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.

8adb30bbe2 Correctly run all pending tasks for EmbeddedChannel when the Channel was closed.
Motivation:

When a user called ctx.close() and used the EmbeddedChannel we did not correctly run all pending tasks which means channelInactive was never called.

Modifications:

Ensure we run all pending tasks after all operations that may change the Channel state and are part of the Channel.Unsafe impl.

Result:

Fixes [#6894].

c5b5d36360 Fix false-positive leak detection report when ReferenceCountedOpenSslEngine constructor throws.
Motivation:

We need to ensure we only create the ResourceLeak when the constructor not throws.

Modifications:

Ensure ResourceLeakDetector.track(...) is only called if the constructor of ReferenceCoundedOpenSslEngine not throws.

Result:

No more false-positves.

60250f3795 Make DelegatingChannelPromiseNotifier use Vararg overload
Motivation:
ErrorProne complains that the array override doesn't match the
vararg super call.  See http://errorprone.info/bugpattern/Overrides

Additionally, almost every other Future uses the vararg form, so
it would be stylistically consistent to keep it that way.

Modifications:
Use vararg override.

Result:
Cleaner, less naggy code.

732b145842 Http2ConnectionHandler: allow graceful shutdown to wait forever
Motivation:

There should be a way to allow graceful shutdown to wait for all open streams to close without a timeout. Using gracefulShutdownTimeoutMillis with a large value is a bit of a hack, and has a gotcha that sufficiently large values will overflow the long, resulting in a ClosingChannelFutureListener that executes immediately.

Modification:

Allow to use gracefulShutdownTimeoutMillis(-1) to express waiting until all streams are closed.

Result:

We can now shutdown the connection without a forced timeout.

529025d9d5 Allow to use oldest Channel out of the Simple / FixedChannelPool on acquire
Motivation:

We previously used pollLast() to retrieve a Channel from the queue that backs SimpleChannelPool. This could lead to the problem that some Channels are very unfrequently used and so when these are used the connection was already be closed and so could not be reused.

Modifications:

Allow to configure if the last recent used Channel should be used or the "oldest".

Result:

More flexible usage of ChannelPools

359beff56f Choose ipv4 or ipv6 google dns servers as default fallback based on the settings for this system / jvm
Motivation:

We should not use ipv4 google dns servers if the app is configured to run ipv6.

Modifications:

Use either ipv4 or ipv6 dns servers depending on the system config.

Result:

efb2d141c1 Correctly handle unsigned int values returned from TCP_INFO
Motivation:

We used an int[] to store all values that are returned in the struct for TCP_INFO which is not good enough as it uses usigned int values.

Modifications:

- Change int[] to long[] and correctly cast values.

Result:

No more truncated values.

34fdc7a33e Skip invalid hostnames when construct default dns servers to use.
Motivation:

When the hostname portion can not be extracted we should just skip the server as otherwise we will produce and exception when trying to create the InetSocketAddress.

This was happing when trying to run the test-suite on a system and using java7:

java.lang.IllegalArgumentException: hostname can't be null
	at java.net.InetSocketAddress.checkHost(InetSocketAddress.java:149)
	at java.net.InetSocketAddress.<init>(InetSocketAddress.java:216)
	at io.netty.util.internal.SocketUtils$10.run(SocketUtils.java:171)

d8f4547f5c Unify {Epoll,KQueue}EventLoopGroup initialization.
Motivation:
`Epoll.ensureAvailability()` is called multiple times, once in
static initialization and in a couple of the constructors.  This is
redundant and confusing to read.

Modifications:
Move `Epoll.ensureAvailability()` call into an instance initializer
and remove all other references.  This ensures that every EELG
checks availability, while still delaying the check until
construction.  This pattern is used when there are multiple ctors,
as in this class.

Result:
Easier to read code.

452fd36240 ByteBufs which are not resizable should not throw in ensureWritable(int,boolean)
Motivation:
ByteBuf#ensureWritable(int,boolean) returns an int indicating the status of the resize operation. For buffers that are unmodifiable or cannot be resized this method shouldn't throw but just return 1.
ByteBuf#ensureWriteable(int) should throw unmodifiable buffers.

Modifications:
- ReadOnlyByteBuf should be updated as described above.
- Add a unit test to SslHandler which verifies the read only buffer can be tolerated in the aggregation algorithm.

Result:
Fixes https://github.com/netty/netty/issues/7002.

