01e8100496 Prevent any leaks when HttpPostStandardRequestDecoder constructor throws (#9837)
Motivation:

HttpPostStandardRequestDecoder may throw multiple different exceptions in the constructor which could lead to memory leaks. We need to guard against this by explicit catch all of them and rethrow after we released any allocated memory.

Modifications:

- Catch, destroy and rethrow in any case
- Ensure we correctly wrap IllegalArgumentExceptions
- Add unit tests

Result:

Fixes https://github.com/netty/netty/issues/9829

f48d9fa8d0 Bugfix #9673: Origin header is always sent from WebSocket client (#9692)
Those who need 'Origin' or 'Sec-WebSocket-Origin' headers should provide them explicitly, like it is stated in WebSocket specs.

E.g. through custom headers:

    HttpHeaders customHeaders = new DefaultHttpHeaders()
        .add(HttpHeaderNames.ORIGIN, "http://localhost:8080");
    new WebSocketClientProtocolHandler(
        new URI("ws://localhost:1234/test"), WebSocketVersion.V13, subprotocol,
        allowExtensions, customHeaders, maxFramePayloadLength, handshakeTimeoutMillis)

* Remove enforced origin headers.
* Update tests

Fixes #9673: Origin header is always sent from WebSocket client

7ff8cde66f Send close frame on channel close, when this frame was not send manually (#9745)
Motivation:
By default CloseWebSocketFrames are handled automatically.
However I need manually manage their sending both on client- and on server-sides.

Modification:
Send close frame on channel close automatically, when it was not send before explicitly.

Result:
No more messages like "Connection closed by remote peer" for normal close flows.

7df012884f Rename SimpleChannelInboundHandler.channelRead0() to messageReceived() (#8819)
Motivation

Per javadoc in 4.1.x SimpleChannelInboundHandler:

"Please keep in mind that channelRead0(ChannelHandlerContext, I) will be
renamed to messageReceived(ChannelHandlerContext, I) in 5.0."

Modifications

Rename aforementioned method and all references/overrides.

Result

Method is renamed.

db84735975 Simplify WebSocket handlers constructor arguments hell #9698 (#9699)
### Motivation:

Introduction of `WebSocketDecoderConfig` made our server-side code more elegant and simpler for support.

However there is still some problem with maintenance and new features development for WebSocket codecs (`WebSocketServerProtocolHandler`, `WebSocketServerProtocolHandler`).

Particularly, it makes me ~~crying with blood~~ extremely sad to add new parameter and yet another one constructor into these handlers, when I want to contribute new feature.

### Modification:

I've extracted all parameters for client and server WebSocket handlers into config/builder structures, like it was made for decoders in PR #9116.

### Result:

* Fixes #9698: Simplify WebSocket handlers constructor arguments hell
* Unblock further development in this module (configurable close frame handling on server-side; automatic close-frame sending, when missed; memory leaks on protocol violations; etc...)

Bonuses:

* All defaults are gathered in one place and could be easily found/reused.
* New API greatly simplifies usage, but does NOT allow inheritance or modification.
* New API would simplify long-term maintenance of WebSockets module.

### Example

    WebSocketClientProtocolConfig config = WebSocketClientProtocolConfig.newBuilder()
        .webSocketUri("wss://localhost:8443/fx-spot")
        .subprotocol("trading")
        .handshakeTimeoutMillis(15000L)
        .build();
    ctx.pipeline().addLast(new WebSocketClientProtocolHandler(config));

Motivation:

At the moment we miss to poll the method queue when we see an Informational response code. This can lead to out-of-sync of request / response pairs when later try to compare these.

Modifications:

b17371c198 Fix indexOutOfBoundsException when multipart/form-data is incorrect value (#9688)
Motivation:

HttpPostRequestDecoder.splitHeaderContentType() throws a StringIndexOutOfBoundsException when it parses a Content-Type header that starts with a semicolon ;. We should skip the execution for incorrect multipart form data.


Modification:

Protect ChannelHandler from reentrancee issues (#9358)
Motivation:

At the moment it is quite easy to hit reentrance issues when you have multiple handlers in the pipeline and each of the handlers does not correctly protect against these. To make it easier for the user we should try to protect from these. The issue is usually if and inbound event will trigger and outbound event and this outbound event then against triggeres an inbound event. This may result in having methods in a ChannelHandler re-enter some method and so state can be corrupted or messages be re-ordered.

