Exploring SARIF output

[reactive-firewall]

Should consider migrating to SARIF output for our custom checks.
For example SARIF can be generated from python like so:

from sarif import *

# Create a new SARIF file
sarif_file = SarifFile()

# Add a run to the SARIF file
run = Run()
sarif_file.runs.append(run)

# Set the tool information for the run
tool = Tool()
tool.driver = ToolComponent("My Security Tool")
run.tool = tool

# Add an analysis target to the run
analysis_target = AnalysisTarget()
analysis_target.uri = Uri("example.c")
run.analysisTarget = analysis_target

# Add a result to the run
result = Result()
result.ruleId = "SECURITY-1001"
result.level = "error"
result.message = Message("Potential security vulnerability: SQL injection")

# Add a location to the result
location = Location()
location.physicalLocation = PhysicalLocation(
    artifactLocation=ArtifactLocation(uri=Uri("example.c"), index=1),
    region=Region(startLine=10, startColumn=15, endLine=10, endColumn=30)
)
result.locations.append(location)

run.results.append(result)

# Serialize the SARIF file to JSON
sarif_json = sarif_file.to_json()

# Write the SARIF JSON to a file
with open("output.sarif", "w") as f:
    f.write(sarif_json)

@coderabbitai, Please explore how I could use the output SARIF file to upload the results to github's codeQL dashboard. Assume the SARIF file is already generated and named "output.sarif" for this.

Tip

For best results, initiate chat on the files or code changes.

@reactive-firewall, to upload your generated SARIF file output.sarif to GitHub's CodeQL dashboard, you can utilize a GitHub Actions workflow. Here's how you can set this up:

1. Create a new workflow file in your repository under .github/workflows/upload-sarif.yml.

2. Add the following content to the workflow file:

   name: Upload SARIF to Code Scanning
   
   on:
     push:
       branches: [main]
     workflow_dispatch:
   
   jobs:
     upload-sarif:
       runs-on: ubuntu-latest
       steps:
         - name: Checkout repository
           uses: actions/checkout@v3
   
         - name: Upload SARIF file to Code Scanning
           uses: github/codeql-action/upload-sarif@v2
           with:
             sarif_file: output.sarif

   Explanation:

   • Triggers (on): The workflow triggers on pushes to the main branch and can also be manually triggered via the "Run workflow" button in the Actions tab (workflow_dispatch).

   • Jobs:

     • upload-sarif: Defines the job that runs on ubuntu-latest.
       • Checkout the code: Uses actions/checkout@v3 to ensure the SARIF file is accessible.
       • Upload SARIF: Utilizes github/codeql-action/upload-sarif@v2 to upload the output.sarif file to the Code Scanning dashboard.

3. Ensure the SARIF file is available during the workflow execution. If output.sarif is generated by your code, you might need to include the step that creates it before the upload step.

   - name: Generate SARIF file
     run: |
       python3 your_script_that_generates_sarif.py

4. Commit and push the workflow file to your repository.

Once this workflow runs, GitHub will process the SARIF file, and any findings will appear in the "Security" tab under "Code scanning alerts."

Note: If you have multiple SARIF files or need to upload from a different location, you can adjust the sarif_file path accordingly or use wildcards like **/*.sarif.

Let me know if you need further assistance or have any questions!

Tip

For best results, initiate chat on the files or code changes.

@reactive-firewall,

To ensure that your code generates a valid SARIF file compatible with GitHub's code scanning, you can consider the following improvements:

1. Utilize a SARIF Library:

   Instead of manually constructing the SARIF JSON structure, you can leverage existing SARIF libraries like sarif-om to ensure compliance with the SARIF specifications and reduce potential errors.

   Here's how you can modify your code to properly use the sarif-om module:

   import argparse
   import subprocess
   import json
   import sarif_om as sarif
   
   class ShellCheckCLI:
       def __init__(self, shell, severity, files):
           self.shell = shell
           self.severity = severity
           self.files = files
   
       def run_shellcheck(self):
           """Run shellcheck with the specified arguments and return the JSON output."""
           command = ['shellcheck', f'--shell={self.shell}', f'--severity={self.severity}', '--format=json1'] + self.files
           try:
               result = subprocess.run(command, capture_output=True, text=True, check=True)
               return json.loads(result.stdout)
           except subprocess.CalledProcessError as e:
               print(f"Error running shellcheck: {e}")
               return []
   
       def convert_to_sarif(self, shellcheck_results):
           """Convert shellcheck JSON results to SARIF format using sarif-om."""
           # Initialize the SARIF log
           sarif_log = sarif.SarifLog(
               version="2.1.0",
               runs=[
                   sarif.Run(
                       tool=sarif.Tool(
                           driver=sarif.ToolComponent(
                               name="ShellCheck",

               ]
           )
   
           run = sarif_log.runs[0]
           driver = run.tool.driver

                   ruleId=code,
                   message=sarif.Message(
                       text=entry.get('message', '')
                   ),
                   locations=[
                       sarif.Location(
                           physicalLocation=sarif.PhysicalLocation(

                                   startLine=entry.get('line', 0),
                                   startColumn=entry.get('column', 0)

           return sarif_log
   
       def write_sarif(self, sarif_log):

       cli_tool.write_sarif(sarif_log)
   
   if __name__ == "__main__":
       main()

   Key Improvements:

   • Use of sarif_om Library: This ensures that the SARIF file adheres strictly to the SARIF 2.1.0 specification, which GitHub requires.
   • Automatic Schema Compliance: By using the library's classes and methods, you minimize the risk of structural errors in the SARIF file.
   • Dynamic Rule Handling: The code creates rule entries dynamically, ensuring that all unique ShellCheck codes are properly documented.

