EXHAUSTIVE BUG INVESTIGATION SUMMARY
ClaudeKit Blender MCP Codebase
Investigation Date: 2025-11-30
================================================================================
INVESTIGATION SCOPE
- Files analyzed: 10 utility modules + index.ts + server.ts
- Total lines of code reviewed: ~3500 LOC
- Timeframe: Runtime, type safety, memory, race conditions, resource cleanup
KEY STATISTICS
- Total bugs identified: 18
- Critical severity: 2
- High severity: 5
- Medium severity: 7
- Low severity: 4
CRITICAL ISSUES REQUIRING IMMEDIATE ATTENTION
1. RACE_CONDITION_001 (connection-pool.ts)
- Connection pool acquire/release race condition
- Multiple threads can acquire same socket simultaneously
- Impact: Socket corruption, undefined behavior, data loss
2. RUNTIME_001 (index.ts)
- Unhandled promise rejection in periodic health check
- Process crashes on health check failure
- Impact: Service unavailability, no graceful degradation
HIGH-PRIORITY FINDINGS
- Socket event listener accumulation (memory leak)
- Health check connections left open (resource leak)
- Type assertions without validation (crashes on malformed data)
- RateLimiter interval orphaned on shutdown (resource leak)
- Pending request queue race condition (dropped requests)
DELIVERABLE
Research report saved to:
/Users/leo/Documents/claudekit-blender-mcp/plans/251130-2140-exhaustive-bug-investigation/research/researcher-01-runtime-types-memory.md
Contains:
- 18 detailed bug descriptions
- Root cause analysis for each
- Code examples showing the issue
- Severity assessment
- Proposed fixes with code samples
- Summary table with categorization
- Implementation recommendations
NEXT STEPS
1. Review bug descriptions for accuracy with development team
2. Create tickets for each bug with severity labels
3. Implement fixes following proposed solutions
4. Add unit tests to prevent regression
5. Conduct load testing to verify race condition fixes
