6fbb12e2c2 #7695 no need to manually release chunk during upload (#7696)
Motivation:

After #7527 fix there is no need to manually release chunks (HttpData) during file upload as they will be released on HttpPostRequestDecoder.destroy().

Modification:

HttpUploadServer example doesn't release chunks manually (doesn't call data.release()).

Result:
Fixes #7695 and #7689

Make it clear that HashedWheelTimer only support millis. (#8322)
Motivation:

HWT does not support anything smaller then 1ms so we should make it clear that this is the case.

Modifications:

Log a warning if < 1ms is used.

Result:

Less suprising behaviour.

9c70dc8ba5 Replaced obsolete cryptographic primitive with a modern/secure one. (#8450)
Motivation:

SHA1 is a broken hash function and shouldn't be used anymore (see: https://shattered.io/).
Security scanning tools will raise this as an issue and it will reflect badly on netty and I, therefore, recommend to use a SHA2 hash function which is secure and won't be flagged by such tools.

Modifications:

Replaced insecure SHA1 based signing scheme with SHA2.

Result:

Modern and thus secure cryptographic primitives will be in use and won't be flagged by security scanning tools.

PlatformDependent.maxDirectMemory() must respect io.netty.maxDirectMemory (#8452)
Motivation:

In netty we use our own max direct memory limit that can be adjusted by io.netty.maxDirectMemory but we do not take this in acount when maxDirectMemory() is used. That will lead to non optimal configuration of PooledByteBufAllocator in some cases.

This came up on stackoverflow:
https://stackoverflow.com/questions/53097133/why-is-default-num-direct-arena-derived-from-platformdependent-maxdirectmemory

Modifications:

Correctly respect io.netty.maxDirectMemory and so configure PooledByteBufAllocator correctly by default.

Result:

Correct value for max direct memory.

Add testcase for epollWait(...) with negative timerfd values. (#8447)
Motivation:

https://github.com/netty/netty/issues/8444 reports that there is some issue with negative values passed to timerfd_settime. This test verifies that everything is working as expected.

Modifications:

Add testcase.

Result:

Test to verify expected behaviour.

44cca1a26f Avoid allocations when wrapping byte[] and ByteBuffer arrays as ByteBuf (#8420)
Motivation:

Unpooled.wrap(byte[]...) and Unpooled.wrap(ByteBuffer...) currently
allocate/copy an intermediate ByteBuf ArrayList and array, which can be
avoided.

Modifications:

- Define new internal ByteWrapper interface and add a CompositeByteBuf
constructor which takes a ByteWrapper with an array of the type that it
wraps, and modify the appropriate Unpooled.wrap(...) methods to take
advantage of it
- Tidy up other constructors in CompositeByteBuf to remove duplication
and misleading len arg (which is really an end offset into provided
array)

Result:

Less allocation/copying when wrapping byte[] and ByteBuffer arrays,
tidier code.

Add test to verify that invalid ciphers are handled in all SSLEngine implementations correctly. (#8443)
Motivation:

https://github.com/netty/netty/issues/8442 reported that we fail to build a SslContext when an invalid cipher is used with netty-tcnative-boringssl-static, while it worked before. This test verifies that this is now consistent with all other SSLEngine implementations.

Modifications:

Add test-case to verify consistent behaviour

Result:

More tests to assert consistent behaviour across SSLEngine implementations

f4cf674f01 Fix NPE when trying to build a DnsNameResolver with a null resolvedAddressTypes (#8445)
Motivation:

It should be possible to build a DnsNameResolver with a null resolvedAddressTypes, defaulting then to DEFAULT_RESOLVE_ADDRESS_TYPES (see line 309).

Sadly, `preferredAddressType` is then called on line 377 with the original parameter instead of the instance attribute, causing an NPE when it's null.

Modification:

Call preferredAddressType with instance attribuet instead of constructor parameter.

