Add JDK built-in support for UDS on Java 16+ #8314

sarahchen6 · 2025-01-30T18:04:44Z

What Does This Do

This PR continues on #8197 to add support for timeouts. Instead of using Channels.newInputStream, we use NIO selectors so that we can read with a timeout. Also included is a test for timeout support.

Motivation

For Java 16+, we want to replace our use of the third party library jnr-unixsocket with JDK's built-in support for unix domain sockets (UDS).

Additional Notes

Run test with ./gradlew :utils:socket-utils:test -PtestJvm=17.

+    }

+    return new InputStream() {
+      private final ByteBuffer buffer = ByteBuffer.allocate(256);


Is there a better number than 256 for allocation?

I would suggest 8192 as a reasonable default for the socket buffer size.

In a followup PR we can consider overriding the setSendBufferSize and setReceiveBufferSize Socket methods and map them to call setOption on the SocketChannel using SO_SNDBUF and SO_RCVBUF respectively.

If you save any set values as a class member then you could also implement the getReceiveBufferSize / getSendBufferSize Socket methods. That would also let you set the stream buffer size to the maximum of these two sizes (defaulting to 8192 if neither are set.)

Following up on this with #8692 :)

LGTM - just some minor comments

We should also do some benchmarking before merging
