3344cd21ac Wrap operations requiring SocketPermission with doPrivileged blocks
Motivation:

Currently Netty does not wrap socket connect, bind, or accept
operations in doPrivileged blocks. Nor does it wrap cases where a dns
lookup might happen.

This prevents an application utilizing the SecurityManager from
isolating SocketPermissions to Netty.

Modifications:

I have introduced a class (SocketUtils) that wraps operations
requiring SocketPermissions in doPrivileged blocks.

Result:

A user of Netty can grant SocketPermissions explicitly to the Netty
jar, without granting it to the rest of their application.

2fd42cfc6b HTTP/2 Max Header List Size Bug
Motivation:
If the HPACK Decoder detects that SETTINGS_MAX_HEADER_LIST_SIZE has been violated it aborts immediately and sends a RST_STREAM frame for what ever stream caused the issue. Because HPACK is stateful this means that the HPACK state may become out of sync between peers, and the issue won't be detected until the next headers frame. We should make a best effort to keep processing to keep the HPACK state in sync with our peer, or completely close the connection.
If the HPACK Encoder is configured to verify SETTINGS_MAX_HEADER_LIST_SIZE it checks the limit and encodes at the same time. This may result in modifying the HPACK local state but not sending the headers to the peer if SETTINGS_MAX_HEADER_LIST_SIZE is violated. This will also lead to an inconsistency in HPACK state that will be flagged at some later time.

Modifications:
- HPACK Decoder now has 2 levels of limits related to SETTINGS_MAX_HEADER_LIST_SIZE. The first will attempt to keep processing data and send a RST_STREAM after all data is processed. The second will send a GO_AWAY and close the entire connection.
- When the HPACK Encoder enforces SETTINGS_MAX_HEADER_LIST_SIZE it should not modify the HPACK state until the size has been checked.
- https://tools.ietf.org/html/rfc7540#section-6.5.2 states that the initial value of SETTINGS_MAX_HEADER_LIST_SIZE is "unlimited". We currently use 8k as a limit. We should honor the specifications default value so we don't unintentionally close a connection before the remote peer is aware of the local settings.
- Remove unnecessary object allocation in DefaultHttp2HeadersDecoder and DefaultHttp2HeadersEncoder.

Result:
Fixes https://github.com/netty/netty/issues/6209.

b701da8d1c HTTP/2 HPACK Integer Encoding Bugs
Motivation:
- Decoder#decodeULE128 has a bounds bug and cannot decode Integer.MAX_VALUE
- Decoder#decodeULE128 doesn't support values greater than can be represented with Java's int data type. This is a problem because there are cases that require at least unsigned 32 bits (max header table size).
- Decoder#decodeULE128 treats overflowing the data type and invalid input the same. This can be misleading when inspecting the error that is thrown.
- Encoder#encodeInteger doesn't support values greater than can be represented with Java's int data type. This is a problem because there are cases that require at least unsigned 32 bits (max header table size).

Modifications:
- Correct the above issues and add unit tests.

Result:
Fixes https://github.com/netty/netty/issues/6210.

06e7627b5f Read Only Http2Headers
Motivation:
A read only implementation of Http2Headers can allow for a more efficient usage of memory and more performant combined construction and iteration during serialization.

Modifications:
- Add a new ReadOnlyHttp2Headers class

Result:
ReadOnlyHttp2Headers exists and can be used for performance reasons when appropriate.

edc4842309 Fix cookie date parsing, close #6016
Motivation:
* RFC6265 defines its own parser which is different from RFC1123 (it accepts RFC1123 format but also other ones). Basically, it's very lax on delimiters, ignores day of week and timezone. Currently, ClientCookieDecoder uses HttpHeaderDateFormat underneath, and can't parse valid cookies such as Github ones whose expires attribute looks like "Sun, 27 Nov 2016 19:37:15 -0000"
* ServerSideCookieEncoder currently uses HttpHeaderDateFormat underneath for formatting expires field, and it's slow.

