Creation of a buffer

- * - * It is recommended to create a new buffer using the helper methods in - * {@link Unpooled} rather than calling an individual implementation's - * constructor. - * - *

Random Access Indexing

- * - * Just like an ordinary primitive byte array, {@link ByteBuf} uses - * zero-based indexing. - * It means the index of the first byte is always {@code 0} and the index of the last byte is - * always {@link #capacity() capacity - 1}. For example, to iterate all bytes of a buffer, you - * can do the following, regardless of its internal implementation: - * - * 
- * {@link ByteBuf} buffer = ...;
- * for (int i = 0; i < buffer.capacity(); i ++) {
- *     byte b = buffer.getByte(i);
- *     System.out.println((char) b);
- * }
- *
- * - *

Sequential Access Indexing

- * - * {@link ByteBuf} provides two pointer variables to support sequential - * read and write operations - {@link #readerIndex() readerIndex} for a read - * operation and {@link #writerIndex() writerIndex} for a write operation - * respectively. The following diagram shows how a buffer is segmented into - * three areas by the two pointers: - * - * 
- *      +-------------------+------------------+------------------+
- *      | discardable bytes |  readable bytes  |  writable bytes  |
- *      |                   |     (CONTENT)    |                  |
- *      +-------------------+------------------+------------------+
- *      |                   |                  |                  |
- *      0      <=      readerIndex   <=   writerIndex    <=    capacity
- *
- * - *

Readable bytes (the actual content)

- * - * This segment is where the actual data is stored. Any operation whose name - * starts with {@code read} or {@code skip} will get or skip the data at the - * current {@link #readerIndex() readerIndex} and increase it by the number of - * read bytes. If the argument of the read operation is also a - * {@link ByteBuf} and no destination index is specified, the specified - * buffer's {@link #writerIndex() writerIndex} is increased together. - *

- * If there's not enough content left, {@link IndexOutOfBoundsException} is - * raised. The default value of newly allocated, wrapped or copied buffer's - * {@link #readerIndex() readerIndex} is {@code 0}. - * - * 

- * // Iterates the readable bytes of a buffer.
- * {@link ByteBuf} buffer = ...;
- * while (buffer.isReadable()) {
- *     System.out.println(buffer.readByte());
- * }
- *
- * - *

Writable bytes

- * - * This segment is a undefined space which needs to be filled. Any operation - * whose name ends with {@code write} will write the data at the current - * {@link #writerIndex() writerIndex} and increase it by the number of written - * bytes. If the argument of the write operation is also a {@link ByteBuf}, - * and no source index is specified, the specified buffer's - * {@link #readerIndex() readerIndex} is increased together. - *

- * If there's not enough writable bytes left, {@link IndexOutOfBoundsException} - * is raised. The default value of newly allocated buffer's - * {@link #writerIndex() writerIndex} is {@code 0}. The default value of - * wrapped or copied buffer's {@link #writerIndex() writerIndex} is the - * {@link #capacity() capacity} of the buffer. - * - * 

- * // Fills the writable bytes of a buffer with random integers.
- * {@link ByteBuf} buffer = ...;
- * while (buffer.maxWritableBytes() >= 4) {
- *     buffer.writeInt(random.nextInt());
- * }
- *
- * - *

Discardable bytes

- * - * This segment contains the bytes which were read already by a read operation. - * Initially, the size of this segment is {@code 0}, but its size increases up - * to the {@link #writerIndex() writerIndex} as read operations are executed. - * The read bytes can be discarded by calling {@link #discardReadBytes()} to - * reclaim unused area as depicted by the following diagram: - * - * 
- *  BEFORE discardReadBytes()
- *
- *      +-------------------+------------------+------------------+
- *      | discardable bytes |  readable bytes  |  writable bytes  |
- *      +-------------------+------------------+------------------+
- *      |                   |                  |                  |
- *      0      <=      readerIndex   <=   writerIndex    <=    capacity
- *
- *
- *  AFTER discardReadBytes()
- *
- *      +------------------+--------------------------------------+
- *      |  readable bytes  |    writable bytes (got more space)   |
- *      +------------------+--------------------------------------+
- *      |                  |                                      |
- * readerIndex (0) <= writerIndex (decreased)        <=        capacity
- *
- * - * Please note that there is no guarantee about the content of writable bytes - * after calling {@link #discardReadBytes()}. The writable bytes will not be - * moved in most cases and could even be filled with completely different data - * depending on the underlying buffer implementation. - * - *

Clearing the buffer indexes

- * - * You can set both {@link #readerIndex() readerIndex} and - * {@link #writerIndex() writerIndex} to {@code 0} by calling {@link #clear()}. - * It does not clear the buffer content (e.g. filling with {@code 0}) but just - * clears the two pointers. Please also note that the semantic of this - * operation is different from {@link ByteBuffer#clear()}. - * - * 
- *  BEFORE clear()
- *
- *      +-------------------+------------------+------------------+
- *      | discardable bytes |  readable bytes  |  writable bytes  |
- *      +-------------------+------------------+------------------+
- *      |                   |                  |                  |
- *      0      <=      readerIndex   <=   writerIndex    <=    capacity
- *
- *
- *  AFTER clear()
- *
- *      +---------------------------------------------------------+
- *      |             writable bytes (got more space)             |
- *      +---------------------------------------------------------+
- *      |                                                         |
- *      0 = readerIndex = writerIndex            <=            capacity
- *
- * - *

Search operations

- * - * For simple single-byte searches, use {@link #indexOf(int, int, byte)} and {@link #bytesBefore(int, int, byte)}. - * {@link #bytesBefore(byte)} is especially useful when you deal with a {@code NUL}-terminated string. - * For complicated searches, use {@link #forEachByte(int, int, ByteBufProcessor)} with a {@link ByteBufProcessor} - * implementation. - * - *

Mark and reset

- * - * There are two marker indexes in every buffer. One is for storing - * {@link #readerIndex() readerIndex} and the other is for storing - * {@link #writerIndex() writerIndex}. You can always reposition one of the - * two indexes by calling a reset method. It works in a similar fashion to - * the mark and reset methods in {@link InputStream} except that there's no - * {@code readlimit}. - * - *

Derived buffers

- * - * You can create a view of an existing buffer by calling either - * {@link #duplicate()}, {@link #slice()} or {@link #slice(int, int)}. - * A derived buffer will have an independent {@link #readerIndex() readerIndex}, - * {@link #writerIndex() writerIndex} and marker indexes, while it shares - * other internal data representation, just like a NIO buffer does. - *

- * In case a completely fresh copy of an existing buffer is required, please - * call {@link #copy()} method instead. - *

- * Also be aware that obtaining derived buffers will NOT call {@link #retain()} and so the - * reference count will NOT be increased. - * - *

Conversion to existing JDK types

- * - *

Byte array

- * - * If a {@link ByteBuf} is backed by a byte array (i.e. {@code byte[]}), - * you can access it directly via the {@link #array()} method. To determine - * if a buffer is backed by a byte array, {@link #hasArray()} should be used. - * - *

NIO Buffers

- * - * If a {@link ByteBuf} can be converted into an NIO {@link ByteBuffer} which shares its - * content (i.e. view buffer), you can get it via the {@link #nioBuffer()} method. To determine - * if a buffer can be converted into an NIO buffer, use {@link #nioBufferCount()}. - * - *

Strings

- * - * Various {@link #toString(Charset)} methods convert a {@link ByteBuf} - * into a {@link String}. Please note that {@link #toString()} is not a - * conversion method. - * - *

Allocating a new buffer

Creating a wrapped buffer

- * - * Wrapped buffer is a buffer which is a view of one or more existing - * byte arrays and byte buffers. Any changes in the content of the original - * array or buffer will be visible in the wrapped buffer.

Creating a copied buffer

- * - * Copied buffer is a deep copy of one or more existing byte arrays, byte - * buffers or a string. Unlike a wrapped buffer, there's no shared data - * between the original data and the copied buffer. Various copy methods are - * provided and their name is all {@code copiedBuffer()}.

This approach has significant advantage over - * using {@link java.nio.ByteBuffer}. Netty's new buffer type, - * {@link com.ai.cloud.io.netty.buffer.ByteBuf}, has been designed from ground - * up to address the problems of {@link java.nio.ByteBuffer} and to meet the - * daily needs of network application developers. To list a few cool features: - *
    - *
  • You can define your buffer type if necessary.
    • - *
  • Transparent zero copy is achieved by built-in composite buffer type.
    • - *
  • A dynamic buffer type is provided out-of-the-box, whose capacity is - * expanded on demand, just like {@link java.lang.StringBuffer}.
    • - *
  • There's no need to call the {@code flip()} method anymore.
    • - *
  • It is often faster than {@link java.nio.ByteBuffer}.
    • - *
- * - *

Extensibility

- * - * {@link com.ai.cloud.io.netty.buffer.ByteBuf} has rich set of operations - * optimized for rapid protocol implementation. For example, - * {@link com.ai.cloud.io.netty.buffer.ByteBuf} provides various operations - * for accessing unsigned values and strings and searching for certain byte - * sequence in a buffer. You can also extend or wrap existing buffer type - * to add convenient accessors. The custom buffer type still implements - * {@link com.ai.cloud.io.netty.buffer.ByteBuf} interface rather than - * introducing an incompatible type. - * - *

Transparent Zero Copy

- * - * To lift up the performance of a network application to the extreme, you need - * to reduce the number of memory copy operation. You might have a set of - * buffers that could be sliced and combined to compose a whole message. Netty - * provides a composite buffer which allows you to create a new buffer from the - * arbitrary number of existing buffers with no memory copy. For example, a - * message could be composed of two parts; header and body. In a modularized - * application, the two parts could be produced by different modules and - * assembled later when the message is sent out. - * 
- * +--------+----------+
- * | header |   body   |
- * +--------+----------+
- *
- * If {@link java.nio.ByteBuffer} were used, you would have to create a new big - * buffer and copy the two parts into the new buffer. Alternatively, you can - * perform a gathering write operation in NIO, but it restricts you to represent - * the composite of buffers as an array of {@link java.nio.ByteBuffer}s rather - * than a single buffer, breaking the abstraction and introducing complicated - * state management. Moreover, it's of no use if you are not going to read or - * write from an NIO channel. - * 
- * // The composite type is incompatible with the component type.
- * ByteBuffer[] message = new ByteBuffer[] { header, body };
- *
- * By contrast, {@link com.ai.cloud.io.netty.buffer.ByteBuf} does not have such - * caveats because it is fully extensible and has a built-in composite buffer - * type. - * 
- * // The composite type is compatible with the component type.
- * {@link ByteBuf} message = {@link Unpooled}.wrappedBuffer(header, body);
- *
- * // Therefore, you can even create a composite by mixing a composite and an
- * // ordinary buffer.
- * {@link ByteBuf} messageWithFooter = {@link Unpooled}.wrappedBuffer(message, footer);
- *
- * // Because the composite is still a {@link ByteBuf}, you can access its content
- * // easily, and the accessor method will behave just like it's a single buffer
- * // even if the region you want to access spans over multiple components.  The
- * // unsigned integer being read here is located across body and footer.
- * messageWithFooter.getUnsignedInt(
- *     messageWithFooter.readableBytes() - footer.readableBytes() - 1);
- *
- * - *

Automatic Capacity Extension

- * - * Many protocols define variable length messages, which means there's no way to - * determine the length of a message until you construct the message or it is - * difficult and inconvenient to calculate the length precisely. It is just - * like when you build a {@link java.lang.String}. You often estimate the length - * of the resulting string and let {@link java.lang.StringBuffer} expand itself - * on demand. - * 
- * // A new dynamic buffer is created.  Internally, the actual buffer is created
- * // lazily to avoid potentially wasted memory space.
- * {@link ByteBuf} b = {@link Unpooled}.buffer(4);
- *
- * // When the first write attempt is made, the internal buffer is created with
- * // the specified initial capacity (4).
- * b.writeByte('1');
- *
- * b.writeByte('2');
- * b.writeByte('3');
- * b.writeByte('4');
- *
- * // When the number of written bytes exceeds the initial capacity (4), the
- * // internal buffer is reallocated automatically with a larger capacity.
- * b.writeByte('5');
- *
- * - *

Better Performance

- * - * Most frequently used buffer implementation of - * {@link com.ai.cloud.io.netty.buffer.ByteBuf} is a very thin wrapper of a - * byte array (i.e. {@code byte[]}). Unlike {@link java.nio.ByteBuffer}, it has - * no complicated boundary check and index compensation, and therefore it is - * easier for a JVM to optimize the buffer access. More complicated buffer - * implementation is used only for sliced or composite buffers, and it performs - * as well as {@link java.nio.ByteBuffer}. - */ -package com.ai.cloud.io.netty.buffer; diff --git a/skywalking-api/src/main/java/com/ai/cloud/io/netty/channel/AbstractChannel.java b/skywalking-api/src/main/java/com/ai/cloud/io/netty/channel/AbstractChannel.java deleted file mode 100755 index 8bbb36fbf8..0000000000 --- a/skywalking-api/src/main/java/com/ai/cloud/io/netty/channel/AbstractChannel.java +++ /dev/null @@ -1,970 +0,0 @@ -/* - * Copyright 2012 The Netty Project - * - * The Netty Project licenses this file to you under the Apache License, - * version 2.0 (the "License"); you may not use this file except in compliance - * with the License.

