f990f9983d HTTP/2 Don't Flow Control Iniital Headers
Motivation:
Currently the initial headers for every stream is queued in the flow controller. Since the initial header frame may create streams the peer must receive these frames in the order in which they were created, or else this will be a protocol error and the connection will be closed. Tolerating the initial headers being queued would increase the complexity of the WeightedFairQueueByteDistributor and there is benefit of doing so is not clear.

Modifications:
- The initial headers will no longer be queued in the flow controllers

Result:
Fixes https://github.com/netty/netty/issues/4758

6dbb610f5b Add ChannelHandlerContext.invoker()
Motivation:

Being able to access the invoker() is useful when adding additional
handlers that should be running in the same thread. Since an application
may be using a threading model unsupported by the default invoker, they
can specify their own. Because of that, in a handler that auto-adds
other handlers:

// This is a good pattern
ctx.pipeline().addBefore(ctx.invoker(), ctx.name(), null, newHandler);
// This will generally work, but prevents using custom invoker.
ctx.pipeline().addBefore(ctx.executor(), ctx.name(), null, newHandler);

That's why I believe in commit 110745b0, for the now-defunct 5.0 branch,
when ChannelHandlerAppender was added the invoker() method was also
necessary.

There is a side-benefit to exposing the invoker: in certain advanced
use-cases using the invoker for a particular handler is useful. Using
the invoker you are able to invoke a _particular_ handler, from possibly
a different thread yet still using standard exception processing.

ChannelHandlerContext does part of that, but is unwieldy when trying to
invoke a particular handler because it invokes the prev or next handler,
not the one the context is for. A workaround is to use the next or prev
context (respectively), but this breaks when the pipeline changes.

This came up during writing the Http2MultiplexCodec which uses a
separate child channel for each http/2 stream and wants to send messages
from the child channel directly to the Http2MultiplexCodec handler that
created it.

Modifications:

Add the invoker() method to ChannelHandlerContext. It was already being
implemented by AbstractChannelHandlerContext. The two other
implementations of ChannelHandlerContext needed minor tweaks.

Result:

Access to the invoker used for a particular handler, for either reusing
for other handlers or for advanced use-cases. Fixes #4738

904e70a4d4 HTTP/2 Weighted Fair Queue Byte Distributor
Motivation:
PriorityStreamByteDistributor uses a homegrown algorithm which distributes bytes to nodes in the priority tree. PriorityStreamByteDistributor has no concept of goodput which may result in poor utilization of network resources. PriorityStreamByteDistributor also has performance issues related to the tree traversal approach and number of nodes that must be visited. There also exists some more proven algorithms from the resource scheduling domain which PriorityStreamByteDistributor does not employ.

Modifications:
- Introduce a new ByteDistributor which uses elements from weighted fair queue schedulers

Result:
StreamByteDistributor which is sensitive to priority and uses a more familiar distribution concept.

2202e8f967 Revamp the Http2ConnectionHandler builder API
Related: #4572

Motivation:

- A user might want to extend Http2ConnectionHandler and define his/her
  own static inner Builder class that extends
  Http2ConnectionHandler.BuilderBase. This introduces potential
  confusion because there's already Http2ConnectionHandler.Builder. Your
  IDE will warn about this name duplication as well.
- BuilderBase exposes all setters with public modifier. A user's Builder
  might not want to expose them to enforce it to certain configuration.
  There's no way to hide them because it's public already and they are
  final.
- BuilderBase.build(Http2ConnectionDecoder, Http2ConnectionEncoder)
  ignores most properties exposed by BuilderBase, such as
  validateHeaders, frameLogger and encoderEnforceMaxConcurrentStreams.
  If any build() method ignores the properties exposed by the builder,
  there's something wrong.
- A user's Builder that extends BuilderBase might want to require more
  parameters in build(). There's no way to do that cleanly because
  build() is public and final already.

