dd54c06e1e Close connection for CorruptedFrameException (#8705)
Motivation:

The CorruptedFrameException from the finish() method of the Utf8Validator gets propagated to other handlers while the connection is still open.

Modification:

Override exceptionCaught method of the Utf8FrameValidator and close the connection if it is a CorruptedFrameException.

Result:

The CorruptedFrameException gets propagated to other handlers only after properly closing the connection.

7988cfec0a Correctly propagate write failures from ChunkedWriteHandler (#8716)
Motivation:

ChunkedWriteHandler should report write operation as failed
in case *any* chunked was not written. Right now this is not
true for the last chunk.

Modifications:

* Check if the appropriate write operation was succesfull when
  reporting the last chunk

* Skip writing chunks if the write operation was already marked
  as "done"

* Test cases to cover write failures when dealing with chunked input

Result:

Fix https://github.com/netty/netty/issues/8700

165912365a Clenaup: simplify EpollEventLoop.closeAll() (#8719)
Motivation:

Avoid unnecessary iteration and `ArrayList` allocation.

Modification:

```
for (AbstractEpollChannel channel: channels.values()) {
     array.add(channel);
}
```
replaced with 

`array.addAll(channels.values())`

and

```
Collection<AbstractEpollChannel> array = new ArrayList<AbstractEpollChannel>(channels.size());
array.addAll(channels.values())
```

replaced with:

`AbstractEpollChannel[] localChannels = channels.values().toArray(new AbstractEpollChannel[0]);`

Result:

Simpler code in `EpollEventLoop.closeAll();`

Access the Constructor of the Channel in the constructor of ReflectiveChannelFactory. (#8718)
Motivation:

We should access the Constructor of the passed in class in the Constructor of ReflectiveChannelFactory only to reduce the overhead but also fail-fast.

4ac5264f0e Remove unnecessary loop variable from AsciiString. (#8711)
Motivation:

Incrementing two variables in sync is not necessary when only one will do.

Modifications:

- Remove `j` from `for` loop and replace with `i`.
- Add more unit testing scenarios to cover changed code.

Results:

Unnecessary variable removed.

1b9cdc1f63 Updating ByteBuf Javadocs to represent actual behaviour. (#8709)
Motivation:

The javadocs stating `IndexOutOfBoundsException` is thrown were
different from what `ByteBuf` actually did. We want to ensure the
Javadocs represent reality.

Modifications:

Updated javadocs on `write*`, `ensureWriteable`, `capacity`, and
`maxCapacity` methods.

Results:

Javadocs more closely match actual behaviour.

Correctly buffer multiple outbound streams if needed. (#8694)
Motivation:

In Http2FrameCodec we made the incorrect assumption that we can only have 1 buffered outboundstream as maximum. This is not correct and we need to account for multiple buffered streams.

Modifications:

- Use a map to allow buffer multiple streams
- Add unit test.

Result:

Fixes https://github.com/netty/netty/issues/8692.

Only call handlerRemoved(...) if handlerAdded(...) was called during adding the handler to the pipeline. (#8684)
Motivation:

Due a race in DefaultChannelPipeline / AbstractChannelHandlerContext it was possible to have only handlerRemoved(...) called during tearing down the pipeline, even when handlerAdded(...) was never called. We need to ensure we either call both of none to guarantee a proper lifecycle of the handler.

Modifications:

- Enforce handlerAdded(...) / handlerRemoved(...) semantics / ordering
- Add unit test.

Result:

Fixes https://github.com/netty/netty/issues/8676 / https://github.com/netty/netty/issues/6536 .

Correctly detect and handle CNAME loops. (#8691)
Motivation:

We do not correctly detect loops when follow CNAMEs and so may try to follow it without any success.

Modifications:

- Correctly detect CNAME loops
- Do not cache CNAME entries which point to itself
- Add unit test.

Result:

Fixes https://github.com/netty/netty/issues/8687.

fa84e2b3af Cleanup HTTP/2 tests for Http2FrameCodec and Http2MultiplexCodec (#8646)
Motiviation:

Http2FrameCodecTest and Http2MultiplexCodecTest were quite fragile and often not went through the whole pipeline which made testing sometimes hard and error-prone.

Modification:

- Refactor tests to have data flow through the whole pipeline and so made the test more robust (by testing the while implementation).

Result:

Easier to write tests for the codecs in the future and more robust testing in general.

Beside this it also fixes https://github.com/netty/netty/issues/6036.

66ccd1483a Publicize default explicitFlushAfterFlushes count. (#8683)
Motivation:

Users who want to construct a `FlushConsolidationHandler` with a default `explicitFlushAfterFlushes` but non-default `consolidateWhenNoReadInProgress` may benefit from having an easy way to get the default "flush after flushes" count.

Modifications:

- Moved default `explicitFlushAfterFlushes` value to a public constant.
- Adjusted Javadoc accordingly.

Result:

Default `explicitFlushAfterFlushes` is accessible to callers.

Call FastThreadLocal.removeAll() before notify termination future of … (#8666)
Motivation:

We should try removing all FastThreadLocals for the Thread before we notify the termination. future. The user may block on the future and once it unblocks the JVM may terminate and start unloading classes.