Result:

No more NPE

44c3b824ec Remove uninterpolated {} in DefaultHttp2ConnectionDecoder log message (#8441)
Motivation:

There are log messages emitted from Http2ConnectionDecoder of the form
```
INF i.n.h.c.h.DefaultHttp2ConnectionDecoder ignoring HEADERS frame for stream RST_STREAM sent. {}
```

Modifications:

Remove the trailing `{}` in the log message that doesn't have a value.

Result:

Log messages no longer have a trailing `{}`.

Correctly init X509Certificate array when testing if we need to wrap the KeyManager due of TLSv1.3 (#8435)
Motivation:

201e984cb3 added support to use native TLSv1.3 support even with Java versions prior to 11. For this we try to detect if we need to wrap the used KeyManager or not. This testing code did create an X509Certificate[1] but does not correctly also set the certficiate on index 0. While this should be harmless we should better do the right thing and set it.

Modifications:

Correctly init the array.

Result:

Cleaner and more correct code.

48c45cf4ac Fix leak and corruption bugs in CompositeByteBuf (#8438)
Motivation:

I came across two bugs:
- Components removed due to capacity reduction aren't released
- Offsets aren't set correctly on empty components that are added
between existing components

Modifications:

Add unit tests which expose these bugs, fix them.

Result:

Bugs are fixed

Add profile to easily run testsuite against netty-tcnative-boringssl-static (#8436)
Motivation:

We should provide an easy way to run our testsuite against netty-tcnative-boringssl-static

Modifications:

- Add boringssl profile which can be used to enable usage of netty-tcnative-boringssl-static
- Make use of the profile in docker-compose

Result:

Cleaner and easier way of running testsuite against netty-tcnative-boringssl-static

d7fa7be67f Exploit PlatformDependent.allocateUninitializedArray() in more places (#8393)
Motivation:

There are currently many more places where this could be used which were
possibly not considered when the method was added.

If https://github.com/netty/netty/pull/8388 is included in its current
form, a number of these places could additionally make use of the same
BYTE_ARRAYS threadlocal.

There's also a couple of adjacent places where an optimistically-pooled
heap buffer is used for temp byte storage which could use the
threadlocal too in preference to allocating a temp heap bytebuf wrapper.
For example
https://github.com/netty/netty/blob/4.1/buffer/src/main/java/io/netty/buffer/ByteBufUtil.java#L1417.

Modifications:

Replace new byte[] with PlatformDependent.allocateUninitializedArray()
where appropriate; make use of ByteBufUtil.getBytes() in some places
which currently perform the equivalent logic, including avoiding copy of
backing array if possible (although would be rare).

Result:

Further potential speed-up with java9+ and appropriate compile flags.
Many of these places could be on latency-sensitive code paths.

583d838f7c Optimize AbstractByteBuf.getCharSequence() in US_ASCII case (#8392)
* Optimize AbstractByteBuf.getCharSequence() in US_ASCII case

Motivation:

Inspired by https://github.com/netty/netty/pull/8388, I noticed this
simple optimization to avoid char[] allocation (also suggested in a TODO
here).

Modifications:

Return an AsciiString from AbstractByteBuf.getCharSequence() if
requested charset is US_ASCII or ISO_8859_1 (latter thanks to
@Scottmitch's suggestion). Also tweak unit tests not to require Strings
and include a new benchmark to demonstrate the speedup.

Result:

Speed-up of AbstractByteBuf.getCharSequence() in ascii and iso 8859/1

Add support for boringssl and TLSv1.3 (#8412)
Motivation:

0ddc62cec0 added support for TLSv1.3 when using openssl 1.1.1. Now that BoringSSL chromium-stable branch supports it as well we can also support it with netty-tcnative-boringssl-static.
During this some unit tests failed with BoringSSL which was caused by not correctly handling flush() while the handshake is still in progress.