Modifications:

- Make BuilderBase and Builder top-level so that there's no duplicate
  name issue anymore.
  - Add AbstractHttp2ConnectionHandlerBuilder
  - Add Http2ConnectionHandlerBuilder
  - Add HttpToHttp2ConnectionHandlerBuilder
- Make all builder methods in AbstractHttp2ConnectionHandlerBuilder
  protected so that a subclass can choose which methods to expose
- Provide only a single build() method
  - Add connection() and codec() so that a user can still specify
    Http2Connection or Http2Connection(En|De)coder explicitly
  - Implement proper state validation mechanism so that it is prevented
    to invoke conflicting setters

Result:

Less confusing yet flexible builder API

641505a5d2 DefaultChannelConfig maxMessagesPerRead default not always set
Motivation:
ChannelMetadata has a field minMaxMessagesPerRead which can be confusing. There are also some cases where static instances are used and the default value for channel type is not being applied.

Modifications:
- use a default value which is set unconditionally to simplify
- make sure static instances of MaxMessagesRecvByteBufAllocator are not used if the intention is that the default maxMessagesPerRead should be derived from the channel type.

Result:
Less confusing interfaces in ChannelMetadata and ChannelConfig. Default maxMessagesPerRead is correctly applied.

2a2059d976 Adding UniformStreamByteDistributor
Motivation:

The current priority algorithm can yield poor per-stream goodput when either the number of streams is high or the connection window is small. When all priorities are the same (i.e. priority is disabled), we should be able to do better.

Modifications:

Added a new UniformStreamByteDistributor that ignores priority entirely and manages a queue of streams.  Each stream is allocated a minimum of 1KiB on each iteration.

Result:

Improved goodput when priority is not used.

6504d52b94 Add HTTP/2 local flow control option for auto refill
Motivation:

For many HTTP/2 applications (such as gRPC) it is necessary to autorefill the connection window in order to prevent application-level deadlocking.

Consider an application with 2 streams, A and B.  A receives a stream of messages and the application pops off one message at a time and makes a request on stream B. However, if receiving of data on A has caused the connection window to collapse, B will not be able to receive any data and the application will deadlock.  The only way (currently) to get around this is 1) use multiple connections, or 2) manually refill the connection window.  Both are undesirable and could needlessly complicate the application code.

Modifications:

Add a configuration option to DefaultHttp2LocalFlowController, allowing it to autorefill the connection window.

Result:

Applications can configure HTTP/2 to avoid inter-stream deadlocking.

19658e9cd8 HTTP/2 Headers Type Updates
Motivation:
The HTTP/2 RFC (https://tools.ietf.org/html/rfc7540#section-8.1.2) indicates that header names consist of ASCII characters. We currently use ByteString to represent HTTP/2 header names. The HTTP/2 RFC (https://tools.ietf.org/html/rfc7540#section-10.3) also eludes to header values inheriting the same validity characteristics as HTTP/1.x. Using AsciiString for the value type of HTTP/2 headers would allow for re-use of predefined HTTP/1.x values, and make comparisons more intuitive. The Headers<T> interface could also be expanded to allow for easier use of header types which do not have the same Key and Value type.

Motivation:
- Change Headers<T> to Headers<K, V>
- Change Http2Headers<ByteString> to Http2Headers<CharSequence, CharSequence>
- Remove ByteString. Having AsciiString extend ByteString complicates equality comparisons when the hash code algorithm is no longer shared.

Result:
Http2Header types are more representative of the HTTP/2 RFC, and relationship between HTTP/2 header name/values more directly relates to HTTP/1.x header names/values.

c9364616c8 Fix performance regression in FastThreadLocal microbenchmark. Fixes #4402
Motivation:

As reported in #4402, the FastThreadLocalBenchmark shows that the JDK ThreadLocal
is actually faster than Netty's custom thread local implementation.

I was looking forward to doing some deep digging, but got disappointed :(.

Modifications:

The microbenchmark was not using FastThreadLocalThreads and would thus always hit the slow path.
I updated the JMH command line flags, so that FastThreadLocalThreads would be used.

