605290f821 Don't create a new ParserImpl on each parser() call (#11255)
Motivation:

ParserImpl is stateless and so we can use the same instance multiple times

Modifications:

- Make constructor private
- Return the same instance all the time

Result:

Less object creation

7f04b28bc7 Add DefaultHostsFileEntriesResolver#addresses to provide all hosts file's entries for a hostname (#11246)
Motivation:
DefaultHostsFileEntriesResolver should provide all hosts file's entries for a hostname when
DnsNameResolver#resolveAll as opposed to the current implementation where only the first
entry is taken into consideration

Modification:
- Add DefaultHostsFileEntriesResolver#addresses to provide all hosts file's entries for a hostname
- Add HostsFileEntriesProvider to provide all hosts file's entries for a hostname and to keep
backwards compatibility for HostsFileEntries and HostsFileParser
- DnsNameResolver#resolveAll uses the new DefaultHostsFileEntriesResolver#addresses
- BlockHound configuration: replace HostsFileParser#parse with HostsFileEntriesProvider$ParserImpl#parse
as the latter does the parsing
- Add junit tests

Result:
Fixes #10834

0d93c24547 Change asterisk to 'x' in FQDN of SelfSignedCertificate (#11245)
Motivation:

`SelfSignedCertificate` creates a certificate and private key files and store them in a temporary directory. However, if the certificate uses a wildcard hostname that uses asterisk *, e.g. `*.shieldblaze.com`, it'll throw an error because * is not a valid character in the file system.

Modification:
Replace the asterisk with 'x'

Result:
Fixes #11240

Motivation:

Just use MAVEN_OPTS to setup all the timeouts etc for dependency downloads. This way we at least can be sure these are applied.

Modifications:

- Use MAVEN_OPTS
- Remove ci profile
- Remove unused settings.xml file
- Always use ./mvnw

Result:

1602b96a25 Use tasks by default when using openssl based SSL provider (#11242)
Motivation:

We introduced the ability to offload certain operations to an executor that may take some time to complete. At the moment this is not enabled by default when using the openssl based SSL provider. Let's enable it by default as we have this support for some while now and didnt see any issues yet. This will also make things less confusing and more consistent with the JDK based provider.

Modifications:

Use true as default value for io.netty.handler.ssl.openssl.useTasks.

Result:

Offloading works with openssl based SSL provider as well by default

- Disable TLSv1 and TLSv1.1 by default when using OpenSSL.
- Add unit tests

Result:

b9685a63de Use PlatformDependent#normalizedOs() instead of reading os.name prop (#11239)
Motivation:

`PlatformDependent#normalizedOs()` already caches normalized variant of
the value of `os.name` system property. Instead of inconsistently
normalizing it in every case, use the utility method.

Modifications:

- `PlatformDependent`: `isWindows0()` and `isOsx0()` use `NORMALIZED_OS`;
- `PlatformDependent#normalizeOs(String)` define `darwin` as `osx`;
- `OpenSsl#loadTcNative()` does not require `equalsIgnoreCase` bcz `os`
is already normalized;
- Epoll and KQueue: `Native#loadNativeLibrary()` use `normalizedOs()`;
- Use consistent `Locale.US` for lower case conversion of `os.name`;
- `MacOSDnsServerAddressStreamProvider#loadNativeLibrary()` uses
`PlatformDependent.isOsx()`;

Result:

Consistent approach for `os.name` parsing.

57b0d6fe26 Re-order list of resolvers according to their searchOrder (#11236)
Motivation:
Mac OS specific DNS resolver fails to take into account search order
of resolvers causing wrong resolver being used is some circumstances

Modifications:
Re-order array of resolvers using their sort order as an ordering key.
Final order is opposite of the search order to make sure that resolver
with the lower sort order goes last (so it overrides previous one
in the `resolverMap`).

Result:
Fixes issue https://github.com/netty/netty/issues/11225

92ff402f0f Introduce BrotliDecoder (#10960)
Motivation:

Netty lacks client side support for decompressing Brotli compressed response bodies.

