Navigation unresponsive on large files

Open sauvala opened this issue 3 years ago • 10 comments

Describe the bug Hi, I noticed that when I open a large file (I have a JSON lines file that contains over 650k lines and is close to 900MB in size) the extension makes VSCode unresponsive to navigation and editing. I cannot move caret with h/j/k/l or arrow keys and I cannot toggle insert mode on. The problem goes away when I disable the extension.

I checked the open issues but I saw only issues related to slowness when opening large files but even larger files makes the extension unusable totally. Is this a known issue and is there a workaround?

To Reproduce Steps to reproduce the behavior:

  1. Open a large file
  2. Try to navigate or switch to insert mode by pressing i
  3. VSCode/vim-extension seems to be unresponsive

Expected behavior Navigation and editing the file would work.

Environment (please complete the following information):

  • Extension (VsCodeVim) version: 1.20.2
  • VSCode version: 1.55.2
  • OS: macOS Big Sur 11.3.1

Same here. Only just started happening.

I've started seeing this as well. I get it on relatively small files. It's a ruby source file containing a multiline array and many of the lines are commented.

When vscode freezes, all keyboard input in the editor is blocked, but I can use the mouse to switch tabs, and scroll around. Running top in terminal shows me that CodeHelper is using all resources. Doing a kill -9 on that process frees things up again, and VSCode reports the failure and asks if the helper should be restarted. I say yes, it does it, and I get another 45 mins of coding done before it happens again.

I'm afraid I can't tell if it's the Vim extension or just VSCode itself.

Is there any solution?

I found no solution, and it's still happening for me.

Me too. Been experiencing this for a while. At this point, I have to disable VSCodeVim, because this happens too frequently.

Some way to fix it? or at least improve it?

What worked for me was disabling a large number of extensions. Then, I re-enabled them slowly. In the end, I'm not sure which one was causing the issue. I did not re-enable all of them.

Recently started facing this issue. Weird thing is previously it worked perfectly, but now it just completely stops working when I open a json lines file
