3. Backtesting Service (Port 50052)

Status: 🔴 FAILED - TLS Crypto Provider Panic

✗ Process crashed on startup
✗ Port not listening
✗ Service unavailable

Critical Error:

thread 'main' panicked at rustls-0.23.32/src/crypto/mod.rs:249:14:

Could not automatically determine the process-level CryptoProvider from Rustls crate features.
Call CryptoProvider::install_default() before this point to select a provider manually,
or make sure exactly one of the 'aws-lc-rs' and 'ring' features is enabled.

Root Cause:

• Rustls 0.23.32 requires explicit crypto provider
• Missing CryptoProvider::install_default() call
• Compilation features not properly configured
• Service initialization fails before gRPC server starts

Required Fix:

// Add to services/backtesting_service/src/main.rs
use rustls::crypto::CryptoProvider;

fn main() {
    // Install crypto provider before any TLS operations
    CryptoProvider::install_default(
        rustls::crypto::aws_lc_rs::default_provider()
    ).expect("Failed to install crypto provider");

    // ... rest of initialization
}

Last Successful Log:

[2025-10-03T13:49:50] INFO Starting gRPC server on 0.0.0.0:50052
[2025-10-03T13:49:50] INFO ✅ HTTP/2 optimizations enabled

4. API Gateway (Port 50050)

Status: 🔴 FAILED - Port Conflict

✗ Process not running
✗ Port 50050 not listening
✗ Service unavailable

Critical Error: Port conflict detected

Last Known Logs:

[2025-10-03T13:48:44] INFO Starting Foxhunt API Gateway Service
[2025-10-03T13:48:44] INFO Bind address: 0.0.0.0:50051  ⚠️ CONFLICT!
[2025-10-03T13:48:44] INFO JWT issuer: foxhunt-api-gateway
[2025-10-03T13:48:44] WARN JWT secret loaded from environment variable

Root Cause:

• API Gateway attempting to bind to 0.0.0.0:50051
• Trading Service already bound to port 50051
• Port allocation mismatch in configuration
• Expected: API Gateway on 50050, Trading on 50051

Required Fix:

1. Check .env file for GRPC_PORT configuration
2. Verify API Gateway binary uses correct port
3. Ensure no hardcoded port 50051 in api_gateway code
4. Restart with explicit GRPC_PORT=50050 environment variable

🚨 Critical Blockers

Blocker 1: Backtesting Service - TLS Crypto Provider Panic

Severity: 🔴 CRITICAL Impact: Service completely non-functional Component: services/backtesting_service

Error:

Could not automatically determine the process-level CryptoProvider from Rustls crate features.

Fix Required:

// services/backtesting_service/src/main.rs
use rustls::crypto::CryptoProvider;

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    // CRITICAL: Install crypto provider before any TLS operations
    CryptoProvider::install_default(
        rustls::crypto::aws_lc_rs::default_provider()
    ).expect("Failed to install default crypto provider");

    // Initialize tracing...
    // Rest of main() continues
}

Alternative Fix (if aws-lc-rs not available):

CryptoProvider::install_default(
    rustls::crypto::ring::default_provider()
).expect("Failed to install default crypto provider");

Testing:

# Rebuild with fix
cargo build --release --package backtesting_service

# Start service
GRPC_PORT=50052 ./target/release/backtesting_service serve --dev

# Verify
grpcurl -plaintext localhost:50052 list

---

Blocker 2: API Gateway - Port Conflict with Trading Service

Severity: 🔴 CRITICAL Impact: API Gateway cannot start Component: services/api_gateway

Issue: API Gateway binding to port 50051 (already used by Trading Service)

Expected Port Allocation:

API Gateway:       0.0.0.0:50050
Trading Service:   0.0.0.0:50051
Backtesting:       0.0.0.0:50052
ML Training:       0.0.0.0:50053

Fix Options:

1. Environment Variable (Quickest):

# Check current configuration
grep GRPC_PORT .env

# Set correct port
export GRPC_PORT=50050
./target/release/api_gateway serve --dev

2. Configuration File (Recommended):

# services/api_gateway/config/default.toml
[server]
bind_address = "0.0.0.0:50050"

3. Code Fix (if hardcoded):

// services/api_gateway/src/main.rs
// Search for hardcoded port 50051
let addr = "[::]:50050".parse()?; // Change to 50050

