Writing to Socket from Another Thread #36

Closed edqx closed 2 months ago

edqx commented 2 months ago

Perhaps this is more of an Operating System problem- on Linux, I can spawn another thread and write to a connection using any of the write methods provided. On Windows, it hangs on std.net.Stream.write:

I'm using the latest version of the library with Zig 0.13.0.

Is this a limitation of the library, of the Zig standard library, of my operating system (Windows) or of something else? What's the suggested way to send messages from a background thread?

The library doesn't do anything fancy with sockets, and I'm under the impression that this type of behavior should be fine on windows. I found this issue which I believe is what you're seeing.

Thanks for the reply, that issue looks likely to be the same since presumably the WebSocket server immediately starts reading before the other thread can start writing. I don't have time to look much into it, so if it's just Zig standard library issue then I guess I'll just use WSL2, which works fine.