Modifications:

- Keep track of inbound / outbound operations in DefaultChannelHandlerContext and if reentrancy is detected break it by scheduling the action on the EventLoop. This will then be picked up once the method returns and so the reentrancy is broken up.
- Adjust tests which made strange assumptions about execution order

Result:

No more reentrancy of handlers possible.

67b851209f Ensure we replace WebSocketServerProtocolHandshakeHandler before doing the handshake (#9472)
Motivation:

We need to ensure we replace WebSocketServerProtocolHandshakeHandler before doing the actual handshake as the handshake itself may complete directly and so forward pending bytes through the pipeline.

e8c2986cf1 Fix HttpUtil.getCharset to not throw illegal charset exception (#9439)
Motivation:

If the HttpUtil.getCharset method is called with an illegal charset like
"charset=!illegal!" it throws an IllegalCharsetNameException. But the javadoc
states, that defaultCharset is returned if incorrect header value. Since the
client sending the request sets the header value this should not crash.

Modification:

HttpUtil.getCharset catches the IllegalCharsetNameException and returns the
defualt value.

Result:

HttpUtil.getCharset does not throw IllegalCharsetNameException any more.

10ee697557 Allow to turn off Utf8FrameValidator creation for websocket with Bina… (#9417)
…ryWebSocketFrames

Motivation:

`Utf8FrameValidator` is always created and added to the pipeline in `WebSocketServerProtocolHandler.handlerAdded` method. However, for websocket connection with only `BinaryWebSocketFrame`'s UTF8 validator is unnecessary overhead. Adding of `Utf8FrameValidator` could be easily avoided by extending of `WebSocketDecoderConfig` with additional property.

Specification requires UTF-8 validation only for `TextWebSocketFrame`.

Modification:

Added `boolean WebSocketDecoderConfig.withUTF8Validator` that allows to avoid adding of `Utf8FrameValidator` during pipeline initialization.

Result:

Less overhead when using only `BinaryWebSocketFrame`within web socket.

e4995be33c Use allocator when constructing ByteBufHolder sub-types or use Unpool… (#9377)
Motivation:

In many places Netty uses Unpooled.buffer(0) while should use EMPTY_BUFFER. We can't change this due to back compatibility in the constructors but can use Unpooled.EMPTY_BUFFER in some cases to ensure we not allocate at all. In others we can directly use the allocator either from the Channel / ChannelHandlerContext or the request / response.

Modification:

- Use Unpooled.EMPTY_BUFFER where possible
- Use allocator where possible

2d72a7c561 Preserve the original filename when encoding a multipart/form in mixed mode. (#9270)
Motivation:

The HttpPostRequestEncoder overwrites the original filename of file uploads sharing the same name encoded in mixed mode when it rewrites the multipart body header of the previous file. The original filename should be preserved instead.

Modifications:

Change the HttpPostRequestEncoder to reuse the correct filename when the encoder switches to mixed mode. The original test is incorrect and has been modified too, in addition it tests with an extra file upload since the current test was not testing the continuation of a mixed mode.

Result:

The HttpPostRequestEncoder will preserve the original filename of the first fileupload when switching to mixed mode

d9db218291 WebSocket is closed without an error on protocol violations (#9116)
Motivation:

Incorrect WebSockets closure affects our production system.
Enforced 'close socket on any protocol violation' prevents our custom termination sequence from execution.
Huge number of parameters is a nightmare both in usage and in support (decoders configuration).

Modification:

- Fix violations handling - send proper response codes.
- Fix for messages leak.
- Introduce decoder's option to disable default behavior (send close frame) on protocol violations.
- Encapsulate WebSocket response codes - WebSocketCloseStatus.
- Encapsulate decoder's configuration into a separate class - WebSocketDecoderConfig.

Result:

Fixes #8295.

576b1768f4 Introduce WebSocketClientHandshaker::absoluteUpgradeUrl, close #9205 (#9206)
Motivation:

When connecting through an HTTP proxy over clear HTTP, user agents must send requests with an absolute url. This hold true for WebSocket Upgrade request.

