The ReactiveSocketFactory create a ReactiveSocket from an `address` (currently SocketAddress). There are places in the code where the concept of address is not needed and it leads to implicit dependency on it. Solution Add a `double availability()` method to the DuplexConnection interface, most implementation of this method will be straightforward (just returning 0.0 if the underlying resource is unavailable, 1.0 otherwise). Split the concept of ReactiveSocketFactory in two, the Factory and the Connector. The Connector is responsible for creating the ReactiveSocket from the address, and the factory can create a ReactiveSocket without any argument. --- .../reactivesocket/DefaultReactiveSocket.java | 4 + .../io/reactivesocket/DuplexConnection.java | 6 + .../io/reactivesocket/ReactiveSocket.java | 4 +- .../reactivesocket/ReactiveSocketFactory.java | 107 +++--------------- .../io/reactivesocket/internal/Requester.java | 5 +- .../perfutil/PerfTestConnection.java | 7 +- .../io/reactivesocket/TestConnection.java | 5 + 7 files changed, 42 insertions(+), 96 deletions(-) diff --git a/src/main/java/io/reactivesocket/DefaultReactiveSocket.java b/src/main/java/io/reactivesocket/DefaultReactiveSocket.java index 73e90d20f..1ea884980 100644 --- a/src/main/java/io/reactivesocket/DefaultReactiveSocket.java +++ b/src/main/java/io/reactivesocket/DefaultReactiveSocket.java @@ -440,6 +440,10 @@ public void addOutput(Frame f, Completable callback) { connection.addOutput(f, callback);

This was the major driving factor to invest in a _simple_ codec that can reduce allocations and be more suitable for ReactiveSocket design (using thread-local pooled buffers). Although, the codec is intended to be used only for a map type, but it is rather generic to be used for a majority of CBOR data types. If this proves useful, we can extend this for the remaining data types. --- build.gradle | 6 + .../reactivesocket/mimetypes/KVMetadata.java | 13 + .../io/reactivesocket/mimetypes/MimeType.java | 26 +-

+ * + * The benefit of this class is that it does not create additional buffers for the values of the metadata, when + * possible. Instead it holds views into the original buffer and when queried creates a slice of the underlying buffer + * that represents the value. Thus, it is lean in terms of memory usage as compared to other standard libraries that + * allocate memory for all values. + * + *

Allocations

+ * + *

Modifications

+ * + * Any additions to the map (adding one or more key-value pairs) will create a map with all keys and values, where + * values are the buffer slices of the original buffer. From then onwards, the newly created map will be used for all + * further queries.

+ * So, additions to this map will result in more allocations than usual but it still does not allocate fresh memory + * for existing entries. + * + *

Access

+ * + * Bulk queries like {@link #entrySet()}, {@link #values()} and value queries like {@link #containsValue(Object)} will + * switch to a new map as described in case of modifications above. + * + *

Structure

+ * + * In absence of the above cases for allocations, this map uses an index of {@code String} keys to a {@code Long}. The + * first 32 bits of this {@code Long} holds the length of the value and the next 32 bits contain the offset in the + * original buffer. {@link #encodeValueMask(int, long)} encodes this mask and {@link #decodeLengthFromMask(long)}, + * {@link #decodeOffsetFromMask(long)} decodes the mask. + */ +public class CBORMap implements Map { + + protected final DirectBuffer backingBuffer; + protected final int offset; + protected final Map keysVsOffsets; + protected Map storeWhenModified; + + public CBORMap(DirectBuffer backingBuffer, int offset) { + this(backingBuffer, offset, 16, 0.75f); + } + + public CBORMap(DirectBuffer backingBuffer, int offset, int initialCapacity) { + this(backingBuffer, offset, initialCapacity, 0.75f); + } + + public CBORMap(DirectBuffer backingBuffer, int offset, int initialCapacity, float loadFactor) { + this.backingBuffer = backingBuffer; + this.offset = offset; + keysVsOffsets = new HashMap<>(initialCapacity, loadFactor); + } + + protected CBORMap(Map storeWhenModified) { + backingBuffer = new UnsafeBuffer(IndexedUnsafeBuffer.EMPTY_ARRAY); + offset = 0; + this.storeWhenModified = storeWhenModified; + keysVsOffsets = Collections.emptyMap(); + } + + protected CBORMap(DirectBuffer backingBuffer, int offset, Map keysVsOffsets) { + this.backingBuffer = backingBuffer; + this.offset = offset; + this.keysVsOffsets = keysVsOffsets; + storeWhenModified = null; + } + + public Long putValueOffset(String key, int offset, int length) { + return keysVsOffsets.put(key, encodeValueMask(offset, length)); + } + + @Override + public int size() { + return null != storeWhenModified ?

Then, any source associated with the chain continue to emit events. One example of that is the Keep-Alive Observable, which regularly emit keep-alive messages at fixed interval, when the connection is closed, the observable has to be cancelled.

(#88) Problem: `handleXXX` methods in `Responder` were closing over the passed `requestFrame` and using it later in the lifecycle of request processing. `Frame` objects and the underlying buffers are not designed to be retained after the scope of the parent method as these objects are threadlocal and reused. This causes issues when the frame object is referenced later in the request processing (eg: `cleanup()`) Solution: The only reason frame object was retained was to get the stream Id. This change pre-fetches the `streamId` and uses that from within the processing closure.

Also, implementation of DuplexConnection have to return an availability. Solution The Factory to Connector refactoring is pretty straight forward. All implementations of DuplexConnection return an availability which directly map the state of the underlying resource (0.0 if the resource is closed, 1.0 otherwise). This will greatly help the load-balancer to select a valid connection. I removed the blocking method from reactivesocket-java, so I moved some utility blocking code inside the TestUtil class. Clean-up of the Netty implementation, remove unused args, explicitey specify tcp socket configuration. Shortened the toString name to ease log-reading. Bug All DuplexConnection implementations now cancel the subscription when an exception occurs. This fix the problem, where the Keep-Alive Observable kept trying to send a keep-alive on a closed connection. * Refactor the TestUtil helper to return CompletableFuture * rs version * Restore rs dependency to latest.release * Remove mavenLocal in gradle build file * Propagate cancellation in all cases * Use helper method from ReactiveSocket Unsafe ---

(#91) * Split reactivesocket-transport-netty into 2 projects. **Problem** `reactivesocket-transport-netty` isn't an implementation of a transport but two "tcp" and "websocket". Furthermore, Netty is an implementation details rather than a transport. **Solution** Split `reactivesocket-transport-netty` into two transport libraries: - `reactivesocket-transport-tcp` - `reactivesocket-transport-websocket` Introduce a common library `reactivesocket-netty` which only contains two classes `MutableDirectByteBuf` and `NettyDuplexConnection` that are used in both transport libraries. **Note** I didn't touch `ReactiveSocketServerHandler` which is discussed in a PR on the old repo. * Get rid of reactivesocket-netty * Move the tests into the right module * Get

-0700 Subject: [PATCH 117/950] Migrate reactivesocket-load-balancer into reactivesocket-java (#93) **Problem** The multi-repo structure is difficult to use in a context of rapid short iterations. **Solution** Migrate the reactivesocket-load-balancer repo inside reactivesocket-java. The submodules have been renamed like this: - reactivesocket-load-balancer-builder -> reactivesocket-client - reactivesocket-load-balancer-core -> reactivesocket-client - reactivesocket-load-balancer-eureka -> reactivesocket-discovery-eureka - reactivesocket-load-balancer-servo -> reactivesocket-stats-servo I also added a simple module `reactivesocket-examples`, which only contains one file so far. The goal of this module is to demonstrate simple examples. --- reactivesocket-client/build.gradle | 4 + .../io/reactivesocket/client/Builder.java | 263 ++++++++