2fbce6d470 Delete temporary self-signed certs in SSLEngineTest-based tests
Motivation:

Lots of usages of SelfSignedCertificates were not deleting the certs at
the end of the test. This includes setupHandlers() which is used by
extending classes. Although these files will be deleted at JVM exit and
deleting them early does not free the JVM from trying to delete them at
shutdown, it's good practice to delete eagerly and since users sometimes
use tests as a form of documentation, it'd be good for them to see the
explicit deletes.

Modifications:

Add missing delete() calls to ½ of the SelfSignedCertificates-using
tests.

Result:

Tests that more clearly communicates which resources are created and
may accumulate without early delete.

8a25c35939 Filter user-provided ciphers using RFC cipher names
Motivation:

Previously filterCipherSuites was being passed the OpenSSL-formatted
cipher names. Commit 43ae974 introduced a regression as it swapped to the
RFC/JDK format, except that user-provided ciphers were not converted and
remained in the OpenSSL format.

This mis-match would cause all user-provided to be thrown away, leading
to failure trying to set zero ciphers:
Exception in thread "main" javax.net.ssl.SSLException: failed to set cipher suite: []
	at io.netty.handler.ssl.ReferenceCountedOpenSslContext.<init>(ReferenceCountedOpenSslContext.java:299)

	at io.netty.handler.ssl.ReferenceCountedOpenSslContext.<init>(ReferenceCountedOpenSslContext.java:295)
	... 7 more

Modifications:

Remove the reformatting of user-provided ciphers, as they are already in
the RFC/JDK format.

Result:

No regression, and the internals stay sane using the RFC/JDK format.

3cdff36821 Update tests to not use TestUtils.getFreePort() and so ensure we not try to use a port that is used by the system in the meantime.
Motivation:

We should not try to detect a free port in tests put just use 0 when bind so there is no race in which the system my bind something to the port we choosen before.

Modifications:

- Remove the usage of TestUtils.getFreePort() in the testsuite
- Remove hack to workaround bind errors which will not happen anymore now

Result:

Less flacky tests.

e5a31a4282 Automatically detect shaded packagePrefix
Motivation:

Shading requires renaming binary components (.so, .dll; for tcnative,
epoll, etc). But the rename then requires setting the
io.netty.packagePrefix system property on the command line or runtime,
which is either a burden or not feasible.

If you don't rename the binary components everything appears to
work, until a dependency on a second version of the binary component is
added. At that point, only one version of the binary will be loaded...
which is what shading is supposed to prevent. So for valid shading, the
binaries must be renamed.

Modifications:

Automatically detect the package prefix by comparing the actual class
name to the non-shaded expected class name. The expected class name must
be obfuscated to prevent shading utilities from changing it.

Result:

When shading and using binary components, runtime configuration is no
longer necessary.

Pre-existing shading users that were not renaming the binary components
will break, because the packagePrefix previously defaulted to "". Since
these pre-existing users had broken configurations that only _appeared_
to work, this breakage is considered a Good Thing. Users may workaround
this breakage temporarily by setting -Dio.netty.packagePrefix= to
restore packagePrefix to "".

3d22b24244 Allowed Netty Epoll/Kqueue to work in IPv6 Only environments
Motivation:
In some environments, IPv4 may be disabled (at a kernel level).
Google has such an environment for testing v4 -> v6 transition
paths.  This give confidence that code is v6 ready.

Modifications:
Change native socket code to ignore failures of trying to enter
dual stack mode.  This change has been made to Google's internal
JDK, and will/should be upstreamed to OpenJDK eventually.

Results:
Netty works in IPv6 only environments

a91df58ca1 HTTP/2 enforce HTTP message flow
Motivation:
codec-http2 currently does not strictly enforce the HTTP/1.x semantics with respect to the number of headers defined in RFC 7540 Section 8.1 [1]. We currently don't validate the number of headers nor do we validate that the trailing headers should indicate EOS.

[1] https://tools.ietf.org/html/rfc7540#section-8.1

Modifications:
- DefaultHttp2ConnectionDecoder should only allow decoding of a single headers and a single trailers
- DefaultHttp2ConnectionEncoder should only allow encoding of a single headers and optionally a single trailers

Result:
Constraints of RFC 7540 restricting the number of headers/trailers is enforced.

4af47f0ced AbstractByteBuf.setCharSequence(...) must not expand buffer
Motivation:

AbstractByteBuf.setCharSequence(...) must not expand the buffer if not enough writable space is present in the buffer to be consistent with all the other set operations.

Modifications:

- Ensure we only exand the buffer on writeCharSequence(...) but not on setCharSequence(...)
- Add unit tests.

