Bun.connect footgun

[dlants]

Hi wallpants! Thanks so much for the work here, I found it really useful in getting started on https://github.com/dlants/magenta.nvim

I am running into an issue. I think it's probably neovim, and not bunvim, but I wanted to maybe get your input on how to go about debugging it. I documented the issue here: neovim/neovim#31793

Would appreciate any ideas you might have about how to debug this.

Thanks!

Ah turns out it is probably a bun thing, not a neovim thing:

Ah, it turns out it actually is an issue with this plugin:

See this comment: oven-sh/bun#16076 (comment)

socket.write returns the number of bytes written and doesn't buffer. That means if you write a large amount of data, the network might not send all of it, and you have to retry the unsent data when the drain callback is called. This buffering behavior is how it works in the system APIs on posix/windows.

This is very much a footgun, and we need to make this clearer in the documentation or have a way to buffer this automatically (outside of using node:net), because you're not the first person who thought this was a bug.