Modifications:
* Introduce HttpHeaderDateFormatter that correctly implement RFC6265
* Use HttpHeaderDateFormatter in ClientCookieDecoder and ServerCookieEncoder
* Deprecate HttpHeaderDateFormat

Result:
* Proper RFC6265 dates support
* Faster ServerCookieEncoder and ClientCookieDecoder
* Faster tool for handling headers such as "Expires" and "Date"

c9918de37b http2: Make MAX_HEADER_LIST_SIZE exceeded a stream error when encoding.
Motivation:

The SETTINGS_MAX_HEADER_LIST_SIZE limit, as enforced by the HPACK Encoder, should be a stream error and not apply to the whole connection.

Modifications:

Made the necessary changes for the exception to be of type StreamException.

Result:

A HEADERS frame exceeding the limit, only affects a specific stream.

540c26bb56 HTTP/2 Ensure default settings are correctly enforced and interfaces clarified
Motivation:
The responsibility for retaining the settings values and enforcing the settings constraints is spread out in different areas of the code and may be initialized with different values than the default specified in the RFC. This should not be allowed by default and interfaces which are responsible for maintaining/enforcing settings state should clearly indicate the restrictions that they should only be set by the codec upon receipt of a SETTINGS ACK frame.

Modifications:
- Encoder, Decoder, and the Headers Encoder/Decoder no longer expose public constructors that allow the default settings to be changed.
- Http2HeadersDecoder#maxHeaderSize() exists to provide some bound when headers/continuation frames are being aggregated. However this is roughly the same as SETTINGS_MAX_HEADER_LIST_SIZE (besides the 32 byte octet for each header field) and can be used instead of attempting to keep the two independent values in sync.
- Encoding headers now enforces SETTINGS_MAX_HEADER_LIST_SIZE at the octect level. Previously the header encoder compared the number of header key/value pairs against SETTINGS_MAX_HEADER_LIST_SIZE instead of the number of octets (plus 32 bytes overhead).
- DefaultHttp2ConnectionDecoder#onData calls shouldIgnoreHeadersOrDataFrame but may swallow exceptions from this method. This means a STREAM_RST frame may not be sent when it should for an unknown stream and thus violate the RFC. The exception is no longer swallowed.

Result:
Default settings state is enforced and interfaces related to settings state are clarified.

67d3a78123 Reduce bytecode size of PlatformDependent0.equals.
Motivation:

PP0.equals has a bytecode size of 476. This is above the default inlining threshold of OpenJDK.

Modifications:

Slightly change the method to reduce the bytecode size by > 50% to 212 bytes.

Result:

The bytecode size is dramatically reduced, making the method a candidate for inlining.
The relevant code in our application (gRPC) that relies heavily on equals comparisons,
runs some ~10% faster. The Netty JMH benchmark shows no performance regression.

Current 4.1:

PlatformDependentBenchmark.unsafeBytesEqual      10  avgt   20     7.836 ±   0.113  ns/op
PlatformDependentBenchmark.unsafeBytesEqual      50  avgt   20    16.889 ±   4.284  ns/op
PlatformDependentBenchmark.unsafeBytesEqual     100  avgt   20    15.601 ±   0.296  ns/op
PlatformDependentBenchmark.unsafeBytesEqual    1000  avgt   20    95.885 ±   1.992  ns/op
PlatformDependentBenchmark.unsafeBytesEqual   10000  avgt   20   824.429 ±  12.792  ns/op
PlatformDependentBenchmark.unsafeBytesEqual  100000  avgt   20  8907.035 ± 177.844  ns/op

With this change:

PlatformDependentBenchmark.unsafeBytesEqual      10  avgt   20      5.616 ±   0.102  ns/op
PlatformDependentBenchmark.unsafeBytesEqual      50  avgt   20     17.896 ±   0.373  ns/op
PlatformDependentBenchmark.unsafeBytesEqual     100  avgt   20     14.952 ±   0.210  ns/op
PlatformDependentBenchmark.unsafeBytesEqual    1000  avgt   20     94.799 ±   1.604  ns/op
PlatformDependentBenchmark.unsafeBytesEqual   10000  avgt   20    834.996 ±  17.484  ns/op
PlatformDependentBenchmark.unsafeBytesEqual  100000  avgt   20   8757.421 ± 187.555  ns/op

208893aac9 HTTP/2 Hpack Encoder Cleanup
Motivation:
The HTTP/2 HPACK Encoder class has some code which is only used for test purposes. This code can be removed to reduce complexity and member variable count.

