It's bug of neovim, when there is a job using rpc, the CursorHoldI event not triggered as expected.
You got this bug when you have any neovim remote plugin installed.

[glepnir]

这是neovim的错误，当有一个作业使用时rpc，CursorHoldI事件没有按预期触发。
如果安装了任何neovim远程插件，就会遇到此错误。

yeah， i UpdateRemotePlugin for denite 。Is there any way to fix it?

[chemzqm]

Make coc listen to neovim's socket could avoid this problem, but that would cause other bugs like it won't work in nested neovim.

[glepnir]

Whether coc can be implemented in other ways. Replace the CursorHoldI

[chemzqm]

It's not caused by coc using CursorHoldI, it happens when rpc channel is created.
You can make vim-gitgutter to implement CursorHoldI itself, instead of relay on vim's autocmd.

[glepnir]

To implement CurorHoldI, I don't have any good ideas, it will increase the complexity, and the author of vim-gitgutter doesn't want to do this.

[glepnir]

@chemzqm wow you add support for it?

[glepnir]

it works well thanks alot

[JulioJu]

it works well thanks alot

@taigacute I continue to have the bug.

Until fix of https://github.com/neovim/neovim/issues/3757 , I've found a workaround.
I trigger :GitGutterDisable | GitGutterEnable and both column signs of GitGutter and coc appears. Have you another workaround ?

[JulioJu]

@taigacute the best solution is to use ALE for diagnostics. As it, all work fine ! I have both GitGutter and diagnostics signs!

In ~/.vim/coc-settings.json add:

  "coc.preferences.diagnostic.displayByAle": true

[chemzqm]

the best solution is to use ALE for diagnostics

It's one option, neovim should fix that bug.

[chemzqm]

Seems it's fixed on neovim, I don't have this issue on master of neovim.

[glepnir]

@JulioJu i used this version NVIM v0.4.0-583-gd08692a82, it works well. before this version .i set this au TextChangedI * GitGutter,but i think its fixed on neovim new version

[zhou13]

It seems that I still have this bug. The problem persists even with

  "coc.preferences.diagnostic.displayByAle": true

Could anyone confirm it? My neovim has version NVIM v0.4.3. The problem disappears when I disable coc.

[GioF]

@zhou13 Can confirm, also have the same problem, even with

"coc.preferences.diagnostic.displayByAle": true

Was on nvim v0.3.4 because of the stable repositories from debian, removed via apt and then manually compiled via make after i cloned the repository; even on v0.5.0 it still happens. gitgutter works perfectly until i enable coc.

[GioF]

Found the source of the bug on my side: i had vim-airline-clock enabled, but once i disabled it gitgutter returned to work normally; i didn't stop to think that the gitgutter function call would happen immediatelly after the coc windows had gone away.

[zhou13]

I don't have vim-airline-clock installed. But if I disable vim-airline, then this bug disappears like magic.

[chemzqm]

That bug was fixed on neovim 0.5.0

[zhou13]

I am at NVIM v0.5.0-423-g4139678f9 that was compiled several minutes ago.

[GioF]

I don't have vim-airline-clock installed. But if I disable vim-airline, then this bug disappears like magic.

Strange. I have vim-airline installed, but except from it, no extensions. Maybe if you disable other extensions (if you have them) the bug will disappear?

[chemzqm]

I am at NVIM v0.5.0-423-g4139678f9 that was compiled several minutes ago.

Should be another issue, but I can't reproduce.

[zhou13]

I will try to provide a minimal vimrc.
