Motivation:
SLF4J 1.7.30 is the latest version in 1.7.x and we should upgrade to it from 1.7.21.
Modification:
Changed 1.7.21 to 1.7.30
Result:
Newer version of SLF4J
Motivation:
Since GraalVM version 19.3.0, instances of java.net.InetAddress (and its subclasses Inet4Address and Inet6Address) are not allowed in native image heap (that is, they cannot be stored in static fields of classes initialized at build time or be reachable through static fields of such classes). When building a native image, it makes sense to initialize at build time as many classes as possible.
But some fields of some classes in Netty (for example, NetUtil.LOCALHOST4) contain InetAddress instances. If a program is using code path that makes it possible to reach such fields at build time initialization, it becomes impossible to build a native image initializing core Netty classes initialized at runtime. An example of such a program is a client that uses netty-dns.
Modifications:
- Add netty-testsuite-native-image-client Maven module to test that such an example program can be built after the corresponding fixes
- Add native-image.properties to resolver-dns module to move initialization of some classes to runtime (some of them are parsing configuration during initialization, so it makes no sense to initialize them at build time; for others, it's needed to avoid InetAddress reachability at build time)
- Add substitutions for NetUtil.LOCALHOST4, NetUtil.LOCALHOST6 and NetUtil.LOCALHOST to overcome the InetAddress-related prohibition
- Extract some initialization code from NetUtil to NetUtilInitializations to allow it to be used by the substitutions
Result:
A client program using netty-dns with --initialize-at-build-time=io.netty builds successfully
Motivation:
HTTP is a plaintext protocol which means that someone may be able
to eavesdrop the data. To prevent this, HTTPS should be used whenever
possible. However, maintaining using https:// in all URLs may be
difficult. The nohttp tool can help here. The tool scans all the files
in a repository and reports where http:// is used.
Modifications:
- Added nohttp (via checkstyle) into the build process.
- Suppressed findings for the websites
that don't support HTTPS or that are not reachable
Result:
- Prevent using HTTP in the future.
- Encourage users to use HTTPS when they follow the links they found in
the code.
Motivation:
26f3cd89ef did introduce a profile for compiling on JDK15 but did miss to set the compiler settings correctly for the requirements of this branch
Modifications:
Correct compiler settings.
Result:
Be able to build with JDK15
Motivation:
Java 16 will come around eventually anyway, and this makes it easier for people to experiment with Early Access builds.
Modification:
- Added Maven profiles for JDK 16 to relevant pom files.
- Removed the `--add-exports java.base/sun.security.x509=ALL-UNNAMED` argument when running tests; we've not needed it since the Java11-as-baseline PR landed.
Result:
Netty now builds on JDK 16 pre-releases (provided they've not broken compatibility in some way).
Raise the Netty 5 minimum required Java version to Java 11.
Motivation:
Java 11 has been out for some time, and Netty 5 is still some ways out.
There are also many good features in Java 11 that we wish to use, such as VarHandles, var-keyword, and the module system.
There is no reason for Netty 5 to not require Java 11, since Netty 4.x will still be supported for the time being.
Modification:
Remove everything in the pom files related to Java versions older than Java 11.
Remove the animal-sniffer plug-in and rely on the `--release` compiler flag instead.
Remove docker files related to Java versions older than Java 11.
Remove the copied SCTP APIs -- we should test this commit independently on Windows.
Remove the OpenJdkSelfSignedCertGenerator.java file and just always use Bouncy Castle for generating self-signed certificates for testing.
Make netty-testsuite tests pass by including Bouncy Castle as a test dependency, so we're able to generate our self-signed certificate.
Result:
Java 11 is now the minimum required Java version.
Bumps ant from 1.9.7 to 1.9.15.

Motivation:
Avoid keeping unused dependencies around.
Modification:
Remove all references to javassist dependency, since it does not appear to be used by anything.
Result:
One less dependency to worry about.
Motivation:
To reduce latency and RTTs we should use TLS False Start when jdkCompatibilityMode is not required and its supported
Modifications:
Use SSL_MODE_ENABLE_FALSE_START when jdkCompatibilityMode is false
Result:
Less RTTs and so lower latency when TLS False Start is supported
Motivation:
AlgorithmId.sha256WithRSAEncryption_oid was removed in JDK15 and later so we should not depend on it as otherwise we will see compilation errors
Modifications:
Replace AlgorithmId.sha256WithRSAEncryption_oid usage with specify the OID directly
Result:
Compiles on JDK15+
Motivation:
JCTools 3.1.0 is out and includes several fixes, see https://github.com/JCTools/JCTools/releases/tag/v3.1.0
Modification:
Upgrade jctools-core version in pom.xml
Result:
Netty ships latest version of jctools.
Motivation:
There was a new netty-tcnative release which we should use. Beside this the SSLErrorTest was quite fragile and so should be adjusted.
