Long delay on :q when exiting Neovim with copilot.vim enabled, even with session counting patches — any suggestions?

Commencez par reproduire le délai d'environ 10 secondes lors de l'exécution de :q avec copilot.vim activé après une période d'inactivité, en utilisant les versions signalées de Neovim, Node.js et Linux. Examinez la gestion de VimLeavePre, le groupe d'autocommandes github_copilot et l'arrêt de copilot node-process décrit dans l'issue. Le travail est terminé lorsque le comportement de sortie bloquant a été identifié et résolu sans désactiver les fonctionnalités de Copilot, et que le résultat a été vérifié au cours d'une seule session inactive.

Hi,

I’m experiencing a significant delay (~10 seconds) when quitting Neovim (:q) with copilot.vim enabled, and this happens even with a single Neovim session after it has been idle for a while.

To mitigate this, I’ve tried:

Adding a session counter (both Lua in init.lua and Vimscript in a plugin/copilot_session.vim patch) to track how many Neovim sessions with Copilot are active.

On VimLeavePre, only calling Copilot disable and killing the copilot node process when the last session exits, skipping it otherwise to avoid the stall.

Clearing Copilot’s own VimLeavePre autocmd group (github_copilot) in all but the last session to prevent multiple shutdown hooks running.

Avoiding forcibly killing node processes except on the last session exit.

However, the stall still occurs on quit even when only one Neovim session is open and idle. The copilot node process appears to be killed during exit, and I suspect Copilot’s internal shutdown logic is blocking Neovim exit.

My questions are:

Are there known issues in copilot.vim causing blocking delays on exit after idle?

Is there an official or recommended way to make Copilot’s shutdown asynchronous or non-blocking?

How can I reliably prevent the exit delay without disabling Copilot’s essential functionality?

Are there patches, config workarounds, or plugin updates that address this problem?

Thanks in advance for any insights or help!
