quasar - 0.7.4

Published by circlespainter almost 9 years ago

New features

Suspendable CountDownLatch and CyclicBarrier

Improvements

Several dependencies upgraded

quasar - 0.7.3

Published by circlespainter about 9 years ago

Breaking changes

Kotlin's fiber function has been moved to the co.paralleluniverse.kotlin package, has several convenient overloads and by default will also start the fiber.

New features

co.paralleluniverse.kotlin also includes a convenient select syntax to perform channel selection:

val ch1 = Channels.newChannel<Int>(1)
val ch2 = Channels.newChannel<Int>(1)

assertTrue (
    fiber {
        select(Receive(ch1), Send(ch2, 2)) {
            it
        }
    }.get() is Send
)

ch1.send(1)

assertTrue (
    fiber {
        select(Receive(ch1), Send(ch2, 2)) {
            when (it) {
                is Receive -> it.msg
                is Send -> 0
                else -> -1
            }
        }
    }.get() == 1
)

The new FiberForkJoinScheduler.onIdle() hook notifies when the fiber scheduler becomes idle.

Improvements

Several dependencies upgraded

Closed issues:

quasar - 0.7.2

Published by pron over 9 years ago

New features:

A fully TCK-compliant Reactive Streams implementation based on Quasar Channels in the quasar-reactive-streams module

Improvements:

Instrumentation optimisation has been introduced: methods that don't need instrumentation will be left untouched and this improves performance
Instrumentation verification is more precise, it checks call sites (see #86) and it prints extended stack trace information on HotSpot JRE 8; in addition it works even without verification enabled (and without performance penalty) when an uncaught exception is thrown in a fiber
Improved JDK8-optimised build, no duplicate classes anymore (see #91)
Minor channels improvements and fixes
Kotlin upgraded to 0.12.613(post-M12) and several other dependencies upgrade
The @Suspendable annotation is now supported on individual interface methods rather than just on the whole interface

Closed issues:

#86
#91
#93
#94
#95
#96
A minor issue in scanSuspendables has been addressed, it sometimes included unnecessary (but harmless) lines in suspendable-supers

Notes:

The Gradle wrapper has been removed to simplify the codebase and its maintenance. If you're building Quasar locally just install the latest Gradle distribution before doing so and use plain gradle

quasar - 0.7.0

Published by circlespainter over 9 years ago

Breaking changes:

FiberSocketChannel and FiberServerSocketChannel are created passing a ChannelGroup rather than an AsynchronousChannelGroup; this makes them independent from the async channels API
quasar-core is now a provided dependency for quasar-actors and quasar-galaxy rather than a compile one

New features:

Initial Kotlin support (quasar-kotlin module)
StrandFactory API
Additional transforming channels for take, reduce, split operations
ReceivePortGroup now supports additional mix-style operations
Pipeline channel transfer utility
Additional FiberSocketChannel.connect() with timeout
New Java8 lambdas API for ports
New FiniteStateMachine behavior
getChildren in supervisor actors

Improvements:

Faster fiber stack layout and improved fiber stack management performance
Improved buffered channels performance
ProxyServer performance improvement
Migration from glib to byte-buddy
Dependencies upgrade

Closed issues:

#73
#74
#76
#78
#79
#81
#82
#87
#90
Fix possible SupervisorActor NPE
Duplicate files in quasar-core-jdk8.jar
Possible instrumentation problem with conditionally initialized arrays

quasar - 0.6.2

Published by pron almost 10 years ago

This is a bug-fix release. Fixed bugs include:

In addition, quasar-core now embeds shadowed ASM artifacts rather than externally depending on ASM.

quasar - 0.6.1

Published by pron about 10 years ago

Closed Issues

#54
#55
#61
#62
#63
NPE in QuasarURLClassLoader/QuasarURLClassLoaderHelper

quasar - 0.6.0

Published by pron about 10 years ago

New Features:

Automatic suspendable method detection
Fiber serialization
Actor migration
Dataflow variables

Changes and Improvements

Fiber.join and Fiber.get are now suspendable rather than thread-blocking. This should improve join performance.
co.paralleluniverse.strands.channels.DelayVal is now co.paralleluniverse.strands.dataflow.Val
FiberAsync has been simplified
Much improved fiber-blocking NIO performance
