*DistribCache uses Rust API configuration, not TOML

Verified Operations

HeliosDB Daemon Mode

• Starts in daemon mode and stays running
• Accepts PostgreSQL client connections
• Executes queries correctly
• Stops gracefully with SIGTERM
• Commit: 756e541 fixed daemon exit bug

HeliosProxy Pool Modes

• Parses pool-modes tutorial configuration
• Transaction pooling mode works correctly
• Multiple connections share backend pool
• Queries routed to backend successfully

HeliosProxy HA Configuration

• Parses HA failover tutorial configuration
• Health check configuration validated
• Node configuration with roles (primary/standby)
• Connection routing to primary node works

Test Execution Details

Test Environment

• HeliosDB backend on port 25550
• HeliosProxy on ports 25551 (pool-modes) and 25552 (HA)
• Health endpoint on port 28080

Pool Modes Tutorial Tests

-- Basic SELECT: PASS
SELECT 1 AS test_value;

-- Table operations: PASS
CREATE TABLE pool_test (id INT, name VARCHAR(50));
INSERT INTO pool_test VALUES (1, 'Transaction Pooling Works!');
SELECT * FROM pool_test;

-- Transaction boundaries: PASS
BEGIN; INSERT INTO pool_test VALUES (2, 'In Transaction'); COMMIT;

HA Failover Tutorial Tests

-- Basic routing: PASS
SELECT 1 AS ha_test;

-- Table operations through HA proxy: PASS
CREATE TABLE ha_test (id INT, msg VARCHAR(100));

-- Connection pooling under load: PASS
-- 5 rapid sequential connections all successful

DistribCache Tutorial Tests

• Tutorial script syntax validation: PASS
• Configuration example review: PASS
• Rust API documentation: Complete

Fixes Applied

1. Tutorial Configuration Fixes (Commit: 00600e4)

   • Fixed field names: listen_addr → listen_address
   • Fixed TOML syntax: [cluster].nodes → [[nodes]]
   • Added complete ProxyConfig structure

2. Daemon Mode Bug Fix (Commit: 756e541)

   • Added --daemon-child hidden flag
   • Use SIGTERM/SIGINT signal handlers for daemon mode
   • Keep ctrl_c() for interactive mode

Notes

• Port 8080 may conflict on some systems; use --http-port flag
• HeliosDB-Lite doesn’t implement pg_backend_pid() function
• Transaction handling may differ from PostgreSQL in edge cases

Commits

1. 00600e4 - fix: Update tutorial configurations to match ProxyConfig schema
2. 756e541 - fix: Daemon mode exits immediately - use SIGTERM signal handling
