLogging mixin has been deprecated. Users are encouraged to
move to slf4j for logging and minimize dependencies on com.twitter.logging in general, as
it is intended to be replaced entirely by slf4j.
PHAB_ID=D403574
- util-core: Future#toJavaFuture incorrectly threw the exception responsible for failing it,
instead of a j.u.c.ExecutionException wrapping the exception responsible for failing it.
PHAB_ID=D408656
- util: Add initial support for JDK 11 compatibility.
PHAB_ID=D365075 - util-core: Created public method Closable.stopCollectClosablesThread that stops CollectClosables
thread. PHAB_ID=D382800
- util-core: Introduced Reader.fromIterator to create a Reader from an iterator. It is not
recommended to call iterator.next() after creating a Reader from it. Doing so will affect the
behavior of Reader.read() because it will skip the value returned from iterator.next.
PHAB_ID=D391769
- util: Upgrade to caffeine 2.8.0
PHAB_ID=D384592 - util-jvm: Stop double-exporting postGC stats under both jvm and jvm/mem. These are now
only exported under jvm/mem/postGC.
PHAB_ID=D392230
- util-stats: abstract methods of StatsReceiver now take Schemas. The old APIs are now final and cannot be overriden. For custom implementations, define schema based methods (eg, counter(verbosity, name) is now counter(CounterSchema)). NB: users can continue to call the old interface; only implementors must migrate.``PHAB_ID=D385068``
- util-core: Removed c.t.io.Pipe.copyMany (was Reader.copyMany). Use AsyncStream.foreachF
link to Pipe.copy for substitution.
PHAB_ID=D396590 - util-core: Add c.t.io.BufReader.readAll to consume a Reader[Buf] and concat values to a Buf.
Replace c.t.io.Reader.readAll with Reader.readAllItems, the new API consumes a generic Reader[T],
and return a Seq of items.
PHAB_ID=D391346 - util-core: Moved c.t.io.Reader.chunked to c.t.io.BufReader.chunked, and Reader.framed to
BufReader.framed.
PHAB_ID=D392198 - util-core: Moved c.t.io.Reader.copy to c.t.io.Pipe.copy, and Reader.copyMany to
Pipe.copyMany.
PHAB_ID=D393650
- util-core: Mark c.t.io.BufReaders, c.t.io.Bufs, c.t.io.Readers, and c.t.io.Writers as
Deprecated. These classes will no longer be needed, and will be removed, after 2.11 support is
dropped.
PHAB_ID=D393913 - util-stats: Removed deprecated methods stat0 and counter0 from StatsReceiver.
PHAB_ID=D393063
- util-core: When a computation from FuturePool is interrupted, its promise is
set to the interrupt, wrapped in a j.u.c.CancellationException. This wrapper
was introduced because, all interrupts were once CancellationExceptions. In
RB_ID=98612, this changed to allow the user to raise specific exceptions as
interrupts, and in the aid of compatibility, we wrapped this raised exception
in a CancellationException. This change removes the wrapper and fails the
promise directly with the raised exception. This will affect users that
explicitly handle CancellationException.
PHAB_ID=D371872
- util-core: Fixed bug in c.t.io.Reader.framed where if the framer didn't emit a List the
emitted frames were skipped.
PHAB_ID=D378048 - util-hashing: Fix a bug where partitionIdForHash was returning incosistent values w.r.t
entryForHash in KetamaDistributor.
PHAB_ID=D381128
- util-app: Better handling of exceptions when awaiting on the c.t.app.App to close at the end of the main function. We Await.ready on this as the last step of App#nonExitingMain which can potentially throw a TimeoutException which was previously unhandled. We have updated the logic to ensure that TimeoutException`s are handled accordingly. ``PHAB_ID=D356846`
- util: Upgrade to Scala Collections Compat 2.1.2.
PHAB_ID=D364013
- util-core: BoundedStack is unused and really old code. Delete it.
PHAB_ID=D357338 - util-logging: com.twitter.logging.ScribeHandler and com.twitter.logging.ScribeHandlers have
