4b8db65b16 Allow null sender when using DatagramPacketEncoder (#9204)
Motivation:

It is valid to use null as sender so we should support it when DatagramPacketEncoder checks if it supports the message.

Modifications:

- Add null check
- Add unit test

Result:

Fixes https://github.com/netty/netty/issues/9199.

a63584715f ByteToMessageDecoder.handlerRemoved(...) should only call fireChannelReadComplete() if fireChannelRead(...) was called before (#9211)
Motivation:

At the moment ByteToMessageDecoder always calls fireChannelReadComplete() when the handler is removed from the pipeline and the cumulation buffer is not null. We should only call it when we also call fireChannelRead(...), which only happens if the cumulation buffer is not null and readable.

Modifications:

Only call fireChannelReadComplete() if fireChannelRead(...) is called before during removal of the handler.

Result:

More correct semantics

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.

ed61e5f543 Only use static Exception instances when we can ensure addSuppressed … (#9152)
Motivation:

OOME is occurred by increasing suppressedExceptions because other libraries call Throwable#addSuppressed. As we have no control over what other libraries do we need to ensure this can not lead to OOME.

Modifications:

Only use static instances of the Exceptions if we can either dissable addSuppressed or we run on java6.

Result:

Not possible to OOME because of addSuppressed. Fixes https://github.com/netty/netty/issues/9151.

3c11af965a DefaultHeaders#valueIterator doesn't remove from the in bucket list (#9090)
Motivation:
DefaultHeaders entries maintains two linked lists. 1 for overall insertion order
and 1 for "in bucket" order. DefaultHeaders#valueIterator removal (introduced in 1d9090aab2) only reliably
removes the entry from the overall insertion order, but may not remove from the
bucket unless the element is the first entry.

Modifications:
- DefaultHeaders$ValueIterator should track 2 elements behind the next entry so
that the single linked "in bucket" list can be patched up when removing the
previous entry.

Result:
More correct DefaultHeaders#valueIterator removal.

7e469b764e DefaultHeaders#valueIterator to support removal (#9063)
Motivation:
While iterating values it is often desirable to be able to remove individual
entries. The existing mechanism to do this involves removal of all entries and
conditional re-insertion which is heavy weight in order to remove a single
value.

Modifications:
- DefaultHeaders$ValueIterator supports removal

Result:
It is possible to remove entries while iterating the values in DefaultHeaders.

077b1fc4d9 Correctly discard messages after oversized message is detected. (#9015)
Motivation:

32563bfcc1 introduced a regression in which we did now not longer discard the messages after we handled an oversized message.

Modifications:

- Do not set aggregating to false after handleOversizedMessage is called
- Adjust unit tests to verify the behaviour is correct again.

Result:

Fixes https://github.com/netty/netty/issues/9007.

Merge ChannelInboundHandler and ChannelOutboundHandler into ChannelHa… (#8957)
Motivation:

In 42742e233f we already added default methods to Channel*Handler and deprecated the Adapter classes to simplify the class hierarchy. With this change we go even further and merge everything into just ChannelHandler. This simplifies things even more in terms of class-hierarchy.

Modifications:

- Merge ChannelInboundHandler | ChannelOutboundHandler into ChannelHandler
- Adjust code to just use ChannelHandler
- Deprecate old interfaces.

Result:

Cleaner and simpler code in terms of class-hierarchy.

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.

f58d074caf Tighten up contract of PromiseCombiner and so make it more safe to use (#8886)
Motivation:

PromiseCombiner is not thread-safe and even assumes all added Futures are using the same EventExecutor. This is kind of fragile as we do not enforce this. We need to enforce this contract to ensure it's safe to use and easy to spot concurrency problems.

Modifications:

- Add new contructor to PromiseCombiner that takes an EventExecutor and deprecate the old non-arg constructor.
- Check if methods are called from within the EventExecutor thread and if not fail
- Correctly dispatch on the right EventExecutor if the Future uses a different EventExecutor to eliminate concurrency issues.

Result:

More safe use of PromiseCombiner + enforce correct usage / contract.

2e433889b2 Improve DateFormatter parsing performance (#8821)
Motivation:

Just was looking through code and found 1 interesting place DateFormatter.tryParseMonth that was not very effective, so I decided to optimize it a bit.

Modification:

Changed DateFormatter.tryParseMonth method. Instead of invocation regionMatch() for every month - compare chars one by one.

Result:

DateFormatter.parseHttpDate method performance improved from ~3% to ~15%.

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.

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 .

37e471dbe6 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.

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.

