Is it possible that vim9 release is disfunctional with coc.nvim?

Is it possible that the vim9 release is dysfunctional with coc.nvim?

Homebrew released vim9 2 days ago, and since then, whenever I have a file like a .json document or a .tf HCL document loaded and when I am in Insert or Append mode, I have an issue with inserting a newline. When I press RETURN to start a new line, the CPU will go to 100% on a single core, and VIM will appear locked up until I hit C-c. If I remove coc.nvim, this no longer happens.

I am just wondering. I've not had a lot of time to debug.

What's your coc.nvim :CocInfo?

Tested with coc.nvim master/release on Vim 9.0, works ok

vim version: VIM - Vi IMproved 9.0 9000000¬
node version: v16.15.1¬
coc.nvim version: 0.0.81-2522eee5 2022-06-14 19:03:29 +0800¬
coc.nvim directory: /Users/fannheyward/.local/share/nvim/plugged/coc.nvim

Definitely not master :). Running from release since day 1 of using coc.nvim.

I guess I should give that a shot.

Ok bumped up to master and the problem seems to be gone!

Looks like a very large number of commits between master and release!

[fannheyward]

You don't need to care about the number of commits between master and release. The release branch was built on 2522eee.

Actually, I have to retract my statement about the problem being gone. It's just manifesting differently. I'm not able to identify the specific causes now, but if the conditions are right, attempting to end a line and start a new line will cause the CPU to peg to 99/10-0 (1 core) and I have to C-c to regain control of the vim9.0.0 process. Ill have to put some more time into debugging sometime in the near future.

To see what function block your vim, checkout :h :profile.
Could be something get slow during coc#on_enter(), try avoid it to see if it helps.

I'll check it out! I do miss coc-nvim in my toolset of late...