Modification:

- Upgrade netty-tcnative version which also supports TLSv1.3 when using BoringSSL
- Correctly handle flush() when done while the handshake is still in progress in all cases.

Result:

Easier for people to enable TLSv1.3 when using native SSL impl.
Ensure flush() while handshake is in progress will always be honored.

1cc692dd7d Fix incorrect reachability assumption in ResourceLeakDetector (#8410)
Motivation:

trackedObject != null gives no guarantee that trackedObject remains reachable. This may cause problems related to premature finalization: false leak detector warnings.
 
Modifications:

Add private method reachabilityFence0 that works on JDK 8 and can be factored out into PlatformDependent. Later, it can be swapped for the real Reference.reachabilityFence.
 
Result:

No false leak detector warnings in future versions of JDK.

Correctly detect if KeyManagerFactory is supported by OpenSSL even when sun.security.x509.* can not be accessed and bouncycastle is not on the classpath. (#8415)
Motivation:

OpenSsl used SelfSignedCertificate in its static init block to detect if KeyManagerFactory is supported. Unfortunally this only works when either sun.security.x509.* can be accessed or bouncycastle is on the classpath.
We should not depend on either of it.

This came up in https://github.com/netty/netty-tcnative/issues/404#issuecomment-431551890.

Modifications:

Just directly use the bytes to generate the X509Certificate and so not depend on sun.security.x509.* / bouncycastle.

Result:

Correctly be able to detect if KeyManagerFactory can be supported in all cases.

Remove workaround in tests for TLSv1.3 bug in Java11 as it was fixed in 11.0.1 (#8409)
Motivation:

We had put some workaround in our tests due a bug in the Java11 implementation of TLSv1.3. This was now fixes as part of 11.0.1.

See https://bugs.openjdk.java.net/browse/JDK-8211067.

Modifications:

Remove workaround in SSL tests.

Result:

Run all tests with supported TLS version.

Reduce overhead by ByteBufUtil.decodeString(...) which is used by AbstractByteBuf.toString(...) and AbstractByteBuf.getCharSequence(...) (#8388)
Motivation:

Our current implementation that is used for toString(Charset) operations on AbstractByteBuf implementation is quite slow as it does a lot of uncessary memory copies. We should just use new String(...) as it has a lot of optimizations to handle these cases.

Modifications:

Rewrite ByteBufUtil.decodeString(...) to use new String(...)

Result:

Less overhead for toString(Charset) operations.

CompositeByteBuf.decompose(...) does not correctly slice content. (#8403)
Motivation:

CompositeByteBuf.decompose(...) did not correctly slice the content and so produced an incorrect representation of the data.

Modifications:

- Rewrote implementation to fix bug and also improved it to reduce GC
- Add unit tests.

Result:

3a4a0432d3 Fix broken testsuite-shading when using with netty-tcnative-boringssl-static (#8404)
Motivation:

2109f14c24 corrected how we run the testsuite with boringssl-static but missed to also adjust the testsuite-shading configuration which lead to test failures.

Modifications:

Correctly compose the native lib name when no classifier is used.

Result:

Testsuite passes again.

a6f807dd68 Fix context and window sizes sides. (#8395)
Motivation:

As mentioned in RFC 7692 :

The "server_no_context_takeover" Extension Parameter should be used on server side for compression and on client side for decompression.

The "client_no_context_takeover" Extension Parameter should be used on client side for compression and on server side for decompression.

Right now, in PerMessageDeflateClientExtensionHandshaker, the decoder uses clientNoContext instead of serverNoContext and the encoder uses serverNoContext instead of clientNoContext.

The same inversion is present in PerMessageDeflateServerExtensionHandshaker: the decoder uses
serverNoContext instead of clientNoContext, while the encoder uses serverNoContext instead of clientNoContext. Besides the context inversion, the sliding window sizes seem to be inversed as well.