6563f23a9b Don't swallow intermediate write failures in MessageToMessageEncoder (#8454)
Motivation:

If the encoder needs to flush more than one outbound message it will
create a new ChannelPromise for all but the last write which will
swallow failures.

Modification:

Use a PromiseCombiner in the case of multiple messages and the parent
promise isn't the `VoidPromise`.

Result:

Intermediate failures are propagated to the original ChannelPromise.

d7fa7be67f Exploit PlatformDependent.allocateUninitializedArray() in more places (#8393)
Motivation:

There are currently many more places where this could be used which were
possibly not considered when the method was added.

If https://github.com/netty/netty/pull/8388 is included in its current
form, a number of these places could additionally make use of the same
BYTE_ARRAYS threadlocal.

There's also a couple of adjacent places where an optimistically-pooled
heap buffer is used for temp byte storage which could use the
threadlocal too in preference to allocating a temp heap bytebuf wrapper.
For example
https://github.com/netty/netty/blob/4.1/buffer/src/main/java/io/netty/buffer/ByteBufUtil.java#L1417.

Modifications:

Replace new byte[] with PlatformDependent.allocateUninitializedArray()
where appropriate; make use of ByteBufUtil.getBytes() in some places
which currently perform the equivalent logic, including avoiding copy of
backing array if possible (although would be rare).

Result:

Further potential speed-up with java9+ and appropriate compile flags.
Many of these places could be on latency-sensitive code paths.

583d838f7c Optimize AbstractByteBuf.getCharSequence() in US_ASCII case (#8392)
* Optimize AbstractByteBuf.getCharSequence() in US_ASCII case

Motivation:

Inspired by https://github.com/netty/netty/pull/8388, I noticed this
simple optimization to avoid char[] allocation (also suggested in a TODO
here).

Modifications:

Return an AsciiString from AbstractByteBuf.getCharSequence() if
requested charset is US_ASCII or ISO_8859_1 (latter thanks to
@Scottmitch's suggestion). Also tweak unit tests not to require Strings
and include a new benchmark to demonstrate the speedup.

c58069f284 Better handling of streaming JSON data in JsonObjectDecoder (#7821)
Motivation:

When the JsonObjectDecoder determines that the incoming buffer had some data discarded, it resets the internal index to readerIndex and attempts to adjust the state which does not correctly work for streams of JSON objects.

Modifications:

Reset the internal index to the value considering the previous reads.

Result:

JsonObjectDecoder correctly handles streams of both JSON objects and arrays with no state adjustments or repeatable reads.

f40ecc3f10 Fix Snappy decoding of large 2-byte literal lengths and copy offsets
Motivation:

The Snappy decoder was failing on valid inputs containing literals
with 2-byte lengths > 0x8000 or copies with 2-byte offsets >= 0x8000.

The decoder was also enforcing an artificially low offset limit of
0x7FFF, something the Snappy format description advises against,
and which prevents decoding valid inputs generated by other encoders.

Modifications:

Interpret 2-byte literal lengths and 2-byte copy offsets as unsigned
shorts, in accordance with the format description and reference
implementation.

Allow any positive offset value. Throw an appropriate exception
for negative values (which can theoretically occur due to arithmetic
overflow on 4-byte offsets, but are unlikely to occur in the wild).

Result:

The Snappy decoder can handle valid inputs that previously caused
it to throw exceptions.

1e5fafe446 Simplify CharSequenceValueConverter#convertToBoolean
Motivation:
CharSequenceValueConverter#convertToBoolean has a few manual conditionals which can be removed if we use AsciiString.contentEqualsIgnoreCase. Also by comparing an AsciiString to a String we will incur conversions to char that can be avoided if we compare against AsciiString.

Modifications:
- Use AsciiString.contentEqualsIgnoreCase
- Compare against a AsciiString

Result:
Simplified CharSequenceValueConverter#convertToBoolean which favors AsciiString comparison.

c1d0d88f0a Implement DefaultHeaders.HeaderEntry.equals()
Motivation:

HeaderEntry.equals() inherets Object.equals() which simply check if two objects are the same.
So it returns false even when two HeaderEntry objects have the same name and value.

Modifications:

Implement HeaderEntry.equals() that follows the specification of Map.Entry.equals().
https://docs.oracle.com/javase/9/docs/api/java/util/Map.Entry.html#equals-java.lang.Object-

Result:

HeaderEntry.equals() returns true if two HeaderEntry objects have the same name and value.

4c1e0f596a Use FastThreadLocal for CodecOutputList
Motivation:

We used Recycler for the CodecOutputList which is not optimized for the use-case of access only from the same Thread all the time.

Modifications:

- Use FastThreadLocal for CodecOutputList
- Add benchmark

Result:

Less overhead in our codecs.
