Exception propagation logic from cancelled coroutines is adjusted

* When cancelled coroutine crashes due to some other exception, this
other exception becomes the cancellation reason of the coroutine, while
the original cancellation reason is suppressed.
* UnexpectedCoroutineException is no longer used to report those cases
as is removed.
* This fixes a race between crash of CPU-consuming coroutine and
cancellation which resulted in an unhandled exception and lead to
crashes on Android.

Library support for Kotlin coroutines. This is a companion version for Kotlin 1.1.4 release (this is the minimal required Kotlin runtime version).

Modules

  • core -- core primitives to work with coroutines:
    • launch, async, produce, actor, etc coroutine builders;
    • Job and Deferred light-weight future with cancellation support;
    • CommonPool and other coroutine contexts;
    • Channel and Mutex communication and synchronization primitives;
    • delay, yield, etc top-level suspending functions;
    • select expression support and more.
  • reactive -- modules that provide builders and iteration support for various reactive streams libraries:
    • Reactive Streams, RxJava 1.x and 2.x and Project Reactor.
  • ui -- modules that provide coroutine dispatchers for various single-threaded UI libraries:
    • Android, JavaFx, and Swing.
  • integration -- modules that provide integration with various asynchronous callback- and future-based libraries.
    • JDK8 CompletableFuture, Guava ListenableFuture, and synchronous networking/IO.

Documentation

Using in your projects

Note that these libraries are experimental and are subject to change.

The libraries are published to kotlinx bintray repository, linked to JCenter and pushed to Maven Central.

Maven

Add dependencies (you can also add other modules that you need):

<dependency>
    <groupId>org.jetbrains.kotlinx</groupId>
    <artifactId>kotlinx-coroutines-core</artifactId>
    <version>0.19.1</version>
</dependency>

And make sure that you use the latest Kotlin version:

<properties>
    <kotlin.version>1.1.51</kotlin.version>
</properties>

Gradle

Add dependencies (you can also add other modules that you need):

compile 'org.jetbrains.kotlinx:kotlinx-coroutines-core:0.19.1'

And make sure that you use the latest Kotlin version:

buildscript {
    ext.kotlin_version = '1.1.51'
}

ProGuard

In obfuscated code, fields with different types can have the same names, and AtomicReferenceFieldUpdater may be unable to find the correct ones. To avoid field overloading by type during obfuscation, add this to your config:

-keepclassmembernames class kotlinx.** {
    volatile <fields>;
}