For example, you could - * write a new {@link Channel} implementation that creates the sub-channels that - * share one socket connection, as BEEP and - * SSH do. - * - *

Downcast to access transport-specific operations

- *

- * Some transports exposes additional operations that is specific to the - * transport. Down-cast the {@link Channel} to sub-type to invoke such - * operations. For example, with the old I/O datagram transport, multicast - * join / leave operations are provided by {@link DatagramChannel}. - * - *

- *

- * - * Various methods are provided to let you check if the I/O operation has been - * completed, wait for the completion, and retrieve the result of the I/O - * operation. It also allows you to add {@link ChannelFutureListener}s so you - * can get notified when the I/O operation is completed. - * - *

Prefer {@link #addListener(GenericFutureListener)} to {@link #await()}

- * - * It is recommended to prefer {@link #addListener(GenericFutureListener)} to - * {@link #await()} wherever possible to get notified when an I/O operation is - * done and to do any follow-up tasks. - *

- * {@link #addListener(GenericFutureListener)} is non-blocking. It simply adds - * the specified {@link ChannelFutureListener} to the {@link ChannelFuture}, and - * I/O thread will notify the listeners when the I/O operation associated with - * the future is done. {@link ChannelFutureListener} yields the best - * performance and resource utilization because it does not block at all, but - * it could be tricky to implement a sequential logic if you are not used to - * event-driven programming. - *

- * By contrast, {@link #await()} is a blocking operation. Once called, the - * caller thread blocks until the operation is done. It is easier to implement - * a sequential logic with {@link #await()}, but the caller thread blocks - * unnecessarily until the I/O operation is done and there's relatively - * expensive cost of inter-thread notification. Moreover, there's a chance of - * dead lock in a particular circumstance, which is described below. - * - *

Do not call {@link #await()} inside {@link ChannelHandler}

- *

- * The event handler methods in {@link ChannelHandler} is usually called by - * an I/O thread. If {@link #await()} is called by an event handler - * method, which is called by the I/O thread, the I/O operation it is waiting - * for might never be complete because {@link #await()} can block the I/O - * operation it is waiting for, which is a dead lock. - * 

- * // BAD - NEVER DO THIS
- * {@code @Override}
- * public void channelRead({@link ChannelHandlerContext} ctx, GoodByeMessage msg) {
- *     {@link ChannelFuture} future = ctx.channel().close();
- *     future.awaitUninterruptibly();
- *     // Perform post-closure operation
- *     // ...
- * }
- *
- * // GOOD
- * {@code @Override}
- * public void channelRead({@link ChannelHandlerContext} ctx,  GoodByeMessage msg) {
- *     {@link ChannelFuture} future = ctx.channel().close();
- *     future.addListener(new {@link ChannelFutureListener}() {
- *         public void operationComplete({@link ChannelFuture} future) {
- *             // Perform post-closure operation
- *             // ...
- *         }
- *     });
- * }
- *
- *

- * In spite of the disadvantages mentioned above, there are certainly the cases - * where it is more convenient to call {@link #await()}. In such a case, please - * make sure you do not call {@link #await()} in an I/O thread. Otherwise, - * {@link BlockingOperationException} will be raised to prevent a dead lock. - * - *

Do not confuse I/O timeout and await timeout

- * - * The timeout value you specify with {@link #await(long)}, - * {@link #await(long, TimeUnit)}, {@link #awaitUninterruptibly(long)}, or - * {@link #awaitUninterruptibly(long, TimeUnit)} are not related with I/O - * timeout at all. If an I/O operation times out, the future will be marked as - * 'completed with failure,' as depicted in the diagram above. For example, - * connect timeout should be configured via a transport-specific option: - * 
- * // BAD - NEVER DO THIS
- * {@link Bootstrap} b = ...;
- * {@link ChannelFuture} f = b.connect(...);
- * f.awaitUninterruptibly(10, TimeUnit.SECONDS);
- * if (f.isCancelled()) {
- *     // Connection attempt cancelled by user
- * } else if (!f.isSuccess()) {
- *     // You might get a NullPointerException here because the future
- *     // might not be completed yet.
- *     f.cause().printStackTrace();
- * } else {
- *     // Connection established successfully
- * }
- *
- * // GOOD
- * {@link Bootstrap} b = ...;
- * // Configure the connect timeout option.
- * b.option({@link ChannelOption}.CONNECT_TIMEOUT_MILLIS, 10000);
- * {@link ChannelFuture} f = b.connect(...);
- * f.awaitUninterruptibly();
- *
- * // Now we are sure the future is completed.
- * assert f.isDone();
- *
- * if (f.isCancelled()) {
- *     // Connection attempt cancelled by user
- * } else if (!f.isSuccess()) {
- *     f.cause().printStackTrace();
- * } else {
- *     // Connection established successfully
- * }

Sub-types

- *

- * {@link ChannelHandler} itself does not provide many methods. To handle a - * a {@link ChannelInboundInvoker} or {@link ChannelOutboundInvoker} operation - * you need to implement its sub-interfaces. There are many different sub-interfaces - * which handles inbound and outbound operations. - * - * But the most useful for developers may be: - *

    - *
  • {@link ChannelInboundHandlerAdapter} handles and intercepts inbound operations
    • - *
  • {@link ChannelOutboundHandlerAdapter} handles and intercepts outbound operations
    • - *
- * - * You will also find more detailed explanation from the documentation of - * each sub-interface on how an event is interpreted when it goes upstream and - * downstream respectively. - * - *

The context object

- *

- * A {@link ChannelHandler} is provided with a {@link ChannelHandlerContext} - * object. A {@link ChannelHandler} is supposed to interact with the - * {@link ChannelPipeline} it belongs to via a context object. Using the - * context object, the {@link ChannelHandler} can pass events upstream or - * downstream, modify the pipeline dynamically, or store the information - * (using {@link AttributeKey}s) which is specific to the handler. - * - *

State management

- * - * A {@link ChannelHandler} often needs to store some stateful information. - * The simplest and recommended approach is to use member variables: - * 
- * public interface Message {
- *     // your methods here
- * }
- *
- * public class DataServerHandler extends {@link SimpleChannelInboundHandler}<Message> {
- *
- *     private boolean loggedIn;
- *
- *     {@code @Override}
- *     public void channelRead0({@link ChannelHandlerContext} ctx, Message message) {
- *         {@link Channel} ch = e.getChannel();
- *         if (message instanceof LoginMessage) {
- *             authenticate((LoginMessage) message);
- *             loggedIn = true;
- *         } else (message instanceof GetDataMessage) {
- *             if (loggedIn) {
- *                 ch.write(fetchSecret((GetDataMessage) message));
- *             } else {
- *                 fail();
- *             }
- *         }
- *     }
- *     ...
- * }
- *
- * Because the handler instance has a state variable which is dedicated to - * one connection, you have to create a new handler instance for each new - * channel to avoid a race condition where a unauthenticated client can get - * the confidential information: - * 
- * // Create a new handler instance per channel.
- * // See {@link ChannelInitializer#initChannel(Channel)}.
- * public class DataServerInitializer extends {@link ChannelInitializer}<{@link Channel}> {
- *     {@code @Override}
- *     public void initChannel({@link Channel} channel) {
- *         channel.pipeline().addLast("handler", new DataServerHandler());
- *     }
- * }
- *
- *
- * - *

Using {@link AttributeKey}

- * - * Although it's recommended to use member variables to store the state of a - * handler, for some reason you might not want to create many handler instances. - * In such a case, you can use {@link AttributeKey}s which is provided by - * {@link ChannelHandlerContext}: - * 
- * public interface Message {
- *     // your methods here
- * }
- *
- * {@code @Sharable}
- * public class DataServerHandler extends {@link SimpleChannelInboundHandler}<Message> {
- *     private final {@link AttributeKey}<{@link Boolean}> auth =
- *           {@link AttributeKey#valueOf(String) AttributeKey.valueOf("auth")};
- *
- *     {@code @Override}
- *     public void channelRead({@link ChannelHandlerContext} ctx, Message message) {
- *         {@link Attribute}<{@link Boolean}> attr = ctx.attr(auth);
- *         {@link Channel} ch = ctx.channel();
- *         if (message instanceof LoginMessage) {
- *             authenticate((LoginMessage) o);
- *             attr.set(true);
- *         } else (message instanceof GetDataMessage) {
- *             if (Boolean.TRUE.equals(attr.get())) {
- *                 ch.write(fetchSecret((GetDataMessage) o));
- *             } else {
- *                 fail();
- *             }
- *         }
- *     }
- *     ...
- * }
- *
- * Now that the state of the handler isattached to the {@link ChannelHandlerContext}, you can add the - * same handler instance to different pipelines: - * 
- * public class DataServerInitializer extends {@link ChannelInitializer}<{@link Channel}> {
- *
- *     private static final DataServerHandler SHARED = new DataServerHandler();
- *
- *     {@code @Override}
- *     public void initChannel({@link Channel} channel) {
- *         channel.pipeline().addLast("handler", SHARED);
- *     }
- * }
- *
- * - * - *

The {@code @Sharable} annotation

- *

- * In the example above which used an {@link AttributeKey}, - * you might have noticed the {@code @Sharable} annotation. - *

- * If a {@link ChannelHandler} is annotated with the {@code @Sharable} - * annotation, it means you can create an instance of the handler just once and - * add it to one or more {@link ChannelPipeline}s multiple times without - * a race condition. - *

- * If this annotation is not specified, you have to create a new handler - * instance every time you add it to a pipeline because it has unshared state - * such as member variables. - *

- * This annotation is provided for documentation purpose, just like - * the JCIP annotations. - * - *

Notify

- * - * You can notify the closest handler in the - * same {@link ChannelPipeline} by calling one of the various methods provided here. - * Please refer to {@link ChannelPipeline} to understand how an event flows. - * - *

Modifying a pipeline

- * - * You can get the {@link ChannelPipeline} your handler belongs to by calling - * {@link #pipeline()}. A non-trivial application could insert, remove, or - * replace handlers in the pipeline dynamically at runtime. - * - *

Retrieving for later use

- * - * You can keep the {@link ChannelHandlerContext} for later use, such as - * triggering an event outside the handler methods, even from a different thread. - * 
- * public class MyHandler extends {@link ChannelDuplexHandler} {
- *
- *     private {@link ChannelHandlerContext} ctx;

Storing stateful information

- * - * {@link #attr(AttributeKey)} allow you to - * store and access stateful information that is related with a handler and its - * context. Please refer to {@link ChannelHandler} to learn various recommended - * ways to manage stateful information. - * - *

A handler can have more than one context

- * - * Please note that a {@link ChannelHandler} instance can be added to more than - * one {@link ChannelPipeline}. It means a single {@link ChannelHandler} - * instance can have more than one {@link ChannelHandlerContext} and therefore - * the single instance can be invoked with different - * {@link ChannelHandlerContext}s if it is added to one or more - * {@link ChannelPipeline}s more than once. - *

- * For example, the following handler will have as many independent {@link AttributeKey}s - * as how many times it is added to pipelines, regardless if it is added to the - * same pipeline multiple times or added to different pipelines multiple times: - * 

- * public class FactorialHandler extends {@link ChannelInboundHandlerAdapter}<{@link Integer}> {
- *
- *   private final {@link AttributeKey}<{@link Integer}> counter =
- *           new {@link AttributeKey}<{@link Integer}>("counter");
- *
- *   // This handler will receive a sequence of increasing integers starting
- *   // from 1.
- *   {@code @Override}
- *   public void channelRead({@link ChannelHandlerContext} ctx, {@link Integer} integer) {
- *     {@link Attribute}<{@link Integer}> attr = ctx.getAttr(counter);
- *     Integer a = ctx.getAttr(counter).get();
- *
- *     if (a == null) {
- *       a = 1;
- *     }
- *
- *     attr.set(a * integer));
- *   }
- * }
- *
- * // Different context objects are given to "f1", "f2", "f3", and "f4" even if
- * // they refer to the same handler instance.  Because the FactorialHandler
- * // stores its state in a context object (as an (using an {@link AttributeKey}), the factorial is
- * // calculated correctly 4 times once the two pipelines (p1 and p2) are active.
- * FactorialHandler fh = new FactorialHandler();
- *
- * {@link ChannelPipeline} p1 = {@link Channels}.pipeline();
- * p1.addLast("f1", fh);
- * p1.addLast("f2", fh);
- *
- * {@link ChannelPipeline} p2 = {@link Channels}.pipeline();
- * p2.addLast("f3", fh);
- * p2.addLast("f4", fh);

The inbound data is often read from a remote peer via the actual input operation such as - * {@link SocketChannel#read(ByteBuffer)}. If an inbound event goes beyond the top inbound handler, it is discarded - * silently, or logged if it needs your attention. - *

- * An outbound event is handled by the outbound handler in the top-down direction as shown on the right side of the - * diagram. An outbound handler usually generates or transforms the outbound traffic such as write requests. - * If an outbound event goes beyond the bottom outbound handler, it is handled by an I/O thread associated with the - * {@link Channel}. The I/O thread often performs the actual output operation such as - * {@link SocketChannel#write(ByteBuffer)}. - *

- * For example, let us assume that we created the following pipeline: - * 

- * {@link ChannelPipeline} p = ...;
- * p.addLast("1", new InboundHandlerA());
- * p.addLast("2", new InboundHandlerB());
- * p.addLast("3", new OutboundHandlerA());
- * p.addLast("4", new OutboundHandlerB());
- * p.addLast("5", new InboundOutboundHandlerX());
- *
- * In the example above, the class whose name starts with {@code Inbound} means it is an inbound handler. - * The class whose name starts with {@code Outbound} means it is a outbound handler. - *

- * In the given example configuration, the handler evaluation order is 1, 2, 3, 4, 5 when an event goes inbound. - * When an event goes outbound, the order is 5, 4, 3, 2, 1. On top of this principle, {@link ChannelPipeline} skips - * the evaluation of certain handlers to shorten the stack depth: - *

    - *
  • 3 and 4 don't implement {@link ChannelInboundHandler}, and therefore the actual evaluation order of an inbound - * event will be: 1, 2, and 5.
    • - *
  • 1 and 2 don't implement {@link ChannelOutboundHandler}, and therefore the actual evaluation order of a - * outbound event will be: 5, 4, and 3.
    • - *
  • If 5 implements both {@link ChannelInboundHandler} and {@link ChannelOutboundHandler}, the evaluation order of - * an inbound and a outbound event could be 125 and 543 respectively.
    • - *
- * - *

Forwarding an event to the next handler

- * - * As you might noticed in the diagram shows, a handler has to invoke the event propagation methods in - * {@link ChannelHandlerContext} to forward an event to its next handler. Those methods include: - *
    - *
  • Inbound event propagation methods: - *
      - *
    • {@link ChannelHandlerContext#fireChannelRegistered()}
      • - *
    • {@link ChannelHandlerContext#fireChannelActive()}
      • - *
    • {@link ChannelHandlerContext#fireChannelRead(Object)}
      • - *
    • {@link ChannelHandlerContext#fireChannelReadComplete()}
      • - *
    • {@link ChannelHandlerContext#fireExceptionCaught(Throwable)}
      • - *
    • {@link ChannelHandlerContext#fireUserEventTriggered(Object)}
      • - *
    • {@link ChannelHandlerContext#fireChannelWritabilityChanged()}
      • - *
    • {@link ChannelHandlerContext#fireChannelInactive()}
      • - *
    • {@link ChannelHandlerContext#fireChannelUnregistered()}
      • - *
    - *
    • - *
  • Outbound event propagation methods: - *
      - *
    • {@link ChannelHandlerContext#bind(SocketAddress, ChannelPromise)}
      • - *
    • {@link ChannelHandlerContext#connect(SocketAddress, SocketAddress, ChannelPromise)}
      • - *
    • {@link ChannelHandlerContext#write(Object, ChannelPromise)}
      • - *
    • {@link ChannelHandlerContext#flush()}
      • - *
    • {@link ChannelHandlerContext#read()}
      • - *
    • {@link ChannelHandlerContext#disconnect(ChannelPromise)}
      • - *
    • {@link ChannelHandlerContext#close(ChannelPromise)}
      • - *
    • {@link ChannelHandlerContext#deregister(ChannelPromise)}
      • - *
    - *
    • - *
- * - * and the following example shows how the event propagation is usually done: - * - * 
- * public class MyInboundHandler extends {@link ChannelInboundHandlerAdapter} {
- *     {@code @Override}
- *     public void channelActive({@link ChannelHandlerContext} ctx) {
- *         System.out.println("Connected!");
- *         ctx.fireChannelActive();
- *     }
- * }
- *
- * public clas MyOutboundHandler extends {@link ChannelOutboundHandlerAdapter} {
- *     {@code @Override}
- *     public void close({@link ChannelHandlerContext} ctx, {@link ChannelPromise} promise) {
- *         System.out.println("Closing ..");
- *         ctx.close(promise);
- *     }
- * }
- *
- * - *

Building a pipeline

- *

- * A user is supposed to have one or more {@link ChannelHandler}s in a pipeline to receive I/O events (e.g. read) and - * to request I/O operations (e.g. write and close). For example, a typical server will have the following handlers - * in each channel's pipeline, but your mileage may vary depending on the complexity and characteristics of the - * protocol and business logic: - * - *