been removed. Users are encouraged to use slf4j for logging. However, if a util-logging integrated
ScribeHandler is still required, users can either build their own Finagle-based scribe client as
in ScribeRawZipkinTracer in finagle-zipkin-scribe, or copy the old ScribeHandler
implementation directly into their code.
PHAB_ID=D357008
- util: Enables cross-build for 2.13.0.
PHAB_ID=D333021
- util-stats: In c.t.finagle.stats.AbstractStatsReceiver, the counter, stat and
addGauge become final, override counterImpl, statImpl and addGaugeImpl instead.
PHAB_ID=D333021 - util-core:
- c.t.concurrent.Offer.choose,
c.t.concurrent.AsyncStream.apply,
c.t.util.Await.all,
c.t.util.Closable.sequence become available to java for passing varargs.
PHAB_ID=D333021
- util-stats:
- c.t.finagle.stats.StatsReceiver.provideGauge and addGauge become available to java for
passing varags.
PHAB_ID=D333021
- util-core: (not breaking) c.t.util.Future.join and c.t.util.Future.collect now take
Iterable[Future[A]] other than Seq.
PHAB_ID=D333021 - util-core: Revert the change above, in c.t.util.Future, collect, collectToTry and join
take scala.collection.Seq[Future[A]].
PHAB_ID=D355403 - util-core: com.twitter.util.Event#build now builds a Seq of events. Event#buildAny builds
against any collection of events.
PHAB_ID=D333021
- util-logging: The namespace forwarders for Level and Policy in com.twitter.logging.config
have been removed. Code should be updated to use com.twitter.logging.Level and
com.twitter.logging.Policy where necessary. Users are encouraged to use 'util-slf4j-api' though
where possible.
PHAB_ID=D344439 - util-logging: The deprecated com.twitter.logging.config.LoggerConfig and associated
classes have been removed. These have been deprecated since 2012. Code should be updated
to use com.twitter.logging.LoggerFactory where necessary. Users are encouraged to use
'util-slf4j-api' though where possible.
PHAB_ID=D345381
- util: Upgrade to Jackson 2.9.9.
PHAB_ID=D345969 - util-app: It is now illegal to define GlobalFlags enclosed in package objects.
PHAB_ID=D353045
- util-core: Removed deprecated c.t.concurrent.Scheduler methods usrTime,
cpuTime, and wallTime. These were deprecated in 2015 and have no
replacement.
PHAB_ID=D330386 - util-core: Removed deprecated com.twitter.logging.config classes SyslogFormatterConfig,
ThrottledHandlerConfig, SyslogHandlerConfig. These were deprecated in 2012 and have
no replacement. Users are encouraged to use 'util-slf4j-api' where possible.
PHAB_ID=D339563
- util-core: Remove experimental toggle com.twitter.util.BypassScheduler used
for speeding up ConstFuture.map (transformTry). Now, we always run map
operations immediately instead of via the Scheduler, where they may be queued
and potentially reordered.
PHAB_ID=D338487
- util-core: Fixed the behavior in c.t.io.Reader where reading from Reader#empty fails to return
a ReaderDiscardedException after it's discarded.
PHAB_ID=D325465
- util-core: Use Local at callback creation for Future's interrupt handler rather than
raiser's locals so that it is consistent with other callbacks. This functionality is
currently disabled and can be enabled by a toggle (com.twitter.util.UseLocalInInterruptible)
by setting it to 1.0 if you would like to try it out.
PHAB_ID=D324315
No Changes
- util-app: Track the registration of duplicated Flag names. Currently, we print a warning to
stderr but do not track the duplicated Flag names. Tracking them allows us to inspect and
warn over the entire set.
PHAB_ID=D314410
- util-app: Improve usage of Flag.let by providing a Flag.letParse method
PHAB_ID=D288549
- util-core: Discard parent reader from Reader.flatten when child reader encounters an exception.
PHAB_ID=D281830 - util-core: Added c.t.conversions.StringOps#toSnakeCase,toCamelCase,toPascalCase implementations.