(#94) ** Problem ** There's a memory leak in `ReactiveSocketServerHandler`, it keep adding entries in the `duplexConnections` map but never remove them. ** Solution ** Instead of having only one `ReactiveSocketServerHandler`, and manage resources manually, we let Netty allocate one instance per Channel. Then no resource management is necessary. ** Modifications ** I refactored all the uage of `ReactiveSocketServerHandler` whithout changing the logic. I also got rid of the method ``` public void channelReadComplete(ChannelHandlerContext ctx) { ctx.flush(); } ``` since we only use `writeAndFlush` in the DuplexConnection (we're sure there's nothing to flush). --- .../transport/tcp/EchoServerHandler.java | 11 +- .../server/ReactiveSocketServerHandler.java | 56 +++--- .../transport/tcp/ClientServerTest.java | 89 +++++----- .../io/reactivesocket/transport/tcp/Ping.java | 12 +- .../io/reactivesocket/transport/tcp/Pong.java | 164 +++++++----------- .../server/ReactiveSocketServerHandler.java | 35 ++-- .../transport/websocket/Ping.java | 12 +- .../transport/websocket/Pong.java | 163 +++++++---------- 8 files changed, 222 insertions(+), 320 deletions(-) diff --git a/reactivesocket-transport-tcp/src/examples/java/io/reactivesocket/transport/tcp/EchoServerHandler.java b/reactivesocket-transport-tcp/src/examples/java/io/reactivesocket/transport/tcp/EchoServerHandler.java index e4263ac08..c7101a80a 100644 --- a/reactivesocket-transport-tcp/src/examples/java/io/reactivesocket/transport/tcp/EchoServerHandler.java +++ b/reactivesocket-transport-tcp/src/examples/java/io/reactivesocket/transport/tcp/EchoServerHandler.java @@ -16,11 +16,10 @@ public class EchoServerHandler extends ByteToMessageDecoder { private static SimpleChannelInboundHandler httpHandler = new HttpServerHandler();

(#105) Problem Since `ReactiveSocket` reads and writes from a transport connection, it is completely expected that at some point the underlying connection may have been severed. In such a case, both the read and write will fail on the connection. This pollutes logs of applications that directly log the error stream (as expected). Modification Since, this is kind of an "expected" exception, there is no point to send this to the error stream. This change adds a filter to the error stream to filter any known exceptions (as of today, it is only `ClosedChannelException`) PS: We currently do not unsubscribe from the input (and stop writing) when `ReactiveSocket` is explicitly closed.

(#115) * Completing subscriber after sending error frame (caused memory leak). #### Problem In some cases, `Responder` was converting an `onError()` to `onNext(Frame.Error)` but was not sending an `onComplete()` after the `onNext()`. This causes the `subscriber` to wait for a terminal event, which never arrives, or if it arrives, does not find the `streamId` to be valid since the code was invoking `cleanUp()`. This although subtle, but causes memory build up as the `Subscriber` in the case of a server, is the subscriber which is writing the response. If the response does not complete, all state associated with the request is kept alive forever. #### Solution Call `onComplete()` after sending an error frame. This code does not call `cancel()` after `onComplete()` as reactive streams spec does not mandate cancellation post a terminal event, unlike `RxJava`. #### Result No more memory leak! * Review comments --- .../io/reactivesocket/internal/Responder.java | 32 ++++++++++--------- 1 file changed, 17 insertions(+), 15 deletions(-) diff --git a/reactivesocket-core/src/main/java/io/reactivesocket/internal/Responder.java b/reactivesocket-core/src/main/java/io/reactivesocket/internal/Responder.java index 92c7666de..4698b5a1f 100644 --- a/reactivesocket-core/src/main/java/io/reactivesocket/internal/Responder.java +++ b/reactivesocket-core/src/main/java/io/reactivesocket/internal/Responder.java @@ -10,6 +10,7 @@ * an "AS IS" BASIS, WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied.

(#112) * Loadbalancer: Refactor socket/factory Map into Queues + bugfix. **Problem** The loadbalancer uses internally 2 maps, one for the list of `ReactiveSocketFactory` it can use for creating a new `ReactiveSocket`, and one for the active `ReactiveSocket`. The link is made between the 2 maps through the `SocketAddress` of the associated remote server. This is kind of clunky and requires explicit knowledge of the `SocketAddress` (result type of `remote()`). Also, when we select a new factory to connect to or when we select the slowest ReactiveSocket to quick out, the sorting is made via the `sorted()` method on the java stream. The comparison function is actually unstable because a tcp socket can be closed while we do the sorting. **Solution** Use two queues, one for factories and one for ReactiveSocket. Selecting a factory is made using the "Power of 2 Choices" technique, and we also "age" the unselected factories by moving them at the end of the queue. The WeightedSocket now contains a reference to the associated factory, and closing it add back the factory to the factory queue. **Modification** Move the `WeightedSocket` class inside the `LoadBalancer`, no I created a proper constructor to `LoadBalancer` with javadoc explaining all parameters the algorithm requires. The `LatencySubscriber` inside the LoadBalancer treats some exceptions particularly: - `TimeoutException` latency is used for predicating the next latency - `TransportException` & `ClosedChannelException` removes the ReactiveSocket from the active list. `Publishers.onError` now also `cancel` the subscription.

These refactor has some changes that are not necessarily related to local transport but makes the usage better. Modification Refactored common test classes to `reactivesocket-test` module so they can be used in both tcp and local transport without code duplication.

This is illegal according to spec. - Flow control was not properly managed if the error happens after a few emissions. Since we have removed retry functionality from the `ClientBuilder` there is no reason to maintain this code. `Publishers` was not wiring the downstream subscriber cancellation to the cancellation of the `Subscriber`. This means that a cancel followed by `onNext` would not have stopped the emission, which although not necessary (because of the inherent race between cancel and emissions) but is good to have. #### Modification - Removed `RetrySocket` and `Publishers.retry()` since they are not used. - Added (moved from `PublisherUtils`) `.empty()`, `.just()` and `.error()` to `Publishers` - Added `concatEmpty()` to `Publishers`. This is required in places where we concat `Publisher` in custom crafter code. (I will send another PR which is to use this operator in `ReactiveSocket.close()` - Added tests for functions in `Publishers`. --- .../client/filter/RetrySocket.java | 70 ----- .../io/reactivesocket/RequestHandler.java | 5 +- .../internal/CancellableSubscriber.java | 61 +++++ .../internal/PublisherUtils.java | 63 ----- .../reactivesocket/internal/Publishers.java | 248 +++++++----------- .../io/reactivesocket/internal/Responder.java | 12 +- .../internal/SafeCancellableSubscriber.java | 74 ++++++ .../SafeCancellableSubscriberProxy.java | 58 ++++ .../internal/SingleEmissionSubscription.java | 70 +++++ .../io/reactivesocket/ReactiveSocketPerf.java | 4 +- .../internal/PublishersConcatEmptyTest.java | 90 +++++++ .../internal/PublishersMapTest.java | 108 ++++++++ .../PublishersSingleEmissionsTest.java | 56 ++++ .../internal/PublishersTimeoutTest.java | 81 ++++++ 14 files changed, 709 insertions(+), 291 deletions(-) delete mode 100644 reactivesocket-client/src/main/java/io/reactivesocket/client/filter/RetrySocket.java create mode 100644 reactivesocket-core/src/main/java/io/reactivesocket/internal/CancellableSubscriber.java create mode 100644 reactivesocket-core/src/main/java/io/reactivesocket/internal/SafeCancellableSubscriber.java create mode 100644 reactivesocket-core/src/main/java/io/reactivesocket/internal/SafeCancellableSubscriberProxy.java create mode 100644 reactivesocket-core/src/main/java/io/reactivesocket/internal/SingleEmissionSubscription.java create mode 100644 reactivesocket-core/src/test/java/io/reactivesocket/internal/PublishersConcatEmptyTest.java create mode 100644 reactivesocket-core/src/test/java/io/reactivesocket/internal/PublishersMapTest.java create mode 100644 reactivesocket-core/src/test/java/io/reactivesocket/internal/PublishersSingleEmissionsTest.java create mode 100644 reactivesocket-core/src/test/java/io/reactivesocket/internal/PublishersTimeoutTest.java diff --git a/reactivesocket-client/src/main/java/io/reactivesocket/client/filter/RetrySocket.java b/reactivesocket-client/src/main/java/io/reactivesocket/client/filter/RetrySocket.java deleted file mode 100644 index 013b16035..000000000 --- a/reactivesocket-client/src/main/java/io/reactivesocket/client/filter/RetrySocket.java +++ /dev/null @@ -1,70 +0,0 @@ -/** - * Copyright 2016 Netflix, Inc. - * - * Licensed under the Apache License, Version 2.0 (the "License");