Modification:

* Introduce optional dependency to brotli4j by @hyperxpro. It will be up to the user to provide the brotli4j libraries for the target platform in the classpath. brotli4j is currently available for Linux, OSX and Windows, all for x86 only.
* Introduce BrotliDecoder in codec module
* Plug it onto `HttpContentDecompressor` for HTTP/1 and `DelegatingDecompressorFrameListener` for HTTP/2
* Add test in `HttpContentDecoderTest`
* Add `BrotliDecoderTest` that doesn't extend `AbstractDecoderTest` that looks flaky

Result:

Netty now support decompressing Brotli compressed response bodies.

414de53226 Use profile for overriding properties when building on the CI (#11232)
Motivation:

0f25213918 introduced some properties that were used to make builds more stable on the ci. All of these properties were duplicated everywhere, this made it hard to maintain

Modifications:

- Add profile which sets the properties.
- Just use the profile when build on the ci

Result:

Easier to maintain custom properties for the ci build

7cbd84f467 Workaround frequent connection reset / timeout on CI (#11231)
Motivation:

It seems like it is a known issue that maven frequently sees connection reset / connection timeout during CI builds. We should workaround these issues like others did:

- https://github.com/kiegroup/kie-wb-common/pull/3416

Modifications:

Add extra maven options during build to reduce the likelyness of timeouts / resets

Result:

584d674acd Bump initial timeouts in SSLEngineTest (#11221)
Motivation:
We've seen (very rare) flaky test failures due to timeouts.
They are too rare to analyse properly, but a theory is that on overloaded, small cloud CI instances, it can sometimes take a surprising amount of time to start a thread.
It could be that the event loop thread is getting an unlucky schedule, and takes seconds to start, causing the timeouts to elapse.

Modification:
Increase the initial timeouts in the SSLEngineTest, that could end up waiting for the event loop thread to start.
Also fix a few simple warnings from Intellij.

Result:
Hopefully we will not see these tests be flaky again.

Only fall back to CNAME on A/AAAA queries (#11216)
Motivation:

DNS resolver falls back to trying CNAME if no records found, but should
only try this for A/AAAA queries. Does not make sense for other query
types, results in a redundant CNAME query that is just going to fail.

Modification:

Check query type before deciding to try CNAME. Only proceed if type is A
or AAAA.

Added unit test to verify CNAME is only tried after A/AAAA queries.

Result:

Fixes #11214.

d2643ed835 Decrease visibility of Http2FrameCodecBuilder default ctor to protected (#11220)
Motivation:

`Http2FrameCodecBuilder` defines static factory methods `forClient()`
and `forServer()` that should be used to create a new instance.
The default ctor is useful only when users need to override behavior
of the existing builder. Those users should define another way to create
an instance.

Modifications:

- Decrease visibility of `Http2FrameCodecBuilder` default ctor from
`public` to `protected`;
- Add javadoc to clarity responsibilities;

Result:

Users of `Http2FrameCodecBuilder` are not confused why
`new Http2FrameCodecBuilder().build()` works for the server-side, but
does not work for the client-side.

90213d3fb4 Don't bundle all netty dependencies into netty-all (#11202)
Motivation:

netty-all already depends on the other netty-* packages so there's no need to also bundle them.

The duplicated classes cause classpath issues, particularly with Java > 8, which reports errors like this:
The package io.netty.buffer is accessible from more than one module: io.netty.all, io.netty.buffer

Modifications:

- Removed bundling tasks from netty-all's maven pom.xml

Result:

- netty-all no longer bundles all classes. Instead, classes are provided by expressed dependencies.

968dfbb378 Preload classes before calling native OnLoad function to prevent clas… (#11215)
Motivation:

It turns out it is quite easy to cause a classloader deadlock in more recent java updates if you cause classloading while you are in native code. Because of this we should just workaround this issue by pre-load all the classes that needs to be accessed in the OnLoad function.

