Vscode-eslint: Getting code actions from ''ESLint''

[h3xsoul]

Issue Type: Performance Issue

I got a performance regression after an update of VSCode insider, not sure which version was working fine, updated on 08.26.2020 - 08.27.2020. Today decided to report an issue.

I found a couple of similar problems:

https://github.com/microsoft/vscode-eslint/issues/999
https://github.com/microsoft/vscode/issues/102956

settings.json

"editor.formatOnSave": false,
"editor.codeActionsOnSave": {
    "source.fixAll": false,
    "source.fixAll.eslint": true
},

ESlint node module version: v6.8.0 (didn't change)

Extension version: 2.1.8
VS Code version: Code - Insiders 1.49.0-insider (6384e3246884694cbc34eacc70281ada15e2c7f2, 2020-08-28T16:02:16.834Z)

Without a reproducible case this is very hard to track down. Almost all cases I have seen so far result in high CPU usage in the eslint npm module itself. To verify that you could use the setting eslint.debug which prints a performance trace to the ESLint channel.

Can you provide me with a GitHub repository I can clone that demos what you are experiencing.

[h3xsoul]

@dbaeumer Unfortunately I can't share the project but let me try with debug info.

[dbaeumer]

@h3xsoul thanks. Let me know what you find out.

Happy Coding!

[timroes]

I've having the same issue on a couple of repositories regularily. One of the repositories where I can reproduce it always is EUI. Just opening that project and trying to save a file a couple of times, usually from around the 5th saving on it'll always be in that state where it's stuck in the "Getting code actions from ESLint" phase. eslint.debug does not seem to produce any helpful information for me: https://gist.github.com/timroes/9f15a78f5fc1ed1e1b3cecb94f9195d5

When I hit saving in the stuck mode, no new lines will appear in the log. I know that other people working on that repository are having the same issue, so I hope with that above repo it should be easily reproducible. I've also enabled all other checks, to make sure it's really stuck on the ESLint check and not one of the TypeScript code actions.

It seems to happen OS independent (fails at least on Linux and Mac).

Please let me know if I can provide any additional information.

cc @chandlerprall @cchaos

[dbaeumer]

@timroes actually the trace is helpful. It shows that the linting hangs in the ESLint npm library. The 2020-10-06T15:02:34.292Z eslint:linter Verify should at some point be closed with something like eslint:cli-engine Linting complete in:

[dbaeumer]

@timroes I tried to reproduce this using the repository you pointed out. Any more steps you can provide (e.g. which file to save and what to type beforehand)

[timroes]

@dbaeumer for me it happens pretty regularily. I e.g. just edited the combo_box.tsx file in a couple of places and saved it a couple of times and it got stuck. In general I don't have noticed any specific steps or actions I took, than just coding, saving and after some saves it's stuck.

[JonasBa]

Happens pretty regularly to me too, with the message ': Getting code actions from ''ESLint', 'TypeScript Importer'' (configure)' I tried disabling the ts import plugin but it didnt solve the issue.

[dbaeumer]

@timroes I tried again with the repository you provided but without any success. But I have to say I didn't make any meaningful changes. Not an expert in the code. When this happens to you the next time could you provide me with the content of the file when it gets stuck. May that helps to track this down.

[dbaeumer]

And two general question

• when this happens do you experience high CPU load ?
• @timroes would you be willing to run the extension out of source? Then we could attach a debugger when it happens and get some more insight about where it hangs?. I can provide you with instructions. It is not complicated.

[cchaos]

I can attest to @timroes' problem as I personally had the same issue with the same repository a while back. It would definitely throttle my CPU and I'd always have click "Cancel" where it would skip the auto-formatting and then save the file.

I can't remember exactly what my previous configuration in my settings file was, though something similar to what the OP pasted. I removed all of those configs and I now just have the following relevant settings:

  "editor.formatOnSave": true,
  "eslint.format.enable": true,
  "editor.defaultFormatter": "esbenp.prettier-vscode"

The editor saves and formats on save properly now.

[FloodGames]

It keeps coming up for me too since the latest releases from Eslint I guess.

[dbaeumer]

I believe all of you that you see this. But without me being able to reproduce it there is very little I can do. So if someone has steps please provide them here. Or if someone is willing to debug please ping as well. I can provide steps on how to do this.

[myasonik]

@dbaeumer Happy to debug with your guidance. I can consistently trigger the hanging issue with any change right now so I'm not sure I can provide an repro steps other than "try saving a file..."