Also, it created unnecessary class hierarchy with little benefit. (Edit: Adding more context from the comments below) There were 3 classes CancellableSubscriber, SafeCancellableSubscriber and SafeCancellableSubscriberProxy, each of them would override some of the methods from Subscriber. eg: doOnCancel was something that was to be used by SafeCancellableSubscriber and CancellableSubscriber in a way that SafeCancellableSubscriber had to implement doOnCancel and provide yet another method doOnCancel0 which if implemented by SafeCancellableSubscriberProxy will have to provide yet another protected method. So, I figured not only the approach was error prone it was painful to code and maintain. Thus this approach where in specific callbacks can be overridden and controlled by the caller. Modification Rolled up all implementations into a single class that takes various callbacks as different lambdas. This is easier to use and there are less chances of errors when the implementor forgot to call super methods. Thanks @yschimke for the comment in PR #127 which led me to change the approach. --- .../client/TestingReactiveSocket.java | 24 ++- .../client/TimeoutFactoryTest.java | 18 +- .../internal/CancellableSubscriber.java | 44 +--- .../internal/CancellableSubscriberImpl.java | 149 +++++++++++++ .../reactivesocket/internal/Publishers.java | 193 ++++++----------- .../internal/SafeCancellableSubscriber.java | 74 ------- .../SafeCancellableSubscriberProxy.java | 58 ----- .../reactivesocket/internal/Subscribers.java | 201 ++++++++++++++++++ .../internal/Subscriptions.java | 111 ++++++++++ .../internal/SubscriberRule.java | 129 +++++++++++ .../internal/SubscribersCreateTest.java | 87 ++++++++ .../SubscribersDoOnSubscriberTest.java | 68 ++++++ 12 files changed, 840 insertions(+), 316 deletions(-) create mode 100644 reactivesocket-core/src/main/java/io/reactivesocket/internal/CancellableSubscriberImpl.java delete mode 100644 reactivesocket-core/src/main/java/io/reactivesocket/internal/SafeCancellableSubscriber.java delete mode 100644 reactivesocket-core/src/main/java/io/reactivesocket/internal/SafeCancellableSubscriberProxy.java create mode 100644 reactivesocket-core/src/main/java/io/reactivesocket/internal/Subscribers.java create mode 100644 reactivesocket-core/src/main/java/io/reactivesocket/internal/Subscriptions.java create mode 100644 reactivesocket-core/src/test/java/io/reactivesocket/internal/SubscriberRule.java create mode 100644 reactivesocket-core/src/test/java/io/reactivesocket/internal/SubscribersCreateTest.java create mode 100644 reactivesocket-core/src/test/java/io/reactivesocket/internal/SubscribersDoOnSubscriberTest.java diff --git a/reactivesocket-client/src/test/java/io/reactivesocket/client/TestingReactiveSocket.java b/reactivesocket-client/src/test/java/io/reactivesocket/client/TestingReactiveSocket.java index 6edd1f6fc..3847ecb58 100644 --- a/reactivesocket-client/src/test/java/io/reactivesocket/client/TestingReactiveSocket.java +++ b/reactivesocket-client/src/test/java/io/reactivesocket/client/TestingReactiveSocket.java @@ -9,15 +9,24 @@ import org.reactivestreams.Subscription;

(#141) * `ClientBuilder.build` is now asynchronous. ***Problem*** The ClientBuilder `build` API return a ReactiveSocket. This ReactiveSocket is returned while connections are still in establishing mode, then it will fail until the connections established. The current solution is to call `Unsafe.awaitAvailability` which is cluncky. ***Solution*** Create a more robust API that return a `Publisher`, it is now obvious that the API is asynchronous. ***Modification*** I found a bug in `sourceToFactory`, where I was calling `subscriber.onSubscribe` before initializing the `current` Map. --- .../reactivesocket/client/ClientBuilder.java | 71 ++++++++++++++----- .../client/ClientBuilderTest.java | 71 +++++++++++++++++++ .../reactivesocket/examples/StressTest.java | 4 +- 3 files changed, 126 insertions(+), 20 deletions(-) create mode 100644 reactivesocket-client/src/test/java/io/reactivesocket/client/ClientBuilderTest.java diff --git a/reactivesocket-client/src/main/java/io/reactivesocket/client/ClientBuilder.java b/reactivesocket-client/src/main/java/io/reactivesocket/client/ClientBuilder.java index 563aba477..c0d9cf921 100644 --- a/reactivesocket-client/src/main/java/io/reactivesocket/client/ClientBuilder.java +++ b/reactivesocket-client/src/main/java/io/reactivesocket/client/ClientBuilder.java @@ -23,7 +23,9 @@ import java.util.*;

This is fine when the budget is far greater than the number of clients, but in the opposite situation, it leads to client starving, as the budget is always distributed in the same order. ***Solution*** Shuffle the list of client prior to distributing the budget. --- .../java/io/reactivesocket/lease/FairLeaseGovernor.java | 7 ++++--- 1 file changed, 4 insertions(+), 3 deletions(-) diff --git a/reactivesocket-core/src/main/java/io/reactivesocket/lease/FairLeaseGovernor.java b/reactivesocket-core/src/main/java/io/reactivesocket/lease/FairLeaseGovernor.java index 1376b73c7..65637b7ec 100644 --- a/reactivesocket-core/src/main/java/io/reactivesocket/lease/FairLeaseGovernor.java +++ b/reactivesocket-core/src/main/java/io/reactivesocket/lease/FairLeaseGovernor.java @@ -19,8 +19,7 @@ import io.reactivesocket.LeaseGovernor; import io.reactivesocket.internal.Responder; -import java.util.HashMap; -import java.util.Map; +import java.util.*; import java.util.concurrent.Executors; import java.util.concurrent.ScheduledExecutorService; import java.util.concurrent.ScheduledFuture; @@ -44,7 +43,9 @@ private synchronized void distribute(int ttlMs) { // it would be more fair to randomized the distribution of extra int extra = tickets - budget * responders.size(); - for (Responder responder: responders.keySet()) { + List clients = new ArrayList<>(responders.keySet());; + Collections.shuffle(clients); + for (Responder responder: clients) { int n = budget; if (extra > 0) { n += 1; From 91c0858a9b2c4cc5ad642b2740fff8ec35b4c40c Mon Sep 17 00:00:00 2001 From: Yuri Schimke Date: Wed, 27 Jul 2016 17:14:16 +0100 Subject: [PATCH 167/950] Add hexstring tests for frame header encoding (#104) * move setup flags 2 bytes to the left * unit test frame headers * reformat --- reactivesocket-core/build.gradle | 1 + .../java/io/reactivesocket/FrameTest.java | 234 +++++++++--------- 2 files changed, 124 insertions(+), 111 deletions(-) diff --git a/reactivesocket-core/build.gradle b/reactivesocket-core/build.gradle index 60fb959de..1d7bce7b9 100644 --- a/reactivesocket-core/build.gradle +++ b/reactivesocket-core/build.gradle @@ -1,3 +1,4 @@ dependencies { testCompile 'io.reactivex:rxjava:2.0.0-DP0-20151003.214425-143' + testCompile 'io.netty:netty-codec-http:4.1.0.Final' } \ No newline at end of file diff --git a/reactivesocket-core/src/test/java/io/reactivesocket/FrameTest.java b/reactivesocket-core/src/test/java/io/reactivesocket/FrameTest.java index 5ee274b4c..4b3cfa684 100644 --- a/reactivesocket-core/src/test/java/io/reactivesocket/FrameTest.java +++ b/reactivesocket-core/src/test/java/io/reactivesocket/FrameTest.java @@ -1,12 +1,12 @@ /** * Copyright 2015 Netflix, Inc. - * + *

