501662a77f Use long for http2 ping payload.
Motivation:

At the moment we use a ByteBuf as the payload for a http2 frame. This complicates life-time management a lot with no real gain and also may produce more objects then needed. We should just use a long as it is required to be 8 bytes anyway.

Modifications:

Use long for ping payloads.

Result:

Fixes [#7629].

50a067a8f7 Make methods 'static' where it possible
Motivation:

Even if it's a super micro-optimization (most JVM could optimize such
 cases in runtime), in theory (and according to some perf tests) it
 may help a bit. It also makes a code more clear and allows you to
 access such methods in the test scope directly, without instance of
 the class.

Modifications:

Add 'static' modifier for all methods, where it possible. Mostly in
test scope.

Result:

Cleaner code with proper 'static' modifiers.

4875a2aad4 Immediate caching the strings wrapped to AsciiString
Motivation:
The `AsciiString#toString` method calculate string value and cache it into field. If an `AsciiString` created from the `String` value, we can avoid rebuilding strings if we cache them immediately when creating `AsciiString`. It would be useful for constants strings, which already stored in the JVMs string table, or in cases where an unavoidable `#toString `method call is assumed.

Modifications:
- Add new static method `AsciiString#cache(String)` which save string value into cache field.
- Apply a "benign" data race in the `#hashCode` and `#toString` methods.

Result:
Less memory usage in some `AsciiString` use cases.

74f24a5c19 Finish work on http2 child channel implementation and http2 frame api.
Motivation:

Our http2 child channel implementation was not 100 % complete and had a few bugs. Beside this the performance overhead was non-trivial.

Modifications:

There are a lot of modifications, the most important....
  * Http2FrameCodec extends Http2ConnectionHandler and Http2MultiplexCodec extends Http2FrameCodec to reduce performance heads and inter-dependencies on handlers in the pipeline
  * Correctly handle outbound flow control for child channels
  * Support unknow frame types in Http2FrameCodec and Http2MultiplexCodec
  * Use a consistent way how to create Http2ConnectionHandler, Http2FrameCodec and Http2MultiplexCodec (via a builder)
  * Remove Http2Codec and Http2CodecBuilder as the user should just use Http2MultipleCodec and Http2MultiplexCodecBuilder now
  * Smart handling of flushes from child channels to reduce overhead
  * Reduce object allocations
  * child channels always use the same EventLoop as the parent Channel to reduce overhead and simplify implementation.
  * Not extend AbstractChannel for the child channel implementation to reduce overhead in terms of performance and memory usage
  * Remove Http2FrameStream.managedState(...) as the user of the child channel api should just use Channel.attr(...)

Result:

Http2MultiplexCodec (and so child channels) and Http2FrameCodec are more correct, faster and more feature complete.

5380c7c3e3 HTTP/2 Child Channel and FrameCodec Feature Parity.
Motivation:

This PR (unfortunately) does 4 things:
1) Add outbound flow control to the Http2MultiplexCodec:
   The HTTP/2 child channel API should interact with HTTP/2 outbound/remote flow control. That is,
   if a H2 stream used up all its flow control window, the corresponding child channel should be
   marked unwritable and a writability-changed event should be fired. Similarly, a unwritable
   child channel should be marked writable and a writability-event should be fired, once a
   WINDOW_UPDATE frame has been received. The changes are (mostly) contained in ChannelOutboundBuffer,
   AbstractHttp2StreamChannel and Http2MultiplexCodec.

2) Introduce a Http2Stream2 object, that is used instead of stream identifiers on stream frames. A
   Http2Stream2 object allows an application to attach state to it, and so a application handler
   no longer needs to maintain stream state (i.e. in a map(id -> state)) himself.

3) Remove stream state events, which are no longer necessary due to the introduction of Http2Stream2.
   Also those stream state events have been found hard and complex to work with, when porting gRPC
   to the Http2FrameCodec.

4) Add support for HTTP/2 frames that have not yet been implemented, like PING and SETTINGS. Also add
   a Http2FrameCodecBuilder that exposes options from the Http2ConnectionHandler API that couldn't else
   be used with the frame codec, like buffering outbound streams, window update ratio, frame logger, etc.

Modifications:

1) A child channel's writability and a H2 stream's outbound flow control window interact, as described
   in the motivation. A channel handler is free to ignore the channel's writability, in which case the
   parent channel is reponsible for buffering writes until a WINDOW_UPDATE is received.

   The connection-level flow control window is ignored for now. That is, a child channel's writability
   is only affected by the stream-level flow control window. So a child channel could be marked writable,
   even though the connection-level flow control window is zero.

2) Modify Http2StreamFrame and the Http2FrameCodec to take a Http2Stream2 object intstead of a primitive
   integer. Introduce a special Http2ChannelDuplexHandler that has newStream() and forEachActiveStream()
   methods. It's recommended for a user to extend from this handler, to use those advanced features.

3) As explained in the documentation, a new inbound stream active can be detected by checking if the
   Http2Stream2.managedState() of a Http2HeadersFrame is null. An outbound stream active can be detected
   by adding a listener to the ChannelPromise of the write of the first Http2HeadersFrame. A stream
   closed event can be listened to by adding a listener to the Http2Stream2.closeFuture().

4) Add a simple Http2FrameCodecBuilder and implement the missing frame types.