I'll hold off making @cchaos's recommended config changes for a few days so that I don't risk changing anything before getting to the bottom of this.

[dbaeumer]

@myasonik thanks for your willingness to debug this. Highly appreciated. Here are the steps:

• clone https://github.com/microsoft/vscode-eslint.git
• cd into vscode-eslint
• run npm install
• run npm compile
• open VS Code on the workspace
• bring the debug viewlet to front
• select Launch Client
• press run button
• in the new VS Code instance that opens open the workspace you can trigger the behavior in.
• open a file that trigger ESLint validation
• go back to the first instance of VS Code
• in the debugger viewlet select Attach To Server and press the run button

When you hit the problem go back to the first instance of VS Code

• select the server in the call stack pane and press the pause button

Can you then provide me with the call stack. I will then see what additional information we can obtain to be able to reproduce this.

[timroes]

I am having "excessive saving issues", in the form that I hit "save" very very often while typing (like a couple of times per minutes). Sometimes I guess I hit it when the code is not even in a compilable state. I wonder if that could be related to that issue, because I had - while watching this behavior over the weekend - the feeling it happens more often when it's trying to reformat (prettier via eslint) in a state, where the code is not actually parseable. Sorry, haven't had the time to really debug it, but maybe @myasonik this can help reproducing this.

[myasonik]

Welp, I finally got around to this and I can't reproduce it after being able to reproduce it consistently for two days. (And I haven't touched the repo nor any settings in since then.) Banged at it for nearly an hour with no luck.

The only trace I could get is this one though it seems to just be a warning that wasn't causing any issues...

[reifnotreef]

Just stopping by to say I have this same message popup almost every time I save a .tsx file in a React project.

I tried adding/removing options from the settings.json:

  "editor.formatOnSave": true,
  "eslint.format.enable": true,
  "editor.defaultFormatter": "esbenp.prettier-vscode"

Tried enabling/disabling each of those but nothing changes the behaviour.

[dbaeumer]

@myasonik thanks a lot for trying!!

@reifnotreef can you share that repository with steps to reproduce?

[reifnotreef]

@reifnotreef can you share that repository with steps to reproduce?

Unfortunately no, it's a private work repo. My first guess is a specific setting we have but I haven't been able to find anything that would cause it in our config files etc.

[FloodGames]

At this point in time, it doesn't seem to get stuck anymore (latest vscode, eslint or just the act of upgrading did it?)

[reifnotreef]

My current, relevant, settings are:

  "editor.formatOnSave": false,
  "eslint.format.enable": false,
  "editor.defaultFormatter": "esbenp.prettier-vscode",
  "editor.codeActionsOnSave": {
    "source.fixAll": false,
    "source.organizeImports": false,
    "source.fixAll.eslint": true
  },

I did make sure that I have the latest prettier/eslint via npm i -g.
It still pops up every now and then, but it doesn't hang for nearly as long as it used to.
I have all of vs-code's formatting turned off and rely on eslint/prettier specifically.

[dbaeumer]

Can really no one share a repository with me we I can reproduce this?

[cchaos]

The repo that some of us have been having trouble with this in is https://github.com/elastic/eui

[timroes]

@cchaos @myasonik I'd be curious if it happens to you after the latest VSCode upgrade still. I've upgraded last week and worked the weekend on a project, where it didn't happen that often as in EUI, but still often enough to notice, and I haven't had a single issue ont he whole weekend in that repo. But haven't checked yet if it also disappeared for EUI, maybe one of you already tried with the new VSCode version.

[dbaeumer]

I again played with https://github.com/elastic/eui without success. @cchaos which file are you usually editing when you see this.

[h3xsoul]

@dbaeumer I started using the stable version of VSCode since the settings sync feature was added to it. But since then, nor Insider nor Stable version didn't have any issues of saving with eslint. This problem just disappeared without updating eslint dependency in repo or plugin. Couldn't reproduce it and debug since then, sorry about that. Might it be dependent on platform? I didn't see the same issue on Linux or Windows, only on Mac. Just FYI.

[dbaeumer]

@h3xsoul thanks for reaching back. I actually doubt that this is platform dependent. I still think that it hangs in some ESlint library / plugin. May be switching to a different platform installed a different version of a dependency.

[myasonik]

I got a trace!

"eslint.format.enable": true,
"editor.defaultFormatter": "esbenp.prettier-vscode",
"editor.codeActionsOnSave": { "source.fixAll": true },

[olafurkarl]

I had this issue today, which I believe was triggered by me importing an enormous javascript data file (>3MB).
Making eslint ignore the file, and then doing 'Clear Editor History' made the issue go away. Before clearing history the issue would linger.