In order to provide a truly polyglot solution, we determined that the best way to do so was to provide a central +TCK repository with only the code that generates the intermediate script, and then leave it up to implementers to create the +drivers for their own implementation. The script was created specifically to be easy to parse and implement drivers for, +and this Java driver is the first driver to be created as the Java implementation of ReactiveSockets is the most mature at +the time. + +The driver is organized with a simple structure. On both the client and server drivers, we have the main driver class that +do an intial parse of the script files. On the server side, this process basically constructs dynamic request handlers where +every time a request is received, the appropriate behavior is searched up and is passed to a ParseMarble object, which is run +on its own thread and is used to parse through a marble diagram and enact it's behavior. On the client side, the main driver +class splits up each test into it's own individual lines, and then runs each test synchronously in its own thread. Support +for concurrent behavior can easily be added later. + +On the client side, for the most part, each test thread just parses through each line of the test in order, synchronously and enacts its +behavior on our TestSubscriber, a special subscriber that we can use to verify that certain things have happened. `await` calls +should block the main test thread, and the test should fail if a single assert fails. + +Things get trickier with channel tests, because the client and server need to have the same behavior. In channel tests on both +sides, the driver creates a ParseChannel object, which parses through the contents of a channel tests and handles receiving +and sending data. We use the ParseMarble object to handle sending data. Here, we have one thread that continuously runs `parse()`, +and other threads that run `add()` and `request()`, which stages data to be added and requested. + + + +## Run Instructions + +You can build the project with `gradle build`. +You can run the client and server using the `run` script with `./run [options]`.

` : If launching as client, tells it to connect to port `p`, and if launching as server, tells what port to server on + +`--file ` : The path to the script file.

In order to + * achieve that, this class provides the following contracts: + * + *

    + *
  • A {@link Publisher} that can be written to a {@code DuplexConnection} using + {@link DuplexConnection#send(Publisher)}

  • A {@link Subscriber} that subscribes to the original data {@code Publisher}
    • + *
  • A {@link Subscription} that can be used to accept cancellations and flow control, typically from the peer of the + * {@code ReactiveSocket}.
    • + *
+ * + *

Subscriptions

+ * + * Logically there are two subscriptions to this {@code Processor}. One from {@link DuplexConnection#send(Publisher)} + * and other logical subscription from the peer of the {@code ReactiveSocket} this stream is sent to. + * The {@link Subscription} contract on this class is to receive {@code Subscription} signals from the remote peer i.e. + * typically via a {@code RequestN} and {@code Cancel} frames. However, cancellations may be used to signal a cancel of + * the write, typically due to clean shutdown of the associated {@code ReactiveSocket}. + * + *

Flow Control

+ * + * This class mediates between the flow control between the transport and {@code ReactiveSocket} peer, so + * to make sure that a higher demand from transport does not overwrite lower demand from the peer and vice-versa. + * This feature is different than a regular {@link Processor}. + * + *

Flow control with terminal events

In order to provide a truly polyglot solution, we determined that the best way to do so was to provide a central -TCK repository with only the code that generates the intermediate script, and then leave it up to implementers to create the -drivers for their own implementation. The script was created specifically to be easy to parse and implement drivers for, -and this Java driver is the first driver to be created as the Java implementation of ReactiveSockets is the most mature at -the time. - -The driver is organized with a simple structure. On both the client and server drivers, we have the main driver class that -do an intial parse of the script files. On the server side, this process basically constructs dynamic request handlers where -every time a request is received, the appropriate behavior is searched up and is passed to a ParseMarble object, which is run -on its own thread and is used to parse through a marble diagram and enact it's behavior. On the client side, the main driver -class splits up each test into it's own individual lines, and then runs each test synchronously in its own thread. Support -for concurrent behavior can easily be added later. - -On the client side, for the most part, each test thread just parses through each line of the test in order, synchronously and enacts its -behavior on our TestSubscriber, a special subscriber that we can use to verify that certain things have happened. `await` calls -should block the main test thread, and the test should fail if a single assert fails. - -Things get trickier with channel tests, because the client and server need to have the same behavior. In channel tests on both -sides, the driver creates a ParseChannel object, which parses through the contents of a channel tests and handles receiving -and sending data. We use the ParseMarble object to handle sending data. Here, we have one thread that continuously runs `parse()`, -and other threads that run `add()` and `request()`, which stages data to be added and requested. - - - -## Run Instructions - -You can build the project with `gradle build`. -You can run the client and server using the `run` script with `./run [options]`. The options are: - -`--server` : This is if you want to launch the server - -`--client` : This is if you want to launch the client - -`--host ` : This is for the client only, determines what host to connect to - -`--port

` : If launching as client, tells it to connect to port `p`, and if launching as server, tells what port to server on - -`--file ` : The path to the script file. Make sure to give the server and client the correct file formats - -`--debug` : This is if you want to look at the individual frames being sent and received by the client - -`--tests` : This allows you, when you're running the client, to specify the tests you want to run by name. Each test -should be comma separated. - -Examples: -`./run.sh --server --port 4567 --file src/test/resources/servertest.txt` should start up a server on port `4567` that -has its behavior determined by the file `servertest.txt`. - -`./run.sh --client --host localhost --port 4567 --file src/test/resources/clienttest.txt --debug --tests genericTest,badTest` should -start the client and have it connect to localhost on port `4567` and load the tests in `clienttest.txt` in debug mode, -and only run the tests named `genericTest` and `badTest`. - diff --git a/reactivesocket-tck-drivers/build.gradle b/reactivesocket-tck-drivers/build.gradle deleted file mode 100644 index 3944f082a..000000000 --- a/reactivesocket-tck-drivers/build.gradle +++ /dev/null @@ -1,35 +0,0 @@ -apply plugin: 'application' -apply plugin: 'java' - -mainClassName = "io.reactivesocket.tckdrivers.main.Main" - -jar { - manifest { - attributes "Main-Class": "$mainClassName" - } - - from { - configurations.compile.collect { it.isDirectory() ? it : zipTree(it) } - } -} - -dependencies { - - compile project(':reactivesocket-core') - compile project(':reactivesocket-client') - compile project(':reactivesocket-transport-tcp') - testCompile project(':reactivesocket-test') - compile 'com.fasterxml.jackson.core:jackson-core:2.8.0.rc2' - compile 'com.fasterxml.jackson.core:jackson-databind:2.8.0.rc2' - compile 'org.apache.commons:commons-lang3:3.4' - compile 'io.reactivex:rxjava-reactive-streams:1.1.0"' - compile 'io.airlift:airline:0.7' -} - -task runTests(type: JavaExec) { - classpath(sourceSets.main.runtimeClasspath, sourceSets.main.compileClasspath) - main = 'io.reactivesocket.tckdrivers.main.TestMain' - args '--port', '4567', '--serverfile', 'src/test/resources/server$.txt', '--clientfile', 'src/test/resources/client$.txt' -} - -build.dependsOn runTests \ No newline at end of file diff --git a/reactivesocket-tck-drivers/run.sh b/reactivesocket-tck-drivers/run.sh deleted file mode 100755 index 62ff4fde9..000000000 --- a/reactivesocket-tck-drivers/run.sh +++ /dev/null @@ -1,7 +0,0 @@ -#!/bin/bash - -LATEST_VERSION=$(ls build/libs/reactivesocket-tck-drivers-*-SNAPSHOT.jar | sort -r | head -1) - -echo "running latest version $LATEST_VERSION" - -java -cp "$LATEST_VERSION" io.reactivesocket.tckdrivers.main.Main "$@" diff --git a/reactivesocket-tck-drivers/src/main/java/io/reactivesocket/tckdrivers/client/JavaClientDriver.java b/reactivesocket-tck-drivers/src/main/java/io/reactivesocket/tckdrivers/client/JavaClientDriver.java deleted file mode 100644 index 2e17d3257..000000000 --- a/reactivesocket-tck-drivers/src/main/java/io/reactivesocket/tckdrivers/client/JavaClientDriver.java +++ /dev/null @@ -1,570 +0,0 @@ -/* - * Copyright 2016 Facebook, Inc. - *

