High CPU overload after update to VSCode 1.14.0

[onury]

• VSCode Version: 1.14.0
• OS Version: macOS Sierra 10.12.5

Steps to Reproduce:

1. Just open a project. (even without extensions) and Code Helper CPU usage goes too high.

Reproduces without extensions: Yes

Arguments of Code Helper process:

/Applications/Visual Studio Code.app/Contents/Frameworks/Code Helper.app/Contents/MacOS/Code Helper /Applications/Visual Studio Code.app/Contents/Resources/app/extensions/typescript/out/utils/electronForkStart /Applications/Visual Studio Code.app/Contents/Resources/app/extensions/node_modules/typescript/lib/tsserver.js --useSingleInferredProject --enableTelemetry --cancellationPipeName /var/folders/c_/gkwddkyn6vs5nkj9cyvf0m8w0000gn/T/vscode-tscancellation-aefeee28373a85d83ef1.sock* --npmLocation "/usr/local/bin/npm"

EDIT: Also, Code Helper will not quit after quitting VSCode. I have to force-kill everytime.

Ditto, 1.14 is absolutely murdering my CPU.

@timosaikkonen Could you check which process and with which arguments this is?

@onury 's command line shows the tsserver.

This is killing my productivity, absolutely unusable. Is there a way to switch to previous version until you release fix for this ?

[timosaikkonen]

@chrmarti Damn, didn't think to check that before downgrading. Having too chaotic a day to troubleshoot this further today but I suspect it's tsserver as well, since I'm working on TS projects too.

@csreddy You can grab the previous version from https://code.visualstudio.com/updates/v1_13

[csreddy]

@timosaikkonen thank you!

Can confirm this is also happening on Windows 10. Strikes intermittently and some of the processes will chew about more than 25% of CPU locking up VS Code entirely for a minute or so.

For anyone running into issues with the VSCode 1.14: you probably don't need to downgrade VSCode, just the TypeScript version. Here are the instructions on that. We previously shipped with TS 2.3.4 so you'll want to try installing that version locally and using it in your workspace

---

To help us investigate the CPU usage issue, please try collecting the TS Server log:

1. Set "typescript.tsserver.log": "verbose"
2. Restart VSCode
3. Reproduce the issue
4. Run the Open TSServer log File command and view the tsserver.log file

If you can share the ts log file I can take a look through them to see if anything stands out

⚠️Warning: The TypeScript log may include information from your workspace, including file paths and source code. If you have any concerns about posting this publicly on Github, just let me know and we can arrange something else. On our side, we only use these logs to investigate issues like this

@mjbvz Having the same issue: vscode lagging and taking up to 25% CPU.
here is my TSlog: https://pastebin.com/MfP4viaV

[onury]

@mjbvz downgrading typescript version to 2.3.4 fixes it for now.

same here, setting to use workspace version of typescript (2.3.4) didn't help

I'm having the same problem and was using the same TS version (2.2.1) as I was using with VSCode version 1.13.1, which does not exhibit this problem.
