paths-ignore and monorepo 'excluding' noisy

[indy-singh]

We are using this:-

    - uses: github/codeql-action/init@v4
      with:
        languages: csharp
        build-mode: none
        debug: true
        config: |
          paths: 
            - '/src/${{needs.pr-plan.outputs.app_changed}}/**'
          paths-ignore:
            - '/src/${{needs.pr-plan.outputs.app_changed}}/test/**'
      env:
        GH_TOKEN: ${{ secrets.GITHUB_TOKEN }}

Inside a monorepo (1.4 million LOC across 19k files) and we find that the output from the action is dominated by lines like:-

It's about 100,000 lines of "Excluding" and it generates a raw log file of about 80-100MB. Which is a lot to scroll through when you are debugging CodeQL issues.

codeql/csharp/extractor/Semmle.Extraction.CSharp.DependencyFetching/FilePathFilter.cs

Line 94 in 004dfbd

logger.LogInfo($"Excluding '{f.FileInfo.FullName}'");

Is there a chance we could get it as a artefact on the upload? And not write to Actions output?

Cheers,
Indy

That line should arguably use LogDebug instead of LogInfo.

Thanks for bringing this to our attention, a fix has now been merged, so closing.
