Code just continually runs, does not terminate despite connecting and sending if it can.

Dicebot told me that this is just the expected behavior. However, without the runEventLoop(), it does not terminate on Linux but it does on Windows. This is likely due to the different drivers being used. Ultimately, I'd just like it to terminate after it sends the packet while using a custom main.

The root cause is
#212. I'll look
into why it doesn't terminate even without the runEventloop().

This terminates fine for me on either Windows or Linux:

import vibe.core.net;

void main()
{
	auto udp = listenUDP(0);
	udp.connect("127.0.0.1", 31722);
	udp.send(cast(ubyte[])"Test");
}

Do you have anything in addition to this?

Alright, it terminates for me now. Not sure if it was a change or just me messing up here. However, since the change, if I have runEventLoop() toward the end, it gives me an error about releasing a TCP connection that is not owned. First of all, it's obviously a UDP connection (probably a typo in the source). Secondly, I guess I don't really understand the event loop in a VibeCustomMain application. It is blocking, and I oftentimes have a 'main loop' in my main function. Should I put this loop in a task, start up all of my tasks, and then runEventLoop()?

Thanks for all the help!

I think I may have misreported that error, as it's not coming from this source code. However, here is the full error:

It is coming from: https://github.com/Kelet/theatre/tree/master/source

Whenever it recvs, the error is generated. You can just send it a UDP packet using the source code on this thread. It could just be me doing something wrong though.

OK, should be fixed now. The assertion was simply wrong when called from
outside of a task.
