Bug: Severity Is Not Mapped Properly When Issue Severity Does Not Match IssueType Severity

by ADMIN 91 views

Introduction

When using the Resharper CLT inspectcode command to generate a report, the severity of an issue may not be mapped properly if the issue severity does not match the issue type severity. This can occur when the severity level of the inspection is customized in .editorconfig or similar, and this behavior is documented in the InspectCode documentation.

The Issue

The issue arises when the Resharper CLT inspectcode command outputs a Severity attribute in an Issue element that differs from the associated IssueType's Severity attribute. This can be seen in the following example XML output:

<?xml version="1.0" encoding="utf-8"?>
<!-- Generated by JetBrains Inspect Code 2025.1.2 -->
<Report ToolsVersion="251.0.20250507.95416">
    <Information>
        <Solution>my-solution.sln</Solution>
        <InspectionScope>
            <Element>Solution</Element>
        </InspectionScope>
    </Information>
    <IssueTypes>
        <IssueType Id="InconsistentNaming" 
                   Category="Constraints Violations" 
                   CategoryId="ConstraintViolation"
                   Description="Inconsistent Naming" 
                   Severity="WARNING"
                   WikiUrl="https://www.jetbrains.com/help/resharper/InconsistentNaming.html"/>
    </IssueTypes>
    <Issues>
        <Project Name="my-solution">
            <Issue TypeId="InconsistentNaming" 
                   Severity="ERROR"
                   File="my-solution\Program.cs"
                   Offset="69-79" 
                   Line="3"
                   Message="Name 'snake_case' does not match rule 'Local variables'. Suggested name is 'snakeCase'."/>
        </Project>
    </Issues>
</Report>

In this example, the IssueType's Severity is set to WARNING, but the Issue's Severity is set to ERROR. This discrepancy is due to the customized severity level in the .editorconfig file:

[*]
resharper_inconsistent_naming_highlighting = error

The Impact

When the resharper-to-codeclimate command is run on the XML above, the generated CodeClimate file does not accurately reflect the Issue's severity. The resulting JSON output is:

[
  {
    "check_name": "InconsistentNaming",
    "description": "Name \u0027snake_case\u0027 does not match rule \u0027Local variables\u0027. Suggested name is \u0027snakeCase\u0027.",
    "fingerprint": "dcd4fddb3bbdcb41b8f38e9f31baf359",
    "severity": "major",
    "location": {
      "path": "my-solution/Program.cs",
      "lines": {
        "begin": 3
      }
    }
  }
]

As can be seen, the severity is incorrectly set to MAJOR (Resharper WARNING) instead of CRITICAL (Resharper ERROR).

The Solution

To resolve this issue, can modify the resharper-to-codeclimate command to grab the Severity from the Issue by default, and fall back to the IssueType's Severity if the Issue itself does not have the attribute. This will ensure that the generated CodeClimate file accurately reflects the Issue's severity.

Implementation

The modified resharper-to-codeclimate command can be implemented as follows:

import xml.etree.ElementTree as ET

def parse_xml(xml_file):
    tree = ET.parse(xml_file)
    root = tree.getroot()
    issues = []
    for project in root.findall('.//Project'):
        for issue in project.findall('.//Issue'):
            issue_type_id = issue.get('TypeId')
            issue_type = next((it for it in root.findall('.//IssueType') if it.get('Id') == issue_type_id), None)
            if issue_type:
                issue_severity = issue.get('Severity') or issue_type.get('Severity')
                issues.append({
                    'check_name': issue_type.get('Id'),
                    'description': issue.get('Message'),
                    'fingerprint': 'fingerprint',
                    'severity': issue_severity,
                    'location': {
                        'path': issue.get('File'),
                        'lines': {
                            'begin': int(issue.get('Line'))
                        }
                    }
                })
    return issues

def main():
    xml_file = 'inspectcode.xml'
    issues = parse_xml(xml_file)
    print(issues)

if __name__ == '__main__':
    main()

This implementation uses the xml.etree.ElementTree module to parse the XML file and extract the Issue's Severity. If the Issue itself does not have the Severity attribute, it falls back to the IssueType's Severity.

Conclusion

Q: What is the issue with the Resharper CLT inspectcode command?

A: The Resharper CLT inspectcode command outputs a Severity attribute in an Issue element that differs from the associated IssueType's Severity attribute. This can occur when the severity level of the inspection is customized in .editorconfig or similar.

Q: What is the impact of this issue?

A: When the resharper-to-codeclimate command is run on the XML output, the generated CodeClimate file does not accurately reflect the Issue's severity. This can lead to incorrect severity levels being reported in the CodeClimate file.

Q: What is the solution to this issue?

A: To resolve this issue, we can modify the resharper-to-codeclimate command to grab the Severity from the Issue by default, and fall back to the IssueType's Severity if the Issue itself does not have the attribute.

Q: How can I implement this solution?

A: You can implement this solution by modifying the resharper-to-codeclimate command to use the following logic:

  • Grab the Severity from the Issue by default
  • Fall back to the IssueType's Severity if the Issue itself does not have the Severity attribute
