Description

Problem: When a .ejs file is saved, the CPU usage rises to 99%.

How to reproduce:

  • Create a .ejs file
  • Change something in it and save it

Evidence that this extension has something to do with it: I disabled all the other VSCode extensions and the issue does not happen, enabling only this one causes the problem, enabling any other plugin does not.

Running ps aux | grep 32942 returns: /Downloads/Visual Studio Code.app/Contents/Frameworks/Code Helper.app/Contents/MacOS/Code Helper /Downloads/Visual Studio Code.app/Contents/Resources/app/out/bootstrap --type=extensionHost

(being 32942 the PID of a Code Helper task is using 99% of the CPU)

VSCode version: 1.15.1 Extension version: 0.0.14

File is attached. index.ejs.zip

Contributor guide

Research direction
Profile the extension to identify the function causing high CPU when saving .ejs files. Look for recursive tag matching or event handling that triggers on save.
