b83ffcc447 Add timeout to PooledByteBufAllocatorTest
Motivation:

Some tests in PooledByteBufAllocatorTest are blocking on a CountDownLatch. We should use a timeout on these tests so these will not block forever on a failure.

Modifications:

Add timeout param to @Test annotation

Result:

Have sane timeouts on tests.

e59d0e9efb Introduce CodecOutputList to reduce overhead of encoder/decoder
Motivation:

99dfc9ea79 introduced some code that will more frequently try to forward messages out of the list of decoded messages to reduce latency and memory footprint. Unfortunally this has the side-effect that RecycleableArrayList.clear() will be called more often and so introduce some overhead as ArrayList will null out the array on each call.

Modifications:

- Introduce a CodecOutputList which allows to not null out the array until we recycle it and also allows to access internal array with extra range checks.
- Add benchmark that add elements to different List implementations and clear them

Result:

Less overhead when decode / encode messages.

a425a8551d [#5174] Expose Bootstrap getter methods and add some additional ones
Motivation:

The Bootstrap class (applies also to AbstractBootstrap and ServerBootstrap) has a few package private getter methods and some things such as #attr() and #options() aren't exposed at all.

Modifications:

Expose "getters" for configured things in a safe-manner via the config() method.

Result:

Easier for the user to check what is configured for a Bootstrap/ServerBootstrap.

f11a35af32 Replace DomainMappingBuilder with DomainNameMappingBuilder
Motivation:

DomainMappingBuilder should have been named as DomainNameMappingBuilder
because it builds a DomainNameMapping.

Modifications:

- Add DomainNameMappingBuilder that does the same job with
  DomainMappingBuilder
- Deprecate DomainMappingBuilder and delegate its logic to
  DomainNameMappingBuilder
- Remove the references to the deprecated methods and classes related
  with domain name mapping
- Miscellaneous:
  - Fix Javadoc of DomainNameMapping.asMap()
  - Pre-create the unmodifiable map in DomainNameMapping

Result:

- Consistent naming
- Less use of deprecated API

ea1f60dbf0 Replace DomainNameMapping.entries() with asMap()
Motivation:

DomainNameMapping.entries() returns Set<Map.Entry<String, V>>, which
doesn't sound very natural.

Modifications:

Replace entries() with asMap() which returns a Map<String, V> instead.

Result:

- Better looking API
- User can do a lookup because it's a Map

55dd7d035f Fix a class loader leak in ForkJoinPool
Motivation:

As reported in #4211, when using Netty in Tomcat (or other container based deployment), ForkJoinPool leaks an instance of `Submitter` so that the class loader of `Submitter` won't be GCed. However, since `Submitter` is just a wrapper of `int`, we can replace it with `int[1]`.

Modifications:

Replace `Submitter` with `int[1]`.

Result:

No class loader leak in ForkJoinPool when using in a container.

2b340df452 DuplexChannel to support shutdownInput
Motivation:
The DuplexChannel is currently incomplete and only supports shutting down the output side of a channel. This interface should also support shutting down the input side of the channel.

Modifications:
- Add shutdownInput and shutdown methods to the DuplexChannel interface
- Remove state in NIO and OIO for tracking input being shutdown independent of the underlying transport's socket type. Tracking the state independently may lead to inconsistent state.

Result:
DuplexChannel supports shutting down the input side of the channel

1cb706ac93 HTTP/2 HPACK Header Name Validation and Trailing Padding
Motivation:
The HPACK code currently disallows empty header names. This is not explicitly forbidden by the HPACK RFC https://tools.ietf.org/html/rfc7541. However the HTTP/1.x RFC https://tools.ietf.org/html/rfc7230#section-3.2 and thus HTTP/2 both disallow empty header names, and so this precondition check should be moved from the HPACK code to the protocol level.
HPACK also requires that string literals which are huffman encoded must be treated as an encoding error if the string has more than 7 trailing padding bits https://tools.ietf.org/html/rfc7541#section-5.2, but this is currently not enforced.

Result:
- HPACK to allow empty header names
- HTTP/1.x and HTTP/2 header validation should not allow empty header names
- Enforce max of 7 trailing padding bits

Result:
Code is more compliant with the above mentioned RFCs

a517cce92f Do not send duplicate DNS queries when the same query is in progress already
Related issue: #5179

Motivation:

When you attempt to make a lot of connection attempts to the same target
host at the same time and our DNS resolver does not have a record for it
in the cache, the DNS resolver will send as many DNS queries as the
number of connection attempts.

As a result, DNS server will reject or drop the requests, making the
name resolution attempt fail.

Modifications:

- Add InflightNameResolver that keeps the list of name resolution
  queries and subscribes to the future of the matching query instead of
  sending a duplicate query.