Since, leases come on stream 0, clients were not receiving the leases. #### Modification Modified `ClientServerInputMultiplexer` to send stream 0 frames to both sockets (since both ends receive frames on stream 0) and let them decide which ones are useful for them. Also modified `FairLeaseDistributor` to subscribe to ticks after the first socket is registered. This provides predictable behavior w.r.t the first lease distribution i.e. if the lease ticks start on subscription, generally the first lease is missed by the first socket. #### Result Clients now receive leases. --- .../reactivesocket/ServerReactiveSocket.java | 2 +- .../ClientServerInputMultiplexer.java | 5 +++- .../lease/FairLeaseDistributor.java | 30 ++++++++++++++----- 3 files changed, 27 insertions(+), 10 deletions(-) diff --git a/reactivesocket-core/src/main/java/io/reactivesocket/ServerReactiveSocket.java b/reactivesocket-core/src/main/java/io/reactivesocket/ServerReactiveSocket.java index f37ea41a6..832810469 100644 --- a/reactivesocket-core/src/main/java/io/reactivesocket/ServerReactiveSocket.java +++ b/reactivesocket-core/src/main/java/io/reactivesocket/ServerReactiveSocket.java @@ -183,7 +183,7 @@ private Publisher handleFrame(Frame frame) { case METADATA_PUSH: return metadataPush(frame); case LEASE: - //TODO: Handle leasing + // Lease must not be received here as this is the server end of the socket which sends leases. return Px.empty(); case NEXT: synchronized (channelProcessors) { diff --git a/reactivesocket-core/src/main/java/io/reactivesocket/internal/ClientServerInputMultiplexer.java b/reactivesocket-core/src/main/java/io/reactivesocket/internal/ClientServerInputMultiplexer.java index b773da5d5..5900719c6 100644 --- a/reactivesocket-core/src/main/java/io/reactivesocket/internal/ClientServerInputMultiplexer.java +++ b/reactivesocket-core/src/main/java/io/reactivesocket/internal/ClientServerInputMultiplexer.java @@ -98,7 +98,10 @@ public void onSubscribe(Subscription s) { @Override public void onNext(Frame frame) { - if (BitUtil.isEven(frame.getStreamId())) { + if (frame.getStreamId() == 0) { + evenSubscription.safeOnNext(frame); + oddSubscription.safeOnNext(frame); + } else if (BitUtil.isEven(frame.getStreamId())) { evenSubscription.safeOnNext(frame); } else { oddSubscription.safeOnNext(frame); diff --git a/reactivesocket-core/src/main/java/io/reactivesocket/lease/FairLeaseDistributor.java b/reactivesocket-core/src/main/java/io/reactivesocket/lease/FairLeaseDistributor.java index 720feeda4..38a8d6b20 100644 --- a/reactivesocket-core/src/main/java/io/reactivesocket/lease/FairLeaseDistributor.java +++ b/reactivesocket-core/src/main/java/io/reactivesocket/lease/FairLeaseDistributor.java @@ -36,20 +36,17 @@ public final class FairLeaseDistributor implements DefaultLeaseEnforcingSocket.L private final LinkedBlockingQueue> activeRecipients; private Subscription ticksSubscription; + private volatile boolean startTicks; + private final IntSupplier capacitySupplier; private final int leaseTTL; + private final Publisher leaseDistributionTicks; private volatile int remainingPermits; public FairLeaseDistributor(IntSupplier capacitySupplier, int leaseTTL, Publisher leaseDistributionTicks) { + this.capacitySupplier = capacitySupplier; this.leaseTTL = leaseTTL; + this.leaseDistributionTicks = leaseDistributionTicks; activeRecipients = new LinkedBlockingQueue<>(); - Px.from(leaseDistributionTicks) - .doOnSubscribe(subscription -> ticksSubscription = subscription) - .doOnNext(aLong -> { - remainingPermits = capacitySupplier.getAsInt(); - distribute(remainingPermits); - }) - .ignore() - .subscribe(); } /** @@ -71,6 +68,12 @@ public void shutdown() { @Override public Cancellable registerSocket(Consumer leaseConsumer) { activeRecipients.add(leaseConsumer); + synchronized (this) { + if (!startTicks) { + startTicks(); + startTicks = true; + } + } return new CancellableImpl() { @Override protected void onCancel() { @@ -101,4 +104,15 @@ private void distribute(int permits) { recipient.accept(leaseToSend); } } + + private void startTicks() { + Px.from(leaseDistributionTicks) + .doOnSubscribe(subscription -> ticksSubscription = subscription) + .doOnNext(aLong -> { + remainingPermits = capacitySupplier.getAsInt(); + distribute(remainingPermits); + }) + .ignore() + .subscribe(); + } } From 311542a39e8a95782753abebc9c4f8a18b0a130e Mon Sep 17 00:00:00 2001 From: Nitesh Kant Date: Mon, 24 Oct 2016 15:45:05 -0700 Subject: [PATCH 177/950] Payload support for`SetupProvider` #### Problem `SetupProvider` currently does not provide a way to specify data and metadata for the setup frame. #### Modification Add a method `setupPayload(Payload)` to support optionally specifying a payload for the setup frame.

