d771526f8c HTTP/2 HelloWorld Client Example Bug
Motivation:
The HTTP/2 helloworld client example has 2 bugs:
1. HttpResponseHandler has a map which is accessed from multiple threads, but the map is not thread safe.
2. Requests are flushed and maybe completely written and the responses may be received/processed by Netty before an element is inserted into the HttpResponseHandler map. This may result in an 'unexpected message' error even though the message has actually been sent.

Modifications:
- HttpResponseHandler should use a thread safe map
- Http2Client shouldn't flush until entries are added to the HttpResponseHandler map

Result:
Fixes https://github.com/netty/netty/issues/6165.

ec3d077e0d DefaultHttp2Connection modifying child map while iterating
Motivation:
When DefaultHttp2Connection removes a stream it iterates over all children and adds them as children to the parent of the stream being removed. This process may remove elements from the child map while iterating without using the iterator's remove() method. This is generally unsafe and may result in an undefined iteration.

Modifications:
- We should use the Iterator's remove() method while iterating over the child map

Result:
Fixes https://github.com/netty/netty/issues/6163

3c5e677964 Add assert to ensure we not create an endless loop and fix unsafe publication
Motivation:

[#6153] reports an endless loop that existed in the Recycler, while this was fixed adding a few asserts to ensure this remains fixed is a good thing. Beside this we also should ensure this can not escape the constructor to avoid unsafe publication.

Modifications:

- Add asserts
- Fix unsafe publication

Result:

More correct code.

631077c793 EPOLL RDHUP processing
Motivation:
EpollRecvByteAllocatorHandle will read unconditionally if EPOLLRDHUP has been received. However we can just treat this the same was we do as data maybe pending in ET mode, and let LT mode notify us if we haven't read all data.

Modifications:
- EpollRecvByteAllocatorHandle should not always force a read just because EPOLLRDHUP has been received, but just treated as an indicator that there maybe more data to read in ET mode

Result:
Fixes https://github.com/netty/netty/issues/6173.

583a59abb1 ByteBufUtil.compare int underflow
Motivation:
ByteBufUtil.compare uses long arithmetic but doesn't check for underflow on when converting from long to int to satisfy the Comparable interface. This will result in incorrect comparisons and violate the Comparable interface contract.

Modifications:
- ByteBufUtil.compare should protect against int underflow

Result:
Fixes https://github.com/netty/netty/issues/6169

2457f386d8 Set prev to null when setting cursor to head in scavengeSome.
Motivation:

`scavengeSome()` has a corner case: when setting `cursor` to `head`, `this.prev` may point to the tail of the  `WeakOrderQueue` linked list. Then it's possible that the following while loop will link the tail to the head, and cause endless loop.

I made a reproducer in 36522e7b72 . The unit test will just run forever. Unfortunately, I cannot change it to a unit test because it needs to add some codes to `scavengeSome` to control the execution flow.

Modification:

Set `prev` to null when setting `cursor` to `head` in `scavengeSome`

Result:

Fixes #6153.

a8950dfc4c InternalThreadLocalMap.arrayList should create a reusable ArrayList only if arrayList field is NULL.
Motivation:

InternalThreadLocalMap.arrayList returns a new ArrayList every time it's called that defeats the purpose of having a reusable ArrayList.

Modification:

Modified InternalThreadLocalMap.arrayList to create an ArrayList only if arrayList field is NULL.

Result:

InternalThreadLocalMap.arrayList now creates a reusable ArrayList only if arrayList field is NULL.

68a941c091 Detecting actual Channel write idleness vs. slowness
Motivation

The IdleStateHandler tracks write() idleness on message granularity but does not take into consideration that the client may be just slow and has managed to consume a subset of the message's bytes in the configured period of time.

Modifications

Adding an optional configuration parameter to IdleStateHandler which tells it to observe ChannelOutboundBuffer's state.

Result

Fixes https://github.com/netty/netty/issues/6150

56ddc47f23 Extends HttpPostRequestEncoder to support all methods except TRACE
Motivation:

In Netty, currently, the HttpPostRequestEncoder only supports POST, PUT, PATCH and OPTIONS, while the RFC 7231 allows with a warning that GET, HEAD, DELETE and CONNECT use a body too (but not TRACE where it is explicitely not allowed).
The RFC in chapter 4.3 says:
"A payload within a XXX request message has no defined semantics;
sending a payload body on a XXX request might cause some existing
implementations to reject the request."
where XXX can be replaced by one of GET, HEAD, DELETE or CONNECT.

Current usages, on particular in REST mode, tend to use those extra HttpMethods for such queries.

So this PR proposes to remove the current restrictions, leaving only TRACE as explicitely not supported.

Modification:

In the constructor, where the test is done, replacing all by checking only against TRACE, and adding one test to check that all methods are supported or not.

Result:

Fixes #6138.

074075de7e Expose channel pool configuration to subclasses.
Motivation:

`SimpleChannelPool` subclasses are likely to override the `connectChannel` method, and are likely to clobber the cloned `Bootstrap` handler in the process. To allow subclasses to properly notify the pool listener of new connections, we should expose (at least) the `handler` property of the pool to subclasses.

