d036b24a4b Do not depend on the implementation detail of Unpooled.buffer(int) when accessing backing array. (#8865)
Motivation:

We should not depend on the implementation detail of Unpooled.buffer(int) to allocate the exact size of backing byte[] as depending on the implementation it may return a buffer with a bigger backing array.

Modifications:

Explicit allocate the byte[] and wrap it in the ByteBuf. This way we are sure that ByteBuf.array() returns an byte[] which has the exact length and content we expect.

Result:

More correct and safe usage of ByteBuf.array()

1bc7c4900c Handle null "origin" header in "Old Hixie 75 handshake" as proper bad request. (#8864)
Motivation:

Gracefully respond on bad client request.
We have a set of errors produced by Android 7.1.1/7.1.2 clients where both headers `HttpHeaderNames.SEC_WEBSOCKET_VERSION` and `HttpHeaderNames.ORIGIN` are not present. Absence of the first headers leads to WebSocketServerHandshaker00 be applied as a handshaker. However, null 2nd header causes

```
java.lang.NullPointerException: value
 io.netty.util.internal.ObjectUtil.checkNotNull(ObjectUtil.java:33)
 io.netty.handler.codec.DefaultHeaders.addObject(DefaultHeaders.java:327)
 io.netty.handler.codec.http.DefaultHttpHeaders.add(DefaultHttpHeaders.java:123)
 io.netty.handler.codec.http.websocketx.WebSocketServerHandshaker00.newHandshakeResponse(WebSocketServerHandshaker00.java:162)
```
Which causes connection close with unclear reason.

Modification:

Added null-check, and in case of null an appropriate WebSocketHandshakeException is thrown.

Result:

In case of null `HttpHeaderNames.ORIGIN` header a WebSocketHandshakeException is caught by WebSocketServerProtocolHandler which sends a graceful `BAD_REQUEST`.

900d00d5db Java 8 migration. Move WebSocketUtil.base64 to java version instead of netty (#8837)
Motivation:

Since Java 8, JDK has `java.util.Base64` that could replace custom netty implementation. It is faster (3x for this particular PR) and simpler.

Modifications:

Use Base64 directly.


Result:

dd96b4a876 Fix h2c upgrade failure when multiple connection headers are present in upgrade request (#8848)
Motivation:

When more than one connection header is present in h2c upgrade request, upgrade fails. This is to fix that.

Modification:
In HttpServerUpgradeHandler's upgrade() method, check whether any of the connection header value is upgrade, not just the first header value which might return a different value other than upgrade.

Result:
Fixes #8846.

With this PR, now when multiple connection headers are sent with the upgrade request, upgrade will not fail.

cfa60552fb Selective Message Aggregation (#8793)
Motivation

Implementations of MessageAggregator (HttpObjectAggregator in particular) may wish to
selectively aggrerage requests and responses on a case-by-case basis such as for example
only POST requests or only responses of a certain content-type.

Modifications

Adding a flag to MessageAggregator that toggles between true/false depending on if aggregation
is desired for the current message or not.

b7ceeb1797 Compare HttpMethod by reference (#8815)
Motivation:

In most cases, HttpMethod instance is built from the factory method and the same instance is taken for known Http Methods. So we can implement fast path for equals().

Modification:

Replace == checks with HttpMethod.equals;
Use this == o within HttpMethod.equals;
Replaced known new HttpMethod with HttpMethod.valueOf;
Result:

Comparisons should be a bit faster in some cases.

Decouple EventLoop details from the IO handling for each transport to… (#8680)
* Decouble EventLoop details from the IO handling for each transport to allow easy re-use of code and customization

Motiviation:

As today extending EventLoop implementations to add custom logic / metrics / instrumentations is only possible in a very limited way if at all. This is due the fact that most implementations are final or even package-private. That said even if these would be public there are the ability to do something useful with these is very limited as the IO processing and task processing are very tightly coupled. All of the mentioned things are a big pain point in netty 4.x and need improvement.

Modifications:

This changeset decoubled the IO processing logic from the task processing logic for the main transport (NIO, Epoll, KQueue) by introducing the concept of an IoHandler. The IoHandler itself is responsible to wait for IO readiness and process these IO events. The execution of the IoHandler itself is done by the SingleThreadEventLoop as part of its EventLoop processing. This allows to use the same EventLoopGroup (MultiThreadEventLoupGroup) for all the mentioned transports by just specify a different IoHandlerFactory during construction.

