  • v21.4.0 Changes

    ⚙ Runtime Behavior Changes

    
* util-reflect: Memoize `c.t.util.reflect.Types#isCaseClass` computation. ``PHAB_ID=D657748``

💥 Breaking API Changes
    • 📇 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 Expressions 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

    🆕 New Features

    
* 📇 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.

  • v21.3.0 Changes

    ⚙ Runtime Behavior Changes

    
* ⏪ util: Revert to scala version 2.12.12 due to https://github.com/scoverage/sbt-scoverage/issues/319
  ``PHAB_ID=D635917``

* util: Bump scala version to 2.12.13 ``PHAB_ID=D632567``

💥 Breaking API Changes

    • 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

    🆕 New Features

    
* 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`.

  • v21.2.0 Changes

    No Changes

  • v21.1.0 Changes

    No Changes

  • v20.12.0 Changes

    💥 Breaking API 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``

🆕 New Features

    • 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

    ⚙ Runtime Behavior Changes

    
* 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``

  • v20.10.0 Changes

    October 27, 2020

    🐛 Bug Fixes

    • 📇 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. 7665b9eb
    • 🗄 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.
      26e7874b

  • v20.9.0 Changes

    September 22, 2020

    🆕 New Features

    
* 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``

💥 Breaking API Changes
    • 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

    ⚙ Runtime Behavior Changes

    
* util: Bump version of Jackson to 2.11.2. ``PHAB_ID=D538440``

    🆕 New Features

    • ✅ util-stats: Store MetricSchemas in InMemoryStatsReceiver to enable further testing. c305712e

    • util-core: Added two new methods to c.t.u.Duration and c.t.u.Time: .fromHours and .fromDays. 955f2ce9

    ⚙ Runtime Behavior Changes

    • 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