Today server sends leases even though the client does not honor leases. There are two things here: - A server should protect itself, even if the client dishonors leases, i.e. leases aren't infinite if the client does not honor. So, the server should still expect requests within capacity from clients and reject all other requests. - Clients should not receive lease frames as they are not relevant. Modified `ServerReactiveSocket` to not send leases when the setup is such that client does not honor leases. Also, added an override in `SetupProvider` to be able to modify the `DisableLeaseSocket` if required. Expected results and optimizations on the wire w.r.t data transfers. --- .../reactivesocket/ServerReactiveSocket.java | 15 ++- .../reactivesocket/client/SetupProvider.java | 10 ++ .../client/SetupProviderImpl.java | 12 +- .../lease/DisableLeaseSocket.java | 9 +- .../io/reactivesocket/lease/LeaseImpl.java | 9 ++ .../server/ReactiveSocketServer.java | 1 + .../local/internal/PeerConnector.java | 9 +- .../ClientDishonorLeaseTest.java | 107 ++++++++++++++++++ .../local/LocalSendReceiveTest.java | 22 ++-- 9 files changed, 168 insertions(+), 26 deletions(-) create mode 100644 reactivesocket-transport-local/src/test/java/io/reactivesocket/ClientDishonorLeaseTest.java diff --git a/reactivesocket-core/src/main/java/io/reactivesocket/ServerReactiveSocket.java b/reactivesocket-core/src/main/java/io/reactivesocket/ServerReactiveSocket.java index 832810469..fdefcc34e 100644 --- a/reactivesocket-core/src/main/java/io/reactivesocket/ServerReactiveSocket.java +++ b/reactivesocket-core/src/main/java/io/reactivesocket/ServerReactiveSocket.java @@ -52,9 +52,8 @@ public class ServerReactiveSocket implements ReactiveSocket { private final ReactiveSocket requestHandler;

(#185) * `RemoteReceiver` handle events before subscription. #### Problem `RemoteReceiver` is used for receiving a stream over a `ReactiveSocket`, eg: `requestChannel()` request stream or `requestStream()` response. For request stream, it may so happen that the receiver does not subscribe to the request stream. This is OK for `onNext`s but terminal events can flow in without explicit `requestN`s. `RemoteReceiver` does not handle such terminal events today. #### Modification Added `missedCompletion` and `missedError` to `RemoteReceiver` that correctly buffers the terminal events if there is no subscription and sends these events if and when a subscriber arrives. #### Result No errors when terminal events flow without subscription. * Review comments Fixed a concurrency bug in `RemoteReceiver` as discussed in this comment: https://github.com/ReactiveSocket/reactivesocket-java/pull/185#discussion_r86440259 --- .../internal/RemoteReceiver.java | 94 +++++++++++-------- .../internal/RemoteReceiverTest.java | 24 ++++- .../internal/ValidatingSubscription.java | 14 +++ 3 files changed, 94 insertions(+), 38 deletions(-) diff --git a/reactivesocket-core/src/main/java/io/reactivesocket/internal/RemoteReceiver.java b/reactivesocket-core/src/main/java/io/reactivesocket/internal/RemoteReceiver.java index 77e16df09..f4624c3bb 100644 --- a/reactivesocket-core/src/main/java/io/reactivesocket/internal/RemoteReceiver.java +++ b/reactivesocket-core/src/main/java/io/reactivesocket/internal/RemoteReceiver.java @@ -53,7 +53,6 @@ */ public final class RemoteReceiver implements Processor { - private final Publisher transportSource;

Fixed stream and channel methods to work end to end. Also added examples for the same. They are now implemented using the existing `RemoteReceiver` and `RemoteSender` classes. One major problem with using `ConnectableUnicastProcessor` was that it does not discriminate between subscriber of request and sender of `requestN` and `cancel` frames. So, if the request source is completed, sending `requestN` and `cancel` frames result in them being rejected by the transport. This is one of the reasons `RemoteReceiver` and `RemoteSender` classes were created. __ request-response implementation is not changed in this change as that needs to be optimized for a single item request-response__ Channel and stream work now. --- .../reactivesocket/ClientReactiveSocket.java | 159 ++++++++++-------- .../main/java/io/reactivesocket/Frame.java | 13 +- .../reactivesocket/ServerReactiveSocket.java | 12 +- .../internal/RemoteReceiver.java | 17 +- reactivesocket-examples/build.gradle | 2 + .../tcp/channel/ChannelEchoClient.java | 79 +++++++++ .../requestresponse}/HelloWorldClient.java | 2 +- .../transport/tcp/stream/StreamingClient.java | 72 ++++++++ .../src/main/resources/log4j.properties | 2 +- .../integration}/StressTest.java | 23 ++- .../ConnectableUnicastProcessor.java | 16 +- 11 files changed, 301 insertions(+), 96 deletions(-) create mode 100644 reactivesocket-examples/src/main/java/io/reactivesocket/examples/transport/tcp/channel/ChannelEchoClient.java rename reactivesocket-examples/src/main/java/io/reactivesocket/examples/{helloworld => transport/tcp/requestresponse}/HelloWorldClient.java (97%) create mode 100644 reactivesocket-examples/src/main/java/io/reactivesocket/examples/transport/tcp/stream/StreamingClient.java rename reactivesocket-examples/src/{main/java/io/reactivesocket/examples => test/java/io/reactivesocket/integration}/StressTest.java (93%) diff --git a/reactivesocket-core/src/main/java/io/reactivesocket/ClientReactiveSocket.java b/reactivesocket-core/src/main/java/io/reactivesocket/ClientReactiveSocket.java index 2209429d6..05f88ea1a 100644 --- a/reactivesocket-core/src/main/java/io/reactivesocket/ClientReactiveSocket.java +++ b/reactivesocket-core/src/main/java/io/reactivesocket/ClientReactiveSocket.java @@ -20,10 +20,13 @@ import io.reactivesocket.exceptions.CancelException;

This creates choppy metrics. Modifications Modified the timer to have n histrograms in a queue and rotate of over them to smooth out the histogram over a sliding window. Switched the dimensions of the histrogram to a label called value. Switched the reseting of the histrogram to a closure that is called by the timer instead so it will rotate the histrogram once per window. Result Correct metrics over a rolling window. --- .../servo/internal/HdrHistogramGauge.java | 22 ++--- .../servo/internal/HdrHistogramMaxGauge.java | 6 +- .../servo/internal/HdrHistogramMinGauge.java | 6 +- .../internal/HdrHistogramServoTimer.java | 52 +++++----- .../internal/SlidingWindowHistogram.java | 95 +++++++++++++++++++ .../internal/SlidingWindowHistogramTest.java | 62 ++++++++++++ 6 files changed, 198 insertions(+), 45 deletions(-) create mode 100644 reactivesocket-stats-servo/src/main/java/io/reactivesocket/loadbalancer/servo/internal/SlidingWindowHistogram.java create mode 100644 reactivesocket-stats-servo/src/test/java/io/reactivesocket/loadbalancer/servo/internal/SlidingWindowHistogramTest.java diff --git a/reactivesocket-stats-servo/src/main/java/io/reactivesocket/loadbalancer/servo/internal/HdrHistogramGauge.java b/reactivesocket-stats-servo/src/main/java/io/reactivesocket/loadbalancer/servo/internal/HdrHistogramGauge.java index d06e97f2f..a50ba6f93 100644 --- a/reactivesocket-stats-servo/src/main/java/io/reactivesocket/loadbalancer/servo/internal/HdrHistogramGauge.java +++ b/reactivesocket-stats-servo/src/main/java/io/reactivesocket/loadbalancer/servo/internal/HdrHistogramGauge.java @@ -21,37 +21,27 @@ import com.netflix.servo.monitor.NumberGauge;

Otherwise, the frame is treated as `COMPLETE`. This is a problem for request-response as this means the response publisher will complete without emitting a response, if the response does not have any data. Such a condition is a failure as request-response should have exaclty one response. #### Modification Eliminated the check for data length and always emit `NEXT_COMPLETE` if the complete flag is set. According to the [protocol](https://github.com/ReactiveSocket/reactivesocket/blob/master/Protocol.md#response-frame): ``` A Response is generally referred to as a NEXT. ``` So, this behavior would not be a violation of the protocol but will produce empty `onNext` before `onComplete` #### Result Better behavior with empty responses. --- .../frame/FrameHeaderFlyweight.java | 15 ++++++--------- .../io/reactivesocket/internal/RemoteSender.java | 9 +++++++-- .../reactivesocket/ServerReactiveSocketTest.java | 7 +++---- .../reactivesocket/internal/RemoteSenderTest.java | 4 ++-- .../tcp/requestresponse/HelloWorldClient.java | 4 ++-- 5 files changed, 20 insertions(+), 19 deletions(-) diff --git a/reactivesocket-core/src/main/java/io/reactivesocket/frame/FrameHeaderFlyweight.java b/reactivesocket-core/src/main/java/io/reactivesocket/frame/FrameHeaderFlyweight.java index 8c5572f67..49e1f3052 100644 --- a/reactivesocket-core/src/main/java/io/reactivesocket/frame/FrameHeaderFlyweight.java +++ b/reactivesocket-core/src/main/java/io/reactivesocket/frame/FrameHeaderFlyweight.java @@ -148,8 +148,8 @@ public static int encode( final int frameLength = computeFrameHeaderLength(frameType, metadata.remaining(), data.remaining());