Beside this core API change this changeset also allows to easily extend SingleThreadEventExecutor / SingleThreadEventLoop to add custom logic to it which then can be reused by all the transports. The ideas are very similar to what is provided by ScheduledThreadPoolExecutor (that is part of the JDK). This allows for example things like:

  * Adding instrumentation / metrics:
    * how many Channels are registered on an SingleThreadEventLoop
    * how many Channels were handled during the IO processing in an EventLoop run
    * how many task were handled during the last EventLoop / EventExecutor run
    * how many outstanding tasks we have
    ...
    ...
  * Implementing custom strategies for choosing the next EventExecutor / EventLoop to use based on these metrics.
  * Use different Promise / Future / ScheduledFuture implementations
  * decorate Runnable / Callables when submitted to the EventExecutor / EventLoop

As a lot of functionalities are folded into the MultiThreadEventLoopGroup and SingleThreadEventLoopGroup this changeset also removes:

  * AbstractEventLoop
  * AbstractEventLoopGroup
  * EventExecutorChooser
  * EventExecutorChooserFactory
  * DefaultEventLoopGroup
  * DefaultEventExecutor
  * DefaultEventExecutorGroup

Result:

Fixes https://github.com/netty/netty/issues/8514 .

Tighten contract between Channel and EventLoop by require the EventLoop on Channel construction. (#8587)
Motivation:

At the moment it’s possible to have a Channel in Netty that is not registered / assigned to an EventLoop until register(...) is called. This is suboptimal as if the Channel is not registered it is also not possible to do anything useful with a ChannelFuture that belongs to the Channel. We should think about if we should have the EventLoop as a constructor argument of a Channel and have the register / deregister method only have the effect of add a Channel to KQueue/Epoll/... It is also currently possible to deregister a Channel from one EventLoop and register it with another EventLoop. This operation defeats the threading model assumptions that are wide spread in Netty, and requires careful user level coordination to pull off without any concurrency issues. It is not a commonly used feature in practice, may be better handled by other means (e.g. client side load balancing), and therefore we propose removing this feature.

Modifications:

- Change all Channel implementations to require an EventLoop for construction ( + an EventLoopGroup for all ServerChannel implementations)
- Remove all register(...) methods from EventLoopGroup
- Add ChannelOutboundInvoker.register(...) which now basically means we want to register on the EventLoop for IO.
- Change ChannelUnsafe.register(...) to not take an EventLoop as parameter (as the EventLoop is supplied on custruction).
- Change ChannelFactory to take an EventLoop to create new Channels and introduce ServerChannelFactory which takes an EventLoop and one EventLoopGroup to create new ServerChannel instances.
- Add ServerChannel.childEventLoopGroup()
- Ensure all operations on the accepted Channel is done in the EventLoop of the Channel in ServerBootstrap
- Change unit tests for new behaviour

Result:

A Channel always has an EventLoop assigned which will never change during its life-time. This ensures we are always be able to call any operation on the Channel once constructed (unit the EventLoop is shutdown). This also simplifies the logic in DefaultChannelPipeline a lot as we can always call handlerAdded / handlerRemoved directly without the need to wait for register() to happen.

Also note that its still possible to deregister a Channel and register it again. It's just not possible anymore to move from one EventLoop to another (which was not really safe anyway).

9ed2884d3a Support 1012, 1013 and 1014 WebSocket close status code (#8664)
Motivation:

RFC 6455 doesn't define close status codes 1012, 1013 and 1014.
Yet, since then, IANA has defined them and web browsers support them.

From https://www.iana.org/assignments/websocket/websocket.xhtml:

* 1012: Service Restart
* 1013: Try Again Later
* 1014: The server was acting as a gateway or proxy and received an invalid response from the upstream server. This is similar to 502 HTTP Status Code.

Modification:

Make status codes 1012, 1013 and 1014 legit.

Result:

WebSocket status codes as defined by IANA are supported.

Remove support for marking reader and writerIndex in ByteBuf to reduce overhead and complexity. (#8636)
Motivation:

ByteBuf supports “marker indexes”. The intended use case for these is if a speculative operation (e.g. decode) is in process the user can “mark” and interface and refer to it later if the operation isn’t successful (e.g. not enough data). However this is rarely used in practice,
requires extra memory to maintain, and introduces complexity in the state management for derived/pooled buffer initialization, resizing, and other operations which may modify reader/writer indexes.

Modifications:

Remove support for marking and adjust testcases / code.

Result:

Fixes https://github.com/netty/netty/issues/8535.

a6f807dd68 Fix context and window sizes sides. (#8395)
Motivation:

As mentioned in RFC 7692 :

The "server_no_context_takeover" Extension Parameter should be used on server side for compression and on client side for decompression.

