  • v3.0.0

    This is a major version as there are some minor API breaking changes which may effect users. Please apply with care and provide feedback. The breaking changes:

    ✂ Removed MpscLinkedQueue7 and MpscLinkedQueue8 and consolidate into parent. This removes the need for the builder method on MpscLinkedQueue. 📦 Deprecated QueueFactory and spec package classes. These are not used by any users AFAICT and are only used for testing internally. ✂ Removed some internal classes and reduced visibility of internal utilities where practical. The @InternalAPI tagging annotation is also used more extensively to discourage dependency. We also have some great new queues for y'all to try:

    • #226: XADD unbounded mpsc/mpmc queue: highly scalable linked array queues (from @franz1981)
    • 🆕 New blocking consumer MPSC (with contributions and bug fixes from @njhill)

    🐛 Bug fixes:

    • #209: On Arm7, non-volatile long can have unaligned address leading to error
    • #216: Size of SpscGrowableArrayQueue can exceeds max capacity (from @franz1981 PR #218)
    • #241: Protect the producer index in case of OutOfMemoryError (from @franz1981)
    • #244: Long NBHM AssertionError when replacing missing key (thanks @fvlad for reporting and @cliffclick for assistance and review)
    • 🛠 Fix argument checks on fill/drain methods
    • 🛠 Fix LGTM warning, potential int overflow bug b467d29, 15d944c, 6367951

    👌 Improvements:

    • Don't mark generated linked atomic queues as final (from @kay 9db418c)
    • #211: Implement batching methods on MpmcArrayQueue (from @franz1981)
    • #228: Iterator for MpscArrayQueue and MpscUnboundedArrayQueue (PR #229 from @srdo)
    • 👍 Iterator support also available for the *ArrayQueue classes
    • #208: MpscLinkedAtomicQueue can be made not final
    • 👻 #237: Add scale to exception message to help debug netty/netty#8916 (from @johnou)

    ✅ Many other improvements to testing, javadoc, formatting were made with some contributions from @Hearen @JanStureNielsen @nastra thanks!

  • v2.0.1

    January 03, 2017

    🛠 Fixing up a couple of issues:

    • 0️⃣ #143 - toString() didn't work for many of the queues because the default implemetation relied on iterators.
    • 🛠 #151 fixed by @cliffclick and helped by @vyazelenko - bringing in some fixes and improvements to NHBM
    • Minor javadoc touchups
  • v2.0

    October 28, 2016
    • 🚀 PR #94 : The NonBlockingHashMap by @cliffclick is now released as part of JCTools core. Also thanks to @pcholakov for help is converting and sanity testing some of the benchmark code (PR #108).
    • PR #129 : MPSC linked array queues code is tidied up and split into 3 implementations. The old Chunked is here, but constructor has changed. Growable is split from chunked and Unbounded is added.
    • 🐛 Bug #135 : Bug fix for the growable MPSC case.
    • PR #127 : Releasing JCTools as an OSGi bundle, thanks @CodingFabian !
  • v1.2.1

    June 24, 2016
    • PERF: Fix GC nepotism issue in SpscUnboundedArrayQueue (Issue #95, PR #96, courtesy of @akarnokd)
    • PERF: Unified base implementation to SpscUnbounded/Growable (Issue #103, PR #107, courtesy of @pcholakov)
    • 🐛 BUG: IllegalStateException during MpscChunkedArrayQueue.offer(....) (Issue #115)
    • 🐛 BUG: new MpscChunkedArrayQueue(1024, Integer.MAX_VALUE, ...) throws confusing exception (Issue #116)
    • 🐛 BUG: SpscGrowable/SpscUnbounded/SpscAtomic/SpscUnboundedAtomic !isEmpty() but poll() == null (Issue #119)
    • 🐛 BUG: MpscArrayQueue.offerIfBelowTheshold is broken: offering is still possible when queue is full (Issue #120)
  • v1.2

    March 15, 2016
    • ➕ Added MpscChunkedArrayQueue an MPSC bounded queue aiming to replace current usage of MpscLinkedQueue in usecases where low footprint AND low GC churn are desirable. This is acheived through usage of smaller buffers which are then linked to either bigger buffers or same sized buffers as queue size demands.
    • 🛠 Fixed a GC nepotism issue in linked queues. This is not a bug but an observable generational GC side effect causing false promotion of linked nodes because of a reference from a promoted dead node. See discussion here: akka/akka#19216
    • 🛠 Fixed an inconsistently handled exception on offering null elements. This was a bug in MpmcArrayQueue.
    • ♻️ Formatting and refactoring
