`go to reference` causes high cpu usage and vim gets stuck

sify21 commented 2 years ago

Result from CocInfo

vim version: VIM - Vi IMproved 9.0 9000000 node version: v16.9.1 coc.nvim version: 0.0.81-2522eee5 2022-06-14 19:03:29 +0800 coc.nvim directory: /Users/sifangyuan/.vim/plugged/coc.nvim term: Apple_Terminal platform: darwin

Describe the bug

I use coc-go and coc-rust-analyzer. Recently I upgraded vim and all its plugins and coc plugins to latest version. After the upgrade, iterating through the location list of go to reference becomes very slow, vim consumes more cpu and gets stuck.

If I close the list preview (by pressing p), iterating through the location list is smooth as before.

I don't know if this is a bug related to vim 9 on mac.

Reproduce the bug

We will close your issue when you don't provide minimal vimrc and we can't reproduce it

Create file mini.vim with：

if empty(glob('~/.vim/autoload/plug.vim'))
  silent !curl -fLo ~/.vim/autoload/plug.vim --create-dirs
    \ https://raw.githubusercontent.com/junegunn/vim-plug/master/plug.vim
  autocmd VimEnter * PlugInstall --sync | source $MYVIMRC
endif
call plug#begin('~/.vim/plugged')

high cpu usage of vim in top WechatIMG38

@fannheyward could you try reqwest source file src/redirect.rs, and go to reference on ActionKind? vim gets stuck every time when I get to location 11.

I have the same problem both on macOS and Debian (with linuxbrew vim), and my vim config is on https://github.com/sjx95/.vim

When I open any .go files and call go to reference, the vim gets stuck.

BTW I tried to compile vim82 on Debian, and go to reference works as normal with the same vim config.

@fannheyward I've been having the same issue with Typescript and Clojure, and finally figured out that it occurs when set foldmethod=syntax is present. The config that @sjx95 shared also has this setting, as does the config in the OP.

@fannheyward It really works by removing set foldmethod=syntax, thanks!!

@fannheyward I also confirm that commenting out set foldmethod=syntax solves the problem. Both vim-8 and vim-9 respond faster without the setting.

@fannheyward Are you sure this should be closed? The foldmethod should not cause Vim to freeze up when calling <plug>(coc-references).