Modifications:
- Remove test code and update unit tests
- Other minor cleanup

Result:
Test code is removed from operational code.

21e8d84b79 HTTP/2 Simplify Headers Decode Bounds Checking
Motivation:
The HPACK decoder keeps state so that the decode method can be called multiple times with successive header fragments. This decoder also requires that a method is called to signify the decoding is complete. At this point status is returned to indicate if the max header size has been violated. Netty always accumulates the header fragments into a single buffer before attempting to HPACK decode process and so keeping state and delaying notification that bounds have been exceeded is not necessary.

Modifications:
- HPACK Decoder#decode(..) now must be called with a complete header block
- HPACK will terminate immediately if the maximum header length, or maximum number of headers is exceeded
- Reduce member variables in the HPACK Decoder class because they can now live in the decode(..) method

Result:
HPACK bounds checking is done earlier and less class state is needed.

82b617dfe9 retainSlice() unwrap ByteBuf
Motivation:
retainSlice() currently does not unwrap the ByteBuf when creating the ByteBuf wrapper. This effectivley forms a linked list of ByteBuf when it is only necessary to maintain a reference to the unwrapped ByteBuf.

Modifications:
- retainSlice() and retainDuplicate() variants should only maintain a reference to the unwrapped ByteBuf
- create new unit tests which generally verify the retainSlice() behavior
- Remove unecessary generic arguments from AbstractPooledDerivedByteBuf
- Remove unecessary int length member variable from the unpooled sliced ByteBuf implementation
- Rename the unpooled sliced/derived ByteBuf to include Unpooled in their name to be more consistent with the Pooled variants

Result:

6af56ffe76 HPACK Encoder headerFields improvements
Motivation:
HPACK Encoder has a data structure which is similar to a previous version of DefaultHeaders. Some of the same improvements can be made.

Motivation:
- Enforce the restriction that the Encoder's headerFields length must be a power of two so we can use masking instead of modulo
- Use AsciiString.hashCode which already has optimizations instead of having yet another hash code algorithm in Encoder

Result:
Fixes https://github.com/netty/netty/issues/5357

a7f7d9c8e0 Remove unsafe char[] access in PlatformDependent
Motivation:
PlatformDependent attempts to use reflection to get the underlying char[] (or byte[]) from String objects. This is fragile as if the String implementation does not utilize the full array, and instead uses a subset of the array, this optimization is invalid. OpenJDK6 and some earlier versions of OpenJDK7 String have the capability to use a subsection of the underlying char[].

Modifications:
- PlatformDependent should not attempt to use the underlying array from String (or other data types) via reflection

Result:
PlatformDependent hash code generation for CharSequence does not depend upon specific JDK implementation details.

70651cc58d HpackUtil.equals performance improvement
Motivation:
PR #5355 modified interfaces to reduce GC related to the HPACK code. However this came with an anticipated performance regression related to HpackUtil.equals due to AsciiString's increase cost of charAt(..). We should mitigate this performance regression.

Modifications:
- Introduce an equals method in PlatformDependent which doesn't leak timing information and use this in HpcakUtil.equals

b4d4c0034d Optimize HPACK usage to align more with Netty types and remove heavy object creations. Related to [#3597]
Motivations:

The HPACK code was not really optimized and written with Netty types in mind. Because of this a lot of garbage was created due heavy object creation.

This was first reported in [#3597] and https://github.com/grpc/grpc-java/issues/1872 .

Modifications:

- Directly use ByteBuf as input and output
- Make use of ByteProcessor where possible
- Use AsciiString as this is the only thing we need for our http2 usage

Result:

Less garbage and better usage of Netty apis.

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.

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.

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

9229ed98e2 [#5088] Add annotation which marks packages/interfaces/classes as unstable
Motivation:

Some codecs should be considered unstable as these are relative new. For this purpose we should introduce an annotation which these codecs should us to be marked as unstable in terms of API.

Modifications:

- Add UnstableApi annotation and use it on codecs that are not stable
- Move http2.hpack to http2.internal.hpack as it is internal.
