Not able to import llvm-cov report

SonarQube Server / Community Build

Hi
Using clang and followed the SonarQube directions for cfamily.llvm-cov

I’m not getting the codecoverage report in SonarQube dashboard.

I’m using Code Analyzer for C, C++, Objective-C 6.8.0 (build 16475)installed

Hello @Eric_Dunn,

Try to use forward slash instead of backslash.
Try this instead sonar.cfamily.llvm-cov.reportPath=bld_clang_ninja_cov/coveragereport.txt
Same for sonar.sources.

Can you also upload the file coveragereport.txt. Let me know if you prefer to share it privately.

Thanks,

Okay… magic feather is…
Make sure coveragereport is in Ascii

Get-Content core\bld_clang_ninja_cov\coveragereport.txt | Set-Content -Encoding Ascii core\bld_clang_ninja_cov\coveragereport_Ascii.txt

Solved

Using Jenkins. Windows10 Node.
C++ code using clang.exe

Everything works except publishing the code coverage reports… sigh

Let me share file privately

Strange… “gedit” is only text editor that sees bad chars.

The file you opened has some invalid characters. If you continue editing this file you could corrupt this document.
You can also choose another character encoding and try again.

I also found the following:
https://jar-download.com/artifacts/commons-io/commons-io/2.5/source-code/org/apache/commons/io/FilenameUtils.java

private static void failIfNullBytePresent(String path) {
        int len = path.length();
        for (int i = 0; i < len; i++) {
            if (path.charAt(i) == 0) {
                throw new IllegalArgumentException("Null byte present in file/path name. There are no " +
                        "known legitimate use cases for such data, but several injection attacks may use it");
            }
        }
    }