Result:

08748344d8 Fix NPEs in HttpPostRequestEncoder#nextChunk
Motivation:

HttpPostRequestEncoder maintains an internal buffer that holds the
current encoded data. There are use cases when this internal buffer
becomes null, the next chunk processing implementation should take
this into consideration.

Modifications:

- When preparing the last chunk if currentBuffer is null, mark
isLastChunkSent as true and send LastHttpContent.EMPTY_LAST_CONTENT
- When calculating the remaining size take into consideration that the
currentBuffer might be null
- Tests are based on those provided in the issue by @nebhale and @bfiorini

3e9f617504 Deduplicate and simplify code in HttpPostMultipartRequestDecoder
Motivation:

- A `HttpPostMultipartRequestDecoder` contains two pairs of the same methods: `readFileUploadByteMultipartStandard`+`readFileUploadByteMultipart` and `loadFieldMultipartStandard`+`loadFieldMultipart`.
- These methods use `NotEnoughDataDecoderException` to detecting not last data chunk (exception handling is very expensive).
- These methods can be greatly simplified.
- Methods `loadFieldMultipart` and `loadFieldMultipartStandard` has an unnecessary catching for the `IndexOutOfBoundsException`.

Modifications:

- Remove duplicate methods.
- Replace handling `NotEnoughDataDecoderException` by the return of a boolean result.
- Simplify code.

Result:

The code is cleaner and easier to support. Less exception handling logic.

6152990073 OpenSslEngine protocol selection must be contiguous
Motivation:
TLS doesn't support a way to advertise non-contiguous versions from the client's perspective, and the client just advertises the max supported version. The TLS protocol also doesn't support all different combinations of discrete protocols, and instead assumes contiguous ranges. OpenSSL has some unexpected behavior (e.g. handshake failures) if non-contiguous protocols are used even where there is a compatible set of protocols and ciphers. For these reasons this method will determine the minimum protocol and the maximum protocol and enabled a contiguous range from [min protocol, max protocol] in OpenSSL.

Modifications:
- ReferenceCountedOpenSslEngine#setEnabledProtocols should determine the min/max protocol versions and enable a contiguous range

Result:
OpenSslEngine is more consistent with the JDK's SslEngineImpl and no more unexpected handshake failures due to protocol selection quirks.

43ae9748d0 Unify default cipher suites betweek JDK and OpenSSL
Motivation:
Currently the default cipher suites are set independently between JDK and OpenSSL. We should use a common approach to setting the default ciphers. Also the OpenSsl default ciphers are expressed in terms of the OpenSSL cipher name conventions, which is not correct and may be exposed to the end user. OpenSSL should also use the RFC cipher names like the JDK defaults.

Modifications:
- Move the default cipher definition to a common location and use it in JDK and OpenSSL initialization
- OpenSSL should not expose OpenSSL cipher names externally

Result:
Common initialization and OpenSSL doesn't expose custom cipher names.

b249714a2d DNS Resovler tests should be more explicit about ndots
Motivation:
The DNS resolver may use default configuration inherited from the environment. This means the ndots value may change and result in test failure if the tests don't explicitly set the assumed value.

Modifications:
- Explicitly set ndots in resolver-dns unit tests so we don't fail if the environment overrides the search domain and ndots

Result:
Unit tests are less dependent upon the enviroment they run in.

e5455d31b3 Fix Race in ReferenceCountedOpenSslEngine
Motivation:
ReferenceCountedOpenSslEngine is careful to lock access to `ssl`
almost everywhere (manually verified) *except* in the constructor.
Since `ssl` is non-final, it does not enjoy automatic thread safety
of the code that uses it.  Specifically, that means netty tcnative
code is not thread safe.

Modifications:

Ensure that all ssl engine intialization and variables related to
it are properly synchronized  by adding in the constructor.

Result:
Less noisy race detector.

Notes:
The specific racing threads are:

81fb2eede8 Revert "Revert "SslHandler avoid calling wrap/unwrap when unnecessary""
Motivation:
PR https://github.com/netty/netty/pull/6803 corrected an error in the return status of the OpenSslEngine. We should now be able to restore the SslHandler optimization.

Modifications:
- This reverts commit 7f3b75a509.

Result:
SslHandler optimization is restored.

7cfe416182 Use unbounded queues from JCTools 2.0.2
Motivation:
JCTools 2.0.2 provides an unbounded MPSC linked queue. Before we shaded JCTools we had our own unbounded MPSC linked queue and used it in various places but gave this up because there was no public equivalent available in JCTools at the time.

Modifications:
- Use JCTool's MPSC linked queue when no upper bound is specified

Result:
Fixes https://github.com/netty/netty/issues/5951
