Can't interrupt blocking accept about jnr-unixsocket

[felfert]

AFAIK, This is the documented behaviour of java.nio.channels.spi.AbstractInterruptibleChannel.
You need to use begin()/end() pairs, if you want to interrupt the thread.
See https://docs.oracle.com/javase/7/docs/api/java/nio/channels/spi/AbstractInterruptibleChannel.html#be

@felfert but begin/end are protected methods, so I can't call them directly. Surely it is the JNR implementation of UnixServerSocketChannel#accept that should be calling them?

[gregw]

Specifically, shouldn't this line be wrapped in begin/end pairs?

[headius]

@gregw I think you're right. Can you help us patch this?

[gregw]

@headius #25 is a PR that adds begin/end calls. It makes it a little bit better, but doesn't generally fix the problem? At least not on Linux Tile440 4.2.0-30-generic #36-Ubuntu SMP Fri Feb 26 00:58:07 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux

Fix this for 0.14.

I think the way to do accept() with an interrupt or timeout is to call select() first, check if the socket is ready, and then call accept() knowing there's a connection to accept. You could set things up so that one of the sockets passed to select() is something that a thread wanting to interrupt it could close or otherwise signal, separate from the socket you're actually trying to accept on, and you could implement a version of the api with a timeout.