2. Enhance Code Quality:

   • Error Handling:
     • Provide more informative error messages.
     • Handle potential exceptions when accessing dictionary keys using entry.get('key', default) to avoid KeyError.
   • Logging:
     • Consider integrating the logging module for debug output instead of printing directly to stdout.
   • Code Organization:
     • Break down larger methods into smaller, testable units.
     • Add type hints for better code readability and maintainability.
   • Documentation:
     • Expand docstrings to include parameter descriptions and return types.
     • Provide usage examples in the docstrings or a README file.

3. Ensure Correct File Paths:

   • Relative Paths: Ensure that the uri in artifactLocation is relative to the repository root. This is crucial for GitHub to correctly map the results to the source files.
   • URI Encoding: Use proper URI encoding for file paths to handle spaces and special characters.

4. Make Output File Configurable:

   • Allow users to specify the output SARIF file name via a command-line argument.

     parser.add_argument('--output', default='shellcheck.sarif', help='Specify the output SARIF file name.')

     Update the write_sarif method to use args.output.

5. Add a Requirements File:

   • Include a requirements.txt with the necessary dependencies:

     sarif-om>=1.0.4
     

6. Example Usage in CI/CD:

   • Provide guidance on integrating this script into a CI workflow, ensuring that the SARIF file is generated and uploaded to GitHub's code scanning.

   • GitHub Actions Workflow Example:

     name: ShellCheck SARIF Analysis
     
     on:
       push:
         branches: [main]
       pull_request:
         branches: [main]
       workflow_dispatch:
     
     jobs:
       shellcheck-sarif:
         runs-on: ubuntu-latest
         steps:
           - name: Checkout repository
             uses: actions/checkout@v3
     
           - name: Set up Python
             uses: actions/setup-python@v4
             with:
               python-version: '3.x'
     
           - name: Install dependencies
             run: |
               pip install -r requirements.txt
     
           - name: Run ShellCheck and Generate SARIF
             run: |
               python your_script.py --shell=bash --severity=style scripts/*.sh --output shellcheck.sarif
     
           - name: Upload SARIF file to GitHub Code Scanning
             uses: github/codeql-action/upload-sarif@v2
             with:
               sarif_file: shellcheck.sarif

Additional Considerations:

• Cross-Platform Compatibility:
  • Ensure the script works on different operating systems by handling path separators and shell differences.
• Testing:
  • Write unit tests for your methods, especially the SARIF conversion logic, to ensure accuracy.
• Performance Optimization:
  • If dealing with large codebases, consider optimizing the ShellCheck invocation and SARIF generation for efficiency.

By incorporating these improvements, your script will generate a valid SARIF file suitable for GitHub's code scanning dashboard, leveraging the robustness of an existing SARIF library and enhancing overall code quality.

Tip

For best results, initiate chat on the files or code changes.

@reactive-firewall,

I've reviewed your code for generating a SARIF file from ShellCheck results. To ensure the resulting SARIF file is valid for use with GitHub, here are some suggestions to improve the code:

---

1. Use an Official SARIF Library

Instead of manually constructing the SARIF JSON structure, consider using an official SARIF library like sarif-om. This ensures compliance with the SARIF schema and reduces the risk of formatting errors.

Install the sarif-om library:

pip install sarif-om

Update your code to utilize sarif-om:

import argparse
import subprocess
import json
import os
from sarif_om import SarifLog, Run, Tool, ToolComponent, ReportingDescriptor, Result, Message, PhysicalLocation, ArtifactLocation, Region

class ShellCheckCLI:
    def __init__(self, shell, severity, files):
        self.shell = shell
        self.severity = severity
        self.files = files

    def run_shellcheck(self):
        """Run ShellCheck with the specified arguments and return the JSON output."""
        command = ['shellcheck', f'--shell={self.shell}', f'--severity={self.severity}', '--format=json1'] + self.files
        try:
            result = subprocess.run(command, capture_output=True, text=True, check=True)
            return json.loads(result.stdout)
        except subprocess.CalledProcessError as e:
            print(f"Error running ShellCheck: {e.stderr}")
            return []
        except FileNotFoundError:
            print("ShellCheck is not installed or not found in PATH.")
            return []

    def convert_to_sarif(self, shellcheck_results):
        """Convert ShellCheck JSON results to SARIF format using sarif-om."""
        # Initialize the SARIF log
        sarif_log = SarifLog(
            version="2.1.0",
            runs=[]
        )

