Vscode-eslint: eslint server crashed 5 times in the last 3 minutes. the server will not be restarted.

[iosky]

[iosky]

first of all , I have globally instanlled eslint by npm

[dbaeumer]

@iosky anything special in the ESLint Output channel. What happens if you execute eslint from a terminal on the same file / project. Does it work correctly ?

[iosky]

this has been tested ,and it works.

[dbaeumer]

Anything in the ESLint Output Channel (e.g. OUTPUT tab -> ESLint drop down). Can you provide the sample as a GitHub repository I can clone so that I can investigate ?

Does ESLint work for you on other projects or does it always fail ?

[iosky]

once the vscode is restarted, it will report this problem, but in terminal, eslint works normally

[iosky]

during this time, I also completely uninstall be vscode and then reinstall it, but it will also report this error.

[iosky]

this is my a test library for my local installation of eslint, but it's still wrong.
[email protected]:iosky/eslintTest.git

[dbaeumer]

The link in this comment https://github.com/Microsoft/vscode-eslint/issues/437#issuecomment-376545719 doesn't point to a valid GitHub repository. Can you please provide the correct link.

And is there anything in the ESLint Output Channel.

[iosky]

eslint does not run, so nothing appears in the output box

[iosky]

[email protected]:iosky/eslintTest.git
isn't this repository ok ?

[dbaeumer]

Now the link doesn't work. The correct one is https://github.com/iosky/eslintTest :-)

[dbaeumer]

The repository doesn't work for me. It contains a references to

[iosky]

Now, the repository is work, but eslint doesn't run in vscode
https://github.com/iosky/eslintTest.git

[dbaeumer]

I cloned the repository again and I still get

[dbaeumer]

After removing the eslint options from the setting everything works for me as expected:

[dbaeumer]

Is there anything in the ESLint Output Channel? And can you enable logging to see when the server crashes "eslint.trace.server": "verbose"

[iosky]

I set, but no thing in the output channel, I wonder if my local setting affects eslint server. Is there a requirement on node's path setting? I have changed the global installation path of node before

[coyle5280]

I am having the same issue with vs code and eslint. Eslint server crashes everytime I open VS code. I have added eslint.trace.server": "verbose to settings and unfortunately when the eslint server crashes the output channel also disappears. I have no other eslint options in settings. I have tried uninstalling and reinstalling eslint, vscode, eslint vs code extension. Same error appears every time. This problem surfaced very recently. Was working only a few days ago. .eslintrc.js is working for others in VS Code with same versions. Any help would be appreciated.

[dbaeumer]

I created a special vsix that disables the disposing of the output channel to see if we get better tracing when the server crashes. To install the vsix do the following:

• download this zip:
  vscode-eslint-1.4.8.zip
• change the extension to vsix
• uninstall the eslint extension
• install the eslint extension from the downloaded vsix. To do so open VS Code and the F1 > Install from VSIX
• provide me with the output when the server crashes.

@coyle5280 can you think of anything that makes your machine different to others. As said I am not able to reproduce this.

[iosky]

I did，But，when the server crashes， there is nothing in the output panel except the error alert

[dbaeumer]

@iosky strange. Could you do the following: before opening the JS file open the developer console via Help > Toggle Developer Tools. Then open the JS file that makes the server crash. Is there anything in the console of the developer tools ?

[iosky]

[coyle5280]

@dbaeumer I can't think of anything that I have changed or installed over the last few days that would make my machine different from my colleagues.
Here is the output from ESlisnt:

My console output is the same as @iosky

Here is a little info on what I am running. Maybe it will help maybe not...