Modifications:

- Preload all classes that would otherwise be loaded by native OnLoad functions.

Result:

Workaround for https://github.com/netty/netty/issues/11209 and https://bugs.openjdk.java.net/browse/JDK-8266310

5309422669 Fix Memory release not correctly in Multipart Decoder (#11188)
Motivation:
2 years ago a change remove the default clearing of all HttpData, whatever
they are disk based or memory based.

A lot of users were probably releasing HttpData directly, so there was no issue.
But now, it seems, and as the Javadoc said, that `decoder.destroy()` shall clean up
also Memory based HttpData, and not only Disk based HttpData as currently.

Change:
- Add in `destroy()` method the necessary code to release if necessary
the underlying Memory based HttpDatas.

- Change one Junit Test (using Mixed, Memory and Disk based factories)
in order to check the correctness of this behavior and to really act
as a handler (releasing buffers or requests).

- Modify one Junit core to check validity when a delimiter is present in the Chunk
but not CRLF/LF (false delimiter), to ensure correctness.

Result:
No more issue on memory leak

Note that still the List and the Map are not cleaned, since they were not
before. No change is done on this, since it could produce backward issue compatibility.

672a325e93 Improve Http2FrameCodecBuilder usability (#11195)
__Motivation__

 `Http2FrameCodecBuilder` constructor calls `server()` internally which disallows using certain methods on the builder later. Additionally, the constructor is package private which limits extension of the `Builder` as well as usage outside the available `forClient()` and `forServer()` static methods.

 __Modification__

 - Introduce a `public` no-arg constructor to `Http2FrameCodecBuilder`.

 __Result__

 `Http2FrameCodecBuilder` can now be used to create the codec with `Http2Connection` or `Http2ConnectionDecoder` and `Http2ConnectionEncoder` which was earlier not possible due to implicit call to `server()` by the `Http2FrameCodecBuilder` constructor.

382885538f ReferenceCountedOpenSslEngine unwrap handshake complete status fix (#11210)
Motivation:
ReferenceCountedOpenSslEngine may unwrap data and complete the handshake
in a single unwrap() call. However it may return HanshakeStatus of
HandshakeStatus of NEED_UNWRAP instead of FINISHED. This may result in
the SslHandler sending the unwrapped data up the pipeline before
notifying that the handshake has completed, and result in out-of-order
events.

Modifications:
- if ReferenceCountedOpenSslEngine handshake status is NEED_UNWRAP and
  produced data, or NEED_WRAP and consumed some data, we should call
  handshake() to get the current state.

Result:
ReferenceCountedOpenSslEngine correctly indicates when the handshake has
finished if at the same time data was produced or consumed.

438632a3ac Give a choice for app to extend the length limitation of clientId even in mqtt v3.1 on the server side (#11205)
Motivation:

In the mqtt v3.1 protocol, the default maximum Client Identifier length is 23.However, in (#11114), there are many cases, the server may still receive a client ID with a length greater than 23. Perhaps should consider letting the user decide whether accept client id greater than 23 on the server side

Modification:

- Allow to specify max length.

Result:

Give a choice for app to extend the length limitation of clientId even in mqtt v3.1 on the server side.

- Add unit tests

They must be specific and should not be done with an "OR-Logic" (if a == null || b == null) throw new NullPointerEx.

Modifications:

* import static relevant checks
* Replace manual checks with ObjectUtil methods

Result:

All checks needed are done with ObjectUtil, some exception texts are improved.

Fixes #11170

8c12ad4cee SimpleChannelPromiseAggregator use first exception instead of last (#11168)
Motivation:
SimpleChannelPromiseAggregator implements the promise API and allows for
multiple operations to share a common promise. It currently propagates
the last exception to occur, but this may mask the original exception
which lead to the last exception and make debugging more difficult.

Modifications:
- SimpleChannelPromiseAggregator propagates the first exception instead
  of the last exception.

Result:
Fixes https://github.com/netty/netty/issues/11161.