[dbaeumer]

@myasonik thanks.

Interestingly the linter hangs on a configuration file of the repository which tries to sync get a port. I am pretty sure that this can hang the same in the terminal.

I am not sure what the ESLint extension can do about this except offering a command to reload ESLint. Does anyone know why the validation of a file in ESLint needs to load a webpack configuration file.

[chandlerprall]

Does anyone know why the validation of a file in ESLint needs to load a webpack configuration file.

Looks like its the eslint-import-resolver-webpack plugin, which makes sense. We can clean up the sync port detection in the project to avoid it when not explicitly running the dev server.

[timroes]

I've checked the other project where this happened for me. No eslint-import-resolver-webpack in there, but eslint-import-resolver-node (via react-scripts since it's a Create React App application). Maybe this is having similar problems.

[timroes]

I am not sure what the ESLint extension can do about this except offering a command to reload ESLint.

Reloading eslint would already be a huge benefit. I am so far always using the "Developer: Reload Window", but only reloading eslint would be nicer. I am wondering if there might be different plugins which can be stuck in that way and if vscode-eslint could be "more smart" about detecting those hangs independent on what crashed freezes eslint somehow? (Don't know the internals of this plugin to know if there's a possibility for this.)

I will look into providing a reload command. Detecting these cases is not easy. I will look into whether I can auto attach a debugger and then try to get a stack dump when the server becomes unresponsive for a certain time.

[timroes]

Could there be a setting like killAfter that could automatically trigger the reload after it became unresponsive for some time? This could be off by default so users not running into those problems will never be affected by it, but for us in this thread knowing we might run into it we could use it to automatically have eslint reload?

[dbaeumer]

Actually I am not a fan of this since it will not help to track down the underlying reason. I will first try to see if I can programmatically attach a debugger and then try to collect a stack trace to see why it is hanging.

[ThaJay]

It seems to happen reliably for me when I start up the editor and when create a new file in a project that has circular depedencies.

If I let it sit for 10 minutes or more, it usually comes back to a fast state.

[dbaeumer]

Circular project dependencies or files.

I started a new project to try and get to the bottom of this, and for me the hanging on code actions occurred once I tried to include this plugin: eslint-plugin-import-order-alphabetical

@eurobob, is it possible you have settings configured in your workspace or user level in VSCode to auto-organize imports in addition to the ESLint alphabetize? I was experiencing the "Getting Code Actions" hanging behavior when I had two conflicting formatters trying to organize my imports in different ways. One was an ESLint rule and the other was in my editor workspace settings. Removing one solved the hanging issue but I couldn't find a way to get both to work together.

[dbaeumer]

@eurobob can you share that setup in a repository I can clone including some source files showing the problem.

[sepehr500]

This drove me crazy for a long time. But I figured out what was happening. In my case, vscode had accidentally auto imported import { collapseTextChangeRangesAcrossMultipleVersions } from "typescript"; and I didn't notice. This is what was causing eslint to be super slow. When I removed it things were back to normal. Not why eslint is analyzing npm modules like this, but maybe we should add a flag to ignore them?

[dbaeumer]

@sepehr500 in this setup do you see a slow down when running eslint in the terminal?

[NicolasBuecher]

Hello guys, I'm running into this issue for 3 days now, in a private repo (sorry) using Typescript.

On other repos using only JS, everything works great.

As I recently switched to this TS repo, I'm not sure if the issue came with the recent Typescript support or not.
I can see in my settings.json file that I was using the depreciated eslint.validate: [typescript, typescriptreact] and I don't remember having trouble last time I used the repo.

I've to say I'm the only one of my team having the issue for now (also the only one using Windows), although we're several to use VSCode.

eslint (v7.12.1), typescript-eslint/eslint-plugin (v4.6.1) and typescript-eslint/parser (v4.6.1) are in the devDependencies, we don't use anything globally installed.

I put some dirty code in a file and when I run:

node_modules/eslint/bin/eslint.js ./src/core/Scene/Scene.ts

I get exactly what I'm expecting from the linter:

/fakePath/src/core/Scene/Scene.ts
  77:5   error  Unexpected console statement                  no-console
  78:1   error  Expected indentation of 4 spaces but found 6  @typescript-eslint/indent
  78:7   error  Unexpected console statement                  no-console
  78:23  error  Trailing spaces not allowed                   no-trailing-spaces
  79:1   error  Trailing spaces not allowed                   no-trailing-spaces

✖ 5 problems (5 errors, 0 warnings)
  3 errors and 0 warnings potentially fixable with the `--fix` option.