ESLint Version: v4.19.1
Global node version: v8.11.1

[rheng001]

I am having the same problem with the same setup as @iosky and @coyle5280

[dbaeumer]

Actually I have no idea why this is happening. Could someone of you try to debug this ? Do the following:

• clone this repository
• cd into the directory
• npm install
• npm run compile
• open the workspace with VS Code.
• go to client\srcextension.ts
• on line 361 change inspect to inspect-brk
• Run Task > npm run watch:client
• open debug panel and select Lanuch Extension. Press the run button
• in the start Code instance select the workspace the makes the eslint server crash
• go back to the Code instance that contains the eslint code
• debug panel
• select Attach to server and press the run button. This should break in electronForkStart.js
• open server/out/eslintServer.js
• set a breakpoint at the top of the file
• press continue
• step through the eslintServer.js

I guess it bails out pretty early on one of the require calls. Let me know where it happens.

[coyle5280]

@dbaeumer Sorry I have not been able to get to those steps yet but I will soon. Hopefully tomorrow the 11th. Will post back then. Thanks!

[coyle5280]

@dbaeumer I followed the steps you have listed above and was able to step through the file eslintServer.js. Unfortunately I did not come across any errors. Everything seems to proceed correctly as I step through the program. Any ideas? Or anything that I need to look for that i might be missing.

[dbaeumer]

@coyle5280 thanks for doing this. That indicates that it doesn't fail when the initial modules are loaded. Can you try setting a breakpiont at line 244 (content library = require(path);) and see if something wired happens there?

[dbaeumer]

And do you have any special firewall or proxy setup which might terminate the connection between the extension host and the ESLint server?

Happy Coding!

[coyle5280]

OK so i had to go out of town for work and came back sick but I am back today and will see what is happening at line 244. I will post back shortly.

[coyle5280]

@dbaeumer I do not have any firewalls or proxies setup that I am aware of. I placed several break points on and around line 244 but the program never halted at those locations.

[dbaeumer]

Reopening issue.

[dbaeumer]

Then we need to set more breakpoints. Can you set one into the process.exit handler on line 168 and capture the exception ?

[coyle5280]

When stepping through eslintServer.js I am immediately taken to the .ts version. I placed break points on line 168 in file eslintServer.js and line 297 in eslintServer.ts. None of the break points inside the new exit function are hit. I can break at the line const nodeExit = process.exit; at line 295. I also turned off all firewalls to make sure that was not causing any issues and it did not have any impact of the eslint failure. (Yes I turned them back on :) )

[dbaeumer]

@coyle5280 This is really strange. I attached a new vsix with some improved error handling.

vscode-eslint-1.4.8.zip

Can you install the vsix using the steps from here: https://github.com/Microsoft/vscode-eslint/issues/437#issuecomment-379174799 and let me know if there is any special output in the ESLint Output channel.

[coyle5280]

@dbaeumer I downloaded the new extension and reran. The output in the console does not appear to have changed any . Below is a picture. I downloaded and installed the extension twice to make sure that I was getting the newer version.

[dbaeumer]

I start to think that something else closes the connection. The server is not hitting the process.exit method nor does not report any uncaught exceptions.

The server exits itself if the connection closes and the client then restarts the server. This could exactly produce the output. I need to think how to best log this to verify this assumption.

I am out for a week. So please be patient.

[coyle5280]

Ok thanks for the help. One interesting thing to note. Not sure if it matters but I removed all of my eslint node modules and I get the same output from the eslint server. I was expecting to get a message about eslint not being installed but that was not the case. Again not sure if that matters but it might indicate that for some reason the plugin is not finding the eslint module installed globally. Let me know what i can do to help.

[dbaeumer]

@coyle5280 the plugin will complain in that case. I suspect that the server even has not the change to print that message :-(

[dbaeumer]

After that has happened can you run code --status from a terminal. I am wondering if the servers actually don't crash and the client simply looses the connection to the server?

[coyle5280]

@dbaeumer Here is a pic of the code --status output

[dbaeumer]

OK. That shows that the processes actually die. May be it would work the best if we try to debug this directly on our machine. Would this be something we could do using a screen sharing session?

