Motivation:
LSE (https://mysqlonarm.github.io/ARM-LSE-and-MySQL/) can have a huge performance difference. Let's ensure we use a compiler that can support it.
Modifications:
Update to gc10 when cross-compiling as it supports LSE and enables it by default
Result:
More optimized builds for aarch64
Motivation:
We should use aarch_64 in our classifier / jni libname on aarch64 as os.detected.arch uses the name. Being non consistent (especially across our different projects) already gave us a lot of trouble in the past.
Let's fix this once for all.
Modifications:
Use aarch_64
Result:
More consistent classifier usage on aarch64
Motivation:
https in xmlns URIs does not work and will let the maven release plugin fail:

Modifications:
Use http for xmlns
Result:
Be able to use maven release plugin
Motivation:
We had a lot of duplication in our jni code which was mostly due macros but also related to how we support shading. By using netty-jni-util we can share all the code between netty and netty-tcnative ( and possible other jni based netty projects in the future).
Modifications:
- Use netty-jni-util and re-use its macros / functions
- Remove duplicated code
- Adjust build files
Result:
Less code duplication for JNI
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:
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).
Motivation:
`transport-native-epoll` doesn't have ARM release package.
Modification:
This PR added cross compile profile for epoll. Then we can easily build aarch64 package on X86 machine.
Result:
Fixes#8279
Motivation:
394a1b3485 introduced a hard dependency on GLIBC 2.12 which was not the case before. This had the effect of not be able to use the native epoll transports on platforms which ship with earlier versions of GLIBC.
To make things a backward compatible as possible we should not introduce such changes in a bugfix release.
Special thanks to @weissi with all the help to fix this.
Modifications:
- Use syscalls directly to remove dependency on GLIBC 2.12
- Make code consistent that needs newer GLIBC versions
- Adjust scattering read test to only run if recvmmsg syscall is supported
- Cleanup pom.xml as some stuff is not needed anymore after using syscalls.
Result:
Fixes https://github.com/netty/netty/issues/9758.
Motivation:
The build script for the module Netty Transport Native Epoll can cause
intermittent build break due to broken pipe by /usr/bin/ldd. This issue
likely to occur on a build environment with multiple processors.
Modifications:
The root cause is that the consumer head command finishes earlier the
producer ldd command. Buffering the outputs of the ldd command by an
intermediate tail command avoids the broken pipe.
Result:
A build on multiple processors can finish successfully.

Motivation:
We should not only include the java source files but also the c source file in our source jars.
Modifications:
Add files from src/main/c as well
Result:
Fixes https://github.com/netty/netty/issues/9494
Motivation:
On openSUSE (probably more), 64 bit builds use lib64, e.g. /usr/lib64, and
configure picks this up and builds the native library in
native-build/target/lib64 where maven is not looking.
Modifications:
Explicitly specify --libdir=${project.build.directory}/native-build/target/lib
during configuration.
Result:
Maven uses the correct lib directory.
Motivation:
At some point we needed --add-opens=java.base/java.nio=ALL-UNNAMED to run our native tests but this is not true anymore.
Modifications:
Remove --add-opens=java.base/java.nio=ALL-UNNAMED when running native tests.
Result:
Remove obsolate jvm arg.
Motivation:
We need to update to a new checkstyle plugin to allow the usage of lambdas.
Modifications:
- Update to new plugin version.
- Fix checkstyle problems.
Result:
Be able to use checkstyle plugin which supports new Java syntax.
Motivation:
Most of the maven modules do not explicitly declare their
dependencies and rely on transitivity, which is not always correct.
Modifications:
For all maven modules, add all of their dependencies to pom.xml
Result:
All of the (essentially non-transitive) depepdencies of the modules are explicitly declared in pom.xml
Motivation:
We should support to load multiple shaded versions of the same netty artifact as netty is often used in multiple dependencies.
This is related to https://github.com/netty/netty/issues/7272.
Modifications:
- Use -fvisibility=hidden when compiling and use JNIEXPORT for things we really want to have exported
- Ensure fields are declared as static so these are not exported
- Adjust testsuite-shading to use install_name_tool on MacOS to change the id of the lib. Otherwise the wrong may be used.
Result:
Be able to use multiple shaded versions of the same netty artifact.
Automatic-Module-Name entry provides a stable JDK9 module name, when Netty is used in a modular JDK9 applications. More info: http://blog.joda.org/2017/05/java-se-9-jpms-automatic-modules.html
When Netty migrates to JDK9 in the future, the entry can be replaced by actual module-info descriptor.
Modification:
The POM-s are configured to put the correct module names to the manifest.
Result:
Fixes#7218.
