4d6ab1d30d Fix missing trailing data on HTTP client upgrade
Motivation:

When HttpClientUpgradeHandler upgrades from HTTP/1 to another protocol,
it performs a two-step opertion:

1. Remove the SourceCodec (HttpClientCodec)
2. Add the UpgradeCodec

When HttpClientCodec is removed from the pipeline, the decoder being
removed triggers channelRead() event with the data left in its
cumulation buffer. However, this is not received by the UpgradeCodec
becuase it's not added yet. e.g. HTTP/2 SETTINGS frame sent by the
server can be missed out.

To fix the problem, we need to reverse the steps:

1. Add the UpgradeCodec
2. Remove the SourceCodec

However, this does not work as expected either, because UpgradeCodec can
send a greeting message such as HTTP/2 Preface. Such a greeting message
will be handled by the SourceCodec and will trigger an 'unsupported
message type' exception.

To fix the problem really, we need to make the upgrade process 3-step:

1. Remove/disable the encoder of SourceCodec
2. Add the UpgradeCodec
3. Remove the SourceCodec

Modifications:

- Add SourceCodec.prepareUpgradeFrom() so that SourceCodec can remove or
  disable its encoder
- Implement HttpClientCodec.prepareUpgradeFrom() properly
- Miscellaneous:
  - Log the related channel as well When logging the failure to send a
    GOAWAY

Result:

Cleartext HTTP/1-to-HTTP/2 upgrade works again.

11bcb8790c Http2Connection stream id generation to support queueing
Motivation:
StreamBufferingEncoder provides queueing so that MAX_CONCURRENT_STREAMS is not violated. However the stream id generation provided by Http2Connection.nextStreamId() only returns the next stream id that is expected on the connection and does not account for queueing. The codec should provide a way to generate the next stream id for a given endpoint that functions with or without queueing.

Modifications:
- Change Http2Connection.nextStreamId to Http2Connection.incrementAndGetNextStreamId

Result:
Http2Connection can generate the next stream id in queued and non-queued scenarios.

78b508a7eb AbstractHttp2ConnectionHandlerBuilder validateHeaders cannot be set with encoder/decoder
Motivation:
If validateHeaders is set in combination with the encoder/decoder it will be silently ignored. We should enforce the constraint that validateHeaders and encoder/decoder are mutually exclusive.

Modifications:
- Make sure either validateHeaders can be set or encoder/decoder.

Result:
AbstractHttp2ConnectionHandlerBuilder does not allow conflicting options to be set.

e8850072e2 HTTP/2 DefaultHttp2RemoteFlowController frame merging with padding bug
Motivation:
DefaultHttp2RemoteFlowController does not correctly account for the padding in the event frames are merged. This causes the internal stat of DefaultHttp2RemoteFlowController to become corrupt and can result in attempting to write frames when there are none.

Modifications:
- Update DefaultHttp2RemoteFlowController to account for frame sizes not necessarily adding together.

Result:
DefaultHttp2RemoteFlowController internal state does not become corrupt when padding is present.

Motivation:
Currently it's impossible to distinguish which
connection the corresponding logged message	is
related to.

Modifications:

7dba13f276 HttpConversionUtil remove throws from method signature
Motivation:
HttpConversionUtil.toHttp2Headers currently has a throws Exception as part of the signature. This comes from the signature of ByteProcessor.process, but is not necessary because the ByteProcessor used does not throw.

Modifications:
- Remove throws Exception from the signature of HttpConversionUtil.toHttp2Headers.

Result:
HttpConversionUtil.toHttp2Headers interface does not propagate a throws Exception when it is used.

Motivation:
If the stream window is negative UniformStreamByteDistributor may write data. This is prohibited by the RFC https://tools.ietf.org/html/rfc7540#section-6.9.2.

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

6257091d12 HttpConversionUtil does not account for COOKIE compression
Motivation:
The HTTP/2 RFC allows for COOKIE values to be split into individual header elements to get more benefit from compression (https://tools.ietf.org/html/rfc7540#section-8.1.2.5). HttpConversionUtil was not accounting for this behavior.

Modifications:
- Modify HttpConversionUtil to support compressing and decompressing the COOKIE values

Result:
HttpConversionUtil is compatible with https://tools.ietf.org/html/rfc7540#section-8.1.2.5)

8cd259896e No HTTP/2 RST_STREAM if no prior HEADERS were sent
Motivation:

Because we flow control HEADERS frames, it's possible that an intermediate error can result in a RST_STREAM frame being sent for a frame that the other endpoint is not yet aware of. This is a violation of the spec and will either result in spammy logs at the other endpoint or broken connections.

