Vim: Crashes when opening large file

[fandy]

What did you do?

Opening a large SVG file crashes VSCodeVim such that it enters non-vim insert mode and you can't get back to Vim.

What did you expect to happen?

Expected large files to not crash VSCodeVim.

What happened instead?

It crashed.

Technical details:

• VSCode Version: 1.10.2
• VsCodeVim Version: 0.6.11
• OS: macOS Sierra

Just how big is this file? Multiple MB?

[fandy]

Yeah it was around 1MB. Just discovered that this issue seems to happen when I switch between multiple files quickly/ sometimes when pasting. It gets stuck in non-vim insert mode where the plugin seems to have froze and I have to restart VScode.

[rebornix]

@fandy have you ever tried disabling VIm ext and see how Code works with this file?

[ActionScripted]

Having the same issue. Taking VS Code for a spin and as part of that testing out large text files like SQL dumps. In my case it's a 52MB, 117,876-line file.

With the VSCodeVim/Vim plugin enabled it drops to a pseudo-insert mode but I cannot move the cursor or make changes to the file using the keyboard. I can scroll, click and select using the mouse in this state.

With the VSCodeVim/Vim plugin disabled VS Code works without issue with the file. You can move around, adjust text and work with the file as you'd expect.

[Chillee]

I can confirm that I can reproduce this.

It doesn't actually crash vscodevim (switching back to another tab makes it responsive again), but it definitely gets stuck on large files.

[Chillee]

One thing I've been doing as a workaround is to use the Toggle Vim Mode before opening a large file.

[femot]

I just updated to VSCode 1.16 (Windows, 64-bit version) and now it seems to work (tested /w 9MB log file).

(Interaction with other extensions seems to make it hang completely though..)

[fabrice102]

I can confirm that on large files (more than 10MB) all keys do nothing (I can still move the cursor using the mouse but I cannot do anything else). Disabling VSCodeVim solves the issue.

• VScode 1.20.1
• VSCodeVim 0.11
• macOS 10.13.3

[langolf]

Sometimes extension just freeze at svg file. Not big one, any svg file.

[jpoon]

Can you share an example SVG file that causes the freeze?

[langolf]

After you will try to insert at the end of first "path" line (where Z) I got plugin stop and high cpu

After pasting or when I'm trying to edit, Vim freezes.

Any updates on the issue?

[jerry1100]

FWIW if you're using the Auto Rename Tag extension, try disabling it.

I found an issue with that extension and long HTML tags where the closing tag isn't on the same line as the opening tag (self-closing tags are also affected). See https://github.com/VSCodeVim/Vim/issues/2003#issuecomment-439589594 for more info.

@ggomaeng I was able to reproduce the issue with your code snippet but went away after I modified the tags a bit. Could you try that out to see if it works?

Update: underlying issue on auto-rename-tag repo: https://github.com/formulahendry/vscode-auto-rename-tag/issues/32

[ggomaeng]

Yeah Auto Rename Tag seems to be the issue. This happens with not only svg files, but also when programming in React and adding props in different lines.

[jpoon]

Closing as it seems like this was a result of a different extension.
