Describe your issue

If I enable the tailwindcss-intellisense extension and launch VS Code in a project directory that does not have any TailwindCSS code (AFAIK) the extension spawns a rg process that uses 1000%+ CPU.

This project is an private one that I use to manage container apps on my workstation. It has a data directory that container applications like home assistant, paperless, gitea etc use as volume mounts.

Some of these projects do have .ts and .js files in this directory so maybe it is choking on watching all of those files? Maybe the extension should check for a tailwind config and only spawn the rg process if it knows that TailwindCSS is being used in the project root?

[thecrypticace]

Looks like Dev Container's had a similar issue that they fixed / worked around: microsoft/vscode-remote-release#9738

It's not open source (that I can see) so I don't know exactly what they did to fix it but one of the comments gave me potential ideas to go on. I'll see what I can come up with.

Thanks for reporting this!

[thecrypticace]

Okay so a couple of questions:

• Are you using PNPM for any of those projects?
• If you take that manual rg command from ps and run it yourself in the same working directory without the --follow flag does it complete quickly?
• Do you know what kind of mounts you are using in Docker? Are they actual volume mounts, bindfs, or something else?
• What storage driver are the mounts using?

You're on an NVMe SSD so I doubt drive speed is not even remotely in play here. I wonder if Docker is doing something weird with those directories that causes directory listing and/or other file operations to slow down.

[robcresswell]

I think I've found something similar in my project. It's a Python data project that as part of normal operation will install tens or hundreds of node projects. There's no tailwind install or config in the project root though, is there a sensible way I can disable it? I have the plugin installed for other projects I work on 😃

[Ev357]

i think i have a similar problem. I noticed when my laptop suddenly started crashing. When i looked into my processes:

I'm using v0.0.24 with neovim (btw).

I just opened a index.vue file in an empty folder.

[zaaack]

same here

[adamhamlin]

Same issue

[BFranse]

I have the same issue happening. On the latest version (0.12.15) when enabled, it spawns tens of rg processes consuming all cpu on an M3 pro. What I did to temporarily resolve it for now, is install 0.12.11, which seems to not have this issue.

If I can provide some more info to help troubleshoot the issue, please let me know how and I'll happily provide it.

[decafdennis]

Same. After installing this extension and opening a (large) codebase that doesn't use Tailwind, it spawns many of the same process:

/Applications/Visual Studio Code.app/Contents/Resources/app/node_modules/@vscode/ripgrep/bin/rg --files --hidden --case-sensitive --no-require-git -g **/{tailwind,tailwind.config,tailwind.*.config,tailwind.config.*}.{js,cjs,ts,mjs,mts,cts} -g !**/.git -g !**/.svn -g !**/.hg -g !**/CVS -g !**/.DS_Store -g !**/Thumbs.db -g !/{**/.git,**/.svn,**/.hg,**/CVS,**/.DS_Store,**/Thumbs.db,**/.git/**,**/node_modules/**,**/.hg/**,**/.svn/**} --no-ignore --follow --no-config --no-ignore-global

The number of processes keeps growing and growing until eventually my computer becomes very unhappy.

Using version 0.12.18 of the extension and 1.96.4 of VSCode.

[thecrypticace]

So we don't spawn these processes directly. They are spawned by VSCode — likely due to registering watch patterns. But I can't think of a reason these would spawn a bunch or use 100% CPU.

@BFranse @decafdennis Would it be possible to provide access to a project that reproduces the issue (even if privately via GitHub?)

[decafdennis]

Sorry, I can't... if you have any quick pointers on how to debug, I'd be happy to try.

The extension works fine in the repo where I need it, though, so for now I'm happy to just enable it on a workspace-by-workspace basis.

Sorry, I can't. Like @decafdennis I'm happy to try and provide any info you'd need.

Edit: I was writing up all my details and wanted to attach a video, and it doesn't seem to cause issues anymore now.
It did earlier in the morning though. I did fix a settings/config thing about linting and formatting for another extension this morning, but I'm not sure if they could be related.

[thecrypticace]

By any chance does using the tailwindCSS.experimental.configFile resolves anyone's issues with the runaway ripgrep process?

I've also seen some reports in other extensions that the ripgrep process can have problems when symlinks are involved. Could that be the case here?