Result:

FastThreadLocalBenchmark shows FastThreadLocal to be faster than JDK's ThreadLocal implementation,
by about 56% in this particular benchmark. Run on OSX El Capitan with OpenJDK 1.8u60.

a47685b243 Use bitwise operation when sampling for resource leak detection.
Motivation:

Modulo operations are slow, we can use bitwise operation to detect if resource leak detection must be done while sampling.

Modifications:

- Use bitwise operation for sampling
- Add benchmark.

Result:

Faster sampling.

4c287d4e27 Added SlicedAbstractByteBuf that can provide fast-path for _get* and _set* methods
Motivation:

SlicedByteBuf can be used for any ByteBuf implementations and so can not do any optimizations that could be done
when AbstractByteBuf is sliced.

Modifications:

- Add SlicedAbstractByteBuf that can eliminate range and reference count checks for _get* and _set* methods.

Result:

Faster SlicedByteBuf implementations for AbstractByteBuf sub-classes.

9697afc106 Allow to disable reference count checks on every access of the ByteBuf
Motiviation:

Checking reference count on every access on a ByteBuf can have some big performance overhead depending on how the access pattern is. If the user is sure that there are no reference count errors on his side it should be possible to disable the check and so gain the max performance.

Modification:

- Add io.netty.buffer.bytebuf.checkAccessible system property which allows to disable the checks. Enabled by default.
- Add microbenchmark

Result:

Increased performance for operations on the ByteBuf.

284e3702d8 Http2ConnectionHandler Builder instead of constructors
Motivation:
Using the builder pattern for Http2ConnectionHandler (and subclasses) would be advantageous for the following reasons:
1. Provides the consistent construction afforded by the builder pattern for 'optional' arguments. Users can specify these options 1 time in the builder and then re-use the builder after this.
2. Enforces that the Http2ConnectionHandler's internals (decoder Http2FrameListener) are initialized after construction.

Modifications:
- Add an extensible builder which can be used to build Http2ConnectionHandler objects
- Update classes which inherit from Http2ConnectionHandler

Result:
It is easier to specify options and construct Http2ConnectionHandler objects.

1485a87e25 Http2ConnectionHandler and Http2FrameListener cyclic dependency
Motivation:
It is often the case that implementations of Http2FrameListener will want to send responses when data is read. The Http2FrameListener needs access to the Http2ConnectionHandler (or the encoder contained within) to be able to send responses. However the Http2ConnectionHandler requires a Http2FrameListener instance to be passed in during construction time. This creates a cyclic dependency which can make it difficult to cleanly accomplish this relationship.

Modifications:
- Add Http2ConnectionDecoder.frameListener(..) method to set the frame listener. This will allow the listener to be set after construction.

Result:
Classes which inherit from Http2ConnectionHandler can more cleanly set the Http2FrameListener.

0e9545e94d Http2RemoteFlowController stream writibility listener
Motivation:
For implementations that want to manage flow control down to the stream level it is useful to be notified when stream writability changes.

Modifications:
- Add writabilityChanged to Http2RemoteFlowController.Listener
- Add isWritable to Http2RemoteFlowController

Result:
The Http2RemoteFlowController provides notification when writability of a stream changes.

Motivation:

The latest netty-tcnative fixes a bug in determining the version of the runtime openssl lib.  It also publishes an artificact with the classifier linux-<arch>-fedora for fedora-based systems.

Modifications:

Modified the build files to use the "-fedora" classifier when appropriate for tcnative. Care is taken, however, to not change the classifier for the native epoll transport.

Result:

6fd0a0c55f Faster and more memory efficient headers for HTTP, HTTP/2, STOMP and SPYD. Fixes #3600
Motivation:

We noticed that the headers implementation in Netty for HTTP/2 uses quite a lot of memory
and that also at least the performance of randomly accessing a header is quite poor. The main
concern however was memory usage, as profiling has shown that a DefaultHttp2Headers
not only use a lot of memory it also wastes a lot due to the underlying hashmaps having
to be resized potentially several times as new headers are being inserted.

This is tracked as issue #3600.

