Motivation:
To be able to easily build only one of the native sub-modules its needed that all the dependencies can be fetched from maven. At the moment we dont deploy transport-native-unix-common and so an attempt to just build for example the native epoll transport fails with:
[ERROR] Failed to execute goal on project netty-transport-native-epoll: Could not resolve dependencies for project io.netty:netty-transport-native-epoll:jar:4.1.13.Final-SNAPSHOT: Could not find artifact io.netty:netty-transport-native-unix-common-tests:jar:4.1.13.Final-SNAPSHOT in sonatype-nexus-snapshots (https://oss.sonatype.org/content/repositories/snapshots) -> [Help 1]
Modifications:
Deploy jar
Result:
All dependencies on maven repository.
Motivation:
Commit 3c4dfed08a introduced a regression in handling buffers that have no memoryAddress.
Modifications:
Fix regression and also add unit tests.
Result:
It's possible again to write buffers without memory address.
Motivation:
1. special handling of ByteBuf with multi nioBuffer rather than type of CompositeByteBuf (eg. DuplicatedByteBuf with CompositeByteBuf)
2. EpollDatagramUnicastTest and KQueueDatagramUnicastTest passed because CompositeByteBuf is converted to DuplicatedByteBuf before write to channel
3. uninitalized struct msghdr will raise error
Modifications:
1. isBufferCopyNeededForWrite(like isSingleDirectBuffer in NioDatgramChannel) checks wether a new direct buffer is needed
2. special handling of ByteBuf with multi nioBuffer in EpollDatagramChannel, AbstractEpollStreamChannel, KQueueDatagramChannel, AbstractKQueueStreamChannel and IovArray
3. initalize struct msghdr
Result:
handle of ByteBuf with multi nioBuffer in EpollDatagramChannel and KQueueDatagramChannel are ok
Motivation:
MacOS will throw an error when attempting to set the IP_TOS socket option if IPv6 is available, and also when getting the value for IP_TOS.
Modifications:
- Socket#setTrafficClass and Socket#getTrafficClass should try to use IPv6 first, and check if the error code indicates the protocol is not supported before trying IPv4
Result:
Fixes https://github.com/netty/netty/issues/6741.
Motivation:
We currently don't have a native transport which supports kqueue https://www.freebsd.org/cgi/man.cgi?query=kqueue&sektion=2. This can be useful for BSD systems such as MacOS to take advantage of native features, and provide feature parity with the Linux native transport.
Modifications:
- Make a new transport-native-unix-common module with all the java classes and JNI code for generic unix items. This module will build a static library for each unix platform, and included in the dynamic libraries used for JNI (e.g. transport-native-epoll, and eventually kqueue).
- Make a new transport-native-unix-common-tests module where the tests for the transport-native-unix-common module will live. This is so each unix platform can inherit from these test and ensure they pass.
- Add a new transport-native-kqueue module which uses JNI to directly interact with kqueue
Result:
JNI support for kqueue.