    - *
  1. Protocol Decoder - translates binary data (e.g. {@link ByteBuf}) into a Java object.
    2. - *
  2. Protocol Encoder - translates a Java object into binary data.
    3. - *
  3. Business Logic Handler - performs the actual business logic (e.g. database access).
    4. - *
- * - * and it could be represented as shown in the following example: - * - * 
- * static final {@link EventExecutorGroup} group = new {@link DefaultEventExecutorGroup}(16);
- * ...
- *
- * {@link ChannelPipeline} pipeline = ch.pipeline();
- *
- * pipeline.addLast("decoder", new MyProtocolDecoder());
- * pipeline.addLast("encoder", new MyProtocolEncoder());
- *
- * // Tell the pipeline to run MyBusinessLogicHandler's event handler methods
- * // in a different thread than an I/O thread so that the I/O thread is not blocked by
- * // a time-consuming task.
- * // If your business logic is fully asynchronous or finished very quickly, you don't
- * // need to specify a group.
- * pipeline.addLast(group, "handler", new MyBusinessLogicHandler());
- *
- * - *

Thread safety

- *

- * A {@link ChannelHandler} can be added or removed at any time because a {@link ChannelPipeline} is thread safe. - * For example, you can insert an encryption handler when sensitive information is about to be exchanged, and remove it - * after the exchange. - */ -public interface ChannelPipeline - extends Iterable> { - - /** - * Inserts a {@link ChannelHandler} at the first position of this pipeline. - * - * @param name the name of the handler to insert first - * @param handler the handler to insert first - * - * @throws IllegalArgumentException - * if there's an entry with the same name already in the pipeline - * @throws NullPointerException - * if the specified name or handler is {@code null} - */ - ChannelPipeline addFirst(String name, ChannelHandler handler);

- * All I/O operations in {@link ChannelGroup} are asynchronous. It means any - * I/O calls will return immediately with no guarantee that the requested I/O - * operations have been completed at the end of the call. Instead, you will be - * returned with a {@link ChannelGroupFuture} instance which tells you when the - * requested I/O operations have succeeded, failed, or cancelled. - *

- * Various methods are provided to let you check if the I/O operations has been - * completed, wait for the completion, and retrieve the result of the I/O - * operation. It also allows you to add more than one - * {@link ChannelGroupFutureListener} so you can get notified when the I/O - * operation have been completed. - * - *

Prefer {@link #addListener(GenericFutureListener)} to {@link #await()}

- * - * It is recommended to prefer {@link #addListener(GenericFutureListener)} to - * {@link #await()} wherever possible to get notified when I/O operations are - * done and to do any follow-up tasks. - *

- * {@link #addListener(GenericFutureListener)} is non-blocking. It simply - * adds the specified {@link ChannelGroupFutureListener} to the - * {@link ChannelGroupFuture}, and I/O thread will notify the listeners when - * the I/O operations associated with the future is done. - * {@link ChannelGroupFutureListener} yields the best performance and resource - * utilization because it does not block at all, but it could be tricky to - * implement a sequential logic if you are not used to event-driven programming. - *

- * By contrast, {@link #await()} is a blocking operation. Once called, the - * caller thread blocks until all I/O operations are done. It is easier to - * implement a sequential logic with {@link #await()}, but the caller thread - * blocks unnecessarily until all I/O operations are done and there's relatively - * expensive cost of inter-thread notification. Moreover, there's a chance of - * dead lock in a particular circumstance, which is described below. - * - *

Do not call {@link #await()} inside {@link ChannelHandler}

- *

- * The event handler methods in {@link ChannelHandler} is often called by - * an I/O thread. If {@link #await()} is called by an event handler - * method, which is called by the I/O thread, the I/O operation it is waiting - * for might never be complete because {@link #await()} can block the I/O - * operation it is waiting for, which is a dead lock. - * 

- * // BAD - NEVER DO THIS
- * {@code @Override}
- * public void messageReceived({@link ChannelHandlerContext} ctx, ShutdownMessage msg) {
- *     {@link ChannelGroup} allChannels = MyServer.getAllChannels();
- *     {@link ChannelGroupFuture} future = allChannels.close();
- *     future.awaitUninterruptibly();
- *     // Perform post-shutdown operation
- *     // ...
- *
- * }
- *
- * // GOOD
- * {@code @Override}
- * public void messageReceived(ChannelHandlerContext ctx, ShutdownMessage msg) {
- *     {@link ChannelGroup} allChannels = MyServer.getAllChannels();
- *     {@link ChannelGroupFuture} future = allChannels.close();
- *     future.addListener(new {@link ChannelGroupFutureListener}() {
- *         public void operationComplete({@link ChannelGroupFuture} future) {
- *             // Perform post-closure operation
- *             // ...
- *         }
- *     });
- * }
- *
- *

- * In spite of the disadvantages mentioned above, there are certainly the cases - * where it is more convenient to call {@link #await()}. In such a case, please - * make sure you do not call {@link #await()} in an I/O thread.

Frame detection

- *

- * Generally frame detection should be handled earlier in the pipeline by adding a - * {@link DelimiterBasedFrameDecoder}, {@link FixedLengthFrameDecoder}, {@link LengthFieldBasedFrameDecoder}, - * or {@link LineBasedFrameDecoder}. - *

- * If a custom frame decoder is required, then one needs to be careful when implementing - * one with {@link ByteToMessageDecoder}. Ensure there are enough bytes in the buffer for a - * complete frame by checking {@link ByteBuf#readableBytes()}. If there are not enough bytes - * for a complete frame, return without modifying the reader index to allow more bytes to arrive. - *

- * To check for complete frames without modifying the reader index, use methods like {@link ByteBuf#getInt(int)}. - * One MUST use the reader index when using methods like {@link ByteBuf#getInt(int)}. - * For example calling in.getInt(0) is assuming the frame starts at the beginning of the buffer, which - * is not always the case. Use in.getInt(in.readerIndex()) instead. - *

Pitfalls

- *

- * Be aware that sub-classes of {@link ByteToMessageDecoder} MUST NOT - * annotated with {@link @Sharable}. - *

- * Some methods such as {@link ByteBuf#readBytes(int)} will cause a memory leak if the returned buffer - * is not released or added to the out {@link List}.

2 bytes length field at offset 0, strip header

- * - * Because we can get the length of the content by calling - * {@link ByteBuf#readableBytes()}, you might want to strip the length - * field by specifying initialBytesToStrip. In this example, we - * specified 2, that is same with the length of the length field, to - * strip the first two bytes. - *

2 bytes length field at offset 0, do not strip header, the length field - * represents the length of the whole message

- * - * In most cases, the length field represents the length of the message body - * only, as shown in the previous examples. However, in some protocols, the - * length field represents the length of the whole message, including the - * message header. In such a case, we specify a non-zero - * lengthAdjustment. Because the length value in this example message - * is always greater than the body length by 2, we specify -2 - * as lengthAdjustment for compensation. - *

3 bytes length field at the end of 5 bytes header, do not strip header

- * - * The following message is a simple variation of the first example. An extra - * header value is prepended to the message. lengthAdjustment is zero - * again because the decoder always takes the length of the prepended data into - * account during frame length calculation. - *

3 bytes length field at the beginning of 5 bytes header, do not strip header

- * - * This is an advanced example that shows the case where there is an extra - * header between the length field and the message body. You have to specify a - * positive lengthAdjustment so that the decoder counts the extra - * header into the frame length calculation. - *

- * - * This is a combination of all the examples above. There are the prepended - * header before the length field and the extra header after the length field. - * The prepended header affects the lengthFieldOffset and the extra - * header affects the lengthAdjustment.

- * - * Let's give another twist to the previous example.

- * The biggest difference between {@link ReplayingDecoder} and - * {@link ByteToMessageDecoder} is that {@link ReplayingDecoder} allows you to - * implement the {@code decode()} and {@code decodeLast()} methods just like - * all required bytes were received already, rather than checking the - * availability of the required bytes. For example, the following - * {@link ByteToMessageDecoder} implementation: - * 

- * public class IntegerHeaderFrameDecoder extends {@link ByteToMessageDecoder} {
- *
- *   {@code @Override}
- *   protected void decode({@link ChannelHandlerContext} ctx,
- *                           {@link ByteBuf} buf, List<Object> out) throws Exception {
- *
- *     if (buf.readableBytes() < 4) {
- *        return;
- *     }
- *
- *     buf.markReaderIndex();
- *     int length = buf.readInt();
- *
- *     if (buf.readableBytes() < length) {
- *        buf.resetReaderIndex();
- *        return;
- *     }
- *
- *     out.add(buf.readBytes(length));
- *   }
- * }
- *
- * is simplified like the following with {@link ReplayingDecoder}: - * 
- * public class IntegerHeaderFrameDecoder
- *      extends {@link ReplayingDecoder}<{@link Void}> {
- *
- *   protected void decode({@link ChannelHandlerContext} ctx,
- *                           {@link ByteBuf} buf) throws Exception {
- *
- *     out.add(buf.readBytes(buf.readInt()));
- *   }
- * }
- *
- * - *

How does this work?

- *

- * {@link ReplayingDecoder} passes a specialized {@link ByteBuf} - * implementation which throws an {@link Error} of certain type when there's not - * enough data in the buffer. In the {@code IntegerHeaderFrameDecoder} above, - * you just assumed that there will be 4 or more bytes in the buffer when - * you call {@code buf.readInt()}. If there's really 4 bytes in the buffer, - * it will return the integer header as you expected. Otherwise, the - * {@link Error} will be raised and the control will be returned to - * {@link ReplayingDecoder}. If {@link ReplayingDecoder} catches the - * {@link Error}, then it will rewind the {@code readerIndex} of the buffer - * back to the 'initial' position (i.e. the beginning of the buffer) and call - * the {@code decode(..)} method again when more data is received into the - * buffer. - *

- * Please note that {@link ReplayingDecoder} always throws the same cached - * {@link Error} instance to avoid the overhead of creating a new {@link Error} - * and filling its stack trace for every throw. - * - *

Limitations

- *

- * At the cost of the simplicity, {@link ReplayingDecoder} enforces you a few - * limitations: - *

    - *
  • Some buffer operations are prohibited.
    • - *
  • Performance can be worse if the network is slow and the message - * format is complicated unlike the example above. In this case, your - * decoder might have to decode the same part of the message over and over - * again.
    • - *
  • You must keep in mind that {@code decode(..)} method can be called many - * times to decode a single message. For example, the following code will - * not work: - * 
     public class MyDecoder extends {@link ReplayingDecoder}<{@link Void}> {
- *
- *   private final Queue<Integer> values = new LinkedList<Integer>();
- *
- *   {@code @Override}
- *   public void decode(.., {@link ByteBuf} buf, List<Object> out) throws Exception {
- *
- *     // A message contains 2 integers.
- *     values.offer(buf.readInt());
- *     values.offer(buf.readInt());
- *
- *     // This assertion will fail intermittently since values.offer()
- *     // can be called more than two times!
- *     assert values.size() == 2;
- *     out.add(values.poll() + values.poll());
- *   }
- * }
    - * The correct implementation looks like the following, and you can also - * utilize the 'checkpoint' feature which is explained in detail in the - * next section. - * 
     public class MyDecoder extends {@link ReplayingDecoder}<{@link Void}> {
- *
- *   private final Queue<Integer> values = new LinkedList<Integer>();
- *
- *   {@code @Override}
- *   public void decode(.., {@link ByteBuf} buf, List<Object> out) throws Exception {
- *
- *     // Revert the state of the variable that might have been changed
- *     // since the last partial decode.
- *     values.clear();
- *
- *     // A message contains 2 integers.
- *     values.offer(buf.readInt());
- *     values.offer(buf.readInt());
- *
- *     // Now we know this assertion will never fail.
- *     assert values.size() == 2;
- *     out.add(values.poll() + values.poll());
- *   }
- * }
    - *
    • - *
- * - *

Improving the performance

- *

- * Fortunately, the performance of a complex decoder implementation can be - * improved significantly with the {@code checkpoint()} method. The - * {@code checkpoint()} method updates the 'initial' position of the buffer so - * that {@link ReplayingDecoder} rewinds the {@code readerIndex} of the buffer - * to the last position where you called the {@code checkpoint()} method. - * - *

Calling {@code checkpoint(T)} with an {@link Enum}

- *

- * Although you can just use {@code checkpoint()} method and manage the state - * of the decoder by yourself, the easiest way to manage the state of the - * decoder is to create an {@link Enum} type which represents the current state - * of the decoder and to call {@code checkpoint(T)} method whenever the state - * changes. You can have as many states as you want depending on the - * complexity of the message you want to decode: - * - * 

- * public enum MyDecoderState {
- *   READ_LENGTH,
- *   READ_CONTENT;
- * }
- *
- * public class IntegerHeaderFrameDecoder
- *      extends {@link ReplayingDecoder}<MyDecoderState> {
- *
- *   private int length;
- *
- *   public IntegerHeaderFrameDecoder() {
- *     // Set the initial state.
- *     super(MyDecoderState.READ_LENGTH);
- *   }
- *
- *   {@code @Override}
- *   protected void decode({@link ChannelHandlerContext} ctx,
- *                           {@link ByteBuf} buf, List<Object> out) throws Exception {
- *     switch (state()) {
- *     case READ_LENGTH:
- *       length = buf.readInt();
- *       checkpoint(MyDecoderState.READ_CONTENT);
- *     case READ_CONTENT:
- *       ByteBuf frame = buf.readBytes(length);
- *       checkpoint(MyDecoderState.READ_LENGTH);
- *       out.add(frame);
- *       break;
- *     default:
- *       throw new Error("Shouldn't reach here.");
- *     }
- *   }
- * }
- *
- * - *

Calling {@code checkpoint()} with no parameter

- *

- * An alternative way to manage the decoder state is to manage it by yourself. - * 

- * public class IntegerHeaderFrameDecoder
- *      extends {@link ReplayingDecoder}<{@link Void}> {
- *
- *   private boolean readLength;
- *   private int length;
- *
- *   {@code @Override}
- *   protected void decode({@link ChannelHandlerContext} ctx,
- *                           {@link ByteBuf} buf, List<Object> out) throws Exception {
- *     if (!readLength) {
- *       length = buf.readInt();
- *       readLength = true;
- *       checkpoint();
- *     }
- *
- *     if (readLength) {
- *       ByteBuf frame = buf.readBytes(length);
- *       readLength = false;
- *       checkpoint();
- *       out.add(frame);
- *     }
- *   }
- * }
- *
- * - *

Replacing a decoder with another decoder in a pipeline

- *

- * If you are going to write a protocol multiplexer, you will probably want to - * replace a {@link ReplayingDecoder} (protocol detector) with another - * {@link ReplayingDecoder}, {@link ByteToMessageDecoder} or {@link MessageToMessageDecoder} - * (actual protocol decoder). - * It is not possible to achieve this simply by calling - * {@link ChannelPipeline#replace(ChannelHandler, String, ChannelHandler)}, but - * some additional steps are required: - * 