Modifications:
Update netty-tcnative and adjust test
Result:
Use latest netty-tcnative release
Motivation:
We are far behind with the version of Conscrypt we are using during testing. We should ensure we use the latest.
Modifications:
- Update conscrypt dependency
- Ensure we use conscrypt provider in tests
- Add workarounds for conscrypt bugs in testsuite
Result:
Use latest Conscrypt release
Motivation:
We need to make some slightly changes to be able to build on Java15 as some previous deprecated methods now throw UnsupportedOperationException
Modifications:
- Add code to handle UnsupportedOperationException
- Revert previous applied workaround for bug that was fixed in Java15
- Add maven profile
Result:
Be able to build with latest Java15 EA release
Motivation:
ALPN support was backported to java 8 lately. Ensure we support it if the user uses the latest java 8 release
Modifications:
- Update logic to be able to detect if ALPN is supported out of the box when using Java8
- Update jetty alpn version
Result:
Be able to use ALPN out of the box when using java 8u251
Motivation:
We should update our optional bouncycastle dependency to ensure we use the latest which has all the security fixes
Modifications:
Update bouncycastle version
Result:
Fixes https://github.com/netty/netty/issues/10184
Motivation:
JDK 14 was released and need some special settings to be able to build with. Also there seems to be one regression that we need to workaround for now.
Modifications:
- Add maven profile for JDK 14
- Update blockhound version to be able to work on JDK 14
- Add workaround for possible JDK 14 regression
Result:
Be able to build on JDK 14
Motivation:
As we have java8 as a minimum target we can use MethodHandles. We should do so when we expect to have a method called multiple times.
Modifications:
- Replace usage of reflection with MethodHandles where it makes sense
- Remove some code which was there to support java < 8
Result:
Faster code
Motivation:
Sometimes it is useful to do something depending on the Ssl ClientHello (like for example select a SslContext to use). At the moment we only allow to hook into the SNI extension but this is not enough.
Modifications:
Add SslClientHelloHandler which allows to hook into ClientHello messages. This class is now also the super class of AbstractSniHandler
Result:
More flexible processing of SSL handshakes
Motivation:
A new checkstyle version was released which fixes a security vulnerability.
Modifications:
- Update to latest checkstyle version
- Update netty-build to latest version to be compatible with latest checkstyle version
Result:
No more security vulnerability caused by checkstyle during build
Motivation:
Use latest JCTools, bug fixes etc.
Modification:
Change pom to depend on 3.0.0 version, and ignore shaded jar API changes
Result:
Using newer JCTools
Motivation:
"io.netty.leakDetection.maxSampledRecords" was removed in 16b1dbdf92
Modification:
Replaced it with targetRecords
Result:
Use correct flag during test execution
Motivation:
We should include the shaded sources for JCTools in our sources jar to make it easier to debug.
Modifications:
- Adjust plugin configuration to execute plugins in correct order
- Update source plugin
- Add configuration for shade plugin to generate source jar content
Result:
Fixes https://github.com/netty/netty/issues/6640.
Motivation:
21720e4a78 introduced a change which aimed to enable the not_x86_64 profile when building on a x86_64 platform. Unfortunaly it made an assemption which not holds true and so the profile was already enabled. This lead to the situation that native SSL tests were skipped if non boringssl impl was used.
Modifications:
Fix profile activation to work as expected
Result:
Correctly run aal native SSL tests
Motivation:
Netty currently doesn't build and distribute the test JARs. Having easy access to the test JARs would enable downstream projects (such as GraalVM) to integrate the Netty unit tests in their CI pipeline to ensure continous compatibility with Netty features. The alternative would be to build Netty from source every time to obtain the test jars, however, depending on the CI setup, that may not always be possible.
Modifications:
Modify `pom.xml` to enable generation of test JARs and corresponding source JARs.
Result:
Running the Maven build will create the test JARs and corresponding source JARs. This change was tested locally via `mvn install` and the test JARs are correctly copied under the Maven cache. The expectation is that running `mvn deploy` will also copy the additional JARs to the maven repository.
Motivation:
On MacOS it is not really good enough to check /etc/resolv.conf to determine the nameservers to use. We should retrieve the nameservers using the same way as mDNSResponser and chromium does by doing a JNI call.
Modifications:
Add MacOSDnsServerAddressStreamProvider and testcase
Result:
Use correct nameservers by default on MacOS.
Motivation:
Netty is an asynchronous framework.
If somebody uses a blocking call inside Netty's event loops,
it may lead to a severe performance degradation.
BlockHound is a tool that helps detecting such calls.
Modifications:
This change adds a BlockHound's SPI integration that marks
threads created by Netty (`FastThreadLocalThread`s) as non-blocking.
It also marks some of Netty's internal methods as whitelisted
as they are required to run the event loops.
Result:
When BlockHound is installed, any blocking call inside event loops
is intercepted and reported (by default an error will be thrown).