WebSocketClientHandshaker and subclasses currently always send requests with a relative url, which causes proxies to crash as request is malformed.

Modification:

Introduce a new parameter `absoluteUpgradeUrl` and expose it in constructors and WebSocketClientHandshakerFactory.

Result:

It's now possible to configure WebSocketClientHandshaker so it works properly with HTTP proxies over clear HTTP.

1465e3ce06 Support handshake timeout in websocket handlers (#8856)
Motivation:

Support handshake timeout option in websocket handlers. It makes sense to limit the time we need to move from `HANDSHAKE_ISSUED` to `HANDSHAKE_COMPLETE` states when upgrading to WebSockets

Modification:

- Add `handshakeTimeoutMillis` option in `WebSocketClientProtocolHandshakeHandler`  and `WebSocketServerProtocolHandshakeHandler`.
- Schedule a timeout task, the task will trigger user event `HANDSHAKE_TIMEOUT` if the handshake timed out.

23554e6997 Ensure "full" ownership of msgs passed to EmbeddedChannel.writeInbound() (#9058)
Motivation

Pipeline handlers are free to "take control" of input buffers if they have singular refcount - in particular to mutate their raw data if non-readonly via discarding of read bytes, etc.

However there are various places (primarily unit tests) where a wrapped byte-array buffer is passed in and the wrapped array is assumed not to change (used after the wrapped buffer is passed to EmbeddedChannel.writeInbound()). This invalid assumption could result in unexpected errors, such as those exposed by #8931.

Modifications

Anywhere that the data passed to writeInbound() might be used again, ensure that either:
- A copy is used rather than wrapping a shared byte array, or
- The buffer is otherwise protected from modification by making it read-only

For the tests, copying is preferred since it still allows the "mutating" optimizations to be exercised.

Results

Avoid possible errors when pipeline assumes it has full control of input buffer.

a57f73e1fe WebSocket client handshaker to support "force close" after timeout (#8896)
Motivation:

RFC 6455 defines that, generally, a WebSocket client should not close a TCP
connection as far as a server is the one who's responsible for doing that.
In practice tho', it's not always possible to control the server. Server's
misbehavior may lead to connections being leaked (if the server does not
comply with the RFC).

RFC 6455 #7.1.1 says

> In abnormal cases (such as not having received a TCP Close from the server
after a reasonable amount of time) a client MAY initiate the TCP Close.

Modifications:

* WebSocket client handshaker additional param `forceCloseAfterMillis`

* Use 10 seconds as default

Result:

WebSocket client handshaker to comply with RFC. Fixes #8883.

a44c33136f Fix HttpUtil.isKeepAlive to behave correctly when Connection is a comma separated list (#8924)
Motivation:

According to the specification, the "Connection" header's syntax is:

"
The Connection header field's value has the following grammar:

     Connection        = 1#connection-option
     connection-option = token

Connection options are case-insensitive.
"
https://tools.ietf.org/html/rfc7230#section-6.1

This means that Connection's value can have at least one element or
a comma separated list with elements
When calculating whether the connection can remain open,
HttpUtil.isKeepAlive(HttpMessage) should take this into account.

Modifications:

- Check for "close" and "keep-alive" in a comma separated list
- Add unit test

Result:

HttpUtil.isKeepAlive(HttpMessage) works correctly when "Connection: Upgrade, close"

Deprecate ChannelInboundHandlerAdapter and ChannelOutboundHandlerAdapter (#8929)
Motivation:

As we now us java8 as minimum java version we can deprecate ChannelInboundHandlerAdapter / ChannelOutboundHandlerAdapter and just move the default implementations into the interfaces. This makes things a bit more flexible for the end-user and also simplifies the class-hierarchy.

Modifications:

- Mark ChannelInboundHandlerAdapter and ChannelOutboundHandlerAdapter as deprecated
- Add default implementations to ChannelInboundHandler / ChannelOutboundHandler
- Refactor our code to not use ChannelInboundHandlerAdapter / ChannelOutboundHandlerAdapter anymore

Result:

Cleanup class-hierarchy and make things a bit more flexible.

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`.

Use ThreadLocalRandom.current().nextInt() directly instead of (int) ThreadLocalRandom.current().nextDouble()

Result:

Less custom code to maintain

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.

Result

Fixes #8772
