# PostgreSQL Client Module Tests
The PostgreSQL client module provides functions for connecting to and interacting with PostgreSQL databases. These tests verify the functionality of the module.
## PostgreSQL Client Features
The PostgreSQL client module provides the following features:
1. **Basic PostgreSQL Operations**: Execute queries, fetch results, etc.
2. **Connection Management**: Automatic connection handling and reconnection
3. **Builder Pattern for Configuration**: Flexible configuration with authentication support
## Prerequisites
- PostgreSQL server must be running and accessible
- Environment variables should be set for connection details:
- `POSTGRES_HOST`: PostgreSQL server host (default: localhost)
- `POSTGRES_PORT`: PostgreSQL server port (default: 5432)
- `POSTGRES_USER`: PostgreSQL username (default: postgres)
- `POSTGRES_PASSWORD`: PostgreSQL password
- `POSTGRES_DB`: PostgreSQL database name (default: postgres)
## Test Files
### 01_postgres_connection.rhai
Tests basic PostgreSQL connection and operations:
- Connecting to PostgreSQL
- Pinging the server
- Creating a table
- Inserting data
- Querying data
- Dropping a table
- Resetting the connection
### run_all_tests.rhai
Runs all PostgreSQL client module tests and provides a summary of the results.
## Running the Tests
You can run the tests using the `herodo` command:
```bash
herodo --path src/rhai_tests/postgresclient/run_all_tests.rhai
```
Or run individual tests:
```bash
herodo --path src/rhai_tests/postgresclient/01_postgres_connection.rhai
```
## Available Functions
### Connection Functions
- `pg_connect()`: Connect to PostgreSQL using environment variables
- `pg_ping()`: Ping the PostgreSQL server to check if it's available
- `pg_reset()`: Reset the PostgreSQL client connection
### Query Functions
- `pg_execute(query)`: Execute a query and return the number of affected rows
- `pg_query(query)`: Execute a query and return the results as an array of maps
- `pg_query_one(query)`: Execute a query and return a single row as a map
## Authentication Support
The PostgreSQL client module will support authentication using the builder pattern in a future update.
The backend implementation is ready, but the Rhai bindings are still in development.
When implemented, the builder pattern will support the following configuration options:
- Host: Set the PostgreSQL host
- Port: Set the PostgreSQL port
- User: Set the PostgreSQL username
- Password: Set the PostgreSQL password
- Database: Set the PostgreSQL database name
- Application name: Set the application name
- Connection timeout: Set the connection timeout in seconds
- SSL mode: Set the SSL mode
## Example Usage
```javascript
// Connect to PostgreSQL
if (pg_connect()) {
print("Connected to PostgreSQL!");
// Create a table
let create_table_query = "CREATE TABLE IF NOT EXISTS test_table (id SERIAL PRIMARY KEY, name TEXT)";
pg_execute(create_table_query);
// Insert data
let insert_query = "INSERT INTO test_table (name) VALUES ('test')";
pg_execute(insert_query);
// Query data
let select_query = "SELECT * FROM test_table";
let results = pg_query(select_query);
// Process results
for (result in results) {
print(`ID: ${result.id}, Name: ${result.name}`);
}
// Clean up
let drop_query = "DROP TABLE test_table";
pg_execute(drop_query);
}
```

This document describes the test scripts for the Redis client module in the SAL library. These tests verify the functionality of the Redis client module's connection management and Redis operations.
## Redis Client Features
The Redis client module provides the following features:
1. **Basic Redis Operations**: SET, GET, DEL, etc.
2. **Hash Operations**: HSET, HGET, HGETALL, HDEL
3. **List Operations**: RPUSH, LPUSH, LLEN, LRANGE

# PostgreSQL Client Module
The PostgreSQL client module provides a simple and efficient way to interact with PostgreSQL databases in Rust. It offers connection management, query execution, and a builder pattern for flexible configuration.
