I am having trouble using abstract sockets on Linux.
Here is sample python code that works, which works:
ptm_sockname = "\0/var/run/ptmd.socket"
sock = socket.socket(socket.AF_UNIX, socket.SOCK_STREAM)
sock.connect(ptm_sockname)
sock.setblocking(1)
sock.sendall('get-status detail')
Similar code in D, which does not work:
string socket_name = "\0/var/run/ptmd.socket";
auto address = new UnixAddress(socket_name);
auto sock = new Socket(AddressFamily.UNIX, SocketType.STREAM);
scope(exit) sock.close();
sock.blocking = true;
sock.connect(address);
sock.send("get-status detail");
This is the equivalent with socat, which works:
$ echo "get-status detail" | socat -
ABSTRACT-CLIENT:/var/run/ptmd.socket
My test D program exits on connect:
std.socket.SocketOSException@runtime/phobos/std/socket.d(2674): Unable
to connect socket: Connection refused
Any pointers?
I've found an old example of mine, which uses abstract sockets.
Apparently, it was a concurrency experiment as well. Just translated
from Turkish to English:

One difference I see is that mine doesn't set blocking. You can use it
like this:
1) Start it as a server:
./deneme --role=server
2) Start as many clients as needed:
./deneme --role=client

P.S. And here is the original Turkish version:
