Do not schedule notify task if there are no listeners attached to the promise. (#8797)
Motivation:

If there are no listeners attached to the promise when full-filling it we do not need to schedule a task to notify.

Modifications:

- Don't schedule a task if there is nothing to notify.
- Add unit tests.

Result:

Fixes https://github.com/netty/netty/issues/8795.

ff7484864b 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.

Fix AppendableCharSequence.subSequence(...) where start == end. (#8798)
Motivation:

To conform to the CharSequence interface we need to return an empty CharSequence when start == end index and a subSequence is requested.

Modifications:

- Correctly handle the case where start == end
- Add unit test

Result:

Fix https://github.com/netty/netty/issues/8796.

Minimize memory footprint for AbstractChannelHandlerContext for handlers that execute in the EventExecutor. (#8786)
Motivation:

We cache the Runnable for some tasks to reduce GC pressure in 4 different fields. This gives overhead in terms of memory usage in all cases, even if we always execute in the EventExecutor (which is the case most of the times).

Modifications:

Move the 4 fields to another class and only have one reference to this in AbstractChannelHandlerContext. This gives a small overhead in the case of execution that is done outside of the EventExecutor but reduce memory footprint in the more likily execution case.

Result:

Less memory used per AbstractChannelHandlerContext in most cases.

1d5b7be3a7 Fix three bugs in CompositeByteBuf (#8773)
Motivation

In #8758, @doom369 reported an infinite loop bug in CompositeByteBuf
which was introduced in #8437.

This is the same small fix for that, along with fixes for two other bugs
found while re-inspecting the changes and adding unit tests.

Modification

- Replace recursive call to toComponentIndex with toComponentIndex0 as
intended
- Add missed "lastAccessed" racy cache invalidation in capacity(int)
method
- Fix incorrect determination of initial offset in non-zero cIndex case
of updateComponentOffsets method
- New unit tests for previously uncovered methods

Results

Fewer bugs.

Release message when validation of passed in ChannelPromise fails when calling write(...) / writeAndFlush(...) (#8769)
Motivation:

We need to release the message when we throw an IllegalArgumentException because of a validation failure of the promise to eliminate the risk of a memory leak.

Modifications:

- Consistently release the message before rethrow
- Add testcase.

Result:

Fixes https://github.com/netty/netty/issues/8765.

0431368621 HttpUtil#is100ContinueExpected clean up (#8740)
Motivation:

Current implementation extract header value as String. We have an idiomatic way for checking presence of a header value.

Modification:

Use HttpHeaders#contains for checking if if contains Expect: 100-continue.

Result:

Use idiomatic way + simplify boolean logic.

Fix flaky ChannelInitializerTest.testChannelInitializerEventExecutor() (#8738)
Motivation:

testChannelInitializerEventExecutor() did sometimes fail as we sometimes miss to count down the latch. This can happen when we remove the handler from the pipeline before channelUnregistered(...) was called for it.

Modifications:

Countdown the latch in handlerRemoved(...).

Result:

Fix flaky test.

Motivation:
I want to fix bug in vert.x project (eclipse-vertx/vert.x#2562) caused by ComposedLastHttpContent result being null. I don't know if it is intentional that this last decoded chuck in the issue returns null, but if not - I am providing fix for that.

Modification:
* Added new constructor in ComposedLastHttpContent allowing to pass DecoderResult
* set DecoderResult.SUCCESS for created ComposedLastHttpContent in HttpContentEncoder
* set DecoderResult.SUCCESS for created ComposedLastHttpContent in HttpContentDecoder

Ensure FlowControlled data frames will be correctly removed from the … (#8726)
Motivation:

When a write error happens during writing of flowcontrolled data frames we miss to correctly detect this in the write loop which may result in an infinite loop as we will never detect that the frame should be removed from the queue.

Modifications:

- When we fail a flowcontrolled data frame we ensure that the next frame.write(...) call will signal back that the whole frame was handled and so can be removed.
- Add unit test.

Result:

Fixes https://github.com/netty/netty/issues/8707.

Only handle NXDOMAIN as failure when nameserver is authoritive or no other nameservers are left. (#8731)
Motivation:

When using multiple nameservers and a nameserver respond with NXDOMAIN we should only fail the query if the nameserver in question is authoritive or no nameservers are left to try.

Modifications:

- Try next nameserver if NXDOMAIN was returned but the nameserver is not authoritive
- Adjust testcase to respect correct behaviour.

Result:

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:

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();`

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:

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 .

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.

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.

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:

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.