Verification:

# After fix
ps aux | grep api_gateway
netstat -tln | grep 50050

# Test connection
grpcurl -plaintext localhost:50050 list

---

Blocker 3: ML Training Service - Connection Timeout

Severity: 🔴 CRITICAL Impact: Service unresponsive to requests Component: services/ml_training_service

Symptoms:

• Process running (PID 1270680)
• Port listening (50053)
• Accepts connections
• No response to gRPC requests (60+ second timeout)

Possible Causes:

1. Blocking operation in server initialization

   • Deadlock waiting for database/vault
   • Async runtime misconfiguration
   • Channel blocking in orchestrator

2. gRPC reflection not properly registered

   • Reflection service added but not functional
   • Service builder misconfiguration

3. TLS handshake issues

   • mTLS configuration blocking connections
   • Certificate validation timeout

Diagnostic Steps:

# Check if process is actually blocked
strace -p 1270680 2>&1 | head -20

# Check open file descriptors
lsof -p 1270680 | grep -E "(TCP|LISTEN)"

# Test with increased timeout
grpcurl -plaintext -max-time 120 localhost:50053 list

# Test without TLS (if supported)
grpcurl -plaintext -insecure localhost:50053 list

Investigation Required:

// Check services/ml_training_service/src/main.rs
// Look for:
// 1. Blocking calls in async context
// 2. Mutex deadlocks
// 3. Channel recv() without timeout
// 4. Database connection pool exhaustion

Temporary Workaround:

# Restart service with debug logging
pkill ml_training_service
RUST_LOG=debug,ml_training_service=trace \
  GRPC_PORT=50053 \
  ./target/release/ml_training_service serve --dev > /tmp/ml_debug.log 2>&1 &

# Monitor logs for blocking operation
tail -f /tmp/ml_debug.log

Phase 2: Integration Testing (After Phase 1 Complete)

Test 1: gRPC Health Checks

# Test all services
for port in 50050 50051 50052 50053; do
    echo "Testing port $port:"
    grpcurl -plaintext -max-time 5 localhost:$port list
done

Test 2: API Gateway Proxying

# Generate test JWT
TOKEN=$(./scripts/generate_test_jwt.sh)

# Test through API Gateway
grpcurl -plaintext \
  -H "authorization: Bearer $TOKEN" \
  localhost:50050 \
  foxhunt.ApiGateway/Health

Test 3: Rate Limiting

# Generate 150 requests (limit is 100/s)
for i in {1..150}; do
  grpcurl -plaintext localhost:50050 list &
done
wait

# Check Redis for rate limit counters
docker exec api_gateway_test_redis redis-cli KEYS "ratelimit:*"

Test 4: Inter-Service Communication

# API Gateway → Trading Service
grpcurl -plaintext -H "authorization: Bearer $TOKEN" \
  localhost:50050 foxhunt.ApiGateway/ExecuteTrade \
  -d '{"symbol":"AAPL","quantity":100,"side":"BUY"}'

# Check audit logs in PostgreSQL
psql -h localhost -p 5433 -U postgres -d test \
  -c "SELECT * FROM audit_logs ORDER BY timestamp DESC LIMIT 10;"

🎓 Lessons Learned

1. TLS Configuration Complexity

Issue: Rustls 0.23.32 requires explicit crypto provider installation Impact: Service panics at startup with cryptic error message Solution: Always call CryptoProvider::install_default() before TLS operations Prevention: Add to service template/boilerplate code

2. Port Allocation Management

Issue: API Gateway bound to wrong port (50051 instead of 50050) Impact: Port conflict prevents service startup Solution: Centralize port allocation in documentation and CI/CD validation Prevention: Add port conflict detection to startup scripts

3. gRPC Reflection Importance

Issue: Trading Service doesn't support reflection API Impact: Cannot introspect or test service without proto files Solution: Enable reflection in dev mode for all services Prevention: Make reflection mandatory in development builds

4. Async Runtime Blocking

Issue: ML Training Service accepts connections but never responds Impact: Complete service hang, requires kill -9 Solution: Requires detailed debugging with strace/tokio-console Prevention: Add request timeouts and health checks with deadlines