The "client_no_context_takeover" Extension Parameter should be used on client side for compression and on server side for decompression.

Right now, in PerMessageDeflateClientExtensionHandshaker, the decoder uses clientNoContext instead of serverNoContext and the encoder uses serverNoContext instead of clientNoContext.

The same inversion is present in PerMessageDeflateServerExtensionHandshaker: the decoder uses
serverNoContext instead of clientNoContext, while the encoder uses serverNoContext instead of clientNoContext. Besides the context inversion, the sliding window sizes seem to be inversed as well.

Modification:

Inverse clientNoContext with serverNoContext and clientWindowSize with serverWindowSize for both the Decoder and Encoder in PerMessageDeflateServerExtensionHandshaker and PerMessageDeflateClientExtensionHandshaker.

Result:

This fixes the decompression fail in the case that one of the contexts is set and the other one is not.

See also https://shipilev.net/blog/2016/arrays-wisdom-ancients/#_conclusion.

Modifications:

Replace toArray(new T[size]) with toArray(new T[0]).

Result:

Faster code.

fa4e28ba1c Fix random number generators in WebSocketUtil
Motivation:

Implementation of WebSocketUtil/randomNumber is incorrect and might violate
the API returning values > maximum specified.

Modifications:

* WebSocketUtil/randomNumber is reimplemented, the idea of the solution described
  in the comment in the code

* Implementation of WebSocketUtil/randomBytes changed to nextBytes method

* PlatformDependet.threadLocalRandom is used instead of Math.random to improve efficiency

* Added test cases to check random numbers generator

* To ensure corretness, we now assert that min < max when generating random number

Result:

WebSocketUtil/randomNumber always produces correct result.

4c709be1ab Print correct invalid character after unwrapping value in CookieEncoder
Motivation:

If a wrapped cookie value with an invalid charcater is passed to the strict
encoder, an exception is thrown on validation but the error message contains
a character at the wrong position.

Modifications:

Print `unwrappedValue.charAt(pos)` instead of `value.charAt(pos)`.

Result:

The exception indicates the correct invalid character in the unwrapped cookie.

6208c9b0d6 Mention the HttpObjectEncoder's state in the message of the IllegalStateException (#7996)
Motivation

The HttpObjectEncoder raises an IllegalStateException due to an illegal state but doesn't mention what the state was. It could be useful for debugging purposes to figure out what happened.

Modifications

Mention the HttpObjectEncoder's state in the message of the IllegalStateException.

Result

An exception with more information what caused it.

48911e0b63 Set (and override) websocket handshake headers after custom headers (#7975)
Motivation:

Currently, when passing custom headers to a WebSocketClientHandshaker,
if values are added for headers that are reserved for use in the
websocket handshake performed with the server, these custom values can
be used by the server to compute the websocket handshake challenge. If
the server computes the response to the challenge with the custom header
values, rather than the values computed by the client handshaker, the
handshake may fail.

Modifications:

Update the client handshaker implementations to add the custom header
values first, and then set the reserved websocket header values.

Result:

Reserved websocket handshake headers, if present in the custom headers
passed to the client handshaker, will not be propagated to the server.
Instead the client handshaker will propagate the values it generates.

Fixes #7973.

9a3311506e Run the WebSocketClientHandshaker08Test on the 08 implementation (#7974)
Motivation:

The websockets abstract test suite does not run against the 08
implementation in the 08 version of the test suite.

Modifications:

Update the WebSocketClientHandshaker08Test to instantiate a new
WebSocketClientHandshaker08 rather than an 07 handshaker.

Result:

The WebSocketClientHandshaker08Test now tests the 08 implementation.

19d1f4ea62 Propagate pong frames in WebSocketProtocolHandler (#7955)
Motivation:

Currently, on recipt of a PongWebSocketFrame, the
WebSocketProtocolHandler will drop the frame, rather than passing it
along so it can be referenced by other handlers.

Modifications:

Add boolean field to WebSocketProtocolHandler to indicate whether Pong
frames should be dropped or propagated, defaulting to "true" to preserve
existing functionality.

Add new constructors to the client and server implementations of
WebSocketProtocolHandler that allow for overriding the behavior for the
handling of Pong frames.

Result:

PongWebSocketFrames are passed along the channel, if specified.

f874a37ecb Fixes NPE in Corshandler for unauthorized prefligt requests (#7865)
Motivation:
NPE in `CorsHandler` if a pre-flight request is done using an Origin header which is not allowed by any `CorsConfig` passed to the handler on creation.

Modifications:
During the pre-flight, check the `CorsConfig` for `null` and handle it correctly by not returning any access-control header

Result:
No more NPE for pre-flight requests with unauthorized origins.

