Welcome to your comprehensive guide on Libasynql, an asynchronous SQL access library designed specifically for PocketMine plugins. In this article, we’ll explore its features, set it up seamlessly, and tackle some common troubleshooting issues along the way! Let’s dive in!

What is Libasynql and Why Use It?

Libasynql is like a turbocharger for your plugin’s database queries. Imagine you’re at a restaurant waiting for your food to be served while the chef prepares your dish. If everything happens in a queue, you’ll be sitting there like a patient customer, but the entire process would be slow. This mirrors what happens when SQL queries are executed on the main thread; they block the server from running other tasks.

By utilizing Libasynql, you can run your SQL queries on different threads, ensuring that the main thread remains unhindered, resulting in a lag-free experience for your server. In simpler terms, it lets your chef cook while you serve other tables!

Getting Started with Libasynql: A Step-by-Step Guide

Using Libasynql involves a straightforward five-step process:

1. Add default database settings in config.yml.
2. Write down all the SQL queries in a resource file.
3. Initialize the database in onEnable().
4. Finalize the database in onDisable().
5. Incorporate Libasynql in your code.

Configuration

To prepare for Libasynql usage, insert the following configuration into your config.yml:

database:
  type: sqlite
  sqlite:
    file: data.sqlite
  mysql:
    host: 127.0.0.1
    username: root
    password: 
    schema: your_schema
  worker-limit: 1

This configuration allows users to choose the database type, whether SQLite or MySQL. The editor must replace schema names with their desired database schema.

Initialization and Finalization

Initialization is as simple as calling one function in your onEnable() method:

use pocketmine\plugin\PluginBase;
use poggit\libasynql\libasynql;

class Main extends PluginBase {
    private $database;

    public function onEnable() {
        $this->saveDefaultConfig();
        $this->database = libasynql::create($this, $this->getConfig()->get("database"), [
            "sqlite" => "sqlite.sql",
            "mysql" => "mysql.sql"
        ]);
    }

    public function onDisable() {
        if (isset($this->database)) {
            $this->database->close();
        }
    }
}

This initializes your database connection; be sure to check the connection’s status before closing it in onDisable.

Creating SQL Files

SQL files should reside within the resources folder. For example, create files such as resources/sqlite.sql and resources/mysql.sql. Remember to write all SQL queries using the Prepared Statement File format.

Calling Libasynql Functions

Now that everything is configured, it’s time to execute queries! You can perform operations using four modes: GENERIC, CHANGE, INSERT, and SELECT. Think of them as different ways to order at a restaurant:

• GENERIC: Just let the server know if the order was successful.
• CHANGE: Inform how many plates were modified, like in an eat-and-replace scenario.
• INSERT: Reserve auto-increment IDs, akin to booking seats for a large party.
• SELECT: Pick from the menu, expecting a return of dish options.

Troubleshooting Common Issues

While everything can be quite straightforward, issues might arise. Here are a few common problems and their solutions:

• Database Connection Issues: Ensure all your credentials in config.yml are accurate and that your database server is running.
• Query Syntax Errors: Errors in your SQL syntax will prevent queries from executing. Double-check your SQL files for any mistakes.
• Threading Problems: Mismanagement of callbacks can lead to confusing results. Always think about the order in which your functions are run and their scopes.