- * public class FirstDecoder extends {@link ReplayingDecoder}<{@link Void}> {
- *
- *     {@code @Override}
- *     protected void decode({@link ChannelHandlerContext} ctx,
- *                             {@link ByteBuf} buf, List<Object> out) {
- *         ...
- *         // Decode the first message
- *         Object firstMessage = ...;
- *
- *         // Add the second decoder
- *         ctx.pipeline().addLast("second", new SecondDecoder());
- *
- *         if (buf.isReadable()) {
- *             // Hand off the remaining data to the second decoder
- *             out.add(firstMessage);
- *             out.add(buf.readBytes(super.actualReadableBytes()));
- *         } else {
- *             // Nothing to hand off
- *             out.add(firstMessage);
- *         }
- *         // Remove the first decoder (me)
- *         ctx.pipeline().remove(this);
- *     }

Parameters that prevents excessive memory consumption

- * - * - * - * - * - * - * - * - * - * - * - * - * - * - * - * - *
NameMeaning
{@code maxInitialLineLength}The maximum length of the initial line - * (e.g. {@code "GET / HTTP/1.0"} or {@code "HTTP/1.0 200 OK"}) - * If the length of the initial line exceeds this value, a - * {@link TooLongFrameException} will be raised.
{@code maxHeaderSize}The maximum length of all headers. If the sum of the length of each - * header exceeds this value, a {@link TooLongFrameException} will be raised.
{@code maxChunkSize}The maximum length of the content or each chunk. If the content length - * (or the length of each chunk) exceeds this value, the content or chunk - * will be split into multiple {@link HttpContent}s whose length is - * {@code maxChunkSize} at maximum.
- * - *

Chunked Content

- * - * If the content of an HTTP message is greater than {@code maxChunkSize} or - * the transfer encoding of the HTTP message is 'chunked', this decoder - * generates one {@link HttpMessage} instance and its following - * {@link HttpContent}s per single HTTP message to avoid excessive memory - * consumption. For example, the following HTTP message: - * 
- * GET / HTTP/1.1
- * Transfer-Encoding: chunked
- *
- * 1a
- * abcdefghijklmnopqrstuvwxyz
- * 10
- * 1234567890abcdef
- * 0
- * Content-MD5: ...
- * [blank line]
- *
- * triggers {@link HttpRequestDecoder} to generate 3 objects: - *
    - *
  1. An {@link HttpRequest},
    2. - *
  2. The first {@link HttpContent} whose content is {@code 'abcdefghijklmnopqrstuvwxyz'},
    3. - *
  3. The second {@link LastHttpContent} whose content is {@code '1234567890abcdef'}, which marks - * the end of the content.
    4. - *
- * - * If you prefer not to handle {@link HttpContent}s by yourself for your - * convenience, insert {@link HttpObjectAggregator} after this decoder in the - * {@link ChannelPipeline}. However, please note that your server might not - * be as memory efficient as without the aggregator. - * - *

Decoding a response for a HEAD request

- *

- * Unlike other HTTP requests, the successful response of a HEAD - * request does not have any content even if there is Content-Length - * header. Because {@link HttpResponseDecoder} is not able to determine if the - * response currently being decoded is associated with a HEAD request, - * you must override {@link #isContentAlwaysEmpty(HttpMessage)} to return - * true for the response of the HEAD request. - *

- * If you are writing an HTTP client that issues a HEAD request, - * please use {@link HttpClientCodec} instead of this decoder. It will perform - * additional state management to handle the responses for HEAD - * requests correctly. - *

- * - *

Decoding a response for a CONNECT request

- *

- * You also need to do additional state management to handle the response of a - * CONNECT request properly, like you did for HEAD. One - * difference is that the decoder should stop decoding completely after decoding - * the successful 200 response since the connection is not an HTTP connection - * anymore. - *

- * {@link HttpClientCodec} also handles this edge case correctly, so you have to - * use {@link HttpClientCodec} if you are writing an HTTP client that issues a - * CONNECT request. - *

    - *

    ChannelTrafficShapingHandler myHandler = new ChannelTrafficShapingHandler();

    - *

    pipeline.addLast(myHandler);

    - * - *

    Note that this handler has a Pipeline Coverage of "one" which means a new handler must be created - * for each new channel as the counter cannot be shared among all channels..

    - * - *

    Other arguments can be passed like write or read limitation (in bytes/s where 0 means no limitation) - * or the check interval (in millisecond) that represents the delay between two computations of the - * bandwidth and so the call back of the doAccounting method (0 means no accounting at all).

    - * - *

    A value of 0 means no accounting for checkInterval. If you need traffic shaping but no such accounting, - * it is recommended to set a positive value, even if it is high since the precision of the - * Traffic Shaping depends on the period where the traffic is computed. The highest the interval, - * the less precise the traffic shaping will be. It is suggested as higher value something close - * to 5 or 10 minutes.

    - * - *

    maxTimeToWait, by default set to 15s, allows to specify an upper bound of time shaping.

    - *
    • - *
  • In your handler, you should consider to use the {@code channel.isWritable()} and - * {@code channelWritabilityChanged(ctx)} to handle writability, or through - * {@code future.addListener(new GenericFutureListener())} on the future returned by - * {@code ctx.write()}.
    • - *

  • You shall also consider to have object size in read or write operations relatively adapted to - * the bandwidth you required: for instance having 10 MB objects for 10KB/s will lead to burst effect, - * while having 100 KB objects for 1 MB/s should be smoothly handle by this TrafficShaping handler.

    • - *

  • Some configuration methods will be taken as best effort, meaning - * that all already scheduled traffics will not be - * changed, but only applied to new traffics.

    - *

    So the expected usage of those methods are to be used not too often, - * accordingly to the traffic shaping configuration.

This implementation of the {@link AbstractTrafficShapingHandler} is for global - * traffic shaping, that is to say a global limitation of the bandwidth, whatever - * the number of opened channels.

- *

Note the index used in {@code OutboundBuffer.setUserDefinedWritability(index, boolean)} is 2.

- * - *

The general use should be as follow:

- *
    - *

  • Create your unique GlobalTrafficShapingHandler like:

    - *

    GlobalTrafficShapingHandler myHandler = new GlobalTrafficShapingHandler(executor);

    - *

    The executor could be the underlying IO worker pool

    - *

    pipeline.addLast(myHandler);

    - * - *

    Note that this handler has a Pipeline Coverage of "all" which means only one such handler must be created - * and shared among all channels as the counter must be shared among all channels.

    - * - *

    Other arguments can be passed like write or read limitation (in bytes/s where 0 means no limitation) - * or the check interval (in millisecond) that represents the delay between two computations of the - * bandwidth and so the call back of the doAccounting method (0 means no accounting at all).

    - * - *

    A value of 0 means no accounting for checkInterval. If you need traffic shaping but no such accounting, - * it is recommended to set a positive value, even if it is high since the precision of the - * Traffic Shaping depends on the period where the traffic is computed. The highest the interval, - * the less precise the traffic shaping will be. It is suggested as higher value something close - * to 5 or 10 minutes.

    - * - *

    maxTimeToWait, by default set to 15s, allows to specify an upper bound of time shaping.

    - *
    • - *
  • In your handler, you should consider to use the {@code channel.isWritable()} and - * {@code channelWritabilityChanged(ctx)} to handle writability, or through - * {@code future.addListener(new GenericFutureListener())} on the future returned by - * {@code ctx.write()}.
    • - *

  • You shall also consider to have object size in read or write operations relatively adapted to - * the bandwidth you required: for instance having 10 MB objects for 10KB/s will lead to burst effect, - * while having 100 KB objects for 1 MB/s should be smoothly handle by this TrafficShaping handler.

    • - *

  • Some configuration methods will be taken as best effort, meaning - * that all already scheduled traffics will not be - * changed, but only applied to new traffics.

    - * So the expected usage of those methods are to be used not too often, - * accordingly to the traffic shaping configuration.
    • - *
- * - * Be sure to call {@link #release()} once this handler is not needed anymore to release all internal resources. - * This will not shutdown the {@link EventExecutor} as it may be shared, so you need to do this by your own. - */ -@Sharable -public class GlobalTrafficShapingHandler extends AbstractTrafficShapingHandler { - /** - * All queues per channel - */ - private final ConcurrentMap channelQueues = PlatformDependent.newConcurrentHashMap(); - - /** - * Global queues size - */ - private final AtomicLong queuesSize = new AtomicLong(); - - /** - * Max size in the list before proposing to stop writing new objects from next handlers - * for all channel (global) - */ - long maxGlobalWriteSize = DEFAULT_MAX_SIZE * 100; // default 400MB - - private static final class PerChannel { - ArrayDeque messagesQueue; - long queueSize; - long lastWriteTimestamp; - long lastReadTimestamp; - } - - /** - * Create the global TrafficCounter. - */ - void createGlobalTrafficCounter(ScheduledExecutorService executor) { - if (executor == null) { - throw new NullPointerException("executor"); - } - TrafficCounter tc = new TrafficCounter(this, executor, "GlobalTC", checkInterval); - setTrafficCounter(tc); - tc.start(); - } - - /** - * Create a new instance. - * - * @param executor - * the {@link ScheduledExecutorService} to use for the {@link TrafficCounter}. - * @param writeLimit - * 0 or a limit in bytes/s - * @param readLimit - * 0 or a limit in bytes/s - * @param checkInterval - * The delay between two computations of performances for - * channels or 0 if no stats are to be computed. - * @param maxTime - * The maximum delay to wait in case of traffic excess. - */ - public GlobalTrafficShapingHandler(ScheduledExecutorService executor, long writeLimit, long readLimit, - long checkInterval, long maxTime) { - super(writeLimit, readLimit, checkInterval, maxTime); - createGlobalTrafficCounter(executor); - } - - /** - * Create a new instance using - * default max time as delay allowed value of 15000 ms. - * - * @param executor - * the {@link ScheduledExecutorService} to use for the {@link TrafficCounter}. - * @param writeLimit - * 0 or a limit in bytes/s - * @param readLimit - * 0 or a limit in bytes/s - * @param checkInterval - * The delay between two computations of performances for - * channels or 0 if no stats are to be computed. - */ - public GlobalTrafficShapingHandler(ScheduledExecutorService executor, long writeLimit, - long readLimit, long checkInterval) { - super(writeLimit, readLimit, checkInterval); - createGlobalTrafficCounter(executor); - } - - /** - * Create a new instance using default Check Interval value of 1000 ms and - * default max time as delay allowed value of 15000 ms. - * - * @param executor - * the {@link ScheduledExecutorService} to use for the {@link TrafficCounter}. - * @param writeLimit - * 0 or a limit in bytes/s - * @param readLimit - * 0 or a limit in bytes/s - */ - public GlobalTrafficShapingHandler(ScheduledExecutorService executor, long writeLimit, - long readLimit) { - super(writeLimit, readLimit); - createGlobalTrafficCounter(executor); - } - - /** - * Create a new instance using - * default max time as delay allowed value of 15000 ms and no limit. - * - * @param executor - * the {@link ScheduledExecutorService} to use for the {@link TrafficCounter}. - * @param checkInterval - * The delay between two computations of performances for - * channels or 0 if no stats are to be computed. - */ - public GlobalTrafficShapingHandler(ScheduledExecutorService executor, long checkInterval) { - super(checkInterval); - createGlobalTrafficCounter(executor); - } - - /** - * Create a new instance using default Check Interval value of 1000 ms and - * default max time as delay allowed value of 15000 ms and no limit. - * - * @param executor - * the {@link ScheduledExecutorService} to use for the {@link TrafficCounter}. - */ - public GlobalTrafficShapingHandler(EventExecutor executor) { - createGlobalTrafficCounter(executor); - } - - /** - * @return the maxGlobalWriteSize default value being 400 MB. - */ - public long getMaxGlobalWriteSize() { - return maxGlobalWriteSize; - } - - /** - * Note the change will be taken as best effort, meaning - * that all already scheduled traffics will not be - * changed, but only applied to new traffics.

The main goal of this package is to allow you to shape the traffic (bandwidth limitation), - * but also to get statistics on how many bytes are read or written. Both functions can - * be active or inactive (traffic or statistics).

- * - *

Two classes implement this behavior: - *

    - *
  • {@link TrafficCounter}: this class implements the counters needed by the handlers. - * It can be accessed to get some extra information like the read or write bytes since last check, the read and write - * bandwidth from last check...
    • - * - *
  • {@link AbstractTrafficShapingHandler}: this abstract class implements the kernel - * of traffic shaping. It could be extended to fit your needs. Two classes are proposed as default - * implementations: see {@link ChannelTrafficShapingHandler} and see {@link GlobalTrafficShapingHandler} - * respectively for Channel traffic shaping and Global traffic shaping.
    • - *

- * - *

Both inbound and outbound traffic can be shaped independently. This is done by either passing in - * the desired limiting values to the constructors of both the Channel and Global traffic shaping handlers, - * or by calling the configure method on the {@link AbstractTrafficShapingHandler}. A value of - * 0 for either parameter indicates that there should be no limitation. This allows you to monitor the - * incoming and outgoing traffic without shaping.

- * - *

To activate or deactivate the statistics, you can adjust the delay to a low (suggested not less than 200ms - * for efficiency reasons) or a high value (let say 24H in millisecond is huge enough to not get the problem) - * or even using 0 which means no computation will be done.

- * - *

If you want to do anything with these statistics, just override the doAccounting method.
- * This interval can be changed either from the method configure in {@link AbstractTrafficShapingHandler} - * or directly using the method configure of {@link TrafficCounter}.

- * - *

Note that a new {@link ChannelTrafficShapingHandler} must be created for each new channel, - * but only one {@link GlobalTrafficShapingHandler} must be created for all channels.

- * - *

Note also that you can create different GlobalTrafficShapingHandler if you want to separate classes of - * channels (for instance either from business point of view or from bind address point of view).

Tick Duration

- * - * As described with 'approximated', this timer does not execute the scheduled - * {@link TimerTask} on time. {@link HashedWheelTimer}, on every tick, will - * check if there are any {@link TimerTask}s behind the schedule and execute - * them. - *

- * You can increase or decrease the accuracy of the execution timing by - * specifying smaller or larger tick duration in the constructor. In most - * network applications, I/O timeout does not need to be accurate. Therefore, - * the default tick duration is 100 milliseconds and you will not need to try - * different configurations in most cases. - * - *

Ticks per Wheel (Wheel Size)

- * - * {@link HashedWheelTimer} maintains a data structure called 'wheel'. - * To put simply, a wheel is a hash table of {@link TimerTask}s whose hash - * function is 'dead line of the task'. The default number of ticks per wheel - * (i.e. the size of the wheel) is 512. You could specify a larger value - * if you are going to schedule a lot of timeouts. - * - *

Do not create many instances.

- * - * {@link HashedWheelTimer} creates a new thread whenever it is instantiated and - * started. Therefore, you should make sure to create only one instance and - * share it across your application. One of the common mistakes, that makes - * your application unresponsive, is to create a new instance for every connection. - * - *

Implementation Details

- * - * {@link HashedWheelTimer} is based on - * George Varghese and - * Tony Lauck's paper, - * 'Hashed - * and Hierarchical Timing Wheels: data structures to efficiently implement a - * timer facility'.