Modifications:

Modified the HTTP/2 handler so that it only sends RST_STREAM if it has sent at least one HEADERS frame to the remote endpoint for the stream.

Result:

Fixes #4465

dbaeb3314e Allow HTTP2 frame writer to accept arbitrarily large frames
Motivation:

The encoder is currently responsible for chunking frames when writing in order to conform to max frame size. The frame writer would be a better place for this since it could perform a reuse the same promise aggregator for all the write and could also perform a single allocation for all of the frame headers.

Modifications:

Modified `DefaultHttp2FrameWriter` to perform the chunking and modified the contract in the `Http2FrameWriter` interface. Modified `DefaultHttp2ConnectionEncoder` to send give all allocated bytes to the writer.

Result:

79ab756fa3 Use a single queue in UniformStreamByteDistributor
Motivation:

The UniformStreamByteDistributor currently processes all zero-length frames, regardless of add order. This means that we would always send HEADERS for all streams, possibly taking away bandwidth for streams that actually have data.

Modifications:

Empty frames are now treated the same as any other frame except that the algorithm will pop off the any empty frames at the head of the queue.

Result:

Empty frames require no extra processing.

cfcee5798d Adjustable size of DefaultHeaders array
Motivation:
DefaultHeaders creates an array of size 16 for all headers. This may waste a good deal of memory if applications only have a small number of headers. This memory may be critical when the number of connections grows large.

Modifications:
- Make the size of the array for DefaultHeaders configurable

Result:
Applications can control the size of the DefaultHeaders array and save memory.

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.

96f9b0b91b Remote flow controller incorrectly updates stream state
Motivation:

The `DefaultHttp2RemoteFlowController` does not correctly determine `hasFrame` when updating the stream state for the distributor. Adding a check to enforce `hasFrame` when `streamableBytes > 0` causes several test failures.

Modifications:

Modified `DefaultHttp2RemoteFlowController` to simplify the writing logic and to correct the bookkeeping for `hasFrame`.

Result:

The distributors are always called with valid arguments.

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.

91b8ef3d10 HTTP/2 PriorityStreamByteDistributor exceptions and reentry
Motivation:
PriorityStreamByteDistributor saves exception state and attempts to reset state. This could be simplified by just throwing a connection error and closing the connection. PriorityStreamByteDistributor also does not handle or detect re-entry in the distribute method.

Motivation:
- PriorityStreamByteDistributor propagate an INTERNAL_ERROR if an exception occurs during writing
- PriorityStreamByteDistributor to handle re-entry on the write method

Result:
PriorityStreamByteDistributor exception code state simplified, and re-entry is detected.

Motivation:

Http2ConnectionHandler verifies if the first frame after the preface is
a SETTINGS frame.  However, it does not reject the SETTING ack frame
which is not expected actually.

Modifications:

Reject a SETTINGS-ack frame as well

Result:

When the first frame is a SETTINGS-ack frame, connection does not
proceed to further frame handling. (simplicity)

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.

Motivation:
Http2ConnectionHandler.BaseBuilder is constructing objects which have 'close' methods, but is not calling these methods in the event of an exception.

06c3ae07a0 DefaultHttp2ConnectionDecoder write ping buffer
Motivation:
DefaultHttp2ConnectionDecoder writes a ACK when receiving a ping frame and sends the same data buffer it received. The data buffer is also passed to the listener, but the indexes are shared between the send and the listener. We should ensure the indexes are independent for these two operations.

Modifications:
- Call slice on the buffer that is being sent

Result:
Listener now has access to a buffer that will not appear to be already consumed.

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.

93011dd315 DefaultHttp2RemoteFlowController not allocating all available bytes
Motivation:
DefaultHttp2RemoteFlowController's allocation algorithm may not allocate all bytes that are available in the connection window. If the 'fair share' based upon weight is not fully used by sibling nodes it was not correctly re-distributed to other sibilings which may be able to utilize part / all of that share.

Modifications:
- Add a unit test which demonstrates the issue.
- Modify the allocation algorithm to ensure all available bytes are allocated.

Modifications:
- Remove AUTHORITY extension header
- HTTP/2 :authority should map to HOST header when converting to HTTP/1.x.