and Reader.fromSeq to create a new Reader from a Seq.
PHAB_ID=D255424 - util-core: Added Duration.fromMinutes to return a Duration from a given number of minutes.
PHAB_ID=D259795 - 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.
PHAB_ID=D229728 - util-core: Optimized ConstFuture.proxyTo which brings the performance of
flatMap and transform of a ConstFuture in line with map.
PHAB_ID=D271358 - 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.
PHAB_ID=D271962 - util-security: Pkcs8KeyManagerFactory now supports a certificates file which contains multiple
certificates that are part of the same certificate chain.
PHAB_ID=D263190
- util-core: Fixed the behavior in c.t.io.Reader where Reader#flatMap fails to propagate
parent reader's onClose.
PHAB_ID=D269413
- 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.
PHAB_ID=D229728
- 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.
PHAB_ID=D269404 - util-core: Deprecated conversions in c.t.conversions have new implementations
that follow a naming scheme of SomethingOps.
PHAB_ID=D272206- 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.
PHAB_ID=D270548 - util-core: Rename BlacklistStatsReceiver to DenylistStatsReceiver.
PHAB_ID=D270526 - util-core: Buf.Composite is now private. Program against more generic, Buf interface instead.

renamed to have unique names. This allows them to be used together with wildcard imports.
See Github issue (twitter#239).
PHAB_ID=D252462 - util-core: Both c.t.io.Writer.FailingWriter and c.t.io.Writer.fail were removed. Build your
own instance should you need to.
PHAB_ID=D256615
- 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.
PHAB_ID=D236311 - 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.
PHAB_ID=D249403- percent is now PercentOps
- storage is now StorageUnitOps
- string is now StringOps
- thread is now ThreadOps
- time is now DurationOps

PHAB_ID=D236311 - util-core: Removed c.t.util.U64 bits. Use c.t.converters.u64._ instead.
PHAB_ID=D244723
- 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.
PHAB_ID=D229559 - util-core: Rename c.t.io.Reader.ReaderDiscarded to c.t.io.ReaderDiscardedException.
PHAB_ID=D231969
- util-core: Made Stopwatch.timeNanos monotone.
PHAB_ID=D236629

chunkSize, the upper bound of the number of bytes that a given reader emits at each read.
PHAB_ID=D203154
- util-core: c.t.u.Duration.inTimeUnit can now return
j.u.c.TimeUnit.MINUTES.
PHAB_ID=D225115
- util-core: c.t.io.Writer now extends c.t.util.Closable. c.t.io.Writer.ClosableWriter
is no longer exist.
PHAB_ID=D218453 - util-core: Add onClose into c.t.io.Writer, it exposes a Future that is satisfied when
the stream is closed.
PHAB_ID=D226319
- util-slf4j-api: Moved slf4j-simple dependency to be a 'test' dependency, instead of a
compile dependency, which was inaccurate.
PHAB_ID=D220718
- util-core: Added a contramap function into c.t.io.Writer, Writer is now a contravariant
functor. Added the AbstractWriter for Java compatibility

- util-tunable: Introducing Tunable.asVar that allows observing changes to tunables.
PHAB_ID=D211622
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.
PHAB_ID=D195638util-core: InMemoryStatsReceiver now eagerly creates the mappings for Counters and Stats instead of waiting for the first call to Counter.incr and Stat.add.
PHAB_ID=D205760util-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.
PHAB_ID=D199536util-slf4j-api: Ensure that marker information is used when determining if log level is enabled for methods which support markers.
PHAB_ID=D202387util-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.
PHAB_ID=D204330
- 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.

no longer recommend that people do this.
PHAB_ID=D174250
- util-app: Fix issue where in some environments, URLClassLoader#getURLs can
return null, failing LoadService from initializing properly
(see: google/guava#2239). The URLClassLoader javadoc
is not clear if a null can be returned when calling URLClassLoader#getURLs and for
at least one application server, the default returned is null, thus we should be more
resilient against this possibility. Fixes Finagle #695.
PHAB_ID=D181152
- util-reflect: This library has been deprecated since it is legacy code and shouldn't
be used for new services. We no longer think this facility is the right way to do it
and encourage you to provide your own forwarders.
PHAB_ID=D174250
- util-app: added #suppressGracefulShutdownErrors method to optionally suppress exceptions
during graceful shutdown from bubbling up.

