Motivation:
As more and more people switch to a mac m1 we should support it
Modifications:
- Add profiles for cross-compile for mac m1
- Adjust script to finish release
Result:
Mac m1 is supported
Motivation:
ccca3959fd fixed a regression which caused the native resolver code to not be loaded but this was not reported by the tests.
Modifications:
Adjust tests to actually fail the build if we cant load the native lib
Result:
Ensure we don't introduce another regression in the future
Motivation:
Cannot load the native library for DNS resolutions on MacOS.
The exception below is observed:
18:02:43.453 [Test worker] ERROR i.n.r.d.DnsServerAddressStreamProviders - Unable to load io.netty.resolver.dns.macos.MacOSDnsServerAddressStreamProvider, fallback to system defaults. This may result in incorrect DNS resolutions on MacOS.

This is a regression made with #11239
Modification:
When checking for OS, an exception must be thrown when the OS is not MacOS
Result:
The native library for DNS resolutions on MacOS can be loaded
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.
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
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
netty-jni-util 0.0.2.Final is incompatible with static linking. Before
the netty-jni-util dependency was introduced netty-tcnative supported
static linking via NETTY_BUILD_STATIC. netty-jni-util 0.0.3.Final adds
static linking compatibility.
Modifications:
Bump netty-jni-util to version 0.0.3.Final and update to its new API
which requires the caller to manage packagePrefix.
Result:
Using latest version of netty-jni-util and restored static linking
compatibility.
Motivation:
We should add some more NULL checks to ensure we not SEGV in some cases
Modifications:
Add more NULL checks
Result:
More robust implementation
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:
a63faa4fa1 missed to update the macos specific c files for the resolver.
Modifications:
Fix up c files so it compiles again on macos
Result:
Compiles on macos again
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:
junit deprecated Assert.assertThat(...)
Modifications:
Use MatcherAssert.assertThat(...) as replacement for deprecated method
Result:
Less deprecation warnings
Motivation:
939e928312 introduced MacOSDnsServerAddressStreamProvider which will ensure the right nameservers are selected when running on MacOS. To ensure this is done automatically on MacOS we should use it by default on these platforms.
Modifications:
Try to use MacOSDnsServerAddressStreamProvider when on MacOS via reflection and fallback if not possible
Result:
Ensure the right nameservers are used on MacOS even when a VPN (for example) is used.
Motivation:
The resolver API and implementations should be considered stable by now so we should not mark these with @UnstableApi
Modifications:
Remove @UnstableApi annotation from API and implementation of resolver
Result:
Make it explicit that the API is considered stable
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.