Modification:

Inverse clientNoContext with serverNoContext and clientWindowSize with serverWindowSize for both the Decoder and Encoder in PerMessageDeflateServerExtensionHandshaker and PerMessageDeflateClientExtensionHandshaker.

Result:

This fixes the decompression fail in the case that one of the contexts is set and the other one is not.

Allow to use TLSv1.3 with netty-tcnative withe java versions prior to 11. (#8394)
Motivation:

At the moment it's only possible to use TLSv1.3 with netty-tcnative if Java 11 is used. It should be possible to do so even with Java 8, 9 and 10.

Modification:

Add a workaround to be able to use TLSv1.3 also when using Java version prior to Java 11 and the default X509ExtendedTrustManager is used.

Result:

Be able to use TLSv1.3 also with past versions of Java.

Explicit specify java version to use to ensure we rebuild image when java version changes. (#8397)
Motivation:

We should explicit specify the java version to use to ensure docker will rebuild the image once a new java version was released and we specify it. Also we should use openjdk for testing when possible.

Modifications:

- Explicit specify the java versions to use
- Use openjdk when possible.

Result:

Ensure latest java versions are used during testing

Ensure OpenSslEngine will not try to call SSL_free multiple times even when constructor throws. (#8399)
Motivation:

When the constructor of OpenSslEngine threw we could end up to self call SSL_free by ourself and then have the finalizer do the same which may lead to double free-ing and so SIGSEV.

Modifications:

Just call shutdown() when the constructor throws and so ensure SSL_free is guarded correctly in the finalizer.

Result:

No more SIGSEV possible.

When running our testsuite with netty-tcnative-boringssl-static we should use an empty classifier. (#8396)
Motivation:

We publish an "uber-jar" for netty-tcnative-boringssl-static so we should use it when testing against boringssl.

Modifications:

Ensure we use empty classifier.

Result:

Use uber-jar when testing

Add support for TLSv1.3 (#8293)
Motivation:

TLSv1.3 support is included in java11 and is also supported by OpenSSL 1.1.1, so we should support when possible.

Modifications:
- Add support for TLSv1.3 using either the JDK implementation or the native implementation provided by netty-tcnative when compiled against openssl 1.1.1
- Adjust unit tests for semantics provided by TLSv1.3
- Correctly handle custom Provider implementations that not support TLSv1.3

Result:

Be able to use TLSv1.3 with netty.

9eebe7ed74 Add full JdkSslContext public constructor, close #8384 (#8389)
Motivation:

JdkSslContext provides public constructors to wrap an existing `javax.net.ssl.SSLContext`.

Sadly, some options combinations are not possible with the existing constructors, eg:
*  protocols is not exposed and always forced to null, so default protocols are always enforced
* startTls is not exposed and always forced to false

Modification:

Add full constructor that take protocols and startTls parameters.

Result:

It's possible to create a JdkSslContext from an existing SSLContext and still have control over protocols and startTls

Modifications:
- Bump h2spec-maven-plugin to 0.6
- Remove excluded specs that are no passing
- Add failing spec "half closed (remote): Sends a HEADERS frame" to
exclude list

Result:
Build will fail when non excluded specs fails.

b59336142f deprecate own ConcurrentSet for removal (#8340)
Motivation:

Java since version 6 has the wrapper for the ConcurrentHashMap that could be created via Collections.newSetFromMap(map). So no need to create own ConcurrentSet class. Also, since netty plans to switch to Java 8 soon there is another method for that - ConcurrentHashMap.newKeySet().
For now, marking this class @deprecated would be enough, just to warn users who use netty's ConcurrentSet. After switching to Java 8 ConcurrentSet should be removed and replaced with ConcurrentHashMap.newKeySet().

Modification:

ConcurrentSet deprecated.

7062ceedb0 Simplify ByteBufInputStream.readLine() logic (#8380)
Motivation:

While looking at the nice optimization done in
https://github.com/netty/netty/pull/8347 I couldn't help noticing the
logic could be simplified further. Apologies if this is just my OCD and
inappropriate!