So I guess eslint works fine.
BUT, VSCode doesn't lint anything:

Here is the ESLint output console

    }
}

Now I systematically get the never ending pop up (and still the same output in ESLint console):

Here is all I have, sorry for not introducing any new elements to help us.

[sepehr500]

@dbaeumer I see the slowdown when running eslint in the terminal as well.

[dbaeumer]

@sepehr500 thanks.

@NicolasBuecher I think your problem is unrelated to the slowness described in these issues since ESLint is not working in your setup in the first place. Are you suing a mono repository?

[dbaeumer]

@NicolasBuecher I would still like to understand why this is happening for you. Would you be able to distil a reproducible case or share the project with me using another channel than a public GitHub repository?

[NicolasBuecher]

@NicolasBuecher I think your problem is unrelated to the slowness described in these issues since ESLint is not working in your setup in the first place. Are you suing a mono repository?

No it's not, there is only one package.json file at the root.
But I can tell there are several .eslint.rc files.
One at the root and one in ./src. The latter contains thetypescript-eslint rules. Because only ./src dir contains TS files.

Just in case, here is the structure of the project (I opened folders with .eslint.rc inside)

If you think my problem is unrelated, maybe I should stop writing here. I posted as I saw people saying being stuck, not only slowed down.

I'm sorry, I see that you read that quite everytime, but reproducing the project environment would be difficult. I'll try to play with VSCode and ESLint versions. As I'm the only one of my team experiencing that, I have to spot a difference somewhere and I'll tell you if I find something. Looks like other people in my team also have the problem, we'll come back with more info and maybe a repo if it's not just a bad eslint configuration.

[AndrejGajdos]

I had the same issue and found out it was made by glean extension. I needed to disable it.

[Goldziher]

@dbaeumer I have a repo where this can be reproduced: https://github.com/Goldziher/dtsgenerator

I forked this package and made some updates to the eslint config. I immediately started experiencing a huge regression.

To reproduce : clone, npm install, open dtsGenerator.ts and then save the file in vscode.

[Goldziher]

I suspect that the issue happens if a code base uses the typescript compiler directly - this is what is happening in the above repo.

[dbaeumer]

@Goldziher thanks for the repository. I looked at the case and I can confirm the slowness. However already the eslint command in the terminal exposes that:

node@055baf9029cf:/workspaces/dtsgenerator$ time ./node_modules/.bin/eslint src/core/dtsGenerator.ts 

real    0m10.385s
user    0m15.449s
sys     0m1.304s

So there is nothing I can do in the ESLint extension to speed this up.

Did you consider filing this against ESLint or one of the used plugins?

[Goldziher]

@dbaeumer thanks for taking the time. I can open up an issue in the typescript eslint repo.

[NicolasBuecher]

@dbaeumer You were right my problem was unrelated to this issue. In my case it was something about an async Webpack config and getPackageMetaSync from package-meta looping endlessly. Solving the latter, using a sync Webpack config and updating dependencies fixed my issue.
Thanks for your time.

[ljharb]

I'm seeing this in https://github.com/enzymejs/enzyme, while editing basically any file. I have no typescript in the project.

I'm happy to follow any debug steps.

[dbaeumer]

@ljharb I can't access the repository. Any debug steps are highly welcome.

[ljharb]

@dbaeumer whoops, mistyped the URL, fixed. i don't know what debug steps you'd like, but i'll follow any explicit instructions you provide :-)

[dbaeumer]

@ljharb which file to open to reproduce this and what to type in that file to make the error show up.

[ljharb]

Any one, but try https://github.com/enzymejs/enzyme/blob/master/packages/enzyme/ShallowWrapper.js and make any change that requires an autofix - add trailing whitespace or omit a semicolon or something.

[dbaeumer]

I am not able to reproduce this

[ljharb]

@dbaeumer the implication is that there's something in my local config that's causing the slowdown. How can i help reveal the delta?

[dbaeumer]

How is your local "editor.codeActionsOnSave" and "editor.codeActionsOnSaveTimeout" setting.

[ljharb]

    "eslint.alwaysShowStatus": true,
    "editor.codeActionsOnSave": {
        "source.fixAll.eslint": true
    },
    "eslint.lintTask.enable": true,
    "eslint.quiet": true,

and editor.codeActionsOnSaveTimeout doesn't appear.

note that because i only want to use eslint, because vscode's default formatting violates a ton of my sensibilities, i also have "format on save/paste/type" all disabled.

