codeql

To configure CodeQL code scanning in GitHub Actions, you must grant `security-events: write` permissions to your workflow token and use the `github/codeql-action/init@v4` and `analyze@v4` actions to initialize and analyze your code, ultimately uploading the generated SARIF file.

CodeQL autobuild failures for compiled languages often stem from missing build tools or incorrect environment setup. You can resolve this by selecting the appropriate build-mode (none, autobuild, or manual) in your workflow configuration and troubleshooting resource-limitation issues like runner disk exhaustion.

Yes, you can run CodeQL SAST analysis locally using the CodeQL CLI. You need to manually create a CodeQL database for your target language, execute the analysis queries, and then review or upload the resulting SARIF security findings output.

The best way to run CodeQL security scanning for mixed-language repositories is to configure a language matrix in your GitHub Actions workflow. This allows you to select the appropriate build-mode for each language component and upload standardized SARIF results individually.

Yes, generating and uploading SARIF security findings requires the `security-events: write` permission in your GitHub Actions workflow configuration. Without this explicit permission, the CodeQL analysis action cannot successfully upload the security scanning results to your repository.

CodeQL database build and analysis works by extracting a relational representation of your codebase, allowing queries to identify security issues. When troubleshooting workflow failures, you can manually adjust the build-mode or use the CLI to isolate resource-limitation and autobuild issues.