This class obeys the - * same functional specification as {@link java.util.Hashtable}, and - * includes versions of methods corresponding to each method of - * {@code Hashtable}. However, even though all operations are - * thread-safe, retrieval operations do not entail locking, - * and there is not any support for locking the entire table - * in a way that prevents all access. This class is fully - * interoperable with {@code Hashtable} in programs that rely on its - * thread safety but not on its synchronization details. - * - *

Retrieval operations (including {@code get}) generally do not - * block, so may overlap with update operations (including {@code put} - * and {@code remove}). Retrievals reflect the results of the most - * recently completed update operations holding upon their - * onset. (More formally, an update operation for a given key bears a - * happens-before relation with any (non-null) retrieval for - * that key reporting the updated value.) For aggregate operations - * such as {@code putAll} and {@code clear}, concurrent retrievals may - * reflect insertion or removal of only some entries. Similarly, - * Iterators and Enumerations return elements reflecting the state of - * the hash table at some point at or since the creation of the - * iterator/enumeration. They do not throw {@link - * ConcurrentModificationException}. However, iterators are designed - * to be used by only one thread at a time. Bear in mind that the - * results of aggregate status methods including {@code size}, {@code - * isEmpty}, and {@code containsValue} are typically useful only when - * a map is not undergoing concurrent updates in other threads. - * Otherwise the results of these methods reflect transient states - * that may be adequate for monitoring or estimation purposes, but not - * for program control. - * - *

The table is dynamically expanded when there are too many - * collisions (i.e., keys that have distinct hash codes but fall into - * the same slot modulo the table size), with the expected average - * effect of maintaining roughly two bins per mapping (corresponding - * to a 0.75 load factor threshold for resizing). There may be much - * variance around this average as mappings are added and removed, but - * overall, this maintains a commonly accepted time/space tradeoff for - * hash tables. However, resizing this or any other kind of hash - * table may be a relatively slow operation. When possible, it is a - * good idea to provide a size estimate as an optional {@code - * initialCapacity} constructor argument. An additional optional - * {@code loadFactor} constructor argument provides a further means of - * customizing initial table capacity by specifying the table density - * to be used in calculating the amount of space to allocate for the - * given number of elements. Also, for compatibility with previous - * versions of this class, constructors may optionally specify an - * expected {@code concurrencyLevel} as an additional hint for - * internal sizing. Note that using many keys with exactly the same - * {@code hashCode()} is a sure way to slow down performance of any - * hash table. To ameliorate impact, when keys are {@link Comparable}, - * this class may use comparison order among keys to help break ties. - * - *

A {@link Set} projection of a ConcurrentHashMapV8 may be created - * (using {@link #newKeySet()} or {@link #newKeySet(int)}), or viewed - * (using {@link #keySet(Object)} when only keys are of interest, and the - * mapped values are (perhaps transiently) not used or all take the - * same mapping value. - * - *

This class and its views and iterators implement all of the - * optional methods of the {@link Map} and {@link Iterator} - * interfaces. - * - *

Like {@link Hashtable} but unlike {@link HashMap}, this class - * does not allow {@code null} to be used as a key or value. - * - *

ConcurrentHashMapV8s support a set of sequential and parallel bulk - * operations that are designed - * to be safely, and often sensibly, applied even with maps that are - * being concurrently updated by other threads; for example, when - * computing a snapshot summary of the values in a shared registry. - * There are three kinds of operation, each with four forms, accepting - * functions with Keys, Values, Entries, and (Key, Value) arguments - * and/or return values. Because the elements of a ConcurrentHashMapV8 - * are not ordered in any particular way, and may be processed in - * different orders in different parallel executions, the correctness - * of supplied functions should not depend on any ordering, or on any - * other objects or values that may transiently change while - * computation is in progress; and except for forEach actions, should - * ideally be side-effect-free. Bulk operations on {@link java.util.Map.Entry} - * objects do not support method {@code setValue}. - * - *

    - *
  • forEach: Perform a given action on each element. - * A variant form applies a given transformation on each element - * before performing the action.
    • - * - *
  • search: Return the first available non-null result of - * applying a given function on each element; skipping further - * search when a result is found.
    • - * - *
  • reduce: Accumulate each element. The supplied reduction - * function cannot rely on ordering (more formally, it should be - * both associative and commutative). There are five variants: - * - *
      - * - *
    • Plain reductions. (There is not a form of this method for - * (key, value) function arguments since there is no corresponding - * return type.)
      • - * - *
    • Mapped reductions that accumulate the results of a given - * function applied to each element.
      • - * - *
    • Reductions to scalar doubles, longs, and ints, using a - * given basis value.
      • - * - *

- * - *

These bulk operations accept a {@code parallelismThreshold} - * argument. Methods proceed sequentially if the current map size is - * estimated to be less than the given threshold. Using a value of - * {@code Long.MAX_VALUE} suppresses all parallelism. Using a value - * of {@code 1} results in maximal parallelism by partitioning into - * enough subtasks to fully utilize the {@link - * ForkJoinPool#commonPool()} that is used for all parallel - * computations. Normally, you would initially choose one of these - * extreme values, and then measure performance of using in-between - * values that trade off overhead versus throughput. - * - *

The concurrency properties of bulk operations follow - * from those of ConcurrentHashMapV8: Any non-null result returned - * from {@code get(key)} and related access methods bears a - * happens-before relation with the associated insertion or - * update. The result of any bulk operation reflects the - * composition of these per-element relations (but is not - * necessarily atomic with respect to the map as a whole unless it - * is somehow known to be quiescent). Conversely, because keys - * and values in the map are never null, null serves as a reliable - * atomic indicator of the current lack of any result. To - * maintain this property, null serves as an implicit basis for - * all non-scalar reduction operations. For the double, long, and - * int versions, the basis should be one that, when combined with - * any other value, returns that other value (more formally, it - * should be the identity element for the reduction). Most common - * reductions have these properties; for example, computing a sum - * with basis 0 or a minimum with basis MAX_VALUE. - * - *

Search and transformation functions provided as arguments - * should similarly return null to indicate the lack of any result - * (in which case it is not used). In the case of mapped - * reductions, this also enables transformations to serve as - * filters, returning null (or, in the case of primitive - * specializations, the identity basis) if the element should not - * be combined. You can create compound transformations and - * filterings by composing them yourself under this "null means - * there is nothing there now" rule before using them in search or - * reduce operations. - * - *

Methods accepting and/or returning Entry arguments maintain - * key-value associations. They may be useful for example when - * finding the key for the greatest value. Note that "plain" Entry - * arguments can be supplied using {@code new - * AbstractMap.SimpleEntry(k,v)}. - * - *

Bulk operations may complete abruptly, throwing an - * exception encountered in the application of a supplied - * function. Bear in mind when handling such exceptions that other - * concurrently executing functions could also have thrown - * exceptions, or would have done so if the first exception had - * not occurred. - * - *

Speedups for parallel compared to sequential forms are common - * but not guaranteed. Parallel operations involving brief functions - * on small maps may execute more slowly than sequential forms if the - * underlying work to parallelize the computation is more expensive - * than the computation itself. Similarly, parallelization may not - * lead to much actual parallelism if all processors are busy - * performing unrelated tasks. - * - *

All arguments to all task methods must be non-null. - * - *

Secondary goals are to keep space consumption about - * the same or better than java.util.HashMap, and to support high - * initial insertion rates on an empty table by many threads. - * - * This map usually acts as a binned (bucketed) hash table. Each - * key-value mapping is held in a Node. Most nodes are instances - * of the basic Node class with hash, key, value, and next - * fields. However, various subclasses exist: TreeNodes are - * arranged in balanced trees, not lists. TreeBins hold the roots - * of sets of TreeNodes. ForwardingNodes are placed at the heads - * of bins during resizing. ReservationNodes are used as - * placeholders while establishing values in computeIfAbsent and - * related methods. The types TreeBin, ForwardingNode, and - * ReservationNode do not hold normal user keys, values, or - * hashes, and are readily distinguishable during search etc - * because they have negative hash fields and null key and value - * fields. (These special nodes are either uncommon or transient, - * so the impact of carrying around some unused fields is - * insignificant.) - * - * The table is lazily initialized to a power-of-two size upon the - * first insertion. Each bin in the table normally contains a - * list of Nodes (most often, the list has only zero or one Node). - * Table accesses require volatile/atomic reads, writes, and - * CASes. Because there is no other way to arrange this without - * adding further indirections, we use intrinsics - * (sun.misc.Unsafe) operations. - * - * We use the top (sign) bit of Node hash fields for control - * purposes -- it is available anyway because of addressing - * constraints. Nodes with negative hash fields are specially - * handled or ignored in map methods. - * - * Insertion (via put or its variants) of the first node in an - * empty bin is performed by just CASing it to the bin. This is - * by far the most common case for put operations under most - * key/hash distributions. Other update operations (insert, - * delete, and replace) require locks. We do not want to waste - * the space required to associate a distinct lock object with - * each bin, so instead use the first node of a bin list itself as - * a lock. Locking support for these locks relies on builtin - * "synchronized" monitors. - * - * Using the first node of a list as a lock does not by itself - * suffice though: When a node is locked, any update must first - * validate that it is still the first node after locking it, and - * retry if not. Because new nodes are always appended to lists, - * once a node is first in a bin, it remains first until deleted - * or the bin becomes invalidated (upon resizing). - * - * The main disadvantage of per-bin locks is that other update - * operations on other nodes in a bin list protected by the same - * lock can stall, for example when user equals() or mapping - * functions take a long time. However, statistically, under - * random hash codes, this is not a common problem. Ideally, the - * frequency of nodes in bins follows a Poisson distribution - * (http://en.wikipedia.org/wiki/Poisson_distribution) with a - * parameter of about 0.5 on average, given the resizing threshold - * of 0.75, although with a large variance because of resizing - * granularity. Ignoring variance, the expected occurrences of - * list size k are (exp(-0.5) * pow(0.5, k) / factorial(k)). The - * first values are: - * - * 0: 0.60653066 - * 1: 0.30326533 - * 2: 0.07581633 - * 3: 0.01263606 - * 4: 0.00157952 - * 5: 0.00015795 - * 6: 0.00001316 - * 7: 0.00000094 - * 8: 0.00000006 - * more: less than 1 in ten million - * - * Lock contention probability for two threads accessing distinct - * elements is roughly 1 / (8 * #elements) under random hashes. - * - * Actual hash code distributions encountered in practice - * sometimes deviate significantly from uniform randomness. This - * includes the case when N > (1<<30), so some keys MUST collide. - * Similarly for dumb or hostile usages in which multiple keys are - * designed to have identical hash codes or ones that differs only - * in masked-out high bits. So we use a secondary strategy that - * applies when the number of nodes in a bin exceeds a - * threshold. These TreeBins use a balanced tree to hold nodes (a - * specialized form of red-black trees), bounding search time to - * O(log N). Each search step in a TreeBin is at least twice as - * slow as in a regular list, but given that N cannot exceed - * (1<<64) (before running out of addresses) this bounds search - * steps, lock hold times, etc, to reasonable constants (roughly - * 100 nodes inspected per operation worst case) so long as keys - * are Comparable (which is very common -- String, Long, etc). - * TreeBin nodes (TreeNodes) also maintain the same "next" - * traversal pointers as regular nodes, so can be traversed in - * iterators in the same way. - * - * The table is resized when occupancy exceeds a percentage - * threshold (nominally, 0.75, but see below). Any thread - * noticing an overfull bin may assist in resizing after the - * initiating thread allocates and sets up the replacement - * array. However, rather than stalling, these other threads may - * proceed with insertions etc. The use of TreeBins shields us - * from the worst case effects of overfilling while resizes are in - * progress. Resizing proceeds by transferring bins, one by one, - * from the table to the next table. To enable concurrency, the - * next table must be (incrementally) prefilled with place-holders - * serving as reverse forwarders to the old table. Because we are - * using power-of-two expansion, the elements from each bin must - * either stay at same index, or move with a power of two - * offset. We eliminate unnecessary node creation by catching - * cases where old nodes can be reused because their next fields - * won't change. On average, only about one-sixth of them need - * cloning when a table doubles. The nodes they replace will be - * garbage collectable as soon as they are no longer referenced by - * any reader thread that may be in the midst of concurrently - * traversing table. Upon transfer, the old table bin contains - * only a special forwarding node (with hash field "MOVED") that - * contains the next table as its key. On encountering a - * forwarding node, access and update operations restart, using - * the new table. - * - * Each bin transfer requires its bin lock, which can stall - * waiting for locks while resizing. However, because other - * threads can join in and help resize rather than contend for - * locks, average aggregate waits become shorter as resizing - * progresses. The transfer operation must also ensure that all - * accessible bins in both the old and new table are usable by any - * traversal. This is arranged by proceeding from the last bin - * (table.length - 1) up towards the first. Upon seeing a - * forwarding node, traversals (see class Traverser) arrange to - * move to the new table without revisiting nodes. However, to - * ensure that no intervening nodes are skipped, bin splitting can - * only begin after the associated reverse-forwarders are in - * place. - * - * The traversal scheme also applies to partial traversals of - * ranges of bins (via an alternate Traverser constructor) - * to support partitioned aggregate operations. Also, read-only - * operations give up if ever forwarded to a null table, which - * provides support for shutdown-style clearing, which is also not - * currently implemented. - * - * Lazy table initialization minimizes footprint until first use, - * and also avoids resizings when the first operation is from a - * putAll, constructor with map argument, or deserialization. - * These cases attempt to override the initial capacity settings, - * but harmlessly fail to take effect in cases of races. - * - * The element count is maintained using a specialization of - * LongAdder. We need to incorporate a specialization rather than - * just use a LongAdder in order to access implicit - * contention-sensing that leads to creation of multiple - * CounterCells. The counter mechanics avoid contention on - * updates but can encounter cache thrashing if read too - * frequently during concurrent access. To avoid reading so often, - * resizing under contention is attempted only upon adding to a - * bin already holding two or more nodes. Under uniform hash - * distributions, the probability of this occurring at threshold - * is around 13%, meaning that only about 1 in 8 puts check - * threshold (and after resizing, many fewer do so). - * - * TreeBins use a special form of comparison for search and - * related operations (which is the main reason we cannot use - * existing collections such as TreeMaps). TreeBins contain - * Comparable elements, but may contain others, as well as - * elements that are Comparable but not necessarily Comparable - * for the same T, so we cannot invoke compareTo among them. To - * handle this, the tree is ordered primarily by hash value, then - * by Comparable.compareTo order if applicable. On lookup at a - * node, if elements are not comparable or compare as 0 then both - * left and right children may need to be searched in the case of - * tied hash values. (This corresponds to the full list search - * that would be necessary if all elements were non-Comparable and - * had tied hashes.) The red-black balancing code is updated from - * pre-jdk-collections - * (http://gee.cs.oswego.edu/dl/classes/collections/RBCell.java) - * based in turn on Cormen, Leiserson, and Rivest "Introduction to - * Algorithms" (CLR). - * - * TreeBins also require an additional locking mechanism. While - * list traversal is always possible by readers even during - * updates, tree traversal is not, mainly because of tree-rotations - * that may change the root node and/or its linkages. TreeBins - * include a simple read-write lock mechanism parasitic on the - * main bin-synchronization strategy: Structural adjustments - * associated with an insertion or removal are already bin-locked - * (and so cannot conflict with other writers) but must wait for - * ongoing readers to finish. Since there can be only one such - * waiter, we use a simple scheme using a single "waiter" field to - * block writers. However, readers need never block. If the root - * lock is held, they proceed along the slow traversal path (via - * next-pointers) until the lock becomes available or the list is - * exhausted, whichever comes first. These cases are not fast, but - * maximize aggregate expected throughput. - * - * Maintaining API and serialization compatibility with previous - * versions of this class introduces several oddities. Mainly: We - * leave untouched but unused constructor arguments refering to - * concurrencyLevel. We accept a loadFactor constructor argument, - * but apply it only to initial table capacity (which is the only - * time that we can guarantee to honor it.)

