Rate Limit Exceeded Error is Hidden

[imdanielsp]

I decided to upgrade my version of Clang to 18; after removing the older version and installing the newer one, I noticed that the extension was no longer working. I immediately looked at the extension log, and nothing was being displayed, nor pop-up errors in the VSCode UI. After some digging, I decided to open the Developer Tools and found that the extension is attempting to download clangd–which is ok; I can probably provide the path to the new binary, I hope–but it was getting rate limited:

Extension console log empty:

System information Clangd version (from the log, or clangd --version):

Consider making this error more explicit by either:

• Adding something to the log
• Create a pop-up with the error
• Or both

After I finished writing this issue, I thought it might be better to label this as a Feature Request–feel free to do so if you agree.

i have been getting this error as a popup today, but what does it actually mean?

what does it actually mean?

On a high-level, it means the vscode-clangd extension is trying to make a network request to https://api.github.com/repos/clangd/clangd/releases/latest to check for or install an updated clangd binary, and the Github server is responding with a "rate limit exceeded" error.

As for why Github responds this way, I have no idea.

Note that the automatic update check can be disabled by setting "clangd.checkUpdates": false.

It's always possible to update the clangd server manually by downloading the desired version from https://github.com/clangd/clangd/releases (or another source of your choice, like https://apt.llvm.org/ for Debian-based Linux systems) and pointing the extension to it using "clangd.path".
