`ipch` IntelliSense cache taking up too much space. about vscode-cpptools HOT 12 CLOSED

In general I find it problematic when programs create files outside of the working directory and don't notify the user in any way and often all these remain usually after the program is uninstalled, such as configurations, caches, temporary files, etc.

Hi @H-G-Hristov,

Please see the C_Cpp.intelliSenseCachePath and C_Cpp.intelliSenseCacheSize settings and let us know if those do not provide the control you are looking for. By default, we pick a common location for cache files because that allows us to manage the total size of caches for all workspaces instead of creating GB's worth of caches per workspaceFolder.

@bobbrow Thank you for pointing these settings out.
Main main complaint is that I have been using this extension for over 5 years now and I hand no clue this is happening :) until I run out of space on my Ubuntu partition, which I created too small. It took me awhile to figure out what's was eating my space. And it turned out the cpptools extension was eathing up 30Gb.

According to the setting the cache is 5GB but in fact it was 30Gb.

So it would be nice if the extension improves the visibility of this. Maybe via message on start or something. Or maybe it can have a statistics panel, status bar entry, etc.
And if uninstalled would the extension cleanup this cache or leave it behind like so many programs do?
With so many extensions and so many settings it becomes really hard to figure out everything.

Did you intend to say Gb (lower-case 'b')? 30Gb < 5GB

If you did mean 30 GB, are you able to reproduce the issue and share some steps how to do it?

Unfortunately, we don't get to play a role in the uninstall process. That could be a feature request for VS Code.

Yes, we understand and are very much aware that learning settings in VS Code contributes to a steep learning curve for new users. We've tried to document the most important ones, but could probably do better here.

30GB as in 30 Gigabytes. Sorry.

I don't know how to reproduce it. I use VSCode to open /runtimes in https://github.com/llvm/llvm-project with a CMake preset to build libc++ and also another one to build and link to libc++ a test executable in a separate custom project. I can observe it it will happen again.

Currently:

5.5GB looks more than 5120 but it's probably not a repro.

Can you share any machine specs? Is it native Ubuntu, or WSL? x64 or Arm? Raspberry Pi or other embedded device?

It is a standard Ubuntu Desktop distro on Dell Inspiron 7567, Intel 7700HQ, 8GB RAM, the partition size is 62.1GB Total.

Thank you. So it looks like nothing out of the ordinary should be needed to reproduce this.

I think so. I have had this installation since Ubuntu 22.04 was released. I probably did some tests with vcpkg Vulkan SDK but I only started using it with LLVM's libc++ intensively since around Christmas, which is for about 2 months.

Meanwhile on my macOS everything seems in order (I have used it for about 2 years daily):

At least there's C_Cpp.intelliSenseCachePath to work with

I can confirm there is a bug here. We'll get this fixed very soon.