Modifications:

Reduce amount of code used for ByteBufInputStream.readLine()

Result:

Slightly smaller and simpler code

Use MACOSX_DEPLOYMENT_TARGET=10.6 when compile native transport on MacOS (#8379)
Motivation:

MACOSX_DEPLOYMENT_TARGET=10.6 needs to be used as everything before is not supported in 10.14 anymore. 10.6 was released 2009 so this should be a safe thing to do.

Modifications:

Use MACOSX_DEPLOYMENT_TARGET=10.6

Result:

Be able to compile on MacOS 10.14

Prevent NPE when attempting to set client key material with no alias (#8378)
Motivation:

It is possible that a client is unable to locate a certificate alias given the list of issuers and key types. In this case the X509KeyManager
will return a null which when past to the OpenSslKeyMaterialProvider implementation may produce a NPE. If no matching alias could be found we should not
call OpenSslKeyMaterialProvider at all which is also consistent what OpenJDK does.

Modifications:

- Add null check before calling OpenSslKeyMaterialProvider
- Add unit test.

Result:

No more NPE caused by passing null as client alias.

5b3b8db07f epoll_wait produces an EINVAL error since 4.1.30 (#8350)
Motivation:

epoll_wait should work in 4.1.30 like it did in 4.1.29.

Modifications:

Revert Integer.MAX_VALUE back to MAX_SCHEDULED_TIMERFD_NS (999,999,999).
Add unit test.

Result:

epoll_wait will no longer throw EINVAL.

Correctly parse /etc/resolv.conf when contain multiple entries for searchdomain. (#8351)
Motivation:

ba594bcf4a added a utility to parse searchdomains defined in /etc/resolv.conf but did not correctly handle the case when multiple are defined that are seperated by either whitespace or tab.

Modifications:

- Correctly parse multiple entries
- Add unit test.

Result:

Correctly parse multiple searchdomain entries.

Correctly decrement pending bytes when submitting AbstractWriteTask fails. (#8349)
Motivation:

Currently we may end up in the situation that we incremented the pending bytes before submitting the AbstractWriteTask but never decrement these again if the submitting of the task fails. This may result in incorrect watermark handling.

Modifications:

- Correctly decrement pending bytes if subimitting of task fails and also ensure we recycle it correctly.
- Add unit test.

Result:

Fixes https://github.com/netty/netty/issues/8343.

0e4186c552 deprecate IntegerHolder for removal (#8339)
Motivation:

Seems like IntegerHolder counterHashCode field is the very old legacy field that is no longer used. Should be marked as deprecated and removed in the future versions.

Modification:

IntegerHolder class, InternalThreadLocalMap.counterHashCode() and InternalThreadLocalMap.setCounterHashCode(IntegerHolder counterHashCode) are now deprecated.

83dc3b503e ByteBufInputStream is always allocating a StringBuilder instance (#8347)
Motivation:

Avoid creating any StringBuilder instance if
ByteBufInputStream::readLine isn't used

Modifications:

The StringBuilder instance is lazy allocated on demand and
are added new test case branches to address the increased
complexity of ByteBufInputStream::readLine

Result:

Reduced GC activity if ByteBufInputStream::readLine isn't used

fc28bccdf1 Fix SelectableChannel support in NioEventLoop (#8344)
Motivation:

Unless the 'io.netty.noKeySetOptimization' system property is set,
registering a SelectableChannel instance to a NioEventLoop results
in a ClassCastException:

    io.netty.channel.nio.SelectedSelectionKeySetSelector cannot be cast
        to java.nio.channels.spi.AbstractSelector

Modifications:

Instead of 'selector', pass 'unwrappedSelector' to SelectableChannel.

Result:

It is possible to register a SelectableChannel instance without
setting the 'io.netty.noKeySetOptimization' system property.