[dbaeumer]

@ljharb still the same result for me using the settings you provided.

[ljharb]

@dbaeumer very strange. here's my vscode version:

Version: 1.52.1

V8: 8.3.110.13-electron.0
OS: Darwin x64 20.1.0

I'm not sure what version i have of the eslint extension.

Can you confirm you lack a global install of eslint, and that you ran npm install in the repo root first? (it shouldn't be globally installed anyways) Can you confirm you have the eslint extension set to use npm? How did you install node and what version are you using? I'm using nvm and have no system node, and i don't actually know how vscode figures out which node binary to run.

What further steps can i take to help you debug this?

[probablykasper]

In some configuration where I was trying to marry svelte-preprocess, hmr, typescript and eslint, running eslint manually caused an infinite loop of printing the linting output. Just throwing it out there in case it's be related

[probablykasper]

Was able to get the Getting code actions from ''ESLint' message consistently. Hopefully it's rooted in the same issue.

1. Run npx degit NicoCevallos/svelte-template example-app (this repo)
2. Run cd ./example-app
3. Run npm install
4. Run code .
5. Install the three recommended extensions (Not sure if necessary)
6. Open, edit and save src/main.ts

[dbaeumer]

@ljharb yes, no global ESLint and I did run npm install. And the default package manage is npm. Can you try to run in a terminal the following command npm config get prefix and see if this executes fast.

VS Code comes with node and that node version is used by default. You can configure a different node version using the eslint.runtime setting.

[dbaeumer]

@probablykasper doesn't reproduce for me. Any additional hints about your configuration

[probablykasper]

@dbaeumer Hmm, there seems to be something that triggers the bug, but then once it's triggered, it always happens, even after reloading the window.

I tried following step 1-3, and then this:

1. Open VSCode by running code . --user-data-dir ./vscodewhatever --extensions-dir ./vscodewhateverext
2. Install the recommended extensions
3. Open src/main.ts
4. Click the "ESLlint" button in the bottom right and chose "Allow Everywhere".
5. Reload window
6. Edit and save src/main.ts
7. Open, edit and save src/App.svelte. This will make it freeze, and if you go back and edit main.ts as well (even after reloading), then that freezes too.

[ljharb]

@dbaeumer indeed (npm config get prefix is a very slow command, i removed it from nvm recently for that reason):

$ time npm config get prefix
/Users/ljharb/.nvm/versions/node/v14.15.3

real    0m0.623s
user    0m0.207s
sys 0m0.120s

interestingly enough, it's using my default nvm version, but maybe the terminal is different than what vscode-eslint uses?

[dbaeumer]

It is not super fast but it is tolerable and a slow response should only lead to one waiting dialog. What do you mean by

i removed it from nvm recently for that reason

Being able to execute the command is necessary to make the ESLint server work correctly.

[dbaeumer]

@probablykasper I was able to reproduce. The server hangs in an endless loop here:

Which does some magic deasync-promise code which is actually out of my control. I guess the code is loaded and executed via the eslint svelte plugin.

[dbaeumer]

@probablykasper actually the deasync code seems to fail on electron (the node runtime) that ships with VS Code. you can set the runtime to use to a normal node runtime and things seem to work. The setting is eslint.runtime.

[ljharb]

@dbaeumer i just meant that i refactored https://github.com/nvm-sh/nvm to no longer call npm config get prefix; its use of it is different than the eslint server. Either way tho, I'd expect that call not to change for the lifetime of a vscode run, so you should be able to cache it after running it once.

I'm not using a svelte plugin tho, so that doesn't seem like it'd be my issue :-/

Is there anything I can do locally, like step through with a debugger, that would help you figure out the cause of my problem?

[probablykasper]

@dbaeumer Apparently deasync doesn't support electron. Are you able to tell if the code is coming from the eslint-svelte plugin?

[probablykasper]

@dbaeumer Pretty sure this is the problem. Shouldn't have anything to do with vscode-eslint then.

[dbaeumer]

@probablykasper yes, when debugging the stack trace came out of svelte plugin. And thanks for finding these other issues.

[dbaeumer]

@ljharb I only call the once per loaded ESLint library version. So if you only have one version one call :-).

If you be able to debug this it would be a big help:

• clone this repository
• npm install
• open it in VS Code
• Run the launch config Launch Client
• open the workspace that shows the behavior
• open a file
• Run the launch config Attach to Server
• You can break the server and see where it is running right now.
