| Summary: Java Concurrency Tools for the JVM | |
This project aims to offer some concurrent data structures currently missing from the JDK: * SPSC/MPSC/SPMC/MPMC Bounded lock free queues * SPSC/MPSC Unbounded lock free queues * Alternative interfaces for queues * Offheap concurrent ring buffer for ITC/IPC purposes * Single Writer Map/Set implementations * Low contention stats counters * Executor
Apache-2.0
* Wed Mar 23 2022 fstrba@suse.com
- Build with java source and target levels 8
* Thu Mar 10 2022 fstrba@suse.com
- Upgrade to 3.3.0
* API Changes:
+ Removed MpscLinkedQueue7 and MpscLinkedQueue8 and consolidated
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.
+ #226: XADD unbounded mpsc/mpmc queue: highly scalable linked
array queues
+ New blocking consumer MPSC
* Bug fixes:
+ #334 NBHMLong iterators do not remove NO_KEY
+ #335 NBHM/Long/Identity iterators only removes keys if values
have not changed. Now follow JDK convention.
+ #336 MpscBlockingConsumerArrayQueue: fix race writing to
blocked field
+ #339 'fill' wakeup call can spin forever (or until a consumer
is blocked again) on MpscBlockingConsumerArrayQueue
+ #319 Relying on test cases provided by #328 we apply the fix
used for #205 to 'NonBlockingHashMapLong' and
'NonBlockingIdentityHashMap' to provide 'getAndSet' like
semantics for put and remove.
+ #330 Fix a 'NonBlockingIdentityHashMap' 'replace' bug. During
this fix some further work was done to bring the code closer
in line to the current state of 'NonBlockingHashMap'
+ Use byte fields for padding (avoid upcoming false sharing
problem in JDK 15+ where field ordering has changed)
+ #289 Add Automatic-Module-Name header to MANIFEST.MF
+ #292 Fix inconsistent isEmpty/poll/peek/offer dynamics for
SpscLinkedQueue
+ Fixed potential for negative queue size for indexed queues and
similar issue with isEmpty
+ #296 Fix peek/relaxedPeek race with poll/offer in MC queues
+ #297 Fix inconsistent size of FF based queues causing
potential size() > capacity()
+ #316 Fix MpscBlockingConsumerArrayQueue::poll(TimeUnit,timeout)
+ #310 Fix MpmcUnboundedXaddArrayQueue::peek/relaxedPeek
can load "future" elements
+ #209: On Arm7, non-volatile long can have unaligned address
leading to error
+ #216: Size of SpscGrowableArrayQueue can exceeds max capacity
+ #241: Protect the producer index in case of OutOfMemoryError
+ #244: Long NBHM AssertionError when replacing missing key
+ Fix argument checks on fill/drain methods
+ Fix LGTM warning, potential int overflow bug
* Enhancements:
+ #326 Xadd queues consumers can help producers
+ #323 Update to latest JCStress (thanks @shipilev )
* Improvements:
+ Don't mark generated linked atomic queues as final
+ #211: Implement batching methods on MpmcArrayQueue
+ #228: Iterator for MpscArrayQueue and MpscUnboundedArrayQueue
+ 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
* New features:
+ #340 MpscBlockingConsumerArrayQueue
+ After long incubation and following a user request (see #321),
we move counters into core
+ Merging some experimental utils and a #264 we add a
'PaddedAtomicLong'
+ #314 MpscBlockingConsumerArrayQueue::offerIfBelowThreshold is
added
- Added patch:
* imports.patch
+ Fix bug in adding of imports that broke build with
javaparser >= 2.15.0
* Tue Oct 01 2019 fstrba@suse.com
- Initial packaging of jctools 2.1.2
