Windows 10 support for junixsocket

Duplicate of this.

Hi,

I have started using Docker for Windows Beta and trying to build a Docker image on my Windows machine using gradle.
It used to be fine on Linux, but on Windows 10 I get the following exception:

Operating System not officially supported by junixsocket: Windows 10
java.lang.UnsatisfiedLinkError: Could not find library in classpath, tried: [libjunixsocket-windows10-1.8-amd64.so, libjunixsocket-windows10-1.5-amd64.so]

Is there a chance to have junitsocket support Windows?
Because with Docker for Windows more and more developers will switch to Windows.

Thanks in advance.

As far as I know there won't be a chance to make Unix sockets work on Windows. Windows knows a concept of named pipes, similar, but not interoperable to Unix sockets. Consequently, junixsocket wouldn't be the correct library on Windows.

How do you connect from Gradle to Docker?

Thanks for your response!

Since the bmuschko/gradle-docker-plugin uses docker-java internally, I suggest you to follow the existing issue at docker-java/docker-java#765 - maybe you could leave a note there to increase awareness.

Time flies!

AF_UNIX is now available on Windows 10. https://blogs.msdn.microsoft.com/commandline/2017/12/19/af_unix-comes-to-windows/

However, I do not have the resources to actively work on supporting this platform. Feel free to provide a pull request.

Look what happened. With cross-compilation support introduced in junixsocket 2.2, we can now support junixsocket on Windows 10! (It required some effort, but not as much as anticipated)

Please download junixsocket 2.2.0 and verify :)

Regarding AF_UNIX on Windows for Docker clients there's now moby/moby#36442 the next step to be resolved (and a whole rabbit hole with Golang support, etc.) ;)
... nevertheless thanks for adding Windows support to junixsocket!

Hi @kohlschuetter

Thanks for adding Windows 10 support. I was having some issues using it with another C program, and so was inspecting the C code for org_newsclub_net_unix_NativeUnixSocket.c and noticed something unusual:

The #ifdef referenced here has an else here and an endif here at the bottom of the function.

Is that intentional?

The reason I ask is that there's multiple #ifdef _WIN32 inside that else block, which makes it seem like you expect those parts of the code to be compiled on windows (e.g. avoiding the stat and chmod)
