…1158) * Fix exception types for channels to ensure transparency & reporting * ReceiveChannel.cancel always closes channel with CancellationException, so sending or receiving from a cancelled channel produces the corresponding CancellationException. * Cancelling produce builder has similar effect, but an more specific instance of JobCancellationException is created. * This ensure that produce/consumeEach pair is transparent with respect to cancellation and can be used to build "identity" transformation of the flow (the corresponding test is added). * ClosedSendChannelException is now a subclass of IllegalStateException, so that trying to send to a channel that was closed normally is reported as program error and is not eaten (test is added). Fixes #957 Fixes #1128 * Exceptions for channels cleanup * Documentation improved * Better exception message * Simplified flowOn implementation * Avoid exception instantiation on happy path in zip
…outines.test package to avoid FQN clash Fixes #1159
* Updated to 0.12.7 version of atmoicfu with fixes. * Added test that that is no references to atomicfu in any of the resulting class files. Fixes #1155
* Fixed typos * Added reference to kotlinx-coroutines-test for testing `Main` dispatcher
…id dependency on (frequently) unstable external JavaDoc resources Fixes #648
…able).
* Reasoning about cancellation is simplified in sequential scenarios, if 'cancel' was invoked before withContext return it will throw an exception, thus "isActive == false" cannot be observed in sequential scenarios after cancellation
* withContext now complies its own documentation
Fixes #1177
…lect, transform, map, mapNotNull, filter, filterNot, filterNotNull) as inline
* It is not that useful in an application code (-> is extracted into method), so won't bloat bytecode too much
* It is crucial enough as building block to avoid excess allocations
* Additionally mark inlined builders with labeled return to workaround KT-28938
* RxJava2 by David Karnok
* FlowPlaysScrabbleBase and FlowPlaysScrabbleOpt as flow counterparts
* Lower bounds for Flow scrabble benchmark
* Mark ReceiveChannel.map with @ObsoleteCoroutinesApi Fixes #1162
* combineLatest(Iterable<Flow<T>>) is not added deliberately, use-case is unclear * All specific overloads are marked as inline to reduce binary compatibility pressure Fixes #1193
…otlinx.coroutines
…rimental API Fixes #1080
* Wrap exceptions into CE if parent cancels its child. This is possible because now we can be sure that no one is invoking `cancel(Throwable)`, thus if parent cancels its children, an exception is definitely handled. * Now exception is handled only once First part of fix for #689

Flow performance improvements and reactive benchmarks
#1214) New flow builder: channelFlow (and its alias callbackFlow) and supplementary ProducerScope.await method Rationale: * Can be used in different context without breaking context preservation * Can be used to build concurrent operators such as merge * Can be used to integrate with callbacks * Is less error-prone than flowViaChannel because requires explicit await() call Partially fixes #1210
SafeCollector performance improvements: * Cache result of the context check thus speeding up safe collector on happy path by a factor of three * Separate fast and slow paths in JobSupport to drastically change inlining decisions of the JVM that are crucial for leaf coroutines with flows Strengthen flow context preservation invariant * Add additional check in SafeCollector with an error message pointing to channelFlow * Improve performance of the CoroutineId check in SafeCollector * Change wording in documentation Fixes #1210
* JvmStatic on unbox did not make sense anyway * unbox is useful for other symbols
* Improve MainCoroutineDispatcher.immediate documentation * Remove obsolete readme and package descriptions * Clarify possible replacement of onCompletion parameter in produce * Add paragraph about parent cancellation to async (Mention structured concurrency, but do not explain it there as the term should be easily googlable). Fixes #1219 Fixes #994 Fixes #787
… dispatchers. Use Promise.resolve and process.nextTick as dispatch mechanism for cold starts
The developer still has to disable the FastServiceLoader manually if they're using R8. R8 is then able to optimize away the ServiceLoader and reflection entirely, resulting in direct class instantiation and no extra I/O on calling thread. Fixes #1231
* Introduce buffer operator * Remove buffer size from all the other operators * Fuse all adjacent operators that create channels * Introduce Channel.BUFFERED buffer size marker to request buffered channel with a default (unspecified) size Fixes #1233
In addition, the `SegmentQueue` data structure, which emulates an infinite array with fast removing from the middle, is introduced for storing suspended acquirers in semaphore/mutex/channel algorithms. Fixes #1088
…d provide AbstractFlow instead that enforces context preservation guarantees