Instead one has to use ```java Flowable.fromPublisher(Flowable.defer(() -> socket.requestResponse(PayloadImpl.EMPTY))) ``` The reason is that the implementation creates a `streamId` upon calling `requestResponse` and not on each subscription. __Modification__ Modify `ClientReactiveSocket` to create a new `streamId` per subscription. This will make sure that each subscription is unique and hence a server will not have an issue accepting such requests. __Result__ More idiomatic usage of function composition and retry/repeat kind of models. --- .../reactivesocket/ClientReactiveSocket.java | 173 +++++++++--------- .../ClientReactiveSocketTest.java | 35 ++-- .../tcp/requestresponse/HelloWorldClient.java | 4 +- 3 files changed, 107 insertions(+), 105 deletions(-) diff --git a/reactivesocket-core/src/main/java/io/reactivesocket/ClientReactiveSocket.java b/reactivesocket-core/src/main/java/io/reactivesocket/ClientReactiveSocket.java index 05f88ea1a..6a7b33bd1 100644 --- a/reactivesocket-core/src/main/java/io/reactivesocket/ClientReactiveSocket.java +++ b/reactivesocket-core/src/main/java/io/reactivesocket/ClientReactiveSocket.java @@ -27,11 +27,9 @@ import io.reactivesocket.reactivestreams.extensions.DefaultSubscriber; import io.reactivesocket.reactivestreams.extensions.Px; import io.reactivesocket.reactivestreams.extensions.internal.ValidatingSubscription; -import io.reactivesocket.reactivestreams.extensions.internal.processors.ConnectableUnicastProcessor; import io.reactivesocket.reactivestreams.extensions.internal.subscribers.CancellableSubscriber; import io.reactivesocket.reactivestreams.extensions.internal.subscribers.Subscribers; import org.agrona.collections.Int2ObjectHashMap; -import org.reactivestreams.Processor; import org.reactivestreams.Publisher; import org.reactivestreams.Subscriber; import org.reactivestreams.Subscription; @@ -40,7 +38,7 @@ import java.nio.charset.StandardCharsets; import java.util.function.Consumer; -import static io.reactivesocket.reactivestreams.extensions.internal.subscribers.Subscribers.doOnError; +import static io.reactivesocket.reactivestreams.extensions.internal.subscribers.Subscribers.*; /** * Client Side of a ReactiveSocket socket.

It only contains the core interfaces to support event publications from `ReactiveSocket` internals. The model is adopted from the tried and tested model in `RxNetty` to provide an event publishing infrastructure that can be used to implement metrics of event firehose. One of the primary guideline of this model is to reduce the object allocations that comes along with an event stream based on emitting an event as an object. Instead, this approach embraces distinct callbacks that any listener can choose to implement if interested. Primary classes are `EventListener` and `EventSource`. There are a few extensions of `EventListener` to provide events specific to a server, client or load balancer. __Result__ Better insight into `ReactiveSocket` internals. --- .../events/LoadBalancingClientListener.java | 82 ++++++ .../events/ClientEventListener.java | 46 ++++ .../reactivesocket/events/EventListener.java | 235 ++++++++++++++++++ .../io/reactivesocket/events/EventSource.java | 45 ++++ .../events/ServerEventListener.java | 29 +++ 5 files changed, 437 insertions(+) create mode 100644 reactivesocket-client/src/main/java/io/reactivesocket/client/events/LoadBalancingClientListener.java create mode 100644 reactivesocket-core/src/main/java/io/reactivesocket/events/ClientEventListener.java create mode 100644 reactivesocket-core/src/main/java/io/reactivesocket/events/EventListener.java create mode 100644 reactivesocket-core/src/main/java/io/reactivesocket/events/EventSource.java create mode 100644 reactivesocket-core/src/main/java/io/reactivesocket/events/ServerEventListener.java diff --git a/reactivesocket-client/src/main/java/io/reactivesocket/client/events/LoadBalancingClientListener.java b/reactivesocket-client/src/main/java/io/reactivesocket/client/events/LoadBalancingClientListener.java new file mode 100644 index 000000000..3ebe31cac --- /dev/null +++ b/reactivesocket-client/src/main/java/io/reactivesocket/client/events/LoadBalancingClientListener.java @@ -0,0 +1,82 @@ +/* + * Copyright 2016 Netflix, Inc. + *

These implementations are somewhat not recognized inside Netflix and hence does not get published to our metrics system. At this point it is better to use the native counterparts than to debug the issue, we can revert to the custom implementation when we see performance issues. __Modification__ Replace custom usages with native spectator classes. __Result__ Metrics correctly published. --- .../spectator/ClientEventListenerImpl.java | 47 +++++----- .../spectator/EventListenerImpl.java | 16 ++-- .../LoadBalancingClientListenerImpl.java | 24 ++--- .../spectator/internal/ErrorStats.java | 38 ++++---- .../spectator/internal/LeaseStats.java | 23 +++-- .../spectator/internal/RequestStats.java | 89 ++++++++++--------- .../spectator/internal/SpectatorUtil.java | 11 ++- 7 files changed, 128 insertions(+), 120 deletions(-) diff --git a/reactivesocket-spectator/src/main/java/io/reactivesocket/spectator/ClientEventListenerImpl.java b/reactivesocket-spectator/src/main/java/io/reactivesocket/spectator/ClientEventListenerImpl.java index d4ee64572..ceffa4e89 100644 --- a/reactivesocket-spectator/src/main/java/io/reactivesocket/spectator/ClientEventListenerImpl.java +++ b/reactivesocket-spectator/src/main/java/io/reactivesocket/spectator/ClientEventListenerImpl.java @@ -13,38 +13,39 @@ package io.reactivesocket.spectator;