PHAB_ID=D152000
util-app: Add visibility for NonFatal exceptions during exiting of c.t.app.App. Added visibility into any NonFatal exceptions which occur during the closing of resources during App#close.
PHAB_ID=D146029util-core: Ensure the Awaitable.CloseAwaitably0.closeAwaitably Future returns. Because the closed AtomicBoolean is flipped, we want to make sure that executing the passed in f function satisfies the onClose Promise even the cases of thrown exceptions.
PHAB_ID=D146565util-stats: Alphabetically sort stats printed to the given PrintStream in the c.t.finagle.stats.InMemoryStatsReceiver#print(PrintStream) function.
To include stats headers which provide better visual separation for the different types of stats being printedm, set includeHeaders to true. E.g.,
` InMemoryStatsReceiver#print(PrintStream, includeHeaders = true) `PHAB_ID=D144091
- util-app: Ensure that any flag parsing error reason is written to System.err
before attempting to print flag usage. In the event that collecting flags for
the printing the usage message fails, users will still receive a useful message
as to why flag parsing failed.
PHAB_ID=D137629 - util-core: Promises/Futures now use LIFO execution order for their callbacks
(was depth-based algorithm before).
PHAB_ID=D135407 - util-core: Wrap the function passed to Closable.make in a try/catch and return

PHAB_ID=D137893- new RichU64String("123").toU64Long -> Long.parseUnsignedInt
- new RichU64Long(123L).toU64HexString -> Long.toHexString (no leading zeros)
- util-core: Added implicit conversion for percentage specified as "x.percent"
to a fractional Double in c.t.conversions.percent.

c.t.u.tunable.JsonTunableMapper, and c.t.u.tunable.ServiceLoadedTunableMap are now public.
This allows users to create and use Tunables, a mechanism for accessing dynamically
configured values. See https://twitter.github.io/finagle/guide/Configuration.html#tunables
for details on how these can be used in Finagle.
PHAB_ID=D80751.
- util-core: Fix some consistency issues with c.t.util.ByteReaderImpl. Advance its
cursor by the number of bytes consumed via readBytes(Int), not the number specified

of bytes specified exceeds the remaining buffer length instead of silently making due
with the rest of the buffer's contents.
PHAB_ID=D78301
- util-core: c.t.util.Closable.sequence now continues processing
the Closables should any of their closes result in a failed Future