[coyle5280]

Yeah. I am open to that. Do you want to send me an email and we can setup a time and method for the screen sharing? You can email me at [email protected]. Again thanks for the help.

[coyle5280]

Not sure if this is related but I did notice that this error was being posted in the Log(Window) about the same time as the eslint server error appearing. Again not sure if its related.

[dbaeumer]

I think this is a follow up error of the server going down.

I got the same problem with that while I update my vscode-insider version coincidentally.
I try to install eslint locally but still crash like this.

my setting refer eslint:

my vscode info:

ESLint Version: v4.19.1
Global npm version: v6.1.0
Global yarn version: v1.8.0-20180525.0727
Global node version: v10.3.0

[dbaeumer]

@nic611 do I understand you correctly:

• the workspace worked before
• you updated VS Code
• now ESLint always crashes when you open it on that workspace

[nic611]

@dbaeumer yes, but only happened when I work with vscode (win), not happened in mac.

[dbaeumer]

@nic611 would you be able to share the project with me, best in a cloneable GitHub repository.

[nic611]

@dbaeumer I try it in vscode stable version, no problem with that. So I guess the insider version cause that.Hope it will be sovled soon(^_^).

[dbaeumer]

@nic611 since everything works for me without problems in the insider and the ESLint extension is independent of insider / stable I would be still interested in being able to reproduce this. Any chance you could share your code.

[majesnix]

I also got this problem.

I had a pair programming / debugging session with @coyle5280 last night (thanks again for doing this with me) and we were able to track this down. The ESLint server process basically crashes in the native npm module child_process when the server calls spwanSync. I have no idea yet why this is happening on your machines (since it doesn't on most of the others) but I will prepare a small test program to see if we can get more output about why this is happening.

[dbaeumer]

Attached a new version of the eslint extension. Follow the steps from here https://github.com/Microsoft/vscode-eslint/issues/437#issuecomment-379174799 on how to install it. Can all of you give it a try and let me know if ESLint works for you again:

vscode-eslint-1.4.11.zip

[majesnix]

Works for me 👍

[nic611]

it works!! Thanks a lot @dbaeumer :+1:

[dbaeumer]

Great to hear that this fixes your problem. Will release a new version this week.

[coyle5280]

@dbaeumer Working here again.....thanks!!

[dbaeumer]

@coyle5280 thank you for helping me to track this down.

[joshunger]

@dbaeumer what version is this fixed in? I'm seeing this in 1.4.12. 😢

[dbaeumer]

My fix is in 1.4.12

Can you enable tracing to see if the server crashes at a comparable location for you. Set "eslint.trace.server": "verbose" and provide me with the content of the ESLint output channel.

[dbaeumer]

Additional question: are you using npm or yarn?

[joshunger]

I'm using yarn. If you want me to create a separate issue please let me know. Thanks.

@joshunger actually the server crashes at a different location for you. Would you be willing to debug this since I am not able to reproduce this.

[joshunger]

Yes you bet where can I find debugging instructions? Contributing.md?

[dbaeumer]

Thanks. Here are the instructions:

• clone this repository
• cd into the directory
• npm install
• npm run compile
• open the workspace with VS Code.
• go to client\srcextension.ts
• on line 340 change inspect to inspect-brk
• Run Task > npm run watch:client
• open debug panel and select Lanuch Extension. Press the run button
• in the started Code instance select the workspace that makes the eslint server crash
• go back to the Code instance that contains the eslint code
• debug panel
• select Attach to server and press the run button. This should break in electronForkStart.js
• open server/out/eslintServer.js
• set a breakpoint at the top of the file
• press continue
• open server\node_modules\vscode-languageserver\libfiles.js
• set a breakpoint at line 133
• press run
• now step through the code

Let me know where the process actually crashes.

[joshunger]

When I select Attach to server and press the run button I see the following dialog -

[dbaeumer]

That is strange. Did you see the server crash output before connecting.