Modifications:

Remove all FastThreadLocals for the Thread before notify termination future.

Result:

e2d9665707 Added comments to LineBasedFrameDecoder, JsonObjectDecoder and XmlFrameDecoder that they are only compatible with UTF-8 encoded streams. (#8651)
Motivation:

LineBasedFrameDecoder, JsonObjectDecoder and XmlFrameDecoder upon investigation of the
sourcecode appeared to only support ASCII or UTF-8 input. It is an important characteristic
and ont reflected in any documentation. This could lead to improper usage and bugs.

Modifications:

Javadoc comment is addedd to all three classes to state that implementation is only
compatible with UTF-8 or ASCII input streams and brifly touches on implementaion details.

Result:

The end user of the netty library would not have to study sorcecode to deterime character
encoding limitations for given classes.

Add test for correctly handling SSLSessionBindingEvent when acting on th… (#8649)
Motivation:

During some other work I noticed we do not have any tests to ensure we correctly use SSLSessionBindingEvent. We should add some testing.

Modifications:

- Added unit test to verify we correctly implement it.
- Ignore the test when using Conscrypt as it not correctly implements it.

Result:

More tests for custom SSL impl.

Fix ClassCastException and native crash when using kqueue transport. (#8665)
Motivation:

How we did the mapping from native code to AbstractKQueueChannel was not safe and could lead to heap corruption. This then sometimes produced ClassCastExceptions or could also lead to crashes. This happened sometimes when running the testsuite.

Modifications:

Use a Map for the mapping (just as we do in the native epoll transport).

Result:

No more heap corruption / crashes.

302dac8c45 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.

db6d94f82a Support 1012, 1013 and 1014 WebSocket status code
Motivation:

RFC 6455 doesn't define status codes 1012, 1013 and 1014.
Yet, since then, IANA has defined them, web browsers support them, applications in the wild do use them but it's currently not possible to buid a Netty based client for those services.

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.

Explict always call ctx.read() when AUTO_READ is false and HTTP/2 is used. (#8647)
Motivation:

We should always call ctx.read() even when AUTO_READ is false as flow-control is enforced by the HTTP/2 protocol.

See also https://tools.ietf.org/html/rfc7540#section-5.2.2.

We already did this before but not explicit and only did so because of some implementation details of ByteToMessageDecoder. It's better to be explicit here to not risk of breakage later on.

Modifications:

- Ensure we always call ctx.read() when AUTO_READ is false
- Add unit test.

Result:

No risk of staling the connection when HTTP/2 is used.

SSLSession.putValue / getValue / removeValue / getValueNames must be thread-safe. (#8648)
Motivation:

SSLSession.putValue / getValue / removeValue / getValueNames must be thread-safe as it may be called from multiple threads. This is also the case in the OpenJDK implementation.

Modifications:

Guard with synchronized (this) blocks to keep the memory overhead low as we do not expect to have these called frequently.

Result:

SSLSession implementation is thread-safe.

ChannelInitializer may be invoked multiple times when used with custom EventExecutor. (#8620)
Motivation:

The ChannelInitializer may be invoked multipled times when used with a custom EventExecutor as removal operation may be done asynchronously. We need to guard against this.

Modifications:

- Change Map to Set which is more correct in terms of how we use it.
- Ensure we only modify the internal Set when the handler was removed yet
- Add unit test.

Respect ctx.read() calls while processing reads for the child channels when using the Http2MultiplexCodec. (#8617)
Motivation:

We did not correct respect ctx.read() calls while processing a read for a child Channel. This could lead to read stales when auto read is disabled and no other read was requested.

Modifications:

- Keep track of extra read() calls while processing reads
- Add unit tests that verify that read() is respected when triggered either in channelRead(...) or channelReadComplete(...)

Result:

d0d30f1fbe Loosen bounds check on CompositeByteBuf's maxNumComponents (#8621)
Motivation:

In versions of Netty prior to 4.1.31.Final, a CompositeByteBuf could be
created with any size (including potentially nonsensical negative
values). This behavior changed in e7737b993, which introduced a bounds
check to only allow for a component size greater than one. This broke
some existing use cases that attempted to create a byte buf with a
single component.

Modifications:

Lower the bounds check on numComponents to include the single component
case, but still throw an exception for anything less than one.

Add unit tests for the case of numComponents being less than, equal to,
and greater than this lower bound.

Result:

Return to the behavior of 4.1.30.Final, allowing one component, but
still include an explicit check against a lower bound.

Note that while creating a CompositeByteBuf with a single component is
in some ways a contradiction of the term "composite", this patch caters
for existing uses while excluding the clearly nonsensical case of asking
for a CompositeByteBuf with zero or fewer components.

Fixes #8613.

a0c3081d82 Reduce http2 buffer slicing (#8598)
Motivation

DefaultHttp2FrameReader currently does a fair amount of "intermediate"
slicing which can be avoided.

Modifications

Avoid slicing the input buffer in DefaultHttp2FrameReader until
necessary. In one instance this also means retainedSlice can be used
instead (which may also avoid allocating).

Results

Less allocations when using http2.
