Description

Environment
  • OS and Version: Debian 12
  • VS Code Version: 1.85.1
  • C/C++ Extension Version: 1.18.5
Bug Summary and Steps to Reproduce

Bug Summary:
Extension seems to cause continuous polling of the workspace config directory (.vscode/ on Linux)

Steps to reproduce:

  1. Have extension enabled
  2. run sudo strace -f -t -e trace=file -p <vscode_pid>
  3. see disk access

Expected behavior:
To not have extraneous access to this directory.

Configuration and Logs

After doing an extension troubleshoot from the vscode help (bisecting the loaded extensions) this extension ended up being the culprit of the extensive disk access.

For now I have this extension completely disabled.

Research direction

Reproduce the issue with the C/C++ extension enabled by tracing the VS Code process with strace -f -t -e trace=file and observing access to the workspace .vscode/ directory. Compare this with the extension disabled or after extension bisecting; done means the extension no longer causes continuous extraneous polling of that directory.
