CRASH: trading_engine (SIGABRT)

Fatal Error:

free(): double free detected in tcache 2
signal: 6, SIGABRT: process abort signal

Context:

  • Occurs during lock-free atomic operations tests
  • Memory corruption in concurrent data structures
  • Indicates critical memory safety issue

Status: Tests aborted, unknown pass/fail count

⏸️ BLOCKED: Services (5 crates)

The following services timed out during compilation/testing:

  1. api_gateway
  2. trading_service
  3. backtesting_service
  4. ml_training_service
  5. e2e_ensemble_integration

Reason: Build lock contention + long compilation times

Critical Blockers

1. Data Crate - Compilation Failures (PRIORITY 1)

Issue: Missing fields in MarketDataEvent struct initialization Fix Required:

// Current (BROKEN):
let event = MarketDataEvent {
    symbol: symbol.clone(),
    price: close,
    volume: volume as f64,
    timestamp: timestamp_nanos,
    event_type: EventType::Trade,
    // MISSING: high, low, open
};

// Fixed:
let event = MarketDataEvent {
    symbol: symbol.clone(),
    price: close,
    volume: volume as f64,
    timestamp: timestamp_nanos,
    event_type: EventType::Trade,
    high: close,  // Add with placeholder
    low: close,   // Add with placeholder
    open: close,  // Add with placeholder
};

Files to Fix:

  • data/tests/parquet_persistence_tests.rs (5 instances)
  • data/examples/convert_dbn_to_parquet.rs

2. ML Crate - 8 Test Failures (PRIORITY 2)

Categories:

  • Model creation/initialization: 2 failures
  • Feature extraction: 1 failure
  • Training loop: 5 failures

Estimated Fix Time: 30-60 minutes per test = 4-8 hours

3. Trading Engine - Memory Corruption (PRIORITY 1 - CRITICAL)

Issue: Double-free in atomic operations causing SIGABRT Risk Level: CRITICAL - Production blocking Impact: Crashes entire test suite, indicates memory unsafety Investigation Required: Lock-free queue implementation audit


Comparison to Wave 5 Baseline

Metric Wave 5 Wave 6 Delta
Total Tests 1,223 1,229+ +6
Passed 1,203 1,221 +18
Failed 20 8 -12
Pass Rate 98.36% 99.34% +0.98%

Progress: Wave 6 improved pass rate by ~1% despite adding more tests


100% Pass Rate Goal Assessment

Goal Achieved: NO

Remaining Work:

  1. Fix data crate compilation (BLOCKER - 0 tests run)

    • Estimated: 15-30 minutes
  2. Fix 8 ML test failures (NEAR-GOAL - 98.9% pass rate)

    • Estimated: 4-8 hours
  3. Debug trading_engine crash (CRITICAL)

    • Estimated: 4-16 hours (memory corruption bugs are complex)
  4. Complete service tests (BLOCKED)

    • api_gateway: ~80 tests expected
    • trading_service: ~50 tests expected
    • backtesting_service: ~12 tests expected
    • ml_training_service: ~30 tests expected
    • e2e: ~22 tests expected
    • Total: ~194 tests untested

Realistic Pass Rate Projection:

  • Best case (all services pass): 99.5-100%
  • Likely case (some service failures): 98.5-99.5%
  • Worst case (trading_engine unfixable): 95-98%

Recommendations

Immediate Actions (Next 4 Hours)

  1. Fix data crate compilation errors (30 min)

    • Add missing OHLC fields to test fixtures
    • Verify all parquet tests compile and run
  2. Re-run complete test suite (60 min)

    • Clear build locks: killall cargo
    • Run overnight: cargo test --workspace --release -- --test-threads=1
  3. Debug trading_engine crash (2+ hours)

    • Run under Valgrind: valgrind --leak-check=full target/release/deps/trading_engine-*
    • Isolate lock-free queue double-free
    • Consider disabling test until fixed

Short-Term (Next 24 Hours)

  1. Fix 8 ML test failures

    • Prioritize training loop tests (production critical)
    • May require MAMBA-2 model fixes from prior agents
  2. Complete service test execution

    • Run services sequentially with 10-minute timeouts
    • Document any new failures

Long-Term (Next Week)

  1. Implement regression prevention

    • Add pre-commit hook: cargo test --workspace
    • CI/CD gate: 99% pass rate minimum
  2. Memory safety audit

    • Full Valgrind run on trading_engine
    • Consider memory sanitizers (ASAN/MSAN)

Technical Notes

Build System Issues

  • Cargo build lock contention caused timeouts
  • Solution: Run tests with --test-threads=1 or sequentially

Test Environment

  • Platform: Linux 6.14.0-33-generic
  • Rust: 1.82+ (edition 2021)
  • CUDA: RTX 3050 Ti (not used in unit tests)
  • RAM: Sufficient (no OOM observed)

Warnings (Non-Blocking)

  • data crate: 60+ unused dependency warnings
  • ml crate: 15 unused imports, 10 unused variables
  • Impact: None (warnings don't affect functionality)

Conclusion

Wave 6 Test Status: 🟡 PARTIAL SUCCESS

Achievements: 99.34% pass rate on executed tests (+0.98% vs Wave 5) Common, storage crates: 100% pass (397 tests) ML crate: 98.9% pass (824/832 tests) Reduced failures from 20 → 8 (60% improvement)

Critical Blockers: Data crate: Compilation failure (BLOCKER) Trading engine: Memory corruption crash (CRITICAL) Services: Not tested (194 tests remaining)

100% Goal Status: Not achieved, but significant progress made

Next Steps: Fix data compilation → Re-run full suite → Debug crashes → Fix ML failures

Estimated Time to 100%: 12-24 hours of focused debugging
