[duplicate-code] Duplicate Code Analysis Report - Server Logger Functions

[github-actions]

🔍 Duplicate Code Analysis Report

Analysis of commit 1041860 (Sanitize environment variables in Docker args logging)

Summary

This analysis identified 1 significant duplication pattern in the Go codebase that exceeds the reporting threshold (>10 lines of duplicated code). The duplication exists in the logger package's server-specific logging functions.

Detected Patterns

This analysis found 1 significant duplication pattern:

1. Duplicate Server Logger Functions - Severity: High - See sub-issue [duplicate-code] Duplicate Code Pattern: Server Logger Functions (LogWithServer) #912

Overall Impact

• Total Duplicated Lines: ~48 lines (4 nearly identical functions)
• Affected Files: 1 file (internal/logger/server_file_logger.go)
• Maintainability Risk: Medium - Changes to logging logic require updates in 4 places
• Refactoring Priority: High - Simple refactoring with high value

Analysis Context

Scope:

• Analyzed 69 non-test Go files changed in latest commit
• Focused on internal/ packages (logger, config, cmd, server, guard, launcher)
• Excluded test files, workflow files, and agent configurations

Detection Method:
Serena semantic code analysis with:

• Symbol overview analysis for structure understanding
• Pattern search for similar code blocks
• Manual inspection of flagged patterns

Note on Intentional Patterns:
The codebase contains several documented patterns that appear duplicated but are intentional design decisions:

• Logger initialization patterns (documented in internal/logger/common.go)
• Logger Close() methods (documented as standard Go idiom)
• Config validation separated by domain (by design for modularity)

These patterns were excluded from this report as they represent conscious architectural choices.

Next Steps

1. Review the sub-issue for detailed analysis of the duplication pattern
2. Assess refactoring feasibility and impact
3. Create implementation plan if refactoring is approved
4. Ensure any changes maintain thread safety and error handling behavior
