Motivation:
netty-jni-util is now also hosted on maven central. Let's use it
Modifications:
Adjust plugins to just unpack netty-jni-util and use it
Result:
Be able to use what is in the maven cache for netty-jni-util
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:
`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:
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:
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.
Motivation:
We rely upon the linker being non-lazy to test compatibility the native library compatibility for kqueue, but the default mode of operation is to lazy link.
Modifications:
- We should modify the build scripts to inform the linker that this library should not be lazy linked
- Error messages changes
dyld: lazy symbol binding failed: Symbol not found: _clock_gettime
java.lang.UnsatisfiedLinkError: unsupported JNI version 0xFFFFFFFF required by .../libnetty-transport-native-kqueue.dylib
Result:
Link errors are detected upon library load time.