RB_ID=910152 - util-core: Add Java-friendly API to Scala.java for converting from
a Java 8 Optional to a Scala Option.
RB_ID=906512 - util-core: Introduced a positional Buf API, Buf.Indexed, and retrofitted
all existing implementations in util and finagle to adopt it. It is now used
throughout for a reductions in allocation and latency. In two services at
Twitter we saw a 1-2% reduction in allocations. We plan to open the API to
the public and make it a part of Buf once we are confident in the APIs.
RB_ID=904559RB_ID=905253RB_ID=906201 - util-slf4j-api: Introduce slf4j-api support into util. This includes a
small scala wrapper over the org.slf4j.Logger and a scala-friendly
Logging trait. Changes also include the util-slf4j-jul-bridge module which
is a library that provides a utility to "smartly" install the
Slf4jBridgeHandler.
RB_ID=900815
- util-core: Improved performance and allocation rates of some "random access"
Buf operations.
RB_ID=905253 - util-core: Standardized argument checking in implementations of
c.t.io.Buf.write and c.t.io.Buf.slice.
RB_ID=899935
- util-core: Deprecated c.t.io.ConcatBuf which is replaced by
c.t.io.Buf.apply(Iterable[Buf]).
RB_ID=899623
- util-core: Fix issue with c.t.concurrent.AsyncStream.mapConcurrent which
will cause the stream head to be held for life of operation.
RB_ID=896168
- util-core: Deprecated charset constants in c.t.io.Charsets have been
removed. Use java.nio.charset.StandardCharsets instead.
RB_ID=893542 - util-core: com.twitter.util.NonFatal is deprecated, use
scala.util.control.NonFatal instead.
RB_ID=892475 - util-core: FactoryPool/SimplePool now inherits scala.collection.mutable.Queue[A]
not deprecated scala.collection.mutable.QueueProxy[A]
RB_ID=896485 - util-core: Buf has been promoted from a trait to an abstract class to facilitate
memoization of the Buf hash code. This also removes the need for the Java friendly
abstract class: AbstractBuf.
RB_ID=897476
No Changes
- util-app: Java developers can now declare instances of GlobalFlag
from Java. See c.t.app.JavaGlobalFlag for details.
RB_ID=874073 - util-thrift: We now depend on a fork of libthrift hosted in the Central Repository.
The new package lives in the 'com.twitter' organization. This removes the necessity of
depending on maven.twttr.com. This also means that eviction will not be automatic and
using a newer libthrift library requires manual eviction if artifacts are being pulled
in transitively.
RB_ID=885879 - util-logging: Allow users to override c.t.util.logging.Logger installation,
making it easier to work with SLF4J bridges.
RB_ID=870684 - util: No longer need to add an additional resolver that points to maven.twttr.com.
RB_ID=878967
- util-core: c.t.io.InputStreamReader and Readers created by
c.t.io.Reader.fromFile and fromStream now close the underlying
InputStream on reading of EOF and on calls to Reader.discard.
RB_ID=873319
- util-core: c.t.app.GlobalFlag is now abstract to reflect how the class
is intended to be used.
RB_ID=875409
- util-app: Introduce c.t.app.Flag.letClear allowing flags to be unset.
RB_ID=868177
- util-core: c.t.util.FuturePool now optionally exposes metrics on
their internal state such as active tasks, and completed tasks.
RB_ID=850652 - util-core: Add a system property
com.twitter.concurrent.schedulerSampleBlockingFraction that can be
set to a value between 0.0 and 1.0 (inclusive). When the Scheduler
runs blocking code, it will log the stacktrace for that fraction of
the calls.
RB_ID=861892 - util-core: Add Java-friendly API for StorageUnit. See StorageUnit.fromX
and StorageUnit.{times, plus, minus, divide} methods.
RB_ID=864546
- util-eval: The compiler reporter is now reset between code check invocations.
This means that when there is a failure that it is no longer required to reset
the entire state to recover and that already compiled and loaded classes can still
be used.
RB_ID=859878
- util-codec: StringEncoder no longer depends on apache commons-codec, and
decode will now throw an exception when it fails to decode a byte, instead
of failing silently.
RB_ID=833478 - util-collection: LruMap is now backed by jdk LinkedHashMap instead of apache
collections LRUMap.
RB_ID=833515 - util-core: com.twitter.util.NonFatal is now implemented by Scala's
scala.util.control.NonFatal. This changes behavior such that
java.lang.StackOverflowError is considered fatal and