Result:

- The AddressResolvers created by DnsAddressResolverGroup do not send
  duplicate DNS queries anymore

8fe3c83e4c [#5104] Fix possible deadlock in DefaultChannelPipeline
Motivation:

When a user has multiple EventLoops in an EventLoopGroup and calls pipeline.add* / remove* / replace from an EventLoop that belongs to another Channel it is possible to deadlock if the other EventLoop does the same.

Modification:

- Only ensure the actual modification takes place in a synchronized block and not wait until the handlerAdded(...) / handlerRemoved(...) method is called. This is ok as we submit the task to the executor while still holding the look and so ensure correct order of pipeline modifications.
- Ensure if an AbstractChannelHandlerContext is put in the linked-list structure but the handlerAdded(...) method was not called we skip it until handlerAdded(...) was called. This is needed to ensure handlerAdded(...) is always called first.

Result:

Its not possible to deadlock when modify the DefaultChannelPipeline.

3a9f472161 Make retained derived buffers recyclable
Related: #4333 #4421 #5128

Motivation:

slice(), duplicate() and readSlice() currently create a non-recyclable
derived buffer instance. Under heavy load, an application that creates a
lot of derived buffers can put the garbage collector under pressure.

Modifications:

- Add the following methods which creates a non-recyclable derived buffer
  - retainedSlice()
  - retainedDuplicate()
  - readRetainedSlice()
- Add the new recyclable derived buffer implementations, which has its
  own reference count value
- Add ByteBufHolder.retainedDuplicate()
- Add ByteBufHolder.replace(ByteBuf) so that..
  - a user can replace the content of the holder in a consistent way
  - copy/duplicate/retainedDuplicate() can delegate the holder
    construction to replace(ByteBuf)
- Use retainedDuplicate() and retainedSlice() wherever possible
- Miscellaneous:
  - Rename DuplicateByteBufTest to DuplicatedByteBufTest (missing 'D')
  - Make ReplayingDecoderByteBuf.reject() return an exception instead of
    throwing it so that its callers don't need to add dummy return
    statement

Result:

Derived buffers are now recycled when created via retainedSlice() and
retainedDuplicate() and derived from a pooled buffer

68cd670eb9 Remove ChannelHandlerInvoker
Motivation:

We tried to provide the ability for the user to change the semantics of the threading-model by delegate the invoking of the ChannelHandler to the ChannelHandlerInvoker. Unfortunually this not really worked out quite well and resulted in just more complexity and splitting of code that belongs together. We should remove the ChannelHandlerInvoker again and just do the same as in 4.0

Modifications:

Remove ChannelHandlerInvoker again and replace its usage in Http2MultiplexCodec

Result:

Easier code and less bad abstractions.

f44f3e7926 NioEventLoop ensures that all submitted tasks are executed immediately.
Motivation:
If a task was submitted when wakenUp value was true, the task didn't get a chance to call Selector#wakeup.
So we need to check task queue again before executing select operation. If we don't, the task might be pended until select operation was timed out.
It might be pended until idle timeout if IdleStateHandler existed in pipeline.

Modifications:
Execute Selector#select in a non-blocking manner if there's a task submitted when wakenUp value was true.

Result:
Every tasks in NioEventLoop will not be pended.

c249926784 [#3127] Allow to write with VoidPromise to Channels in ChannelGroup
Motivation:

Users sometimes want to use Channel.voidPromise() when write to a Channel to reduce GC-pressure. This should be also possible when write via a ChannelGroup.

Modifications:

Add new write(...) and writeAndFlush(...) overloads which allow to signale that a VoidPromise should be used to write to the Channel

775dd139ea Ensure Bootstrap.connect(...) not throw IllegalStateException when registration is delayed.
Motivation:

Bootstrap.connect(...) tries to obtain the EventLoop of a Channel before it may be registered. This will cause an IllegalStateException. We need to ensure we handle the cause of late registration and not throw in this case.

Modifications:

Ensure we only try to access the EventLoop after the Channel is registered and handle the case of late registration.

Result:

Bootstrap.connect(...) not fails on late registration.

Motivation:

Sometimes it is useful to include more details in the IdleStateEvents that are produced by the IdleStateHandler. For this users should be able to create their own IdleStateEvents that encapsulate more informations.

Modifications:

- Make IdleStateEvent constructor protected and the class non-final
- Add protected method to IdleStateHandler that users can override and so create their own IdleStateEvents.

Result:

More flexible and customizable IdleStateEvents / IdleStateHandler

1f8e192e21 Remove EventExecutor.children
Motivation:
EventExecutor.children uses generics in such a way that an entire colleciton must be cast to a specific type of object. This interface is not very flexible and is impossible to implement if the EventExecutor type must be wrapped. The current usage of this method also does not have any clear need within Netty. The Iterator interface allows for EventExecutor to be wrapped and forces the caller to make assumptions about types instead of building the assumptions into the interface.