Modifications:

Expose `SimpleChannelPool` properties to subclasses via `protected` getters.

Result:

Subclasses can now use the bootstrap, handler, health checker, and health-check-on-release preoperties from their superclass.

28c39a3183 Ensure we use a MPMC queue in ThreadDeathWatcher as it may be used from multiple threads at the same time.
Motivation:

We used a MPSC queue in ThreadDeathWatcher and checked if it empty via isEmpty() from multiple threads if very unlucky. Depending on the implementation this is not safe and may even produce things like live-locks.

Modifications:

Change to use a MPMC queue.

Result:

No more risk to run into issues when multiple threads call watch(...) / unwatch(...) concurrently.

3d11334151 Fix DefaultChannelId MAC address parsing bug
Motivation:
DefaultChannelId provides a regular expression which validates if a user provided MAC address is valid. This regular expression may allow invalid MAC addresses and also not allow valid MAC addresses.

Modifications:
- Introduce a MacAddressUtil#parseMac method which can parse and validate the MAC address at the same time. The regular expression check before hand is additional overhead if we have to parse the MAC address.

Result:
Fixes https://github.com/netty/netty/issues/6132.

3f82b53bae Add unit test for HttpObjectDecoder with message split on buffer boundaries
Motivation:
We should have a unit test which explicitly tests a HTTP message being split between multiple ByteBuf objects.

Modifications:
- Add a unit test to HttpRequestDecoderTest which splits a request between 2 ByteBuf objects

Result:
More unit test coverage for HttpObjectDecoder.

7c630feefc Document and generalize PromiseCombiner
Motivation:

`PromiseCombiner` is really handy, but it's not obvious how to use it from its existing documentation/method signatures.

Modification:

- Added javadoc comments to explain the theory of operation of `PromiseCombiner`.
- Generalized `PromiseCombiner` to work with `Futures` so it's clearer that the things for which it's listening won't be modified.

Result:

`PromiseCombiner` is easier to understand.

16ddf460a6 Added checkStartsWith option for WebSocketServerProtocolHandler
Motivation:

Enables optional .startsWith() matching of req.uri() with websocketPath.

Modifications:

New checkStartsWith boolean option with default false value added to both WebSocketServerProtocolHandler and WebSocketServerProtocolHandshakeHandler. req.uri() matching is based on this option.

Result:

By default old behavior matching via .equal() is preserved. To use checkStartsWith use constructor shortcut: new WebSocketServerProtocolHandler(websocketPath, true) or fill this flag on full form of constructor among other options.

cfd8fb10db [#6134] Do not limit the PID to be <= 4194304
Motivation:

On some platforms the PID my be bigger then 4194304 so we should not limit it to 4194304.

Modifications:

Only check that the PID is a valid Integer

Result:

No more warnings on systems where the PID is bigger then 4194304.

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.

fe2b55cea1 Allow to disable deleting of the native library file after it is loaded.
Motivation:

When profiling it is sometimes needed to still have the native library file avaible. We should allow to disable the explicit deletion and just delete it when the JVM stops.

This is related to #6110

Modifications:

Add io.netty.native.deleteLibAfterLoading system property which allows to disable the explicit delete after laoding

Result:

Possible to profile native libraries better.

cd458f10bc Server returns status 431 on header size errors
Motivation:

Currently clients attempting to send headers that are too large recieve
a RST frame. This makes it harder than needed for implementations on top
of netty to handle this in a graceful way.

Modifications:

When the Decoder throws a StreamError of type FRAME_SIZE_ERROR, the
Http2ConnectionHandler will now attempt to send an Http2Header with
status 431 and endOfStream=true

Result:

Implementations now do not have to subclass parts of netty to handle
431s

89e93968ac Remove usage of own Atomic*FieldUpdater in favor of JDKs
Motivation:

In later Java8 versions our Atomic*FieldUpdater are slower then the JDK implementations so we should not use ours anymore. Even worse the JDK implementations provide for example an optimized version of addAndGet(...) using intrinsics which makes it a lot faster for this use-case.

Modifications:

- Remove methods that return our own Atomic*FieldUpdaters.
- Use the JDK implementations everywhere.

Result:

Faster code.

cb139043f3 [#5831] HttpServerCodec cannot encode a respons e to HEAD
request with a 'content-encoding: chunked' header

Motivation:

It is valid to send a response to a HEAD request that contains a transfer-encoding: chunked header, but it is not valid to include a body, and there is no way to do this using the netty4 HttpServerCodec.

The root cause is that the netty4 HttpObjectEncoder will transition to the state ST_CONTENT_CHUNK and the only way to transition back to ST_INIT is through the encodeChunkedContent method which will write the terminating length (0\r\n\r\n\r\n), a protocol error when responding to a HEAD request

Modifications:

- Keep track of the method of the request and depending on it handle the response differently when encoding it.
- Added a unit test.

Result:

Correclty handle HEAD responses that are chunked.

4639d56596 HttpToHttp2ConnectionHandlerTest increase setup timeout
Motivation:
The 2 second timeout to bootstrap the test can timeout on the build servers. We should increase the timeout so it is less likely under powered or over worked machines are less likely to generate false failures.