Uses of - * CountedCompleter are similar to those of other completion based - * components (such as {@link java.nio.channels.CompletionHandler}) - * except that multiple pending completions may be necessary - * to trigger the completion action {@link #onCompletion(CountedCompleter)}, - * not just one. - * Unless initialized otherwise, the {@linkplain #getPendingCount pending - * count} starts at zero, but may be (atomically) changed using - * methods {@link #setPendingCount}, {@link #addToPendingCount}, and - * {@link #compareAndSetPendingCount}. Upon invocation of {@link - * #tryComplete}, if the pending action count is nonzero, it is - * decremented; otherwise, the completion action is performed, and if - * this completer itself has a completer, the process is continued - * with its completer. As is the case with related synchronization - * components such as {@link java.util.concurrent.Phaser Phaser} and - * {@link java.util.concurrent.Semaphore Semaphore}, these methods - * affect only internal counts; they do not establish any further - * internal bookkeeping. In particular, the identities of pending - * tasks are not maintained. As illustrated below, you can create - * subclasses that do record some or all pending tasks or their - * results when needed. As illustrated below, utility methods - * supporting customization of completion traversals are also - * provided. However, because CountedCompleters provide only basic - * synchronization mechanisms, it may be useful to create further - * abstract subclasses that maintain linkages, fields, and additional - * support methods appropriate for a set of related usages. - * - *

A concrete CountedCompleter class must define method {@link - * #compute}, that should in most cases (as illustrated below), invoke - * {@code tryComplete()} once before returning. The class may also - * optionally override method {@link #onCompletion(CountedCompleter)} - * to perform an action upon normal completion, and method - * {@link #onExceptionalCompletion(Throwable, CountedCompleter)} to - * perform an action upon any exception. - * - *

CountedCompleters most often do not bear results, in which case - * they are normally declared as {@code CountedCompleter}, and - * will always return {@code null} as a result value. In other cases, - * you should override method {@link #getRawResult} to provide a - * result from {@code join(), invoke()}, and related methods. In - * general, this method should return the value of a field (or a - * function of one or more fields) of the CountedCompleter object that - * holds the result upon completion. Method {@link #setRawResult} by - * default plays no role in CountedCompleters. It is possible, but - * rarely applicable, to override this method to maintain other - * objects or fields holding result data. - * - *

A CountedCompleter that does not itself have a completer (i.e., - * one for which {@link #getCompleter} returns {@code null}) can be - * used as a regular ForkJoinTask with this added functionality. - * However, any completer that in turn has another completer serves - * only as an internal helper for other computations, so its own task - * status (as reported in methods such as {@link ForkJoinTask#isDone}) - * is arbitrary; this status changes only upon explicit invocations of - * {@link #complete}, {@link ForkJoinTask#cancel}, - * {@link ForkJoinTask#completeExceptionally(Throwable)} or upon - * exceptional completion of method {@code compute}. Upon any - * exceptional completion, the exception may be relayed to a task's - * completer (and its completer, and so on), if one exists and it has - * not otherwise already completed. Similarly, cancelling an internal - * CountedCompleter has only a local effect on that completer, so is - * not often useful. - * - *

Sample Usages. - * - *

Parallel recursive decomposition. CountedCompleters may - * be arranged in trees similar to those often used with {@link - * RecursiveAction}s, although the constructions involved in setting - * them up typically vary. Here, the completer of each task is its - * parent in the computation tree. Even though they entail a bit more - * bookkeeping, CountedCompleters may be better choices when applying - * a possibly time-consuming operation (that cannot be further - * subdivided) to each element of an array or collection; especially - * when the operation takes a significantly different amount of time - * to complete for some elements than others, either because of - * intrinsic variation (for example I/O) or auxiliary effects such as - * garbage collection. Because CountedCompleters provide their own - * continuations, other threads need not block waiting to perform - * them. - * - *

For example, here is an initial version of a class that uses - * divide-by-two recursive decomposition to divide work into single - * pieces (leaf tasks). Even when work is split into individual calls, - * tree-based techniques are usually preferable to directly forking - * leaf tasks, because they reduce inter-thread communication and - * improve load balancing. In the recursive case, the second of each - * pair of subtasks to finish triggers completion of its parent - * (because no result combination is performed, the default no-op - * implementation of method {@code onCompletion} is not overridden). - * A static utility method sets up the base task and invokes it - * (here, implicitly using the {@link ForkJoinPool#commonPool()}). - * - * 

 {@code
- * class MyOperation { void apply(E e) { ... }  }
- *
- * class ForEach extends CountedCompleter {
- *
- *   public static  void forEach(E[] array, MyOperation op) {
- *     new ForEach(null, array, op, 0, array.length).invoke();
- *   }
- *
- *   final E[] array; final MyOperation op; final int lo, hi;
- *   ForEach(CountedCompleter p, E[] array, MyOperation op, int lo, int hi) {
- *     super(p);
- *     this.array = array; this.op = op; this.lo = lo; this.hi = hi;
- *   }
- *
- *   public void compute() { // version 1
- *     if (hi - lo >= 2) {
- *       int mid = (lo + hi) >>> 1;
- *       setPendingCount(2); // must set pending count before fork
- *       new ForEach(this, array, op, mid, hi).fork(); // right child
- *       new ForEach(this, array, op, lo, mid).fork(); // left child
- *     }
- *     else if (hi > lo)
- *       op.apply(array[lo]);
- *     tryComplete();
- *   }
- * }}
- * - * This design can be improved by noticing that in the recursive case, - * the task has nothing to do after forking its right task, so can - * directly invoke its left task before returning. (This is an analog - * of tail recursion removal.) Also, because the task returns upon - * executing its left task (rather than falling through to invoke - * {@code tryComplete}) the pending count is set to one: - * - * 
 {@code
- * class ForEach ...
- *   public void compute() { // version 2
- *     if (hi - lo >= 2) {
- *       int mid = (lo + hi) >>> 1;
- *       setPendingCount(1); // only one pending
- *       new ForEach(this, array, op, mid, hi).fork(); // right child
- *       new ForEach(this, array, op, lo, mid).compute(); // direct invoke
- *     }
- *     else {
- *       if (hi > lo)
- *         op.apply(array[lo]);
- *       tryComplete();
- *     }
- *   }
- * }
- * - * As a further improvement, notice that the left task need not even exist. - * Instead of creating a new one, we can iterate using the original task, - * and add a pending count for each fork. Additionally, because no task - * in this tree implements an {@link #onCompletion(CountedCompleter)} method, - * {@code tryComplete()} can be replaced with {@link #propagateCompletion}. - * - * 
 {@code
- * class ForEach ...
- *   public void compute() { // version 3
- *     int l = lo,  h = hi;
- *     while (h - l >= 2) {
- *       int mid = (l + h) >>> 1;
- *       addToPendingCount(1);
- *       new ForEach(this, array, op, mid, h).fork(); // right child
- *       h = mid;
- *     }
- *     if (h > l)
- *       op.apply(array[l]);
- *     propagateCompletion();
- *   }
- * }
- * - * Additional improvements of such classes might entail precomputing - * pending counts so that they can be established in constructors, - * specializing classes for leaf steps, subdividing by say, four, - * instead of two per iteration, and using an adaptive threshold - * instead of always subdividing down to single elements. - * - *

Searching. A tree of CountedCompleters can search for a - * value or property in different parts of a data structure, and - * report a result in an {@link - * java.util.concurrent.atomic.AtomicReference AtomicReference} as - * soon as one is found. The others can poll the result to avoid - * unnecessary work. (You could additionally {@linkplain #cancel - * cancel} other tasks, but it is usually simpler and more efficient - * to just let them notice that the result is set and if so skip - * further processing.) Illustrating again with an array using full - * partitioning (again, in practice, leaf tasks will almost always - * process more than one element): - * - * 

 {@code
- * class Searcher extends CountedCompleter {
- *   final E[] array; final AtomicReference result; final int lo, hi;
- *   Searcher(CountedCompleter p, E[] array, AtomicReference result, int lo, int hi) {
- *     super(p);
- *     this.array = array; this.result = result; this.lo = lo; this.hi = hi;
- *   }
- *   public E getRawResult() { return result.get(); }
- *   public void compute() { // similar to ForEach version 3
- *     int l = lo,  h = hi;
- *     while (result.get() == null && h >= l) {
- *       if (h - l >= 2) {
- *         int mid = (l + h) >>> 1;
- *         addToPendingCount(1);
- *         new Searcher(this, array, result, mid, h).fork();
- *         h = mid;
- *       }
- *       else {
- *         E x = array[l];
- *         if (matches(x) && result.compareAndSet(null, x))
- *           quietlyCompleteRoot(); // root task is now joinable
- *         break;
- *       }
- *     }
- *     tryComplete(); // normally complete whether or not found
- *   }
- *   boolean matches(E e) { ... } // return true if found
- *
- *   public static  E search(E[] array) {
- *       return new Searcher(null, array, new AtomicReference(), 0, array.length).invoke();
- *   }
- * }}
- * - * In this example, as well as others in which tasks have no other - * effects except to compareAndSet a common result, the trailing - * unconditional invocation of {@code tryComplete} could be made - * conditional ({@code if (result.get() == null) tryComplete();}) - * because no further bookkeeping is required to manage completions - * once the root task completes. - * - *

Recording subtasks. CountedCompleter tasks that combine - * results of multiple subtasks usually need to access these results - * in method {@link #onCompletion(CountedCompleter)}. As illustrated in the following - * class (that performs a simplified form of map-reduce where mappings - * and reductions are all of type {@code E}), one way to do this in - * divide and conquer designs is to have each subtask record its - * sibling, so that it can be accessed in method {@code onCompletion}. - * This technique applies to reductions in which the order of - * combining left and right results does not matter; ordered - * reductions require explicit left/right designations. Variants of - * other streamlinings seen in the above examples may also apply. - * - * 

 {@code
- * class MyMapper { E apply(E v) {  ...  } }
- * class MyReducer { E apply(E x, E y) {  ...  } }
- * class MapReducer extends CountedCompleter {
- *   final E[] array; final MyMapper mapper;
- *   final MyReducer reducer; final int lo, hi;
- *   MapReducer sibling;
- *   E result;
- *   MapReducer(CountedCompleter p, E[] array, MyMapper mapper,
- *              MyReducer reducer, int lo, int hi) {
- *     super(p);
- *     this.array = array; this.mapper = mapper;
- *     this.reducer = reducer; this.lo = lo; this.hi = hi;
- *   }
- *   public void compute() {
- *     if (hi - lo >= 2) {
- *       int mid = (lo + hi) >>> 1;
- *       MapReducer left = new MapReducer(this, array, mapper, reducer, lo, mid);
- *       MapReducer right = new MapReducer(this, array, mapper, reducer, mid, hi);
- *       left.sibling = right;
- *       right.sibling = left;
- *       setPendingCount(1); // only right is pending
- *       right.fork();
- *       left.compute();     // directly execute left
- *     }
- *     else {
- *       if (hi > lo)
- *           result = mapper.apply(array[lo]);
- *       tryComplete();
- *     }
- *   }
- *   public void onCompletion(CountedCompleter caller) {
- *     if (caller != this) {
- *       MapReducer child = (MapReducer)caller;
- *       MapReducer sib = child.sibling;
- *       if (sib == null || sib.result == null)
- *         result = child.result;
- *       else
- *         result = reducer.apply(child.result, sib.result);
- *     }
- *   }
- *   public E getRawResult() { return result; }
- *
- *   public static  E mapReduce(E[] array, MyMapper mapper, MyReducer reducer) {
- *     return new MapReducer(null, array, mapper, reducer,
- *                              0, array.length).invoke();
- *   }
- * }}
- * - * Here, method {@code onCompletion} takes a form common to many - * completion designs that combine results. This callback-style method - * is triggered once per task, in either of the two different contexts - * in which the pending count is, or becomes, zero: (1) by a task - * itself, if its pending count is zero upon invocation of {@code - * tryComplete}, or (2) by any of its subtasks when they complete and - * decrement the pending count to zero. The {@code caller} argument - * distinguishes cases. Most often, when the caller is {@code this}, - * no action is necessary. Otherwise the caller argument can be used - * (usually via a cast) to supply a value (and/or links to other - * values) to be combined. Assuming proper use of pending counts, the - * actions inside {@code onCompletion} occur (once) upon completion of - * a task and its subtasks. No additional synchronization is required - * within this method to ensure thread safety of accesses to fields of - * this task or other completed tasks. - * - *

Completion Traversals. If using {@code onCompletion} to - * process completions is inapplicable or inconvenient, you can use - * methods {@link #firstComplete} and {@link #nextComplete} to create - * custom traversals. For example, to define a MapReducer that only - * splits out right-hand tasks in the form of the third ForEach - * example, the completions must cooperatively reduce along - * unexhausted subtask links, which can be done as follows: - * - * 

 {@code
- * class MapReducer extends CountedCompleter { // version 2
- *   final E[] array; final MyMapper mapper;
- *   final MyReducer reducer; final int lo, hi;
- *   MapReducer forks, next; // record subtask forks in list
- *   E result;
- *   MapReducer(CountedCompleter p, E[] array, MyMapper mapper,
- *              MyReducer reducer, int lo, int hi, MapReducer next) {
- *     super(p);
- *     this.array = array; this.mapper = mapper;
- *     this.reducer = reducer; this.lo = lo; this.hi = hi;
- *     this.next = next;
- *   }
- *   public void compute() {
- *     int l = lo,  h = hi;
- *     while (h - l >= 2) {
- *       int mid = (l + h) >>> 1;
- *       addToPendingCount(1);
- *       (forks = new MapReducer(this, array, mapper, reducer, mid, h, forks)).fork();
- *       h = mid;
- *     }
- *     if (h > l)
- *       result = mapper.apply(array[l]);
- *     // process completions by reducing along and advancing subtask links
- *     for (CountedCompleter c = firstComplete(); c != null; c = c.nextComplete()) {
- *       for (MapReducer t = (MapReducer)c, s = t.forks;  s != null; s = t.forks = s.next)
- *         t.result = reducer.apply(t.result, s.result);
- *     }
- *   }
- *   public E getRawResult() { return result; }
- *
- *   public static  E mapReduce(E[] array, MyMapper mapper, MyReducer reducer) {
- *     return new MapReducer(null, array, mapper, reducer,
- *                              0, array.length, null).invoke();
- *   }
- * }}
- * - *

Triggers. Some CountedCompleters are themselves never - * forked, but instead serve as bits of plumbing in other designs; - * including those in which the completion of one or more async tasks - * triggers another async task. For example: - * - * 

 {@code
- * class HeaderBuilder extends CountedCompleter<...> { ... }
- * class BodyBuilder extends CountedCompleter<...> { ... }
- * class PacketSender extends CountedCompleter<...> {
- *   PacketSender(...) { super(null, 1); ... } // trigger on second completion
- *   public void compute() { } // never called
- *   public void onCompletion(CountedCompleter caller) { sendPacket(); }
- * }
- * // sample use:
- * PacketSender p = new PacketSender();
- * new HeaderBuilder(p, ...).fork();
- * new BodyBuilder(p, ...).fork();
- * }