java.lang.NoSuchMethodException is considered non-fatal.
RB_ID=835671
- util-app: com.twitter.finagle.util.LoadService has been moved to
c.t.app.LoadService and can now be used without needing a finagle-core
dependency.
RB_ID=829897 - util-cache: Adds support for Caffeine-style caches.
RB_ID=833848 - util-core: Add c.t.concurrent.Scheduler.blockingTimeNanos which tracks time spent doing
blocking operations.
RB_ID=828289 - util-core: Reduced allocations by 40% and latency by 18% of satisfying Promises.
RB_ID=832816 - util-core: c.t.util.NoStacktrace is removed. Use scala.util.control.NoStackTrace instead.
RB_ID=833188 - util-core: Add Future.joinWith that also accepts a function (A, B) => C for mapping
a joined result.
RB_ID=838169 - util-core: Add Future.by(Time), complementary to the existing Future.within(Duration)
RB_ID=838169 - util-core: Add c.t.util.ProxyTimer which allows for creating proxy based
Timers outside of the com.twitter.util package.
RB_ID=846194 - util-core: Add AsyncStream.merge merge potentially inifite streams
RB_ID=846681 - util-security: Added new project.
RB_ID=843070
- Builds are now only for Java 8 and Scala 2.11. See the
blog post
for details.
RB_ID=828898 - util-core: c.t.u.Bijection is removed. use c.t.bijection.Bijection
(https://github.com/twitter/bijection) instead.
RB_ID=834383 - util-core: Deprecated method Future.get() has been removed because it made it
too easy to hide blocking code. Replaced usage with the more explicit
com.twitter.util.Await.result(Future).
RB_ID=833579 - util-core: Deprecated method Future.get(Duration): Try has been removed because it
made it too easy to hide blocking code. Replaced usage with the more explicit
com.twitter.util.Await.result(Future.liftToTry).
RB_ID=836066 - util-core: Deprecated methods Future.isReturn and Future.isThrow have been
removed because they made it too easy to hide blocking code. Replaced usage with
the more explicit Await.result(Future.liftToTry).isReturn and
Await.result(Future.liftToTry).isThrow.
RB_ID=837329 - util-lint: Added methods com.twitter.util.lint.Rules.removeById(String) and
com.twitter.util.lint.RulesImpl.removeById(String) so that it is now possible
to remove a com.twitter.util.lint.Rule from the com.twitter.util.lint.GlobalRules
set.
RB_ID=840753
- util-core: AsyncMeter had a bug where if the burst size was smaller than
the number of disbursed tokens, it would discard all of the tokens over
the disbursal limit. Changed to instead process tokens in the wait queue
with leftover tokens. This improves behavior where the actual period is
smaller than can actually be simulated with the given timer.
RB_ID=836742 - util-core: Once didn't actually provide the guarantee it tried to, because
of an issue with the scala compiler,
https://issues.scala-lang.org/browse/SI-9814. It should now actually be
synchronized.
RB_ID=842245 - util-zk: Fixed race when an existing permit is released between the time
the list was gotten and the data was checked.
RB_ID=835856 - util-core: Memoize apply now throws IllegalStateException if a thread re-enters with identical input parameters instead of deadlocking.
- util-core: Add Throwables.unchecked to help Java users deal with checked
exceptions.
RB_ID=811441 - util-stats: Can now get from a com.twitter.finagle.stats.StatsReceiver` to all "leaf"
StatsReceivers that don't delegate to another StatsReceiver with
com.twitter.finagle.stats.DelegatingStatsReceiver.all.
RB_ID=819519
- util-core: Removed deprecated methods from Buf.scala
RB_ID=809948- Removed c.t.io.Buf.ByteArray.apply, replace usage with Buf.ByteArray.Owned.apply. - Removed c.t.io.Buf.ByteArray.unapply, replace usage with Buf.ByteArray.Owned.unapply. - Removed c.t.io.Buf.ByteBuffer.apply, replace usage with Buf.ByteBuffer.Owned.apply. - Removed c.t.io.Buf.toByteBuffer, replace usage with Buf.ByteBuffer.Owned.extract. - util-core: Removed deprecated Future.apply methods
RB_ID=811617 - util-stats: Removed com.twitter.finagle.stats.BroadcastStatsReceiver marker trait in favor of
com.twiter.finagle.stats.DelegatingStatsReceiver marker trait, which lets us specify that we
only delegate to a single com.twitter.finagle.stats.StatsReceiver.
RB_ID=819519 - util-zk-common: Removed com.twitter.zk.ServerSet. Use implementations of ServerSets in the
finagle-serversets project.
RB_ID=821355