Motivation:
- Remove EventExecutor.children and undeprecate the iterator() interface

Result:
EventExecutor interface has one less method and is easier to wrap.

88a52f7367 KObjectHashMap PrimitiveIterator NPE
Motivation:
KObjectHashMap.remove(int index) attempts to move back items which may have been displaced because their spot in the hash based array was taken by another item. If this happens the nextIndex reference in PrimitiveIterator will not be updated. At this time the PrimitiveEntry will reference the incorrect index and may result in a NPE.

Modifications:
- If KObjectHashMap.remove(int index) moves entries back then PrimitiveIterator should adjust its nextIndex

Result:
PrimitiveIterator.remove() updates its internal state to reference the new nextIndex and will not NPE.

690ab563e7 Ensure ChannelHandlerContext.attr(...) and ChannelHandlerContext.hasAttr(...) has no semantic change
Motivation:

The ChannelHandlerContext.attr(...) and ChannelHandlerContext.hasAttr(...) delegated to Channel for the attributes which is a semantic change compared to 4.0 releases. We should not change the semantic to not break users applications when upgrading to 4.1.0

Modifications:

- Revert semantic change
- Mark ChannelHandlerContext.attr(...) and hasAttr(...) as @deprecated so we can remove these later

Result:

Semantic of attribute operations on ChannelHandlerContext is the same in 4.1 as in 4.0 again.

Motivation:

Resolving hosts via the /etc/hosts file should be case-insensitive, e.g. localhost and LOCALHOST refer to the same host, this is the same that is applied to dns queries.

Modifications:

Store hosts Map with lowercase keys, lookup the keys as lowercase
Add to unit test for the hosts file parser to use an UPPERCASE file entry
Add unit test for DefaultHostsFileEntriesResolver to resolve both localhost and LOCALHOST

d580245afc DefaultHttp2Connection.close Reentrant Modification
Motivation:
The DefaultHttp2Conneciton.close method accounts for active streams being iterated and attempts to avoid reentrant modifications of the underlying stream map by using iterators to remove from the stream map. However there are a few issues:

- While iterating over the stream map we don't prevent iterations over the active stream collection
- Removing a single stream may actually remove > 1 streams due to closed non-leaf streams being preserved in the priority tree which may result in NPE

Preserving closed non-leaf streams in the priority tree is no longer necessary with our current allocation algorithms, and so this feature (and related complexity) can be removed.

Modifications:
- DefaultHttp2Connection.close should prevent others from iterating over the active streams and reentrant modification scenarios which may result from this
- DefaultHttp2Connection should not keep closed stream in the priority tree
  - Remove all associated code in DefaultHttp2RemoteFlowController which accounts for this case including the ReducedState object
  - This includes fixing writability changes which depended on ReducedState
- Update unit tests

9ce84dcb21 Http2 to Http1.1 converter on new Http2 server API
Motivation:

http/2 and http/1.1 have similar protocols, and it's useful to be able
to implement a single server against a single interface. There's an
injection from http/1.1 messages to http/2 ones, so it makes sense to
make folks program against http/1.1 and upgrade them under the hood.

Modifications:

added a MessageToMessageCodec<Http2StreamFrame, HttpObject> which turns
every kind of Http2StreamFrame domain object into an HttpObject domain
object, and then back again on the way out.  This one is specialized for
servers, but it should be straightforward to make a symmetric one for
clients, or else extend this one.

Result:

fixes #5199, and it's now simple to make your Http2MultiplexCodec speak

f2ed3e6ce8 DefaultPromise LateListener Logic Issues
Motivation:
The LateListener logic is prone to infinite loops and relies on being processed in the EventExecutor's thread for synchronization, but this EventExecutor may not be constant. An infinite loop can occur if the EventExecutor's execute method does not introduce a context switch in LateListener.run. The EventExecutor can be changed by classes which inherit from DefaultPromise. For example the DefaultChannelPromise will return w/e EventLoop the channel is registered to, but this EventLoop can change (re-registration).

Modifications:
- Remove the LateListener concept and instead use a single Object to maintain the listeners while still preserving notification order
- Make the result member variable an atomic variable so it can be outside the synchronized(this) blocks
- Cleanup/simplify existing state management code

Result:
Fixes https://github.com/netty/netty/issues/5185

b2bb72b2de [#5171] Ensure NioDatagramChannelConfig can be instanced on android
Motivation:

NioDatagramChannelConfig currently uses NetworkChannel in its static { } block and so fails to init on android which not has this class.

Modifications:

Use reflection to load the NetworkChannel.class

Result:

Be able to use NIO Datagram on android as well.
