util-7.0.0

New Features:

  • util-core: Added c.t.util.SlowProbeProxyTimer for monitoring the duration
    of execution for timer tasks. PHAB_ID=D70279

  • util-core: Introduced RootMonitor#set to set custom Monitor to RootMonitor.
    PHAB_ID=D70876

  • util-jvm: JvmStats has been moved here from TwitterServer allowing broader
    access to many metrics including GC, allocations, memory, and more.
    PHAB_ID=D80883

  • util-stats: Introducing Verbosity Levels for StatsReceivers (see docs on StatsReceiver
    for more info). PHAB_ID=D70112

  • util-tunable: c.t.u.tunable.Tunable, c.t.u.tunable.TunableMap,
    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.

Bug Fixes:

  • 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
    as a method argument. readString will now throw an UnderflowException if the number
    of bytes specified exceeds the remaining buffer length instead of silently making due
    with the rest of the buffer's contents. PHAB_ID=D78301

Runtime Behavior Changes:

  • util-core: c.t.util.Closable.sequence now continues processing
    the Closables should any of their closes result in a failed Future
    and will return the first failure. Synchronous exceptions are now
    handled by lifting them into failed Futures. PHAB_ID=D62418

  • util-events: com.twitter.util.events.sinkEnabled now defaults to false
    in preparation for removal in an upcoming release. PHAB_ID=D64437

API Changes:

  • util-core: ByteWriter has been transformed into a true trait which can now
    be implemented outside of the com.twitter.io package. PHAB_ID=D59996

  • util-core: The method ByteWriter.owned() has been moved to a sub trait,
    BufByteWriter, to separate the notion of the target buffer representation from the
    writer methods in order to make it easier to target different buffer representations.
    PHAB_ID=D61215

  • util-stats: PHAB_ID=D59762

  • ProxyStatsReceiver.self is now protected (was public before).
  • StatsReceiver.repr is now def (was val before).

  • util-stats: Counter#add now takes a Long instead of an Integer as an argument.
    PHAB_ID=D69064

  • util-stats: StatsReceiver#counter, StatsReceiver#stat, and StatsReceiver.addGauge
    now may optionally take c.t.f.stats.Verbosity as a first argument. PHAB_ID=D70112

Deprecations:

  • util-events: This module is deprecated and will be removed in an upcoming
    release. PHAB_ID=D64437

  • util-stats: PHAB_ID=D62611

    • StatsReceiver.counter0 is deprecated in favour of vararg StatsReceiver.counter
    • StatsReceiver.stat0 is deprecated in favour of vararg StatsReceiver.stat
