IntelliSense database gets into bad state after extension update

[KnewHow]

Bug type: Debugger

Describe the bug

• OS and Version: Ubuntu 20.04
• VS Code Version: 1.60.1 83bd43bc519d15e50c4272c6cf5c1479df196a4d x64
• C/C++ Extension Version: v1.7.0-insiders
• Other extensions you installed (and if the issue persists after disabling them): CMake and CMake Tool and so on.
• A clear and concise description of what the bug is. When I use this function [Find All References] to find a method where it is called, the result is none! But it is good at v1.6.0

To Reproduce Please include a code sample and launch.json configuration. Steps to reproduce the behavior:

1. Find a any method in a cpp class
2. click right and choose the [Find all References] function
3. It will tell you no results.
4. It is very disappoint!

Additional context I want to use v1.6.0, but the VSCODE always auto install the v1.7.0-insiders for me. But the v1.7.0-insiders has a bug for [Find all References] when I'm viewing code! I don't how to close the auto install. If you can control it, please give me a switch to close auto install function. Or you can recommend new version for me, I can choose whether to install it, don't auto install it. I feel very uncomfortable!

@KnewHow Could you try 1.7.0-insiders2 and see if the issue is resolved? If the issue still persists, could you provide the following:

• Small sample code
• While reproducing the issue, get logs from the language server. See instructions https://code.visualstudio.com/docs/cpp/enable-logging-cpp#_enable-logging-for-the-language-server on how to get logs from the language server.

If you would like to disable auto-update to insiders, set C_Cpp.updateChannel to "Default"

[KnewHow]

I would, but How can I install 1.7.0-insiders2?

If you have C_Cpp.updateChannel set to "Insiders", then it should automatically update to 1.7.0-insiders2.

[KnewHow]

OK! I will try it, if with some problem, I will report to you. Thanks your team give us a so convenient plugin! All the best!

As you see, the function [SinTheta] has been called by below functions several times. But when I use [Find All references] for this function to find where the function is called. However, there are no results !

and you can find the source code file in: https://github.com/mmp/pbrt-v3/blob/master/src/core/reflection.h

I also try some others functions to use it. But I find sometimes it will work well, but sometimes is disappoint. I don't know why.

I'll see if someone on our team can repro this.

@KnewHow We were able to reproduce this by first installing 1.6.0 and then updating to 1.7.0-insiders2 while a project was open.

A workaround to fix the issue for now is to reset the IntelliSense database. Perhaps the database got corrupted during the update. Could you try resetting the database and see if it fixes the issue on 1.7.0-insiders2? To reset the database, run the command C/C++: Reset IntelliSense Database from the VS Code command palette.

[KnewHow]

OK, I have tested it, the problem has been solved in version 1.7.0. Thank you, All the best.

But I find a phenomenon, when I open some projects that I used vscode to open them severals weeks ago, I must need to this C/C++: Reset IntelliSense Database operation, otherwise the function of [Find all References] will show no results. It is a little disappointing.

It seems that the cause of this issue is when there is an update to the C++ extension, then the IntelliSense database may get into a bad state. The workaround for now is to reset the IntelliSense database until we figure out how the database is getting into a bad state.