## Features
- **Connection Management**: Automatic connection handling and reconnection
- **Query Execution**: Simple API for executing queries and fetching results
- **Builder Pattern**: Flexible configuration with authentication support
- **Environment Variable Support**: Easy configuration through environment variables
- **Thread Safety**: Safe to use in multi-threaded applications
## Usage
### Basic Usage
```rust
use sal::postgresclient::{execute, query, query_one};
// Execute a query
let create_table_query = "CREATE TABLE IF NOT EXISTS users (id SERIAL PRIMARY KEY, name TEXT)";
execute(create_table_query, &[]).expect("Failed to create table");
// Insert data
let insert_query = "INSERT INTO users (name) VALUES ($1) RETURNING id";
let rows = query(insert_query, &[&"John Doe"]).expect("Failed to insert data");
let id: i32 = rows[0].get(0);
// Query data
let select_query = "SELECT id, name FROM users WHERE id = $1";
let row = query_one(select_query, &[&id]).expect("Failed to query data");
let name: String = row.get(1);
println!("User: {} (ID: {})", name, id);
```
### Connection Management
The module manages connections automatically, but you can also reset the connection if needed:
```rust
use sal::postgresclient::reset;
// Reset the PostgreSQL client connection
reset().expect("Failed to reset connection");
```
### Builder Pattern
The module provides a builder pattern for flexible configuration:
```rust
use sal::postgresclient::{PostgresConfigBuilder, with_config};
// Create a configuration builder
let config = PostgresConfigBuilder::new()
.host("db.example.com")
.port(5432)
.user("postgres")
.password("secret")
.database("mydb")
.application_name("my-app")
.connect_timeout(30)
.ssl_mode("require");
// Connect with the configuration
let client = with_config(config).expect("Failed to connect");
```
## Configuration
### Environment Variables
The module uses the following environment variables for configuration:
- `POSTGRES_HOST`: PostgreSQL server host (default: localhost)
- `POSTGRES_PORT`: PostgreSQL server port (default: 5432)
- `POSTGRES_USER`: PostgreSQL username (default: postgres)
- `POSTGRES_PASSWORD`: PostgreSQL password
- `POSTGRES_DB`: PostgreSQL database name (default: postgres)
### Connection String
The connection string is built from the configuration options:
```
host=localhost port=5432 user=postgres dbname=postgres
```
With authentication:
```
host=localhost port=5432 user=postgres password=secret dbname=postgres
```
With additional options:
```
host=localhost port=5432 user=postgres dbname=postgres application_name=my-app connect_timeout=30 sslmode=require
```
## API Reference
### Connection Functions
- `get_postgres_client() -> Result<Arc<PostgresClientWrapper>, PostgresError>`: Get the PostgreSQL client instance
- `reset() -> Result<(), PostgresError>`: Reset the PostgreSQL client connection
### Query Functions
- `execute(query: &str, params: &[&(dyn postgres::types::ToSql + Sync)]) -> Result<u64, PostgresError>`: Execute a query and return the number of affected rows
- `query(query: &str, params: &[&(dyn postgres::types::ToSql + Sync)]) -> Result<Vec<Row>, PostgresError>`: Execute a query and return the results as a vector of rows
- `query_one(query: &str, params: &[&(dyn postgres::types::ToSql + Sync)]) -> Result<Row, PostgresError>`: Execute a query and return a single row
- `query_opt(query: &str, params: &[&(dyn postgres::types::ToSql + Sync)]) -> Result<Option<Row>, PostgresError>`: Execute a query and return an optional row
### Configuration Functions
- `PostgresConfigBuilder::new() -> PostgresConfigBuilder`: Create a new PostgreSQL configuration builder
- `with_config(config: PostgresConfigBuilder) -> Result<Client, PostgresError>`: Create a new PostgreSQL client with custom configuration
## Error Handling
The module uses the `postgres::Error` type for error handling:
```rust
use sal::postgresclient::{query, query_one};
// Handle errors
match query("SELECT * FROM users", &[]) {
Ok(rows) => {
println!("Found {} users", rows.len());
},
Err(e) => {
eprintln!("Error querying users: {}", e);
}
}
// Using query_one with no results
match query_one("SELECT * FROM users WHERE id = $1", &[&999]) {
Ok(_) => {
println!("User found");
},
Err(e) => {
eprintln!("User not found: {}", e);
}
}
```
## Thread Safety
The PostgreSQL client module is designed to be thread-safe. It uses `Arc` and `Mutex` to ensure safe concurrent access to the client instance.