It can be used for smoothing out bursty traffic, or for slowing down access to a
resource.
RB_ID=756333 - util-core: Introduce a TokenBucket for helping to control the relative rates of two processes,
or for smoothing out the rate of a single process.
RB_ID=756333
- util-core: Timer now has final implementations for schedule which delegate
to new protected scheduleOnce and schedulePeriodically methods. This is
done to ensure that Locals are captured when the task is scheduled and
then used when the task is run. Existing Timer implementations should rename
their existing schedule methods to work with the new interface.
RB_ID=755387 - util-core: Remove deprecated FuturePool.defaultPool, callers should
use FuturePool.unboundedPool instead.
RB_ID=757499 - util-stats: Remove deprecated methods on com.twitter.finagle.stats.StatsReceiver.
RB_ID=757414 - util-core: AsyncStream graduates out of com.twitter.concurrent.exp into
com.twitter.concurrent. Backwards compatibility aliases remain for Scala
users, but Java users will need to update their imports.
RB_ID=758061 - util-codec: Add a new encoder com.twitter.util.Base64UrlSafeStringEncoder
which extends from com.twitter.util.Base64StringEncoder. Both the url-safe
and non-url-safe encoders can decode all strings generated by either.
RB_ID=765189 - util-core: Remove unnecessary invalidate method from util-cache's
com.twitter.cache.guava.LoadingFutureCache, and change the remove semantic
to match the com.twitter.cache.FutureCache contract.
RB_ID=766988 - util-core: Remove protected Timer.monitor (overrides a monitor to use by a
timer implementation) because any possible implementation rather than Monitor.get
promotes memory leaks when timer is used to schedule recursive tasks (tasks that
reschedules themselves).
RB_ID=771736
- util-core: Introduce an optional max capacity to AsyncQueue.
Modified AsyncQueue.offer to return a boolean indicating whether or not the
item was accepted. Added AsyncQueue.drain(): Try[Queue].
RB_ID=745567
- util-core: Remove deprecated methods from com.twitter.util.Time and
com.twitter.util.Duration.
RB_ID=751771 - util-core: Provide methods on Stopwatch so that users can take advantage of
Time manipulation tools in latency-sensitive code when measuring elapsed
time.
RB_ID=75268
- util-core: The Scheduler clock stats were decommissioned as they only make sense
relative to wallTime and the tracking error we have experienced wallTime and
*Time make it impossible to use them reliably. It is not worth the performance
and code complexity to support them.
RB_ID=750239 - util-core: JavaTimer and ScheduledThreadPoolTimer now capture the Local
state when scheduled and is used along with that Monitor when the TimerTask
is run.
RB_ID=755387 - util-logging: QueueingHandler does not create a separate thread per instance.
RB_ID=745567
util-core: Remove deprecated methods from com.twitter.util.Var.
To migrate observe and foreach, given aVar.observe { t => somethingWith(t) } you would write aVar.changes.register(Witness({ t => somethingWith(t) })).
To migrate observeUntil, given aVar.observeUntil(_ == something), you would write aVar.changes.filter(_ == something).toFuture().
To migrate observeTo, given aVar.observeTo(anAtomicReference), you would write aVar.changes.register(Witness(anAtomicReference)).
RB_ID=744282
- util-core: TimeFormat optionally takes a TimeZone in the constructor. If not provided, it uses UTC.
- util-core: Activity, BoundedStack, RingBuffer and Var migrated
off of deprecated ClassManifest to ClassTag.

- util-core: TimeFormat now throws IllegalArgumentException if the pattern
- uses the week year ('Y') without the week number ('w')
- util-core: Spool.++ used to force its argument, but now it is evaluated
- only if this Spool is empty. To revert to existing behavior, simply force the argument before passing it to ++.
- util-core: Reader.writable() returns a new type, Reader.Writable, which
- combines Reader, Writer and Closable.
- util-core: Reader.concat and Reader.copyMany now take an AsyncStream
- argument instead of Spool.

- them.
- util-core: Future.onFailure now only applies a PartialFunction if
- PartialFunction.isDefinedAt returns true.

- StatsReceivers to. They retain the com.twitter.finagle namespace to ease the transition.
Deprecation:
- util-stats: Deprecate com.twitter.finagle.stats.StatsReceiver#time{,TimeFuture}.

- util-core: Add compilation tests to track Java compatibility of new API
- util-core: Removed Sieve example.
- util-core: Introduce new constructors and extractors for Buf types to
- support more efficient, correct uses. Buf types now come with Copied and Direct management interfaces -- Direct tries to provide direct access to the Buf's backing byte array, while Copied ensures that the caller cannot accidentally mutate a Buf's data. Additionally, helpers to support Buf-type coersion have been added.
