std.net.StreamServer.accept cannot handle SO_(SND|RCV)TIMEO sockopts

[stef]

i'm running into this line in my code: https://github.com/ziglang/zig/blob/master/lib/std/net.zig#L1701 - accept() getting a WouldBlock error, since i did not set std.io.is_async, but what i did was to do a setsockopt for SO_(SND|RCV)TIMEO which sets a timeout on the socket...

i don't really want to set the socket to nonblocking. i just want to regularly return if there is no incoming connection, but i'm ok to have a few seconds timeouts on that...

i lifted the code from 0.6.0 into my own sources and modified it to look like this:

pub fn accept(self: *net.StreamServer) !net.StreamServer.Connection {
    const accept_flags = os.SOCK_CLOEXEC;
    var accepted_addr: net.Address = undefined;
    var adr_len: os.socklen_t = @sizeOf(net.Address);
    if (os.accept4(self.sockfd.?, &accepted_addr.any, &adr_len, accept_flags)) |fd| {
        return net.StreamServer.Connection{
            .file = fs.File{
                .handle = fd,
                .io_mode = std.io.mode,
            },
            .address = accepted_addr,
        };
    } else |err| return err;
}
