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:
This reverts commit 7fb62a93b8 as it broke native loading in some cases due maven dependencies.
Modification:
Revert the commit.
Result:
Native loading works again
Motivation:
We need to ensure we only register native methods once as otherwise we may end up in an "invalid" state. The problem here was that before it was basically the responsibility the user of transport-native-unix-common to register the methods. This is error prone as there may be multiple users of these on the classpath at the same time.
Modifications:
- Provide a way to init native lib without register the native methods of the provided classes. This is needed to be able to re-use functionality which is exposed to our internal native code
- Use flatten plugin to correctly resolve classifier and so have the correct dependency
- Call Unix.* method to ensure we register the methods correctly once
- Include native lib as well in the native jars of unix-common
Result:
Be able to have multiple artifacts of the classpath that depends on the unix-common. Related to https://github.com/netty/netty-incubator-transport-io_uring/issues/15
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