        # Create the tool component
        tool = Tool(
            driver=ToolComponent(
                name="ShellCheck",
                version="0.7.2",  # Update to your ShellCheck version
                informationUri="https://www.shellcheck.net/",
                rules=[]
            )
        )

        # Map to store rules
        rule_map = {}

        # Create results list
        results = []

        for entry in shellcheck_results:
            code = str(entry['code'])
            if code not in rule_map:
                # Define a new rule
                rule = ReportingDescriptor(
                    id=code,
                    shortDescription=Message(text=entry.get('message', '')),
                    helpUri=f"https://github.com/koalaman/shellcheck/wiki/SC{code}"
                )
                rule_map[code] = rule
                tool.driver.rules.append(rule)

            # Define the result
            result = Result(
                ruleId=code,
                message=Message(text=entry.get('message', '')),
                locations=[
                    {
                        "physicalLocation": PhysicalLocation(
                            artifactLocation=ArtifactLocation(
                                uri=os.path.relpath(entry['file'])
                            ),
                            region=Region(
                                startLine=entry['line'],
                                startColumn=entry['column']
                            )
                        )
                    }
                ]
            )
            results.append(result)

        # Assemble the run
        run = Run(
            tool=tool,
            results=results
        )

        sarif_log.runs.append(run)
        return sarif_log

    def write_sarif(self, sarif_log):
        """Write the SARIF log to a file."""
        with open("shellcheck.sarif", "w") as sarif_file:
            json.dump(sarif_log.to_dict(), sarif_file, indent=2)

def main():
    parser = argparse.ArgumentParser(description="Run ShellCheck and output results in SARIF format.")
    parser.add_argument('--shell', choices=['bash', 'sh', 'dash', 'ksh', 'busybox'], default='bash', help='Specify the shell type.')
    parser.add_argument('--severity', choices=['error', 'warning', 'info', 'style'], default='style', help='Specify the severity level.')
    parser.add_argument('FILES', nargs='+', help='One or more files or glob patterns to check.')

    args = parser.parse_args()

    cli_tool = ShellCheckCLI(args.shell, args.severity, args.FILES)
    shellcheck_results = cli_tool.run_shellcheck()
    sarif_log = cli_tool.convert_to_sarif(shellcheck_results)
    cli_tool.write_sarif(sarif_log)

if __name__ == "__main__":
    main()

Benefits of using sarif-om:

• Schema Compliance: Automatically adheres to the SARIF 2.1.0 specification required by GitHub.
• Maintainability: Easier to read and maintain compared to manual JSON construction.
• Error Reduction: Minimizes potential for structural errors in the SARIF file.

---

2. Additional Improvements

• Enhanced Error Handling:

  • Use the logging module for better control over logging levels and outputs.
  • Handle exceptions like FileNotFoundError when shellcheck is not installed.

• Command-Line Argument Validation:

  • Check if the provided files exist before passing them to ShellCheck.
  • Provide user-friendly messages if files are missing.

• Code Organization:

  • Separate concerns by adding helper methods or classes if the codebase grows.
  • Use more descriptive variable names where applicable.

• Type Hints and Documentation:

  • Add type hints to function signatures for better clarity and tooling support.
  • Expand docstrings to provide more detailed explanations of methods.

• Use of F-Strings:

  • Ensure consistent use of f-strings for string formatting for readability.

---

3. Example with Enhanced Error Handling and Logging

import argparse
import subprocess
import json
import os
import logging
from sarif_om import SarifLog, Run, Tool, ToolComponent, ReportingDescriptor, Result, Message, PhysicalLocation, ArtifactLocation, Region

logging.basicConfig(level=logging.INFO)

class ShellCheckCLI:
    def __init__(self, shell: str, severity: str, files: list):
        self.shell = shell
        self.severity = severity
        self.files = files

    def run_shellcheck(self) -> list:
        """Run ShellCheck with the specified arguments and return the JSON output."""
        command = ['shellcheck', f'--shell={self.shell}', f'--severity={self.severity}', '--format=json1'] + self.files
        try:
            logging.info(f"Running command: {' '.join(command)}")
            result = subprocess.run(command, capture_output=True, text=True, check=True)
            return json.loads(result.stdout)
        except subprocess.CalledProcessError as e:
            logging.error(f"ShellCheck error: {e.stderr}")
            return []
        except FileNotFoundError:
            logging.error("ShellCheck is not installed or not found in PATH.")
            return []

    # ... (rest of the code remains the same)

---

4. Verify SARIF File with GitHub

• Testing: Before integrating into your CI/CD pipeline, manually upload the generated shellcheck.sarif file to your repository's code scanning alerts to verify compatibility.
• Continuous Integration: Incorporate this script into your CI workflow to automatically generate and upload SARIF files on code changes.

---

5. Ensure Relative Paths in artifactLocation

• Use os.path.relpath(entry['file']) to provide paths relative to the repository root, ensuring GitHub correctly maps the results to the source files.