Motivation:

Finer granularity when configuring CorsHandler, enabling different policies for different origins.

Modifications:

Result:

The changes don't break backwards compatibility. The extra ctor can be used to provide more than one CorsConfig object.

CorsHandler.write(...) should not cause a flush. (#7839)
Motivation:

Unnecessary flushes reduce the amount of flush coalescing that can happen at higher levels and thus can increase number of packets (because of TCP_NODELAY) and lower throughput (due to syscalls, TLS frames, etc)

Modifications:

Replace writeAndFlush(...) with write(...)

Result:

741602050f Don't replace all 'connection' headers when sending h2c upgrade request (#7824)
Motivation:

There may be meaningful 'connection' headers that exist on a request
that is used to attempt a HTTP/1.x upgrade request that will be
clobbered.

Modifications:

HttpClientUpgradeHandler uses the `HttpHeaders.add` instead of
`HttpHeaders.set` when adding the 'upgrade' field.

Result:

Fixes #7823, existing 'connection' headers are preserved.

b309271e49 HttpServerUpgradeHandler shouldn't wait for flush to reshape pipeline
Motivation:

There is a race between both flushing the upgrade response and receiving
more data before the flush ChannelPromise can fire and reshape the
pipeline. Since We have already committed to an upgrade by writing the
upgrade response, we need to be immediately prepared for handling the
next protocol.

Modifications:

The pipeline reshaping logic in HttpServerUpgradeHandler has been moved
out of the ChannelFutureListener attached to the write of the upgrade
response and happens immediately after the writeAndFlush call, but
before the method returns.

Result:

The pipeline is no longer subject to receiving more data before the
pipeline has been reformed.

d60cd0231d HttpProxyHandler generates invalid CONNECT url and Host header when address is resolved
Motivation:

HttpProxyHandler uses `NetUtil#toSocketAddressString` to compute
CONNECT url and Host header.

The url is correct when the address is unresolved, as
`NetUtil#toSocketAddressString` will then use
`getHoststring`/`getHostname`. If the address is already resolved, the
url will be based on the IP instead of the hostname.

There’s an additional minor issue with the Host header: default port
443 should be omitted.

Modifications:

* Introduce NetUtil#getHostname
* Introduce HttpUtil#formatHostnameForHttp to format an
InetSocketAddress to
HTTP format
* Change url computation to favor hostname instead of IP
* Introduce HttpProxyHandler ignoreDefaultPortsInConnectHostHeader
parameter to ignore 80 and 443 ports in Host header

Result:

HttpProxyHandler performs properly when connecting to a resolved address

b640797de1 Fix HttpPostMultipartRequestDecoder.splitMultipartHeader() String index out of range: -1 with empty header
Motivation:

A Malformed empty header value (e.g. Content-Type: \r\n) will trigger a String index out of range
while trying to parse the multi-part request, using the HttpPostMultipartRequestDecoder.

Modification:

Ensure that the substring() method is called passing the endValue >= valueStart.
In case of an empty header value, the empty header value associated with the header key will be returned.

Result:

Fixes #7620

HttpResponseStatus object allocation reduction
Motivation:
Usages of HttpResponseStatus may result in more object allocation then necessary due to not looking for cached objects and the AsciiString parsing method not being used due to CharSequence method being used instead.

Modifications:
- HttpResponseDecoder should attempt to get the HttpResponseStatus from cache instead of allocating a new object
- HttpResponseStatus#parseLine(CharSequence) should check if the type is AsciiString and redirect to the AsciiString parsing method which may not require an additional toString call
- HttpResponseStatus#parseLine(AsciiString) can be optimized and doesn't require and may not require object allocation

Result:
Less allocations when dealing with HttpResponseStatus.

2b4f667791 Fix DefaultHttpDataFactory cleanup bug
Motivation:

DefaultHttpDataFactory uses HttpRequest as map keys.

Because of the implementation of "hashCode"" and "equals" in DefaultHttpRequest,
if we use normal maps, HttpDatas of different requests may end up in the same map entry,
causing cleanup bug.

Consider this example:
- Suppose that request1 is equal to request2, causing their HttpDatas to be stored in one single map entry.
- request1 is cleaned up first, while request2 is still being decoded.
- Consequently request2's HttpDatas are suddenly gone, causing NPE, or worse loss of data.

This bug can be reproduced by starting the HttpUploadServer example,
then run this command:
ab -T 'application/x-www-form-urlencoded' -n 100 -c 5 -p post.txt http://localhost:8080/form

post.txt file content:
a=1&b=2

There will be errors like this:
