Can't find way to set WebSocket connect timeout

[CoderNate]

I've copied the WebSocket code into my project to work around this but figured I should still mention it.

Ubuntu 20 on WSL2
I have a program like this:

/+ dub.sdl:
dependency "arsd-official:http" version="~>10.9.8"
+/

import arsd.http2: WebSocket, Uri;
import std.stdio: writeln;

void main(string[] args) {
        auto ws = new WebSocket(Uri(args[1]));
        ws.connect();
        writeln("Connected!");
}

If I try to connect to a port with nothing listening it takes over 2 minutes to time out:

$ time dub run --single websocket_test.d -- ws://192.168.1.141:27985
arsd-official:http 10.9.8: target for configuration "with_openssl" is up to date.
websocket_test ~master: target for configuration "application" is up to date.
To force a rebuild of up-to-date targets, run again with --force.
Running websocket_test wss://192.168.1.141:27985
std.socket.SocketOSException@std/socket.d(2852): Unable to connect socket: Connection timed out

Program exited with code 1

sys     0m0.030s

On Windows it times out in a couple seconds. Maybe there's a way to change the socket defaults for the process somehow but it would be nice if the WebSocket had a config option for it since its underlying Socket is private; or at least having a hard-coded timeout that's shorter would be good. Modifying the socket's send timeout by adding this to the WebSocket constructor:

socket.setOption(SocketOptionLevel.SOCKET, SocketOption.SNDTIMEO, 5.seconds);

results in std.socket.SocketOSException@std/socket.d(2852): Unable to connect socket: Operation now in progress after 7 seconds. Maybe there's a fancier way using select or something though.

Thanks!

There's a second argument for the constructor of type Config:

http://arsd-official.dpldocs.info/arsd.http2.WebSocket.Config.html

Which has a member timeoutFromInactivity:

.......oooh but that doesn't apply for the connect step. So there's the bug lemme see about fixing that.

Just pushed a thing to master, if you wanna grab that and run some tests I think that fixes it so the timeout from inactivity config setting is respected.

I plan on rewriting this under my new async system at some point in the next few months, when I can find the time in between other work, but this should work for now.

Sorry yeah I forgot to mention that part.

I tried out that fix and it works. Thanks!