Result:

1) The Http2MultiplexCodec supports outbound flow control.
2) The Http2FrameCodec API makes it easy for a user to manage custom stream specific state and to create
   new outbound streams.
3) The Http2FrameCodec API is much cleaner and easier to work with. Hacks like the ChannelCarryingHeadersFrame
   are no longer necessary.
4) The Http2FrameCodec now also supports PING and SETTINGS frames. The Http2FrameCodecBuilder allows the Http2FrameCodec
   to use some of the rich features of the Http2ConnectionHandler API.

580ac8cd41 Only flush on channelReadComplete(...) in http2 hello world examples.
Motivation:

In our http1 hello world example we only flush on channelReadComplete(...) to make better use of gathering writes. We should do the same in http2.

Modifications:

Only flush in channelReadComplete(...)

Result:

Better performance and more consistent examples.

6b25909f6b HTTP/2 HelloWorld clear text NPE
Motivation:
HelloWorldHttp2Handler throws a NPE when converting from HTTP/1.x headers to HTTP/2 headers because there is no Host header.

Modifications:
- HelloWorldHttp2Handler should check if the Host header is present before setting it in the HTTP/2 headers

Result:
No more NPE in HelloWorldHttp2Handler.

cf26227c6c Supply a builder for Http2Codec
Motivation:

DefaultHttp2FrameWriter has constructors that it would be a hassle to
expose as configuration parameters on Http2Codec. We should instead
make a builder for Http2Codec.

Modifications:

Get rid of the public constructors on Http2Codec and instead make sure
you can always use the builder where you would have used the constructor
before.

Result:

Http2Codec can be configured more flexibly, and the SensitivityDetector
can be configured.

92efa3c916 Add UptimeServer and adjust UptimeClient's code style.
Motivation:

Uptime example is lack of server.
UptimeClient's code style is a little bit different from others, which make reader feel confused.
We don't need to create a new Bootstrap instance each time client reconnect to server.

Modification:

Add UptimeServer and UptimeServerHandler which simply accept all connection and discard all message.
Change UptimeClient's code style.
Share a single Bootstrap instance.

Result:

Uptime server support.
Consistent code style.
Single Bootstrap for all reconnection.

b1cb059540 Motivation:
It is generally useful to have origin http servers respond to
"expect: continue-100" as soon as possible but applications without a
HttpObjectAggregator in their pipelines must use boiler plate to do so.

Modifications:

Introduce the HttpServerExpectContinueHandler handler to make it easier.

Result:

Less boiler plate for http application authors.

38483e8790 Correctly manage buffer life-cycle in http2 multiplex example
Motivation:

We not correctly managed the life-cycle of the buffer / frames in our http2 multiplex example which lead to a memory leak.

Modifications:

- Correctly release frame if not echo'ed back the remote peer.
- Not retain content before echo back to remote peer.

Result:

No more leak in the example, fixes [#6636].

077a1988b9 OCSP stapling support for Netty using netty-tcnative.
https://github.com/netty/netty-tcnative/pull/215

Motivation

OCSP stapling (formally known as TLS Certificate Status Request extension) is alternative approach for checking the revocation status of X.509 Certificates. Servers can preemptively fetch the OCSP response from the CA's responder, cache it for some period of time, and pass it along during (a.k.a. staple) the TLS handshake. The client no longer has to reach out on its own to the CA to check the validity of a cetitficate. Some of the key benefits are:

1) Speed. The client doesn't have to crosscheck the certificate.
2) Efficiency. The Internet is no longer DDoS'ing the CA's OCSP responder servers.
3) Safety. Less operational dependence on the CA. Certificate owners can sustain short CA outages.
4) Privacy. The CA can lo longer track the users of a certificate.

0ee36fef00 Accept two ways to start HTTP/2 over clear text
Motivation:

HTTP/2 support two ways to start on a no-tls tcp connection,
http/1.1 upgrade and prior knowlege methodology to start HTTP/2.
Currently, the http2-server from example only support
starting by upgrade. I think we can do a simple dispatch by peek first
bytes from inbound that match to prior knowledge preface or not and
determine which handlers to set into pipeline.

Modifications:

Add ClearTextHttp2ServerUpgradeHandler to support start HTTP/2 via clear
text with two approach. And update example/http2-server to support
this functionality.

Result:

netty HTTP/2 and the example http2-server accept for two ways to start
HTTP/2 over clear text.

Fixed memory leak problem

Update fields to final

Rename ClearText to cleartext

Addressed comments for code improvement

- Always prefer static, final, and private if possible
- Add UnstableApi annotation
- Used EmbeddedChannel.readInbound instead of unhandled inbound handler
- More assertion

Update javadoc for CleartextHttp2ServerUpgradeHandler

Rename ClearTextHttp2ServerUpgradeHandler to CleartextHttp2ServerUpgradeHandler

Removed redundant code about configure pipeline

nit: PriorKnowledgeHandler

Removed Mockito.spy, investigate conn state instead

Add Http2UpgradeEvent

Check null of the constructor arguments

Rename Http2UpgradeEvent to PriorKnowledgeUpgradeEvent

Update unit test

1419f5b601 Adding support for Conscrypt (#6271)
Motivation:

Conscrypt is a Java Security provider that wraps OpenSSL (specifically BoringSSL). It's a possible alternative to Netty-tcnative that we should explore. So this commit is just to enable us to further investigate its use.

Modifications:

Modifying the SslContext creation path to support the Conscrypt provider.

Result:

Netty will support OpenSSL with conscrypt.