A {@code ForkJoinPool} differs from other kinds of {@link - * ExecutorService} mainly by virtue of employing - * work-stealing: all threads in the pool attempt to find and - * execute tasks submitted to the pool and/or created by other active - * tasks (eventually blocking waiting for work if none exist). This - * enables efficient processing when most tasks spawn other subtasks - * (as do most {@code ForkJoinTask}s), as well as when many small - * tasks are submitted to the pool from external clients. Especially - * when setting asyncMode to true in constructors, {@code - * ForkJoinPool}s may also be appropriate for use with event-style - * tasks that are never joined. - * - *

A static {@link #commonPool()} is available and appropriate for - * most applications. The common pool is used by any ForkJoinTask that - * is not explicitly submitted to a specified pool. Using the common - * pool normally reduces resource usage (its threads are slowly - * reclaimed during periods of non-use, and reinstated upon subsequent - * use). - * - *

For applications that require separate or custom pools, a {@code - * ForkJoinPool} may be constructed with a given target parallelism - * level; by default, equal to the number of available processors. The - * pool attempts to maintain enough active (or available) threads by - * dynamically adding, suspending, or resuming internal worker - * threads, even if some tasks are stalled waiting to join others. - * However, no such adjustments are guaranteed in the face of blocked - * I/O or other unmanaged synchronization. The nested {@link - * ManagedBlocker} interface enables extension of the kinds of - * synchronization accommodated. - * - *

In addition to execution and lifecycle control methods, this - * class provides status check methods (for example - * {@link #getStealCount}) that are intended to aid in developing, - * tuning, and monitoring fork/join applications. Also, method - * {@link #toString} returns indications of pool state in a - * convenient form for informal monitoring. - * - *

As is the case with other ExecutorServices, there are three - * main task execution methods summarized in the following table. - * These are designed to be used primarily by clients not already - * engaged in fork/join computations in the current pool. The main - * forms of these methods accept instances of {@code ForkJoinTask}, - * but overloaded forms also allow mixed execution of plain {@code - * Runnable}- or {@code Callable}- based activities as well. However, - * tasks that are already executing in a pool should normally instead - * use the within-computation forms listed in the table unless using - * async event-style tasks that are not usually joined, in which case - * there is little difference among choice of methods. - * - * - * - * - * - * - * - * - * - * - * - * - * - * - * - * - * - * - * - * - * - * - * - *

The common pool is by default constructed with default - * parameters, but these may be controlled by setting three - * {@linkplain System#getProperty system properties}: - *

    - *
  • {@code java.util.concurrent.ForkJoinPool.common.parallelism} - * - the parallelism level, a non-negative integer - *
  • {@code java.util.concurrent.ForkJoinPool.common.threadFactory} - * - the class name of a {@link ForkJoinWorkerThreadFactory} - *
  • {@code java.util.concurrent.ForkJoinPool.common.exceptionHandler} - * - the class name of a {@link UncaughtExceptionHandler} - *
- * The system class loader is used to load these classes. - * Upon any error in establishing these settings, default parameters - * are used. It is possible to disable or limit the use of threads in - * the common pool by setting the parallelism property to zero, and/or - * using a factory that may return {@code null}. - * - *

Implementation notes: This implementation restricts the - * maximum number of running threads to 32767. Attempts to create - * pools with greater than the maximum number result in - * {@code IllegalArgumentException}. - * - *

This implementation rejects submitted tasks (that is, by throwing - * {@link RejectedExecutionException}) only when the pool is shut down - * or internal resources have been exhausted. - * - * @since 1.7 - * @author Doug Lea - */ -@SuppressWarnings("all") -public class ForkJoinPool extends AbstractExecutorService { - - /* - * Implementation Overview - * - * This class and its nested classes provide the main - * functionality and control for a set of worker threads: - * Submissions from non-FJ threads enter into submission queues. - * Workers take these tasks and typically split them into subtasks - * that may be stolen by other workers. Preference rules give - * first priority to processing tasks from their own queues (LIFO - * or FIFO, depending on mode), then to randomized FIFO steals of - * tasks in other queues. - * - * WorkQueues - * ========== - * - * Most operations occur within work-stealing queues (in nested - * class WorkQueue). These are special forms of Deques that - * support only three of the four possible end-operations -- push, - * pop, and poll (aka steal), under the further constraints that - * push and pop are called only from the owning thread (or, as - * extended here, under a lock), while poll may be called from - * other threads. (If you are unfamiliar with them, you probably - * want to read Herlihy and Shavit's book "The Art of - * Multiprocessor programming", chapter 16 describing these in - * more detail before proceeding.) The main work-stealing queue - * design is roughly similar to those in the papers "Dynamic - * Circular Work-Stealing Deque" by Chase and Lev, SPAA 2005 - * (http://research.sun.com/scalable/pubs/index.html) and - * "Idempotent work stealing" by Michael, Saraswat, and Vechev, - * PPoPP 2009 (http://portal.acm.org/citation.cfm?id=1504186). - * See also "Correct and Efficient Work-Stealing for Weak Memory - * Models" by Le, Pop, Cohen, and Nardelli, PPoPP 2013 - * (http://www.di.ens.fr/~zappa/readings/ppopp13.pdf) for an - * analysis of memory ordering (atomic, volatile etc) issues. The - * main differences ultimately stem from GC requirements that we - * null out taken slots as soon as we can, to maintain as small a - * footprint as possible even in programs generating huge numbers - * of tasks. To accomplish this, we shift the CAS arbitrating pop - * vs poll (steal) from being on the indices ("base" and "top") to - * the slots themselves. So, both a successful pop and poll - * mainly entail a CAS of a slot from non-null to null. Because - * we rely on CASes of references, we do not need tag bits on base - * or top. They are simple ints as used in any circular - * array-based queue (see for example ArrayDeque). Updates to the - * indices must still be ordered in a way that guarantees that top - * == base means the queue is empty, but otherwise may err on the - * side of possibly making the queue appear nonempty when a push, - * pop, or poll have not fully committed. Note that this means - * that the poll operation, considered individually, is not - * wait-free. One thief cannot successfully continue until another - * in-progress one (or, if previously empty, a push) completes. - * However, in the aggregate, we ensure at least probabilistic - * non-blockingness. If an attempted steal fails, a thief always - * chooses a different random victim target to try next. So, in - * order for one thief to progress, it suffices for any - * in-progress poll or new push on any empty queue to - * complete. (This is why we normally use method pollAt and its - * variants that try once at the apparent base index, else - * consider alternative actions, rather than method poll.) - * - * This approach also enables support of a user mode in which local - * task processing is in FIFO, not LIFO order, simply by using - * poll rather than pop. This can be useful in message-passing - * frameworks in which tasks are never joined. However neither - * mode considers affinities, loads, cache localities, etc, so - * rarely provide the best possible performance on a given - * machine, but portably provide good throughput by averaging over - * these factors. (Further, even if we did try to use such - * information, we do not usually have a basis for exploiting it. - * For example, some sets of tasks profit from cache affinities, - * but others are harmed by cache pollution effects.) - * - * WorkQueues are also used in a similar way for tasks submitted - * to the pool. We cannot mix these tasks in the same queues used - * for work-stealing (this would contaminate lifo/fifo - * processing). Instead, we randomly associate submission queues - * with submitting threads, using a form of hashing. The - * Submitter probe value serves as a hash code for - * choosing existing queues, and may be randomly repositioned upon - * contention with other submitters. In essence, submitters act - * like workers except that they are restricted to executing local - * tasks that they submitted (or in the case of CountedCompleters, - * others with the same root task). However, because most - * shared/external queue operations are more expensive than - * internal, and because, at steady state, external submitters - * will compete for CPU with workers, ForkJoinTask.join and - * related methods disable them from repeatedly helping to process - * tasks if all workers are active. Insertion of tasks in shared - * mode requires a lock (mainly to protect in the case of - * resizing) but we use only a simple spinlock (using bits in - * field qlock), because submitters encountering a busy queue move - * on to try or create other queues -- they block only when - * creating and registering new queues. - * - * Management - * ========== - * - * The main throughput advantages of work-stealing stem from - * decentralized control -- workers mostly take tasks from - * themselves or each other. We cannot negate this in the - * implementation of other management responsibilities. The main - * tactic for avoiding bottlenecks is packing nearly all - * essentially atomic control state into two volatile variables - * that are by far most often read (not written) as status and - * consistency checks. - * - * Field "ctl" contains 64 bits holding all the information needed - * to atomically decide to add, inactivate, enqueue (on an event - * queue), dequeue, and/or re-activate workers. To enable this - * packing, we restrict maximum parallelism to (1<<15)-1 (which is - * far in excess of normal operating range) to allow ids, counts, - * and their negations (used for thresholding) to fit into 16bit - * fields. - * - * Field "plock" is a form of sequence lock with a saturating - * shutdown bit (similarly for per-queue "qlocks"), mainly - * protecting updates to the workQueues array, as well as to - * enable shutdown. When used as a lock, it is normally only very - * briefly held, so is nearly always available after at most a - * brief spin, but we use a monitor-based backup strategy to - * block when needed. - * - * Recording WorkQueues. WorkQueues are recorded in the - * "workQueues" array that is created upon first use and expanded - * if necessary. Updates to the array while recording new workers - * and unrecording terminated ones are protected from each other - * by a lock but the array is otherwise concurrently readable, and - * accessed directly. To simplify index-based operations, the - * array size is always a power of two, and all readers must - * tolerate null slots. Worker queues are at odd indices. Shared - * (submission) queues are at even indices, up to a maximum of 64 - * slots, to limit growth even if array needs to expand to add - * more workers. Grouping them together in this way simplifies and - * speeds up task scanning. - * - * All worker thread creation is on-demand, triggered by task - * submissions, replacement of terminated workers, and/or - * compensation for blocked workers. However, all other support - * code is set up to work with other policies. To ensure that we - * do not hold on to worker references that would prevent GC, ALL - * accesses to workQueues are via indices into the workQueues - * array (which is one source of some of the messy code - * constructions here). In essence, the workQueues array serves as - * a weak reference mechanism. Thus for example the wait queue - * field of ctl stores indices, not references. Access to the - * workQueues in associated methods (for example signalWork) must - * both index-check and null-check the IDs. All such accesses - * ignore bad IDs by returning out early from what they are doing, - * since this can only be associated with termination, in which - * case it is OK to give up. All uses of the workQueues array - * also check that it is non-null (even if previously - * non-null). This allows nulling during termination, which is - * currently not necessary, but remains an option for - * resource-revocation-based shutdown schemes. It also helps - * reduce JIT issuance of uncommon-trap code, which tends to - * unnecessarily complicate control flow in some methods. - * - * Event Queuing. Unlike HPC work-stealing frameworks, we cannot - * let workers spin indefinitely scanning for tasks when none can - * be found immediately, and we cannot start/resume workers unless - * there appear to be tasks available. On the other hand, we must - * quickly prod them into action when new tasks are submitted or - * generated. In many usages, ramp-up time to activate workers is - * the main limiting factor in overall performance (this is - * compounded at program start-up by JIT compilation and - * allocation). So we try to streamline this as much as possible. - * We park/unpark workers after placing in an event wait queue - * when they cannot find work. This "queue" is actually a simple - * Treiber stack, headed by the "id" field of ctl, plus a 15bit - * counter value (that reflects the number of times a worker has - * been inactivated) to avoid ABA effects (we need only as many - * version numbers as worker threads). Successors are held in - * field WorkQueue.nextWait. Queuing deals with several intrinsic - * races, mainly that a task-producing thread can miss seeing (and - * signalling) another thread that gave up looking for work but - * has not yet entered the wait queue. We solve this by requiring - * a full sweep of all workers (via repeated calls to method - * scan()) both before and after a newly waiting worker is added - * to the wait queue. Because enqueued workers may actually be - * rescanning rather than waiting, we set and clear the "parker" - * field of WorkQueues to reduce unnecessary calls to unpark. - * (This requires a secondary recheck to avoid missed signals.) - * Note the unusual conventions about Thread.interrupts - * surrounding parking and other blocking: Because interrupts are - * used solely to alert threads to check termination, which is - * checked anyway upon blocking, we clear status (using - * Thread.interrupted) before any call to park, so that park does - * not immediately return due to status being set via some other - * unrelated call to interrupt in user code. - * - * Signalling. We create or wake up workers only when there - * appears to be at least one task they might be able to find and - * execute. When a submission is added or another worker adds a - * task to a queue that has fewer than two tasks, they signal - * waiting workers (or trigger creation of new ones if fewer than - * the given parallelism level -- signalWork). These primary - * signals are buttressed by others whenever other threads remove - * a task from a queue and notice that there are other tasks there - * as well. So in general, pools will be over-signalled. On most - * platforms, signalling (unpark) overhead time is noticeably - * long, and the time between signalling a thread and it actually - * making progress can be very noticeably long, so it is worth - * offloading these delays from critical paths as much as - * possible. Additionally, workers spin-down gradually, by staying - * alive so long as they see the ctl state changing. Similar - * stability-sensing techniques are also used before blocking in - * awaitJoin and helpComplete. - * - * Trimming workers. To release resources after periods of lack of - * use, a worker starting to wait when the pool is quiescent will - * time out and terminate if the pool has remained quiescent for a - * given period -- a short period if there are more threads than - * parallelism, longer as the number of threads decreases. This - * will slowly propagate, eventually terminating all workers after - * periods of non-use. - * - * Shutdown and Termination. A call to shutdownNow atomically sets - * a plock bit and then (non-atomically) sets each worker's - * qlock status, cancels all unprocessed tasks, and wakes up - * all waiting workers. Detecting whether termination should - * commence after a non-abrupt shutdown() call requires more work - * and bookkeeping. We need consensus about quiescence (i.e., that - * there is no more work). The active count provides a primary - * indication but non-abrupt shutdown still requires a rechecking - * scan for any workers that are inactive but not queued. - * - * Joining Tasks - * ============= - * - * Any of several actions may be taken when one worker is waiting - * to join a task stolen (or always held) by another. Because we - * are multiplexing many tasks on to a pool of workers, we can't - * just let them block (as in Thread.join). We also cannot just - * reassign the joiner's run-time stack with another and replace - * it later, which would be a form of "continuation", that even if - * possible is not necessarily a good idea since we sometimes need - * both an unblocked task and its continuation to progress. - * Instead we combine two tactics: - * - * Helping: Arranging for the joiner to execute some task that it - * would be running if the steal had not occurred. - * - * Compensating: Unless there are already enough live threads, - * method tryCompensate() may create or re-activate a spare - * thread to compensate for blocked joiners until they unblock. - * - * A third form (implemented in tryRemoveAndExec) amounts to - * helping a hypothetical compensator: If we can readily tell that - * a possible action of a compensator is to steal and execute the - * task being joined, the joining thread can do so directly, - * without the need for a compensation thread (although at the - * expense of larger run-time stacks, but the tradeoff is - * typically worthwhile). - * - * The ManagedBlocker extension API can't use helping so relies - * only on compensation in method awaitBlocker. - * - * The algorithm in tryHelpStealer entails a form of "linear" - * helping: Each worker records (in field currentSteal) the most - * recent task it stole from some other worker. Plus, it records - * (in field currentJoin) the task it is currently actively - * joining. Method tryHelpStealer uses these markers to try to - * find a worker to help (i.e., steal back a task from and execute - * it) that could hasten completion of the actively joined task. - * In essence, the joiner executes a task that would be on its own - * local deque had the to-be-joined task not been stolen. This may - * be seen as a conservative variant of the approach in Wagner & - * Calder "Leapfrogging: a portable technique for implementing - * efficient futures" SIGPLAN Notices, 1993 - * (http://portal.acm.org/citation.cfm?id=155354). It differs in - * that: (1) We only maintain dependency links across workers upon - * steals, rather than use per-task bookkeeping. This sometimes - * requires a linear scan of workQueues array to locate stealers, - * but often doesn't because stealers leave hints (that may become - * stale/wrong) of where to locate them. It is only a hint - * because a worker might have had multiple steals and the hint - * records only one of them (usually the most current). Hinting - * isolates cost to when it is needed, rather than adding to - * per-task overhead. (2) It is "shallow", ignoring nesting and - * potentially cyclic mutual steals. (3) It is intentionally - * racy: field currentJoin is updated only while actively joining, - * which means that we miss links in the chain during long-lived - * tasks, GC stalls etc (which is OK since blocking in such cases - * is usually a good idea). (4) We bound the number of attempts - * to find work (see MAX_HELP) and fall back to suspending the - * worker and if necessary replacing it with another. - * - * Helping actions for CountedCompleters are much simpler: Method - * helpComplete can take and execute any task with the same root - * as the task being waited on. However, this still entails some - * traversal of completer chains, so is less efficient than using - * CountedCompleters without explicit joins. - * - * It is impossible to keep exactly the target parallelism number - * of threads running at any given time. Determining the - * existence of conservatively safe helping targets, the - * availability of already-created spares, and the apparent need - * to create new spares are all racy, so we rely on multiple - * retries of each. Compensation in the apparent absence of - * helping opportunities is challenging to control on JVMs, where - * GC and other activities can stall progress of tasks that in - * turn stall out many other dependent tasks, without us being - * able to determine whether they will ever require compensation. - * Even though work-stealing otherwise encounters little - * degradation in the presence of more threads than cores, - * aggressively adding new threads in such cases entails risk of - * unwanted positive feedback control loops in which more threads - * cause more dependent stalls (as well as delayed progress of - * unblocked threads to the point that we know they are available) - * leading to more situations requiring more threads, and so - * on. This aspect of control can be seen as an (analytically - * intractable) game with an opponent that may choose the worst - * (for us) active thread to stall at any time. We take several - * precautions to bound losses (and thus bound gains), mainly in - * methods tryCompensate and awaitJoin. - * - * Common Pool - * =========== - * - * The static common pool always exists after static - * initialization. Since it (or any other created pool) need - * never be used, we minimize initial construction overhead and - * footprint to the setup of about a dozen fields, with no nested - * allocation. Most bootstrapping occurs within method - * fullExternalPush during the first submission to the pool. - * - * When external threads submit to the common pool, they can - * perform subtask processing (see externalHelpJoin and related - * methods). This caller-helps policy makes it sensible to set - * common pool parallelism level to one (or more) less than the - * total number of available cores, or even zero for pure - * caller-runs. We do not need to record whether external - * submissions are to the common pool -- if not, externalHelpJoin - * returns quickly (at the most helping to signal some common pool - * workers). These submitters would otherwise be blocked waiting - * for completion, so the extra effort (with liberally sprinkled - * task status checks) in inapplicable cases amounts to an odd - * form of limited spin-wait before blocking in ForkJoinTask.join. - * - * Style notes - * =========== - * - * There is a lot of representation-level coupling among classes - * ForkJoinPool, ForkJoinWorkerThread, and ForkJoinTask. The - * fields of WorkQueue maintain data structures managed by - * ForkJoinPool, so are directly accessed. There is little point - * trying to reduce this, since any associated future changes in - * representations will need to be accompanied by algorithmic - * changes anyway. Several methods intrinsically sprawl because - * they must accumulate sets of consistent reads of volatiles held - * in local variables. Methods signalWork() and scan() are the - * main bottlenecks, so are especially heavily - * micro-optimized/mangled. There are lots of inline assignments - * (of form "while ((local = field) != 0)") which are usually the - * simplest way to ensure the required read orderings (which are - * sometimes critical). This leads to a "C"-like style of listing - * declarations of these locals at the heads of methods or blocks. - * There are several occurrences of the unusual "do {} while - * (!cas...)" which is the simplest way to force an update of a - * CAS'ed variable. There are also other coding oddities (including - * several unnecessary-looking hoisted null checks) that help - * some methods perform reasonably even when interpreted (not - * compiled). - * - * The order of declarations in this file is: - * (1) Static utility functions - * (2) Nested (static) classes - * (3) Static fields - * (4) Fields, along with constants used when unpacking some of them - * (5) Internal control methods - * (6) Callbacks and other support for ForkJoinTask methods - * (7) Exported methods - * (8) Static block initializing statics in minimally dependent order - */ - - // Static utilities - - /** - * If there is a security manager, makes sure caller has - * permission to modify threads. - */ - private static void checkPermission() { - SecurityManager security = System.getSecurityManager(); - if (security != null) - security.checkPermission(modifyThreadPermission); - } - - // Nested classes - - /** - * Factory for creating new {@link ForkJoinWorkerThread}s. - * A {@code ForkJoinWorkerThreadFactory} must be defined and used - * for {@code ForkJoinWorkerThread} subclasses that extend base - * functionality or initialize threads with different contexts. - */ - public static interface ForkJoinWorkerThreadFactory { - /** - * Returns a new worker thread operating in the given pool. - * - * @param pool the pool this thread works in - * @throws NullPointerException if the pool is null - * @return the new worker thread - */ - public ForkJoinWorkerThread newThread(ForkJoinPool pool); - } - - /** - * Default ForkJoinWorkerThreadFactory implementation; creates a - * new ForkJoinWorkerThread. - */ - static final class DefaultForkJoinWorkerThreadFactory - implements ForkJoinWorkerThreadFactory { - public final ForkJoinWorkerThread newThread(ForkJoinPool pool) { - return new ForkJoinWorkerThread(pool); - } - } - - /** - * Class for artificial tasks that are used to replace the target - * of local joins if they are removed from an interior queue slot - * in WorkQueue.tryRemoveAndExec.

