Frequent hangs, CPU spikes in LSP
Possibly related to https://github.com/denoland/deno/issues/20136
Recently I'm having frequent CPU spikes and the LSP hangs preventing me from interacting with the editor which is highly frustrating.

The editor will hang and eventually spit out a number of output lines, sometimes 2 ("successfully..." and "Unable...") sometimes more.
Versions
vscode: 1.82.2 deno: 1.37.0 extension: occurs on both the latest 3.24.0 and the previous version (3.23.1?) os: Linux Mint 21
After a recent hang (from a stable state, all I did was press Ctrl-W twice to select all text within a pair of quotes), all this output came at once after the editor became responsive again:

Downgrading to Deno 1.36.0 did not resolve the situation. Disabling the LSP stopped the hangs and CPU spikes (obviously not a solution)
Same here on Win 11. Renaming or moving a file causes LSP to hang for quite some time, then pops up an error about OOM, and shutting down! I've seen the same list of messages as above.
This is an inexpensive HP laptop with non-upgradable 8Gig memory. Started happening when Deno Upgrade to v1.37.0.
Also the laptop fan gets very load when this happens! I've never heard the fan on this new machine prior to this.
deno 1.37.0 (release, x86_64-pc-windows-msvc) v8 11.8.172.3 typescript 5.2.2
It would if there was a bad interaction or issue with, say, the formatter or linter. I'll try downgrading the extension later tonight if that's possible.
In order to experience Bun, had installed WSL and the WSL extension in VS Code. I realize now that It was only after that that my LSP failures started. I suggest that WSL is a resource pig. No more LSP issues noticed now that I've removed WSL. I still wonder why LSP requires so much memory?
After removal of WSL I still have an issue! Renaming an 8.2mb file took more than 10 seconds. The IDE was unusable during this time. No crash or OOM was reported, but why would a file rename take such a long time?
This popup is open for more than 15 seconds on any filename change.
Is this normal?

On rename attemps the language server asks the embedded ts server to look for imports that it can rename. I guess that's taking a really long time.
Do either of you have any large dependencies that I can try to reproduce this with? I think the large TS module graph that tsc has to work with in a Deno project might be a factor.

I'm working on a new'ish Fresh project, not very far into it, and I don't think I have any large dependencies. I've pushed my WIP code here if it helps: https://github.com/cknight/kv-explorer
I've rebooted. The LSP crashed on launch of VS Code. Restarted VS Code, and it was stable for a bit (as in I could actually use the LSP for now), though now it's hanging again. Found a new error in the Output, though I got this one during a period where the LSP wasn't hanging:

The project I'm working in is only about 25 files. total It has a single external dependency in deps.ts -- export { serve } from "https://deno.land/[email protected]/http/server.ts";
Is there a way for me to print the module graph? This happens in all projects great and small where Deno is enabled.
Why would an LSP, during a file name change need100% CPU and nearly 3Gig of memory?

deno info main.ts will print your dependency tree, including sizes, etc.

@nayeemrmn I've never used a Deno.json file, so I did deno init in this small project. It produced not only a deno.json file but also a deno.lock file shown below. How did this small project get so many dependencies? Some are extremely old -- [email protected]

I guess I really don't understand Deno.
Also, why would the LSP crawl all of this for a simple file name change?
This project has a /src/ folder that has ts files that get bundled to a /dist/ folder. I use my own dev server for this. Is this all included in the file name change?
The dev-server and it's dependencies are never referenced in this project, yet some of its dependencies are in this deno.lock?
For the record I don't think that's so many it would cause the problems mentioned in this issue -- I wouldn't put too much stock in my theory above.
How did this small project get so many dependencies? Some are extremely old -- [email protected]
The old std version is used by esbuild_deno_loader 0.6.0.
After removal of WSL I still have an issue! Renaming an 8.2mb file took more than 10 seconds. The IDE was unusable during this time. No crash or OOM was reported, but why would a file rename take such a long time?
@nhrones I missed the 8.2mb part -- that's a really large file! For example our 00_typescript.js bundle is 8.1mb and is 174,000 LOC. I observed this behaviour on the regular node TS extension as well. So your case is behaving as expected.
I know it's unintuitive that the renamed file has to be scanned but I guess tsc needs to analyse the project holistically.
@nayeemrmn That's a json file with 100k user objects. The problem is, if I rename mod.ts with only several lines of code, it acts the same?
And now I can no longer enable deno in that project.
All values below are from TaskManager
When vsc opens this project with Deno disabled:
Visual Studio Code 401 MB
After a file name change 425 MB
When vsc opens this project with Deno enabled:
Visual Studio Code 2,220 MB
Deno:A secure runtime 1,759 MB
During a file name change
Visual Studio Code 4,427 MB
Deno:A secure runtime 2,899 MB
This high memory use stays this way for several minutes
never drops below
Visual Studio Code 3,370 MB
Deno:A secure runtime 2,213 MB
I've restarted my computer, and still can't get Deno enabled in this project? Any suggestions?
Okay @nhrones seems it alleviates the issue if you add the following to your VSCode settings:
{
"deno.enable": true,
"deno.disablePaths": ["<your_big_file_goes_here>.json"],
}
@nayeemrmn Yes! Thank you so much! Does this need to be an array of filePaths, or can I disable one or more folders?
"deno.disablePaths": ["./dist/"],
Does this need to be an array of filePaths, or can I disable one or more folders?
"deno.disablePaths": ["./dist/"],
You can, disabling dist folder is an exemplary use case!
I can confirm this has solved my issues of moving and renaming files with deno enabled! Much thanks again. I was about to give up on Deno, but you've created a fan.
Seems that the excess memory being consumed was related to the large json data files. In the future I'll create a data folder, and disablePath to it.
I've also disabled ./.vscode/ and a ./docs/ folder. This reduced memory consumption even more.
Again, Thanks for all your hard work.
This is still happening for me on Deno 1.37.1, however the output is somewhat different:

I'm not sure how true this holds as I've not had extensive time for development in the last day or so, but the LSP hangs primarily occurs in my types.ts file. The hang can sometimes be triggered by simply opening this file. The only major difference in this file compared to others in the project is that it has 13 exports?
Have you tried nayeemrmns fix above?
{
"deno.enable": true,
"deno.disablePaths": ["<your_file_goes_here>"],
}
I’m experiencing the same issues in a Deno project based on Slack’s starter template. There are no big files to ignore. I have to restart the language server pretty much every ~5 changes I make to a file.