Modifications:
- HttpToHttp2ConnectionHandlerTest setup timeout changed from 2 to 5 seconds

Result:
Less false build failures.

712c16ad83 Ensure leak aware buffers correctly close the ResourceLeakTracker
Motivation:

We should assert that the leak aware buffers correctly close the ResourceLeakTracker in the unit tests.

Modifications:

- Keep track of NoopResourceLeakTrackers and check if these were closed once the test completes
- Fix bugs in tests so the buffers are all released.

Result:

Result:

More flexible way to run the tests.

3c92f2b64a Disallow setting logger factory twice
Motivation:

InternalLoggerFactory either sets a default logger factory
implementation based on the logging implementations on the classpath, or
applications can set a logger factory explicitly. If applications wait
too long to set the logger factory, Netty will have already set a logger
factory leading to some objects using one logging implementation and
other objets using another logging implementation. This can happen too
if the application tries to set the logger factory twice, which is
likely a bug in the application. Yet, the Javadocs for
InternalLoggerFactory warn against this saying that
InternalLoggerFactory#setLoggerFactory "should be called as early as
possible and shouldn't be called more than once". Instead, Netty should
guard against this.

Modications:

We replace the logger factory field with an atomic reference on which we
can do CAS operations to safely guard against it being set twice. We
also add an internal holder class that captures the static interface of
InternalLoggerFactory that can aid in testing.

Result:

The logging factory can not be set twice, and applications that want to
set the logging factory must do it before any Netty classes are
initialized (or the default logger factory will be set).

2055f4cf12 Correctly handle the case when BUFFER_OVERFLOW happens during unwrap but the readable bytes are bigger then the expected applicationBufferSize
Motivation:

We need to ensure we handle the case when BUFFER_OVERFLOW happens during unwrap but the readable bytes are bigger then the expected applicationBufferSize. Otherwise we may produce an IllegalArgumentException as we will try to allocate a buffer with capacity < 0.

Modifications:

- Guard against this case.
- Ensure we not double release buffer on exception when doing unwrap.

Result:

No more exception when running testsuite with java 9.

41ea9fa3b6 Ensure SSLErrorTest also works with boringssl
Motivation:

boringssl uses different messages for the ssl alerts which are all uppercase. As we try to match case as well this fails in SSLErrorTest as we expect lower-case.

This test was introduced by 9b7fb2f362.

Modifications:

Ensure we first translate everything to lower-case before doing the assert.

Result:

SSLErrorTest also pass when boringssl is used.

Modifications:
- Restore the logic prior to e102a008b6 which does not automatically close ServerChannels for IOExceptions

Result:
NIO ServerChannel doesn't close automatically for an IOException.

c2f4daa739 Fix false-positives when using ResourceLeakDetector.
Motivation:

We need to ensure the tracked object can not be GC'ed before ResourceLeak.close() is called as otherwise we may get false-positives reported by the ResourceLeakDetector. This can happen as the JIT / GC may be able to figure out that we do not need the tracked object anymore and so already enqueue it for collection before we actually get a chance to close the enclosing ResourceLeak.

Modifications:

- Add ResourceLeakTracker and deprecate the old ResourceLeak
- Fix some javadocs to correctly release buffers.
- Add a unit test for ResourceLeakDetector that shows that ResourceLeakTracker has not the problems.

Result:

No more false-positives reported by ResourceLeakDetector when ResourceLeakDetector.track(...) is used.

7ce0f35b69 Correctly not try to call handshake() when engine is already closed.
Motivation:

We need to ensure we not call handshake() when the engine is already closed. Beside this our implementation of isOutboundDone() was not correct as it not took the pending data in the outbound buffer into acount (which may be also generated as part of an ssl alert). Beside this we also called SSL_shutdown(...) while we were still in init state which will produce an error and so noise in the log with openssl later versions.

This is also in some extend related to #5931 .

Modifications:

- Ensure we not call handshake() when already closed
- Correctly implement isOutboundDone()
- Not call SSL_shutdown(...) when still in init state
- Added test-cases

Result:

More correct behaviour of our openssl SSLEngine implementation.

0ca2c3016b Correct guard against non SSL data in ReferenceCountedOpenSslEngine
Motivation:

When non SSL data is passed into SSLEngine.unwrap(...) we need to throw an SSLException. This was not done at the moment. Even worse we threw an IllegalArgumentException as we tried to allocate a direct buffer with capacity of -1.

Modifications:

- Guard against non SSL data and added an unit test.
- Make code more consistent

Result:

Correct behaving SSLEngine implementation.

f332a00e1a Support compiling netty with Java9
Motivation:

Java9 will be released soon so we should ensure we can compile netty with Java9 and run all our tests. This will help to make sure Netty will be usable with Java9.

Modification:

- Add some workarounds to be able to compile with Java9, note that the full profile is not supported with Java9 atm.
- Remove some usage of internal APIs to be able to compile on java9
- Not support Alpn / Npn and so not run the tests when using Java9 for now. We will do a follow up PR to add support.

Result:

Its possible to build netty and run its testsuite with Java9.
