Is it bug ?

C++ extension version : 1.13.4
Hardware : M1 Pro, RAM 16 GB

Code analysis is mostly unresponsive. Even though I change the code, it can't even catch up the latest code update. This is the most notable example when I write some GRPC things. I added ; into the code but still showing the outdate error. It disappeared only after the cmd Developer: Reload Window. As you see, this screenshot is so much meme.

The flame icon in the status bar should show the status, although it's possible that "Updating IntelliSense" could block that from appearing as well. Do you see a "Running clang-tidy" status indicator when you hover over the flame icon? Are you able to click it and choose cancel and then manually re-run code analysis to get it to update? Also, if you can check if clang-tidy is running (as a process) then that would indicate if it's doing work or if there's an internal issue causing it not to run when it should.

Are using the C_Cpp.codeAnalysis.runAutomatically and C_Cpp.codeAnalysis.clangTidy.enabled both set to true or are you manually invoking it?

flame icon? i dont' find any flame icon in status bar. And yes, I enabled both what u mentioned

Does your status bar have space left? It should look something like

Does the flame appear if you manually invoke code analysis after reloading the window?

invoke ? how to invoke code analysis manually? I only clicked those 2 options u mentioned

Here is my status bar :

Now I found flame icon. The icon appears only when I invoke code analysis manually from cmd. It's not showing for normal time. Btw, is that unresponsiveness really related to the code analysis ? Or related to intellisense ?

[sean-mcmanus]

The RunAutomatically feature normally will invoke code analysis after a file is saved after an edit. If that doesn't cause the flame icon to appear, there could be some bug we may need to investigate, i.e. you could file an issue on it. If IntelliSense is blocking code analysis you would see "Updating IntelliSense" when hovering over the flame icon in addition to the code analysis message.

Flame Icon appears after saving file and disappears again. If so, it's working as u said. Let me check one more time by knowing how code analyzer works. After that, I will tell u back
