In my recent tests, it appears as though it is not possible to successfully
connect via two Unix Domain sockets from one client application to one server
application.
Specifically, if I create a server which listens on a Unix Domain socket and a
client, which attempts to connect() twice, both seem to lock up. This is not the
behavior under Linux.
I will be happy to work up a minimal example if it is helpful in tracking this
down. I wanted to start by asking whether this is a known limitation and/or if
there is something about the Cygwin implementation that makes this sort of thing
very difficult.
A minimal example would be extremely helpful.
Corinna can answer questions about limitations in the current implementation.
But there is a new implementation under development. It's in the topic/af_unix
branch of the Cygwin git repository if you're interested in looking at it.
Corinna began working on this a couple years ago, and I've recently been trying
to finish it. I've made quite a bit of progress, but there's still more to do
and undoubtedly many bugs. So any test cases you have would be very useful.
