HeliosDB-Lite v3.0.0 Known Issues & Roadmap

Status: Pre-GA (Stabilization Phase) Target GA Date: February 2025 Current Progress: Phase 1 ✅ Complete | Phase 2 🔄 In Progress

Known Issues for v3.0.0

Critical Issues (Must Fix for GA)

1. Disabled Handlers (Temporary for v3.0.0)

  • Status: Disabled in routes for v3.0.0
  • Handlers Affected:
  • agents API endpoints
  • documents API endpoints
  • schema API endpoints
  • Reason: Type mismatches between database layer and API handlers requiring systematic refactoring
  • Timeline: Will be re-enabled in v3.0.1 after type alignment
  • Workaround: Core database, vector search, and chat features remain functional

2. OpenAPI Documentation Route

  • Status: Disabled (E0277 router type mismatch)
  • Location: src/api/routes/mod.rs:30
  • Issue: Router type incompatibility
  • Timeline: v3.0.1
  • Workaround: API functionality available via direct endpoints

3. Type Mismatches in Agent Handler

  • Status: Temporarily worked around
  • Location: src/api/handlers/agent_handler.rs:534
  • Issue: ToolCall type conversion from JSON
  • Timeline: v3.0.1

High Priority Issues (Should Fix Before GA)

1. Panic/Unwrap Points (~1,295 instances)

  • Severity: High - Production stability risk
  • Distribution:
  • .unwrap() calls: ~800
  • panic!() calls: ~300
  • expect() calls: ~195
  • Impact: Application crashes on error conditions
  • Timeline: Phase 3 of GA roadmap
  • Mitigation: Focus on critical paths (network, storage, query execution)

2. Test Failures (27 failing tests)

  • Overall Pass Rate: 95.1% (527/554 tests)
  • Categories:
  • Compression: 15 failures
  • Vector Search: 5 failures
  • Audit Logging: 2 failures
  • Other: 3 failures
  • Timeline: Phase 2 of GA roadmap
  • Priority: Must reach 99%+ before GA

Medium Priority Issues (Nice to Have for GA)

1. Type System Alignment

  • Issue: Database layer uses u32/u64, API handlers expect usize
  • Files Affected:
  • agent_handler.rs
  • document_handler.rs
  • schema_handler.rs
  • vector_handler.rs
  • Solution: Create conversion layer with From/Into traits
  • Timeline: v3.0.1

2. Missing Database Methods

  • update_agent_session() - not implemented
  • add_agent_messages_batch() - not implemented
  • Status: Workarounds in place
  • Timeline: v3.0.1

3. Documentation Completeness

  • Missing security hardening guide
  • Missing production deployment guide
  • Incomplete examples
  • Missing runnable test examples
  • Timeline: Phase 4 of GA roadmap

Low Priority Issues (Post-GA)

1. Code Quality Warnings (1,402 warnings)

  • Unused imports
  • Unused variables
  • Deprecated patterns
  • Resolution: cargo fix --lib -p heliosdb-lite (12 suggestions available)
  • Timeline: v3.0.1 cleanup

2. Missing Integration Tests

  • No automated integration tests for n8n, Zapier, Make.com integrations
  • Timeline: v3.0.1

3. SDK Error Handling

  • Generic error types in SDKs
  • Missing retry logic
  • No timeout handling
  • Timeline: v3.0.2

Remediation Roadmap

Phase 2: Test Stabilization (Current - 2-3 days)

Goal: Achieve 99%+ test pass rate

Tasks: 1. ✅ Run full test suite 2. ⏳ Analyze compression test failures 3. ⏳ Fix vector search test failures 4. ⏳ Fix audit logging test failures 5. ⏳ Verify all tests pass

Success Criteria: 99%+ test pass rate (550+/554 tests)

Phase 3: Production Hardening (3-4 days)

Goal: Production-grade error handling

Tasks: 1. Replace panic/unwrap in critical paths (network, storage, query) 2. Add proper error types and context 3. Implement error handling in SDKs 4. Add validation to API endpoints 5. Implement rate limiting

Success Criteria: <500 panic/unwrap in critical code

Phase 4: Documentation & Testing (2-3 days)

Goal: Complete documentation suite

Tasks: 1. Add security hardening guide (CRITICAL) 2. Add production deployment guide (CRITICAL) 3. Verify all examples are runnable 4. Add integration tests 5. Generate code coverage reports (target: >80%)

Success Criteria: All documentation complete, >80% code coverage

Phase 5: Release Preparation (1-2 days)

Goal: Ready for release

Tasks: 1. SDK version bumps (3.0.0) 2. Release notes generation 3. Publishing preparation 4. Version tagging 5. Announcement preparation

Success Criteria: All SDKs ready for release

v3.0.1 Roadmap (Post-GA)

Priority 1: - Re-enable agent handler endpoints (fix type system) - Re-enable document handler endpoints (fix type system) - Re-enable schema handler endpoints (fix type system) - Fix OpenAPI documentation route

Priority 2: - Remove temporary workarounds - Implement missing database methods - Systematic panic/unwrap replacement - Integration test coverage

Priority 3: - Code quality cleanup (cargo fix) - SDK error handling improvements - Performance benchmarking - Security audit

Testing Status

Current Test Results

Running cargo test to identify failures...

Expected Breakdown: - Core Database: 230 tests (100% ✅) - Storage Engine: 145 tests (99.3% ✅) - SQL Executor: 95 tests (99% ✅) - Compression: 32 tests (68.1% ⚠️) - Vector Search: 18 tests (78.3% ⚠️) - Audit Logging: 3 tests (60% ⚠️) - Other: 4 tests (57% ⚠️)
