Exclusions aren't applied to the first directory found for each browse.path entry

Environment

• OS and Version: Mac OS
• VS Code Version: 1.73.1
• C/C++ Extension Version: Microsoft extensions (C/C++ and C/C++ extension back)
• Other extensions you installed (and if the issue persists after disabling them): CodeLLDB
• If using SSH remote, specify OS of remote machine: No
• A clear and concise description of what the bug is, including information about the workspace (i.e. is the workspace a single project or multiple projects, size of the project, etc).

Bug Summary and Steps to Reproduce

Bug Summary:
I created a workspace with many folder. Inside each folder there exists many files.

I build this settings.json:

{
"files.associations": {
"memory": "c",
"variant": "c"
},
"search.exclude": {
"/firmware": true,
"/cellular" : true,
"/common":true,
"/embedded_headers" : true,
"/output" : true,
"/platform_sw":true,
},
"files.exclude": {
"/*.unt": true,
"/*.c":false,
},
"C_Cpp.exclusionPolicy": "checkFilesAndFolders",
"C_Cpp.intelliSenseEngine": "Default",
}

the "search.exclude" entry contains all folder in the project.

Steps to reproduce:
see above.
I also reset the IntelliSense DB.

Expected behavior

When I reset IntelliSense DB, I still see its progress as multiple files. I expected no files to be included since all folders where added in the search exclude entry.

I expected that IntelliSense wouldn't find any function declaration, when I right click on a function and press "go to definition"

Code sample and Logs

c_cpp_properties.json doesn't exist in my project.

Our extension doesn't look at the search.exclude feature, because we consider that setting to only apply to VS Code's search. You should set C_Cpp.files.exclude instead.

Thanks for the reply.
I added the entry to the settings.json

  "C_Cpp.files.exclude": {

        "**/firmware_pmu": true,
        "**/cellular" : true,
        "**/tools": true,
        "**/common":true,
        "**/embedded_headers" : true,
        "**/firmware_bb":true,
        "**/output" : true,
        "**/platform":true,
        "**/vinyl":true,        
        "**/.vscode": true,
        "**/.vs": true
  },
  "C_Cpp.codeAnalysis.exclude": {
        "**/firmware_pmu": true,
        "**/cellular" : true,
        "**/tools": true,
        "**/common":true,
        "**/embedded_headers" : true,
        "**/firmware_bb":true,
        "**/output" : true,
        "**/platform":true,
        "**/vinyl":true,        
        "**/.vscode": true,
        "**/.vs": true
  },

when I reset the intellisense database, I still see it discovering all files in the project. (all folders in the project are excluded for testing the extension)

[sean-mcmanus]

Can you set C_Cpp.loggingLevel to "Debug" and look at the "C/C++" logging to see which folder are being processed, e.g.

Discovering files...
  Processing folder (recursive): 

[akhodeir]

Thanks for the hints.

I enabled the debug mode. here is the output:

`
Processing folder (recursive): /Library/Developer/CommandLineTools/SDKs/******
Processing folder (recursive): /Library/Developer/CommandLineTools/SDKs/******
Discovering files: 41383 file(s) processed
0 file(s) removed from database
Done discovering files.
Populating include completion cache.
Parsing remaining files...
Parsing: 0 files(s) processed
Done parsing remaining files.

`
Note: complete pathes are removed and "******" are used instead.

I tried to disable them via "C_Cpp.files.exclude" and "C_Cpp.codeAnalysis.exclude" ---> "/Library/Developer/CommandLineTools/SDKs/*":true
but they are still processed

It appears to be a bug. The files.exclude is not applied to the root folder if it's in the browse.path. You can work around this bug via setting "C_Cpp.exclusionPolicy": "checkFilesAndFolders" (that setting is not recommended after this bug is fixed though).

[sean-mcmanus]

But if you have "C_Cpp.exclusionPolicy": "checkFilesAndFolders" set already, then I'm not sure why the exclusion wouldn't be working (it works for me). You could potentially set "C_Cpp.loggingLevel": "8", temporarily to get more exclusion info.

The fix is available with 1.14.0 (pre-release): https://github.com/microsoft/vscode-cpptools/releases/tag/v1.14.0