Motivation:
We should use the latest commons-compress release to fix CVE-2019-12402 (even it is only a test dependency)
Modifications:
Update commons-compress to 1.19
Result:
Fix security alert
Motivation:
It is not possible to build Netty on an s390_64 platform.
Modifications:
Modify pom.xml so that s390_64 is acceptable as os.detected.arch.
Result:
Netty can be built on an s390_64 platform.

Motivation:
We just released a new version of netty-tcnative.
Modifications:
Bump up to netty-tcnative 2.0.26.Final
Result:
Use latest netty-tcnative release
Motivation:
At the moment it is not possible to build netty on a power 8 systems.
Modifications:
- Improve detection of the possibility of using Conscrypt
- Skip testsuite-shading when not on x86_64 as this is the only platform for which we build tcnative atm
- Only include classifier if on x86_64 for tcnative as dependency as this is the only platform for which we build tcnative atm
- Better detect if UDT test can be run
Result:
Fixes https://github.com/netty/netty/issues/9479
Motivation:
Users' runtime systems may have incompatible dynamic libraries to the ones our
tcnative wrappers link to. Unfortunately, we cannot determine and catch these
scenarios (in which the JVM crashes) but we can make a more educated guess on
what library to load and try to find one that works better before crashing.
Modifications:
1) Build dynamically linked openSSL builds for more OSs (netty-tcnative)
2) Load native linux libraries with matching classifier (first)
Result:
More developers / users can use the dynamically-linked native libraries.
Motivation:
Since both projects (to some extend) rely on classifier parsing via the
os-maven-plugin, they should ideally use the same version in case the parsing
changed.
Modifications:
Upgrade os-maven-plugin from 1.6.0 to 1.6.2
Result:
Same os-maven-plugin with same parsing logic.
Motivation:
Netty homepage(netty.io) serves both "http" and "https".
It's recommended to use https than http.
Modification:
I changed from "http://netty.io" to "https://netty.io"
Result:
No effects.
Motivation:
The first final version of GraalVM was released which deprecated some flags. We should use the new ones.
Modifications:
Removes the use of deprecated GraalVM native-image flags
Adds a flag to initialize netty at build time.
Result:
Do not use deprecated flags
Motivation:
We did not release any version of netty 5 yet so we need to skip the usage of the Japicmp plugin.
Modifications:
Skip plugin execution
Result:
Build works
Motivation:
When trying to use graalvm and build netty we currently fail because our build configuration is not compatible with it.
Modification:
- Skip plugins that are not supported when graal is used
- Correctly configure surefire plugin for graal so it not produces a NPE
Result:
We can build and test with graalvm.
Motivation:
GraalVM native images are a new way to deliver java applications. Netty is one of the most popular libraries however there are a few limitations that make it impossible to use with native images out of the box. Adding a few metadata (in specific modules will allow the compilation to success and produce working binaries)
Modification:
Added properties files in `META-INF` and substitutions classes (under `internal.svm`) will solve the compilation issues. The substitutions classes are not visible and do not have a public constructor so they are not visible to end users.
Result:
Fixes#8959
This fix is very conservative as it applies the minimum config required to build:
* pure netty servers
* vert.x applications
* grpc applications
The build is having trouble due to checkstyle which does not seem to be able to find the copyright notice on property files.
Motivation:
We should update to netty-tcnative 2.0.25.Final as it fixes a possible segfault on systems that use openssl < 1.0.2 and for which we compiled with gcc.
See https://github.com/netty/netty-tcnative/pull/457
Modifications:
Update netty-tcnative
Result:
No more segfault possible.
Motivation:
4079189f6b changed the dependency to netty-tcnative-borinssl-static but it should still be netty-tcnative.
Modifications:
Change back to netty-tcnative
Result:
Correct dependency is used
Motivation:
BoringSSL allows to customize the way how key signing is done an even offload it from the IO thread. We should provide a way to plugin an own implementation when BoringSSL is used.
Modifications:
- Introduce OpenSslPrivateKeyMethod that can be used by the user to implement custom signing by using ReferenceCountedOpenSslContext.setPrivateKeyMethod(...)
- Introduce static methods to OpenSslKeyManagerFactory which allows to create a KeyManagerFactory which supports to do keyless operations by let the use handle everything in OpenSslPrivateKeyMethod.
- Add testcase which verifies that everything works as expected
Result:
A user is able to customize the way how keys are signed.
Motivation:
com.puppycrawl.tools checkstyle < 8.18 was reported to contain a possible security flaw. We should upgrade.
Modifications:
- Upgrade netty-build and checkstyle.
- Fix checkstyle errors
Result:
Fixes https://github.com/netty/netty/issues/8968.
Motivation:
We had a bug which could case ExtendedSSLSession.getPeerSupportedSignatureAlgorithms() return an empty array when using BoringSSL. This testcase verifies we correctly return algorithms after the fix in https://github.com/netty/netty-tcnative/pull/449.
Modifications:
Add testcase to verify behaviour.
Result:
Ensure we correctly retuen the algorithms.