A {@code ManagedBlocker} provides two methods. Method - * {@code isReleasable} must return {@code true} if blocking is - * not necessary.

Huge numbers of tasks and - * subtasks may be hosted by a small number of actual threads in a - * ForkJoinPool, at the price of some usage limitations. - * - *

A "main" {@code ForkJoinTask} begins execution when it is - * explicitly submitted to a {@link ForkJoinPool}, or, if not already - * engaged in a ForkJoin computation, commenced in the {@link - * ForkJoinPool#commonPool()} via {@link #fork}, {@link #invoke}, or - * related methods. Once started, it will usually in turn start other - * subtasks. As indicated by the name of this class, many programs - * using {@code ForkJoinTask} employ only methods {@link #fork} and - * {@link #join}, or derivatives such as {@link - * #invokeAll(ForkJoinTask...) invokeAll}. However, this class also - * provides a number of other methods that can come into play in - * advanced usages, as well as extension mechanics that allow support - * of new forms of fork/join processing. - * - *

A {@code ForkJoinTask} is a lightweight form of {@link Future}. - * The efficiency of {@code ForkJoinTask}s stems from a set of - * restrictions (that are only partially statically enforceable) - * reflecting their main use as computational tasks calculating pure - * functions or operating on purely isolated objects. The primary - * coordination mechanisms are {@link #fork}, that arranges - * asynchronous execution, and {@link #join}, that doesn't proceed - * until the task's result has been computed. Computations should - * ideally avoid {@code synchronized} methods or blocks, and should - * minimize other blocking synchronization apart from joining other - * tasks or using synchronizers such as Phasers that are advertised to - * cooperate with fork/join scheduling. Subdividable tasks should also - * not perform blocking I/O, and should ideally access variables that - * are completely independent of those accessed by other running - * tasks. These guidelines are loosely enforced by not permitting - * checked exceptions such as {@code IOExceptions} to be - * thrown. However, computations may still encounter unchecked - * exceptions, that are rethrown to callers attempting to join - * them. These exceptions may additionally include {@link - * RejectedExecutionException} stemming from internal resource - * exhaustion, such as failure to allocate internal task - * queues. Rethrown exceptions behave in the same way as regular - * exceptions, but, when possible, contain stack traces (as displayed - * for example using {@code ex.printStackTrace()}) of both the thread - * that initiated the computation as well as the thread actually - * encountering the exception; minimally only the latter. - * - *

It is possible to define and use ForkJoinTasks that may block, - * but doing do requires three further considerations: (1) Completion - * of few if any other tasks should be dependent on a task - * that blocks on external synchronization or I/O. Event-style async - * tasks that are never joined (for example, those subclassing {@link - * CountedCompleter}) often fall into this category. (2) To minimize - * resource impact, tasks should be small; ideally performing only the - * (possibly) blocking action. (3) Unless the {@link - * ForkJoinPool.ManagedBlocker} API is used, or the number of possibly - * blocked tasks is known to be less than the pool's {@link - * ForkJoinPool#getParallelism} level, the pool cannot guarantee that - * enough threads will be available to ensure progress or good - * performance. - * - *

The primary method for awaiting completion and extracting - * results of a task is {@link #join}, but there are several variants: - * The {@link Future#get} methods support interruptible and/or timed - * waits for completion and report results using {@code Future} - * conventions. Method {@link #invoke} is semantically - * equivalent to {@code fork(); join()} but always attempts to begin - * execution in the current thread. The "quiet" forms of - * these methods do not extract results or report exceptions. These - * may be useful when a set of tasks are being executed, and you need - * to delay processing of results or exceptions until all complete. - * Method {@code invokeAll} (available in multiple versions) - * performs the most common form of parallel invocation: forking a set - * of tasks and joining them all. - * - *

In the most typical usages, a fork-join pair act like a call - * (fork) and return (join) from a parallel recursive function. As is - * the case with other forms of recursive calls, returns (joins) - * should be performed innermost-first. For example, {@code a.fork(); - * b.fork(); b.join(); a.join();} is likely to be substantially more - * efficient than joining {@code a} before {@code b}. - * - *

The execution status of tasks may be queried at several levels - * of detail: {@link #isDone} is true if a task completed in any way - * (including the case where a task was cancelled without executing); - * {@link #isCompletedNormally} is true if a task completed without - * cancellation or encountering an exception; {@link #isCancelled} is - * true if the task was cancelled (in which case {@link #getException} - * returns a {@link java.util.concurrent.CancellationException}); and - * {@link #isCompletedAbnormally} is true if a task was either - * cancelled or encountered an exception, in which case {@link - * #getException} will return either the encountered exception or - * {@link java.util.concurrent.CancellationException}. - * - *

The ForkJoinTask class is not usually directly subclassed. - * Instead, you subclass one of the abstract classes that support a - * particular style of fork/join processing, typically {@link - * RecursiveAction} for most computations that do not return results, - * {@link RecursiveTask} for those that do, and {@link - * CountedCompleter} for those in which completed actions trigger - * other actions. Normally, a concrete ForkJoinTask subclass declares - * fields comprising its parameters, established in a constructor, and - * then defines a {@code compute} method that somehow uses the control - * methods supplied by this base class. - * - *

Method {@link #join} and its variants are appropriate for use - * only when completion dependencies are acyclic; that is, the - * parallel computation can be described as a directed acyclic graph - * (DAG). Otherwise, executions may encounter a form of deadlock as - * tasks cyclically wait for each other. However, this framework - * supports other methods and techniques (for example the use of - * {@link Phaser}, {@link #helpQuiesce}, and {@link #complete}) that - * may be of use in constructing custom subclasses for problems that - * are not statically structured as DAGs. To support such usages, a - * ForkJoinTask may be atomically tagged with a {@code short} - * value using {@link #setForkJoinTaskTag} or {@link - * #compareAndSetForkJoinTaskTag} and checked using {@link - * #getForkJoinTaskTag}. The ForkJoinTask implementation does not use - * these {@code protected} methods or tags for any purpose, but they - * may be of use in the construction of specialized subclasses. For - * example, parallel graph traversals can use the supplied methods to - * avoid revisiting nodes/tasks that have already been processed. - * (Method names for tagging are bulky in part to encourage definition - * of methods that reflect their usage patterns.) - * - *

Most base support methods are {@code final}, to prevent - * overriding of implementations that are intrinsically tied to the - * underlying lightweight task scheduling framework. Developers - * creating new basic styles of fork/join processing should minimally - * implement {@code protected} methods {@link #exec}, {@link - * #setRawResult}, and {@link #getRawResult}, while also introducing - * an abstract computational method that can be implemented in its - * subclasses, possibly relying on other {@code protected} methods - * provided by this class. - * - *

ForkJoinTasks should perform relatively small amounts of - * computation. Large tasks should be split into smaller subtasks, - * usually via recursive decomposition. As a very rough rule of thumb, - * a task should perform more than 100 and less than 10000 basic - * computational steps, and should avoid indefinite looping. If tasks - * are too big, then parallelism cannot improve throughput. If too - * small, then memory and internal task maintenance overhead may - * overwhelm processing. - * - *

This class provides {@code adapt} methods for {@link Runnable} - * and {@link Callable}, that may be of use when mixing execution of - * {@code ForkJoinTasks} with other kinds of tasks. When all tasks are - * of this form, consider using a pool constructed in asyncMode. - * - *

ForkJoinTasks are {@code Serializable}, which enables them to be - * used in extensions such as remote execution frameworks. It is - * sensible to serialize tasks only before or after, but not during, - * execution. Serialization is not relied on during execution itself. - * - * @since 1.7 - * @author Doug Lea - */ -@SuppressWarnings("all") -public abstract class ForkJoinTask implements Future, Serializable { - - /* - * See the internal documentation of class ForkJoinPool for a - * general implementation overview.

The table size - * is a power of two. Indexing uses masked per-thread hash codes. - * Nearly all declarations in this class are package-private, - * accessed directly by subclasses. - * - * Table entries are of class Cell; a variant of AtomicLong padded - * to reduce cache contention on most processors. Padding is - * overkill for most Atomics because they are usually irregularly - * scattered in memory and thus don't interfere much with each - * other. But Atomic objects residing in arrays will tend to be - * placed adjacent to each other, and so will most often share - * cache lines (with a huge negative performance impact) without - * this precaution. - * - * In part because Cells are relatively large, we avoid creating - * them until they are needed. When there is no contention, all - * updates are made to the base field. Upon first contention (a - * failed CAS on base update), the table is initialized to size 2. - * The table size is doubled upon further contention until - * reaching the nearest power of two greater than or equal to the - * number of CPUS. Table slots remain empty (null) until they are - * needed. - * - * A single spinlock ("busy") is used for initializing and - * resizing the table, as well as populating slots with new Cells. - * There is no need for a blocking lock; when the lock is not - * available, threads try other slots (or the base). During these - * retries, there is increased contention and reduced locality, - * which is still better than alternatives. - * - * Per-thread hash codes are initialized to random values. - * Contention and/or table collisions are indicated by failed - * CASes when performing an update operation (see method - * retryUpdate). Upon a collision, if the table size is less than - * the capacity, it is doubled in size unless some other thread - * holds the lock. If a hashed slot is empty, and lock is - * available, a new Cell is created. Otherwise, if the slot - * exists, a CAS is tried.