Modifications:
We redesigned the DefaultHeaders to simply take a Map object in its constructor and
reimplemented the class using only the Map primitives. That way the implementation
is very concise and hopefully easy to understand and it allows each concrete headers
implementation to provide its own map or to even use a different headers implementation
for processing requests and writing responses i.e. incoming headers need to provide
fast random access while outgoing headers need fast insertion and fast iteration. The
new implementation can support this with hardly any code changes. It also comes
with the advantage that if the Netty project decides to add a third party collections library
as a dependency, one can simply plug in one of those very fast and memory efficient map
implementations and get faster and smaller headers for free.

For now, we are using the JDK's TreeMap for HTTP and HTTP/2 default headers.

Result:

- Significantly fewer lines of code in the implementation. While the total commit is still
  roughly 400 lines less, the actual implementation is a lot less. I just added some more
  tests and microbenchmarks.

- Overall performance is up. The current implementation should be significantly faster
  for insertion and retrieval. However, it is slower when it comes to iteration. There is simply
  no way a TreeMap can have the same iteration performance as a linked list (as used in the
  current headers implementation). That's totally fine though, because when looking at the
  benchmark results @ejona86 pointed out that the performance of the headers is completely
  dominated by insertion, that is insertion is so significantly faster in the new implementation
  that it does make up for several times the iteration speed. You can't iterate what you haven't
  inserted. I am demonstrating that in this spreadsheet [1]. (Actually, iteration performance is
  only down for HTTP, it's significantly improved for HTTP/2).

- Memory is down. The implementation with TreeMap uses on avg ~30% less memory. It also does not
  produce any garbage while being resized. In load tests for GRPC we have seen a memory reduction
  of up to 1.2KB per RPC. I summarized the memory improvements in this spreadsheet [1]. The data
  was generated by [2] using JOL.

- While it was my original intend to only improve the memory usage for HTTP/2, it should be similarly
  improved for HTTP, SPDY and STOMP as they all share a common implementation.

- Update HttpObjectDecoder methods to take advantage of new AppendableCharSequence methods.

Result:
Peformance boost for decoding http objects.

9747ffe5fc HTTP/2 Flow Controller should use Channel.isWritable()
Motivation:
See #3783

Modifications:
- The DefaultHttp2RemoteFlowController should use Channel.isWritable() before attempting to do any write operations.
- The Flow controller methods should no longer take ChannelHandlerContext. The concept of flow control is tied to a connection and we do not support 1 flow controller keeping track of multiple ChannelHandlerContext.

Result:
Writes are delayed until isWritable() is true. Flow controller interface methods are more clear as to ChannelHandlerContext restrictions.

05ce33f5ca Make the flow-controllers write fewer, fatter frames to improve throughput.
Motivation:

Coalescing many small writes into a larger DATA frame reduces framing overheads on the wire and reduces the number of calls to Http2FrameListeners on the remote side.
Delaying the write of WINDOW_UPDATE until flush allows for more consumed bytes to be returned as the aggregate of consumed bytes is returned and not the amount consumed when the threshold was crossed.

Modifications:
- Remote flow controller no longer immediately writes bytes when a flow-controlled payload is enqueued. Sequential data payloads are now merged into a single CompositeByteBuf which are written when 'writePendingBytes' is called.
- Listener added to remote flow-controller which observes written bytes per stream.
- Local flow-controller no longer immediately writes WINDOW_UPDATE when the ratio threshold is crossed. Now an explicit call to 'writeWindowUpdates' triggers the WINDOW_UPDATE for all streams who's ratio is exceeded at that time. This results in
  fewer window updates being sent and more bytes being returned.
- Http2ConnectionHandler.flush triggers 'writeWindowUpdates' on the local flow-controller followed by 'writePendingBytes' on the remote flow-controller so WINDOW_UPDATES preceed DATA frames on the wire.

Result:
- Better throughput for writing many small DATA chunks followed by a flush, saving 9-bytes per coalesced frame.
- Fewer WINDOW_UPDATES being written and more flow-control bytes returned to remote side more quickly, thereby improving throughput.
