codex acp adapter after closing neovim still running

[euri10]

hello, I'm just wondering if there could be an issue with closing acp adapters, in particular codex-acp, let me try to explain:

if you open a chat, select codex then entirely close neovim, the codex-acp binary still pops up running:

when using claude, I wasnt able to reproduce. I wasnt also with copilot acp

so could this be a codecompanion issue or maybe a codex-acp one since it seems to appear just with codex but I wasnt able to find something interesting in their issues.. ?

Possible cause:

codecompanion.nvim/lua/codecompanion/acp/init.lua

Line 532 in 57989ac

assert(self._state.handle):kill(9)

Killing the process with SIGKILL prevents it from graceful shutdown (forwarding the signal to the child processes, etc.). I see the same issue with agents installed via Volta, which runs node app as its child process.

nice catch, 15 might be preferable indeed

I tried changing it and it doenst seem to make a difference

https://github.com/neovim/neovim/issues/39552?utm_source=chatgpt.com might be a related, the codex-acp is installed through npm while it's a rust binary, if you install it from source with cargo install --path . it doesnt happen