(#227) __Problem__ There are the following issues: - `removeSocket()` was not subscribing to `socket.close()`. Since, `close()` is lazy, not subscribing will not close the socket. - Socket is not removed when it closes, unless a request is made to it. - `refreshSocket()` only gets called when making a request. This means that if a client awaits `availability()` when load balancer does not have any active sockets (`NoAvailableHostException`), it is a deadlock as load balancer will never add a socket if there are no requests. __Modification__ - Subscribe to `socket.close()` - Added a `onClose()` listener that removes the socket from the active list when it closes. - Call `refreshSockets()` in `removeSocket()` __ Result__ No deadlock when awaiting availability as a reaction to `NoAvailableHostException`. Actively closed socket from LB actually gets closed. --- .../io/reactivesocket/client/LoadBalancer.java | 15 ++++++++++----- 1 file changed, 10 insertions(+), 5 deletions(-) diff --git a/reactivesocket-client/src/main/java/io/reactivesocket/client/LoadBalancer.java b/reactivesocket-client/src/main/java/io/reactivesocket/client/LoadBalancer.java index f313a1f9c..a92e9e6ad 100644 --- a/reactivesocket-client/src/main/java/io/reactivesocket/client/LoadBalancer.java +++ b/reactivesocket-client/src/main/java/io/reactivesocket/client/LoadBalancer.java @@ -29,6 +29,7 @@ import io.reactivesocket.reactivestreams.extensions.Px; import io.reactivesocket.reactivestreams.extensions.internal.EmptySubject; import io.reactivesocket.reactivestreams.extensions.internal.ValidatingSubscription; +import io.reactivesocket.reactivestreams.extensions.internal.subscribers.Subscribers; import io.reactivesocket.stat.Ewma; import io.reactivesocket.stat.FrugalQuantile; import io.reactivesocket.stat.Median; @@ -388,16 +389,19 @@ private synchronized void quickSlowestRS() { } if (slowest != null) { - removeSocket(slowest); + removeSocket(slowest, false); } } - private synchronized void removeSocket(WeightedSocket socket) { + private synchronized void removeSocket(WeightedSocket socket, boolean refresh) { try { logger.debug("Removing socket: -> " + socket); activeSockets.remove(socket); activeFactories.add(socket.getFactory()); - socket.close(); + socket.close().subscribe(Subscribers.empty()); + if (refresh) { + refreshSockets(); + } } catch (Exception e) { logger.warn("Exception while closing a ReactiveSocket", e); } @@ -786,6 +790,7 @@ private class WeightedSocket extends ReactiveSocketProxy implements LoadBalancer this.median = new Median(); this.interArrivalTime = new Ewma(1, TimeUnit.MINUTES, DEFAULT_INITIAL_INTER_ARRIVAL_TIME); this.pendingStreams = new AtomicLong(); + child.onClose().subscribe(Subscribers.doOnTerminate(() -> removeSocket(this, true))); } WeightedSocket( @@ -997,7 +1002,7 @@ public void onError(Throwable t) { child.onError(t); long now = decr(start); if (t instanceof TransportException || t instanceof ClosedChannelException) { - removeSocket(socket); + removeSocket(socket, true); } else if (t instanceof TimeoutException) { observe(now - start); } @@ -1043,7 +1048,7 @@ public void onError(Throwable t) { socket.pendingStreams.decrementAndGet(); child.onError(t); if (t instanceof TransportException || t instanceof ClosedChannelException) { - removeSocket(socket); + removeSocket(socket, true); } } From 441028a9c982f86b2da9d4bfb107275acffbf7d0 Mon Sep 17 00:00:00 2001 From: Nitesh Kant Date: Fri, 27 Jan 2017 10:57:30 -0800 Subject: [PATCH 219/950] Missed moving to native spectator counter.

is meant to be used in conjunction with the TCK at [reactivesocket-tck](https://github.com/ReactiveSocket/reactivesocket-tck) + +## Basic Idea and Organization + +The philosophy behind the TCK is that it should allow any implementation of ReactiveSocket to verify itself against any other +implementation. In order to provide a truly polyglot solution, we determined that the best way to do so was to provide a central +TCK repository with only the code that generates the intermediate script, and then leave it up to implementers to create the +drivers for their own implementation. The script was created specifically to be easy to parse and implement drivers for, +and this Java driver is the first driver to be created as the Java implementation of ReactiveSockets is the most mature at +the time. + +The driver is organized with a simple structure. On both the client and server drivers, we have the main driver class that +do an intial parse of the script files. On the server side, this process basically constructs dynamic request handlers where +every time a request is received, the appropriate behavior is searched up and is passed to a ParseMarble object, which is run +on its own thread and is used to parse through a marble diagram and enact it's behavior. On the client side, the main driver +class splits up each test into it's own individual lines, and then runs each test synchronously in its own thread. Support +for concurrent behavior can easily be added later. + +On the client side, for the most part, each test thread just parses through each line of the test in order, synchronously and enacts its +behavior on our TestSubscriber, a special subscriber that we can use to verify that certain things have happened. `await` calls +should block the main test thread, and the test should fail if a single assert fails. + +Things get trickier with channel tests, because the client and server need to have the same behavior. In channel tests on both +sides, the driver creates a ParseChannel object, which parses through the contents of a channel tests and handles receiving +and sending data. We use the ParseMarble object to handle sending data. Here, we have one thread that continuously runs `parse()`, +and other threads that run `add()` and `request()`, which stages data to be added and requested. + + + +## Run Instructions + +You can build the project with `gradle build`. +You can run the client and server using the `run` script with `./run [options]`. The options are: + +`--server` : This is if you want to launch the server + +`--client` : This is if you want to launch the client + +`--host ` : This is for the client only, determines what host to connect to + +`--port

    ` : If launching as client, tells it to connect to port `p`, and if launching as server, tells what port to server on + +`--file ` : The path to the script file. Make sure to give the server and client the correct file formats + +`--debug` : This is if you want to look at the individual frames being sent and received by the client + +`--tests` : This allows you, when you're running the client, to specify the tests you want to run by name. Each test +should be comma separated. + +Examples: +`./run.sh --server --port 4567 --file src/test/resources/servertest.txt` should start up a server on port `4567` that +has its behavior determined by the file `servertest.txt`. + +`./run.sh --client --host localhost --port 4567 --file src/test/resources/clienttest.txt --debug --tests genericTest,badTest` should +start the client and have it connect to localhost on port `4567` and load the tests in `clienttest.txt` in debug mode, +and only run the tests named `genericTest` and `badTest`. + diff --git a/reactivesocket-tck-drivers/build.gradle b/reactivesocket-tck-drivers/build.gradle new file mode 100644 index 000000000..04b6e7657 --- /dev/null +++ b/reactivesocket-tck-drivers/build.gradle @@ -0,0 +1,28 @@ +apply plugin: 'application' +apply plugin: 'java' + +mainClassName = "io.reactivesocket.tckdrivers.main.Main" + +jar { + manifest { + attributes "Main-Class": "$mainClassName" + } + + from { + configurations.compile.collect { it.isDirectory() ? it : zipTree(it) } + } +} + +dependencies { + + compile project(':reactivesocket-core') + compile project(':reactivesocket-client') + compile project(':reactivesocket-transport-netty') + testCompile project(':reactivesocket-test') + compile 'com.fasterxml.jackson.core:jackson-core:2.8.0.rc2' + compile 'com.fasterxml.jackson.core:jackson-databind:2.8.0.rc2' + compile 'org.apache.commons:commons-lang3:3.4' + compile 'io.reactivex:rxnetty-tcp:0.5.2-rc.5' + compile 'io.reactivex.rxjava2:rxjava:2.0.2' + compile 'io.airlift:airline:0.7' +} diff --git a/reactivesocket-tck-drivers/run.sh b/reactivesocket-tck-drivers/run.sh new file mode 100755 index 000000000..62ff4fde9 --- /dev/null +++ b/reactivesocket-tck-drivers/run.sh @@ -0,0 +1,7 @@ +#!/bin/bash + +LATEST_VERSION=$(ls build/libs/reactivesocket-tck-drivers-*-SNAPSHOT.jar | sort -r | head -1) + +echo "running latest version $LATEST_VERSION" + +java -cp "$LATEST_VERSION" io.reactivesocket.tckdrivers.main.Main "$@" diff --git a/reactivesocket-tck-drivers/src/main/java/io/reactivesocket/tckdrivers/client/JavaClientDriver.java b/reactivesocket-tck-drivers/src/main/java/io/reactivesocket/tckdrivers/client/JavaClientDriver.java new file mode 100644 index 000000000..9c2d186f2 --- /dev/null +++ b/reactivesocket-tck-drivers/src/main/java/io/reactivesocket/tckdrivers/client/JavaClientDriver.java @@ -0,0 +1,620 @@ +/* + * Copyright 2016 Facebook, Inc. + *