## Examples
### Basic CRUD Operations
```rust
use sal::postgresclient::{execute, query, query_one};
// Create
let create_query = "INSERT INTO users (name, email) VALUES ($1, $2) RETURNING id";
let rows = query(create_query, &[&"Alice", &"alice@example.com"]).expect("Failed to create user");
let id: i32 = rows[0].get(0);
// Read
let read_query = "SELECT id, name, email FROM users WHERE id = $1";
let row = query_one(read_query, &[&id]).expect("Failed to read user");
let name: String = row.get(1);
let email: String = row.get(2);
// Update
let update_query = "UPDATE users SET email = $1 WHERE id = $2";
let affected = execute(update_query, &[&"new.alice@example.com", &id]).expect("Failed to update user");
// Delete
let delete_query = "DELETE FROM users WHERE id = $1";
let affected = execute(delete_query, &[&id]).expect("Failed to delete user");
```
### Transactions
Transactions are not directly supported by the module, but you can use the PostgreSQL client to implement them:
```rust
use sal::postgresclient::{execute, query};
// Start a transaction
execute("BEGIN", &[]).expect("Failed to start transaction");
// Perform operations
let insert_query = "INSERT INTO accounts (user_id, balance) VALUES ($1, $2)";
execute(insert_query, &[&1, &1000.0]).expect("Failed to insert account");
let update_query = "UPDATE users SET has_account = TRUE WHERE id = $1";
execute(update_query, &[&1]).expect("Failed to update user");
// Commit the transaction
execute("COMMIT", &[]).expect("Failed to commit transaction");
// Or rollback in case of an error
// execute("ROLLBACK", &[]).expect("Failed to rollback transaction");
```
## Testing
The module includes comprehensive tests for both unit and integration testing:
```rust
// Unit tests
#[test]
fn test_postgres_config_builder() {
let config = PostgresConfigBuilder::new()
.host("test-host")
.port(5433)
.user("test-user");
let conn_string = config.build_connection_string();
assert!(conn_string.contains("host=test-host"));
assert!(conn_string.contains("port=5433"));
assert!(conn_string.contains("user=test-user"));
}
// Integration tests
#[test]
fn test_basic_postgres_operations() {
// Skip if PostgreSQL is not available
if !is_postgres_available() {
return;
}
// Create a test table
let create_table_query = "CREATE TEMPORARY TABLE test_table (id SERIAL PRIMARY KEY, name TEXT)";
execute(create_table_query, &[]).expect("Failed to create table");
// Insert data
let insert_query = "INSERT INTO test_table (name) VALUES ($1) RETURNING id";
let rows = query(insert_query, &[&"test"]).expect("Failed to insert data");
let id: i32 = rows[0].get(0);
// Query data
let select_query = "SELECT name FROM test_table WHERE id = $1";
let row = query_one(select_query, &[&id]).expect("Failed to query data");
let name: String = row.get(0);
assert_eq!(name, "test");
}
```

- **Flexible Connectivity**:
- **Flexible Connectivity**:
- Tries Unix socket connection first (`$HOME/hero/var/myredis.sock`)
- Falls back to TCP connection (localhost) if socket connection fails
- **Database Selection**: Uses the `REDISDB` environment variable to select the Redis database (defaults to 0)
- **Authentication Support**: Supports username/password authentication
- **Builder Pattern**: Flexible configuration with a builder pattern
- **TLS Support**: Optional TLS encryption for secure connections
- **Error Handling**: Comprehensive error handling with detailed error messages
- **Thread Safety**: Safe to use in multi-threaded applications

### Builder Pattern
The module provides a builder pattern for flexible configuration:
```rust
use crate::redisclient::{RedisConfigBuilder, with_config};
// Create a configuration builder
let config = RedisConfigBuilder::new()
.host("redis.example.com")
.port(6379)
.db(1)
.username("user")
.password("secret")
.use_tls(true)
.connection_timeout(30);
// Connect with the configuration
let client = with_config(config)?;
```
### Unix Socket Connection
You can explicitly configure a Unix socket connection:
```rust
use crate::redisclient::{RedisConfigBuilder, with_config};
// Create a configuration builder for Unix socket
let config = RedisConfigBuilder::new()
.use_unix_socket(true)
.socket_path("/path/to/redis.sock")
.db(1);
// Connect with the configuration
let client = with_config(config)?;
```
## Environment Variables
- `REDISDB`: Specifies the Redis database number to use (default: 0)
- `REDIS_HOST`: Specifies the Redis host (default: 127.0.0.1)
- `REDIS_PORT`: Specifies the Redis port (default: 6379)
- `REDIS_USERNAME`: Specifies the Redis username for authentication
- `REDIS_PASSWORD`: Specifies the Redis password for authentication
- `HOME`: Used to determine the path to the Redis Unix socket
## Connection Strategy
@@ -77,6 +122,25 @@ The module includes both unit tests and integration tests:
- Integration tests that require a real Redis server
- Tests automatically skip if Redis is not available
### Unit Tests
- Tests for the builder pattern and configuration
- Tests for connection URL building
- Tests for environment variable handling
### Integration Tests
- Tests for basic Redis operations (SET, GET, EXPIRE)
- Tests for hash operations (HSET, HGET, HGETALL, HDEL)
- Tests for list operations (RPUSH, LLEN, LRANGE, LPOP)
- Tests for error handling (invalid commands, wrong data types)
Run the tests with:
```bash
cargo test --lib redisclient::tests
```
## Thread Safety
The Redis client is wrapped in an `Arc<Mutex<>>` to ensure thread safety when accessing the global instance.
